Special Staining of the Liquid-Based Cytopathology Test in Bronchoalveolar Lavage Fluid for Diagnosis of Invasive Pulmonary Aspergillosis with Nonneutropenic Patients

Table 5

Comparison of recent studies on the positive rate of LCT in BAL fluid in the diagnosis of IPA.

	Sample type	n	Special staining of LCT
			PAS and GMS both positive	Only PAS positive	Only GMS positive
Shen et al. [4]^a	Bronchial brushing	54	83.33% (45/54)	—	—
	Sputum	117	43.59% (51/117)	—	—
Jiang et al. [17]^b	Bronchial brushing	33	87.88% (29/33)	—	—
Our study	BAL fluid	49	—	81.58%	92.11%

^aShen et al. studied the role of LCT in the diagnosis of IPA in bronchial brushing specimens and sputum specimens. ^bJiang et al. studied the role of LCT in the diagnosis of pulmonary mucormycosis in bronchial brushing samples. LCT: liquid-based cytopathology test; PAS: periodic acid-Schiff; GMS: Grocott’s methenamine sliver; BAL: bronchoalveolar lavage; IPA: invasive pulmonary aspergillosis.
