Clinical Utility of Bronchoalveolar Lavage Pepsin in Diagnosis of Gastroesophageal Reflux among Wheezy Infants

Table 4

Relation between BAL pepsin and GERD diagnostic tests.

		Normal pepsin (%)	Abnormal pepsin (%)
		23 (44.2)	29 (55.8)
Combined; MII-pH	+ve	13 (56.5)	21 (72.4)	0.23
	−ve	10 (43.5)	8 (27.6)
Reflux; esophagitis	+ve	5 (21.7)	13 (44.8)	0.14
	−ve	18 (78.3)	16 (55.2)
LLMI	≥100	6 (26.1)	14 (48.3)	0.15
	100	17 (73.9)	15 (51.7)

LLMI, lipid laden macrophage index; MII-pH, multiple intraluminal impedance-pH monitoring. No significant relation occurs between abnormal BAL pepsin and abnormal combined MII-pH, reflux esophagitis, and LLMI ≥ 100.
