OBJECTIVE To estimate the incidence of acute sporadic viral hepatitis and describe its epidemiology in an urban population. DESIGN A retrospective community survey for jaundice cases. SETTING Headquarter town of a tribal district, Bastar, in Madhya Pradesh state, India. METHOD Trained paramedics surveyed about 51,643 population to detect cases of jaundice which occurred in the past one ye...

BACKGROUND Perinatal and horizontal are the common modes of transmission of hepatitis-B virus in children. CASE CHARACTERISTICS Two mother-child pairs with children having received multiple blood transfusions in past. OBSERVATION Both the mothers developed acute hepatitis-B infection whereas children were demonstrated to be having chronic infection with hepatitis-B. OUTCOME One mother cle...

background meningitis is an inflammation of the membranes, which surround the brain and spinal cord. early treatment of bacterial meningitis can prevent serious complications. in the last two decades, three vaccines have been developed against the three main bacterial species implicated in meningitis of children in western countries and vaccine-preventable invasive bacterial meningitis has decr...

The pathogenetic mechanisms for liver damage in acute hepatitis C are not clear, but a host immune cellular response may be involved. In chronic hepatitis C, there is strong evidence that host cellular immune response is involved in the control of viral replication and contributes to hepatocellular damage. As hepatitis C virus infection persists, continuous liver damage and regeneration, togeth...

viral hepatitis, as an international public health concern, seriously affects communities and health system. in recent years, great strides have been taken for development of new potential tools against viral hepatitis. among these efforts, a valuable strategy introduced new molecules called “aptamers”. aptamers as potential alternatives for antibodies could be directed against any protein in i...

UNLABELLED Despite its importance in shaping adaptive immune responses, viral clearance, and immune-based inflammation, tissue-specific innate immunity remains poorly characterized for hepatitis C virus (HCV) infection due to the lack of access to acutely infected tissues. In this study, we evaluated the impact of natural killer (NK) cells and myeloid (mDCs) and plasmacytoid (pDCs) dendritic ce...

The activities of the interferon-induced enzyme 2'-5' oligoadenylate synthetase in peripheral blood mononuclear cells were determined in patients with viral hepatitis. Increased levels of the enzyme were found in patients with acute type B hepatitis at the early phase and also in those with chronic type B hepatitis at the active stage. The levels of this enzyme activity were not significantly i...

Standard medical education dictates that the vast majority of cases of an alanine aminotransferase (ALT) level >1,000 IU/l will be due to acute ischaemia, acute drug-induced liver injury (DILI) (usually paracetamol) or acute viral hepatitis. There are very few references in the literature to other potential causes of an ALT >1,000 IU/l nor to the prognosis ascribed to each aetiology. In this st...

Aplastic anemia following viral hepatitis is a condition well recognized in the medical literature. Although hepatitis-associated aplastic anemia is an uncommon syndrome, there are several reports in the literature describing such cases. In these reports, aplastic anemia generally occurs following a viral infection, including parvovirus B19, but may also be idiopathic. The etiology of both the ...

background more than two billion people have been exposed to hepatitis b virus (hbv) worldwide. furthermore, four hundred million of them are infected with chronic hbv infection. the predominant mutation of the precore region involves a g to a change at nucleotide1896, which creates a premature stop codon at codon 28. two mutations of a1762t and g1764a are reported as the most prevalent mutatio...
