Multidrug-resistant bacterial infections after liver transplantation: Prevalence, impact, and risk factors.

BACKGROUND & AIMS: Infections by multidrug-resistant bacteria (MDRB) are an increasing healthcare problem worldwide. This study analyzes the incidence, burden, and risk factors associated with MDRB infections after liver transplant(ation) (LT). METHODS: This retrospective, multicenter cohort study included adult patients who underwent LT between January 2017 and January 2020. Risk factors related to pre-LT disease, surgical procedure, and postoperative stay were analyzed. Multivariate logistic regression analysis was performed to identify independent predictors of MDRB infections within the first 90 days after LT. RESULTS: We included 1,045 LT procedures (960 patients) performed at nine centers across Spain. The mean age of our cohort was 56.8 ± 9.3 years; 75.4% (n = 782) were male. Alcohol-related liver disease was the most prevalent underlying etiology (43.2.%, n = 451). Bacterial infections occurred in 432 patients (41.3%) who presented with a total of 679 episodes of infection (respiratory infections, 19.3%; urinary tract infections, 18.5%; bacteremia, 13.2% and cholangitis 11%, among others). MDRB were isolated in 227 LT cases (21.7%) (348 episodes). Enterococcus faecium (22.1%), Escherichia coli (18.4%), and Pseudomonas aeruginosa (15.2%) were the most frequently isolated microorganisms. In multivariate analysis, previous intensive care unit admission (0-3 months before LT), previous MDRB infections (0-3 months before LT), and an increasing number of packed red blood cell units transfused during surgery were identified as independent predictors of MDRB infections. Mortality at 30, 90, 180, and 365 days was significantly higher in patients with MDRB isolates. CONCLUSION: MDRB infections are highly prevalent after LT and have a significant impact on prognosis. Enterococcus faecium is the most frequently isolated multi-resistant microorganism. New pharmacological and surveillance strategies aimed at preventing MDRB infections after LT should be considered for patients with risk factors. IMPACT AND IMPLICATIONS: Multidrug-resistant bacterial infections have a deep impact on morbidity and mortality after liver transplantation. Strategies aimed at improving prophylaxis, early identification, and empirical treatment are paramount. Our study unveiled the prevalence and main risk factors associated with these infections, and demonstrated that gram-positive bacteria, particularly Enterococcus faecium, are frequent in this clinical scenario. These findings provide valuable insights for the development of prophylactic and empirical antibiotic treatment protocols after liver transplantation.

Frailty Changes After Liver Transplantation. Results From a Spanish Multicenter Prospective Cohort Study.

Introduction: Until now, there has been limited evidence, primarily from US cohorts, focusing on frailty as a patient-oriented outcome after liver transplantation (LT). Our study aimed to explore the relationship between pre- and post-LT frailty in a multicenter European cohort of outpatients with cirrhosis undergoing LT. Methods: We conducted a prospective analysis of data from 180 LT recipients recruited between 2018 and 2020 from 5 Spanish centers. Participants underwent objective and subjective frailty assessments using the Liver Frailty Index (LFI) and the Subjective Clinician Assessment (SCA) pretransplant and at 3- and/or 6-mo posttransplant. Results: The median pretransplant LFI was 3.9, showing minimal change at 3 mo (3.8; P = 0.331) and improvement at 6-mo post-LT (3.6; P = 0.001). Conversely, the SCA significantly improved early post-LT: at 3 mo, poor SCA decreased from 11% to 1%, and good SCA increased from 54% to 89% (P < 0.001), remaining stable between 3- and 6-mo post-LT. Multivariable analysis revealed that each 0.1 increase in pretransplant LFI correlated with a reduced probability of being robust at 3-mo (odds ratio [OR] = 0.75; P < 0.001) and 6-mo post-LT (OR = 0.74; P < 0.001). There was poor concordance between SCA and LFI, with SCA underestimating frailty both pre- and post-LT (Kappa < 0.20). Conclusion: In our European cohort, incomplete improvement of physical frailty was observed, with <20% achieving robust physical condition within 6-mo post-LT. The pretransplant LFI strongly predicted posttransplant frailty. As the SCA tends to overestimate physical function, we recommend using both subjective and objective tools for frailty assessment in LT candidates and recipients.

Screening and risk of hepatocellular carcinoma in patients with advanced fibrosis after hepatitis C virus eradication.

INTRODUCTION: The risk of hepatocellular carcinoma (HCC) after eradication of the hepatitis C virus (HCV) is highly variable in patients with advanced fibrosis (F3). Long-term surveillance for HCC after sustained virological response (SVR) is controversial in these patients. Our objective is to describe the post-SVR follow-up in clinical practice in patients with F3 and determine the predictive factors for the development of HCC. PATIENTS AND METHODS: a multicenter, observational, and retrospective study, which included HCV-monoinfected patients with F3 fibrosis determined by transient elastography who achieved SVR between 2015 and 2022 and with follow-up until May 2023. Clinical-demographic, laboratory, elastography, and ultrasound variables were recorded before and after treatment. A descriptive and inferential analysis, Cox regression analysis, and survival analysis were carried out with the R statistical software. RESULTS: 219 patients were included (65.3% men, median age 57 years). 175 (79.9%) received ultrasound screening after SVR for 62 [6-90] months. The prescribing service was the only independent variable related to performing ultrasound surveillance (p=0.004). Eight patients developed HCC. In multivariate analysis adjusted for sex, age, presence of diabetes, and alcohol consumption, a post-SVR FIB-4 ≥ 3.25 was associated with a 12-fold increase in HCC risk. The cumulative probability of HCC was higher in the group of patients with FIB-4 ≥ 3.25 after SVR (p<0.001). CONCLUSION: post-SVR follow-up of patients with F3 fibrosis is variable in clinical practice. Using the FIB-4 after SVR allows us to identify those patients with a higher risk of HCC who benefit from biannual ultrasound screening.

Waiting time dictates impact of frailty: A Spanish multicenter prospective study.

Background & Aims: Frailty is prevalent in liver transplant (LT) candidates. It is considered an independent predictor of adverse outcomes pre- and post-transplant according to data obtained in the United States. We aimed to externally validate the liver frailty index (LFI) in a multicenter cohort of LT candidates. Methods: Outpatients with cirrhosis were prospectively recruited from five Spanish centers (2018-2020). Patients were defined as "frail" by an optimal cut-off of LFI ≥4.5. Patients were followed for at least 6 months to study associations of pre-LT frailty with pre- and post-transplant mortality, length of hospital and intensive care unit (ICU) stays, risk of early (<30 days) and late (30-90 days) post-transplant complications, retransplantation and cardiovascular events. Results: Of 212 patients included, 45 patients (21%) were frail pre-LT, and the median LFI was 3.9 (IQR 3.5-4.4). After a median waiting time of 78 days, 2% died or were delisted for clinical worsening. The LFI at baseline was not predictive of mortality/delisting in LT candidates in univariable or multivariable analyses after adjusting for age and MELD-Na score (hazard ratio 1.48; p = 0.586). In contrast, compared to non-frail patients, frail LT candidates had a significantly higher length of hospital stay (9 vs. 13 days; p = 0.001) and rate of early (<30 days) post-transplant complications (55% vs. 100%; p = 0.021). Conclusions: In the context of a short LT waiting time, frailty does not impact pretransplant mortality and/or delisting. In contrast, LT frailty is predictive of higher post-transplant complication rates and length of hospital stay. Whether strategies aimed at pre- and/or re-habilitation are beneficial in settings with short waiting times needs to be confirmed in prospective studies. Impact and implications: Literature is scarce on the actual impact of physical frailty on adverse outcomes in the liver transplant scenario outside North America. Evidence-based justification to extend the use of objective frailty tools in the decision-making processes in other liver transplant settings is needed. This study is the first to evaluate the predictive value of the liver frailty index in outpatients in the European liver transplant setting, showing that in a low MELD, high access system, frailty does not impact pretransplant mortality and/or delisting but is predictive of higher complication rates and longer post-transplant length of stay. In practical ways, physicians should consider physical frailty as a vital sign to be measured systematically and routinely during clinic visits; researchers are encouraged to initiate prospective studies to evaluate the benefit of applying strategies aimed at pre- and or re-habilitation in liver transplant settings with short waiting times.

Best practices during COVID-19 pandemic in solid organ transplant programs in Spain.

Clinical management of transplant patients abruptly changed during the first months of COVID-19 pandemic (March to May 2020). The new situation led to very significant challenges, such as new forms of relationship between healthcare providers and patients and other professionals, design of protocols to prevent disease transmission and treatment of infected patients, management of waiting lists and of transplant programs during state/city lockdown, relevant reduction of medical training and educational activities, halt or delays of ongoing research, etc. The two main objectives of the current report are: 1) to promote a project of best practices in transplantation taking advantage of the knowledge and experience acquired by professionals during the evolving situation of the COVID-19 pandemic, both in performing their usual care activity, as well as in the adjustments taken to adapt to the clinical context, and 2) to create a document that collects these best practices, thus allowing the creation of a useful compendium for the exchange of knowledge between different Transplant Units. The scientific committee and expert panel finally standardized 30 best practices, including for the pretransplant period (n = 9), peritransplant period (n = 7), postransplant period (n = 8) and training and communication (n = 6). Many aspects of hospitals and units networking, telematic approaches, patient care, value-based medicine, hospitalization, and outpatient visit strategies, training for novelties and communication skills were covered. Massive vaccination has greatly improved the outcomes of the pandemic, with a decrease in severe cases requiring intensive care and a reduction in mortality. However, suboptimal responses to vaccines have been observed in transplant recipients, and health care strategic plans are necessary in these vulnerable populations. The best practices contained in this expert panel report may aid to their broader implementation.

Effects of everolimus plus minimized tacrolimus on kidney function in liver transplantation: REDUCE, a prospective, randomized controlled study

Background and aim: reduction in calcineurin inhibitor levels is considered crucial to decrease the incidence of kidney dysfunction in liver transplant (LT) recipients. The aim of this study was to evaluate the safety and impact of everolimus plus reduced tacrolimus (EVR + rTAC) vs. mycophenolate mofetil plus tacrolimus (MMF + TAC) on kidney function in LT recipients from Spain.Methods: the REDUCE study was a 52-week, multicenter, randomized, controlled, open-label, phase 3b study in de novo LT recipients. Eligible patients were randomized (1:1) 28 days post-transplantation to receive EVR + rTAC (TAC levels ≤ 5 ng/mL) or to continue with MMF + TAC (TAC levels = 6-10 ng/mL). Mean estimated glomerular filtration rate (eGFR), clinical benefit in renal function, and safety were evaluated.Results: in the EVR + rTAC group (n = 105), eGFR increased from randomization to week 52 (82.2 [28.5] mL/min/1.73 m2 to 86.1 [27.9] mL/min/1.73 m2) whereas it decreased in the MMF + TAC (n = 106) group (88.4 [34.3] mL/min/1.73 m2 to 83.2 [25.2] mL/min/1.73 m2), with significant (p < 0.05) differences in eGFR throughout the study. However, both groups had a similar clinical benefit regarding renal function (improvement in 18.6 % vs. 19.1 %, and stabilization in 81.4 % vs. 80.9 % of patients in the EVR + rTAC vs. MMF + TAC groups, respectively). There were no significant differences in the incidence of acute rejection (5.7 % vs. 3.8 %), deaths (5.7 % vs. 2.8 %), and serious adverse events (51.9 % vs. 44.0 %) between the 2 groups.Conclusion: EVR + rTAC allows a safe reduction in tacrolimus exposure in de novo liver transplant recipients, with a significant improvement in eGFR but without significant differences in renal clinical benefit 1 year after liver transplantation.

Efficacy and Safety of the Combination of Pravastatin and Sorafenib for the Treatment of Advanced Hepatocellular Carcinoma (ESTAHEP Clinical Trial).

Pravastatin has demonstrated anti-tumor activity in preclinical and clinical studies. This multicentric randomized double-blind placebo-controlled phase II study (NCT01418729) investigated the efficacy and safety of sorafenib + pravastatin combination on the overall survival (OS) and time to progression (TTP) of patients with advanced hepatocellular carcinoma (aHCC). A total of 31 patients were randomized. Median OS did not differ between both groups (12.4 months for the sorafenib + pravastatin group vs. 11.6 months for the control group). Of note, however, the radiological TTP was higher in patients treated with sorafenib + pravastatin than in the control group (9.9 months vs. 3.2 months; p = 0.008). Considering all the study population, the presence of portal vein thrombosis (PVT) was associated with worse OS, being lower in patients with PVT compared to patients without PVT (6.3 months vs. 14.8 months; p = 0.026). Data also showed a decrease in OS in patients with vascular invasion (VI) compared to patients who did not present it (6.3 months vs. 14.8 months; p = 0.041). The group of patients without dermatological events (DE) showed lower OS (6.9 months vs. 14.5 months; p = 0.049). In conclusion, combination of sorafenib + pravastatin was safe and well-tolerated, prolonging the TTP of patients with aHCC but not improving the OS compared to sorafenib + placebo. The absence of PVT and VI and the development of DE are positive prognostic factors of sorafenib response.

Impact of sustained virological response with DAAs on gastroesophageal varices and Baveno criteria in HCV-cirrhotic patients.

BACKGROUND: Direct-acting antivirals (DAAs) show high efficacy and safety in HCV-cirrhotic patients, but most maintain clinically significant portal hypertension after sustained virological response (SVR). Non-invasive Baveno and expanded-Baveno criteria can identify patients without high-risk gastroesophageal varices (GEV) who have no need for endoscopic surveillance. However, data after SVR are scarce. We performed a multicenter study to evaluate SVR effects over GEV and diagnostic accuracy of non-invasive criteria after SVR. METHODS: HCV-cirrhotic patients receiving DAAs and baseline endoscopic evaluation were included (November 2014-October 2015). GEV were classified as low risk (LR-GEV) (< 5 mm) or high risk (HR-GEV) (≥ 5 mm or with risk signs). Transient elastography (TE) and endoscopy were performed during follow-up. RESULTS: SVR was achieved in 230 (93.1%) of 247 included patients, 151 (65.7%) with endoscopic follow-up. Among 64/151 (42.4%) patients without baseline GEV, 8 (12.5%) developed GEV after SVR. Among 50/151 (33.1%) with baseline LR-GEV, 12 (24%) developed HR-GEV. Patients with GEV progression showed TE ≥ 25 kPa before treatment (64.7%) or ≥ 20 kPa after SVR (66.7%). Only 6% of patients without GEV and LSM < 25 kPa before treatment, and 10% of those with baseline LSM < 25 kPa and LSM < 20 kPa after SVR showed GEV progression after 36 months. The negative predictive value of Baveno and expanded-Baveno criteria to exclude HR-GEV was maintained after SVR (100% and 90.7%, respectively). CONCLUSIONS: HCV-cirrhotic patients can develop HR-GEV after SVR. Surveillance is especially recommended in those with GEV before antiviral treatment. Baveno and expanded-Baveno criteria can be safely applied after SVR. https://clinicaltrials.gov: NCT02758509.

Preferred Music Listening Intervention in Nursing Home Residents with Cognitive Impairment: A Randomized Intervention Study.

BACKGROUND: The current trend in addressing symptoms of dementia comprises non-pharmacological strategies such as music interventions for the management and improvement of cognitive function, memory, agitation, depression, or anxiety. OBJECTIVE: To determine the impact of a preferred music listening group intervention upon the functional, cognitive, and emotional dimensions in nursing home residents. METHODS: A randomized intervention study was carried out. The study was conducted from June to August 2015, and involved a preferred music listening group intervention lasting 60 minutes, 5 days/week during 8 weeks. A total of 119 adults aged ≥65 years, with annual permanent residence in the nursing home (Málaga, Spain) were included in the study. 47 (39.5%) subjects were randomized to the music group intervention. The nurses and physiotherapists were blinded to the assessments. RESULTS: The sample had a mean age of 80.52 (SD7.44) years, with female predominance. The subjects presented dependency in Barthel, and cognitive impairment as determined by the MMSE. The Tinetti scores yielded fall risk and depression as evidenced by the Yesavage scale. The Cornell scores evidenced no depression in elderly people with dementia. Following the intervention, function improved significantly with a medium effect size, as did emotional state, with a large effect size. Cognitive function was seen to worsen in the control group, but remained stable in the intervention group, with a large effect size. CONCLUSIONS: A preferred music listening group intervention among elderly people in nursing homes is effective, resulting in improvements in functional and emotional condition.

Concordancias en la intensidad intervención PADES con APS y ESP: los índices kappa son buenos o muy buenos (>0,80) a nivel global, tanto con APS (kappa 0,92, intervalo de confianza del 95%: 0,89-0,95) como con ESP (kappa 0,83, intervalo de confianza del 95%: 0,78-0,87). Esta elevada concordancia incluso mejora con APS en la fase retrospectiva y se mantiene también y es homogénea cuando se analiza según la tipología y la clasificación pronóstica del paciente. Solo con ESP existen diferencias entre categorías, con p < 0,0001 para todos los kappas presentados. CONCLUSIÓN: La alta concordancia entre observadores sobre el grado de intervención del equipo de soporte según el nivel de complejidad detectado indica que el modelo explorado resulta adecuado como instrumento para la gestión y derivación interniveles de casos complejos, independientemente de la tipología clínica (oncológica o no) y de la situación pronóstica del paciente

OBJECTIVE: To ascertain the probable validity of a comprehensive complexity care model in the management and referral of complex cases by studying the agreement between complexities observed from different levels of care in complex chronic patients, advanced chronic patients and at the end of life, using this model as a tool. METHODS: Source: PADES database (demographic and descriptive data) and opinion of the PARTICIPANTS: PARTICIPANTS: the 3 referring (participating) professionals of each case (Primary Health Care [APS], Palliative Care Support Team [PADES], Specialist [ESP]). Variables: age, sex, patient typology (oncological, non-oncological), evolutionary or prognostic classification (chronic complex patient [PCC, advanced [PCA], end of life [PFV]). Model application: 1) detected complexity: clinical, psychoemotional, socio-familial, spiritual, ethical, and related to death; 2) degree of detected complexity: the highest complexity level achieved in the evaluated areas and 3) PADES intervention proposal: low complexity: occasional attention, medium: shared caring; high complexity: intense attention).complexity detected and intensity of PADES intervention in each case according to APS, PADES, ESP: agreement analysis. Study: transversal observational in 2 phases (prospective and retrospective). Statisticians: Cohen's kappa index and χ2 (kappa comparison). Analysis: IBM SPSS v.23 and Epidat v.4.2. RESULTS: The study encompassed 500 patients -prospective phase 248 and retrospective 252-, 54.3% women and 64.8%≥80 years. A 26.8% oncological, and 51.8% PCC, 26.4% PCA and 21.8% PFV.complexity detected: medium/high, with an average of 3 areas affected by case (mainly clinical, psychoemotional, socio-familial, ethical). Agreement in the intervention intensity PADES with APS and ESP: kappa indices are good or very good (>0.80) at a global level, with both APS (kappa 0.92, 95% confidence interval: 0.89-0.95) as with ESP (kappa 0.83, 95% confidence interval: 0.78-0.87). This high agreement even improves with APS in the retrospective phase and is also maintained and is homogeneous when analyzed according to the typology and the prognostic classification of the patient. Only with ESP are there differences between categories, with p < 0,0001 for all kappa presented. CONCLUSIONS: The highest agreement among observers in relation to the degree of support teams' intervention according to the level of detected complexity suggests that this explored complexity model is adequate for the management and referral of complex cases, irrespective of the clinical typology (oncological or otherwise) and the patient's prognosis

Direct-acting antivirals are effective and safe in HCV/HIV-coinfected liver transplant recipients who experience recurrence of hepatitis C: A prospective nationwide cohort study.

Direct-acting antivirals have proved to be highly efficacious and safe in monoinfected liver transplant (LT) recipients who experience recurrence of hepatitis C virus (HCV) infection. However, there is a lack of data on effectiveness and tolerability of these regimens in HCV/HIV-coinfected patients who experience recurrence of HCV infection after LT. In this prospective, multicenter cohort study, the outcomes of 47 HCV/HIV-coinfected LT patients who received DAA therapy (with or without ribavirin [RBV]) were compared with those of a matched cohort of 148 HCV-monoinfected LT recipients who received similar treatment. Baseline characteristics were similar in both groups. HCV/HIV-coinfected patients had a median (IQR) CD4 T-cell count of 366 (256-467) cells/µL. HIV-RNA was <50 copies/mL in 96% of patients. The DAA regimens administered were SOF + LDV ± RBV (34%), SOF + SMV ± RBV (31%), SOF + DCV ± RBV (27%), SMV + DCV ± RBV (5%), and 3D (3%), with no differences between the groups. Treatment was well tolerated in both groups. Rates of SVR (negative serum HCV-RNA at 12 weeks after the end of treatment) were high and similar for coinfected and monoinfected patients (95% and 94%, respectively; P = .239). Albeit not significant, a trend toward lower SVR rates among patients with advanced fibrosis (P = .093) and genotype 4 (P = .088) was observed. In conclusion, interferon-free regimens with DAAs for post-LT recurrence of HCV infection in HIV-infected individuals were highly effective and well tolerated, with results comparable to those of HCV-monoinfected patients.

CD24 Expression Is Increased in 5-Fluorouracil-Treated Esophageal Adenocarcinoma Cells.

The cancer stem cell (CSC) model suggests that there are subsets of cells within a tumor with increased proliferation and self-renewal capacity, which play a key role in therapeutic resistance. The importance of cyclooxygenase-2 (COX-2) in carcinogenesis has been previously established and the use of COX-2 inhibitors as celecoxib has been shown to exert antitumor effects. The present study investigated whether treatment of esophageal adenocarcinoma (EAC) cells with 5-fluorouracil (5-FU) or the growth of tumor spheres increased the proportion of CSCs and also if treatment with celecoxib was able to reduce the putative CSC markers in this tumor. OE19 and OE33 EAC cells surviving 5-FU exposure exhibited an increase in CSC markers CD24 and ABCG2 and also an increased resistance to apoptosis. EAC cell lines had the capacity to form multiple spheres displaying typical CSC functionalities such as self-renewal and increased CD24 levels. In addition, after the induction of differentiation, cancer cells reached levels of CD24 similar to those observed in the parental cells. Treatment with celecoxib alone or in combination with 5-FU also resulted in a reduction of CD24 expression. Moreover, celecoxib inhibited the growth of tumor spheres. These findings showing a reduction in CSC markers induced by celecoxib suggest that the COX-2 inhibitor might be a candidate for combined chemotherapy in the treatment of EAC. However, additional clinical and experimental studies are needed.

Real-World Multicenter Experience of Immunosuppression Minimization Among 661 Liver Transplant Recipients.

BACKGROUND Long-term morbidity and mortality in liver transplant recipients is frequently secondary to immunosuppression toxicity. However, data are scarce regarding immunosuppression minimization in clinical practice. MATERIAL AND METHODS In this cross-sectional, multicenter study, we reviewed the indications of immunosuppression minimization (defined as tacrolimus levels below 5 ng/mL or cyclosporine levels below 50 ng/mL) among 661 liver transplant recipients, as well as associated factors and the effect on renal function. RESULTS Fifty-three percent of the patients received minimized immunosuppression. The median time from transplantation to minimization was 32 months. The most frequent indications were renal insufficiency (49%), cardiovascular risk (19%), de novo malignancy (8%), and cardiovascular disease (7%). The factors associated with minimization were older age at transplantation, longer post-transplant follow-up, pre-transplant diabetes mellitus and renal dysfunction, and the hospital where the patients were being followed. The patients who were minimized because of renal insufficiency had a significant improvement in renal function (decrease of the median serum creatinine level, from 1.50 to 1.34 mg/dL; P=0.004). Renal function significantly improved in patients minimized for other indications, too. In the long term, glomerular filtration rate significantly decreased in non-minimized patients and remained stable in minimized patients. CONCLUSIONS Immunosuppression minimization is frequently undertaken in long-term liver transplant recipients, mainly for renal insufficiency. Substantial variability exists regarding the use of IS minimization among centers.

Human immunodeficiency virus-infected liver transplant recipients with incidental hepatocellular carcinoma: A prospective multicenter nationwide cohort study.

There is a lack of data on incidental hepatocellular carcinoma (iHCC) in the setting of liver transplantation (LT) in human immunodeficiency virus (HIV)-infected patients. This study aims to describe the frequency, histopathological characteristics, and outcomes of HIV+ LT recipients with iHCC from a Spanish multicenter cohort in comparison with a matched cohort of LT patients without HIV infection. A total of 15 (6%) out of 271 patients with HIV infection who received LT in Spain from 2002 to 2012 and 38 (5%) out of the 811 HIV- counterparts presented iHCC in liver explants (P = 0.58). Patients with iHCC constitute the present study population. All patients also had hepatitis C virus (HCV)-related cirrhosis. There were no significant differences in histopathological features of iHCC between the 2 groups. Most patients showed a small number and size of tumoral nodules, and few patients had satellite nodules, microvascular invasion, or poorly differentiated tumors. After a median follow-up of 49 months, no patient developed hepatocellular carcinoma (HCC) recurrence after LT. HIV+ LT recipients tended to have lower survival than their HIV- counterparts at 1 (73% versus 92%), 3 (67% versus 84%), and 5 years (50% versus 80%; P = 0.06). There was also a trend to a higher frequency of HCV recurrence as a cause of death in the former (33% versus 10%; P = 0.097). In conclusion, among LT recipients for HCV-related cirrhosis, the incidence and histopathological features of iHCC in HIV+ and HIV- patients were similar. However, post-LT survival was lower in HIV+ patients probably because of a more aggressive HCV recurrence. Liver Transplantation 23 645-651 2017 AASLD.

Controlling Diabetes After Liver Transplantation: Room for Improvement.

BACKGROUND: Diabetes mellitus is a chronic illness with great impact on long-term outcome after liver transplantation (LT). Despite this, the current level of glycemic control and quality of screening strategies for diabetes-associated conditions that are being provided to liver transplant recipients with diabetes have not yet been assessed. METHODS: We performed a cross-sectional, multicenter study that included 344 liver transplant recipients and examined the level of glycemic control and its associated factors, as well as the quality of screening strategies for diabetes-associated conditions. RESULTS: Seventy-five patients (21.8%) suffered from diabetes before transplantation, and 82 (23.8%) developed diabetes mellitus after transplantation. Adequate glycemic control (HbA1c < 7%) was achieved in 66.7% of the patients. Forty-eight percent of patients underwent regular screening for retinopathy, 47.1% for nephropathy, 4.5% for neuropathy, and 5.7% for foot ulcers. Diabetes was associated with higher frequency of cardiovascular disease and dyslipidemia both before and after LT. Multivariate analysis revealed association between poor glycemic control and arterial hypertension, presence of diabetes before transplantation, elevated GGT, and insulin use. CONCLUSIONS: Glycemic control was inadequate in 33.3% of LT recipients with diabetes, and screening protocols for diabetes-associated conditions did not meet the standards for medical care set by the American Diabetes Association in any of the participating centers. Consequently, this study reveals a clear deficiency in the quality of diabetes care provided to patients after LT and, hence, we predict that future progress in this area will have a significant impact on medium-term to long-term outcome of these patients.
