RESUMO
Background: Since the introduction of direct-acting antivirals, thousands of chronic hepatitis C patients have been successfully treated. However, vulnerable populations have a higher prevalence of hepatitis C virus (HCV) infection and face barriers that impede their access to antivirals. We carried out an HCV microelimination program focused on vulnerable population groups in Malaga. Methods: People in drug addiction treatment centers and homeless shelters in Malaga who participated in the program between October 2020 and October 2021 were included. After providing participants with educational information on HCV, a dry drop test (DDT) was used to collect blood for subsequent screening for HCV infection. The participants who were diagnosed with HCV infection were scheduled for comprehensive healthcare assessments, including blood tests, ultrasonography, elastography, and the prescription of antivirals, all conducted in a single hospital visit. Sustained viral response (SVR) was analysed 12 weeks after end of treatment. Results: Of the 417 persons invited to participate, 271 (65%) agreed to participate in the program. These participants were screened for HCV infection and 28 of them were diagnosed with HCV infection (10%). These hepatitis C-infected patients had a mean age of 53 ± 9 years; 86% were males and 93% were or had been drug users. Among 23 patients with HCV infection, HCV genotype 1a predominated (74%). Medical exams showed that 19% (4/21) had advanced fibrosis (F3-4), and 5% (1/21) had portal hypertension. Finally, 23 infected patients received treatment with glecaprevir/pibrentasvir or sofosbuvir/velpatasvir and SVR was confirmed in 22 patients (96%). Conclusions: Drug users and homeless people have a higher prevalence of HCV infection than the general population. The microelimination program with educational activity and screening tools achieved a high participation rate, easy healthcare access, and a high rate of SVR despite the SARS-CoV-2 pandemic.
RESUMO
En el año 2016 se detectó en la provincia de Málaga un brote de hepatitis A en pacientes con características epidemiológicas especiales, con un predominio de sujetos del sexo masculino. Presentamos 51 casos de hepatitis A aguda con una media de edad de 35,7 años, el 90% varones, con un 55% de casos que reconocían haber mantenido relaciones sexuales con otros hombres en los últimos dos meses. La mitad de ellos requirieron ingreso hospitalario por coagulopatía significativa en el momento del diagnóstico, sin evolución a fallo fulminante, ni encefalopatía en ningún caso. Cuatro casos presentaban ascitis al diagnóstico. Este brote se suma a otros dos publicados en Reino Unido y Holanda con un número de casos similar y epidemiológicamente muy parecidos, lo cual refuerza la importancia de la vigilancia epidemiológica y la necesidad de vacunación en esta población de riesgo, así como de campañas informativas a la población para prevenir la enfermedad
In 2016, an outbreak of hepatitis A was identified in the Malaga province among patients with specific epidemiological characteristics, which were predominantly males. This is a report of 51 subjects with acute hepatitis A and a mean age of 35.7 years, 90% were male and 55% of cases were men who had had sex with other men within the last two months. Half of them required hospitalization for significant coagulopathy at diagnosis and no cases progressed to fulminant failure or encephalopathy. Four patients had ascites at the time of diagnosis. This outbreak adds to those reported in the United Kingdom and the Netherlands with a similar number of cases and epidemiology. These studies highlight the importance of epidemiological surveillance, the need for vaccination in this particular at risk population and the need for informative campaigns in order to prevent this disease
