3.Occult Hepatitis B Virus Infection in Chronic Hepatitis C.
The Korean Journal of Gastroenterology 2013;62(3):154-159
Occult HBV infection is defined as the presence of HBV DNA in the liver (with or without detectable or undetectable HBV DNA in the serum) of individuals testing negative for HBsAg. Studies on occult HBV infection in hepatitis C patients have reported highly variable prevalence, because the prevalence of occult HBV infection varies depending on the hepatitis B risk factors and methodological approaches. The most reliable diagnostic approach for detecting occult HBV detection is through examination of liver DNA extracts. HCV has been suspected to strongly suppress HBV replication up to the point where it may be directly responsible for occult HBV infection development. However, more data are needed to arrive at a definitive conclusion regarding the role of HCV in inducing occult HBV infection. Occult HBV infection in chronic hepatitis C patients is a complex biological entity with possible relevant clinical implications. Influence of occult HBV infection on the clinical outcomes of chronic hepatitis C may be considered negative. However, recent studies have shown that occult HBV infection could be associated with the development of hepatocellular carcinoma and contribute to the worsening of the course of chronic liver disease over time in chronic hepatitis C patients. Nevertheless, the possible role of occult HBV infection in chronic hepatitis C is still unresolved and no firm conclusion has been made up until now. It still remains unclear how occult HBV infection affects the treatment of chronic hepatitis C. Therefore, in order to resolve current controversies and understand the pathogenic role and clinical impacts of occult HBV infection in chronic hepatitis C patients, well-designed clinical studies are needed.

Hepatitis A is generally known as a mild, self-limiting disease of the liver, but in rare instances it can progress to fulminant hepatitis, which may require liver transplantation for recovery. Such cases are known to be related to old age and underlying liver disease. We report four cases of hepatitis A in which patients presented with fulminant hepatitis and acute renal failure and underwent liver transplantation. The following common features were observed in our cases: (1) occurrence in relatively old age (> or =39 years old), (2) association with acute renal failure, (3) presence of hepatomegaly, and (4) microscopic features of submassive hepatic necrosis.

Liver fibrosis is a slow, insidious process involving accumulation of extracellular matrix protein in the liver. The stage of liver fibrosis in chronic liver disease (CLD) determines overall morbidity and mortality; the higher the stage, the worse the prognosis. Noninvasive composite scores can be used to determine whether patients with CLD have significant or advanced fibrosis. Patients with low composite scores can be safely followed up in primary care with periodic reassessment. Those with higher scores should be referred to a specialist. As the epidemic of diabetes mellitus, obesity and non-alcoholic fatty liver diseases is rising, CLD is becoming more prevalent. Easy-to-use fibrosis assessment composite scores can identify patients with minimal or advanced fibrosis, and should be an integral part of decision-making. Patients with cirrhosis, high composite scores, chronic hepatitis B with elevated alanine aminotransferase and aspartate aminotransferase, or deranged liver panel of uncertain aetiology should be referred to a specialist.

We report here a case of acute hepatitis A, which was complicated by Guillain-Barr? syndrome (GBS). A 32-year old male admitted to our hospital with the symptoms of acute hepatitis and was diagnosed to have acute hepatitis A with positive IgM anti hepatitis A virus antibody. On 9th day after the onset of jaundice, acute progressive, ascending, symmetric motor paralysis were developed and eventually respiratory failure ensued. Cerebrospinal fluid analysis showed albumino-cytologic dissociation and nerve conduction velocity test suggested a polyradiculopathy. He was diagnosed to have GBS and treated with intravenous immunoglobulin and required a ventilatory support. After 90 hospital days, he recovered in ambulatory condition with the aid of crutches. The clinical course, prognosis and the outcome of neuropathic symptoms of GBS following acute hepatitis A were relatively poor in our case.

Acute disseminated encephalomyelitis (ADEM) is a monophasic autoimmune demyelinating disease of the central nervous system, which typically follows acute viral or bacterial infection or vaccination. We report a case of ADEM associated with hepatitis C virus (HCV) infection with positive serum and cerebrospinal fluid (CSF) anti-HCV antibody. After steroid treatment, neurologic symptoms were improved. Virus triggers autoimmunity or direct viral invasion plays a part in the genesis of ADEM. This is the first reported case of ADEM with anti-HCV antibody in the CSF.
