TNF and infection: The median TNF-α level above QL (121.4, IQR: 66.5–205.5 pg/mL) in plasma samples from the patients with infection markers and elevated median HHV-7 load (>10 copies/106 cells) was significantly higher (p = 0.0001, KW) in comparison to the patients without elevated HHV-7 load (<10 copies/106 cells) (15.0, IQR: 10.6–27.5 pg/mL), as well as in comparison to control individuals without HHV infection (p< 0.0001, KW).
