PURPOSE: This study aimed to identify if individuals with mild to severe alpha-1 antitrypsin deficiency (AATD) are at higher risk for developing obstructive sleep apnea (OSA) than the general population. METHODS: A seven-question sleep apnea risk assessment questionnaire, STOP-BAG, was applied to 2338 participant responses from the Alpha-1 Coded Testing Study (ACT) and 4638 participant responses from the Kentucky Behavioral Risk Factor Survey (KyBRFS). Propensity scores were generated from a logistic regression model using continuous variables of age and body mass index (BMI). STOP-BAG scores were analyzed using chi-square analysis on this matched cohort to assess OSA risk in AATD. RESULTS: Self-reported OSA was higher in the KyBRFS cohort (14.5%) than in individuals with mild or severe AATD (11.2%) (p = 0.012). However, a higher percentage of the AATD cohort met clinically meaningful thresholds for STOP-BAG scores ≥ 5 (22.7%) than the KyBRFS cohort (13.0%) (p = 0.001). These differences persisted despite 1:1 propensity score matching on age and BMI to account for differences in baseline characteristics. No statistically significant difference in OSA risk between AATD genotypes was found. CONCLUSION: AATD appears to have higher risk for OSA than the general population. The 11.2% prevalence of diagnosed OSA in the AATD population is much lower than symptom scores would predict. Further studies are needed to validate the possibility that elastin loss is involved in OSA pathogenesis.

Familial hypercholesterolemia (FH) is a genetic disorder of cholesterol metabolism that affects an estimated 1/250 persons in the United States and abroad. FH is hallmarked by high low-density lipoprotein (LDL) cholesterol and an increased risk of premature atherosclerotic cardiovascular disease. This review summarizes recent global evidence showing the utility of FH genetic testing across diverse populations. Clinical and other qualitative outcomes following FH genetic testing were improved FH diagnosis, treatment initiation or continued treatment, treatment modification, improved total or LDL cholesterol levels, education on lifestyle management, and genetic counseling. This summary of evidence should be considered by those seeking overall evidence and knowledge gaps on the utility of FH genetic testing from a global perspective and for certain ethnic and age populations. These findings can be used to inform insurance policies and coverage decisions for FH genetic testing, policy recommendations to reduce the clinical and public health burden of FH, clinical practice and guidelines to improve the management of FH populations, and ongoing research involving FH genetic testing. We conclude that further investigations are needed to examine: (1) non-clinical outcomes following FH genetic testing; (2) patient-reported outcomes following FH genetic testing to convey patient experiences, values, and goals; and (3) clinical outcomes following FH genetic testing in non-Caucasian and pediatric populations in the United States and abroad.
