[59] The risk of death from acute liver failure following HAV infection increases with age and when the person has underlying ...
The Internal Autoimmune Hepatitis Group developed a standardized scoring system for clinical diagnosis in population studies but lacks value in individualized cases. [17] A simplified scoring system for clinical use incorporates titers of autoantibodies, total IgG levels, liver histology, and the exclusion of viral hepatitis for diagnostic scoring.

Hepatitis C virus (HCV) can cause acute and chronic infections that are a major cause of hepatocellular carcinoma (HCC), advanced hepatic fibrosis and cirrhosis. [citation needed] HCC is a major cause of death in patients with chronic HCV infection. Regarding the pathogenesis of HCC associated with HCV, that virus may play direct or indirect roles.
Hyper IgM syndrome is a rare primary immune deficiency disorders characterized by low or absent levels of serum IgG, IgA, IgE and normal or increased levels of serum IgM. [ 8 ] They are resulting from mutations in the pathway from B-cell activation to isotype class switching.
Hyper IgM syndrome can have the following syndromes: [6] [11] Infection/Pneumocystis pneumonia (PCP), which is common in infants with hyper IgM syndrome, is a serious illness. [9] PCP is one of the most frequent and severe opportunistic infections in people with weakened immune systems. Hepatitis (hepatitis C) Chronic diarrhea; Hypothyroidism ...
Hepatorenal syndrome is a particular and common type of kidney failure that affects individuals with liver cirrhosis or, less commonly, with fulminant liver failure. [1] The syndrome involves constriction of the blood vessels of the kidneys and dilation of blood vessels in the splanchnic circulation, which supplies the intestines. [2]
