Evidence has emerged regarding an increased risk of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) with worse prognosis in elderly male patients with obesity, and blunted growth hormone (GH) secretion represents a feature of this population subgroup. Here, a comprehensive review of the possible links between GH–insulinlike growth factor 1 axis impairment and coronavirus disease 2019 (COVID‐19) severity is offered. First, unequivocal evidence suggests that immune system dysregulation represents a key element in determining SARS‐CoV‐2 severity, as well as the association with adult‐onset GH deficiency (GHD); notably, if GH is physiologically involved in the development and maintenance of the immune system, its pharmacological replacement in GHD patients seems to positively influence their inflammatory status. In addition, the impaired fibrinolysis associated with GHD may represent a further link between GH–insulin‐like growth factor 1 axis impairment and COVID‐19 severity, as it has been associated with both conditions. In conclusion, several sources of evidence have supported a relationship between GHD and COVID‐19, and they also shed light upon potential beneficial effects of recombinant GH treatment on COVID‐19 patients.
