Abstract

The value of serum and bronchoalveolar lavage fluid galactomannan (BALF-GM) in diagnosing chronic pulmonary aspergillosis (CPA) remains unclear. Here, we study the diagnostic efficacy of GM in the diagnosis of CPA. We included consecutive treatment-naive subjects with CPA. For calculating the specificity of serum GM, we enrolled diseased controls (minimally symptomatic subjects previously treated for pulmonary tuberculosis, not meeting the criteria for CPA). To calculate the specificity of BALF-GM, subjects with pulmonary disorders other than CPA who underwent bronchoscopy were included. We determined the cutoff of serum and BALF-GM levels using receiver operating characteristic (ROC) curve analysis. We enrolled 243 consecutive treatment-naive subjects (53.5% males) of CPA with a mean (standard deviation) age of 43.6 (14.7) years. Forty-five (60% males; age, 46.7 [15.7] years) and 27 (59.3% males; age, 52.6 [12.8] years) subjects served as controls for serum and BALF-GM, respectively. The best cutoff value for serum and BALF-GM was 0.55 (area under the ROC curve [AUROC], 0.605; sensitivity, 38%; specificity, 87%) and 1.375 (AUROC, 0.836; sensitivity, 68%; specificity, 93%), respectively. At a cutoff value of 2.5, BALF-GM had a sensitivity and specificity of 50% and 100%, respectively. BALF-GM performs better than serum GM and may be helpful in the diagnosis of CPA in selected patients. More studies are required to confirm our findings.
