ABSTRACT
Introdução: lesão hepática induzida por drogas (DILI) é responsável por um amplo espectro de lesão hepática. Clinicamente, esses eventos são apresentados de várias formas e, para alcançar um diagnóstico diferente, outras causas de lesões devem ser excluídas. Objetivo: identificar e caracterizar casos de hepatotoxicidade induzida por medicamentos, fitoterápicos e suplementos alimentares em Hospital Universitário no Brasil. Metodologia: estudo observacional, retrospectivo. Os dados foram coletados em prontuários do Hospital Universitário, entre agosto de 2009, em agosto de 2014. A causalidade das reações medicamentosas suspeitas foi avaliada pelo Conselho de Organizações Internacionais de Ciências Médicas (CIOMS). Resultados: foram selecionados 30 casos suspeitos, 50% do sexo feminino e média de 39 anos. As classes terapêuticas mais comuns foram: anti-infecciosos; agentes antineoplásicos; drogas do sistema nervoso central, esteroides anabolizantes e suplementos herbáceos e dietéticos (HDS). Lesão colestática ou mista foi observada em 73% desses casos; 60% eram altamente prováveis, de acordo com o CIOMS. Conclusão: DILI é causada por uma grande variedade de drogas, suplementos dietéticos e suplementos dietéticos. Anti-infecciosos e quimioterapia foram responsáveis por grande parte da resposta.
Background: drug Induced Liver Injury (DILI) is responsible for wide spectrum of liver injury. Clinically, these events are presented in various forms and for reaching a different diagnosis other injury causes must be excluded. Aim: identify and characterize cases of hepatotoxicity induced by drugs, herbal and dietary supplements in University Hospital in Brazil. Methodology: observational and retrospective study. Was collected in records of University Hospital, between August 2009 at August 2014. The causality of the drug reactions suspected were evaluated Council for International Organizations of Medical Sciences (CIOMS). Results: we selected 30 suspected cases, 50% was female and average was 39 years. the therapeutic classes most common was: anti-infectives; antineoplastic agents; central nervous system drugs, anabolic steroid and herbal and dietary supplements (HDS). Cholestatic or mixed injury was observed in 73% these cases; 60% were highly probable, according to CIOMS. Conclusion: DILI is caused by a wide variety of drugs, dietary supplements and dietary supplements. Anti-infectives and chemotherapy were responsible for much of the response.

Chemical and Drug Induced Liver InjuryABSTRACT
The consumption of botanicals for therapeutic purposes has increased significantly in recent years. Drug-induced liver disease (DILI) is a frequent cause of acute liver injury, around 50% in the United States, and about 1% is secondary to the use of phytotherapeuticals and herbal supplies. Ruellia bahiensis, a plant species of the Acanthaceae family, is a tropical plant distributed in Northeastern Brazil. In folk medicine in the state of Bahia, the species is known as "mãe-boa" and is commonly used. L.S.S, a 23-year old, female, patient was admitted at University Hospital of Bahia-Brazil with signs and symptoms of acute hepatitis. She had made daily use of an herbal supply popularly known as "mãe-boa" for at least two years prescribed by a physician. Diagnostic investigation was negative for viral and autoimmune hepatitis, leptospirosis, dengue, and CMV (cytomegalovirus). The patient had to undergo liver transplantation. Explant revealed massive hepatic necrosis. According to histological findings, and after exclusion of other etiologies, liver damage was assigned to herbal supply. The prolonged use of Ruellia bahiensis infusions may have caused the liver dysfunction.

Introduction and aim. Non-cirrhotic idiopathic portal hypertension (NCIPH), also known as hepatoportal sclerosis (HPS) is a disease of uncertain etiology. However, various pathophysiological mechanisms has been postulated, including chronic or recurrent infections and exposure to drugs or toxins. In this context, it appears to be of multifactorial etiology or resulting from a portal vascular endothelium aggression. It is important to consider whether the use of dietary supplements and herbs can trigger or contribute to the occurance of HPS. We report a possible association of HPS with the consumption of herbals and / or dietary supplements. MATERIAL AND METHODS: We describe two cases of HPS in patients without known etiology causes associated with this disease. RESULTS: Both patients were females who were diagnosed with HPS following the consumption of Herbalife® products and putative anorexigenic agents in the form herbals infusions. Image-based analysis and the assessment of the histopathological alterations found in the livers confirmed the diagnosis. The histopatological analysis of liver samples from both patients showed portal tracts enlarged by fibrosis with disappearance or reduction in the diameter of the portal vein branches. In many portal tracts, portal veins branches were replaced by aberrant thin-walled fendiforme vessels. The bile ducts and branches of the hepatic artery show normal aspects. CONCLUSION: After the exclusion of other etiologic factors and a comprehensive analysis of clinical history, consumption of Herbalife® products and anorexigenic agents was pointed-out as a puttative predisposing factor for the development of the disease.
