Despite some considerable progress in the therapy for chronic lymphocytic leukaemia (CLL) owing to fludarabine-based regimens and rituximab, no curative treatment is available so far. We conducted an explorative phase II study in patients with CLL, prolymphocytic leukaemia (PLL) and leukaemic lymphoplasmacytic lymphoma (LL) with the combination of fludarabine, epirubicin and rituximab (FER) to improve the complete remission (CR) rate and progression-free survival (PFS). Fludarabine 25 mg/m(2) was administered i.v. on days 1-5 and epirubicin 25 mg/m(2) i.v. on days 4 and 5, and rituximab was added at a dose of 375 mg/m(2) i.v. day 1 in the first cycle and at a dose of 500 mg/m(2) in all consecutive cycles. ⋯ After a median follow-up period of 34 months (range: 8-84 months), median PFS was 61 months and overall survival was yet not reached. All patients with PLL and LL achieved CR. The data support the high efficacy of the combination of rituximab with chemotherapy (FE) and are suggestive of possible benefit with rituximab maintenance therapy for PFS and DFS.

Of patients with severe aortic stenosis, 15-25% present with bleeding episodes possibly attributable to acquired von Willebrand syndrome (AVWS). AVWS associated with mitral valve prosthesis leakage has not been reported. ⋯ Acquired VWF qualitative alterations in mitral valve prosthesis leakage may be associated with or contribute to bleeding diathesis. AVWS should be taken into consideration in patients with mitral valve prosthesis leakage with bleeding diathesis not explained by excessive oral anticoagulation.
