В статье рассматриваются новые классификационные критерии IgG4-связанного заболевания Европейской антиревматической лиги (EULAR)/Американской коллегии ревматологов (ACR) (2019), их основные отличия от универсальных диагностических критериев IgG4-СЗ (Umehera, 2011) и даны комментарии по их применению. 

This paper considers the new 2019 American College of Rheumatology/European League Against Rheumatism classification criteria for IgG4-related disease, discusses essential differences with IgG4-RD comprehensive diagnostic criteria (Umehara H., 2011) and comments their potential use in clinical practice.
