A Third of Long Haulers Have ‘FibroCOVID’

Nearly a third of patients with long-haul covid have symptoms strikingly similar to fibromyalgia, according to a new study by Italian researchers who say being male and obese are strong risk factors for developing “FibroCOVID.”
“In the light of the overwhelming numbers of the SARS-CoV-2 pandemic, it is reasonable to forecast that rheumatologists will face up with a sharp rise of cases of a new entity that we defined (as) ‘FibroCOVID’ to underline potential peculiarities and differences,” wrote lead author Francesco Ursini, MD, an Associate Professor of Rheumatology at the University of Bologna.
The study findings, published online in RMD Open: Rheumatic & Musculoskeletal Diseases, are based on a survey of over 600 patients with post-acute COVID-19 – also known as "long COVID."
Nearly 31% of the long-haulers had musculoskeletal pain, fatigue, cognitive impairment and sleep disturbances – classic symptoms of fibromyalgia, as defined by the American College of Rheumatology.
Unlike traditional fibromyalgia, which primarily affects women, a higher percentage of men (43%) had symptoms of FibroCOVID. They were also more likely to be obese, have high blood pressure, and a severe COVID-19 infection.
“Globally, respondents with FM (fibromyalgia) exhibited features suggestive of a more serious form of COVID-19, including a higher rate of hospitalisation and more frequent treatment with supplemental oxygen,” Ursini and his colleagues reported. “Taken together, our data suggest a speculative mechanism in which obesity and male gender synergistically affect the severity of COVID-19 that, in turn, may rebound on the risk of developing post-COVID-19 FM syndrome and determine its severity.”
The long-term effects of a COVID-19 infection are currently unknown. While some patients have minor symptoms and recover quickly, about a third will develop long COVID and have symptoms that persist for several months after the initial infection.
Previous studies of long-haul covid have also found similarities with autoimmune conditions such as lupus and myalgic encephalomyelitis, also known as chronic fatigue syndrome (ME/CFS).
Vaccines Cut Risk of Long Covid
Being fully vaccinated against COVID-19 cuts the risk of developing long covid in half, according to a new UK study. Researchers at King’s College London looked at health data from a mobile app used by millions of people in the UK and found that those who received two doses of the Moderna, Pfizer or AstraZeneca vaccines had significantly lower risk of a “breakthrough” infection that turns into long covid.
“We found that the odds of having symptoms for 28 days or more after post-vaccination infection were approximately halved by having two vaccine doses. This result suggests that the risk of long COVID is reduced in individuals who have received double vaccination, when additionally considering the already documented reduced risk of infection overall,” researchers reported in the journal The Lancet Infectious Diseases.
“Almost all individual symptoms of COVID-19 were less common in vaccinated versus unvaccinated participants, and more people in the vaccinated than in the unvaccinated groups were completely asymptomatic.”
Fully vaccinated.people aged 60 or older were more likely to have no symptoms of a breakthrough infection, according to researchers.
