Carrilho,F.J.; Ono-Nita,S.K.; Cardoso,R.A.; Cancado,E.L.R.; Pinho,J.R.R.; Alves,V.A.F.; Da Silva,L.C..
The purpose of the present study was to determine the frequency of hepatitis B virus (HBV) markers in families of HBsAg-positive patients with chronic liver disease. Serum anti-HBc, HBsAg and anti-HBs were determined by enzyme immunoassay and four subpopulations were considered: genetically related (consanguineous) and non-genetically related (non-consanguineous) Asian subjects and genetically related and non-genetically related Western subjects. A total of 165 and 186 relatives of Asian and Western origin were enrolled, respectively. The occurrence of HBsAg and anti-HBs antibodies was significantly higher (P < 0.0001) in family members of Asian origin (81.8%) than in family members of Western origin (36.5%). HBsAg was also more frequent among brothers...

Absence of occult hepatitis B among blood donors in southern Brazil BJID
Wolff,Fernando Herz; Fuchs,Sandra Costa; Brandão,Ajacio BM.
BACKGROUND: Occult hepatitis B virus (HBV) infection is characterized by the detection of HBV DNA in serum and/or in liver in the absence of detectable hepatitis B surface antigen (HBsAg). The reported prevalence of occult hepatitis B varies markedly among populations and according to the sensitivity of the HBV DNA assay. The aim of the present study was to describe the prevalence of occult hepatitis B among HCV-infected and non-infected blood donors in Porto Alegre, Southern Brazil, using a highly sensitive real time polymerase chain reaction (PCR) method. METHODOLOGY: Between 1995 and 1997 a sample of 178 blood donors with two positive anti-HCV ELISA tests were consecutively selected as cases, and 356 anti-HCV negative donors were selected as controls....

Giolo,Marcel Padovani; Oliveira,Christiane Minervino de; Bertolini,Dennis Armando; Lonardoni,Maria Valdrinez Campana; Gouveia,Matheus Sampaio; Netto,Daisy Pontes; Nixdorf,Suzana Lucy; Machinski Junior,Miguel.
Exposure to aflatoxins (AFs) in the diet may favour the development of hepatocellular carcinoma (HCC) and the acute exacerbation of hepatitis in chronic hepatitis B virus (HBV) carriers. Measurement of biomarkers such as aflatoxin M1 (AFM1), a metabolite of aflatoxin B1 (AFB1), in urine allows for the assessment of populations exposed to aflatoxins. The aim of this study was to investigate the occurrence of aflatoxin M1 in the urine of HBV carrier and non-carrier patients. One group included 43 randomly selected HBV carriers treated at two hospitals in the city of Maringa, Brazil, from March to June 2008. Control group consisted of 29 healthy adult volunteers with anti-HBs positive and HBsAg negative test results. Detection of AFM1 was performed by...

Zhao,Si-Hai; Liu,En-Qi; Cheng,Da-Xin; Li,Ya-Feng; Wang,Yan-Li; Chen,Yu-Long; Sun,Wen-Tao; Yan,Xi-Cai; Dang,Shuang-Suo.
The results of several new clinical trials that compared the effectiveness of entecavir (ETV) treatment with that of adefovir (ADV) treatment in patients with chronic hepatitis B (CHB) were published in recent years. However, the numbers of patients included in these clinical trials were too small to draw a clear conclusion as to whether ETV is more effective than ADV. Therefore, a new meta-analysis was needed to compare ETV with ADV for the treatment of CHB. A search of the Cochrane Central Register of Controlled Trials (CCTR), MEDLINE, the Science Citation Index, Embase, the China National Knowledge Infrastructure (CNKI), and the Wanfang Database for relevant studies published between 1966 and 2010 was performed. Trials comparing the use of ETV and ADV...

Cost-effectiveness of telbivudine versus lamivudine for chronic hepatitis B BJID
Wiens,Astrid; Venson,Rafael; Correr,Cassyano Januário; Pontarolo,Roberto.
BACKGROUND AND AIM: Chronic hepatitis B is a highly prevalent disease worldwide, leading to serious consequences if not properly treated. Six treatment options for chronic hepatitis B are currently provided by the Brazilian public health system. Telbivudine is a nucleoside analogue that is neither included in the Brazilian clinical protocol nor in the therapeutic guidelines for chronic hepatitis B. OBJECTIVE: The aim of this study was to evaluate the cost-effectiveness of telbivudine for the viewpoint of the Brazilian public system, comparing it to lamivudine. METHODS: A Markov model was used to project lifetime complications and costs of treatment with lamivudine or telbivudine for chronic hepatitis B in both HBeAg-positive and HBeAg-negative patients. To...

Bonazzi,Patricia R.; Bacchella,Telesforo; Freitas,Angela C.; Osaki,Karina T.; Lopes,Marta H.; Freire,Maristela P.; Machado,Marcel C.C.; Abdala,Edson.
Development of immunity to hepatitis B virus in cirrhotic patients waiting for liver transplantation is highly desirable. Though a double-dose regimen is available, little is know about its effectiveness. We examined the efficacy of double-dose hepatitis B virus vaccination in cirrhotic patients waiting for liver transplantation. We studied 43 patients who were waiting for liver transplantation. They were vaccinated with three doses of 40 mg hepatitis B vaccine at 0, 1 and 6 months; the normal dose is 20 mg. Efficacy was measured based on seroconversion of anti-HBs. Global response to the primary vaccination scheme was 67.5% (29 patients). Forty-one per cent of responders had anti-HBs titers above 1,000 IU/mL. No factors were associated with response,...

Epidemiology of hepatitis B virus in the cities of the northern region of Espírito Santo, Brazil Anais da ABC (AABC)
FONTES,ANDRÉ M.; ARDISSON,JULIANA S.; SOUZA,MARCO A.A.; FREITAS,RODRIGO R.; PANCOTO,JOÃO A.T..
ABSTRACT The World Health Organization (WHO) estimates that approximately 2 billion people worldwide have already had contact with hepatitis B virus (HBV) and 373 million have become chronic carriers. Hepatitis B is a major cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma, leading to a large number of deaths annually. Both viral factors and the host immune response have been implicated in the pathogenesis and clinical result of HBV infection. Many Brazilian cities, including the cities of the northern region of the state of Espírito Santo are located in regions with little health infrastructure. Our study performed an epidemiological analysis of cases of Hepatitis B in São Mateus, using methodology of Geographic Information System (GIS),...

Hepatitis B in healthcare workers: prevalence, vaccination and relation to occupational factors BJID
Ciorlia,Luiz A.S.; Zanetta,Dirce M.T..
The prevalence of hepatitis B virus (HBV) in healthcare workers (HCW) in Brazilian university hospitals is high. However, vaccination of these workers and relations with occupational factors are not well documented. A prospective study was made of 1,433 HCW and 872 administrative employees of the Hospital de Base (HB), São José do Rio Preto, SP, Brazil, and 2,583 blood donor candidates from the Hospital Blood Bank. HCW were observed from January 1994 to December 1999. Data were obtained from exams made when a worker entered hospital service, periodically and after work-related injuries. Serological reactions were analyzed in HCW who received HBV vaccine. Occupational and non-occupational information was obtained through a questionnaire. The prevalence of...

Hepatitis B virus surface antigen seroconversion in HIV-infected individual after pegylated interferon-alpha treatment: a case report J. Venom. Anim. Toxins incl. Trop. Dis.
Delicio,Adriane Maira; Abati,Paulo Afonso Martins; Vigani,Aline Gonzalez.
Hepatitis B virus (HBV) infects from 6 to 14% of HIV-infected individuals. Concurrent HIV/HBV infection occurs due to the overlapping routes of transmission, particularly sexual and parenteral. HIV-infected patients that have acute hepatitis B have six times greater risk of developing chronic hepatitis B, with higher viral replication, rapid progression to end-stage liver disease and shorter survival. The coinfection is also associated with poor response to hepatitis B treatment with interferon-alpha and increased liver toxicity to the antiretroviral therapy. Herein, we describe the case of a 35-year-old man who engages in sex with men and presented with newly diagnosed HIV-1, serological markers for acute hepatitis B and progression to chronic hepatitis B...

Silva Souza,Adaliany Cecília da; Souza Marasca,Giórgia de; Kretzmann-Filho,Nélson Alexandre; Dall-Bello,Aline; Kliemann,Dimas Alexandre; Tovo,Cristiane Valle; Veiga,Ana Beatriz Gorini da.
Abstract Infection by hepatitis B virus (HBV) is a worldwide public health problem. Chronic HBV infection with high viral replication may lead to cirrhosis and/or hepatocellular carcinoma. Mutant HBV strains, such as the HBV A1762T/G1764A double mutant, have been associated with poor prognosis and higher risk of the patient for developing cirrhosis and/or hepatocellular carcinoma. This study analyzed the presence of the HBV A1762T/G1764A double mutant in patients with chronic HBV and its association with clinical parameters such as viral load, aminotransferases, and HBV antigens. A total of 49 patients with chronic hepatitis B were included in the study, and the HBV A1762T/G1764A double mutant strain was detected in four samples (8.16%) by polymerase chain...

Zauli,Danielle Alves Gomes; Menezes,Carla Lisandre Paula de; Oliveira,Cristiane Lommez de; Mateo,Elvis Cristian Cueva; Ferreira,Alessandro Clayton de Souza.
Abstract The quantification of viral nucleic acids in serum by real-time PCR plays an important role in diagnosing hepatitis B virus and hepatitis C virus infection. In this study, we developed an assay using specific primers and probes to quantify hepatitis B virus DNA or hepatitis C virus RNA in serum from infected patients. For standardization and validation of the assay, an international panel of hepatitis B virus/hepatitis C virus and standard plasmids was used. A correlation coefficient of 0.983 and 0.963 for hepatitis B virus and hepatitis C virus, respectively, was obtained based on cycle threshold values and concentrations of DNA or RNA. The standard curve showed a linear relationship from 19 IU/mL to 1.9 × 109 IU/mL of serum, with a coefficient...

Santos,F.R.L.; Haiashi,A.R.; Araújo,M.R.T.; Abensur,H.; Romão Junior,J.E.; Noronha,I.L..
Antiviral therapies are associated with an increased risk of acute rejection in transplant patients. The aim of the present study was to evaluate the efficacy and safety of lamivudine therapy for hepatitis B virus (HBV) infection in renal transplant patients. Six patients were included in this study. They received 150 mg/day of lamivudine during a follow-up period of 24 months. The laboratory tests monitored were HBV DNA, HBsAg, HBeAg, ALT, gamma-GT, serum creatinine and blood cyclosporine levels. The HBV DNA became undetectable in four patients as early as in the third month of treatment. After six months, the viral load was also negative in the other two patients, and remained so until 18 months of follow-up. The medication was well tolerated with no...
