    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.

    Insulin resistance is a prevalent condition commonly associated with unhealthy lifestyles. It affects several metabolic pathways, increasing risk of abnormalities at different organ levels. Thus, diverse medical specialties should be involved in its diagnosis and treatment. With the purpose of unifying criteria about this condition, a scientific-based consensus was elaborated. A questionnaire including the most important topics such as cardio-metabolic risk, non-alcoholic fatty liver disease and polycystic ovary syndrome, was designed and sent to national experts. When no agreement among them was achieved, the Delphi methodology was applied. The main conclusions reached are that clinical findings are critical for the diagnosis of insulin resistance, not being necessary blood testing. Acquisition of a healthy lifestyle is the most important therapeutic tool. Insulin-sensitizing drugs should be prescribed to individuals at high risk of disease according to clinically validated outcomes. There are specific recommendations for pregnant women, children, adolescents and older people.
