Symptom relief and cytokine modulation by clarithromycin in mild COVID-19 pneumonia: an exploratory, multicenter, randomized-controlled open-label trial (CAME-COVID study). (PubMed, Ther Adv Infect Dis)
Serum inflammatory cytokines, tumor necrosis factor (TNF)-α, granulocyte colony stimulating factor (G-CSF), interleukin (IL)-7, IL-15, and proliferation factors, transforming growth factor (TGF)-α, fibroblast growth factor (FGF)-2, and fms-like tyrosine kinase 3 ligand (Flt3-L), significantly decreased in group A. IL-8 and IFN-γ in nasal drip significantly decreased in both group A and B. Serious adverse events did not increase in CAM groups, though mild gastrointestinal and liver events occurred in group A. CAM is safe and potentially useful for improving partial COVID-related symptoms and exerting immunomodulation during COVID-19 pneumonia.
