OBJECTIVE: In this study we have analyzed GSTM1, GSTT1 and GSTP1 polymorphisms in patients with juvenile idiopathic arthritis (JIA), to investigate a possible role of these genes as genetic components of the disease. METHODS: A total of 103 individuals (49 oligoarticular, 41 polyarticular and 13 systemic) were analyzed for the three polymorphisms, using a PCR/RFLP methodology. RESULTS: We have observed significantly increased frequencies of individuals with GSTT1 null genotype in JIA patients comparing to controls (37% x 21%; p=0.0183). There was a 2-fold increased risk (OR 2.2, 95% CI 1.2-4.1) associating the disease with the GSTT1 null genotype. Considering the subgroups (oligoarticular, polyarticular and systemic), the results indicated an association between polyarticular and systemic patients and the GSTT1 null genotype. There was a 2-fold increased risk for polyarticular patients (OR 2.4, 95%, CI 1.1-5.4), and a 4-fold increased risk for systemic patients (OR 4.4, 95%, 1.3-14.5). CONCLUSION: The GSTT1 null genotype seems to be involved in polyarticular and systemic JIA.
