Of 200,000 Swedish infants screened for alpha 1-antitrypsin deficiency (alpha 1 ATD), 184 (127 PiZ, 2 PiZ-, 54 PiSZ, and 1 PiS-) children have been followed prospectively, of whom 1 PiSZ and 5 PiZ children died in early childhood. We now report clinical and biochemical signs of liver disease in adolescence and the prognosis of neonatal liver disease up to the age of 18 years. The alpha 1 ATD subjects were offered a clinical checkup and liver tests at 16 and 18 years of age, 150 of 178 alpha 1ATD subjects undergoing checkups at age 16 and 166 at age 18. Liver tests were performed in 121 adolescents at both the 16- and 18-year checkups. None of the PiZ and PiSZ subjects checked at the age of 16 and 18 years had any clinical signs of liver disease. Abnormalities of serum alanine aminotransferase (S-ALAT) or gamma-glutamyl transferase (S-GT) were found at the 16-year checkup (all PiZ and PiSZ subjects tested included) in 17% of PiZ and 8% of PiSZ adolescents, and at the age of 18 years in 12% of PiZ and 15% of PiSZ subjects. In only two cases were both S-ALAT and S-GT concentrations abnormal at both the 16-year and 18-year follow-ups. Serum procollagen III peptide concentrations were normal in all those with abnormal liver test results. Of 127 PiZ subjects, 22 had manifested clinical signs of liver disease in infancy. Of these 22, two died early in life of cirrhosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Objective: The present study aimed to investigate the adverse effects of the antithyroid drugs propylthiouracil (PTU) and methimazole (MMI)/carbimazole (CMZ) in treating hyperthyroidism. Methods: Qualitative analysis was performed for studies identified in a literature search up to April 20, 2019, and 30 studies were selected for meta-analysis. The study designs included case-control, randomized controlled, and retrospective cohort. Patients were in four age groups: childhood, gestating mothers, older adults, and other ages, and all were receiving PTU or MMI/CMZ. Adverse reactions to MMI/CMZ and PTU were evaluated and compared. Results: Odds of liver function injury were higher in the PTU group than in the MMI/CMZ group (odds ratio [OR], 2.40; 95% confidence interval [CI], 1.16 to 4.96; P = .02). Odds of elevated transaminase were much higher in the PTU group than in the MMI/CMZ group (OR, 3.96; 95% CI, 2.49 to 6.28; P<.00001). No significant between-group differences were found in odds of elevated bilirubin, agranulocytosis, rash, or urticaria; incidence of other adverse events; or in children. Odds of birth defects during the first trimester of pregnancy were higher in the MMI/CMZ group than in the PTU group (OR, 1.29; 95% CI, 1.09 to 1.53; P = .003). Conclusion: The impact of PTU on liver injury and transaminase levels is greater than that of MMI/CMZ, but no significant between-group differences are found in the drugs' effects on bilirubin, agranulocytosis and rash, urticaria, or in children. In treating pregnancy-related hyperthyroidism, PTU should be used in the first trimester and MMI reserved for use in late pregnancy.
