BACKGROUND Hepatitis E virus (HEV) can cause chronic infection with rapid progression to liver cirrhosis in immunocompromised patients. HEV seroprevalence in patients with Schistosoma mansoni in Brazil is unknown. We evaluated the prevalence of past or present HEV infection in schistosomiasis patients in Recife, Pernambuco, Brazil. A total of 80 patients(More)
The production and regulation of interleukin (IL) IL-13, IL-4 and interferon-gamma (IFN-gamma) was evaluated in 43 schistosomiasis patients with different clinical forms. Whole-blood cultures cytokine production in response to soluble egg antigen (SEA), soluble worm adult preparation (SWAP), mitogens, neutralizing antibodies or recombinant IL-13 were(More)
BACKGROUND It is suggested that interleukin (IL)-13 and transforming growth factor (TGF)-beta play a role in the pulmonary vascular changes found in animal models of schistosomiasis. The aim of this study was to assess and compare the serum levels of total TGF-beta and IL-13 of patients with schistosomiasis with pulmonary arterial hypertension (PAH) and(More)
BACKGROUND A correlation between the levels of serum globulins and the hepatic fibrosis degree in chronic hepatitis was described, but reports in schistosomiasis mansoni have not been found. OBJECTIVE To evaluate the serum globulins and IgG levels, and periportal fibrosis intensity measured by ultrasound in patients with schistosomiasis mansoni. METHODS(More)
This study was aimed to evaluate splenomegaly in patients with the hepatosplenic (HS) form of mansonic schistosomiasis (MS), analyzing the size and weight of the spleen and their relationships with patients' gender and age. Between October, 1993 to July, 1998, 78 patients with the HS form of MS had undergone splenectomy as treatment of choice for bleeding(More)
UNLABELLED Hepatopulmonary syndrome (HPS) is characterized by the presence of liver disease, arterial hypoxemia and intrapulmonary vascular dilatation (IPVD). IPVD includes diffused or localized dilated pulmonary capillaries and, less commonly, pleural and pulmonary arteriovenous communications. The aim of the present study was to investigate the occurrence(More)
Forty-five individuals with hepatosplenic schistosomiasis mansoni were studied with the aim of measuring levels of von Willebrand factor antigen (vWF:Ag), detecting abnormalities in platelet morphology and aggregation, and identifying changes to surface antigens. Haemograms, platelet aggregation tests, flow cytometry investigations of CD41/CD42b antibody(More)
BACKGROUND Schistosomiasis mansoni is an endemic parasitic disease and a public health problem in Northeast Brazil. In some patients, hepatic abnormalities lead to periportal fibrosis and result in the most severe clinical form, hepatosplenic schistosomiasis. This study aimed to evaluate whether abnormal blood coagulation and liver function tests in(More)
BACKGROUND Schistosomiasis is a tropical disease. Patients who develop hepatosplenic schistosomiasis have clinical findings including periportal fibrosis, portal hypertension, cytopenia, splenomegaly and gastrointestinal hemorrhage. OBJECTIVE The aim of this study was to analyze the hemostatic and hematologic findings of patients with schistosomiasis and(More)
In this paper, the authors review the literature and share their experience of the principal biological markers of fibrosis for the evaluation of periportal fibrosis (PPF) caused by mansoni schistosomiasis. These biological markers are compared to diagnostic ultrasound (US) scans as means of grading PPF. We also review procollagen type I and III, collagen(More)
