Though extra sufferers with inflammatory rheumatic ailments (iRD) report signs resembling lengthy COVID, the info recommend that many of those signs may be attributed to the underlying rheumatic illness. “Total, we discover the info fairly reassuring,” stated Boekel, Amsterdam Rheumatology and Immunology Heart, Amsterdam College Medical Heart, the Netherlands.
The outcomes had been additionally revealed Might 31 in Lancet Rheumatology.
The chance of growing lengthy COVID after an infection with the Omicron variant seemed to be larger in sufferers with iRD, with 21% assembly the standards set by the World Well being Group (WHO), in contrast with 13% of wholesome people (odds ratio [OR], 1.58; P = .037). Fatigue and lack of health had been the commonest lengthy COVID signs reported by each iRD sufferers and controls. Nonetheless, the distinction in threat decreased after accounting for elements which can be considerably related to an elevated threat for lengthy COVID, similar to physique mass index and the severity of the acute COVID-19 an infection (adjusted OR, 1.46; P = .081). The length of signs didn’t present a statistically important distinction.

Kim Lauper, MD, College of Geneva, Switzerland, who chaired the session wherein Boekel reported the research, stated to Medscape Medical Information that the info needs to be interpreted with warning. “The info show that rheumatic illness itself isn’t a threat issue for lengthy COVID. Nonetheless, sufferers with rheumatic ailments are at a better threat of extreme illness, which in flip will increase the chance of lengthy COVID. Due to this fact, as a inhabitants, these sufferers are extra prone to lengthy COVID general,” she stated.
Furthermore, no matter their earlier COVID-19 an infection standing, iRD sufferers usually exhibit signs just like these of lengthy COVID even with no prior COVID-19 an infection. (There was no historical past of COVID-19 in 21% of iRD sufferers vs 11% of controls.) This means that a number of the reported lengthy COVID signs may very well be medical manifestations of the underlying rheumatic illness, thereby complicating the prognosis of lengthy COVID on this inhabitants. The research employed the WHO definition of lengthy COVID, which incorporates persistent signs lasting at the least 8 weeks, starting inside 3 months of a confirmed SARS-CoV-2 an infection, and that can’t be attributed to another prognosis. Nonetheless, the info introduced in Milan point out that the WHO definition “isn’t well-suited for sufferers with iRD as a result of important overlap in signs and options,” Boekel concluded.
The instances of Omicron COVID-19 had been recognized throughout January 1-April 25, 2022, amongst iRD sufferers recruited from the Amsterdam Rheumatology and Immunology Heart. The inhabitants with confirmed SARS-CoV-2 Omicron an infection throughout this era was monitored for lengthy COVID. The full variety of sufferers included within the research consisted of 77 iRD sufferers and 23 wholesome controls. When requested in regards to the potential threat of choice bias within the survey, Boekel said that solely roughly 8% of members declined to reply, and the nonresponders had been akin to the respondents. She concluded that “the chance of choice bias is minimal.”
In an editorial revealed in Lancet Rheumatology , Leonard H. Calabrese, Cleveland Clinic, Ohio, supplied his insights on the findings. He emphasised that, “at current, lengthy COVID stays an necessary actuality that considerably impacts the lives of hundreds of thousands of people, but it stays incompletely outlined […]. These limitations in defining instances mustn’t in any approach undermine the experiences of these affected by lengthy COVID. As an alternative, they need to function a reminder that, at this stage of the pandemic, we sadly nonetheless lack validated classification standards for lengthy COVID. It’s essential to incorporate non-SARS-CoV-2 contaminated controls in all research to additional improve our understanding.”
