A genotype in the IL-1 gene cluster is associated with an increased risk of periodontitis. We investigated whether polymorphisms in the IL-1A +4845 and IL-1B +3954 loci affect the periodontal status of HIV-infected Brazilians on HAART. HIV-positive and HIV-negative subjects with periodontitis were genotyped for IL-1 by polymerase chain reaction and restriction enzyme digestion. Only 11.4% of patients were genotype positive. No associations between genotype positivity and HIV infection or periodontal status were found in this population.
