The importance of the serum quantitative levels of hepatitis B surface antigen and hepatitis B e antigen in children with chronic hepatitis B.
We aimed to investigate the clinical importance of quantitative levels of serum hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg), and to detect their correlation with hepatitis B virus (HBV) DNA load, alanine aminotransferase (ALT) levels, hepatic activity index (HAI) and fibrosis scores. ⋯ The present study indicated that HBsAg and HBeAg levels significantly decreased during treatment and that HBeAg correlated with HBV DNA load. Quantitative HBeAg and HBsAg assays could therefore have an important role in treatment of CHB.

Diagnostic value of the JAK2 V617F mutation for latent chronic myeloproliferative disorders in patients with Budd-Chiari syndrome and/or portal vein thrombosis.
The diagnosis of an underlying myeloproliferative neoplasm (MPN) is often problematic in patients with Budd Chiari syndrome (BCS) or portal vein thrombosis (PVT). This study aimed to assess the diagnostic value of the JAK2 gene V617F gain-of-function mutation for MPN in splanchnic vein thrombosis patients. ⋯ The JAK2 V617F mutation is a noninvasive molecular marker for occult MPNs and can be used for the diagnosis of latent MPNs presenting with thrombotic events. Analysis of JAK2 mutation in the patients with idiopathic PVT or BCS showed that 20% had latent MPNs. In addition to this JAK2 mutation, prothrombotic events were observed in a significant number of patients with splanchnic vein thrombosis. JAK2 gene analysis should be included in the research panel for BCS and PVT patients without cirrhosis.
