SUMMARYPurpose: To evaluate the frequency and the consequences of the co-infection of hepatitis B and C viruses in patients with hepatosplenic schistosomiasis (HSS).Methods: B and C serologic markers, exposure to risk factors, biochemical assays, upper gastrointestinal endoscopies, and abdominal ultrasonograms were evaluated in 101 patients with HSS from 1994 to 1997. Whenever possible, PCR was tested and histopathological studies were reviewed.Results: At least one HBV virus marker was found in 15.8%, and anti-HCV was detected in 12.9% of the subjects. The seropositive subjects tended to be older than the seronegative ones. A history of blood transfusion was significantly related to the presence of anti-HCV. Three (18.75%) out of 16 subjects exposed to B virus were HBsAg positive. Eleven (84.6%) out of thirteen patients who were anti-HCV positive demonstrated viral activity. Patients with ongoing viral infection presented a higher average level of liver aminotransferases, a higher frequency of cell decompensation and a higher rate of chronic hepatitis. Portal hypertension parameters were not influenced by viral exposure. Conclusions:The rate of hepatitis B and C viruses serologic markers observed in the patients with HSS was higher than the control group. The co-infection was responsible for a higher frequency of cell decompensation.

“…Another relevant fact is that the studies performed in endemic areas, mainly Brazil and Egypt [10][11][12][13][14]23], include a high proportion of cirrhotic patients (from 31.5 to 48 %). On the contrary, in our series there were very few cirrhotic patients.…”

“…Several studies performed in areas of high endemicity for HBV and/or hepatitis C virus (HCV) and schistosomiasis (especially for S. mansoni) [10][11][12][13][14][15] have reported that coinfection with either HBV or HCV may significantly worsen the evolution of the schistosomal hepatosplenic disease.…”

Schistosomiasis is related to the development of liver fibrosis and portal hypertension. Chronic co-infection with HBV and Schistosoma has been associated in endemic areas with a higher risk for a more severe liver disease. However, no studies have assessed the real importance of this co-infection in non-endemic regions. This is a retrospective observational study of Sub-Saharan immigrants attending between October 2004 and February 2014. Patients with chronic HBV infection with and without evidence of schistosomal infection were compared. Epidemiological, analytical, and microbiological data were analysed. Likelihood of liver fibrosis based on APRI and FIB-4 indexes was established. A total of 507 patients were included in the study, 170 (33.5 %) of them harbouring evidence of schistosome infection. No differences were found in transaminase, GGT, and ALP levels. In fibrosis tests, a higher proportion of patients with HVB and S. mansoni detection reached possible fibrosis scores (F > 2) when compared to patients without schistosomiasis: 17.4 vs 14.2 % and 4.3 % vs 4.2 % (using high sensitivity and high specificity cut-offs respectively), although differences were not statistically significant (p = 0.69, p = 0.96). For possible cirrhosis (F4) score, similar results were observed: 4.3 % of co-infected patients vs 2.1 % of mono-infected ones, p = 0.46. According to these datas, in non-endemic regions the degree of hepatic fibrosis in patients with chronic hepatitis B is not substantially modified by schistosome co-infection.

“…Blood transfusions performed some decades ago resulted in infection with the hepatitis B or C virus; currently, many patients present with mixed liver disease (MLD), defined as HSS accompanied by viral hepatitis. (12,13) There have been no studies investigating the occurrence of HPS in this group of patients.…”

Objective: To determine the occurrence of hepatopulmonary syndrome (HPS) in patients with cirrhosis who are candidates for liver transplantation; to compare demographic, clinical, laboratory, and spirometric characteristics, as well as echocardiography results, arterial blood gas analysis, and severity of liver disease between the groups of patients with and without HPS; and to describe the occurrence of HPS in the subgroup of patients with cirrhosis and schistosomiasis mansoni (mixed liver disease). Methods: Between January and November of 2007, we evaluated 44 patients under treatment at the Liver Transplant Outpatient Clinic of the Federal University of Pernambuco Hospital das Clínicas, in the city of Recife, Brazil. The diagnostic criteria for HPS were intrapulmonary vascular dilatation, identified by transthoracic echocardiography, and an alveolar-arterial oxygen tension difference ≥ 15 mmHg or a PaO 2 < 80 mmHg. Results: The mean age of the patients was 52 years, and 31 patients (70%) were males. The most common cause of cirrhosis was alcohol use. Schistosomiasis was present in 28 patients (64%). Of the 44 patients, 20 (45.5%) were diagnosed with HPS. No significant differences were found between those patients and the patients without HPS in terms of any of the characteristics studied. Of the 28 patients with cirrhosis and schistosomiasis, 10 (35.7%) were diagnosed with HPS. Conclusions: In the population studied, HPS was highly prevalent and did not correlate with any of the variables analyzed.Keywords: Hepatopulmonary syndrome; Liver transplantation; Liver cirrhosis; Hypertension, portal; Schistosomiasis mansoni; Echocardiography. ResumoObjetivo: Verificar a ocorrência da síndrome hepatopulmonar (SHP) em pacientes cirróticos candidatos a transplante de fígado; comparar as características demográficas, clínicas, laboratoriais e espirométricas, resultados de ecocardiografia, análise de gases arteriais e da gravidade da doença hepática nos pacientes com e sem SHP; e descrever a ocorrência de SHP no subgrupo de pacientes com cirrose associada à esquistossomose mansônica (doença hepática mista). Métodos: Entre janeiro e novembro de 2007, foram avaliados 44 pacientes inscritos no Ambulatório de Transplante Hepático do Hospital das Clínicas da Universidade Federal de Pernambuco, em Recife (PE). Os critérios diagnósticos para SHP foram a presença de dilatações vasculares intrapulmonares, identificadas por ecocardiografia transtorácica, assim como diferença alveoloarterial de oxigênio ≥ 15 mmHg ou PaO 2 < 80 mmHg. Resultados: A idade média foi 52 anos, e 31 pacientes (70%) eram do sexo masculino. A causa mais frequente de cirrose foi uso de etanol. A esquistossomose esteve presente em 28 pacientes (64%). Dos 44 pacientes, 20 (45,5%) foram diagnosticados com SHP. Não foram observadas diferenças significativas em relação às características estudadas. No subgrupo de pacientes com cirrose associada à esquistossomose, 10/28 (35,7%) receberam o diagnóstico de SHP. Conclusões: A SHP apresentou elevada prevalênc...
