The road towards sustainable control of schistosomiasis in the Democratic Republic of Congo: Pre-assessment of staff performance and material resources in endemic regions

Objective:To improve knowledge and practice of health staff as well as the availability of material resources for diagnosis and management of schistosomiasis in two endemic provinces of DRC (Kinshasa and Bas-Congo).Methods:Structured interviews were performed using questionnaires with staff from 35 healthcare facilities in 9 health zones (HZ) of Kinshasa and 2 HZ in Bas-Congo.Results:Schistosomiasis was reported to be present in all the included HZ.Health staff knew the most important symptoms of schistosomiasis,but advanced symptoms were more accurately reported in Bas-Congo.Knowledge of symptoms related to schistosomiasis such as anemia (P =0.0115) and pollakiuria (P =0.0260) was statistically different in both two provinces.Kato-Katz technique and urine filtration were unavailable in both provinces.Parasitological diagnosis was mostly performed using the direct smear method.PZQ was available in 70％ of the health facilities,all situated in Bas-Congo.Diagnosis and treatment mostly relied on symptoms and cost more in urban area than in rural.Conclusions:Though knowledge on schistosomiasis among health staff appears sufficient,substantial efforts still must be made to improve the availability of diagnostic tools and treatment in the health facilities in DRC.

Parasitosis intestinales en pacientes con epilepsia de origen desconocido / Intestinal parasitosis found in patients with epilepsy of unknown etiology

Introducción: la epilepsia es una alteración del sistema nervioso central que afecta a un estimado de 50 millones de personas en el mundo, de los cuales 85 porciento vive en países en desarrollo. Alrededor de 20 porciento de las epilepsias son de difícil control o refractarias. En Cuba no existen antecedentes de estudios acerca del comportamiento de las parasitosis intestinales en estos pacientes, por lo cual se decidió realizar la presente investigación en un grupo de pacientes con epilepsia de origen desconocido del Instituto de Neurología y Neurocirugía de La Habana. Objetivos: determinar la prevalencia y las manifestaciones clínicas de las parasitosis intestinales, y relacionar estas infecciones con la existencia de epilepsia refractaria a los fármacos antiepilépticos. Métodos: se aplicó un cuestionario y se recogió una muestra de heces por cada paciente, se realizaron técnicas de diagnóstico coproparasitológico, como son el examen directo, el método de concentración de Willis y el procedimiento cuantitativo de Kato Katz

Introduction: the epilepsy is an alteration of the central nervous system (CNS) which roughly affects 50 millions of persons worldwide; almost 85 percent of them live in developing countries. Approximately 20 percent of epilepsies are difficult to control or they are called refractory epilepsies. Taking into account the lack of Cuban reports about the behavior of intestinal parasitic infections in these patients, it was decided to carry out this research study in a group of epileptic patients with unknown etiology, from the Institute of Neurology and Neurosurgery in Havana. Objectives: to determine the prevalence and the clinical manifestations of intestinal parasitic infections, and the possible association of these infections with epilepsy refractory to the antiepileptic drugs. Methods: a questionnaire was applied and one fecal sample was taken per patient. Various parasitological techniques were implemented, including direct wet mount, Willis concentration technique, and Kato Katz quantitative procedure

Age-related worm load and worm fecundity patterns in human populations, as indicated by schistosome circulating antigens

Recently, our group determined the relationship between serum CAA levels and fecal egg counts in two foci very intense Schistosoma mansoni transmission: Maniema (Zaire), an area endemic for S. mansoni since several decades, and Ndombo (Senegal), where transmission has only been established since a few years. The objetive was to study and compare age-related worm load and worm fecundity patterns in these two different endemic settings. Here, we will summarize the most important findings and conclusions of this study.
