[The effectiveness of G-CSF and GM-CSF in the adjunctive treatment of infections complicating chemotherapy of non-Hodgkin's lymphoma in children. Report of Polish Pediatric Leukemia/Lymphoma Treatment Group].

Total number of 252 cycles of GM-CSF-Leucomax Sandoz (5 mg/kg/day s.c.) and/or G-CSF Filgrastim Hoffmann-La Roche (5-10 mg/kg/day s.c.) was applied in 124 children aged from 0.5-20 years during neutropenia associated with chemotherapy of non-Hodgkin's lymphoma (NHL). Twenty four children with NHL treated according to the same chemotherapy protocol but without G-CSF and GM-CSF served as a control group. Our study have demonstrated the good efficacy of both G-CSF and GM-CSF therapy. They shortened the period of neutropenia, reduced the number of febrile days, infection's duration and decreased the frequency of infectious complications.

[MMC conditioning regimen (Melphalan, MeCCNU and cyclophosphamide) followed by allogeneic peripheral blood stem cells transplantation for chronic myeloid leukemia].

This paper reports 3 cases of allogeneic peripheral blood stem cell transplantation (Allo-PBSCT) for the patients with chronic myeloid leukemia (CML). The patients received MMC preparative regimen with high dose chemotherapy (Melphalan 170 mg/m2, p.o. on Day-5, MeCCNU 400 mg/m2, p.o. on Day-4, and Cyclophosphomide 60 mg/kg/day, i.v. on Days-3 and -2). The HLA-identical sibling donors received filgrastim (rhG-CSF) for mobilization at a dose of 300 micrograms/day for 6 days. Leukaphereses were done at the 6th day of mobilization. A median of 8000 ml (2 times total blood volume) of blood was processed the collecting: 2.5-4.5 x 10(8)/kg MNC, 12.8-20.0 x 10(6)/kg CD34+ cells (including 4.8-7.5 x 10(6)/kg CD34+CD33-, 8.0-13.0 x 10(6)/kg CD34+CD33+), and 3.5-4.3 x 10(5)/kg CFU-GM. Cyclosporin A and methotrexate were used for GVHD prophylaxis. Hematopoitic function recovered as for 14-20 days to > 0.5 x 10(9)/L of neutrophil count, and for 16-34 days to > 20 x 10(9)/L of platelet count. At day + 100, chromosome analysis of bone marrow cells showed that complete chimera without ph1 positive chromosome in Cases 1 and 3, and a partial chimera with 73% donor karyotype in Case 2. All patients now are in disease free survival. No episode of acute graft versus host disease (GVHD) developed. It was concluded that HLA matched sibling allogeneic PBSCT result in rapid hematopoitic reconstitution and the MMC conditioning regimen is effective both in leukemic cells eradication and in immunosuppression for stem cells engraftment, and the drug related toxicity could be tolerated by patients.

Clinical efficacy of rhIL-11.

Placebo-controlled clinical trials of recombinant human interleukin-11 (rhIL-11, also known as oprelvekin [Neumega]) in patients with nonmyeloid malignancies have demonstrated significant efficacy in preventing postchemotherapy platelet nadirs of < or = 20,000/microL, and reducing the need for platelet transfusions while continuing chemotherapy without dose reductions. The likelihood of requiring a platelet transfusion in rhIL-11-treated patients receiving chemotherapy is approximately 40% lower than the risk for untreated patients. Treatment with rhIL-11 appears to accelerate earlier recovery to platelet counts of 20,000/microL, 50,000/microL, and 100,000/microL, suggesting that patients treated with rhIL-11 are more likely to be able to receive their next chemotherapy cycle in a timely fashion. rhIL-11 shows sustained efficacy over multiple cycles of full-dose chemotherapy. Activity has also been demonstrated in pediatric patients with solid tumors. The use of rhIL-11 in combination with granulocyte colony-stimulating factor (G-CSF, filgrastim [Neupogen]) may also produce a synergistic hematopoietic effect, resulting in earlier neutrophil recovery. The recommended adult dose regimen for rhIL-11 is 50 micrograms/kg administered subcutaneously once daily beginning 6 to 24 hours after the administration of chemotherapy until a postnadir platelet count of > or = 50,000/microL is reached. The recommended pediatric dose of rhIL-11 is 75 micrograms/kg subcutaneously, once daily beginning 6 to 24 hours after the administration of chemotherapy until a postnadir platelet count of > or = 50,000/microL is reached. The administration of rhIL-11 for greater than 21 days has not been studied and therefore is not recommended.

Tolerability and side-effect profile of rhIL-11.

Safety data from two randomized phase II and one abbreviated phase III placebo-controlled, double-blind clinical studies in adult patients with nonmyeloid malignancies indicate that recombinant human interleukin-11 (rhIL-11, also known as oprelvekin [Neumega]) has an acceptable toxicity profile as therapy for the mitigation of chemotherapy-induced thrombocytopenia. Preliminary data also indicate that rhIL-11 is well tolerated by pediatric patients with similar types of cancers. Adverse events associated with rhIL-11 are generally mild or moderate, reversible with drug discontinuation, and easily managed. Many of the common adverse events of rhIL-11--including edema, dyspnea, pleural effusions, conjunctival injection, and in some patients, atrial arrhythmia--occur in association with fluid retention. However, these adverse events can be medically managed and need not limit the use of rhIL-11, particularly if ameliorative measures, such as salt restriction and occasional prophylaxis with a potassium-sparing diuretic to minimize peripheral edema, have been instituted along with close monitoring of fluid and electrolyte status. Such measures are suggested for any patient treated with a diuretic, especially patients with cancer who are receiving multiple medications that complicate overall care. Administration of sequential cycles of rhIL-11 treatment does not appear to result in an increased incidence of adverse events or bone marrow exhaustion. rhIL-11 does not appear to interact adversely with concomitantly administered chemotherapeutic agents or agents commonly used for supportive care, including granulocyte colony-stimulating factor (G-CSF, filgrastim [Neu-pogen]).

[Standards, options, and recommendations for the use of hematopoietic growth factors in oncology].

Four hematopoietic growth factors have marketing approval in France: filgrastime (G-CSF), malgraostime (GM-CSF), lenograstime (glycolysated G-CSF) and erythropoietin. A standards, options and recommendations document has not yet been established for erythropoietin which is excluded from this report. Administration of hematopoietic growth factors can be proposed in five clinical situations: primary prophylaxis, secondary prophylaxis, curative care, after myeloablative chemotherapy and hematopoietic stem cell grafting, and finally mobilization of peripheral stem cells. Primary prophylaxis: excepting therapeutic trials, the use of hematopoietic growth factors is recommended for clinical situations where a significant incidence of neutropenia with fever has been reported in randomized trials and in rare cases where there is an increased risk of severe infectious complications. Hematopoietic growth factors are indispensable for increasing the quality of cytapheresis peripheral stem cell harvesting.

A phase I trial of doxorubicin, paclitaxel, and valspodar (PSC 833), a modulator of multidrug resistance.

PURPOSE: P-glycoprotein is an efflux pump for many drugs including doxorubicin and paclitaxel. This study evaluated the coadministration of these drugs with the P-glycoprotein inhibitor valspodar (PSC 833) with the aim of determining: (a) maximum tolerated doses (MTDs) of doxorubicin followed by paclitaxel (DP); (b) the MTD of DP combined with PSC 833 (DPV), without and with filgrastim (G-CSF); and (c) the pharmacokinetic interactions of PSC 833 with doxorubicin and paclitaxel. EXPERIMENTAL DESIGN: For the first cycle, patients received doxorubicin as a 15-min infusion followed by paclitaxel as a 1-h infusion. For the second cycle, patients received reduced doses of DP with PSC 833 at 5 mg/kg p.o., four times a day for 12 doses. RESULTS: Thirty-three patients with various refractory malignancies were enrolled and assessable. The MTD of DP without PSC 833 was 35 mg/m(2) doxorubicin and 150 mg/m(2) paclitaxel. The MTD of DPV without G-CSF was 12.5 mg/m(2) doxorubicin and 70 mg/m(2) paclitaxel. The dose-limiting toxicity for both DP and DPV was neutropenia without thrombocytopenia. With G-CSF, the MTD for DPV was 20 mg/m(2) doxorubicin and 90 mg/m(2) paclitaxel. No grade 4 nonhematological toxicities were observed. Five partial and two minor tumor remissions were observed. Paired pharmacokinetics with and without PSC 833 revealed substantial drug interactions with both doxorubicin and paclitaxel. CONCLUSIONS: PSC 833 can be administered safely with doxorubicin and paclitaxel. The pharmacokinetic profiles of these drugs are significantly affected by PSC 833, requiring approximately 60% dose reductions for equivalent degrees of myelosuppression.

[Chronic myeloid leukemia associated with sustained severe pancytopenia after imatinib mesylate therapy].

A 73-year-old woman with chronic myeloid leukemia was treated with interferon-alpha, hydroxyurea, and busulfan before imatinib mesylate treatment. The leukocyte count was 8,400/; hemoglobin concentration, 12.0 g/; and platelet count, 19.7 x 10(4)/. She received 400 mg of imatinib mesylate for 17 days before the agent was discontinued because of pancytopenia. A bone marrow biopsy on the 87th day after the last imatinib mesylate administration demonstrated severe hypocellularity. She needed many RBC and Plt transfusions and filgrastim administration. Grade 4 neutropenia continued for 35 days and Grade 3 thrombocytopenia continued for over 122 days. Imatinib mesylate, an agent targeting BCR-ABL, is expected to be useful as an effective therapeutic agent for chronic myeloid leukemia. However the present case suggests that its appropriate dose is individually variable and we should carefully consider the former treatment, and the clinical stage of the disease before initiating imatinib treatment.

[Evaluation of the increasing serum lactate dehydrogenase caused by recombinant human granulocyte-colony stimulating factor].

OBJECTIVE: Increasing serum lactate dehydrogenase (LDH) is often caused by granulocyte-colony stimulating factor (G-CSF) for leukopenia following chemotherapy in patients with lung cancer. To evaluate the increase in LDH, we investigated the significance of its elevation and LDH isozyme during chemotherapy supported by recombinant human G-CSF (rhG-CSF). STUDY DESIGN: To exclude effects of liver diseases and chemotherapy-induced liver dysfunction, only patients in whom laboratory findings concerning liver function were within normal range were entered in this study. If leukocyte or neutrophil counts were less than grade 3, subcutaneous injection of 50 micrograms/m2 of filgrastim was given daily until leukocyte counts increased to more than 10,000/mm3. RESULTS: Sixty patients with unresectable lung cancer were enrolled in this study and the LDH isozyme was evaluable in 54 patients. Increasing LDH was observed in 38 patients(70.4%), and LDH isozyme was measured in these 38 patients. Increases in granulocytes and LDH isozymes were found to have a positive correlation. LDH2, LDH3, LDH4 and LDH5 increased significantly after rhG-CSF administration, although LDH 1 did not increase. CONCLUSION: It was found that a rapid increase in leukocytes by rhG-CSF induced an increase in LDH, especially LDH 3.4. Considering the results of principal component analysis and the distribution ratio of LDH isozymes in neutrophils, it is thought that elevation of LDH is reflected in the rapid production and consumption of neutrophils.

[Agranulocytosis due to anti-tuberculosis drugs including isoniazid (INH) and rifampicin (RFP)--a report of four cases and review of the literature].

We experienced 4 cases of agranulocytosis due to anti-tuberculosis drugs (rifampicin [RFP], isoniazid [INH], ethambutol [EB], streptomycin [SM] or pyrazinamide [PZA]) among some 6,400 tuberculosis patients who underwent chemotherapy over the past 20 years from 1981 to 2002 in our hospital, and the incidence rate of agranulocytosis was estimated at 0.06%. The 4 cases of agranulocytosis were as follows. CASE 1: A 51-year-old woman with right chest pain and fever was admitted to our hospital on Jan 4, 2001. The white blood cell (WBC) count was 5,200/microliter. The tubercle bacilli were cultured in her sputum. The treatment with INH 0.3, RFP 0.45, EB 0.75, PZA 1.2 g/day, allopurinol and teprenone was started on Jan 13. Pyrazinamide and allopurinol were stopped because of hyper-uric acidemia on Feb 7. Agranulocytosis and eosinophilia (WBC 1,300 [Neut 1%, Ly 57%, Eos 35%]) developed on Feb 13. All drugs were withdrawn and G-CSF drug nartograstim 100 micrograms was injected subcutaneously for 3 days. The WBC recovered to normal level and she was thereafter treated with INH, EB and Levofloxacin (LVFX) without any further trouble. Agranulocytosis in this case was supposed to be due to RFP. CASE 2: A 66-year-old man who had had nephrotic syndrome and hypothyroidism and has been treated with prednisolone 10 mg/day was admitted to our hospital on Aug 9, 2000 because of miliary tuberculosis. The tubercle bacilli were cultured in his sputum and the treatment with INH 0.3, RFP 0.45, and EB 0.75 g/day were started on Aug 10, but it was withdrawn on Aug 17 because of general skin eruption. After re-starting treatment with EB and INH on Aug 24, RFP was added in small dosage (0.05 g) on Oct 12, but agranulomatosis (WBC 2,300/microliter [Neut 2%]) developed on Nov 21, and all drugs were withdrawn again. The G-CSF drug filgrastim was used once subcutaneously, and WBC recovered immediately. He was thereafter treated with INH, EB, LVFX successfully. Agranulocytosis was supposed to be due to RFP. CASE 3: A 60-year-old woman without symptoms had abnormal chest roentgenograph, and consulted with our hospital on Aug 26, 2002. The broncho-alveolar lavage fluid was smear and culture-negative, but PCR-TB positive, and the case was diagnosed as pulmonary tuberculosis. Treatment with INH 0.3, RFP 0.45, EB 0.75, PZA 1.2 g/day, alloprinol 300 mg and rebamipide 300 mg/day was started on Sept. 5, 2002. Late in September, she complained of appetite loss. The laboratory data on Oct 3 revealed WBC 900/microliter (Neut 1%, Ly 94%), aspartate aminotransferase (AST) 199 IU/l, and alanine aminotransferase (ALT) 253 IU/l, showing agranulocytosis and drug-induced hepatitis. The chemotherapy was immediately withdrawn and she was admitted to our hospital on the next day. Glycyrrhizin derivative (SNMC) 40 ml was injected for 5 days, and WBC recovered, and AST and ALT also became normal. CASE 4: A 60-year-old man was admitted to our hospital on March 11, 1981 because pulmonary tuberculosis had recurred. He had been treated with SM, PAS and INH in 1973 for pulmonary tuberculosis. On admission examination of blood count and blood chemistry were normal. Treatment with RFP, INH and SM was started on March 11. He stopped out from the hospital on April 17, but in a few days he returned back with sore throat, lower lip swelling and gingival bleeding. Blood cell count on April 24 showed pancytopenia with RBC 226, Hb 7.5, WBC 800 (Ly 96%, Eos 4%) and Plt 10,000/microliter. The bone-marrow showed NCC (nuceated cell count) of 5,500, and megakaryocyte 0. Thereafter ground glass appearance shadows were seen on the whole lung field, and he died May 26. Autopsy showed generalized aspergillosis. It was strongly suspected that either of RFP, INH or SM was responsible for his pancytopenia. We collected another 10 cases of agranulocytosis due to anti-tuberculosis drugs in the world wide literature, and found men/women ratio 5/8 (in one case gender was not known), the duration of chemotherapy before appearance of agranulocytosis 1-3 months, no change in the lymphocyte count of the peripheral blood, and the accompanying of another allergic signs such as skin eruption, blood eosinophilia or drug-induced hepatitis in some cases, and these findings suggest that the mechanism of agranulocytosis due to anti-tuberculosis drugs was allergic in nature.

Congenital neutropenias.

The term congenital neutropenia (CN) has been used for a group of hematologic disorders characterized by severe neutropenia with absolute neutrophil counts (ANC) below 0.5 x 10(9)/L associated with increased susceptibility to bacterial infections. This group of diseases includes primary bone marrow failure syndromes with isolated neutropenias and neutropenias associated with metabolic or immunologic disorders or with a complex syndrome. To avoid confusion, we prefer using the term CN only for the most severe disorder among this group: severe neutropenia characterized by an early stage maturation arrest of myelopoiesis leading to bacterial infections from early infancy. This disease has originally been described as Kostmann syndrome with an autosomal recessive inheritance. Recent pathogenetic investigations have demonstrated that this clinical phenotype includes also autosomal dominant and sporadic cases with different point mutations in the neutrophil elastase gene in a subgroup of patients. Data on over 400 patients with CN collected by the Severe Chronic Neutropenia International Registry demonstrate that independent from the CN-subtype more than 90% of these patients respond to recombinant human granulocyte-colony stimulating factor (rHuG-CSF filgrastim, lenograstim) with ANC that can be maintained around 1.0 x 10(9)/L. Adverse events include mild splenomegaly, moderate thrombocytopenia, osteoporosis and malignant transformation into myelodysplastic syndrome/leukemia. Development of additional genetic aberrations, e.g., G-CSF-receptor gene mutations, monosomy 7 or ras mutations during the course of the disease indicate an underlying genetic instability leading to an increased risk of malignant transformation. If and how G-CSF treatment impacts on these adverse events remains unclear since there are no historical controls for comparison. Hematopoietic stem cell transplantation is still the only available treatment for patients refractory to G-CSF treatment.
