Respuesta al tratamiento inmunosupresor de pacientes con hepatitis autoinmune

Introducción: La respuesta al tratamiento inmunosupresor en la hepatitis autoinmune influye en el curso clínico de la enfermedad y se asocia a mayor sobrevida. Objetivo: Describir la respuesta al tratamiento inmunosupresor en pacientes con hepatitis autoinmune. Método: Se realizó un estudio descriptivo, longitudinal, ambispectivo, en 32 enfermos con hepatitis autoinmune, los cuales recibieron tratamiento inmunosupresor con evaluación de la respuesta a los 6 meses. Las variables incluidas fueron: tipo de hepatitis autoinmune, forma de presentación, forma de debut y respuesta al tratamiento. Se utilizaron medidas descriptivas de resumen: media y desviación estándar para variables cuantitativas y porcentaje para las variables cualitativas. Para estimar la función de supervivencia se utilizó la curva de Kaplan-Meier y Log-rank para la comparación de medias. Resultados: El 71,9 % de los enfermos estaban con cirrosis en el momento del diagnóstico. Los 13 pacientes con remisión bioquímica permanecieron sin progresión en la evaluación actual. La supervivencia en los pacientes respondedores fue del 100 % y en los no respondedores de 47,5 % a los 10 años de seguimiento. Conclusiones: La respuesta al tratamiento inmunosupresor tiene un impacto positivo en la no progresión de la hepatitis autoinmune y se asoció a mayor supervivencia.

Introduction: The response to immunosuppressive treatment in autoimmune hepatitis influences the clinical course of the disease and is associated with a longer survival. Objective: Describe the response to immunosuppressive treatment in patients with autoimmune hepatitis. Method: A descriptive, longitudinal, ambispective study was carried out in 32 patients with autoimmune hepatitis, who received immunosuppressive treatment with response evaluation at 6 months. The variables included were: type of autoimmune hepatitis, form of presentation, form of onset, and response to treatment. Descriptive summary measures were used: mean and standard deviation for quantitative variables and percentage for qualitative variables. To estimate the survival function, the Kaplan-Meier curve and Log-rank were used to compare means. Results: 71.9 % of the patients were already cirrhotic at the time of diagnosis. The 13 patients with biochemical remission, remained without progression in the current evaluation. Survival in responding patients was 100 %, while in non-responders it was 47.5% at 10-year follow-up. Conclusions: The response to immunosuppressive treatment has a positive impact on the non-progression of autoimmune hepatitis and was associated with greater survival.

Effect of symbiotic fermented milk together with conventional therapy in the eradication treatment of Helicobacter pylori.

Helicobacter pylori (H. pylori) infection is associated with various gastrointestinal diseases and is the dominant microorganism in gastric microbiota. There are multiple therapeutic combinations used with uneven results for eradication. Studies have been carried out with some strains of Lactobacillus (L) that support its preponderant role in the treatment of infection and reduction of inflammation.

Endoscopic retrograde cholangiopancreatography and carbohydrate antigen 19-9 in the differential diagnosis of biliary strictures.

INTRODUCTION: bile-duct strictures include a wide spectrum of benign and malignant diseases. OBJECTIVE: to determine the usefulness of endoscopic retrograde cholangio-pancreatography (ERCP) and circulating carbohydrate antigen 19-9 (CA 19-9) for the differential diagnosis of biliary strictures. METHOD: an observational, prospective, cross-sectional study was performed in 75 patients with biliary stricture diagnosed by ERCP between October 2018 and January 2020. The variables included type of biliary stricture as diagnosed by ERCP, biliary cytology, and CA 19-9 levels. For the statistical analysis, descriptive statistics were used according to type of variable. The relationships between them was analyzed using Pearson's chi-square and Fisher's exact probability tests, assuming differences were significant when p < 0.05. The cut-off point for CA 19-9 was calculated using the ROC curve, and Cohen's kappa index was used to measure concordance between diagnostic methods. RESULTS: cytology was positive in 51 (68 %) patients with biliary stenosis. Mean age was 63 years. Acute cholangitis predominated in malignant strictures (93.7 %). There was agreement between cytology and the cut-off value calculated for CA 19-9 of 85.4 U/mL, with a kappa agreement index of 0.332 (p = 0.004), and between ERCP and cytology, with a kappa concordance index of 0.701 (p < 0.001). CONCLUSIONS: a serum CA 19-9 value higher than 85.4 U/mL is highly related to neoplastic biliary stenosis.
