Abstract

Alpha-1 Antitrypsin deficiency (AATD) is a genetic condition that can lead to Chronic Obstructive Pulmonary Disease. The burden of psychological disease, its impact and contributing factors in patients with AATD are largely unknown. This study determined the prevalence of depression and anxiety in AATD and its clinical impact. All subjects with PiZZ/PiZnull (n = 635) and PiSZ (n = 111) genotypes within the AATD registry who had sufficient data to calculate pulmonary physiological and health status (HS) decline were grouped as those with or without a diagnosis of depression and/or anxiety. Univariate and multivariate analyses were performed on physiological, demographic and HS parameters. Depression and/or anxiety was present in 16.4% overall in both PiSZ and PiZZ/PiZnull cohorts and was associated with lower baseline pulmonary function and worse HS. In the multivariable analysis of the PiZZ/PiZnull cohort, a greater average decline in FEV1% predicted was observed in those with depression and/or anxiety than those without (–1.53 SD ± 2.26 per year, −0.99 ± 1.79, respectively; p = 0.03) but there was no difference in HS decline (p = 0.33). No differences were seen in the PiSZ cohort. Dyspnoea (mMRC score) was generally worse in those with depression and/or anxiety than those without. Comorbidity burden did not differ between those with or without depression and/or anxiety. Disease severity and progression may be contributing to the prevalence of psychological factors in PiZZ/PiZnull patients. Patients who are declining rapidly should be actively monitored for psychological co-morbidity and treated by cognitive or pharmacological means.
