ABSTRACT

Aim      To study blood adipokines spectrum in people aged 25-44 years with early ischemic heart disease (IHD), including that associated with abdominal obesity (AO).Material and methods  A cross-sectional study was performed on a random sample of the population aged 25-44 years in Novosibirsk. 1457 subjects (653 men, 804 women) were evaluated. This study included 123 people divided into four study subgroups: subgroup 1, with IHD associated with AO (n=24); subgroup 2, with IHD and without AO (n=25); subgroup 3, without IHD and with AO (n=44); and subgroup 4, without either IHD or AO (n=30). Concentrations of serum adipokines were measured simultaneously by multiplex assay with a Luminex MAGPIX flow fluorometer and by immune enzyme assay with a MULTISCAN analyzer.Results Subjects with early IHD had lower blood concentrations of adipsin and visfatin than subjects without IHD. Subjects with early IHD associated with AO had higher blood concentrations of adipsin, plasminogen activator inhibitor-1, and leptin and lower concentrations of monocyte chemoattractant protein-1 (MCP-1) and visfatin compared to subjects with early IHD and without AO. The multivariate logistic regression analysis showed that lower blood concentrations of MCP-1 were associated with a likelihood of early IHD.Conclusion      In young people aged 25-44 years, lower blood concentrations of MCP-1 were associated with a likelihood of early IHD, including that associated with AO.

ABSTRACT

The article presents a variant of maturity onset diabetes of the young type 2, caused by a rare mutation in the GCK gene. Maturity onset diabetes of the young (MODY) is a hereditary form of diabetes with an autosomal dominant type of inheritance, an onset at a young age, and a primary defect in pancreatic ß-cell function. This type of diabetes is different from classical types of diabetes mellitus (DM1 and DM2) in its clinical course, treatment strategies, and prognosis. Clinical manifestations of MODY are heterogeneous and may vary even among members of the same family, i. e., carriers of identical mutations. This phenotypic variation is due to the interaction of mutations with different genetic backgrounds and the influence of environmental factors (e. g., lifestyle). Using next-generation sequencing technology, the c.580-1G>A substitution (IVS5 -1G>A, rs1554335421) located in an acceptor splice site of intron 5 of the GCK gene was found in a proband. The identified variant cosegregated with a pathological phenotype in the examined family members. The GCK gene encodes glucokinase (hexokinase 4), which catalyzes the first step in a large number of glucose metabolic pathways such as glycolysis. Mutations in this gene are the cause of MODY2. The illness is characterized by an insignificant increase in the fasting glucose level, is a well-controlled disease without medication, and has a low prevalence of micro- and macrovascular complications of diabetes. The presented case of MODY2 reveals the clinical significance of a mutation in the splice site of the GCK gene. When nonclassical diabetes mellitus is being diagnosed in young people and pregnant women, genetic testing is needed to verify the diagnosis and to select the optimal treatment method. Key words: human; maturity onset diabetes of the young; MODY2; glucokinase gene; next-generation sequencing; genetic analysis; bioinformatics.
