Pie graph representations of CD20+ B-lymphocytes-association with inflammatory dilated cardiomyopathy. (A) The pie chart represents 82 patients (red) with endomyocardial biopsies CD20+ B-lymphocytes infiltrates (>7 cells/mm²) out of 156 inflammatory dilated cardiomyopathy patients. (B) The main pie chart represents 24 endomyocardial biopsies-proven inflammatory dilated cardiomyopathy patients who were treated with prednisolone/azathioprine for 6 months, 16 patients (blue) were responders and eight patients (yellow) were non-responders. The pie-of-pie represents the steroid non-responders of which five patients (dark red) showed high-persistent endomyocardial biopsies CD20+ B-lymphocyte infiltrates (average 20.8 cells/mm²), and three patients (orange) with newly identified low-grade CD20+ B-lymphocytes in the follow-up biopsies (average 12.50 cells/mm²).
