Abstract
Cysticercosis is one of the main causes of secondary epilepsy in sub-Saharan Africa. To estimate the seroprevalence of cysticercosis among epileptic patients, we conducted a cross-sectional study of patients attending neurology consultation in Abidjan, Côte d'Ivoire. Methods: Patients' socio-demographic and lifestyle data were collected as well as blood samples for serological testing using ELISA and Western blot based on IgG antibodies detection. For qualitative variables comparison, Chi(2) or Fisher tests were used; a Student's t-test was used to compare quantitative variables. A multivariate logistic regression model was fit to identify risks factors. Results: Among 403 epileptic patients included in the study, 55.3% were male; the median age was 16.9 years; 77% lived in Abidjan; 26.5% were workers. Most patients included in the study had tonic-clonic seizures (80%), and 11.2% had focal deficit signs. The seroprevalence of cysticercosis was 6.0%. The risk was higher in patients over 30 years old (aOR = 5.1 (1.3-20.0)) than in patients under 16. The risk was also considerably high in patients who reported epileptics in the family (aOR = 5 (1.7-14.6)). The risk was three-fold less in females than in males. Conclusions: This study highlighted the exposure of epileptic patients to Taenia solium larvae in an urban area. The risk of positive serology was increased with age, male gender, and family history of epilepsy.
