As shown in Table 3, the prevalence
of chronic hepatitis C in Viet Nam has been estimated to range from only 1.0% in low-risk groups to as high as 87% in high-risk groups. In the study already mentioned that assessed blood test results from all patients visiting 12 hospitals in Viet Nam from 2005 to 2008 (excluding high-risk patients) the HCV prevalence was found to be 2.89%.8 The prevalence in patients with liver disease has been reported to be much higher, with one study showing that 23% of liver disease patients in Ho Chi Minh City were seropositive for HCV antibodies, with detectable HCV-RNA in 61% of these.10 In another study, HCV-RNA was detected in 19.2% of liver disease patients, with 7.7% reported to be coinfected with both HBV and HCV.1 The prevalence of HCV is particularly http://www.selleckchem.com/products/Temsirolimus.html high in drug users (87%) and patients who require Selleck BAY 57-1293 medical treatment that potentially exposes them to HCV through contaminated medical devices or blood products, including patients on maintenance hemodialysis (54%) and those with hemophilia (29%).2 Nosocomial transmission of HCV is high in developing countries because too often contaminated syringes and needles are re-used in medical, paramedical and dental procedures.19,20 Community re-use of needles for tattoos is also common. In one study of patients without liver disease, the two main risk factors associated with HCV acquisition were hospital
admission and tattoos.21 Approximately 25% of people with chronic HCV will eventually develop cirrhosis,22 and a substantial percentage will subsequently develop HCC. As with CHB, most people with CHC will remain symptom-free and unaware that they are infected until a late disease stage when they develop obvious signs of cirrhosis or HCC. Thus, screening with an antibody test to allow for early and accurate diagnosis is essential. It will be important to provide simplified guidelines to health-care workers for proper diagnosis of CHC, including use of confirmatory tests, such as HCV-RNA quantification, as well as for appropriate treatment. Alcoholic liver disease (ALD) is another major contributor to the overall
burden of liver disease in Viet Nam. A recent study of nine sites in 上海皓元 five Asian countries found very high rates of alcohol consumption by men in Viet Nam.5 In fact, of the nine sites assessed, the two in Viet Nam had by far the highest rates (31.4% and 17.3%) of male at-risk drinkers, defined as men consuming five or more standard drinks per day. Another 53.2% and 68.5% of men at the two sites in Viet Nam were rated as moderate drinkers (consuming up to four drinks per day). As part of the overall approach to liver disease, it will be important to educate health-care workers about alcoholic liver disease and about the resources available for addressing it. When alcoholic liver disease is apparent, it will be appropriate for health-care workers to refer patients to counseling and alcohol support groups.
