Backgrounds: Maturity-onset diabetes of the young (MODY) is a cluster of early-onset, monogenic disorders which is inherited in autosomal dominant form. It is mainly caused by genetic defects in beta-cell, which results in beta-cell dysfunction. Till now, 14 MODY types specified by mutation in respective 14 genes with their etiologies are known. Among them, glucokinase (GCK) gene encodes glucokinase enzyme which plays a crucial role in the regulation of insuli...

Introduction: The association between ATD and AIG is very poorly characterized in pediatric age. We review the prevalence of the anti-gastric parietal cells antibodies (APCA) in young patients with ATD and we evaluated the development of AIG during follow-up, in order to define the usefulness of these markers for AIG screening in these patients.Patients and Methods: We evaluated 220 children and adolescents (11.28 ±...

Background: The non-physiological ways and supraphysiological doses of insulin required for good glycemic control in patients with type 1 diabetes right from onset exposes them to effects of hyperinsulinism. In addition insulin resistance may be seen because of glucose toxicity and abnormal fat mass gain during puberty Insulin acts synergistically with luetinizing hormone to facilitate androgen production by theca.Objective and hypotheses: To investigate...

Background: Few studies have addressed the question of psychological impact and long term outcomes in MRKH patients.Objective and hypotheses: Our national multi-centric study aimed to assess MRKH patients’ experience concerning diagnostic announcement, treatment perception, impact on psychic functioning, socio-professional integration, affective and sexual life and quality of life.Method: First 40 MRKH patients aged 19–34...

Background and hypotheses: Urinary C-peptide creatinine ratio (UCPCR) is a new, non-invasive, economical test recommended in differential diagnoses of maturity-onset diabetes of the young (MODY). There are a few studies on this topic. UCPCR values were determined as >0.2 and >0.7 nmol/mmol with a high specificity and sensitivity in differential diagnosis in the previous two studies, the values were evaluated in only three MODY types (HNF1A/HNF4A/GCK-MODY). We investiga...

Background: FOXE1 gene variants containing alterations in the alanine tract length may confer susceptibility to primary ovarian insufficiency (POI). BMP15 gene variants have also been related to POI.Objective and hypotheses: To evaluate the contribution of FOXE1 and BMP15 variants in the pathogenesis of POI and to investigate the hypothesis of digenic inheritance in this disorder.Method: FOXE1 and BMP...

Background: The success of highly active antiretroviral therapy (HAART) has dramatically increased life expectancy for human immunodeficiency virus (HIV)-positive patients, revealing a range of chronic problems associated with HIV. Among others, low bone mineral density (BMD) has been described in HIV-infected youths. Little is currently known about the changes of BMD over time in these patients.Objective and hypotheses: The aim of the study was to asses...

Background: Among the currently known variants of maturity-onset diabetes of the young (MODY) subtypes 1–3 are the most prevalent, while their relative frequencies vary in different populations. Other types of MODY are more rare, although the studies addressing their prevalences are limited. Recent implementation of next-generation sequencing (NGS) enables simultaneos analysis of multiple candidate genes making it an attracive approach in various monogenic disorders, incl...

Background: Autoimmune thyroid disease (AITD), including autoimmune thyroiditis (AT) and Graves’ disease (GD), is a complex autoimmune disease with a strong genetic component. The cytotoxic product of T-lymphocyte antigen-4 (CTLA4) gene, encoding a negative regulator of the T-lymphocyte immune response, was shown to be associated to AITD.Objective and hypotheses: To investigate the association of A49G and C60T polymorphisms of CTLA4 gene in populati...

Background: We are not aware of other longitudinal cohort studies of boys with prepubertal assessment of exposure to endocrine-disrupting chemicals (EDCs) and annual long term follow-up of growth and puberty to evaluate semen quality.Objective: To describe semen quality and explore associations of prepubertal serum concentrations of organochlorine compounds and pubertal measures with semen parameters in an ongoing longitudinal cohort study of Russian boy...
