“…51 As a result, only 2-3% of Pi*ZZ children develop end-stage liver disease that may require liver transplantation, and at age 18, only 12% of them display elevated ALT or GGT. 49,51,53 Interestingly, increased CHOP, which upregulates SERPINA1 transcription, was detected in diseased livers of Pi*ZZ children but not in adults, suggesting that CHOP plays an important role in hepatic disease by increasing the burden of proteotoxic Z-AAT, particularly in the pediatric population. 30 Notably, a clinically significant pediatric liver disease in less severe genotypes, such as Pi*MZ or Pi*SZ, is exceedingly rare and might be at least in part caused by additional comorbidities, such as cystic fibrosis.…”

“…Alpha-1-antitrypsin deficiency (AATD) is a genetic disorder predominantly characterised by liver and lung afflictions. While metabolic liver disease shows a peak prevalence in early childhood and after the age of 40, lung emphysema is not seen in children with AATD [ 1 , 2 , 3 ]. The disease is caused by a mutation in the SERPINA1 gene inherited in an autosomal recessive pattern with a co-dominant expression of alleles.…”

“…Bis zu 2 % aller juvenilen Patienten mit schwerem AATM (Genotyp Pi*ZZ, Häufigkeit 1:3000) entwickeln ein Leberversagen und benötigen eine Lebertransplantation. Im Erwachsenenalter weisen 20-35 % der Pi*ZZ-Verlauf der Alpha-1-Antitrypsinmangel-assoziierten Leberschädigung bei pädiatrischen und erwachsenen Individuen mit schwerem Pi*ZZ-Genotyp sowie Risikofaktoren, die zur Organschädigung bei Erwachsenen prädisponieren (Daten aus[2,3,12,14]). Betroffenen eine relevante Leberfibrose auf.…”
