Hepatitis C virus micro-elimination in vulnerable populations before and during a global pandemic.

OBJECTIVE: to analyze a hepatitis C virus (HCV) microelimination strategy targeting vulnerable populations and the influence of the pandemic on its maintenance and outcomes. METHODS: in 2018, the Hepatology Unit implemented an HCV microelimination strategy for patients attending drug addiction care centers and Psychiatry Units such as the Alcoholism Treatment Unit. These centers reported suspected or confirmed cases of HCV infection directly to the hepatologists, who, after reviewing the clinical records, cite those patients if necessary. RESULTS: from June 2018 to February 2020, hepatologists were consulted on 37 anti-HCV positive patients, 31 of them were from Drug Addiction Care Centers, 5 from the Alcoholism Disorders Unit and 1 from the Department of Psychiatry. Fibrosis stage: F0-F1, 18 (50%); F2, 9 (25%); F3, 2 (4.2%); F4, 8 (20.8%). Female sex, 6 (16.7%). Required attending: Yes, 27 (73%). 25 (92.6%) went. Outpatient consultation: 10 (27%). Required treatment: 19 (51.3%). Sustained virological response: 19 (100%). Fibrosis stage of treated patients: F0-F1, 13 (68%); F2, 2 (11%); F3, 1 (5%); F4, 3 (16%). Patients from the Psychiatry Department during 2021: 11. 9 (82%) do not need to attend; 2 (18%): their situation is unknown. CONCLUSIONS: sustained communication with centers that care for populations at risk of active HCV infection is needed to detect cases, increase adherence to treatment, and rescue patients who require screening for hepatocarcinoma.

Perivascular epithelioid cell tumor of the ileum. A case report.

Perivascular epithelioid cell tumors (PEComa) are tumors of perivascular epithelioid cells with immunohistochemical features of smooth muscle and melanocytic tumors. The PEComa of the gastrointestinal tract is rare. The treatment is surgical, although there are data that suggest a good response to rapamycin.
