    Idiosyncratic drug-induced liver injury (DILI) caused by xenobiotics (drugs, herbals and dietary supplements) is an uncommon cause of liver disease presenting with a wide range of phenotypes and disease severity, acute hepatitis mimicking viral hepatitis to autoimmune hepatitis, steatosis, fibrosis or rare chronic vascular syndromes. Disease severity ranges from asymptomatic liver test abnormalities to acute liver failure. DILI has been traditionally classified in predictable or intrinsic (dose-related) or unpredictable (not dose-related) mechanisms. Few prospective studies are assessing the real prevalence and incidence of hepatotoxicity in the general population. DILI registries represent useful networks used for the study of liver toxicity, aimed at improving the understanding of causes, phenotypes, natural history, and standardized definitions of hepatotoxicity. Although most of the registries do not carry out population-based studies, they may provide important data related to the prevalence of DILI, and also may be useful to compare features from different countries. With the support of the Spanish Registry of Hepatotoxicity, our Latin American Registry (LATINDILI) was created in 2011, and more than 350 DILI patients have been recruited to date. This position paper describes the more frequent drugs and herbsinduced DILI in Latin America, mainly focusing on several features of responsible medicaments. Also, we highlighted the most critical points on the management of hepatotoxicity in general and those based on findings from our Latin American experience in particular.

    Background: In order to achieve the World Health Organization’s ambitious goal of eliminating hepatitis C (HCV), we must implement innovative strategies to diagnose and treat more patients. Therefore, our study aimed to identify patients with chronic HCV infection who lost follow-up and offer them re-linkage to care and treatment with direct-acting antivirals (DAAs). Methods: We conducted an implementation study of a strategy to contact patients with chronic HCV who were not under regular follow-up in 10 countries from Latin America. Patients with HCV were identified by the international classification of diseases (ICD-9/10) or similar. Medical records were then reviewed to confirm the diagnosis of chronic HCV infection defined as anti-HCV + and detectable HCVRNA. Identified patients who were not under follow-up by a liver specialist were contacted to offer them a medical reevaluation and, eventually, treatment with DAA. Results: A total of 3,709 patients were classified as HCV, of which 367 (9.9%) presented undetectable HCVRNA, and 148 (4.0%) were wrongly coded. Overall, 3,194 (86.1%) individuals were identified with chronic HCV infection, 49,9% were male, median age was 61 years (IQR 51-69); 166 (5.2%) developed hepatocellular carcinoma, and 117 (3.7%) underwent liver transplantation. Advanced liver fibrosis (F3-F4) was present in 1,361 (42.6%) patients. A total of 1,764 (55.2%) patients were under close care. Of these, 1,371 (74.7%) received antiviral treatment, 70 (5.3%) did not achieve sustained virologic response, 314 (17.8%) were not treated for different reasons and 133 (7.5%) died. We identified 1,430 (44.8%) patients who were lost of follow-up, 564 (39.4%) of whom were finally located. Of those contacted, 402 (71.3%) were candidates to receive DAAs, 108 (19.2%) were treated in other institutions, 12 (2.1%) did not wish to be treated, and 42 (7.4%) died (Figure). Globally, in our study 786/3,194 (24.6%) patients were candidates to receive antiviral therapies. Conclusion: In our cohort, 1 out of 4 patients with chronic HCV could be re-linked to care and treated. This strategy impresses to be effective, accessible and, significantly impact on the HCV cascade to cure.

    Nitrofurantoin-induced liver injury: long-term follow-up in two prospective DILI registries
    (2023) Bessone, Fernando; Ferrari, Antonella; Hernandez, Nelia; Mendizabal, Manuel; Ridruejo, Ezequiel; Zerega, Alina; Tanno, Federico; Reggiardo, Maria Virginia; Vorobioff, Julio; Tanno, Hugo; Arrese, Marco; Nunes, Vinicius; Tagle, Martin; Medina-Caliz, Inmaculada; Robles-Diaz, Mercedes; Niu, Hao; Alvarez-Alvarez, Ismael; Stephens, Camilla; Lucena, M. Isabel; Andrade, Raul J.
    Nitrofurantoin is a synthetic antibiotic that is recommended as first-choice treatment for uncomplicated urinary tract infections. The prescription of this drug has increased dramatically, especially in Latin American countries. We described the demographics, clinical characteristics, biochemical features, and outcome of nitrofurantoin-induced liver injury. We analyzed 23 cases from the Latin American DILI Network (LATINDILI) and the Spanish DILI Registry. Causality was assessed with the RUCAM and RECAM scale. Of the 23 DILI cases included in our series, 96% patients were women, and the mean age of the whole cohort was 61 years. The median time of drug exposure was 175 days (interquartile range [IQR] 96-760), with 11 patients who were prescribed nitrofurantoin for more than six months. Hepatocellular damage was the most frequent pattern of liver injury (83%), and nearly half of the patients had an asymptomatic presentation (52%). Neither death nor liver transplantation was documented in this series. Overall, 65% of the patients (n = 15) presented with positive autoantibody titres. The median time to resolution was 81 days (IQR 57-141), and 15 patients (83%) recovered within six months. Five patients (22%) developed nitrofurantoin-induced autoimmune-like hepatitis (NI-AILH), of whom two were characterized by a persistent increase in transaminases that required immunosuppressive treatment to achieve normalization of liver enzymes. Clinicians who prescribe nitrofurantoin should be aware that patients who had taken nitrofurantoin for a long term may be at risk of developing nitrofurantoin-induced autoimmune-like hepatitis.

    Serious liver injury induced by Nimesulide: an international collaborative study
    (2021) Bessone, Fernando; Hernandez, Nelia; Mendizabal, Manuel; Ridruejo, Ezequiel; Gualano, Gisela; Fassio, Eduardo; Peralta, Mirta; Fainboim, Hugo; Anders, Margarita; Tanno, Hugo; Tanno, Federico; Parana, Raymundo; Medina-Caliz, Inmaculada; Robles-Diaz, Mercedes; Alvarez-Alvarez, Ismael; Niu, Hao; Stephens, Camilla; Colombato, Luis; Arrese, Marco; Reggiardo, M. Virginia; Ono, Suzane Kioko; Carrilho, Flair; Lucena, M. Isabel; Andrade, Raul J.
    Nimesulide is a non-steroidal anti-inflammatory drug still marketed in many countries. We aim to analyze the clinical phenotype, outcome, and histological features of nimesulide-induced liver injury (nimesulide-DILI). We analyzed 57 cases recruited from the Spanish and Latin American DILI registries. Causality was assessed by the RUCAM scale. Mean age of the whole case series was 59 years (86% women) with a median time to onset of 40 days. A total of 46 patients (81%) were jaundiced. Nimesulide-DILI pattern was hepatocellular in 38 (67%), mixed in 12 (21%), and cholestatic in 7 (12%) cases. Transaminases were elevated with a mean of nearly 20-fold the upper limit of normality (ULN), while alkaline phosphatase showed a twofold mean elevation above ULN. Total bilirubin showed a mean elevation of 13-fold the ULN. Liver histology was obtained in 14 cases (25%), most of them with a hepatocellular pattern. Median time to recovery was 60 days. Overall, 12 patients (21%) developed acute liver failure (ALF), five (8.8%) died, three underwent liver transplantation (5.3%), and the remaining four resolved. Latency was <= 15 days in 12 patients (21%) and one patient developed ALF within 7 days from treatment initiation. Increased total bilirubin and aspartate transaminase levels were independently associated with the development of ALF. In summary, nimesulide-DILI affects mainly women and presents typically with a hepatocellular pattern. It is associated with ALF and death in a high proportion of patients. Shorter (<= 15 days) duration of therapy does not prevent serious nimesulide hepatotoxicity, making its risk/benefit ratio clearly unfavorable.
