E. Therapeutic response The primary end point of one randomized, placebo-controUed trial was whether the patient required one or more platelet transfusions in the subsequent chemotherapy cycle. More patients avoided platelet transfusion in the Neumega arm (28%) than in the placebo arm (7%). 

Neutropenia is a common adverse effect of the cytotoxic drugs used to treat cancer and increases the risk of serious infection in patients receiving chemotherapy. Unlike the treatment of anemia and thrombocytopenia, transfusion of neutropenic patients with granulocytes collected from donors is performed rarely and with limited success. The introduction of G-CSF in 1991 represented a milestone in the treatment of chemotherapy-induced neutropenia. This growth factor dramatically accelerates the rate of neutrophil recovery after dose-intensive myelosuppressive chemotherapy (Figure 33-5). It reduces the duration of neutropenia and usually raises the nadir count, the lowest neutrophil count seen following a cycle of chemotherapy. 

Interleukin-11 is the first growth factor to gain FDA approval for treatment of thrombocytopenia. It is approved for the secondary prevention of thrombocytopenia in patients receiving cytotoxic chemotherapy for treatment of nonmyeloid cancers. Clinical trials show that it reduces the number of platelet transfusions required by patients who experienced severe thrombocytopenia after a previous cycle of chemotherapy. Although IL-11 has broad stimulatory effects on hematopoietic cell lineages in vitro, it does not appear to have significant effects on the leukopenia or neutropenia caused by myelosuppressive chemotherapy. Interleukin-11 is given by subcutaneous injection at a dose of 50 g/kg/d. It is started 6-24 hours after completion of chemotherapy and continued for 14-21 days or until the platelet count passes the nadir and rises to > 50,000 cells/ L. 

S-FFF has been applied for the separation of living cells such as human, sheep, rabbit, and horse blood cells or HeLa cells [12,296,420,440-444] which, furthermore, could give insight into the growth and cell cycle distribution of cells in cultivation broths [444] or an estimation of the bacterial biomass in natural waters [445]. Blood components have been separated in the same apparatus [446]. Car-dot, Martin, and co-workers have shown that abnormal blood cells (from anemia or transfusions) can be distinguished from healthy erythrocytes in Gr-FFF [413,415]. In such channels, a prevalent parasite can be isolated from blood, suggesting a possibility for rapid diagnosis [414].

Carboplatin and cyclophosphamide are indicated in the treatment of advanced ovarian carcinoma. Cisplatin and carboplatin produce predominantly interstrand DNA crosslinks rather than DNA-protein cross-links, and the effect is cell-cycle nonspecific. Carboplatin is not bound to plasma proteins, whereas platinum from carboplatin becomes bound to plasma protein and is eliminated slowly with a half-life of 5 days. The major route of elimination of carboplatin is the kidneys, and its doses should be reduced in renal impairment. Furthermore, the coadministration of aminoglycosides increases the chance of nephrotoxicity. Carboplatin causes anemia, neutropenia, leukopenia, and thrombocytopenia requiring transfusions. Cisplatin and, to a lesser extent, carboplatin cause emesis, which requires treatment with antiemetic agents. Alopecia, pain, and asthenia do occur (see also Figure 15). 

The 2007 Tour de France was marred by several scandals, including the expulsion of Kazakstan cycling star Alexandre Vinokourov, who was accused of having taken autologous blood transfusions to boost his red cell count. 

Fig. 2 illustrates the effect of CdA in vitro on NAD levels in CLL cells from the responders compared to non-responders. It is evident that the NAD fall is not consistent among patients within the responding group. Fig. 3 illustrates the time-course of response in a patient treated because of refractory anemia. Although he was initially dependent upon frequent transfusions, this patient s hemoglobin level was well maintained following three cycles of CdA, without further transfusion support. 

Fig. 3. Hematologic response to CdA therapy in a patient with CLL. CdA 0.1 (mg/kg per day) was administered by continuous intravenous infusion for 7 days at the times indicated (shaded). Prior to the third cycle of CdA, the patient required frequent transfusions for refractory anemia.

Endocrine Excessive menstrual bleeding occurred in two women after adalimumab administration. Bleeding began 6 months and 4 months after therapy in a 41- and 37-year-old woman, respectively. Bleeding ceased 3 days after transfusion and norethisterone administration in the former case and 3 days after estradiol in the latter case. A normal menstrual cycle resumed for both women [78 ]. 

The discovery of blood transfusion and the beginning of an industrial life cycle. Blood transfusions became possible after 1900, following the discovery of the ABO system and blood group compatibility by Karl Landsteiner (innovation stage). The period from 1910 to 1930 saw the first steps towards optimisation progress was concentrated on the conditions for large-scale commercialisation, the organisation of the blood collection network, blood banks and the development of clinical applications.
