Vaspin, neutrophil gelatinase-associated lipocalin and apolipoprotein levels in patients with psoriatic arthritis.

OBJECTIVES: To examine the relationship between disease activity and vaspin, neutrophil gelatinase-associated lipocalin (NGAL) and apolipoprotein levels in patients with psoriatic arthritis (PsA). BACKGROUND: Psoriatic arthritis (PsA) is a chronic inflammatory arthritis, which is related with psoriasis. Adipokines are the mediators which play a role in metabolic homeostasis and inflammatory conditions. METHODS: The levels of vaspin, NGAL, apolipoproteins and their correlations with disease activity were compared in 50 psoriatic arthritis patients and 36 healthy controls. RESULTS: The levels of vaspin, NGAL and apolipoprotein B/A1 ratio were significantly higher in the patient group (p 0.05). CONCLUSION: This is the first study to have compared vaspin and NGAL levels in patients with PsA. Vaspin and NGAL can be used as a biomarker in PsA. Vaspin, NGAL and dyslipoproteinemia are not correlated with disease activity (Tab. 3, Ref. 63).

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.

Is there any association between irritable bowel syndrome subgroups and autonomous dysfunction.

OBJECTIVE: Irritable bowel syndrome (IBS) is a common functional intestinal disorder. Although there are marked improvements in the conceptualization of IBS pathophysiology in brain-intestinal interaction disorder, there is no definite consensus in the role of autonomic dysfunction (AD) in disease development and symptom progression. The aim of this study was to evaluate autonomous dysfunction in IBS subgroups. PATIENTS AND METHODS: A total of 50 patients and 49 healthy controls were included. IBS subgroup types and demographic characteristics of patients were recorded. AD investigations were made up of parasympathetic and sympathetic tests. RESULTS: There was no statistically significant difference was determined between the groups in accordance to demographic characteristics such as age, gender, BMI and resting heart rate (p > 0.05). Three parasympathetic and one sympathetic autonomic neuropathy tests were found significantly different (respectively p < 0.001, p = 0.001, p = 0.016, p < 0.001, p = 0.375). There were significant decreases in parasympathetic tests in IBS-C patients; however, in the control group, there were significant decreases in sympathetic tests when compared with IBS-D patients (p < 0.001). The severity of AD in IBS-C subgroup was more pronounced than the IBS-D subgroup. No correlation was determined between dysautonomia and disease duration (p > 0.05). CONCLUSIONS: AD may have a role in IBS pathophysiology. Deterioration of the autonomous system not only affects the gastrointestinal system but also other systems including the cardiovascular system. Patients may also be susceptible to more diverse problems.
