Background
Viral infection can compound the severity of pre-existing inflammation caused by underlying diseases. For those with a chronic, immune-related condition such as diabetic foot ulcers (DFUs), the coronavirus disease (COVID-19) serves to exacerbate the inflammatory burden. Serum levels of intracellular adhesion molecule-1 (ICAM-1), a primary mediator of cell adhesion express in the inflammatory process, are often used to indicate the gravity of all inflammatory conditions. Therefore, the
Conclusion
ICAM-1 serum levels represent an additional, initial screening marker for COVID-19.
Methods
20 patients with DFUs were screened for COVID-19 and then divided into COVID-19 positive and negative groups according to the
Results
Of the 20 patients included in this study, 55% were male (n = 11) and 45% were female (n = 9). The mean age was 52.9 ± 1.9 years. ICAM-1 levels in patients with DFU in the COVID-19-positive group were significantly higher than those in the COVID-19-negative group (median 317.2 vs 149.2, respectively; p < 0.001). Serum levels of ICAM-1 reduced significantly in patients with DFU in the COVID-19-positive group were significantly higher than those in the COVID-19-negative group after debridement (median 312.5 vs 130.3; p < 0.001).
