Abstract

In this study, we aimed to measure the melatonin levels in COVID-19 positive patients and to investigate the relationship of these levels with depression, death anxiety and insomnia. COVID-19 positive pneumonia group, COVID-19 negative pneumonia group and healthy control groups were included in the study. Melatonin ELISA kit was used. Blood samples were taken at 23:00 h (h), 02:00 h and 06:00 h. Beck Depression Inventory (BDI), Templer Death Anxiety Scale (TDAS), Insomnia Severity Index (ISI) were employed to collect data from the participants. The melatonin levels of COVID-19 positive patients at 23:00 h were lower than the control group. In addition, and the melatonin levels of COVID-19 positive patients at 02:00 h and at 06:00 h were lower than both the COVID-19 negative patient group and the control group. It was observed that the peak melatonin concentration of COVID-19 positive patients occurred at 06:00 h. BDI, TDAS and ISI scores of COVID-19 positive patients were higher than other groups. There was a negative correlation between BDI, TDAS, ISI scores of COVID-19 positive patients and their melatonin levels. The correlation between all scale scores and melatonin levels was higher at 02:00 h. Adding melatonin to the treatment of COVID-19 positive patients may be beneficial for these patients experiencing high levels of depression, anxiety and insomnia.
