Exploring the relationship between disability status, depression, and quality of life in individuals with multiple sclerosis.

INTRODUCTION: Depression and the presence of a disability emerge as noteworthy predictors of the quality of life (QoL) in patients with multiple sclerosis (MS). In this article, we explore the relationship between disability status, depression, and quality of life in individuals with multiple sclerosis. METHODS: A total of 150 patients participated in this cross-sectional study. A Persian translation of the Multiple Sclerosis Quality of Life-54 questionnaire was utilized to assess their health-related quality of life (QoL), while the patients' disability levels were measured using the Expanded Disability Status Scale. Additionally, we assessed patients' depression levels using the 21-item BDI-II scale. The questionnaire data were analyzed using SPSS version 25. RESULTS: A total of 150 MS patients participated in the study, with a mean age of 33.4 years (SD = 3.1). The majority were female (n = 71.2 %). The mean EDSS score was 3.7 (SD = 1.8). In the correlation analysis, we found that EDSS scores were not significantly correlated with mental QoL (r = -0.180, p = 0.109), but were significantly correlated with lower physical QoL (r = -0.393, p 0.001). Depression scores were significantly correlated with mental QoL (r = -0.776, P 0.001) and physical QoL (r = -0. 726, P 0.001). The results reveal that both EDSS and Beck scores significantly affect mental and physical health, explaining 62 % and 60 % of their variances, respectively. CONCLUSION: Our findings indicate a significant relationship between physical quality of life and EDSS scores in MS patients. Higher EDSS scores consistently corresponded to more significant physical impact, as evidenced by higher impact ratings. Conversely, there was no clear association between EDSS scores and mental quality of life. Furthermore, increased depression levels were linked to reduced levels of both mental and physical well-being. These results emphasize the intricate interplay between the physical aspects of quality of life and their implications for the progression and severity of MS in patients.

Iranian specialists' approach to treatment escalation in multiple sclerosis patients with cognitive impairment.

Background: People with multiple sclerosis (MS) and their physicians recognize cognitive retention as an important desired outcome of disease-modifying therapies (DMTs). In this study, we attempted to gather the opinions of Iranian MS experts regarding the treatment approach toward clinical cases with different physical and cognitive conditions. Methods: Opinions of 20 MS specialists regarding the best approach to 6 case scenarios (with different clinical, cognitive, and imaging characteristics) were gathered via a form. Results: The estimated kappa of 0.16 [95% confidence interval (CI): 0.159-0.163; P < 0.001] suggested a poor degree of agreement on the treatment choice among the professionals. Conclusion: Although most specialists agreed with treatment escalation in cases with cognitive impairment, there was no general agreement. Furthermore, there was not enough clinical evidence in the literature to develop consensus guidelines on the matter.

Iranian specialists' approach to surgery in patients with multiple sclerosis.

Background: Data on perioperative risk stratification in patients with multiple sclerosis (MS) are limited. In this regard, the present study was conducted to investigate Iranian specialists' approach to surgical counseling for patients with MS (PwMS). Methods: 21 MS specialists were asked about 11 case scenarios with different MS disease statuses, disease-modifying therapies (DMTs), and urgency of the operation. The reasons for refusing surgery or factors that have to be considered before surgery were studied. Results: Overall, Fleiss Kappa was estimated to be 0.091 [95% confidence interval (CI): 0.090-0.093, P < 0.001] indicating a very poor level of agreement among responders. Conclusion: PwMS face surgery for various reasons. Risk assessment of surgery, the effect of various drugs such as anesthetics and DMT on patients, as well as many other aspects of MS are issues challenging the practitioners. Clarifying the various dimensions of these issues requires further research.

The effects of different types of smoking on recovery from attack in hospitalized multiple sclerosis patients.

BACKGROUND: Several studies demonstrated the association between tobacco smoking and higher risk and increased progression of multiple sclerosis (MS). Data about the effect of smoking during the recovery from MS attacks is limited. Furthermore, different types of tobacco exposures such as water pipe and passive smoking are not well assessed separately. So this study evaluated the effect of different types of smokes, cigarette and water pipe as well as passive smoking on the function recovery of relapsing-remitting MS (RRMS) attacks METHODS: This cohort study evaluated the adult patients with RRMS and Expanded Disability Status Scale (EDSS) < 5 in the attack phase. Patients were divided into two groups: smokers and non-smokers. The smokers included those who use cigarette, water pipe as well as passive smokers as subgroups for more analyses later. EDSS was monitored after relapse and two months after relapse. Change of EDSS considered as the criteria for functional recovery. The correlation between the amount of consumption and disability level was assessed among smokers by Pearson's correlation test. While, the difference of EDSS between smoker and non-smoker were assessed by Independent samples T-test. RESULTS: 142 patients were evaluated. 79 (55.6%) were smokers (43% male) while 63 (44.4%) were non-smokers (36.5% male). There was a statistically significant difference in change of EDSS between smoker and non-smoker groups, which change of EDSS was higher in non-smoker (-2.62 ± 0.90 non-smoker vs. -1.75 ± 0.76 smoker, P < 0.001). Also, only there was a significantly lesser decline in EDSS after two months in the cigarette smokers in subgroups analyses (P < 0.001). A correlation analysis revealed a significant positive correlation between the number per day of cigarette smoking and EDSS after relapse (r = 0.3, P = 0.03) and a significant positive correlation between minutes per month of smoking of water pipe and EDSS two months after relapse (r =  0.6 , P > 0.001). CONCLUSION: Tobacco smoking especially cigarette smoking is associated with a negative effect on recovery from the attack in patients with RRMS.

Late-onset multiple sclerosis in Iran: A report on demographic and disease characteristics.

BACKGROUND: Today, it is estimated that around 5% of multiple sclerosis (MS) patients are in the late-onset category (age at disease onset ≥ 50). Diagnosis and treatment in this group could be challenging. Here, we report the latest update on the characteristics of Iranian patients with late-onset MS (LOMS). METHODS: This cross-sectional study used the information provided by the nationwide MS registry of Iran (NMSRI). The registrars from 14 provinces entered data of patients with a confirmed diagnosis of MS by neurologists. Patients with disease onset at or later than 50 years of age were considered LOMS. RESULTS: Of 20,036 records, the late-onset category included 321 patients (1.6%). The age-standardized LOMS prevalence was around 75 per 100,000 people. 215 patients (67%) were female. Median Expanded Disability Status Scale (EDSS) was 3 (interquartile range: 1.5-5). The majority of the cases (56%) suffered from relapsing-remitting (RR) course while 20% were diagnosed with primary progressive (PP) MS. Significantly higher proportion of male sex, PPMS, and higher EDSS were seen in the late-onset group compared with early-onset and adult-onset cases (p-value < 0.05). Seventy-five (23%) patients did not receive any disease-modifying treatment. DISCUSSION: The more prominent degenerative pathology of LOMS may be the underlying mechanism of the observed differences in comparison to non-LOMS. CONCLUSION: There are substantial differences and knowledge gaps regarding LOMS which could be the subject of further research.

Gut microbiome in multiple sclerosis-related cognitive impairment.

Cognition is one of the most evaluated neurologic subjects with which the gut microbiome is supposed to be associated. Cognitive impairment is a prevalent finding in patients with multiple sclerosis (MS). Here, we are about to study the current evidence on the effect of gut microbiota on cognition and MS. Although no direct evidence is in hand, putting all indirect research together, one could think of the hypothetical benefit of brain-gut axis interventions (possibly diet changes, probiotic administration, microbiota transplant) to solve the drastic problem of cognitive impairment in MS. Hence, researchers are encouraged to scan this horizon in order to fill the knowledge gaps in the field.
