Health-related quality of life assessed by LupusQoL questionnaire and SF-36 in Turkish patients with systemic lupus erythematosus.

The LupusQoL is a disease-specific health-related quality of life (HRQoL) measure for patients with lupus. We conducted this study to compare the efficiency of LupusQoL-TR (validated Turkish version of the LupusQoL questionnaire) with the 36-item Short-Form Health Survey (SF-36), a generic quality of life (QoL) scale, in Turkish patients with lupus. Both questionnaires were conducted at a single visit to the clinic. Disease activity was measured with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Associations between the LupusQoL-TR and SF-36 domains were examined while also examining age, disease duration, and disease activity for each questionnaire. Descriptive statistics, Spearman's correlation coefficients, and Students t test were performed to analyze the data. A total of 113 consecutive patients with lupus (F/M 108:5, mean age 40.6 ± 11.9 years, mean disease duration 8.5 ± 7.0 years) were included, and 69 % of these were active. The median SLEDAI score was 2 (0-24), the mean global LupusQoL-TR score was 60.9 ± 23.3, and the mean SF-36 score was 41.2 ± 9.0. There was a significant correlation between LupusQoL-TR and SF-36 mean scores (r = 0.83; p < 0.001). QoL assessed by LupusQoL-TR and SF-36 did not correlate with disease activity (r = -0.11; p = 0.244 and r = -0.03; p = 0.721, respectively). LupusQoL-TR and SF-36 questionnaires were beneficial instruments in evaluating HRQoL in Turkish lupus patients. However, LupusQoL-TR and SF-36 were not associated with SLEDAI scores, which suggested that QoL might be affected by other factors besides disease activity, especially in clinically inactive or mildly active patients.

Anxiety and depression predict quality of life in Turkish patients with systemic lupus erythematosus.

OBJECTIVES: The aim of our study was to evaluate quality of life (QoL) in patients with systemic lupus erythematosus (SLE) and assess the impact of disease activity and psychological distress on health-related quality of life (HRQoL) in Turkey. METHODS: The Medical Outcomes Study Short Form (SF) -36 was used in a cohort of 113 consecutive patients with SLE and 123 age- and gender-matched healthy subjects to measure HRQoL. Patients' disease activity was assessed with SLE disease activity index (SLEDAI) and psychological distress was evaluated by the Hospital Anxiety and Depression Scale (HADS) for all participants. Patients' demographic and clinical data were recorded at the time of HRQoL and HADS testing. Multiple logistic regression analysis was performed to explore the relationships between demographics, disease duration, disease activity as well as psychological (anxiety and depression) variables and the HRQoL. RESULTS: SLE patients have lower quality of life than healthy controls. No relationship between HRQoL and SLE activity or disease duration were observed. Patients with anxiety and/or depression reported worse SF-36 scores than those without psychological distress. The results of multivariate analysis suggested that HADS-A, HADS-D scores and working status were associated with the impairment of HRQoL. CONCLUSIONS: HRQoL is impaired in patients with SLE and is associated with mood disorders. Physicians should pay close attention to detect anxiety and depression and manage them in order to improve the quality of life in patients with SLE.
