A Phase II, multicenter clinical trial of bendamustine plus rituximab (BR) regimen was conducted in previously untreated patients with high-tumor-burden indolent B-cell non-Hodgkin lymphoma (B-NHL) and previously untreated elderly patients with mantle cell lymphoma (MCL) in Japan. Bendamustine 90 mg/m2/day on days 1 and 2, as well as rituximab 375 mg/m2 on day 1 were administered intravenously up to six cycles. The primary endpoint was the complete response (CR) rate as assessed by the International Workshop Response Criteria (1999). ⋯ Major grade 3/4 toxicities were hematologic and included lymphopenia (97%), CD4 lymphopenia (91%), neutropenia (86%), and leukopenia (83%). No treatment-related death was found. The BR regimen showed high efficacy as evidenced by the expected CR rate and durable response, as well as an acceptable safety profile for the study populations.

Dysfibrinogenemia is characterized by blood coagulation dysfunction induced by an abnormal molecular structure of fibrinogen. Here, we describe a new case. A 32-year-old female was suspected of having dysfibrinogenemia during routine laboratory screening, based on her decreased functional fibrinogen level, normal fibrinogen antigen level, and prolonged thrombin time. ⋯ Sodium dodecyl sulfate polyacrylamide gel electrophoresis and western blot showed no difference. We report a new case with a mutation in the fibrinopeptide A region, AαGly13Arg. These results indicated that the functional abnormalities were related to delayed and defective fibrinopeptide A cleavage and likely impaired thrombin binding.
