Abstract:
Objective:To analyze the clinical features, risk factors and prognosis of IPA combined with lung infection, aiming to further improve clinicians' understanding and diagnosis and treatment of it.Methods:Patients with IPA admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2013 to October 2021 were retrospectively enrolled, and their clinical data was collected from the electronic medical record, including demographic information, clinical characteristics, biochemical indicators, auxiliary examination, microbial data and prognostic indicators. Patients were divided into two groups of IPA with pulmonary infection and IPA alone, and the clinical features, risk factors and prognosis of IPA patients with pulmonary infection were compared and analyzed in comparison with IPA patients alone.Results:A total of 156 IPA patients were finally recruited, with an average age of (67.12±12.89) years old and a main male proportion of 69.20%. Among them, there were 86 cases (55.13%) with IPA with pulmonary infection and 70 cases (44.87%) with IPA alone. Half of the IPA patients with pulmonary infection were mixed with one pathogen. The main pathogen of mixed infection was bacteria (82.72%), whereas acinetobacter baumannii accounted for the most common pathogen(25.93%, 42/162). Multivariate logistic regression analysis found that mechanical ventilation ( OR 4.89, 95% CI 2.23-10.70) and prior neutropenia ( OR 6.41, 95% CI 1.33-30.93) were independent risk factors for the occurrence of IPA with pulmonary infection. Compared with IPA alone, IPA patients with pulmonary infection were more likely to develop septic shock(69.80% vs. 32.90%, P <0.05), and have longer lengthes of hospital stay [16.00(8.00,36.50) vs.13.50 (7.00,20.50)] and ICU stay[11.50(6.00,31.25) vs.8.50(1.75,11.00)], and mechanical ventilation days [12.00(6.75, 25.25) vs.8.00(2.00,10.00)], as well as a higher 28-day mortality (55.80% vs.35.70%) and in-hospital mortality (64.00% vs. 35.70%). Conclusions:IPA patients with pulmonary infection accounts for more than half of IPA patients. The main respiratory etiology of IPA with pulmonary infection is acinetobacter baumannii. The independent risk factors of IPA patients with pulmonary infection are mechanical ventilation and neutropenia. The prognosis of IPA patients with pulmonary infection is worse than patients with IPA alone, which is worthy for the attention of physicians.
