Filter by:Knowledge, acceptability and perception of paediatric schistosomiasis and its treatment will be explored through a social science-driven mixed-methods approach within three endemic countries: Kenya, Uganda and Côte d'Ivoire.
This is a Phase 1, open-label, dose-escalation clinical trial to evaluate the safety, reactogenicity, and immunogenicity of the Sm-p80+GLA-SE vaccine candidate in healthy adults between 18 and 55 years of age. Forty-five subjects will receive a series of three intramuscular injections 28 days apart with dose based on group. Five treatment groups, each including nine subjects, will receive three intramuscular (IM) injections of 0.5 mL of the designated study product on either Days 1, 29, and 57 or on Days 1, 29, and 180 (Table 1). Group A (unadjuvanted comparator) will receive 100 micrograms Sm-p80 alone on Days 1, 29, and 57, Group B (low dose standard schedule) will receive 10 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29 and 57, Group C (mid dose delayed booster) will receive 30 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29 and 180, Group D (mid dose standard schedule) will receive 30 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29, and 57, and Group E (high dose standard schedule) will receive 100 micrograms Sm-p80 + 5 micrograms GLA-SE on Days 1, 29 and 57. Study duration is approximately 20 months and will be conducted at one site in the US. Participant duration for subjects is 15 months. The primary objective is to assess the safety and reactogenicity following receipt of three doses of 1) 100 micrograms Sm- p80 (unadjuvanted), 2) 10 micrograms Sm-p80 + 5 micrograms GLA-SE, 3) 30 micrograms Sm-p80 + 5 micrograms GLA- SE, and 4) 100 micrograms Sm-p80 + 5 micrograms GLA-SE administered intramuscularly on Days 1, 29, and 57 and 5) 30 micrograms Sm-p80 + 5 micrograms GLA- SE administered on Days 1, 29, and 180.
Schistosomiasis is a chronic infection endemic in 74 tropical and sub-tropical countries. Sub-Saharan Africa carries the highest burden (90%) of schistosomiasis which caused by both Schistosoma mansoni and Schistosoma haematobium. The prevalence of Schistosomiasis should be assessed to control of the infection. This is usually achieved through surveys based on the use of traditional parasitological methods as urine filtration for S. haematobium. However, these traditional methods are time consuming, require an experienced technician and multiple samples due to light-infection and irregular shedding. Therefore, the point-of-care Circulating Cathodic Antigen (POC-CCA) urine test has been developed for the diagnosis of S. haematobium infection which is simple, rapid, sensitive and specific assay.
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
Schistosomiasis is a major public health issue. Clinical guidelines for the management of imported schistosomiasis are heterogeneous. The objective of this study is to describe the clinical management of schistosomiasis imported cases in France, regarding diagnosis, treatment and follow-up.
The overall objective of this project is to examine and quantify the potential existence and impact on Praziquantel (PZQ) efficacy, of naturally occurring S. haematobium and S. bovis hybrid populations in northern Senegal. Schistosome hybrids may present vigor compared to their pure parental forms and hence, may be less sensitive to PZQ. We hypothesise that PZQ repeated treatment selects the hybrid schistosome populations.
Pulmonary arterial hypertension (PAH) is a severe, progressive and potentially fatal disease that impairs the pulmonary circulation and leads to right ventricular failure. One of the world most prevalent etiologies of PAH is schistosomiasis-associated pulmonary arterial hypertension (Sch-PAH). New drugs have emerged to treat other forms of PAH, but their benefits cannot be automatically translated for Sch-PAH patients, since this etiology was not included in the pivotal PAH trials. One of the most promising therapies for the treatment of PAH to emerge in recent years is selexipag, an oral IP receptor agonist, which acts on the prostacyclin pathway. The present study aims to evaluate the efficacy, safety and tolerability of selexipague for the treatment of schistosomiasis-associated pulmonary arterial hypertension.
Groups of 3 or 7 volunteers will be exposed to a predetermined number of female Schistosoma mansoni cercariae until 10 volunteers are found infected.
Open labelled, non randomized study to evaluate the effects of Artemisinin based Combined Therapies(ACTs) on schistosomiasis since Praziquantel (PZQ) which is presently the drug of choice for treating Schistosomiasis (STS), is ineffective on immature stages and there is known parasite resistance. ACTs when combined with PZQ, targeting different stages of the life cycle has shown some effectivity.
Female genital schistosomiasis (FGS) is a frequent manifestation of the infection with Schistosoma haematobium or mansoni. FGS is probably the most neglected gynaecological condition in the tropics. Inflammation of genital tissue persists as long as adult worms are present in the circulation, and new eggs are released. Hence, lesions can only heal if the inflammation is abated and a normal immune response is restored A randomized controlled study will be carried out to compare the efficacy of the standard treatment with that of five repeated doses of praziquantel. Outcome measure is the disappearance/regression of clinical pathology at the cervix, in the vagina/vulva.
