Abstract
Objectives
Restless legs syndrome (RLS) is a neurological disease with a chronic course that is characterised by sleep disorders and sensorimotor impairment. The aim of this study was to evaluate the prevalence and severity of RLS in psoriatic arthritis (PSA) patients and those with psoriasis (P).
Patients and methods
The study included 50 patients with psoriasis (28 females, 22 males), 50 PSA patients (33 females, 17 males) and 50 healthy control subjects (34 females, 16 males), and all 3 groups were matched with respect to age, gender and body mass index (BMI). Evaluations were made using the International RLS Rating Scale, Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, Insomnia Severity Index, Fatigue Severity Scale (FSS), Beck Depression Index (BDI) and the SF-36 quality of life scores.
Results
RLS was determined at a higher rate in the PSA patients (64.0%), compared to the P group (20.0%, p < 0.001) and the control group (14.0%, p < 0.001). The number of moderate and severe RLS cases was significantly higher in the PSA group (68.7%) compared to the P group (30%, p < 0.001) and the control group (0%, p < 0.001). In regression analysis, an independent correlation was found between the RLS score and PSQI (beta [β] = 0.269, p = 0.002), FSS (β = 0.243, p = 0.003), SF-36 physical score (β = 0.242, p = 0.004) and BDI (β = 0.177, p = 0.036).
Conclusion
RLS was determined in PSA patients at a higher rate than in psoriasis patients. The presence of RLS in PSA and psoriasis patients is related to impairments in sleep and quality of life, fatigue and depression.
