Abstract
OBJECTIVES: This study aimed to evaluate health related quality of life (HRQOL) in Egyptian children with systemic lupus erythematosus (SLE) using 3 different tools. METHODS: In this questionnaire-based study, 100 children with SLE were included. HRQOL was assessed using the Pediatric Quality of Life Inventory Generic Core Scales (PedsQL™ 4.0 GCS), PedsQL™ 3.0 Rheumatology Module (PedsQL3-RM) and the Simple Measure of the Impact of Lupus Erythematosus in Youngsters (SMILEY). SLE disease activity index (SLEDAI) was used to evaluate activity and SLE International Collaborating Clinics/ American College of Rheumatology Damage Index (SDI) was used to evaluate chronic damage. RESULTS: All mean scores of PedsQL(TM)4.0 GCS domains in SLE patients were lower than published normative data and previously published results of Egyptian healthy controls (p < 0.001). All mean scores of PedsQL-3RM domains were significantly lower than published normative data except for the treatment and pain and hurt domains (p = 0.1, 0.2 respectively). SMILEY scores were low and the lowest domain scores was "Burden of SLE". Longer duration of illness, higher cumulative steroid doses, higher SLEDAI and SDI scores and presence of obesity were associated with lower scores for all 3 tools (p < 0.001). CONCLUSION FOR PRACTICE: The Arabic copies of PedsQL™ 4.0 GCS, PedsQL3-RM and SMILEY are easily used for Arabic speaking subjects and easily interpreted by physician and can be implemented for frequent monitoring of SLE HRQOL. Controlling the disease activity and using lowest doses of steroids and other immunosuppressive drugs are the corner stone strategies for improving HRQOL in SLE children.
