Serum levels of immunosuppressive acidic protein (IAP) in 105 patients with hematopoietic malignancies, there were 12 cases of acute myeloblastic leukemia, 1 acute monocytic leukemia, 13 myelomonocytic leukemia, 4 acute promyelocytic leukemia, 26 chronic myelogenous leukemia, 22 non-Hodgkin's lymphoma, 5 Hodgkin's disease, 6 adult T-cell leukemia, 5 acute lymphoblastic leukemia, 3 chronic lymphocytic leukemia, and 8 multiple myeloma. High levels of serum IAP were detected in all of the patients except chronic phase of CML, malignant lymphoma in stage I and II, and multiple myeloma. In the cases of malignant lymphoma, serum IAP levels in stage III and IV were higher with statistical significance (p less than 0.01) than those in stage I and II. Serum IAP levels in the patients with CML in blastic crisis were higher than in the chronic phase, so serum IAP levels are useful as one diagnostic parameters in blastic crisis. However, in patients with ANLL in relapse, serum IAP levels showed normal values. Serum IAP levels paralleled those of acute phase reactants such as alpha 1-acid glycoprotein , C-reactive protein, alpha 2-globulin, and alpha 1-antitrypsin, and had inverse correlations with PPD and PHA skin test.

L-selectin is a glycoprotein which is one of three members in a family of cell adhesion molecules called selectins. L-selectin is present in distinct forms on both neutrophil granulocytes and lymphocytes, and it appears to play an important role in the early stages of leukocyte-endothelial cell interaction. Activation of leukocytes leads to shedding of the extracellular part of L-selectin which thus forms a soluble adhesion molecule, sL-selectin, which retains functional capacity and can be detected in serum. In the present study we have developed a specific, sensitive sandwich ELISA to measure the serum level of sL-selectin in patients with hematological and infectious disorders. Three patients with acute myeloid leukemia in remission and 1 patient with chronic myeloid leukemia in chronic phase were followed during bone marrow transplantation and the level of sL-selectin was found to correlate closely to the leukocyte counts with no detectable sL-selectin during periods of severe leukopenia. In 11 patients with chronic phase chronic myeloid leukemia and 13 patients with chronic lymphocytic leukemia the sL-selectin level was also found to correlate closely to the leukocyte count (R = 0.98; p = 0.001 and R = 0.83; p = 0.004 respectively). One CML patient with a leukocytosis of 385 x 10(9)/l was found to have an sL-selectin concentration 625 times above normal. Ten patients with acute pneumonia were evaluated at diagnosis and at the time of follow-up 4-8 weeks later. In all patients the initial sL-selectin level was higher than at follow-up. However, no close correlation between sL-selectin and leukocyte count or CRP (C-reactive protein) at the time of diagnosis was found. In summary, we have found that the sL-selectin level in human serum closely correlates to the leukocyte count in both CML and CLL and during bone marrow transplantation.

IL-10 plays an important role in the control of immune reactions during systemic infection. Here, IL-10 serum levels were investigated in patients after BMT. The IL-10 levels correlated with the clinical course of the patients and with serum levels of C-reactive protein (CRP) and neopterin (NP). A total of 26 patients with AML (7), ALL (12), CML (2), NHL (3) and multifocal Ewing's sarcoma (2) had received autologous (10) or allogeneic (16) BMT from related (9) or unrelated donors (7). Routine serum samples were obtained prior to BMT and at days 46 and 100 after BMT. However, in patients with severe complications additional samples were drawn at individual points in time. Prior to BMT, IL-10 serum levels were not detectable in 24/24 patients. Post-BMT, 11 patients developed elevated IL-10 levels, of these eight died of complications (DOC), whereas only one of 15 patients with undetectable IL-10 died of complications, indicating that high IL-10 levels were significantly correlated with severe life-threatening complications (chi2, P < 0.01). To determine the pathomechanism and role of the increased IL-10 levels, they were correlated to the respective NP and CRP serum concentrations. CRP and NP concentrations were found significantly elevated in patients with detectable IL-10, indicating a severe acute phase reaction associated with macrophage activation. In conclusion, high IL-10 serum levels in patients after BMT were significantly associated with fatal outcome. Since IL-10 is a strong suppressor of T cell immunity, high IL-10 production in patients with severe complications such as septic shock or GVHD > grade II after BMT might lead to functional immunodeficiency contributing to the poor prognosis of these patients.

The tyrosine kinase activity of the BCR/ABL fusion protein is required for the transformation in patients with chronic myeloid leukemia. The tyrosine kinase inhibitor STI571 inhibits the BCR/ABL and ABL kinase activity and consequently inhibits growth of BCR/ABL-positive cells. However, resistance to STI571 has been demonstrated in Ph+ cell lines and in CML patients and can be explained in some cases by point mutations within the ATP-binding pocket or amplification of the bcr/abl gene. In previous investigations using a nu/nu mouse model, the binding of STI571 to elevated levels of the plasmaprotein -1 acid glycoprotein (AGP) was identified as an additional mechanism of resistance to this therapeutic approach. Here we provide data on the expression of AGP in CML patients under therapy with STI571. Patients received 400 or 600 mg STI571 daily and apart from clinical parameters we determined AGP and C-reactive protein (CRP) plasma levels as well as the quantitative expression of both BCR/ABL and AGP mRNA in peripheral blood cells. Our data suggest that despite elevated AGP levels in 52% of our patients, no upfront resistance against STI571 was present. In conclusion, we demonstrated that during the first 13 weeks of STI571 therapy (i) plasma AGP levels in CML patients correlate with white blood cell count and stage of disease; (ii) patients with elevated AGP responded less rapidly to STI571; (iii) elevated AGP and CRP levels normalized in patients during treatment with STI571, although mRNA levels of AGP remained stable; (iv) initially normal levels of AGP remained in the normal range during treatment with STI571, indicating that STI571 does not trigger AGP expression in humans; and (v) in relapsed patients, elevation of AGP levels is present prior to hematological progress.

The cases of 3 patients with pyomyositis associated with hematological disorders are reported. A 40-year-old man in the blastic phase of chronic myelogenous leukemia and 2 men aged 46 and 71 years with neutropenia due to myelodysplastic syndromes all reported high fever and severe local myalgia and had marked elevation of C-reactive protein. Magnetic resonance imaging revealed muscle abscesses or fasciitis, and the findings led to the diagnosis of pyomyositis. Methicillin-resistant Staphylococcus aureus was isolated from the abscesses of 2 patients, and surgical drainage proved more effective than did antimicrobial agents. It should be recognized that pyomyositis is a possible source of infection in patients with hematological disorders.

We report on an 80-year-old man with rheumatoid arthritis (RA) who presented with chronic myelogenous leukemia (CML). Five years after the onset of RA, the CML diagnosis was made. The patient was treated for CML with 300 mg of imatinib mesylate (STI; signal transduction inhibitor 571) for 8 weeks. Laboratory tests showed that the C-reactive protein level, percentage of cells exhibiting the Philadelphia chromosome (Ph1), WBC count, and Lansbury index for RA all dropped respectively from 7.5 mg/dl to 1.0 mg/dl, 74.9% to 1%, 25, 100/microl to 9900/microl, and 51% to 14%. Administration of imatinib mesylate is felt to be effective in treating not only CML but also RA in the active stage.

We examined the clinical usefulness of 3 parameters of routine laboratory tests [platelet-large cell ratio (P-LCR), lactate dehydrogenase (LDH) and C-reactive protein (CRP)] in 84 patients with thrombocytosis-related diseases (reactive thrombocytosis, chronic myeloid leukemia, essential thrombocythemia and polycythemia vera). These thrombocytosis-related diseases were characterized using the 3 parameters P-LCR, LDH and CRP as follows: high P-LCR and high LDH in chronic myeloid leukemia; high CRP in reactive thrombocytosis; slightly high P-LCR and high LDH in essential thrombocythemia and polycythemia vera. For essential thrombocythemia and polycythemia vera, levels of P-LCR and CRP were nearly identical, but the LDH level in essential thrombocythemia was significantly higher than in polycythemia vera. These characteristics of P-LCR, LDH and CRP may be useful for simple and very rough differentiation of the thrombocytosis-related disease mentioned above.

Previous reports have suggested that a high serum cyclosporine A (CsA) level could result in a lower incidence of acute-graft-versus-host disease (aGVHD). An elevated serum lactate dehydrogenase (LDH) level has been reported to be an adverse predictor of outcome in stem cell transplantation (SCT) for acute myeloid leukemia. In this study, we retrospectively analyzed the records of 24 patients who received allogeneic SCT from an HLA-matched sibling donor for acute and chronic myelogenous leukemia. Univariate analysis showed that two factors (the serum CsA level at the third week after SCT and the LDH level at the third week after SCT) were significantly associated with the incidence of aGVHD among several variables (age, sex, stem cell source, cell dose, C-reactive protein, absolute lymphocyte count, conditioning regimens, and time to engraftment). A higher serum level of CsA and lower serum LDH level at the third week after SCT were associated with a lower incidence of aGVHD (P=0.015, 0.030). In multivariate analysis, the serum CsA level (hazard ratio [HR], 0.12; 95% confidence interval [CI], 0.022-0.652, P=0.0014) and serum LDH level (HR, 6.59; 95% CI, 1.197-36.316, P=0.030) at the third week after SCT were found to be independent factors that were significantly associated with the development of aGVHD. We conclude that a high CsA level and low LDH level might predict a low cumulative incidence of aGVHD after allogeneic transplantation from a matched sibling donor.

Outstanding results have been obtained in the treatment of chronic myeloid leukemia (CML) with first-line imatinib therapy. However, approximately 35% of patients will not obtain long-term benefit with this approach. Allogeneic hematopoietic stem cell transplantation (HCT) is a valuable second- and third-line therapy for appropriately selected patients. To identify useful prognostic indicators of transplantation outcome in postimatinib therapeutic interventions, we investigated the role of the HCT comorbidity index (HCT-CI) together with levels of C-reactive protein (CRP) before HCT in 271 patients who underwent myeloablative HCT for CML in first chronic phase. Multivariate analysis showed both an HCT-CI score higher than 0 and CRP levels higher than 9 mg/L independently predict inferior survival and increased nonrelapse mortality at 100 days after HCT. CML patients without comorbidities (HCT-CI score 0) with normal CRP levels (0-9 mg/L) may therefore be candidates for early allogeneic HCT after failing imatinib.

In the previous paper of ours we compared, prior to start any treatment, a number of immunological parameters in 24 chronic myeloid leukemia patients with the same number of healthy subjects matched by age and sex. We found significant differences in the levels of immunoglobulins, the C4 component of complement, the C-reactive protein, interleukin 6, the composition of lymphocyte population and the production of some cytokines by stimulated CD3+ cells. Eleven of these patients were followed longitudinally. After treatment with hydroxyurea, interferon alpha, imatinib mesylate and dasatinib, or various combinations thereof, hematological remission was achieved in all patients and complete cytogenetic remission in nine of them. There was a nearly general tendency towards normalization of the abnormalities observed in the patients at their enrollment.
