Abstract

The severity of hepatic injury depends upon cytokines. Previous studies associated IL-1RN allele 2 with IL-1β production. Hence, we examined the association of IL-1 RN and IL-1β polymorphisms with ARV-associated hepatotoxicity. Genotyping of IL-1RN (VNTR), IL-1β (-511C/T) polymorphisms was done in 162 HIV-infected patients, 34 with ARV hepatotoxicity, 128 without hepatotoxicity, and 152 healthy controls using PCR and PCR-RFLP method. The haplotypes 1T and 2C enhanced the risk for severe hepatotoxicity (OR = 1.41, P = 0.25; OR = 1.67, P = 0.31). IL-1β-511TT genotype significantly represented among tobacco using HIV-infected individuals compared to nonusers (OR = 3.74, P = 0.05). IL-1β-511TT genotype among alcohol users increased the risk for hepatotoxicity (OR = 1.80, P = 0.90). IL-1β-511CT and -511TT genotypes overrepresented in alcohol using HIV-infected individuals (OR = 2.29, P = 0.27; OR = 2.64, P = 0.19). IL-RN 2/2 and 1/3 genotypes represented higher in nevirapine using hepatotoxicity patients (OR = 1.42, P = 0.64, OR = 8.79, P = 0.09). IL-1β-511CT and -511 TT genotypes among nevirapine users enhanced the risk for severe hepatotoxicity (OR = 4.29, P = 0.20; OR = 1.95, P = 0.56). IL-1β-511CT and -511TT genotypes were overrepresented in combined nevirapine and alcohol using HIV-infected individuals as compared to nevirapine users and alcohol nonusers (OR = 2.56, P = 0.26; OR = 2.84, P = 0.24). IL-1β-511TT genotype with tobacco, alcohol, and nevirapine usage revealed a trend of risk for the development of ARV-associated hepatotoxicity and its severity.
