Similar results were observed in the study by Peluso et al.: higher levels of IL-6 and IFN-γ-induced protein 10 (IP-10) during early recovery from COVID-19 were associated with subsequent development of PASC; in addition, among patients with PASC, IL-6 showed a trend towards from early to late recovery [133]. This evidence concerns the gene CXCL10 and long COVID-19.
