Figure 2

Reduced serum sphingosine level in COVID-19 patients, is not associated with the diseases’ severity. LC–MS/MS measurements for (A) Sphingosine (Sph), (B) dihydro-sphingosine (dhSph), (C) sphingosine 1-phosphate (Sph-1p), and (D) dihydro-sphingosine 1-phosphate (dhSph-1p). LC–MS/MS ceramide (Cer) measurements for (E) C20:4-Cer, and (F) C26:1 Cer. (G,H) Sph (G) and dhSph (H) levels of symptomatic COVID-19 patients in male and female patients. Pos asymptomatic positive antibody test (n = 8), E enrolled at time of diagnosis (n = 60), M1 one month of recovery (n = 59). Data are means of ± SEM, and P < 0.05 is considered significant.
