Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a life-threating viral infection that is highly transmissible and be lethal. Although many patients with mild symptoms recover, an acute form of the infection is characterized by rapidly evolving respiratory failure, an acute inflammatory response, organ failure, and death. Herein, we describe the use of clonidine to modulate the acute inflammatory consequences of this infection in three cases. The patients were three men between 40-50 years from Kathmandu valley, during the peak of COVID-19 (September 2020- January 2021). All three patients presented with typical COVID-19 symptoms (daily fever, loss of smell and taste, excessive fatigue, cough) and had pneumonia with typical finding in CT Scan of chest. Patient 1was able to maintain adequate oxygenation despite having pneumonia, managed at home by regular self-monitoring of vitals and treatment with oral clonidine whereas patient 2 and 3 developed significant pneumonia and had difficult in maintaining oxygenation hence admitted in hospital and treated with clonidine and supplemental oxygen. All three patients recovered completely. In this limited report, we proposed several mechanisms by which clonidine may be useful in managing rapidly evolving SARS-CoV-2 infection based on the rationale that early clonidine administration can intervene in the catecholaminergic response that characterizes rapid clinical deterioration including presumptive cytokine storm that occurs in COVID-19 infection in vulnerable populations.
