Filter by: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.
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.
Randomized Controlled Trial: The investigational materials used in this trial were administered to subjects each day by trained clinicians. Primary Objectives: - assess the effect of dietary supplementation with arachidonic acid on the cure rates for Schistosomiasis mansoni with and without concomitant treatment with praziquantel. - assess the safety of dietary supplementation using arachidonic acid in children with clinically confirmed schistosomiasis mansoni infection. Secondary objective: - to measure changes in total phospholipids in plasma.
NIDIAG is an international collaboration on integrated diagnosis-treatment platforms, funded by the European Commission (EC). NIDIAG aims to develop an improved, patient-centred system for delivering primary health care in resource-constrained settings. NIDIAG will investigate three clinical syndromes, namely (i) persistent digestive disorders, (ii) persistent fever and (iii) neurological disorders, due to neglected tropical diseases (NTDs). The current study focuses on persistent digestive disorders, which are defined as diarrhoea or abdominal pain that last for at least 2 weeks. While acute diarrhoea has been studied globally, few research activities have focused on the epidemiology, diagnosis and treatment of long-lasting diarrhoeal episodes (2 weeks and longer) in the tropics. The spectrum of possibly involved pathogens includes more than 30 bacterial, parasitic and viral infectious agents. This lack of data may be explained by the fact that people suffering from NTDs might only seek care at a late stage of the disease. Furthermore, health systems in affected regions are often weak and their primary health-care centres are often under-staffed and lack essential diagnostic equipment. The hypothesis of this study is that development of an evidence-based syndromic approach can lead to better diagnosis and management of NTDs in patients with persistent digestive disorders. The study will be carried out in two West African countries (Côte d'Ivoire and Mali) and in two Asian countries (Indonesia and Nepal). The study will follow a "case-control" design and patients and controls will be prospectively enrolled. In order to address the knowledge gaps, three specific objectives will be pursued. First, the contribution of NTDs to the 'persistent digestive disorders syndrome' will be assessed. Second, the value of clinical features and rapid diagnostic tests (RDTs) for the diagnosis of target NTDs that give rise to persistent digestive disorders will be determined. Third, the clinical response to standard empiric and targeted treatment of several NTDs in patients with persistent digestive disorders will be evaluated. These objectives will provide a long-term benefit for the communities by improving the clinical decision-making process for the target NTDs and thus, better diagnostic work-up and patient management can be achieved in the study countries and other similar resource-constrained countries
cardiopulmonary exercise test evaluate patients with pulmonary hypertension before and after medical or balloon pulmonary angioplasty treatment
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.
Previous research undertaken among adults in high endemic districts of Busia, Adjumani, Moyo and Nebbi reported unwillingness to take preventive treatment. A particular study conducted in primary schools of Jinja district showed that only 30% of school children took praziquantel during the 2011 Mass Drug Administration (MDA). Fear of side effects of praziquantel, lack of knowledge about schistosomiasis transmission and prevention and lack of teacher support were some of the major factors associated with the low uptake. Similar reasons for non-uptake have been reported elsewhere. Thus, measures are needed to increase uptake of Mass Drug Administration (MDA) in Uganda. There is no doubt that health education facilitates a better understanding of the obvious risks to health, including the knowledge of preventing parasitic infections among primary school children. Better compliance to treatment for schistosomiasis among school children can be achieved through implementing carefully designed programs involving face to face education methods. Increasing knowledge about schistosomiasis transmission and prevention and implementing measures to mitigate the side effects attributable to praziquantel, such as providing a snack prior to drug administration may improve uptake of the drug among school children. Hypothesis- Provision of a pre-treatment snack is effective in improving uptake of preventive treatment for intestinal schistosomiasis among primary school children.
The purpose of this study is to evaluate the impact of praziquantel for the treatment of Schistosoma haematobium infection among schoolchildren in Al Salamania in Central Sudan.
SchistoVAN aims to study the role of schistosomiasis infection in the modulation of the immune response of children to childhood vaccine antigens, as well as the impact of this infection on their nutritional status and their haemoglobinaemia.
