Recently new radioimmunoassay methods have been established to measure plasma concentrations of beta-thromboglobulin (beta-TG) and platelet factor 4 (PF4), platelet release products which are set free when platelets aggregate. Plasma concentrations of beta-TG and PF4 were investigated in disorders with increased thromboembolic risk. Extremely high concentrations of these platelet proteins were found in patients with venous thrombosis, pulmonary embolism, polycythemia vera, and chronic renal failure. Moderately increased beta-TG and PF4 levels were observed in patients with peripheral vascular disease, coronary artery disease, chronic rheumatoid arthritis, multiple myeloma, and diabetes mellitus. These data indicate, that plasma concentrations of beta-TG and PF4 are useful parameters for the evaluation of the "in vivo" platelet activity. By using these new methods for clinical applications special blood sampling conditions have been taken into account; moreover one has to consider that the plasma levels of the platelet "release products" are dependent from renal function.

High cardiac output failure/state (HCOF) is regular feature of some illnesses e.g. thiamine deficiency, hyperthyroidism, severe anemia, Paget's disease or arteriovenous fistulae. HCOF in multiple myeloma is reported quite rarely. 31-year-old man was admitted because of fatigue, dyspnea and subfebrilities. Heart rate was 116/min, sinus rythm blood pressure 110/60 mmHg. Chest film showed cardiomegaly with sings of interstitial pulmonary edema, echocardiography mild dilatation of the left ventricle with hyperkinetic wall motion and small pericardial effusion. Hemoglobin was 104 g/l, leukocyte count 13.5 x 10(9)/l with 30% of plasmatic cells. Serum protein electrophoresis demonstrated a monoclonal gammapathy, X ray studies of the skelet multiple osteolytic lesions. Diagnosis of plasmocytic leukemia-form of multiple myeloma was established and chemotherapy (vincristine + adriamycine + dexamethason) was started. Patient cardiac status deteriorated. Cardiac catheterisation demonstrated mean righ atrial pressure of 25 mmHg, mean pulmonary artery pressure of 28 mmHg and pulmonary artery wedge pressure of 24 mmHg. Co was 20.0 l/min (C.I. 11.5 l/min/m2). In continuing of chemotherapy and symptomatic therapy for heart failure patients status gradually improved and complete remission of the myeloma and normalisation of cardiac parameters was achieved. Heart failure in multiple myeloma patients has been attributed to amyloidosis of myocardium, hyperviscosity syndrome, co-existing CAD or anthracycline toxicity. HCOF should be considered in patients with clinical evidence of heart failure and normal left ventricular function.

Cardiac involvement in AL-amyloidosis due to a multiple myeloma is present in up to 90% of cases. We present two patients with cardiac symptoms in whom a hematologic disease could be diagnosed because of suspicious cardiac finding. The leading symptom was dyspnea. The routinely performed laboratory tests, especially the erythrocyte sedimentation rate and the electrophoresis, were normal. After exclusion of coronary artery disease an infiltrative cardiomyopathy was suspected because of the echocardiographic examination with marked left ventricular hypertrophy, the restrictive flow pattern at the mitral valve and the electrocardiogram with a low voltage in limb leads and absent R waves in left precordial leads. Further, hematologic workup confirmed the production of light chains due to a myeloma. If the echocardiographic examination and the electrocardiogram raises the suspicion of an infiltrative cardiomyopathy as the cause of dyspnea, an immunofixation should be done in spite of normal laboratory tests to confirm or rule out the presence of a light chain disease due to a myeloma.

Thalidomide has antiangiogenic properties and was found to be effective in patients with multiple myeloma (MM) when used in the setting of posttransplantation relapse. We have now analyzed risk factors associated with development of deep vein thrombosis (DVT) in a cohort of 535 patients treated with thalidomide with cytotoxic chemotherapy (VAD [vincristine/doxorubicin/dexamethasone], CAD [cyclophosphamide/doxorubicin/dexamethasone], DCEP [dexamethasone/cyclophosphamide/etoposide/cisplatin], or DT-PACE [dexamethasone/thalidomide/cisplatin/doxorubicin/cyclophosphamide/etoposide] or without cytotoxic chemotherapy (thalidomide and dexamethasone only). A total of 82 patients developed DVT, and the frequency was affected by a number of baseline characteristics. On multivariate analysis, the combination of thalidomide with chemotherapy including doxorubicin was associated with the highest odds ratio (OR) for DVT (4.3; P < or = 0.001); in addition, newly diagnosed disease (OR, 2.5; P = 0.001) and chromosome 11 abnormality (OR, 1.8; P = 0.048) were also independent predictors for DVT. With a median follow-up of 2.9 years, survival was inferior in patients with chromosome 13 abnormalities (P = 0.001), age > 60 years (P = 0.001), lactate dehydrogenase level > or = 190 IU/L (P = 0.002), and creatinine level > or = 2 mg/dL (P < 0.001). However, the development of DVT did not adversely affect survival when examined as a time-dependent variable and adjusted for standard risk features (hazard ratio, 0.8; P = 0.162).

High-dose chemotherapy followed by autologous blood stem cell transplantation is the standard treatment for myeloma patients. In this study, CAD (cyclophosphamide, adriamycin, dexamethasone) chemotherapy and a single dose of pegfilgrastim (12 mg) was highly effective in mobilizing peripheral blood stem cells (PBSCs) for subsequent transplantation, with 88% of patients (n = 26) achieving the CD34+ cell harvest target of > or = 7.50 x 10(6) CD34+ cells/kg body weight, following a median of two apheresis procedures (range 1-4) and with first apheresis performed at a median day 13 after CAD application (range 10-20). Patients treated with pegfilgrastim showed a reduced time to first apheresis procedure from mobilization compared with filgrastim-mobilized historical matched controls (n = 52, P = 0.015). The pegfilgrastim mobilization regimen allowed for transplantation of a median of 3.58 x 10(6) CD34+ cells/kg body weight while leaving sufficient stored cells for a second high-dose regimen and back-ups in most patients. Engraftment following transplantation was comparable to filgrastim, with a median time of 14 days to leucocyte > or =1.0 x 10(9)/l (range 10-21) and 11 days to platelets > or = 20 x 10(9)/l (range 0-15). The results of this study thus provide further support for the clinical utility of pegfilgrastim for the mobilization of PBSC following chemotherapy in cancer patients scheduled for transplantation.

Coronary heart disease and chronic heart failure are common and have an increasing frequency. Although interventional and conventional drug therapy may delay ventricular remodelling, there is no basic therapeutic regime available for preventing or even reversing this process. Chronic coronary artery disease and heart failure impairs quality of life and are associated with subsequent worsening of the cardiac pump function. Numerous studies within the past few years have been demonstrated, that the intracoronary stem cell therapy has to be considered as a safe therapeutic procedure in heart disease, when destroyed and/or compromised heart muscle must be regenerated. This kind of cell therapy with autologous bone marrow cells is completely justified ethically, except for the small numbers of patients with direct or indirect bone marrow disease (e.g. myeloma, leukaemic infiltration) in whom there would be lesions of mononuclear cells. Several preclinical as well as clinical trials have shown that transplantation of autologous bone marrow cells or precursor cells improved cardiac function after myocardial infarction and in chronic coronary heart disease. The age of infarction seems to be irrelevant to regenerative potency of stem cells, since stem cells therapy in old infarctions (many years old) is almost equally effective in comparison to previous infarcts. Further indications are non-ischemic cardiomyopathy (dilative cardiomyopathy) and heart failure due to hypertensive heart disease.

The aim of this study was to describe the occurrence of acute coronary syndromes in 3 cases of rituximab infusions. We reviewed the records of 3 patients with lymphoproliferative disorders who experienced acute coronary syndromes associated with their initial infusion of rituximab. All 3 patients received rituximab according to a standardized institutional rate schedule, and all received pre-medication with acetaminophen and diphenhydramine. The median age of patients was 61 years. One patient had known atherosclerotic heart disease, and 2 patients had risk factors for coronary artery disease. All patients had varying degrees of evidenced high tumor burden, including lymphocytosis, elevated lactate dehydrogenase values, bulky tumor masses, and bone marrow involvement by lymphoma. All 3 patients experienced fairly typical chest pain syndromes and experienced elevations of cardiac enzymes consistent with myocardial ischemia. One patient died of an arrhythmia that deteriorated into asystole, and 2 patients recovered and underwent coronary angiography. Acute coronary syndromes can be associated with the infusion of rituximab. Patients with a history of previous coronary artery disease or risk factors for coronary artery disease should be observed closely for signs of myocardial ischemia, particularly during the initial infusion. The occurrence of symptoms that could be ascribed to an acute coronary syndrome should always be taken seriously during the first rituximab infusion and investigated aggressively. Patients should be aware that this is a rare, albeit serious, complication of treatment with rituximab.

IgA pemphigus, resembling subcorneal pustulous dermatosis, represents a rare complication of IgA type monoclonal gammopathy. The patient dates the onset of initial symptoms of vesicular-bullous disease to 1990. She was first examined at our clinic in 2001 with the following conclusion "type IgA monoclonal gammopathy of unknown significance". The first immunosuppressive treatment of vesicular-bullous disorder was administered in 2003 (dexamethasone 20 mg on days 1-4 and 15-18 in monthly cycles + daily cyclophosphamide 50 mg). Cyclophosphamide was administered for 6 months in total and dexamethasone for further 3 months. During the treatment, intensity of the skin disorder ameliorated and monoclonal IgA levels decreased to non-detectable levels. Nevertheless, skin symptoms recurred immediately after dexamethasone treatment in its original intensity was terminated, even though the concentration of monoclonal immunoglobulin IgA remained below the sensitivity of quantitative detection for further 6 months (positive immunofixation only). Six rituximab 600 mg infusions were administered in a weekly interval after stopping cyclophosphamide and dexamethasone to prevent early recurrence of skin symptoms but this treatment was without any lasting effect. Transformation into multiple myeloma was identified in 2007. First line treatment (cyclophosphamide, adriamycin and dexamethasone - CAD) remained without any haematological or dermatological treatment response. Second line treatment (thalidomide, cyclophosphamide and dexamethasone - CTD) brought about significant deterioration of skin symptoms up to the clinical picture of erythrodermia. Third line treatment (bortezomib 1.3 mg/sqm i.v. on days 1,4, 8 and 15, cyclophosphamide 50 mg daily and dexamethasone 20 mg on days 1-4 and 15-18 in 28-day cycles - VCD) resulted in rapid decline in monoclonal immunoglobulin IgA concentrations immediately following the first cycle and to negative immunofixation after 5 cycles. In total, six VCD cycles were administered. The patient has had no skin symptoms from the third cycle of this treatment and complete skin and haematological remission has been maintained for 12 months after completion of bortezomib-containing treatment. Combined treatment containing bortezomib has proven useful in the treatment of IgA pemphigus accompanying monoclonal gammopathy of uncertain significance transformed into multiple myeloma.

Hematopoietic stem cell transplantation (HSCT) represents an extended period of physiologic stress. It is unknown whether patients with pre-existing coronary artery disease (CAD) may be poor transplant candidates. There are no data analyzing the risk of transplantation in this population. Sixty-nine patients with CAD who underwent 72 transplantations, autologous and allogeneic, were identified retrospectively. Fifty-five percent of these patients had prior percutaneous coronary intervention, 42% had verifiable history of myocardial infarction, and 23% had prior coronary artery bypass grafting. Outcomes were compared to 1109 patients without established CAD who underwent 1183 transplants during the same time period. Cancer diagnoses in the 2 groups were similar, predominantly lymphoma, multiple myeloma, and leukemia. There was no significant difference between the CAD group and the control group with respect to type of transplant (autologous 68% versus 64%, P = .612, myeloablative 86% versus 85%, P = .867). Treatment-related mortality was no different in the CAD group versus the control group (5.6% versus 4.9%, P = .777), nor were there differences in mortality at 1 year (15.3% versus 16.6%, P = .871), urgent intensive care unit admission (11.1% versus 9.9%, P = .686), or length of stay (25.5 days versus 28.4 days, P = .195). These findings suggest many patients with underlying coronary artery disease may be safely managed through hematopoietic stem cell transplantation.
