Abstract:
ObjectiveTo investigate the clinical features and risk factors of patient with Wegener's granulomatosis complicated with pulmonary infection.Methods Patients with Wegener's granulomatosis admitted to our hospital in the past 11 years were retrospectively analyzed.Comparisons between groups were performed by t tests or Fisher test.ResultsPulmonary infection occurred in 27 cases with an incidence rate of 29％.Twenty-six percent of pulmonary infections occurred at the initial diagnosis,and 44％ occurred within 6 months,while 30％ occurred later than 6 months.The clinical manifestations of pulmonary infection were productive cough (89％),hemoptysis (63％),fever and fatigue (56％),chest pain and pactoralgia (33％).The most common causative pathogen were bacteria(59％ ),fungi(37％ ),and tubercle bacillus(37％ ).Sinus infection(P=0.01),hypoproteinemia(P=0.03),hypoimmunoglobulinemia (P=0.007),and methylprednisolone pulse therapy(P=0.002) were the risk factors for pulmonary infection.ConclusionThe occurrence of Wegener's granulomatosis complicated with pulmonary infection is high within 6 months.The most common clinical manifestation is productive cough.The most common causative pathogens are bacteria,tubercle bacillus and fungi.Sinus infection,hypoproteinemia,hypoimmunoglobulinemia,and methylprednisolone pulse therapy are risk factors of pulmonary infection.
