CBT and rehabilitation likely to improve long covid symptoms
· News-MedicalIntermittent aerobic exercise also probably improves physical function compared with continuous aerobic exercise. But the researchers found no compelling evidence to support the effectiveness of other interventions, including certain drugs, dietary supplements, inspiratory muscle training, transcranial direct current stimulation, hyperbaric oxygen therapy, or mobile education apps.
Although most patients recover from covid-19, up to 15% (an estimated 65 million people globally) might experience long term health effects, including fatigue, muscle pain (myalgia), and impaired cognitive function.
Healthcare providers are increasingly seeing patients with long covid and, in the absence of trustworthy and up-to-date summaries of the evidence, patients may receive unproven, costly, and ineffective or harmful treatments.
To address this, researchers trawled databases for trials randomising adults with long covid to drug or non-drug interventions, placebo or sham, or usual care.
They found 24 relevant trials involving 3,695 patients investigating drugs, physical activity or rehabilitation, behavioural interventions, dietary interventions, medical devices and technologies, and combinations of physical exercise and mental health rehabilitation.
The trials were of varying quality, but the researchers were able to assess their risk of bias and the certainty of evidence using established tools.
Moderate certainty evidence suggested that, compared with usual care, an online programme of CBT probably reduces fatigue and improves concentration, and an online, supervised combined physical and mental health rehabilitation programme probably increases the proportion of patients that experience meaningful improvement or recovery, reduces symptoms of depression and improves quality of life.
However, no compelling evidence was found to support the effectiveness of other interventions, including the antidepressant vortioxetine, the antibody leronlimab, a combination of probiotics and prebiotics, the antioxidant coenzyme Q10, brain retraining, transcranial direct current stimulation, inspiratory muscle training, hyperbaric oxygen, and a mobile education app on long covid.
These results will be updated as new evidence becomes available, they add.
