BACKGROUND: Children infected with the human immunodeficiency virus (HIV) often have hypergammaglobulinemia, causing elevation of the erythrocyte sedimentation rate (ESR). This study was done to determine whether C-reactive protein (CRP) is a better indicator of acute infection than ESR in HIV-infected children. METHODS: Erythrocyte sedimentation rate, CRP, and immunoglobulin G (IgG) levels were measured in sick and otherwise healthy HIV-infected children. McNemar's test was used to compare ESR and CRP. RESULTS: In 22 of the 26 cases (85%), the IgG level was elevated, and in all cases ESR was elevated. In 20 of these 22 (91%), both ESR and CRP were elevated. Of the 18 controls, 17 (94%) had elevated IgG, 14 of 17 (82%) had elevated ESR, and 1 (7%) had elevated CRP. The sensitivity for ESR and CRP was 96% and 92%, respectively, and the specificity for ESR and CRP was 17% and 94%, respectively. CONCLUSIONS: Since CRP is more specific than ESR in predicting acute infection in HIV-infected children, it should be used in the evaluation of acute infection in this population.
