Popis: Objectives The triggers of relapsing polychondritis (RPC) are not fully characterized. This study was performed to explore the association between mechanical injuries and RPC.Methods The history of mechanical injuries of 127 RPC patients was reviewed and confirmed. The characteristics and survivals of patients with mechanical injuries were analyzed. Results Fifty-four patients (42.5%) had 63 mechanical injuries, among which 17 were cartilage-related. Thirty mechanical injuries in 28 patients occurred in the preceding one year before disease onset. Patients with mechanical injuries(n=54) had a higher proportion of female gender (59.3% vs 38.4%, P=0.002) and similar features compared to those without injuries(n=73), regarding clinical manifestations and mortality rate. Among 54 patients with mechanical injuries, patients with cartilage related injury(n=17) had a significantly higher rate of tracheobronchial chondritis (64.7% vs 27%, P= 0.008), a significantly lower rate of auricular chondritis (35.3% vs 67.6%, P=0.026) and a relatively higher mortality rate(29.4% vs 8.1%, P=0.041) compared with those with non-cartilage related injury(n=37).Conclusion Our findings suggest that both cartilage-related and non-cartilage related injury may be triggers of RPC and patients with cartilage related injury seem to be more severe than those without.
