“…In fact, other studies performed in Mozambique, Burkina Faso and Tanzania also found that seropositivity to cysticercal antigens was associated with severe headache [14,15,42,43]. Nevertheless, in other settings such as in Anzoa ´tegui in Venezuela, Vietnam and Nabo Village in Tiandong, China, no statistical association was found between these two variables [44][45][46]. Our findings may reflect the fact that headache may be correlated to the pathogenesis of the disease in this study setting.…”

“…To the contrary, in Tanzania [43], females were more likely to be seropositive, while in Burkina Faso and Vietnam this was true for males [29,58]. On the other hand, neither gender nor age presented a statistically significant association with seropositivity to cysticercosis in other studies [30,44,46,60].…”

“…Furthermore, although there is a fraction of Muslim people amongst our study participants, we did not expect our findings to be affected by the religion, since cysticercosis is acquired mainly through water or food contaminated with T. solium eggs, and consequently anyone can acquire the infection regardless of the consumption of pork meat or professed religion. In some studies, food, water and hygiene related factors were significantly associated with cysticercosis seropositivity, including consumption of undercooked pork [44], and using the same water source [43]; although in other studies, factors such as consumption of raw meat and/or vegetables [30] and hygiene (presence of latrine) [57] were not associated with cysticercosis seropositivity.…”

Background Taenia solium (neuro-)cysticercosis is a neglected tropical disease often associated with epileptic seizures and reportedly with other neuropsychiatric (= neurological and psychiatric) disorders. This study aimed to evaluate the association of the disease with selected neuropsychiatric disorders and/or symptoms (chronic headache, epileptic seizures/epilepsy and psychosis) in Mocuba district, Mozambique. Methodology Between March and May 2018, a cross-sectional study was conducted among 1,086 participants aged 2 years or above in Mocuba district, Zambézia province, central Mozambique to assess the seroprevalence of human cysticercosis and risk factors for infection, as well as to explore its relation to selected neuropsychiatric disorders. Socio-demographic and clinical data were collected from each participant using a modified questionnaire designed by the Cysticercosis Working Group for Eastern and Southern Africa. Additionally, neuropsychiatric disorders, such as chronic headache, epileptic seizures/epilepsy and psychosis were assessed using four vignettes. T. solium antigen and cysticercosis IgG in serum were detected using both T. solium antigen B158/B60 enzyme linked immunosorbent assay (ELISA) and LDBIO Cysticercosis Western Blot, respectively. Principal findings Overall, 112/1,086 participants (10.3%) were sero-positive for T. solium antigen or antibodies. Prevalence of antibodies (6.6%; n = 72) was higher than of antigens (4.9%; n = 54). In the questionnaires, 530 (49.5%) of participants reported chronic headache, 293 (27%) had generalized epileptic seizures, 188 (18%) focal seizures and 183 (18.3%) psychosis. We found a statistically significant association between seropositivity for T. solium and chronic headache (p = 0.013). Additionally, increasing age (p = 0.03) was associated with Ag-ELISA seropositivity. Conclusions Our study revealed that in Mocuba, T. solium cysticercosis is prevalent and associated with self-reported chronic headache. Additionally, in the study setting, the seroprevalence of cysticercosis increased with age. However, it is not associated with other neuropsychiatric disorders such epileptic seizures/epilepsy and psychosis. Future studies are needed to confirm the burden of neuropsychiatric disorders and their possible etiology, including neurocysticercosis, with additional serological, molecular biological and radiological diagnostic tools, as well as in-depth clinical examinations.

“…encontraron una edad promedio de 37 años en México (12), en ambos casos población en edad laboral y en plena edad productiva. Entre los pacientes evaluados la mayor parte provenían del área rural con predominio de afiliación al régimen Fuente: elaboración propia subsidiado, lo que corresponde con un bajo estrato socioeconómico, lo cual es compatible con los factores de riesgo conocidos para la enfermedad (13,14). El ligero predominio femenino en nuestra muestra es consistente con otros estudios locales y regionales (15).…”

INTRODUCCIÓN: La neurocisticercosis es una infección del sistema nervioso central causada por el estadio larvario del cestodo Taenia solium, y se estima que puede ocasionar hasta 30% de los casos de epilepsia en los países donde esta parasitosis es endémica. El objetivo de este estudio fue determinar la frecuencia de pacientes que presentaron epilepsia como secuela de neurocisticercosis en un hospital universitario en Popayán. MATERIALES Y MÉTODOS: Se realizó un estudio retrospectivo con todos los pacientes con diagnóstico de neurocisticercosis que ingresaron al Hospital Universitario San José entre enero 2014 y diciembre 2018 que cumplieron los criterios de inclusión. RESULTADOS: Se encontraron 50 pacientes, de estos, 40 (80%) reingresaron, encontrándose que 37 (74%) presentaron epilepsia como secuela. Las edades más afectadas fueron la de 41 a 60 años; 48 (96%) provenían del departamento del Cauca en especial de Mercaderes, y 33 (66%) de área rural. El síndrome convulsivo fue la manifestación clínica de ingreso más frecuente. La TAC fue la técnica de imagen de elección. CONCLUSIÓN: El departamento del Cauca se considera como una de las áreas endémicas para neurocisticercosis en Colombia, y la epilepsia secundaria es un secuela común.

“…Cysticercosis is frequent in rural areas since it is associated with breeding of pigs under poor sanitary and environmental conditions, and low educational and socioeconomic level (Villalobos et al, 2007;Toquero, Morocoima & Ferrer, 2017;Maya et al, 2003). These conditions are all evidenced in María La Baja -Bolívar, since the highest educational level achieved by the majority of pig breeders (62%) was up to primary level, and their access to healthcare services was through subsidized regime.…”

Cysticercosis is a parasitic infection caused by the larvae of the pork tapeworm, Taenia solium. It is acquired through fecal-oral contamination, and it can affect humans and pigs. In Colombia, this is an endemic infection especially in locations where breeding and commercialization of pigs are performed under poorly hygienic conditions, such as in Maria La Baja, Department of Bolívar. However, seroprevalence of anti-cysticercus antibodies in pigs or pig breeders at these locations has not been determined. Thus, using indirect immunoassays we quantified anti-cysticercus antibodies in serum samples of pigs (n=254) and pig breeders (n=121) in Maria La Baja. Furthermore, a questionnaire was applied in order to determine environmental, cultural, and socioeconomic variables. Anti-cysticercus antibodies were detected in 36.6% (93/254) of pigs and 44.6% (54/121) of pig breeders. A significant causal association was identified for daily cleaning of pigsties and having anti-cysticercus antibodies with an aOR = 15.16 (CI 95%: 2.13 - 107.86; p = 0.0002). No significant associations were identified between the evaluated variables and seroprevalence of anti-cysticercus antibodies in pigs. Our study indicates that there is a high seroprevalence of anti-cysticercus antibodies in humans and pigs in locations where handling of pigs is performed under poor hygienic conditions. Our results suggest that there is a need to design and implement prevention and control strategies in Maria La Baja in order to reduce transmission of this disease.
