Severe Sleep Apnea Linked to Increased Beta-Amyloid in Brain

A new study by Monash University has found that obstructive sleep apnea (OSA) has been linked to an increased risk of dementia.

The study, published in the Journal of Alzheimer’s Disease, and led by Melinda Jackson, PhD, from the Turner Institute for Brain and Mental Health, found that severe OSA is linked to an increase in the protein beta-amyloid, which builds up on the walls of the arteries in the brain and increases the risk of dementia.

The study involved 34 individuals with recently diagnosed untreated OSA and 12 individuals who were asymptomatic for sleep disorders. It explored associations between brain amyloid burden using a PET brain scan, and measures of sleep, demographics, and mood.

The OSA group recorded a higher amyloid burden, poorer sleep efficiency, and less time spent in stage N3 sleep.

“The significance of finding the association between increased brain amyloid in patients with OSA will allow for further research to explore in more detail the implications of treating OSA for reducing dementia risk,” Jackson …

First Patient Dosed in Sleep Apnea Pill Phase 2 Clinical Trial

The first patient has been dosed in a Phase 2 clinical trial evaluating AD109, Apnimed’s first-in-class oral pharmaceutical under development for the treatment of obstructive sleep apnea (OSA).

“There is a clear unmet need for an approach that addresses the underlying cause of OSA,” says Larry Miller, MD, Apnimed CEO, in a release. “Evidence from earlier proof-of-concept studies demonstrated the potential of our oral therapy as an option for the treatment of OSA. We anticipate data from this Phase 2 study in the first half of 2021 and plan to move forward into a Phase 3 registrational study in 2021.”

AD109 combines a selective norepinephrine reuptake inhibitor (atomoxetine) with a novel new chemical entity (NCE)—a selective antimuscarinic (aroxybutynin). Proof-of-concept for the AD109 program was demonstrated by Apnimed in a Phase 2, parallel group dose-finding study of the combination of atomoxetine and racemic oxybutynin. That study provided evidence of safety and efficacy in the treatment of OSA with a norepinephrine reuptake inhibitor (NRI) + antimuscarinic combination in 140 patient—indicating that a pharmacologic approach could treat the underlying pathophysiology of OSA. AD109 …

First Patient Enrolls in Central Sleep Apnea Trial to Assess Alternative Transvenous Lead Location for Remedē Implant

Bryn Mawr Hospital, part of Main Line Health’s Lankenau Heart Institute, on August 18, 2020 became the first site in the world to successfully enroll a patient and complete the protocol in JANUS, a clinical trial for sleep apnea. The trial seeks to explore whether transvenous stimulation can improve airway physiology. In this first patient, Sheetal Chandhok, MD, the investigator and implanting physician, was able to demonstrate feasibility in this novel approach for managing sleep apnea.

The primary objective of the JANUS trial, sponsored by Respicardia, is to assess acute changes in respiration and airway physiology during sleep. The trial is being conducted in patients with central sleep apnea who are undergoing a Remedé system implant, which uses transvenous stimulation to reduce the periods of the breathing pauses. The JANUS trial is conducted during the implantation of commercially available device called the Remede System, a diaphragm pacemaker that works to stimulate breathing in the same way that the brain would. The Remede System was first implanted at Bryn Mawr Hospital by Chandhok, a cardiac electrophysiologist, in January 2019.

Beyond AHI: The Future of Endophenotyping in Sleep Medicine

Researchers make strides in scaling obstructive sleep apnea endotyping, which may guide therapy choices once more data becomes available.  

By Lisa Spear

The pathophysiology behind every patient’s obstructive sleep apnea (OSA) is unique. Not every airway collapses in the same way or for the same reasons, but often OSA cases are treated and studied without considering the specificities of each person’s anatomy.

In the research community, there’s been a decent amount of interest in OSA phenotyping to hone in on the causes of sleep apnea. Now, an emerging computer program could change the way sleep scientists think about the study of sleep-disordered breathing by making endophenotyping easier to deploy on a large scale. The new tool called PUPpy uses algorithms to analyze large data sets from polysomnograms (PSG) to derive respiratory endotypes, according to recently published research in the journal SLEEP.

“With the respiratory endotyping that we have been working on, our goal is to help doctors answer why different patients have sleep apnea as opposed to whether or not they have it. That is not currently available …

Sleep Apnea & Autoimmune Disease: A New Study Explores Cytokines 0

Sleep Apnea & Autoimmune Disease: A New Study Explores Cytokines

New research by University of Georgia scientists sheds light on why people with obstructive sleep apnea may have associated autoimmune disorders. The results could lead to better approaches to treatment and possibly new drug therapies.

The study, led by Bradley Phillips, PharmD, BCPS, FCCP, builds on previous research showing that obstructive sleep apnea (OSA) increases the risk for autoimmune diseases. Immune system disorders are a result of either low activity or over activity of the immune system and include well-known conditions such as lupus and rheumatoid arthritis. The molecular links to autoimmunity are poorly understood.

“This paper looks at what may be the underlying mechanisms that increase someone’s risk for autoimmune disorders because they have untreated obstructive sleep apnea,” says Phillips, director of UGA’s Biomedical and Health Sciences Institute, in a release.

Phillips and the team looked at four cytokines—proteins involved in cell signaling—associated with autoimmune disease. They evaluated the cytokines in three groups of adults: patients with untreated OSA, patients with OSA who were receiving treatment, and people who did not have OSA. The study results revealed abnormal levels …

AADSM: Dentists Can Order Home Sleep Tests

A new position statement from the American Academy of Dental Sleep Medicine supports qualified dentists’ ability to order or administer HSTs. Not everyone agrees.

By C.A. Wolski

The American Academy of Dental Sleep Medicine (AADSM) recently made its position clear:

“[I]t is within the scope of practice for a qualified dentist, defined by the American Dental Association (ADA) as a dentist treating sleep-related breathing disorders who continually updates his or her knowledge and training of dental sleep medicine with related continuing education, to order or administer home sleep apnea tests (HSATs).”1

This position statement, which is diametrically opposed to the stance of the American Academy of Sleep Medicine (AASM), has already had a polarizing effect. But David Schwartz, DDS, president of the AADSM and statement co-author, isn’t swayed: Taking a strong stance was exactly the point.

“Effective positions are intended to be bold and often groundbreaking,” Schwartz says. “The number of dentists deemed qualified by the AADSM to treat patients diagnosed with sleep apnea and snoring has increased to more than 1,600. Correspondingly, the number of undiagnosed patients …
