The All Japan TAFRO Syndroe Research Group reported a classification for the severity of TAFRO Syndrome, with initial criteria in 2015 and an update in 2019.
Patient selection: TAFRO syndrome
Parameters:
(1) anasarca (pleural effusion on imaging, ascites on imaging, pitting edema)
(2) thrombocytopenia (platelet count per µL)
(3) fever and/or inflammation (body temperature in °C or serum CRP in mg/dL)
(4) renal insufficiency (GFR)
