In the absence of a donor alternative a stem cell transplantation consisting of two cord blood components originating from the haploidentical brother was performed in a 2-year-old girl with c-ALL, early CNS relapse and 7% of blast cells in the BM 14 days before transplantation. Because of various ongoing infectious complications at that time, 1/8 of the immunogenetically acceptable sibling cord blood was ex vivo expanded 10 days before the transplantation date. The total CB consisting of 1.17 x 10(9) NC was cryopreserved in four separate bags. The one containing 1/8 of the total CB with 1.4 x 10(8) NC CliniMACS selected CD34+ cells was expanded in the presence of 100 ng/ml G-CSF, 100 ng/ml TPO and 100 ng/ml flt3-L in 10% autologous CB plasma and X-VIVO 10 medium at day -10 before transplantation. This expanded cell population was sterile and consisted of about 60% granulocytic cells (CD13+, CD15+), about 30% myelomonocytic cells (CD14, HLA-DR+), 5.2% megakaryocytes (CD61+) and 1.2% CD34+ cells. The proportion of T (CD3+), NK cells (CD56+) as well as dendritic cells (CD83+) was below 0.2%. The unseparated CB infused at day 0 and +1 consisted of a total of thawed 4.4 x 10(7) NC/kg BW, 5.8 x 10(4) CFU-GM/kg BW, 1.54 x 10(5) CD34+cells/kg BW and 7. 73 x 10(2) LTC-IC/kg BW. In addition, the 1 x 10(7) NC/kg BW ex vivo expanded cells representing 1.9 x 10(4) CFU-GM/kg BW, 1.13 x 10(5) CD34 cells/kg BW and 4.37 x 10(2) LTC-IC/kg BW, were infused at day +1. At day +2 after transplantation the patient revealed a focal pneumonia on X-ray with generalized sepsis and became catecholamine dependent. From day +4 the patient received 280 microg/m2 G-CSF. At day +5 she developed an erythroderma, which could not be identified as acute GVHD by biopsy. Early engraftment with leukocyte counts at days 8 and 14 were 350 and 700/microl, ANC 310 and 410/microl, respectively. Donor cells determined by chimerism analysis were 97% and 98% in the periphery at this early time. Most importantly, the pneumonia as well as the septicemia subsided within a few days. Notably, as well is the clearly shortened aplastic phase observed after this simultaneous CB cell component transplantation. The patients T cell and NK cell reconstitution could be detected at day +37 with 330 CD3+ cells/microl and 40 CD56+ cells/microl, respectively. The time to reach an absolute platelet count of 20 000 (50 000)/microl was 75 (103) days. The disease-free survival now exceeds 1 year in complete remission without chronic GVHD or any other health problems. These data show that the applicability of ex vivo expanded committed progenitors and LTC-IC, even in high risk leukemia at the time of transplantation, is feasible and can provide sufficient myeloid progenitors resulting in rapid engraftment able to clear bacterial pneumonia and sepsis. In addition, accelerated hematopoietic reconstitution apparently served as a well functioning platform for definitive graft-versus-leukemia activity. This transplantation of defined ex vivo generated components presents a feasible and generally applicable approach and may open a promising new avenue for cell therapy in malignant diseases.

It remains difficult to treat severely ill patients, especially those who have sepsis and subsequent multiple organ dysfunction syndrome. We propose the hypothesis that the pathophysiology in the sequential sepsis and multiple organ dysfunction syndrome may be strongly related to the imbalance between inflammatory cytokines and antiinflammatory cytokines induced for the host defense to active neutrophils and endothelial cells. Thus we attempted to develop cytokine modulation therapy to normalize the cytokine balance in the host defense system. In this review, we elucidate the relationship between cytokine imbalance and SIRS/CARS in patients with severe burn injury. Furthermore, we examine the possible usage of G-CSF to amplify neutrophil function, and clarify the reasons why various innovative therapies against sepsis have failed.

A proposed scheme between the possible interactions of pro- and anti-inflammatory cytokines, NO and G-CSF during severe inflammation/infection is presented. Taken together, these data indicate that G-CSF exhibits anti-inflammatory properties which may prove to be beneficial in situations associated with an increased activity of the cellular immune system. Since the suppressive effects of G-CSF on the production of pro-inflammatory mediators like TNF-alpha and nitric oxide are most likely neither cell type nor tissue specific, it is conceivable that NO release induced by pro-inflammatory mediators can be reduced by G-CSF in various organ systems and in different forms of shock. In this context, G-CSF might represent a counterregulatory mechanism directed against a downstream oriented inflammatory response to infection. Therefore, the investigation of G-CSF in the prophylaxis of nonneutropenic infections, sepsis, and other severe inflammatory disorders seems reasonable.

Involvement of neutrophils in the control of blood parasites in malaria has been reported. Both, mononuclear phagocytes and neutrophils are known to be stimulated by cytokines such as TNF-alpha in order to augment the defence potency against the parasites. Previously, it has been shown that serum-G-CSF concentrations are increased in patients with bacterial sepsis. In vitro studies have shown that P. falciparum - infected erythrocytes induce the release of G-CSF by several cells such as endothelial cells and monocytes, however, nothing is known about G-CSF serum concentrations during the clinical course of severe P. falciparum malaria. Thus, it was the aim of the present study to investigate the time course for G-CSF serum concentrations in patients with complicated P. falciparum malaria, and to correlate these values with other mediators of inflammation and hematopoesis. Twenty-six patients suffering from complicated P. falciparum malaria were included in the study, and 20, age and sex matched, healthy volunteers were used as the negative control group. Serum samples for determination of G-CSF were taken on day 0, 7 and 14, and measured by ELISA. We found significantly increased serum concentrations of G-CSF in patients with complicated P. falciparum malaria on day 0, values decreasing to within the normal range by day 7. A significant correlation was found between G-CSF (d0) and procalcitonin, the parasite count, erythropoietin and macrophage inflammatory protein, however no correlation could be shown for the neutrophil count. In conclusion, on the day of hospital admission, elevated serum concentrations of G-CSF were detected in patients with complicated P. falciparum malaria, which might indicate a role of G-CSF in the acute defence mechanism against the parasites.

A family is described in which three members, the propositus, his brother, and son, developed a myelodysplastic syndrome (MDS) at the ages of 52, 35, and 25, respectively. A fourth member, the paternal uncle of the propositus, was diagnosed with chronic lymphocytic leukemia. Two of the three affected Individuals had megaloblastoid marrows with recognizable bone marrow cytogenetic abnormalities and progressive, nonleukemic bone marrow failure. The propositus was unresponsive to G-CSF and eventually died of sepsis. The second affected family member died of bone marrow transplant complications. The third affected family member underwent bone marrow transplantation and is showing signs of graft survival despite minor complications. The affected members of this pedigree appear to represent a continuum in severity of disease and, therefore, pathogenesis. The pattern of inheritance and clinical progression of the disease suggest a genetic defect which may predispose individuals to the development of MDS.

We evaluated the efficacy of combination therapy with sulbactam/cefoperazone (SBT/CPZ) and amikacin sulfate (AMK) in eligible patients with hematological disorders of neutrophil count less than 1,000/microliter. The clinical efficacy rate in 157 evaluated patients was 65.6%. The clinical efficacy rates were related to neutrophil counts and serum albumin levels at the 1 week later. The clinical efficacy rates were 87.1% in patients with neutrophil counts over 500/microliter and 34.8% in patients with serum albumin levels under 3 g/dl after 1 week. G-CSF treatment were not significant but tended to be more effective in patients with sepsis, and the neutrophil counts increased significantly. The group using G-CSF before the antibiotic treatment had a high clinical efficacy rate. It is suggested that G-CSF is effective in patients with neutropenia with the high risk to infection and in those who already have severe infections.

The present study was aimed at defining the antitumour activity of the cisplatin-paclitaxel-topotecan (CPT) weekly administration with G-CSF support in chemo-naive SCLC patients with extensive disease (ED-SCLC). Chemonaive ED-SCLC patients received cisplatin 40 mg/m(2), paclitaxel 85 mg/m(2), and topotecan 2.25 mg/m(2)weekly, with G-CSF (5 microg/kg days 3-5) support, for a maximum of 12 weeks. 37 patients were treated, for a total of 348 cycles delivered. 8 complete responses (22%) and 22 partial responses (59%) were recorded, giving an 81% [95% CI = 65-92%] ORR. At a 13-month (range, 4-26) median follow-up, median progression-free and overall survival were 8 months and 12.5 months, with 1-year and 2-year projected survivals of 55% and 21%, respectively. No toxic deaths occurred. Grade 4 neutropenia and thrombocytopenia occurred in 6 and 3 patients, respectively. Only one case of neutropenic sepsis was recorded, while haemorrhagic thrombocytopenia was never observed. Diarrhoea, paraesthesias and fatigue were the main nonhaematologic toxicities being severe in 6, 2 and 10 patients, respectively. The weekly CPT combination with G-CSF support represents a well tolerated therapeutic approach in chemo-naive ED-SCLC patients. The activity rate seems at least similar to that achievable with the standard front-line approaches.

Pancytopenia is a rare complication of the thionamide therapy reported secondary to aplastic anemia, the bone marrow being invariably hypocellular. We present a case of a 16-year-old female with Graves' disease who presented with massive bone marrow plasmocytosis mimicking multiple myeloma. The patient had already been on methimazole for a month when she was admitted to the Pediatric Unit with the diagnosis of sepsis. CBC revealed pancytopenia. Bone marrow aspirations showed hypocellular-normocellular bone marrow, 98% of plasma cells. At that time, MMI was discontinued and the patient was started on broad-spectrum antibiotics, dexamethasone, and G-CSF. Bone marrow aspiration day +4 still showed hypo-normocellular marrow, with remaining 6% plasma cells. Myeloma screen was negative; ANC >1,000 at day +7, platelets >50,000 at day +24. Twenty-four months after patient's discharge, her clinical condition, CBC, and bone marrow remained normal. To our knowledge this is the first report of pancytopenia due to MMI, where the usual hypoplasia found is replaced by massive plasmocytosis.

Bacterial translocation/Acute radiation syndrome/Endotoxin/G-CSF/OK-432 Acute radiation induces bacterial translocation from the gut, followed by systemic infection and sepsis. In order to reduce the mortality after acute whole body irradiation, it is essential to control bacterial translocation. In this study, we established a bacterial translocation assay as a sensitive method to detect minor mucosal injury by radiation. By utilizing this assay, we evaluated the adverse effects, if any, of hematopoietic reagents on the mucosal integrity in the respiratory and gastro-intestinal tracts. Bacterial translocation to the liver and spleen occurred after whole-body irradiation if the dose exceeded 6 Gy. The administration of G-CSF unexpectedly increased the bacterial translocation in 8 Gy-irradiated mice. The pharmaceutical preparation of low-virulent Streptococcus pyogenes, OK-432, significantly reduced the endotoxin levels in peripheral blood without any reduction of bacterial translocation. A combined treatment with G-CSF and OK-432 decreased bacterial translocation and prevented death. This result indicates that the early administration of G-CSF has an adverse effect on bacterial translocation, and that a combined treatment of G-CSF and OK-432 attenuates the adverse effect of G-CSF and improves the survival rate after acute irradiation.

In this experimental study, consist of 54 Sprague-Dawley rats, we tried to observe the effectiveness of haemopoietic growth factors such as G-CSF and GM-CSF in treatment of sepsis and see if they have any effects on phagocytic activity of macrophages when are administered after establishment of sepsis. In first phase of this study, twenty one rats were randomly divided into three groups of 7 animals each. Cecal ligation and perforation were carried out in each rat and sepsis made up. The Control group received 2 x 0.2 cc %5 dextrose injection subcutaneous (s.c.).. The G-CSF group received 2 x 1 g G-CSF with 0.2 cc %5 dextrose s.c. The GM-CSF received 1 x 2 g GM-CSF with 0.2 cc %5 dextrose s.c. Seventh day survival was considered as criterion in the three groups. In second phase of this study, thirty three rats were randomly divided into three groups of 11 animals each. The same procedures were carried out also in these groups. Leukocyte counts and peripheric spread were analyzed in postoperative 24th and 72th hours, alveolar and peritoneal macrophages were Investigated in postoperative 72nd hour. There was significantly neutrophilic leukocytosis in the G-CSF group according to the control group. Nevertheless, there was no change in the phagocytic activity of alveolar and peritoneal macrophages. GM-CSF brought about positive effect of phagocytic activity of macrophages without change of leucocyte count in the sepsis, but it caused neutrophilic, monocytosis and lymphocytopenia. The seventh day survival rates in control, G-CSF, GM-CSF groups were as; 42.8%, 71.4%, 28.5% respectively. As a result, we saw that G-CSF has no effect on the phagocytic activity of macrophages, while increases the survival by enhancing the count and probably the function of neutrophils. GM-CSF fails to increase survival while effects the phagocytic activities of macrophages positively and enhances the peripheral neutrophil and monosit counts without changing the total number of leukocytes.
