Serum progranulin levels in dermatomyositis patients with interstitial lung disease were associated with prognosis. The cumulative survival rate for 6 months in the serum progranulin (PGRN) <200 ng/ml group and the ≥200 ng/ml group of patients with dermatomyositis with interstitial lung disease are shown. The cumulative survival rate was calculated using the Kaplan-Meier test. The log-rank test was also used to compare survival. The cumulative survival rate was significantly lower in the group with serum PGRN levels ≥200 ng/ml than in the group with serum PGRN levels <200 ng/ml.
