The mitochondrial membrane potential (Δ Ψ m ) is a parameter often used to determine mitochondrial function; therefore, it can be used to determine the integrity and functionality of cells. A decrement of Δ Ψ m is implicated in several inflammatory‐related pathologies, such phenomena can be related to COVID‐19 infection. The present work aimed to compare the Δ Ψ m in leucocytes (human PBMCs; HPBMC) isolated from healthy control (HC) subjects, patients with COVID‐19 (C‐19), recovered subjects at 40 ± 13 (R1) and 335 ± 20 (R2) days after infection (dai). Obtained data showed that Δ Ψ m decreased in HPBMC of subjects with C‐19, R1, and R2 compared with HC. When analyzing the Δ Ψ m data by sex, in females, a significant decrease was observed in R1 and R2 groups versus HC. Regarding men, a significant decrease of Δ Ψ m was observed in R1, with respect to HC, contrary to R2 group, who reestablished this parameter. Obtained results suggest that the loss of Δ Ψ m could be related to the long‐COVID.
