ACTA ENDOCRINOLOGICA (BUC)

At the end of 2019, a novel coronavirus was identified as the cause of a cluster of pneumonia in China and it spread quickly to other countries. Although Covid-19 causes severe pneumonia, it is known that it can be associated with different diseases and prognosis of disease can be due to many of disorders such as hyponatremia. A 65-year-old female patient with sarcoidosis, cronic obstructive lung disease, hypertension and congestive heart failure presented to the emergency department with shortness of breath and fever. Oropharyngeal swab for Covid-19 PCR test was positive. After the initiation of treatment, the patient developed hyponatremia. This case is remarkable because there is no reported case of Covid-19 and inappropriate ADH syndrome coexistence and it demonstrates that there may be a correlation between Covid-19 infection prognosis and hyponatremia.
