Table 2 Concentrations of neopterin and amino acids from the study population divided into two groups based on disease severity
From: Serum neopterin levels in relation to mild and severe COVID-19
Mild (n = 15) Mean (SD) | Severe (n = 19) Mean (SD) | p-value | |
|---|---|---|---|
Days since onset | 10.2 (9.0) | 11.7 (5.8) | |
Neopterin, nmol/L | 16.9 (11.0) | 42.0 (18.2) | p < 0.0001 |
Tryptophan, μmol/L | 56.3 (11.6) | 31.9 (13.0) | p < 0.0001 |
Kynurenine, μmol/L | 2.6 (0.7) | 4.3 (1.4) | p < 0.0001 |
KYN/TRP *1000 | 47.5 (15.1) | 163.4 (117.5) | p < 0.0001 |
IFN-y, pg/mL | 6.7 (5.0) | 21.4 (20.8) | p < 0.001 |
