Keyword analysis revealed that viral hepatitis research on SEA is mainly focused on evaluation of treatment, vaccines, and epidemiology of disease. Thailand, Singapore, and Malaysia are the highest generators of viral hepatitis research in SEA. Region of birth might also confound the association between remoteness and HCC, since there are much higher proportions of Asian born people in metropolitan areas than non-metropolitan areas. An American study indicated that the risk of HCC in diabetic patients was more than twice that in non-diabetics, and there have been some similar findings in Taiwan. In summary, this study has identified and quantified important risk factors for HCC within a high-risk, population-based cohort. This is particularly likely to be a factor among the HBV-infected cohort. Two studies based in Taiwan found a 12-fold and 50-fold increase in risk due to cirrhosis among a HBV-infected cohort. The observed increased risk of HCC among those with HBV/HCV co-infection is consistent with other studies, which found that the combined effect of the two infections is more than additive, but less than multiplicative. The HCC incidence was doubled in diabetics compared with controls (21.0 versus 10.4 per 10,000 person-years), which translated to an adjusted hazard ratio of 1.73, the team found.
The baseline prevalence of biochemical signs and histological features of autoimmune gastritis was similar to that found in the general population. The prevalence of autoimmune gastritis in chronic HCV patients is currently unknown. 60s, rather than late 70 s or beyond, possibly due to variation in the prevalence of certain risk factors between regions. Untreated chronic hepatitis due to HCV causes cirrhosis in 20 to 30% of patients, although development may take decades and varies because it is often related to a patient's other risk factors for chronic liver disease, including alcohol use and obesity. After adjustment, metformin use was associated with significant protection (hazard ratio, 0.49). This was also true of thiazolidinediones (hazard ratio, 0.56). Taking insulin, sulfonylureas, and other agents also reduced the risk, but not significantly. Pregnancy: Adequate human data on use during pregnancy. How do human blood types work? Hepatitis C virus (HCV) is transmitted by blood to blood. After the exposure (especially if the blood exposure involved another person known to have the hepatitis C virus), it is recommended that testing for the hepatitis C antibody be performed at 4 to 6 months after the exposure OR that testing for the hepatitis C virus itself (a test often called an HCV PCR or hepatitis C viral load test) be performed 4 to 6 weeks after the potential exposure.
The association with older age highlights the potential impact of HBV and HCV screening of at-risk groups and early clinical assessment. The incidence of HCC increased with age and comorbidity score, and was higher among males, metropolitan residents, and those with ALD, and particularly cirrhosis. The risk of HCC was observed to increase significantly with age for both HBV- and HCV-infected groups. While including diabetes in the models suggested an increase in the risk of comparable magnitude, the difference was not sufficiently significant to remain in the final model, suggesting that in our cohort, this is a low-risk condition relative to other factors considered. Co-infection with HBV and HCV was associated with increased HCC risk in the HCV cohort, and of all risk factors considered, cirrhosis conferred the greatest additional risk, regardless of infection type. NEW YORK (Reuters Health) Dec 26 - Cirrhosis and hepatitis are associated with the occurrence of hepatocellular carcinoma (HCC) in patients with diabetes, and hepatitis C is of particular importance, Taiwanese researchers report in a November 15 online paper in The American Journal of Gastroenterology. In conclusion, IFN treatment for chronic hepatitis C does appear to be associated with frequent occurrence of autoimmune gastritis, particularly in female patients.
Also, linked treatment data were not available for this study, which eliminated the possibility of examining the extent to which antiviral therapy reduces HCC risk; however, this might form the basis of future studies when additional data permit. More limited access to specific HCC diagnostic services in non-metropolitan areas might also be a factor in producing an apparently lower incidence of HCC. Each comorbid condition influences the risk of HCC by varying degrees, and multiple conditions might interact in complex ways. Having a hospital record for both conditions likely indicates advanced or rapidly-progressing liver disease. Few studies have assessed the association between comorbidity score and HCC risk, as it is often more informative to examine individual health conditions. This has made the need for Rhiannon's surgery more urgent. However, in terms of identifying high-risk individuals, the comorbidity score quantifies the combined effect of multiple conditions, without the need to interpret risks associated with multiple factors and their interactions. Identifying and quantifying risk factors specific to a population, as we have done, forms an integral part of targeting cost-effective surveillance and provides motivation for more widespread screening of high-risk groups. A combination of surveillance and treatment has been shown to be a more cost-effective way to reduce the burden of liver cancer than surveillance alone.
