Outcomes and predictors of seizure recurrence in post-stroke epilepsy, a retrospective hospital-based study.

BACKGROUND: The occurrence of seizures following a stroke is a well-recognized complication associated with a significant increase in morbidity and mortality. Despite the numerous studies examining outcomes and risk factors related to post-stroke seizures (PSS), there remains a lack of clarity regarding the clinical characteristics, treatment, and PSS recurrence (PSSR) rates in patients experiencing their initial episode of PSS. PURPOSE: This study aimed to determine the risk factors for developing recurrent seizures after first PSS and their effects on functional outcomes and mortality. METHODS: All patients underwent an electroencephalography (EEG) and were monitored for a minimum of 24 months following the first PSS. The primary endpoint was the recurrence of seizures. Predictive factors for PSSR were determined by using the Cox-proportional hazards model, and the cumulative latency of recurrence at 90, 180, 360, and 720 days was estimated using Kaplan-Meier analysis. RESULTS: Seizure recurred in 36.8% (39/106). Significant association of PSSR was noted with female gender, use of older anti-seizure medications (ASMs) (p<0.001), EEG findings as focal slow wave activity (p<0.001), Ictal epileptiform abnormalities (p=0.015), status epilepticus (p=0.015), and with severe disability (p=0.008). However, multivariate cox-proportional hazards model showed significant association of female gender (HR=3.28; 95% CI: 1.42-7.58; p=0.006). Hazard ratio (HR) was increased with older ASMs use, focal aware seizure types, Ictal EAs, and periodic discharges on EEG; though, statistically significant. CONCLUSION: Factors such as the type of ASMs, EEG findings, and seizure type were significantly linked to PSSR. Female gender was the only independent predictor established. Additionally, significant functional decline was reported with recurrence.

Frequency and characteristics of chronic fatigue syndrome in multiple sclerosis patients at a university hospital in Eastern Saudi Arabia.

BACKGROUND: Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease that affects various parts of the central nervous system. Fatigue, a common symptom, transient, prolonged, or chronic experienced by individuals with MS, can significantly impact daily functioning. It can be associated with underlying pathological processes or can have an idiopathic cause, such as chronic fatigue syndrome (CFS). The study aimed to assess the presence and etiology of fatigue in MS patients and its relationship with CFS. MATERIALS AND METHODS: This cross-sectional study was conducted in the Eastern Province of Saudi Arabia. Data were collected using a questionnaire from a sample of 225 MS patients receiving care at our university hospital. The questionnaire included the Centers for Disease Control and Prevention (CDC) criteria for diagnosing CFS and the Expanded Disability Status Scale to evaluate fatigue in MS patients. RESULTS: Of the total of 225 MS patients who participated in this study, 87.1% were diagnosed with relapsing-remitting MS, 6.7% with primary progressive MS, 3.6% with clinically isolated syndrome, and 2.7% with secondary progressive MS. About 53% had experienced fatigue that persisted for over 6 months. Analysis of CFS diagnosis revealed that 7.3% of patients met both CDC criteria and self-reported answers while 17.5% reported having CFS despite not meeting the CDC criteria. These findings highlight a significant lack of agreement between patient-reported diagnoses and established criteria, indicating poor agreement (P = 0.028). CONCLUSION: The study found an association between CFS and MS, and a significant impact on daily functioning. The study revealed lack of agreement between patient-reported diagnoses and established criteria for CFS. This emphasizes the need for a standardized approach to diagnosis and evaluation of fatigue in MS patients.

Spinal cord compression secondary to intraspinal extramedullary hematopoiesis.

Extramedullary hematopoiesis (EMH) is a rare cause of spinal cord compression (SCC) occurring in various hematological illnesses such as myeloproliferative disorders, thalassemias, and various types of anemia. EMH represents the growth of blood cells outside the bone marrow. Common EMH locations include the spleen, liver, lymph nodes, and paravertebral regions. When this occurs in the spinal cord, the mass effect can compress the spinal cord and cause different neurological symptoms depending on the area of the spinal cord affected. This report describes a 27-year-old female with a known case of beta-thalassemia major, who presented with mid-thoracic back pain, weakness, and paresthesia at the T10 level. In addition, this report illustrates the importance of considering EMH in the differential diagnosis of SCC in patients with thalassemia.

Prospective Matched Case-Control Study of Over-Early P100 Wave Latency in Migraine with Aura.

A sizable portion of the world's population suffers from migraines with aura. The purpose of this research is to describe the findings of a case-control study that was carried out to gain a better understanding of how migraine with aura manifests. The research looked at the P100 delay of the visual-evoked potential in both eyes of 92 healthy people and 44 patients who suffered from migraines with visual aura. All of the participants in the study were recruited from King Fahad University Hospital in Saudi Arabia. Both sets of people had the same ancestry and originated from the same location. Patients who suffered from migraines with aura exhibited a significantly shorter P100 delay in both eyes compared to healthy controls (p = 0.001), which is evidence that their early visual processing was distinct. In order to arrive at these findings, we compared people who suffer from migraines with aura to people who do not suffer from migraines and used them as subjects. These findings contribute to the ongoing attempts to bring the disease under control and provide vitally significant new information regarding the functioning of headaches with auras. The primary focus of study in the future should be on determining the nature of the connection between issues with early visual processing and headaches with aura.

The Effect of Multiple Sclerosis on Family Planning Among Saudi Families.

Background Multiple sclerosis (MS) is one of the most common neurological disorders in the world, and it is the leading cause of non-traumatic disability among young adults. While genetic susceptibility plays a role in MS development, the condition is not directly hereditary. Nevertheless, MS tends to aggregate within families, with first-degree relatives of affected individuals facing a higher risk than the general population. Additionally, family planning knowledge is insufficient among MS patients. Hence, this study aimed to assess the influence of MS disease on family planning and define the factors influencing decision-making regarding family planning in multiple sclerosis patients in the Eastern province of Saudi Arabia. Methodology A prospective study was conducted in Eastern Province, Saudi Arabia, during the period of 2022-2023 through directly interviewing the patients using a pre-validated questionnaire. This study would improve counseling and future care plans regarding family planning during patients' visits. Results A total of 57 women with MS were enrolled in this study; 35 (61.4%) patients got pregnant after the onset of the disease, and 46 (97.9%) had healthy children. A total of 23 (40.4%) were previously aborted due to the disease. Only five (8.8%) diseased women experienced relapses of the disease during previous pregnancies. A total of 14 (24.6%) women reported that generally their condition improved during pregnancy and childbirth, and 12 (21.1%) had no change, while four (7%) reported that their condition generally deteriorated. Also, 15 (26.3%) had no change in their condition during the first three months after birth, while four (7%) experienced deteriorated condition. Exactly 71.2% reported that the disease mostly affected their planning for pregnancy, which was of greater extent among 24.6% and partial among 14%. Conclusion Multiple sclerosis affects women's decisions regarding family planning. The most reported causes among affected women included anxiety about weakness and lack of strength during childbirth, concern about possible side effects from MS drugs on the fetus (congenital malformations), worry about not being able to take care of a child due to illness and the severe impact of the disease on their health.

Association between glycated hemoglobin and functional outcomes in patients with intracranial large artery atherosclerotic disease-related acute ischemic stroke: identifying the magic number.

Objective: This study aimed to investigate the effect of the glycated hemoglobin A1c (HbA1c) level on the functional outcome (FOC) in patients with intracranial large artery atherosclerotic disease (ICLAD)-related acute ischemic stroke (AIS). Methods: This retrospective study enrolled patients with ICLAD-related AIS who were admitted to King Fahd University Hospital between January 2017 and September 2021. Patients were divided into two groups based on the optimal cutoff HbA1c level determined using receiver operating characteristic curve analysis-those with HbA1c ≤6.9% and those with HbA1c >6.9%. Demographic and other clinical characteristics were compared between the two groups using chi-square tests. The association between HbA1c and 90-day FOC was assessed using the chi-square test and odds ratios (ORs). Multivariate analysis was performed to adjust for confounding factors. Results: A total of 140 patients were included in the analysis. A significant association was observed between the HbA1c level and FOC. Compared to patients with HbA1c ≤6.9%, patients with HbA1c >6.9% were more likely to have an unfavorable FOC [p = <0.001, OR = 2.05, 95% confidence interval (CI) = 1.33-3.14]. The association between HbA1c >6.9% and unfavorable FOC was sustained even after adjusting for confounding factors (p = 0.008) and atherosclerosis risk factors (p = 0.01). HbA1c >6.9% was also associated with higher ORs for in-hospital complications (p = 0.06, OR = 1.34, 95% CI = 1.02-1.77) and mortality (p = 0.07, OR = 1.42, 95% CI = 1.06-1.92) although these associations did not attain significant p-values. Conclusion: HbA1c >6.9% was significantly associated with unfavorable FOC in ICLAD-related AIS. However, further studies with larger sample sizes are required to verify whether HbA1c is an independent predictor of poor FOC. Nevertheless, targeting HbA1c <7% should be the goal of physicians when managing patients at high risk of ICLAD.

Estimated prevalence study of attention-deficit/hyperactivity disorder among eastern province children in the Kingdom of Saudi Arabia.

Background: Studying mental disorders in children is significantly important due to the huge suffering of educational and psychosocial impairments in adult life. Attention-deficit/hyperactivity disorder (ADHD) is considered the most common mental disorder in children, especially in early school-aged children. It manifests in about 8%-12% of children in the world. In Saudi Arabia, it affects 4%-12% of children. Objective: The study aimed to count the number of undiagnosed ADHD cases and the associated risk factors in Eastern Province in Kingdom of Saudi Arabia (KSA). Methods: A cross-sectional study was performed among girls' and boys' children aged 6-10 years old in Eastern Province in KSA with a random selection of parents. Sample size is equal to 1658. The assessment was done by an online questionnaire filled it by parents using Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnostic criteria and Connor's scale of ADHD excluding any developmental or mental disorder at the beginning of the questionnaire. Results: After excluding the participants who were diagnosed with behavioral and growth developmental disorder, the remaining 1430 have been screened for ADHD based on Connor's scale. 185 of a child out of 1430 were suggested to have ADHD, of which 10 out of them show the signs of ADHD, 76 of them have moderately severe ADHD, and 99 out of them have atypical or severe ADHD based on Connor's scale of ADHD. The study shows that there is a significant relationship between the positive screening of ADHD and gender males (71.35%), females (28.64%), family history (20.5%), nervous system diseases (4.32%), brain damage from trauma (9.72%), smoking habit of the mother (8.64%), smoking during pregnancy (3.78%), mother exposure to second-hand smoking (42.16%), child exposure to a toxic substance like lead during the early life (1.62%), and the preterm labor (15.13%). However, the study shows there is no significant relationship between the positive screening of ADHD with age, drinking alcohol, and central nervous system infection. Conclusion: The prevalence of undiagnosed ADHD is slightly high. Also, it has many causes of ADHD including gender, smoking, parental psychiatric disorders, and obstetric and pregnancy problems.

Résumé Background: L'étude des troubles mentaux chez les enfants est d'une importance considérable en raison des souffrances liées aux difficultés scolaires et psychosociales qui perdurent à l'âge adulte. Le trouble du déficit de l'attention avec hyperactivité (TDAH) est considéré comme le trouble mental le plus courant chez les enfants, notamment chez les enfants d'âge scolaire précoce. Il se manifeste chez environ 8% à 12% des enfants dans le monde. En Arabie saoudite, il touche entre 4% et 12% des enfants. Objective: L'étude visait à dénombrer le nombre de cas de TDAH non diagnostiqués et les facteurs de risque associés dans la province orientale du Royaume d'Arabie saoudite (KSA). Methods: Une étude transversale a été réalisée auprès d'enfants de filles et de garçons âgés de 6 à 10 ans dans la province orientale de l'Arabie saoudite, en utilisant une sélection aléatoire des parents. La taille de l'échantillon est égale à 1658. L'évaluation a été réalisée à l'aide d'un questionnaire en ligne rempli par les parents, en utilisant les critères diagnostiques du Manuel diagnostique et statistique des troubles mentaux, cinquième édition, ainsi que l'échelle de Connor pour le TDAH, en excluant tout trouble du développement ou trouble mental au début du questionnaire. Résultats: Après exclusion des participants ayant été diagnostiqués avec un trouble du comportement et du développement, les 1430 restants ont été dépistés pour le TDAH à l'aide de l'échelle de Connor. Parmi ces enfants, 185 ont été suggérés d'avoir un TDAH, dont 10 présentent des signes de TDAH, 76 présentent un TDAH modérément sévère et 99 présentent un TDAH atypique ou sévère selon l'échelle de Connor. L'étude révèle qu'il existe une relation significative entre le dépistage positif du TDAH et le genre masculin (71,35 %), féminin (28,64 %), les antécédents familiaux (20,5 %), les maladies du système nerveux (4,32 %), les lésions cérébrales suite à un traumatisme (9,72 %), la consommation de tabac par la mère (8,64 %), la consommation de tabac pendant la grossesse (3,78 %), l'exposition de la mère à la fumée secondaire (42,16 %), l'exposition de l'enfant à une substance toxique comme le plomb pendant la petite enfance (1,62 %) et le travail prématuré (15,13 %). Cependant, l'étude montre qu'il n'existe aucune relation significative entre le dépistage positif du TDAH et l'âge, la consommation d'alcool et les infections du système nerveux central. Conclusion: La prévalence du TDAH non diagnostiqué est légèrement élevée. De plus, il existe de nombreuses causes du TDAH, dont le genre, le tabagisme, les troubles psychiatriques des parents, ainsi que les problèmes obstétriques et durant la grossesse.

Unmet Needs and Treatment of Relapsing-Remitting Multiple Sclerosis in Saudi Arabia: Focus on the Role of Ofatumumab.

Treatment-pattern data suggest that some patients with multiple sclerosis (MS) in the Kingdom of Saudi Arabia (KSA) may not be receiving optimal treatment. A virtual meeting of ten expert Saudi neurologists, held on October 23, 2020, discussed unmet needs in relapsing-remitting MS (RRMS), and the role of ofatumumab as a suitable treatment in the KSA. Multiple unmet needs were identified: poor quality of life, with high rates of depression and anxiety; a negative impact of MS on work ability; treatment choices that may compromise efficacy for safety or vice versa; inconvenient or complex dosage regimens; and limited access to patient education and support. Early use of highly effective disease-modifying treatments (DMTs) results in better patient outcomes than starting with less effective treatments and downstream escalation, but this strategy may be underutilized in the KSA. B cells are important in MS pathogenesis, and treatments targeting these may improve clinical outcomes. Ofatumumab differs from other B cell-depleting therapies, being a fully human monoclonal antibody that binds to CD20 at a completely separate site from the epitope bound by ocrelizumab, and being administered by subcutaneous injection. When compared with teriflunomide in two randomized, phase 3 clinical trials in patients with RRMS, ofatumumab was associated with significant reductions in annualized relapse rates, rates of confirmed disability worsening, and active lesions on magnetic resonance imaging. The incidence of adverse events, including serious infections, was similar with the two treatments. Ofatumumab is a valuable first- or second-line treatment option for RRMS in the KSA, particularly for patients who would benefit from highly effective DMTs early in the disease course, and for those who prefer the convenience of self-injection. Future research will clarify the position of ofatumumab in RRMS treatment, and comparative cost data may support the broad inclusion of ofatumumab in formularies across the KSA.

A New Report of Combined Central and Peripheral Demyelination: A Case Report.

Combined central and peripheral demyelination (CCPD) is not encountered frequently in the clinical practice, and it requires a high level of suspicion for diagnosis. We describe a case of a young man who was diagnosed with radiologically isolated syndrome (RIS) after presenting initially with symptoms suggestive of central nervous system (CNS) insult in the form of double vision, slurred speech, left-sided numbness, and unsteadiness. However, on the next day of admission, his neurological examination was remarkable for ataxia, areflexia, and ophthalmoplegia, the typical triad of Miller Fisher syndrome (MFS). After confirming both diagnoses, the final diagnosis of CCPD was made. The challenges one may face to diagnose and treat CCPD urge sharing of similar cases to open the door for further extensive and thorough investigations and to encourage further studies and analysis of available data to come up with consolidated management guidelines for rare disorders.

An Observational Study Comparing the Safety and Efficacy of Conventional Anticoagulation Versus New Oral Anticoagulants in the Management of Cerebral Venous Sinus Thrombosis.

Objective: To compare the safety and efficacy of conventional anticoagulants with new oral anticoagulants (NOACs) for management of cerebral venous sinus thrombosis (CVST).Methods: This was a retrospective, prospective cohort study of patients who presented with CVST to a tertiary stroke center in the Middle East from January 2012 to October 2019. Patients with a diagnosis of CVST were identified, and data were analyzed for demographic characteristics. Specific consideration was given to compare the efficacy and safety of different anticoagulation treatments.Results: A total of 36 patients were included in the final analysis, with 15 (41%) men and 21 (59%) women and a male to female ratio of 1:1.4. Most of the patients (n = 22, 61%) were Saudi. Their ages ranged between 15 and 82 years (mean ± SD age of 34.22 ± 13.16 years). Headache was the most common feature, present in 22 (61%) of the patients, followed by unilateral weakness in 15 (41%) and cranial nerve palsies in 11 (30%). The most common etiology was prothrombotic state (both hereditary and acquired thrombophilia: n = 16, 45%). Other etiologies were postpartum state/oral contraceptive pill usage in 7 (19%), infections in 7 (19%), and trauma in 3 (8%). Most of the patients (n = 24, 67%) still received conventional anticoagulation (warfarin/low molecular weight heparin), but 9 (25%) of the patients consented to start NOACs. Efficacy (as measured by clinical improvement plus rate of recanalization of previously thrombosed venous sinuses) showed no statistically significant difference, although it proved to be better tolerated, as none of the patients stopped the treatment due to adverse events and risk of major bleeding was significantly low in the NOAC group. Nine patients in the warfarin group stopped medication, while none in the NOAC group did so (P = .034).Conclusion: NOACs were found to be at least as good as conventional anticoagulation for the management of CVST. However, efficacy was almost similar, a finding that is consistent with most of the published case series and the few recently published prospective studies. Larger prospective and population-based studies are needed to clarify our preliminary results.

When Brain Biopsy Solves the Dilemma of Diagnosing Atypical Cerebral Amyoild Angiopathy: A Case Report.

BACKGROUND Cerebral amyloid angiopathy-related inflammation (CAA-ri) is an acknowledged syndrome of reversible encephalopathy, also known as cerebral ß-related angiitis. It is characterized by brisk progressive higher mental dysfunctions, headaches, seizures/epilepsy, and behavioral changes, and is highly responsive to immunosuppressive medications. To quickly and properly determine patients' management plans and prognoses, doctors are left with only CAA-ri-associated behavioral changes and seizures, in addition to a high index of suspicion of the correct diagnosis. CASE REPORT A 67-year-old woman was presented to the emergency room (ER) with behavioral changes and seizures. Upon screening, the patient was found to have radiological evidence of asymmetrical cortical-subcortical white-matter lesions accompanied by multiple cerebral microbleeds in the background of the negative screening for infectious/neoplastic and paraneoplastic processes. After undergoing a brain biopsy, the diagnosis was confirmed to be amyloid deposition within the inflammatory vessel walls. The patient showed a dramatic improvement after methylprednisolone pulse therapy, plasma exchange, and rituximab maintenance. CONCLUSIONS We encourage and support brain biopsies to confirm highly suspicious CAA-ri atypical cases to initiate early treatment and achieve the best outcome without any further delays.

Impact of Technology Use on Behavior and Sleep Scores in Preschool Children in Saudi Arabia.

Background: Pre-school children use digital devices both at home and in kindergarten for communication. However, such technologies can also be used for creativity learning and entertainment. Technology usage might exert a negative impact on the psychosocial development of pre-school children, thus necessitating parental monitoring. Previous studies have recommended early intervention for pre-school children by decreasing the duration of digital devices, spending more time with the family, and participation in motor activities to avoid the ill effects of technology. Aim: To investigate the impact of digital device use on the behavioral and sleep scores of preschool children as perceived by parents in Saudi Arabia (SA). Method: This cross-sectional study was conducted across two regions in SA. It was ethically approved by the ethical review board of Imam Abdulrahman Bin Faisal University. The participants were randomly selected from well-baby hospital records, surveyed and interviewed to obtain data for the following measures: demographic data, technology usage, sleep disturbance scale, and behavior scale. Children with special needs or comorbidities were excluded from the study. Descriptive and multivariate regression analysis were done. Results: We recruited 288 children. Most did not attend schools (63.2%), 22.6% were in kindergarten, and 14.2% were in nursery schools. Smart phones were the most commonly used device by the children (42.4%). Most used the technology for 2-3 h/days (34%). Cartoons were the most commonly sought content (42%). The behavior scores for children aged 18-36 months showed a mean value of 5.1, 3.7, and 4.6 for surgency, negative affect, and effortful control, respectively. Children aged 3-5 years showed a mean value of 4.3, 4, and 4.7 for surgency, negative affect, and effortful control, respectively. Sleep disturbance scores for all children showed a mean value of 12.4, 3.5, 3.8, 8, 7.3, and 2.7 on disorders of initiating and maintaining sleep, sleep-breathing disorders, disorders of arousal, sleep-wake transition disorders, disorders of excessive somnolence, and sleep hyperhidrosis, respectively. The mean total sleep score was 37. Multivariate regression analysis showed significant positive relationship between surgency and three factors namely family income of 10,000-15,000 SR (t = 1.924, p = 0.045), fathers' bachelor's degrees (t = 2.416, p = 0.16), and owning a video game device (t = 2.826, p = 0.005<0.05). Negative affect was significantly associated with fathers' diploma level of education (t = 2.042, p = 0.042). Negative significant relationship between effortful control and fathers' secondary level of education (t = -2.053, p = 0.041). There was a significant negative relationship between effortful control and owning a TV and video game device (t = -2.35, -2.855, p = 0.043, 0.005<0.05, respectively). A significant positive relationship was found between child's sleeping score (worse sleep) and watching technology between 3 and 5 h (t = 2.01, p = 0.045), and mothers' unemployment status (t = 2.468, p = 0.014). Conclusion: In conclusion, technology use is associated with a negative impact on children sleep and behavior. Owning a digital device, using tablets, screen viewing for more than 3-5 h, and watching movies were significantly associated with negative child's behavior and sleep.

Postprandial fasting related headache during Ramadan in Saudi Arabia: A cross-sectional study.

BACKGROUND: Headache disorders are classified as primary or secondary; however, among the secondary headaches, those attributed to food ingestion are not well understood. Therefore, we conducted this study to describe and characterize a new headache entity that occurred during the holy month of Ramadan. This headache occurred within 4 h of breaking the fast. METHODS: This is a nationwide descriptive community-based cross-sectional study conducted during the last 10 days of Ramadan, based on a random sample of adults living in Saudi Arabia. The demographic data, headache symptomatology, nature and distribution of the pain, possible triggering and relieving factors, and patient management programs were analyzed. RESULTS: Completed questionnaires were obtained from 16,031 participants. Of those, 3147 (19.6%) reported headaches after breaking the fast in Ramadan. In 84.1% of cases, there was no previous diagnosis of headache or migraine. The characteristics of these postprandial fasting-related headaches mostly was episodic in nature (72%). The nature of the headache was variable, mostly heaviness or tightness (53.9%). Triggering factors included ingestion of fried food in (45%) and coffee (26.3%). Lying down and sleeping was found to be an important relieving factor (61%). CONCLUSION: A new headache entity is being described. Appears to be quite common, occurs less than 2 h following the first meal, and is mostly of the heaviness and tension type.

Registry of patients with multiple sclerosis and COVID-19 infection in Saudi Arabia.

BACKGROUND: The outbreak of coronavirus disease 2019 (COVID-19) has rapidly spread and developed as a pandemic threatening global health. Patients with multiple sclerosis (MS)-an autoimmune demyelinating inflammatory disease of the central nervous system (CNS)-are predominantly treated with immunomodulatory/immunosuppressive disease-modifying therapies (DMTs), which can increase the risk of infection. Therefore, there is concern that these patients may have a higher risk of COVID-19. In response to growing concerns of neurologists and patients, this study aimed to determine the prevalence, severity, and possible complications of COVID-19 infection in patients with MS in Saudi Arabia (SA). METHODS: In this prospective cohort study, demographic and clinical data were obtained from patients residing in SA with MS who had a positive result for COVID-19 per reverse transcription-polymerase chain reaction test or viral gene sequencing, using respiratory or plasma samples. Comparison of COVID-19 severity groups was performed using one-way ANOVA or Kruskal-Wallis test for numerical variables and Chi-squared test for categorical variables. RESULTS: Seventy patients with MS and COVID-19 (71% female) were included in this analysis. Of the 53 (75.7%) patients receiving a DMT at the time of COVID-19 infection, the most frequently used DMTs were fingolimod (25%) and interferon-beta (25%). Nine (13%) patients had MS relapse and were treated with intravenous methylprednisolone in the four weeks before COVID-19 infection. The most common symptoms at the peak of COVID-19 infection were fever (46%), fatigue (37%), and headache (36%). Symptoms lasted for a mean duration of 8.7 days; all symptomatic patients recovered and no deaths were reported. COVID-19 severity was categorized in three groups: asymptomatic (n = 12), mild-not requiring hospitalization (n = 48), and requiring hospitalization (n = 10; two of whom were admitted to the intensive care unit [ICU]). Between the three groups, comparison of age, body mass index , Expanded Disability Severity Score , MS disease duration, and DMT use at the time of infection showed no significant differences. A higher percentage of patients who were admitted to hospital or the ICU (40%; p = 0.026) presented with an MS relapse within the prior four weeks compared with those who were asymptomatic or had a mild infection (both 8.3%). CONCLUSION: These findings present a reassuring picture regarding COVID-19 infection in patients with MS. However, patients with MS who have had a relapse in the preceding four weeks (requiring glucocorticoid treatment) may have an increased risk of severe COVID-19.

Managing multiple sclerosis in the Covid19 era: a review of the literature and consensus report from a panel of experts in Saudi Arabia.

Disease-modifying therapies (DMT) for relapsing-remitting MS (RRMS) act on the immune system, suggesting a need for caution during the SARS-CoV2/Covid-19 pandemic. A group of experts in MS care from Saudi Arabia convened to consider the impact of Covid-19 on MS care in that country, and to develop consensus recommendations on the current application of DMT therapy. Covid-19 has led to disruption to the care of MS in Saudi Arabia as elsewhere. The Expert Panel considered a DMT's overall tolerability/safety profile to be the most important consideration on whether or not to prescribe at this time. Treatment can be started or continued with interferon beta, teriflunomide, dimethyl fumarate, or natalizumab, as these DMTs are not associated with increased risk of infection (there was no consensus on the initiation of other DMTs). A consensus also supported continuing treatment regimens with fingolimod (or siponimod) and cladribine tablets for a patient without active Covid-19. No DMT should be imitated in a patient with active Covid-19, and (only) interferon beta could be continued in the case of Covid-19 infection. Vaccination against Covid-19 is a therapeutic priority for people with MS. New treatment should be delayed for 2-4 weeks for vaccination. Where treatment is already ongoing, vaccination against Covid-19 should be administered immediately without disruption of treatment (first-line DMTs, natalizumab, fingolimod), when lymphocytes have recovered sufficiently (cladribine tablets, alemtuzumab) or 4 months after the last dose (ocrelizumab). These recommendations will need to be refined and updated as new clinical evidence in this area emerges.

No evidence of disease activity-3 (NEDA-3) status in patients with relapsing remitting multiple sclerosis: Evidence from Saudi cohort receiving mainly Interferon.

BACKGROUND: No evidence of disease activity (NEDA) is a composite surrogate assessing the responsiveness to various disease-modifying treatments (DMTs) in patients with relapsing and remitting multiple sclerosis (RRMS), addressing clinical as well as radiological disease activity. Despite the rising prevalence of multiple sclerosis in Saudi Arabia (SA), there is a lack of evidence focusing on this important aspect in the management of RRMS. This study aimed to identify the prevalence of NEDA-3 status achievement in patients with RRMS on DMTs (mainly the interferon) and to describe the factors affecting its attainment. METHOD: This was a retrospective, cross-sectional study carried out at King Fahd University Hospital after obtaining institutional ethical approval. The electronic records of 119 patients diagnosed with RRMS were reviewed. Clinical manifestations at initial presentation, relapse after starting treatment, disability progression, and development of new lesions on follow-up magnetic resonance imaging were all documented to assess NEDA-3 status. Data were analyzed using Statistical Package for Social Sciences, version 22. RESULTS: NEDA-3 status was achieved in 41 (33.6%) patients. The female-to-male ratio for all patients was 1.5:1. Interferon (IFN) was the most commonly prescribed DMT. NEDA-3 status was achieved in 30.9% of patients receiving IFN. Mean baseline Expanded Disability Status Scale in patients who did not achieve NEDA-3 was 2.8±1.8. Patients with ataxia (P = <0.001), sphincter disturbances (P=0.002) and infra-tentorial brain lesions (P=0.03) were less likely to achieve NEDA-3 status. Involvement of pyramidal, cerebellar and more than one system at initial presentation was more frequent in patients who could not achieve NEDA-3 status (P=0.002) CONCLUSION: Less than one third of total patients on IFN as DMT could achieve NEDA-3 status in our cohort of patients which is in agreement with the literature published in the West. We could not properly asses NEDA-3 status for other DMTs in our center due to the very small sample size of patients on these DMTs, and recommend future studies including larger number of patients on DMTs other than IFN. Significant differences were identified between the two groups of patients with respect to attainment of NEDA-3 status, which requires further verification by multicenter prospective studies.

Clinical presentations, radiological characteristics, and biological risk factors of cerebral venous thrombosis at a University Hospital in Saudi Arabia.

OBJECTIVES: To describe the clinical features and possible etiologies of cerebral vein thrombosis (CVT) in a Saudi Arabian cohort. METHODS: A retrospective, observational design was implemented. Data pertaining to 36 patients (19 female and 17 male) with confirmed CVT diagnosis admitted to a hospital in Saudi Arabia between 2008 and 2019 were obtained and analyzed. RESULTS: The age of patients ranged between 19 to 82 years, and the mean/median age was 33/29 years. Most commonly reported symptoms were headache ( 72%), unilateral lower limb weakness (39%), and seizures (17%). Papilledema was found in 8% of patients. Thrombotic disorders were identified in 14% and infections were identified in 8% of the patients. Two patients had ulcerative colitis, 2 were diagnosed with Behcet's disease, and 2 women were using oral contraceptive pills. Single sinus thrombosis was detected in only 22% of patients. One patient with diabetic ketoacidosis died. Thrombotic disorder was the most common risk factor, followed by that iron deficiency anemia. CONCLUSION: The transverse sinus was the most frequently thrombosed sinus. Iron deficiency anemia emerged as a predisposing preventable condition for CVT, while genetic factors were found to be less important in this cohort.

Potential of Timed 25-Foot Walk Values in Predicting Maximum Walking Distance in Persons with Multiple Sclerosis.

BACKGROUND: Expanded Disability Status Scale (EDSS) scores of 4.0 or greater are determined primarily by maximum walking distance (MWD). Estimation of MWD by persons with multiple sclerosis (MS) is often used due to the impracticality of formally walking a person with MS in a clinic setting. Previous studies have demonstrated discrepancies between estimated and actual MWDs. Whether Timed 25-Foot Walk test (T25FW) values can be used to predict MWD is currently unknown. This study aimed to determine whether T25FW time is predictive of MWD in persons with MS. METHODS: This study is a post hoc analysis of a previously described prospective cohort study. Persons with MS with an EDSS score of 3.5 to 5.5 were included. The participant's T25FW values and MWD were measured. RESULTS: Of the 38 adult participants (mean age, 50.8 years; 27 women [71%]), 24 (63%) had relapsing-remitting MS. The median EDSS score was 4.5 (range, 3.5-5.5). The T25FW times were divided into seven categories (<5.0, 5.0-5.9, 6.0-6.9, 7.0-7.9, 8.0-8.9, 9.0-9.9, and ≥10.0 seconds). The MWDs were divided into corresponding EDSS score categories: ≥500, 300-499, 200-299, 100-199, and ≤99 m. Ordinal logistic regression, when controlled for age, found the T25FW categories to be predictive of EDSS score (χ2 = 17.630, df = 7, P = .014). CONCLUSIONS: The T25FW value may be used as a surrogate estimate of MWD. Further studies are needed to confirm the reliability of the T25FW in predicting MWD.

Synthesis of Benzimidazole-Based Analogs as Anti Alzheimer's Disease Compounds and Their Molecular Docking Studies.

We synthesized 10 analogs of benzimidazole-based thiosemicarbazide 1 (a-j) and 13 benzimidazole-based Schiff bases 2 (a-m), and characterized by various spectroscopic techniques and evaluated in vitro for acetylcholinesterase (AchE) and butyrylcholinesterase (BchE) inhibition activities. All the synthesized analogs showed varying degrees of acetylcholinesterase and butyrylcholinesterase inhibitory potentials in comparison to the standard drug (IC50 = 0.016 and 4.5 µM. Amongst these analogs 1 (a-j), compounds 1b, 1c, and 1g having IC50 values 1.30, 0.60, and 2.40 µM, respectively, showed good acetylcholinesterase inhibition when compared with the standard. These compounds also showed moderate butyrylcholinesterase inhibition having IC50 values of 2.40, 1.50, and 2.40 µM, respectively. The rest of the compounds of this series also showed moderate to weak inhibition. While amongst the second series of analogs 2 (a-m), compounds 2c, 2e, and 2h having IC50 values of 1.50, 0.60, and 0.90 µM, respectively, showed moderate acetylcholinesterase inhibition when compared to donepezil. Structure Aactivity Relation of both synthesized series has been carried out. The binding interactions between the synthesized analogs and the enzymes were identified through molecular docking simulations.

Influence of Sex Difference on Distribution of Risk Factors and Etiologic Subtypes of Acute Ischemic Stroke: Reality of Facts.

BACKGROUND AND PURPOSE: Sex-related differences have been documented in risk factors distribution, etiologic subtypes, diagnostic evaluation, offered management, and outcome of patients with acute ischemic stroke (AIS) from all over the world. Nevertheless, studies from Saudi Arabia are lacking. This study aimed to investigate the influence of sex on distribution of risk factors and etiologic subtype of AIS in patients admitted to our hospital. MATERIALS AND METHODS: Record of patients admitted to King Fahd Hospital of the University between 2010 and 2017 with ischemic stroke (IS) were reviewed. Base line characteristics, risk factors, and etiologic subtypes according to Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification were compared between men and women. RESULTS: Among 453 patients with IS, 300 (66.2%) were men and 153 (33.7%) were women. The mean age of all patients was 61.5 ± 14.5 years. Women were older than men (P = 0.00). Hypertension (P = 0.00), atrial fibrillation (P = 0.00), and past history of stroke (P = 0.03) were more frequent in women compared to men. Fewer carotid Doppler studies (47.1 vs. 68.3%, P = 0.00) and echocardiogram (75.1 vs. 83%, P = 0.01) were done in women as compared to men. Cardioembolic etiologic subtype (26.1 vs. 17.7%) was found more frequently, whereas small vessel occlusive (23.5 vs. 31%) and large artery disease less (10.5 vs. 16.3%) frequently in women. CONCLUSION: Significant sex-related differences were found in risk factors and subtypes of AIS in our cohort of patients. Findings of our study are in general comparable with studies from all over the world.
