Effectiveness of Sodium Hyaluronate In Relieving Nasal Symptoms Of Children With Seasonal Allergic Rhinitis

Summary

Nasal irrigation (NI) is recommended as an add-on therapy in patients with allergic rhinitis (AR). The primary purpose of this study was to evaluate the clinical effectiveness of adding hyaluronic acid (HA) solution and normal saline (NSS) to nasal steroid (NS) therapy as add - on therapy in improving quality of life and reducing nasal symptom scores of children with seasonal AR (SAR) with regards to NS therapy. Our secondary purpose was to demonstrate the effects on eosinophil count in nasal cytology (NEC), nasal airflow (NAF), and resistance (NAR).

Conditions

• Seasonal Allergic Rhinitis

Interventions

OTHER

"Total nasal symptom score" (TNSS)

TNSS contains 4 parameters in assessing the severity of allergic rhinitis: nasal congestion, runny nose, nasal itching, and sneezing. Each symptom is scored out of 4 points, from 0 to 3. 0, none- there are no complaints 1- mild- any symptom that exists but is not particularly annoying; 2, moderate, - any annoying symptom but does not interfere with daily activities or sleep; 3, severe - any symptom preventing daily activities or disturbing during sleeping. The total score is calculated by summing all the scores of 4 fields, which vary ranges from 0 to 15 .In our study, all patients will be instructed to record their TNSS symptom scores on their diary cards each morning before taking the drug. Patients will be graded on baseline TNSS parameters compared to 4 weeks before starting treatment.

BEHAVIORAL

Paediatric Rhinoconjunctivitis Quality of Life Questionnaire" (PRQLQ)

PRQLQ, is a self-administered, disease-specific questionnaire, evaluating physical, emotional, and social status of individuals with AR. It contains 23 items in 5 domains: nose symptoms (RS), eye symptoms (ES), practical problems (PF), activity limitation (RL) and other symptoms (OS). One score is given to each domain. 7-point scale (from 0, not problematic; to 6, very problematic). The overall score is derived from the average score of all items (20). In our study, the Turkish validated form of PRQLQ was used Patients will be asked to answer PRQLQ questions at the end of each week during treatment. At the end of the treatment, an average of 4 weeks will be taken as the PRQLQ score. Basal PRQLQ questions will be evaluated by the participants based on 4 weeks prior to treatment.

DIAGNOSTIC_TEST

Nasal cytology

In anterior rhinoscopy, nasal cytology will be scraped off the middle part of the lower turbinate with the help of a small sterile cotton swab. The cellular material obtained will be fixed by air drying on a glass slide and then stained by the May-Grünwald-Giemsa method. Preparations that do not contain respiratory epithelium or contain less than 10 epithelium at high magnification will be excluded from the study. A percentage of cells per 100 cells will be reported. NECs (nasal eosinophilic count) will be evaluated according to the quantitative classification of Gelardi et al. An experienced cytologist who is blind to the study groups will perform this test. Eosinophil percentages in nasal smears of all patients will be evaluated before and after the treatment.

DIAGNOSTIC_TEST

anterior rhinomanometry

Children's right, left and total nasal airway resistance (NAR) and nasal airflow (NAF) will be measured with active anterior rhinomanometry ZAN 100 USB Rhinomanometry (Longmont, Colo., USA). In the evaluation, the NAR- pressure difference / air flow (R = P / V) formula will be used at a constant 150 Pascal prescribed by the European Rinomanometry Standardization Committee in 1984. After the patient is rested for 20 minutes, measurements will be made at 20-22 ° C and the nasal secretion will be cleared. NAR and NAF values of the participants will be measured before starting treatment and 4 weeks after treatment.
