PROLASTIN-C Liquid for Alpha1-Antitrypsin Deficiency Stone P, Morris T III, Franzblau C, Snider G. Preliminary evidence that augmentation therapy diminishes degradation of cross-linked elastin in alpha-1-antitrypsin-deficient humans. There are limited data on economic aspects of the genetic variant of chronic obstructive pulmonary disease (COPD) in the context of the more prevalent form of COPD. Molecular-based testing is highly accurate, but as in any laboratory test, rare diagnostic errors may occur. The test is also done to check for abnormal forms of AAT. AAT is a protein that is made in the liver. Edgar RG, Patel M, Bayliss S, Crossley D, Sapey E, Turner AM. Chest J. Background: For individuals with emphysema because of severe alpha(1)-antitrypsin deficiency, specific therapy called IV augmentation therapy has been available since 1989. Insurance. However, the annual costs of patients with AATD differed drastically depending on AUG use status and amounted to $127,537 among users and $15,874 among nonusers (P <.001). Am J Respir Crit Care Med.

PMC European Organisation for Rare Diseases (EURORDIS). See this image and copyright information in PMC. 2009;6(3):17784. Nevertheless, even without underlying AATD, COPD has been described as a disease with a high and increasing economic burden over time and substantial incremental costs as compared to patients without COPD [28, 40].

Why the Test is Performed. A generalized linear model was used to estimate total pre- and post-index (initial COPD diagnosis) costs from a third-party payer's perspective (2018 USD) controlling for confounders. Stockley RA, Bayley DL, Unsal I, Dowson LJ. A generalized linear model was used to estimate total pre- and post-index (initial COPD diagnosis) costs from a third-party payers perspective (2018 USD) controlling for confounders. However, the AATD-associated COPD patients are routinely excluded from clinical trials of COPD medications [27]. Patients with AATD-associated COPD were statistically different in terms of all baseline covariates except for mean age and Charlson Comorbidity Index (Table 1). Print 2022 Mar 31. Alpha 1-Antitrypsin (AAT), IHC with Interpretation: 19123X: Alpha 1-Antitrypsin (AAT), IHC without Interpretation: 19283X: Augustine EF, Adams HR, Mink JW. While AATD-associated COPD patients are usually younger as compared to non-AATD-associated COPD, the observed age difference in this study was reduced due to matching. Rare diseases: Understanding this public health priority. The exact matching algorithm without replacement included the following variables: gender, Quans Charlson Comorbidity Score, census region, race/ethnicity, age at diagnosis (+/1year), year of COPD diagnosis and oxygen use (Yes/No; within the first 12months after the index date) as a proxy for COPD severity. view test results, and more. Phenotyping is desirable on patients with low values and on all patients being worked up for AAT-deficient liver disease. It's the "off switch" for an enzyme called neutrophil elastase. C.

Respir Res. The researchers said a major limitation of this study is the lack of data regarding smoking status and phenotype information. Another limitation stems from the fact that only commercially insured patients of 1 large health plan were included; patients receiving healthcare services through public or other payers were not represented.

The Clinical Practice Guidelines published in theJournal of the COPD Foundationin July 2016,based on the latest evidence and six years of work, offer the followingrecommendations for Alpha-1 testing: Anyone can ask their doctor to test them for Alpha-1 or they may choose to be tested confidentially through the Foundations Alpha-1 Coded Testing (ACT) study.

The higher use of ER visits and prescription medications may be mitigated if AATD-associated COPD patients enrolled in a disease management program [48, 49]. Overall, out of 1018 AATD-associated COPD patients who met inclusion criteria, 953 cases had up to 10 unique matched controls by randomly matching with 7928 patients non-AATD-associated COPD patients. To rule out other variants, further testing of symptomatic individuals heterozygous for one variant (S or Z) or with negative results may include phenotyping (PI typing), AAT level testing, and/or expanded genotyping. This finding is important to patients and payers, as a timely diagnosis of AATD status would facilitate more personalized care, through a reduction in the number of unscheduled physician visits [48]. 8600 Rockville Pike Every week, The American Journal of Managed Care recaps the top managed care news of the week, and you can now listen to it on our podcast, Managed Care Cast. Costs and health-related quality of life in Alpha-1-Antitrypsin Deficient COPD patients. 2012;31(25):304150. Two variants are analyzed: c.1096 G>A (p. Glu366Lys), commonly referred to as the Z allele or PI*Z c.863 A>T (p.Glu288Val), commonly referred to as the S allele or PI*S. DNA analysis of the S and Z alleles in the SERPINA1 gene (NM_000295.4) is performed by multiplex allele-specific PCR amplification followed by gel electrophoresis. 1995;62(2):769. Patients with more severe forms of COPD might incur higher costs both before and after COPD diagnosis. Clinical trials in rare disease: challenges and opportunities. New ICD-10 version of the charlson comorbidity index predicted in-hospital mortality. Alpha-1 antitrypsin or 1-antitrypsin ( A1AT, 1AT, A1A, or AAT) is a protein belonging to the serpin superfamily. Molecular-based testing is highly accurate, but as in any laboratory test, rare diagnostic errors may occur.

Institutional Review Board (IRB) approval was obtained from the IRB of the University of Maryland, Baltimore, on July 27, 2016 (HP-00068329). In addition, factors prompting the initial COPD diagnosis claim among patients affected and unaffected by AATD might differ in an unknown manner. Pediatr Pulmonol. After the index date, the cases incurred higher OP costs (cost ratio: 1.490; 95% CI: 1.0552.103), higher OTH costs (cost ratio: 11.834; 95% CI: 7.83417.875) and RX costs (cost ratio: 1.372; 95% CI: 1.0871.731; Table 4), resulting in an additional $5782 (95% CI: $3982 - $7582) and $1974 (95% CI: $141 - $3447) in OTH and RX expenditures, respectively.

Chest J. Where prior cost studies conducted in the United States merely estimated the total cost of AATD care, this study delineated the cost difference between treating AATD- associated COPD from the garden variety form of COPD [28].

The retrospective analysis of the direct medical costs of AATD used data from the OptumLabs Data Warehouse (OLDW), which includes de-identified claims data for privately insured and Medicare Advantage enrollees in a private US health plan. The OLDW is a comprehensive, longitudinal real-world data asset with de-identified lives across claims and clinical information. Patients over 65 for whom Medicare was the primary payer were excluded from the analysis. This could motivate payers to invest in AATD-COPD disease detection and management endeavors.
