RESUMEN
BACKGROUND & AIMS: Idiosyncratic drug-induced liver injury (DILI) is a complex and unpredictable event caused by drugs, and herbal or dietary supplements. Early identification of human hepatotoxicity at preclinical stages remains a major challenge, in which the selection of validated in vitro systems and test drugs has a significant impact. In this systematic review, we analyzed the compounds used in hepatotoxicity assays and established a list of DILI-positive and -negative control drugs for validation of in vitro models of DILI, supported by literature and clinical evidence and endorsed by an expert committee from the COST Action ProEuroDILI Network (CA17112). METHODS: Following 2020 PRISMA guidelines, original research articles focusing on DILI which used in vitro human models and performed at least one hepatotoxicity assay with positive and negative control compounds, were included. Bias of the studies was assessed by a modified 'Toxicological Data Reliability Assessment Tool'. RESULTS: A total of 51 studies (out of 2,936) met the inclusion criteria, with 30 categorized as reliable without restrictions. Although there was a broad consensus on positive compounds, the selection of negative compounds lacked clarity. 2D monoculture, short exposure times and cytotoxicity endpoints were the most tested, although there was no consensus on drug concentrations. CONCLUSIONS: Extensive analysis highlighted the lack of agreement on control compounds for in vitro DILI assessment. Following comprehensive in vitro and clinical data analysis together with input from the expert committee, an evidence-based consensus-driven list of 10 positive and negative control drugs for validation of in vitro models of DILI is proposed. IMPACT AND IMPLICATIONS: Prediction of human toxicity early in the drug development process remains a major challenge, necessitating the development of more physiologically relevant liver models and careful selection of drug-induced liver injury (DILI)-positive and -negative control drugs to better predict the risk of DILI associated with new drug candidates. Thus, this systematic study has crucial implications for standardizing the validation of new in vitro models of DILI. By establishing a consensus-driven list of positive and negative control drugs, the study provides a scientifically justified framework for enhancing the consistency of preclinical testing, thereby addressing a significant challenge in early hepatotoxicity identification. Practically, these findings can guide researchers in evaluating safety profiles of new drugs, refining in vitro models, and informing regulatory agencies on potential improvements to regulatory guidelines, ensuring a more systematic and efficient approach to drug safety assessment.
RESUMEN
BACKGROUND & AIMS: Latin America is a region of great interest for studying the clinical presentation of idiosyncratic drug-induced liver injury (DILI). A comprehensive analysis of patients enrolled into the LATINDILI Network over a decade is presented. METHODS: Demographics, clinical presentation, histological findings and outcome of prospectively recruited DILI cases in the LATINDILI Network were analyzed. Suspected culprit drugs were classified according to the Anatomical Therapeutic Chemical classification. Causality was assessed using the Roussel Uclaf Causality Assessment Method (RUCAM) scale. RESULTS: Overall, 468 idiosyncratic DILI cases were analyzed (62% women; mean age, 49 years). Hepatocellular injury predominated (62%); jaundice was present in 60% of patients, and 42% were hospitalized. Of the cases, 4.1% had a fatal outcome, and 24 patients (12%) developed chronic DILI. The most common drug classes were systemic anti-infectives (31%), musculoskeletal agents (12%), antineoplastic and immunomodulating agents (11%), and herbal and dietary supplements (9%). Notably, none of the patients with DILI due to antibacterials or immunosuppressants had a fatal outcome. In fact, Hy's law showed to have drug-specific predictive value, with anti-tuberculosis drugs, nimesulide, and herbal and dietary supplements associated with the worst outcome, whereas DILI caused by amoxicillin-clavulanate, nitrofurantoin, and diclofenac, which fulfilled Hy's law, did not have a fatal outcome. CONCLUSION: Features of DILI in Latin America are comparable to other prospective registries. However, the pattern of drugs responsible for DILI differs. An increasing incidence of herbal and dietary supplements, with high mortality rate, and likewise, nimesulide and nitrofurantoin, was noted. Thus, public health policies should raise awareness of the potential adverse effects of these compounds.
RESUMEN
Drug-induced liver injury (DILI) is a challenging liver disorder for hepatologists. We aimed to assess the pattern and causes of DILI in a tertiary hospital. We registered prospectively all patients referred with suspicion of DILI from 2018 to 2023. A total of 106 patients fulfilled the diagnostic criteria (30 caused by paracetamol were excluded; total number 76). The pattern of liver injury was hepatocellular in 55 (72%). Drugs causing DILI were antineoplastic (26%), antibiotics (24%), analgesics (12%), and recreational drugs (9%). Regarding clinical outcomes, 39 (51%) required hospitalization and 7 (9%) underwent a liver transplantation or died from acute liver injury. We identified 126 additional patients with DILI due to immune check-point inhibitors who were not referred to a liver disease specialist. Antineoplastic drugs have become the first cause of DILI in hospitals. A multidisciplinary approach and specific educational tools to increase DILI awareness are needed among different specialists.

The elderly demographic is the fastest-growing segment of the world's population and is projected to exceed 1.5 billion people by 2050. With multimorbidity, polypharmacy, susceptibility to drug-drug interactions, and frailty as distinct risk factors, elderly patients are especially vulnerable to developing potentially life-threatening safety events such as serious forms of drug-induced liver injury (DILI). It has been a longstanding shortcoming that elderly individuals are often a vulnerable population underrepresented in clinical trials. As such, an improved understanding of DILI in the elderly is a high-priority, unmet need. This challenge is underscored by recent documents put forward by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) that encourage data collection in the elderly and recommend improved practices that will facilitate a more inclusive approach. To establish what is already known about DILI in the elderly and pinpoint key gaps of knowledge in this arena, a working definition of "elderly" is required that accounts for both chronologic and biologic ages and varying states of frailty. In addition, it is critical to characterize the biological role of aging on liver function, as well as the different epidemiological factors such as polypharmacy and inappropriate prescribing that are common practices. While data may not show that elderly people are more susceptible to DILI, DILI due to specific drugs might be more common in this population. Improved characterization of DILI in the elderly may enhance diagnostic and prognostic capabilities and improve the way in which liver safety is monitored during clinical trials. This summary of the published literature provides a framework to understand and evaluate the risk of DILI in the elderly. Consensus statements and recommendations can help to optimize medical care and catalyze collaborations between academic clinicians, drug manufacturers, and regulatory scientists to enable the generation of high-quality research data relevant to the elderly population.

Background: Since the introduction of direct-acting antivirals, thousands of chronic hepatitis C patients have been successfully treated. However, vulnerable populations have a higher prevalence of hepatitis C virus (HCV) infection and face barriers that impede their access to antivirals. We carried out an HCV microelimination program focused on vulnerable population groups in Malaga. Methods: People in drug addiction treatment centers and homeless shelters in Malaga who participated in the program between October 2020 and October 2021 were included. After providing participants with educational information on HCV, a dry drop test (DDT) was used to collect blood for subsequent screening for HCV infection. The participants who were diagnosed with HCV infection were scheduled for comprehensive healthcare assessments, including blood tests, ultrasonography, elastography, and the prescription of antivirals, all conducted in a single hospital visit. Sustained viral response (SVR) was analysed 12 weeks after end of treatment. Results: Of the 417 persons invited to participate, 271 (65%) agreed to participate in the program. These participants were screened for HCV infection and 28 of them were diagnosed with HCV infection (10%). These hepatitis C-infected patients had a mean age of 53 ± 9 years; 86% were males and 93% were or had been drug users. Among 23 patients with HCV infection, HCV genotype 1a predominated (74%). Medical exams showed that 19% (4/21) had advanced fibrosis (F3-4), and 5% (1/21) had portal hypertension. Finally, 23 infected patients received treatment with glecaprevir/pibrentasvir or sofosbuvir/velpatasvir and SVR was confirmed in 22 patients (96%). Conclusions: Drug users and homeless people have a higher prevalence of HCV infection than the general population. The microelimination program with educational activity and screening tools achieved a high participation rate, easy healthcare access, and a high rate of SVR despite the SARS-CoV-2 pandemic.
RESUMEN
BACKGROUND: Sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) is the recommended rescue therapy for patients with chronic hepatitis C infection who fail direct-acting antivirals (DAAs). Data are limited on the effectiveness of this treatment after the current first-line therapies. Our aim was to analyse the effectiveness and safety of SOF/VEL/VOX among patients failing sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB). METHODS: Retrospective multicentre study (26 Spanish hospitals), including chronic hepatitis C patients unsuccessfully treated with SOF/VEL or GLE/PIB, and retreated with SOF/VEL/VOX ± ribavirin for 12 weeks between December 2017 and December 2022. RESULTS: In total, 142 patients included: 100 (70.4%) had failed SOF/VEL and 42 (29.6%) GLE/PIB. Patients were mainly men (84.5%), White (93.9%), with hepatitis C virus genotype (GT) 3 (49.6%) and 47.2% had liver cirrhosis. Sustained virological response (SVR) was evaluated in 132 patients who completed SOF/VEL/VOX and were followed 12 weeks after end of treatment; 117 (88.6%) achieved SVR. There were no significant differences in SVR rates according to initial DAA treatment (SOF/VEL 87.9% vs. GLE/PIB 90.2%, p = 0.8), cirrhosis (no cirrhosis 90% vs. cirrhosis 87.1%, p = 0.6) or GT3 infection (non-GT3 91.9% vs. GT3 85.5%, p = 0.3). However, when considering the concurrent presence of SOF/VEL treatment, cirrhosis and GT3 infection, SVR rates dropped to 82.8%. Ribavirin was added in 8 (6%) patients, all achieved SVR. CONCLUSION: SOF/VEL/VOX is an effective rescue therapy for failures to SOF/VEL or GLE/PIB, with an SVR of 88.6%. Factors previously linked to lower SVR rates, such as GT3 infection, cirrhosis and first-line therapy with SOF/VEL were not associated with lower SVRs.

AIM: We aimed to assess the role of FGF21 in metabolic dysfunction-associated steatotic liver disease (MASLD) at a multi-scale level. METHODS: We used human MASLD pathology samples for FGF21 gene expression analyses (qPCR and RNAseq), serum to measure circulating FGF21 levels and DNA for genotyping the FGF21 rs838133 variant in both estimation and validation cohorts. A hepatocyte-derived cell line was exposed to free fatty acids at different timepoints. Finally, C57BL/6J mice were fed a high-fat and choline-deficient diet (CDA-HFD) for 16 weeks to assess hepatic FGF21 protein expression and FGF21 levels by ELISA. RESULTS: A significant upregulation in FGF21 mRNA expression was observed in the liver analysed by both qPCR (fold change 5.32 ± 5.25 vs. 0.59 ± 0.66; p = 0.017) and RNA-Seq (3.5 fold; FDR: 0.006; p < 0.0001) in MASLD patients vs. controls. Circulating levels of FGF21 were increased in patients with steatohepatitis vs. bland steatosis (386.6 ± 328.9 vs. 297.9 ± 231.5 pg/mL; p = 0.009). Besides, sex, age, A-allele from FGF21, GG genotype from PNPLA3, ALT, type 2 diabetes mellitus and BMI were independently associated with MASH and significant fibrosis in both estimation and validation cohorts. In vitro exposure of Huh7.5 cells to high concentrations of free fatty acids (FFAs) resulted in overexpression of FGF21 (p < 0.001). Finally, Circulating FGF21 levels and hepatic FGF21 expression were found to be significantly increased (p < 0.001) in animals under CDA-HFD. CONCLUSIONS: Hepatic and circulating FGF21 expression was increased in MASH patients, in Huh7.5 cells under FFAs and in CDA-HFD animals. The A-allele from the rs838133 variant was also associated with an increased risk of steatohepatitis and significant and advanced fibrosis in MASLD patients.
RESUMEN
Drug-induced liver injury (DILI) is a significant cause of acute liver failure (ALF) and liver transplantation in the Western world. Acetaminophen (APAP) overdose is a main contributor of DILI, leading to hepatocyte cell death through necrosis. Here, we identified that neddylation, an essential post-translational modification involved in the mitochondria function, was upregulated in liver biopsies from patients with APAP-induced liver injury (AILI) and in mice treated with an APAP overdose. MLN4924, an inhibitor of the neuronal precursor cell-expressed developmentally downregulated protein 8 (NEDD8)-activating enzyme (NAE-1), ameliorated necrosis and boosted liver regeneration in AILI. To understand how neddylation interferes in AILI, whole-body biotinylated NEDD8 (bioNEDD8) and ubiquitin (bioUB) transgenic mice were investigated under APAP overdose with and without MLN4924. The cytidine diphosphate diacylglycerol (CDP-DAG) synthase TAM41, responsible for producing cardiolipin essential for mitochondrial activity, was found modulated under AILI and restored its levels by inhibiting neddylation. Understanding this ubiquitin-like crosstalk in AILI is essential for developing promising targeted inhibitors for DILI treatment.

BACKGROUND: MASLD can manifest as hepatocellular damage, which can result in mild elevation of aminotransferases. However, in some patients, MASLD presents with cholestatic pattern. OBJECTIVE: To assess the impact of the biochemical pattern on the natural course of MASLD, including liver damage in histology, the accuracy of non-invasive tests(NITs), and prognosis. METHODS: Multicenter study enrolling 2156 patients with biopsy-proven MASLD, who were classified based on their[ALT/ULN)]/[(ALP/ULN)] levels at the time of biopsy: (a) hepatocellular pattern(H), > 5; (b) mixed pattern(M),2-5; (c) cholestatic pattern(C), < 2. OUTCOMES: (a) histological evaluation of the single components of NAS, MASH, and fibrosis; (b) NITs and transient elastography assessing advanced fibrosis; (c) prognosis determined by the appearance of decompensated cirrhosis and death. RESULTS: Out of the 2156 patients, 22.9% exhibited the H-pattern, whilst 31.7% exhibited the C-pattern. Severe steatosis, ballooning, lobular inflammation, and MASH (56.4% H vs. 41.9% M vs. 31.9% C) were more common in H-pattern (p = 0.0001),whilst C-pattern was linked to cirrhosis (5.8% H vs. 5.6% M vs. 10.9% C; p = 0.0001). FIB-4(0.74(95% CI 0.69-0.79) vs. 0.83 (95% CI 0.80-0.85); p = 0.005) and Hepamet Fibrosis Score(0.77 (95% CI 0.69-0.85) vs. 0.84 (95% CI 0.80-0.87); p = 0.044)exhibited lower AUROCs in the H-pattern. The C-pattern[HR 2.37 (95% CI 1.12-5.02); p = 0.024], along with age, diabetes, and cirrhosis were independently associated with mortality. Most patients maintained their initial biochemical pattern during the second evaluation. CONCLUSIONS: The H-pattern exhibited greater necro-inflammation in the histology than the C-pattern, whereas the latter showed more cirrhosis. The accuracy of NITs in detecting fibrosis was decreased in H-pattern. The occurrence of decompensated events and mortality was predominant in C-pattern. Therefore, identifying MASLD phenotypes based on the biochemical presentation could be relevant for clinical practice.

Chronic liver disease (CLD) is a leading health problem impacting the quality of life globally. China shares a major global burden of CLD-including alcoholic liver disease, nonalcoholic fatty liver disease/metabolic dysfunction-associated fatty liver disease, and drug-induced liver injury, except for chronic viral hepatitis. Several exogenous toxins or endogenous metabolic insults trigger hepatic pathology toward steatosis, inflammation, and fibrosis, which, if left untreated, may culminate in liver cirrhosis. Oxidative stress is a common pathomechanism underlying all phenotypes of toxic liver injury; thus, these may be brought under a unified entity, viz. toxic liver disease (TLD). Therefore, a common strategy to treat TLD is to use antioxidants as hepatoprotective agents. The cornerstone for treating fatty liver disease is lifestyle modification, diet, exercise, and behavioral therapy, along with the limited use of pharmacological agents. Available preclinical and clinical evidence indicates that silymarin is a hepatoprotective agent with established antioxidant, anti-inflammatory, antifibrotic effects. An international expert panel of clinicians was convened to discuss combining alcoholic liver disease, nonalcoholic fatty liver disease/metabolic dysfunction-associated fatty liver disease, drug-induced liver injury, and liver cirrhosis under the single definition of TLD, based on the shared pathologic mechanism of oxidative stress. The panel highlighted the significance of silymarin as an antioxidant treatment for TLD.
RESUMEN
Background and objective: The emergence of highly tolerable, effective, and shorter duration direct-acting antivirals (DAAs) regimens offers the opportunity to simplify hepatitis C virus management but medical costs are unknown. Thus, we aimed to determine the direct medical costs associated with a combo-simplified strategy (one-step diagnosis and low monitoring) to manage HCV infection within an 8-week glecaprevir/pibrentasvir (GLE/PIB) regimen in clinical practice in Spain. Patients and methods: Healthcare resources and clinical data were collected retrospectively from medical charts of 101 eligible patients at 11 hospitals. Participants were adult, treatment naïve subjects with HCV infection without cirrhosis in whom a combo-simplified strategy with GLE/PIB for 8 weeks were programmed between Apr-2018 and Nov-2018. Results: The GLE/PIB effectiveness was 100% (CI95%: 96.2100%) in the mITT population and 94.1% (CI95%: 87.597.8%) in the ITT population. Three subjects discontinued the combo-simplified strategy prematurely, none of them due to safety reasons. Five subjects reported 8 adverse events, all of mild-moderate intensity. Combo-simplified strategy mean direct costs were 754.35±103.60 compared to 1689.42 and 2007.89 of a theoretical 12-week treatment with 4 or 5 monitoring visits, respectively; and 1370.95 and 1689.42 of a theoretical 8-week with 3 or 4 monitoring visits, respectively. Only 4.9% of the subjects used unexpected health care resources. Conclusions: 8-week treatment with GLE/PIB combined with a combo simplified strategy in real-life offers substantial cost savings without affecting the effectiveness and safety compared to traditional approaches.(AU)
Antecedentes y objetivo: La aparición de regímenes antivirales de acción directa altamente tolerables, eficaces y de corta duración permite simplificar el manejo de la hepatitis C, pero los costes médicos se desconocen. Así, se pretende determinar los costes médicos directos asociados a una estrategia simplificada (diagnóstico en un solo paso y monitorización reducida) para controlar la infección por VHC con un régimen de 8 semanas de glecaprevir/pibrentasvir (GLE/PIB) en la práctica clínica en España. Pacientes y métodos: Los recursos sanitarios y los datos clínicos se recopilaron retrospectivamente de las historias médicas de 101 pacientes elegibles en 11 hospitales. Los participantes fueron sujetos adultos, sin tratamiento previo de la infección por VHC y sin cirrosis, en los que se programó una estrategia combinada simplificada con GLE/PIB durante 8 semanas entre abril y noviembre de 2018. Resultados: La eficacia de GLE/PIB fue del 100% (IC 95% 96,2-100) en la población mITT y del 94,1% (IC 95% 87,5-97,8) en la población ITT. Tres sujetos suspendieron prematuramente la estrategia combinada simplificada, ninguno de ellos por razones de seguridad. Cinco sujetos reportaron 8 acontecimientos adversos de intensidad leve-moderada. Los costes directos fueron de 754,35±103,60 frente a 1.689,42 y 2.007,89 de un tratamiento teórico de 12 semanas con 4 o 5 visitas de monitorización, respectivamente; y 1.370,95 y 1.689,42 de un tratamiento teórico de 8 semanas con 3 o 4 visitas de monitorización, respectivamente. El 4,9% de los sujetos utilizaron recursos de atención médica inesperados. Conclusiones: En la vida real, el tratamiento de 8 semanas con GLE/PIB junto con una estrategia simplificada ofrece ahorros sustanciales de costos, sin afectar la eficacia y seguridad, en comparación con abordajes tradicionales.(AU)

Introduction: The pandemic caused by SARS-CoV-2 has drastically changed the global health landscape. Our objective was to verify if, after the start of the pandemic, there was an increase in in-hospital mortality in patients admitted to a Gastroenterology Service of a 3rd level hospital. Material and methods: The 1039 admissions registered at the Virgen de la Victoria University Hospital in Malaga (Spain) were retrospectively analysed in the period between 1 December 2019 and 30 November 2020 (12 months), which were divided into 4 quarters (pre-wave, first wave, inter-wave and second wave) and mortality and other variables (globally and by disease group) were analysed. Results: No statistically significant differences were observed in terms of overall in-hospital mortality in the different periods. (p 0.23). The greatest burden of disease corresponded to biliopancreatic group and, within them, acute pancreatitis (p 0.04), followed by non-variceal gastrointestinal bleeding. In the second semester, mortality increased in the biliopancreatic group (p 0.01). Patients admitted for gastrointestinal bleeding took longer to request care after the start of the pandemic, especially in the second wave (p 0.03). The same was observed in admissions due to tumours, with the time elapsed until the emergency visit more than double in the second semester, with a consequent increase in mortality (p 0.00). Conclusions: The global in-hospital mortality in a Gastroenterology Service in a 3rd level hospital has not increased with the onset of the SARS-CoV-2 pandemic, however, a higher in-hospital mortality has been recorded in biliopancreatic diseases and digestive tumours diagnosed on an in-patient basis between June and November 2020.(AU)
Introducción:La pandemia ocasionada por el SARS-CoV-2 ha modificado drásticamente el panorama sanitario mundial. Nuestro objetivo fue comprobar si tras el inicio de esta se produjo un aumento en la mortalidad intrahospitalaria en los pacientes ingresados en un servicio de aparato digestivo de un hospital de tercer nivel. Material y métodos: Se analizaron retrospectivamente 1.039 ingresos en el Servicio de Aparato Digestivo del Hospital Universitario Virgen de la Victoria en el periodo comprendido entre el 1 de diciembre de 2019 y el 30 de noviembre de 2020 (12 meses), se dividieron en 4 trimestres (preoleada, primera oleada, interoleada y segunda oleada) y se analizó la mortalidad y otras variables (de forma global y por grupo de enfermedades). Resultados: No se observaron diferencias estadísticamente significativas en cuanto a mortalidad intrahospitalaria global en los diferentes periodos (p=0,23). La enfermedad con mayor predominio fue la biliopancreática y, dentro de ella, las pancreatitis agudas (p=0,04), seguidas del sangrado digestivo no varicoso. En el segundo semestre aumentó la mortalidad en el grupo biliopancreático (p=0,01). Los pacientes que ingresaron por hemorragia digestiva tardaron más en solicitar asistencia tras la pandemia, especialmente en la segunda oleada (p=0,03). Esto mismo se objetivó en los ingresos por tumores, siendo el tiempo transcurrido hasta la consulta a Urgencias mayor del doble en el segundo semestre, con el consecuente aumento en la mortalidad (p=0,00). Conclusiones: La mortalidad global intrahospitalaria en el Servicio de Aparato Digestivo no ha aumentado con la sobrevenida de la pandemia por SARS-CoV-2, si bien se ha registrado una mayor mortalidad intrahospitalaria en las enfermedades biliopancreáticas y los tumores digestivos diagnosticados en régimen de hospitalización entre junio y noviembre de 2020.(AU)

En el año 2016 se detectó en la provincia de Málaga un brote de hepatitis A en pacientes con características epidemiológicas especiales, con un predominio de sujetos del sexo masculino. Presentamos 51 casos de hepatitis A aguda con una media de edad de 35,7 años, el 90% varones, con un 55% de casos que reconocían haber mantenido relaciones sexuales con otros hombres en los últimos dos meses. La mitad de ellos requirieron ingreso hospitalario por coagulopatía significativa en el momento del diagnóstico, sin evolución a fallo fulminante, ni encefalopatía en ningún caso. Cuatro casos presentaban ascitis al diagnóstico. Este brote se suma a otros dos publicados en Reino Unido y Holanda con un número de casos similar y epidemiológicamente muy parecidos, lo cual refuerza la importancia de la vigilancia epidemiológica y la necesidad de vacunación en esta población de riesgo, así como de campañas informativas a la población para prevenir la enfermedad
In 2016, an outbreak of hepatitis A was identified in the Malaga province among patients with specific epidemiological characteristics, which were predominantly males. This is a report of 51 subjects with acute hepatitis A and a mean age of 35.7 years, 90% were male and 55% of cases were men who had had sex with other men within the last two months. Half of them required hospitalization for significant coagulopathy at diagnosis and no cases progressed to fulminant failure or encephalopathy. Four patients had ascites at the time of diagnosis. This outbreak adds to those reported in the United Kingdom and the Netherlands with a similar number of cases and epidemiology. These studies highlight the importance of epidemiological surveillance, the need for vaccination in this particular at risk population and the need for informative campaigns in order to prevent this disease

Introducción: en los últimos años, numerosos artículos relacionan el uso de los inhibidores de la bomba de protones (IBP) con posibles efectos adversos serios que han creado cierta alarma social. Objetivo: el objetivo de este trabajo es revisar la literatura de cara a elaborar un documento institucional de posicionamiento de la Sociedad Española de Patología Digestiva (SEPD) sobre la seguridad de los IBP a largo plazo. Material y métodos: se ha realizado una revisión exhaustiva de la literatura orientada a la presentación de conclusiones tras una valoración crítica sobre los siguientes temas: a) indicaciones actuales de los IBP; b) déficit de vitamina B12 y alteraciones neurológicas; c) déficit de magnesio; d) fracturas óseas; e) infecciones entéricas y neumonías; f) interacción con los derivados de las tienopiridinas; y e) complicaciones en pacientes cirróticos. Resultados: las indicaciones actuales de los IBP no han variado en los últimos años y están bien establecidas. No se recomienda la realización de un cribado generalizado de los niveles de vitamina B12 en todos los pacientes tratados de forma crónica con estos medicamentos; sin embargo, sí parece necesario controlar los niveles de magnesio al inicio del tratamiento y monitorizarlos en pacientes con toma de otros fármacos que puedan inducir hipomagnesemia. Existe mayor riesgo de fracturas óseas, aunque no se puede concluir que esta asociación sea causal. La asociación IBP e infección por Clostridium difficile es débil o moderada y el riesgo de neumonía es bajo. En pacientes con riesgo cardiovascular y tratados con derivados de las tienopiridinas -dada la ausencia de evidencias definitivas en relación a posibles interacciones medicamentosasparece que lo prudente sea sopesar adecuadamente los riesgos gastrointestinales y los riesgos cardiovasculares de cada paciente; cuando el riesgo gastrointestinal sea moderado/alto, debemos ejercer una acción terapéutica de prevención efectiva utilizando un IBP. En cirróticos descompensados deben ser indicados con cautela. Conclusiones: los IBP son fármacos seguros y los beneficios de su empleo, tanto a corto como a largo plazo superan los posibles efectos secundarios, siempre que la indicación, dosis y duración sean las adecuadas (AU)
Introduction: In the last few years a significant number of papers have related the use of proton-pump inhibitors (PPIs) to potential serious adverse effects that have resulted in social unrest. Objective: The goal of this paper was to provide a literature review for the development of an institutional position statement by Sociedad Española de Patología Digestiva (SEPD) regarding the safety of long-term PPI use. Material and methods: A comprehensive review of the literature was performed to draw conclusions based on a critical assessment of the following: a) current PPI indications; b) vitamin B12 deficiency and neurological disorders; c) magnesium deficiency; d) bone fractures; e) enteric infection and pneumonia; f) interactions with thienopyridine derivatives; e) complications in cirrhotic patients. Results: Current PPI indications have remained unchanged for years now, and are well established. A general screening of vitamin B12 levels is not recommended for all patients on a PPI; however, it does seem necessary that magnesium levels be measured at therapy onset, and then monitored in subjects on other drugs that may induce hypomagnesemia. A higher risk for bone fractures is present, even though causality cannot be concluded for this association. The association between PPIs and infection with Clostridium difficile is mild to moderate, and the risk for pneumonia is low. In patients with cardiovascular risk receiving thienopyridines derivatives it is prudent to adequately consider gastrointestinal and cardiovascular risks, given the absence of definitive evidence regardin potential drug-drug interactions; if gastrointestinal risk is found to be moderate or high, effective prevention should be in place with a PPI. PPIs should be cautiously indicated in patients with decompensated cirrhosis. Conclusions: PPIs are safe drugs whose benefits outweigh their potential side effects both short-term and long-term, provided their indication, dosage, and duration are appropriate (AU)

BACKGROUND: chronic liver disease (CLD) patients often present thrombocytopenia (TCP) and when severe, it may prevent them from undergoing necessary invasive procedures due to an increased bleeding risk. The lack of scientific evidence makes it impossible to determine key aspects of the current management and associated healthcare burden of these patients in Spain. PURPOSE: to gain insight into the current situation of patients with CLD-associated severe TCP undergoing invasive procedures in Spain, based on the experience of clinical experts. METHODS: national Delphi study involving 32 medical experts. RESULTS: the estimated prevalence of CLD-associated severe TCP is approximately 5,967, with an annual incidence of 1,148 new patients. Patients undergo a median of 1 (0-3) invasive procedures/year. Platelet transfusions (PTs) are the standard option to raise platelet counts and are associated with significant burden. The achievement of target platelet levels (≥ 50 X 109/l) after a transfusion is not routinely measured. The lack of effectiveness and short life span of transfused platelets can lead to procedure cancellations and bleeding events, which potentially affect patient outcomes. Adverse events occur in 1-25 % of patients, including mild (febrile and allergic reactions) and severe events (e.g., transfusion-related acute lung injury). Between 5-15 % of patients are unfit to receive PTs and approximately 3 % are treated off-label with thrombopoietin receptor agonists. CONCLUSIONS: this study provides a snapshot of the current situation in Spain, highlighting that the current management is poorly standardized and suboptimal in some cases. The results suggest the benefit of developing a consensus document to address some of these shortcomings and to advance in the search for alternatives to PTs
