Pathophysiology: Hepatitis refers to an inflammatory disease which is fairly common and mainly affects the liver. Viral hepatitis is classified as A, B, C, D, E and G. All types of hepatitis viruses cause similar kind of liver damage. Inflammation happens throughout whole liver and hepatocytes are destroyed by cytotoxic cytokines and natural killer cells being part of inflammatory process. Cellular necrosis takes place but liver usually able to repair itself and regain complete function if no other complications occur.
Disease Statistics: Nearly 119,000 cases of all-cause viral hepatitis were reported in India in 2012. 290,000 cases of acute viral hepatitis were observed in 2013. Among the Indian population, there is low sero-prevalence until age 15, reaching 40% in young adults.
Treatment: Intravenous rehydration is given as supportive care but no specific emergency treatment is recommended as such. Patients are admitted in conditions of severe complications. Evaluation for hepatic encephalopathy is done. Certain patients may benefit from pharmacologic therapy. Patients are advised to avoid prolonged or vigorous physical exertion until their symptoms improve and maintain adequate hydration.
Research: One of the primary bodies working in the domain of Hepatatis is Integrated Disease Surveillance Programme of the NCDC.
