title: Impact of Joint Involvement on Patients Reported Outcomes in Systemic Lupus Erythematosus.
abstract: OBJECTIVE
  Joint involvement is common among patients with systemic lupus erythematosus (SLE). Aim of this work was to evaluate the correlation between the presence of joint involvement and patient-reported pain, perception of disease activity, general health and quality of life.
  
  
  METHODS
  Fifty consecutive SLE patients were enrolled in the study. All patients underwent a complete clinical evaluation including a 44-joint count; in addition, an ultrasound evaluation of joint involvement of hands and wrists was performed. The following patients reported outcomes (PROs) were completed: Visual Analog Scales 0-100 mm (VAS) evaluating patients reported pain, patient's perception of global disease activity and general health (GH) and a validated Italian version of the Health Assessment Questionnaire (HAQ).
  
  
  RESULTS
  Fourteen patients (28%) reported a significant morning stiffness lasting for more than 30 minutes; hand or wrist arthritis was clinically detectable in 10 (20%) patients, while the US evaluation exhibited at least one joint or tendon pathology in 18 patients (36%). The mean VAS score for pain and disease activity perception was 27 (±27.7) mm and 25.3 (±25.2) mm, respectively, the mean of GH score was 33.2 (±24.3) mm, and the mean HAQ score was 0.34 (±0.5). A significant correlation was observed between VAS score for pain, patient's perception of disease activity and GH and the presence of arthritis.
  
  
  CONCLUSIONS
  PROs may play an important role in guiding therapeutic decisions and suggest the utility of ultrasound evaluation in patients reporting articular symptoms.
