ABSTRACT Despite strong evidence suggestive of associations between hepatic and pancreas , a potential relationship between acute this review article are: hepatitis failure represents the highest incident rate of hepatitis-related acute ; so a hepatitis and has not been a matter of review; which we focused on in the current paper. Some of the main findings of reported mortality; and a male preponderance in the incidence, with females developing in older ages and having shown the signs of both program might be indicative in these patients. Specific characteristics of HAV- related pancreatitis are that it is a benign condition with no- ed acute pancreatitis was most likely to represent and there was an apparent ethnic-priority with Indian descents, the only conditions simultaneously. The incidence of acute pancreatitis in HBV is the lowest, but the mortality was the highest. HEV-relat and in IFN-induced pancreatitis, cessation of the drug was most effective in treatment, with no catastrophic event reported. reported cases in the literature. Hepatitis-related pancreatitis in liver transplant recipients was most frequent in HBV infected patients;

A similar study by Ede [11] on 35 FHF patients ( overdose (27 cases), studies, the existing data is suggestive of a benign course non-A non-B hepatitis (4), hepatitis B (3) and hepatitis A of AP in HAV patients.

Overall, The lower percentage of patients diagnosed with AP in AP due to FHF seems to have a high incidence; but due to number of reports in the literature; with the least number patients.the high associated with this condition [13], to infection by other hepatitis almost reflects the no judgment can be made on the fatality of AP in FHF HEPATITIS A VIRUS ofYuen reports et al. for such a relation for HBV infection.
