Abstract

Peripheral blood mononuclear cells (PBMC) mitochondrial respiration was measured ex vivo from participants without a history of COVID (n = 19), with a history of COVID and full recovery (n = 20), and with PASC (n = 20). Mean mitochondrial basal respiration, ATP-linked respiration, maximal respiration, spare respiration capacity, ATP-linked respiration, and non-mitochondrial respiration were highest in COVID + PASC+ (p ≤ 0.04). Every unit increase in non-mitochondrial respiration, ATP-linked respiration, basal respiration, spare respiration capacity, and maximal respiration increased the predicted odds of PASC between 1 % and 6 %. Mitochondrial dysfunction in PBMCs may be contributing to the etiology of PASC.

SARS-CoV-2 感染急性后遗症患者外周血单核细胞线粒体呼吸的改变。

对无 COVID 病史（19 人）、有 COVID 病史但完全康复（20 人）和 PASC（20 人）的参与者的外周血单核细胞（PBMC）线粒体呼吸进行了体外测量。COVID + PASC+ 的线粒体平均基础呼吸量、ATP 连接呼吸量、最大呼吸量、剩余呼吸量、ATP 连接呼吸量和非线粒体呼吸量最高（p ≤ 0.04）。非线粒体呼吸、ATP 链接呼吸、基础呼吸、剩余呼吸能力和最大呼吸每增加一个单位，PASC 的预测几率就会增加 1% 到 6%。PBMC 线粒体功能障碍可能是 PASC 的病因之一。
