Egyptian adaptation and validation of the Edinburgh Cognitive and Behavioral Amyotrophic Lateral Sclerosis Screen (ECAS-EG).

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is the most common, fatal adult neuromuscular disease. It is a multi-system disorder characterized primarily by motor manifestations, but there is established evidence for cognitive and behavioral impairment, which is associated with poor prognosis, hence, the importance of tools for its assessment. The Edinburgh Cognitive and Behavioral Assessment Screen (ECAS) is an invaluable assessment tool for cognition in ALS-front temporal spectrum dementia (FTSD), as it accommodates physical challenges that usually confound traditional neuropsychological testing in those patients. OBJECTIVE AND METHODS: To validate the Egyptian Arabic version of ECAS (ECAS-EG) based on the original English scale. This is a prospective study. The ECAS was adapted and administered to 62 Egyptian ALS patients and 60 healthy controls. Patients were recruited from the Neuromuscular Unit, Ain Shams University Hospital. The ECAS was adapted to Egyptian Arabic after being translated using the back translation method. Internal consistency of the test, inter-rater reliability, and construct validity were assessed. RESULTS: The Egyptian Arabic version of ECAS (ECAS-EG) showed good internal consistency using Cronbach's alpha of 0.84. Inter-rater reliability was tested, values for all variables were compared, and no statistically significant differences were found (ICC = .997). ECAS-EG discriminated significantly between the patients from the control subjects (p-value of 0.001). There was a strong positive correlation between the ECAS-EG total score and the MoCA total score with a p-value of 0.001, thus indicating convergent validity. The test showed that 63% of Egyptian ALS patients were cognitively affected; most affected domains were executive functions and verbal fluency. CONCLUSION: The current study proves that the Egyptian version of the ECAS (ECAS-EG) is valid and reliable among Egyptian ALS patients and it would be applicable to the general Arabic-speaking population.

Telephone-based assessment of multiple sclerosis patients at Ain Shams University Hospital in the coronavirus disease 2019 pandemic.

BACKGROUND: Assessment of multiple sclerosis (MS) patients during the era of the coronavirus disease 2019 (COVID-19) pandemic was confronted with the overwhelmed healthcare facilities in Egypt and fear of the patients to get infected while attending the follow-up visits. This study aimed to assess the value of telephone-based assessments in the follow-up of MS patients. It includes one hundred and five patients who participated in the study and completed 3 telephone-based assessments which are the Hauser Ambulation index, Multiple Sclerosis Neuropsychology Questionnaire (MSNQ), and Symptoms of Multiple Sclerosis Scale (SMSS). RESULTS: The Hauser Ambulation index was significantly correlated with the latest Expanded Disability Status Scale (EDSS) score done within 1 month from the telephone call (r=0.738, P<0.001). The analysis of MSNQ scores showed that one-third of the study population had evidence of cognitive and/or neuropsychological impairment. Post hoc analysis regarding the cognitive and psychological impairment component of SMSS revealed that the patients who answered "Never" had significantly lower MSNQ scores compared to those who answered "Sometimes" (P=0.016), "Often" (P=0.022), and "Always" (P=0.001). The comparison of the EDSS scores of the patients regarding the sensory-motor impairment component of SMSS showed a non-significant difference. CONCLUSION: The Hauser Ambulation index may be a reliable telephone-based tool for the assessment of physical disability. The MSNQ and the cognitive and psychological impairment component of SMSS can be used for the assessment of cognitive and psychological impairment among patients with MS.

Magnetic resonance imaging markers of disability in Egyptian multiple sclerosis patients.

BACKGROUND: The aim of this work was to identify the magnetic resonance imaging (MRI) markers of disability in Egyptian multiple sclerosis (MS) patients. SUBJECTS AND METHODS: This retrospective observational study included 673 patients recruited from the registry of the MS unit at Ain Shams University hospitals. At the time when the MRI scans of the brain and spinal cord were done (with and without gadolinium enhancement), clinical disability was rated using the Expanded Disability Status Scale (EDSS) during the patient's first visit. RESULTS: Females represented 72.5%, all types of MS were included, the mean age of onset was 26.1 ±â€¯7.7(SD) years, mean duration of illness was 8.3 ±â€¯5.5(SD) years. The mean EDSS of the patients was 3.5 ±â€¯2.1. The study population was divided into three groups according to the EDSS score; mild from 0-3 (56.6%), moderate from 3.5-6 (34.9%) and severe more than 6 (8.5%). The number and types of MRI lesions (T2, T1 black holes, T1 contrast and confluent lesions) in the different anatomical locations (periventricular, juxtacortical, infratentorial and spinal) were correlated with the clinical and demographic data of the patients as well as with the EDSS score. The presence of confluent brain lesions (P Ë‚ 0.001), brain T1 hypointense lesions (P = 0.009), and infratentorial T2 lesions (from 1 to 3 lesions (P = 0.04), from 4 to 10 (P ˂ 0.001) and more than 10 (P ˂ 0.001)), were significantly correlated to high EDSS scores after linear regression analysis. CONCLUSION: This is the first Egyptian study to show that infratentorial lesions, confluent brain lesions and T1 hypointense lesions are conventional MRI parameters that correlate with the degree of disability in Egyptian MS patients.

Clinical characteristics of patients with multiple sclerosis enrolled in a new registry in Egypt.

BACKGROUND: Epidemiological studies of multiple sclerosis (MS) are lacking in Egypt. OBJECTIVE: To study the characteristics of Egyptian patients with multiple sclerosis in a new registry in a major tertiary referral centre in Cairo, Egypt. SUBJECT AND METHODS: Patients were from the project MS database of the Multiple Sclerosis Unit at Ain Shams University Hospitals (N=950). We conducted a detailed medical history and examination including the Expanded Disability Status Scale (EDSS). RESULTS: Females represented 72% of subjects (female: male ratio 2.57:1). The mean age of disease onset was 26.1±7.6 years. Relapsing-remitting MS (RRMS) was the most common presentation (74.6%). Visual or sensory symptoms were the most common at presentation with RRMS, while motor symptoms were the most common presentation in other types of MS. Time to diagnosis was delayed up to 2 years in 27.8% of patients. The mean EDSS score was 3.6±2.1; 55% had EDSS≤3. About half (49%) received a disease-modifying drug. Progressive MS and motor presentation were associated with higher disability. CONCLUSIONS: This is the first documented MS registry from Egypt. The clinical characteristics of MS in Egypt was similar to other Arab countries and western countries. MS is more common among females in Egypt, with RRMS being the most common presentation. Visual symptoms and motor symptoms were the most common presentations in RRMS and progressive MS, respectively. Our findings also highlight the value of establishing registries in Egypt in order to be able to study, prospectively, the clinical course of the disease, the response to various DMD's and the epidemiology of MS in Egypt.
