SS Hygiene Institute provided adequate funding for research on the treatment of mycobacterial infections, and two scientists who became famous in the subject were Dr. Waldemar Hoven (KL Buchenwald) and Dr. Kurt Heissmeyer (KL Neuengamme). They conducted researches not only on adult prisoners, but also on the Jewish children. Studies of tuberculosis were also conducted under the auspices of the German Medical Association by Dr. Rudolf Brachtel. In turn, Dr. Klaus Schilling dealt with the treatment and immunoprophylaxis of malaria. He tested such substances, as pyramidon, aspirin, quinine and atebrin on more than 1200 prisoners. These sulfonamide-derived drugs, were also studied by prof. Karl Gebhardt and Dr. Fritz Fischer. They assessed the efficacy of these drugs in the treatment of "dirty" wounds incurred by German soldiers. Dr. Heinrich Schutz, Karl Babor and Waldemar Wolter they were enthusiasts in so-called biochemical therapy, based on the use of substances of natural origin, such as salt. After termination of War, during the Nuremberg Trials, many of them evaded responsibility, they were running medical practices, some were publishing. However, despite those facts, trials of Nazi war criminals were not result less, they opened world's eyes for the necessity of clarifying rudiments of human subject research, they gave foundations to define records like The Convention for the Protection of Human Rights and Dignity of the Human Being with regard to the Application of Biology and Medicine or Good Clinical Practice.

The problem of immune-mediated diseases, such as inflammatory bowel disorders (IBDs), still remains a significant clinical and therapeutic problem. Therefore, the tendency to search for safer and more effective methods of reducing their incidence and increasing the efficiency of therapy of this group of diseases is understandable. Recently, attention has been drawn to the potential therapeutic influence of intestinal helminths on the inflammatory process induced by the immune response, as well as the observed significant potential of these organisms for modulating the host immune response, which is beneficial both for the dwelling parasite and the host with an IBD. It has been proven that the effects of certain intestinal helminths on the host immune system are complex and omni-directional. They involve the modulation of TLRs expression, causing proliferation and activation of TH2 lymphocytes, leading to proliferation of regulatory T cells (TREG), and production of immunomodulatory proteins, such as cystatins and glycoprotein ES-62. In the developing countries of Africa, South America and Asia, where the level of personal and environmental hygiene is relatively low, the incidence of autoimmune diseases is also significantly lower. Limited exposure to common bacterial and parasitic pathogens in populations of very highly developed countries has probably contributed to depletion of immunological memory and the development of hypersensitivity mechanisms. Thus, reasonable suggestions have been made that the host-parasite biocenotic relationship between humans and nematodes of the gastrointestinal tract can be considered as a mutualism, rather than a typical parasitism, and may in the future be used as an alternative therapeutic model for IBD patients. © 2014, Polish Physiological Society.

Biological medical products are drugs whose active components are produced only by living, genetically modified organisms or live cell cultures. Patents and exclusivity for most biopharmaceuticals has either expired or will expire soon, which enables biotechnological companies to introduce similar biological products. The problem of replacing a biological medicine with a biosimilar in the course of therapy remains open. In this statement, the Working Group of the Polish National Consultant in Gastroenterology, in the absence of data regarding bioequivalence in patients with inflammatory bowel disease, does not recommend switching from original biological medicine to its biosimilar analogue in the course of treatment in inflammatory disease patients; however, this may change after receiving the results of controlled studies regarding bioequivalence in this group.

Insulin resistance, oxidative stress, and an abnormal production of adipokines and cytokines are implicated in the pathogenesis of nonalcoholic steatohepatitis (NASH). Recently, we reported a significant improvement in plasma liver enzymes among patients with NASH treated with melatonin. In this study, we investigated the effect of melatonin, administered at a dose of 10 mg/day for 28 days to 16 patients with histologically proven NASH on insulin resistance (HOMA-IR), on the plasma levels of adiponectin, leptin, ghrelin, and resistin. Additionally, plasma levels of aminotransferases and gamma glutamyltranspeptidase as well as plasma concentrations of melatonin were evaluated. Median baseline values of HOMA-IR, leptin (ng/mL), and resistin (pg/mL) in patients with NASH were significantly higher in comparison with controls: 4.90 versus 1.60, 10.70 versus 4.30, and 152 versus 91, respectively. Median adiponectin level (μg/mL) was decreased in patients compared to controls: 6.40 versus 16.25; no significant difference in ghrelin levels between patients and controls was found. After melatonin treatment, the median value of HOMA-IR was significantly reduced by 60% as compared to baseline values, whereas adiponectin, leptin, and ghrelin plasma levels rose significantly by 119%, 33%, and 20%, respectively; the difference between pre-/posttreatment in plasma resistin levels was not significant. These findings make melatonin a suitable candidate for testing in patients with NASH in the large controlled clinical trials. © 2012 John Wiley & Sons A/S.

The present study represents the follow-up of our initial observations designed to investigate whether in patients with nonalcoholic steatohepatitis (NASH) the beneficial effect of 12-week course of melatonin (MT) on liver enzymes could be maintained with prolonged period of treatment and to analyze whether biochemical treatment responses could be sustainable after melatonin discontinuation. Forty two patients with histologically proven NASH (30 treated with melatonin 2×5 mg daily, 12 controls receiving placebo) enrolled to our previous 3-month study agreed to take part of subsequent 12 weeks treatment followed by 12-week follow-up period. Enrolled patients had biochemical determinations every six weeks during the melatonin treatment period and again after 12 weeks of follow-up. Significant reduction in median alanine aminotransferase (ALT) levels between baseline and week 18, week 24 and follow-up was observed in both MT-treated and control group: 43% and 31%, 42% and 33%, 32% and 31%. Aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase (GGT) levels decrease significantly only in MT-treated group. In MT-treated group mean percentage change in AST level below baseline at week 18, at week 24 and at follow-up was 45%, 33% (p<0.05) and 8% (ns), respectively. The evolution of GGT levels was as follows: the mean percentage reduction in GGT below baseline level at week 18, 24 and follow-up was: 48%, 52% and 38% (p<0.05), respectively. In both MT-treated and control group plasma cholesterol, triglicerydes and glucose concentrations as well as plasma alkaline phosphatase persisted within normal values during the prolonged study period. Plasma concentration of melatonin (pg/ml) in MT-treated group averaged 7.5±3.5 at baseline and increased to 52.5±17.5 at 24 th week. The results of our study demonstrating beneficial effect of melatonin on liver enzymes in patients with NASH would seem to encourage further controlled trials of melatonin given over a longer period of time with liver histology as end point.
