Quality of life and psychiatric complications after adult living donor liver transplantation.

We investigated the psychosocial effects of a right hepatectomy on donors for adult living donor liver transplantation (ALDLT). Questionnaires were sent to 66 actual donors, who had undergone ALDLT between August 1998 and September 2003, as well as to 139 potential donors, who had been examined as possible candidates for ALDLT; the latter had been excluded and had not undergone surgery. All actual donors reported full recovery within an average period of 14.41 (standard deviation = 8.86) weeks; all had returned to their preoperative employment. In preparation for ALDLT, they had received significantly more support from their families in the decision-making process than the potential donors had (t = 2.02; degree of freedom = 79; P = 0.047); they also felt better informed about donation than the potential donors (t = 2.04; df = 64; P = 0.045). Psychiatric problems occurred in 6 (14%) female donors in the perioperative period, mostly in connection with unrealistic outcome expectations. Donors with severe postoperative complications (n = 3) demonstrated higher scores of psychiatric symptoms (chi-square = 6.39; df = 2; P = 0.041). When we compared potential and actual donors, a significant difference in emotional quality of life was not demonstrated (t = 0.41; df = 76; P = 0.684), and it corresponded to that of the normative sample. For donors, perceived emotional quality of life did not depend on the course of recovery of the recipients. Six to 9 months after donation, potential donors reported a significantly higher physical quality of life than actual donors (t = 2.20; df = 56; P = 0.032). In conclusion, female donors, donors with their own major complications, or donors with unrealistic outcome expectations should be provided with adequate psychosocial care. With regard to the psychosocial outcome, ALDLT is a safe intervention for the donor.

Non-alcoholic fatty liver disease in HIV-positive patients predisposes for acute-on-chronic liver failure: two cases.

Non-alcoholic fatty liver disease is a prominent feature in HIV-positive patients. We present two patients with long-lasting HIV-infection who suffered from this disease, as induced by highly active anti-retroviral therapy (HAART). The patients developed acute-on-chronic (AOC) liver failure after either (case 1) acute infection with hepatitis A virus (HAV) or (case 2) methamphetamine abuse ('Ecstasy'). Approximately 1 week after visiting an area endemic for HAV, case 1, a male patient, presented with icterus, elevated liver transaminases and HAV IgM. Previous examinations had demonstrated normal liver transaminase activities while hepatic steatosis had been suspected. He developed complications associated with liver failure including renal failure as well as pleural and pericardial effusions. Case 2, a second male patient, developed both liver failure and lactic acidosis 24 h after methamphetamine abuse. Both patients suffered from fatty liver in the pre-acute stage as indicated by ultrasound examination. After developing symptoms of liver failure, HAART was discontinued in both patients. Follow-up visits demonstrated that the patients recovered clinically with almost normalized laboratory parameters. In HIV infection, HAART-induced hepatopathological alterations may exist despite the absence of relevant laboratory parameters. These patients are likely to develop AOC liver failure when subjected to acute risk factors such as hepatitis viruses and narcotics or other drugs. In patients treated with HAART, we thus highly recommend hepatitis A and B virus vaccinations, and close monitoring of liver parameters.

Antiviral treatment of chronic hepatitis B with lamivudine in pediatric renal transplantation.

Renal transplantation in patients with chronic hepatitis B virus (HBV) infection is known to be associated with an increased risk for exacerbation of liver dysfunction. Lamivudine has been proven to be a potent inhibitor of hepatitis B virus replication in adults after kidney transplantation. Little is known about its efficacy and safety in pediatric renal transplant recipients. Three cases serve for the discussion to demonstrate the complexity of the clinical course and effective treatment of chronic hepatitis B in pediatric patients awaiting renal transplantation. Two patients on dialysis with a high HBV replication rate were treated with lamivudine before transplantation. After the viral load had decreased below the detection limit, they underwent transplantation successfully. Despite intensified immunosuppression to treat a rejection episode in one and a relapse of the nephrotic syndrome in the other patient, the viral load remained <2.5 pg/mL. Both patients developed a mutation in the YMDD motif of the HBV genome associated with an increase in the HBV replication rate >10,000 pg/mL without deterioration of the liver function. In a third patient with a chronic HBV infection with a low replication rate, lamivudine was started about nine months after kidney transplantation due to an increasing viral load after treatment of an acute rejection episode. Six months later, the HBV DNA was no longer detectable. The patient had no signs of liver dysfunction. Lamivudine in the treatment of chronic HBV infection in pediatric renal recipients seems to be safe and effective in preventing acute liver deterioration. Three clinical cases are discussed with regard to current options in monitoring and antiviral treatment of chronic HBV in pediatric renal transplant recipients.

[Manualised group therapy concept for patients with alcoholic cirrhosis awaiting liver transplantation].

OBJECTIVES: Patient compliance after transplantation is of key importance since even moderate deviations from the prescribed therapy regime may cause organ rejection. Patients with alcoholic liver cirrhosis require special therapeutic preparation before the liver transplantation. METHODS: A manualised group therapy with the aim of maintaining alcohol abstinence, increasing coping skills and therapy adherence is presented and illustrated with a case history. The manual is based on the elements of psychoeducation and problem-solving training. In a second article the results of the clinical evaluation are described.

[Stabilisation of abstinence by means of psychoeducation for patients with alcoholic liver disease awaiting liver transplantation].

BACKGROUND: A manualised six-month psychoeducational intervention was conducted in patients with alcoholic liver disease and abstinence problems who were waiting for a transplantation. OBJECTIVES: In a naturalistic design it was investigated whether the intervention could improve patients' alcohol abstinence. METHODS: Between January 2002 and November 2003, 72 patients were enrolled in the therapeutic intervention, 48 of whom participated in group therapy. Health-related quality of life (SF-12), anxiety and depression (HADS-D), symptom strain (BSI) and social support (F-SOZU) were measured. Alcohol abstinence was examined in each group session by measuring the alcohol concentration in breath. RESULTS: At the beginning and end of the group therapy patients showed subsyndromal measures of anxiety and depression and minor symptoms of psychopathology. Physical quality of life was reduced (t = -8.694; df = 44; p < .001). Mental quality of life was in the range of the normative sample and was correlated with depression (r = -0.400; p = .009). Patients perceived high social support (t = 8.213; df = 45; p < .001). During the course of therapy four patients had relapses but the remaining patients stayed abstinent. Physical quality of life improved (t = -2.275; df = 27; p = .031), mental quality of life and symptom strain remained stable. CONCLUSIONS: The therapy presented here facilitated a stabilisation of mental well-being in patients with alcoholic liver disease who were waiting for organ transplantation. The relapse rate measured by alcohol concentration in breath remained low.

Cyclosporine A, FK-506, 40-0-[2-hydroxyethyl]rapamycin and mycophenolate mofetil inhibit proliferation of human intrahepatic biliary epithelial cells in vitro.

AIM: To investigate the effect of cyclosporine A (CsA), FK-506, and mycophenolate mofetil (MMF) and 40-0-[2-hydroxyethyl]rapamycin (RAD) on proliferation of human intrahepatic biliary epithelial cells (BECs) in vitro. METHODS: BECs were isolated from six human liver tissuespecimens with the immunomagnetic separation method and treated with different concentrations of CsA, FK-506, RAD, and MMF in vitro. Proliferation of the cells was measured by MTT assay at 24 and 48 h after treatment, respectively. One-way analysis of variance was used to analyze the results. Expression of CK 19 in BECs was monitored by flow cytometry and Western blot. RESULTS: Six lines of BECs were established. They survived for 4-18 wk in vitro. Flow cytometry analysis showed that these cells always expressed CK19. CsA, FK-506, RAD, and MMF inhibited proliferation of BECs in a dose-dependent manner. The lowest concentration of CsA, FK-506, RAD, and MMF to inhibit proliferation of BECs (P<0.05) was 500, 100, 0.25, and 100 mug/L, respectively. However, the expression of CK19 by BECs was not changed. CONCLUSION: CsA, FK-506, RAD, and MMF have an antiproliferative effect on human intrahepatic BECs in vitro, while RAD has the strongest growth-inhibitory effect. Their possible effects on liver regeneration and bile duct injury in transplant patients should be further investigated.

Dark-lumen magnetic resonance colonography in patients with suspected sigmoid diverticulitis: a feasibility study.

To assess dark-lumen magnetic resonance colonography (MRC) for the evaluation of patients with suspected sigmoid diverticulitis. Forty patients with suspected sigmoid diverticulitis underwent MRC within 72 h prior to conventional colonoscopy (CC). A three-dimensional T1-weighted volumetric interpolated breath-hold examination sequence was acquired after an aqueous enema and intravenous administration of gadolinium-based contrast agents. All MRC data were evaluated by two radiologists. Based on wall thickness and focal uptake of contrast material and pericolic reaction including mesenteric infiltration on T1-weighted sequence the sigmoid colon was assessed for the presence of diverticulitis. MRC classified 17 of the 40 patients as normal with regard to sigmoid diverticulitis. However, CC confirmed the presence of light inflammatory signs in four patients which were missed in MRC. MRC correctly identified wall thickness and contrast uptake of the sigmoid colon in the other 23 patients. In three of these patients false-positive findings were observed, and MRC classified the inflammation of the sigmoid colon as diverticulitis whereas CC and histopathology confirmed invasive carcinoma. MRC detected additionally relevant pathologies of the entire colon and could be performed in cases where CC was incomplete. MRC may be considered a promising alternative to CC for the detection of sigmoid diverticulitis.

Diagnosis of biliary strictures after liver transplantation: which is the best tool?

AIM: To evaluate the diagnostic value of different indirect methods like biochemical parameters, ultrasound (US) analysis, CT-scan and MRI/MRCP in comparison with endoscopic retrograde cholangiography (ERC), for diagnosis of biliary complications after liver transplantation. METHODS: In 75 patients after liver transplantation, who received ERC due to suspected biliary complications, the result of the cholangiography was compared to the results of indirect imaging methods performed prior to ERC. The cholangiography showed no biliary stenosis (NoST) in 25 patients, AST in 27 and ITBL in 23 patients. RESULTS: Biliary congestion as a result of AST was detected with a sensitivity of 68.4% in US analysis (specificity 91%), of 71% in MRI (specificity 25%) and of 40% in CT (specificity 57.1%). In ITBL, biliary congestion was detected with a sensitivity of 58.8% in the US, 88.9% in MRI and of 83.3% in CT. However, as anastomotic or ischemic stenoses were the underlying cause of biliary congestion, the sensitivity of detection was very low. In MRI detected the dominant stenosis at a correct localization in 22% and CT in 10%, while US failed completely. The biochemical parameters, showed no significant difference in bilirubin (median 5.7; 4,1; 2.5 mg/dL), alkaline phosphatase (median 360; 339; 527 U/L) or gamma glutamyl transferase (median 277; 220; 239 U/L) levels between NoST, AST and ITBL. CONCLUSION: Our data confirm that indirect imaging methods to date cannot replace direct cholangiography for diagnosis of post transplant biliary stenoses. However MRI may have the potential to complement or precede imaging by cholangiography. Optimized MRCP-processing might further improve the diagnostic impact of this method.

Liver cirrhosis as a consequence of iron overload caused by hereditary nonspherocytic hemolytic anemia.

Nonspherocytic hereditary anemias are occasionally accompanied by significant iron overload but the significance for the development of chronic liver disease is not clear. We described two cases of patients with chronic liver disease and severe iron overload due to chronic hereditary hemolysis. Both patients have had signs of liver cirrhosis and severe hemolysis since childhood. A hereditary pyruvate kinase deficiency (PKD) was discovered as the underlying reason for the hemolysis. Sequencing of the pyruvate kinase gene showed a mutation within exon 11. Liver histology in both patients revealed cirrhosis and a severe iron overload but primary hemochromatosis was excluded by HFE-gene analysis. An iron reduction therapy with desferrioxamine led to significant decrease of serum ferritin and sustained clinical improvement. PKD-induced hemolysis may cause severe iron overload even in the absence of HFE-genotype abnormalities. This secondary iron overload can lead to chronic liver disease and cirrhosis. Therefore, the iron metabolism of PKD patients has to be closely monitored and iron overload should be consequently treated.

Detection of circulating autoantibodies directed against the asialoglycoprotein receptor using recombinant receptor subunit H1.

BACKGROUND/AIMS: The asialoglycoprotein-receptor (ASGPR) is a major liver-specific target autoantigen in autoimmune hepatitis. ASGPR heteromers of two subunits H1 and H2 provide clearance of circulating asialoglycoproteins by receptor-mediated endocytosis. The aim of this study was to establish whether a recombinantly expressed subunit H1 presenting conformational epitopes is capable of detecting autoantibodies against ASGPR in patients with inflammatory liver disease. METHODS: The major subunit H1 was expressed in human-embryo-kidney 293-cells and prepared by ligand-affinity-chromatography similar to the complete receptor from normal liver. Reactivities of anti-ASGPR positive sera from 219 patients with both recombinant H1 and natural receptor were compared using enzyme-immunoassay (EIA). RESULTS: 194 of 219 sera (88.6%) showed absorbance values on 293-H1 within a range of +/-15% compared to the natural receptor. 145 of 149 sera (97.3%) positive on ASGPR were also positive on recombinant H1. Titers of 61/62 sera (98.4%) revealed no deviation of more than one dilution step. ASGPR reactivity could be inhibited in 29 sera with up to 50 ng/microl of 293-H1. CONCLUSIONS: These results indicate that the antigenic sites of the human ASGPR are mainly located on the mammalian-expressed subunit H1. Therefore, 293-H1 is a powerful tool for the detection of autoantibodies against ASGPR.

Small bowel hydro-MR imaging for optimized ileocecal distension in Crohn's disease: should an additional rectal enema filling be performed?

PURPOSE: To assess the impact of an additional rectal enema filling in small bowel hydro-MRI in patients with Crohn's disease. MATERIALS AND METHODS: A total of 40 patients with known Crohn's disease were analyzed retrospectively: 20 patients only ingested an oral contrast agent (group A), the other 20 subjects obtained an additional rectal water enema (group B). For small bowel distension, a solution containing 0.2% locust bean gum (LBG) and 2.5% mannitol was used. In all patients, a breathhold contrast-enhanced T1w three-dimensional volumetric interpolated breathhold examination (VIBE) sequence was acquired. Comparative analysis was based on image quality and bowel distension as well as signal-to-noise ratio (SNR) measurements. MR findings were compared with those of conventional colonoscopy, as available (N = 25). RESULTS: The terminal ileum and rectum showed a significantly higher distension following the rectal administration of water. Furthermore, fewer artifacts were seen within group B. This resulted in a higher reader confidence for the diagnosis of bowel disease, not only in the colon, but also in the ileocecal region. Diagnostic accuracy in diagnosing inflammation of the terminal ileum was 100% in group B; in the nonenema group there were three false-negative diagnoses of terminal ileitis. CONCLUSION: Our data show that the additional administration of a rectal enema is useful in small bowel MRI for the visualization of the terminal ileum. The additional time needed for the enema administration was minimal, and small and large bowel pathologies could be diagnosed with high accuracy. Thus, we suggest that a rectal enema in small bowel MR imaging be considered.

Preoperative donor liver biopsy for adult living donor liver transplantation: risks and benefits.

The role of liver biopsy (LB) in donor selection for adult living donor liver transplantation remains controversial, since the procedure is associated with additional potential risks for the donor. From April 1998 to August 2004, 730 potential living donors for 337 adult recipients underwent our multistep evaluation program. In 144 candidates, LB was performed. LB was obtained in a percutaneous ultrasound-guided fashion by means of Menghini needle (32 cases) or Tru-cut needle (112 cases). The biopsy specimen was preserved in 5% formalin and processed with hematoxylin & eosin-stained sections. Thirty-one (21%) of 144 candidates who underwent an LB had a positive finding at histological examination that induced their exclusion from donation, of whom 21 had liver steatosis of varying kind and grade (10%-80%) and 10 had a nonsteatotic hepatopathy (non-A-D hepatitis in 6 cases, diffuse granulomatosis in 2, schistosomiasis in 1, fibrosis in 1). The only observed major complications related to LB were 2 intraparenchymal haematomas, both of which resolved spontaneously within a few months. In conclusion, based on these findings, we believe that preoperative LB in the donor selection for adult LDLT is necessary, once the initial donor screening and noninvasive evaluation is complete. Because other screening modalities can be unreliable, without preoperative LB a fraction of potential donors will be operated on inappropriately, risking both donor and recipient. The main objective of LB should be to ensure the donor's safety more than the preservation of the graft function.

GNB3 C825T polymorphism and response to interferon-alfa/ribavirin treatment in patients with hepatitis C virus genotype 1 (HCV-1) infection.

BACKGROUND/AIMS: The outcome of infection with the hepatitis C virus (HCV) has been shown to be influenced by genetic host factors. The G protein beta3 subunit (GNB3) C825T polymorphism has been shown to determine immune cell functions in vitro. We investigated the association of GNB3 genotypes with treatment response in HCV-infected patients. METHODS: We genotyped 1781 HCV-free blood donors and 232 HCV-infected patients treated with interferon-alfa/ribavirin. Sustained virologic response (SVR) was defined by undetectable HCV-RNA 24 weeks after discontinuation of therapy. Non-response (NR) was defined by positive HCV-RNA at the end of at least 24 weeks of treatment. GNB3 genotypes were determined by DNA restriction enzyme analyses. RESULTS: Genotype distribution was not significantly different in healthy controls and HCV-infected patients. Only in HCV genotype 1-infected patients a significant correlation between GNB3 CC genotype and NR could be observed (6 TT, 42 TC, 54 CC) versus SVR (11 TT, 25 TC, 19 CC) patients (P = 0.004). In a logistic regression analysis including biochemical and virologic characteristics, only GNB3 CC genotype was significantly associated with NR (OR 4.9; 95% CI = 1.4-16.5; P = 0.011). CONCLUSIONS: The GNB3 825 CC genotype is associated with NR in HCV-1-infected patients.

Impact of a self-expanding, plastic esophageal stent on various esophageal stenoses, fistulas, and leakages: a single-center experience in 39 patients.

BACKGROUND: In this study, we describe our experience with the use of a self-expanding, covered, plastic esophageal stent (SEPS). The majority of placements were difficult to treat situations, i.e., proximal or extremely proximal stent release or emergency cases in the intensive care unit. METHODS: Thirty-nine patients were treated by insertion of a SEPS by endoscopic or radiologic guidance for the following: malignant stenosis (n = 22), malignant fistula (n = 8), benign stenosis after treatment for malignant disease (n = 6), benign fistula (n = 2), and perforation or leakage after surgery of the esophagus (n = 5). RESULTS: Stent placement was technically feasible in all patients. In patients with a stenosis, esophageal passage was achieved in 92.8%. Fistulas, perforations, and leakages were sealed in 73.3%. In 6 patients (15.4%), the stent was electively removed because of the completion of the therapy. Complications included respiratory insufficiency, mediastinal emphysema, and tracheal impression in one patient each; a new fistula in two patients; bleeding in 3 patients; stent-induced ulcers in two patients; and stent migration in 8 patients. CONCLUSIONS: The therapeutical success and the complication rate after SEPS placement are similar to that reported for self-expanding metal stents. In addition, the SEPS can be readily removed, and the costs are significantly lower.

Endoscopic therapy of posttransplant biliary stenoses after right-sided adult living donor liver transplantation.

BACKGROUND & AIMS: Endoscopic treatment of biliary strictures after liver transplantation is a therapeutic challenge. In particular, outcomes of endoscopic therapy of biliary complications in the case of duct-to-duct anastomosis after living related liver transplantation are limited. The aim of this study was to evaluate the feasibility and success of an endoscopic treatment approach to posttransplant biliary strictures (PTBS) after right-sided living donor liver transplantation (RLDLT) with duct-to-duct anastomosis. METHODS: Ninety patients who received adult-to-adult RLDLT in our center were screened retrospectively with respect to endoscopic treatment of PTBS. Therapy was judged as successful when cholestasis parameters returned to normal and bile duct narrowing was reduced significantly after the completion of therapy. RESULTS: Forty of 90 RLDLT patients received duct-to-duct anastomosis, 12 (30%) showed PTBS. Seven of 12 patients were treated successfully by endoscopy; the remaining 5 patients were treated primarily by surgery. Most patients were treated by balloon dilatation followed by insertion of endoprostheses. A median of 2.5 dilatation sessions were necessary and the median treatment duration was 8 months. One patient developed endoscopy-treatable recurrent stenosis, no surgical intervention was necessary. Mild pancreatitis occurred in 7.9% and cholangitis in 5.3% of the procedures. One minor bleeding episode occurred during sphincterotomy. Bleeding was managed endoscopically. CONCLUSIONS: Endoscopic therapy of adult-to-adult right living related liver transplantation with duct-to-duct anastomosis is feasible and frequently is successful. The duct-to-duct anastomosis offers the possibility of endoscopic treatment. Endoscopic treatment of posttransplant biliary strictures is safe, with a low specific complication rate.

Removal of metabolites, cytokines and hepatic growth factors by extracorporeal liver support in children.

BACKGROUND: Molecular Adsorbents Recirculating System (MARS)-mini has recently been approved and applied in children with hepatic failure. However, its indication, efficacy and capability to induce liver regeneration remain unclear. The aim of our pilot study in children was to analyse the impact of MARS on markers of detoxification and regeneration. METHODS: In children with fulminant Wilson's disease and bridged with MARSmini for liver transplantation, we analyzed toxic metabolites (bile acids, bilirubin, lactate, ammonia, tryptophan and copper), regulators of the inflammatory cascade [nitrate, tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), methionine, cystine and hyaluronic acid] and hepatic growth factors [hepatocyte growth factor (HGF), epidermal growth factor (EGF), transforming growth factor-beta1 (TGF-beta1), cortisol, corticosteroid-binding globulin (CBG), insulin-like growth factor-1 (IGF-1), angiogenin, vascular endothelial growth factor (VEGF), IL-6 and TNF-alpha] from blood, albumin circuit and haemodialysate from four applications. RESULTS: In all four applications, transfer of toxic metabolites (6/6) and inflammatory mediators (6/6), but also of hepatic growth factors (9/10), into the albumin circuit of MARS was consistently detected. Corresponding blood levels were decreased for 3/6 metabolites, 3/6 inflammatory mediators and 1/10 growth factors and increased for 1/10 growth factors. Bridging for liver transplantation was successful with MARS. CONCLUSIONS: In our prospective study, substantial extraction of albumin-bound and water-soluble candidate substances was detected with variable effect on respective blood levels. Notably, essential factors inducing liver regeneration were simultaneously removed. These data provide a basis for evaluation of liver restoration and efficacy of liver support in children with liver failure to devise a collaborative, multicentre trial.

Severe acute pancreatitis: nonsurgical treatment of infected necroses.

OBJECTIVES: In acute pancreatitis, infection of necrosis is associated with a substantial mortality of 15% to >50% even if immediate necrosectomy, the recommended standard treatment, is performed, mainly because of the patients' critical systemic and unstable local conditions at the time of manifestation of infection. We investigated whether this dreaded complication can be managed conservatively. METHODS: We evaluated 88 consecutive patients with severe (APACHE II score, > or =11; Ranson score, > or =4) acute necrotizing pancreatitis who received ICU treatment including early antibiotic prophylaxis. Twenty-eight patients were included who developed infection of necroses, verified by fine needle aspiration, 19 +/- 6 days after admission. No patient received urgent surgery; rather, in all patients, nonsurgical therapy was continued after adapting the antibiotic regimen to bacteriology. In the further course, 12 patients were excluded due to refractory local complications eventually requiring surgical treatment 36 +/- 14 days after diagnosis of infection. RESULTS: Sixteen patients (APACHE II score: 18.1 [11-33]; Ranson score, 5.9 [4-10]) were managed with medical treatment alone. Six patients recovered without further complications; 10 patients (62%) developed single or multiple organ failure, and 2 died (mortality, 12%). CONCLUSION: These data suggest that in patients with acute necrotizing pancreatitis and infected necroses, surgery can be avoided without compromising prognosis and outcome.

Outcome after orthotopic liver transplantation in five HIV-infected patients with virus hepatitis-induced cirrhosis.

BACKGROUND: We report on our experiences with orthotopic liver transplantation (OLT) in HIV-infected patients. Between July 1998 and October 2001, five HIV-infected patients underwent OLT because of virus-induced liver cirrhosis. One patient suffered from hepatitis B virus (HBV)-, three patients from hepatitis C virus (HCV)- and one patient from HCV/HBV/HDV-related cirrhosis (HDV, hepatitis D virus). The mean duration of HIV infection was 15 years. Patients were prospectively followed up with a mean duration of 25.6 months. RESULTS: Three patients died 3, 10 and 31 months after OLT, respectively, due to graft failure. The causes of graft failure were: recurrent thrombosis of the hepatic artery, HCV-associated cholestatic hepatitis and chemotherapy-induced liver damage due to Hodgkin's disease, which was diagnosed 17 months after OLT, in addition to chronic HCV disease. The two survivors show a stable liver function and non-progredient HIV infection under antiretroviral therapy 61 and 23 months after OLT, respectively. CONCLUSIONS: A medium- or even long-term survival after OLT can be achieved in HIV-infected patients without progression of HIV disease under antiretroviral therapy. However, in our study three out of five patients died due to graft failure. Therefore, prognostic criteria have to be defined for the selection of HIV-infected patients, who may benefit from OLT.
