Background: Post-COVID-19 condition (long COVID-19, post-acute COVID-19, long-term effects of COVID-19) is an emerging health problem in people recovering from COVID-19 infection within the past 4-6 months. Patients with type 2 diabetes (T2D) are in the risk group for a more severe course of COVID-19 and the development of its complications. Aim: to define the prevalence and prediction of post-COVID-syndrome development in patients with T2D according to ...

Background: Insulin gene (INS) is known to be responsible for production of insulin by the pancreatic β-cells. It includes variable number of tandem repeats (VNTR) of oligonucleotide consequence (ACAGGGGT (G/C) (T/C) GGGG) in the promoter region (Bell et al, 1981,1982); being the gene involved in the susceptibility to various pathologies. The allele-specific PCR allows direct diagnosis of some genetically determined disorders is rather simple and precise. However, by toda...

Background: International consensus supports interval biochemical and imaging surveillance for all asymptomatic carriers of succinate dehydrogenase (SDHx) gene mutations and patients with a history of SDH deficient tumours. There is growing awareness that the life time penetrance of the SDHx genes is much lower than that originally estimated and that long term radiological surveillance carries a significant risk including ionizing radiation exposure and incidental findings. Th...

The exact pathogenesis and causative interaction between T- and B-lymphocytes in peripheral blood and thyroid gland immune-mediated mechanisms of Graves disease (GD) are still unknown. Detailed knowledge about lymphocyte subpopulation composition in peripheral blood and thyroid tissue will therefore enhance our understanding of the pathogenesis of GD and might support the development of new immunomodulatory treatment approaches. Aim: to study the relationship between helper- (...

Introduction: Hypertension (HTN) is a major cardiovascular (CV) risk factor and independent predictor of the increased mortality in patients with acromegaly. Surgical cure of acromegaly is associated with improvement in blood pressure (BP) levels, however little is known on the effect of pegvisomant (PEGV) treatment on HTN.Methods/design: ACROSTUDY is an open-label, international, prospective, non-interventional study monitoring the long-term safety of P...

: A large number of studies are now focused on the causes of male infertility. Among these are epigenetic modifications, which are important contributors to reproductive pathology in the male by providing dynamic changes of the phenotype according to the environmental and metabolic factors. The most known epigenetic modification is DNA methylation and alterations in this pattern in several genes could induce male infertility. Alterations in DNA methylation patterns in several ...

The CDX2 VDR polymorphism (rs11568820) is located in the promoter region of exon 1 in the 5′-untranslated region of the VDR gene.Objective: The current investigation examines the association between CDX2 VDR polymorphism and male infertility.Subjects and methods: The study was conducted on 69 infertile men, aged between 20 and 50 years, divided into three groups, based on spermatic parameters: group with azoospermia (19 subje...

Background: Obesity is a major risk factor to develop heart failure, in part due to possible lipotoxic effects of increased intramyocardial (MYCL) and/or pericardial (PERI) lipid accumulation. Recent evidence suggests that MYCL is highly dynamic and might rather be a surrogate marker for disturbed energy metabolism than the underlying cause of cardiac dysfunction. On the other hand, PERI might contribute directly by mechanic and paracrine effects. Therefore, we hypothesized th...

Introduction: Legg calvé perthes (LCP) is a disease characterized by idiopathic avascular necrosis of the proximal femoral epiphysis caused by decreased blood flow. More frequently in boys between 2 and 12 years of age. LCPD is of unknown etiology.We present two male patients of LCP associated with pituitary disorders.Case presentation: Case 1: g.i.c., 8 years 8 month, was first addressed to the endocrinology department for in...

Background: Normal thyroid function is necessary for the optimal effect of recombinant growth hormone (rhGH) on growth rate. GH therapy in children with GH deficiency (GHD) has yielded conflicting results concerning its impact on thyroid function. Data about patients developing subclinical hypothyroidism (SH) are scanty, but it is thought to be associated with impairment of metabolic profile and lower growth response.Objective: To evaluate the effect of ...
