Hypersensitivity reaction to abacavir is strongly associated with the presence of the HLA-B*5701 allele. This study was designed to establish the effectiveness of prospective HLA-B*5701 screening to prevent the hypersensitivity reaction to abacavir.

Main Findings

Prospective screening for HLA-B*57:01 eliminated immunologically confirmed abacavir hypersensitivity reactions (p<0.001) and reduced clinically diagnosed hypersensitivity reactions (p<0.001)
