Prepandemic Metabolic Correlates of Coronavirus Disease 2019 (COVID-19) Severity and Long COVID Incidence in People Living With HIV

J Infect Dis. 2024 Oct 16;230(4):912-918. doi: 10.1093/infdis/jiae362.

Abstract

Host metabolic dysregulation, especially in tryptophan metabolism, is intricately linked to coronavirus disease 2019 (COVID-19) severity and its postacute sequelae (long COVID). People living with human immunodeficiency virus (HIV; PLWH) experience similar metabolic dysregulation and face an increased risk of developing long COVID. However, whether preexisting HIV-associated metabolic dysregulations contribute in predisposing PLWH to severe COVID-19 outcomes remains underexplored. Analyzing prepandemic samples from PLWH with documented postinfection outcomes, we found specific metabolic alterations, including increased tryptophan catabolism, predicting an elevated risk of severe COVID-19 and the incidence of long COVID. These alterations warrant further investigation for their potential prognostic and mechanistic significance in determining COVID-19 complications.

Keywords: COVID-19; HIV; long COVID; metabolites; tryptophan.
