Аннотация
OBJECTIVE: Patients with idiopathic pulmonary fibrosis (IPF) commonly present with sicca symptoms. This study aimed to assess labial minor salivary glands (LMSGs) in those patients to rule out Sjögren's syndrome (SS), in which sicca symptoms are the clinical hallmark.
STUDY DESIGN: Cases of patients with IPF with sicca symptoms referred to the oral medicine clinic at the University of Florida within the last 13 years were selected with institutional review board approval. Demographic characteristics, clinical findings, laboratory results, and histomorphologic parameters were retrospectively analyzed.
RESULTS: A total of 12 patients (9 men and 3 women, ages 55-76 years) were identified. History of exposure to asbestos or chemicals, smoking, and medication information was obtained. All patients reported sicca symptoms with 57% of those exhibiting objective or borderline dryness. Anti-SSA/Ro and anti-SSB/La were positive in 25% and 8% of the cases, respectively. Microscopically, 1 out of 12 patients was biopsy positive in the absence of anti-SSA/Ro, fulfilling the 2016 SS criteria with positive sialometry.
CONCLUSIONS: A LMSG biopsy is critical to identify SS in patients with diagnosed IPF and present sicca symptoms, especially those with negative serology, as revealed in our study.
