AbstractIntroductionSARS-COV-2 causing COVID19 is more transmissible because of two main reasons, which include its ability to bind with receptors of host cell and other being viral load in COVID-19 positive patients which is higher, specifically in throat and nose after developing symptoms.Laryngopharyngeal reflux (LPR) is defined as the reverse flow of abdominal contents into the oropharynx and or nasopharynx and larynx.Recent studies on COVID 19 have documented that LPR may be related with this viral infection. No previous studies have documented incidence of LPR. Our study was an effort to establish the incidence of LPR in COVID 19 positive hospital patients.
Aimof the study
The aim of the study was to evaluate the incidence of laryngopharyngeal reflux (LPR) in hospitalized Covid-19 patients using Reflux symptom index.
This was a prospective study conducted in tertiary care centre on 402 Covid-19 patients who were hospitalized with minimal symptoms & clinically stable, between April 2020 to July 2020. All 402 patients were assessed for the symptoms of laryngopharyngeal reflux using Reflux symptom index questionnaire (RSI). Reflux symptom index value of more than or equal to 13 is indicative of laryngopharyngeal reflux
Result and discussion
Among 402 patients 102 of them had RSI >/=13, among which 54 were males and 48 were females.In our study 16.6%(n=17) were between the age of 20-30 years, 23.5% (n=24) between 31-40 years, 20.5% (n=21) between 41-50 years,25.4% (n=26)between 51-60 years,9.8% (n=10) between 61-70 years and 3.9% (n=4) in 71-80 years. The most common symptom being foreign body sensation in throat followed by post nasal drip & clearing throat mucus.41.1%(n=42)of the study group had onset of symptoms on 3rd day of being tested positive for COVID 19
This study helped to assess the incidence of LPR in COVID19 positive patients. COVID19 medications, altered dietary and lifestyle habits, stress levels might be a reason for this.
