Exploring associations with depressive and anxiety symptoms among Syrian patients with ankylosing spondylitis undergoing biological treatment: A cross-sectional study.

People with ankylosing spondylitis (AS) are vulnerable group to experience mood disorders. It is crucial to identify factors that contribute to depression and anxiety in order to improve outcomes. This study seeks to determine the rates of depression and anxiety in Syrian AS patients, as well as identify potential predictors for these conditions. This cross-sectional study was conducted using convenience sampling at the Biological Treatment Unit of the Rheumatology Department of the Damascus Hospital. Data were collected from face-to-face interviews with patients using validated structural questionnaire. A multivariate linear regression model was used to investigate potential predictive factors of depressive and anxiety symptoms. Of the 103 patients, 49.5% showed clinically significant depressive symptoms, and 36.9 % showed clinically significant anxiety symptoms. Multivariate linear regression indicated that depressive and anxiety symptoms were predicted by job layoff, hip pain, positive history of mental distress, poor quality of life, severe fatigue, and high frequency of sleep disturbance with relatively high explanatory powers. depressive and anxiety symptoms were predicted by disease activity scores but with low explanatory power. This study demonstrated high levels of that depressive and anxiety symptoms among Syrian patients with AS undergoing biological treatment. Poor quality of life, severe fatigue, and high-frequency sleep disturbances are major predictive factors for depressive and anxiety symptoms. Screening for depression and anxiety holds significant importance in the comprehensive management of ankylosing spondylitis even in the context of concurrent biological treatment administration.

[Oncological Rehabilitation for Breast Cancer]. / Onkologische Rehabilitation bei Mammakarzinom.

As a result of increasingly individualized and multimodal therapy, prognosis of breast cancer has improved significantly over the last years. However, multimodal treatment and the use of new medications can lead to a variety of somatic, sometimes new, side effects such as fatigue, polyneuropathy or autoimmune toxicities. This and the oncological diagnosis lead to a high level of psychological distress in the women affected and often to subsequent psychological disorders (sleep/anxiety disorders, depression, ...). Both the diverse complaints after oncological therapy and the increasingly improved overall prognosis underline the importance of multimodal rehabilitation concepts to improve quality of life and successful professional reintegration.In the following, these secondary disorders after breast cancer, their multimodal therapy and their significance for social-medical performance assessment are presented in more detail.

Associations of gender with sexual functioning, loneliness, depression, fatigue and physical function amongst patients suffering from rheumatoid arthritis with a particular focus on methotrexate usage.

There is a lack of knowledge regarding methotrexate (MTX) usage in patients with rheumatoid arthritis (RA) and its possible links with gender, disease characterization and sexual functioning, loneliness, fatigue and depression. We, therefore, investigated the associations of gender with physical function, fatigue, depression, loneliness and sexual functioning with a particular focus on MTX usage. A cross-sectional study design was used. Inclusion criteria were RA diagnosis, age above 18 years and available data on MTX treatment 1 year after diagnosis. Data consisted of responses from validated questionnaires regarding physical function, fatigue, depression, loneliness and sexual functioning combined with evaluations from medical records. Data were analysed with linear regression models comparing numerical outcome measures between male and female patients and between MTX users and MTX non-users. Amongst 286 patients with RA (69 men and 217 women), 67.8% were MTX users 1 year after diagnosis. Comparing women and men, both overall and within subgroups of MTX usage, we found significantly more adverse outcomes for women than men in physical functioning at diagnosis and in sexual function, depression, fatigue and physical functioning at enrolment in the study. Gender differences were also present when comparing MTX users with MTX non-users divided by gender. There were only significant differences in the HAQ and loneliness scores when comparing MTX users with MTX non-users. Women with RA had more negative outcomes measured by the selected PROMs compared to men with RA, both overall and in subgroups of users and non-users of MTX. These findings call for sharpened attention to the importance of gender in the treatment and care of patients with RA, as well as in future clinical research.

Prevalence of fatigue and cognitive impairment after traumatic brain injury.

BACKGROUND: Following traumatic brain injury (TBI) some patients develop lingering comorbid symptoms of fatigue and cognitive impairment. The mild cognitive impairment self-reported by patients is often not detected with neurocognitive tests making it difficult to determine how common and severe these symptoms are in individuals with a history of TBI. This study was conducted to determine the relative prevalence of fatigue and cognitive impairment in individuals with a history of TBI. METHODS: The Fatigue and Altered Cognition Scale (FACs) digital questionnaire was used to assess self-reported fatigue and cognitive impairment. Adults aged 18-70 were digitally recruited for the online anonymous study. Eligible participants provided online consent, demographic data, information about lifetime TBI history, and completed the 20 item FACs questionnaire. RESULTS: A total of 519 qualifying participants completed the online digital study which included 204 participants with a history of TBI of varied cause and severity and 315 with no history of TBI. FACs Total Score was significantly higher in the TBI group (57.7 ± 22.2) compared to non-TBI (39.5 ± 23.9; p<0.0001) indicating more fatigue and cognitive impairment. When stratified by TBI severity, FACs score was significantly higher for all severity including mild (53.9 ± 21.9, p<0.0001), moderate (54.8 ± 24.4, p<0.0001), and severe (59.7 ± 20.9, p<0.0001) TBI. Correlation analysis indicated that more severe TBI was associated with greater symptom severity (p<0.0001, r = 0.3165). Ancillary analysis also suggested that FACs scores may be elevated in participants with prior COVID-19 infection but no history of TBI. CONCLUSIONS: Adults with a history of even mild TBI report significantly greater fatigue and cognitive impairment than those with no history of TBI, and symptoms are more profound with greater TBI severity.

Novel pharmacotherapeutic options for the treatment of postural orthostatic tachycardia syndrome.

INTRODUCTION: Postural tachycardia syndrome (POTS) is a disorder characterized by a constellation of symptoms including lightheadedness, fatigue, and palpitations when upright, associated with an increase in the heart rate (HR) of > 30 beats per minute when changing from a lying down to standing position or head-up tilt position and not associated with orthostatic hypotension. The causes as well as the management of POTS are not quite fully understood. AREAS COVERED: We performed a literature review on the diagnosis and management of POTS, and this article includes an overview of novel pharmacotherapeutic options for the treatment of (POTS), although an effective treatment has not been established. EXPERT OPINION: POTS is a clinical syndrome characterized by a constellation of symptoms that are nonspecific. No single etiology or unified hypothesis could be identified. In fact, multiple pathophysiological mechanisms have been proposed, and none of the suggested medications have been approved by the FDA for this indication. Further understanding of the autonomic nervous system and its adjustment to standing position is needed to provide better management strategies.

The association of fatigue severity with pain level, obesity indices and functional performances in women with knee osteoarthritis.

INTRODUCTION: Knee osteoarthritis is most common among women with obesity. It may lead to physical inactivity that, in turn, causes fatigue or lack of physical enthusiasm to perform meaningful daily activities. Hence, this study aimed to examine whether pain level, obesity indices and functional performances are associated with fatigue severity in women with knee osteoarthritis (KOA). MATERIALS AND METHODS: This cross-sectional study recruited women referred to physiotherapy to manage OA. The measurements included fatigue severity (fatigue severity scale); pain level (numerical rating scale); obesity indices (body mass index, fat %, waist circumference); functional performances (upper limb strength, lower limb strength, mobility, exercise capacity and quality of life). A simple linear regression analysis was used to determine which independent variable may be associated with fatigue severity. RESULTS: Ninety-six women with unilateral KOA participated in this study (Mean age, 55.70, Standard Deviation, SD 6.90) years; Mean fatigue severity, 34.51, SD 14.03). The simple linear regression analysis showed that pain level (ß=4.089, p<0.001), fat % (ß=0.825, p<0.001) and QoL (ß=0.304, p<0.001) were significantly associated with fatigue. After controlling for pain level, only fat % was significantly associated with fatigue (ß=0.581, p=0.005). CONCLUSION: Pain level, fat %, and QoL appear to be associated with fatigue severity in women with KOA. In addition, pain symptoms may interact with factors associated with fatigue severity.

A pro-inflammatory diet is associated with long-term depression and anxiety levels but not fatigue in people with multiple sclerosis.

BACKGROUND: Multiple sclerosis is characterised by acute and chronic inflammation in the CNS. Diet may influence inflammation, and therefore MS outcomes. OBJECTIVE: To determine whether the Dietary Inflammatory Index (DII®)) is associated with depression, anxiety, and fatigue in a prospective cohort of people with MS. METHODS: People with a first clinical diagnosis of demyelination were followed over 10 years (n=223). DII and energy-adjusted DII (E-DIITM) scores were calculated from the dietary intake in the preceding 12 months measured by food frequency questionnaire. Depression and anxiety were assessed by the Hospital Anxiety and Depression Scale (HADS-A and HADS-D, respectively), and fatigue by the Fatigue Severity Scale. RESULTS: A higher E-DII score was associated with higher levels of depression and anxiety five years later (e.g., highest vs lowest E-DII quartile, HADS-D score: ß=2.23, 95%CI=0.98,3.48, p<0.001; HADS-A score: ß=1.90, 95%CI=0.59,3.21, p<0.001). A cumulative E-DII score was associated with depression (p<0.01) and anxiety (p=0.05) at the 10-year review. No associations were seen for fatigue. CONCLUSION: Our findings suggest that, in people with MS, a more pro-inflammatory diet may long-term adverse impact on depression and anxiety, but not fatigue.

Fear of falling and common symptoms of multiple sclerosis: Physical function, cognition, fatigue, depression, and sleep - A systematic review.

BACKGROUND: Fear of falling (FOF) is a common concern among persons with multiple sclerosis (MS) and affects the performance of their daily living activities. Falls may result in FOF, leading to worsening of symptoms of MS, physical deconditioning, and exposure to future falls. This may trigger a vicious cycle between FOF and falls. A better understanding of the relationship between FOF and symptoms of MS may be helpful to develop a conceptual model to guide fall prevention interventions. OBJECTIVE: To synthesize the correlational and predictive relationships between FOF and common symptoms of MS. METHODS: Databases including PubMed, Embase, Web of Science, Scopus, CINHAL, PsycINFO, and SPORTDiscuss were searched from inception to October 2023. Studies examining correlations and/or predictions between FOF and common MS symptoms that include measures of gait, postural control, fatigue, cognition, pain, sleep, depression, and anxiety were identified by two independent reviewers. Both reviewers also conducted the methodological quality assessment of the included studies. RESULTS: Twenty-three studies with a total of 2819 participants were included in the review. Correlational findings indicated that increased FOF was significantly associated with greater walking deficits (lower gait speed, smaller steps), reduced mobility, and poorer balance. Increased FOF was also significantly correlated with higher cognitive impairments, more fatigue, sleep disturbances, and depression. Decreased gait parameters, reduced balance, lower physical functions, cognitive impairments, and sleep deficits were found as significant predictors of increased FOF. CONCLUSION: Evidence indicates significant correlational and bidirectional predictive relationships exist between FOF and common MS symptoms. A comprehensive conceptual framework accounting for the interaction between FOF and MS symptoms is needed to develop effective falls prevention strategies.

Exploring resting-state EEG oscillations in patients with Neuromyelitis Optica Spectrum Disorder.

BACKGROUND AND OBJECTIVE: Quantitative resting-state electroencephalography (rs-EEG) is a convenient method for characterizing the functional impairments and adaptations of the brain that has been shown to be valuable for assessing many neurological and psychiatric disorders, especially in monitoring disease status and assisting neuromodulation treatment. However, it has not yet been explored in patients with neuromyelitis optica spectrum disorder (NMOSD). This study aimed to investigate the rs-EEG features of NMOSD patients and explore the rs-EEG features related to disease characteristics and complications (such as anxiety, depression, and fatigue). METHODS: A total of 32 NMOSD patients and 20 healthy controls (HCs) were recruited; their demographic and disease information were collected, and their anxiety, depression, and fatigue symptoms were evaluated. The rs-EEG power spectra of all the participants were obtained. After excluding the participants with low-quality rs-EEG data during processing, statistical analysis was conducted based on the clinical information and rs-EEG data of 29 patients and 19 HCs. The rs-EEG power (the mean spectral energy (MSE) of absolute power and relative power in all frequency bands, as well as the specific power for all electrode sites) of NMOSD patients and HCs was compared. Furthermore, correlation analyses were performed between rs-EEG power and other variables for NMOSD patients (including the disease characteristics and complications). RESULTS: The distribution of the rs-EEG power spectra in NMOSD patients was similar to that in HCs. The dominant alpha-peaks shifted significantly towards a lower frequency for patients when compared to HCs. The delta and theta power was significantly increased in the NMOSD group compared to that in the HC group. The alpha oscillation power was found to be significantly negatively associated with the degree of anxiety (reflected by the anxiety subscore of hospital anxiety and depression scale (HADS)) and the degree of depression (reflected by the depression subscore of HADS). The gamma oscillation power was revealed to be significantly positively correlated with the fatigue severity scale (FSS) score, while further analysis indicated that the electrode sites of almost the whole brain region showing correlations with fatigue. Regarding the disease variables, no statistically significant rs-EEG features were related to the main disease features in NMOSD patients. CONCLUSION: The results of this study suggest that the rs-EEG power spectra of NMOSD patients show increased slow oscillations and are potential biomarkers of widespread white matter microstructural damage in NMOSD. Moreover, this study revealed the rs-EEG features associated with anxiety, depression, and fatigue in NMOSD patients, which might help in the evaluation of these complications and the development of neuromodulation treatment. Quantitative rs-EEG analysis may play an important role in the management of NMOSD patients, and future studies are warranted to more comprehensively understand its application value.

Post-polio syndrome is not a dysimmune condition.

BACKGROUND: Poliomyelitis is a global disabling disease affecting 12-20 million of people. Post poliomyelitis syndrome (PPS) may affect up to 80% of polio survivors: increased muscle weakness, pain, fatigue, functional decline. It relies on aging of an impaired neuro-muscular system with ongoing denervation processes. A late involvement of humoral or cellular pro-inflammatory phenomena is also suspected. AIM: To assess the dysimmune hypothesis of PPS by comparing lymphocyte subpopulations and humoral immune factors between PPS patients and controls. DESIGN: Cross-sectional study. SETTING: Montpellier University Hospital. POPULATION: Forty-seven PPS and 27 healthy controls. METHODS: PPS patients and controls were compared on their lymphocyte subpopulations and humoral immune factors (IL-1ß, IL-6, IL-8, IL-17, IL-21, IL-22, IL-23, IFN-γ, TNF-α, GM-CSF, RANTES, MCP1, MIP-3a, IL-10, TGF-ß, IL4, IL13). Patients were further compared according to their dominant clinical symptoms. Sample size guaranteed a power >90% for all comparisons. RESULTS: PPS patients and controls were comparable in gender, age and corpulence. Most patients had lower limb motor sequelae (N.=45, 95.7%), a minority had upper limb motor impairment (N.=16, 34.0%). Forty-five were able to walk (94%), 35/45 with technical aids. The median of the two-minute walking test was 110 meters (interquartile range 55; 132). Eighteen (38%) required help in their daily life. Their quality of life was low (SF36). All described an increased muscular weakness, 40 (85%) a general fatigue, and 39 (83%) muscular or joint pain. Blood count, serum electrolytes, T and B lymphocyte subpopulations and cytokines were comparable between patients and controls, except for creatine phospho kinase that was significantly higher in PPS patients. None of these variables differed between the 20/47 patients whose late main symptoms were pain or fatigue, and other patients. CONCLUSIONS: Our results suggest that PPS is not a dysimmune disease. CLINICAL REHABILITATION IMPACT: Our results do not sustain immunotherapy for PPS. Our work suggest that PPS may be mostly linked to physiological age-related phenomena in a disabled neuromuscular condition. Thus, our results emphasize the role of prevention and elimination of aggravating factors to avoid late functional worsening, and the importance of rehabilitation programs that should be adapted to patients' specific conditions.

Fear of progression, depression, and sleep difficulties in people experiencing endometriosis-pain: A cross-sectional study.

OBJECTIVE: Endometriosis is a chronic condition generally characterised by severe pain. Recent findings demonstrate disproportionately elevated rates of insomnia and fatigue among people with endometriosis, particularly among those with associated pain. Yet there is little understanding of the psychological factors that might contribute to these sleep and fatigue related difficulties. We investigated whether fear of progression and depression interacted with pain to influence fatigue and insomnia among people with endometriosis-related pain. METHODS: A total of 206 individuals with endometriosis were included in this cross-sectional, online survey in January 2022. Participants provided relevant demographics and endometriosis characteristics. The BPI-SF, FoP-Q-SF, DASS-21, CFS and ISI were used to assess pain intensity, fear of progression, depression, fatigue, and insomnia symptoms, respectively. Associations between key variables were assessed with correlations. A path analysis determined whether the relationships between pain and fatigue, and pain and insomnia, depended on levels of fear of progression and depression. RESULTS: Controlling for age, fear of progression was uniquely associated with worse fatigue (ß = 0.348, p < .001) and insomnia (ß = 0.389, p < .001), and moderated the relationship between pain and fatigue (ß = 0.155, p = .009). Specifically, with increasing pain severity, the effects of fear of progression on fatigue were exacerbated. Depression was uniquely associated with fatigue (ß = 0.360, p < .001), but did not elicit any moderation effects. CONCLUSION: These results highlight the role of fear of progression and depression in endometriosis-related fatigue and insomnia, paving the way for future interventions targeting these constructs to be tested.

A group-based transdiagnostic sleep and circadian treatment for major depressive disorder: A randomized controlled trial.

OBJECTIVE: Sleep and circadian disturbance is highly comorbid with a range of psychological disorders, especially major depressive disorder (MDD). In view of the complexity of sleep and circadian problems in MDD, this study aimed to evaluate the efficacy of a group-based transdiagnostic intervention for sleep and circadian dysfunction (TranS-C) for improving depressive symptoms and sleep and circadian functions. METHOD: One hundred fifty-two adults diagnosed with comorbid MDD and sleep and circadian dysfunctions were randomized into TranS-C group treatment (TranS-C; n = 77) or care as usual (CAU; n = 75) control group. The TranS-C group received six weekly 2-hr group sessions of TranS-C, whereas the CAU group continued to receive usual care. Assessments were at baseline, immediate (Week 7), and 12-week (Week 19) posttreatment. Primary and secondary outcomes included depression, anxiety, sleep disturbances, fatigue, quality of life, and functional impairment. RESULTS: The TranS-C group showed significant improvement in depressive symptoms (p < .001, d = 0.84), insomnia severity (p < .001, d = 0.77), sleep disturbances (p < .001, d = 1.15), sleep-related impairment (p < .001, d = 1.22), fatigue (p < .001, d = 1.06), anxiety symptoms (p = .004, d = 0.67), quality of life (p < .001, d = 0.71), and sleep diary-derived parameters (ps < .05, d = 0.12-0.77) relative to the CAU group at immediate posttreatment. These treatment gains remained significant at 12-week follow-up. Significant improvement in functional impairment was also noted at 12-week follow-up. CONCLUSIONS: TranS-C was efficacious and acceptable in alleviating depressive symptoms and sleep and circadian disruptions in adults with MDD. The group format appears to be a low-cost, widely disseminable option to deliver TranS-C. Further research on TranS-C to examine its benefits on other psychiatric disorders is warranted.

Association between cytokines and fatigue in patients with type 1 narcolepsy.

BACKGROUND: Fatigue is a frequent complaint among patients with narcolepsy. Studies have shown that inflammatory cytokines are associated with fatigue in neurological disorders; however, this association has not been identified in patients with type 1 narcolepsy. The purpose of this study was to investigate the potential relationship between cytokines and fatigue in patients with type 1 narcolepsy. METHODS: We investigated the association between 12 inflammatory cytokines and fatigue in 49 patients with type 1 narcolepsy. The Multidimensional Fatigue Inventory-20 was used to assess the fatigue severity. The associations of fatigue were identified using Spearman and Pearson correlation analyses. A linear regression analysis model was used to adjust the confounding factors and evaluate the associations of fatigue. RESULTS: Correlation analysis showed that the plasma interleukin (IL)-2 level (r = 0.409, p = 0.004) was positively correlated with fatigue in patients with narcolepsy type 1. After adjusting for confounding factors, the linear regression model revealed a positive association between the IL-2 level (ß = 1.148, p = 0.04) and fatigue in individuals diagnosed with type 1 narcolepsy. CONCLUSION: IL-2 levels show a positive correlation with fatigue in type 1 narcolepsy, suggesting its potential role in the pathophysiology of fatigue.

Clinical course of multiple sclerosis with comorbid endometriosis: A matched cohort study.

BACKGROUND: Endometriosis (EMS) is pain syndrome in which endometrial tissue grows outside the uterus. EMS is associated with an increased risk of multiple sclerosis (MS), a demyelinating disease of the central nervous system. OBJECTIVE: To characterize clinical phenotypes of a cohort of patients with both EMS and MS compared to a cohort of matched controls with only MS. METHODS: We retrospectively identified patients with EMS and MS at Beth Israel Deaconess Medical Center (BIDMC). We collected data on EMS treatments and analyzed differences in histories of gynecological cancer, smoking, fatigue, anxiety, depression, headache, and neuropathic pain compared to matched controls. We used Wilcoxon signed rank tests for paired samples to compare Expanded Disability Status Scores (EDSS) and timed 25-foot walk values (T25FW). RESULTS: Using a case-control methodology, we found significantly increased EDSS (p < 0.001) and T25FW (p = 0.01) in the EMS-MS group compared to the MS group. More patients in the EMS-MS group had histories of smoking, anxiety, depression, and headaches, while more patients in the MS group had histories of fatigue and neuropathic pain. CONCLUSION: When controlling for age, race, and MS therapy, those with EMS-MS experience more MS disability than controls, suggesting this population requires more monitoring and efficacious treatment.

Prevalence and correlates of fatigue in amyotrophic lateral sclerosis: A systematic review and meta-analysis.

OBJECTIVES: This systematic review and meta-analysis aimed to determine the frequency and correlates of fatigue in patients with amyotrophic lateral sclerosis (ALS). METHODS: Three databases were searched up to 2nd May 2023 to identify studies reporting fatigue frequency in ALS. Studies included had to identify ALS patients through one of ALS diagnostic criteria and measure fatigue by a validated tool with a specific cut-off value. Meta-analysis was conducted using RStudio's "meta" package with a random-effects model. Subgroup analyses and meta-regression explored the relationship between fatigue frequency in ALS and different covariates. RESULTS: Eleven studies, compromising 1072 patients, met the inclusion criteria and were included in our analysis. The pooled frequency of fatigue across all studies was 48% (95% CI = 40% to 57%). Our subgroup analysis based on the ALSFRS-R revealed a higher frequency of fatigue in studies with lower scores (< 30) compared to those with higher scores (≥ 30), with a pooled frequency of 62% (95% CI = 43% to 79%) and 43% (95% CI = 37% to 49%), respectively. Also, the meta-regression analysis showed a significant negative association between fatigue and ALSFRS-R mean (P = 0.02). The included studies reported an association between fatigue and lower functional status and poorer quality of life in patients with ALS. CONCLUSION: Our findings suggest that fatigue is prevalent in almost half of ALS patients and is associated with lower functional status and poorer quality of life, highlighting the importance of assessing and managing fatigue in ALS patients.

Undiagnosed obstructive sleep apnea syndrome as a treatable cause of new-onset sleepiness in some post-COVID patients.

BACKGROUND AND PURPOSE: Infection with COVID-19 can lead to persistent sequelae, such as fatigue, daytime sleepiness or disturbed sleep, that can remain for more than 12 weeks and that are summarized as post-COVID syndrome. The causes remain unclear. The present study investigated the presence of sleep disorders in patients with post-COVID syndrome using polysomnography. METHODS: Thirty-four patients with post-COVID syndrome and new-onset fatigue and sleepiness after a SARS-CoV2 infection underwent polysomnography in accordance with American Association of Sleep Medicine (AASM) standards as part of their clinical workup. Analysis was performed visually based on AASM criteria (scoring manual version 2.6, 2020). RESULTS: Polysomnography revealed a sleep efficiency of <80% in 50% of patients and a mean respiratory disturbance index (RDI) of 9.9 ± 15.4/h. Excluding central apneas, 12 patients (35%) had an RDI of ≥5/h, pointing to obstructive sleep apnea syndrome (OSAS; AASM 2014). Patients with a high RDI were significantly older (p = 0.01) and showed a trend towards a higher body mass index (p = 0.08) than patients with a normal RDI but had no other risk factors for OSAS. Six patients agreed to long-term treatment of their OSAS and all reported discontinuation of daytime symptoms. CONCLUSIONS: Post-COVID symptoms such as daytime sleepiness, fatigue and memory and concentration problems may in part be a result of reduced sleep efficiency and sleep apnea in a relevant percentage of patients. This possibly treatable cause of the symptoms should be kept in mind in patients presenting with post-COVID syndrome.

Long term effects of continuous positive airway pressure treatment of obstructive sleep apnea-hypopnea syndrome in multiple sclerosis patients.

BACKGROUND: Obstructive sleep apnea-hypopnea (OSAH) is common in MS patients and is associated with fatigue. We recently published a randomized, controlled trial (RCT) of active vs sham continuous positive airway pressure (CPAP) treatment in MS patients with fatigue, poor sleep quality, and (OSAH) (Mult Scl J 2022;28:82-92). Our aim was to evaluate the long-term effects of CPAP treatment on fatigue (Fatigue Severity Scale, FSS, primary outcome) and other clinical outcomes in MS patients with OSAH. METHODS: Following the RCT, participants were offered treatment with CPAP and participation in an open label study. Patients were re-evaluated with RCT outcome measures at least 6 months after completion of the RCT. RESULTS: Twenty-eight of 34 (82 %) RCT-completers participated in this study a mean of 2.7 years after the RCT. Sixteen (57 %) patients were treated with CPAP (mean use 5.4 ± 1.0 h/night during the 6 months prior to follow-up visit), while the other 12 patients declined CPAP use and received no other OSAH treatments. Baseline clinical characteristics, including MS related disability and sleep outcomes, were not significantly different between CPAP-treated vs non-CPAP treated patients. Patients using CPAP at follow-up (n = 16) demonstrated significant improvements from RCT baseline in FSS (p = 0.005), Fatigue Scale for Motor and Cognitive Functions (p = 0.008, p = 0.012), Pittsburgh Sleep Quality Index (p = 0.016), Center of Epidemiological Studies-Depression Scale (p = 0.05), and Multiple Sclerosis Quality of Life-54 (MSQOL-54) physical and mental component scores (p = 0.012, p = 0.023), but no improvements in Epworth Sleepiness Scale, Pain Visual Analog Scale, or Expanded Disability Status Scale. Patients not using CPAP (n = 12) had no significant improvements in outcome measures. Using a linear mixed model, FSS (p = 0.03), morning fatigue (p = 0.048), and MSQOL-54 physical component score (p = 0.02) improved significantly in CPAP treated patients compared with non-CPAP treated patients from RCT baseline. CONCLUSION: In this post-RCT open label study, long-term CPAP use was associated with improved fatigue (FSS, our primary outcome) and physical quality of life in MS patients with OSAH.

Associations between patient-reported functional disability and measures of physical ability in juvenile fibromyalgia.

ABSTRACT: Juvenile fibromyalgia (JFM) is a chronic condition characterized by symptoms of pain and fatigue and is associated with sedentary behavior and functional disability. Adults with fibromyalgia exhibit deficits in physical fitness as evidenced by lower aerobic capacity and physical endurance, but it is unknown whether these impairments are apparent in adolescents with JFM. Furthermore, the extent to which functional disability and pain interference relate to measures of physical fitness has not been investigated in a pediatric pain population. During a baseline assessment for a clinical trial, 321 adolescents with juvenile fibromyalgia (M age = 15.14, 85.2% female) completed measures of pain intensity, fatigue, JFM symptom severity, functional disability, and pain interference. They also completed 2 validated fitness tasks: (1) the Harvard step test, which assesses aerobic fitness, and (2) the 6-minute walk test, a simple submaximal test of endurance. We examined associations among self-report measures and fitness assessments using bivariate correlations. We then employed hierarchical regression analyses to determine the unique contributions of physical fitness assessments to self-reported functional disability and pain interference. Results indicated that youth with JFM exhibited deficits in aerobic capacity and physical endurance. However, physical fitness explained negligible variance in functional disability and pain interference beyond that accounted for by pain, fatigue, and JFM symptom severity. Scores on available functional disability measures may reflect perceived difficulties in coping with symptoms during physical tasks rather than actual physical capability. Rigorous and sensitive assessments of physical fitness and endurance are needed to determine whether rehabilitation interventions for pediatric pain improve physical functioning.

Long-term outcomes of paediatric Guillain-Barré syndrome.

AIM: To study long-term sequelae in children with Guillain-Barré syndrome (GBS). METHOD: This was a prospective observational study with children from two French tertiary centres. Data were from clinical and several standardized scales or questionnaires. RESULTS: Fifty-one patients were included with a median follow-up of 6 years 4 months (range 3-20 years) after the acute phase. The sequelae rate was 67% (95% confidence interval [CI] 53-78) and did not vary with time. Most children had minor sequelae (Guillain-Barré Syndrome Disability Score [GBSDS] = 1); only one was unable to run (GBSDS = 2). The most frequent complaints were paraesthesia (43%), pain (35%), and fatigue (31%). The neurological examination was abnormal in 18% of children, autonomy was compromised in 14%, and symptoms of depression occurred in 34%. The factors associated with late-onset sequelae were correlated with severity during the initial phase (i.e. initial GBSDS >4, odds ratio 6.6, 95% CI 1.8-33; p = 0.009). The predictive factors of more severe late-onset conditions were initial severity (p = 0.002) and sex (female patients; p = 0.01). INTERPRETATION: Two-thirds of children with GBS had late-onset sequelae following an episode, often minor, but sometimes with continuing effects on their everyday lives. Particularly affected were those who had severe GBS during the acute phase and who lost the ability to walk. WHAT THIS PAPER ADDS: Two-thirds of children with Guillain-Barré syndrome (GBS) had persistent sequelae. Sequelae were often minor, but daily repercussions of them were sometimes serious. Sequelae were significantly associated with severe GBS during the acute phase.

Insomnia and sleep-disordered breathing in FKRP-related limb-girdle muscular dystrophy R9. The Norwegian LGMDR9 cohort study (2020).

Limb-girdle muscular dystrophy R9 (LGMDR9) is a progressive and disabling genetic muscle disease. Sleep is relevant in the patient care as it impacts on health, functioning, and well-being. LGMDR9 may potentially affect sleep by physical or emotional symptoms, myalgia, or sleep-disordered breathing (SDB) through cardiorespiratory involvement. The objective was to investigate the occurrence of insomnia and unrecognized or untreated SDB in LGMDR9, associated factors, and relationships with fatigue and health-related quality of life (HRQoL). All 90 adults in a Norwegian LGMDR9 cohort received questionnaires on sleep, fatigue, and HRQoL. Forty-nine of them underwent clinical assessments and 26 without mask-based therapy for respiration disorders additionally underwent polysomnography (PSG) and capnometry. Among 77 questionnaire respondents, 31% received mask-based therapy. The prevalence of insomnia was 32% of both those with and without such therapy but was significantly increased in fatigued respondents (54% vs 21%). Insomnia levels correlated inversely with mental HRQoL. Among 26 PSG candidates, an apnea-hypopnea index (AHI) ≥ 5/h was observed in 16/26 subjects (≥ 15/h in 8/26) with median 6.8 obstructive apneas and 0.2 central apneas per hour of sleep. The AHI was related to advancing age and an ejection fraction < 50%. Sleep-related hypoventilation was detected in one subject. Fatigue severity did not correlate with motor function or nocturnal metrics of respiration or sleep but with Maximal Inspiratory Pressure (r = - 0.46). The results indicate that insomnia and SDB are underrecognized comorbidities in LGMDR9 and associated with HRQoL impairment and heart failure, respectively. We propose an increased attention to insomnia and SDB in the interdisciplinary care of LGMDR9. Insomnia and pulmonary function should be examined in fatigued patients.
