Abstract: Objective: To study the relationship between pepsinogen/pepsin in a mouth swab and clinical gastroesophageal reflux (GER) in preterm infants. Methods: Preterm infants [birth weight (BW) ≤ 2000 grams] on full enteral feeds were enrolled. Mouth swabs from cheek and below the tongue were collected 1, 2 and 3 hours after feeding. An enzymatic assay with substrate FITC-casein was used to detect pepsin A and C activity with further confirmation by Western blot. Blinded investigators reviewed the infant's medical record to clinically diagnose GER. Results: A total of 101 premature infants were enrolled. Pepsinogen/pepsin was detected in 45/101 (44.5%) infants in at least one sample. A clinical diagnosis of GER was made in 36/101 (35.6%) infants. Mouth swabs were positive in 26/36 (72%) infants with clinical GER and only 19/65 (29%) infants without GER (P<0.001). Similarly, the levels of pepsinogen/pepsin A and C were higher in the mouth swabs of infants with clinical GER. Conclusion: The detection of pepsinogen/pepsin in a mouth swab correlates with clinical GER in premature infants.
