title: Serum IL8 and mRNA level of CD11b in circulating neutrophils are increased in clinically amyopathic dermatomyositis with active interstitial lung disease.
abstract: The objective of this study is to assess serum IL8 and the potential activity of circulating neutrophils on relative messenger RNA (mRNA) levels and their relationship with disease activity in clinically amyopathic dermatomyositis (CADM) associated with interstitial lung disease (ILD). We studied 18 CADM patients and compared them with 18 classic dermatomyositis (DM) patients and 18 healthy control subjects. Serum IL8 level and mRNA expressions of neutrophils (chemokine (C-X-C motif) receptor 1 (CXCR1), cluster of differentiation molecule 11b (CD11b), cluster of differentiation 64 (CD64), myeloid cell leukemia 1 (MCL1), interleukin-18 (IL18)) were detected. The overproduction of serum IL8 level was most significant in the CADM group with active period. The mRNA expressions of CD11b, IL18, and MCL1 were greatly increased in the neutrophils in patients with CADM compared with DM or healthy controls. Up-expressions of CD11b, IL18, and MCL1 were detected in the neutrophils in CADM patients of active period compared with remission period. A positive correlation was found between CD11b mRNA level and high-resolution computed tomography (HRCT) score, in CADM associated with ILD. Serum IL8 level and mRNA levels of CD11b, MCL1, and IL18 in circulating neutrophils are related with the disease activity of CADM-ILD. The mRNA level of CD11b is positively correlated with HRCT score in CADM-ILD.
