Background The acute and long-term effects of severe acute respiratory syndrome coronavirus 2 infection in individuals with GN are still unclear. To address this relevant issue, we created the International Registry of COVID-19 infection in GN.Methods We collected serial information on kidney-related and -unrelated outcomes from 125 GN patients (63 hospitalized and 62 outpatients) and 83 non-GN hospitalized patients with coronavirus disease 2019 (COVID-19) and a median follow-up period of 6.4 (interquartile range 2.3–9.6) months after diagnosis. We used logistic regression for the analyses of clinical outcomes and linear mixed models for the longitudinal analyses of eGFR. All multiple regression models were adjusted for age, sex, ethnicity, and renin-angiotensin-aldosterone system inhibitor use.Results After adjustment for pre-COVID-19 eGFR and other confounders, mortality and AKI did not differ between GN patients and controls (adjusted odds ratio for AKI=1.28; 95% confidence interval [CI], 0.46 to 3.60; P=0.64). The main predictor of AKI was pre-COVID-19 eGFR (adjusted odds ratio per 1 SD unit decrease in eGFR=3.04; 95% CI, 1.76 to 5.28; PConclusions Pre-COVID-19 eGFR is the main risk factor for AKI regardless of GN diagnosis. However, GN patients are at higher risk of impaired eGFR recovery after COVID-19-associated AKI. These patients (especially those with high baseline proteinuria or a diagnosis of focal segmental glomerulosclerosis or minimal change disease) should be closely monitored not only during the acute phases of COVID-19 but also after its resolution.

Summary Background Patients on regular dialysis show a poor response to hepatitis B vaccine due to uremia. A recombinant HB vaccine (containing an improved adjuvant system AS04, HBV-AS04) has been licensed but the evidence on its efficacy and safety in dialysis population over the long term is extremely limited. Aim We have measured antibody (anti-HBs) persistence for up to 72 months in a large cohort of patients on long-term dialysis (with susceptibility to HBV infection) who underwent vaccination with HBV-AS04 vaccine. Methods Patients were prospectively recruited to receive four 20-mcg doses of HBV-AS04 by intramuscular route (deltoid muscle). Two vaccine schedules were adopted: 0,1,2, and 3 month (n = 217 patients) and 0,1,2, and 6 month (n = 31 patients). Anti-HBs antibody concentrations were tested at 1,2,3, 4, 7 and 12 months and then every year up to 72 months. Multivariate analysis was made to find the baseline parameters that were associated with the immune response to HBV-AS04 vaccine. Results Two hundred and seventy-two patients were included and 248 completed the study. At completion of vaccine schedule, the frequency of responders (anti-HBs titers ≥ 10 mIU/mL) was 81.5% (202/248) (mean anti-HBs antibody titers, 384.9 ± 391.9 mIU/mL), according to per-protocol analysis. On the grounds of univariate analysis, age was lower in responder than non- responder patients to HBV AS04 even if no statistical significance was achieved (P = 0.09). The sero-protection rate at month 72 was 77% (7/9) (anti-HBs antibody titers, 184.9 ± 360.1 mIU/mL, P = 0.001). Multivariate analysis found a relationship between sero-response rate and age (P = 0.04). No major side effects and no de novo HBV episodes were observed. Conclusions Our open-label nonrandomized trial performed in a ‘real-world’ practice showed the persistence of anti-HBs antibody among responder patients over a very long follow-up. Studies with longer observation periods are under way.

BACKGROUND AND AIMS:The advent of direct-acting antiviral agents promises to change the management of hepatitis C virus infection (HCV) in patients with chronic kidney disease (CKD), a patient group in which the treatment of hepatitis C was historically challenging. We investigated the safety and efficacy of all-oral, interferon-free direct-acting antiviral agents for the treatment of hepatitis C in a 'real-world' cohort of patients with CKD.METHODS:We performed an observational single-arm multi-centre study in a large (n=198) cohort of patients with stage 1-3 CKD who underwent antiviral therapy with DAAs for the treatment of HCV. The primary end-point was sustained virologic response (serum HCV RNA

Resumen: Introducción: A pesar de la frecuencia con que la anemia está presente en los pacientes con enfermedad renal crónica (ERC), su relación con lesiones gastrointestinales no ha sido estudiada. Método: Estudio observacional analítico transversal de un año de reclutamiento para determinar la prevalencia de lesiones gastrointestinales endoscópicas y los factores de riesgo asociados en pacientes asintomáticos con ERC estadios 1-5 y anemia que presentaban un test inmunoquímico cualitativo de sangre oculta en heces positivo. Resultados: Se analizaron 9.658 pacientes con ERC, de los que 286 (2,9%) presentaban anemia; 198 tuvieron un test de sangre oculta en heces positivo (47% varones, 71,1 ± 11,8 años). El estudio endoscópico reveló 255 lesiones, con al menos una lesión en el 68,2%, siendo las más prevalentes: pólipos colorrectales adenomatosos (39,6%), lesiones agudas de la mucosa gástrica (22,6%), lesiones neoplásicas (15,1%), angiodisplasias (14,4%), esofagitis (8,4%), enfermedad inflamatoria intestinal (4,8%) y colitis isquémica (3,1%). La uremia y el ácido acetilsalicílico fueron identificados como factores de riesgo de lesiones agudas de la mucosa gástrica. Las angiodisplasias se relacionaron con el enolismo, el mayor estadio de ERC, la anemia y la ausencia de respuesta a agentes estimulantes de la eritropoyesis. La edad y la anemia refractaria constituyeron factores de riesgo de pólipos adenomatosos y cáncer colorrectal. Conclusión: Los pacientes renales con anemia podrían beneficiarse de un estudio endoscópico debido a la alta prevalencia de lesiones gastrointestinales que presentan, particularmente pólipos adenomatosos y cáncer colorrectal, más frecuentes en los mayores de 50 años con ERC estadios 3-5. Abstract: Introduction: Despite the frequency with which anaemia is present in patients with chronic kidney disease (CKD), its relationship with gastrointestinal lesions has not been studied. Method: A cross-sectional, analytical, observational study involving one year of recruitment was carried out to determine the prevalence of endoscopic gastrointestinal lesions and associated risk factors in asymptomatic patients with chronic kidney disease stages 1-5 and anaemia who had a positive qualitative immunochemical faecal occult blood test. Results: A total of 9,658 patients with CKD were analysed, of which 286 (2.9%) had anaemia; 198 had a positive faecal occult blood test (47% male, 71.1 ± 11.8 years). The endoscopic study revealed 255 lesions, with at least one lesion in 68.2% of patients, with the most prevalent being: adenomatous colorectal polyps (39.6%), acute lesions of the gastric mucosa (22.6%), neoplastic lesions 15.1%), angiodysplasia (14.4%), oesophagitis (8.4%), inflammatory bowel disease (4.8%) and ischaemic colitis (3.1%). Uraemia and acetylsalicylic acid were identified as risk factors for acute gastric mucosal lesions. Angiodysplasia was associated with alcoholism, a more advanced stage of chronic kidney disease, anaemia, and lack of response to erythropoiesis-stimulating agents. Age and refractory anaemia were risk factors for adenomatous polyps and colorectal cancer. Conclusion: Renal patients with anaemia could benefit from an endoscopic study due to their high prevalence of gastrointestinal lesions, particularly adenomatous polyps and colorectal cancer, which are more common in those over 50 years of age with CKD stages 3-5.

Hepatitis C virus (HCV) infection is one of the main causes of liver cirrhosis worldwide. The long-term impact of HCV infection is highly variable, ranging from minimal histological changes to extensive fibrosis with hepatocellular carcinoma. The development of HCV drugs has increased dramatically in recent years, even in special populations such as chronic kidney disease patients. Classical treatment of chronic hepatitis C was based on the administration of interferon and ribavirin for 24-48 weeks, which was associated with a poor viral response and a high rate of side effects, especially in patients with a lower estimated glomerular filtration rate. The current high availability of the new direct-acting antivirals renders the classification of these agents for this special population necessary. The Spanish Association of the Liver and the Kidney has produced a position statement on the treatment of HCV infection in chronic kidney disease patients since the evidence to guide this treatment is scant and what evidence does exist is weak. The recommendations are based on the results of clinical trials and controlled studies conducted to date, with data published hitherto by the authors of these studies. Since the indications for treatment have been evaluated by other societies or are dependent on internal clinical protocols, the main goal of this position statement is to assist in decision-making when choosing a therapeutic option.

Background and Aims: The advent of direct-acting antiviral agents promises to change the management of hepatitis C in patients with end-stage renal disease, a patient group where the treatment of hepatitis C was historically challenging. We investigated the safety and efficacy of all-oral, interferon-free direct-acting antiviral agents for the treatment of hepatitis C in a ‘real-world’ group of patients with end-stage renal disease. Methods: We performed a single-arm, multi-centre study in a cohort (n=30) of patients with advanced chronic kidney disease (mostly on dialysis) who underwent antiviral therapy with direct-acting antiviral agents. The primary end-point was sustained virologic response (serum hepatitis C virus RNA < 15 mIU/mL, 12 weeks after treatment ended). We collected data on on-treatment adverse events, serious adverse events and laboratory abnormalities. Results: In total, 23 (77%) and 7 (23%) patients underwent regular dialysis and had chronic kidney disease at pre-dialysis stage, respectively. Six regimens were adopted: elbasvir/grazoprevir ( n = 6), ledipasvir/sofosbuvir ± ribavirin ( n = 4), PrOD regimens ± ribavirin ( n = 10), simeprevir + daclatasvir ( n = 3), sofosbuvir + daclatasvir ± ribavirin ( n = 3), sofosbuvir + ribavirin ( n = 4). The SVR12 rate was 90% (95% confidence interval, 74%; 96%). A total of 27 (90%) patients achieved SVR12; there were three virologic failures – two were non-responders and one had a viral breakthrough while on therapy. Adverse events occurred in 53% (16/30) (95% confidence interval, 0.39; 0.73) of patients and were managed clinically without discontinuation of therapy or hospitalization. The most common adverse event was anaemia ( n = 12) that required blood transfusions in seven individuals; deterioration of kidney function occurred in one (14%). Conclusion: All-oral, interferon-free therapy with direct-acting antiviral agents for chronic hepatitis C virus in advanced chronic kidney disease was effective and well tolerated in a ‘real-life’ clinical setting. Careful monitoring of haemoglobin and serum creatinine during therapy with direct-acting antiviral agents is suggested. Studies are under way to address whether sustained viral response translates into better survival in this population.

Despite the frequency with which anaemia is present in patients with chronic kidney disease (CKD), its relationship with gastrointestinal lesions has not been studied.A cross-sectional, analytical, observational study involving one year of recruitment was carried out to determine the prevalence of endoscopic gastrointestinal lesions and associated risk factors in asymptomatic patients with chronic kidney disease stages 1-5 and anaemia who had a positive qualitative immunochemical faecal occult blood test.A total of 9,658 patients with CKD were analysed, of which 286 (2.9%) had anaemia; 198 had a positive faecal occult blood test (47% male, 71.1±11.8 years). The endoscopic study revealed 255 lesions, with at least one lesion in 68.2% of patients, with the most prevalent being: adenomatous colorectal polyps (39.6%), acute lesions of the gastric mucosa (22.6%), neoplastic lesions 15.1%), angiodysplasia (14.4%), oesophagitis (8.4%), inflammatory bowel disease (4.8%) and ischaemic colitis (3.1%). Uraemia and acetylsalicylic acid were identified as risk factors for acute gastric mucosal lesions. Angiodysplasia was associated with alcoholism, a more advanced stage of chronic kidney disease, anaemia, and lack of response to erythropoiesis-stimulating agents. Age and refractory anaemia were risk factors for adenomatous polyps and colorectal cancer.Renal patients with anaemia could benefit from an endoscopic study due to their high prevalence of gastrointestinal lesions, particularly adenomatous polyps and colorectal cancer, which are more common in those over 50 years of age with CKD stages 3-5.

Previous studies have examined control rates of office blood pressure (BP) in chronic kidney disease (CKD). However, recent evidence suggests major discrepancies between office and 24-hour BP values in hypertensive populations. This study examined concordance/discordance between office- and ambulatory-based BP control in a large cohort of patients with CKD.Cross-sectional.5,693 hypertensive individuals with CKD stages 1-5 from the Spanish ABPM (ambulatory BP monitoring) Registry.Thresholds of 140/90 and 130/80 mm Hg for office BP and 24-hour ambulatory BP, respectively. Age, sex, body mass index, waist circumference, hypertension duration, kidney measures, diabetes, dyslipidemia, target-organ damage, and cardiovascular comorbid conditions.Misclassification of BP control as "white-coat" hypertension (office BP ≥140/90 mm Hg, 24-hour BP130/80 mm Hg) or masked hypertension (office BP140/90 mm Hg, 24-hour BP ≥130/80 mm Hg).Standardized office-based BP and 24-hour ABPM.Mean age was 61.0 ± 13.9 (SD) years and 52.6% were men. The proportion with white-coat hypertension was 28.8% (36.8% of patients with office BP ≥140/90 mm Hg) and that of masked hypertension was 7.0% (but 32.1% of patients with office BP140/90 mm Hg). Female sex, aging, obesity, and target-organ damage were associated with white-coat hypertension; aging and obesity were associated with masked hypertension. Only 21.7% and 8.1% of the CKD population had office BP140/90 and130/80 mm Hg, respectively. In contrast, 43.5% of individuals had average 24-hour BP130/80 mm Hg.Cross-sectional design, longitudinal associations cannot be established.Misclassification of BP control at the office was observed in 1 of 3 hypertensive patients with CKD. Ambulatory-based control rates were far better than office-based rates. Nevertheless, the burden of uncontrolled ambulatory BP and misclassification of BP control at the office constitutes a call for wider use of ABPM to evaluate the success of hypertension treatment in patients with CKD.

Resumen Introduccion La infeccion cronica por el virus de la hepatitis C (VHC) se ha asociado a enfermedad glomerular, que se manifiesta mediante proteinuria con o sin disfuncion renal. Metodo Estudio observacional analitico transversal con 120 pacientes infectados por el VHC y 145 controles VHC-negativos para determinar la prevalencia de dano renal asociada al VHC y su relacion con factores de riesgo. Se recogieron datos de la historia clinica y anamnesis y se realizaron al menos 3 analisis de sangre y orina en un ano. La insuficiencia renal se definio por un filtrado glomerular estimado inferior a 60 ml/min/1,73 m 2 y/o una microalbuminuria superior a 20 mg/l o un indice microalbuminuria/creatinina mayor de 30 μg/mg. Resultados La prevalencia de microalbuminuria e insuficiencia renal se estimo en el 19,3 y 11,7% en los VHC-positivos vs el 10,5 y 0,7% en los VHC-negativos (p = 0,04), respectivamente. El 26,1% de los pacientes VHC-positivos tenia algun signos de dano renal vs el 11,8% de los VHC-negativos (p = 0,003). La infeccion por el VHC se asocio de forma independiente y significativa con la probabilidad de deterioro de la funcion renal. La prevalencia de microalbuminuria e insuficiencia renal se incremento progresivamente con el aumento de edad. Conclusion Los pacientes VHC-positivos presentan una alta prevalencia de microalbuminuria e insuficiencia renal en comparacion con sujetos VHC-negativos. El riesgo de insuficiencia renal asociado al VHC es independiente en presencia de otros factores predisponentes como hipertension arterial y diabetes.

Amplification of hepatitis C virus (HCV) RNA from blood detected occult HCV infections in 30.9% of 210 HCV-seronegative dialysis patients with abnormal liver enzyme levels that had evaded standard HCV testing practices. Isolated HCV core-specific antibody detection identified three additional anti-HCV screening-negative patients lacking HCV RNA amplification in blood who were considered potentially infectious. Together, these findings may affect management of the dialysis setting.

OBJECTIVES The aims of this study were to determine the prevalence of exocrine pancreatic insufficiency (EPI) and chronic pancreatitis (CP) in patients with chronic alcoholic liver disease and to analyze the possible associated factors. METHODS This is an analytical observational study of cases and controls for a sample of patients with chronic alcoholic and nonalcoholic liver disease. Exocrine pancreatic insufficiency was diagnosed using the C mixed-triglyceride breath test. Patients with abdominal pain underwent endoscopic ultrasonography for CP evaluation using the Wiersema criteria. RESULTS A total of 154 patients were included, 129 with alcoholic liver disease (83 with cirrhosis) and 25 with nonalcoholic liver disease. Exocrine pancreatic insufficiency was found in 55.2% versus 16.7% (P < 0.001), 70% of patients without cirrhosis compared with 46.2% of patients with cirrhosis had pancreatic insufficiency (P = 0.017), and 82.7% of patients with alcoholic liver disease and abdominal pain had CP (P < 0.001). Exocrine pancreatic insufficiency was associated with the male sex, alcohol intake, abdominal pain, degree of liver failure, and the absence of portal hypertension. Chronic pancreatitis was correlated with age younger than 55 years and abdominal pain. CONCLUSIONS Patients with alcoholic liver disease had a high prevalence of EPI and CP; this prevalence was even higher in patients who have not yet developed cirrhosis with liver failure or portal hypertension.

Fundamento Estudiar la sensibilidad a antifungicos de las levaduras patogenas emergentes para conocer su posible resistencia ante la necesidad de aplicar un tratamiento Material y metodos Se investiga la sensibilidad in vitro de 69 cepas de levaduras aisladas de muestras clinicas, pertenecientes a 24 especies diferentes, frente a anfotericina B, fluconazol, itraconazol, ketoconazol y 5-fluorocitosina, utilizando el metodo Sensititre YeastOne.® Resultados Solamente 9 especies se mostraron sensibles a todos los antifungicos: Candida famata, C. guillermondii, C. holmii, C. kefyr, C. pelliculosa, C. rugosa, C. utilis, C. zeylanoides y Trichosporon cutaneum; las demas presentaron resistencia a algun antifungico. C. haemulonii, Pichia farinosa y Trichosporon mucoides, fueron resistentes a anfotericina B; C. haemulonii, C. inconspicua, C. lusitaniae, C. norvegensis, C. pintolepesii, C. valida, P. ohmeri, Rhodotorula glutinis, R. minuta, R. mucilaginosa y Saccharomyces cerevisiae fueron resistentes a derivados azolicos; Blastoschizomyces capitatus y C. lipolytica fueron resistentes a 5-fluorocitosina Conclusiones La resistencia de las levaduras patogenas emergentes a anfotericina B y 5-fluorocitosina es escasa, mientras que para los azoles es bastante significativa, especialmente al fluconazol (36%). Muchas de estas levaduras plantean problemas de resistencia intrinseca. En las infecciones por levaduras, es importante la correcta identificacion de las especies y el estudio de sensibilidad in vitro para elegir el tratamiento antifungico mas adecuado

Visceral artery aneurysms are rare vascular lesions. Hepatic aneurysms are the second most common type of visceral aneurysm after those of the splenic artery. These aneurysms often have a nonspecific clinical presentation and are difficult to diagnose before rupture. Because the natural course of hepatic aneurysms leads to rupture, with a high rate of morbidity and mortality, their early diagnosis is essential for surgical correction. We report a case of obstructive jaundice caused by a 7-cm gastroduodenal artery aneurysm in which the diagnosis was suggested by abdominal computed tomography and magnetic resonance cholangiography and was confirmed by angiography. The patient was surgically treated. In the following 48 h he presented ischemic-based acute hepatic failure and underwent left hepatic lobe resection. The patient finally died from a pulmonary thromboembolism.

The SHECTS study, approved by the Spanish Society of Nephrology, has the goal of analysing the level of examination and follow-up of patients with chronic hepatitis C virus (HCV) infections on haemodialysis, and to determine the current prevalence of these patients.A national, multi-centre, cohort study carried out between September 2010 and September 2011. We sent a data collection folder to all Spanish haemodialysis units to include information regarding each centre and the nephrological/hepatological situation of their HCV-positive patients.A total of 187 haemodialysis units (71 hospital-based) participated in the study. The global prevalence of HCV was estimated at 5.6%. The most common cause of chronic kidney disease was glomerular (25%); of the 72.1% of patients who had undergone a renal biopsy, 23.2% had glomerulonephritis that could have been associated with HCV. Genotyping had not been carried out in 64%, liver ultrasound had not been applied in 61.3%, and liver biopsies were not performed in 87.7%. One-third of all patients received care from a gastroenterologist. Antiviral treatment was administered to 26.6% of patients, with a sustained viral response in 35.3% and suspension of treatment in 67.4%.The prevalence of HCV in patients on haemodialysis in Spain has decreased to the point of reaching similar rates to those of neighbouring countries. These patients receive incomplete analyses of liver condition, and individuals who receive antiviral treatment and untreated patients constitute a large proportion, despite having low viral loads and being candidates for kidney transplants.

Rheumatological diseases and, firstly, rheumatoid arthritis (RA) remain a major cause of secondary amyloidosis. The emergence of biological agents such as adalimumab in the early treatment of RA can be an effective alternative to stop the development and progression of secondary amyloidosis. Not all patients will respond the same way to treatment; we must consider associated comorbidity, the poor prognosis factors for predicting therapeutic response and possible adverse effects. In the adverse effects of biological therapies, there has been an increase in the rate of lethal infections and congestive heart failure. We present two cases with renal amyloidosis secondary to RA who had a different clinical course: our 1st case had a good response to Adalimumab while the 2nd case evolved unfavourably after treatment, and died from cardiovascular complications.

Chronic hepatitis C virus (HCV) infection is associated with glomerular disease, which is manifested by proteinuria with or without renal dysfunction.To determine the prevalence of HCV-associated renal injury and associated risk factors, we performed an observational, analytic, cross-sectional study of 120 HCV-positive patients and 145 HCV-negative controls. Data were gathered from medical records and history-taking and at least three blood and urine analyses were performed over a 1-year period. Renal insufficiency was defined as an estimated glomerular filtration rate of less than 60ml/min/1.73 m2 and/or microalbuminuria of more than 20mg/l or a microalbumin/creatinine ratio higher than 30 mcg/mg.The prevalence of microalbuminuria and renal insufficiency was 19.3% and 11.7% in HCV-positive patients versus 10.5% and 0.7% in HCV-negative controls (p 0.04), respectively. A total of 26.1% of HCV-positive patients had signs of renal injury compared with 11.8% of HCV-negative controls (p 0.003). HCV infection was independently and significantly associated with the probability of worsening of renal function. The prevalence of microalbuminuria and renal insufficiency progressively increased with greater age.HCV-positive patients show a high prevalence of microalbuminuria and renal insufficiency compared with HCV-negative individuals. The risk of HCV-associated renal insufficiency is independent of the presence of other predisposing factors such hypertension and diabetes.

We report a case of fungemia caused by Kodamaea (Pichia) ohmeri associated with surgery in a patient with a history of diabetes and chronic renal failure. Kodamaea ohmeri is a yeast rarely involved in human infections. Since the first report of a case of fungemia in 1998, only thirteen cases of K. ohmeri infection have been so far described in the medical literature.

Isolation of Hanseniaspora uvarum, a yeast of the ascomycetes group, whose anamorph corresponds to Kloeckera apiculata, obtained from stool and two ungual specimens from three patients, is reported. This yeast has been found in soil, water, various fruits, bivalve molluscs, crabs, prawns and fruit flies; in Spain, it has been described in the fermentation processes of some wines. In our region, it has also been found in the intestine of mackerel ( Scomber scombrus). Its finding in humans constitutes a clinical rarity.

We report a case of fungemia caused by Kodamaea (Pichia) ohmeri associated with surgery in a patient with a history of diabetes and chronic renal failure. Kodamaea ohmeri is a yeast rarely involved in human infections. Since the first report of a case of fungemia in 1998, only thirteen cases of K. ohmeri infection have been so far described in the medical literature.

ResumenIntroducciónEl estudio PIBHE, promovido por la Asociación Española de Hígado y Riñón y el Grupo de Virus en Diálisis de la Sociedad Española de Nefrología, es el primer estudio que determina la situación de los pacientes en hemodiálisis con infección crónica por el VHB y la inmunización frente a la vacuna.MétodoEstudio nacional multicéntrico, observacional, de corte transversal, entre enero de 2013 y de 2014. Se envió un cuaderno de recogida de datos a todos los servicios de nefrología y unidades extrahospitalarias de hemodiálisis de España, para que lo cumplimentaran a partir de la historia clínica del paciente, tras consentimiento informado. Los datos se incluyeron en una base central.ResultadosParticiparon 215 centros (15.645 pacientes), con una prevalencia del VHB del 1,03%. El 7,2% de los pacientes VHB(+) estaba coinfectado por el VHC o VIH. La carga viral era inferior a 2.000 UI/ml en el 80%. Los niveles de GOT y GPT fueron de 19,1±10,1 y 15,9±9,6 UI/ml, respectivamente. La biopsia hepática se había realizado en el 7,1%. El 30% había recibido tratamiento antiviral, que se había suspendido en el 12,5%. El más empleado había sido entecavir (13,3%), seguido de lamivudina (10%), adefovir y tenofovir (6,7%) e interferón (3,3%). El 34,5% era candidato a trasplante renal y el 6,9% no había sido evaluado. Se encontraban en seguimiento por un digestólogo el 64,3%. No había sido vacunado el 27,2% de los pacientes VHB(−) sin inmunización. Se emplearon 14 pautas distintas de vacunación, con un 58,8% de inmunización. La media de anti-HBs se situaba en 165,7±297,8mUI/ml. El 72,7% de los pacientes había recibido un ciclo de vacunación; el 26,4%, 2 ciclos; el 1,0%, 3 ciclos y el 11,6%, una dosis de recuerdo. El 28,3% tuvo una respuesta pobre (anti-HBs 10-99mUI/ml); el 22,4%, una respuesta óptima (anti-HBs 100-999mUI/ml); y el 7,9%, una respuesta excelente (anti-HBs≥1.000mUI/ml). La edad se asoció significativamente con la respuesta a la vacunación, de manera que los pacientes que no respondieron tenían una edad media significativamente mayor que los pacientes que obtuvieron cualquier tipo de respuesta (p
