Symptoms are generally mild and vague, and may include fatigue, nausea and vomiting, fever, muscle or joint pains, abdominal pain, decreased appetite and weight loss, jaundice (occurs in ~25% of those infected), dark urine, and clay-coloured stools.Liver cirrhosis may lead to portal hypertension, ascites (accumulation of fluid in the abdomen), easy bruising or bleeding, varices (enlarged veins, especially in the stomach and esophagus), jaundice, and a syndrome of cognitive impairment known as hepatic encephalopathy.The responses to treatment is measured by sustained viral response (SVR), defined as the absence of detectable RNA of the hepatitis C virus in blood serum for at least 24 weeks after discontinuing the treatment, A sustained response occurs about 65% in those with genotype 4 after 48 weeks of treatment.The evidence for treatment in genotype 6 disease is sparse and what evidence there is supports 48 weeks of treatment at the same doses used for genotype 1 disease.3.5% population infected) in Central and East Asia, North Africa and the Middle East, they are intermediate (1.5%-3.5%) in South and Southeast Asia, sub-Saharan Africa, Andean, Central and Southern Latin America, Caribbean, Oceania, Australasia and Central, Eastern and Western Europe; and they are low ( Among those chronically infected, the risk of cirrhosis after 20 years varies between studies but has been estimated at ~10–15% for men and ~1–5% for women. Once cirrhosis is established, the rate of developing hepatocellular carcinoma is ~1–4% per year.Sexual practices that involve higher levels of trauma to the anogenital mucosa, such as anal penetrative sex, or that occur when there is a concurrent sexually transmitted infection, including HIV or genital ulceration, present greater risks.Tattoos or piercings performed either before the mid-1980s, "underground," or nonprofessionally are of particular concern, since sterile techniques in such settings may be lacking.is also associated with the autoimmune disorder such as Sjögren's syndrome, lichen planus, a low platelet count, porphyria cutanea tarda, necrolytic acral erythema, insulin resistance, diabetes mellitus, diabetic nephropathy, autoimmune thyroiditis, and B-cell lymphoproliferative disorders.
Merck Sharp & Dohme, Gilead Sciences, and Abbvie were awarded contracts, which, together, are worth up to £1 billion over five years. Alter, Chief of the Infectious Disease Section in the Department of Transfusion Medicine at the National Institutes of Health, and his research team demonstrated how most post-transfusion hepatitis cases were not due to hepatitis A or B viruses.
It may be found in people with anti-hepatitis-C antibodies but with normal serum levels of liver enzymes; in antibody-negative people with ongoing elevated liver enzymes of unknown cause; in healthy populations without evidence of liver disease; and in groups at risk for HCV infection including those on hemodialysis or family members of people with occult HCV.
The clinical relevance of this form of infection is under investigation.
One barrier to finding treatments for hepatitis C is the lack of a suitable animal model.
Despite moderate success, current research highlights the need for pre-clinical testing in mammalian systems such as mouse, particularly for the development of vaccines in poorer communities.
