Abstract

Background: This study aimed at describing the epidemiology of (neuro)cysticercosis as well as its clinical and radiological characteristics in a Taenia solium endemic district of Zambia. Methods: This was part of a cross-sectional community-based study conducted in Sinda district to evaluate an antibody-detecting T. solium point-of-care (TS POC) test for taeniosis and (neuro)cysticercosis. All TS POC cysticercosis positive (CC+) participants and a subset of the TS POC cysticercosis negative (CC-) received a clinical evaluation and cerebral computed tomography (CT) examination for neurocysticercosis (NCC) diagnosis and staging. Results: Of the 1249 participants with a valid TS POC test result, 177 (14%) were TS POC CC+. Cysticercosis sero-prevalence was estimated to be 20.1% (95% confidence intervals [CI] 14.6–27.0%). In total, 233 participants received a CT examination (151 TS POC CC+, 82 TS POC CC-). Typical NCC lesions were present in 35/151 (23%) TS POC CC+, and in 10/82 (12%) TS POC CC- participants. NCC prevalence was 13.5% (95% CI 8.4–21.1%) in the study population and 38.0% (95% CI 5.2–87.4%) among people reporting epileptic seizures. Participants with NCC were more likely to experience epileptic seizures (OR = 3.98, 95% CI 1.34–11.78, p = 0.01) than those without NCC, although only 7/45 (16%) people with NCC ever experienced epileptic seizures. The number of lesions did not differ by TS POC CC status (median: 3 [IQR 1–6] versus 2.5 [IQR 1–5.3], p = 0.64). Eight (23%) of the 35 TS POC CC+ participants with NCC had active stage lesions; in contrast none of the TS POC CC- participants was diagnosed with active NCC. Conclusion: NCC is common in communities in the Eastern province of Zambia, but a large proportion of people remain asymptomatic.
