Quality of life assessment in Egyptian rheumatoid arthritis patients: Relation to clinical features and disease activity

AbstractAim of workTo assess the impact of rheumatoid arthritis (RA) on the health related quality of life (QoL) of patients, using the 36-item short form (SF-36) and to study the influence of different disease variables.Patients and methodsEighty-six RA patients were recruited from the Rheumatology and Rehabilitation outpatient of Assiut University Hospital. Forty-three, age and sex matched subjects were included as controls. The QoL was measured in all subjects using the SF-36 health survey. Disease activity was assessed in RA patients by the disease activity score (DAS28).ResultsAll domains of the SF36 were significantly lower in the patients (p<0.0001). Patients with a lower educational level and those unemployed had significantly lower SF36 components. Those with a disease duration >5years, positive rheumatoid factor and higher disease activity had a significantly lower SF36 physical component. Patients receiving hydroxychloroquine or prednisolone had significantly lower mental component. Significant negative correlation of the SF36 physical and mental components was found with both disease duration (p=0.01 and p<00001 respectively) and DAS28 (p<0.0001 for both). Rheumatoid factor negatively correlated with the physical component (p<0.0001). Regression analysis showed that disease duration was the most profound predictor of both SF36 components (p
