Insomnia and sleep-disordered breathing in FKRP-related limb-girdle muscular dystrophy R9. The Norwegian LGMDR9 cohort study (2020). J Neurol 2024; 271:274-288. [PMID: 37695533 PMCID: PMC10770197 DOI: 10.1007/s00415-023-11978-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 08/25/2023] [Accepted: 08/28/2023] [Indexed: 09/12/2023]
Abstract
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.

J Clin Med 2021; 10:jcm10173916. [PMID: 34501362 PMCID: PMC8432053 DOI: 10.3390/jcm10173916] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 08/18/2021] [Accepted: 08/26/2021] [Indexed: 01/04/2023] Open
Abstract
Objectives: Stress is supposed to be linked with a background of multiple sclerosis (MS) and the disease course. Design: The study aimed to assess the level of stress and coping strategies in MS patients within a year of follow-up and to investigate the relationships between these aspects and factors related—or not—to MS. Methods: In 65 patients with MS, the Perceived Stress Scale (PSS-10), Type D Scale (DS14) and Coping Orientations to Problems Experienced (COPE) were performed at baseline and after a year. Baseline PSS-10, DS-14 and COPE scores were analyzed with regard to demographics, MS duration, treatment, indices of disability and self-reported stressful events (SEs). Final PSS-10 and COPE results were analyzed with reference to MS activity and SE within a year of follow-up. Results: Initially, 67% of patients reported a moderate or high level of stress and 31% met Type-D personality criteria. Diverse coping strategies were preferred, most of which were problem-focused. The negative affectivity DS-14 subscore (NEG) was correlated with disability level. Non-health-related SEs were associated with higher PSS-10 and NEG scores. After a year, the mean PSS-10 score decreased, while COPE results did not change significantly. Non-health-related SEs were associated with a higher PSS-10 score and less frequent use of acceptance and humor strategies. Those with an active vs. stable MS course during the follow-up did not differ in terms of PSS-10 and COPE results. Conclusions: MS patients experienced an increased level of stress. No significant relationships were found between stress or coping and MS course within a year. Non-health-related factors affected measures of stress more than MS-related factors.

How Many Maneuvers Should We Do for Maximal Inspiratory and Expiratory Muscle Pressure Testing in Children: A Retrospective Review in Children with Cystic Fibrosis. Lung 2021; 199:213-222.

Abstract
OBJECTIVES Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) could be useful clinical parameters in monitoring many conditions including cystic fibrosis (CF). However, current protocols for undertaking the measurements lack standardization including the number of repeated attempts to achieve best values. We aimed to (a) determine the optimum number of attempts to achieve best MIP/MEP values, and (b) evaluate if the number of attempts is consistent across two different test days. METHODS We analyzed data of a previous randomized controlled trial involving the effect of singing on respiratory muscle strength in 35 children with CF. On two different days (T1, T2) children performed MIP/MEP with at least ten attempts each to achieve < 10% repeatability. RESULTS All children achieved repeatable MIP/MEP values within 10-11 attempts with 24 (68.6%) and 26 (74.3%) of these achieving best values of MIP and MEP, respectively, at attempts 6-11. Median values of the pressures by three, five, eight and all attempts significantly increased with more attempts (all p < 0.05). At T2, 56% required fewer attempts to achieve best values, but 32% required more attempts, indicating that the number of attempts required was inconsistent between test days. CONCLUSION It is likely that at least ten attempts (best two within < 10% variability) is required to achieve best and reliable MIP/MEP in children with CF. A larger sample size in children with CF and various conditions is required to consolidate these findings.

Abstract
Postpolio syndrome (PPS) refers to a group of conditions that are present in patients, years after recovery from initial acute paralytic poliomyelitis. About 15%-80% of 20 million polio survivors worldwide will experience exacerbation of symptoms which typically appear 15-30 years after the resolution of initial poliomyelitis. Symptoms include new muscle weakness, fatigue, myalgia, joint pain, dysphagia, and difficulty breathing. Other reported symptoms include cold intolerance, sleep disorder, dysphonia, loss of stamina, musculoskeletal deformities, cardiovascular disorders, psychosocial problems, and restless legs syndrome. These symptoms are attributed to the superimposed neuronal loss of aging with inflammatory mechanisms, but without any convincing evidence of viral reactivation. Risk factors include female gender, respiratory symptoms, normal aging, permanent disability caused by motor neuron damage, muscle overuse and disuse, aging, and immunologic mechanisms. Hypothyroidism-induced myopathy and fibromyalgia are a differential diagnosis for PPS, and exclusion diagnosis is required as confirmatory criteria for PPS. The symptoms of PPS presented determine the course of management.

Abstract
Respiratory muscle strength is a proven predictor of long-term outcome of neuromuscular disease (NMD), including amyotrophic lateral sclerosis, Duchenne muscular dystrophy, and spinal muscular atrophy. Maximal inspiratory pressure (MIP), a sensitive measure of respiratory muscle strength, one of several useful tests of respiratory muscle strength, is gaining interest as a therapeutic clinical trial endpoint for NMD. In this comprehensive review we investigate the use of MIP as a measure of respiratory muscle strength in clinical trials of therapeutics targeting respiratory muscle, examine the correlation of MIP with survival, quality of life, and other measures of pulmonary function, and outline the role of MIP as a clinically significantly meaningful outcome measure. Our analysis supports the utility of MIP for the early evaluation of respiratory muscle strength, especially of the diaphragm, in patients with NMD and as a surrogate endpoint in clinical trials of therapies for NMD.

Abstract
BACKGROUND Poliomyelitis was before the immunization an important medical problem. Nowadays polio prior patients (PP) suffer from polio sequelae or have developed post-polio-syndrome (PPS) with increasing paresis, pain and fatigue. OBJECTIVES To analyze the medical situation 50 years after acute polio. The degree of paresis was compared between the recovery 1952-1961 and 2012.The prevalence of patients fulfilling the criteria for PPS was estimated. METHOD The study was performed in Italy. Included were PP with rehabilitation after acute polio 1952-1961 and in 2012. During the years PP underwent yearly evaluation. A thorough neurological examination was performed in 2012. A telephone interview with questions concerning pain, paresis, fatigue, walking aids and concomitant diseases was performed in 2012. The patients were divided in two groups, if they fulfilled the criteria for PPS or not. RESULTS Included were 67(94%) patients receiving rehabilitation after acute poliomyelitis and 2012. 78% were walkers, half of the PPS used wheelchair. Eight out of ten suffered from pain. Four out of ten fulfilled the PPS criteria. Pain was slightly more common in PPS. CONCLUSION Female gender, fatigue and wheelchair dependency were significantly more common in PPS while pain was common in both groups.

Abstract
ABSTRACT Post-polio syndrome (PPS) is a condition that affects polio survivors years after recovery from an initial acute attack of the poliomyelitis virus. Most often, polio survivors experience a gradual new weakening in muscles that were previously affected by the polio infection. The actual incidence of cardiovascular diseases (CVDs) in individuals suffering from PPS is not known. However, there is a reason to suspect that individuals with PPS might be at increased risk. Method A search for papers was made in the databases Bireme, Scielo and Pubmed with the following keywords: post polio syndrome, cardiorespiratory and rehabilitation in English, French and Spanish languages. Although we targeted only seek current studies on the topic in question, only the relevant (double-blind, randomized-controlled and consensus articles) were considered. Results and Discussion Certain features of PPS such as generalized fatigue, generalized and specific muscle weakness, joint and/or muscle pain may result in physical inactivity deconditioning obesity and dyslipidemia. Respiratory difficulties are common and may result in hypoxemia. Conclusion Only when evaluated and treated promptly, somE patients can obtain the full benefits of the use of respiratory muscles aids as far as quality of life is concerned.

Abstract
OBJECTIVE To determine if coenzyme Q(10) alleviates fatigue in the late-onset sequelae of poliomyelitis. DESIGN Parallel-group, randomized, placebo-controlled trial. BACKGROUND SETTING Coenzyme Q(10) has been shown to boost muscle energy metabolism in post-polio subjects but it does not promote muscle strength, endurance or function in polio survivors with post-poliomyelitis syndrome. However, the collective increased energy metabolism might contribute to a reduction in post-polio fatigue. PARTICIPANTS Polio survivors from the Australian post-polio networks in Queensland and New South Wales who attribute a moderate to high level of fatigue to their diagnosed late-onset sequelae of poliomyelitis. Those with fatigue-associated comorbidities of diabetes, anaemia, hypothyroidism and fibromyalgia were excluded. METHOD Participants were assigned (1:1), with stratification of those who use energy-saving mobility aids, to receive 100 mg coenzyme Q(10) or matching placebo daily for 60 days. Participants and investigators were blinded to group allocation. Fatigue was assessed by the Multidimensional Assessment of Fatigue as the primary outcome and the Fatigue Severity Scale as secondary outcome. RESULTS Of 103 participants, 54 were assigned to receive coenzyme Q(10) and 49 to receive the placebo. The difference in the mean score reductions between the two groups was not statistically significant for either fatigue measure. Oral supplementation with coenzyme Q(10) was safe and well-tolerated. CONCLUSION A daily dose of 100 mg coenzyme Q(10) for 60 days does not alleviate the fatigue of the late-onset sequelae of poliomyelitis. The registration number for the clinical trial is ACTRN 12612000552886.

Abstract
BACKGROUND Fatigue is a common symptom in post-polio syndrome (PPS) and can have a substantial impact on patients. There is a need for validated questionnaires to assess fatigue in PPS for use in clinical practice and research. The aim with this study was to assess the validity and reliability of the Swedish version of Multidimensional Fatigue Inventory (MFI-20) in patients with PPS using the Rasch model. METHODS A total of 231 patients diagnosed with PPS completed the Swedish MFI-20 questionnaire at post-polio out-patient clinics in Sweden. The mean age of participants was 62 years and 61% were females. Data were tested against assumptions of the Rasch measurement model (i.e. unidimensionality of the scale, good item fit, independency of items and absence of differential item functioning). Reliability was tested with the person separation index (PSI). A transformation of the ordinal total scale scores into an interval scale for use in parametric analysis was performed. Dummy cases with minimum and maximum scoring were used for the transformation table to achieve interval scores between 20 and 100, which are comprehensive limits for the MFI-20 scale. RESULTS An initial Rasch analysis of the full scale with 20 items showed misfit to the Rasch model (p < 0.001). Seven items showed slightly disordered thresholds and person estimates were not significantly improved by rescoring items. Analysis of MFI-20 scale with the 5 MFI-20 subscales as testlets showed good fit with a non-significant x (2) value (p = 0.089). PSI for the testlet solution was 0.86. Local dependency was present in all subscales and fit to the Rasch model was solved with testlets within each subscale. PSI ranged from 0.52 to 0.82 in the subscales. CONCLUSIONS This study shows that the Swedish MFI-20 total scale and subscale scores yield valid and reliable measures of fatigue in persons with post-polio syndrome. The Rasch transformed total scores can be used for parametric statistical analyses in future clinical studies.

Abstract
INTRODUCTION Polio survivors in France are estimated at 50,000. This study aimed at describing their needs from their clinical and vocational conditions. METHOD A retrospective study of our physical and rehabilitation medicine (PRM) consultation activity. RESULTS One hundred and fifteen women/85 men, with a mean age of 51years±14.3 (17 to 82). Paralysis involved only one lower limb in 108 patients, the two lower limbs in 56 patients and only one upper limb in 4. At the time of the first consultation 137 patients had experienced functional worsening. The complaints were pain (105 subjects), fatigue (59) and new paresis (58). Only 25% had retired. Post-polio syndrome criteria were present in 46 subjects (23%). Patients who had contracted poliomyelitis in France (56%) differed from the other subjects with regard to age (58.4 versus 41.5), professional status and frequency of PPS (30.9% versus 12.6%). CONCLUSION These polio survivors were not particularly aged and they had often experienced functional worsening. The evolution of their disease shall represent a public health issue over the decades to come.

Abstract
SUMMARY This review evaluates strategies for assessing and treating depression and fatigue for patients diagnosed with motor neuron disease. A summary is given of questionnaire, interview and laboratory methods of assessment, including disease-specific techniques. The unique physical demands of the disease may preclude accurate measurement using generic questionnaire measures and disease-validated measures should be used, where available. There is an urgent need to develop psychological therapies for depression that can cater for the needs of motor neuron disease patients and their carers. Currently, no evidence-based treatment exists for fatigue and further work is warranted to systematically evaluate current evidence and develop novel treatments for this burdensome symptom.

Abstract
Post-polio syndrome (PPS) refers to the clinical deterioration experienced by many polio survivors several decades after their acute illness. The symptoms are new muscle weakness, decreased muscle endurance, fatigue, muscle pain, joint pain, cold intolerance, and this typical clinical entity is reported from different parts of the world. The pathophysiology behind PPS is not fully understood, but a combination of distal degeneration of enlarged motor units caused by increased metabolic demands and the normal aging process, in addition to inflammatory mechanisms, are thought to be involved. There is no diagnostic test for PPS, and the diagnosis is based on a proper clinical workup where all other possible explanations for the new symptoms are ruled out. The basic principle of management of PPS lies in physical activity, individually tailored training programs, and lifestyle modification. Muscle weakness and muscle pain may be helped with specific training programs, in which training in warm water seems to be particularly helpful. Properly fitted orthoses can improve the biomechanical movement pattern and be energy-saving. Fatigue can be relieved with lifestyle changes, assistive devices, and training programs. Respiratory insufficiency can be controlled with noninvasive respiratory aids including biphasic positive pressure ventilators. Pharmacologic agents like prednisone, amantadine, pyridostigmine, and coenzyme Q10 are of no benefit in PPS. Intravenous immunoglobulin (IVIG) has been tried in three studies, all having positive results. IVIG could probably be a therapeutic alternative, but the potential benefit is modest, and some important questions are still unanswered, in particular to which patients this treatment is useful, the dose, and the therapeutic interval.

Abstract
Background Postpoliomyelitis Syndrome (PPS) is a complex of late onset neuromuscular symptoms with new or increased muscle weakness and muscle fatigability as key symptoms. Main clinical complaints are severe fatigue, deterioration in functional abilities and health related quality of life. Rehabilitation management is the mainstay of treatment. Two different therapeutic interventions may be prescribed (1) exercise therapy or (2) cognitive behavioural therapy (CBT). However, the evidence on the effectiveness of both interventions is limited. The primary aim of the FACTS-2-PPS trial is to study the efficacy of exercise therapy and CBT for reducing fatigue and improving activities and quality of life in patients with PPS. Additionally, the working mechanisms, patients' and therapists' expectations of and experiences with both interventions and cost-effectiveness will be evaluated. Methods/Design A multi-centre, single-blinded, randomized controlled trial will be conducted. A sample of 81 severely fatigued patients with PPS will be recruited from 3 different university hospitals and their affiliate rehabilitation centres. Patients will be randomized to one of three groups i.e. (1) exercise therapy + usual care, (2) CBT + usual care, (3) usual care. At baseline, immediately post-intervention and at 3- and 6-months follow-up, fatigue, activities, quality of life and secondary outcomes will be assessed. Costs will be based on a cost questionnaire, and statistical analyses on GEE (generalized estimated equations). Analysis will also consider mechanisms of change during therapy. A responsive evaluation will be conducted to monitor the implementation process and to investigate the perspectives of patients and therapists on both interventions. Discussion A major strength of the FACTS-2-PPS study is the use of a mixed methods design in which a responsive and economic evaluation runs parallel to the trial. The results of this study will generate new evidence for the rehabilitation treatment of persons with PPS. Trial registration Dutch Trial Register NTR1371.
