ABSTRACT
Hepatitis B virus (HBV) infections represent one of the major public health problems in global context. More than 2 billion people in the world have been infected with this virus at some point of time in their life and millions are chronically infected, indicating that chronic HBV-infected subjects remain as a living source of HBV transmission. The public health impact of this is tremendous. Considerable numbers of chronic HBV-infected individuals would eventually develop progressive liver diseases and their complications like hepatic failure, liver cirrhosis (LC), and hepatocellular carcinoma (HCC). Epidemiological studies have suggested that about 0.6 to 1.2 million people die annually from HBV-related liver diseases. These figures about death due to HBV and sufferings from HBV-related diseases indicate a notion of medical emergencies about HBV. In addition to these, the impact of HBV on health care delivery system moves beyond these numbers of HBV-related patients and HB-related deaths. This is because significant insights have already been developed about epidemiology, virology, and pathogenesis of HBV. Also, an effective and widely used preventive vaccine is available against HBV. In addition to these, antiviral drugs against HBV have been developed from early 1980s and several such drugs are now available commercially in the open market around the worldwide. Unfortunately, the ongoing therapeutic regimens could not stand the test of time and new insights about HBV pathogenesis are required for the development of new, novel, and evidence-based therapies for chronic HBV infections.

ABSTRACT
AIMS AND OBJECTIVES: To assess the safety and efficacy of stem cell therapy in patients with cirrhosis of the liver (LC) in the context of developing country with limited facilities for cell-based therapy and advanced technologies. MATERIALS AND METHODS: A total of 34 patients received granulocyte colony-stimulating factor at a dose of 30 IU, daily for 2 to 11 days to upregulate the numbers of white blood cells and stem cells. Subsequently, stem cells were isolated from the peripheral blood of LC patients in a closed chamber using a harvesting machine. Variable amounts of autologous stem cells were injected to LC patients for once. The patients were followed for 3 months and various factors related to safety and parameters of efficacy were analyzed in this interim report. RESULTS: Out of 34 patients available for final analysis, 3 months after the start of stem therapy, 4 patients died within this period. There was no significant alteration in biochemical parameters due to stem cell therapy, and patients also did not develop any features of acute liver failure indicating that short-term safety parameters of stem cell therapy may be acceptable. Stem cell therapy had a dominant effect on ascites of in this cohort. Although 24 of 34 patients had ascites at the start of therapy,ascites were found in 11 patients after one month and only 4 patients had ascites after 3 months. The positive role of stem cell therapy on ascites in LC patients may be attributed, even in part, to increased serum levels of albumin after therapy compared to basal levels (p <0.001). CONCLUSION: This first study about stem cell therapy in Bangladesh indicates that cell therapy may be accomplished in general hospitals of developing countries if the proper design and mild to moderate types of invasive approach is utilized. The apparent safety of administered stem cells in LC patients and the observed effect on ascites of LC patients inspire optimism about the installation of new and innovative therapy in Bangladesh. Future studies with phase I/II may with stem cell and others cell may be planned at Bangladesh in patients with LC and other intractable diseases with suitable control arms.How to cite this article: Mahtab MA, Akbar SMF, Begum M, Islam MA, Rahim MA, Noor-E-Alam SM, Alam MA, Khondaker FA, Moben AL, Mohsena M, Khan SI, Huq MZ, Munshi S, Hoque A, Haque SA.

ABSTRACT
INTRODUCTION: The overall health status of workers of tea garden of Bangladesh is below the national standard. Also, almost nothing has been reported about status of hepatitis virus infection among these population and there is also a lack of consensus. MATERIALS AND METHODS: Several health-related facts, especially those of liver diseases, were collected from 130 workers of tea garden via questionnaire. Sera were also collected from these subjects to assess positivity of hepatitis B surface antigen (HBsAg) and antibody to hepatitis C virus (anti-HCV). Hepatitis B virus (HBV) genotype was also done using genotype-specific primers in HBsAg-positive sera. RESULTS: Out of 130 tea garden workers, 5 were positive for HBsAg; however, none was reactive to anti-HCV. Genotyping of HBV deoxyribonucleic acid of 4 sera samples revealed that 2 belonged to genotype A, 1 to genotype C, and 1 to genotype D. Various risk factors were documented in HBV-infected subjects by analyzing the questionnaire. CONCLUSION: Hepatitis B virus in considerable high percentage is prevalent among workers of tea garden in Bangladesh, and immediate vaccination against HBV should be employed. Also, health education system should be accentuated in specific population like tea garden workers.How to cite this article: Al Mahtab M, Akhter S, Mollick KU, Uddin MH, Khan SI, Akbar SMF.
