Viral hepatitis is affecting about 400 million people, out of which one third cases are due to Hepatitis-C Virus (HCV) alone. In Pakistan about 10 million people, which is about 6 percent of the total population, is affected with hepatitis- C.
This was stated at a lecture jointly organised by Dr Panjwani Centre for Molecular Medicine and Drug Research (PCMD).
It was pointed out that Hepatitis is an inflammation of the liver generally due to viral infection or due to some metabolic abnormalities.
In his lecture Professor Dr Aqeel Ahmed of the Department of Microbiology, University of Karachi, expressed the apprehension that mortality rates due to hepatitis-C are expected to go up in future. A Karachi University statement on Sunday said that the topic of his talk was 'HCV: Disease and Prevention'. It was jointly organised by PCMD and Virtual Education Project Pakistan (VEPP), as a part of series of popular lectures for public awareness on common diseases of Pakistan. Health professionals, students, research scholars, NGO representatives and general public attended the lecture.
Professor Ahmed said that hepatitis is inflammation of the liver generally due to viral infection caused by hepatitis viruses; these unrelated viruses have different epidemiologic profiles and are transmitted through different routes, which are either water-borne, or spread through the blood, blood products or unethical medical or social practices.
He said that Hepatitis viruses produce inflammation in the liver, resulting in clinical illness characterised by fever, and often non-specific symptoms like pain in abdomen, loss of appetite, nausea, vomiting and jaundice, he said, adding more than 70 percent of HCV infected patients become chronic, which may lead to death of patient. Professor Ahmed said that this has immense financial implications, so early detection and treatment of Hepatitis- C is recommended. Genotypes 3a and 3b, amongst 11 genotypes of hepatitis, are found to be the most common genotypes in some regions of the world.
He stated that patients with these genotypes also had good chances of response rate to therapy. There are some host-factors attributed to increased risk of HCV infection, including older age, male gender, co-infection with HIV, HBV. Other factors such as alcohol consumption, iron overload and hepatotoxic medicines also have damaging effects. Patients with chronic hepatitis 'C' can develop many extra hepatic symptoms like rheumatoid arteritis, keratoconjunctivitis sicca, glomerulonephritis and lymphoma, which are probably due to altered immune response.
