Abstract

IRB approval date 14-APR-2024 and public at https://plataformabrasil.saude.gov.br/login.jsf since IURB approval

Long COVID is a multi-systemic condition comprising often severe and persistent symptoms (longer than 12 weeks) that follow a known episode of COVID-19 and cannot be explained by another medical condition. This condition is observed in up to 15% of all individuals after an acute episode of COVID-19, even in those who had a mild and oligosymptomatic SARS-CoV-2 infection. Around 40% of these patients present symptoms that significantly compromise their daily activities.

There is increasing evidence that LONG COVID is accompanied by dysregulated, persistent and uncontrolled inflammation, often accompanied by the development of an autoreactive immune response, including autoantibodies. Symptoms can last months or years, particularly in cases of chronic fatigue syndrome, with significant proportions of individuals having significant chronic impairment, preventing the performance of work and social activities.

Conditions: Long COVID-19 Syndrome, Chronic Fatigue Syndrome.

Primary outcome: Improvement on Fatigue Severity Score Scale (FSS).

Enrollment: 399 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 399 participants or records.
