Summary

To compare the health related quality of life of patients with systemic sclerosis with other rheumatic diseases, such as rheumatoid arthritis, systemic lupus erythematosus and Sjogren's syndrome.

Detailed description

Systemic sclerosis (SSc) is a connective tissue disease characterized by vasculopathy, fibrosis, and autoimmunity. The prognosis of the disease depends on the nature and severity of organ involvement. Patients with SSc suffer from digital ulceration, arthritis, progressive skin tightening, and joint contractures that cause pain and limitation of limb function. The cardiopulmonary system may also be severly affected by SSc in the form of interstitial lung disease and pulmonary arterial hypertension, which leads to reduction in exercise capacity and symptomatic dyspnea. Gastrointestinal involvement by SSc may cause malnutrition, and SSc renal crises may result in renal failure. In addition, cosmetic disfigurement resulting from facial and limb skin involvement may lead to social isolation, mood problems, and significant work disability. It has been reported that health related quality of life (HRQoL) is significantly impared in SSc patients compared to the general population. Moreover, the degree of impairment in SSc patients was comparable to those who suffered from other chronic illnesses such as heart and lung disease, hypertension, diabetes mellitus, and depression. However, there were no studies yet comparing the HRQoL of SSc patients with other rheumatic diseases, such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Especially, information regarding the impact of SSc on functioning and HRQoL in Korean patients is lacking. Therefore, the investigators plan to compare the functioning and HRQoL of patients with SSc with other rheumatic diseases, such as RA, SLE, and Sjogrens's syndrome, and healthy controls. A validated Korean version of the Medical Outcomes Study Short Form 36 (SF36) questionnaire and the EuroQol five dimensions questionnaire (EQ-5D) will be used in this study.

Type	Name	Description
OTHER	validated Korean version of the SF36 and EQ-5D	This is an observational prospective study. SF36 consists of 36 questions that measure patient's HRQoL in 8 domains: physical functioning (PF), role-physical (RP), bodily pain (BP), general health (GH) that represent the physical HRQoL, vitality (VT), social functioning (SF), role-emotional (RE), and mental health (MH) that represent the mental HRQoL. Each domain is scored from 0 (worst health status) to 100 (best health status). The scores of these domains are summarized into the physical component score (PCS) and mental component score (MCS). The EQ-5D questionnaire is made up for 2 components; health state description and evaluation. In description part, health status is measured in terms of 5 dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. In evaluation part, the respondents evaluate their overall health status using the visual analogue scale (EQ-VAS).
