WHO 1996 – Recommendations for AATD screening and therapy*
In 1996, the WHO adressed the issue of AAT deficiency. The recommendations included the following:
Quantitative AAT screening for all patients with COPD
Quantitative AAT screening for all patients with asthma
All identified AAT deficient patients should receive:
• Immunization against influenza and pneumococal infections
• Appropriate treatment of respiratory infections
• Genetic counseling
AAT augmentation therapy in case of AATD associated emphysema
