Abstract

The present article describes the ongoing (partial) remission of a female patient (41 years old) from estrogen receptor (ER)-positive/progesterone receptor (PR)-negative metastatic breast cancer in response to a combination treatment directed towards the revitalization of the mitochondrial respiratory chain (oxidative phosphorylation), the suppression of NF-kappaB as a factor triggering the inflammatory response, and chemotherapy with capecitabine. The reduction of tumor mass was evidenced by a continuing decline of CA15-3 and CEA tumor marker serum levels and 18FDG-PET-CT plus magnetic resonance (MR) imaging. It is concluded that such combination treatment might be a useful option for treating already formed metastases and for providing protection against the formation of metastases in ER positive breast cancer. The findings need to be corroborated by clinical trials. Whether similar results can be expected for other malignant tumor phenotypes relying on glycolysis as the main energy source remains to be elucidated.

1. Introduction

Since Richard Nixon declared war on cancer about 30 years ago, much efforts have been made in order to overcome this dreadful disease. Enormous financial resources have been invested in cancer research in the last three decades, yet most metastasized solid malignant tumors are still considered incurable. Chemotherapy has been shown to be a potent (long lasting) treatment option against only a few solid cancers including testis cancer. The overall contribution of curative and adjuvant cytotoxic chemotherapy was assessed to be 2.3% in Australia and 2.1% in the United States of America with a five-year survival in adults based on data for 1998 []. Under chemotherapy, cancer cells can gradually develop drug resistance that is acquired, for instance, by overexpression of transporter proteins (e.g., those belonging to the ATP-binding cassette type) [,] and fractionation of the cancerous stem cells [] (which are less sensitive to exposure to cytostatics than more differentiated cancer cells), plus AKT [,] and NF-kappaB [,] overexpression as a compensatory response to administered cytotoxic drugs. Likewise, induced hypoxia may act as protective shield against tumor eradication by chemotherapeutics and radiation due to alterations of gene expression profiles related to hypoxia, which result in the inhibition of apoptosis [].

On the other hand, a plethora of “alternative” cancer therapies have been developed and applied in the past. Here, we report on a combination treatment, including chemotherapy, bisphosphonates, and complementary measures, aiming at the normalization of the cellular metabolism, vascular angiogenesis, cell life cycle, and cell proliferation activity.

Vitamin D and vitamin A were sporadically taken.

2.2. Procedure

The mentioned chemicals/dietary supplements have been taken as follows:

Alkalized drinking water was prepared ad lib by using water ion exchanger and filter. The filtered water was boiled prior to use.

Capecitabine was taken orally at 3.65 g Xeloda®/70 kg body weight per day. Two weeks of treatment were followed by one week of therapy pause per cycle.

“Budwig diet”: the following items were mixed for preparing a full batch using a blender: 1 kg Bio-Yoghurt, 0.1% fat, 0.25 kg Bio-Kefir, 1.5% fat, 6 table spoons of linseed oil, 4 table spoons of linseed, to be freshly milled: A part of this full batch may be prepared daily (the daily dose per person was about 250 grams).

Taken together around noon: 400 mg of Ubiquinol CoQ10 (4 capsules à 100 mg), 10 mg vitamin B2 (Riboflavin), 50 mg vitamin B3 (Niacin)

Taken three times daily: 2 softgels of MEGA EPA/DHA (eicosapentaenoic acid/docosahexaenoic acid), including 720 mg of EPA and 480 mg of DHA per 2 capsules.

One capsule of 5-Loxin®, one dose of Multinorm® L-Carnitin aktiv (taken only during chemotherapy pause; during the chemotherapy 300 mg pure L-carnitine not containing vitamin B12 was ingested), one tablet of Unizink® 50, and one tablet of Selenase®200 XXL were taken daily. EPA/DHA are COX-2 inhibitors. Therefore, the heart and vascular functions should be checked by a physician on a regular basis (it has been found that members of synthetic COX-2 inhibitors have been found to increase thrombosis, stroke, and heart attack risk under certain conditions). Moreover, Q10/B2/B3 were not taken in combination with radiation (the antioxidant Q10 potentially quenches the oxidative damage caused by radiation). EPA and DHA have potentially blood thinning effect.

3. Results

3.1. Applied Methodology and Methods

It has been hypothesized by the author that a multi-factorial approach towards breast cancer treatment would result in a synergetic response and reduced likelihood of development of resistance to treatment. Accordingly, it was sought to combine complementary, non-antagonistic treatments, which have the theoretical potential to suppress tumorigenesis and proliferation, with a “conventional” treatment. The envisaged therapy modules were Budwig diet and normalization of the fatty acid dietary balance, alkaline therapy, suppression of the inflammatory signaling chain, revitalization of the mitochondrial respiratory chain, bone protection against osteoclast-effected resorption by bisphosphonates and AKBA, and finally chemotherapy in the form of the prodrug capecitabine as 5-fluorouracil precursor []. The latter has been the recommended treatment by the medical tumor board in charge.

The described efforts have concretely been undertaken for suppressing refractory breast cancer stage IV in a female patient (body mass index 24–26, 41 years old), having developed a ductal carcinoma in situ in 2007. After biopsy revealed an estrogen receptor positive and progesterone receptor negative breast cancer, followed by surgical resection of the invaded sentinel lymph nodes, a neoadjuvant chemotherapy (four cycles Epirubicin/Cyclophosphamide, followed by four cycles of Taxotere®) was applied. However, the tumor showed little response (the tumor regression grade according to Sinn was only 1). Thus, the first and second axillary lymph node levels were resected in the following, and the affected breast was ablated. No suspicious tumor marker levels have been observed after ablation. The resection area was furthermore treated with radiation (gamma rays). The post-operational therapy included firstly tamoxifen, clodronate (a bisphosphonate), and a GNRH analogue (Enantone-Gyn®).

However, in September 2008, the patient – alerted by pain in the spinal cord – underwent MRI imaging, which revealed multiple bone metastases, including in the spinal cord.

As a consequence, the medication was altered as follows by the medical board in charge: Letrozol (aromatase inhibitor, 2.5 mg/d) and Ibandronat (6 mg intravenous infusion per month) as bisphosphonate. However, the disease progressed and a staging (18FDG-PET-CT and MRI) in March 2009 revealed the formation of various liver metastases. Therefore, the medication was changed to capecitabine chemotherapy instead of anti-hormonal therapy, accompanied by continuation of administration of Ibandronat.

Together with this therapy change, the author recommended the complimentary ingestion of the following substances: “Budwig diet” (linseed oil, flaxseed, and yoghurt), EPA/DHA concentrate in the form of distilled fish oil, ubiquinol (Q10 in reduced form), and vitamins B2 and B3, later on also 5-Loxin®(AKBA). See above for further dosage and substance specifications.

3.2. Results

After about three months (June 2009) of continued intake of the above mentioned substances (besides 5-Loxin®), PET-CT showed no metabolic activity of the liver metastases any longer and reduced activity of the bone metastases under 18F-deoxyglucose as tracer in the PET. Concurrently, a decline of the tumor markers’ (CA 15-3 and CEA) serum concentration was observed.

At this time, as a further element, 5-Loxin® (AKBA) was introduced into the supplementation scheme for the reasons mentioned.

Nine months later, the MRI showed that three out of six initial liver metastases could no longer be imaged, and that the largest lesion had decreased from about 15 mm to about 7 mm. A further small liver metastasis remained unchanged in size. This situation is depicted in Figure 1. Again, no metabolic activity in 18FDG-PET-CT was detected for any of the liver metastases.

One metastasis (arrow) decreased from 15 mm in diameter to 7 mm, while the other remained unchanged (courtesy of Prof. Dr. E. Rummeny, Klinikum Rechts der Isar, Technische Universität München, Technical University of Munich, Germany).

Moreover, the PET-CT (18F-deoxyglucose as PET tracer) showed, in addition, a reduction of the size and metabolic activity of bone metastases, accompanied by re-calcification of the lesions. The response to treatment correlated with markedly decreased tumor marker serum levels, with CEA concentration being close to the significance threshold of 4 ng/mL. The development of the tumor marker levels over time is displayed in Table 1 below. The decline of tumor marker concentrations has been found to correlate with cancer remission in clinical studies on breast cancer patients [,]. In addition, the initial concentration of CEA has been associated with the clinical disease outcome in breast cancer patients.

Date/Months after Therapy Start CA 15-3 (U/mL) Excess over Cut-off Value [%] CEA (ng/mL) Excess over Cut-off Value [%]
29 June 2009/3 49.3 82.6 31.4 684
13 September 2009/7 46.2 71.1 8.4 110
11 January 2010/10 37 37.0 4.1 2.5
19 April 2010/13 38.3 41.9 3.6 -10.8
12 July 2010/16 35.7 32.3 4.1 1.5

The latest 18FDG-PET-CT of August 2010 showed ongoing sclerosis of at least some of the bone lesions and stable disease.

4. Discussion and Conclusions

A plethora of complementary cancer treatments have been reported. Firstly, the intake of polysaccharides and proteoglucans, such as mushroom and yeast glucans [  ,  ], mistletoe lectins [,] and nerium oleander extracts, the latter also in combination with sutherlandia frutescens extracts [,], have been described. The activation of the immune system against cancer cells has been ascribed to all of these compounds.

Another approach employed against the proliferation of cancer is alkaline therapy, which addresses the cellular acid-base balance. It has been found that extracellular/interstitial cancer tissue is more acidic than healthy tissue due to excessive production of lactic acid stemming from the glycolysis of glucose []. Otto Warburg already suggested in the last century that (as a consequence of hypoxia often encountered in tumor tissues) cancer cells undergo excessive glycolysis instead of relying on the energetically by far more effective oxidative phosphorylation [,], a fact which could recently also be verified by biopsy analysis in breast cancer patients, revealing a marked decrease in β-F1-ATPase/HSP60 expression ratio during disease progression []. Lately, it has been suggested that the initiation of glycolysis could be triggered by AKT activation during tumor development [] and that the resulting acidification of the extra-cellular cancer tissue brings about survival advantages for cancer cells [,]. It has been found recently that T-cell development is markedly suppressed in acidified cancer tissue []. Alternative alkaline therapies applied for cancer treatment included the intake of sodium bicarbonate [], cesium chloride [], or alkaline diet, which is based on fruit and vegetables having high potassium content. A further approach was the ingestion of alkaline drinking water obtained from ion exchangers.

Another avenue towards cancer suppression has been established by the supplementation of (essential) polyunsaturated fatty acids, aiming at re-establishing cellular membrane functionality [] and fluidity []. In addition, the polyunsaturated omega-3 fatty acids eicosapentaenoic (EPA) and docosapentaenoic acid (DHA) have been found to have a direct bearing on gene expression level by e.g., deactivation of NF-kappaB and AKT by EPA and DHA in a mouse model []. Polyunsaturated omega-3 fatty acids have also been shown to possess anti-inflammatory properties, for instance. by suppression of NF-KappaB and cyclooxygenases [], or caused by the reduction of prostaglandin E2 biosynthesis via arachidonic acid due to a shift in the omega-6 fatty acid/omega-3 FA level towards omega-3 species (omega-6 fatty acids form the pool for the endogenous biosynthesis of E2 prostaglandin) [,].

In addition, a direct positive correlation between cytotoxic drug efficacy and DHA level in breast adipose tissue of patients has been observed [  ]. Also, recent clinical studies suggested that EPA/DHA supplementation may suppress cancer-related cachexia []. Whereas severe side effects have been reported for the prolonged administration of some synthetic COX-II inhibitors, including increased thrombosis, stroke, and heart attack risk, to our best knowledge no comparably grave effects have been reported for the prolonged intake of EPA/DHA (e.g. in the form of fish oil) in clinical studies. The side effects of fish oil therapy, including blood thinning, have recently been discussed, e.g., by Farooqui et al.[].

Likewise, Johanna Budwig established a cancer diet (the so-called “Budwig diet”), which includes inter alia the daily intake of linseed oil as a potent source of alpha-linolenic acid as essential omega-3 fatty acid []. Anecdotal cases of complete cancer remissions after continued Budwig diet have been reported []. To our best knowledge, no randomized clinical trials exploring the efficacy of the Budwig diet have been launched to date. The consequence of a continued Budwig diet is said to be an optimization of the dietary balance of omega-6/omega-3 fatty acids and reconstitution of physiologically intact cellular membrane composition by enhanced administration of polyunsaturated fatty acids as a substitute for peroxidized and saturated fatty acids in cellular membranes, thus increasing membrane fluidity. Furthermore, it has been hypothesized that polyunsaturated fatty acids may act as oxygen carriers []. The present-day Western diet results in an adverse ratio of about 15:1 of omega-6/omega-3 fatty acids, whereas a ratio of about 1:1 has been reported as paleolithic reference value for humans []. As a consequence, the endogenous high level of omega-6 fatty acids in humans fosters the increased biosynthesis of pro-inflammatory arachidonic acid from e.g., linoleic acid. Moreover, it has been hypothesized that cottage cheese, quark or yoghurt as second constituent of the Budwig diet refills the pool of sulfhydryl amino acids (which are essential for glutathione biosynthesis).

Warburg considered the glycolytic switch as being a final event in cancer formation, accompanied by irreversible genetic changes and the inactivation of the mitochondrial respiratory chain in cells, giving rise to their dedifferentiation []. However, recent studies suggest that this may not be the case: Dichloroacetate has been shown to be a potent inhibitor of pyruvate dehydrogenase kinase, thereby suppressing, as other agents, the glycolytic switch and thus fostering oxidative phosphorylation [,,]. As a consequence of such an apparent normalization of the cellular energy production, cancer remissions in animal trials and anecdotal reports of healing of malignant tumors in human patients have been reported lately [].

Moreover, investigations involving the administration of coenzyme Q10 directed towards the revitalization of the mitochondrial respiratory chain suggest that, indeed, the inhibition of the respiratory chain (Q10 is present in various complexes thereof) can be reversed or at least be halted: Folkers et al. reported that breast cancer patients taking 90 mg per day Q10 stayed in a state of constant disease, and did not develop new metastases. No patient in the group died, although about 20% (6/32) deaths were statistically expected in the observation period. When the dose of Q10 was augmented to 390 mg daily, five patients who already showed remission under 90 mg of Q10 per day went into apparently complete remission, including the eradication of liver metastases [,]. Cases of complete remission in response to high doses of Q10 for other cancer types, such as small cell bronchogenic carcinoma, have also been published by Folkers et al.[].

Likewise, Sachdanandam et al. recently reported on tumor control and remission caused by a combination treatment by coenzyme Q10, vitamins B2 and B3 (all of which are essential for the cellular energy generation) and tamoxifen in animal trials []. As a result, markedly lower levels of lipid peroxidation and cachexia over the tumor-induced non-treated control group was observed. Orienting clinical trials of Premkumar et al., involving 84 breast cancer patients, affirmed the anti-tumor action of said agent combination []. Inter alia, a decrease of the plasma concentration of urokinase plasminogen activator (UPA) by about 50% was observed, and the level of adhesion factors such as E-selectin and pro-angiogenic proteinase MMP-9 were found to be drastically decreased after only 90 days of treatment. Moreover, significantly reduced tumor marker levels (CA-15-3 and CEA) have been measured after 90 days of coenzyme Q10, vitamins B2 and B3 plus tamoxifen combination treatment []. UPA expression level was determined as correlating with the clinical outcome of breast cancer, and UPA inhibition has therefore been made the target of extensive research [].

Another approach addressing the stabilization of the course of breast cancer is the administration of bisphosphonates [] such as ibandronate, which stabilize the bone matrix and thus impede osteoclast-mediated bone lysis. In addition, certain bisphosphonates, such as the latter compound, have been shown to possess direct anti-tumor action in vitro and in vivo [,].

Finally, a further route towards the suppression of cancers is the suppression of nuclear factor kappa B (a gene transcription promoter involved in the inflammatory chain and in a tumor’s capability to invade, metastasize and evade apoptosis) []. NF-kappaB stimulates the expression of various pro-inflammatory genes [,], also in breast cancer []. Consequently, a number of approaches have been divulged lately which are concerned with inhibition of this factor. The different compounds, which hinder the activation of NF-kappaB, are e.g., EPA (see above), and 11-keto-17-hydroxy boswellic acid (AKBA) [], a compound which has been shown to abrogate the osteoclastogenesis by inhibition of NF-kappaB activation in vitro. AKBA was also shown to hinder the enzyme 5-lipoxygenase [], which plays a pivotal role in the biosynthesis of pro-inflammatory leucotrienes. Remarkably, it has been shown that NF-kappaB inhibitors effectively inhibited MCF-7 breast cancer stem-like cells [].

In the present case, refractory breast cancer, which had not or has poorly responded to initial chemo- and anti-hormonal therapy, showed drastic and ongoing response to a combination treatment including capecitabine and complementary treatment components; the latter include NF-kappaB blockers, and other inhibitors of the inflammatory chain, respiratory chain stimulants, plus alkaline therapy. The rationale for employing these agents has been explained in the preceding paragraphs. No resistance to the therapy was observed after 17 months, and the decrease of tumor marker levels correlated with imaging results. The obtained results are significant in view of the initial heavy disease progress and lack of relevant response to all preceding therapies.

The incremental contributions of each individual treatment element remain unclear. However, it is hypothesized that a synergetic action of the measures takes place. These have been selected by theoretical considerations in order to avoid potential antagonistic interferences, which could annihilate action. It should also be noted that concerns about the simultaneous intake of chemotherapeutics and antioxidants have been raised in the literature, especially in the context of cytostatics that have free radical formation as their believed primary mechanism of action. To our best knowledge, the primary mechanism of action of capecitabine, however, is not via free radicals but DNA synthesis and thymidylate synthase inhibition []. No antagonistic interaction with the remaining measures “base therapy” (addressing the immune suppression observed in the acidic tumor environment due to the purported suppression of T-cell development in the acidic tissue adjacent to tumors) and bone stabilization by bisphosphonates has been expected. On the contrary, the reported suppression of NF-kappaB expression by e.g. AKBA should reduce the RANKL-induced osteoclastogenesis, which is triggered by the transcription factor NF-kappaB [].

Whether all measures contribute to the observed results remains speculative. The progression-free interval of 17 months observed so far is encouraging in view of a median time to progression from 3–9 months reported for the first line treatment of metastatic breast cancer by capecitabine []. Randomized clinical trials appear to be indicated in view of the promising orienting results.

Note that ER positive/PR negative breast cancer constitutes a rather limited high risk subset within the broader patient collective suffering from luminal breast cancer. Lately, it has been hypothesized in the literature that the expression of progesterone receptor (genes) in breast cancer has a positive bearing on the disease malignity and outcome, correlating with a less aggressive phenotype, and that the expression of progesterone receptor genes may be hindered by AP-1 [,,]. AP-1 and NF-kappaB have been shown to bind to UPA promoter sequence and to cooperatively foster UPA expression. Consequently, it has been directly or indirectly suggested to therapeutically inhibit NF-kappaB in order to improve efficacy of antiestrogen treatment of patients associated to high risk hormone-dependent breast cancer [,].

Moreover, the reduced UPA expression mediated by Q10 described in the literature could also be a sign of a reduced activity of the transcription factor AP-1. At the same time, reduction of AP-1 activity could lead to a reversal of the blockage of the progesterone receptor expression caused by the inhibitory action of AP-1 and a consequent sensitization of ER-positive/PR-negative breast cancers to anti-estrogenic treatment by tamoxifen (compare to references [,]).

It is further hypothesized that the obtained orienting results hint (as already observed for DCA) at a revitalization of the mitochondrial respiratory chain at the expense of a pathologic increase of glycolysis. The reduction of glucose metabolism of the metastases was corroborated by reduced signal intensity in 18FDG-PET-CT scans during the treatment. Hence, the results are interpreted as a pointer towards the (at least partial) reversibility of the glycolytic switch and the associated changes in gene profile expression.

Effects of drinking molecular hydrogen water on the quality of life QOL of cancer patients treated with RADIATION therapy

Effects of drinking molecular hydrogen water on the quality of life of cancer patients treated with radiation therapy

This is the first report demonstrating the benefits of drinking molecular hydrogen water in liver cancer patients receiving radiation therapy for malignant tumors.
– Molecular hydrogen dissolved in water improved the QOL of (liver) cancer patients reciving radiotherapy
– Molecular hydrogen water mitigated oxidative stress marker during radiotherapy
– Molecular hydrogen water did NOT compromise the radiation cancer treatment efficacies
-Molecular hydrogen water treatment did NOT alter liver function or blood composition during radiotherapy

This study examined whether molecular hydrogen (dissolved in water ) treatment, improved QOL in patients receiving radiotherapy.

Cancer patients receiving radiotherapy often experience fatigue and impaired quality of life (QOL).

Most radiation-induced symptoms are believed to be associated with increased oxidative stress and inflammation, due to the generation of reactive oxygen species (ROS) during radiotherapy, and may significantly affect the patient’s quality of life (QOL) [].

Molecular hydrogen (dissolve in water) can be administered as a therapeutic medical gas, has selective ANTIoxidant( molecular hydrogen ( water ) neutralizes only bad free radicals while supporting the beneficial ones)  & ANTIinflammatory (molecular hydrogen( water )reduces inflammation in tisues) properties.

Drinking liquids(i.e. : water) with dissolved molecular hydrogen represents a novel method of molecular hydrogen gas delivery that is easily translatable into clinical practice, with beneficial effects for several medical conditions, including atherosclerosis, type 2 diabetes, metabolic syndrome, and cognitive impairment during aging and in Parkinson’s disease [].

Methods

A randomized, placebo-controlled study was performed to evaluate the effects of drinking molecular hydrogen-rich water on 49 patients receiving radiotherapy for malignant liver tumors.

The subjects were randomly assigned to groups to either drink molecular hydrogen-rich water for 6 weeks (n = 25) or drink water containing a placebo (n = 24).

Subjects were provided with four 500 mL bottles of drinking molecular hydrogen water per day .

Molecular hydrogen rich water had final molecular hydrogen concentration; 0.55~0.65 mM.

The subjects were expected to consume 100-300 mL of molecular hydrogen-rich water more than 10 times per day for a total minimum consumption of 1500 mL (1.5 L) and a maximum consumption of 2000 mL (2.0 L).

Oral intake of molecular hydrogen water or placebo water started on the first day of radiotherapy and continued for 6 weeks.

All participants received 5040-6500 cGy of radiotherapy for 7-8 weeks using a 6 MV system (Cyber Knife, Fanuc, Yamanashi, Japan).

Table 1

Patient Characteristics

All the liver cancer patients survived through the 6 week follow-up period when the QOL questionnaire was administered.

The Korean version of the European Organization for Research and Treatment of Cancer’s QLQ-C30 instrument was used to evaluate global health status and QOL. The concentration of derivatives of reactive oxidative metabolites and biological antioxidant power in the peripheral blood were assessed.

Results & Conclusions

The consumption of molecular hydrogen-rich water for 6 weeks reduced reactive oxygen metabolites in the blood and maintained blood oxidation potential. QOL scores during radiotherapy were SIGNIFICANTLY IMPROVED in patients treated with molecular hydrogen-rich water compared to patients receiving placebo water.

There was no difference in tumor response to radiotherapy between the two groups( meaning drinking molecular hydrogen water did not interfere with the desired antitumor effects of radiation therapy ).

Daily consumption of molecular hydrogen-rich water is a potentially novel, therapeutic strategy for improving QOL after radiation exposure.

Consumption of hydrogen-rich water reduces the biological reaction to radiation-induced oxidative stress without compromising anti-tumor effects.

Molecular hydrogen dissolved in water improved the QOL of (liver) cancer patients receiving radiotherapy

The QOL of the liver cancer patients who were given placebo water deteriorated significantly within the first month of radiotherapy (Figure1A)

Gastrointestinal (GI) symptoms are one of the most common complaints of patients undergoing radiotherapy and are considered to have a high impact on the patient’s QOL after 6 weeks of radiotherapy.

The patients consuming molecular hydrogen water experienced significantly less appetite loss and fewer tasting disorders compared to the patients consuming placebo water.

Liver cancer patients experience GI symptoms and decreased QOL during radiotherapy. These symptoms usually occur as a result of the body repairing damage to healthy cells, are particularly common towards the end of a course of radiation treatment, and can last for some time. The symptoms and their impact on QOL can be worsened by having to travel to the hospital each day.

Drinking molecular hydrogen-rich water improved the QOL of the liver cancer patients receiving radiotherapy and did not require additional hospital visits.

There were no differences between the groups in the QOL subscales for fatigue, depression, or sleep. No significant difference was seen in the mean scores for vomiting or diarrhea (Figure1B).

Molecular hydrogen water mitigated oxidative stress marker during radiotherapy

Before treatment, there were no differences in total hydroperoxide levels, representative of total dROM levels, between the treatment groups.

Radiotherapy markedly increased total hydroperoxide levels in the patients consuming placebo water.

However, drinking molecular hydrogen water prevented this increase in total serum hydroperoxide, as determined by the dROM test (Figure2A), indicating DECREASED OXIDATIVE STRESS during radiotherapy in the liver cancer patients who consumed molecular hydrogen water.

Similarly, endogenous serum antioxidant activity significantly deteriorated during radiotherapy in the patients consuming placebo water, and biologic antioxidant activity was MAINTAINED in liver cancer patients who consumed molecular hydrogen-rich water, even after 6 weeks of radiotherapy (Figure2B).

Previous experimental studies have linked daily consumption of molecular hydrogen-rich water with improvement of a number of conditions in rodent models, including reducing atherosclerosis in apolipoprotein E knockout mice [], alleviating cisplatin(chemotherapy)-induced nephrotoxicity [], reducing vitamin C deficiency-induced brain injury [], preventing chronic allograft nephropathy after renal transplantation [], and ameliorating cognitive defects in senescence-accelerated mice [] and a Parkinson’s disease model []. In human studies, consumption of molecular hydrogen-rich water prevented adult-onset diabetes and insulin resistance [], as well as oxidative stress in potential metabolic syndrome [].

Radiotherapy is associated with an increase in ROS, followed by damage to DNA, lipids, and proteins, and activation of transcription factors and signal transduction pathways. It has been estimated that 60-70% of the ionizing radiation-induced cellular damage is caused by hydroxyl radicals [].

Therefore, a number of trials with the goal of reducing adverse effects due to excess ROS production have been performed with antioxidants delivered during the course of radiotherapy. Supplementation with α-tocopherol improves the salivary flow rate and maintains salivary parameters []. Treatment with the antioxidant enzyme superoxide dismutase prevented radiotherapy-induced cystitis and rectitis in bladder cancer patients receiving radiotherapy []. In addition, the combined use of pentoxifylline and vitamin E reduced radiation-induced lung fibrosis in patients with lung cancer receiving radiotherapy [].

Thus, in general, supplementation with antioxidants is likely to offer overall benefits in the treatment of adverse effects of radiotherapy.

However, not all antioxidants can afford radioprotection [].

Furthermore, of significant concern is the finding that high doses of antioxidants administered as adjuvant therapy might compromise the efficacy of radiation treatment and increase of the risk of local recurrence of cancer [,].

Hence, the relatively lower toxicity associated with the use of these antioxidant agents is appealing, but not at the cost of poor tumor control.

In contrast, in this study, drinking molecular hydrogen-rich water did NOT affect radiotherapy’s anti-tumor effects.

Molecular hydrogen water did NOT compromise the radiation cancer treatment efficacies

Tumor response to radiotherapy was similar between the cancer treatment groups, and 12 of 24 (50.0%)  liver cancer patients in the placebo group and 12 of 25 (48%) patients in molecular hydrogen water group exhibited either a completed response (CR) or a partial response (PR). There were no patients in either group with progressive disease (PD) during the follow-up period (3 months). Thus, drinking molecular hydrogen water did  NOT compromise the anti-tumor effects of radiotherapy.

Our results may suggest that hydrogen water functions not only as an antioxidant, but also plays a protective role by inducing radioprotective hormones or enzymes. 

Molecular hydrogen water treatment did NOT alter liver function or blood composition during radiotherapy

There were no significant differences in aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase (γ-GTP) and total cholesterol levels at week 0 and week 6, regardless of the type of water consumed(Table2), indicating that molecular hydrogen water consumption did NOT alter liver function.

Similarly, there were no significant differences in red blood cell count, white blood cell count, or platelet count between patients consuming molecular hydrogen water and patients consuming placebo water (Table3).

This finding may provide the foundation for a clinically applicable, effective, and safe strategy for the delivery of molecular hydrogen gas (dissolved in water) to mitigate radiation-induced cellular injury.

Oral intake of daily molecular hydrogen-supplemented water might be a prophylactic strategy to improve QOL of the (liver cancer ) patients receiving radiotherapy.

Although the mechanisms underlying the beneficial effects of molecular hydrogen-rich water during radiotherapy have not been clearly elucidated, drinking molecular hydrogen dissolved in water reduced dROM levels and maintained BAP levels in the serum, suggesting molecular hydrogen-rich water exhibits potent systemic antioxidant activity.

The safety of molecular hydrogen-rich water has also been determined as well as the optimal concentration of molecular hydrogen dissolved in water;

Daily intake of molecular hydrogen-rich water may be a promising approach for counteracting radiation-induced impairments to QOL.

This therapeutic use of molecular hydrogen is also supported by the work of Qian et al., who demonstrated that treating human lymphocyte AHH-1 cells with molecular hydrogen (saline) before irradiation significantly inhibited ionizing irradiation-induced apoptosis and increased cell viability in vitro.

They also showed that injection of molecular hydrogen-rich saline could protect the gastrointestinal endothelia from radiation-induced injury, decrease plasma malondialdehyde and intestinal 8-hydroxydeoxyguanosine levels, and increase plasma endogenous antioxidants in vivo [].

Conclusions

In conclusion, our study demonstrated that drinking molecular hydrogen-rich water improved QOL and reduced oxidative markers in patients receiving radiotherapy for liver tumors.

This novel approach of oral intake of molecular hydrogen-rich water may be applicable to a wide range of radiation-related adverse symptoms.

Drinking solubilized molecular hydrogen (dissolved in water) on a daily basis is beneficial and would be quite easy to administer without complicating or changing a patient’s lifestyle

Background

Radiotherapy is one of the major treatment options for malignant neoplasms. Nearly half of all newly diagnosed cancer patients will receive radiotherapy at some point during treatment and up to 25% may receive radiotherapy a second time []. Radiotherapy adversely affects the surrounding normal cells []. Acute radiation-associated side effects include fatigue, nausea, diarrhea, dry mouth, loss of appetite, hair loss, sore skin, and depression. Radiation increases the long-term risk of cancer, central nervous system disorders, cardiovascular disease, and cataracts. The likelihood of radiation-induced complications is related to the volume of the irradiated organ, the radiation dose delivered, the fractionation of the delivered dose, the delivery of radiation modifiers, and individual radiosensitivity []. Most radiation-induced symptoms are believed to be associated with increased oxidative stress and inflammation, due to the generation of reactive oxygen species (ROS) during radiotherapy, and may significantly affect the patient’s quality of life (QOL) [].

Molecular hydrogen (water) in the treatment of acute and chronic neurological conditions(Alzheimer’s, Parkinson’s,etc): mechanisms of protection and routes of administration

Molecular hydrogen (water) in the treatment of acute and chronic neurological conditions(i.e Alzheimer’s, Parkinson’s, etc. ): mechanisms of protection and routes of administration

 
 
We review the effects of molecular hydrogen water therapy in acute neuronal conditions and neurodegenerative diseases.
Molecular hydrogen water therapy /drinking water with dissolved molecular hydrogen may be useful for the prevention of neurodegenerative diseases and for reducing the symptoms of acute neuronal conditions.
 
Recently, the neuroprotective effects of treatment with molecular hydrogen (water) have been reported in both basic and clinical settings-as you will see below, we have examined the effects of molecular hydrogen H2  (water) treatment on acute central nervous system diseases and on chronic neurodegenerative diseases. We have also examined the various mechanism by which molecular hydrogen H2 exerts its neuroprotective effects .
Molecular hydrogen  H2 acts as a scavenger for OH and ONOO, affects neuroinflammation, preserves mitochondrial energy production, and possesses neuroprotective properties.
 
Unlike more conventional drugs, molecular hydrogen  H2 treatment, particularly the consumption of  molecular hydrogen  H2-rich water, has no known serious side effects and is effective for preventing the onset of neurodegenerative disease and aggravation of acute neuronal conditions – i.e.:
 

Molecular hydrogen water & Parkinson’s disease (PD)

Parkinson’s disease PD is a disorder that presents with extrapyramidal symptoms caused by the degeneration and loss of dopamine-producing cells in substantia nigra. Oxidative stress is known to be involved in the clinical condition of PD.() Moreover, the involvement of mitochondrial dysfunction in PD has been reported.()

The effects of molecular hydrogen  H2 on Parkinson’s disease PD have been reported in animal models of PD as well as in clinical studies.()

In 2009, Fujita et al.() and Fu et al.() reported that consuming  molecular hydrogen H2-rich water inhibits oxidative stress on the nigrostriatal pathway and prevents the loss of dopamine cells in a PD animal model. With the consumption of molecular hydrogen H2-rich-water-drinking, oxidative stress in the nigrostriatal pathway was inhibited and loss of dopamine cells was decreased. These results suggest that consuming molecular hydrogen H2-rich water could affect the onset of Parkinson’s Disease PD.

In recent years, the results of a clinical trial on the effects of consuming molecular hydrogen H2-rich water for Parkinson’s Disease PD have been reported.() A randomized double-blind study showed that consuming molecular hydrogen H2-rich water (1,000 ml/day) for 48 weeks significantly improved the total Unified Parkinson’s Disease Rating Scale (UPDRS) score of Parkinson’s disease PD patients treated with levodopa. A double-blind multi-center trial of molecular hydrogen H2 water is currently underway (Table 1).()

 

Molecular hydrogen water &  Alzheimer’s disease (AD)

Alzheimer Disease AD, an age-related neurodegenerative disease, is the most common cause of dementia.(,) Pathologically, it is characterized by the deposition of Aβ protein outside nerve cells and the accumulation of phosphorylated tau protein inside nerve cells. There is also a marked loss of nervous cells in the cerebral cortex.() In recent years, oxidative stress and neuroinflammation have been reported to be involved in Alzheimer’s disease AD.(,) To date, reports have centered on the involvement of oxidative stress in brain parenchyma.(,,)The accumulation of Aβ protein is strongly associated with the failure of Aβ clearance that is closely related to the pathogenesis of Alzheimer’s Disease AD.() It is known that low-density lipoprotein receptor-related protein 1 (LRP1) is involved in Aβ protein elimination. LRP dysfunction caused by oxidative stress and neuroinflammation is involved in the onset of Alzheimer’s Disease AD.() The regulation of oxidative stress and neuroinflammation may prevent the onset or progression of Alzheimer’s Disease AD. A number of reports have investigated the effects of molecular hydrogen H2 for the prevention of Alzheimer’s Disease AD onset.(,)

In a rat Alzheimer’s Disease AD model, it has been reported that the administration of molecular H2-rich saline (5 ml/kg, i.p., daily) inhibited oxidative stress, cytokine production, and nuclear factor-κB (NF-κB) production in the hippocampus and cerebral cortex, and improved impaired memory.(,)

It has  been reported that consuming molecular hydrogen H2-rich water inhibits age-related brain alterations and spatial memory decline.()

 

The therapeutic effect of molecular hydrogen H2-rich water following Traumatic brain injury (TBI) and in posttraumatic onset of Alzheimer’s disease (AD) was investigated by Dohi et al. in 2014,() who investigated whether the consumption of molecular hydrogen  H2-rich water 24 h prior to trauma can inhibit neuronal damage in a controlled cortical injury model using mice. The authors found that the expression of the phosphorylated tau proteins AT8 and Alz50 in the hippocampus and cortex was blocked in mice that consumed molecular hydrogen  H2-rich water. Moreover, the activity of astrocytes and microglia were inhibited in mice Traumatic Brain Injury model consuming molecular hydrogen H2-rich water. The expression of genes induced by Traumatic Brain Injury, particularly those that are involved in oxidation/carbohydrate metabolism, cytokine release, leukocyte or cell migration, cytokine transport, and adenosine triphosphate (ATP) and nucleotide binding, was inhibited by consuming molecular hydrogen  H2-rich water.

Dohi et al.() specifically reviewed the role of molecular hydrogen H2-rich water in neuroinflammation following brain trauma. The consumption of molecular hydrogen H2-rich water influenced the production of cytokines and chemokines in the damaged brain and inhibited the production of hypoxia inducible factor-1 (HIF-1), MMP-9, and cyclophilin A. However,molecular hydrogen  H2-rich water did not affect the production of amyloid precursor protein (APP), Aβ-40, or Aβ-42. They also investigated the relationship between molecular hydrogen H2 and ATP production and reported that molecular hydrogen H2 increased basal respiration, reserve capacity, and nonmitochondrial respiration but did not increase aerobic ATP production. It has thus been demonstrated that the inhibitory effects of molecular hydrogen H2 on nerve damage are not solely due to its simple function as a free radical scavenger (Fig. 1 and and22).

 
Molecular hydrogen is well characterized as a selective scavenger of hydroxyl radicals and peroxynitrite.

Oxidative stress caused by reactive oxygen species is considered a major mediator of tissue and cell injuries in various neuronal conditions, including neurological emergencies and neurodegenerative diseases.

 

Oxidative stress caused by reactive oxygen species (ROS) is a major mediator of tissue and cellular injuries in various neuronal conditions, including neurological emergencies and neurodegenerative diseases.()

Control of oxidative stress is a major therapeutic strategy for various neuronal conditions.(,,) There are many methods for controlling oxidative stress with the use of free radical scavengers being the most common approach.(,) Evidence from animal experiments support the notion that free radical scavengers and antioxidants dramatically reduce cerebral damage.() Edaravone (MCI-186), a novel free radical scavenger, was developed to prevent lipid peroxidation in pathological neurological conditions.(,)Edaravone is currently the only antioxidant drug approved for treating cerebral infarction that improves the functional outcome of ischemic stroke.() Brain hypothermia therapy (targeted temperature management) can also effectively control oxidative stress. Brain hypothermia therapy is effective in patients with various acute neuronal diseases.(,,)

In 2007, Ohsawa et al.() reported that molecular hydrogen (H2) can act as an antioxidant to prevent and treat middle cerebral artery occlusion–reperfusion injury in rats. This effect has been supported by additional reports. Recently, the beneficial effect of molecular H2 has been reported in many other organs, including the brain.() The first major therapeutic effect of molecular hydrogen H2 was that of an antioxidant, combining with hydroxyl ions to produce water.() Recently, other biological mechanisms of molecular hydrogen H2 (anti-inflammatory, anti-apoptosis, anti-cytokine, DNA expression, and energy metabolism) have been proposed (Fig. 1 and and22).()Therefore, the biology of molecular hydrogen H2 is not simple. In this review, we discuss the role of molecular H2 in various neuronal conditions.

Method and Route of Administration in Molecular hydrogen H2 Therapy

As a small (2 Da), uncharged molecule of hydrogen H2, would be expected to readily distribute throughout the body, including being able to easily penetrate cell membranes, However we are unable to determine the distribution of moleclar hydrogen H2 among organs and its concentrations in each organ and serum based on the administration methods and dosage. This problem was investigated in 2014.() A comparative review was conducted on the consumption of molecular hydrogen H2-rich water, i.p. or intravenous administration of molecular hydrogen  H2-rich saline, and inhalation of molecular hydrogen H2 gas. The results showed that the highest concentrations are reached 1 min after intravenous administration and 5 min after oral administration. The highest concentration was reached 30 min after the inhalation of molecular hydrogen H2 gas and was maintained for some time. Although molecular hydrogen H2 concentrations in the brain tend to be high after either intravenous administration or inhalation, no significant differences have been observed in comparison with the concentrations after the consumption of molecular hydrogen  H2-rich water and i.p. administration of molecular hydrogen H2-rich saline. Thus, although there have been variations based on the administration method, all methods have been found to result in the presence of molecular hydrogen H2 in the serum and brain tissue. Liu et al.() measured molecular hydrogen  H2 levels in the arteries, veins, and brain tissues after the inhalation of 2% molecular hydrogen H2 gas. They found that arterial molecular hydrogen H2 peaked at 30 min after administration, whereas venous and brain tissue molecular hydrogen H2 peaked at 45 min after administration. They reported that molecular hydrogen  H2 levels were similar in arteries and brain tissues.

This demonstrated that molecular hydrogen  H2 migrates to the brain tissue regardless of the method of administration(Thus, the studies below might as well have been performed using molecular hydrogen water instead of molecular hydrogen gas or molecular hydrogen saline).

These results suggest that the consumption of molecular hydrogen  H2-rich water prevents neurodegenerative disease and that molecular hydrogen H2-rich drinking water could be used to treat acute brain disorders (Fig. 1 and and22).

 
 
 
 

Molecular Hydrogen & Neurological Diseases

Molecular hydrogen & Ischemic brain injury

It has been reported that molecular hydrogen H2 prevents ischemic brain damage in animal experiments.(,) Ohsawa et al.() reported that inhalation of 2% molecular hydrogen H2 gas strongly suppressed infarct volume after middle cerebral artery ischemia–reperfusion in rats. In an electron spin resonance (ESR) study, they showed that molecular hydrogen  H2 had hydroxyl radical scavenging activity. Hydroxynonenal (HNE) and 8-hydroxy-2′-deoxyguanosine (8-OHdG) immunoreactivity was suppressed in the damaged brain after treatment with 2% molecular hydrogen H2. molecular hydrogen H2 inhalation reduced ischemic damage and hemorrhagic volume after transient middle crebral artery occlusion (MCAO) ischemia.() Free radical generation after ischemia induces matrix metalloproteinase (MMP) expression.(,) MMP-9 promotes hemorrhagic infarction by disrupting cerebral vessels.() molecular hydrogen H2 inhalation has been found to reduce MMP-9 expression in an MCAO rat model. molecular hydrogen H2 also has a neuroprotective effect against global ischemia. Ji et al.() reported that molecular hydrogen H2-rich saline injection [5 ml/kg intra-peritoneal (i.p.) administration] after global ischemia reduced neuronal cell death in hippocampal Cornet d’Ammon 1 (CA1) lesions in rats. Cerebral hypoxia–ischemia and neonatal asphyxia are major causes of brain damage in neonates. molecular hydrogen H2 gas inhalation and molecular hydrogen H2-rich saline injection provide early neuroprotection from neonatal neurological damage.() Nagatani et al.() reported that that an molecular hydrogen H2-enriched intravenous solution is safe for patients with acute cerebral infarction, including patients treated with tissue plasminogen activator (t-PA) therapy.

Metabolic syndrome is a strong risk factor of stroke. It has been reported that molecular hydrogen H2 therapy can improve metabolic syndrome in basic and clinical settings.() molecular hydrogen H2 therapy may reduce stroke in patients with metabolic syndrome involving diabetes mellitus.

Molecular hydrogen & Hemorrhagic stroke

Hemorrhagic stroke involving intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) is a critical neuronal condition, and the mortality rate of hemorrhagic stroke is still high.() Manaenko et al.() reported a neuroprotective effect of molecular hydrogen H2 gas inhalation using an experimental ICH animal model.molecular hydrogen H2 gas inhalation suppresses redox stress and blood brain barrier (BBB) disruption by reducing mast cell activation and degranulation. Brain edema and neurological deficits were also suppressed. In SAH, there are several studies demonstrating the neuroprotective effect of molecular hydrogen  H2 treatment.() A clinical trial has started in patients with SAH (Table 1).()

Table 1

Clinical trials of molecular hydrogen in central nervous system (CNS) diseases

Molecular hydrogen & Traumatic brain injury (TBI)

The efficacy of molecular hydrogen H2 for treating TBI has been investigated in several studies.(,,) Ji et al.() reported that in a rat TBI model,molecular hydrogen H2 gas inhalation has been found to protect BBB permeability and regulate posttraumatic brain edema, thereby inhibiting brain damage. molecular hydrogen H2 gas inhalation also inhibits the decrease in superoxide dismutase (SOD) activity and catalase (CAT) activity. These are antioxidant enzymes in posttraumatic brains that inhibit the production of malondialdehyde (MDA) and 8-iso-prostaglandin F2α (8-iso-PGF2α). Eckermann et al.() reported that in a surgical trauma mouse model involving right frontal lobectomy, molecular hydrogen H2 gas inhalation has been found to inhibit postoperative brain edema and improve the postoperative neurobehavioral score. The same report also showed that lipid peroxidation and the production of oxidative stress substances were not inhibited by molecular hydrogen  H2 gas inhalation.() 

Molecular Hydrogen & Spinal cord injury

Chen et al.() reviewed the effects of molecular hydrogen H2-rich saline administration (i.p.) in a rat traumatic spinal cord injury model. They found that posttraumatic neurological symptoms were improved by molecular hydrogen H2-rich saline treatment. Furthermore, molecular hydrogen H2-rich saline treatment has been found to reduce inflammatory cell infiltration, TdT-mediated dUTP nick and labeling (TUNEL)-positive cells, and hemorrhage. In addition, oxidative stress was inhibited and the expression of brain derived neurotrophic factor (BDNF) was increased.

The effects of molecular hydrogen H2 administration on spinal cord ischemia have also been reported.(,) Huang et al.()investigated the effects of molecular hydrogen H2 gas inhalation in a rabbit spinal cord ischemia–reperfusion model. They reviewed the effects of molecular hydrogen H2 inhalation with different concentrations (1, 2, and 4%) and reported that molecular hydrogen H2 gas inhalation at concentrations of 2% and 4% inhibited neuronal death. However, they did not observe significant differences between the two groups in terms of effects with 2% and 4% being equally effective.() It has been reported that the inhalation of 2% molecular hydrogen H2 gas inhibits apoptosis following spinal cord injury caused by ischemia–reperfusion. In addition, molecular hydrogen H2 gas inhalation regulates caspase-3 activity, the production of inflammatory cytokines, oxidative stress, and the decrease in endogenous antioxidant substances. Zhou et al.() also reported that molecular hydrogen H2-rich saline administration (i.p.) has beneficial effects on spinal cord ischemia–reperfusion injury in rabbits.

Other acute neurological conditions

In recent years, research has shown that there is a high incidence of comorbid central nervous system symptoms in sepsis cases.() Using a mice cecal ligation and puncture (CLP) model, Liu et al.() reported that molecular hydrogen H2 gas inhalation improves septic encephalopathy. They reported that 2%molecular hydrogen H2 gas inhalation inhibited post-CLP apoptosis, brain edema, BBB permeability, cytokine production, and oxidative stress in the CA1 hippocampus region as well as improves cognitive function. Nakano et al.() reported that maternal administration of  molecular hydrogen H2 has a suppressive effect on fetal brain injury caused by intrauterine inflammation with maternal intraperitoneal injection of lipopolysaccharide (LPS).

The treatment of carbon monoxide (CO) poisoning encephalopathy, which is a common gas poisoning, is yet to be established.(,) Sun et al.() and Shen et al.() investigated the effects of molecular hydrogen H2-rich saline. They reported that in a CO poisoning model, the administration of molecular hydrogen H2-rich saline decreased glial activation, cytokine production, oxidative stress, and caspase 3 and 9 production as well as inhibited nerve cell death.

It is known that oxidative stress causes nerve cell impairments.() The consumption of molecular hydrogen H2-rich water inhibits oxidative stress and thereby inhibits the onset of stress-induced brain damage.()

Hypoxic brain injury caused by asphyxiation, hypoxic ischemic encephalopathy, neonatal asphyxia, and other similar hypoxia-mediated event is a common clinical condition in medical emergencies. Molecular hydrogen H2 treatment has been found to inhibit cell death in an in vitro hypoxia/reoxygenation model using immortalized mouse hippocampal (HT-22) cells. Molecular hydrogen  H2 treatment increased phosphorylated Akt (p-Akt) and B-cell leukemia/lymphoma-2 (BCL-2), while it decreased Bax and cleaved caspase-3.() In recent years, it has been found that the microRNA-200 (miR-200) family regulates oxidative stress.() The inhibition of miR-200 suppresses H/R-induced cell death, reducing ROS production and MMP. Molecular hydrogen  H2 treatment suppressed H/R-induced expression of miR-200. In Japan, a double blind randomized controlled trial for post cardiac arrest syndrome has started from 2017 (Table 1).
