Abstract
Blood cancers are a group of diseases with thus far frequently poor prognosis. Although many new drugs, including target therapies, have been developed in recent years, there is still a need to expand our therapeutic armamentarium to better deal with these diseases. Integrative hematology was conceived as a discipline that enriches the patient's therapeutic possibilities with the use of supplements, vitamins and a nutritional approach aiming at improving the response to therapies and the clinical outcome. We will analyze the substances that have proved most useful in preclinical and clinical studies in some of the most frequent blood diseases or in those where these studies are more numerous; the importance of the nutritional approach and the role of the intestinal microbiota will also be emphasized.

Christophersen OA. Radiation protection following nuclear power accidents: a survey of putative mechanisms involved in the radioprotective actions of taurine during and after radiation exposure. MICROBIAL ECOLOGY IN HEALTH AND DISEASE 2012; 23:14787. [PMID: 23990836 PMCID: PMC3747764 DOI: 10.3402/mehd.v23i0.14787] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/18/2011] [Accepted: 11/18/2011] [Indexed: 12/28/2022]
Abstract
There are several animal experiments showing that high doses of ionizing radiation lead to strongly enhanced leakage of taurine from damaged cells into the extracellular fluid, followed by enhanced urinary excretion. This radiation-induced taurine depletion can itself have various harmful effects (as will also be the case when taurine depletion is due to other causes, such as alcohol abuse or cancer therapy with cytotoxic drugs), but taurine supplementation has been shown to have radioprotective effects apparently going beyond what might be expected just as a consequence of correcting the harmful consequences of taurine deficiency per se. The mechanisms accounting for the radioprotective effects of taurine are, however, very incompletely understood. In this article an attempt is made to survey various mechanisms that potentially might be involved as parts of the explanation for the overall beneficial effect of high levels of taurine that has been found in experiments with animals or isolated cells exposed to high doses of ionizing radiation. It is proposed that taurine may have radioprotective effects by a combination of several mechanisms: (1) during the exposure to ionizing radiation by functioning as an antioxidant, but perhaps more because it counteracts the prooxidant catalytic effect of iron rather than functioning as an important scavenger of harmful molecules itself, (2) after the ionizing radiation exposure by helping to reduce the intensity of the post-traumatic inflammatory response, and thus reducing the extent of tissue damage that develops because of severe inflammation rather than as a direct effect of the ionizing radiation per se, (3) by functioning as a growth factor helping to enhance the growth rate of leukocytes and leukocyte progenitor cells and perhaps also of other rapidly proliferating cell types, such as enterocyte progenitor cells, which may be important for immunological recovery and perhaps also for rapid repair of various damaged tissues, especially in the intestines, and (4) by functioning as an antifibrogenic agent. A detailed discussion is given of possible mechanisms involved both in the antioxidant effects of taurine, in its anti-inflammatory effects and in its role as a growth factor for leukocytes and nerve cells, which might be closely related to its role as an osmolyte important for cellular volume regulation because of the close connection between cell volume regulation and the regulation of protein synthesis as well as cellular protein degradation. While taurine supplementation alone would be expected to exert a therapeutic effect far better than negligible in patients that have been exposed to high doses of ionizing radiation, it may on theoretical grounds be expected that much better results may be obtained by using taurine as part of a multifactorial treatment strategy, where it may interact synergistically with several other nutrients, hormones or other drugs for optimizing antioxidant protection and minimizing harmful posttraumatic inflammatory reactions, while using other nutrients to optimize DNA and tissue repair processes, and using a combination of good diet, immunostimulatory hormones and perhaps other nontoxic immunostimulants (such as beta-glucans) for optimizing the recovery of antiviral and antibacterial immune functions. Similar multifactorial treatment strategies may presumably be helpful in several other disease situations (including severe infectious diseases and severe asthma) as well as for treatment of acute intoxications or acute injuries (both mechanical ones and severe burns) where severely enhanced oxidative and/or nitrative stress and/or too much secretion of vasodilatory neuropeptides from C-fibres are important parts of the pathogenetic mechanisms that may lead to the death of the patient. Some case histories (with discussion of some of those mechanisms that may have been responsible for the observed therapeutic outcome) are given for illustration of the likely validity of these concepts and their relevance both for treatment of severe infections and non-infectious inflammatory diseases such as asthma and rheumatoid arthritis.

Abstract
Low-grade non-Hodgkin lymphomas (NHLs) at advanced stage are still incurable, and treatment may include chemotherapy with a single drug or a combination of different drugs. With a combination of cyclophosphamide, somatostatin, bromocriptin, retinoids, melatonin, and adrenocorticotropic hormone, we already reported 100% of global response (50% complete response and 50% partial response) in 12 patients with low-grade NHL at advanced stage: 4 previously untreated patients and 8 with relapse of disease after single or combined chemotherapy and therapy free time >or=6 months. This provided the rationale to treat a patient affected by low-grade NHL stage 4, with cyclophosphamide, somatostatin, bromocriptin, retinoids, and melatonin (adrenocorticotropic hormone was not administered for high blood pressure). The patient was treated for at least 2 months. After this period, if he had stable or responding disease, he received an additional 3 months of treatment, and if he was stable or responding after 5 months he was treated for 3 months and more. After 2 months the patient had a partial response, and after 5 months he achieved a complete response. Today, 18 months after the beginning of treatment, the patient is in complete remission. Treatment had very good tolerance, and the patient carried on at home doing his normal activities.

Abstract
PURPOSE Somatostatin, prolactin, retinoids, melatonin and ACTH have been shown to influence the lymphatic growth, and the action of the cyclophosphamide in lymphoproliferative disorders is well known. This provided the rationale to conduct, in patients with low-grade non-Hodgkin's lymphomas (NHL), a phase II trial of a combined association of cyclophosphamide, somatostatin, bromocriptin, retinoids, melatonin and ACTH. PATIENTS AND METHODS Twenty patients with a diagnosis of low-grade NHL, stage III or IV, were included in this study. Patients received for one month the following treatment: cyclophosphamide, somatostatin, bromocriptin, retinoids, melatonin, and ACTH. The therapy was continued for two additional months in patients with stable or responding disease. After three months, the responding patients continued the therapy for three months and more. RESULTS Twenty patients were assessable for toxicity and response; 70% (14 of 20 patients; 95% confidence interval [CI], 50% to 90%) had a partial response; 20% (4 of 20) had stable disease, and 10% (2 of 20) progressed on therapy. Going on with the treatment, none of the 14 patients with partial response had a disease progression (average follow-up time of 21 months, range, 7 to 25), and 50% of these patients had a complete response; among 4 patients with stable disease, 25% (1 of 4) had a partial response and 75% (3 of 4) progressed on therapy (mean time to progression [TTP] 14.3 months, range, 7 to 21). The toxicity was very mild, the most common side effects being drowsiness, diarrhea and hyperglycemia. CONCLUSIONS The association of cyclophosphamide, somatostatin, bromocriptin, retinoids, melatonin, and ACTH is well tolerated and effective in treatment of low-grade NHL at advanced stage.

Abstract
In this article we review the state of the art on the role of the pineal gland and melatonin in mammary cancer tumorigenesis in vivo as well as in vitro. The former hypothesis of a possible role of the pineal gland in mammary cancer development was based on the evidence that the pineal, via its main secretory product, melatonin, downregulates some of the pituitary and gonadal hormones which control mammary gland development and are also responsible for the growth of hormone-dependent mammary tumors. Furthermore, melatonin could act directly on tumoral cells, thereby influencing their proliferative rate. Other possible origins of melatonin's antitumoral actions could be found in its antioxidant or immunoenhancing properties. The working hypotheses of most experiments were that the activation of the pineal gland, or the administration of melatonin, should give rise to antitumoral behavior; conversely, suppression of the pineal gland or melatonin deficits should stimulate mammary tumorigenesis. From in vivo studies on animal models of tumorigenesis, the general conclusion is that experimental manipulations activating the pineal gland, or the administration of melatonin, enlarge the latency and reduce the incidence and growth rate of chemically induced mammary tumors, while pinealectomy usually has the opposite effects. The direct actions of melatonin on mammary tumors have been suggested because of its ability to inhibit, at physiological doses (1 nM), the in vitro proliferation and invasiveness of MCF-7 human breast cancer cells. The fact that most studies have been performed on two models, chemically induced mammary adenocarcinoma in rats (in vivo studies) and the cell tumor line MCF-7 (in vitro studies), makes the generalization of the results somewhat difficult. However, the characteristics of these actions, comprising different aspects of tumor biology such as initiation, proliferation, and metastasis, as well as the doses (physiological range) at which the effect is accomplished, give special value to these findings. On the strength of these data, the small number of clinical studies focusing on the possible therapeutic value of melatonin on breast cancer is surprising.

Abstract
The pineal indole amine melatonin has been shown to have oncostatic properties in a wide variety of neoplasms. Melatonin levels start to diminish before the onset of puberty and continue to decline during puberty. There appears to be a relationship between the rate of bone growth and the incidence of osteosarcoma (which was found to be highest in the long bones of the leg in the 10-14-year age group). It is hypothesized that the simultaneous decrease in melatonin levels (with diminishing oncostatic protection), concurrent with the exponential increase in bone growth during puberty (i.e. increased rate of cell proliferation), could be a factor in the typical age distribution of osteosarcoma. Melatonin is of value in combined chemotherapy, because it is non-toxic and can augment the anti-cancer action and decrease the side-effects of many other chemotherapeutic drugs. It is hoped that melatonin, as an adjunct to the routine chemotherapy of osteosarcoma, will help to improve the prognosis of this too often fatal disease.

Abstract
The validity of melatonin as a prominent, naturally occurring oncostatic agent is examined in terms of its putative oncostatic mechanism of action, the correlation between melatonin levels and neoplastic activity, and the outcome of therapeutically administered melatonin in clinical trials. Melatonin's mechanism of action is summarized in a brief analysis of its actions at the cellular level, its antioxidative functions, and its indirect immunostimulatory effects. The difficulties of interpreting melatonin levels as a diagnostic or prognostic aid in cancer is illustrated by referral to breast cancer, the most frequently studied neoplasm in trials regarding melatonin. Trials in which melatonin was used therapeutically are reviewed, i.e., early studies using melatonin alone, trials of melatonin in combination with interleukin-2, and controlled studies comparing routine therapy to therapy in combination with melatonin. A table compiling the studies in which melatonin was used in the treatment of cancer in humans is presented according to the type of neoplasm. Melatonin's suitability in combination chemotherapy, where it augments the anticancer effect of other chemotherapeutic drugs while decreasing some of the toxic side effects, is described. Based on the evidence derived from melatonin's antiproliferative, antioxidative, and immunostimulatory mechanisms of action, from its abnormal levels in cancer patients and from clinical trials in which melatonin was administered, it is concluded that melatonin could indeed be considered a physiological anticancer substance. Further well-controlled trials should, however, be performed in order to find the link between its observed effects and the underlying mechanisms of action and to define its significance as a therapeutic oncostatic agent.

Abstract
Experimental data have suggested that the pineal hormone melatonin (MLT) may counteract chemotherapy-induced myelosuppression and immunosuppression. In addition, MLT has been shown to inhibit the production of free radicals, which play a part in mediating the toxicity of chemotherapy. A study was therefore performed in an attempt to evaluate the influence of MLT on chemotherapy toxicity. The study involved 80 patients with metastatic solid tumors who were in poor clinical condition (lung cancer: 35; breast cancer: 31; gastrointestinal tract tumors: 14). Lung cancer patients were treated with cisplatin and etoposide, breast cancer patients with mitoxantrone, and gastrointestinal tract tumor patients with 5-fluorouracil plus folates. Patients were randomised to receive chemotherapy alone or chemotherapy plus MLT (20 mg/day p.o. in the evening). Thrombocytopenia was significantly less frequent in patients concomitantly treated with MLT. Malaise and asthenia were also significantly less frequent in patients receiving MLT. Finally, stomatitis and neuropathy were less frequent in the MLT group, albeit without statistically significant differences. Alopecia and vomiting were not influenced by MLT. This pilot study seems to suggest that the concomitant administration of the pineal hormone MLT during chemotherapy may prevent some chemotherapy-induced side-effects, particularly myelosuppression and neuropathy. Evaluation of the impact of MLT on chemotherapy efficacy will be the aim of future clinical investigations.

Abstract
A role for melatonin in humans is becoming evident in an increasing number of clinical situations. Marked variations in the magnitude of the nocturnal melatonin peak are observed throughout the human lifespan. The highest levels occur in children and then fall during puberty and further during adulthood. A negative correlation between circulating melatonin and sex steroids has been observed in a number of instances, and appears to be independent of concomitant gonadotrophins. No clear melatonin pattern has been observed in pituitary tumors, but in large lesions that involve the hypothalamus, a reduced nocturnal rise has been reported. Reported effects of exogenously administered melatonin are variable, probably reflecting differences in dose and timing; a slight stimulation of prolactin, as well as a partial inhibition of gonadotrophins, has been reported, which explains its utility as an oral contraceptive, associated with a progestogen. A potential clinical use of melatonin as an oncostatic drug still awaits confirmation, although experimental data firmly support this possibility. The indole has also been used to hasten entrainment of subjects travelling across various time zones, and has been found to be specially useful in eastward travel. Finally, changes in the normal melatonin circadian pattern have been reported in psychiatric diseases and in sudden infant death syndrome.

Abstract
In the past several years, interest in the immunophysiological role of the pineal gland and melatonin has grown to the extent that now their immunoregulatory role is widely recognized. Melatonin has immunoenhancing properties and it is able to counteract the immunodepression induced by acute stress, drug treatment (i.e., anticancer drugs), and viral infections. Here we review the therapeutic efficacy of melatonin alone or in combination with interleukin-2 (IL-2) in cancer patients who did not respond to standard anticancer chemotherapies and/or refused any aggressive treatment. In this review, we summarize a series of reports from 1986 through 1994 in which patients affected by metastatic solid tumors, metastatic non-small-cell lung cancer, advanced solid neoplasms, myelodysplastic syndrome, hepatocellular carcinoma, and advanced endocrine tumors were studied. The conclusion drawn from these studies is that melatonin protects against IL-2 and synergizes with the IL-2 anticancer action. This combined strategy represents a well tolerated intervention to control tumor growth. In most cases performance status and quality of life seem improved.
