Abstract:
Objective To demonstrate the clinical characteristics and prognosis of invasive pulmonary aspergillosis (IPA) in respiratory intensive care unit (ICU), for early diagnosis and treatment. Methods The clinical features, treatment and outcome of 17 patients diagnosed as IPA in RICU from May 2015 to April 2018 were analyzed retrospectively. Results The basic diseases of 17 patients were mostly chronic respiratory diseases (14 cases, while 11 cases were chronic obstructive pulmonary disease). One case was proven by IPA criteria, 13 cases were probable and 3 cases were possible. All patients were treated with broad-spectrum antibiotics during hospitalization, and 6 patients were treated with glucocorticoids (oral/intravenous) within 3 weeks of admission and during hospitalization. The main clinical symptoms included cough sputum, dyspnea and fever, among which 4 cases had hemoptysis. Infiltrates were seen in 8 cases, multiple nodules with cavitary lesions in 4 cases, multiple small nodules along the bronchi in 2 cases, and left upper lobe consolidation in the proven case. Sixteen patients were treated with voriconazole alone or in combination with caspofungin. Fourteen patients were tested for voriconazole serum concentration, while 4 were in normal range, 10 were elevated (2 cases were significantly elevated, ＞10 μg/L). Serum concentration of bilirubin did not increase significantly in all paitents after treatment. Serum concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated in 4 cases with elevated serum concentration of voriconazole and 2 cases with normal serum concentration of voriconazole. Patients with elevated voriconazole concentration did not show significant difference in prognosis compared with those with normal concentration. Eight cases were improved and discharged and 9 gave up and died due to the worsening of the disease. Eight patients received mechanical ventilation (6 cases were invasive and 2 cases were non-invasive), 7 of them eventually gave up treatment and died. Conclusions The clinical features of chronic respiratory diseases with IPA are atypical, however, the patient is critically ill with high mortality. Elevated serum concentration of voriconazole might be more common in severe patients. For those who have a history of systemic application of glucocorticoids, clinical symptoms with hemoptysis, short of breath, radiology with infiltrates, nodular and/or with cavity, and with no response to antibiotics, clinicians should actively seeking evidence of IPA, for early diagnosis, standardized treatment, and improve the prognosis of patients with chronic respiratory diseases complicated with IPA.
