Patients with idiopathic inflammatory myopathy had an increased risk for mortality, according to a recently published study that used data from Sweden.
“In this first nationwide, population-based [idiopathic inflammatory myopathy] IIM mortality study, we have demonstrated that IIM indeed is associated with increased mortality,” the researchers wrote. “There has been some discussion regarding whether there is an increased mortality in patients diagnosed with IIM in recent years, but this study leaves little doubt to this question. This study also demonstrates that the mortality is highest within the first year of IIM diagnosis, and it remains more than doubled compared with the general population throughout a follow-up of over 10 years, although the increased relative risk was not statistically significant after 10 years.”
