Obstructive sleep apnea is highly prevalent in COVID19 related moderate to severe ARDS survivors: findings of level I polysomnography in a tertiary care hospital

Abstract: Study Objectives Studies have found Obstructive Sleep Apnea (OSA) as a risk factor for increased risk for COVID19 Acute respiratory Distress Syndrome (ARDS); but most of the studies were done in already known patients of OSA. This study was done to find prevalence of OSA in patients with COVID-19 related acute respiratory distress syndrome. Methodology A hospital based longitudinal study was conducted among COVID 19 Intensive Care Unit (ICU) survivors. All consecutive C… Show more

“…A high prevalence of moderate to severe OSA (obstructive sleep apnoea) of 73% was observed. As noted by the authors, untreated OSA could lead to cardiac complications and persistent symptoms such as fatigability and insomnia, thus partially explaining the increased prevalence of these symptoms in COVID-19 survivors [ 137 ].…”

“…First, the comorbidities of obstructive sleep apnea, such as obesity and hypertension are same as poor outcomes of COVID-19 infection. 7,23,26 Second, the Renin-Angiotensin system (RAS) pathway dysregulation and angiotensin II elevation due to sleep interruption noted in patients with obstructive sleep apnea, which is likely to cause COVID-19 infection more easily. 23,24 Third, increased IL-6 and TNF-αlevel in patients with obstructive sleep apnea are prone to induce inflammatory reaction which resulted in more severe complications after COVID-19 infection.…”

“…Our study can be compared to 2 others based on the same diagnosis criteria of SA using poly(somno)graphy. 44 , 45 The first study conducted by Labarca et al 44 evaluated a cohort of COVID-19 patients 3 and 6 months after diagnosis. Thirty-four patients with COVID-19 ARDS were compared with a control group of 28 patients with mild to moderate COVID-19 symptoms.…”

“…The prevalence of OSA (79%) was lower than in our study, perhaps because COVID-19 infection was less severe in their patients, as reflected by a higher mean DLCO (85.5% (±22.6) vs 77.65% (±21.14) of predicted), fewer persistent CT abnormalities (67.6% vs 95.2%), a higher mean distance on 6MWT (509 meters (±121.9) vs 480.56 (±120.46)), less frequent intubation (70.5%), curarization (52.9%), prone positioning (41.1%), and shorter duration of ICU stay (10.8±8.9 days) and overall hospitalization (23.8±21). The second study by Goyal et al 45 was an Indian hospital-based longitudinal study conducted among COVID-19 ICU survivors followed over a period of two months. All consecutive COVID-19 patients with moderate to severe ARDS were evaluated 4–6 weeks after ICU discharge.…”
