ABSTRACT

Currently, there is an increase in the resistance of microorganisms to the available arsenal of antimicrobial drugs, which makes it necessary to maintain and stimulate the body's own immune-protective properties. The main extraskeletal effect of vitamin D activity is associated with the homeostasis of the immune system. The role of vitamin D in reducing the risk of infection with infectious agents has been studied for a long time. Literature search on the effective use of vitamin D for immunoprophylaxis was carried out in Scopus, Web of Science, PubMed, clinicaltrials.gov databases over the past 10 years for related keywords: vitamin D, immunoprophylaxis. Vitamin D stimulates the synthesis of antimicrobial peptides, cathelicidins and defensins, which exhibit broad-spectrum activity against viruses, bacteria and fungal infections; reduces the concentration of pro-inflammatory cytokines; increases the concentration of anti-inflammatory cytokines. Vitamin D is also involved in cell differentiation, maturation and proliferation of immune cells. The article presents the literature review in order to justify additional intake of vitamin D in case of diagnosis of its deficiency and insufficiency for the purpose of immunoprophylaxis in children and adults, especially in risk groups (elderly age, pregnant women, patients with chronic diseases of respiratory, endocrine and urinary systems, gastrointestinal tract, and infectious diseases). Inclusion of vitamin D in the diet as a dietary supplement, as well as fortification of products with it, can be an effective measure to reduce the risk of both morbidity and mortality, especially during the period of quarantine measures.

ABSTRACT

Ketogenic diet (KD) is a high-fat, adequate-protein, and low-carbohydrate diet that leads to nutritional ketosis, long known for antiepileptic effects and has been used therapeutically to treat refractory epilepsy. This review attempts to summarize the evidence and clinical application of KD in diabetes, obesity, and other endocrine disorders. KD is usually animal protein based. An empiric vegetarian Indian variant of KD has been provided keeping in mind the Indian food habits. KD has beneficial effects on cardiac ischemic preconditioning, improves oxygenation in patients with respiratory failure, improves glycemic control in diabetics, is associated with significant weight loss, and has a beneficial impact on polycystic ovarian syndrome. Multivitamin supplementations are recommended with KD. Recently, ketones are being proposed as super-metabolic fuel; and KD is currently regarded as apt dietary therapy for "diabesity."

ABSTRACT

INTRODUCTION: Patients often use dietary supplements in addition to the therapies prescribed by their physicians. This self medication is often not listed in the drug history. We supposed that people, who are more afraid of co-morbidities or diabetes late complications and who exhibit a higher fear of the potential side effects of prescribed drugs, are more inclined to use dietary supplements. PATIENTS AND METHODS: We checked the use of dietary supplements with a standardised questionnaire in patients treated in a centre for endocrinology and metabolic diseases. Demographic and clinical data were taken from the electronic health record EMIL®. RESULTS: A total of 428 patients (51.4% women), mean age 58.3 years, completed the standardised questionnaire. Supplements were used by 41%: Mineral nutrients 60.2%, vitamins 56.8%, "other supplements" (e. g. omega-3-fatty acids, antidiabetic agents) 43.1% and medical herbs 35.1%. The users of supplements were predominantly women (p<0.001), non-smokers (p=0.004), persons with frequent medical appointments (p=0.014) and with a negative attitude towards the effectiveness of the physician prescribed medication (p=0.012). Patients with diabetes do not use supplements more often than patients without. The use of dietary supplements was not associated with patients' fear to develop co-morbidities of existing diseases (p=0.132) or a higher fear of side effects of prescribed drugs (p=0.099). CONCLUSIONS: Nearly half of the patients in a centre for endocrinology and metabolic diseases use self medications with dietary supplements. There is no association between the fear of co-morbidities or side effects of physicians prescribed drugs and a self medication with dietary supplements.

ABSTRACT

Isoflavones, a group of phytoestrogens, are selective oestrogen receptor (ER) modulators. They may positively impact endocrine-related conditions but the current evidence is sparse. Equol, a non-steroidal oestrogen, is produced by the metabolism of the isoflavone daidzein by intestinal bacteria. In Western countries, 30-50% of individuals metabolize daidzein into equol and are known as equol producers. Equol production may be the source of benefit from isoflavones in endocrine disease.
