BACKGROUND: Evans syndrome (ES) is a rare immune-mediated disorder involving two or more cytopenias, including immune thrombocytopenia (ITP), autoimmune hemolytic anemia, and/or immune neutropenia. ES may occur secondary to another condition or be idiopathic. While consensus recommendations exist for adults, there is no standardized diagnostic approach for pediatric Evans syndrome (pES). This study aimed to describe typical diagnostic evaluations conducted by clinicians caring for pES patients.
METHODS: A cross-sectional survey of the Pediatric ITP Consortium of North America (ICON) assessed typical diagnostic workup for pES, the influence of clinical features on testing, evaluation for underlying disorders, including immune defects and autoimmune disease, subspecialty involvement, and genetic testing practices.
RESULTS: Sixty percent (28/47) of respondents reported performing the same evaluation for all pES patients. There was no consensus on specific diagnostic tests. Providers consistently evaluated for autoimmune conditions, but varied in testing for inborn errors of immunity (IEI). Rheumatology and immunology were most often consulted. Most respondents (85%, n = 40) obtained genetic testing through commercial laboratories, frequently encountering insurance-related barriers.
CONCLUSIONS: Even among experts, diagnostic approaches to pES vary widely. Standardized frameworks are needed to guide comprehensive evaluation for this complex disorder.
