: Sleep-disordered breathing (SDB) is now a significant health problem in today's culture. It ranges from a spectrum of abnormal conditions during sleep from the primary snorer to mild, moderate, or severe obstructive sleep apnea (OSA). SDB also comprises other conditions, such as sleep-related hypoventilation, sleep-related hypoxemia, and central sleep apnea syndromes. One of the components of the pathophysiology of OSA that remain unclear is the association of allergic rhinitis (AR) in the evolution of OSA. Several studies relate OSA and AR's co-existence in the common clinical practice, but its correlation was not clear. This review article aimed to review the relationship between OSA and AR in terms of the role of chemical mediators and pathophysiological and the effect of AR treatment in support of OSA. The symptoms of AR further accelerate the clinical progression to OSA development. Inflammatory mediators such as histamine, cysteinyl leukotrienes, and interleukins are found at a high level in AR, which can aggravate AR symptoms such as nasal obstruction, rhinorrhea, and itchiness, which can then lead to sleep disruption in OSA patients. In addition, OSA patients also have increased chemical mediators such as tumor necrosis factor, interleukin 6, and 1, which would activate the T helper 2 phenotypes that can aggravate AR symptoms. This vicious cycle can potentiate each other and worsen the condition. Few studies have shown that treatment of AR can improve OSA, especially the use of intranasal steroid and leukotriene receptor antagonists. A detailed evaluation of rhinitis symptoms should be made for those OSA patients so that they can benefit not only from the improvement of AR but also the good sleep quality.

Abstract Introduction Sleep-disordered breathing is common in persons with multiple sclerosis (PwMS), and may contribute to debilitating fatigue and other chronic MS symptoms. The majority of research to date on SDB in MS has focused on the prevalence and consequences of obstructive sleep apnea; however, PwMS may also be at increased risk for central sleep apnea (CSA), and the utility of methods to assess CSA in PwMS warrant further exploration. We present a patient with secondary progressive multiple sclerosis who was found to have severe central sleep apnea on WatchPAT testing. Report of case(s) A 61 year-old female with a past medical history of secondary progressive multiple sclerosis presented with complaints of fragmented sleep. MRI of the brain, cervical spine, and thoracic spine showed numerous demyelinating lesions in the brain, brainstem, cervical, and thoracic spinal cord. Upon presentation, the patient noted snoring, witnessed apneas, and daytime sleepiness. WatchPAT demonstrated severe sleep apnea, with a pAHI of 63.3, and a minimum oxygen saturation of 90%. The majority of the scored events were non-obstructive in nature (73.1% of all scored events), and occurred intermittently in a periodic fashion. Conclusion The differential diagnosis of fatigue in PwMS should include sleep-disordered breathing, including both obstructive and central forms of sleep apnea. Demyelinating lesions in the brainstem (which may contribute to impairment of motor and sensory networks that control airway patency and respiratory drive), and progressive forms of MS, have been linked to both OSA and CSA. The present data illustrate this relationship in a person with progressive MS, and offer support for the WatchPAT as a cost-effective means to evaluate for both OSA and CSA in PwMS, while reducing patient burden. PwMS may be at increased risk for CSA. Careful clinical consideration should be given to ordering appropriate sleep testing to differentiate central from obstructive sleep apnea in PwMS, particularly for patients with demyelinating lesions in the brainstem.

Brainstem Evoked Potentials

Brainstem evoked potentials (BSEP) were recorded in 23 patients with adult sleep apnea (ASA). These patients were studied with all-night polysomnography prior to our testing. They were categorized as having obstructive, central, or mixed sleep apnea depending on the predominant sleep findings. All patients with central sleep apnea had abnormal BSEP with prolongation of wave V. A majority of the remaining patients with obstructive sleep apnea and mixed sleep apnea had abnormal BSEP, but without specific configurations. These findings substantiate our hypothesis that brainstem dysfunction may play a role in ASA.

Abstract Introduction The apnea-hypopnea index (AHI) is used as a generic index to quantify both central sleep apnea (CSA) and obstructive sleep apnea (OSA) syndromes. Patterns of oxygenation abnormalities seen in CSA and OSA may be key to understanding differing clinical impacts of these disorders. Oxygen desaturation and resaturation slopes and durations in OSA and CSA were compared between OSA and CSA patients. Methods Polysomnographic data of patients aged 18 years or older with diagnosis of OSA and CSA, at University of Iowa Hospitals and Clinics, were analyzed and demographic data were collected. Oximetric changes during hypopneas and apneas were studied for desaturation/resaturation durations and desaturation/resaturation slopes. Desaturation and resaturation slopes were calculated as rate of change in oxygen saturation (ΔSpO2/Δtime). Comparison of hypoxemia-based parameters between patients with OSA and CSA was performed using unpaired t-test. Results 32 patients with OSA with median AHI of 15.4 (IQR 5.1 to 30.55) and median ODI of 15.47 (IQR 9.50 to 29.33) were compared to 15 patients with CSA with a median AHI of 20.4 (IQR 12.6 to 47.8) and median ODI of 27.56 (IQR 17.99 to 29.57). The mean number of desaturation and resaturation events was not significantly different between patients with OSA and CSA (OSA - 106.81±87.93; CSA - 130.67±76.88 with a p-value 0.1472). 4/15 CSA patients had Cheyne-Stokes breathing, 2/15 had treatment emergent central sleep apnea, 1/15 had methadone-associated CSA and for 8/15, no etiologies for CSA were found. Mean desaturation durations was significantly longer in OSA (20.84 s ± 5.67) compared to CSA (15.94 s ± 4.54) (p=0.0053) and consequently the desaturation slopes were steeper in CSA than OSA (-0.35%/sec ±0.180 vs. -0.243 ± 0.073; p=0.0064). The resaturation duration was not significantly longer in OSA (9.76 s ± 2.02) than CSA (9.057 s ± 2.17) (p=0.2857). Differences between desaturation duration and slopes between CSA and OSA persisted during REM and NREM sleep, and in supine sleep. Conclusion As compared to OSA, patients with CSA have different patterns of desaturations and resaturations with lesser hypoxic burden with CSA. This may have implications on the clinical outcomes seen between these two disorders. Support (if any):

Rapid assessment of breathing patterns is important for several emergency medical situations. In this research, we developed a non-invasive breathing analysis system that automatically detects different types of breathing patterns of clinical significance. Accelerometer and gyroscopic data were collected from light-weight wireless sensors placed on the chest and abdomen of 100 normal volunteers who simulated various breathing events (central sleep apnea, coughing, obstructive sleep apnea, sighing, and yawning). We then constructed synthetic datasets by injecting annotated examples of the various patterns into segments of normal breathing. A one-dimensional convolutional neural network was implemented to detect the location of each event in each synthetic dataset and to classify it as belonging to one of the above event types. We achieved a mean F1 score of 92% for normal breathing, 87% for central sleep apnea, 72% for coughing, 51% for obstructive sleep apnea, 57% for sighing, and 63% for yawning. These results demonstrate that using deep learning to analyze chest and abdomen movement data from wearable sensors provides an unobtrusive means of monitoring the breathing pattern. This could have application in a number of critical medical situations such as detecting apneas during sleep at home and monitoring breathing events in mechanically ventilated patients in the intensive care unit.
