The Effect of Smoking on Inactivated and mRNA Vaccine Responses Applied to Prevent COVID-19 in Multiple Sclerosis.

Introduction: Coronavirus disease 2019 (COVID-19) is the biggest health challenge of recent times. Studies so far reveal that vaccination is the only way to prevent this pandemic. There may be factors that decrease or increase vaccine effectiveness. In multiple sclerosis (MS), some of these factors may cause changes in the effectiveness of the vaccine, depending on the nature of the disease and disease-modifying treatments (DMT). In this study, we aimed to investigate the relationship between antibody titer and smoking in non-treated and DMT-treated MS patients who received inactivated vaccine (Sinovac) and messenger RNA BNT162b2 (BioNTech) mRNA vaccines. Method: Vaccine antibody responses were measured between 4-12 weeks after two doses of inactivated vaccine and mRNA vaccines. Patients were separated into 6 groups as: patients with MS without treatment PwMS w/o T, ocrelizumab, fingolimod, interferons (interferon beta-1a and interferon beta-1b), dimethyl fumarate, and teriflunomide. Antibody titers of smokers and non-smokers were compared for both vaccines and for each group. Results: The study included 798 patients. In the mRNA vaccine group, smokers (n=148; 2982±326 AU/mL) had lower antibody titers compared to the non-smokers (n=244; 5903±545 AU/mL) in total (p=0.020). In the inactivated vaccine group, no significant difference was detected between smokers (n=136; 383±51 AU/mL) and non-smokers (n=270; 388±49 AU/mL) in total (p=0.149). In both vaccine groups, patients receiving ocrelizumab and fingolimod had lower antibody titers than those receiving other DMTs or PwMS w/o T. In untreated MS patients, antibody levels in smokers were lower than in non-smokers in the mRNA vaccine group. No difference was found between antibody levels of smokers and non-smokers in any of the inactivated vaccine groups. Conclusion: Ocrelizumab and fingolimod have lower antibody levels than PwMS w/o T or other DMTs in both mRNA and inactivated vaccine groups. Smoking decreases antibody levels in the mRNA vaccine group, while it has no effect in the inactivated vaccine group.

Comparison of multiple sclerosis patients with or without rebound activity after fingolimod cessation: Five-year clinical outcomes.

BACKGROUND: Patients with multiple sclerosis (MS) who discontinue fingolimod might present with rebound activity. The reasons for the development of rebound have been identified, but there are limited data on the long-term clinical outcomes of these patients. This study aimed to compare the long-term outcomes of patients with MS with and without rebound activity after fingolimod discontinuation. METHODS: A total of 31 patients who discontinued fingolimod for various reasons with a minimum follow-up of 5 years were included in the study. Of these, 10 were assigned to the rebound group and 21 to the non-rebound group. Clinical and demographic data and 5-year clinical outcomes of both groups were prospectively examined. RESULTS: At fingolimod initiation, there were no significant differences in age, disease duration, and Expanded Disability Status Scale (EDSS) score. The annualized relapse rate (ARR) was significantly higher in the rebound group than in the non-rebound group before the fingolimod treatment (p = 0.005). In the rebound group, EDSS scores 2 months after rebound treatment and at the 5-year follow-up were not significantly different than before fingolimod initiation (p = 0.14 and p = 0.46, respectively). The last recorded EDSS was significantly higher in the non-rebound group than in the rebound group (3.6 ± 2.3 vs. 2.15 ± 1.4, p = 0.045). At the last follow-up, one patient was diagnosed with secondary progressive multiple sclerosis in the rebound group (10%), and 11 patients were in the non-rebound group (52.4%, p = 0.05). CONCLUSION: When rebound activity is well-monitored and treated after fingolimod discontinuation, no overall EDSS change is expected in the long-term follow-up.

Prospective outcome analysis of multiple sclerosis cases reveals candidate prognostic cerebrospinal fluid markers.

BACKGROUND: Predicting the long-term disability outcomes of multiple sclerosis (MS) cases is challenging. OBJECTIVE: We prospectively analysed our previous MS cohort with initial cerebrospinal fluid (CSF) proteomics data to reveal disability markers after 8.2±2.2 years of follow-up. METHODS: Patients with regular follow-up visits were assigned into two groups: those with an age-related MS severity (ARMSS) score ≥5 (unfavourable course group, N = 27) and ARMSS score <5 (favourable course group, N = 67). A machine learning-based algorithm was applied to reveal candidate poor prognosis-associated initial CSF proteins, which were measured in an independent MS cohort (verification group, N = 40) by ELISA. Additionally, the correlation of initial clinical and radiological parameters with long-term disability was analysed. RESULTS: CSF alpha-2-macroglobulin (P = 0.0015), apo-A1 (P = 0.0016), and haptoglobin (P = 0.0003) protein levels, as well as cerebral lesion load (>9 lesions) on magnetic resonance imaging, gait disturbance (P = 0.04), and bladder/bowel symptoms (P = 0.01) were significantly higher in the unfavourable course group than in the favourable course group. Optic nerve involvement evident on initial magnetic resonance imaging (P = 0.002) and optic neuritis (P = 0.01) were more frequent in the favourable course group. CONCLUSION: The herein identified initial CSF protein levels, in addition to the clinical and radiological parameters at disease onset, have predictive value for long-term disability in MS cases.

mRNA versus inactivated virus COVID-19 vaccines in multiple sclerosis: Humoral responses and protectivity-Does it matter?

BACKGROUND: COVID-19 vaccines are recommended for people with multiple sclerosis (pwMS). Adequate humoral responses are obtained in pwMS receiving disease-modifying therapies (DMTs) after vaccination, with the exception of those receiving B-cell-depleting therapies and non-selective S1P modulators. However, most of the reported studies on the immunity of COVID-19 vaccinations have included mRNA vaccines, and information on inactivated virus vaccine responses, long-term protectivity, and comparative studies with mRNA vaccines are very limited. Here, we aimed to investigate the association between humoral vaccine responses and COVID-19 infection outcomes following mRNA and inactivated virus vaccines in a large national cohort of pwMS receiving DMTs. METHODS: This is a cross-sectional and prospective multicenter study on COVID-19-vaccinated pwMS. Blood samples of pwMS with or without DMTs and healthy controls were collected after two doses of inactivated virus (Sinovac) or mRNA (Pfizer-BioNTech) vaccines. PwMS were sub-grouped according to the mode of action of the DMTs that they were receiving. SARS-CoV-2 IgG titers were evaluated by chemiluminescent microparticle immunoassay. A representative sample of this study cohort was followed up for a year. COVID-19 infection status and clinical outcomes were compared between the mRNA and inactivated virus groups as well as among pwMS subgroups. RESULTS: A total of 1484 pwMS (1387 treated, 97 untreated) and 185 healthy controls were included in the analyses (male/female: 544/1125). Of those, 852 (51.05%) received BioNTech, and 817 (48.95%) received Sinovac. mRNA and inactivated virus vaccines result in similar seropositivity; however, the BioNTech vaccination group had significantly higher antibody titers (7.175±10.074) compared with the Sinovac vaccination group (823±1.774) (p<0.001). PwMS under ocrelizumab, fingolimod, and cladribine treatments had lower humoral responses compared with the healthy controls in both vaccine types. After a mean of 327±16 days, 246/704 (34.9%) of pwMS who were contacted had COVID-19 infection, among whom 83% had asymptomatic or mild disease. There was no significant difference in infection rates of COVID-19 between participants vaccinated with BioNTech or Sinovac vaccines. Furthermore, regression analyses show that no association was found regarding age, sex, Expanded Disability Status Scale score (EDSS), the number of vaccination, DMT type, or humoral antibody responses with COVID-19 infection rate and disease severity, except BMI Body mass index (BMI). CONCLUSION: mRNA and inactivated virus vaccines had similar seropositivity; however, mRNA vaccines appeared to be more effective in producing SARS-CoV-2 IgG antibodies. B-cell-depleting therapies fingolimod and cladribine were associated with attenuated antibody titer. mRNA and inactive virus vaccines had equal long-term protectivity against COVID-19 infection regardless of the antibody status.

Retrospective analysis of effectiveness of fingolimod in real life setting in Turkey (REFINE).

BACKGROUND: During multiple sclerosis (MS) treatment different modes of action such as lateral (interferon beta to glatiramer acetate or glatiramer acetate to interferon beta) or vertical (interferon beta/glatiramer acetate to fingolimod) drug switch can be performed. This study aims to investigate the clinical effectiveness of switching from the first-line injectable disease modifying treatments (iDMTs) to fingolimod (FNG) compared to switching between first-line iDMTs. METHODS: This is a multicenter, observational and retrospective study of patients with relapsing-remitting MS who had lateral and vertical switch. The observation period included three key assessment time points (before the switch, at switch, and after the switch). Data were collected from the MS patients' database by neurologists between January 2018 and June 2019. The longest follow-up period of the patients was determined as 24 months after the switch. RESULTS: In 462 MS patients that were included in the study, both treatments significantly decreased the number of relapses during the postswitch 12 months versus preswitch one year while patients in the FNG group experienced significantly fewer relapses compared to iDMT cohort in the postswitch 12 months period. FNG cohort experienced fewer relapses than in the iDMT cohort within the postswitch 2 year. The mean time to first relapse after the switch was significantly longer in the FNG group. DISCUSSION: The present study revealed superior effectiveness of vertical switch over lateral switch regarding the improvement in relapse outcomes. Patients in the FNG cohort experienced sustainably fewer relapses during the follow-up period after the switch compared the iDMT cohort. Importantly, switching to FNG was more effective in delaying time to first relapse when compared with iDMTs.

Ocrelizumab in pediatric multiple sclerosis.

BACKGROUND: Ocrelizumab is a recombinant humanized anti-CD20 monoclonal IgG1, approved by FDA and EMA for adult patients with multiple sclerosis (MS). The data on the efficacy and safety of Ocrelizumab for pediatric MS cases are limited. OBJECTIVE: Here, we describe pediatric relapsing-remitting MS (P-RRMS) cases who were treated with Ocrelizumab as a disease-modifying drug. METHOD: P-RRMS cases who were started Ocrelizumab below 18 years-of-age and followed-up >12 months with Ocrelizumab treatment were included. The primary end-points were annualized relapse rate (ARR) and magnetic resonance imaging (MRI) activity (new/enlarging T2 lesions and new gadolinium (Gd) enhancing lesions). The secondary end-points were the percentage of patients who remain relapse-free and/or free from Gd enhancing lesions, Expanded Disability Status Scale (EDSS) score, and the safety profile of Ocrelizumab. RESULTS: Of 18 P-RRMS cases receiving Ocrelizumab, 10 patients fulfilled the inclusion criteria for our study. The median duration of follow-up under Ocrelizumab was 28,3 months (min: 15 months, max: 46 months). Mean ARR decreased from 2.01 (±0.71) to 0 during the follow-up of Ocrelizumab treatment (P < 0.0001). None of the patients had MRI activity during the treatment. Mean EDSS decreased from 1.75 (±1.09) to 1.20 (±0.63) from the initiation of Ocrelizumab to the last follow-up of the patients (P = 0.024). None of the patients had serious side effects, except one patient who experienced anaphylaxis. CONCLUSION: Ocrelizumab can be considered a safe and effective treatment option in highly active P-RRMS.

A review of rheumatoid meningitis with case studies.

Rheumatoid arthritis (RA) is an autoimmune disease involving synovial joints, and it is known that extra-articular manifestations that may affect the central and peripheral nervous systems may develop during its course. Rheumatoid meningitis is very rare among all neurological involvements. In this study, cases diagnosed as rheumatoid meningitis with clinical, imaging, laboratory, and histopathological features are presented, and the aim of the study is to present current approaches in the diagnosis and treatment of rheumatoid meningitis in the light of case studies and current literature. The data of the patients who were followed up with the diagnosis of rheumatoid meningitis in neurology clinic between 2017 and 2021 were reviewed retrospectively. Three cases diagnosed with rheumatoid meningitis are presented in detail. In the first case, the diagnosis was reached by clinical, imaging, and laboratory findings as well as treatment response, while the diagnosis was made by histopathological verification in the second case. The third case shows that spontaneous remission can be observed in the course of rheumatoid meningitis. Rheumatoid meningitis, which is one of the rarest involvements in the course of RA, may present with headaches, focal neurological deficits, seizures, and altered consciousness. A meningeal biopsy is recommended when the differential diagnosis cannot be ruled out with imaging and laboratory findings. In the differential diagnosis Mucobacterium tuberculosis, syphilis, neuro-sarcoidosis, immunoglobulin G4-related disease, lymphoproliferative diseases, and systemic metastasis should be kept in mind. Aggressive RA management is recommended for treatment.

Analysis of determinants of treatment change in adult paediatric-onset MS patients.

BACKGROUND: Paediatric-onset multiple sclerosis (POMS) is increasing worldwide and represents approximately 5% of all MS cases. Although this patient group has similar characteristics to the adult group, it is important for this patient group to receive effective treatment due to the early onset of cognitive involvement, higher lesion burden, and secondary progression at an earlier age than adults. In this study, we aimed to evaluate the factors that cause treatment change in POMS patients. MATERIAL AND METHOD: Adult patients with a first MS attack at age 18 years or younger who were followed up with the diagnosis of MS at the Clinical Neuroimmunology and Demyelinating Diseases outpatient clinic of Cerrahpasa Medical School between 1987 and 2020 were included in our study. Patient files were reviewed retrospectively, and demographic and clinical characteristics, imaging, first attack characteristics, and treatment change were noted. We included 269 patients with a definite diagnosis of MS in the study, and these patients were evaluated in two groups: negative for treatment change and positive for treatment change. RESULTS: Multifocal involvement was detected more frequently in the group with treatment change (p = 0,049). Cerebellar involvement as a first attack symptom was more common in male patients (p = 0,023) The age at first MS attack was found to be younger (p = 0,006), and the disease duration was longer in the positive for treatment change group (p = 0,003). Spinal cord involvement was more common in the positive for treatment change group (p = 0,016). Abnormal VEP findings were observed more frequently in the group without treatment change (p = 0.018). In multivariant analysis, spinal cord involvement, younger age at first attack, and abnormal VEP findings in the group without treatment change were found to be significant. Among the reasons for treatment change, the most common reason was radiological and clinical progression. CONCLUSION: The higher inflammatory load in POMS patients compared with adults necessitates early initiation of treatment in this group and timely treatment change to prevent disability. Furthermore, this patient group should be followed closely and receive effective treatment.

Treatment of multiple sclerosis-related trigeminal neuralgia with onabotulinumtoxinA.

BACKGROUND: The effectiveness of onabotulinumtoxinA (BTX-A) has been established in primary trigeminal neuralgia (TN). However, to the best of our knowledge, the efficacy of BTX-A in secondary TN has not yet been studied. OBJECTIVE: This study aimed to investigate the efficacy of BTX-A treatment in patients with multiple sclerosis-related trigeminal neuralgia (TN-MS) and compare the efficacy of BTX-A treatment between patients with primary trigeminal neuralgia (TN-P) and patients with TN-MS. METHODS: This was a retrospective medical record-review study. Demographic and clinical features and severity and frequency of pain before and 2 weeks after the BTX-A administration were extracted from the patient files. BTX-A was injected into the painful area subcutaneously and/or submucosally. BTX-A injections were performed by the same physician using the same methods. A reduction in severity and/or frequency of pain ≥50% was considered therapeutic efficacy. RESULTS: Fifty-three patients were included in this study. We classified 22 (42%) as TN-P and 31 (58%) as TN-MS. Treatment with BTX-A was effective in 16 of 31 (52%) patients with TN-MS and 10 of 22 (45%) with TN-P. BTX-A treatment was less effective in patients with a history of interventional treatments and more effective in patients with concomitant continuous pain (p = 0.007; odds ratio [OR]: 0.020-0.53 and p = 0.047; OR: 0.046-0.98, respectively). CONCLUSION: The BTX-A treatment was found to be effective in at least half of our cohort with TN-MS. Concomitant continuous pain and history of interventional treatments to the trigeminal nerve or ganglion might be predictive factors for the efficacy of BTX-A treatment.

Investigating the role of common and rare variants in multiplex multiple sclerosis families reveals an increased burden of common risk variation.

Many multiple sclerosis (MS)-associated common risk variants as well as candidate low-frequency and rare variants have been identified; however, approximately half of MS heritability remains unexplained. We studied seven multiplex MS families, six of which with parental consanguinity, to identify genetic factors that increase MS risk. Candidate genomic regions were identified through linkage analysis and homozygosity mapping, and fully penetrant, rare, and low-frequency variants were detected by exome sequencing. Weighted sum score and polygenic risk score (PRS) analyses were conducted in MS families (24 affected, 17 unaffected), 23 sporadic MS cases, 63 individuals in 19 non-MS control families, and 1272 independent, ancestry-matched controls. We found that familial MS cases had a significantly higher common risk variation burden compared with population controls and control families. Sporadic MS cases tended to have a higher PRS compared with familial MS cases, suggesting the presence of a higher rare risk variation burden in the families. In line with this, score distributions among affected and unaffected family members within individual families showed that known susceptibility alleles can explain disease development in some high-risk multiplex families, while in others, additional genetic contributors increase MS risk.

The frequency and related factors of primary headaches in patients with Hashimoto thyroiditis.

OBJECTIVES: The purpose of this study was to evaluate the incidence of primary headache and potential biomarkers in patients diagnosed with Hashimoto thyroiditis. METHODS: Patients with Hashimoto thyroiditis referred to the outpatient endocrinology clinic were included in the study. The demographic data, thyroid function test results, and autoantibody titers were recorded. The headache's clinical characteristics were also determined. The same researcher used the visual analog scale for headache severity rating in all patients. RESULTS: 155 patients with Hashimoto thyroiditis were included the study. There were 95 (61.3%) cases diagnosed with headache consisting of 20 (21.1%) migraine cases, 17 (17.9%) tension type headaches (TTHs), and 20 (21.1%) new daily persistent headaches (NDPHs). 38 of 155 (24.5%) had hypothyroidism related headaches (HRHs). There was no statistically significant relationship between the headache type and a high blood antibody level anti thyroid peroxidase antibody (p=0.135), while a positive correlation was found with thyroid stimulating hormone (TSH) (p<0.001). Hashimoto patients with migraine (n=14, 70.0%) were found to have higher blood antibody levels, while these ratios were found as 86.8% (n=33) in HRH-patients, 76.5% (n=13) in TTH-patients, and 60.0% (n=12) in NDPH-patients. 86 of 155 (55.5%) patients reported new onset headaches after a Hashimoto's thyroiditis diagnosis, and the headaches persisted without hormone therapy in 48 (84.2%) of these patients. These patients diagnosed with primary headache and this was interpreted as demonstrating comorbidity between Hashimoto's disease and primary headaches. CONCLUSION: Detection of only the relationship between TSH level and headache suggested that different mechanisms play a role in the pathophysiology. In the diagnosis of primary headache, it is important to look into secondary reasons.

Safety of SARS-CoV-2 vaccination in patients with Behcet's syndrome and familial Mediterranean fever: a cross-sectional comparative study on the effects of M-RNA based and inactivated vaccine.

Most of the published data relate to classical forms of rheumatic diseases (RD) and information on rare inflammatory disorders such as Behçet's syndrome (BS) and familial Mediterranean fever (FMF) is limited. We studied the frequency of side effects and disease flares after COVID-19 vaccination with either Pfizer/BioNTech or Sinovac/CoronaVac in 256 patients with BS, 247 with FMF, and 601 with RD. Telephone interviews were conducted using a questionnaire survey in a cross-sectional design in patients with BS, FMF, and RD followed by a single university hospital. Study participants were vaccinated either with CoronaVac (BS:109, FMF: 90, and RD: 343,) or BioNTech (BS: 147, FMF: 157 and RD: 258). The majority have received double dose (BS: 94.9%, FMF 92.3% and RD: 86.2%). BioNTech ensured a significantly better efficacy than CoronaVac against COVID-19 in all patient groups (BS: 1.4% vs 10.1%; FMF: 3.2% vs 12.2%, RD:2.7% vs 6.4%). Those with at least one adverse event (AE) were significantly more frequent among those vaccinated with BioNTech than those with CoronaVac (BS: 86.4% vs 45%; FMF: 83.4% vs 53.3%; and RD: 83.3% vs 45.5%). The majority of AEs were mild to moderate and transient and this was true for either vaccine. There were also AEs that required medical attention in all study groups following CoronaVac (BS: 5.5%, FMF: 3.3%, and RD:2.9%) or BioNTech (BS: 5.4%, FMF: 1.9%, and RD: 4.7%). The main causes for medical assistance were disease flare and cardiovascular events. Patients with BS (16.0%) and FMF (17.4%) were found to flare significantly more frequently when compared to those with RD (6.0%) (p < 0.001). This was true for either vaccine. BS patients reported mainly skin-mucosa lesions; there were however, 11 (4.3%) who developed major organ attack such as uveitis, thrombosis or stroke. Flare in FMF patients were associated mainly with acute serositis with or without fever. Arthralgia/arthritis or inflammatory back pain were observed mainly in the RD group. Our study demonstrates that BS and FMF patients vaccinated with either CoronaVac or BioNTech demonstrated similar AE profile and frequency compared to RD patients. AEs that required physician consultation or hospitalization occurred in all study groups after either CoronaVac or BioNTech. Increased frequency of flares in BS and FMF compared to that seen in RD might reflect defects in innate immunity and deserves further investigation. Caution should be required when monitoring these patients after vaccination.

Determinants of Disability in Progressive Onset Multiple Sclerosis.

Introduction: To describe the clinical and socio-demographic profiles of the patients with the progressive onset Multiple Sclerosis (MS) and to explore the determinants of disability. Method: This is a retrospective study, which was conducted in a university hospital. Patients with a progressive clinical course at onset were included in the study. In the first analysis, the clinical and demographic properties of the cohort were defined. In the second analysis the effects of age, sex, clinical activity during course, initial clinical symptoms and cerebrospinal fluid analyses on the course were evaluated. Results: Clinical activity during the course, older age, male gender, medulla spinalis involvement at onset and detection of paraparesis at initial neurological examination was found as a poor prognostic factor. Conclusion: This research confirms previous findings of the studies conducted in populations of Europe and America. Further studies are needed to confirm and validate these findings and to provide greater insight into the effects of ethnic or geographical differences on the course.

Analysis of neurology consultations in hospitalized patients with COVID-19.

OBJECTIVE: The aim of this study was to evaluate patients who were hospitalized with a diagnosis of COVID-19 and were consulted by neurology during their hospital stay. METHODS: All files of patients with COVID-19 who were admitted to Cerrahpasa Medical Faculty Hospital between March 11th and December 31st, 2020 were retrospectively reviewed, and files of patients who consulted by neurology during their stay were included. Demographic and clinical characteristics, neurologic diagnosis, outcome and related laboratory data were extracted from electronic medical records and analyzed. Patients were categorized into the first wave and second wave according to the date of hospitalization. RESULTS: A total of 2257 patients were hospitalized for COVID-19; among them, 127 were consulted by a neurologist during their hospital stay. Fifteen patients received a consultation for possible drug interactions. Among the remaining 112 patients, the reason for neurology consultation was i. exacerbation of a neurological comorbidity vs ii. new-onset neurological manifestations. The median age was 68.5 ± 14.2 years, and 60.7% were men. Dementia and stroke were the leading neurological comorbidities. COVID-19 disease was more severe in the patients with the new-onset neurological comorbidity than in patients with exacerbation of a neurological comorbidity (p = 0.07). Serum creatinine kinase levels were higher in the new-onset patient group (p < 0.05). Exacerbation of previous neurological disease or new neurological impairment were jointly and severely related to high mortality (overall 35/112 vs 275/2145, p < 0.001; exacerbation 12/45 vs 275/2145 p < 0.01; new-onset 23/67 vs 275/2145, p < 0.001). CONCLUSION: Serious neurological involvement is relatively uncommon in hospitalized patients with COVID-19 and is associated with increased mortality.

Parry-Romberg syndrome: is it a "relapsing-remitting" disease?

Parry-Romberg syndrome, also known as progressive hemifacial atrophy, is a rare, slowly progressive disorder characterized by unilateral, painless atrophy of the skin and subcutaneous tissue of the face. Neurological manifestations such as epilepsy, migraine and trigeminal neuralgia are relatively common and accompany in 15-20% of cases. Various etiologies such as infection, trauma, embryonic developmental dysfunction, sympathetic dysfunction and autoimmune disorders have been suggested as possible causes. Here we describe a 37-year-old woman whose disease manifested with dynamic contrast enhanced white matter changes over a period of two years, suggesting a "relapsing-remitting" course. Besides the inflammatory activity, positive serum-autoantibodies, inflammatory findings in cerebrospinal fluid, and an overlapping systemic autoimmune disorder may further support the hypothesis of autoimmune-inflammatory mediated pathogenesis.

The efficiency of mirror therapy on drop foot in Multiple Sclerosis Patients.

INTRODUCTION: Although the effectiveness of mirror therapy (MT) has been proved in stroke persons, there is no scientific evidence about the results in people with multiple sclerosis. The aim was to investigate whether adding MT to exercise training and neuromuscular electrical stimulation (NMES) has any effect on clinical measurements, mobility, and functionality in people with multiple sclerosis (MS). METHODS: Ambulatory people with MS, with unilateral drop foot, were included. MT group (n = 13) applied bilateral ankle exercise program with mirror following NMES for 3 days a week at hospital and exercise program for 2 days a week at home. Control group (n = 13) performed same treatment without mirror box (6 weeks). The later 6 weeks both groups performed only exercise program. Clinical measurements included proprioception, muscle tone of plantar flexor muscles (MAS), muscle strength of dorsiflexor, ankle angular velocity, and range of motion (ROM) of ankle. Functionality (Functional Independence Measurement-FIM), mobility (Rivermead Mobility Index-RMI), ambulation (Functional Ambulation Scale-FAS), duration of stair climb test, and 25-foot walking velocity were assessed at the beginning, in 6th and 12th weeks. RESULTS: More positive improvements were obtained in MT group than control group in terms of range of motion (0.012), muscle strength (0.008), proprioception (0.001), 25 feet walking duration (0.015), step test duration (0.001), FAS (0.005), RMI (0.001), and FIM (0.001) after 6 weeks treatment. It was seen that this improvement maintained to 12th week on all clinical and functional measurements (p < .05). CONCLUSION: The trial revealed that adding MT to exercise training and NMES has more beneficial effects on clinical measurements, mobility, and functionality in people with multiple sclerosis with unilateral drop foot.

Sex Differences of Migraine: Results of a Nationwide Home-based Study in Turkey.

INTRODUCTION: The prevalence of migraine was found to be more than three-fold higher in women as compared with men, and in addition to differences in prevalence rates, the characteristics and associated features might also differ between the sexes. The aim of this study was to compare sex-specific features of migraine and demographic parameters in a nationwide population-based study in Turkey. METHODS: Among 5323 subjects, a total of 871 patients who were diagnosed as having definite migraine according to the diagnostic criteria of the International Classification of Headache Disorders-III (ICHD-III) were included in our study. The demographic characteristics, associated features, and triggers of migraine were examined with regard to sex. RESULTS: The study group comprised 640 women (73.5%) and 231 men (26.5%), with a female to male ratio of 2.8:1. Attack duration, mean migraine disability assessment scores (MIDAS), frequencies of nausea, vomiting, osmophobia, vertigo/dizziness, and allodynia were found significantly different between women and men. When we compared these parameters between men and postmenopausal women, all these parameters were still significant except nausea. Odor was statistically more frequent as a reported trigger in women, whereas excessive sleep was a statistically more frequent triggering factor in men. The rates of depression and allergy were significantly higher in women when compared with men. CONCLUSION: Longer attack duration, higher MIDAS scores, and the frequencies of nausea, vomiting, osmophobia, vertigo/dizziness, and allodynia were more significant in women and this variance in sex persisted after menopause. Also, some trigger factors and co-morbidities differed between the sexes. These findings might result from complex genetic factors besides sociocultural influences, biologic, and sociocultural roles. Future studies should continue to explore biologic and genetic factors with respect to sex in migraine.

Co-existence of multiple sclerosis and anti-NMDA receptor encephalitis: A case report and review of literature.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a serious autoimmune disorder characterized by psychiatric symptoms, seizures and movement disorder. Predisposing factors have been reported since the time it was described, and its pathophysiology has been tried to be clarified over the years. Although overlap with other demyelinating diseases had been reported, such an association between Multiple Sclerosis (MS) anti ANTI-NMDAR encephalitis is limited to only a few case reports. In this article, a patient diagnosed with relapsing remitting multiple sclerosis (RRMS) for ten years who then developed NMDA-R encephalitis while on disease modifying treatment will be presented and possible common pathophysiology with previously reported literature will be discussed.

The persistence versus interchangeability of migraine and tension-type headaches in a 5-year population-based validated survey.

OBJECTIVE: The aim of this population-based validated study was to determine the course of tension-type headache and migraine and to evaluate the predictors of persistence. METHODS: We evaluated the course of headache in a large population from the first assessment in 2008 through a second assessment in 2013. Then we examined the factors associated with persistent migraine and persistent tension-type headache. RESULTS: Our study in 2013 revealed that only 42.9% of definite migraineurs in 2008 received the same diagnosis again, and of the remaining migraineurs 23.3% were newly diagnosed as definite tension-type headache; 11.6% evolved into probable tension-type headache, 6.4% changed to probable migraine, and 15.8% were headache free. The 17.7% of patients with definite tension-type headache in 2008 were newly diagnosed as having probable tension-type headache, 14.7% as having definite migraine, 6.4% as having probable migraine, and 28.9% as headache free in 2013, and only 32.3% received the definite tension-type headache diagnosis again. Binary logistic regression analysis showed nausea, throbbing and severe headache were the significant parameters for persistent migraine. A multiple regression analysis model with stepwise variable selection revealed that nausea, throbbing and severe headache and osmophobia remained in the final model as predictors of migraine persistence. We found no predictive factor for persistent tension-type headache. CONCLUSION: Migraine and tension-type headache did not seem to show a simple bidirectional linear worsening from headache-free state to definite migraine or vice versa, hence the transitions between them are more chaotic, reflecting that there are still unknown modifiers and modulators. Certain headache characteristics of migraine might predict persistent migraine.
