Abstract
Introduction
Joint involvement represents the major determinant in quality of life (QoL)in Systemic Lupus Erhytematosus (SLE) patients. However, QoLhas been generally evaluated by non-specific questionnaires. We evaluated the relationship between SLE musculoskeletal manifestations and QoL, assessed by LupusQoL.
Methods
Patients with joint involvement (group A) were compared with those without this feature (group B). Disease activity was assessed by SLEDAI-2k in the whole population, while DAS28 and swollen to tender ratio were applied to assess joint activity. LupusQoL was administered to all the patients.
Results
Group A included 110 patients [M/F 8/102; median age 49 years (IQR 13), median disease duration 156 months (IQR 216)], group B 58 [M/F 11/47; median age 40 years (IQR 15), median disease duration 84 months (IQR 108)].We found significanlty lower values in all the LupusQoL domains except for one (burden to others) in group A in comparison with group B. A significant correlation between DAS28 values and all the LupusQoL domains in group A was found; only three domains correlated with SLEDAI-2k.
Conclusions
SLE-related joint involvement significantly influences disease-specific QoL. DAS28 better correlated with LupusQoL domains in comparison with SLEDAI-2k, confirming the need for specific musculoskeletal activity indices.
