Background: Restless legs syndrome (RLS) is a common sensory motor neurological disorder that is related to iron–dopamine dysregulation and immune system alteration. We aimed to assess the effects of serum hepcidin, an iron-regulating hormone, in drug-naive RLS patients compared to healthy controls and to evaluate its role in helping to predict clinical improvement after treatment with dopamine agonist. Methods: Nonanemic and drug-naive RLS patients (n = 18) and healthy controls (n = 15) were enrolled. The serum hepcidin and iron-related values in the serum were measured upon the first visit in both groups and 12 weeks later after dopaminergic treatment in 12 patients. Information about sociodemographic characteristics, sleep-related profiles, mood and anxiety was obtained upon the first visit in all participants as well as after treatment in RLS patients. Results: Serum hepcidin levels exhibited no significant differences between patients with drug-naïve RLS and healthy controls at diagnosis (7.1 ± 2.4 vs. 7.0 ± 3.2 ng/mL, p = 0.357). Decreased hepcidin levels were significantly associated with decreased RLS severity (β = 0.002, 95% CI = 0.00−0.00, p = 0.005) and improved quality of life (β = 0.002, 95% CI = 0.00−7.01, p = 0.044) in a dose-dependent manner after 12 weeks of treatment with a dopamine agonist. This association was independent of age, sex, inflammatory markers, sleep quality, insomnia, daytime sleepiness, depression and anxiety. Conclusions: This study demonstrates the role of hepcidin in evaluating the positive therapeutic response in RLS.

Abstract Introduction Restless legs syndrome (RLS) is a common sensory motor neurological disorder that is related to iron-dopamine dysregulation and immune system alteration. Hepcidin is the key regulatory hormone of systemic iron homeostasis and is related to inflammatory processes. We aimed to evaluate the clinical utility of hepcidin as a diagnostic biomarker and index of therapeutic responses in RLS patients after dopaminergic treatment. Methods Non-anemic and drug-naive RLS patients (n=18) and healthy controls (n=15) were enrolled. Hepcidin (pre-prohepcidin) and iron-related values in serum were measured upon the first visit in both groups and 12 weeks later after dopaminergic treatment in 12 RLS patients. Information about sociodemographic characteristics, sleep-related profiles, mood, and anxiety was obtained upon the first visit in all participants as well as after treatment in RLS patients. Results Hepcidin levels exhibited no significant differences between patients with drug-naïve RLS and healthy controls at a diagnosis (7.1 ± 2.4 vs. 7.0 ± 3.2 ng/ml, p = 0.978). Decreased hepcidin levels were significantly associated with decreased RLS severity (β = 0.002, 95% CI = 0.00−0.00, p = 0.005) and improved quality of life (β = 0.002, 95% CI = 0.00−7.01, p = 0.044) in a dose-dependent manner after 12 weeks of treatment with a dopamine agonist. This association was independent of age, sex, inflammatory markers, sleep quality, insomnia, daytime sleepiness, depression, and anxiety. Conclusion This study demonstrates a role of hepcidin as a predictor of therapeutic responses in RLS patients.

Background: Butyric acid, a major short-chain fatty acid (SCFA), has an important role in the microbiota–gut–brain axis and brain function. This study investigated the role of butyric acid in treatment response in drug-naïve first episode schizophrenia.Methods: The study recruited 56 Chinese Han schizophrenia inpatients with normal body weight and 35 healthy controls. Serum levels of butyric acid were measured using Gas Chromatography-Mass Spectrometer (GC-MS) analysis at baseline (for all participants) and 24 weeks after risperidone treatment (for patients). Clinical symptoms were measured using the Positive and Negative Syndrome Scale (PANSS) for patients at both time points.Results: At baseline, there was no significant difference in serum levels of butyric acid between patients and healthy controls (p = 0.206). However, there was a significant increase in serum levels of butyric acid in schizophrenia patients after 24-week risperidone treatment (p = 0.030). The PANSS total and subscale scores were decreased significantly after 24-week risperidone treatment (p's < 0.001). There were positive associations between baseline serum levels of butyric acid and the reduction ratio of the PANSS total and subscale scores after controlling for age, sex, education, and duration of illness (p's < 0.05). Further, there was a positive association between the increase in serum levels of butyric acid and the reduction of the PANSS positive symptoms subscale scores (r = 0.38, p = 0.019) after controlling for potential confounding factors.Conclusions: Increased serum levels of butyric acid might be associated with a favorable treatment response in drug-naïve, first episode schizophrenia. The clinical implications of our findings were discussed.

Abstract Objectives Restless legs syndrome (RLS) is a common neurological condition. Oxidative stress plays an important role in its pathogenesis. Thiol-disulphide homeostasis (TDH) is a new biomarker of oxidative stress. We studied plasma TDH to determine whether TDH could be used as a new biomarker for RLS and evaluated correlations between TDH and various disease severity rating scales. Methods A total of 25 RLS patients and 25 healthy controls were included into the study. TDH status was determined using an automated spectrophotometric analysis method and correlations were analyzed between the TDH status and various disease rating scales in the RLS patients. Results Plasma total (401 ± 27 μmol/L) and native thiol (354 ± 30 μmol/L) levels were significantly lower, but disulphide level (24 ± 6 μmol/L) was significantly (<0.0001) higher in the RLS patients compared to the controls (455 ± 36, 424 ± 37, 15 ± 5 μmol/L, respectively). The disulphide/native thiol and disulphide/total thiol ratios increased, in contrast, native thiol/total thiol ratio decreased significantly in the RLS patients compared to the healthy controls (<0.0001). The disulphide levels correlated positively with age and various rating scores of the RLS patients. International Restless Legs Syndrome Study Group (IRLSSG) rating score and age correlated negatively with the total and native thiol levels. Conclusions Our findings indicate increased oxidative stress in the RLS patients reflected by decreased native and total thiol, and increased disulphide levels and positive correlations between the disulphide levels and various rating scores. We suggest dynamic TDH status to be used as a novel biomarker for the diagnosis and follow-up of the RLS patients.

A total of 135 consecutive, unrelated, multiple sclerosis (MS) patients were interviewed for symptoms suggestive of restless legs syndrome (RLS) and REM sleep behavior disorder (RBD), using semi-structured questionnaires. Some 118 unrelated healthy controls of similar sex and age distribution were included for comparison. Patients and controls with equivocal symptoms were re-evaluated by a sleep disorders specialist and video-polisomnography in those who fulfilled the criteria for RBD. We did not find significant differences in frequency (13.3 versus 9.3%), proportion of females (66.7 versus 58.5%), and mean age (42.1±12.6 versus 43±7.8 years) among MS patients and controls with RLS. RBD was found in three patients (1.4%), one associated with antidepressant intake, but in none of the controls. Our study shows that RLS in MS is not more frequent than in the general population, and that RBD, although uncommon, may occur in the setting of this neurological disease.

Background: Leprosy is a chronic infectious disease primarily affecting the peripheral nervous system and skin. Multibacillary leprosy is associated with nerve damage which could contribute to myelin alteration. As ceramide is a constituent of myelin sheath, the present study aimed to compare anti-ceramide antibody titre in paucibacillary and multibacillary leprosy patients with controls. Methodology: Serum levels of anti-ceramide antibody were measured using enzyme-linked immunosorbent assays (ELISA) in 50 leprosy patients (25 paucibacillary and 25 multibacillary) and 25 healthy controls. Results were reported in OD units as mean ± SD and analyzed by Chi square test (significance at p < 0.05). Results: Patients suffering from multibacillary leprosy had significantly higher anti-ceramide antibody serum levels compared to paucibacillary leprosy patients and healthy controls (p < 0.005). Conclusions: Since nerve damage is the most debilitating effect of leprosy, the search for a serum marker for assessing nerve damage is required in countries where leprosy is still widespread. In multibacillary leprosy patients, the role of anti-ceramide antibody as a marker for nerve damage should be explored.

Introduction. Pityriasis rosea (PR) is an exanthematous disease related to human herpesvirus- (HHV-) 6/7 reactivation. The network of mediators involved in recruiting the infiltrating inflammatory cells has never been studied.Object. To investigate the levels of serum cytokines, growth factors, and chemokines in PR and healthy controls in order to elucidate the PR pathogenesis.Materials and Methods. Interleukin- (IL-) 1, IL-6, IL-17, interferon- (IFN-)γ, tumor necrosis factor- (TNF-)α, vascular endothelial growth factor (VEGF), granulocyte colony stimulating factor (G-CSF), and chemokines, CXCL8 (IL-8) and CXCL10 (IP-10), were measured simultaneously by a multiplex assay in early acute PR patients’ sera and healthy controls. Subsequently, sera from PR patients were analysed at 3 different times (0, 15, and 30 days).Results and discussion. Serum levels of IL-17, IFN-γ, VEGF, and IP-10 resulted to be upregulated in PR patients compared to controls. IL-17 has a key role in host defense against pathogens stimulating the release of proinflammatory cytokines/chemokines. IFN-γhas a direct antiviral activity promoting NK cells and virus specific T cells cytotoxicity. VEGF stimulates vasculogenesis and angiogenesis. IP-10 can induce chemotaxis, apoptosis, cell growth, and angiogenesis.Conclusions. Our findings suggest that these inflammatory mediators may modulate PR pathogenesis in synergistic manner.
