Gastroesophageal reflux and rhinosinusitis

Area of Science:

• Otolaryngology
• Gastroenterology
• Epidemiology

Background:

• Gastro-esophageal reflux disease (GERD) and chronic rhino-sinusitis (CRS) are common conditions.
• Their co-occurrence can be coincidental or potentially linked by shared pathophysiological mechanisms.
• The relationship between GERD and CRS is a subject of ongoing research and debate.

Purpose of the Study:

• To review the epidemiological, diagnostic, and pathophysiological characteristics of GERD and CRS.
• To examine existing data on the potential role of gastro-esophageal reflux (GER) in CRS pathogenesis.
• To evaluate the evidence for a causal link between GERD and CRS.

Main Methods:

• Literature review of epidemiological, diagnostic, and pathophysiological data for GERD and CRS.
• Analysis of studies investigating the association between GER and CRS.
• Synthesis of evidence regarding a potential causal relationship.

Main Results:

• A causal link between GERD and CRS is not yet definitively established.
• Some studies suggest a correlation between GERD and CRS.
• GERD and CRS share common risk factors and potential pathophysiological pathways.

Conclusions:

• While a direct causal relationship between GERD and CRS remains controversial and insufficiently documented, a correlation is indicated by some research.
• Anti-reflux interventions should be considered as a potential therapeutic option for CRS.
• This approach may be particularly beneficial for patients with CRS refractory to conventional treatments.
