Clinical analysis of dermatomyositis/polymyositis complicated with lung disease
Objective:To analyze the species and clinical features of dermatomyositis(DM) and polymyositis(PM) complicated with lung diseases. Methods:Totally 54 cases of hospitalized DM/PM patients with pulmonary disease
who are admitted to the First Affiliated Hospital of Chongqing Medical University from January 2011 to November 2014 were taken as the objects. The general condition
clinical manifestation
laboratory examination
pulmonary function
imaging
treatment and prognosis were retrospectively analyzed.Results:DM/PM complicated with interstitial lung disease(ILD) occurs most frequently
whose common symptoms are cough
shortness of breath
elevated erythrocyte sedimentation rate(ESR)
C-reactive protein(CRP)
creatine kinase(CK) and ferritin as well as positive anti-Jo-1 antibody;the abnormal lung function mainly displays as diffused and restrictive ventilatory dysfunction;ground glass is the most common sign in thoracic CT. Cutaneous vasculitis and malignant erythema are obvious in DM/PM complicated with lung cancer;80% patients has abnormally elevated CK and negative anti-Jo-1 antibody. DM/PM complicated with pneumomediastinum is a rare but serious complication;66.7% patients have significant skin vasculitis. All patients are young men
who have lower CK
increased ESR
negative anti-Jo-1 antibody. Conclusion :DM/PM patients complicated with lung disease are associated with corresponding inflammatory and immunological indexes.
