ASSOCIATION ANALYSIS OF PIOGLITAZONE EFFECTIVENESS IN TREATMENT OF NAFLD PATIENTS WITH OBESITY AND PPARG RS1801282 (PRO12ALA) GENOTYPE

The aim: To study the association between the effectiveness of treatment with pioglitazone non-alcoholic fatty liver disease (NAFLD) in patients with obesity and PPARG rs1801282 (Pro12Ala)-polymorphism in Ukrainians. Materials and methods: 123 patients with NAFLD in combination with obesity 1, 2, 3 classes were included in comprehensive weight loss program (5 visits, 12-weeks). The case group was treated with pioglitazone 15 mg / day, while the control group received only program. Ultrasound (US) steatometry and genetic testing rs1801282 polymorphism in PPARG gene were performed. Results: Pioglitazone, PPARG rs1801282 genotype, CAP before treatment, previous weight loss attempts, and duration of obesity were associated with the change in controlled attenuation parameter (CAP) during treatment. There was a significant association between the target CAP reduction achievement and pioglitazone treatment (adjusted odds ratio 0.23, 95% CI 0.07-0.73; p = 0.01) with the CC genotype of PPARG gene (adjusted odds ratio 92.9, 95% CI 7.4-1159; p < 0.001) compared to patients with the CG genotype. Conclusions: Pioglitazone and PPARG rs1801282 polymorphism could influence on dynamics of CAP reduction during treatment.
