Sphingosine, sphinganine and their phosphate derivatives during acute HCV infection. Sphingosine levels on follow-up were significantly upregulated in patients unable to clear HCV compared both to patients with spontaneous or subsequent therapy-induced resolution of HCV infection ((A), p = 0.02 and p = 0.013, respectively). Sphinganine levels were significantly elevated upon chronification of HCV infection on follow-up ((B), p = 0.006), while patients with subsequent SVR after antiviral treatment showed a significant longitudinal reduction of S1P levels ((C), ** p < 0.01). No significant difference in dhS1P levels was observed (D). Statistical significance between baseline and follow-up is indicated by asterisks (*). S1P: sphingosine 1 phosphate; dh: dihydro; SC: spontaneous clearance; SVR: sustained viral response; BSL: baseline; FU: follow-up; cHCV: chronic HCV.
