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.

Myeloma remains incurable with a median survival of 4 years, but outcome can be improved by the use of high-dose therapy. We used the etoposide, methylprednisolone, cytarabine and cisplatin (ESHAP) regimen as second-line therapy in 42 newly diagnosed myeloma patients who had failed vincristine, adriamycin and dexamethasone (VAD)- type therapy (n = 36), responded to first-line treatment but persisted in having significant residual marrow plasmacytosis (n = 5) or failed prior stem cell harvesting (n = 1), with the dual aim of improving disease response and mobilizing peripheral blood stem cells. Fourteen of 21 (67%) patients with no change or progressive disease after VAD responded to ESHAP; seven of 12 (58%) patients with minor response converted to partial response. Marrow plasmacytosis fell from a median of 52% at diagnosis to 23.5% after primary therapy and to15% after ESHAP. ESHAP chemotherapy was well-tolerated. There were 11 admissions due to febrile neutropenia (n = 7), nausea and vomiting (n = 2), pneumonia (n = 1) and perforated bowel (n = 1). Renal function deteriorated in 13 of 42 patients after ESHAP, but none required renal support. ESHAP mobilization was performed in 32 patients of whom 87% achieved a CD34(+) yield >2 x 10(6)/kg. In all, 38 patients proceeded to high-dose therapy. The overall survival for all patients was 62% at 4 years following ESHAP. We conclude that ESHAP has acceptable toxicity and efficient stem cell mobilizing capability, effectively cytoreduced this chemoresistant group of patients, and did not appear to adversely affect transplant outcome.

Multiple myeloma is associated with a susceptibility to bacterial infections, specifically for encapsulated organisms such as Streptococcus pneumoniae. However, severe bacterial infection as the initial presentation of this disease has been rarely reported. The most common presenting features are anemia, lytic lesions, hypercalcemia, and renal failure. We report two cases of pneumococcal bacteremia as the initial manifestation of an underlying multiple myeloma. The first case is of a 68-year-old woman with pneumococcal pneumonia and bacteremia, presenting with a white blood cell count of 900/microL and mild anemia. Further work-up disclosed monoclonal IgG kappa and 50% plasma cells in bone marrow. Her course was complicated by acute renal failure requiring hemodialysis. The second patient is a 57-year-old man presenting with acute pneumococcal meningitis and bacteremia. Due to prior bacterial epiglottitis, further work-up disclosed IgG lambda monoclonal spike and 40% plasma cells in bone marrow. Both cases responded to antibiotic therapy without complications. These two cases add to the few patients described in the literature with pneumococcemia as the first sign of multiple myeloma. Features that were common in most of these cases, and that should lead to a suspicion of myeloma in an otherwise asymptomatic patient, are S. pneumoniae bacteremia, leukopenia, mild anemia, history of prior bacterial infections, and indirect evidence of a paraproteinemia, such as increased total protein levels with low albumin.

A 66-year-old man was referred to our hospital for the treatment of refractory multiple myeloma with thalidomide. He had a history of an interstitial pneumonia of unknown etiology two months before admission. Eight days after starting 200 mg/ day of thalidomide, he developed dyspnea and fever, followed by a macropapular rash in the trunk. The dyspnea got worse and a CT scan revealed interstitial pneumonia 16 days after the treatment. He required mechanical ventilatory support. Bronchoalveolar lavage fluid revealed eosinophilia, suggesting a thalidomide-induced interstitial pneumonia. Thalidomide was discontinued and methylprednisolone (1000 mg/d x 3 days) was started, and the pneumonia and rash markedly improved within six days. After that the patient contracted MRSA pneumonia and died of MRSA septicemia.

Proteasome inhibitors, a novel class of chemotherapeutic agents, enhance the antitumor efficacy of anthracyclines in vitro and in vivo. We therefore sought to determine the maximum tolerated dose (MTD) and dose-limiting toxicities of bortezomib and pegylated liposomal doxorubicin (PegLD). Bortezomib was given on days 1, 4, 8, and 11 from 0.90 to 1.50 mg/m2 and PegLD on day 4 at 30 mg/m2 to 42 patients with advanced hematologic malignancies. Grade 3 or 4 toxicities in at least 10% of patients included thrombocytopenia, lymphopenia, neutropenia, fatigue, pneumonia, peripheral neuropathy, febrile neutropenia, and diarrhea. The MTD based on cycle 1 was 1.50 and 30 mg/m2 of bortezomib and PegLD, respectively. However, due to frequent dose reductions and delays at this level, 1.30 and 30 mg/m2 are recommended for further study. Pharmacokinetic and pharmacodynamic studies did not find significant drug interactions between these agents. Antitumor activity was seen against multiple myeloma, with 8 of 22 evaluable patients having a complete response (CR) or near-CR, including several with anthracycline-refractory disease, and another 8 having partial responses (PRs). One patient with relapsed/refractory T-cell non-Hodgkin lymphoma (NHL) achieved a CR, whereas 2 patients each with acute myeloid leukemia and B-cell NHL had PRs. Bortezomib/PegLD was safely administered in this study with promising antitumor activity, supporting further testing of this regimen.

Recently, we have experienced significant number of patients diagnosed with non-specific interstitial pneumonia (NSIP) by open lung biopsy or video-assisted thoracoscopic surgery. The purpose of this study is to compare clinical and pathological features of idiopathic NSIP and NSIP associated with underlying diseases (mainly autoimmune disorders). Forty-six patients with histologically proven NSIP were retrospectively collected. Twenty-four patients had underlying diseases (12 polymyositis/dermatomyositis, 5 systemic sclerosis, 2 rheumatoid arthritis, 2 Sjogren's syndrome, 1 ulcerative colitis, 1 primary biliary cirrhosis, and 1 multiple myeloma). Twenty-two of the 46 patients had no underlying diseases. It was very difficult to distinguish idiopathic NSIP and NSIP associated with underlying diseases, clinically and radiologically. Pathologically, Lymphocytic pneumonitis was demonstrated in both groups, and it was impossible to distinguish idiopathic NSIP and NSIP associated with underlying diseases. Since generalized symptoms were not observed in patients with idiopathic NSIP, and clinical and pathological features were identical to NSIP with several autoimmune disorders, we postulate new clinical entities of "autoimmune interstitial pneumonia" in cases without underlying diseases.

The aim of this study was to assess the side effects and the efficacy of thalidomide alone or in combination with dexamethasone in relapsed multiple myeloma (MM) and to evaluate possible predictive factors for response rate and survival. Twenty-nine pretreated patients were enrolled, including 13 patients with a relapse after high-dose chemotherapy. The median number of relapses was 3 (range: 1-7). Twenty-two patients received thalidomide in combination with dexamethasone and seven patients thalidomide alone. The dosage of thalidomide was 400 mg/day and the dosage of dexamethasone 20 mg/m2 daily for 4 consecutive days every 3 weeks. Cycles of dexamethasone were given until maximal decline of myeloma protein was achieved, whereas therapy with thalidomide was maintained until disease progression. Responses occurred in 62% of patients, including 5 (17%) complete remissions and 13 (45%) partial remissions. The median event-free survival (EFS) was 7.2 months and the median overall survival (OS) 26.1 months. In multivariate analysis, pretreatment serum levels of soluble interleukin-2 receptor (sIL-2R) were a significant prognostic factor for EFS, and those of beta2-microglobulin (beta2M) and sIL-2R for OS. Serum levels of sIL-2R significantly increased after 3 weeks of treatment in 89% of patients, possibly representing lymphocyte activation induced by thalidomide. Two patients died of septic complications within 3 months after starting treatment with thalidomide and dexamethasone and one patient of herpes encephalitis after 26 months of treatment with thalidomide alone. Also, one case of pneumonia and one case of deep venous thrombosis of the lower limb occurred. Other side effects were somnolence, peripheral neuropathy, and bradycardia occurring in 35, 55, 38 and 55% of patients, respectively. The combination of thalidomide and dexamethasone is an effective therapy in heavily pretreated myeloma patients with a high response rate and acceptable toxicities. A powerful predictive factor both for EFS and OS was the pretreatment serum level of sIL-2R.

In this retrospective single-centre study, 96 consecutive myeloma patients were treated with melphalan 200 mg/m(2) with blood stem cell support as first-line therapy. Their mean age was 55 (38-65) years. The impact of renal function on stem cell collection yield, engraftment, transplantation-related toxicity and overall survival was studied. Glomerular filtration rate (GFR) was evaluated by iohexol clearance, a median 32 days before high-dose administration. Chronic renal failure (GFR <60 ml/min) was present in 19 patients, with severe failure (GFR <30 ml/min) in five patients, including one patient on haemodialysis. No relationship between GFR and stem cell collection yield or engraftment was observed, nor was the incidence of neutropenic fever or infectious complications related to GFR. Patients with subnormal renal function, however, were more often affected by severe mucositis. In addition, the two patients with severe GI bleeding, the two pneumonia patients who needed ventilator support and the only therapy-related death were noted in the five patients with severe renal failure. Lower iohexol clearance at the time of high-dose administration was found to have a poor impact on survival. A reduction of melphalan dose in patients with severe renal failure, here defined as iohexol clearance <30 ml/min, is suggested.

In order to identify the characteristics of patients with hematological malignancies (HM) in the presence/suspicion of any accompanying infectious disease, and to find the predictors of mortality in this group, hospital charts of patients with HM consulted by the Infectious Diseases (ID) team for signs/symptoms of any infection between January 1, 1997 and December 31, 2001 were retrospectively reviewed. A total of 1,132 consultations were done for 641 patients: 59.4% of the patients were male and the mean (+/-standard deviation) age of the study participants was 47.9+/-1.4 years. The most common underlying diseases were non-Hodgkin's lymphoma (30.9%), acute myelogenous leukemia (26.2%), and multiple myeloma (10.9%). Clinically and microbiologically documented infections and fever of unknown origin were observed in 43.3%, 38.1%, and 18.5% of the participants, respectively. Bloodstream infections were detected in 134 episodes (20.9%): 56.5% were caused by gram-negative microorganisms. In logistic regression analysis, the presence of pneumonia (OR 7.56, 95% CI 4.84-12.486), invasive fungal infection (OR 4.12, 95% CI 1.78-9.55), relapse or recent diagnosis of the underlying disease (OR 2.82, 95% CI 1.53-5.21) and neutropenia (OR 2.70, 95% CI 1.70-4.31) were identified as statistically significant predictors of mortality.

A 81-year-old man was diagnosed as multiple myeloma and had received melphalan for 6 years. After that, he developed acute myeloid leukemia (AML) with monosomy 7 and minor bcr/abl transcripts. Fluorescence in situ hybridization identified no detectable level of bcr/abl rearrangement. During chemotherapy for AML, minor bcr/abl transcripts disappeared and instead major bcr/abl transcripts emerged. He died of pneumonia 3 months later. At that time, neither minor nor major bcr/abl transcripts were seen. These observations suggest that certain therapy related leukemia may be susceptible to generate very small clones with bcr/abl rearrangements.
