Mult Scler Relat Disord 2024; 90:105773. [PMID: 39068819 DOI: 10.1016/j.msard.2024.105773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Revised: 06/29/2024] [Accepted: 07/14/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND People with multiple sclerosis (PwMS) exhibit reduced bone mineral density (BMD) across several anatomical regions. Studies have indicated that PwMS are at a heightened risk of fractures due to decreased BMD and increased prevalence of osteopenia and osteoporosis. This study aimed to investigate the prevalence and risk of osteopenia, osteoporosis, and fracture among PwMS. METHODS Relevant studies were identified through comprehensive searches of databases (PubMed/MEDLINE, Scopus, Embase, and Web of Science) from January 1, 2000, to January 21, 2024. R software version 4.4.0 and random-effects models were employed to estimate the pooled prevalence, odds ratio (OR), and risk ratio (RR) of osteopenia, osteoporosis, and fracture among PwMS, along with their respective 95 % confidence intervals (CIs). RESULTS From a total of 2039 articles, 51 studies with 1,503,785 PwMS met our inclusion criteria. The pooled prevalence of osteopenia, osteoporosis, and overall fracture among PwMS was 41.41 % (95 % CI: 36.14% to 46.69 %, I2=97 %), 14.21 % (95 % CI: 10.75 % to 17.68 %, I2=99 %), and 12.84 % (95 % CI: 8.49 % to 17.19 %, I2 = 100 %), respectively. The likelihood of osteopenia (OR=2.02, 95 % CI: 1.46 to 2.8, p-value<0.01, I2=17 %) and osteoporosis (OR=1.71, 95 % CI: 1.27 to 2.31, p-value<0.01, I2=74 %), as well as the probability of overall fracture (RR=1.86, 95 % CI: 1.61 to 2.14, p-value<0.01, I2=74 %) were significantly higher in PwMS than healthy controls (HCs). CONCLUSION PwMS were at a substantially increased risk of developing osteopenia (2-fold), osteoporosis (1.7-fold), and overall fractures (1.9-fold). Well-designed studies are needed to explore these associations further.

Abstract
INTRODUCTION Patients with multiple sclerosis (MS) commonly present musculoskeletal disorders characterized by lower bone mineral density (BMD) and muscle weakness. However, the underlying etiology remains unclear. Our objective is to identify shared pleiotropic genetic effects and estimate the causal relationship between MS and musculoskeletal disorders. MATERIALS AND METHODS We conducted linkage disequilibrium score regression (LDSR), colocalization, and Mendelian randomization (MR) analyses using summary statistics from recent large-scale genome-wide association studies (GWAS), encompassing MS, falls, fractures, and frailty. Additional MR analyses explored the causal relationship with musculoskeletal risk factors, such as BMD, lean mass, grip strength, and vitamin D. RESULTS We observed a moderate genetic correlation between MS and falls (RG = 0.10, P-value = 0.01) but not between MS with fracture or frailty in the LDSR analyses. MR revealed MS had no causal association with fracture and frailty but a moderate association with falls (OR: 1.004, FDR q-value = 0.018). We further performed colocalization analyses using nine SNPs that exhibited significant associations with both MS and falls in MR. Two SNPs (rs7731626 on ANKRD55 and rs701006 on OS9 gene) showed higher posterior probability of colocalization (PP.H4 = 0.927), suggesting potential pleiotropic effects between MS and falls. The nine genes are associated with central nervous system development and inflammation signaling pathways. CONCLUSION We found potential pleiotropic genetic effects between MS and falls. However, our analysis did not reveal a causal relationship between MS and increased risks of falls, fractures, or frailty. This suggests that the musculoskeletal disorders frequently reported in MS patients in clinical studies are more likely attributed to secondary factors associated with disease progression and treatment, rather than being directly caused by MS itself.

Abstract
PURPOSE Interest in fractures in patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) has considerably increased in the last decade. However, few studies have compared the incidence of fractures between patients with MS and NMOSD using a nationwide database. This study aimed to evaluate the differences in the risk of fracture between patients with NMOSD and MS compared to that in healthy controls using cohort data from a Korean nationwide database. METHODS In this retrospective cohort study, data from the National Health Insurance Service (NHIS) database from January 2010 to December 2017 were analyzed. A total of 1,217/1,329 patients with MS/NMOSD free of fractures at the index date were included. Matched controls were selected based on age, sex, and the presence of hypertension, diabetes mellitus, and dyslipidemia. The mean follow-up durations after the index date were 4.40/4.08 years for patients with MS/NMOSD and 4.73/4.28 for their matched controls. RESULTS The adjusted hazard ratios (aHRs) with 95% confidence intervals of any, hip, and vertebral fractures were 1.81 (1.43-2.28), 3.36 (1.81-6.24), and 2.01 (1.42-2.99) times higher for patients with MS than for controls, respectively, and they were 1.85 (1.47-2.34), 3.82 (2.05-7.11), and 2.84 (1.92-4.21) times higher for patients with NMOSD than for controls, respectively. No significant differences were observed in the incidence of fractures between the MS and NMOSD groups. Patients with MS/NMOSD had a 1.8-fold higher risk of fracture than matched controls, and the risk of hip fracture was especially high (3- to 4-fold higher). CONCLUSIONS Clinicians need to regularly assess patients with MS/NMOSD for the risk of fractures and take preventative measures to reduce it.

Abstract
AIM Sex hormones have been suggested to have neuroprotective effects in the natural history of multiple sclerosis (MS), particularly in animal studies. The aim of the present review was to retrieve and systematically synthesize the evidence on the effect of menopause and hormonal replacement treatment (HRT) on the course of MS. METHODS A systematic literature search was conducted in the databases MEDLINE (accessed through PubMed), Scopus, clinicaltrials.gov and Cochrane Controlled Register of Trials (CENTRAL). Eligible studies were all those that included women with MS and reported on at least one of the following: a) disability and MS relapse rate before and after menopause, b) serum sex hormone concentrations, c) sexual function, d) age at menopause onset. Effects of HRT on MS clinical outcomes were also assessed. RESULTS Of the 4,102 retrieved studies, 28 were included in the systematic review. Of these, one reported the age at menopause for both controls and women with MS and found no difference between the two groups. There was no difference in the rates of relapse before and after menopause (risk ratio 1.21, 95 % confidence interval 0.91-1.61, p = 0.218). Two intervention studies reported beneficial effects of estrogen therapy on women with MS; however, the majority of women were premenopausal. Three studies addressed the issue of sexual dysfunction in women with MS, but information on hormonal parameters was limited. CONCLUSIONS The age at menopause is not associated with the presence of MS. The evidence on a potential causal effect of estrogen depletion on disability is inconclusive; still, relapse rate seems not be associated with menopause. The effect of HRT on the natural course of the disease remains to be defined.

Determinants of low bone mineral density in people with multiple sclerosis: Role of physical activity. Mult Scler Relat Disord 2019; 38:101864. [PMID: 31801106 DOI: 10.1016/j.msard.2019.101864] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 11/20/2019] [Accepted: 11/22/2019] [Indexed: 11/23/2022]
Abstract
BACKGROUND People with multiple sclerosis (PwMS) have reduced bone mineral density (BMD), but the causes are unclear. Some factors that may cause reduced BMD in PwMS have been understudied, including physical activity, inflammation, cortisol, symptomatic fatigue, and depression. The aim of this study was to investigate factors that may uniquely contribute to reduced BMD in PwMS as compared to people without MS. We hypothesized that physical activity would be the primary determinant of low BMD in PwMS, with additional contributions from inflammation and sympathetic nervous system activation. METHODS We tested 23 PwMS (16 women; median EDSS: 2) and 22 control participants (16 women). BMD was measured from the femoral neck and lumbar spine with dual x-ray absorptiometry. Disability was measured with the Expanded Disability Status Scale, and functional capacity was measured with the Multiple Sclerosis Functional Composite. Questionnaires measured symptomatic fatigue and depression. A blood draw was used to measure calcium, phosphate, vitamin D, N-terminal telopeptide, osteopontin, and cytokine markers of inflammation. Physical activity was measured with accelerometry. Salivary cortisol and cardiac heart rate variability also were obtained. All outcome variables were compared between groups with independent samples t-tests. Variables that were different between groups and significantly correlated (Pearson product-moment) with femoral neck BMD, were included in a theoretical model to explain femoral neck BMD. The expected direction of relations in the theoretical model were developed based upon the results of previous research. A Bayesian path analysis was used to test the relations of predictive variables with femoral neck BMD and interrelations among predictive variables, as detailed in the theoretical model. RESULTS PwMS had lower BMD at the femoral neck than controls (p = =0.04; mean difference: -0.09; 95% CI: -0.2, -0.004; Cohen's d = =0.65), and there was a smaller, statistically non-significant difference in BMD at the lumbar spine (p = =0.07; mean difference: -0.08; 95% CI: -0.17, 0.007; Cohen's d = =0.59). PwMS also had lower functional capacity (p ≤ 0.001; Cohen's d = =1.50), greater fatigue (p<0.001; Cohen's d = =1.88), greater depression (p<0.001; d = =1.31), and decreased physical activity (p = =0.03; Cohen's d = =0.62). Using path analysis to test our theoretical model, we found that disability (standardized estimate= -0.17), physical activity (standardized estimate=0.39), symptomatic fatigue (standardized estimate= -0.36), depression (standardized estimate= -0.30), and inflammatory markers (standardized estimate=0.27) explained 51% of the variance in femoral neck BMD. Inflammatory markers were also predictive of disability (standardized estimate=0.44) and physical activity (standardized estimate= -0.40). Symptomatic fatigue and depression were correlated (r = =0.64). CONCLUSION Physical activity, symptomatic fatigue, depression, disability, and inflammation all contributed independently to decreased femoral neck BMD in PWMS. Bone metabolism in PwMS is complex. Efforts to increase physical activity and address symptomatic fatigue and depression may improve bone mineral density in PwMS. Future research should investigate the mechanisms through which symptomatic fatigue and depression contribute to reduced BMD in PwMS.

Abstract
Purpose The aim of this study is to compare the clinical and urodynamic characteristics of urinary disorders in multiple sclerosis (MS) patients in a geriatric population with a nongeriatric population. Methods This study was conducted retrospectively between 2010 and 2016. Each patient with MS aged 65 and older was matched with 2 patients with MS aged less than 65 in sex, form of MS, and Expended Disability Status Scale (EDSS). Demographic data, urinary symptoms, treatment, quality of life, repercussion of lower urinary tract symptoms on daily life activities and psychological state and urodynamic parameters were collected. Differences between the 2 populations were evaluated using Student test, chi-square, or Fischer tests. Results Twenty-four patients with MS aged 65 and older (mean age, 69.8 years) were matched with 48 patients aged less than 65 years (mean age, 49.4 years). Maximum urethral closure pressure was lower in the elderly population than in the nongeriatric population (mean±standard deviation [SD]: 35.6±18.5 cm H<sub>2</sub>O vs. 78.2±52.3 cm H<sub>2</sub>O, P<0.001). In the male population, there was no statistical difference in any other clinical or urodynamic endpoints. In the female population, voiding symptoms was more described in the nongeriatric population (Urinary Symptom Profile low stream: 3.4±3.5 vs. 1.7±2.4, P=0.04), geriatric population had less urinary treatment (P=0.05). LUTS had less impact on quality of life (Qualiveen: 1.4±1.0 vs. 2.1±0.9, P=0.02) on the geriatric population than in the nongeriatric of female MS patients. Conclusions Geriatric population of MS has few differences of urinary disorders compared to a nongeriatric population with EDSS, sex, and MS form equal. However, the psychological impact of these urinary disorders is less important in female geriatric population.

Abstract
BACKGROUND Patients with multiple sclerosis (MS) frequently require total joint arthroplasty (TJA). The outcomes of TJA in patients with MS, who are frequently on immunomodulatory medications and physically deconditioned, remain largely unknown. The aim of this study is to elucidate the survivorship and reasons for failure in this patient population. METHODS A single-institution retrospective review of 108 TJAs (46 knees and 62 hips) was performed from 2000 to 2016. An electronic chart query based on MS medications and International Classification of Diseases, Ninth Revision codes was used to identify this population followed by a manual review to confirm the diagnosis. Outcomes were then assessed using revision for any reason as the primary end point. Functional outcomes were assessed using Short Form 12 scores. Survivorship curves were generated using the Kaplan-Meier method. RESULTS At an average follow-up of 6.2 years, 19.4% (21/108) of patients required a revision surgery. Instability (5.6%, P = .0278) and periprosthetic joint infection (4.6%, P = .0757) were among the most common reasons for revision. The overall survivorship of TJA at years 2, 5, and 7, respectively, was 96.5% (95% confidence interval [CI], 92.6-100), 86.3% (95% CI, 77.7-94.5), and 75.3% (95% CI, 63.5-87.0). Functional score improvement was less in MS cohort than patients without MS. CONCLUSION Patients with MS are at increased risk of complications, particularly instability and periprosthetic joint infection. Despite this increased risk of complications, patients with MS can demonstrate improved functional outcomes, but not as much as patients without MS. Patients with MS should be counseled appropriately before undergoing TJA.

Abstract
BACKGROUND Hip fracture risk is high in young people with multiple sclerosis (MS), but has not been examined in an institutionalized aging population with MS. OBJECTIVE We aimed to compare the hip fracture risk in nursing home (NH) residents with and without MS; and (2) examine risk factors for hip fracture in those with MS. METHODS We conducted a retrospective cohort study using national NH clinical assessment and Medicare claims data. Participants included age-, sex- and race-matched NH residents with/without MS (2007-2008). Multivariable competing risk regression was used to compare 2-year hip fracture risk, and to examine risk factors. RESULTS A total of 5692 NH residents with MS were matched to 28,460 without MS. Approximately 80% of residents with MS vs. 50% of those without MS required extensive assistance in walking at NH admission. The adjusted incidence rate of hip fracture was 7.1 and 18.6 per 1000 person-years in those with or without MS, respectively. Wandering and anxiolytic exposure were the main hip fracture risk factors in transfer independent residents with MS; while pneumonia and antidepressant use were the main factors in dependent residents with MS. CONCLUSIONS In contrast to prior comparisons from non-NH populations, the incidence of hip fracture was lower in NH residents with MS as compared with matched controls. Residents with MS were much more functionally dependent, which likely explains these findings. Fracture prevention strategies should focus on fall prevention in independent residents; and possibly improvement of health status and facility quality of care in dependent residents.

Abstract
Multiple sclerosis (MS) is a chronic disease of the central nervous system (CNS) and the most widespread nontraumatic cause of disability in young adults around the world. MS occurs in people of all ages, races, and ethnicities. MS is characterized by clinical symptoms resulting from lesions in the brain, spinal cord, or optic nerves that can affect balance, gait, and fall risk. Lesions accumulate over time and occur in different areas of the CNS causing symptoms that include weakness, spasticity, and fatigue, as well as changes in sensation, coordination, vision, cognition, and bladder function. Thus, it is not surprising that imbalance, gait dysfunction, and falls are common in people with MS. The overwhelming majority have abnormalities of postural control and gait even early in the disease course. In all, 50-80% have balance and gait dysfunction and over 50% fall at least once each year. Balance dysfunction in MS is conceptualized as three interrelated problems: decreased ability to maintain position, limited and slowed movement towards limits of stability, and delayed responses to postural displacements and perturbations. In addition, functional balance performance may be affected by impaired dual-task integration. Walking changes in MS include reduced gait speed, impaired walking balance, and reduced walking-related physical activity. Falls in people with MS are associated with injuries, reduced participation, and increased fear of falling. A wide and growing range of rehabilitation and medical interventions are available to address the changes in balance, gait, and fall risk associated with MS.

Abstract
OBJECTIVES Increased risk of osteoporotic fractures in multiple sclerosis (MS) patients compared with general population has been reported. The purpose of this study was to assess the risk of osteoporotic and other low-energy fractures in an MS cohort from a large hospital district in southwest Finland. Age-adjusted total and gender-specific prevalence for definite MS per 100 000 in a population of 472 139 was calculated as a point prevalence in December 31, 2012. MATERIALS AND METHODS Patients with MS and comorbid fractures were identified by searching for ICD-9 and ICD-10 codes during a period from 2004 to 2012 from hospital administrative data in Turku University Hospital (TYKS) in southwest Finland Case ascertainment was performed by review of medical records. Osteoporotic fracture was defined as a low-energy fracture of the pelvis, hip, femur, tibia, humerus, collar bone, ulna/radius, vertebrae, or rib. The control population was a 10-fold age- and gender-matched population. RESULTS The point prevalence (N 1004) of MS was 212.6/105 (CI 199.5-225.8) in December 31, 2012. A total of 100 (9.9%) of 1004 confirmed MS cases experienced at least one fracture during the study period. Relative risks (RRs) for all fractures (1.33, 95% CI 1.10-1.60) and osteoporotic fractures (1.50, 95% CI 1.18-1.90) were significantly increased in patients with MS compared with controls. In particular, RRs for hip fractures (5.00, 95% CI 2.96-8.43) and fractures of humerus (2.36, 95% CI 1.32-4.42) were elevated in patients with MS vs controls. CONCLUSIONS We observed high prevalence of MS in southwest Finland and confirmed increased age-adjusted comorbid risk for osteoporotic fractures and other low-energy fractures compared with individually matched controls.

Abstract
Multiple sclerosis (MS) is a multifactorial, inflammatory, and neurodegenerative disease of the central nervous system, where environmental factors interact with genetic susceptibility. The role of diet on MS has not been comprehensively elucidated; therefore, through an extensive search of relevant literature, this review reports the most significant evidence regarding nutrition as a possible co-factor influencing the inflammatory cascade by acting on both its molecular pathways and gut microbiota. Since nutritional status and dietary habits in MS patients have not been extensively reported, the lack of a scientific-based consensus on dietary recommendation in MS could encourage many patients to experiment alternative dietetic regimens, increasing the risk of malnutrition. This work investigates the health implications of an unbalanced diet in MS, and collects recent findings on nutrients of great interest among MS patients and physicians. The aim of this review is to elucidate the role of an accurate nutritional counseling in MS to move toward a multidisciplinary management of the disease and to encourage future studies demonstrating the role of a healthy diet on the onset and course of MS.

Bone mineral density in patients with multiple sclerosis, hereditary ataxia or hereditary spastic paraplegia after at least 10 years of disease - a case control study. BMC Neurol 2016; 16:252. [PMID: 27919248 PMCID: PMC5139093 DOI: 10.1186/s12883-016-0771-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2016] [Accepted: 11/23/2016] [Indexed: 12/12/2022] Open
Abstract
Background Although disability is considered the main cause of low bone mineral density (BMD) in multiple sclerosis (MS), other factors related to the disease process or treatment could also be involved. The aim of this study was to assess whether patients with MS are more likely to develop low BMD (osteopenia or osteoporosis) than patients with the non-inflammatory neurological diseases Hereditary Spastic Paraplegia (HSP) and Hereditary Ataxia (HA). Methods We performed a case control study comparing BMD (spine, hip and total body) and biochemical measures of bone metabolism in 91 MS patients and 77 patients with HSP or HA, matched for age, gender and disability. Both patient groups had lived with the disease for at least 10 years. Results In total 74.7% of the patients with MS and 75.3% of the patients with HSP or HA had osteopenia (−2.5 < T- score < −1.0) or osteoporosis (T- score ≤ −2.5) in one or more sites. Osteoporosis was more common in patients with MS than with HSP/HA (44.0 vs 20.8%, p =0.001). This difference was not significant after correction for confounders (p = 0.07), nor were any of the biochemical markers. Conclusion Most patients with disabling neurological diseases like MS and HSP/HA develop osteopenia or osteoporosis. MS patients had osteoporosis more frequently than HA/HSP patients, though the difference was not significant after adjusting for confounders. Osteoporosis and bone health should be considered in all patients with both inflammatory and degenerative chronic neurological diseases.
