“…Inicialmente aplicada en el sur del Ecuador, la quimioterapia masiva con praziquantel mostró ser temporalmente eficaz en disminuir la prevalencia de teniasis y de cisticercosis porcina (21) . Subsecuentemente, esto se replicó en México, Guatemala, Perú y otros países, con similares resultados (22)(23)(24)(25) . La Figura 2.…”

por el Grupo de Trabajo en Cisticercosis en Perú RESUMEN La neurocisticercosis, infección del sistema nervioso humano por el estadio larvario de la Taenia solium, es una causa importante de epilepsia y otras manifestaciones neurológicas en el Perú y en la mayoría de países en desarrollo. Desde 1987, el Grupo de Trabajo en Cisticercosis en Perú ha desarrollado una serie de estudios epidemiológicos que han llevado a estimar el impacto y entender la transmisión de la Taenia solium, y que posteriormente se aplicaron al diseño y ejecución de un programa de control en Tumbes, en la costa norte del país. En este artículo se revisan los principales hallazgos epidemiológicos, así como las líneas generales del programa de eliminación y las herramientas utilizadas. Los avances en el control de la teniasis/cisticercosis en nuestro país abren el camino hacia su eliminación y eventual erradicación.Palabras clave: Cisticercosis; Taenia solium; Epidemiología; Control de enfermedades transmisibles; Perú (fuente: DeCS BIREME). EPIDEMIOLOGY AND CONTROL OF CYSTICERCOSIS IN PERU ABSTRACTNeurocysticercosis, the infection of the human central nervous system by the larval stage of the cestode Taenia solium, is an important cause of epilepsy and other neurological manifestations in Peru and most developing countries. Since 1987, the Cysticercosis Working Group in Peru has performed a series of epidemiological studies which led to estimate the impact and to better understand the transmission of Taenia solium. This information was later applied to the design and execution of a control program in Tumbes, in the Northern Coast of Peru. This paper reviews the main epidemiological findings, as well as the conceptual framework of the elimination program and the tools used. Advances in the control of taeniasis/cysticercosis in our country open the road towards its elimination and potential eradication.

“…Seropositivity using ELISA was 11% before treatment and 7% afterwards, in the 30-39 year age group, antibody detection decreased from 30% to 7% suggesting that elimination of tapeworms reduces the possibility of contact with infective eggs. Interestingly, in the geographic section of the community where 3 of the 4 tapeworm carriers were found and treated, seropositivity was reduced from 19% to 2%, indicating that serum antibodies to Taenia antigens are short-lived and diminish, as contact with the parasite is lost [34]. In the second study performed in Atotonilco (3007 inhabitants), 87% of the community received a s i n g l e d o s e o f 5 m g / k g f o l l o w i n g a recommendation from WHO [60].…”

“…Many epidemiological surveys were performed with ELISA in the 1980´s, supported by direct detection of cysticerci in pigs' tongue and tapeworm eggs in human feces [27,28,[30][31][32][33][34] and, in the 1990's, by western blot (WB) [27,30,[35][36][37][38][39][40][41] using an enriched fraction of glycoproteins as antigen source [42] allowing the demonstration of the presence of all the components of the life cycle (Tables 2 and 3), [24]). When data from table 1 are compared to those of tables 2 and 3, it is evident that the prevalence of anti-cysticercus antibodies in humans (2.3-24%) is much higher than the finding of the parasite in pathology studies (0.02-5.9%), indicating that antibodies reflect exposure and not necessary the presence of the parasite; its serologic confirmation can be obtained by detecting cysticercal antigens.…”

“…Its importance became evident due to the high frequency of neurocysticercosis in neurological hospitals, where it is found in more than one of each 10 patients admitted and in one of each two late onset epilepsy cases diagnoses (Velasco-Suarez et al 1982, Vazquez & Sotelo 1992. The use of immunodiagnostic methods has shown that in rural as well as urban open population, anticysticercus antibodies can be found up to 15% (Diaz-Camacho et al 1991, Schantz et al 1994, Correa et al 1999, Garcia-Garcia et al 2000. This information has allowed recognizing human cysticercosis as a public health problem in countries of Latin America, Africa and Asia, where, in the last two decades, different control measures have been evaluated (Gemmell et al 1983, Flisser 1989.…”
