P>HAdV infection is a dangerous complication after pediatric SCT. In this study, we aimed at determining the cytokine profile in plasma samples in case of HAdV infection after SCT to gain more knowledge about the HAdV-specific immune response. In this prospective study, 47 pediatric SCT recipients were included in three yr. By using particle-based MIA, 17 different cytokines were analyzed in 41 plasma samples of patients with a localized HAdV infection (presence of HAdV in feces, urine or throat detected by culture) and patients with invasive HAdV infection (HAdV viremia in blood, detected by PCR). In patients with invasive HAdV infection, but not in patients with localized HAdV infection, the pro-inflammatory cytokines IL1 beta, IL6, IL8, IL12, IFN gamma, TNF alpha, and also IL17, MIP1 alpha, OSM, and IP10 were produced. The simultaneous release of the cytokines IL1 beta, IL17, IL18, OSM, MIP1 alpha, and IP10 was related to invasive HAdV infections. We also show that cytokine signatures can be helpful to differentiate invasive HAdV infection from GvHD and EBV infections. In conclusion, after SCT, children with invasive HAdV infection have a different cytokine profile compared with patients with a localized HAdV infection.
