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

OBJECTIVE

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.

PATIENTS AND

METHODS

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

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.

CONCLUSION

Conclusions

Pioglitazone and PPARG rs1801282 polymorphism could influence on dynamics of CAP reduction during treatment.
