TOPLINE:
Age older than 65 years and serum creatinine greater than 140 micromol/L at the time of systemic polyarteritis nodosa (PAN) diagnosis were significant predictors of mortality.
METHODOLOGY:
- A total of 358 patients diagnosed with PAN between 1990 and 2020 were identified from retrospective chart reviews and prospective cohorts from nine countries as a part of GLOBAL-PAN, a collaboration of the European Vasculitis Society, the Vasculitis Clinical Research Consortium, and other networks.
- The goal of the retrospective chart review was to characterize the nature, presentation, and survival rates of patients with PAN.
- The study population included 174 female and 184 male patients; 282 had systemic PAN (sPAN) and 76 had cutaneous PAN (cPAN); the mean age at diagnosis was 44.3 years.
TAKEAWAY:
- Overall survival rates at 1, 5, and 10 years for patients with sPAN were 97.1%, 94.0%, and 89.0%, respectively.
- Significant independent predictors of mortality were age ≥ 65 years at the time of sPAN diagnosis (hazard ratio [HR], 3.85), serum creatinine > 140 micromol/L at the time of diagnosis (HR, 4.93), gastrointestinal involvement (HR, 3.51), and central nervous system involvement (HR, 3.56).
- Constitutional symptoms were significantly more common in patients with sPAN vs cPAN (78.8% vs 44.7%), while patients with cPAN were significantly more likely to be female and have more skin nodules than patients with sPAN.
- Relapse over a median disease duration of 59.6 months was slightly higher for cPAN vs sPAN (38.8% vs 32.1%).
IN PRACTICE:
“This study helps better define the demographic and clinical characteristics of patients with PAN and differentiates sPAN from cPAN,” the researchers wrote.
SOURCE:
The lead author of the study was Omer Karadag, MD, of Hacettepe University, Ankara, Turkey. The study was published online on February 12 in Arthritis & Rheumatology.
LIMITATIONS:
Study limitations included the combination of prospective and retrospective data, varying approaches to patient assessment, and lack of data on treatment effects.
DISCLOSURES:
The study was supported by the Vasculitis Clinical Research Consortium, which received funding from the National Center for Advancing Translational Science, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, and the National Center for Research Resources. Dr. Karadag disclosed research grants from AbbVie, Novartis, Viela-Bio, and TR-Pharma, and consulting fees from AbbVie, Abdi Ibrahim, Celltrion, Novartis, Pfizer, Sandoz, and UCB.
