IL17A gene polymorphisms: relationship to predisposition for chronic viral hepatitis and progression to liver cirrhosis in kazakh population.

Introduction: This work is the first genetic association study of a potential relationship of single nucleotide polymorphisms rs8193036 and rs2275913 located in the IL17A promoter on chromosome 6p12 to chronic viral hepatitis and its progression in Kazakh population. Purpose: Evaluation of the effect of IL17A polymorphism on predisposition for chronic hepatitis B and C and its progression to liver cirrhosis. Materials and Methods: A total of 862 individuals were enrolled in the retrospective case-control association study. Among the participants, 100 patients had chronic hepatitis B and/or C and liver cirrhosis, and 341 patients had chronic viral hepatitis only. Four hundred twenty-one (421) healthy HBV- and HCV-negative donors without liver diseases were recruited as population control. single nucleotide polymorphisms rs8193036[T/C] and rs2275913[G/A] were genotyped by TaqMan assays using genomic DNA extracted from peripheral blood cells. Results. Minor allele frequencies of rs8193036[C] and rs2275913[A] in the groups of patients were very similar to those observed in the control population, 0.4 and 0.3, respectively. Multivariate logistic regression analysis revealed odds ratios close to 1.0 and confidence intervals overlapping with the value of 1.0 and statistical significance p > 0.4 for any groups under comparison in the multiplicative model of inheritance. conclusion: No significant association between two single nucleotide polymorphisms, rs8193036 and rs2275913 in the IL17A promoter, and susceptibility to chronic viral hepatitis C and/or B and disease progression to liver cirrhosis in Kazakh population were found.

Health-related quality of life in Kazakh heart failure patients evaluated by the Minnesota living with heart failure questionnaire and comparison with a published large international sample.

BACKGROUND: To assess health-related quality of life (HRQL) in Kazakh patients (n=285) treated in Cardiology Department of the Emergency Hospital of Semey during 2012 with acute myocardial infarction and to compare results with HRQL measured in 21 countries (n=3,847). METHODS: Telephone interviews survey was conducted in February 2014 with the Russian translation of Minnesota Living with Heart Failure Questionnaire (MLHFQ). Descriptive statistics were used to characterize the sample according to each single item of MLHFQ and grouping them in three subset concerning physical, emotional, and social environment dimensions of patients' life. The distribution of scores was evaluated in terms of floor and ceiling effects; Cronbach's alpha coefficient was calculated for the different dimensions to assess internal consistency. RESULTS: Mean age of sample is 60.8 years, most of patients are male (71.6%) and retired (43.5%). The total MLHFQ score was generally low at a moderate degree (mean 34.7, range 0-105). Physical dimension score (mean 14.92) shows mild to moderate impairment in HRQL and a better perception than the average of the control countries (14.9 vs 16.6); emotional status (mean 4.8) is moderately adequate and better than the controls (4.8 vs 7.2); social environment (9.82) showed significant impairment of HRQL and a worse evaluation (9.82 vs 7.8). CONCLUSIONS: Kazakh patients reported better emotional and physical HRQL as consequence of the social structure where family environment promotes emotional support and improves self-care, social environment affects the total MLHFQ score that is low and related to the requested availability of free medicines.
