Objective

To evaluate the differences between the responses to treatment using DAS28 based on erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in male and female patients. We then analyzed the individual behaviour of each component in a cohort of early arthritis patients in zone 2 of Madrid.

Patients and methods

We studied a total of 134 patients (77.6%women) who met the American College of Rheumatology (ACR) criteria for the diagnosis of rheumatoid arthritis (RA) belonging to an early arthritis register of the Hospital de La Princesa. We performed 4 visits following a standardized protocol which included necessary variables to calculate the DAS28 with ESR and CRP as well as determining the treatment received by the patients. We analyzed the differences in responses to treatment in males and females using both indexes, as well as their component and the assessment of the disease by the physician.

Results

Women had higher disease activity and disability at baseline. Although they received more intensive treatment, their average value of DAS28 remained significantly higher compared to men during the follow-up. By contrast, the global disease assessment evaluated by the patient and by the physician remained similar in both gender. When we analyze the DAS28 components separately, it was observed that this discrepancy was due mainly to the tender joints count and the ESR.

Conclusions

Women with early RA have higher DAS28ESR scores as a result of higher tender joint counts and ESR. This may represent bias when assessing the response to treatment using the DAS28ESR.
