Abstract:	Interleukin-1 (IL-1) might play a role in the process of bone loss and hypercalciuria and is therefore considered to be involved in the formation of urinary stones. The aim of this study is to test whether the IL-1 beta promoter region, exon 5 region and IL-1 receptor antagonist gene intron 2 polymorphisms could be genetic markers for the susceptibility to the formation of urinary stones. A control group of 152 healthy people and a group of 105 patients with recurrent calcium oxalate stone were examined in this study. Polymerase chain reaction (PCR) analyzed the variable number tandem repeats at intron 2 of the IL-1Ra gene for the polymorphisms. PCR-based restriction analysis was done for the IL-1 beta gene polymorphisms of the promoter region and exon 5 by the endonucleases Ava I and Taq I, respectively. The polymorphisms studied in the IL-1 beta genes did not reveal a strong association with calcium oxalate stone disease when compared with the control group (promoter region by chi-square test, P = 0.627; exon 5 region by Fisher's exact test, P = 0.403). Only two frequent alleles of the IL-1Ra gene corresponding to one and two copies of an 86-bp sequence repeat were identified by PCR. The result revealed significant differences between control individuals and stone patients (P < 0.01, Fisher's exact test). In addition, the frequency of the type I allele in the stone group (99.0%) was higher than in the control group (94.0%). The odds ratio for the type I allele of the IL-1Ra gene in calcium oxalate stone disease is 6.041 (95% CI: 1.683<similar to>21.687). There is an association between urolithiasis and polymorphism in the IL-1Ra gene. No significant difference was found when dividing the stone patients into groups with normocalciuria and hypercalciuria in relation to these genetic polymorphisms. Further studies of the type I allele of the IL-1Ra gene are worthwhile because of its correlation with stone disease. In our study, neither the IL-1 beta promoter region nor the exon 5 polymorphisms were significantly different when comparing control subjects and calcium oxalate stone patients.
