چکیده
UNLABELLED The Laryngopharyngeal Reflux (LPR) physiopathology is still unknown. The Epidermal Growth Factor (EGF) is a biologically active salivary protein that aids in the rapid regeneration of the oropharyngeal and upper digestive tract mucosas. Salivary deficiency of this protein in patients with LPR has been demonstrated in previous studies. AIM To compare salivary EGF concentration in patients with LPR before and after treatment. MATERIALS AND METHODS In this prospective study twelve patients with GERD and moderate LPR were studied. Whole saliva samples were collected before and after treatment and salivary EGF concentration was determined using a commercially available ELISA kit (Quantikine). RESULTS There were eleven females and one male among the patients, the mean age was 49 years. The mean pre-treatment salivary EGF concentration was 2,867.6 pg/mL and the mean post treatment EGF concentration was 1,588.5 pg/mL. This difference was statistically significant (p=0.015). DISCUSSION AND CONCLUSIONS Although salivary EGF concentrations are higher before LPR treatment, the concentration is still much lower than the mean salivary EGF concentration in normal individuals without LPR, which suggests a primary disorder of this defense factor in individuals with LPR.

Chronic Laryngitis and Gastroesophageal Reflux Disease
78 INTRODUCTION Gastroesophageal reflux disease (GERD) is implicated in many patients with chronic laryngitis. Ear, nose and throat (ENT) physicians often refer to this condition as laryngopharyngeal reflux (LPR) representing the retrograde movement of gastric contents, including acid, pepsin as well as bile acids, into the laryngopharynx (1,2). Typical LPR symptoms include dysphonia, globus ph...

OBJECTIVES Chronic bacterial infection of the larynx is characterized by long-standing hoarseness and exudative laryngitis. Prolonged antibiotic therapy is required to clear the infection, and methicillin-resistant staphylococcus aureus (MRSA) may be the responsible pathogen. The objective of this study was to describe the presentation, comorbidities, treatment response, and underlying etiology...
متن کاملSalivary transforming growth factor alpha in patients with Sjögren's syndrome and reflux laryngitis.
INTRODUCTION Saliva plays a key role in the homeostasis of the digestive tract, through its inorganic components and its protein growth factors. Sjögren's syndrome patients have a higher prevalence of gastroesophageal reflux disease and laryngopharyngeal reflux. Decreased salivary transforming growth factor alpha levels were observed in dyspeptic patients, but there have been no studies in pati...
متن کاملThe human laryngeal microbiome: effects of cigarette smoke and reflux
Prolonged diffuse laryngeal inflammation from smoking and/or reflux is commonly diagnosed as chronic laryngitis and treated empirically with expensive drugs that have not proven effective. Shifts in microbiota have been associated with many inflammatory diseases, though little is known about how resident microbes may contribute to chronic laryngitis. We sought to characterize the core microbiot...
