An unusual case report of COVID-19 presenting with syndrome of inappropriate ADH secretion

Coronavirus disease-2019 (COVID-19) caused by novel coronavirus continues to produce enormous health effects and deaths since it started in 2019. Research till now has shown that COVID-19 manifests with unusual presentations causing various challenges in its management. Hyponatremia is a common condition found in critical care units and syndrome of inappropriate ADH (SIADH) accounts for one-third of those cases. Several infections associated with COVID-19 have been reported, but there are only few case reports of association with SIADH. We report the case of a 30-year-old male admitted with seizure due to acute symptomatic hyponatremia and SIADH attributed to COVID-19.
