Evaluation of restless legs syndrome and sleep disorders in patients with psoriatic arthritis.

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 [ß] = 0.269, p = 0.002), FSS (ß = 0.243, p = 0.003), SF-36 physical score (ß = 0.242, p = 0.004) and BDI (ß = 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.

Atherogenic index of plasma may be strong predictor of subclinical atherosclerosis in patients with Behçet disease.

OBJECTIVES: Behcet's disease (BD) is a systemic vasculitis characterized by cardiovascular complications. Early diagnosis of these complications can reduce morbidity and mortality. Carotid artery intima-media thickness (cIMT) and the logarithmic value of triglyceride to high density lipoprotein ratio (atherogenic index of plasma, AIP) are good markers of atherosclerosis. The purpose of this study was to investigate whether AIP is a predictive marker of subclinical atherosclerosis in BD patients. PATIENTS AND METHODS: A total of 84 BD patients (60 male, 24 female) and 84 healthy control individuals (58 male, 26 female) were included in this study. cIMT measurements were made, and AIP values were calculated. RESULTS: cIMT (p < 0.001) and AIP (p < 0.001) values of the BD patients were higher than those of the control group. A strong independent relationship was found between the AIP value and cIMT (ß = 0.232, p = 0.018). In the subgroup analysis, the cIMT and AIP values of male BD patients were higher than those of female BD patients. CONCLUSION: Increased AIP and cIMT values can be a good marker for subclinical atherosclerosis in BD patients, especially in male BD patients.
