Time interval between the onset of symptoms and diagnosis of multiple sclerosis and the influential factors: A national registry-based study. Clin Neurol Neurosurg 2024; 239:108221. [PMID: 38447483 DOI: 10.1016/j.clineuro.2024.108221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 02/25/2024] [Accepted: 02/29/2024] [Indexed: 03/08/2024]
Abstract
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.

Comparing infusion-related reactions of the first full dose (600 mg) biosimilar ocrelizumab administration with the standard divided protocol in multiple sclerosis patients: a randomized controlled trial study. Acta Neurol Belg 2024; 124:205-212. [PMID: 37715074 DOI: 10.1007/s13760-023-02366-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 08/16/2023] [Indexed: 09/17/2023]
Abstract
BACKGROUND Ocrelizumab is a humanized antiCD20, thought to be a highly effective disease-modifying therapy (DMT). Its most frequent adverse effects are infusion-related reactions (IRRs). To reduce these reactions, the first dose of ocrelizumab is administered as two 300 mg infusions separated by two weeks. However, in the phase II trial of ocrelizumab, severe IRRs were not significantly different between two doses of 600 mg dose (two separate 300 mg doses) and 2000 mg dose (two separate 1000 mg doses). We compared the IRRs in undivided full (one 600 mg) and divided (two 300 mg) doses of ocrelizumab which is the standard protocol. METHODS MS patients (relapsing or primary progressive MS) who are selected to receive ocrelizumab by neurologist or MS fellowship were enrolled in an open-label randomized controlled trial. Iranian biosimilar of the drug (Xacrel® by Cinnagen, approved by the Iranian Food and Drug Administration in 2021) was used. The participants received the first dose of ocrelizumab as either one 600 mg dose in one session or two 300 mg doses in two weeks apart. IRRs during or in the first 24 h after infusion were recorded. RESULTS Of 332 participants, 150 received two 300 mg doses, and 182 received one 600 mg dose (by random selection). Life-threatening adverse effects were not observed in both groups. Overnight admission or permanent drug discontinuation was not needed. Temporary drug discontinuation was significantly higher in the one 600 mg dose group (p-value < 0.001). During the infusions, malaise (p-value: 0.003), skin reactions (p-value: 0.04), throat swelling (p-value: 0.03), and dyspnea (p-value: 0.01) were significantly increased in the intervention group. However, in the first 24 h, there was no significant difference between two different treatment protocols (one 600 mg dose or two 300 mg doses) in the onset of IRRS (p-value: 0.12). CONCLUSION These findings suggest one 600 mg dose of ocrelizumab administration for the first dose is relatively safe. With some protocol modifications, it could lead to fewer patient referrals, saving time and cost and improvement the access for patients.

Abstract
BACKGROUND Multiple sclerosis (MS) may be affected by socioeconomic status (SES). This study aims to explore the determinants of SES among Iranian patients with MS and examine how these factors relate to disability and disease progression. METHODS All patients with MS listed in the nationwide MS registry of Iran (NMSRI) until January 8, 2022, were included in this population-based study. RESULTS Among the 5153 patients, most were female (74.5%), married (70.8%), and did not hold an academic degree (53.8%). Unemployment (OR: 3.75) and being unmarried (OR: 2.60) were significantly associated with Expanded Disability Status Scale (EDSS)≥6, and the time to progression was shorter in the unemployed group (P value: 0.03). There was also a significant negative correlation between the time to progression and the age at disease onset. CONCLUSION The study suggests that providing financial and social support to MS patients and their families through investment could reduce both individual and societal burdens.

Iranian specialists' approach to surgery in patients with multiple sclerosis. CURRENT JOURNAL OF NEUROLOGY 2023; 22:96-102. [PMID: 38011379 PMCID: PMC10460921 DOI: 10.18502/cjn.v22i2.13336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Accepted: 02/03/2023] [Indexed: 11/29/2023]
Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND One of the important challenges in the treatment of patients with multiple sclerosis (MS) is determining the effective factors in the treatment of MS, including dietary adherence. The aim of this study was to investigate the relationship between adherence to the Mediterranean diet with anthropometric indices and the expanded disability status scale (EDSS) scores in patients with MS. MATERIAL AND METHODS The present multicenter and cross-sectional study was conducted on patients with clinically definite MS (according to the 2017 revised McDonald criteria) who were referred to the MS clinics at medical centers affiliated to Shiraz and Tehran Universities of Medical Sciences during 2019. Disease phenotype, EDSS, waist circumference (WC), body mass index (BMI), and comorbidities were assessed. Adherence to the Mediterranean diet was measured with a 14-item modified Mediterranean Diet Adherence Questionnaire. In this questionnaire, a score of 0-5 indicates low adherence, a score of 6-9 shows moderate adherence, and a score of 10 and above demonstrates high adherence (healthy eating pattern). RESULTS This study was performed on 478 patients with a mean age of 37.99 ± 9.60 years, out of which 352 patients (73.6%) were female. The percentage of low, medium, and high adherence to the Mediterranean diet in patients with MS was 26.4%, 64%, and 9.6%, respectively. The difference in the level of education between the groups based on adherence to the Mediterranean diet was statistically significant. Low adherence to the Mediterranean diet in underweight, normal, and overweight patients was, respectively, 1.31, 1.32, and 2.29 times higher than in obese patients. This increased risk was only significant in overweight patients (P = 0.019). The results revealed that the score of adherence to the Mediterranean diet had no significant relationship with mild (2.86 ± 2.18), moderate (2.76 ± 2.16), and severe (2.70 ± 2.02) levels of disability. CONCLUSION The level of adherence to the Mediterranean diet in Iranian patients with MS was moderate. This level was associated with BMI, such that low adherence to the Mediterranean diet was higher in overweight patients than obese patients.

Prescription trends of disease-modifying treatments for multiple sclerosis in Iran over the past 30 years. Mult Scler Relat Disord 2022; 61:103777.

Abstract
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.

Abstract
PURPOSE To evaluate the effects of arch size and implant angulation on the accuracy of implant impressions. MATERIALS AND METHODS Four different resin models (small and large) of edentulous maxilla were fabricated and four implants were inserted (Blossom®, ø 4.75 × 10 mm) in each model. Implants were either parallel or angled 25° buccally. Forty working casts (small parallel, small angled, large parallel, and large angled) were fabricated in dental stone (n=10). For each implant, linear and angular displacements were measured using a coordinate-measuring machine (CMM) and mean values were analyzed by univariate analysis (α = 0.05). RESULTS Arch size did not affect the linear or angular displacement (P ⟩ .05). However, the implant angulation had a marked influence on the linear displacement (P ⟨ .05). The largest linear displacement occurred in implant no. 4 of angled small groups. CONCLUSION Regardless of arch size, linear and angular accuracy of implant impression varied with the implant angulation.

Abstract
Drug abuse is one of the most important threats to human beings today, leading to disability and even early death. In the past, opium had only therapeutic uses, but now, drug addiction is one of the major public health problems in Iran. Opium and its derivatives are the most commonly used illicit drugs in this country. Therefore, this study was conducted to evaluate the treatment strategies of opium addiction from the perspective of Persian medicine. In this narrative review, the search was conducted using appropriate keywords in the authoritative books of Persian medicine documentations of databases of PubMed, Google Scholar, PsycINFO, American Academy of Medical Sciences, United Nations Office on Drugs and Crimes with keywords of opioid and opium since 2000 AD. In Persian medicine books, "Afioon" means poppy plant (Papaver somniferum), which is called opium in English and "Theriac" in Persian. To quit, they should be gradually reduced and replaced with appropriate spices such as henbane (Hyoscyamus niger) seeds or mandrake (Mandragora officinarum) fruit or root or poppy (P. somniferum) seeds or poppy shell or Lettuce (Lactuca sativa) seeds, or castor testis or nutmeg (Myristans fragrans) fruit or ajwain (Trachyspermum copticum) seeds or baked bread. Opioid quit should be gradual and delayed in time of consumption and gradual reduction of opium levels, and bodies that have become lean for a long time will gradually recover with adequate nutrition over time.

Abstract
Fingolimod has been the first approved oral medication in MS for its relapsing remitting type. It is a non-selective sphingosine1-phosphate (S1P) receptor modulator on lymphocytes. Engagement of this receptor blocks the T cells and B cells migration from the lymph nodes into the inflamed central nervous system (CNS) via bloodstream. In spite of this known immunomodulatory mechanism, there are some reports about serious infection following the initiation of fingolimod therapy like herpes types or infections associated to the immunosuppressed situation (cryptococcal meningitis, primary cutaneous cryptococcosis and visceral leishmaniasis). To the best of our knowledge, in contrary to many reports about opportunistic or serious infections with fingolimod, there has been no report on fungal osteomyelitis associated to fingolimod until now. Here, we aimed to describe a woman who developed necrotizing fungal osteomyelitis four years after starting fingolimod, as a disease modifying drug for MS.

Abstract
Background Migraine is the second most common type of headache after tension headaches. In Iranian traditional medicine several herbal drugs are used for the treatment of headache. Including, a product of Iranian traditional medicine, a combination of Viola odorata L. flowers, Rosa damascena L. flowers and Coriandrum sativum L. fruits. Objective To determine the effectiveness of a combination of Viola odorata flowers, Rosa damascene flowers and Coriandrum sativum fruits on severity, duration and frequency of migraine headaches. Methods This randomized, double blind, placebo-controlled clinical trial was performed on 88 patients who had migraine and visited Besat Neurology Clinic No. 4 at Kerman University of Medical Sciences, Kerman, Iran, from September 2016 to march 2017. Patients were randomly divided into the intervention (n=44) or placebo group (n=44). The intervention group received a product of Iranian traditional medicine, a combination of Viola odorata L. flowers, Rosa damascena L. flowers and Coriandrum sativum L. fruits in 500 mg capsules three times a day and propranolol 20mg tablet twice a day, and the control group received placebo capsules (500mg) three times a day and propranolol 20mg tablet twice a day for four weeks. Patients were asked to report the frequency, duration and severity of their headaches in designed forms at home. Then at the end of the 2nd and 4th weeks of treatment, patients were followed for clinical efficacy. Results In terms of duration, frequency and severity of headaches between the two groups of herbal medicine and placebo, the behavior of the two protocols was changed over time (p<0.001). During the 4 weeks, the time and drug interactions, were significant (p <0.001). In other words, the pattern of changes to the two protocols over time, was different. Also, at the end of the 4th week, there was a significant difference between the two groups (p<0.001). Conclusion The study findings suggest that the Iranian traditional product combination of Viola odorata flowers, Rosa damascena flowers and Coriandrum sativum fruits may be effective in improving headaches in patients with migraine. Clinical trial registration The trial was registered at the Iranian registry of clinical trials (IRCT: www.irct.ir) with registered NO. IRCT 2016110830776N1.

Abstract
BACKGROUND The races show different cerebrovascular involvements, for example, the involvement of intracranial arteries are higher among Asians than Caucasians. The aim of this study was to investigate the cerebrovascular stenosis pattern by computed tomography angiography (CTA), which is unprecedented in Iran. METHODS In this study, patients with brain stroke (thrombosis), confirmed by CT scanning and cardiac assessments, who referred to Shafa Hospital in Kerman, Iran, underwent brain and cervical arteries CT angiography to assess involved cerebrovascular territories and also its risk factors from June 2012 to June 2013. RESULTS We did CTA for 100 patients. Eighty-four cases had cerebral artery stenosis. Intracranial vessel involvement alone was observed in 47.6% of patients, simultaneous intracranial and extracranial artery stenosis in 26.2%, and extracranial artery stenosis in 26.2%. Posterior cerebral artery territory showed the highest degree of vascular stenosis. Posterior cerebral artery stenosis alone was observed in 51.3% of the cases; 27.4% of the cases suffered from anterior artery stenosis, and 21.6% had simultaneous anterior and posterior cerebral artery stenosis. Smokers showed higher extracranial artery involvement compared to non-smokers; 44% of smokers and 14% of non-smokers had extracranial vertebral involvement. CONCLUSION Our findings showed that intracranial artery involvement was the most prevalent finding in patients with thrombotic stroke in Kerman. Also posterior cerebral artery stenosis was more prevalent than anterior artery stenosis. Hypertension was the most common risk factor. Furthermore, smoking was considered as an important risk factor for extracranial artery stenosis, especially in the posterior cerebral artery.

Abstract
BACKGROUND The genus Artemisia belonging to the Compositae (Asteraceae) family and many traditional uses from the Artemisia species were reported. Artemisia absinthium is one of the species in this genus and commonly used in the food industry in the preparation of aperitifs, bitters, and spirits. OBJECTIVE Evaluation of the effect of different harvesting stages on the composition of essential oil and antioxidant capacity of A. absinthium. MATERIALS AND METHODS Essential oils from the aerial parts of A. absinthium, collected in three stages (preflowering, flowering, and after-flowering) from plants grown in the North Khorasan province of Iran were obtained by steam distillation and the chemical composition of the oils was analyzed by gas chromatography-mass spectrometry and antioxidant activity and total phenolic content were determined by 2-diphenyl-1-picrylhydrazyl assay and Folin-Ciocalteu method. RESULTS Analysis of the isolated oils revealed the presence of 44 compounds, mainly alpha-pinene, sabinene, beta-pinene, alpha-phellandrene, p-cymene and chamazulene. Alpha-phellandrene, and chamazulene were major compounds in preflowering stage, but beta-pinene and alpha-phellandrene were major in flowering and past-flowering stages. Flowering stage had highest yield and after flowering stage had lowest yield. The essential oil of preflowering stage had the highest amount of antioxidant compound (chamazulene). Preflowering stage with highest amount of phenolic compounds had the strongest antioxidant activity with the lowest amount of EC50. CONCLUSION This study showed that the harvesting stage had significant effects on chemical composition and antioxidant properties of essential oils, and chamazulene is main compound for antioxidant activity in A. absinthium.

Abstract
BACKGROUND Cognitive impairment is one of the most crucial disorders among multiple sclerosis (MS) patients. Since MS is an inflammatory disease and Boswellia papyrifera has anti-inflammatory effects, the influence of B. papyrifera on cognitive impairment in MS patients has been investigated in the present study. METHODS In this clinical trial, 80 MS patients who referred to the clinic of Shafa Hospital, Kerman, Iran were selected. Having completed a written consent form, patients with relapsing remitting MS, with no occurrence of a new attack throughout 1 month before the study, with no pregnancy or breastfeeding entered the study. The patients were randomly divided into two groups; then Brief International Cognitive Assessment for MS (BICAMS) test was carried out. One group received B. papyrifera (capsule 300 mg, twice a day) while the other group received placebo with the same dose for 2 months. After 2 months of treatment, BICAMS was redone and changes were analyzed. The significant change value on the before-after BICAMS points were considered to be 8, 13, and 7 points for the symbol digit modality test (SDMT), the California verbal learning test (CVLT), and the brief visual-spatial memory test revised (BVMT-R), respectively. RESULTS The patients' mean age was 36.58 8.50 years. The mean duration of disease was 7.41 4.13 years. About 84.2% (n = 64) of the patients was female. In the BVMT-R, 13 patients (34.2%), who had already taken B. papyrifera, were shown to have significant improvement compared to the placebo group with no improvement (P < 0. 001). About 12 and 8 patients in the treatment and placebo groups in the SDMT, respectively (P = 0.200) and 17 and 12 patients in the treatment and placebo groups in the CVLT, respectively (P = 0.170) had significant change values. CONCLUSION B. papyrifera showed significant improvement in visuospatial memory, but had no effect on verbal memory and information processing speed.

Abstract
Dexamethasone concentration was measured in plasma and amniotic fluid by radioimmunoassay using a rabbit antiserum raised against DX-hemisuccinate-albumin. Recoveries of added tracers averaged 70% after paper chromatography. The within- and between-assay coefficients of variation averaged 10%. The lower limit of detection was 0.2 mug/dl when 0.4 ml of plasma was assayed. Ten healthy pregnant women at term had cesarean sections 8 to 11 hours following administration of 8 mg of DX orally. DX levels in maternal vein, in umbilical vein and artery, and in amniotic fluid averaged 2.2, 2.9, 2.6, and 2.5 mug/dl, respectively. Although cortisol levels were markedly suppressed, the total relative glucocorticoid activity in blood of fetuses treated with DX far exceeded that of the untreated group.
