Abstract
Objective Interieuldn-10 (IL-10) is a major immunoregutatorycytokine and its gene plays a fundamental role in anti inflammatory and immunosuppressive activity. This study aimed to examine the association between the IL10 gene promoter -1082G/A polymorphism (rs1800896) and tardive dyskinesia (TD) in schizophrenia. Methods Two hundred and eighty unrelated Korean schizophrenic patients participated in this study (105 TD and 175 non-TD patients). TD was diagnosed using the Research Diagnostic Criteria kw TD and Abnormal Involuntary Movement Scale (AIMS). Genotyping was per-limited by RT-PCR and high-resolution melting curve analysis. Results The distributions of genotypic frequencies did not differ between patients with and without TD (chi(2) =4.33, p=0.115). However, allelic frequencies of the two groups were different (chi(2) =4.45, p=0.035); the A allele frequency was higher in TD. The total AIMS scores of the three genotypes were not different (F=133, p=0.266). However, the total AIMS scores of the A allele carrier and the A allele non-carrier were significantly different (t=5.79, p<0.001). Logistic regression analaysis showed that IL10 -1082G/A genotype significantly predicts presence of TD (p=0.045) after adjusting for covariates such as age and treatment duration. Conclusion This finding suggests that the A allele of rs1800896 may be associated with TD development following a low IL-10 function.
