Summary
Psoriasis and obstructive sleep apnea (OSA) have a confirmed bidirectional link. This systematic review found increased odds of OSA in psoriasis patients and increased psoriasis risk in OSA patients.
Area of Science:
- Dermatology and Sleep Medicine
Background:
- The association between psoriasis and obstructive sleep apnea (OSA) remains unclear.
- Psoriasis is a chronic inflammatory skin condition.
- OSA is a common sleep-related breathing disorder.
Purpose of the Study:
- To systematically investigate the bidirectional relationship between psoriasis and OSA.
- To synthesize evidence from multiple study designs.
Main Methods:
- Systematic review and meta-analysis of case-control, cross-sectional, and cohort studies.
- Searched MEDLINE and Embase databases.
- Assessed study bias using the Newcastle-Ottawa Scale.
- Employed random-effects models for meta-analysis.
Main Results:
- Included 4 case-control/cross-sectional studies and 3 cohort studies (5,840,495 subjects).
- Found significantly increased odds of OSA in psoriasis patients (OR 2.60).
- Identified a significantly increased risk of psoriasis in OSA patients (IRR 2.52).
Conclusions:
- Established a bidirectional association between psoriasis and OSA.
- Recommends inquiring about sleep quality in psoriasis patients.
- Suggests considering sleep studies for OSA symptoms in psoriasis patients.

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.

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.

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.

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).
