Filter by:A group of 24 healthy volunteers are challenged one or three times with 20 male Schistosoma mansoni cercariae to investigate whether this leads to protection and to identify potential correlates of protection
Groups of 3 or 7 volunteers will be exposed to a predetermined number of female Schistosoma mansoni cercariae until 10 volunteers are found infected.
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 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.
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.
Mycobacterium tuberculosis (M. tb) is a pathogen with worldwide distribution which infects humans causing tuberculosis (TB), a transmissible disease resulting in very high mortality and morbidity; development of an effective vaccine is a global health priority. Over a billion people worldwide are infected with one or more helminths. Helminths are parasitic worms, of which Schistosoma mansoni is one species. There is some evidence that helminth infection may affect a person's response to a vaccine. In this trial the investigators hope to investigate whether Schistosoma mansoni infection affects adolescents' responses to a candidate TB vaccine called MVA85A, as adolescents are a crucial target group for an effective TB vaccine.
Upper gastrointestinal bleeding (UGIB) is a major cause of morbidity and mortality in patients with portal hypertension secondary to schistosomiasis mansoni. Taking into account the endemic nature of schistosomiasis mansoni in our region and the high morbidity and mortality directly associated with rupture of esophageal varices and UGIB in affected patients, we conducted a prospective randomized trial in patients with schistosomiasis and a history of bleeding esophageal varices. Its purpose was to assess the efficacy of endoscopic treatment alone compared with the efficacy of sclerotherapy preceded by a surgical treatment: Esophagogastric devascularization with splenectomy (EGDS).
This study is about intestinal schistosomiasis, commonly known as bilharzia, in children aged 1-5 years along Lake Victoria shoreline.The children will be screened for S. mansoni and the effects of the disease will be assessed.Children found positive with S. mansoni will be treated with praziquantel and followed up for a year.
Clinical Trial Phase:Phase III Primary Objectives: - Compare Mirazid and Praziquantel cure rates for both Schistosoma species. - Compare Mirazid and Praziquantel effect in lowering the intensity of infection for both Schistosoma species. Secondary Objective:Identify and compare the types and severity of side and adverse effects between the Mirazid and Praziquantel. Study Population:200 Schistosomiasis infected persons of both types of Schistosomiasis aged from 15-35 years. Those subjects will be selected from among those screened.Subjects will include both genders excluding chronically ill such as chronic liver disease patients and those with both types of Schistosomiasis. Recruitment Period:3 months and subjects follow up for another 3 months followed by 3 months for statistical analysis and report writing Study Duration: Total study duration is expected to be 9 months: 3 months for recruitment, 3 months for follow up and 3 months for data management and report writing. Endpoints: Will be measured at 3 months of successful administration of treatment either Mirazid or Praziquantel as per the randomization scheme. By then, final assessment of the response to treatment will be done by examining urine or stool of the subject for presence of Schistosoma eggs and its density if found. Three negative urine or stool samples collected 2-days apart at 12 weeks post treatment will indicate treatment success. One positive sample collected at week 12 will indicate infection with Schistosomiasis.
The purpose of this study is to evaluate the use of a urine test strip in diagnose schistosoma mansoni in areas of Kenya where the rate of infections are low. The hypothesis is that the urine strip test is a superior tool to the conventional parasitological tools used to diagnose schistosomiasis mansoni infections in area where there is low transmission
