RESUMEN

OBJECTIVE: No data exist regarding the impact of the lockdown due to the COVID-19 pandemic on the risk factors of sudden unexpected death in epilepsy (SUDEP). This study aimed to stratify risk factors of SUDEP in relation to COVID-19 lockdown, among patients with epilepsy (PWE) in Cairo University epilepsy unit (CUEU). Therefore, we can detect risk factors and mitigate such factors in the second wave of the virus. METHODS: an observational, cross-sectional study carried on 340 Egyptian patients with active epilepsy. Individual risk identification and stratification was done by using The SUDEP and seizure Safety Checklist, after which sharing risk knowledge to PWE and their caregivers was undertaken. RESULTS: The mean age of patients was 29.72 ± 12.12. The median of the static factors was 4 (IQR 3-5) whereas, the median of the modifiable factors was 2 (IQR 1-3). Epilepsy emergencies (serial seizures or status epilepticus) were reported in 24.1 % of patients, for which non-compliance was the commonest cause, followed by deferral of epilepsy surgery for patients with drug resistant epilepsy (DRE). Stepwise logistic regression analysis showed that use of anxiolytic medications, non-compliance, keeping patients with DRE on dual anti-seizure medications (ASMs), or adding third medication increased the odds of increased seizure frequency by 2.7, 3.5, 16.6 and 6.1 times, respectively. CONCLUSION: Some COVID-19 related issues had influenced the risk of seizure worsening including postponing epilepsy surgery for patients with DRE, non-compliance, and psychiatric comorbidities. Special attention should be paid to these issues to mitigate the risk of SUDEP.

RESUMEN

BACKGROUND: In Egypt, the characterization of Neuromyelitis Optica Spectrum Disorder (NMOSD) is lacking. OBJECTIVES: To determine the demographics, clinical features, aquaporin4 antibodies (AQP4-IgG) status, and neuroimaging of Egyptian NMOSD patients. METHODS: Retrospective analysis of 70 NMOSD patients' records from the MS clinic, Kasr Alainy hospital, between January 2013 and June 2018. RESULTS: Patients' mean age was 34.9 ± 9.2 years, and the mean at disease onset was 28.9 ± 10.5 years. Fifty-nine patients had an initial monosymptomatic presentation. AQP4-IgG was measured using either enzyme-linked immunosorbent assay (ELISA) (22 patients) or cell-based assay (CBA) (34 patients). Six and 29 patients had positive results, respectively (p < 0.001). 84% had typical NMOSD brain lesions. Longitudinally extensive myelitis was detected in 49 patients, and 9 had either short segments or normal cords. Treatment failure was higher in seropositive patients. Rituximab significantly reduced the annualized relapse rate (ARR) compared to Azathioprine with a percentage reduction of (76.47 ± 13.28) and (10.21 ± 96.07), respectively (p = 0.04). Age at disease onset was the only independent predictor for disability (p < 0.01). CONCLUSION: Treatment failure was higher in seropositive patients. However, there was no difference in clinical or radiological parameters between seropositive and seronegative patients. Patients, who are polysymptomatic or with older age of onset, are predicted to have higher future disability regardless of the AQP4-IgG status.

RESUMEN

Background: Studies have shown that interferon-beta (IFN-ß) treatment is associated with headaches in patients with multiple sclerosis (MS). Headaches can affect quality of life and overall function of patients with MS. We examined the frequency, relationships, patterns, and characteristics of headaches in response to IFN-ß in patients with relapsing-remitting multiple sclerosis (RRMS). Patients and Methods: This study was a prospective, longitudinal analysis with 1-year follow-up. The study comprised 796 patients with RRMS treated with IFN-ß (mean age 30.84±8.98 years) at 5 tertiary referral center outpatient clinics in Egypt between January 2015 and December 2017. Headaches were diagnosed according to the International Classification of Headache Disorders ICHD-3 (beta version), and data were collected through an interviewer-administered Arabic-language-validated questionnaire with an addendum specifically designed to investigate the temporal relationship between commencement of interferon treatment, and headache onset and characteristics. Results: Two hundred seventy-six patients had pre-existing headaches, and 356 experienced de novo headaches. Of 122 patients who experienced headaches before IFN-ß treatment, 55 reported headaches that worsened following onset of IFN-ß treatment. In patients with post-IFN-ß headaches, 329 had headaches that persisted for >3 months, 51 had chronic headaches, and 278 had episodic headaches, and 216 of these patients required preventive therapies. Univariate analysis showed a >6- and an approximately 5-fold increased risk of headache among those treated with intramuscular (IM) INF-ß-1a (OR 6.51; 95% CI: 3.73-10.01; P-value <0.0001) and 44 µg of SC INF-ß-1a (OR 5.44; 95% CI: 3.15-9.37; P-value <0.0001), respectively, compared with that in patients who received 22 µg of SC INF-ß-1a. Conclusion: Interferon-ß therapy aggravated pre-existing headaches and caused primary headaches in patients with MS. Headache risk was greater following treatment with IM INF-ß-1a and 44 µg SC INF-ß-1a.

RESUMEN

BACKGROUND: Despite multiple diagnostic tests, multiple sclerosis (MS) remains a clinical diagnosis with supportive paraclinical evidence. OBJECTIVE: To measure glutamate and nitric oxide serum levels in MS patients during and in between relapses to assess their potential role as biomarkers of disease activity and relapses. SUBJECTS AND METHODS: This cross sectional study was carried out on 70 MS patients and 40 age and sex matched apparently healthy controls. MS patients were divided into 2 groups; group 1 that included thirty MS patients without history of relapse within the last 3 months prior to recruitment and group 2 that included forty MS patients with history of relapse within the last 30 day prior to recruitment. RESULTS: Serum glutamate was significantly higher in group 2 (24.67 ±â€¯9.58 µg/ml) compared to group 1(12.5 ±â€¯4.9 µg/ml) (P value < 0.0001) and apparently healthy controls (3.5 ±â€¯1.3 µg/ml) (P value < 0.0001). Serum nitric oxide was significantly higher in group 2 (84.87 ±â€¯29.6 nmol/µl) than group 1 (41.99 ±â€¯24.2 nmol/µl) (P value < 0.0001) and apparently healthy controls (12.03 ±â€¯3.59 nmol/µl) (P value < 0.0001). Cutoff values of 17.5 µg/ml for glutamate and 75.2 nmol/µl for nitric oxide were found to predict occurrence of a relapse (sensitivity = 70% and 72.5% and specificity= 90% and 93.3% respectively). CONCLUSION: Serum glutamate and nitric oxide can be potential easily-accessible biomarkers of disease activity and relapses in MS patients.

RESUMEN

BACKGROUND: Multiple sclerosis (MS) is a complex autoimmune disease with a heterogeneous presentation and diverse disease course. Recent studies indicate a rising prevalence of MS in the Middle East. OBJECTIVE: To characterize the demographics and disease features of Egyptian patients attending four tertiary referral MS centers in Cairo. MATERIALS AND METHODS: This was a retrospective, observational study on 1,581 patients between 2001 and 2015. Medical records were reviewed and data were identified and extracted in a standardized electronic registry. RESULTS: The mean age of disease onset was 26.6±7.8 years, with the majority being female (2.11:1). Relapsing-remitting MS was the most common type (75.1%). The main presenting symptom was motor weakness (43.9%), which was also the most frequent symptom during the disease course. Family history of MS was found in 2.28%. Higher initial Expanded Disability Status Scale score, black holes, and infratentorial lesions on initial magnetic resonance imaging were independent factors for disease progression by univariate analysis (OR 3.87 [95% CI 1.84-6.51], 4.14 [95% CI 3.08-5.58], 4.07 [95% CI 3.21-4.99], respectively); however, in multivariate analysis, only infratentorial lesions were an independent risk for disease progression (OR 6, 95% CI 2.99-12.02; P=0.0005). CONCLUSION: The results from this registry - the largest for MS in the Arab region to date - are comparable to other registries with slight differences.
