Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
Other Pulmonary Disorders01:17

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
Sleep-Wake Cycles01:24

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:
Chronic Obstructive Pulmonary Disease-II: Pathophysiology01:20

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:
Chronic Inflammation
Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...
Pneumothorax II: Pathophysiology01:08

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...

Summary

Patients with sarcoidosis often experience fatigue and excessive daytime sleepiness due to a higher prevalence of obstructive sleep apnoea (OSA). Screening for OSA and treatments like CPAP can improve quality of life.

Area of Science:

  • Pulmonary Medicine
  • Sleep Medicine
  • Immunology

Background:

  • Sarcoidosis is a multisystem granulomatous disease with unknown cause, frequently impacting lungs.
  • Fatigue and excessive daytime sleepiness (EDS) are common, disabling symptoms in sarcoidosis patients, persisting even with stable disease.
  • Obstructive sleep apnoea (OSA) is increasingly recognized as prevalent in sarcoidosis, linked by inflammation, corticosteroid therapy, and airway involvement.

Purpose of the Study:

  • To explore the complex association between sarcoidosis and obstructive sleep apnoea (OSA).
  • To understand the contributing mechanisms linking sarcoidosis and OSA.
  • To highlight the importance of OSA screening and treatment in sarcoidosis patients with sleep-related symptoms.

Main Methods:

  • Review of existing clinical studies and evidence.
  • Analysis of shared inflammatory pathways and treatment side effects.
  • Assessment of upper airway involvement and pulmonary function in sarcoidosis patients.

Main Results:

  • Sarcoidosis patients exhibit a higher prevalence of OSA than the general population, including non-obese and treatment-naïve individuals.
  • Mechanisms include shared inflammation, corticosteroid-induced weight gain/myopathy, upper airway sarcoidosis (SURT), and restrictive lung disease.
  • Continuous Positive Airway Pressure (CPAP) therapy improves fatigue, EDS, and quality of life in these patients.

Conclusions:

  • OSA is a significant contributor to fatigue and EDS in sarcoidosis.
  • Systematic OSA screening is crucial for sarcoidosis patients with persistent sleep symptoms.
  • Further research is needed on OSA treatment impact and adjunctive therapies like solriamfetol and pitolisant.
