| Summary: | Background
Non erosive reflux Disease (NERD) has emerged as a real entity in the spectrum of gastroesophageal
reflux disease (GERD).It may potentially represent the most common manifestation of reflux disease.
Although numerous studies had been performed on NERD,none of the the studies had explored the
expression of TRPV4 as a causative factor and the link between pH study and manometry. This
knowledge is beneficial for new targeted treatment.
Methodology
This was a prospective study that was done on NERD and control patients from March 2017 until
November 2017. A total of 55 patients - 39 NERD and 16 control patients were investigated. All
patients had undergone EGD and multiple biopsies were taken. Notably, erosive esophagitis patients
were excluded. Apart from that, the patients also went through pH study and manometry.
Results
The result from this research we showed that TRPV4 was expressed in both NERD and control
patients. No association was discovered between TRPV4 and NERD, as well as among pH study,
manometry and endoscopic features. Futhermore, TRPV4 was found to be higher in cells from the
normal group as compared to the NERD group. Notably, p-value was insignificant but this may be
caused by small sample size
Conclusion
This study was performed to determine the association between TRPV4 and NERD. No significant
association was revealed between the expression of of TRPV 4 and the NERD group. Similarly, other
parameters from pH study, manometry and endoscopic finding also did not show any significant
association with TRPV4. |
