Filter by:Prospective cross-sectional study at the outpatient clinic (OPC) of the Bagamoyo District Hospital (BDH) in Tanzania. Assessment of basic epidemiological data (Point prevalence and risk factors) on CKD with simple clinical, laboratory tests and the patients history. After informed consent blood samples are taken for complete blood count, serum creatinine, HbA1c, HIV-Screening, and urine samples for dipstick, urine sediment, and albumin-creatinine ratio. Further, office blood pressure, weight and height are taken. Further, patients history are asked by a questionnaire (i.e.history of infectious and cardiovascular diseases and basic demographic data: i.e. sex, age). CKD is defined as the presence of either impaired kidney function and/or albuminuria based on a one-time measurement. Primary outcome of the study are prevalence rates of CKD and the impact of non-communicable and communicable disorders on CKD.
The study will be conducted as a randomized, controlled, double blind Phase 1b dose-escalating clinical trial in up to 60 healthy adult males and non-pregnant females living in the S. mansoni-endemic area of Americaninhas, Brazil. The primary objective of this trial is to assess the safety and reactogenicity of ascending doses of Sm-TSP-2/Alhydrogel(R) (10mcg, 30mcg, or 100mcg) vaccine with or without AP 10-701 given as three doses administered on Days 1, 57, and 113.
The clinical trial phase 2a is designed to assess the safety of the active ingredient (protein + adjuvant) and secondarily its immunogenicity in healthy male adults from 18 to 49 years of age with a history of infection with intestinal and urinary schistosomiasis, living in the Valley of the Senegal River, a highly endemic area for schistosomiasis. Two arms in the study will test different doses of GLA-SE adjuvant (2.5 and 5 μg). This phase IIA in adults is considered to be a preliminary step in safety before starting trials in children in endemic areas to S. mansoni or S. haematobium, target population of the vaccine.
The aim of this study is to assess the impact of Schistosoma mansoni infection and its treatment on genital immunology and HIV susceptibility in Ugandan women.
An open label, randomized controlled trial of single vs. multiple treatments of praziquantel in intestinal African schistosomiasis in Côte d'Ivoire This study aims to determine the efficacy of repeated (up to four times) praziquantel treatment against S. mansoni infection in school-age children from Côte d'Ivoire using the traditional Kato-Katz thick smear technique, but also with more accurate and non-invasive antigen- and DNA-detection methods.
The Phase II study consisted of two parts, part 1 is open label, randomized, controlled and exploratory dose finding in children aged between 2 and 6 years infected with S. mansoni. Part 2 investigated efficacy and safety with the selected formulation and dosage in S. mansoni infected children aged between 3 months - 2 years.
Groups of 3 or 7 volunteers will be exposed to a predetermined number of male Schistosoma mansoni cercariae until 10 volunteers are found infected.
Objective and Hypotheses: This project has the overall objective of implementing and evaluating new approaches to reducing the current and future burden of urinary schistosomiasis in young children using the antihelminthic drug Praziquantel. The project aims to (1) determine the operational health benefits of treating schistosome infections early on re-infection and morbidity reduction, (2) determine if gut or urine microbiome structure (species diversity or abundance) is a risk factor for S. haematobium infection or morbidity, and (3) elucidate the factors and underlying mechanisms mediating the reduction/reversal of schistosome-related morbidity and resistance against infection/re-infection in young children.
This is a Phase I, first-in-human study of a vaccine against S. mansoni infection.The study will recruit 72 healthy adult males and non-pregnant females from a single clinical center to test two formulations of Sm-TSP-2 vaccine (using the Alhydrogel® only, and using Alhydrogel® plus GLA-AF), each at 3 different doses: 10ug, 30ug, and 100ug. The primary objective is to assess the safety and reactogenicity of ascending doses of Sm-TSP-2/Alhydrogel® (10ug, 30ug, or 100ug) with or without GLA-AF vaccine given as three doses administered on Days 1, 57, and 113.
Schistosomiasis is increasingly encountered among travellers returning from the tropics and is known for its focal endemicity, associated with the presence of the snail intermediate host in fresh water. Because schistosomiasis in travellers is often atypical or asymptomatic due to the low intensity of infection, many infections likely go undiagnosed and will develop into chronic schistosomiasis. Conventional treatment of schistosomiasis in travellers with praziquantel 40mg/kg daily dose is known for its modest success rate. Diagnosis of schistosomiasis relies on egg detection, which has a poor sensitivity in low burden infections, or serology, which is inadequate to monitor cure. The department of parasitology of the Leiden University Medical Center has developed a novel diagnostic test based on the up-converting phosphor technology (UCP) to detect circulating anodic antigen (CAA). This test can be performed on serum and urine to detect low intensity schistosomiasis infections and confirm cure after praziquantel treatment. This study will assess the performance of UCP-CAA in travellers with high-risk water contact.
