COVID-19 pandemic started in December 2019, and is a worldwide health disaster today, pulmonary fibrosis and cytokine storm are two major complications in COVID-19 patients which can decrease life quality after recovery, and cause death. Histamine effects on the immune system through 4 histamine receptors. The function pattern of histamine 4 receptor has many similarities to COVID-19 pathogenesis pattern.H4R antagonists prevent lung fibrosis in bleomycine-induced lung fibrosis murine models, it can reduce TNF-α and IL-6 secretion in several immunemediated diseases such as asthma, colitis and dermatitis.H4R stimulation also decreases IL-12 which is not detected to be high in COVID-19 patients.TH- 17 acts as an important inflammatory effector in COVID-19 pathogenesis, through IL-17 secretion which results in TNF-α and IL-6 secretion, and also IL-17 promotes tissue remodeling..
