RESUMO
OBJECTIVE: The time to diagnosis of multiple sclerosis (MS) is of great importance for early treatment, thereby reducing the disability and burden of the disease. The purpose of this study was to determine the time from the onset of clinical symptoms to the diagnosis of MS and to evaluate the factors associated with a late diagnosis in Iranian MS patients. METHODS: The present cross-sectional study was conducted on patients with MS who were registered in the National MS Registry System of Iran (NMSRI). RESULTS: Overall, 23291 MS patients registered in 18 provinces of Iran were included in this study. The mean (standard deviation) interval between the onset of the disease and diagnosis of MS was 13.42 (32.40) months, and the median was one month. The diagnostic interval of 41.6% of patients was less than one month, and 14.8% of them had a one-month time to diagnosis. Patients with an age of onset below 18 years and those diagnosed after the age of 50 years had a longer time to diagnosis (P<0.001). Patients with primary progressive MS (PPMS) had the longest time to diagnose and those with relapsing-remitting MS (RRMS) had the shortest time (P<0.001). The results of negative binominal regression showed that the average rate of delay in diagnosis in women was 12% less than that in men. The average delay in diagnosis in patients with a positive family history of MS was 23% more than that in others. The rate of delay in the diagnosis of patients with PPMS and secondary progressive MS was 2.22 and 1.66 times higher, respectively, compared with RRMS. CONCLUSION: The findings of the present study revealed that more than half of the MS patients were diagnosed within a one-month interval from the symptom onset, which is an acceptable period. More attention should be paid to patients' access to medical facilities and MS specialists.

Background: It seems that patients with multiple sclerosis (MS) are at a higher risk for coronavirus disease 2019 (COVID-19) implications due to being subjected to immunomodulatory or immunosuppressive treatments. Besides, obesity as a risk factor may lead to more adverse consequences. The relationship between obesity and COVID-19 morbidity and outcomes in Iranian patients with MS still remains unclear. Methods: A cross-sectional study was conducted in Sina Hospital, Tehran, Iran. Patients with MS were asked to complete an online questionnaire in the Google Form format. Demographic information, clinical information including MS disease-related factors, COVID-19-related factors, and anthropometric information were recorded. Totally, 492 patients filled the questionnaire during two weeks in November 2021, by the response rate of 21.6%. Body mass index (BMI) was categorized based on the standard classification of the World Health Organization (WHO). The logistic regression was used to examine the risk of morbidity and chi-square test/one-way analysis of variance (ANOVA) was employed to determine the difference regarding severity and symptoms among groups. Results: In the fully adjusted model, the odds ratio (OR) of COVID-19 morbidity in class II obese participants was significantly 5.41 times higher than that in the normal BMI group [OR: 5.41, 95% confidence interval (CI): 1.00-29.09]. COVID-19 severity was significantly different among BMI groups (P = 0.024). Respiratory symptoms (P = 0.05) as well as gastrointestinal (GI) symptoms (P < 0.01) of COVID-19 were more prevalent among class I and class II obese patients compared with overweight, normal weight, and underweight groups. Moreover, no one in the class I and class II obesity groups reported COVID-19 morbidity without any symptoms (P = 0.04). Conclusion: The results of the current study support the view that obesity could play a key role in susceptibility to COVID-19 morbidity and severity of the symptoms in patients with MS. The findings recommended that neurologists pay more attention to patients' BMI during this pandemic.
RESUMO
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.
RESUMO
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.
RESUMO
Background: Due to the invariably progressive nature of multiple sclerosis (MS) and the high economic burden of chronic diseases, this study was performed to estimate the economic burden of MS medications in Iran. Methods: The present research is a descriptive study performed using comprehensive national data of Iran's Health Insurance Organization (IHIO). The timeframe for study was 2011-2019. In order to calculate the economic burden of MS medications, the cost of illness (COI) method based on the prevalence approach was used. In this study, economic burden estimation was performed according to available data on medication costs. Data mining was also used to perform different stages of study. Results: The number of patients receiving MS medications covered by IHIO has increased from 19,367 in 2011 to 50,642 in 2019. The economic burden of MS medications of patients covered by the IHIO increased from $81 million to $96 million between 2011 and 2019, respectively. Among the 9 medications studied, Interferon accounted for a very high share of costs in all years. The cost per patient receiving medication has also increased from $7,000 in 2011 to $18,000 in 2019. Conclusion: Calculations of the economic burden of MS medications in Iran showed an upward trend during the 9 years of the study, which due to the increasing number of patients in Iran, the arrival of new medications and also the increase in prices.
RESUMO
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.

Background: Multiple sclerosis (MS) is recognized as the most prevalent autoimmune abnormality of the CNS. T1WI, T2WI, and FLAIR are limited in the quantification of tissue damage and detection of tissue alterations in white and grey matter in MS. This study aimed to the evaluation of changes in DTI indices in these patients at the thalamus and basal ganglia. Methods: 30 relapsing-remitting MS (RRMS) cases and 30 normal individuals were included. Conventional MRI (T2, FLAIR) was acquired to confirm NAGM in MS patients. A T1 MPRAGE protocol was used to normalize DTI images. FSL, SPM, and Explore DTI software were employed to reach Mean Diffusivities (MD), Axial Diffusivities (AD), Fractional anisotropy (FA), and Radial Diffusivity (RD) at the thalamus and the basal ganglia. Results: The FA and RD of the thalamus were decreased in healthy controls compared to MS cases (0.319 vs. 0.296 and 0.0009 vs. 0.0006, respectively) (P < 0.05). The AD value in the thalamus and the FA value in the caudate nucleus were significantly lower in MS cases than in controls (0.0009 vs. 0.0011 and 0.16 vs. 0.18, respectively) (P < 0.05). MD values in the thalamus or basal ganglia were not significantly different between groups. Conclusions: DTI measures including FA, RD, and AD have a good diagnostic performance in detecting microstructural changes in the normal-appearing thalamus in cases with RRMS while they had no significant relationship with clinical signs in terms of EDSS. Availability of data and material: Not applicable.
RESUMO
BACKGROUND: Therapeutic plasma exchange (TPE) is a conventional second-line treatment for patients with multiple sclerosis (MS) or clinically isolated syndrome with steroid-refractory relapses. METHODS: MS and clinically isolated syndrome patients with a steroid-refractory relapse, who fulfilled the indications for TPE were enrolled in this study. An expert nurse recorded the data comprising age, sex, type of MS, disease modifying therapy, disease duration, relapse rate, vital signs at the beginning, during and at the end of each plasma exchange session, plasma exchange volume, normal saline volume, and TPE complications. Ultimately, the statistical association was estimated amongst the variables. RESULTS: A total of 122 cases were assessed. Twelve cases (9.8%) received plasmapheresis for the second time. The mean age was 32.2±8.7 years and 107 (87.7%) were female. In total, 609 plasma exchange sessions were completed. Hypotension and skin reaction were the most clinical complications. Hemoglobin loss and hypokalemia were the most laboratory complications. Fifty-four cases (44.3%) had no complications, 40 (32.8%) had 1 complication, 21 (17.2%) 2 complications, 6 (4.9%) had 3 complications, and 1 (0.8%) disclosed 4 complications. The relapse rate in the past 12 months and the mean plasma volume exchange were significantly different between the groups. CONCLUSIONS: We revealed that TPE could be considered as a safe second-line therapy in MS relapses. Hypotension, skin reaction, hemoglobin loss, and hypokalemia were the most complications of TPE in our patients.

Background: The present study examined the prevalence of obsessive-compulsive disorder (OCD) among Iranian patients with multiple sclerosis (MS) and the relationship between OCD and the patient's demographic characteristics. Methods: The present study used a cluster sampling method to randomly select 297 patients with MS from the patients referred to the MS Clinic and Research Center of Sina University Hospital, Tehran, Iran, during 2018-2019. To gather the required data, a questionnaire consisting of demographic characteristics and disease information sections was used. Moreover, Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Obsessive-Compulsive Inventory-Revised (OCI-R), and Hospital Anxiety and Depression Scale (HADS) were employed in the present study. The comparison of qualitative and quantitative values between OCD-positive and negative groups was examined with chi-square test and independent samples t-test, respectively. Binary logistic regression was used as multivariate modeling to adjust the effects of potential confounders that could distort the relation of OCD with intended variables. Data were analyzed using SPSS software. The significance level was considered lower than 0.05. Results: Of the total of 297 patients, 77.8% were women. Moreover, analysis of the data obtained from the HADS questionnaire revealed that 11.44% (n = 34) and 15.15% (n = 45) of patients had severe depression and severe anxiety, respectively. The results of Y-BOCS indicated that the prevalence of severe OCD among patients was 19.9%. The OCI-R questionnaire revealed that the prevalence of OCD was 47.8%, which was consistent with the total of moderate, severe, and extreme values of Y-BOCS (47.9%). Furthermore, the subscales of ordering-arranging with 69 patients (22.9%) and obsessing with 46 patients (15.5%) indicated the highest frequencies as compared to other subscales. Moreover, OCD had a significant relationship with depression, anxiety, and type of MS in this regard. Conclusion: In this study, the prevalence rate of OCD among patients with MS was higher than its rate among the general population.
RESUMO
Cognitive impairment (CI) occurs in about 40-65% of people with multiple sclerosis (MS) during the disease course. Cognitive rehabilitation has produced non-univocal results in MS patients. OBJECTIVE: The present study aimed to evaluate whether an Integrated Cognitive Rehabilitation Program (ICRP) in MS patients might significantly improve CI. METHODS: Forty patients with three phenotypes of MS were randomly assigned into two groups: the experimental group (EG, n = 20), which participated in the ICRP for 10 weeks of training; and the control group (CG, n = 20). All participants' cognitive functions were assessed at three timepoints (baseline, post-treatment, and 3-month follow-up) with the California Verbal Learning (CVLT), Brief Visuospatial Memory (BVMTR), Numerical Stroop, and Wisconsin tests. RESULTS: When compared to CG patients, EG patients showed significant improvements in several measures of cognitive performance after ICRP, including verbal learning, visuospatial memory, attention, and executive functions. CONCLUSIONS: Home-based ICRP can improve cognitive functions and prevent the deterioration of patients' cognitive deficits. As an integrated cognitive rehabilitation program aimed at potentiation of restorative and compensatory mechanisms, this approach might suggest an effective role in preserving neuronal flexibility as well as limiting the progression of cognitive dysfunction in MS.
RESUMO
BACKGROUND: Iran, as a middle income country, is one of the places with high and rising prevalence of multiple sclerosis (MS). Regarding the substantial economic burden, reviewing the trend in prescribed disease modifying treatments (DMTs) could be of help. Here we studied the DMT information of nearly 14000 MS cases and its trends change for 30 years to improve health services to patients. METHODS: The population base of this descriptive-analytical (cross-sectional) study consisted of all MS patients in the nationwide MS registry of Iran (NMSRI), up to August 1, 2021. Registrars from 15 provinces, 24 cities, 13 hospitals,8 MS associations, 16 private offices, and 7 clinics had entered the data. RESULTS: Overall, 14316 cases were enrolled. The majority (76.1%) were female. The youngest and eldest patients were 5 and 78 years old, respectively. Diagnosis delay was under one year in most cases (median: 0, IQR: 0 - 1). Most (61.4%) had RRMS. Generally, platform injectables (IFN beta, glatiramer acetate) were the most used DMTs until 2010. It seems that introduction of newer agents (antiCD20s and oral DMTs) resulted in a decrease in the use of former drugs since around 2015. Some unusual practices are prominent such as using not approved DMTs for PPMS over the years, or administering high efficacy drugs like natalizumab for CIS. The results indicate the remaining popularity of first line injectable DMTs in female and pediatric patients. DISCUSSION: Mean age (SD) at onset in our study (29 ± 8.8) is near the statistics in Asia and Oceania (28 ± 0.7). Concerns about COVID-19 had a noticeable impact on administering high efficacy drugs like rituximab and fingolimod. However, in male patients this approach has not been the case. It may be related to more aggressive disease course in this group. The other possible explanation could be planning for pregnancy in female cases. The popularity of platform injectable drugs in pediatric MS may be related to its favorable safety profile over the years. Another point in this group, is the superiority of rituximab over other highly efficient medications.

BACKGROUND: World Health Organization (WHO) mentioned COVID-19 vaccination as the safest way to eradicate this pandemic. In the meantime, vaccine hesitancy (a delay in accepting or rejecting the vaccine despite the availability of vaccination services) is a barrier. Hence, we studied this obstacle in the Iranian multiple sclerosis (MS) population. OBJECTIVE: MS patients eligible for vaccination were asked to complete a google form survey. Demographic information, MS disease-related factors, flu vaccination history, COVID-19 vaccination history, cause of vaccination refusal, past history of COVID-19 infection, and their compliance with public health guidelines after vaccination were recorded. RESULTS: 1479 patients participated in this study. 6.9% of participants have not received the vaccination. Sinopharm was the most commonly used vaccine (92.9%). Vaccine hesitancy was associated with young age, lower education, unemployment, negative flu vaccination history, no previous episode of COVID-19 infection, less concern about COVID-19, and the expectation of not getting infected with the virus after vaccination. Participants mentioned concerns about the side effects of the vaccines as the most prevalent cause of avoiding vaccination (58.0%). Patients' concern of SARS-CoV-2 significantly decreased after vaccination (p-value < 0.001). CONCLUSION: Our findings in this study elucidate that a minor group of patients with MS has vaccine hesitancy, which may expose them to more severe COVID 19. The treating physicians should ask the history of vaccination and try to persuade such patients with scientific knowledge transformation. The long-term consequences of not being vaccinated should be clarified to such patients especially those who are receiving immunosuppressive agents.

BACKGROUND: At this time vaccination against SARS-CoV2 is a global priority. Cases with multiple sclerosis (MS) were among the first vaccinated populations in Iran. We evaluated the change in the frequency of COVID-19 after vaccination and the associated factors with severe COVID-19 infection before and after full vaccination. METHODS: A questionnaire was validated to investigate the basic characteristics (age, gender, education, body mass index, smoking status, and comorbidities), MS disease and treatment status (MS type, MS duration, The Expanded Disability Status Scale (EDSS), disease modifying treatments) and the information about COVID-19 infection and severity. RESULTS: 692 (91.9%) of participants have received both doses of vaccines, of which Sinopharm appeared to be the most common type. Significant difference of COVID-19 infection prevalence was seen before vaccination and after full vaccination (difference: 0.16, 95% CI: 0.12-0.20) (p value < 0.001). The difference was not significant for severe cases (those who were admitted in the ward or ICU) relative to the COVID-19 cases or the whole participants. Of all the basic and disease factors, only EDSS showed a significant association with severe COVID-19 before vaccination. Severe COVID-19 in fully vaccinated cases did not show any significant relation to any of basic or disease characteristics except with prior history of severe allergic reactions (OR: 17.1, p value: 0.001). DISCUSSION: The decreased frequency of infection with SARS-CoV2 was predictable but the insignificant difference in cases with the severe forms of the disease raise concern. The only significant predictor was found to be severe allergic reactions. As there are debates on antiCD20 s association with severe COVID-19 and vaccine efficacy, we could not find such significant relation. The other noticeable point about the found relation of EDSS and critical COVID-19 before vaccination is the absence of such relation after full vaccination.

BACKGROUND: Due to the high and increasing economic burden of chronic diseases, including Multiple sclerosis (MS), we aimed to investigate the medical cost of MS in Iran. METHODS: This is a descriptive cross-sectional study which conducted using comprehensive national prescription data from Iran's Health Insurance Organization (IHIO) and rehabilitation data from Ministry of Health and Iran Welfare Organization. The time period considered for this study was 2019-2020. In order to calculate the medical cost of MS, the cost-of-illness (COI) method was used based on the prevalence-based approach and the cost of medications, determining and diagnosing the MS risk, follow-up and rehabilitation was estimated. RESULTS: The total medical cost of MS in Iran in 2019-2020 was estimated at $238,124,160, which medications and rehabilitation services had the largest share in the medical cost of MS in Iran with 80 and 19%, respectively, and the cost share of determining and diagnosing of the disease risk accounted for about less than 1%. The total medication cost was estimated to be equal to $192,298 thousand. The total cost of determining and diagnosing of the MS risk was estimated at $348,574 and the total cost of rehabilitation services for all MS subgroups in 2019-2020 was estimated at $45,477,205. CONCLUSIONS: Results of calculating the medical cost of MS in Iran in 2019-2020 showed a significant burden on the Iranian health care system and society, among which the medication cost had the largest share, which requires serious attention of health system policymakers.

Background: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease of the central nervous system (CNS) that prompts immediate potent treatment. Delaying treatment could leave debilitating sequelae. As erythropoietin (EPO) has shown neuroprotective effects, we studied the effects of adding EPO to intravenous methylprednisolone (IVMP) in patients with acute attacks of NMOSD. Methods: NMOSD cases with acute attacks were included. Cases of optic neuritis (ON) and those with myelitis were separated. After randomization [with block sizes of 2 (1:1 ratio)], the patients in the intervention group received IVMP 1000 mg/day and intravenous (IV) EPO 20000 U/day for five days. IVMP 1000 mg/day and normal saline (NS) were administered in the control group. Staged eye score and motor forces were evaluated in the patients with ON and myelitis, respectively, at the time of the attack and three months later. Primary patient allocation and clinical assessments were blinded to the physicians. Results: Mean age of participants was 53.87 ± 11.53 years. At follow-up, in the ON arm, the median improvement in staged eye score was 2 in the control and 5 in the intervention group. The difference was significant (P < 0.001). In the myelitis group, none of the patients in the control group had improvement in motor forces. All the patients in the intervention group showed substantial improvement with minimal or no remaining weakness. The difference was statistically significant (P = 0.029). Conclusion: The results show the possible benefit of adding EPO to the classic IVMP in attacks of NMOSD in both visual and motor aspects.
RESUMO
Background: Now that the majority of the population has been immunized with two-dose vaccines, debates over the third booster dose have been raised. We studied the viewpoint of cases with multiple sclerosis (MS) on this matter. Methods: In a cross-sectional study, a google form containing questions about participants' characteristics, the history of coronavirus disease 2019 (COVID-19) infection and vaccination, and opinions on the third dose was designed. Results: Of 1067 responders, only 16 (1.5%) were not vaccinated at all. The most used vaccine type was Sinopharm BBIBP COVID-19 vaccine (BBIBP-CorV) (n = 1002, 93.9%). Generally, 58 (5.4%) cases were hospitalized due to COVID-19. Of those with full vaccination, 134 (13.3%) got COVID-19 infection after the second dose. Only 13 participants (1%) did not agree with the third dose, while 564 (53.0%) believed that a booster dose was needed. Of all, 488 (45.7%) declared that they did not have a final idea and would follow the instructions by the experts. A significant association was found between not receiving the first two doses and not believing in the third dose (P = 0.001). 692 patients declared their reasoning for the importance of the third dose. All the cases who thought the administered vaccine was not efficient enough had received Sinopharm BBIBP-CorV. Those who got infected after full vaccination were more uncertain about the efficacy of the vaccine [odds ratio (OR): 2.6, 95% confidence interval (CI): 1.6-4.2]. Conclusion: It seems that the majority of the Iranian patients with MS expect the authorities to administer a third booster dose, especially if scientifically validated.
RESUMO
NMOSD: is a disease shown to be highly associated with other diseases such as autoimmune diseases. There are a few reports of this association with cancer. So, this systematic review aimed to obtain a broad understanding on the cancers associated in NMOSD, including the source of common perceptions and assumptions in this regard. METHODS: in this study, we systematically searched the PubMed, EMBASE, SCOPUS, Web of Sciences, Proquest, Ovid, conference proceedings, and reference lists of the retrieved articles. All NMOSD cases who met the last version of criteria for its diagnosis, which reported the patients with a history of cancer before or after the onset of neurological symptoms without time limitations, and those who were referred as paraneoplastic neuromyelitis optica in articles published in English language (both the abstract & full text), were assessed. Finally, each study was critically appraised. RESULTS: Only 47 studies met the inclusion criteria, so they were assessed for qualitative synthesis. Considering the Euro network criteria, only 62 cases met this issue. The mean age of 52.21 ± 17.14 and 52.16 ± 17.21 was reported for cancer and NMOSD cases with female predominance (79%), respectively. The most reported organ in the cancer population were genitourinary (n = 14, 22.3%), breast (n = 12, 19.4%), lung (n = 12, 19.3%), gastrointestinal (n = 7, 11.3%), and hematology (n = 6, 9.7%), respectively. CONCLUSION: In older NMOSD patients without suspicious symptoms, we recommend paying more attention to lung, breast and genitourinary (especially ovary) cancer screening. Also, cancer resection had positive effect on the attack numbers after receiving treatment and NMOSD recovery.

MS patients were one of the first populations vaccinated in Iran. To date, the most used vaccine brand on Iranian MS patients is Sinopharm COVID-19 vaccine. Here is the first study on the adverse events after the first dose of Sinopharm vaccine on 583 Iranian MS patients. A Google form link was sent to MS patients through social networks, between May 1, 2021 and May 22, 2021. No serious adverse event was reported. At least one complaint (mostly transient) was reported by 350 (60%) of vaccine recipients. Constitutional symptoms (malaise, fatigue, fever, shivering, & generalized body pain) (51%) and headache (9%) were the most reported complaints. We found a relation between gender and prior infection with COVID-19 and reported symptoms (p value less than 0.05). Only five recipients (0.9%) reported MS relapse after vaccination. MS worsening was a minor incident related to fever.

BACKGROUND: Patients with multiple sclerosis (MS) suffer from a wide range of psychological problems. Application of a valid and reliable tool for psychosocial assessment is required for Iranian patients. The aim of this study is to determine the psychometric properties of the Persian version of the PARADISE-24 questionnaire in Iranian patients with multiple sclerosis. METHODS: One hundred and thirteen multiple sclerosis cases were enrolled in this study. Participants were asked to answer the valid and reliable Persian version of the fatigue severity scale, social support scale, Pittsburg sleep quality index, and hospital anxiety and depression scale and translated version of the PARADISE-24 questionnaire. Twenty cases filed the questionnaire 2 weeks later to assess reliability. The intraclass correlation coefficient, Cronbach's alpha, correlation coefficients, and multiple regression analysis were used. RESULTS: Mean age and mean duration of the disease were 35.8 ± 9.9 and 8.7 ± 5.6 years, respectively. The intraclass correlation coefficients ranged from 0.8 to 0.94 and Cronbach's alpha values (Cronbach's alpha was calculated as 0.91 for the whole questionnaire) were also significant. There were significant correlations between PARADISE-24 score and expanded disability status scale (r = 0.42, P < 0.001), fatigue severity scale (r = 0.62, P < 0.001), anxiety (r = 0.43, P < 0.001) and Pittsburg sleep quality index scores (r = 0.46, P < 0.001). Regression analysis by considering PARADISE-24 as dependent and other variables as independent showed that expanded disability status scale, fatigue severity scale, anxiety score, and Pittsburg sleep quality index were positive predictors of PARADISE-24 score. CONCLUSIONS: Persian version of PARADISE-24 questionnaire is a valid and reliable instrument for evaluating psychosocial aspects in patients with multiple sclerosis.
