The analysis of plasma levels across the follow-up showed that KS/HIV patients with CT increased the PDL-1 level at W4 [560.2 pg/mL (477.3–611.0), p = 0.0145)] and W12 [474.3 pg/mL (362.0–1364.0), p = 0.0330] compared to baseline [157.3 pg/mL (138.0–468.0)]. Here, CD274 is linked to Kaposi's sarcoma.
