Viral Hepatitis - What's New | Dr Ponni Krishnan G

Summary

Key Points

• Hepatitis is an inflammation of the liver, most commonly caused by hepatotropic viruses like Hepatitis A through E, but also by alcohol, drugs, and other infections. 5:10
• Viral hepatitis can be acute (less than six months) or chronic (more than six months), with Hepatitis A and E typically presenting acutely, while B, D, and C are more prone to chronicity. 6:18
• The video emphasizes the importance of early diagnosis, supportive care, and adherence to national programs for managing viral hepatitis effectively. 10:33
• The national viral hepatitis control program, launched in 2018, aims to combat hepatitis and achieve elimination of Hepatitis C by 2030, while reducing morbidity and mortality associated with Hepatitis B and C. 14:17
• Diagnosis of Hepatitis B involves various serological markers like HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc IgM, and HBV DNA, which indicate infection status, replication, and immune response. 25:58
• Treatment for Hepatitis B includes antiviral drugs such as tenofovir and entecavir, with lifelong treatment often necessary for patients with cirrhosis or detectable viral load. 30:43
• The Hepatitis B vaccine is a safe and effective subunit vaccine administered in a three-dose series, crucial for preventing mother-to-child transmission and general infection. 34:27
• Hepatitis B is a DNA virus that can lead to chronic liver disease, cirrhosis, and hepatocellular carcinoma, with transmission primarily through parenteral routes. 36:15
• Hepatitis C is an RNA virus, a major cause of chronic liver disease, cirrhosis, and liver cancer, with an estimated 6 to 12 million carriers in India. 36:23
• Diagnosis of Hepatitis C relies on detecting HCV RNA, and treatment with directly acting antiviral agents offers high cure rates (95-99%) for individuals over 18 years old. 38:35
