چکیده

Dr Gyger and colleagues, in reply to our work on granulocyte colony-stimulating factor (G-CSF) bone marrow (BM) purging, have pointed out three aspects of the problem: the possible negative balance of marrow cells after short-term G-CSF administration, the need for at least two cytokines for priming BM stem cells (BMSC), and the probable contamination of BM harvest. Overall, we agree on each of these three points and we would like to stress that the misinterpretation of the term ‘‘priming’’ could be the origin of the observations made by Gyger et al. In fact this term was already used in previous reports1-3 on the same subject showing early expansion of CD341 BMSC and their mobilization. We agree that the term should be used only to mean ‘‘activation’’ of SC and not mobilization. To this purpose we have used the term priming to differentiate it from peripheral blood (PB) mobilization. On the other hand, our data overlap those of Dicke et al,4 where the term ‘‘activation’’ was used with the same meaning of our ‘‘priming.’’ As far as PB contamination, we have stressed this point in the discussion and confirm that the purpose of our study was essentially clinical: in other words, we wanted to show that short-term G-CSF can increase the BMSC, allowing for a positive engraftment compared with steady-state BM. The availability of an alternative source of SC with rapid engraftment may find clinical application in the pediatric and the allogeneic settings.

Glucocorticoid-Responsive Cold Agglutinin Disease in a Patient with Rheumatoid Arthritis

A 57-year-old man with rheumatoid arthritis developed severe anemia during treatment with adalimumab plus methotrexate. Cold agglutinin disease was diagnosed because haptoglobin was undetectable, cold agglutinin was positive (1 : 2048), and the direct Coombs test was positive (only to complement). Although the cold agglutinin titer was normalized (1 : 64) after treatment with prednisolone (0.7 ...

Cold agglutinin disease associated with mycoplasma infection in an individual with type 2 diabetes: An atypical case

Cold Agglutinin Disease is a hemolytic anemia associated with cold reactive autoantibodies. Although the acute form of cold agglutinin disease can be attributed to autoimmune or infectious diseases and lymphoproliferative diseases, it has,to the best of our knowledge, so far,never been reported as secondary to Mycoplasma pneumonia in a type 2 diabetic individual. In this paper, we report a case...

Eculizumab as a bridge to immunosuppressive therapy in severe cold agglutinin disease of anti-Pr specificity

Severe cold agglutinin disease with hemodynamic compromise requires rapid stabilization of the autoimmune hemolytic anemia as a bridge to the immunosuppressive effect of rituximab. Herein, we describe eculizumab treatment of severe complement-mediated hemolysis in a patient whose hemodynamic status deteriorated in spite of supportive blood transfusions and therapeutic plasma exchange.
