Abstract
PAULIN, Francisco et al. Prognostic value of IL13 plasmatic levels in patients with rheumatoid arthritis and interstitial lung disease: a prospective cohort study. Rev. argent. reumatolg. [online]. 2022, vol.33, n.4, pp.215-222. ISSN 0327-4411. http://dx.doi.org/10.47196/rar.v33i4.700.
Introduction:
the aim of our study was to analyze the relationship between the concentrations of IL13 in serum and the prognosis of interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients.
Materials and methods:
we conducted a prospective cohort study. We measured IL13 levels in serum. Patients were divided in two groups using the median of IL13 value as cut off point. Time to a decline of 5% or more in FVC% from basal measurement was estimated using Kaplan Meier method. Univariate and multivariate Cox models were applied.
Results:
we included 47 patients. The mean (SD) time of follow-up was 12.7 (12.5) months. The Kaplan Meier estimator at 15 months was 0.48 (CI 95% 0.13-0.76) in the group with higher values of IL13, and 0.86 (CI95% 0.54-0.93) in the other group (p=0.037). In the Cox multivariate analysis, the values of IL13 were significantly associated with a decline of 5% or more in FVC% in the follow-up (HR 17.64 (CI 95% 1.89-164.1) p=0.012).
Conclusions:
our results indicate that patients with higher values of IL13 in serum presented higher decline in FVC% during their follow-up.
