[Determination of serum type III procollagen in patients with rheumatoid arthritis and interstitial lung disease].
Type III serum procollagen (Pc III) was measured by radio-immunossay in 30 rheumatoid arthritis(RA) patients with or without intestitial lung disease(ILD) and in 15 normal control subjects. The results showed that Pc III of RA patients were significantly higher than that of normal controls. Pc III levels is higher in RA patients with ILD than that in RA patients without ILD. The results suggested that RA patients with higher serum Pc III is more vulnerable to ILD, and the determination of Pc III might be valuable to show the complicated ILD.
