ABSTRACT
Herbs are commonly used worldwide for the treatment of various diseases, constituting a multi-billion dollar market. Unfortunately, hepatotoxicity induced by herbs is also common. The true incidence and prevalence are not known. There is need for more strict regulations andexperimental and pre-clinical studies regarding its efficacy and safety. There is no gold standard for the diagnosis of herbs-induced liver injury (HILI) and it constitutes a diagnostic challenge for the clinician, whereestablishing causality could be cumbersome. Clinical presentation varies from asymptomatic cases with mildly abnormal liver tests to fulminant liver failure requiring liver transplantation. In this review, we will discuss the epidemiology, clinical manifestations, challenges and diagnostic approach of HILI and will also present some exemplary cases from the University of Miami, Division of Hepatology.
Las hierbas y productos derivados son comúnmente usados alrededor del mundo para el tratamiento de varias enfermedades, constituyendo un mercado multibillonario. Desafortunadamente, hepatotoxidad inducida por estos productos también es común. Existe la necesidad de regulaciones más estrictas, y de estudios experimentales y pre-clínicos acerca de su eficacia y seguridad. No existe un gold-standard para el diagnóstico de injuria hepática inducida por hierbas (HILI), constituyendo un reto diagnóstico para el clínico, donde el establecer una relación de causalidad puede resultar muy difícil. La presentación clínica puede variar desde casos asintomáticos con enzimas hepáticas levemente elevadas hasta casos de falla hepática fulminante requiriendo transplante hepático. En esta revisión, discutiremos brevemente la epidemiologia, manifestaciones clínicas, retos y aproximación diagnostica de la injuria hepática inducida por hierbas y finalmente mostraremos algunos casos ejemplares extraídos de nuestro archivo en la División de Hepatología de la Universidad de Miami.
