TLR agonists enhance responsiveness of inflammatory innate immune cells in HLA-B*57-positive HIV patients.

HLA-B*57 affects the course of HIV infection. Under antiretroviral therapy, its effects cannot be explained by outstandingly efficient T cell responses alone but may also involve cells of innate immunity. Studying in vitro stimulation with Pam3CSK4, E. coli LPS-B5 and CpG-ODN-2216, we observed greater induction of IL-6/IL-1beta double-positive CD14+CD16++ monocytes as well as IFN-gamma-positive cytotoxic CD56highCD16neg NK cells in HLA-B*57- versus HLA-B*44-positive HIV patients, while TNF-alpha induction remained unchanged. Differences were not seen in the other monocyte and NK cell subsets or in HLA-matched healthy controls. Our findings show that, in virally suppressed HIV infection, HLA-B*57 is associated with enhanced responsiveness of inflammatory innate immune cells to TLR ligands, possibly contributing to increased vulnerability in sepsis. KEY MESSAGES: • HLA-B*57 is a host factor affecting clinical outcomes of HIV infection. • HLA-B*57 modifies inflammatory subsets of NK cells and monocytes in HIV infection. • In HLA-B*57-positive HIV patients TLR agonists induce enhanced IL-6/IL-1beta in monocytes. • NK cells from HLA-B*57 HIV patients release more IFN-gamma upon TLR costimulation. • HLA-B*57 is linked to enhanced inflammatory responsiveness to TLR ligands.

Survival of HIV/HCV co-infected patients before introduction of HCV direct acting antivirals (DAA).

HIV/HCV infection is supposed to substantially reduce survival as compared to HIV mono-infection. Here, we compared longtime-survival and causes of death in a cohort of HIV- and HIV/HCV-co-infected patients on combined antiretroviral therapy (cART), before introduction of HCV direct acting antivirals (DAA). 322 Caucasian patients with HIV (n = 176) and HIV/HCV-infection (n = 146) were enrolled into this study. All patients were recruited between 2003 and 2004 and followed until 01.01.2014. We compared overall survival between the two groups by the Kaplan-Meyer method and identified independent factors associated with long-time survival by conditional Cox regression analysis. In total 46 (14.3%) patients died during the observation period (HIV infection: n = 23 (13.1%), HIV/HCV infection: n = 23 (15.8%) but overall-survival did not differ significantly between HIV/HCV-infected and HIV mono-infected patients (p = 0.619). Survival was substantially better in patients with complete suppression of HIV replication below the level of detection than in those with residual viremia (p = 0.001). Age (p = 0.008), γ-glutamyltranspeptidase (p < 0.0001) and bilirubin (p = 0.008) were significant predictors of survival irrespective from HCV co-infection. Complete repression of HIV replication on cART is the key factor determining survival both in HIV- and HIV/HCV-co-infected patients, while HCV co-infection and therapy without DAAs seem to affect survival to a lesser extent. Thus, patients with HIV/HCV co-infection require particularly intensive cART.

Liver stiffness regression after successful Hepatitis C treatment is independent of HIV coinfection.

OBJECTIVES: The aim of the study was to assess the regression of liver stiffness after successful direct-acting antiviral (DAA) treatment in patients with hepatitis C virus (HCV) monoinfection and HCV/-HIV coinfection. In addition, we aimed to identify factors associated with liver stiffness regression. METHODS: We studied patients treated with interferon-free DAA regimens with a sustained virological response at week 12 (SVR12 ) or 24 (SVR24 ) post-treatment. Liver stiffness was assessed by transient elastography (TE) before the initiation and after the end of treatment (median 12 weeks). RESULTS: Of 214 enrolled patients, 85 (40%) were HCV monoinfected and 129 (60%) HCV/HIV coinfected. Baseline median TE values were 7.8 kPa [interquartile range (IQR) 5.9-12.0 kPa] in mono-infected patients and 10.7 kPa (IQR 7.8-17.0 kPa) in coinfected patients. Overall, the median TE value decreased from 10.1 to 6.8 kPa (n = 214; P < 0.0001). There was no difference between mono- and coinfected patients (-2.2 versus -3.3 kPa, respectively; P = 0.88), which was verified by an analysis of covariance (ANCOVA) adjusting for baseline TE values. Significant (≥ 30%) regression of liver stiffness was achieved by 45% of patients (54% with baseline TE ≥ 7.1 kPa). In multivariate analysis, a prior HCV treatment was a negative predictor of liver stiffness regression [odds ratio (OR) 0.31; P = 0.001]. A higher baseline TE value was positively associated with achieving a significant regression (OR 1.06; P = 0.02). HIV coinfection status, HCV genotype, age, sex, treatment duration, controlled attenuation parameter value, bilirubin concentration, platelet count and aspartate aminotransferase concentration were not associated with liver stiffness regression. CONCLUSIONS: Regression of liver stiffness after successful DAA treatment did not differ in patients with HCV monoinfection and those with HCV/HIV coinfection. Half of all patients achieved a significant (≥ 30%) regression. Prior treatment for HCV was a negative predictor for this endpoint, while a higher baseline TE value was positively associated with regression.

Non-invasive fecal microbiota transplantation for recurrent Clostridium difficile infection in a patient presenting with hypertensive disorder post interventionem.

Fecal microbiota transplantation has gathered much attention due to its high efficacy in resolving recurrent Clostridium difficile infection. Until today, it is recognized as a safe procedure without any severe side effects. Patients with impaired conscious states suffering from recurrent episodes of aspiration are at increased risk by endoscopic interventions needed during standard approaches for fecal microbiota transplantation application.Here, we illustrate the case of a tetraplegic patient undergoing fecal microbiota transplantation due to his fifth recurrent episode of Clostridium difficile infection using a self-advancing nasal jejunal feeding tube as effective minimal-invasive option of fecal microbiota transplantation application. Persistent aggravation of arterial hypertension, which developed post-intervention in this patient, could be interpreted as a hitherto unknown side effect of fecal microbiota transplantation in this setting. Moreover, this is a further hint for a link between the intestinal microbiome and arterial hypertension in general.

Survival after 131I-labeled lipiodol therapy for hepatocellular carcinoma. A single-center study based on a long-term follow-up.

UNLABELLED: This study investigated the efficacy of 131iodine-labeled lipiodol (131I-lipiodol) as a palliative therapy, evaluated overall survival (OS) across Barcelona Clinic Liver Cancer (BCLC) stages, and determined the main prognostic factors influencing OS in patients with hepatocellular carcinoma (HCC). PATIENTS, METHODS: We retrospectively analyzed 57 (44 men; mean age, 65.7 years; mean activity per session, 1.6 GBq; mean cumulative activity in patients with >1 sessions, 3.9 GBq) HCC patients who underwent 131I-lipiodol therapy. A majority of patients exhibited Child-Pugh class B (53.6%) disease and a good Eastern Cooperative Oncology Group performance status (0-1; 72%). Multinodular disease was observed in 87.7% patients, bilobar disease in 73%, and portal vein occlusion (PVO) in 54%. Furthermore, 21.1% patients were staged as BCLC B and 59.6 % as BCLC C. All patients were followed until death. RESULTS: The median OS was 6.4 months, which varied significantly with disease stage (median OS for BCLC A, B, C, and D was 29.4, 12.0, 4.6, and 2.7 months, respectively; p = 0.009); Child-Pugh score and class; presence of ascites, PVO, or extrahepatic disease; largest lesion size; favourable treatment response; international normalized ratio, baseline albumin and alpha-fetoprotein levels. Patients with a Child-Pugh A liver disease had a longer OS. CONCLUSION: Currently, different treatment modalities for HCC include radioembolization, transarterial chemoembolization, and systemic therapy with sorafenib; however, 131I-lipiodol therapy remains a feasible alternative for patients without a favourable response to other therapies, particularly for patients with Child-Pugh A liver cirrhosis.

Treatment of severe, nonfulminant acute hepatitis B with lamivudine vs placebo: a prospective randomized double-blinded multicentre trial.

Acute hepatitis B virus (aHBV) infection can lead to fulminant liver failure, which likely is prevented by early lamivudine therapy. Even nonfulminant but severe acute hepatitis B can lead to significant morbidity and impaired quality of life. Therefore, lamivudine was evaluated in patients with severe aHBV in a placebo-controlled trial. Patients with severe aHBV infection (ALT >10× ULN, bilirubin >85 µm, prothrombin time >50%) were prospectively treated with lamivudine 100 mg/day or with placebo within 8 days after the diagnosis. The primary end point was time to bilirubin <34.2 µm. Secondary end points were time to clear HBsAg and HBV-DNA, development of anti-HBs and normalization of ALT. Eighteen cases were randomized to lamivudine, 17 to placebo. 94% of patients were hospitalized. No individual progressed to hepatic failure; all but one patient achieved the primary end point. Due to smaller than expected patient numbers, all study end points did not become statistically significant between treatment arms. Median time end points [in days] were bilirubin <34.2 µm (26.5 vs 32), ALT normalization (35 vs 48) and HBsAg clearance (48 vs 67) referring to earlier recovery under lamivudine, in contrast to loss of HBV-DNA (62 vs 54) and development of anti-HBs (119 vs 109). In all but two patients (one in every group), HBsAg clearance was reached in the study. Adverse events occurred more frequently during lamivudine therapy, but did not reach statistical significance. Lamivudine may ameliorate severe aHBV infection, but limited patient numbers prevented definite conclusions.

Spontaneous bacterial peritonitis by Pasteurella multocida under treatment with rifaximin.

Spontaneous bacterial peritonitis (SBP) is a life-threatening complication of liver cirrhosis. Recently, rifaximin, a non-absorbable antibiotic which is used to prevent recurrent hepatic encephalopathy, has been proposed as effective prophylaxis for SBP. Here, we present an unusual case of SBP under treatment with rifaximin. A 50-year-old woman with liver cirrhosis was admitted because of tense ascites and abdominal pain. She was under long-term oral prophylaxis with rifaximin due to hepatic encephalopathy. Paracentesis revealed SBP caused by Pasteurella multocida, which was sensitive to multiple antibiotics, including rifaximin. Treatment with ceftriaxone resulted in rapid resolution of the peritonitis and restoration of the patient. Since P. multocida is usually transmitted from pets, the patient's cat was tested and could be identified as the most likely source of infection. This case should elicit our awareness that uncommon pathogens and unusual routes of transmission may lead to SBP, despite antibacterial prophylaxis with non-absorbable antibiotics. Nevertheless, such infections may still remain sensitive to systemic therapy with conventional antibiotics.

CCR5-Δ32 genotype does not improve predictive value of IL28B polymorphisms for treatment response in chronic HCV infection.

IL28B polymorphisms strongly predict spontaneous and treatment-induced clearance of hepatitis C virus (HCV) infection. A recent study proposed a 32-base pair deletion in the CC-chemokine receptor 5 (CCR5) gene (CCR5-Δ32) interacting with the IL28B polymorphisms to influence spontaneous HCV clearance. The aim of this study was to clarify the role of CCR5-Δ32 in treatment-induced clearance of chronic hepatitis C (CHC). A cross-sectional cohort of 813 Caucasian patients with CHC genotype 1 (365 responders and 448 non-responders) who had received standard of care dual therapy with interferon (IFN)-α and ribavirin (RBV) was genotyped for the CCR5-Δ32 and IL28B polymorphisms to examine their interaction with respect to treatment response. CCR5-Δ32 did not influence treatment-induced recovery to IFN-α/RBV in CHC, and did not improve prediction of sustained virological response in the context of the IL28B polymorphisms in a multivariate model. CCR5-Δ32 homozygotes were significantly more frequent in those with CHC than healthy controls in the European cohorts (2.9% vs 0.4%, P<0.0001), but not in Australians of European ancestry. In conclusion, CCR5-Δ32 does not influence treatment response in the context of IL28B polymorphisms. Although CCR5-Δ32 may affect viral clearance within closely controlled geographical and genetic environments, we found no effect in larger cohorts treated with dual therapy.

Orthotopic liver transplantation in human-immunodeficiency-virus-positive patients in Germany.

Objectives. This summary evaluates the outcomes of orthotopic liver transplantation (OLT) of HIV-positive patients in Germany. Methods. Retrospective chart analysis of HIV-positive patients, who had been liver-transplanted in Germany between July 1997 and July 2011. Results. 38 transplantations were performed in 32 patients at 9 German transplant centres. The reasons for OLT were end-stage liver disease (ESLD) and/or liver failure due to hepatitis C (HCV) (n = 19), hepatitis B (HBV) (n = 10), multiple viral infections of the liver (n = 2) and Budd-Chiari-Syndrome. In July 2011 19/32 (60%) of the transplanted patients were still alive with a median survival of 61 months (IQR (interquartile range): 41-86 months). 6 patients had died in the early post-transplantation period from septicaemia (n = 4), primary graft dysfunction (n = 1), and intrathoracal hemorrhage (n = 1). Later on 7 patients had died from septicaemia (n = 2), delayed graft failure (n = 2), recurrent HCC (n = 2), and renal failure (n = 1). Recurrent HBV infection was efficiently prevented in 11/12 patients; HCV reinfection occurred in all patients and contributed considerably to the overall mortality. Conclusions. Overall OLT is a feasible approach in HIV-infected patients with acceptable survival rates in Germany. Reinfection with HCV still remains a major clinical challenge in HIV/HCV coinfection after OLT.

[Expert opinion on boceprevir- and telaprevir-based triple therapies of chronic hepatitis C]. / Expertenempfehlungen zur Triple-Therapie der HCV-Infektion mit Boceprevir und Telaprevir.

With the approval of boceprevir and telaprevir the standard treatment of chronic hepatitis C virus (HCV) genotype 1 infection will be the triple therapy of a HCV protease inhibitor together with pegylated interferon alfa and ribavirin. In clinical studies a significant increase of sustained virological response rates from 38 - 44 % to 63 - 75 % for treatment-naïve and from 17 - 21 % to 59 - 66 % in treatment-experienced patients in comparison to the dual combination therapy with pegylated interferon alfa and ribavirin alone has been demonstrated. In addition, a large number of treatment-naïve patients and relapsers benefit from shorten treatment durations to 24 - 28 weeks. However, important differences exist between the administration of boceprevir and telaprevir in terms of a pegylated interferon alfa/ribavirin lead-in phase, the duration of dosing of the protease inhibitor, the overall treatment duration, HCV RNA measurements for response guided treatment durations and stopping rules. Furthermore, triple therapies with boceprevir and telaprevir may be associated with selection of resistant viral variants, new adverse events and clinically relevant drug-drug interactions. The present review gives an overview on the results of underlying clinical studies together with a guideline for the practical management of boceprevir- and telaprevir-based triple therapies.

Toll-like receptor (TLR) 2 promoter and intron 2 polymorphisms are associated with increased risk for spontaneous bacterial peritonitis in liver cirrhosis.

BACKGROUND & AIMS: Toll-like receptor (TLR) 2 and nucleotide-binding oligomerisation domain (NOD) 2 recognize distinct pathogen-associated molecular patterns (PAMS) on the cell surface and in the cytoplasm, respectively. Since they may contribute to susceptibility to spontaneous bacterial peritonitis (SBP), we studied the effects of TLR2 gene variants on susceptibility for SBP in relation to the previously reported NOD2 alleles. METHODS: Overall, 150 patients with liver cirrhosis and ascites were genotyped for TLR2 gene variants -16934 (rs4696480), Arg753Gln (rs5743708), Pro631His (rs5743704) and the TLR2 GT microsatellite polymorphism in intron 2. Patients were monitored for SBP over two years. TLR2 SNPs were identified by hybridization probe assays on a LightCycler system. Numbers of GT repeats were determined with an ABI310 sequencer and Genescan Analysis 2.1 software. RESULTS: Fifty two patients (35%) had SBP. Unlike the TLR2 Arg753Gln and Pro631His mutations, SBP was significantly more frequent in patients with the TLR2 -16934 TT genotype (38.5% vs. 15.3%; p = 0.002) and in carriers with two long tandem GT repeat alleles (>20) (53.8% vs. 25.5%; p = 0.001). A multivariate analysis confirmed TLR2 GT microsatellite polymorphism (OR = 3.8, p = 0.002) and NOD2 variants (OR = 3.3, p = 0.011) as independent predictors of SBP, and the simultaneous presence of both risk factors indicated a particularly high risk for SBP (OR = 11.3, p = 0.00002). CONCLUSIONS: Analogous to NOD2 risk variants, TLR2 polymorphisms indicate increased susceptibility toward SBP in cirrhotic patients with ascites, and the combination of the TLR2 GT microsatellite polymorphism with at least one NOD2 risk variant enables improved identification of patients with a high risk for SBP.

Correlation of transient elastography with APRI and FIB-4 in a cohort of patients with congenital bleeding disorders and HCV or HIV/HCV coinfection.

SUMMARY: Patients with inherited bleeding disorders frequently suffer from chronic hepatitis C virus (HCV) mono- or human immunodeficiency virus (HIV)/HCV coinfection. Non-invasive markers for liver fibrosis are warranted for these patients. We tested a large cohort of haemophilic patients with HCV mono- or HIV/HCV coinfection for correlation of transient elastography (TE) with two simple surrogate markers of liver fibrosis and for differences in fibrosis stages according to these markers. We prospectively enrolled HCV-positive patients with congenital bleeding disorders with or without HIV coinfection. Liver function tests and platelet counts were determined and TE was performed. Aspartate aminotransferase-to-platelet ratio index (APRI) and a simple index called FIB-4 were calculated and results were correlated with TE. A total number of 174 patients were included (23% HCV, 36% HIV/HCV coinfected, 33% with cleared HCV and 8% with ongoing HIV but cleared HCV). TE correlated significantly with APRI and FIB-4 (r = 0.60; P < 0.001 and r = 0.54; P < 0.001 respectively). This correlation was pronounced in patients with ongoing HCV infection (r = 0.67; P < 0.001 and r = 0.60; P < 0.001). Prediction of advanced fibrosis resulted in concordance rates >80% with combinations of TE plus APRI and APRI plus FIB-4. HIV/HCV coinfected patients did not present with advanced fibrosis stages when compared with HCV-monoinfected patients. Combinations of two non-invasive markers may significantly reduce the number of liver biopsies in patients with bleeding disorders and advanced liver fibrosis. Furthermore, our data support previous studies that observed a favourable outcome in patients with HIV/HCV and a preserved immune function in times of highly active antiretroviral therapy.

Renal impairment after liver transplantation - a pilot trial of calcineurin inhibitor-free vs. calcineurin inhibitor sparing immunosuppression in patients with mildly impaired renal function after liver transplantation.

OBJECTIVES: Chronic kidney disease is frequent in patients after orthotopic liver transplantation (OLT) and has impact on survival. Patients receiving calcineurin inhibitors (CNI) are at increased risk to develop impaired renal function. Early CNI reduction and concomitant use of mycophenolat mofetil (MMF) has been shown to improve renal function. METHODS: The aim of this trial was to compare dose-reduced CNI/MMF versus CNI-free MMF/prednisone-based treatment in stable patients after OLT with respect to glomerular filtration rate (GFR). 21 patients (GFR 44.9 ' 9.9 mL/min/1.73m2 measured by 99m-Tc-DTPA-clearance, serum creatinine (SCr) 1.5 ' 0.42 mg/dL) were randomized either to exchange CNI for 10 mg prednisone (group 1; n = 8) or to receive CNI at 25% of the initial dose (group 2; n = 13) each in combination with 1000 mg MMF b.i.d. RESULTS: At month 12 mean SCr (-0.3 ' 0.4 mg/dL, p = 0.031) and GFR improved (8.6 ' 13.1 mL/min/ 1.73m superset2, p = 0.015) in group 2 but remained unchanged in group 1. Main side effects were gastroinstestinal symptoms (14.3%) and infections (4.8%). Two biopsy proven, steroid-responsive rejections occurred. In group 1 mean diastolic blood pressure (BP) increased by 11 ' 22 mmHg (p = 0.03). CONCLUSIONS: Reduced dose CNI in combination with MMF but not CNI-free-immunosuppression leads to improvement of GFR in patients with moderately elevated SCr levels after OLT. Addition of steroids resulted in increased diastolic blood pressure presumably counterbalancing the benefits of CNI withdrawal on renal function.

Keratin 18 provides resistance to Fas-mediated liver failure in mice.

BACKGROUND: Keratins are intermediate filament proteins of epithelial cells with pivotal functions for cell integrity. They comprise keratins 18 [K18] and 8 [K8] in hepatocytes. Keratins are of major importance for an intact cellular microarchitecture and have protective functions in human liver diseases. In mice, K8 has been demonstrated to protect against Fas-antibody-induced liver failure by direct interaction with apoptotic regulators, while the role of K18 remains unresolved. MATERIALS AND METHODS: We analysed effects of K18 deficiency on Fas-induced liver failure in mice. We determined survival and analysed induction of apoptosis after injection of the agonistic Fas antibody Jo2 into K18(-/-) and wild-type control mice by TUNEL assay and fluorometrically analysed caspase-3, -8 and -9 activities 1, 2 and 3 h after Jo2 injection. RESULTS: In K18(-/-) mice, survival of Fas-antibody treated mice was significantly shorter than that of wild-type controls (P = 0.02). However, shortened survival of K18(-/-) mice was caused by increased hepatic damage but was not correlated to enhanced induction of apoptotic pathways, as neither numbers of TUNEL positive apoptotic cells nor activities of caspases-3, -8 and -9 differed between K18(-/-) and K18(+/+) mice at any point of time. CONCLUSION: K18(-/-) mice are significantly more susceptible to Fas-antibody-induced liver failure. The cytoprotective effect of K18 is not explained by a differential activation of caspases-3, -8 and -9, suggesting that K18 does not directly interfere with apoptotic regulators. Importantly, however, K18 exerts significant protective functions by other mechanisms.

Challenges and controversies in haemophilia care in adulthood.

Overall life expectancy and quality of life among persons with haemophilia have increased in recent years, primarily because of the advances in factor replacement therapy and better treatment of infectious diseases. Older haemophilic patients now face aging co-morbidities that are common in the general male population, such as cardiovascular or metabolic diseases, prostate hypertrophy and hepatic, prostate and other cancers. The prevalence of cardiovascular disease and incidence of vascular events among older haemophilic patients can be expected to increase and haemophilic patients may become prone to some cardiovascular risk factors, warranting preventative measures. The treatment of long-term complications of hepatitis C virus infection such as liver cirrhosis and hepatic cancer can be expected to be required in a large portion of the older haemophilia population for some years to come. Appropriate antiviral treatment and close monitoring for possible disease advancement will constitute an important part of routine medical care, and special considerations may be appropriate in conjunction with invasive procedures, chemo- or radiotherapy. At the moment, hard data on which to base the management of these conditions are largely lacking, but can be expected to increase dramatically in the coming decades. In the meantime, the ageing population of haemophilia patients should be offered the same comprehensive health care offered to the general population, which may require a restructuring of health care delivery.

Overweight HIV patients with abdominal fat distribution treated with protease inhibitors are at high risk for abnormalities in glucose metabolism - a reason for glycemic control.

BACKGROUND: In HIV patients, disorders in glucose metabolism seem to be side effects of highly active antiretroviral therapy (HAART) which may be favoured by obesity, abdominal fat accumulation and familial disposition for diabetes mellitus (DM). The aim of our study was to identify patients at high risk for abnormalities in glucose metabolism taking into account HAART, familial disposition for DM and anthropometric parameters. METHODS: Plasma glucose, insulin, c-peptide and insulin resistance (homeostasis model assessment, HOMA) were determined in 44 HIV patients [16 without HAART, 19 with protease inhibitors (PI), 9 without PI (non-PI)] and in 11 healthy subjects. Glucose tolerance was determined by standard procedures. Body mass index (BMI), triceps skin fold thickness and waist circumference were measured and the waist-to-hip-ratio was calculated. Familial disposition for DM was assessed by questionnaire. RESULTS: Impaired fasting glucose was observed in 28% of HAART-treated patients (21% with PI, 7% non-PI), in 13% of HAART-naive but none in healthy controls. 58% of PI, 44% of non-PI, 38% of HAART-naive and none of healthy controls had a HOMA-index > 2.5 which indicates insulin resistance. HAART-treated patients had significantly higher fasting glucose levels (PI: 97 +/- 11 mg/dL, p = 0.048; non-PI: 109 +/- 58 mg/dL, p = 0.009) compared to healthy controls (72 +/- 8 mg/dL). HOMA-Index was higher in PI treated patients (3.74 +/- 3.08) than in HIV negative controls (0.95 +/- 0.28, p = 0.018). The duration of HAART (p = 0.045), overweight and familial disposition for DM (p = 0.017) significantly affected fasting glucose among PI users. Waist circumference affected c-peptide (p = 0.046) concentration in these patients. CONCLUSION: HIV patients on long-term PI therapy with overweight and familial disposition for DM are at high risk to develop abnormalities of glucose metabolism. Thus, measurements of HOMA-Index, BMI and waist circumference should be routinely done especially in PI medicated patients.

Course and therapy of acute liver failure.

OBJECTIVES AND METHODS: Despite liver transplantation and advances in intensive care medicine fulminant hepatic failure [FHF] remains a life-threatening condition. Actual observations of the clinical course of these patients are rare. Therefore, we analyzed course of disease and survival in all patients treated for FHF at the University of Bonn between 1998 and 2004 and compared it to the patients treated for FHF during 1992-1997. RESULTS: 35 patients were treated for FHF during this period. FHF was viral induced in 13 patients (HBV n = 11, HAV n = 2), toxic in nine, cryptogenic in eleven and autoimmune and hyperthermia in one patient each. According to London- and/or Clichy criteria 16 patients were transplanted. Four of them died during the first year after transplantation due to infectious and hemorrhagic complications. Three patients died without liver-transplantation. All together, 1-year survival was 80%. When compared to patients with FHF analyzed in the period 1992-1997 numbers of patients with FHF in our centre had increased from 16 to 35 patients and 1-year survival improved from 67.5% to 80%. This improved survival was associated with a lower proportion of transplanted patients (45% versus 68%). CONCLUSIONS: These changes reflect advances in therapy of patients with FHF, which enables a greater proportion of patients to survive without the need for transplantation.
