A report of 27 drug induced agranulocytosis is presented in a period of 13 years. The rate of the disease was 0.12% of the total number of patients. Cases due to cytostatical and radiation treatment were not included. According to bone-marrow cellularity patients were divided into hypo- and hyper-cellular groups. The clinical findings were similar in both groups and the majority of patients recovered. Two patients died, both in the hypocellular group: the first due to mycotic pulmonary infection, the other after massive pulmonary embolism but after complete haematological recovery. Bone-marrow plasmocytosis was slightly expressed in the hypocellular group. The normal leukocyte number appeared after treatment within 3-25 days. Recurrent agranulocytosis was observed in four patients and permanent leukopenia developed in five. The leukocyte-agglutination test was positive in 10 cases only, but the leukocyte migration test was positive in all investigated cases except two. Five patients had a previous history with idiosyncrasy. Treatment was started with antibiotics, corticosteroids and with antimycotic drugs. Sterile island and granulocyte-transfusion was applied in seriously ill patients with septicemic complications only.

Eleven of 204 children with nephrotic syndrome had thrombotic complications: arterial thrombosis in five, venous thrombosis in four, and pulmonary embolism in two. Fifty-one episodes of thromboembolism were recognized in 116 adult patients with nephrotic syndrome. Despite the lower incidence, thromboembolic complications tended to be more severe in children. In vitro indices of hemostasis and clinical evidence of thromboembolic complications were compared in children and adults. Antithrombin III concentrations and activities were abnormal in seven of 10 children, but in only two of 32 adults. In both groups, alpha 2-macroglobulin was elevated, but more markedly so in children. No evidence for circulating granulocyte-derived proteases (elastase/antielastase complexes) was noted in either group. Protein C was significantly elevated in children with nephrotic syndrome, but was normal in adults. Children also differed from adults with nephrotic syndrome in laboratory evidence of subthreshold disseminated intravascular coagulation (i.e., elevated soluble fibrinogen monomeric complexes and fibrin degradation products) and indicators of in vivo platelet activation (elevated beta-thromboglobulin). The more severe coagulation abnormalities in children may be linked to the more pronounced hypoalbuminemia.

Fourteen patients with advanced solid tumors were included in a phase I trial of recombinant human E coli derived granulocyte-macrophage colony-stimulating factor (GM-CSF) given daily subcutaneously for 10 consecutive days. Dose levels were increased from 250 micrograms/m2 to 500, 750 and 1,000 micrograms/m2. Adverse effects were mainly fever, local irritation, lethargia, arthalgia. Three patients did not complete the 10-day cycle: one patient died due to progressive disease without toxic effects related to GM-CSF, one was withdrawn because of suspicion of pulmonary embolism (not confirmed), one patient had hypotension, not recurring after treatment with GM-CSF. Although the maximum tolerated dose was not reached, the trial was stopped at 1,000 micrograms/m2, considering the satisfactory response and the high white blood cell counts observed with lower dose levels. N-fold increases of leucocyte count ranged between 4.2 and 8.2 for the first dose level (250 micrograms/m2), 4 and 10.1 for 500 micrograms/m2, 8.5 and 12.3 for 750 micrograms/m2 and 5.6 and 8.3 for 1,000 micrograms/m2. Increases of granulocyte, neutrophil and eosinophil counts had a similar pattern with a weaker response at 1,000 micrograms/m2 (two patients who completed the cycle). In contrast, even for the first three levels, no dose response relationship was shown for increases of monocytes (between 2.8 and 12 n-fold whatever the dose), or lymphocytes (between 1.7 and 10.7 n-fold whatever the dose). Decreases of platelets (between 6 and 55%) were observed, followed by a rebound after stopping treatment. No modifications of erythrocyte count were observed. Subcutaneous GM-CSF was well-tolerated up to 1,000 micrograms/m2 during a 10-day course. Hematological effects were observed from the first dose level of 250 micrograms/m2.

The patient, a 64-year-old woman, was diagnosed as having large cell carcinoma(stageIV)eighteen months ago. She received long-term chemotherapy, and her disease stabilized. She was admitted to our hospital with dyspnea and diagnosed with a pulmonary embolism by chest computed tomography(CT)and angiography of pulmonary artery. As a result of thrombolytic therapy and anticoagulant therapy, the thrombus decreased in size and her condition improved. Insertion of a vena cava filter and continuation of anticoagulant therapy were performed to prevent recurrence of PE. In this case, there were many prothrombogenic factors such as advanced malignancy, a long period of chemotherapy, corticosteroids, granulocyte-colony stimulating factor(G-CSF)and decreased physical activity. Thrombosis is a frequent complication in cancer patients and represents an important cause of morbidity and mortality. Great care should be taken for complications of thrombosis in cancer treatment.

The use of erythropoietic agents has been associated with an increased risk of venous thromboembolic events (VTEs), especially in patients with underlying malignancies. However, it is not known whether there is an increased risk of VTE associated with granulocyte growth factors. We reviewed 621 patients undergoing PBSC mobilization using granulocyte growth factors, alone or in combination with CY. Patients with a diagnosis of AL amyloidosis (AL: 114; 18%), multiple myeloma (MM: 278; 44%) Hodgkin lymphoma (HL: 20; 3%) or non-Hodgkin lymphoma (NHL: 209; 33%) were included. Symptomatic VTE occurred in six (0.97%) patients: two AL, two MM and two NHL. Of the six patients, two had pulmonary embolism, one developed deep vein thrombosis and three developed symptomatic catheter related thrombosis. Two patients with AL had heparin-induced thrombocytopenia and thrombosis. We found a low incidence of VTE among patients undergoing PBSC mobilization.

Continuous dopaminergic stimulation (CDS) has been an important strategy of drug development for the treatment of Parkinson's disease (PD). Rotigotine is a non-ergoline D3/D2/D1 dopamine agonist for treating PD. As a new treatment option for CDS, rotigotine-loaded microspheres (RoMS), a long-acting sustained-release microspheres for injection with poly(lactide-co-glycolide) as drug carrier, are now being evaluated in clinical trial. In this study, subchronic toxicity of RoMS in SD rats has been characterized via intramuscular administration with RoMS (0-240 mg/kg/week) on a consecutive weekly dosing schedule for 3 months followed by 1-month recovery period. The No Observed Adverse Effect Level (NOAEL) was 45 mg/kg/week. One male at 240 mg/kg died from an extensive pulmonary embolism. The major toxicological effects were associated with the dopamine agonist-related pharmacodynamic properties of rotigotine (e.g. hyperactivity and stereotype, enlarged ovary, sporadic gastric mucous membrane lesions, decreased body weight, food consumption and prolactin, and increased mononuclear cell, neutrophil granulocyte, aspartate aminotransferase and alanine aminotransferase) and foreign body removal reaction induced by poly(lactide-co-glycolide) and carboxymethycellulose sodium. At the end of recovery period, all findings had recovered to a normal level or to a certain degree except foreign body reaction at injection sites. RoMS has exhibited high safety on SD rats.

Growth arrest-specific 6 (Gas6) is widely expressed in leukocytes, platelets, endothelial cells, and monocytes. It regulates various processes including granulocyte adhesion to the endothelium, cell migration, thrombus stabilization, and cytokine release. In humans, increased plasma Gas6 levels have been described in patients with sepsis and septic shock. In this study, Gas6 concentrations were measured in postmortem serum from femoral blood in a series of sepsis-related fatalities and control cases. The aims were twofold: first, to determine whether Gas6 can be reliably determined in postmortem serum; and second, to assess its diagnostic potential in identifying sepsis-related deaths. Two study groups were prospectively formed, a sepsis-related fatalities group (24 cases) and a control group (24 cases) including cases of deep vein thrombosis and fatal pulmonary embolism, cases of systemic inflammatory response syndrome in severe trauma, cases of end-stage renal failure, and cases of hanging (non-septic, non-SIRS, non-end stage renal failure cases). The preliminary results of this study seem to indicate that Gas6 can be effectively measured in postmortem serum. However, Gas6 levels in sepsis-related fatalities do not appear to be clearly distinguishable from concentrations in pulmonary embolism, severe trauma, and end-stage renal failure cases. These findings tend to support previous reports that indicated that Gas6 behaves as an acute phase reactant and can be considered a general marker of inflammation rather than a specific biomarker of sepsis.
