Between February 1991 and April 1994 induction chemotherapy of 32 adult consecutive patients under 65 years with de novo acute myeloid leukemias (AML) was started in the study UHKT-911. They were 19 women and 13 men, aged 18-63 (median 44) years. Their AML were classified according to the FAB classification: 3 M0, 3 M1, 9 M2, 14 M4, 3 M5. Induction chemotherapy consisted of 1-2 cycles with 3-4 doses of daunorubicin (DNR) 45 mg/m2/d i.v. and 14 doses of cytosine arabinoside (Ara-C) 200 mg/m2 per 3-h infusion every 12 hours. After the treatment patients, not being in complete remission, got the HD cycle with 10 high-doses of Ara-C 2000 mg/m2 per 3-h infusion every 12 hours i.v. and DNR 45 mg/m2/d i.v. on days 4 and 5, then the EMi cycle composed of etoposide 100 mg/m2/d i.v. for 5 days and mitozantrone 10-12 mg/m2/d i.v. on days 1, 3 and 5. Complete remission (CR) was achieved in 25 of 32 (78%) patients after 1-3 cycles. Five patients died between days 5 and 24 of treatment of infections, two patients were resistant to 4 cycles of induction therapy and survived 8.4 and 13.5 months. Three patients chose allogeneic bone marrow transplantation in their 1st CR from their relatives. Two of them have been living in CR for 115 a 110 months since diagnosis, the third died of sepsis on the day 52 after transplantation. Two patients in CR died of infections after their 2nd. consolidation cycle. Twenty patients in CR completed 2-4 consolidation cycles (1-3 HD, 1 EMi). Median of their CR duration was 17.8 (2-117) months. Relapse appeared in 12 cases after 4.4-34.8 (median 12.5) months, 8 patients (6 women and 2 men, aged 29-63 years) have remained longer than 5 years in their 1st. CR. Cytogenetic examination of their bone marrow showed a normal karyotype in 4 cases, 1x 46,XX,del(1)(p32p34), 1x 46,XX,16p+, 1x 47,XX,+mar, 1x 46,XX,del(5)(q22q33). After 62 months in CR a pancytopenia with dysplastic bone marrow changes developed in one of them, probably a secondary myelodysplastic syndrome, lasting for further 33 months. Event-free survival at 5 years was 27.5% (8/29 patients), significantly better (p = 0.046) against 7.5% (3/40) patients treated without HD cycles in the years 1982-1987. The same difference was observed in 7.5-year overall survival (p = 0.036) between the two studies, when 3 of 6 patients 60-64 years old remain in their 1. CR.

The role of high dose therapy, including autologous stem cell transplantation (ASCT) in indolent non-Hodgkin's lymphomas remains controversial. We evaluated a dose intense regimen of CHOP induction followed by high dose cyclophosphamide consolidation (CHOP-HC) versus CHOP alone in a prospective comparison to assess intensified therapy without ASCT. Twenty-five patients with previously untreated advanced stage indolent NHL were enrolled: follicular lymphoma, grade 1 (11 patients) and grade 2 (8 patients); small lymphocytic lymphoma (5 patients); and lymphoplasmacytic lymphoma (1 patient). All patients were treated as clinically indicated. The median age was 47 years (21-70). There were 15 males, and 10 females. Three patients had intra-abdominal stage II, 2 patients with stage III, and 20 patients with stage IV disease. All patients received induction with CHOP for 4 cycles (weeks 1, 4, 7, 10): cyclophosphamide 750 mg/m2 i.v., doxorubicin 50 mg/m2 i.v., vincristine 1.4 mg/m2 i.v. (2 mg capped dose) and prednisone 100 mg p.o. x 5 days. Following induction, responding patients were given consolidation with either high dose cyclophosphamide @ 3 gm/m2 i.v. for 3 doses with G-CSF (weeks 13, 15, 17) or 2 additional cycles of CHOP (weeks 13, 16), stratified by stage and bulk of disease. The overall response rate to CHOP was 92% (3 CR, 8 PR) and to CHOP-HC was 93% (4 CR, 8 PR). The overall response, complete response and partial response rates were comparable in both arms. Median progression free survival for CHOP was 15.9 and 23.0 months for CHOP-HC. At 74.3 months median follow-up, all patients in the CHOP arm have recurred; 3 patients in the CHOP-HC arm (3 CR) have not recurred. The median overall survival has not been reached (at 5 years, 77% OS for CHOP-HC versus 83% OS for CHOP alone]. Greater hematologic toxicity was observed with CHOP-HC resulting in an increased number of hospitalizations for sepsis. There were no treatment-related deaths. No myelodysplasia or acute leukemia has been seen to date. With no obvious improvement in CR and with greater hematologic toxicity than CHOP, CHOP-HC is not recommended for treatment of indolent non-Hodgkin's lymphomas.

Five patients with confirmed Fanconi's anemia (FA) and myelodysplasia and/or leukemia underwent stem cell transplantation (SCT) from related donors at KFSHRC. The median age at SCT was 12.6 year (range, 6.2-15 years). Conditioning regimen consisted of cyclophosphamide (CY) 5 mg/kg/day i.v. for 4 days, total body irradiation (TBI) 450 cGy in a single dose. Graft-versus-host disease (GVHD) prophylaxis was with cyclosporine and antithymocyte globulins (ATG). The median time to engraftment (defined as ANC>/=0.5 x 10(9)/l) was 16 days (range, 12-26 days). The median time to a self-sustaining platelet count of >/=20 x 10(9)/l was 27 days (range, 12-40 days). All patients engrafted. Two patients developed acute GVHD; one of the gut (grade 3) and the other of the skin (grade 1), and one patient developed chronic GVHD of the liver. Four are alive and well with no evidence of the disease; one patient died of bacterial sepsis after controlling her GVHD and clearing her pulmonary aspergillosis and CMV infection. We conclude that the use of low-dose CY plus TBI in patients with FA and MDS/AML undergoing SCT is adequate; the regimen is well tolerated and may be curative for such patients.

MDS are a diverse group of primary and secondary bone marrow disorders that are characterized by cytopenias in blood, prominent dysplastic features in blood or bone marrow, and normal or hypercellular bone marrow. MDS in cats are typically associated with FeLV infection. Dogs with MDS-RC and MDS-Er seem to respond to erythropoietin administration and have prolonged survival. Dogs with MDS-EB respond poorly to present treatments, and survival is short. Prognosis and probability of progression to acute myelogenous leukemia can be predicted based on the percentage of myeloblasts in bone marrow. Several experimental therapeutic modalities in human beings have been described that may be useful in treating MDS-EB in dogs and cats. Aplastic pancytopenia is a relatively rare disorder in dogs and cats. Causes include Ehrlichia spp, Parvovirus, and FeLV infections; sepsis; chronic renal failure; drug and toxin exposure; and idiopathic causes. Diagnosis is based on identification of multiple cytopenias in the blood and hypoplastic/aplastic bone marrow, with the marrow space replaced by adipose tissue. Treatment and outcome are dependent on determining the underlying cause of the bone marrow failure.

Orbital cellulitis caused by Aeromonas hydrophila developed in a 73-year-old male with a history of myelodysplastic syndrome. He was admitted because of fever, general malaise, pain as well as periorbital swelling in the right eye. Four days later, a yellowish pustule with purulent material was noted over right lower eyelid. Aeromonas hydrophila was isolated from the discharge. After administering intravenous cefuroxime 1,500 mg every 8 hours and topical ofloxacin eye oint, his symptoms subsided gradually. We present the first known case of orbital cellulitis from Aeromonas hydrophila in a patient with myelodysplastic syndrome. In patients with myelodysplastic syndrome, Aeromonas hydrophila should be listed as an important pathogen in any soft tissue infection including eyelid infection. Culture and adequate antimicrobial therapy are recommended, because rapid worsening may result in orbital cellulitis or even septicemia in patients with suppressed immune system.

We present two patients with myelodysplasia in association with Takayasu's arteritis (TA). In both patients intensive immunosuppressive treatment could not control the vascular inflammation. Subsequently both patients developed myelodysplasia, rapidly progressing to secondary acute myelogenous leukaemia. One patient had a peripheral blood stem cell transplant from a compatible sibling donor, but died of refractory leukaemia 5 months later. The other patient died of fungal sepsis. These are the first two patients reported to have TA associated with myelodysplasia/secondary leukaemia.

For a long time fibrinopeptide A(FPA), fibrinopeptide B(FPB), D-dimer, FM test, serum FDP, and thrombin anti-thrombin complex(TAT) are being used as molecular markers to for sure diagnose hypercoagulable state and thrombus formation. Indeed these molecular markers are very useful for diagnosing thrombus formation, disseminated intravascular coagulation(DIC), and the indicator of treatment of DIC. But these molecular parameters are not enough and difficult for prognosis of the disease or predicting the complication of patients as the most important subject for clinicians. The soluble fibrin monomer-fibrinogen complex (SF) is a complex coupling fibrin monomer and fibrinogen molecules to be formed in the early-activated state of blood coagulation. Thus such a molecular complex is expected to serve as a parameter for the diagnosis of thrombus formation and DIC, in particular its early stage. The aim of the present study is to evaluate a potential usefulness of a newly developed SF test utilizing an SF specific monoclonal antibody (IF-43). We measured SF together with established other parameters in 195 patients with DIC, subclinical DIC/hypercoagulable state, and non-DIC. The diagnosis of DIC was made based on a modified version of the criteria established by the Ministry of Health, Labor and Welfare of Japan. Underlying disease includes leukemia, malignant lymphoma, myelodysplastic syndrome (MDS), multiple injury, giant ovarian tumor, prostatic cancer with multiple bone metastasis, lung cancer, breast cancer with multiple lung and bone metastasis, severe pneumoniae, sepsis, hemophagocytic syndrome (HPS), and rheumatoid arthritis. The SF levels in DIC patients were significantly higher than those in the subclinical DIC/hypercoagulable state, and the non-DIC patients. Receiver operating characteristic (ROC) analysis shows that the specificity and sensitivity of the SF assay appears to be satisfactory. As the level of SF reflects the thrombin generation activity in plasma, it would serve as a strong tool to selectively kick up the state of thrombin generation. These results indicate that the SF could be a specific and reliable parameter for the diagnosis of DIC and contribute to legitimate managements of patients with DIC. The excessive life response to serious clinical insults, such as sepsis, severe pancreatitis, trauma and shock, is called systemic inflammatory response syndrome (SIRS). Once SIRS occurs, people may often die from serious complications such as adult respiratory distress syndrome (ARDS), acute lung injury (ALI), disseminated intravascular coagulation (DIC) and multiple organ failure (MOF). Especially, ALI followed by pneumoniae associated with SIRS could depend on patient's prognosis and life. That is to say, it seems to be urgent for clinicians to make differential diagnosis between Pneumoniae associated with SIRS and Coagulopathy (PASC) and Simple Pneumoniae (SP). Soluble fibrin monomer-fibrinogen complex(SF) is formed in the early-activated state of blood coagulation. Thus such a molecular complex is expected to serve as a parameter for the diagnosis of coagulopathy, in particular its early stage. The aim of the present study is to make differential diagnosis between Pneumoniae associated with SIRS and Coagulopathy (PASC) and Simple Pneumoniae(SP) by using a newly developed SF test utilizing an SF specific monoclonal antibody (IF-43). We measured SF together with established other parameters, hemogram, blood laboratory items in 7 patients with PASC and 17 patients with SP. The diagnosis of Pneumoniae was defined according to the criteria: clinical symptoms abnormal shadow in both Chest X-p and Chest CT, increased level of CRP, number of WBC. The diagnosis of SIRS was based on the criteria established by American College of Chest Physicians (ACCP)/Society of Critical Care Medicine (SCCM) Consensus Conference held in August of 1991 in Northbrook, IL (USA). Underlying disease includes leukemias, malignant lymphoma, myelodysplastic syndrome (MDS), multiple myeloma, idiopathic thrombocytopenia purpura(ITP), multiple injury (bone fracture), cerebral hemorrhage, enterocolitis, Appendicitis, lung cancer, larynx cancer, bronchiolitis obliterans organizing pneumonia(BOOP), chronic obstructive pulmonary disease(COPD), sepsis. The SF levels in PASC patients are significantly higher than those in SP patients (p < 0.001). Otherwise, there is no significant difference of the CRP levels between in PASC group and SP group (p < ns). There is no co-relationship between SF level and D-dimer level. Receiver operating characteristic (ROC) analysis shows that the specificity and sensitivity of the SF assay appears to be quite satisfactory. As the level of SF reflects the thrombin generation activity in plasma, it would serve as a strong tool to selectively kick up the state of thrombin generation. These results indicate that the SF could be a specific and reliable parameter for the diagnosis of PASC and contribute to legitimate managements of patients with PASC.

Mastocytosis is characterized by mast cell proliferation that may be limited to the skin (cutaneous mastocytosis) or may involve one or more extracutaneous organs, e.g., the bone marrow (systemic mastocytosis; SM). This study objective is to evaluate the features and outcome of patients referred to M. D. Anderson Cancer Center (MDACC) with SM. A search of the MDACC database from 1944 to 2002 was conducted for patients with SM and review of their clinical charts. Eighteen patients with mastocytosis were identified in the MDACC database; 15 (11 males and 4 females) had SM and available information. Two had associated myelodysplastic syndrome (MDS), and one had acute myeloid leukemia (AML). The median age was 58 years (range 31-80). Nine patients were treated with subcutaneous interferon-alpha, and only 1 experienced temporary control of the disease. Three of these patients were then treated with imatinib mesylate: transient improvement was noted in two patients. One patient underwent stem cell transplantation as first therapy and achieved complete remission; this patient had associated MDS and is now in complete remission for 8 years. The patient with associated AML was treated with high-dose cytarabine and idarubicin; he has been in complete remission for 16 months. One patient was treated with induction chemotherapy consisting of high-dose cytarabine and 2CDA but expired due to sepsis. Three patients received symptomatic therapy only; these were the only 3 patients who presented with normal blood counts. SM is rare and has no effective standard of care. Collaboration among academic centers to accrue enough patients to evaluate novel therapeutic strategies is needed.

On May 19, 2004, azacitidine (5-azacytidine; Vidaza(trade mark); Pharmion Corporation, Boulder, CO, http://www.pharmion.com) for injectable suspension received regular approval by the U.S. Food and Drug Administration (FDA) for the treatment of all subtypes of myelodysplastic syndrome (MDS). This report summarizes the basis for this approval. Effectiveness was demonstrated in one randomized, controlled trial comparing azacitidine administered s.c. with best supportive care (observation group) and in two single-arm studies, one in which azacitidine was administered s.c. and in the other in which it was administered i.v. The dose of azacitidine, 75 mg/m2/day for 7 days every 28 days, was the same in all three studies. In the randomized trial, study participants were well matched with respect to age, sex, race, performance status, MDS subtype, and use of transfusion during the 3 months before study entry. Patients in the observation arm were permitted by protocol to cross over to azacitidine treatment if their disease progressed according to prespecified criteria. During the course of the study, more than half of the patients in the observation arm did cross over to the azacitidine treatment arm. The primary efficacy end point was the overall response rate. Response consisted of complete or partial normalization of blood cell counts and of bone marrow morphology. The response rate in the azacitidine arm was about 16%; there were no responses in the observation arm. The response rates in the two single-arm studies were similar (13% and 19%). The responses were sustained, with median durations of 11 months and 17 months respectively. Responding patients who were transfusion dependent at study entry lost the need for transfusions. In addition, about 19% of patients had less than partial responses (termed improvement), and two-thirds of them became transfusion independent. Common adverse events associated with azacitidine treatment were gastrointestinal (nausea, vomiting, diarrhea, constipation, and anorexia), hematologic (neutropenia, thrombocytopenia), fevers, rigors, ecchymoses, petechiae, injection site events, arthralgia, headache, and dizziness. Liver function abnormalities occurred in 16% of patients with intercurrent hepatobiliary disorders and in two patients with previously diagnosed liver cirrhosis. Renal failure occurred in patients during sepsis and hypotension. There were no deaths attributed to azacitidine. Azacitidine, the first drug approved by the U.S. FDA for MDS, has a favorable safety profile and provides a clinical benefit of eliminating transfusion dependence and complete or partial normalization of blood counts and bone marrow blast percentages in responding patients.

Therapeutic approaches are not well established in patients with myelodysplastic syndrome (MDS). We evaluated response to cyclosporin A (CyA) in 19 cases with MDS who were enrolled for the study [13 refractory anemia (RA), 5 refractory anemia with excess of blasts (RAEB), and 1 refractory anemia with ringed sideroblasts (RARS)]. Bone marrow was normocellular in ten, hypercellular in five, and hypocellular in four cases. Fifteen patients were transfusion dependent and the rest were not transfusion dependent but with a hemoglobin range of 6.4-8.8 g% with a mean of 7.4 g%. CyA was given at a dose of 3-5 mg/kg per day. A major response was observed in seven patients with RA, which was sustained on follow-up. Four cases of RA showed minor response and two cases of RA did not respond to CyA therapy. A minor response was also seen in one RAEB and one RARS case, while one RAEB case that initially showed a major response relapsed on therapy. The first effect of therapy was evident after a mean period of 2.5 months. A rise in platelets and leukocyte count was seen in three and two cases, respectively. One case developed renal failure on therapy and later died of septicemia. Response to CyA was independent of bone marrow cellularity. CyA could be an effective mode of therapy in patients with MDS especially those having RA.
