Background:
The rheumatoid factor (RF) blood test is the most commonly adopted test for the diagnosis of rheumatoid arthritis (RA). RA patients who are seropositive for RF might face a greater likelihood of developing more aggressive symptoms.
Methods:
Our goal was to study the demographic and clinical characteristics, as well as their correlation with RF seropositivity, among a series of 80 RA patients aged ≥ 18 years who attend Hospital Universiti Sains Malaysia (HUSM).
Results:
Of the 80 RA patients included in this study, 66 (82.5%) were female and 14 (17.5%) were male. No significant associations between RF seropositivity and demographic and/or clinical characteristics or other laboratory investigations were observed, including gender, morning stiffness, individual joint involvement (from multiple sites of the body), and erythrocyte sedimentation rate (ESR) measurement. However, a significant association between RF seropositivity and patients aged ≥ 50 was found (P = 0.032).
Conclusion:
RF seropositivity was found to be more common in much older RA patients.
