Eighty-six patients with infections associated with hematological disorders were treated with sulbactam/cefoperazone (SBT/CPZ) and amikacin (AMK). Among 71 evaluable cases, 30 cases had acute non-lymphocytic leukemia, 3 acute lymphoblastic leukemia, 25 malignant lymphoma, and 7 myelodysplastic syndrome as underlying diseases. Excellent responses were obtained in 33 cases (46.5%) and good responses in 14 cases (19.7%), with an overall efficacy rate of 66.2%. The efficacy rate among cases with suspected sepsis was 72.5%. This treatment was also effective in 69.2% of cases in which neutrophil counts were less than 500/microliter through the course of administration. The eradication rate was 83.3% among 6 strains in which Gram-negative rods were detected. Side effects were minimum; skin rash in 1 case, slight elevation of APTT in 3 and slight elevation of total bilirubin in 1. Thus, this combination antibacterial chemotherapy is an effective and safe regimen for the treatment of severe infections in patients with hematological disorders.

Thirty-one patients (median age, 44 years) with advanced hematologic malignancies were given thiotepa 15 mg/kg, and cyclophosphamide 120 (n = 14) or 150 (n = 17) mg/kg followed by unfractionated peripheral blood stem cell transplants (PBSCT) from genotypically identical siblings (n = 28) or one antigen mismatched family donor (n = 3). Donors were mobilized with granulocyte colony-stimulating factor 5 to 10 microgram/kg/d for 6 days and underwent two to three leukapheresis on days +5, +6, +7. The median cell yield per donor expressed/kg of recipients body weight was as follows: nucleated cells 13 x 10(8)/kg; CD34+ cells 6 x 10(6)/kg; colony-forming unit-granulocyte macrophage 38 x 10(4)/kg, and CD3+ cells 449 x 10(6)/kg. The diagnoses were chronic myeloid leukemia (n = 4), acute myeloid (n = 9) or lymphoid leukemia (n = 2), acute myelofibrosis (n = 2), multiple myeloma (n = 1), lymphoma (n = 6), chronic lymphocytic leukemia (n = 1) myelodysplasia (n = 6). Twenty-eight patients had advanced disease, 29 patients were first grafts, and 2 were second transplants 3 and 9 years after the first. Neutrophil counts of 0.5 x 10(9)/L and platelet counts of 30 x 10(9)/L platelets were both achieved on day +14 (median). Engraftment could be proven by sex markers or DNA polymorphism in 29 of 31 patients: one had early leukemia relapse and one patient was unevaluable because of early death. Acute graft-versus-host disease (GVHD) was scored as minimal or absent (grade 0 to 1) in 14 patients, moderate (grade II) in 13, and severe (grade III to IV) in four. Causes of death were leukemia (n = 4), acute GVHD (n = 4, with associated cytomegalovirus infections in three), sepsis (n = 1), liver failure (n = 1), multiorgan failure (n = 1), and hemorrhage (n = 1). The actuarial transplant mortality is 29%, the actuarial relapse rate 22%. Nineteen patients survive with a median follow up of 288 days (100-690). The actuarial 2-year survival is 57%. Three patients received PBSCT from family donors mismatched for one class II antigen: all engrafted, one developed grade I aGVHD; one died of leukemia on day +155; two are alive disease free 267 to 290 days postgraft. This study suggests that thiotepa cyclophosphamide followed by unfractionated PBSC allograft may be an alternative form of transplant for adults with advanced leukemia, also in the setting of one antigen mismatched donor. The engraftment is rapid with acceptable GVHD and relatively low transplant-related mortality.

To better define the incidence and causes of canine pancytopenia, we retrospectively evaluated the results of complete blood counts submitted to the University of Minnesota Veterinary Teaching Hospital during a 1-year period. Pancytopenia was defined as packed cell volume < 36%, total leukocyte count < 6,000/microliter or total segmented neutrophil count < 3,000/microliter, and platelet count < 200,000/microliter. Of 4,560 complete blood counts, 110 (2.4%) samples from 51 dogs met the criteria for pancytopenia. Eleven different disease processes were identified. These included chemotherapy-associated pancytopenia (n=22), parvovirus infection (n=5), malignant histiocytosis (n=5), idiopathic aplastic anemia (n=3), sepsis (n=3), myelodysplastic syndrome (n=3), immune-mediated hematologic disease (n=3), lymphoblastic leukemia (n=2), ehrlichiosis (n=2), estrogen toxicity (n=2), and multiple myeloma (n=1). Malignant histiocytosis and idiopathic aplastic anemia occurred more frequently than was expected. Doxoruicin was the chemotherapeutic agent associated with pancytopenia. Hematologic recovery and patient survival time varied with the cause of pancytopenia; therefore, a specific diagnosis was essential for establishing prognosis. Differentiation among causes of pancytopenia requires a systemic approach that includes elimination of infectious and drug-induced causes, and examination of bone marrow aspiration and core biopsy specimens.

A 69-year-old man with relapsed acute lymphoid leukemia was treated with adriamycin, vincristine, and prednisolone. During this chemotherapy, the patient developed sepsis and meningitis. Although many kinds of antimicrobial drugs, including imipenem, meropenem, amphotericin-B, and gamma-globulin were administered, the patient died of respiratory failure. A positive result for Enterococcus faecalis was obtained in both blood and cerebrospinal fluid culture. Autopsy revealed multiple small erosions in the lower esophagus. Histopathological examination showed multiple nuclear inclusion bodies of herpes simplex virus in the squamous epithelial cells at the edge of the erosions. Moreover, proliferation of micrococci was observed at the base of the erosions and in the lumina of the submucosal small vessels. These findings suggested that E faecalis entered the blood circulation from this lesion. In many patients with febrile neutropenia, the pathogenesis of infection remains unclear. Our case seems significant for clarifying the focus and pathogenesis of febrile neutropenia.

Clinical effects and safety of cefozopran (CZOP) were evaluated by the Okayama Bone Marrow Transplantation Group. Twenty-five patients expected to experience febrile neutropenia during induction chemotherapy or consolidation chemotherapy of acute leukemia were enrolled between July 2000 and November 2002. CZOP was administrated by drip infusion at 4g/day bid for a minimum of 3 days. The clinical effects and safety were evaluated in 20 patients with fever of 37.5 degrees C or more from a clinically suspected infection. The underlying disease was acute myeloid leukemia in 17 patients, acute lymphoid leukemia in 1 and acute promyelogeneous leukemia in 1. The complicating infections were sepsis and suspected sepsis. Clinical efficacy was excellent in 11 patients, good in 1, fair in 2 and poor in 6, with an efficacy rate of 60.0%. The efficacy rate in patients whose albumin levels before therapy were less than 3.8 g/dl was 37.5%, whereas the rate in patients whose albumin levels before therapy were between 3.8 g/dl and 5.3 g/dl was 80.0%. The efficacy rate in patients whose neutrophil counts before therapy were less than 100/microliter was 50.0%, whereas the rate in patients whose neutrophil counts after therapy were less than 100/microliter was 53.8%. The efficacy rate in patients whose neutrophil counts both before and after therapy were less than 100/microliter was 37.5%. Side effect of exanthema was observed in 1 patient. These results indicate that CZOP is an effective and safe antibiotic for the treatment of febrile neutropenia in patients with hematological malignancies.

Our patient was a 61-year-old man with hormone-refractory prostate cancer and a rapidly rising serum prostate-specific antigen level. During the course of therapy for prostate cancer, abnormal blood counts and subsequent bone marrow biopsy led to a diagnosis of acute lymphoblastic leukemia. He was treated with a chemotherapeutic regimen in standard use for lymphoblastic leukemia, which resulted in an unusual response of his prostate cancer, with declining serum prostate-specific antigen levels that had reached undetectable levels at the time of the patient's death from acute sepsis and leukemic relapse. Autopsy showed minimal evidence of prostate cancer, localized to the prostate.

We evaluate the outcomes in children with acute leukemia who received allogeneic hematopoietic stem cell transplantation (HCT) using unrelated donor. Fifty-six children in complete remission (CR) received HCT from unrelated donors between 2000 and 2007. Thirty-five had acute myeloid leukemia, and 21 had acute lymphoid leukemia. Stem cell sources included bone marrow in 38, peripheral blood in 4, and cord blood (CB) in 14. Four patients died before engraftment and 52 engrafted. Twenty patients developed grade II-IV acute graft-versus-host disease (GVHD) and 8 developed extensive chronic GVHD. With median follow-up of 39.1 months, event free survival and overall survival were 60.4% and 67.5%, respectively, at 5 yr. Events included relapse in 10 and treatment-related mortality (TRM) in 10. The causes of TRM included sepsis in 4, GVHD in 4 (1 acute GVHD and 3 chronic GVHD), veno-occlusive disease in 1 and fulminant hepatitis in 1. Patients transplanted with CB had event free survival of 57.1%, comparable to 63.2% for those transplanted with other than CB. In conclusion, HCT with unrelated donors is effective treatment modality for children with acute leukemia. In children with acute leukemia candidate for HCT but lack suitable sibling donor, unrelated HCT may be a possible treatment option at the adequate time of their disease.

Severe sepsis defined as infection-induced organ dysfunction or hypoperfusion abnormalities predispose to septic shock and increased mortality in neutropenic setting. We aimed at determining predictors of severe sepsis in neutropenic patients. Between 1 October and 31 December 2007, 41 patients (21 with acute myeloid leukemia, 19 with acute lymphoid leukemia and one with autologous stem cell transplantation for a mantle cell lymphoma) with chemotherapy-induced neutropenia (<0.5 x 10(9)/l) lasting for more than 7 days were included in this study. The median age was 28 years (range: 3-58 years). All patients were on oral antibacterial (colistin and gentamicin) and anti-fungal (amphotericin B) prophylaxis. The first neutropenic febrile episode was treated with piperacillin/tazobactam and colistin IV; if the patient remains febrile at 48 h from the start of this first line of treatment, amphotericin B i.v. is added. Imipenem was introduced in the case of non-response and finally glycopeptides were introduced according to the IDSA criteria. Severe sepsis and septic shock are defined according to the criteria of the consensus conference of the ACCP/SCCM excluding the leukocyte count since all the patients were neutropenic. Ninety-four febrile episodes were observed: 27 microbiologically documented (28.7%), six clinically documented (6.3%) and 61 fever of unknown origin (65%). Microbiologically documented infections were: 13 Gram-negative organisms, 11 Gram-positive organisms and three combined (Gram+ and -). Clinically documented infections were pneumonia (two), neutropenic enterocolitis (one), sinuses infection (one) and cutaneous infection (two). Severe sepsis accounted for 22 febrile episodes. Factors associated with the occurrence of severe sepsis were: hypophosphatemia (<0.8 mmol/l; p=0.05, OR=3.9, 95% CI: 1.3-45.7), hypoproteinemia (<62 g/l; p=0.006, OR=4.1, 95% CI: 1.4-11.4) and non-adapted antibiotherapy at the onset of severe sepsis (p=0.019, OR=2.7, 95% CI: 1.02-7.39). However, heart rate/systolic blood pressure ratio <1.1 (p<0.001, OR=0.1, 95% CI: 0.03-0.31) and Creactive protein <80 mg (p=0.001, OR=0.14, 95% CI: 0.04-0.54) were not predictive.

Corynebacterium jeikeium has been recognized as an important cause of infection, particularly among neutropenic patients who have central venous catheter (CVC). Routine use of tigecycline in children is not yet approved. Here in we present a child with relapsed-refractory lymphoblastic leukemia who was successfully treated with tigecyline due to multi-drug-resistant C. jeikeium sepsis without removal of CVC. Our case highlights the use of tigecycline where there are no alternatives. Further studies regarding the efficacy and safety of tigecycline in pediatric patients are needed.

Stem cells are undifferentiated cells with the ability of proliferation, regeneration, conversion to differentiated cells and producing various tissues. Stem cells are divided into two categories of embryonic and adult. In another categorization stem cells are divided to Totipotent, Multipotent and Unipotent cells.So far usage of stem cells in treatment of various blood diseases has been studied (such as lymphoblastic leukemia, myeloid leukemia, thalassemia, multiple myeloma and cycle cell anemia). In this paper the goal is evaluation of cell therapy in treatment of Parkinson's disease, Amyotrophic lateral sclerosis, Alzheimer, Stroke, Spinal Cord Injury, Multiple Sclerosis, Radiation Induced Intestinal Injury, Inflammatory Bowel Disease, Liver Disease, Duchenne Muscular Dystrophy, Diabetes, Heart Disease, Bone Disease, Renal Disease, Chronic Wounds, Graft-Versus-Host Disease, Sepsis and Respiratory diseases. It should be mentioned that some disease that are the target of cell therapy are discussed in this article.
