Traditional nutritional assessment, although easier, underestimated the prevalence and severity of malnutrition in patients with cirrhosis. The underestimation was more pronounced in Child's class A and B patients.
A significant number of patients with chronic HCV infection had elevated serum GGT levels. Furthermore, this enzyme seemed to be useful as an indirect marker of more advanced liver disease in chronic hepatitis C.
HBV isolates with the identified substitutions have the potential to spread silently by nosocomial transmission within the hemodialysis unit. These results have potential implications for the management of patients with occult HBV infection undergoing hemodialysis.
ELF panel is a good noninvasive fibrosis marker and showed similar results to TE in CHC patients. However, new cutoff points need to be established to improve its performance on patients with CHC.
Iron overload in chronically HCV-infected patients was uncommon and hepatic iron content seemed not to be related to the liver damage process. In the eventuality of iron overload, histochemical liver iron is a useful marker to estimate HIC.
The chronic course of hepatitis E virus infection in immunosuppressed patients has been recently documented; however, clinical features and factors associated with this occurrence are not well known. The aim of this study was to evaluate the prevalence of previous or current HEV infection in renal transplant patients. One hundred ninety-two kidney transplant patients were studied and classified in three groups: G1-infected with hepatitis B and/or C virus; G2-patients with elevated ALT; G3-patients with normal ALT and no hepatotropic virus infection. Demographic, epidemiologic and clinical characteristics were compared between the groups. Patients with HEV infection (previous or current) were also compared to those who tested negative for HEV. HEV infection was detected using serologic (anti-HEV IgG) and molecular (HEV RNA) methods. Anti-HEV IgG was positive in 28 (15%) while HEV RNA was positive in 20 (10%). When both markers were considered, 44 (23%) patients showed evidence of previous or current HEV infection. However, both markers were concomitantly positive in only four cases (2%). In the comparative analysis, patients infected with HBV and/or HCV showed lower frequency of anti-HEV IgG (P = 0.009). There was no difference regarding demographic, epidemiologic and laboratory variable between viremic and non-viremic patients. In conclusion, past and current infection with HEV was a frequent finding among renal transplant recipients. Actively infected patients (HEV RNA positive) did not present distinct demographic and epidemiological characteristics or laboratory alterations suggestive of underlying liver damage. Therefore, infection with HEV can only be detected in immunosuppressed patients by systematic investigation of HEV RNA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
