Abstract

Background

Although the role of neurotrophins such as nerve growth factor and brain-derived neurotrophic factor in nasal polyps development has been studied, the contribution of neurotrophin-3 has not been evaluated yet. This study aimed to investigate the possible role of neurotrophin-3 in nasal polyps pathogenesis.

Methods

The study group comprised 70 non-allergic nasal polyps patients and the control group consisted of 53 patients with middle turbinate concha bullosa. Specimens were taken, during surgery, from the ethmoid sinus nasal polyps in the nasal polyps group and from the lateral part of the middle turbinate concha bullosa in the control group. Tissue and serum levels of neurotrophin-3 were assessed by immunohistochemistry and enzyme-linked immunosorbent assay, respectively.

Results

Nasal polyps patients had higher tissue neurotrophin-3 scores (p < 0.001). There was no statistically significant difference between groups regarding serum neurotrophin-3 levels (p = 0.417). Tissue neurotrophin-3 staining scores in the nasal polyps group had no statistically significant correlation with Lund–Mackay scores (p = 0.792).

Conclusion

Neurotrophin-3 may have a local effect in nasal polyps pathogenesis, without joining systemic circulation.
