The lived experience of end-stage liver failure and liver transplantation.

This phenomenological study examined the lived experience of an individual who underwent end-stage liver failure and liver transplantation. The participant was asked to respond to the question, what was it like for you having experienced end-stage liver failure and liver transplantation? Permission was granted to tape-record the interview. Themes derived from the data analysis were identified, analyzed, and sorted. As a result, four categories were delineated: (1) uncertainty, (2) control, (3) social support, and (4) spirituality. Categories and themes contributing to a description of one individual's experience with end-stage liver failure and liver transplantation may provide direction for interventional studies designed to effect change in the lived experiences of those undergoing similar phenomena.

Evidence for liver cell proliferation during fatal acute liver failure.

Liver cell regeneration was assessed by determining the mitotic index and the frequency of liver cells with interploid DNA values in livers from patients dying from fulminant hepatitis. For comparison, the same parameters were determined in patients with uncomplicated hepatitis. We found comparable levels of regeneration in the two groups, indicating that the rate of liver cell destruction is a major determinant in the prognosis of acute liver failure. Accordingly, measures to prevent liver cell necrosis seem at least as important as stimulation of regeneration. Judged from available experimental evidence, substances with documented hepatotrophic effect in animals, such as insulin and glucagon, may therefore not be effective in acute liver failure unless the patient has impaired secretion of these substances.

The American experience with transplantation for acute liver failure.

Liver transplantation has become the major therapy for acute liver failure (ALF) in the United States. Survival rates range from 46% to 89%. Appropriate patient selection, timely referral, and management of common complications have improved survival. Donor organ shortage may prompt further use of extracorporeal support systems and auxillary transplantation in the future. This article reviews the American experience of liver transplantation in patients with ALF.

Progression from idiopathic portal hypertension to incomplete septal cirrhosis with liver failure requiring liver transplantation.

We report the case of a 30-year-old male patient suffering from what was initially thought to be end-stage cryptogenic cirrhosis with portal hypertension and liver failure, who underwent liver transplantation. Histological examination of the surgical specimen showed incomplete septal cirrhosis. At the age of 17 this patient had presented pancytopenia and splenomegaly, which were treated by splenectomy. The surgeon discovered portal hypertension. Re-examination of the wedge liver biopsy taken at this time revealed features of idiopathic portal hypertension. This case clearly shows that incomplete septal cirrhosis may be a late manifestation of idiopathic portal hypertension. The presence of sinusoidal dilatation and peliosis as well as early evidence of fibrosis which are already visible on the initial biopsy and are still present on the late specimen, are indirect evidence of a continuous process which ultimately led to incomplete cirrhosis with liver failure.

Liver failure.

Liver failure is a complication of viral hepatitis, as well as a consequence of acute mushroom or drug poisoning. The different therapies to be employed in a "pre emergency" state, or in case of "emergency" (resistant to medical treatment or starting as "fulminant" hepatic failure) are summarized. The percentage of survival, even by means of sophisticated treatment, does not overcome 30%.

A predictive model for the development of hepatocellular carcinoma, liver failure, or liver transplantation for patients presenting to clinic with chronic hepatitis C.

OBJECTIVE: Chronic infection with hepatitis C may lead to the development of cirrhosis, liver failure, and hepatocellular carcinoma. However, not all patients progress to these endpoints. Ideally, clinicians could improve their capability of stratifying the risk and the time frame within which their patients will progress to these endpoints. The purpose of the present study was to construct statistical models predicting disease progression for individual patients. METHODS: Study endpoints were the development of hepatocellular carcinoma, liver transplantation, or death due to liver disease. The study cohort was 256 patients with hepatitis C acquired from either blood transfusion or use of intravenous drugs. During follow-up, 17 patients developed hepatocellular carcinoma, seven received liver transplantation, and 12 died from liver disease. RESULTS: On multivariate analysis a history of decompensation (relative risk [RR] 4.321, 95% confidence interval [CI] 1.777-10.511) and the serum albumin (RR 0.253, 95% CI 0.136-0.474) were independently associated with the study endpoints. Patients without a history of decompensation and with a serum albumin > or = 4.1 mg/dl had a 3.2% chance of developing the study endpoints within 5 yr. Patients with a history of decompensation and a serum albumin < 4.1 mg/dl had a 40% chance of developing a study endpoint within 5 yr. Baseline genotype and quantitative RNA were not associated with development of the clinical endpoints, with the exception of patients coinfected with two or more genotypes. CONCLUSION: Thus, the serum albumin and a history of decompensation are useful for predicting the development of hepatocellular carcinoma, liver transplantation, and death due to liver disease among patients with hepatitis C.

Hepatitis A-induced diabetes mellitus, acute renal failure, and liver failure.

A 38-year-old otherwise healthy man presented with hepatic failure (aspartate aminotransferase of 7212 U/L, alanine aminotransferase of 6629 U/L, total and direct bilirubin of 10.7 mg/dL) and acute renal failure (creatinine of 11.6 mg/dL and blood urea nitrogen of 42 mg/dL), which required hemodialysis when the creatinine increased to 21 mg/dL, with a blood urea nitrogen of 115 mg/dL, and the patient became oliguric. On admission, this patient also had a lipase of 1833 U/L, amylase of 211 U/L, glucose of 210 mg/dL, and reactive IgM antibody for acute hepatitis A. The hepatitis and acute renal failure resolved in 3 months, but this patient continues to have type II diabetes mellitus 7 years after the hepatitis A infection. This case illustrates that hepatitis A infection may be severe with liver failure, acute renal failure, and permanent diabetes mellitus as sequale of this infection.

[Orthotopic liver transplantation in Wilson's disease and acute liver failure].

Liver histology demonstrated progressive cirrhosis in a 19-year-old girl with a subacute form of Wilson's disease. Despite D-penicillamine administration her liver functions rapidly deteriorated further. Orthotopic liver transplantation was performed. Postoperatively there were two mild rejection episodes, an organic psychiatric syndrome and generalized tremor. Copper metabolism and clinical symptoms became normal postoperatively. Five months after the transplantation she was in a good general condition, able to continue her education.

Liver biopsy and prognosis in acute liver failure.

Liver biopsy was performed in 38 patients with fulminant hepatitis and coma and repeated in 22. Stereological estimation of hepatocyte volume was correlated with levels of clotting factors. Early liver biopsy allowed prognosis in 55% of the cases. All patients with a hepatocyte volume of <35% and thromboplastin time </=10% died; all patients but two with hepatocyte volume >/=35% and thromboplastin time >10% recovered consciousness (n = 9) or at least showed evidence of marked liver regeneration (n = 2). On serial liver biopsy a significant increase in hepatocyte volume and clotting factors was only observed in patients who recovered consciousness. The estimated liver cell mass after regeneration in patients who recovered consciousness was >/=45% and <45% in the patients who did not.

Extracellular brain glutamate during acute liver failure and during acute hyperammonemia simulating acute liver failure: an experimental study based on in vivo brain dialysis.

Hyperammonemia is thought to be important in the pathogenesis of hepatic encephalopathy. However, the mechanism leading to ammonia toxicity is still not known. Since the metabolism of the most important excitatory neurotransmitter, glutamate, is closely linked to that of ammonia, it has been postulated that hyperammonemia lowers the availability of the neurotransmitter glutamate. To study this hypothesis, we used brain dialysis to measure glutamate levels in extracellular cerebral fluid from rabbits with acute ischemic liver failure or acute hyperammonemia. The basal glutamate concentration was found to be increased during both acute liver failure (start of experiments 4.9 +/- 1.7 mumol/l; end of experiments 9.5 +/- 2.1 mumol/l, n = 6, difference p < 0.05) and acute hyperammonemia (start of experiments 4.4 +/- 1.2 mumol/l; end of experiments 7.3 +/- 1.8 mumol/l, n = 7, difference p > 0.05) (mean +/- SEM). Both the veratridine- and the potassium-evoked glutamate release were increased during acute liver failure but appeared normal during hyperammonemia. We conclude that during acute liver failure and acute hyperammonemia in the rabbit there is no decreased glutamate availability in the extracellular space of the cortical brain; on the contrary, we found evidence for increased extracellular glutamate concentrations in the cortical brain, which were more pronounced in acute liver failure. Experimental hepatic encephalopathy is thus not due to cerebral glutamate deficiency.

Management of acute liver failure.

Acute liver failure (ALF) constitutes a medical emergency requiring the prompt response of experienced clinicians. As it is relatively infrequent, and tends to evolve rapidly, decisions concerning care and prognosis must be made promptly. Determining etiology is vital since prognosis is largely determined by the cause of the illness, and the use of antidotes may be lifesaving. Estimating the severity of the liver failure is also important, because if liver transplantation is necessary, it must be undertaken quickly. No treatment thus far is better than good general care of the comatose patient, with attention to the special problems associated with acute liver failure: cerebral edema, infection, circulatory collapse. A number of issues have been debated recently, including use of prostaglandins and N-acetylcysteine for treatment of all forms of acute liver failure, and the use of extracorporeal liver assist machines, however, the efficacy of non-specific treatments for this complex syndrome has not been proven.

[Prognostic factors in acute liver failure].

Acute liver failure is defined as acute severe, potentially reversible hepatic failure complicated by cerebral dysfunction. The high mortality rate of between 50% and 90% justifies early transfer to a specialised centre with the possibility of orthotopic liver transplantation to ensure adequate intensive care monitoring and treatment, 57 patients with acute liver failure (34 female, 23 male, aged 6 to 87 years, median 33 years) treated at our intensive care unit during the past 10 years were analysed retrospectively. Various factors and laboratory data were analysed in respect to their prognostic value. Depending on the aetiology, the survival rate in acute liver failure under conservative treatment ranges from 79% (amanita intoxication) to 10% (cryptogenic genesis). The most important predictive parameter is the extent of cerebral dysfunction. The extent of cerebral dysfunction is a determining factor of the survival rate under conservative treatment; it ranges from 94% (patients with hepatic encephalopathy grade I) to 11% (patients with hepatic encephalopathy grade IV). The occurrence of complications such as infections, cerebral oedema, respiratory failure or renal failure is also associated with an unfavourable outcome. Additionally, various laboratory parameters have a predictive ability. The mortality rate of our patients with acute liver failure has decreased from 56% to 32% since early intensive care monitoring and treatment and the possibility of acute orthotopic liver transplantation were established.

Acute liver failure.

Acute liver failure is a multiorgan syndrome with dramatic clinical features and, often, a fatal outcome. It is characterized by the onset of coma and coagulopathy within 6 months, and usually in < 6 weeks, from onset of illness. Viral hepatitis, drug-related liver injury, and the alcohol-acetaminophen syndrome are the most common etiologies. Altered mental status accompanied by jaundice is a hallmark of acute liver failure. A unique feature is the evolution of increased intracranial pressure due to cerebral edema. The resulting cerebral ischemia and brainstem herniation account for approximately 50% of deaths in patients with acute liver failure. Mannitol therapy may successfully treat most patients with high intracerebral pressure. Most patients demonstrate features of the multiple organ failure syndrome, including a shock-like state, renal failure, and occasionally respiratory distress syndrome. Close monitoring of volume status is necessary, since administration of large quantities of fluid may be required. Infection is also common; most pathogens are gram-positive, and fungal infections are also seen. Because an optimum therapy for acute liver failure does not yet exist, liver transplantation should be considered early, before advanced levels of coma develop. Alternative, experimental treatment modalities include heterotopic liver grafting, administration of hepatocyte growth factor, use of an extracorporeal liver-assist device, and liver cell transplantation, but none of these has attained widespread use.
