Combined laryngopharyngeal reflux and obstructive sleep apnea (CLOSA) – Salivary pepsin test for laryngopharyngeal reflux in obstructive sleep apnea patients [PDF]
Tzu Chi Medical JournalObjectives: Reflux disease including gastroesophageal reflux and laryngopharyngeal reflux (LPR) is often found in obstructive sleep apnea (OSA) patients. Endoscopic examination is a gold standard diagnosis for reflux disease.

Effects of pepsin and pepstatin on reflux tonsil hypertrophy in vitro. [PDF]
PLoS ONE, 2018 There is evidence that pepsin can aggravate tonsil hypertrophy. Pepstatin is a potent inhibitor of pepsin activity and could protect patients against reflux tonsil hypertrophy by inhibiting pepsin.

Analyzing pepsin degradation assay conditions used for allergenicity assessments to ensure that pepsin susceptible and pepsin resistant dietary proteins are distinguishable. [PDF]
PLoS ONE, 2017 The susceptibility of a dietary protein to proteolytic degradation by digestive enzymes, such as gastric pepsin, provides information on the likelihood of systemic exposure to a structurally intact and biologically active macromolecule, thus informing on

The In Vitro Effect of Acidic-Pepsin on Nuclear Factor KappaB Activation and Its Related Oncogenic Effect on Normal Human Hypopharyngeal Cells. [PDF]
PLoS ONE, 2016 Extra-esophageal carcinogenesis has been widely discussed in relation to the chronic effects of laryngopharyngeal reflux and most prominently with pepsin historically central to this discussion.

Extra-Esophageal Pepsin from Stomach Refluxate Promoted Tonsil Hypertrophy. [PDF]
PLoS ONE, 2016 Gastroesophageal reflux is associated with numerous pathologic conditions of the upper aerodigestive tract. Gastric pepsin within reflux contributes to immunologic reactions in the tonsil.

Separation of pepsin I, pepsin II A, pepsin II B, and pepsin III from human gastric mucosa [PDF]
American Journal of Physiology-Legacy Content, 1963 Extracts of human gastric mucosa have been fractionated on diethylaminoethyl cellulose to yield three precursors of proteolytic enzymes active at low pH which have been called pepsinogen I, pepsinogen II, and pepsinogen III. Pepsinogen I has been found in the mucosa from all parts of the stomach examined as well as in the proximal duodenum. Pepsinogen
