ABSTRACT
BACKGROUND AND AIMS: We aimed to characterize the epidemiologic and comorbidities profiles of patients with chronic Hepatitis D (CHD) followed in clinical practice in Italy and explored their interferon (IFN) eligibility. METHODS: This was a cross-sectional study of the PITER cohort consisting of consecutive HBsAg-positive patients from 59 centers over the period 2019-2023. Multivariable analysis was performed by logistic regression model. RESULTS: Of 5,492 HBsAg-positive enrolled patients, 4,152 (75.6%) were screened for HDV, 422 (10.2%) were anti-HDV positive. Compared with HBsAg mono-infected, anti-HDV positive patients were more often younger, non-Italians, with a history of drug use, had elevated alanine transaminase (ALT), cirrhosis, or hepatocellular carcinoma (HCC). Compared with Italians, anti-HDV positive non-Italians were younger (42.2% age≤40 years vs. 2.1%; p<0.001), more often females (males 43.0% vs. 68.6%; p<0.001) with less frequent cirrhosis and HCC. HDV-RNA was detected in 63.2% of anti-HDV-positive patients, who were more likely to have elevated ALT, cirrhosis, and HCC. Extrahepatic comorbidities were present in 47.4% of anti-HDV positive patients and could affect the eligibility of IFN-containing therapies in at least 53.0% of patients in care. CONCLUSIONS: CHD affects young, foreign-born patients and older Italians, of whom two-thirds had cirrhosis or HCC. Comorbidities were frequent in both Italians and non-Italians and impacted eligibility for IFN.
ABSTRACT
HCV infection is still a major burden worldwide, and most countries are not on track to meet the WHO 2030 elimination goal. The current challenge is to identify individuals to be treated. In this study, we will describe the trend of new DAA prescriptions and the changes over time in terms of the characteristics of patients starting antiviral therapy in our unit. Data of 1646 hepatitis C patients who started therapy during the period of 2015-2022 regarding annual number of prescriptions, age, gender, nationality, HCV genotype, provenance, and liver disease severity were analyzed. We observed a peak in the number of new prescriptions in 2018 and a downward trend starting in 2019. Patients from the general population, centers for addictions, and prison differed significantly. The mean age in the general population remained above 60 years, the percentage of patients from centers for addictions and prison increased and, after 2016, there was no significant change in the percentage of patients with F3-F4 fibrosis. As HCV screening and linkage-to-care pathways seem to be already well implemented and successful in centers for addictions and in prisons, efforts need to be focused on those of older age in the general population. To carry this out, the more structured involvement of different health professionals must be figured out.
