Objective. To compare serial C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels in juvenile rheumatoid arthritis (JRA) patients and investigate their application as diagnostic parameters and prognostic predictive factors. Methods. We carried out retrospective chart review among JRA patients who were followed-up at the National Taiwan University Hospital (NTUH) between 1994 and 2005. Results. Thirty-nine girls and 68 boys were included in this study. At the time of diagnosis, the prevalence of ESR was significantly greater than that of CRP (86.8% vs. 47.2%, p <0.05). ESR revealed more responsiveness to treatment compared to CRP (SRMs were -0.69 and -0.31, respectively). At the time of diagnosis, high CRP levels (≥ 5mg/dL) correlated with poor therapeutic response, as do positive CRP (>0.8 mg/dL) and high ESR levels (>40 mm/h) after treatment for six months. Overall, initial high CRP levels (≥ 5mg/dL) demonstrated the strongest predictive role of failure of the first remission. Conclusions. For disease diagnosis, ESR can be a better parameter than CRP but a high initial CRP level can strongly predict treatment failure of the first remission.
