PURPOSE: Available studies have shown the association of allergic rhinitis and nasal obstruction as a risk factor for sleep disordered breathing. However, it is not clear whether allergic rhinitis constitute as a risk factor for Obstructive Sleep Apnea (OSA). Limited information is available in literature and no data is available from India on this issue so far. This study was carried out to detect the association of OSA in patients with allergic rhinitis

METHODS: This is an observational study in Northern India. We assessed allergic rhinitis patients diagnosed clinically in the outpatient department. The patients after due consent had undergone overnight Polysomnography for evaluation of sleep apnea using the Compumedics E-series-44 Channel Polysomnography System.

RESULTS: Of the 69 subjects (41 Males, 28 Females) who completed the study the mean age was 39.83 (+13.01 years), height 164.3 cm (+9.7cm) and Body mass Index (BMI) was 23.98 (+4.48). All patients were greater than 18 years old. The mean respiratory disturbance index (RDI) was 2.2+ 6.75 (median 0.3). The patients were divided into two groups, RDI < or equal to 5 (n=65) and RDI > 5 ( n=4) . The percentage of population having OSAS in this group was 5.8% which was similar to that of general population (p= 0.717). It was found out that RDI was significantly associated with weight and BMI (p - 0.004 and p- 0.005 respectively)

CONCLUSIONS: We conclude that subjects with allergic rhinitis have marginal increase incidences (but not statistically significant) in our study when compared to the general population. This study was done from mildly symptomatic patients attending the outpatient department and may not be the representative of the whole group of allergic rhinitis population.

CLINICAL IMPLICATIONS: Further large scale multicentre study is needed to ascertain the association.
