title: IL1A alleles associate with a virological response to  antiretroviral therapy in HIV patients beginning  therapy with advanced disease.
abstract: Among Australians treated for advanced HIV disease, a suboptimal virological response was associated with allele 2 at interleukin 1 alpha (IL1A)-889 and IL1A+4845. This is confirmed and investigated using patients from AIDS Clinical Trials Group study 384 (n=532). Among non-African-American patients with CD4 T-cell count of< or = 100 cells/microl at baseline, IL1A+4845(*)TT was associated with poor virological outcome (P=0.03). Differences were smaller with higher baseline CD4 T-cell counts. IL1A-889 and IL1A+4845 were not in linkage disequilibrium in African-American patients, and IL1A+4845(*)T did not affect outcome.
