To characterize viral hepatitis co-infections in a cohort of immigrants living in southern Italy. In a prospective multicenter study, all undocumented immigrants and low-income refugees consecutively evaluated for a clinical consultation at one of the five first-level clinical centers in southern Italy from January 2012 to February 2020 were enrolled. All subjects included in the study were screened for hepatitis B surface antigen (HBsAg), anti-hepatitis C virus (HCV) and anti-HIV; the HBsAg-positive were screened also for anti-delta. Of the 2923 subjects enrolled, 257 (8%) were HBsAg-positive alone (Control group B), 85 (2.9%) only anti-HCV-positive (Control group C), 16 (0.5%) HBsAg/anti-HCV-positive (Case group BC), and 8 (0.2%) HBsAg/anti-HDV-positive (Case group BD). Moreover, 57 (1.9%) subjects were anti-HIV-positive. HBV-DNA positivity was found less frequently in the 16 subjects in Case group BC (43%) and in the 8 in Case group BD (12.5%) than in the 257 in Control group B (76%; p = 0.03 and 0.0000, respectively). Similarly, HCV-RNA positivity was more frequent in Case group BC than in Control group C (75% vs. 44.7% p = 0.02). The subjects in Group BC had a lower prevalence of asymptomatic liver disease (12.5%) than Control group B (62.2%, p = 0.0001) and Control group C (62.3%, p = 0.0002). Conversely, liver cirrhosis was more frequently identified in Case group BC (25%) than in Control groups B and C (3.11% and 2.35%, p = 0.0000 and 0.0004, respectively). The present study contributes to the characterization of hepatitis virus co-infections in the immigrant population.

Abstract

To characterize viral hepatitis co-infections in a cohort of immigrants living in southern Italy. In a prospective multicenter study, all undocumented immigrants and low-income refugees consecutively evaluated for a clinical consultation at one of the five first-level clinical centers in southern Italy from January 2012 to February 2020 were enrolled. All subjects included in the study were screened for hepatitis B surface antigen (HBsAg), anti-hepatitis C virus (HCV) and anti-HIV; the HBsAg-positive were screened also for anti-delta. Of the 2923 subjects enrolled, 257 (8%) were HBsAg-positive alone (Control group B), 85 (2.9%) only anti-HCV-positive (Control group C), 16 (0.5%) HBsAg/anti-HCV-positive (Case group BC), and 8 (0.2%) HBsAg/anti-HDV-positive (Case group BD). Moreover, 57 (1.9%) subjects were anti-HIV-positive. HBV-DNA positivity was found less frequently in the 16 subjects in Case group BC (43%) and in the 8 in Case group BD (12.5%) than in the 257 in Control group B (76%; p = 0.03 and 0.0000, respectively). Similarly, HCV-RNA positivity was more frequent in Case group BC than in Control group C (75% vs. 44.7% p = 0.02). The subjects in Group BC had a lower prevalence of asymptomatic liver disease (12.5%) than Control group B (62.2%, p = 0.0001) and Control group C (62.3%, p = 0.0002). Conversely, liver cirrhosis was more frequently identified in Case group BC (25%) than in Control groups B and C (3.11% and 2.35%, p = 0.0000 and 0.0004, respectively). The present study contributes to the characterization of hepatitis virus co-infections in the immigrant population.
