Case Reports: Exposure to SARS-CoV-2, Acute Kidney Injury, and Lithium Toxicity.

ABSTRACT

PURPOSES: The aims of the study were to review 3 cases of lithium toxicity among individuals with bipolar disorder who were diagnosed with COVID-19 and to review the literature discussing the implications of COVID-19 and exposure to SARS-CoV-2 relative to medical use of lithium in management of bipolar disorder. METHODS: This is a case review of medical and psychiatric notes of 3 individuals with bipolar disorder, managed with lithium, who developed COVID-19. This study discussed these cases in context of previous case reports and relevant literature pertaining to lithium and exposure to SARS-CoV-2. FINDINGS: Infection with SARS-CoV-2 along with symptoms of COVID-19 and mental state changes in three individuals were temporally associated with lithium levels in the toxic range. IMPLICATIONS Exposure to SARS-CoV-2 or symptoms suggestive of COVID-19 should result in increased clinical monitoring of individuals taking lithium. Those taking lithium and providers are advised to have a low clinical threshold for requesting lithium levels and kidney function estimates for the duration of the COVD-19 pandemic.
