Acute renal failure (ARF) is a frequent medical complication after liver transplantation (LT). We analyzed cadaveric related liver transplant recipients who had developed ARF early in the postoperative course. Between January 1982 and August 2003, a total of 67 patients underwent cadaveric related LT. Their mean age was 28.64 years at LT. The 67 recipients had the following indications: biliary atresia (n = 17), Wilson's disease (n = 15), hepatitis B-related liver cirrhosis (n = 14), hepatitis C-related liver cirrhosis (n = 4), primary biliary cirrhosis (n = 4), hepatitis B-related liver cirrhosis with hepatoma (n = 3), hepatitis C-related liver cirrhosis with hepatoma (n = 2), Budd-Chiari syndrome (n = 2), neonatal hepatitis (n = 1), choledochus cyst (n = 1), autoimmune cirrhosis (n = 1), neuroendocrine tumor (n = 1), and hemangioendothelioma (n = 1). Forty-nine patients received cyclosporine (CsA), azathioprine, and steroids and 18, a combination with tacrolimus (FK506). Eight (11.94%) patients developed ARF at a mean time of 17.25 days after LT. The mean peak serum creatinine was 2.24 mg%. Four of these patients had a diagnosis of hepatitis B-related liver cirrhosis; two, hepatitis C-related liver cirrhosis; one, primary biliary cirrhosis; and one, hepatitis B-related liver cirrhosis with hepatoma. The ARF etiology was multifactorial for the majority of patients. Eight ARF patients had a history of liver cirrhosis, which may be a risk factor for intraoperative ARF. ARF treatment included fluid replacement, decreased or altered immunosuppressive agents, avoiding exposure to nephrotoxic drugs, and adjusting antibiotic dosages. The majority of patients returned to normal renal function at 1 to 3 weeks after the diagnosis of ARF. No patient required dialysis and/or experienced a mortality. We conclude that the incidence of ARF is relatively low and with good outcomes. ARF etiology was multifactorial for the majority of patients, but eight patients had a history of liver cirrhosis, which may be a risk factor for intraoperative ARF. We suggest that in the early postoperative period of LT cases diagnosis and treatment of ARF are important.

As the prevalence of chronic liver disease and chronic kidney disease (CKD) increase, clinicians are likely to be increasingly faced with difficult diagnostic, treatment, and ethical challenges when facing both of these diseases in a single patient. Alterations in creatinine formation and elimination in cirrhotic patients render creatinine-based estimates of glomerular filtration rate and dialysis adequacy less accurate in this population. Furthermore, differentiating signs and symptoms of uremia from hepatic disease may be difficult and clear indications for renal replacement therapy (RRT) in these patients have not been defined. Hemodialysis is associated with a high rate of complications and has not been shown to prolong life in cirrhotic patients with acute renal failure (ARF), but has not been carefully examined in those with CKD. Peritoneal dialysis is, similarly, unhelpful in chronic liver disease complicated by ARF, but has been found to be a viable option in some cirrhotic patients with CKD. Continuous RRT is generally tolerated by patients with decompensated cirrhosis and either acute or chronic renal failure and may act to bridge patients to liver transplantation. Given the poor underlying survival of cirrhotic patients with renal failure, clinicians should carefully consider the utility of RRT in each patient.

Liver cirrhosis is an escalating health problem attributed to numerous causes, including an increase in alcohol consumption, morbid obesity and chronic viral hepatitis. The circulatory disturbances seen in advanced cirrhosis lead to the development of ascites, which often lead to progressive renal impairment or the development of hepatorenal syndrome. Furthermore, cirrhotic patients commonly experience clinical situations that predispose them to the development of pre-renal failure, such as dehydration, hypovolaemia, septic shock, or exposure to nephrotoxic drugs. This article provides an overview of the main causes of acute renal failure in liver cirrhosis and describes the current medical and nursing management.

Branched-chain amino acids (BCAA: leucine, isoleucine and valine) are not just structural constituents of proteins, but have ''pharmacologic'' properties, known for several years: BCAA are catabolized mainly in muscle; can be oxidized with energy production, being nitrogen donors for other amino acids; regulate protein synthesis and degradation; modulate metabolism of neuroactive mediators. These properties make the clinical use of BCAA particularly suitable in critical conditions such as liver cirrhosis, sepsis, surgical or nonsurgical trauma, acute renal failure, acute pancreatitis, cancer, in which energy production from conventional substrates is altered and, at the same time, reduction of protein catabolism and enhancement of synthetic processes is advisable. Recently, the changes of plasma aminoacidograms induced by the administration of high-dose BCAA in sepsis have been better detailed: 1) a tendency to normalization of high levels of proline and of other amino acids transported intracellularly by transport system ''A''; 2) less relevant reduction of the levels of other amino acids; 3) increase of the levels of taurine, glutamate and aspartate; more complex interactions with specific amino acids. These changes, and changes of other variables, reconfirm in part some well-known properties of BCAA, and are also objective indicators of an improvement of the metabolic abnormalities of sepsis induced by BCAA administration. In sepsis and in other stress conditions it is recommended to administer, within balanced parenteral nutritional regimens, AA solutions with a 35-50% BCAA concentration.

Epstein-Barr virus (EBV) infection can cause diverse renal manifestations ranging from microscopic hematuria to acute renal failure. Membranous nephropathy (MN) is an uncommon and usually secondary cause of nephrotic syndrome in children, and has been reported after chronic infections and antigenemia. We report two pediatric cases of secondary MN associated with acute and chronic systemic EBV infection. Patient 1 had a liver transplant for cirrhosis due to biliary atresia and developed chronic EB viremia. Membranous nephropathy occurred 3 years later and with aggressive therapy has partially subsided, in temporal association with a drop in blood EBV PCR levels. The other patient had a primary immunodeficiency and developed a lymphoproliferative disorder attributed to EBV. Nephrotic syndrome developed at initial presentation and was associated with MN on biopsy. The patient cleared the virus from blood, which was associated with eventual resolution of the MN. We postulate that EB viremia in patients lacking a fully competent immune system, but without a renal allograft, may create a susceptible environment for chronic systemic EB antigenemia that can then lead to immune-complex MN in the kidney. The association of EBV with renal histological changes consistent with MN has been suggested but not directly described before.

Antithymocyte globulin (ATG) has been shown to be effective as a pretreatment immunosuppressive agent in liver transplantation because of the ability to wean tacrolimus monotherapy after 4 months in pretreated recipients. However, the use of ATG can be complicated by serious side effects. Reported side effects include severe cardiopulmonary reactions, adult respiratory distress syndrome and hematological disorders. We report a case of a patient with a medical history of cirrhosis scheduled for orthotopic liver transplantation that, during the operation, showed swelling, hyperthermia, tachycardia and hypotension after the administration of ATG. Acute renal failure (ARF) was another serious side effect that our patient developed during ICU stay; we ascribed the occurrence of ARF to the serum sickness disease triggered by the ATG administration. Only one case has been reported of ARF after ATG-therapy before our experience. Therefore, severe hyperthermia and signs of cardiovascular dysfunction early after the beginning of ATG administration should be carefully evaluated and may need to consider the immediate ATG therapy withdrawal to prevent ARF.

Spontaneous bacterial peritonitis (SBP) is an acute bacterial infection usually associated with ascites and cirrhosis or is a complication of peritoneal dialysis. There are very few case reports of cancer patients who developed this disease. Furthermore, there have been no published case reports of successfully treated gynecological cancer patients who later developed SBP. We present a case involving a 41-year-old woman who was treated for cervical carcinoma in 1992. She underwent radical surgery and adjuvant chemoradiation therapy. Two years later, the patient presented with streptococcal group B cellulitis associated with left leg lymphedema. She recovered following antibiotic treatment but had recurrent episodes of streptococcal cellulitis in her leg over the past 10 years. In 2003, the patient was admitted to the hospital because of sepsis, acute renal failure, and SBP. She was treated and recovered following treatment. SBP is usually associated with cirrhosis. Although SBP is rarely seen in successfully treated gynecological cancer patients, oncologists should be aware of this clinical entity. Timely treatment is essential to maximize chances of survival.

Hepatorenal syndrome is a functional renal failure in patients with advanced cirrhosis and portal hypertension or acute liver failure. It is caused by extreme vasoconstriction in renal arterial bed. Type I HRS presents as an acute renal failure, while type II HRS is chronic alteration of renal function in patients with refractory ascites. Prognosis of HRS is very poor with survival reaching several weeks in patients with HRS type I. Causal treatment is liver transplantation, other treatment options include use of splanchnic vasoconstrictors (terlipressin) together with plasmaexpansion (albumin) and TIPS. It is important to exclude nephrotoxic medication (non-steroid anti inflammatory drugs, aminoglycosides) and properly treat all infective complications in prevention of HRS.

We report the case of a Child class C cirrhotic patient who was diagnosed with coronary artery disease in the course of his pretransplantation evaluation. He underwent off-pump coronary artery bypass grafting (OPCAB), which was complicated with acute renal failure. The morbidity and mortality associated with cardiac operation in patients with cirrhosis is discussed, and the potential advantage of OPCAB in this patient population is emphasized.

With the wider use of imaging and interventional techniques that require the use of iodinated contrast media in seriously ill patients, many clinical situations occur where patients may be at increased risk for contrast-induced nephropathy (CIN). There is little guidance for clinicians in these areas. The aim of this review is to assess the available literature. Acute renal failure is a common complication following coronary artery bypass surgery, and exposure to contrast medium may increase the risk for this condition, although there is insufficient evidence to make a definitive statement. Evidence is also limited for patients with liver disease: in those undergoing transarterial chemoembolization, cirrhosis may be a risk factor for renal failure. There is some evidence that periprocedural hypotension may be a risk factor for CIN after percutaneous coronary intervention, but no published information was identified on the significance of shock or hypotension in other groups of patients. The published evidence on the risk of CIN in renal transplant recipients is inconsistent. In emergency situations, the course of action is usually dictated by clinical circumstances; the renal status of a patient is likely to be unknown and it is important to ensure adequate volume expansion, especially after the procedure. In all clinical situations that are potentially associated with a high risk for CIN, the decision to administer contrast medium is a matter for clinical judgment, based on the clinical status of the patient and the expected benefits of the investigation or procedure.
