LIVERPOOL, ENGLAND – Cardiovascular disease was the predominant cause of death of patients with granulomatosis with polyangiitis 1-5 years after a diagnosis in a study by U.K. researchers, suggesting that this could be a target for future intervention.
While active disease was the No. 1 cause of death within the first year of diagnosis in 40% of patients with granulomatosis with polyangiitis (GPA), it was overtaken by cardiovascular disease (CVD) as the main cause of death in 37.5% of patients in the next 4 years from diagnosis.
“The idea for this study came from patients with vasculitis who were polled by Vasculitis UK,” Fiona A. Pearce, MBBS, explained at the British Society for Rheumatology annual conference.
“Further research into mortality was one of their top priorities as patients want to know the honest truth about what is going to happen to them,” added Dr. Pearce, of the division of epidemiology and public health at the University of Nottingham (England).
GPA is a rare type of vasculitis that is estimated to occur in around 1,350 people every year in the United Kingdom. Mortality is known to be high, with around 11%-14% of patients dying in the first year of diagnosis, but there are few data on what happens over a longer term.
The aim of the study was therefore to examine patient survival in the long term – what were the mortality rates several years post diagnosis? Did the risk of death remain high throughout this time and did the causes of death change?
