Hepatitis B.

The hepatitis B virus is a hepatotropic virus that can produce a variety of clinical syndromes in patients ranging in age from infants to elderly adults. Worldwide, it is among the leading causes of fulminant hepatic failure, cirrhosis, and hepatocellular carcinoma. Recent advances have led to effective antiviral treatments using interferon and nucleoside analogues. Highly effective vaccinations also are used widely and ultimately may lead to eradication of this life-threatening virus.

Successful combined liver-heart transplantation in adults: report of three patients and review of the literature.

BACKGROUND: Three patients received liver/heart transplantation, and we report their successful outcome. METHODS: Two patients had alcoholic cirrhosis and dilated cardiomyopathy; one had cryptogenic liver disease and idiopathic cardiomyopathy. RESULTS: All patients had evidence of portal hypertension and coagulopathy. The cardiac transplants were performed first. Cardiopulmonary bypass was discontinued in favor of venovenous bypass, and liver transplantation was then performed. All patients developed acute tubular necrosis; two required a brief period of hemodialysis. There was only one episode of acute cellular rejection of the liver. Protocol endomyocardial biopsies in all three patients revealed no evidence of rejection. All patients are currently using low doses of immunosuppressive medications and have normal liver chemistry tests and cardiac function; two patients have mild renal insufficiency. CONCLUSION: In selected patients with severe cardiac dysfunction and advanced liver disease, liver/heart transplantation can be successfully performed even in the face of portal hypertension and coagulopathy.

Rapidly progressive liver injury and fatal alcoholic hepatitis occurring after liver transplantation in alcoholic patients.

Alcohol-related liver disease (ALD) is a common indication for orthotopic liver transplantation (OLT) in adults. Although return to 'heavy drinking' post-OLT is believed to be uncommon, the prevalence and severity of alcohol-related liver injury in such patients is not well characterized. We retrospectively reviewed the records of 68 adult patients who underwent OLT for ALD to determine the incidence of return to heavy drinking and to assess their clinical outcome. Follow-up ranged from 8-99 months (mean 42) post-OLT; 54 patients were followed for > or = 12 months. Ten patients (15%) had evidence of coexisting viral hepatitis (hepatitis C in 9 and hepatitis B in 1) before OLT. Six of 68 patients (8%) returned to heavy drinking post-OLT, and three of those died of alcoholic hepatitis at nine months, 2.5 and 3.5 years after OLT. In two of these three patients, premortem liver biopsy showed histologic features of alcoholic hepatitis in addition to bridging fibrosis or cirrhosis. None of the three patients who died of ALD had coexisting viral hepatitis. Of the 57 patients surviving for > or = 3 months post-OLT, 4 of 8 patients (50%) with steatosis and Mallory bodies in their native livers returned to heavy drinking compared to only 2/49 (4%) without these histologic findings (P<0.05). In conclusion, the incidence of heavy drinking post-OLT was uncommon, however, it was associated with fatal alcoholic hepatitis in 50% of patients. Rapidly progressive alcohol-related liver injury was seen even in the absence of coexisting viral hepatitis. The presence of steatosis and Mallory bodies in the native liver, which suggests recent or ongoing alcohol-related liver injury, predicted a return to heavy drinking post-OLT.

Clinical course and management of inflammatory bowel disease after liver transplantation.

BACKGROUND: Previous reports investigating the clinical course and management of inflammatory bowel disease (IBD) after orthotopic liver transplant (OLT) have revealed conflicting results. METHODS: To determine the natural history and course of therapy for liver transplant patients with IBD, we reviewed the records of 35 patients, who underwent OLT between 1985 and 1996 and who had a history of either IBD (29 patients) or primary sclerosing cholangitis (PSC) without evidence of IBD before OLT (6 patients). Of 29 patients with IBD before OLT, 25 had a history of ulcerative colitis (UC) and 4 had Crohn's disease. Six patients had undergone total colectomy, one subtotal colectomy, and three partial colectomy before OLT. Mean follow-up after OLT was 37+/-6.4 months. Immunosuppression included cyclosporine, prednisone, and azathioprine in 34 patients and tacrolimus and prednisone in 1 patient. RESULTS: After OLT, 17 patients (49%) had quiescent disease and were receiving no additional medications other than standard immunosuppression to prevent organ rejection. Five patients (14%) had mild flares controlled with initiation of 5'-aminosalicylates (5'-ASA), and two patients (6%) required an increase in oral prednisone. Only one patient with PSC, without evidence of IBD before OLT, developed IBD after OLT. No patients required intravenous steroids or surgical intervention for active IBD. CONCLUSIONS: (1) Standard postOLT immunosuppressive agents in patients undergoing OLT with IBD were able to adequately control disease activity after OLT in the majority of patients. (2) IBD flares after OLT were generally well controlled with aminosalicylates or oral steroids. (3) Aminosalicylates were helpful in the clinical management of IBD, even when patients were taking standard doses of steroids, azathioprine, and cyclosporine.
