Arthritis in association with human immunodeficiency virus infection in Black African children: causal or coincidental?

ABSTRACT

OBJECTIVES: To compare human immunodeficiency virus (HIV)-infected and HIV-uninfected children with arthritis of unknown origin to determine whether the association between HIV infection and arthritis is causal or coincidental. METHOD: Retrospective review of 132 children with arthritis who were tested for HIV infection. RESULTS: Thirty-five (27%) of the children were HIV infected and the male to female ratio was 2.51 (P = 0.02). Arthritis was the presenting feature of HIV infection in 78% of these children. The remaining 97 (73%) were diagnosed as having juvenile idiopathic arthritis. 'Spondyloarthropathy-like' features were found in 34% of HIV-infected children compared with 5% of uninfected children. CONCLUSION: The high prevalence of HIV infection in 27% of children, the predominance of males and the increased prevalence of 'spondyloarthropathy-like' features, supports a causal relationship between HIV infection and arthritis.
