Profil epidemiologique de l’epilepsie chez des patients atteints de troubles du spectre de l’autisme: Etude de 45 cas a Dakar (Senegal)

Description: Troubles du spectre de l’autisme (TSA) et épilepsie peuvent coexister chez une même personne constituant des facteurs de mauvais pronostic bilatéraux. Objectif:  Décrire les éléments sociodémographiques de patients atteints de TSA et étudier les aspects clinico-paracliniques et évolutifs des épilepsies chez ces patients. Patients et Méthodes:  Etude transversale et descriptive au service pédopsychiatrique du CHNU Fann, avec analyse des dossiers, via un questionnaire standardisé, de tous les patients suivis entre Janvier 2004 et Septembre 2018 pour TSA avec ou sans épilepsie. Résultats:  Quarante-cinq patients avec TSA colligés, avec une fréquence de l’épilepsie de 37,8%. L’épilepsie avait débuté avant l’âge de 5 ans dans 94% des cas. Les crises étaient généralisées (58,8%), essentiellement motrices tonico-cloniques (80%), ou focales (35,3%), avec une fréquence de 2 crises/jour à 1 crise/semaine. L’EEG de veille et sommeil montrait des anomalies majoritairement frontales dans 60%, et centro-pariétales dans 26,6% des cas. L’imagerie cérébrale était normale dans 93,9% des cas, et les potentiels évoqués auditifs (PEA) normaux dans 87,2% des cas. La prise en charge était multidisciplinaire pour les TSA (neuropsychologique, psychomotrice, orthophonique) et médicale, essentiellement (82,4%) en monothérapie pour l’épilepsie. Les médicaments antiépileptiques utilisés étaient le valproate de sodium (58,8%) et le phénobarbital (17,6). Le niveau d’instruction était bas avec 40% de non-scolarisés et 55,6% au primaire. Seuls 6,7% étaient autonomes et 20 patients nécessitaient une aide quasi-constante. Conclusion: La prévalence de l’épilepsie chez les patients atteints de TSA varie suivant les études. Une prise en charge globale et multidisciplinaire de l’épilepsie et des TSA améliore les troubles de comportement.   English Title: Epidemiologic profile of epilepsy in patients with autism spectrum disorders: study of 45 cases in Dakar (Senegal) Description: Autism spectrum disorders (ASD) and epilepsy can coexist in the same person, which are factors of bilateral poor prognosis. Purpose: To describe the socio-demographic profile of ASD patients and to study the clinical, paraclinical and evolutive aspects of epilepsy among them. Patients and methods: We did a cross-sectional and descriptive study in the department of child psychiatry of Fann university hospital in Dakar. We analyzed patients’ files followed between January 2004 and September 2018 for autism’s spectrum disorders with or without epilepsy. We used a standardized survey with several items. Results: Forty-five patients with ASD were collected, with an epileptic frequency of 37.8%. Epilepsy had started before the age of 5 years in 94% of cases. Seizures were generalized (58.8%), mainly tonico-clonic (80%), or focal (35.3%), with a frequency of 2 seizures per day to 1 seizure per week. The awake and sleep EEG showed abnormalities mostly in frontal area in 60%, and centro-parietal in 26.6%. Brain imaging was normal in 93.9%, and auditory evoked potential (AEP) normal in 87.2%. Management was multidisciplinary for ASD (neuropsychological, psychomotor, speech therapy) and medical, mainly (82.4%) monotherapy for epilepsy. The main molecules were: sodium valproate (58.8%) and phenobarbital (17.6). The level of education was low with 40% of students out of school and 55.6% in primary school. Only 6.7% were self-reliant and 20 patients needed almost constant assistance. Conclusion: The prevalence of epilepsy in patients with ASD varies according to the studies. The global and multidisciplinary management of epilepsy and ASD improves behavioral disorders

Acceptability and Utilization of Three Nutritional Supplements during Pregnancy: Findings from a Longitudinal, Mixed-Methods Study in Niger

Nutritional status in pregnancy is a key determinant of birth outcomes. In low-income countries, maternal diets are often limited, and daily nutrient supplements are recommended to fill nutrient gaps. As a result, it is important to understand the factors influencing acceptability and utilization of nutrient supplements in these settings. Qualitative data (individual interviews and focus group discussions with pregnant women, household members, and study staff) and quantitative data (unannounced household spot checks) were collected in 24 villages in the Maradi region of south-central Niger. Each village was randomly assigned to one of three study arms, with pregnant women receiving either iron and folic acid (IFA) supplements, multiple micronutrient (MMN) supplements, or medium-quantity lipid-based nutrient supplements (MQ-LNS) for daily consumption during pregnancy. Data were collected longitudinally to capture changes in perspective as women progressed through their pregnancy. Participants accepted all three supplement types, and perceived a wide range of health benefits attributed to supplement consumption. However, several important barriers to appropriate consumption were reported, and rumors about the supplements leading to childbirth complications also decreased utilization. The household spot checks suggested that IFA had the highest level of correct consumption. Overall, despite a stated high level of acceptance and enthusiasm for the supplements among participants and their household members, certain fears, side effects, and organoleptic factors led to decreased utilization. The effectiveness of future programs to improve maternal nutritional status through supplementation may be improved by understanding perceived barriers and facilitating factors among participants and tailoring communication efforts appropriately

Surveillance of Viral Encephalitis in the Context of COVID-19: A One-Year Observational Study among Hospitalized Patients in Dakar, Senegal

The burden of encephalitis and its associated viral etiology is poorly described in Africa. Moreover, neurological manifestations of COVID-19 are increasingly reported in many countries, but less so in Africa. Our prospective study aimed to characterize the main viral etiologies of patients hospitalized for encephalitis in two hospitals in Dakar. From January to December 2021, all adult patients that met the inclusion criteria for clinical infectious encephalitis were enrolled. Cerebrospinal fluids, blood, and nasopharyngeal swabs were taken and tested for 27 viruses. During the study period, 122 patients were enrolled. Viral etiology was confirmed or probable in 27 patients (22.1%), with SARS-CoV-2 (n = 8), HSV-1 (n = 7), HHV-7 (n = 5), and EBV (n = 4) being the most detected viruses. Age groups 40–49 was more likely to be positive for at least one virus with an odds ratio of 7.7. The mortality was high among infected patients, with 11 (41%) deaths notified during hospitalization. Interestingly, SARS-CoV-2 was the most prevalent virus in hospitalized patients presenting with encephalitis. Our results reveal the crucial need to establish a country-wide surveillance of encephalitis in Senegal to estimate the burden of this disease in our population and implement strategies to improve care and reduce mortality
