BACKGROUND: The objective of this study was to detect the level of olfactory function in patients with systemic lupus erythematosus (SLE) and to explore the relationship between impaired olfactory function and anti-ribosomal P protein antibody (ARPA), disease duration, and age.
MATERIAL AND METHODS: The level of olfactory function in 65 patients with SLE and 50 healthy participants was detected using the Connecticut Chemosensory Clinical Research Center (CCCRC) method; serum ARPA levels in SLE patients and the healthy control group were detected by enzyme-linked immunosorbent assay (ELISA).
RESULTS: CCCRC scores in the active SLE group was lower than that in the inactive SLE and healthy control groups (P<0.01). In SLE patients, the CCCRC scores of ARPA-positive patients were lower than those of ARPA-negative patients (P<0.01). A negative correlation was discovered between CCCRC scores and ARPA serum levels in SLE patients. Multiple linear regression analyses showed a correlation among the CCCRC score, age, and ARPA.
CONCLUSIONS: Olfactory dysfunction was found in patients with active SLE; which correlated with SLE disease activity and ARPA levels.
