Sinonasal Symptoms Show Potential in Predicting GPA Vasculitis Relapse

Patients with granulomatosis with polyangiitis (GPA) who scored high on a sinonasal symptom test are nearly three times as likely to relapse, according to a new study.

These patients reported higher scores months and up to 2 years before a disease flare, despite having low disease activity otherwise.

The study uses a different approach to try to predict relapse, compared with measuring biomarkers in lab tests, said Zachary Wallace, MD, a rheumatologist at Massachusetts General Hospital in Boston, Massachusetts. He was not involved with the study.

“It’s exciting because it might suggest that we could use something as simple as a survey to stratify someone’s risk of relapse,” he told this news organization.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a rare disease, with an estimated prevalence of 200-400 cases per million people. It is also heterogeneous, which makes it difficult to predict the risk for relapse for a given patient.

“Investigators have long searched for a reliable prognostic marker that identifies patients at high vs low risk of relapse in AAV but, except for ANCA type, no prognostic biomarker is routinely used to inform treatment decision-making,” wrote lead author Ellen Romich, MD, a rheumatology fellow at the University of Pennsylvania in Philadelphia, Pennsylvania, and colleagues.

Proteinase 3-ANCA (compared with myeloperoxidase-ANCA) has been tied to a higher risk for relapse, as well as gastrointestinal complications, sinonasal disease, and patient global assessment scores. In this new study, Dr. Romich and colleagues evaluated if patient-reported outcomes of sinonasal disease could predict AAV disease activity and relapse.

Researchers used data from a prospective, longitudinal cohort study through the University of Pennsylvania Vasculitis Center from 2016 to 2022. They included 107 patients with GPA, 40 patients with eosinophilic granulomatosis with polyangiitis (EGPA), 21 patients with microscopic polyangiitis (MPA), and 51 healthy controls.

Patients completed a median of four clinic visits during the duration of the study.

During each visit, patients filled out the 22-item SinoNasal Outcome Test (SNOT-22), a validated questionnaire that assesses rhinosinusitis. The tool asks patients to rate a list of symptoms from 0 to 5 in five categories: Rhinologic, extra-nasal, ear and face, psychologic, and sleep. The possible total score ranges from 0 to 110.

Disease activity was measured via the Birmingham Vasculitis Activity Score for Wegener’s Granulomatosis. The results were published online in Arthritis Care & Research.

Patients were, on average, 55 years old with an AAV duration of 3 years. (The mean age of healthy participants was 59.) More than half (58%) of patients were female, and 95% were White. The majority had a history of a flare (54%), and 60% of those flares had sinonasal involvement.

Even in remission, patients with AAV generally had on average higher SNOT-22 scores than healthy comparators (20 vs 5). Higher disease activity also correlated with higher SNOT-22 scores.

In patients with GPA, a high SNOT-22 score (total score of 41 or above) was associated with an increased risk for relapse within 2 years (hazard ratio, 2.7; P = .02). This association was not found for EGPA or MPA. This higher risk remained in a sensitivity analysis that included only patients with no history of sinonasal disease.

“Interestingly, among patients with GPA, SNOT-22 scores are elevated months to years prior to onset of systemic relapse but remain low in patients in sustained remission,” the authors wrote.

While other patient-reported outcomes have been validated for AAV, SNOT-22 may provide more detail on upper airway disease, commented Paul Monach, MD, PhD, an adjunct associate professor of medicine at the Boston University Chobanian & Avedisian School of Medicine and a rheumatologist at the VA Boston Healthcare System, Boston, Massachusetts.

“Upper airway GPA has not been studied as much as systemic GPA and MPA,” he told this news organization. “There are very few clinical trials, and we need better outcome measures like this.”

Dr. Romich noted that this work is still in the “early stages,” and SNOT-22 will need to be further studied and validated in other patient cohorts before its inclusion in clinical practice.

“There’s certainly more work that needs to be done to understand how the SNOT-22 questionnaire works in this patient population,” she said, including its predictive value compared with other known risk factors for relapse. “But I think it’s something that’s promising that we could use as a patient-reported outcome to try to, visit-to-visit, track their sinonasal symptoms.”

This study was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases and an NIH Rheumatology Research Training Grant. Dr. Romich, Dr. Wallace, and Monach reported no other relevant disclosures.
