Relapsing polychondritis - analysis of symptoms and criteria.

Abstract

ObjectivesRelapsing polychondritis (RP) is a rare disease characterised by recurrent inflammation of the cartilaginous structures and proteoglycan-rich organs. The aim of this case series study is to share the 10-year clinical experience of our department in diagnosing RP patients in the context of data from available published studies.Material and methodsA retrospective case analysis of 10 patients with symptoms of RP, hospitalised at the Department of Rheumatology and Internal Diseases of Wrocław University Hospital between January 2008 and December 2018.ResultsNine out of 10 patients fulfilled at least one of the three sets of the diagnostic criteria. The mean age (±standard deviation) at diagnosis was 54.4 ±13.3 years and ranged from 32 to 73 years. The symptoms suggestive of the RP diagnosis were mainly inflammation of the pinna (in 80% of patients) and laryngeal stenosis (in 20% of patients). The mean age at which initial symptoms were observed was 52.3 ±12.0 years and ranged from 31 to 69 years. Auricular chondritis was the first manifestation of the disease in 40% of cases (two women and two men) laryngeal chondritis in 20%, nasal chondritis in 10%, and bronchial stenosis in 10%. Other initial symptoms were polyarthritis, which was present in 10% of cases (male) and general symptoms observed in 10%.ConclusionsA thorough analysis of the entire medical history with specific questions about the occurrence of the manifestations of the disease in the past leads to the diagnosis of RP. The RP also should be considered in differential diagnosis of respiratory track narrowings. It is very useful to apply the three sets of criteria simultaneously in the diagnostic process.
