Abstract
This study assessed the grade of bone marrow (BM) fibrosis and its association with a seromarker for collagen-III formation and fibrosis-related cytokines in 25 immune thrombocytopenia (ITP) patients treated with thrombopoietin receptor agonists (Tpo-RA) who had at least one BM biopsy. Assessment of 8 pre- and on-treatment BM biopsies revealed statistically significant increases in reticulin. Reticulin in biopsies performed after a median of 1·4years of treatment was graded: MF-0 in 3 (12%), MF-1 in 19 (76%), MF-2 in 2 (8%) and MF-3 in 1 (4%). No cytogenetic or flow-cytometric abnormalities were detected. Median pretreatment Procollagen III N-propeptide (PIIINP) (6·6μg/l) was significantly higher than on-treatment levels (5·6μg/l); both were higher than controls (3·4μg/l; P
