 The study aimed to investigate salivary and lacrimal symptoms in Norwegian cohort of APSI patients, N equals 41, and found mild salivary and or lacrimal gland dysfunction manifesting in low saliva or tear flow in a total of 62 percent of APSI patients. The study also identified several putative autoantigens in one patient, although none of these were verified as APSI specific. Additionally, the study found that APSI patients have an altered antimicrobial signature in both sera and saliva, which requires further investigations. This article was authored by Bergethe E.
