Abstract

Treatment for coronavirus disease 2019 (COVID19) pneumonia remains empirical and the search for therapies that can improve outcomes continues. Melatonin has been shown to have anti-inflammatory, antioxidant, and immune-modulating effects that may address key pathophysiologic mechanisms in the development and progression of acute respiratory distress syndrome (ARDS), which has been implicated as the likely cause of death in COVID19. We aimed to describe the observable clinical outcomes and tolerability of high-dose melatonin (hdM) given as adjuvant therapy in patients admitted with COVID19 pneumonia. We conducted a retrospective descriptive case series of patients who: 1) were admitted to the Manila Doctors Hospital in Manila, Philippines, between March 5, 2020 and April 4, 2020; 2) presented with history of typical symptoms (fever, cough, sore throat, loss of smell and/or taste, myalgia, fatigue); 3) had admitting impression of atypical pneumonia; 4) had history and chest imaging findings highly suggestive of COVID19 pneumonia, and, 5) were given hdM as adjuvant therapy, in addition to standard and/or empirical therapy. One patient admitted to another hospital, who one of the authors helped co-manage, was included. He was the lone patient given hdM in that hospital during the treatment period. Main outcomes described were: time to clinical improvement, duration of hospital stay from hdM initiation, need for mechanical ventilation (MV) prior to cardiopulmonary resuscitation,…

How strong is the evidence?

Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 10 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
