Disease State Crossover Managing the Complex OSA Patient Peter Allen, BSRC, RST, RPSGT RRT-NPS-SDS Conflicts of Interest Philips Respironics ResMed Corp Fisher & Paykel DeVilbiss MVAP Natus NovaSom Watermark Content Co-Morbid disease state descriptions and the workflow of those disease states as they pass through the sleep disorders center. COPD Diabetes Morbid Obesity Cardiovascular Stroke Gastroesophageal Reflux/Gerd Metabolic Syndrome Intake, Clinical and Marketing Aspects Learning Objectives 1. Attendee will have a better understanding of the underlying physiology of the co-morbid OSA patient and various aspects of overlap syndrome between disease states. 2. Attendee will be better able to plan and cope with the complex patients in their sleep labs. 3. Attendee will learn to grow clinically while realizing the financial opportunity that these patients represent to their sleep centers. Attendees Night Technologists EEG Background Respiratory Background Home Care DME Home Sleep Testing Lab Managers Lab Owners Hospital Administrators Nursing Physician Assistants Co-Morbid Condition off Your Wing Introduction Since 1970 when Stanford opened the first sleep center and Dr. Guilleminault later described Obstructive Sleep Apnea(OSA), many studies have been conducted regarding associated disease states. Introduction Cont’d Many studies have linked OSA to co-morbid disease states and conditions such as: Cardiovascular and Pulmonary Disease Congestive Heart Failure – 76% A-Fib, - 49% Diabetes – 48% Obesity - 77% Stroke Spinal Cord Injury Reflux/Gerd End Stage Renal – 10 times Greater than General Population Headaches, COPD, Cancer, Metabolic Syndrome Medicare Readmissions Policy Many Co-Morbid disease states that are associated with OSA are being targeted by Medicare as criteria, for financial penalties to Medical Centers where readmissions occurs, within 30 days of discharge. This puts a spotlight on Diagnosis and Treatment of OSA and its associated co-morbid disease states as an integral part of a medical centers financial integrity plan. COPD Chronic Obstructive Pulmonary Disease Two Components Chronic Bronchitis – Productive cough, three months of the year, two or more successive years. Emphysema - Abnormal enlargement of the airspaces in the lungs with destruction to the cell walls. Primarily caused by cigarette smoking. COPD Medications Oxygen – Physician’s Orders Theophylline Ipratropium bromide Advair’ Symbicort Daliresp Theophylline Atrovert Serevent Salmeterol Formeterol Proventol/Ventolin/Abuterol - Nebulizers COPD Referral Sources Pulmonologists Hospitalists Internal Family Internal Medicine Oncologists COPD Intake Concerns Oxygen ?

COPD and the Record CO2 – 35 Normal>>>50+ Low Spo2 – 90% to 97%>>>>88% or less Hypoventilation Centrals During Titration Supplemental Oxygen as needed PVCs, PACs, Uni and Multi-Focal, V-Tach High Heart Rates A-Fib High COPD OSA “Overlap Syndrome” 1. Impaired Lungs plus OSA 2. COPD and OSA jointly contribute 3. More nocturnal desaturations 4. Reduction in respiratory drive-HV 5. Chest wall hyperinflation causes muscle fatigue in these patients. 6. COPD has systemic consequences 7. CO2 High(Retainers), Spo2 Low Overlap Syndrome Conclusions Overlap syndrome increases risk of death and hospitalization due to COPD. PAP treatment with or without oxygen is associated with better patient outcomes along with decreased hospitalizations. Less readmissions for these patients Diabetes Impairment of the body’s ability to use blood sugar for energy. Type 1- Insulin producing Beta cells in pancreas destroyed.

Systemic rather than local disorder 2. OSA & Metabolic = Syndrome Z 3. Causal Relationship Probable 4. Repetitive Hypoxia 5. Adipokines and Inflamatory Cytokines 6. Estimated 24% of US Population Metabolic Syndrome Three of the following five variables: Hypertension resistance – Type 2 Low high-density lipoprotein cholesterol Elevated serum triglyceride Abdominal Obesity-Visceral Fat Insulin Metabolic Syndrome Multiple studies have shown that association between OSA plus Metabolic Syndrome increases as severity of the patient’s OSA increases. PAP has been shown to improve high blood pressure but not insulin resistance or lipid profiles. Coughlin et al. Metabolic Syndrome Studies are showing that OSA and Metabolic Syndrome are not separate comorbidities but actually linked to each other very closely. Metabolic Syndrome The Sleep Heart Health Study found a significant association between the respiratory disturbance index and waist to hip ratio, hypertension, and hypercholesterolemia in men, and low HDL-C, and hypertriglyceridemia in women. A matched control study found that OSA was associated with insulin resistance, total cholesterol, HDL-C and Leptin. A Japanese study showed that OSA may promote metabolic dysfunction and fat maldistribution. Metabolic Syndrome Linkage between OSA and Diabetes is very well documented and appears to play a role in Metabolic Syndrome. Prevalence of OSA in obese Type 2 Diabetic patients with moderate to obstructive severe sleep apnea has been reported as high as 70%. Metabolic Syndrome Hypothalmic-pituitary-Adrenal(HPA) Axis Cortisol – Hormone/Steroid is released – Adrenal Gland Cortisol secretion was increased by sleep apnea Study shows that obese men with OSA have abnormally higher sympathetic nervous system activity and HPA. Autonomic(ANS), Sympathetic(SNS), Parasympathetic(PNS) OSA has inflamatory cascade component, although linkage to OSA is still unclear. Repetitive hypoxia and reoxygenation lead to oxidative stress Oxidative stress appears to be a consequence of metabolic syndrome and visceral obesity. Oxidative stress activates an inflammatory response. Metabolic Syndrome Inflammatory responses activate Cytokines. Inflammation, metabolic syndrome ties in with atherosclerosis. Biomarkers are used by researchers to track the bodies inflammatory responses and associate them with OSA. Obesity is the common factor that connects OSA TO Metabolic syndrome. Monocytes and Macrophages abound and increase through what is known as the “Cascade”. Monocytes>>Macrophages eat/destroy Adipokines-Fat derived Cytokines-One is Leptin. Leptin plays a role in appetite and energy. Ghrelin-Hormone that also regulates appetite. High levels after weight loss. CPAP reduces Monocyte Responds Macrophage Engulphs Pathogen Exploding Macrophages Metabolic Syndrome Patients with sleep apnea have reduced Leptin levels. Sleep deprivation unto itself,,, alone,,, contributes to increased levels of Ghrelin, increased appetite, higher glucose levels, insulin resistance, and therefore a higher risk of diabetes. OSA compounds and contributes to most any other disease state a patient has. (Allen, P. et al) Normalization of metbolic parameters often occurs after PAP tx. Metabolic Syndrome Conclusion Metabolic syndrome consists of a systemic and complicated chain of events and components, one of which can be the presence of Obstructive Sleep Apnea. Research is showing that Sleep Disorder Medicine will be playing a major role in the diagnosis and treatment of patients with Metabolic Syndrome or Syndrome Z.
