RESUMO

BACKGROUND: Preventing disease progression and viral suppression are the main goals of antiviral therapy in chronic hepatitis B (CHB). Liver stiffness measurement (LSM) by transient elastography is a reliable non-invasive method to assess liver fibrosis in patients with CHB. Our aim was to explore factors that may affect changes in LSMs during long term tenofovir (TDF) monotherapy in a well characterized cohort of patients with compensated CHB. METHODS: We analyzed serial LSMs in 103 adult patients with CHB who were on TDF monotherapy and had at least three LSMs over a period of 90 months. RESULTS: Twenty-five (24%) patients had advanced fibrosis at baseline. A significant decline in mean LSM between baseline and last visit (8.7 ± 6.2 kPa vs. 6.7 ± 3.3, p = 10- 3) was observed. Twenty-four (23%) patients had progression of liver fibrosis with mean increase in liver stiffness of 2.8 kPa (range: 0.2-10.2 kPa). Multivariate analysis showed that BMI ≥ 25 (OR, 0.014; 95% CI, 0.001-0.157; p = 0.001) and advanced fibrosis (OR, 5.169; 95% CI, 1.240-21.540; p = 0.024) were independently associated with a fibrosis regression of > 30% of liver stiffness compared to baseline value. CONCLUSIONS: In CHB patients TDF monotherapy resulted in liver fibrosis regression, especially in patients with advanced fibrosis. Despite the successful antiviral effect of TDF, 1 out of 4 patients had liver fibrosis progression. Obesity and advanced fibrosis at baseline were independently associated with significant liver fibrosis regression.

RESUMO

Background: The diagnosis and management of Helicobacter pylori (H. pylori) infection vary significantly, depending on country, area, and specialty. The aim of this study was to record the current practices of Greek gastroenterologists in the screening and treatment of H. pylori infection. Method: An anonymous questionnaire consisting of 19 questions about the management of H. pylori infection was sent with the aid of the Hellenic Society of Gastroenterology to all members of the Society. Results: The questionnaire was completed by 180 gastroenterologists, with a response rate of 31.4%. Diagnostic tests to confirm H. pylori infection are ordered by >90% of the gastroenterologists for patients with current peptic ulcer disease, gastric lymphoma, family history of gastric cancer, and an endoscopic appearance suggestive of gastritis. Most gastroenterologists (55.8%) also tested for H. pylori in patients with gastroesophageal reflux disease (GERD). Histopathology was the most preferred (60.6%) method when testing was decided during endoscopy, while urea breath test was the most preferred method (67.8%) regardless of endoscopy. Most gastroenterologists use quadruple eradication regimens supported by international guidelines (90%), while 65.6% of the physicians answered that they systematically recommend the addition of probiotics to standard therapy. Most physicians (82.8%) answered that they always confirm the eradication of the pathogen. Conclusions: The majority of Greek gastroenterologists conform to the recommendations of international guidelines regarding the diagnosis and management of H. pylori infection, except for the screening of patients with GERD. A considerable number of doctors use probiotics in addition to standard therapy.

RESUMO

The new coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified in December 2019, in Wuhan, China. The virus was rapidly spread worldwide, causing coronavirus disease 2019 (COVID-19) pandemic. Although COVID-19 is presented, usually, with typical respiratory symptoms (i.e., dyspnea, cough) and fever, extrapulmonary manifestations are also encountered. Liver injury is a common feature in patients with COVID-19 and ranges from mild and temporary elevation of liver enzymes to severe liver injury and, even, acute liver failure. The pathogenesis of liver damage is not clearly defined; multiple mechanisms contribute to liver disorder, including direct cytopathic viral effect, cytokine storm and immune-mediated hepatitis, hypoxic injury, and drug-induced liver toxicity. Patients with underlying chronic liver disease (i.e., cirrhosis, non-alcoholic fatty liver disease, alcohol-related liver disease, hepatocellular carcinoma, etc.) may have greater risk to develop both severe COVID-19 and further liver deterioration, and, as a consequence, certain issues should be considered during disease management. The aim of this review is to present the prevalence, clinical manifestation and pathophysiological mechanisms of liver injury in patients with SARS-CoV-2 infection. Moreover, we overview the association between chronic liver disease and SARS-CoV-2 infection and we briefly discuss the management of liver injury during COVID-19.

RESUMO

BACKGROUND: Liver transplantation is the most important therapeutic intervention for end-stage liver disease (ELD). The prioritization of these patients is based on the model for end-stage liver disease (MELD), which can successfully predict short-term mortality. However, despite its great validity and value, it cannot fully incor porate several comorbidities of liver disease, such as sarcopenia and physical frailty, variables that can sufficiently influence the survival of such patients. Subsequently, there is growing interest in the importance of physical frailty in regard to mortality in liver transplant candidates and recipients, as well as its role in improving their survival rates. AIM: To evaluate the effects of an active lifestyle on physical frailty on liver transplant candidates. METHODS: An observational study was performed within the facilities of the Department of Transplant Surgery of Aristotle University of Thessaloniki. Twenty liver tran splant candidate patients from the waiting list of the department were included in the study. Patients that were bedridden, had recent cardiovascular incidents, or had required inpatient treatment for more than 5 d in the last 6 mo were excluded from the study. The following variables were evaluated: Activity level via the International Physical Activity Questionnaire (IPAQ); functional capacity via the 6-min walking test (6MWT) and cardiopulmonary exercise testing; and physical frailty via the Liver Frailty Index (LFI). RESULTS: According to their responses in the IPAQ, patients were divided into the following two groups based on their activity level: Active group (A, 10 patients); and sedentary group (S, 10 patients). Comparing mean values of the recorded variables showed the following results: MELD (A: 12.05 ± 5.63 vs S: 13.99 ± 3.60; P > 0.05); peak oxygen uptake (A: 29.78 ± 6.07 mL/kg/min vs S: 18.11 ± 3.39 mL/kg/min; P < 0.001); anaerobic threshold (A: 16.71 ± 2.17 mL/kg/min vs S: 13.96 ± 1.45 mL/kg/min; P < 0.01); 6MWT (A: 458.2 ± 57.5 m vs S: 324.7 ± 55.8 m; P < 0.001); and LFI (A: 3.75 ± 0.31 vs S: 4.42 ± 0.32; P < 0.001). CONCLUSION: An active lifestyle can be associated with better musculoskeletal and functional capacity, while simultaneously preventing the evolution of physical frailty in liver transplant candidates. This effect appears to be independent of the liver disease severity.

RESUMO

Hepatocellular carcinoma (HCC) is an aggressive primary liver neoplasm that, according to tumor stage, can be treated with resection, transplantation, locoregional treatment options, or systemic therapy. Although interventions only in early-stage disease can offer complete tumor regression, systemic therapy in advanced disease can significantly prolong overall survival, according to pub lished clinical trials. The emergence of immunotherapy in the field of cancer therapy has had a positive impact on patients with HCC, resulting in atezolizumab-bevacizumab currently being the first-line option for treatment of advanced HCC. In light of this, application of immunotherapy in the preoperative process could increase the number of patients fulfilling the criteria for liver transplantation (LT). Implementation of this approach is faced with challenges regarding the safety of immunotherapy and the possibly increased risk of re jection in the perioperative period. Case reports and clinical trials assessing the safety profile and effectiveness of neoadjuvant immunotherapy, highlight important aspects regarding this newly evolving approach to HCC management. More studies need to be conducted in order to reach a consensus regarding the optimal way to administer immunotherapy prior to LT. In this review, we sum marize the role, safety profile and future considerations regarding the use of neoadjuvant immunotherapy prior to LT in patients with HCC.

RESUMO

BACKGROUND: Enhanced recovery after surgery (ERAS) started a revolution that changed age-old surgical stereotypical practices regarding the overall management of the surgical patient. In the last decade, ERAS has gained significant acceptance in the community of general surgery, in addition to several other surgical specialties, as the evidence of its advantages continues to grow. One of the last remaining fields, given its significant complexity and intricate nature, is liver transplantation (LT). AIM: To investigate the existing efforts at implementing ERAS in LT. METHODS: We conducted a systematic review of the existing studies that evaluate ERAS in orthotopic LT, with a multimodal approach and focusing on measurable clinical primary endpoints, namely length of hospital stay. RESULTS: All studies demonstrated a considerable decrease in length of hospital stay, with no readmission or negative impact of the ERAS protocol applied to the postoperative course. CONCLUSIONS: ERAS is a well-validated multimodal approach for almost all types of surgical procedures, and its future in selected LT patients seems promising, as the preliminary results advocate for the safety and efficacy of ERAS in the field of LT.

RESUMO

Immunoproliferative small intestinal disease is an extranodal marginal zone B-cell lymphoma that arises from mucosa-associated lymphoid tissue and is associated with defective α heavy chain protein secretion. We present a case of an 18-year-old male patient admitted with diarrhea and weight loss who had previously received a liver transplant at the age of 19 months to treat biliary atresia. He underwent a thorough investigation and was diagnosed with immunoproliferative small intestinal disease lymphoma. The patient was switched from tacrolimus to everolimus and commenced on doxycycline treatment for 6 months and achieved long-term remission. Currently, 7 years after diagnosis, he is asymptomatic without evidence of histological relapse. This is the first case of immunoproliferative small intestinal disease described in a liver transplant recipient.

RESUMO

BACKGROUND: Prognostic indicators in patients with decompensated cirrhosis are vital for the estimation of death risk. The ratio of C-reactive protein to albumin (CAR) has been verified as a prognostic marker in patients with hepatocellular carcinoma and decompensated cirrhosis related to hepatitis B virus. Neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and gamma globulins have been separately studied in cirrhosis. We evaluated the predictive role of CAR and other inflammatory markers in decompensated patients. METHODS: We prospectively studied 159 patients with stable decompensated cirrhosis, calculating the following indexes: CAR, NLR, LMR, Child-Turcotte-Pugh (CTP), and model for end-stage liver disease (MELD). RESULTS: MELD (area under the curve [AUC] 0.814) and CTP score (AUC 0.752) were superior to the other markers above in predicting patients' mortality (P<0.05). Patients with CAR<2.17 (median value) presented better times of survival: 20 months (12-27) vs. 14 months (10-17) (log rank P=0.015). NLR and LMR barely discriminated patients' prognosis. In multivariate analysis, only MELD and CTP scores were significant risk factors, whether using the proposed cutoff of 1.3 (hazard ratio [HR] 1.17 [1.106-2.44], P<0.001) or the median 2.17 CAR categorical variable (HR 1.17 [1.104-1.243], P<0.001). When patients who underwent liver transplantation were excluded, apart from the MELD and CTP scores CAR 2.17 was the only significant factor associated with the outcome (HR 3.61 [0.96-13.6], P=0.05) and detected different survival times: 10 (1-48) vs. 11 (2-38) months, log rank P=0.003. Patients with LMR≥1.9 presented significantly better renal function, in terms of true glomerular filtration rate (80±34 vs. 64±33 mL/min, P=0.004) and creatinine levels: 0.84 (0.1-1.8) vs. 0.98 (0.59-3.3) mg/dL (P=0.001). CONCLUSION: Our findings demonstrate the significance of CAR and LMR in the outcome and renal function of decompensated patients.

RESUMO

BACKGROUND: This study evaluated the efficacy, safety, and impact on renal function of everolimus in patients after liver transplantation (LT) with or without mycophenolate mofetil (MMF). METHODS: We evaluated LT recipients with calcineurin inhibitor (CNI)-related renal dysfunction after everolimus initiation. Laboratory data, including evaluation of renal function based on glomerular filtration rate (GFR) at baseline (i.e., everolimus initiation) and at the end of follow up, were analyzed. RESULTS: Fifty consecutive patients started taking everolimus at 30 months post-LT (range: 1-240), 6 as monotherapy and 44 in combination with MMF. After 30.5 months (range: 6-112), all patients were alive, without any biochemical evidence of a rejection episode or recurrence of hepatocellular carcinoma. The mean GFR, based on the Modification of Diet in Renal Disease equation, was 53±13 mL/min at baseline and 59±12 mL/min at the end of follow up (P=0.031). Eleven (22%) of the patients had GFR <60 mL/min at baseline but returned to GFR >60 mL/min by the end of follow up. In multivariate analysis, the time between the development of renal dysfunction and everolimus initiation was the only factor independently associated with GFR improvement (odds ratio [OR] 0.85, 95% confidence interval [95%CI] 0.76-0.96; P=0.007). Everolimus was stopped in 11 patients (22%) at the end of follow up because of adverse events. CONCLUSION: A CNI-free everolimus-based regimen was effective in LT recipients with renal dysfunction and was associated with an improvement in GFR.

RESUMO

Cirrhosis is an increasing cause of morbidity and mortality. Recent studies are trying to clarify the role of microbiome in clinical exacerbation of patients with decompensated cirrhosis. Nowadays, it is accepted that patients with cirrhosis have altered salivary and enteric microbiome, characterized by the presence of dysbiosis. This altered microbiome along with small bowel bacterial overgrowth, through translocation across the gut, is associated with the development of decompensating complications. Studies have analyzed the correlation of certain bacterial families with the development of hepatic encephalopathy in cirrhotics. In general, stool and saliva dysbiosis with reduction of autochthonous bacteria in patients with cirrhosis incites changes in bacterial defenses and higher risk for bacterial infections, such as spontaneous bacterial peritonitis, and sepsis. Gut microbiome has even been associated with oncogenic pathways and under circumstances might promote the development of hepatocarcinogenesis. Lately, the existence of the oral-gut-liver axis has been related with the development of decompensating events. This link between the liver and the oral cavity could be via the gut through impaired intestinal permeability that allows direct translocation of bacteria from the oral cavity to the systemic circulation. Overall, the contribution of the microbiome to pathogenesis becomes more pronounced with progressive disease and therefore may represent an important therapeutic target in the management of cirrhosis.

RESUMO

BACKGROUND: The clinical impact of relative adrenal insufficiency (AI) on patients with stable decompensated cirrhosis (DeCi) has not been yet elucidated. AIM: Explore the association between AI and outcome [death or liver transplantation (LT)] in patients with DeCi. MATERIAL AND METHODS: Patients with DeCi presenting no active complication have been included. Clinical and laboratory data, including serum levels of corticosteroid-binding globulin (CBG), interleukin (IL)-1b, IL-6 and tumor necrosis factor (TNFα) were recorded in each participant. Salivary cortisol (SC) and serum total cortisol (STC) were assessed at (T0) and 1 h (T60) after intravenous injection of 250 µg corticotropin. RESULTS: 113 consecutive patients were totally tested. Median SC was 3.9 ng/mL and 15.5 ng/mL and median STC was 10.7 µg/dL and 22.7 µg/dL at T0 and T60 respectively. The patients with AI [group 1, n = 34 (30%)] had significantly lower systolic blood pressure (106 ± 12 vs. 113 ± 13 mmHg, p = 0.05), serum sodium (133 ± 7 vs. 137 ± 12 mEq/ L, p = 0.04), HDL (29.9 ± 14 vs. 38.6 ± 18 mg/dL, p = 0.034) and albumin (2.7 ± 0.5 vs. 3.1 ± 0.5 g/dL, p = 0.002), but higher direct bilirubin (median: 1.6 vs. 0.8 mg/dL, p = 0.029) compared to those without AI [group 2, n = 79 (70%)]. Moreover, group 1 patients presented more frequently past history of spontaneous bacterial peritonitis (SBP) [10/34 (29.4%) vs. 6/79 (7.5%), p = 0.002]. AI was significantly associated with death [HR = 2.65, 95% C.I.: 1.55 - 4.52, p = 0.003 over a follow up period of 12 (6-48) months.] Conclusions. The presence of AI in patients with stable DeCi predispose to obvious clinical implications since it is associated with circulatory dysfunction, previous history of SBP and worse survival.

RESUMO

BACKGROUND: Hepatopulmonary syndrome (HPS) is a relatively common complication in patients with decompensated cirrhosis. Our aim was to evaluate the prevalence of HPS, its clinical impact, and the possible association between HPS and characteristics of patients with decompensated cirrhosis. METHODS: Patients with stable decompensated cirrhosis admitted to our department and assessed for HPS were included. For each patient, several clinical, laboratory and echocardiographic parameters as well as renal function were recorded. The severity of liver disease was evaluated according to the Model for End-stage Liver Disease and Child-Pugh scores, and renal function was assessed using 51chromium complexed with ethylene diamine tetracetic acid. In addition, the short synacthen test was performed in each patient to evaluate the adrenal function. RESULTS: Sixty-three patients were enrolled, 26 (41.3%) of whom diagnosed with HPS. In multivariate analysis, the presence of hepatocellular carcinoma [odds ratio (OR) 8.1, 95% confidence interval (CI) 5.3-27.9, P=0.045] and salivary cortisol at T60 (60 min after the intravenous injection of 250 µg corticotropin) (OR 0.88, 95%CI 0.71-0.98, P=0.045) were the factors independently associated with HPS. T60 salivary cortisol had relatively good discriminative ability for the presence of HPS (area under the curve=0.73). The presence of HPS was not associated with the outcome (P=0.22). CONCLUSION: In our cohort of patients with decompensated cirrhosis, the presence of hepatocellular carcinoma and T60 salivary cortisol were the only factors independently associated with HPS.

RESUMO

BACKGROUND AND AIMS: To investigate if urine albumin-to-creatinine ratio (UACR) is associated with the presence of glomerular filtration rate (GFR) <60 mL/min, severity of liver disease and survival in patients with stable decompensated cirrhosis. METHODS: We evaluated prospectively 220 patients (73 % male, age 52.8 ± 12 years). In each patient, assessment of GFR was based on 51chromium-EDTA. Random urine samples were obtained for measurement of UACR. RESULTS: Thirty-eight patients (17 %, group 1) had UACR ≥30 mg/g and 182 (83 %, group 2) had UACR <30 mg/g. Group 1, compared to group 2 patients, had significantly lower levels of "true" GFR (61 vs. 71 ml/min, p = 0.035). Patients with "true" GFR <60 mL/min (n = 93), compared to those with "true" GFR ≥60 mL/min (n = 127), had higher levels of UACR (16 vs. 11.3 mg/g, p = 0.023). In multivariate analysis, serum creatinine and UACR (ΟR 0.98, 95 % CI 0.95-0.99, p = 0.04) were independently associated with the presence of GFR <60 mL/min. Based on the area under the ROC curves, the best cut-off point for UACR was >16.51 mg/g giving a sensitivity 70 %, specificity 49 %, PPV 68 % and NPV 51 %. During the follow-up period [17 (6-52) months], the patients who died or underwent LT (n = 158), compared to those who remained alive (n = 62), had higher levels of UACR (41 vs. 13 mg/g, p = 0.025). Patients with UACR ≥30 mg/g had worse outcome, compared to those with UACR <30 mg/g (log rank p = 0.053). CONCLUSIONS: We showed for the first time that UACR ≥30 mg/g was associated with more severe liver disease, lower GFR and worse LT-free survival in patients with decompensated cirrhosis. However, further studies are needed to confirm these findings.

RESUMO

BACKGROUND AND AIM: Evaluation of renal function, that is, glomerular filtration rate (GFR), has become very important, but conventional mathematical formulae for GFR assessment are inaccurate in patients with cirrhosis. The aim of the present study was to compare serum creatinine (sCr)-based and serum cystatin C (cysC)-based estimated GFR (eGFR) formulae with 51 Chromium-ethylenediaminetetraacetic acid GFR (51 Chr-GFR) in patients with stable decompensated cirrhosis. METHODS: In 129 Caucasian patients with decompensated cirrhosis, we assessed sCr-based GFRs [Modification of Diet in Renal Disease and chronic kidney disease-epidemiology (CKD-EPI)-sCr formulae], cysC-based GFRs [Hoek, Larsson, and CKD-EPI-cysC equations], and the mathematical formulae, which combined both sCr and cysC [i.e. CKD-EPI-sCr-cysC and the specific for cirrhotics formula recently proposed by Mindikoglu et al. (Mindikoglu-eGFR)]. Multivariate linear regression analysis was used for GFR predictors in our cohort. RESULTS: The correlations between 51 Chr-GFR and all mathematical formulae were good (Spearman r2 > 0.68, P < 0.001). Modification of Diet in Renal Disease and CKD-EPI-sCr had lower bias (6.6 and -4.8, respectively), compared with the other eGFRs, while Mindikoglu-eGFR and CKD-EPI-sCr-cysC formulae had greater precision (17.1 and 17.3, respectively), compared with the other eGFRs. CKD-EPI-sCr and Mindikoglu-eGFR had higher accuracy (39% and 41%, respectively), compared with the other eGFRs. The factors independently associated with the 51 Chr-GFR were age, cysC, and sCr, and the new derived formula had lower bias (0.89) and similar precision (17.2) and accuracy (41%) with Mindikoglu-eGFR formula. CONCLUSION: The specific mathematical formulae derived from patients with cirrhosis seem to provide superior assessment of renal function, compared with the conventional used sCr-based and cysC-based formulae.

RESUMO

BACKGROUND/AIM: The pathogenesis and the clinical impact of diastolic dysfunction (DD) in cirrhosis remain unclear. Our aim was to investigate the factors significantly associated with the presence of DD in patients with decompensated cirrhosis on the waiting list for liver transplantation. MATERIAL AND METHODS: consecutive patients with decompensated cirrhosis, who admitted for transplant assessment, were prospectively evaluated. We assessed the independent factors associated with the presence of DD, while their discriminative ability was evaluated by AUC curve. The diagnosis of DD was based on Doppler echocardiography and classified into three categories according to the current guidelines. RESULTS: we evaluated 115 consecutive patients. Sixty six patients (57.3%-group 1) had DD and 49 (42.7%-group 2) had not DD. The 2 groups had similar Child-Pugh/MELD scores and survival. In multivariable logistic regression analysis, pulse rate (OR: 1.082, 95% CI: 1.03-1.15, p = 0.004), and UNa24h (OR: 0.98, 95% CI: 0.97- 0.99, p = 0.004) were the only variables independently associated with the presence of DD. In the subgroup of consecutive patients (n = 31) with evaluation of cytokines, those (n = 22) with DD, compared to those (n = 9) without DD, had significantly higher levels of inteleukin-6 [145 (45-2000) vs. 56 (10-149)pg/mL, p = 0.043]. CONCLUSIONS: We found that DD was independently associated with lower 24-hour urine sodium. Although no correlation was found between DD and severity of liver disease or survival, further studies are needed for final conclusions.

RESUMO

PURPOSE: Everolimus, a mammalian target of rapamycin inhibitor, has been shown to reduce growth factor-mediated cell proliferation, but data regarding its effectiveness and impact on renal function and recurrence of hepatocellular carcinoma (HCC) in liver transplant (LT) recipients are limited. METHODS: We evaluated LT recipients with a calcineurin inhibitor (CNI)-based immunosuppression regimen in whom everolimus treatment was initiated. The changes in laboratory data, including glomerular filtration rate (GFR), compared to the baseline (i.e. the day of everolimus conversion), were assessed. RESULTS: Totally, 44 consecutive patients (32 men, age 55 ± 7 years) were commenced on everolimus [indications: renal dysfunction post-LT (16 patients, group 1); prevention of HCC recurrence (21 patients) or others (7 patients), group 2] at 6 months (range 1-206) post-LT. After 48 (range 12-76) months, all patients were alive without any rejection episodes. Compared to group 2 patients, group 1 patients had significantly greater improvement in renal function (DGFR: 12 ± 5 vs. -0.4 ± 0.2 ml/min, p = 0.02). GFR at baseline (OR 0.08, p = 0.002) and the combination of everolimus + MMF (OR 0.14, p = 0.024) were the factors independently associated with improvement in renal function. Finally, HCC recurrence was observed less frequently in the everolimus group of patients (n = 21) compared to the CNI-historical control group (n = 22) with HCC before LT [0/21 (0 %) vs. 4/22 (18.5 %), log rank p = 0.055), although the two groups of recipients had similar baseline characteristics and follow-up. CONCLUSIONS: Everolimus is effective and is associated with low rates of HCC recurrence and improvement of renal function in LT recipients.

RESUMO

BACKGROUND/AIMS: The effect of hepatocellular cancer (HCC) in patients transplanted for hepatitis B and D virus (HB/DV) cirrhosis is not well studied. Our aim was to study the long-term survival outcomes of patients who underwent liver transplantation for HB/DV cirrhosis with and without HCC. METHODOLOGY: A total of 231 primary, adult, single- organ liver transplants were performed from 1990 to 2007. HB/DV was the cause of cirrhosis in 36 patients. Nine patients died during the first 3 postoperative months from surgical complications. The study group comprised the remaining 27 patients. The median follow-up was 1515 days. RESULTS: The mean patient survival was 3760 days (95% CI: 3013-4507). Six patients were diagnosed with HCC. The mean patient survival was 3011 days (95% CI: 2344-3679) and 4036 days (95% CI: 3002-5070) for recipients without and with HCC, respectively. For the same groups, the incidence of microbial infections was 61.9% and 33.3%, respectively (p=0.219). HCC has not recurred in any of the six patients. CONCLUSIONS: The mean long-term survival after liver transplantation for HB/DV and HCC surpassed 11 years. The superior survival of HCC patients is difficult to explain. The increased number (almost double) of microbial infections in the non- HCC population might be held accountable.
