Symptomatic gallstone disease: Recurrence patterns and risk factors for relapse after first admission, the RELAPSTONE study.

BACKGROUND: Delayed cholecystectomy in patients with symptomatic gallstone disease is associated with recurrence. Limited data on the recurrence patterns and the factors that determine them are available. OBJECTIVE: We aimed to determine the pattern of relapse in each symptomatic gallstone disease (acute pancreatitis, cholecystitis, cholangitis, symptomatic choledocholithiasis, and biliary colic) and determine the associated factors. METHODS: RELAPSTONE was an international multicenter retrospective cohort study. Patients (n = 3016) from 18 tertiary centers who suffered a first episode of symptomatic gallstone disease from 2018 to 2020 and had not undergone cholecystectomy during admission were included. The main outcome was relapse-free survival. Kaplan-Meier curves were used in the bivariate analysis. Multivariable Cox regression models were used to identify prognostic factors associated with relapses. RESULTS: Mean age was 76.6 [IQR: 59.7-84.1], and 51% were male. The median follow-up was 5.3 months [IQR 2.1-12.4]. Relapse-free survival was 0.79 (95% CI: 0.77-0.80) at 3 months, 0.71 (95% CI: 0.69-0.73) at 6 months, and 0.63 (95% CI: 0.61-0.65) at 12 months. In multivariable analysis, older age (HR = 0.57; 95% CI: 0.49-0.66), sphincterotomy (HR = 0.58, 95% CI: 0.49-0.68) and higher leukocyte count (HR = 0.79; 95% CI: 0.70-0.90) were independently associated with lower risk of relapse, whereas higher levels of alanine aminotransferase (HR = 1.22; 95% CI: 1.02-1.46) and multiple cholelithiasis (HR = 1.19, 95% CI: 1.05-1.34) were associated with higher relapse rates. CONCLUSION: The relapse rate is high and different in each symptomatic gallstone disease. Our independent predictors could be useful for prioritizing patients on the waiting list for cholecystectomies.

El tratamiento antiviral no mejora la ateromatosis subclínica en pacientes con hepatitis crónica por virus de la hepatitis C / Antiviral treatment does not improve subclinical atheromatosis in patients with chronic hepatitis caused by hepatitis C virus

Introducción: La infección crónica por el virus de la hepatitis C (VHC) es un factor de riesgo para desarrollar placas de ateroma, aunque se desconoce el posible efecto al eliminar el virus. Nuestro objetivo fue analizar si tras 12 meses de la erradicación del VHC por antivirales de acción directa (AAD) mejoraba la ateromatosis subclínica y existía modificación en la composición de las placas. Materiales y métodos: Estudio prospectivo que incluyó 85 pacientes con infección crónica por VHC en diferentes estadios de fibrosis, sometidos a AAD. Se excluyeron pacientes con antecedentes cardiovasculares, diabetes y enfermedad renal. Se realizó ecografía arterial (carótidas y femorales) para diagnosticar placa de ateroma (definida como grosor íntima-media≥1,5mm) y se analizó su composición (porcentaje de lípidos, fibrosis y calcio con software HEMODYN4) al inicio del estudio y tras 12 meses de finalizar la terapia. Resultados: Tras el seguimiento no se detectaron cambios en el grosor íntima-media (0,65mm vs. 0,63mm, p=0,240) ni en la presencia de placas (65,9%vs. 71,8%, p=0,063). Tampoco hubo modificación significativa en la composición de las mismas ni del territorio vascular afecto, observándose un aumento del perfil lipídico en sangre (p<0,001) tras 12 meses del tratamiento. Estos resultados se confirmaron en subgrupos por gravedad de enfermedad hepática. Discusión: La erradicación del VHC por AAD no mejora las placas de ateroma ni varía su composición, independientemente de la fibrosis hepática. Se precisan más estudios prospectivos que evalúen el riesgo residual cardiovascular tras la erradicación viral

Introduction: Chronic infection with hepatitis C virus is a risk factor for developing atheromatous plaques, although the possible effect of virus clearance is unknown. Our aim was to determine whether or not subclinical atheromatosis improved and there was any modification in the composition of the plaques 12 months after eradication of hepatitis C virus by direct-acting antiviral agents. Materials and methods: Prospective study that included 85 patients with chronic hepatitis C virus infection in different stages of fibrosis who were on direct-acting antiviral agents. Patients with a cardiovascular history, diabetes and kidney disease were excluded. An arterial ultrasound (carotid and femoral) was performed to diagnose atheromatous plaques (defined as intima-media thickness ≥1.5mm) and the composition (percentage of lipids, fibrosis and calcium with HEMODYN4 software) was analysed at the beginning of the study and 12 months after stopping the therapy. Results: After follow-up no changes were detected in the intima-media thickness (0.65mm vs. 0.63mm, P=.240) or in the presence of plaques (65.9% vs 71.8%, P=.063). There was also no significant change in their composition or affected vascular territory, with an increase in blood lipid profile (P<.001) after 12 months of treatment. These results were confirmed in subgroups by severity of liver disease. Discussion: The eradication of hepatitis C virus by direct-acting antiviral agents does not improve the atheroma plaques and nor does it vary their composition, regardless of liver fibrosis. More prospective studies are needed to evaluate residual cardiovascular risk after virus eradication

Predictive variables of sustained virological response after early discontinuation of triple therapy with telaprevir for genotype-1 HCV infection / Variables pronósticas de respuesta virológica sostenida tras la interrupción precoz del tratamiento triple con telaprevir de la infección por genotipo 1 del virus de la hepatitis C

BACKGROUND: Pivotal phase studies of telaprevir (TLV) and boceprevir (BOV) showed 10-56% rates of early treatment interruption. However, there have been no reports on the sustained virological response (SVR) rates of these patients. AIM: To assess the SVR rate in a large cohort of patients who discontinued triple therapy with TLV or BOV for reasons other than stopping rules and to identify variables predicting SVR. MATERIAL AND METHOD: A survey was sent to 15 hospitals in Catalonia asking them to report all TLV/BOV treatments finished by 31 May 2014. Demographic, clinical, laboratory, liver fibrosis and therapeutic data were recorded for treatments with early discontinuation. Logistic regression analysis, ROC curves and prognostic assessment of the variables identified were calculated. RESULTS: Twelve hospitals responded to the survey, representing 467 treatments and 121 (21.2%) early discontinuations, 76 (62.8%) due to stopping rules and 45 (37.2%) for other reasons. Early discontinuation was more frequent with BOV [38.2% (50/131) versus 21.1% (71/336) p < 0.005], mainly due to stopping rules [78% (39/50) versus 52.1% (37/71); p = 0.004]. SVR was achieved in 21/121 patients (17.4%), 19/71 (26.8%) treated with TLV and 2/50 (4.0%) treated with BOV. In patients discontinuing treatment for reasons other than stopping rules, SVR was achieved in 19/37 (55.9%) treated with TLV and in 2/11 (18.2%) treated with BOV. The SVR rate in patients treated with TLV who discontinued due to a severe adverse event was 61.5% (16/26). A logistic regression analysis was performed only with triple therapy with TLV and early discontinuation. The predictive variables of SVR were undetectable HCV-RNA at treatment week 4 and treatment length longer than 11 weeks. Treatment duration longer than 11 weeks showed the best accuracy (0.794), with a positive predictive value of 0.928. CONCLUSIONS: Early discontinuation of TLV-based triple therapy due to reasons other than stopping rules still have a significant SVR rate (55.9%). Undetectable HVC-RNA at week 4 of treatment and treatment duration longer than 11 weeks are predictive of SVR in this subset of patients

ANTECEDENTES: Los estudios de registro de telaprevir (TLV) y boceprevir (BOV) han mostrado tasas de interrupción precoz del tratamiento del 10-56%, pero no se ha comunicado la respuesta virológica sostenida (RVS) de estos pacientes. OBJETIVOS: Analizar la RVS, y los factores predictivos de esta, en una cohorte extensa de pacientes que pararon precozmente el tratamiento triple con TLV/BOV por causas diferentes a reglas de parada. MATERIAL Y MÉTODO: Se envió a 15 de hospitales de Cataluña un cuestionario relativo a los tratamientos con TLV/BOV finalizados antes del 31 de mayo de 2014, incluyendo información clínica, analítica, elastométrica y terapéutica de aquellos interrumpidos precozmente. Se realizaron análisis de regresión logística, curvas ROC y estimaciones pronósticas de las variables identificadas. RESULTADOS: Contestaron la encuesta 12 hospitales, sumando un total de 467 tratamientos con 121 (21,2%) interrupciones precoces del mismo, 76 (62,8%) por reglas de parada y 45 (37,2%) por otras causas. Hubo más paradas precoces en los tratamientos con BOV (38,2% [50/131] versus 21,1% [71/336]; p < 0,005), principalmente debidas a reglas de parada (78% [39/50] versus 52,1% [37/71]; p = 0,004). Alcanzaron RVS 21/121 pacientes (17,4%), 19/71 (26,8%) tratados con TLV y 2/50 (4,0%) tratados con BOV. En los pacientes que pararon el tratamiento por causas distintas a reglas de parada se alcanzó la RVS en 19/37 (55,9%) tratados con TLV y en 2/11 (18,2%) tratados con BOV. Los pacientes tratados con TLV que pararon el tratamiento por efecto adverso grave tuvieron una tasa de RVS del 61,5% (16/26). El análisis de regresión logística se hizo solo con los tratamientos triples con TLV parados precozmente. Las variables predictivas de RVS fueron el ARN-VHC indetectable en semana 4 y la duración del tratamiento mayor de 11 semanas. El mejor valor pronóstico (0,794) lo tuvo la duración total del tratamiento mayor de 11 semanas, con un VPP de 0,928. CONCLUSIONES: Los pacientes que paran precozmente el tratamiento triple con TLV por causas diferentes a reglas de parada conservan una tasa de RVS relevante (55,9%) en esta cohorte. El ARN-VHC indetectable en semana 4 y la duración del tratamiento mayor de 11 semanas son predictivas de RVS de este subgrupo de pacientes
