Evolution in the indications for anti-viral therapy in chronic hepatitis B / 临床肝胆病杂志

In order to reduce the disease burden of chronic hepatitis B (CHB) and improve the treatment rate of CHB, the indications for anti-viral therapy have been gradually expanded and simplified in guidelines for the prevention and treatment of CHB released by Chinese Medical Association from 2005 to 2022. This article elaborates on the evolution in the indications for anti-viral therapy in CHB from the five aspects of converging indications of HBeAg-positive and HBeAg-negative CHB, reduction in the treatment threshold of HBV DNA, reduction in the treatment threshold of serum alanine aminotransferase, emphasis on the risk factors for disease progression, and gradual loosening of the requirements for virological indicators in patients with liver cirrhosis.

Natural History and Treatment Indications of Chronic Hepatitis B / 대한소화기학회지

HBV is the most common etiology of both liver cirrhosis and hepatocellular carcinoma in Korea. Despite much progress made, the currently available antiviral therapies cannot eradicate or eliminate this virus. Hence, the benefits and risks of antiviral therapy should be carefully evaluated on an individual basis and within the context of the clinical situation. The ultimate goals of treatment are to decrease the mortality from liver disease. The benefits of antiviral therapy come from prevention of progression of liver disease. Understanding the natural history of chronic HBV infection is a key step in the decision making process to treat patients with chronic HBV infection. Generally, chronic hepatitis B patients in the immune tolerant phase and immune inactive phase are not recommended to undergo antiviral treatment, except for those patients in special conditions (e.g., immunosuppression or anticancer chemotherapy). Chronic hepatitis B patients in the immune active phase are recommended for antiviral therapy. For patients with liver cirrhosis, treatment should be considered when serum HBV DNA is detectable regardless of the serum level of ALT.

New perspectives on the natural history and growth pattern of hepatic hemangioma in adults: a cohort study / 中华肝胆外科杂志

Objective To investigate the natural history and growth pattern of hepatic hemangioma in adults.Methods From April 2010 to March 2013, adult patients with hepatic hemangioma who had no prior treatment were enrolled.A routine follow-up was performed to observe the natural history and complications of these lesions.Results 236 patients were enrolled in the study.The median size of the hemangiomas was 4.5 cm (range 0.6 ～ 19.2 cm).During a median follow-up of 48 months (range 3 ～ 266 months), the hemangiomas increased in size in 61.0％ of patients, remained stable in size in 23.7％, decreased in size in 8.5％.The peak growth period was in patients ＜ 30 years age (0.46 ± 0.41 cm/year) and the growth rate decreased significantly after 50 years of age (0.21 ±0.40 cm/year).Hemangiomas with a size ＜2.0 cm had the lowest growth rate (0.16 ± 0.42 cm/year).The peak growth rate was in hemangiomas 8.0 ～ 10.0 cm (0.80 ± 0.62 cm/year) , but for hemangiomas ＞ 10.0 cm, the growth rate was only (0.47 ±0.91)cm per year.Only 9 patients had severe symptoms caused by the hemangioma.No patients presented with hemangioma-related complications.Conclusions The majority of hepatic hemangiomas have the tendency to increase in size but they rarely caused complications.All the hemangiomas could be safely managed by observation, and surgery should only be considered in patients with complications.

The management of chronic hepatitis C / 대한내과학회지

Hepatitis C virus (HCV) infection remains a serious health problem, and an estimated 170 million people are infected worldwide. Hepatitis C is the principal cause of death from liver disease and is the one of the main indications for liver transplantation. The primary goal in the treatment of HCV infection is to reduce mortality by preventing liver-related deaths associated with the development of hepatocellular carcinoma and decompensated cirrhosis. PEGylated interferons, together with ribavirin, are currently the standard of care for patients with chronic hepatitis C. This review discusses the current indications and standard treatment of hepatitis C virus infection.
