People living with HIV, HCV and HIV/HCV coinfection in intensive care in a German tertiary referral center 2014-2019.

Purpose: The epidemiology of HIV-infected individuals on the Medical Intensive Care Units (MICU) has changed after profound progress in treatment of AIDS-defining illnesses and anti-retroviral therapy (ART). Changes of MICU utilization of Hepatitis C (HCV) patients following roll-out of direct-acting antivirals (DAA) are yet to evaluate.
Methods: We performed a retrospective study on all patients with HIV, HIV/HCV and HCV admitted to the MICU of University Hospital Bonn 2014-2019. We assessed sociodemographic data, available clinical data from HIV patients (CDC stage, CD4 + lymphocyte cell count, HIV-1-RNA, ART) and HCV patients (HCV-RNA, stage of liver cirrhosis, treatment history) and outcome.
Results: 237 patients (46 HIV, 22 HIV/HCV, 169 HCV; 168 male, median age 51.3 years) with 325 MICU admissions were included. Admission criteria for HIV patients were infections (39.7% AIDS-associated, 23.8% with controlled HIV-infection) and cardiopulmonary diseases (14.3%). HIV/HCV coinfected patients had infections in controlled/uncontrolled HIV-infection (46.4%), cardiopulmonary diseases and intoxication/drug abuse (17.9% each). Reasons for HCV-mono-infected patients were infections (24.4%), sequelae of liver disease (20.9%), intoxication/drug abuse (18.4%) and cardiopulmonary diseases (15%). 60 patients deceased; most important risk factor was need for mechanical ventilation. The number of HCV-patients admitted to MICU with chronic active disease and sequelae of liver disease decreased while the proportion of patients with completed DAA-treatment increased.
Conclusion: Infections remain the most important reason for MICU admission in patients with HIV and/or HCV infection while non-AIDS related conditions increased. DAA roll-out has a beneficial effect on liver-associated morbidity in HCV patients admitted to MICU.
