The changing characteristics of patients infected with chronic hepatitis C virus from 2014 to 2019: Real-world data from the German Hepatitis C-Registry (DHC-R).

The number of patients diagnosed with hepatitis C virus (HCV) is markedly higher than the number initiating treatment indicating gaps in the care cascade, likely centred around reaching at-risk populations. Understanding changing characteristics of patients with HCV allows for targeted programs that increase linkage to care. We investigated changes in demographic and clinical characteristics of patients registered in the German Hepatitis C-Registry (DHC-R) from 1 January 2014 to 31 December 2019. The DHC-R is an ongoing, noninterventional, multicentre, prospective, observational cohort registry including 327 German centres. Patient characteristics were analysed over time in 7 phases for all patients completing a screening visit. Overall, 14,357 patients were enrolled. The percentage of treatment-naïve/non-cirrhotic patients increased from 34.4% in phase 1 (1 January-31 December 2014) to 68.2% in phase 7 (1 August-31 December 2019). The proportion of migrants, alcohol users, people who inject drugs, and those receiving opiate substitution therapy increased in later registry phases. Most patients (60.1%) were receiving comedication at baseline. The most prescribed comedications were drugs used to treat opioid dependence which increased from 9.2% in phase 1 to 24.0% in phase 7. The patients' mean age decreased from 52.3 years in phase 1 to 48.7 years in phase 7. From 2014 to 2019, the proportion of at-risk patients enrolling in the registry increased. To eliminate viral hepatitis as a major public health threat, a continued commitment to engaging underserved populations into the HCV care cascade is needed.

BACKGROUND: Healthcare services were faced with unprecedented challenges due to the COVID-19 pandemic and its associated lockdown regulations. In order to analyse the influence of the pandemic on the healthcare of patients with chronic hepatitis C in Germany, we carried out a structured questionnaire among all centres participating in the German Hepatitis C-Registry (DHC-R). METHODS: 320 centres of the DHC-R were invited to participate in an online survey. Of these, 74 centres had included ≥ 5 patients in the last 12 months. FINDINGS: A fully answered questionnaire was sent back by 64 centres. Due to the lockdown regulations, 11 % of the centres had stopped their regular consultation between March and May 2020; 58 % had reduced the consultations and 32 % did not change the consultations. More than 50 % of the appointment cancellations were done by the patients. 52 % of the centres offered a new or additional telephone consultation and 17 % offered a new video consultation. Between March and May 2020, the number of patients newly treated with antivirals was markedly lower when compared with the same period in 2019. All centres had returned to their usual consultation procedures in July 2020. Almost 80 % indicated that there were no significant limitations in patient's healthcare. However, 22 % of the centres stated that liver decompensation was diagnosed late and 9.4 % stated that diagnosis of hepatocellular carcinoma was delayed. An adequate amount of personal protective equipment (including disinfectants) was available in 56 % of the centres. Official information by public healthcare authorities was considered sufficient by 63 % of the centres. SUMMARY: Diagnosis, therapy and monitoring of patients with chronic hepatitis C were impaired during the COVID-19 pandemic. Nevertheless, the majority of the centres did not see healthcare problems for these patients in the medium and long term. However, the fact that the diagnosis of liver decompensations with potential lethal consequences was delayed in a considerable number of patients causes major concern.
