Summary Diabetes mellitus is a heterogeneous group of disorders in which particular disease phenotypes can be characterized by a specific etiology and/or pathogenesis of the disease, but in many cases its classification is greatly impeded due to significant phenotype overlapping. Diabetes is a wordwide epidemic with significant health and economic consequences. The frequency of type 2 diabetes (T2D) is much higher than type 1 diabetes (T1D). In adults, around 285 million people suffer from T2DM with a projected rise to 438 million in the next 20 years. A variety of pharmacological treatments exist for patients with T2D, in addition to dietary and physical activity. Pharmacologically, diabetes is treated with nine major classes of approved drugs, including insulin and its analogues, sulfonylureas, biguanides, thiazolidinediones (TZDs), meglitinides, a-glucosidase inhibitors, amylin analogues, incretin hormone mimetics, and dipeptidyl peptidase 4 (DPP4) inhibitors. Treatment strategy for T2D is based mostly on oral hypoglycemic drug (OHD) efficacy assessed usually by HbA1c and/or fasting plasma glucose. The patients are often treated with more than one OHD in combination with the purpose to receive more effective treatment. Characterization of drug response is expected to substantially increase the ability to provide patients with the most effective treatment strategy. If pharmacogenetic testing for diabetes drugs could be used to predict treatment outcome, appropriate measures could be taken to treat T2D more efficiently. To date, major pharmacogenetic studies have focused on response to sulfonylureas, biguanides, and TZDs, the most used OHD. A comprehensive review of the pharmacogenetic studies of specific OHD is presented in this article. Understanding the pharmacogenetics of these drugs will provide critical baseline information for the development and implementation of a genetic screening program into therapeutic decision making, enabling a personalized medicine approach for T2D patients.

The seasonal variation of serum 25-hydroxy vitamin D3 and 1,25-dihydroxyvitamin D has been investigated. Blood was taken from 27 healthy volunteers, aged 21–44 years old at 3 monthly intervals over a period of 1 year. A scrolling monthly programme with 12 quarterly (3 month) time periods was developed. A summer associated increase in 25-hydroxy vitamin D3 was significantly correlated with but lagged behind by 2 months, the increase in recorded sunlight hours. However, four individuals showed no seasonal rise but maintained constant concentrations throughout the year within the established reference range. Serum 1,25-dihydroxy vitamin D showed marked intra-individual variability with no seasonal pattern although the highest concentration (180 pmol/L) was observed in the winter and no concentration greater than 108 pmol/L in the summer.

This review is addressing an urgent problem of diagnosis and treatment strategy of polycystic ovary syndrome in adolescent girls. We analysed data from modern literary publications on the epidemiology and classification of the disease, as well as the adaptation of general principles for the management of young female patients tailored to their age peculiarities. The effective treatment strategies for adolescent girls with PCOS depending on its type are presented. Today there are several contradictions associated with both the diagnosis and treatment of the disease in the medical community. Thus, the use of the well-known Rotterdam criteria makes it difficult to diagnose PCOS in adolescent girls, since the criteria do not take into account characteristic changes that occur during puberty. Such manifestations as acne, hirsutism, menstrual irregularities, high androgen levels and morphology of polycystic ovaries on pelvic ultrasound imaging should be assessed with due account for age, puberty, hormonal balance with an assessment of the ratio of LH (luteinizing hormone)/FSH (follicle-stimulating hormone) and Free Androgen Index. There is no consensus in the medical community regarding the treatment strategy for PCOS. International communities have identified two main goals in the management of patients: normalization of menstrual function and improvement of the patients’ quality of life by preventing clinical symptoms of hyperandrogenism, and metabolic disorders of hyperplastic processes in target organs.Our analysis of objective scientific data showed that modern monophasic combined oral contraceptives (COCs) supplemented by of a folate component should be used to treat young female patients with PCOS, hyperandrogenism and psychosomatic disorders.

Children with autism spectrum disorder have been found to have lower levels of vitamin D than their peers. Our case report supports the hypothesis that vitamin D may be an effective treatment for developmental delay in autism. In addition, we review the literature surrounding vitamin D deficiency as a potential cause of autism spectrum disorder and the role that vitamin D may play in treatment.

AimsTo compare depressive symptoms in participants with low and high serum 25-hydroxyvitamin D (25(OH)D) levels and to examine whether supplementation with vitamin D3 would improve symptoms in those with low serum 25(OH)D levels.MethodParticipants with low 25(OH)D levels were randomised to either placebo or 40 000 IU vitamin D3 per week for 6 months. Individuals with high serum 25(OH)D levels were used as nested controls. Depressive symptoms were evaluated with the Beck Depression Inventory, Hospital Anxiety and Depression Scale, Seasonal Pattern Assessment Scale and Montgomery-Åsberg Depression Rating Scale. The study was registered at ClinicalTrials.gov (NCT00960232).ResultsParticipants with low 25(OH)D levels (n=230) at baseline were more depressed (P<0.05) than participants with high 25(OH)D levels (n=114). In the intervention study no significant effect of high-dose vitamin D was found on depressive symptom scores when compared with placebo.ConclusionsLow levels of serum 25(OH)D are associated with depressive symptoms, but no effect was found with vitamin D supplementation.
