title: [Comparison of health-related quality of life between patients with rheumatic diseases and a control group].
abstract: OBJECTIVE
  To compare the health-related quality of life between patients with rheumatoid arthritis and systemic lupus erythematosus and a control group.
  
  
  METHODS
  Eighty-eight patients with rheumatoid arthritis, 40 patients with systemic lupus erythematosus and 40 women who did not suffer from any inflammatory joint disease (control group) participated in this comparative study. The questionnaires they completed included information about their sociodemographic status and comorbidities. Patients with rheumatoid arthritis and systemic lupus erythematosus were assessed for pain (visual analogical scale), extra-articular manifestations, and disease activity; also they completed questionnaires for the evaluation of physical function (Health Assessment Questionnaire--HAQ) and burden of arthritis (Arthritis Impact Measurement Scale). All groups under investigation completed the health-related quality questionnaire SF-36 (Medical Outcomes Study Short Form-36) validated in Lithuania.
  
  
  RESULTS
  The study of health-related quality of life of women with rheumatic disease showed that patients with systemic lupus erythematosus had stronger pain (p=0.017). It was also found that the activity of patients with rheumatoid arthritis was more limited because of emotional problems (p=0.038). No significant differences were found in other areas of life quality. It was recognized that in comparison to other groups, the quality of life of the control group was better (p=0.000) from the point of view of physical activity, limitations of activity because of physical problems, pain, overall health status and social relations. The psychological status of the latter was undoubtedly worse.
  
  
  CONCLUSIONS
  In this study it was found that all patients with rheumatoid arthritis and systemic lupus erythematosus had evaluated most of the aspects of health-quality very similarly. Significant differences have been determined when assessing pain and limitation of activity because of emotional problems. The health-related quality of life of the control group is definitely better than that of the rest in most aspects, except for the psychological one.
