Distinctive sleep complaints and polysomnographic findings in antibody subgroups of autoimmune limbic encephalitis.

Introduction: Sleep disturbances are being increasingly recognized in association with autoimmune encephalitis (AIE). We investigated the prevalence of sleep-related symptoms and polysomnographic features of patients with AIE and the long-term outcomes in these patients in a multi-center, prospective study from Turkey.

Methods: We prospectively evaluated patients with definite AIE in a common database including demographics, AIE-related and sleep-related symptomatology.

Predictive value of red cell distribution width for overlap syndrome in obstructive sleep apnea.

Purpose: Obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) are prevalent disorders, and the concurrence so-called overlap syndrome (OVS) is not rare either. Early recognition of OVS is essential because this group is more prone to cardiovascular morbidities and requires effective multidisciplinary follow-up. This study aimed to evaluate RDW in patients with severe OSAS and investigate whether it can predict OVS.

Rapid eye movement dependency is associated with increased inflammatory activity in obstructive sleep apnea syndrome.

Objective: Rapid eye movement (REM)-dependent obstructive sleep apnea syndrome (OSAS) is a specific subtype of OSAS having some phenotypic characteristics like a preference for a younger age, female gender, and milder severity. Such favorable features could make it possible to consider an overall benign course for this phenotype. However, accumulating data introduced its association with several cardiometabolic and vascular disorders recently.

The impact of nasal use of azelastine and mometasone furoate on drug-induced sleep endoscopy.

Objective: Endoscopic evaluation becomes difficult when excessive secretion/hypersalivation occurs in the upper airway. Intranasal corticosteroids and antihistamines reduce symptoms of rhinorrhea and nasal congestion. For this reason, in our study, we aimed to examine the effects of mometasone furoate and azelastine on both the amount of secretion and upper airway obstruction in terms of possible benefits during drug-induced sleep endoscopy (DISE).
