80-year-old female was admitted to our hospital because of pancytopenia. Her peripheral and bone marrow examinations were performed. According to the criteria of FAB classification, the diagnosis was myelodysplastic syndrome (refractory anemia with excess of blasts in transformation). Etoposide was administered to decrease leukemic blasts. However, she still had high fever and increasing of CRP. Hematological data also showed the increasing of WBC count, blast cells, and LDH enzyme. Antibiotics and anti fungal drugs were also not effective. She died of respiratory failure, although the cautions and extensive treatment was tried. Autopsy findings revealed proliferation of mucor in the mucosa of stomach. So, we reported here a very rare case of gastric mucormycosis, localizing exclusively in the stomach which was difficult to diagnose while she was alive.

Anaemia is a common manifestation of juvenile rheumatoid arthritis (JCA). We have evaluated 26 JCA patients with anaemia and compared their laboratory parameters to those without anaemia. In the patients with anaemia, activation criteria such as erythrocyte sedimentation rate (ESR) and CRP were significantly higher than in those without anaemia. Anaemia was present in all systemic JCA patients and was present in 42% and 78% of the oligoarticular and polyarticular types, respectively. Serum iron levels and transferrin saturations were low in all, whereas serum iron-binding capacities of the patients were normal. Mean ferritin level was 249pg/l (range 8.46-1000pg/l). There was a significant correlation between ferritin levels and CRP and ESR (r = 0.48 and r = 0.55 respectively) (both p < 0.05). Epo levels were normal. Twelve (60%) of the bone marrow aspiration specimens stained positive for iron whereas 40% stained negative; there were also changes suggestive of myelodysplasia. Sideroblasts were also decreased in number. Thus, in these patients iron is not sufficiently transferred to the erythroid series and/or cannot be used by erythroblasts, accompanied by a possible absolute iron deficiency. Thus we suggest that the iron in JCA tends to be stored in the form of ferritin, not in an accessible form and impaired metabolism along with other factors are effective in the anaemia of JCA.

High serum concentrations of procalcitonin (PCT) have been found during bacterial and parasitic infections. This is a report of two cases of disseminated aspergillosis with moderate PCT increase in two 14-year-old girls after bone marrow transplantation (BMT) for myelodysplastic syndrome and Fanconi's anemia, respectively. In contrast, the important rise of serum CRP observed in these patients tends to demonstrate that the synthesis of these two proteins is under different control mechanisms.

The expansion of myeloma cells is regulated by cytokines, among which IL-6 is a major growth factor. It has been recently suggested that serum transforming growth factor beta 1 (TGF beta 1), a cytokine found in large amounts in alpha-granules of platelets, might play a role in multiple myeloma (MM). It was the purpose of this study to determine serum TGF beta 1 levels in MM patients and to seek a correlation with disease parameters. Measurements were done by ELISA. We studied 35 MM patients (19 stage II, 16 stage III, 20 IgG, 8 IgA and 6 BJ, 1 IgD) in different phases of the disease, 27 healthy individuals and 17 thrombocytopenic patients with other haematological diseases (three MDS, three congenital thrombocytopenia, 11 ITP). Overall samples from MM patients were included: 10 at diagnosis, 18 in remission and 32 in relapse. In normal controls TGF beta 1 serum levels ranged from 1 to 33 ng/ml (median 16.5 ng/ml). In both thrombocytopenic controls with other diseases and thrombocytopenic MM patients (seven samples), TGF beta 1 serum levels were very low (median 3.2 and 4.5 ng/ml respectively). In MM patients with PLT > 100 x 10(9)/L (53 samples), TGF beta 1 serum levels were in the normal range in patients without immunoparesis (1 to 27 ng/ml, median 16.6 ng/ml), whereas they were higher in patients with immunoparesis (polyclonal immunoglobulins (Igs) below lower normal reference values) ranging from 10.2 to 45 ng/ml (median 26.8 ng/ml) (P < 0.01). Serum TGF beta 1 levels fluctuated in the same patient at different times but not according to relapse or remission. Correlation was found only between serum TGF beta 1 levels and immunoparesis and not between serum TGF beta 1 levels and disease stage or Ig subtype nor with prognostic factors for MM (serum CRP, beta 2M or IL-6). This finding suggests that the remaining normal plasma cells are sensitive to the inhibitory action of TGF beta 1 on Ig production. In conclusion TGF beta 1 serum levels are very low in thrombocytopenic patients confirming that platelets are the major source of this cytokine. Furthermore, a strong correlation was found between TGF beta 1 serum levels and immunoparesis in MM patients.

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.

We describe the characteristics and outcome of inflammatory arthritis in patients with myelodysplastic syndrome (MDS) in a French multicenter retrospective study. Twenty-two patients with MDS (median age, 77.5 yr [interquartile range, 69-81]; 10 women) were included. Inflammatory arthritis presented as polyarthritis in 17 cases (77%) and with symmetric involvement in 15 cases (68%). At diagnosis, the median disease activity score 28 based on C-reactive protein (DAS28-CRP) was 4.5 [2-6.5]. Two patients had anti-citrullinated protein antibodies (ACPAs), and 1 had radiologic erosions. The median time between the diagnoses of arthritis and MDS was 10 months [6-42], with a median articular symptom duration of 3 months [2-8]. The diagnosis of both diseases was concomitant in 6 cases (27%); arthritis preceded MDS in 12 cases (55%), and occurred after MDS in 4 (18%). While the number of swollen and tender joints significantly decreased during follow-up, as did the median DAS28-CRP (from 4.3 [3.8-4.6] at baseline to 2.9 [1.75-3.3]; p < 0.05), CRP remained elevated (CRP >20 mg/L) in 8 patients (42%). Nevertheless, radiographic progression and new ACPA positivity were not observed during a median follow-up of 29 months [9-76]. While most of the patients were treated with steroids (n = 16) for arthritis, additional treatment was administered in only 4 patients (hydroxychloroquine, n = 2; sulfasalazine [Salazopyrin] and etanercept, n = 1, respectively). Eleven patients died during follow-up from acute myeloid leukemia (n = 5); infections (n = 3); or cerebral bleeding, cardiorespiratory failure, or undetermined cause (n = 1, respectively). Inflammatory arthritis associated with MDS can have various presentations and is often seronegative and nonerosive. Steroids alone are the most common treatment in MDS-associated arthritis, but that treatment is insufficient to control arthritis. Steroid-sparing strategies need to be identified.
