Low Viral Load Does Not Exclude Significant Liver Damage in Patients with Chronic HBV Infection in Bangladesh

<p><strong>Background: </strong>In general, it is assumed that patients with chronic hepatitis B virus (HBV) infection with high viral load exhibit increased liver damages. Accordingly, the treatment guidelines emphasize on reducing viral load in chronic HBV carriers. The ethical and scientific basis of these observations was mainly accumulated from investigations from developed countries of the world. More than 80% chronic HBV carriers live in the developing nations of the world, but little is known about relationship between HBV viral load and extent of liver damages in these countries. In this study, we addressed this issue to provide insights about this.</p> <p><strong>Methods: </strong>In this retrospective study we reviewed the records of 210 chronic hepatitis B (CHB) patients from our pool of 561 Bangladeshi CHB patients. All of these 210 patients had low HBV DNA (&lt;10⁵ copies/ml by PCR). Of them 16 were HBeAg +ve and rest 194 HBeAg -ve. They have also been tested for other serologic markers of HBV (i.e. HBsAg, anti-HBe), HCV (i.e. anti-HCV) and serum alaninetransaminase (ALT) level. All patients also underwent per-cutaneous liver biopsy.</p> <p><strong>Results: </strong>37.5% (6/16) HBeAg +ve patients with low HBV DNA had significant hepatic necro-inflammation (HAI-NI &ge;7), whereas this figure was 31.44% (61/194) in case of HBeAg -ve patients. On the other hand significant hepatic fibrosis (HAI-F &ge;3) was observed in 31.25% (5/16) and 14.4% (28/194) in HBeAg +ve and -ve patients respectively.</p> <p><strong>Conclusion: </strong>This study shows that a correlation could not be established between viral load and liver damage in patients with CHB in Bangladesh. A significant percentage of patients with low HBV DNA may have marked hepatic necro-inflammation and fibrosis, more so in case of HBeAg +ve CHB. Further study may be needed to find out the influence of other factors on liver damages in CHB patients in developing nations like Bangladesh, where about 8 million chronic HBV carriers are living. Most of these patients have not been characterized and treatment modalities have not been defined for them. Our study may suggest the research direction for management of these cases.</p> <p><strong>Key Words: </strong>Low HBV DNA; Chronic hepatitis B; Hepatic necro-inflammation; Hepatic fibrosis.</p><p>DOI: 10.3329/bsmmuj.v1i1.3693</p> <p><em>BSMMU J </em>2008; 1(1): 19-21</p>

Case Report of Autoimmune Hepatitis from a Tertiary Centre in Bangladesh

Autoimmune hepatitis is defined as chronic liver disease of unknown aetiology with aberrant autoreactivity and genetic predisposition, characterized by female predominance, circulating auto-antibodies, hypergammaglobulinaemia and association with HLA DR3 and HLA DR4 [1]. We present two patients with autoimmune. The first patient is a young lady who was diagnosed with autoimmune chronic hepatitis. The second patient, on the other hand, is an elderly gentleman who presented to us with autoimmune hepatitis related decompensated cirrhosis of liver. doi: 10.3329/blj.v1i1.2652 Bangladesh Liver Journal Vol.1(1) 2009 p.53-54
