ABSTRACT

Introducción. La enfermedad hepática grasa no alcohólica (EHGNA) es la hepatopatía crónica más común en el mundo, y en aproximadamente el 10 % de los casos progresará a cirrosis o a carcinoma hepatocelular. La presencia de fibrosis hepática es el mejor predictor de esta progresión, pero su diagnóstico mediante biopsia hepática es invasivo y con riesgo de complicaciones (alrededor del 2,5 %). Existen puntajes no invasivos que se han desarrollado y validado para estadificar la fibrosis, pero no conocemos su rendimiento en la población colombiana. El objetivo de este estudio fue evaluar el desempeño de los puntajes fibrosis-4 (FIB-4), la relación AST/ALT y el índice AST/plaquetas (APRI) para la detección de fibrosis avanzada en pacientes colombianos con EHGNA. Metodología. Estudio observacional tipo transversal de pacientes con EHGNA, que entre 2008 y 2022 tuvieran disponible el resultado de una biopsia hepática. Se hizo una descripción demográfica básica y se calculó el FIB-4, la relación AST/ALT y el APRI con los laboratorios más recientes previos al procedimiento. Posteriormente se calcularon valores de sensibilidad, especificidad, valores predictivos, razones de verosimilitud y área bajo la curva-característica operativa del receptor (AUC-ROC) para los puntos de corte evaluados previamente en la literatura. Resultados. Se incluyeron 176 pacientes, de los cuales el 14,3 % tenían fibrosis avanzada. El FIB-4 presentó el mejor rendimiento con un valor AUC-ROC de 0,74 para el punto de corte de 1,30 y 2,67. En segundo lugar, estuvo la relación AST/ALT con un valor AUC-ROC de 0,68 con el punto de corte de 0,8, y finalmente el APRI con valor AUC-ROC 0,62 con el punto de corte de 1. Conclusión. En la población analizada los tres puntajes tienen menor rendimiento diagnóstico comparado a los resultados reportados en Europa y Japón. El FIB-4 es el único que alcanza una AUC-ROC con rendimiento razonable, con la limitación que 27,4 % obtuvieron un resultado indeterminado.


Introduction. Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease worldwide, with approximately 10% of cases progressing to cirrhosis or hepatocellular carcinoma. Liver fibrosis presence is the best predictor of this progression, yet its diagnosis through liver biopsy is invasive and poses risk of complications. Although non-invasive scoring systems have been developed and validated for fibrosis staging, their performance remains unexplored in the Colombian population. This study aims to assess the efficacy of the fibrosis-4 (FIB-4) score, AST/ALT ratio, and AST to platelet ratio index (APRI) in detecting advanced fibrosis among Colombian NAFLD patients. Methods. This cross-sectional observational study included NAFLD patients with available liver biopsy results from 2008 to 2022. Basic demographic characteristics were described, and FIB-4, APRI, and AST/ALT ratio were calculated using the latest laboratory data before the procedure. Subsequently, sensitivity, specificity, predictive values, likelihood ratios, and the area under the receiver operating characteristic curve (AUC-ROC) were computed for previously assessed cutoff points. Results. A total of 176 patients were included, among whom 14.3% had advanced fibrosis. FIB-4 demonstrated superior performance with an AUC-ROC value of 0.74 for cutoff points of 1.30 and 2.67. Following was the AST/ALT ratio with an AUC-ROC value of 0.68 for cutoff point of 0.8, and finally, APRI with an AUC-ROC of 0.62 for the cutoff point of 1. Conclusion. All three scores have lower diagnostic efficacy compared to results reported in Europe and Japan. FIB-4 is the only one that achieves an acceptable AUC-ROC performance with the limitation that an indeterminate result was obtained in 27,4% of the sample.

ABSTRACT

INTRODUCTION: Defining histological variables that make it possible to establish the activity of Crohn's disease (CD) and predict the patients who may present a higher risk of clinical complications and surgical interventions could lead to timely adjustments in medical therapy and elective surgeries that represent a lower risk of complications. The purpose of the study is to determine the relation between the histopathological findings using the Naini and Cortina (N&C) score, the clinical severity, and the indication for surgery in a group of patients with CD. MATERIALS AND METHODS: Descriptive, retrospective, cross-sectional study of 44 patients diagnosed with CD, treated at the San Vicente Fundación University Hospital in Medellín, Colombia, between 2010 and 2022. RESULTS: Of the 44 patients, 36 ileum samples and 34 colon samples were obtained. Of the patients with inflammatory behavior, 87.5% did not have surgical intervention (P=.022), a value that remained significant in the ileum subgroup (P=.0058). 91.3% of the patients with ileal involvement did not develop perianal disease (P=.01). Granulomas only occurred in two patients with a colon sample (5.8%). In the histological score of N&C both in the ileum and in the colon, no statistically significant differences were obtained in relation to the surgical outcome (P=.34 and P=.054, respectively). CONCLUSION: The histological index of N&C was not a predictor in Crohn's disease (CD) related to the surgical outcome.

ABSTRACT

Resumen La enfermedad de Kikuchi-Fujimoto (EKF) es conocida como una linfadenitis necrotizante histiocítica, tiene una presentación benigna y autolimitada, afecta principalmente a mujeres jóvenes y generalmente resuelve sin tratamiento en los primeros seis meses de los síntomas. Presentamos el caso de una mujer de 48 años quien consultó por un cuadro de dolor abdominal, mialgias y adenopatía cervical al examen físico. Se le encontró en los exámenes paraclínicos anticuerpos antinucleares 1:640, anti DNA de doble cadena asociado a consumo de complemento y anticuerpos anticardiolipina positivos. Se realizó biopsia de ganglio cervical que mostró necrosis cortical y población de histiocitos y linfocitos. Al iniciar el manejo con esteroides y cloroquina se comprobó mejoría franca y posteriormente la paciente fue dada de alta, continuando controles de manera ambulatoria por los servicios de reumatología y medicina interna.


Abstract Kikuchi disease, also known as histiocytic necrotizing lymphadenitis, isa benign and self-limited condition that mainly affects young women andresolve without treatment within six months of symptoms. It was first describedin Japan in 1972 and is more common in Asian population. We report the case of a woman of 48 years who consults for abdominal pain, myalgia, and cervical lymphadenopathy on physical examination. He found himself in the presence of antinuclear antibodies paraclinical 1: 640 positive DNA double chain associated with complement consumption and positive cardiolipin antibodies We perform cervical node biopsy that showed the presence of cortical necrosis and histiocytes and lymphocytes population. When you start handling steroid and chloroquine, a high frank and subsequent improvement was observed, continuing control rheumatology and internal medicine.
