Relación entre la hepatitis crónica vírica B y/o C y el liquen plano bucal

Introducción: La hepatopatía crónica es una patología producida, principalmente, por la ingesta alcohólica y por la infección de los virus de la hepatitis B y/o C. En los últimos años se ha discutido ampliamente la posible asociación entre la hepatopatía crónica y el liquen plano bucal. Recientemente, se ha especulado que la asociación entre liquen plano bucal y la enfermedad hepática tiene una base de origen vírica. Material y método: El objetivo de este estudio transversal emparejado es conocer si existe relación entre las hepatitis víricas B y/o C crónicas y el liquen plano bucal. Para ello, se seleccionaron dos grupos de 100 individuos cada uno: un grupo de casos, formado por pacientes infectados con el virus de la hepatitis B y/o C y un grupo control, equiparado en edad y sexo al grupo de casos, cuyos pacientes no padecían hepatopatía alguna. Se exploró la cavidad bucal, principalmente para detectar lesiones de liquen plano en ambos grupos, aunque se registró cualquier otra alteración de la mucosa bucal. Resultados: No se encontró ningún paciente del grupo de casos con liquen plano bucal, siendo cuatro los individuos que padecían esta patología en el grupo control. Conclusiones: En nuestro estudio no se halló ninguna asociación entre la infección por el virus de la hepatitis B y/o C y el liquen plano bucal.Introduction: The chronic liver disease is a pathology produced, mainly, by the alcohol chronic abuse and by the hepatitis B and/or C virus infection. In the last years, it has been widely discussed the possible association between chronic liver disease and oral lichen planus. Recently, it has been suggested that the association between oral lichen planus and liver disease has a viral origin. Material and method: The objective of this transversal matched study is to know if there is a relationship between B and/or C viral chronic hepatitis and oral lichen planus. Two groups of 100 patients were selected: a case group with patients infected with hepatitis B and/or C virus, and a control group without liver disease matched in age and gender. Oral cavity was explored to detect lichen planus in both groups, but we registered other mucosal alterations. Results: We did not found any patient of the case group with oral lichen planus, but four patients with this disease in the control group. Conclusions: In our study we did not found any association between the infection with the hepatitis B and/or C virus and oral lichen planus

Estudio del estado bucodental del paciente trasplantado hepático

Desde que se realizó en España el primer trasplante hepático en el año 1984 los avances en la técnica quirúrgica y en los fármacos inmunosupresores empleados han producido un aumento en el número de pacientes trasplantados. El objetivo del presente estudio fue valorar el estado bucodental de los pacientes trasplantados hepáticos. Se realizó un estudio descriptivo transversal de una muestra de pacientes que habían sido sometidos a un trasplante hepático en el Hospital Príncipes de España de la Ciudad Sanitaria y Universitaria de Bellvitge (L Hospitalet de Llobregat - Barcelona). Los datos recogidos fueron los de filiación, los de la historia médica general, los de la historia bucodental y los de la exploración intrabucal. En total fueron examinados 53 individuos, 28 hombres y 25 mujeres, con una edad media de 57,6 años. El tiempo medio del trasplante fue de 3 años y 9 meses. La causa más frecuente del trasplante hepático fue la cirrosis hepática por el virus de la hepatitis C (49,1%). Los inmunosupresores más utilizados fueron la ciclosporina y el tacrolimus. El índice CAOD de la muestra fue de 11,2. En cuanto a la patología periodontal, el 22% de los pacientes dentados presentaban agrandamiento gingival, la mitad de los dentados tenían recesiones gingivales y el 34% presentaban algún tipo de movilidad dentaria. A la exploración de la mucosa bucal, la patología más prevalente fue la lengua fisurada (39,6%), la lengua saburral (28,3%) y la xerostomía (18,9%). La patología bucodental de estos pacientes está relacionada con el uso de fármacos inmunosupresores y de otros factores tales como la falta de medidas preventivas. Los datos de este estudio demuestran que sería necesario instaurar tratamientos preventivos en este grupo de población.Since the first liver transplantation in Spain was carried out in 1984, advances in surgical technique and immunosuppressive drugs have facilitated an increase in the number of transplants performed. The present study evaluates buccodental health in liver transplant patients. A cross-sectional descriptive study was made of a sample of patients subjected to liver transplantation in Príncipes de España Hospital (Bellvitge University Health Care Complex, L Hospitalet de Llobregat, Barcelona - Spain). Information was collected relating to demographic characteristics, general clinical history, buccodental history and intraoral exploratory findings. A total of 53 individuals were evaluated (28 males and 25 females, with a mean age of 57.6 years). The mean time elapsed from transplantation was 3 years and 9 months. The most frequent indication for liver transplantation was liver cirrhosis due to hepatitis C virus (HCV) infection (49.1% of the global series). The most widely used immunosuppressors were cyclosporine and tacrolimus. The CAOD index of the series was 11.2. In relation to periodontal disease, 22% of the dentate patients showed gingival overgrowth, while half of those with teeth had gingival recessions, and 34% presented some type of dental mobility. The examination of the oral mucosa showed fissured tongue to be the most common disorder (39.6%), followed by saburral tongue (28.3%) and xerostomia (18.9%). Buccodental pathology in these patients is related to the use of immunosuppressor medication and other factors such as a lack of preventive measures. The findings of the present study point to the need for preventive treatments in this population group

Effectiveness, safety/tolerability of OBV/PTV/r ± DSV in patients with HCV genotype 1 or 4 with/without HIV-1 co-infection, chronic kidney disease (CKD) stage IIIb-V and dialysis in Spanish clinical practice - Vie-KinD study

Limited data are available on the effectiveness and tolerability of direct-acting antivirals (DAAs) therapies in the real world for HCV-infected patients with comorbidities. This study aimed to describe the effectiveness of OBV/PTV/r ± DSV (3D/2D regimen) with or without ribavirin (RBV) in HCV or HCV/HIV co-infected patients with GT1/GT4 and CKD (IIIb-V stages), including those under hemodialysis and peritoneal dialysis in routine clinical practice in Spain in 2015.Non-interventional, retrospective, multicenter data collection study in 31 Spanish sites. Socio-demographic, clinical variables, study treatment characteristics, effectiveness and tolerability data were collected from medical records.Data from 135 patients with a mean age (SD) of 58.3 (11.4) years were analyzed: 92.6% GT1 (81.6% GT1b and 17.6% GT1a) and 7.4% GT4, 14 (10.4%) HIV/HCV co-infected, 19.0% with fibrosis F3 and 28.1% F4 by FibroScan®, 52.6% were previously treated with pegIFN and RBV. 11.1%, 14.8% and 74.1% of patients had CKD stage IIIb, IV and V respectively. 68.9% of patients were on hemodialysis; 8.9% on peritoneal dialysis and 38.5% had history of renal transplant. A total of 125 (96.2%) of 135 patients were treated with 3D, 10 (7.4%) with 2D and 30.4% received RBV. The overall intention-to-treat (ITT) sustained virologic response at week 12 (SVR12) was 92.6% (125/135) and the overall modified-ITT (mITT) SVR12 was 99.2% (125/126). The SVR12 rates (ITT) per sub-groups were: HCV mono-infected (91.7%), HCV/HIV co-infected (100%), GT1 (92.0%), GT4 (100%), CKD stage IIIb (86.7%), stage IV (95%) and stage V (93%). Among the 10 non-SVR there was only 1 virologic failure (0.7%); 4 patients had missing data due lost to follow up (3.0%) and 5 patients discontinued 3D/2D regimen (3.7%): 4 due to severe adverse events (including 3 deaths) and 1 patient´s decision.These results have shown that 3D/2D regimens are effective and tolerable in patients with advanced CKD including those in dialysis with GT 1 or 4 chronic HCV mono-infection and HIV/HCV coinfection in a real-life cohort. The overall SVR12 rates were 92.6% (ITT) and 99.2% (mITT) without clinically relevant changes in eGFR until 12 weeks post-treatment. These results are consistent with those reported in clinical trials

The etiology, incidence, and impact of preservation fluid contamination during liver transplantation

The role of contaminated preservation fluid in the development of infection after liver transplantation has not been fully elucidated. To assess the incidence and etiology of contaminated preservation fluid and determine its impact on the subsequent development of infection after liver transplantation, we prospectively studied 50 consecutive liver transplants, and cultured the following samples in each instance: preservation fluid (immediately before and at the end of the back-table procedure, and just before implantation), blood, and bile from the donor, and ascitic fluid from the recipient. When any culture was positive, blood cultures were obtained and targeted antimicrobial therapy was started. We found that the incidence of contaminated preservation fluid was 92% (46 of 50 cases of liver transplantation per year), but only 28% (14/50) were contaminated by recognized pathogens. Blood and bile cultures from the donor were positive in 28% and 6% respectively, whereas ascitic fluid was positive in 22%. The most frequently isolated microorganisms were coagulase-negative staphylococci. In nine cases, the microorganisms isolated from the preservation fluid concurred with those grown from the donor blood cultures, and in one case, the isolate matched with the one obtained from bile culture. No liver transplant recipient developed an infection due to the transmission of an organism isolated from the preservation fluid. Our findings indicate that contamination of the preservation fluid is frequent in liver transplantation, and it is mainly caused by saprophytic skin flora. Transmission of infection is low, particularly among those recipients given targeted antimicrobial treatment for organisms isolated in the preservation fluid
