Pilloni G, Best P, Kister I, Charvet L. Heart Rate Variability (HRV) serves as an objective correlate of distress and symptom burden in multiple sclerosis. Int J Clin Health Psychol 2024; 24:100454. [PMID: 38525015 PMCID: PMC10958478 DOI: 10.1016/j.ijchp.2024.100454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 03/08/2024] [Indexed: 03/26/2024] Open
Abstract
Background Autonomic nervous system (ANS) dysfunction is frequently seen in people living with multiple sclerosis (MS). Heart rate variability (HRV) is an easy and objective index for evaluating ANS functioning, and it has been previously used to explore the association between ANS and the experience of symptom burden in other chronic diseases. Given ANS functioning can be influenced by physical and psychological factors, this study investigated whether emotional distress and/or the presence of ANS dysfunction is associated with symptom severity in people living with MS. Methods Participants with MS and healthy controls (HC) with no history of cardiac conditions were recruited to self-collect HR data sampled from a chest strap HR monitor (PolarH10). Short-term HR signal was collected for five minutes, and time and frequency HRV analyses were performed and compared between groups. HRV values were then compared to self-reported distress (Kessler Psychological Distress Scale) and MS participants' self-reported measures of symptom burden (SymptoMScreen). Results A total of n = 23 adults with MS (51 ± 12 years, 65 % female, median Patient Determined Disease Steps [PDDS]: 3.0) and n = 23 HCs (43 ± 18 years, 40 % female) completed the study procedures. All participants were able to complete the chest strap placement and HR data capture independently. Participants with MS, compared to the HC participants, had a significantly lower parasympathetic activation as shown by lower values of the root mean square of successive differences between normal heartbeats (RMSSD: 21.86 ± 9.84 vs. 43.13 ± 20.98 ms, p = 0.002) and of high-frequency (HF) power band (HF-HRV: 32.69 ± 12.01 vs. 42.39 ± 7.96 nu, p = 0.016), indicating an overall lower HRV in the MS group. Among individuals with MS, HF-HRV was significantly correlated with the severity of self-reported MS symptoms (r = -0.548, p = 0.010). Participants with MS also reported higher levels of distress compared to HC participants (18.32 ± 6.05 vs. 15.00 ± 4.61, p = 0.050), and HRV correlated with the severity of distress in MS participants (r = -0.569, p = 0.007). A significant mediation effect was also observed, with emotional distress fully mediating the association between HRV and symptom burden. Conclusions These findings suggest the potential for ANS dysfunction, as measured by HRV (i.e., lower value of HF power), to be utilized as an objective marker of symptom burden in people living with MS. Moreover, it is apparent that the relationship between HRV and symptom burden is mediated by emotional distress.

Abstract
Interleukin 33 (IL-33) belongs to the IL-1 family and is localized in the nucleus. IL-33 is primarily composed of three distinct domains, namely the N-terminal domain responsible for nuclear localization, the intermediate sense protease domain, and the C-terminal cytokine domain. Its specific receptor is the suppression of tumorigenicity 2 (ST2), which is detected in serum-stimulated fibroblasts and oncogenes. While most other cytokines are actively produced in cells, IL-33 is passively produced in response to tissue damage or cell necrosis, thereby suggesting its role as an alarm following cell infection, stress, or trauma. IL-33 plays a crucial role in congenital and acquired immunity, which assists in the response to environmental stress and maintains tissue homeostasis. IL-33/ST2 interaction further produces many pro-inflammatory cytokines. Moreover, IL-33 is crucial for central nervous system (CNS) homeostasis and the pathogenic mechanisms underlying CNS degenerative disorders. The present work summarizes the structure of IL-33, its fundamental activities, and its role in immunoregulation and neurodegenerative diseases. Therefore, this work proposes that IL-33 may play a role in the pathogenic mechanism of diseases and can be used in the development of treatment strategies.

Abstract
Multiple sclerosis (MS) is a chronic progressive demyelinating disease of the central nervous system (CNS), which also affects the autonomic nervous system (ANS). Manifestations of MS in the ANS include urological, sexual, gastrointestinal, cardiovascular, and thermoregulatory disorders as well as increased fatigue. These problems are common yet are often underestimated due to the non-specificity of the symptoms and the limited evaluation of the ANS in the usual clinical practice. Most of these symptoms seem to be related to localized lesions in the CNS. However, the mechanisms by which these disorders are caused in MS have not been fully investigated, thus preventing any focused etiological treatment. The most common disorders of the ANS in MS represent a challenge for clinicians due to the variability of the clinical picture and our minimal data on their diagnosis and treatment. Early diagnosis and initiation of individualized treatment regimens, often in need of multiple approaches, seem to yield the best results in managing ANS dysfunction in MS patients.

Abstract
This review article addresses the complex issues faced by individuals with Multiple Sclerosis (MS) who are planning a family, becoming pregnant, or wishing to breastfeed their baby. Recommendations and guidelines were discussed and agreed upon by neurologists, neuroradiologists, nurses, and pharmacists involved in the management of MS in the Kingdom of Saudi Arabia (KSA). MS itself does not harm a pregnancy, and people with MS of childbearing age can be encouraged to enjoy family life. Family planning should be a part of the initial conversation with a newly diagnosed patient of childbearing age. Interferons and glatiramer acetate can be continued throughout pregnancy and can be administered during breastfeeding if the benefits outweigh the risks. These DMTs may be considered for a woman with well-controlled MS who is planning a pregnancy or otherwise not using contraception, according to an individualized risk-benefit analysis. The use of contraception should be maintained during the administration of other disease-modifying therapies (DMTs). Natalizumab can be administered at a reduced administration frequency to women with high MS disease activity up to 30 weeks gestation (this agent may induce hematological abnormalities in the fetus). Other DMTs should be withdrawn for variable periods before contraception is stopped and immediately after the discovery of a pregnancy (beware of rebound disease activity after withdrawing natalizumab or fingolimod). Resumption of treatment should not be delayed in women at risk of relapse during the postpartum period and especially in those who do not wish to breastfeed.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE Bowel and anorectal dysfunctions are common in patients with multiple sclerosis (pwMS). The use of validated questionnaires is recommended in the initial assessment and patient's follow-up. The Neurogenic Bowel Dysfunction (NBD) score is the most used questionnaire but has been developed in spinal cord injured patients and has never been validated in other neurological diseases. We aimed to assess NBD's relevance in pwMS. SETTINGS Monocentric study in a tertiary neuro-urology department. METHODS A retrospective study in pwMS consulting for the first time in our department, that fulfilled the NBD questionnaire between 2010 and 2021 was performed. Qualitative and quantitative answers for each question were analyzed. Content validity and internal consistency were evaluated. RESULTS One hundred thirty-five pwMS (mean age 47.1, 58% of women) fulfilled the NBD questionnaire. Mean NBD score was 6.0 (SD 6.1) and 75% of patients had a score <9. Content validity analysis revealed 4 items not appropriate, 1 item with irrelevant calibration, and omission of some treatment widely used in pwMS. Internal consistency was appreciated with Cronbach's alpha = 0.48 IC 95% [0.31; 0.6]. CONCLUSION NBD questionnaire lacks content validity and presents a weak internal consistency in pwMS. A specific questionnaire is therefore required in pwMS to optimize bowel management and follow-up.

Abstract
Multiple sclerosis is a chronic disease that may lead to different types of symptoms and disabilities. with the better quality of life and decreased disability due to early diagnosis and the availability of disease-modifying therapies (DMTs), the treating physician is increasingly asked to counsel patients on its effects on fertility and reproduction. In particular, reproductive issues are still scarcely studied and discussed in men. Among the still open questions are the following: (a) Does multiple sclerosis cause infertility per sè? (b) Is multiple sclerosis correlated with conditions that increase the risk of infertility? (c) Do DMTs or other therapies for multiple sclerosis impact gonadal function in men? The aim of this review is to provide an overview on the available literature data about the reproductive issues unique to men with multiple sclerosis, underlining the numerous areas where evidence is lacking and, therefore, the priorities for future research.

Abstract
BACKGROUND: Anorectal dysfunction (ARD), especially bowel incontinence, frequently compromises the quality of life in multiple sclerosis (MS) patients. The effect of rehabilitation procedures has not been clearly established. OBJECTIVE: To determine the effect of an individualized rehabilitation approach on bowel incontinence and anorectal pressures. METHODS: MS patients with ARD underwent 6-months of individually targeted biofeedback rehabilitation. High resolution anorectal manometry (HRAM) and St. Mark’s Fecal Incontinence Scores (SMIS) were completed prior to rehabilitation, after 10 weeks of supervised physiotherapy, and after 3 months of self-treatment. RESULTS: Ten patients (50%) completed the study. Repeated measures analysis of variance (ANOVA) demonstrated significant improvement in the SMIS questionnaire over time [14.00 baseline vs. 9.70 after supervised physiotherapy vs. 9.30 after self-treatment (p = 0.005)]. No significant improvements over time were noted in any HRAM readings: maximal pressure [49.85 mmHg baseline vs. 57.60 after supervised physiotherapy vs. 60.88 after self-treatment (p = 0.58)], pressure endurance [36.41 vs. 46.89 vs. 49.95 (p = 0.53)], resting pressure [55.83, vs 52.69 vs. 51.84 (p = 0.704)], or area under the curve [230.0 vs. 520.8 vs. 501.9 (p = 0.16)]. CONCLUSIONS: The proposed individualized rehabilitation program supports a positive overall effect on anorectal dysfunction in MS patients.

Abstract
Schizophrenia is a neuropsychiatric disorder characterized by various symptoms including autonomic imbalance. These disturbances involve almost all autonomic functions and might contribute to poor medication compliance, worsened quality of life and increased mortality. Therefore, it has a great importance to find a potential therapeutic solution to improve the autonomic disturbances. The altered level of kynurenines (e.g., kynurenic acid), as tryptophan metabolites, is almost the most consistently found biochemical abnormality in schizophrenia. Kynurenic acid influences different types of receptors, most of them involved in the pathophysiology of schizophrenia. Only few data suggest that kynurenines might have effects on multiple autonomic functions. Publications so far have discussed the implication of kynurenines and the alteration of the autonomic nervous system in schizophrenia independently from each other. Thus, the coupling between them has not yet been addressed in schizophrenia, although their direct common points, potential interfaces indicate the consideration of their interaction. The present review gathers autonomic disturbances, the impaired kynurenine pathway in schizophrenia, and the effects of kynurenine pathway on autonomic functions. In the last part of the review, the potential interaction between the two systems in schizophrenia, and the possible therapeutic options are discussed.

Abstract
Multiple sclerosis (MS) is an inflammatory neurodegenerative disorder manifesting as gradual or progressive loss of neurological functions. Most patients present with relapsing-remitting disease courses. Extensive research over recent decades has expounded our insights into the presentations and diagnostic features of MS. Groups of genetic diseases, CADASIL and leukodystrophies, for example, have been frequently misdiagnosed with MS due to some overlapping clinical and radiological features. The delayed identification of these diseases in late adulthood can lead to severe neurological complications. Herein we discuss genetic diseases that have the potential to mimic multiple sclerosis, with highlights on clinical identification and practicing pearls that may aid physicians in recognizing MS-mimics with genetic background in clinical settings.

Abstract
PURPOSE To analyze cardiovascular safety of mirabegron in patients with spinal cord injury (SCI)- and multiple sclerosis (MS)-induced neurogenic detrusor overactivity (NDO) in a prospective, randomized, double-blind, placebo-controlled study. METHODS Seventy-eight patients were enrolled into the study, and 66 of them were included into the final analysis. In 49 (74.2%), NDO developed due to suprasacral SCI, 17 (25.8%) suffered from NDO due to MS. Eleven patients were previously treated for hypertension and one for arrhythmia. All study participants received placebo for 2 weeks run-in period. Subsequently, eligible subjects were randomized for 4 weeks of active treatment with mirabegron 50 mg once daily (Group A; n = 32) or placebo (Group B; n = 34). Data from resting electrocardiography (ECG), 24-h ECG and blood pressure monitoring, and echocardiographic examination, were used for cardiovascular safety assessment. All reported variables were evaluated at time of randomization and at the end of the study. Longitudinal changes of variables within the groups and differences between the groups were assessed using nonparametric Kruskal-Wallis test, and p ≤ 0.05 was considered statistically significant. RESULTS No statistically significant longitudinal changes were found in safety variables, except for prolongation of QT interval in placebo group (p = 0.0328) recorded by resting ECG. No significant difference between the Groups A and B, in any of the variables, was observed. A single cardiovascular study drug-related adverse event was recorded in a patient with cervical SCI (3.13%). CONCLUSIONS Our results suggest that mirabegron can be safely used in the treatment of patients with SCI- and MS-induced NDO.

Evidence of Autonomic Dysfunction in Patients with Relapsing-Remitting Multiple Sclerosis: Heart Rate Variability and Cardiovascular Parameters. PATHOPHYSIOLOGY 2021; 28:10-19. [PMID: 35366266 PMCID: PMC8830440 DOI: 10.3390/pathophysiology28010002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 12/26/2020] [Accepted: 12/27/2020] [Indexed: 12/20/2022] Open
Abstract
This study was aimed at evaluation of autonomic dysfunction in patients with multiple sclerosis (MS) by means of time- and frequency-domain parameters of heart rate variability (HRV) and conventional cardiovascular tests (deep breathing (DB) and active orthostatic test (AOT)). The study group enrolled 32 patients with the relapsing-remitting MS (17 m, 15 f, aged 29 ± 4.9 years, disease duration 4.2 ± 2.7 years, EDSS scores less than 3.0 and 26 subjects in good health (HC, 15 m, 11 f, aged 30.1 ± 2.7 years). In the MS group, at rest the variability of heart rate was decreased in comparison to the HC group seen by time- (SDNN, RMSSD, pNN50, CV, p < 0.01) and frequency-domain (TP, HF, LF, p < 0.05) parameters, what was indicative of the general decrease of the autonomic neurogenic control of the heart rate, both sympathetic and parasympathetic. The functional tests (DB and AOT) showed reduced cardiovascular reactivity in the MS group. Additionally, the cardio-respiratory synchronization was impaired in the MS group at rest and DB. The severity of HRV deficit in the MS group correlated with the activity of MS. In conclusion, the comprehensive assessment of time- and frequency-domain HRV parameters studied with functional tests provides better insight to understanding autonomic dysfunction in subjects with relapsing-remitting MS.

Abstract
Selective sympathetic and parasympathetic pathways that act on target organs represent the terminal actors in the neurobiology of homeostasis and often become compromised during a range of neurodegenerative and traumatic disorders. Here, we delineate several neurotransmitter and neuromodulator phenotypes found in diverse parasympathetic and sympathetic ganglia in humans and rodent species. The comparative approach reveals evolutionarily conserved and non-conserved phenotypic marker constellations. A developmental analysis examining the acquisition of selected neurotransmitter properties has provided a detailed, but still incomplete, understanding of the origins of a set of noradrenergic and cholinergic sympathetic neuron populations, found in the cervical and trunk region. A corresponding analysis examining cholinergic and nitrergic parasympathetic neurons in the head, and a range of pelvic neuron populations, with noradrenergic, cholinergic, nitrergic, and mixed transmitter phenotypes, remains open. Of particular interest are the molecular mechanisms and nuclear processes that are responsible for the correlated expression of the various genes required to achieve the noradrenergic phenotype, the segregation of cholinergic locus gene expression, and the regulation of genes that are necessary to generate a nitrergic phenotype. Unraveling the neuron population-specific expression of adhesion molecules, which are involved in axonal outgrowth, pathway selection, and synaptic organization, will advance the study of target-selective autonomic pathway generation.

Abstract
AbstractDisorders of sudomotor function are common and diverse in their presentations. Hyperhidrosis or hypohidrosis in generalized or regional neuroanatomical patterns can provide clues to neurologic localization and inform neurologic diagnosis. Conditions that impair sudomotor function include small fiber peripheral neuropathy, sudomotor neuropathy, myelopathy, α-synucleinopathies, autoimmune autonomic ganglionopathy, antibody-mediated hyperexcitability syndromes, and a host of medications. Particularly relevant to neurologic practice is the detection of postganglionic sudomotor deficits as a diagnostic marker of small fiber neuropathies. Extensive anhidrosis is important to recognize, as it not only correlates with symptoms of heat intolerance but may also place the patient at risk for heat stroke when under conditions of heat stress. Methods for assessing sudomotor dysfunction include the thermoregulatory sweat test, the quantitative sudomotor axon reflex test, silicone impressions, and the sympathetic skin response.

Abstract
Multiple sclerosis (MS) is the most common chronic neurological disorder in young adults, with numerous potential effects on neurologic function. Sexual dysfunction (SD) is a common and very stressful one in persons with MS and represents a significant burden of disease. It has been shown that proportion of SD in MS is greater than in other neurological diseases, and almost five times higher than in the general population. Since there is no consistent definition in the literature for the diagnosis of SD, various studies reported a prevalence of SD of 40-80% in women and 50-90% in men with MS. The nature of sexual changes in this chronic illness is best defined as primary, secondary, and tertiary. Recently, it has been emphasized that detailed sexual history is crucial for all SD assessments and diagnoses. Committee 3 of the international consultation on sexual medicine suggested an updating algorithm for diagnostic evaluation of SD in both genders, with specific recommendations related to sexual history taking and diagnostic evaluation. Because treatments and preventive strategies might manage SD, it is necessary to increase the focus on these aspects of the disease when counselling patients. Management of SD should be comprehensive because the symptoms could be somatic, psychological, or related to relationship problems.

Abstract
BACKGROUND Evaluating the usefulness of treatment requires a direct measurement of the health-related quality of life (QOL). Therefore, this study was carried out aiming to determine the QOL of patients with MS and voiding dysfunction. METHODS This cross-sectional study was carried out using multi-stage random cluster sampling method on 602 patients with MS in Isfahan, Iran. All data were collected through interviews using standard questionnaires including International Prostate Symptom Score (IPSS), and the Multiple Sclerosis Quality of Life-54 (MSQOL-54). Data were analyzed using descriptive and inferential statistical tests. RESULTS The prevalence rate of mixed, irritative, and obstructive urinary symptoms was 52.2, 25.5, and 6.5%, respectively. The mixed symptom had the highest prevalence among men and women with rates of 56.5 and 51.1%, respectively. The prevalence of irritative and obstructive symptoms was, respectively, higher and statistically significant among women alone and men alone (P < 0.05). The prevalence of irritative symptoms was higher among patients with MS, EDSS score ≤ 3, disease duration of less than 5 years, and with clinically isolated syndrome. In addition, the prevalence of mixed symptoms was higher among patients with MS of over 30 years of age with a Pre-high school degree, severe disability, disease duration of over 10 years, and progressive MS; the difference was statistically significant (P < 0.05). There was a difference in the combined dimensions of physical and mental health of QOL between the two groups with and without urinary symptoms (P < 0.05). Logistic regression analysis revealed that there was a higher probability of a urinary problems among patients with MS and high age [3.273 (1.083-9.860); P = 0.035]. CONCLUSIONS Mixed urinary symptoms are highly prevalent among MS patients and affect QOL dimensions. In order to improve QOL, more attention and focus should be paid to urinary problems in MS patients.

Abstract
Background Most patients with multiple sclerosis (MS) suffer from bladder dysfunction during the course of the disease. This study was conducted to examine the prevalence of these complications among patients with MS. Methods This cross-sectional study was performed on 602 patients with MS who referred to the neurology clinics of Kashani and Alzahra Hospitals affiliated to Isfahan University of Medical Sciences, Isfahan, Iran. Multistage random cluster sampling was performed and the informed consent form was signed by the subjects. Then, all the data were collected through interviews using the Lower Urinary Tract Symptom Score (LUTSS) developed in accordance with the definitions presented by the International Continence Society (ICS) and the International Prostate Symptom Score (I-PSS) and DASS-21 questionnaire. The data were analyzed using descriptive and inferential statistical tests in SPSS. Results The prevalence rate of lower urinary tract symptoms (LUTS) was 87.6% among all the subjects, with a similar rate among women (88.0%) and men (86.0%). There was a significant difference between men and women in terms of the prevalence of stress urinary incontinence (SUI), intermittent urine flow, hesitancy, straining, and dribbling (P < 0.050). There was no significant difference between women and men in terms of the prevalence of other symptoms (P > 0.050). A significant difference was observed in the degree of LUTS with age, marital status, marriage duration, education, illness duration, clinical course, disability, anxiety, depression, and stress (P< 0.05). Moreover, logistic regression analysis revealed that there was a higher probability of a urinary problems among patients with MS and a high EDSS score [0.67 (0.507–0.903), P = 0.008]. Conclusions A high prevalence of LUTS was found among patients with MS. There was a higher probability of a urinary tract problem among patients with MS and a high EDSS score. Therefore, it is recommended that the health system take the necessary measures regarding timely detection and treatment of LUTS among these patients in order to prevent secondary outcomes and improve the quality of life (QOL) of patients with MS.

Mult Scler Relat Disord 2019; 34:150-157. [PMID: 31295724 DOI: 10.1016/j.msard.2019.06.031] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 06/25/2019] [Accepted: 06/26/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND Although relatively rare among pediatric patients, acquired demyelinating syndromes of the central nervous system (ADS) is a potentially disabling condition that warrants hospitalization and long-term follow-up. As such, a better understanding of the epidemiology and hospital utilization for this condition could provide critical information for health care planning and resource allocation. OBJECTIVE To evaluate the trends of hospital utilization and resource use associated with pediatric ADS in the US. METHOD We conducted a serial cross-sectional trend analysis with complex sampling and weighting using nationally representative hospital discharge records, from the Kids´ Inpatient Database (KID), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality coded with International Classification of Diseases (Healthcare Cost and Utilization Project (HCUP) 2018), Ninth Revision (ICD-9-CM) for the years 2003, 2006, 2009, and 2012. We also conducted a cross-sectional study for the KID2016 dataset coded with ICD10-CM to estimate the pediatric ADS-related hospital utilization for the year. EXCLUDING TRANSFERRING DISCHARGES: we evaluated the discharge records for those aged 0 to 19 years diagnosed with any of ADS of central nervous systems including multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), acute disseminated encephalomyelitis (ADEM), optic neuritis (ON), transverse myelitis (TM) and demyelinating disease not specified (DDNS). For the trend analysis, we used variance-weighted regression and Poisson regression for the annual hospitalization rate, total hospital charges and hospital days associated with the ADS hospitalizations for the year 2003 to 2012. RESULTS We estimated a total of 1,292 ADS-related hospitalizations (95%CI: 1127-1,458) in 2003, 2104 hospitalizations (95%CI: 1823-2385) in 2006, 2851 hospitalizations (95%CI: 2499-3203) in 2009, and 3501 hospitalizations (95%CI: 3058-3945) in 2012 among those aged 19 years or younger with diagnoses of ADS. There was an increase in the proportion of the inpatient hospital cost attributed to ADS from 0.06% in 2003 to 0.20% in 2012. The annual hospitalization rates relative to pediatric ADS were 1.59/100,000 (95%CI: 1.51-1.68) in 2003 and 4.21/100,000 (95%CI: 4.07-4.35) in 2012. In the cross-sectional analysis for the year 2016 coded by ICD10-CM, the number of pediatric ADS related hospitalizations were 4,568, constituting 0.30% of the total pediatric hospitalization cost. The annual hospitalization rate for the year 2016 was estimated to be 5.51/100,000. CONCLUSION Hospital utilization by pediatric patients with ADS increased during the period 2003 through 2012. The cross-sectional analysis for the year 2016 indicated that the trend could be ongoing, although the direct comparison was not feasible due to the changes in the coding system of the dataset from ICD9-CM to ICD10-CM. Although relatively rare, pediatric ADS warrant long-term follow-ups and hospitalizations, impacting the developmental trajectory of the affected children and the lives of their family members. Th potentially increasing trend of pediatric ADS hospital utilization should be acknowledged when allocating and planning future resources and supporting programs.

Abstract
BACKGROUND Between 50% and 80% of people with multiple sclerosis (PwMS) experience neurogenic bowel dysfunction (NBD) (i.e. constipation and faecal incontinence) that affects quality of life and can lead to hospitalisation. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of abdominal massage plus advice on bowel symptoms on PwMS compared with advice only. A process evaluation investigated the factors that affected the clinical effectiveness and possible implementation of the different treatments. DESIGN A randomised controlled trial with process evaluation and health economic components. Outcome analysis was undertaken blind. SETTING The trial took place in 12 UK hospitals. PARTICIPANTS PwMS who had 'bothersome' NBD. INTERVENTION Following individualised training, abdominal massage was undertaken daily for 6 weeks (intervention group). Advice on good bowel management as per the Multiple Sclerosis Society advice booklet was provided to both groups. All participants received weekly telephone calls from the research nurse. MAIN OUTCOME MEASURES The primary outcome was the difference between the intervention and control groups in change in the NBD score from baseline to week 24. Secondary outcomes were measured via a bowel diary, adherence diary, the Constipation Scoring System, patient resource questionnaire and the EuroQol-5 Dimensions, five-level version (EQ-5D-5L). RESULTS A total of 191 participants were finalised, 189 of whom were randomised (two participants were finalised in error) (control group, n = 99; intervention group, n = 90) and an intention-to-treat analysis was performed. The mean age was 52 years (standard deviation 10.83 years), 81% (n = 154) were female and 11% (n = 21) were wheelchair dependent. Fifteen participants from the intervention group and five from the control group were lost to follow-up. The change in NBD score by week 24 demonstrated no significant difference between groups [mean difference total score -1.64, 95% confidence interval (CI) -3.32 to 0.04; p = 0.0558]; there was a significant difference between groups in the change in the frequency of stool evacuation per week (mean difference 0.62, 95% CI 0.03 to 1.21; p = 0.039) and in the number of times per week that participants felt that they emptied their bowels completely (mean difference 1.08, 95% CI 0.41 to 1.76; p = 0.002), in favour of the intervention group. Of participant interviewees, 75% reported benefits, for example less difficulty passing stool, more complete evacuations, less bloated, improved appetite, and 85% continued with the massage. A cost-utility analysis conducted from a NHS and patient cost perspective found in the imputed sample with bootstrapping a mean incremental outcome effect of the intervention relative to usual care of -0.002 quality-adjusted life-years (QALYs) (95% CI -0.029 to 0.027 QALYs). In the same imputed sample with bootstrapping, the mean incremental cost effect of the intervention relative to usual care was £56.50 (95% CI -£372.62 to £415.68). No adverse events were reported. Limitations include unequal randomisation, dropout and the possibility of ineffective massage technique. CONCLUSION The increment in the primary outcome favoured the intervention group, but it was small and not statistically significant. The economic analysis identified that the intervention was dominated by the control group. Given the small improvement in the primary outcome, but not in terms of QALYs, a low-cost version of the intervention might be considered worthwhile by some patients. FUTURE WORK Research is required to establish possible mechanisms of action and modes of massage delivery. TRIAL REGISTRATION Current Controlled Trials ISRCTN85007023 and NCT03166007.

Abstract
The role of stress effector systems in the initiation and progression of multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), the most commonly used experimental model of MS, has strongly been suggested. To corroborate this notion, alterations in activity of the sympathoadrenal and sympathoneural axes of sympathoadrenal system (a major communication pathway between the central nervous system and the immune system), mirrored in altered release of their end-point mediators (adrenaline and noradrenaline, respectively), are shown to precede (in MS) and/or occur during development of MS and EAE in response to immune cell activation (in early phase of disease) and disease-related damage of sympathoadrenal system neurons and their projections (in late phase of disease). To add to the complexity, innate immunity cells and T-lymphocytes synthesize noradrenaline that may be implicated in a local autocrine/paracrine self-amplifying feed-forward loop to enhance myeloid-cell synthesis of proinflammatory cytokines and inflammatory injury. Furthermore, experimental manipulations targeting noradrenaline/adrenaline action are shown to influence clinical outcome of EAE, in a disease phase-specific manner. This is partly related to the fact that virtually all types of cells involved in the instigation and progression of autoimmune inflammation and target tissue damage in EAE/MS express functional adrenoceptors. Although catecholamines exert majority of immunomodulatory effects through β2-adrenoceptor, a role for α-adrenoceptors in EAE pathogenesis has also been indicated. In this review, we summarize all aforementioned aspects of immunopathogenetic action of catecholamines in EAE/MS as possibly important for designing new strategies targeting their action to prevent/mitigate autoimmune neuroinflammation and tissue damage.

Abstract
BACKGROUND People with multiple sclerosis (PwMS) often develop an autonomic dysfunction (AD), which onset should be assessed early at a subclinical level, as it may interfere with pharmacological treatments and exercise. OBJECTIVE To evaluate basal cardiac autonomic tone, its modulations during sit-to-stand, sub-maximal exercise and recovery in PwMS without clinical overt AD and its relationships with fatigue perception. METHODS Twenty-three PwMS (55 ± 8 yrs [mean ± SD]; EDSS score 5.7 ± 1.3) and 20 age-matched healthy controls (HC; 55 ± 8yrs) were enrolled. ECG was digitally acquired during:1) sitting at rest (low sympathetic activation); 2) standing (light sympathetic activation); and 3) during light exercise (moderate sympathetic activation) and recovery. Parasympathetic and sympatho-vagal parameters of heart rate (HR) variability in time and frequency domains were calculated from beat series. RESULTS HR was slightly but not significantly higher in PwMS compared to HC in all experimental conditions. Parasympathetic indexes were significantly lower (p < 0.05) in PwMS compared to HC during baseline sitting and post-exercise recovery, whereas sympathovagal parameters were similar in both groups. No correlation between autonomic tone and perceived fatigue was observed. CONCLUSION Parasympathetic tone appears to be impaired in PwMS basal and post-exercise conditions, but not during postural challenge and exercise. In addition, AD does not affect perceived fatigue.

Abstract
OBJECTIVES To determine the prevalence and severity of neuropathic pain, sudomotor dysfunction and abnormal vibration perception in patients with MS. METHODS 73 patients with MS and 32 age-matched healthy controls underwent assessment of expanded disability severity score (EDSS), DN4 to assess neuropathic pain, electrochemical skin conductance (ESC) to assess sudomotor function and vibration perception threshold (VPT). RESULTS Patients with MS had a higher DN4 score (p < 0.001) with 14% fulfilling the criteria for neuropathic pain elevated VPT (p < 0.001) and lower ESC on the feet (p < 0.001) and hands (p < 0.001) compared to control participants. ESC on the feet (32% of MS patients) and hands (30% of MS patients) were lower, and DN4 (77% of MS patients) and VPT (64% of MS patients) were greater than 2SD of the healthy control values, respectively. EDSS correlated with the number of relapses (r = 0.564, p < 0.001), VPT (r = -0.457, < 0.001) and ESC on the feet (r = -0.268, p = 0.023). CONCLUSIONS Patients with multiple sclerosis have evidence of sudomotor dysfunction and elevated vibration perception, which were associated with neurological disability from MS.

Costa J, Moreira A, Moreira P, Delgado L, Silva D. Effects of weight changes in the autonomic nervous system: A systematic review and meta-analysis. Clin Nutr 2018; 38:110-126. [PMID: 29395374 DOI: 10.1016/j.clnu.2018.01.006] [Citation(s) in RCA: 46] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2017] [Revised: 12/28/2017] [Accepted: 01/02/2018] [Indexed: 12/22/2022]
Abstract
BACKGROUND Obesity has been linked to autonomic dysfunction, which is thought to be one of the main contributors for hypertension, cardiac remodelling and death. Exercise and diet-based weight loss are the mainstay therapy for obesity, but there is a paucity of data regarding the effect of weight changes in autonomic nervous system (ANS) activity. OBJECTIVE To describe the impact of weight changes in autonomic nervous system. METHODS A systematic literature search of four biomedical databases was performed evaluating effects of weight changes, thorough diet and/or exercise-based interventions, in the following ANS outcomes: heart rate variability, namely low frequency (LF)/high frequency (HF) ratio (LF/HF ratio), normalized units of LF (LFnu) and HF (HFnu), muscle sympathetic nerve activity (MSNA), noradrenaline spillover rate (NA-SR), standard deviation of normal-to-normal intervals (SDNN), root mean square of successive differences (RMSSD), baroreflex sensitivity and pupillometry. Quality appraisal was performed using the GRADE methodology and, where fitting, studies with comparable outcomes were pooled for meta-analysis. RESULTS Twenty-seven studies - 7 controlled clinical trials and 20 observational studies - were included. Weight gain was reported in 4 studies and weight loss in all the other studies. Interventions inducing weight changes included: hypocaloric or hypercaloric diets, exercise (strength, endurance or aerobic training) and hypocaloric diet coupled with exercise programs. Most studies which resulted in weight loss reported decreases in LF/HF ratio, LFnu, MSNA burst frequency and incidence, NA-SR, and an increase of baroreflex sensitivity, HF, HFnu and RMSSD, pointing to a parasympathetic nervous system activation. Meta-analysis regarding weight loss interventions showed a significant pooled effect size (95% CI) with a decreased of MSNA burst frequency -5.09 (-8.42, -1.75), MSNA incidence -6.66 (-12.40, -0.62), however this was not significant for SDNN 14.32 (-4.31, 32.96). Weight gain was associated with an increase in LF/HF, LFnu, MSNA burst frequency and incidence. The weight loss effects were potentiated by the association of hypocaloric diet with exercise. Nevertheless, weight changes effects in these outcomes were based in low or very low quality of evidence. CONCLUSIONS Diet and exercise based weight loss appears to increase parasympathetic and decrease sympathetic activity, the opposing effects being observed with weight gain. These findings are not uniformly reported in the literature, possibly due to differences in study design, methodology, characteristics of the participants and techniques used to estimate autonomic nervous activity.

Abstract
Orthostatic challenge produced by upright posture may lead to syncope if the cardiovascular system is unable to maintain adequate brain perfusion. This review outlines orthostatic intolerance related to the aging process, long-term bedrest confinement, drugs, and disease. Aging-associated illness or injury due to falls often leads to hospitalization. Older patients spend up to 83% of hospital admission lying in bed and thus the consequences of bedrest confinement such as physiological deconditioning, functional decline, and orthostatic intolerance represent a central challenge in the care of the vulnerable older population. This review examines current scientific knowledge regarding orthostatic intolerance and how it comes about and provides a framework for understanding of (patho-) physiological concepts of cardiovascular (in-) stability in ambulatory and bedrest confined senior citizens as well as in individuals with disease conditions [e.g., orthostatic intolerance in patients with diabetes mellitus, multiple sclerosis, Parkinson's, spinal cord injury (SCI)] or those on multiple medications (polypharmacy). Understanding these aspects, along with cardio-postural interactions, is particularly important as blood pressure destabilization leading to orthostatic intolerance affects 3-4% of the general population, and in 4 out of 10 cases the exact cause remains elusive. Reviewed also are countermeasures to orthostatic intolerance such as exercise, water drinking, mental arithmetic, cognitive training, and respiration training in SCI patients. We speculate that optimally applied countermeasures such as mental challenge maintain sympathetic activity, and improve venous return, stroke volume, and consequently, blood pressure during upright standing. Finally, this paper emphasizes the importance of an active life style in old age and why early re-mobilization following bedrest confinement or bedrest is crucial in preventing orthostatic intolerance, falls and falls-related injuries in older persons.

Abstract
BACKGROUND Cognitive fatigue and autonomic abnormalities are frequent symptoms in MS. Our model of MS-related fatigue assumes a shared neural network for cognitive fatigue and autonomic failures, i.e., aberrant vagus nerve activity induced by inflammatory processes. Therefore, they should occur in common. OBJECTIVE To explore the relationship between cognitive fatigue and autonomic symptoms in MS patients, using self-reported questionnaires. METHODS In 95 MS patients, cognitive fatigue was assessed with the Fatigue Scale for Motor and Cognitive Functions and autonomic abnormalities with the Composite Autonomic Symptom Scale-31 (COMPASS-31). We used exploratory correlational analyses and hierarchical regression analysis, controlling for age, depressive mood, disease status, and disease duration, to analyze the relation between autonomic abnormalities and cognitive fatigue. RESULTS The cognitive fatigue score strongly correlated with the COMPASS-31 score (r = 0.47, p < 0.001). Regression analysis revealed that a model, including the COMPASS-31 domains: pupillomotor, orthostatic intolerance, and bladder, best predict the level of cognitive fatigue (R2 = 0.47, p < 0.001) after forcing the covariates into the model. CONCLUSION In MS patients, cognitive fatigue and autonomic dysfunction share a proportion of variance. This supports our model assuming that fatigue might be explained at least partially by inflammation-induced vagus nerve activity.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to investigate the correlation between the duration of the QTc interval and the brain lesion load at the level of the structures involved in superior autonomic control (insula, cingulate cortex and amygdala-hippocampus) in multiple sclerosis (MS) patients. METHODS Thirty-one consecutive patients with relapsing-remitting MS were recruited. The QT interval was measured manually in all 12 leads by a single blinded observer, with the longest QT value adjusted for heart rate by using the Bazett's formula. All patients performed a brain magnetic resonance imaging (MRI) scan including three-dimensional double inversion recovery and three volumetric fast-field echo sequences. The following MRI measures were obtained: (i) global and regional cortical thickness (CTh); (ii) white matter lesion load volume; (iii) cortical damage blindly assessed by a trained observer who assigned, on the basis of the number of cortical lesions, a score from 0 to 5 for each of the brain areas analysed. RESULTS In all, 16% of the patients had an increased QTc interval. The QTc interval was correlated with disease duration, cortical insular lesion volume and grey matter lesion volume in the three examined areas and inversely correlated with global and insular CTh. CONCLUSIONS An increased QTc interval in patients with MS may have a cerebral origin possibly driven by involvement of the insular cortex. With the recent introduction in clinical practice of treatments with potential cardiac effects such as fingolimod, the recognition of a long QTc interval could be clinically crucial and should encourage appropriate electrocardiographic monitoring in order to prevent the risk of malignant ventricular pro-arrhythmia and iatrogenic sudden death.

Abstract
Over the course of the development of deep brain stimulation (DBS) into a well-established therapy for Parkinson's disease, essential tremor, and dystonia, its utility as a potential treatment for autonomic dysfunction has emerged. Dysfunction of autonomic processes is common in neurological diseases. Depending on the specific target in the brain, DBS has been shown to raise or lower blood pressure, normalize the baroreflex, to alter the caliber of bronchioles, and eliminate hyperhidrosis, all through modulation of the sympathetic nervous system. It has also been shown to improve cortical control of the bladder, directly induce or inhibit the micturition reflex, and to improve deglutition and gastric emptying. In this review, we will attempt to summarize the relevant available studies describing these effects of DBS on autonomic function, which vary greatly in character and magnitude with respect to stimulation target.
