Intensive smoking diminishes the differences in quality of life and exacerbation frequency between the alpha-1-antitrypsin deficiency genotypes PiZZ and PiSZ
چکیده انگلیسی


- PiSZ individuals represent only a minority in the German AATD registry.
- PiSZ subjects smoked significantly more than PiZZ individuals.
- Moderate (ex-) smoking PiSZ subjects have less exacerbations than PiZZ individuals.
- Moderate (ex-) smoking PiSZ subjects have better SGRQ than PiZZ individuals.
- Significant differences between PiZZ and PiSZ diminish with intensive smoking.

BackgroundAlpha-1-antitrypsin deficiency (AATD) is a rare genetic disorder that is associated with low levels of circulating alpha-1-antitrypsin in serum. In comparison to the genotype PiZZ, PiSZ usually leads to lower risk of emphysema, better lung function and better survival.The aim of this study was to analyze the relationship between cigarette smoking (packyears) and the AATD genotypes (PiZZ and PiSZ) concerning quality of life (SGRQ), transfer factor of the lung for carbon monoxide (TLCO), forced expiratory volume in one second (FEV1) and exacerbation rate.MethodsWe compared PiZZ and PiSZ individuals from the German registry for individuals with AATD (AATDR) in univariate analysis and multivariate linear regression models. All subjects were stratified into three groups according to their cumulative nicotine consumption (0 py; 0 < py < 30; ≥30 py).Results868 PiZZ individuals (mean age 52.6 ± 12.8 years (43.5% female)) and 114 PiSZ individuals (mean age 50.3 ± 17.4 years (46.5% female)) were compared.In contrast to never- and intensive (ex-) smokers, moderate (ex-) smoking PiSZ individuals had a significantly better SGRQ total score (B = −8.148; p = 0.020) and less exacerbations (B = −0.354; p = 0.037) than individuals with PiZZ in multivariate analysis.ConclusionsThe differences in quality of life and exacerbation frequency between PiZZ and PiSZ individuals diminish by intensive (ex-) smoking.
