Correlation Between Nocturnal Oxygen Desaturation and Glycemic Control in Diabetic Patients With Obstructive Sleep Apnea

Completed

• Conditions: Obstructive Sleep Apnea; Diabetes Mellitus, Type 2

• Registration Number: NCT04711083
• Lead Sponsor: Ain Shams University

Brief Summary

Nocturnal reduction in blood oxygen is expected independently associated with the development of worsened glycemic control in individuals with type 2 diabetes mellitus.

The aim of the present study is to assess the correlation between nocturnal oxygen desaturation assessed by overnight pulse oximetry and glycemic control in diabetic patients with obstructive sleep apnea.

Detailed Description

Introduction:

Obstructive sleep apnea syndrome (OSAS) is a prevalent illness showing a heterogeneous symptom presentation, which ranges from low clinical suspicion to evident limitations in the quality of life. The main reasons for this variability relate to its potential association with major concomitant diseases, which include diabetes and a variety of cardiovascular pathologies. (1).

Also, OSA is a known risk factor for many comorbid disorders, causing resistance to conventional treatments and increasing the risk of mortality, which multiplies health care expenditures and even though the distribution of comorbidities differs between men and women, their effect progressively increases with OSA severity (2,3) Occurrence of apneic events and Reduction in blood oxygen and elevations in blood carbon dioxide are sensed by chemoreceptors in the brain and carotid bodies, which trigger brief microarousals and result in sleep fragmentation (4).

Nocturnal reduction in blood oxygen has also been independently associated with the development of worsened glycemic control in individuals with type 2 diabetes (4).

Aim of the work:

to assess the correlation between nocturnal oxygen desaturation assessed by overnight pulse oximetry and glycemic control in diabetic patients with obstructive sleep apnea.

Material and Methods:

This study will be conducted on all patients referred for evaluation of sleep related breathing disorders. All Medical files were reviewed. Data collected included .full medical history, demographics, measurements of weight and height, body mass index in kg/m2, neck circumference (NC), Epworth Sleepiness Scale (ESS) scores, measurements of overnight pulse oximetryglyceminc control (measurement of glycated HB, fasting and 2h postprandial blood sugar)The diagnosis that was concluded after a polysomnography study.
