RESUMEN

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.

RESUMEN

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. The objective of this study was 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 was performed, which included HCV-monoinfected patients with F3 fibrosis determined by transient elastography who achieved SVR between 2015 and 2022, 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: two hundred and nineteen patients were included in the study (65.3 % males, median age 57 years), and 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.

RESUMEN

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.

RESUMEN

The Spanish Association for the Study of the Liver (AEEH) is convinced that the elimination of hepatitis C virus (HCV) in Spain is possible as long as we are able to use the resources and tools necessary for it. This document reflects the position of the AEEH regarding the elimination of HCV, establishing a wide range of recommendations that can be grouped into five categories: 1) Screening of HCV according to age, of the existence of classic acquisition risk factors of infection, active search of previously diagnosed patients and development of microelimination strategies in vulnerable populations; 2) Simplification of HCV diagnosis (one-step diagnosis and diagnosis at the point of patient care); 3) Simplification of patient treatment and improvement of care circuits; 4) Health policy measures, and, finally, 5) Establishment of HCV elimination indicators.

RESUMEN

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.

RESUMEN

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.

RESUMEN

UNLABELLED: The impact of human immunodeficiency virus (HIV) infection on patients undergoing liver transplantation (LT) for hepatocellular carcinoma (HCC) is uncertain. This study aimed to assess the outcome of a prospective Spanish nationwide cohort of HIV-infected patients undergoing LT for HCC (2002-2014). These patients were matched (age, gender, year of LT, center, and hepatitis C virus (HCV) or hepatitis B virus infection) with non-HIV-infected controls (1:3 ratio). Patients with incidental HCC were excluded. Seventy-four HIV-infected patients and 222 non-HIV-infected patients were included. All patients had cirrhosis, mostly due to HCV infection (92%). HIV-infected patients were younger (47 versus 51 years) and had undetectable HCV RNA at LT (19% versus 9%) more frequently than non-HIV-infected patients. No significant differences were detected between HIV-infected and non-HIV-infected recipients in the radiological characteristics of HCC at enlisting or in the histopathological findings for HCC in the explanted liver. Survival at 1, 3, and 5 years for HIV-infected versus non-HIV-infected patients was 88% versus 90%, 78% versus 78%, and 67% versus 73% (P = 0.779), respectively. HCV infection (hazard ratio = 7.90, 95% confidence interval 1.07-56.82) and maximum nodule diameter >3 cm in the explanted liver (hazard ratio = 1.72, 95% confidence interval 1.02-2.89) were independently associated with mortality in the whole series. HCC recurred in 12 HIV-infected patients (16%) and 32 non-HIV-infected patients (14%), with a probability of 4% versus 5% at 1 year, 18% versus 12% at 3 years, and 20% versus 19% at 5 years (P = 0.904). Microscopic vascular invasion (hazard ratio = 3.40, 95% confidence interval 1.34-8.64) was the only factor independently associated with HCC recurrence. CONCLUSIONS: HIV infection had no impact on recurrence of HCC or survival after LT. Our results support the indication of LT in HIV-infected patients with HCC.

RESUMEN

Appropriate post-transplant immunosuppressive regimens that avoid acute rejection, while reducing risk of viral reactivation, have been sought, but remain a chimera. Recent evidence suggesting potential regulatory and antiviral effects of mammalian target of rapamycin inhibitors (mTORi) is of great interest. Although the concept of an immunosuppressive drug with antiviral properties is not new, little effort has been made to put the evidence together to assess the management of immunosuppressive therapy in the presence of a viral infection. This review was developed to gather the evidence on antiviral activity of the mTORi against the viruses that most commonly reactivate in adult solid organ recipients: cytomegalovirus (CMV), polyomavirus, Epstein-Barr virus (EBV), human herpesvirus 8 (HHV8), and hepatitis C virus (HCV). A rapid review methodology and evaluation of quality and consistency of evidence based on the GRADE system was used. The existing literature was variable in nature, although indicating a potential advantage of mTORi in CMV, polyomavirus, and HHV8 infection, and a most doubtful relation with EBV and HCV infection. Several recommendations about the management of these infections are presented that can change certain current patterns of immunosuppression and help to improve the prognosis of the direct and indirect effects of viral infection in solid organ recipients.

RESUMEN

A national, multicenter, retrospective study was conducted to assess the results obtained for liver transplant recipients with conversion to everolimus in daily practice. The study included 477 recipients (481 transplantations). Indications for conversion to everolimus were renal dysfunction (32.6% of cases), hepatocellular carcinoma (HCC; 30.2%; prophylactic treatment for 68.9%), and de novo malignancy (29.7%). The median time from transplantation to conversion to everolimus was 68.7 months for de novo malignancy, 23.8 months for renal dysfunction, and 7.1 months for HCC and other indications. During the first year of treatment, mean everolimus trough levels were 5.4 (standard deviation [SD], 2.7) ng/mL and doses remained stable (1.5 mg/day) from the first month after conversion. An everolimus monotherapy regimen was followed by 28.5% of patients at 12 months. Patients with renal dysfunction showed a glomerular filtration rate (4-variable Modification of Diet in Renal Disease) increase of 10.9 mL (baseline mean, 45.8 [SD, 25.3] versus 57.6 [SD, 27.6] mL/minute/1.73 m(2) ) at 3 months after everolimus initiation (P < 0.001), and 6.8 mL at 12 months. Improvement in renal function was higher in patients with early conversion (<1 year). Adverse events were the primary reason for discontinuation in 11.2% of cases. The probability of survival at 3 years after conversion to everolimus was 83.0%, 71.1%, and 59.5% for the renal dysfunction, de novo malignancy, and HCC groups, respectively. Everolimus is a viable option for the treatment of renal dysfunction, and earlier conversion is associated with better recovery of renal function. Prospective studies are needed to confirm advantages in patients with malignancy.

RESUMEN

The aim of this study was to evaluate the impact of a steroid-free regimen with tacrolimus and mycophenolate mofetil (modified therapy) vs. a standard regimen of tacrolimus and steroids on the cardiovascular risk score of liver transplant recipients. Patients who received a liver transplant were randomized to a modified therapy (n = 58) or a standard regimen (n = 59). Both groups were balanced at baseline, except for a higher prevalence of diabetes mellitus (DM) (p < 0.01) and a higher serum creatinine concentration (p < 0.05) in the modified therapy group. After 12 months, the prevalence of new-onset DM, arterial hypertension, hypercholesterolemia, hypertriglyceridemia, and changes in cardiovascular risk factors was similar in both groups. The increase in serum creatinine (mg/dL) compared to baseline at one yr post-transplantation was numerically lower in the modified therapy group (0.22 ± 0.42) than in the standard regimen group (0.41 ± 0.67) (p = 0.068). Although estimated cardiovascular risk score did not vary significantly compared to baseline in either group, there was a slight reduction in the modified regimen (-0.27 ± 2.87) vs. a mild increase (0.17 ± 2.94) in the standard regimen (p = 0.566). In conclusion, a steroid-free regimen with tacrolimus and mycophenolate mofetil was associated with a trend toward better preservation of kidney function and reduction of cardiovascular risk score.

RESUMEN

INTRODUCTION: GIDEON is a non-interventional, prospective, international study that evaluated the safety of sorafenib in patients with unresectable hepatocellular carcinoma (HCC) in daily clinical practice, including Child-Pugh B patients. OBJECTIVES: To analyze data collected in Spain on the safety and efficacy of sorafenib and treatment patterns. METHODS: Data were collected during follow-up on demographic and disease characteristics, the initial dose used, treatment-emergent adverse events (AEs) and dose modifications. Overall survival was evaluated, as well as time to disease progression. Efficacy and safety were analyzed according to the Child-Pugh classification and the initial dose. RESULTS: We included 143 patients from 19 Spanish hospitals. A total of 24.5% of the patients were Child-Pugh B. An initial dose of 400 mg/12 h was used in 90.9% of patients. In Child-Pugh A patients, dose modifications occurred more frequently and the treatment duration was longer. The incidence of AEs and drug-related AEs were similar in Child-Pugh A and B patients, although serious AEs were more frequent in Child-Pugh B patients. The most common AEs were diarrhea, fatigue and hand-foot skin reactions. The median overall survival was 384 days and was higher in Child-Pugh A patients (593 vs. 211 days in Child-Pugh B). The median time to disease progression was 177 days, similar in both subgroups. CONCLUSION: The safety profile of sorafenib in Spanish patients with unresectable HCC is independent of liver function. Child-Pugh status does not seem to influence the approach to sorafenib dosage or time to progression but does seem to be a strong prognostic factor for survival.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.
