A comparative evaluation of quality of life and life satisfaction in patients with psoriatic and rheumatoid arthritis

Both rheumatoid arthritis (RA) and psoriatic arthritis (PsA) have a negative impact on patients' quality of life (QOL). The aim of this study was to compare QOL and life satisfaction in patients with RA and PsA. Forty patients with PsA, 40 patients with RA, and 40 healthy control subjects were included in the study. Demographic data and clinical characteristics including age, sex, disease duration, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), peripheral pain assessed by visual analog scale (VAS) and Larsen scores of hand X-rays were recorded. Nottingham Health Profile (NHP) was used to evaluate QOL, and Life satisfaction index (LSI) was used to measure psychological well-being in both groups. The demographic data of the subjects were similar between the groups. The scores of all NHP subscales were significantly higher and the scores of LSI were significantly lower in PsA and RA patients than in control subjects. The inflammation markers including ESR, CRP, pain by VAS and Larsen scores were found to be significantly higher in RA patients. The scores of LSI were similar between the groups. Although the scores of physical domains of NHP (pain and physical disability) were statistically higher in RA patients (p0.05). Both PsA and RA patients had disturbed QOL and decreased life satisfaction. In conclusion, peripheral joint damage, inflammation, and physical disability are significantly greater in RA but psychosocial reflection of QOL and life satisfaction are the same for both groups which can be explained by the additional impact of skin disease in patients with PsA.
