Clinical analysis of 56 cases with secondary fungal infection with chronic obstructive pulmonary disease

Abstract

Objective To figure out clinical characteristics and risk factors of secondary fungal infection in patients with chronic obstructive pulmonary disease(COPD).Methods Two hundred and ninetysix patients with COPD were enrolled in our study who were treated in the People's Hospital of Liaocheng.Of whom,56 cases with secondary fungal infection were served as infection group and other 240 cases were non infection group.The clinical data including sorts of antibiotics,the therapy periods of antibiotic,hormones,hypoalbuminemia,invasive operation and death cases were recorded.Sort of fungal were determined by sputum culture.Results Mortality of infection group was 16.1％ (9/56),obviously higher than that of the noninfected group (6.2％ (15/240)) and the difference was significant(x2 =6.436,P ＜0.05).The average sorts of antibiotic,the therapy periods of antibiotic,rate of hormones,the rate of hypoalbuminemia,rate of were invasive operation in infection group were (2.6 ±0.8),(15.4 ±2.6) d,41.1％ (23/56),57.5％ (32/56),35.7％ (20/56),higher than those in non infection group(1.6 ±0.6,(9.6 ±2.2) d,8.3％ (20/240),12.1％ (29/240),5.4％ (13/240) ; P ＜ 0.05).The total efficacy rate in non infection group was 90.4％ (217/240),higher than that in infection group (78.6％ (44/56)),and the difference was significant (x2 =4.248,P ＜ 0.05).The majority sort of fungal in infection group was monilia albicans.Conclusion The main risk factors of secondary fungal infection in patients with COPD include long-term using high-end application antibiotics,hormones,hypealbuminemia and invasive operation.The therapy on fungi is focused on pathogen treatment such as anti-fungal drug therapy.
