The Effect of Early Radiofrequency Turbinate Reduction on Persistent Allergic Rhinitis

Phase 3
Completed
Conditions
Allergic Rhinitis
Interventions
Drug: Pharmacology treatment
Procedure: Radiofrequency turbinate reduction
Registration Number
NCT05276336
Lead Sponsor
Indonesia University
Brief Summary

The primary outcome of this study is to evaluate the effect of radiofrequency turbinate reduction as an initial treatment on clinical improvement (using visual analogue scale based on total nasal symptoms score, peak nasal inspiratory flow, and turbinate size using ImageJ), inflammatory mediators (ELISA from nasal secretions was performed to measure ECP, IL-5, and HSP-70), and remodeling markers (through nasal biopsy followed by immunohistochemistry examination to evaluate MMP-9, TIMP-1, and PAI-1).

In this randomized, controlled trial, 32 patients with moderate-severe persistent AR were randomly divided into 2 groups. Intervention group received radiofrequency turbinate reduction followed by intranasal steroid and antihistamine H-1(AH-1), control group received intranasal steroid and AH-1. Both groups were evaluated for clinical improvement in week 4 and 8 after treatment, inflammatory mediators and remodeling markers in week 4 after treatment.

Detailed Description

The study compares 2 groups of moderate-severe persistent allergic rhinitis (AR). The intervention group receives radiofrequency turbinate reduction followed by pharmacology treatment (intranasal steroid and AH-1) while the control group receives only pharmacology treatment.

Diagnosis of AR will be made through clinical history, physical examination, and skin puncture test. Patients aged 18-55 years old with moderate-severe persistent AR who come to the outpatient clinic and have signed the informed consent form will be included in this study. Moderate-severe AR is defined as having AR symptoms for more than 4 days in a week and more than 4 weeks, with symptoms affecting the subjects' quality of life. Patients will be assigned to two groups of treatment randomly with a single blind block randomization.

Primary Outcome Measures
NameTimeMethod
VAS score based on TNSS at baselineEvaluation is done at baseline

Clinical symptoms was evaluated by visual analogue scale (VAS) based on total nasal symptoms score (TNSS). Total nasal symptoms score are based on four symptoms, which are rhinorrea, sneezing, itchy nose, and nose obstruction. Each symptom will be given a score between 1 (most mild symptom) until 5 (most severe symptom). The minum score for VAS based on TNSS is 4 (most mild symptom) and the maximum score is 40 (most severe symptom). VAS score less than five indicates a controlled rhinitis allergy symptoms, while ≥ 5 indicates that symptoms are not controlled.

VAS score based on TNSS at week 4Evaluation is done at week 4

Clinical symptoms was evaluated by visual analogue scale (VAS) based on total nasal symptoms score (TNSS). Total nasal symptoms score are based on four symptoms, which are rhinorrea, sneezing, itchy nose, and nose obstruction.

VAS score less than five indicates a controlled rhinitis allergy symptoms, while ≥ 5 indicates that symptoms are not controlled.

Size of inferior turbinate at baselineEvaluation is done at baseline

The inferior turbinate was evaluated by using nasoendoscopy and Image J™ program was used to determine the size of inferior turbinate.

Size of inferior turbinate at week 4Evaluation is done at week 4

The inferior turbinate was evaluated by using nasoendoscopy and Image J™ program was used to determine the size of inferior turbinate.

Size of inferior turbinate at week 8Evaluation is done at week 8

The inferior turbinate was evaluated by using nasoendoscopy and Image J™ program was used to determine the size of inferior turbinate.

PNIF value at week 8Evaluation is done at week 8

Nasal airflow resistance was evaluated using In-Check Nasal Inspiratory Flow Meter by Clement Clarke International Itd England. The examination was repeated for three times with 30 seconds paused and the highest value was taken.

Remodeling components at week 4Evaluation is done at week 4

Remodeling components that will be evaluated are MMP-9, TIMP-1, and PAI-1. They will be assessed using immunihistochemistry from tissue biopsy of inferior turbinate.

VAS score based on TNSS at week 8Evaluation is done at week 8

Clinical symptoms was evaluated by visual analogue scale (VAS) based on total nasal symptoms score (TNSS). Total nasal symptoms score are based on four symptoms, which are rhinorrea, sneezing, itchy nose, and nose obstruction.

Inflammatory mediators at baselineEvaluation is done at baseline

Inflammatory mediators that will be evaluated are IL-5, ECP, and HSP-70. They were examined from nasal secretions and enzyme-linked immunosorbent assay (ELISA) spectrophotometry is used to evaluate the amount of IL-5, ECP, and HSP-70 in both groups
