The Effect of Early Radiofrequency Turbinate Reduction on Persistent Allergic Rhinitis

17 mars 2022 mis à jour par: Nina Irawati, Indonesia University

The Effect of Early Radiofrequency Turbinate Reduction, Intranasal Steroid, and Antihistamine H-1 on Persistent Allergic Rhinitis: A Randomized Clinical Trial

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.

Aperçu de l'étude

Description détaillée

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.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Intervention Group
Subjects will receive radiofrequency turbinate reduction done in the outpatient clinic, followed by pharmacology treatment (intranasal steroid and AH-1) for 8 weeks.
Before the radiofrequency turbinate reduction procedure, local anaesthesia will be given by applying a cotton tamponade soaked in lidocaine adrenaline 1:5000 titration and added with xylocaine gel for 10 minutes in both nostrils. Then, a mixture of 1 mL of lidocaine 2% and 2 mL of sodium chloride 0,9% will be infiltrated to both nostrils using 3 mL and 1 mL needles until the inferior turbinates are pale. The radiofrequency probe (made by Sutter, both in monopolar and bipolar modes) will be inserted to the distal inferior turbinate until the black line from the probe is inside the inferior turbinate (approximately 10-12 mm). The procedure will be done for 10 seconds and the insertion of the probe can be done in 2-3 sites. After this, subjects from this group will be treated with pharmacology treatment using intranasal steroid and AH-1 according to ARIA WHO guideline 2008, similar to the pharmacology treatment received by the control group.
Subjects will be treated with intranasal steroid and AH-1 according to ARIA WHO guideline 2008. Fluticasone furoate will be given twice a day with two sprays (100 µg) for each nostril for 2 weeks, then continue for once a day with two sprays (100 µg). Antihistamine H-1 is given 10 mg, once a day. Pharmacology treatment is given for 4 weeks, then intranasal steroid will be continued for another 4 weeks.

Description de la mesure
Délai
VAS score based on TNSS at baseline
Délai: Evaluation 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.
