A sedimentation technique for cytologic study of CSF was compared with the standard cytocentrifugation method. Seventy-five samples from 37 children with leukemia and non-Hodgkin's lymphoma were processed by both methods. Total yield of cells and cytomorphology with differentials were analyzed. The techniques are comparable and both allow good cytologic study of the CSF even with very low cell counts/mm3. The sedimentation method can be used as an alternative, especially if a cytocentrifuge is not available. When both methods are used, the possibility of negative cell yield is decreased.

We examined the effects of recombinant human granulocyte colony-stimulating factor (rG-CSF) on neutropenia induced by chemotherapy in 10 patients with non-Hodgkin's lymphoma (NHL). The numbers of peripheral blood hematopoietic progenitors were also evaluated before and after administration of rG-CSF. Six patients received an administration of 2 micrograms/kg/body weight of rG-CSF subcutaneously for 14 days after 2nd chemotherapy. Four patients received intravenous infusion of rG-CSF (300 micrograms/body/day) for 4 days from nadir state after chemotherapy. Administration of rG-CSF from the termination of chemotherapy, markedly shortend the period of bone marrow hypoplasia induced by chemotherapy. On the other hand, administration of rhG-CSF from nadir state after chemotherapy have accelerated the recovery of neutrophil counts. In addition, this type of therapy induced 26 to 60 folds increase of peripheral blood hematopoietic progenitors. These results demonstrate the validity of administration of rhG-CSF not only in the chemotherapy of NHL, but also in peripheral blood stem cell transplantation (PBSCT).

Seven children with advanced neuroblastoma and non-Hodgkin's lymphoma were treated with myeloablative chemoradiotherapy (180 mg/m2 melphalan plus 12 Gy fractionated total body irradiation), followed by autotransplantation of peripheral blood stem cells (PBSC). Sufficient PBSC to restore bone marrow function were collected by a small number of leukaphereses during haematopoietic recovery after chemotherapy and recombinant human granulocyte colony-stimulating factor (rhG-CSF). Furthermore, rapid recovery of neutrophils was found in all patients by the administration of rhG-CSF following transplantation: median 10 d (range 8-12) to attain more than 0.5 x 10(9)/l neutrophils, and 27 d (range 14-73) to attain more than 50 x 10(9)/l platelets, respectively. Haematopoietic reconstitution has been maintained throughout the follow-up period (median 15 months; range, 6-22). Peripheral blood stem cells mobilized by chemotherapy and rhG-CSF can induce complete haematopoietic reconstitution after myeloablative chemoradiotherapy.

Recombinant human granulocyte colony-stimulating factor (rhG-CSF) was given in combination with chemotherapy in elderly patients (greater than or equal to 65 years old) with malignant lymphoma, and the therapeutic efficacy and the incidence of side effects were determined. The subjects consisted of 5 males and 8 females with a median age of 74 years. One patient had Hodgkin's disease and 12 had non-Hodgkin's lymphoma. Regarding lymphoma stage, 2 were in stage II, 3 were in stage III, and 8 were in stage IV. The chemotherapy used was COP-BLAM in 8 patients, COP-BLAM III in 2, IMV-triple P in 2, and ACVP-16 in 1. Treatment with rhG-CSF (1.5 micrograms/kg/day) was commenced during or after the 2nd course of chemotherapy when the neutrophil count dropped to greater than or equal to 1,000/microliters, and was continued until the recovery of either the neutrophil or leukocyte count to 10,000/microliters or 20,000/microliters, respectively. The neutrophil nadir in the non-G-CSF group was 367.3 +/- 231.6/microliters. In the G-CSF group it was 754.6 +/- 116.4/microliters for the second course, with the difference between the 2 groups being significant (p less than or equal to 0.05). Also, the following time periods were significantly shorter in the G-CSF group than the non-G-CSF group: 1) the duration of a neutrophil count less than 1,000/microliters, 2) the duration of fever (greater than or equal to 37.5 degrees C), and 3) the time to recovery from the neutrophil nadir.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied nine patients with a subacute onset of a pancerebellar syndrome. Six had known cancer (three small-cell carcinoma of the lung [SCLC], one metastatic small-cell carcinoma, one small-cell carcinoma of the prostate, and one non-Hodgkin's lymphoma). Six of eight who had neurophysiologic testing, including the three patients without detectable cancer, had coexistent Lambert-Eaton myasthenic syndrome (LEMS). In two of the patients, LEMS was discovered only by neurophysiologic testing. We looked for anti-Purkinje cell autoantibodies in all patient's sera and in four patients' CSF. We also looked for autoantibodies to voltage-gated calcium channels (VGCCs) in seven patients' sera and two patients' CSF, using the 125I-omega-conotoxin radioimmunoassay. We were unable to detect anti-Purkinje cell autoantibodies in any patients' serum or CSF. However, there were raised titers of anti-VGCC autoantibodies in five of seven patients' serum, including one patient with SCLC who did not have LEMS, and in the CSF of one of two patients. We conclude that the frequency of presentation of a pancerebellar syndrome with LEMS is higher than expected by chance and is usually associated with cancer. In some of these patients, LEMS may be clinically occult. The presence of LEMS and raised titers of anti-VGCC autoantibodies in some patients with subacute cerebellar degeneration is suggestive of an autoimmune etiology even though anti-Purkinje cell antibodies could not be detected. Anti-VGCC autoantibodies are not confined to LEMS. They may be found at high titer in CSF as well as serum.

Infections during granulocytopenia are major complications of autologous bone marrow transplantation (ABMT). Since recombinant human granulocyte-macrophage colony-stimulating factor (rhuGM-CSF) has proved to accelerate bone marrow recovery after cytostatic chemotherapy, we studied its effects on hematopoietic regeneration and on infectious complications after total body irradiation (TBI) and high-dose chemotherapy followed by ABMT. Eighty-one patients with acute lymphoblastic leukemia (ALL) in complete remission (CR) or with non-Hodgkin's lymphoma (NHL) in CR or partial remission were randomized in a double-blind, placebo-controlled trial. They received either rhuGM-CSF 250 micrograms/m2 (Escherichia coli-derived) daily by continuous infusion after ABMT, or placebo. Treatment was continued until the neutrophil counts reached greater than 500/microL for 1 week. The maximum treatment duration was 30 days. Thirty-nine patients in the rhuGM-CSF group and 40 patients in the placebo group were evaluable. The median time needed to reach a neutrophil count of 500/microL was 15 days with rhuGM-CSF and 28 days with placebo (P = .0001). Bacterial infections occurred in 14 (35.9%) of the patients with rhuGM-CSF and in 25 (62.5%) of the patients given the placebo (P = .024). Nine of the 14 bacterial infections in the rhuGM-CSF group and 20 of the 25 infections in the placebo group were diagnosed within the first 10 days after ABMT. Capillary leakage and a reversible fluid retention were seen in five of the rhuGM-CSF-treated patients. Patients treated with rhuGM-CSF had lower serum protein and albumin levels than patients in the placebo group. There was no statistically relevant difference in overall survival between the two groups (P = .47). Relapse occurred in 14 (34%) patients with rhuGM-CSF and in 18 (45%) patients with placebo. We conclude that continuous infusion of rhuGM-CSF after ABMT accelerates the regeneration of granulocytes and reduces the number of bacterial infections.

Recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) derived from E. coli was administered to 24 previously untreated patients with non-Hodgkin's lymphoma following the first cycle of CHOP chemotherapy. Four dose levels were examined, 1.5, 3.0, 5.5 and 11 micrograms/kg and patients were randomized to receive the drug either once or twice daily subcutaneously (s.c.). During rhGM-CSF treatment, the leucocyte counts increased up to 3-4 fold in 20/24 patients, reaching a peak 24-48 (mean 35) hours after initiation of rhGM-CSF. The leukopenic period in cycle one of the CHOP chemotherapy with rhGM-CSF, was shorter than after the course of chemotherapy without rhGM-CSF and also shorter when compared to cycle one of CHOP in the 127 historical controls (p < 0.05 and p < 0.001 respectively). Similar results were observed for neutrophil counts. No effect was seen on platelet counts at nadir but a significant, although moderate increase occurred in the recovery period on days 15 and 22 when compared to control cycles and historical controls. When dose levels were compared, there was only a trend to higher WBC counts at the higher dose groups (5.5 and 11 micrograms/kg) when compared to the two lower dose groups (1.5 and 3.0 micrograms/kg). In the overall evaluation there was no statistical significant difference in results between patients treated s.c. once daily versus twice daily. However when only the two highest dose levels (5.5 + 11 micrograms/kg) were compared, s.c. administration of rhGM-CSF twice daily led to higher leucocyte counts than once daily in the recovery period on day 15 (p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Peripheral blood cells of a patient with diffuse large cell non-Hodgkin's lymphoma presenting with hypereosinophilia were used to establish an EBV negative lymphoma cell line termed OCI-Ly17. Cells of the line stained positive for CD2 and CD5 determinants and demonstrated rearrangement of the T-cell receptor beta chain. The immunoglobulin heavy chain gene was found to be in germ line configuration. Northern blot studies using probes for IL-1 alpha, IL-3, IL-4, IL-5, IL-6, and GM-CSF showed message for IL-5 and IL-6. Supernatants of the cell line were evaluated on normal non-adherent, E-rosette depleted bone marrow cells to determine the presence of growth promoting activities for clonogenic eosinophilic progenitors. Eosinophilic colonies were observed. Their frequency depended upon the amount of supernatant added to the cultures. The growth promoting activity in the supernatant was reduced in a dose dependent manner by preincubation with increasing concentrations of anti-IL-5 antibodies. The supernatants of the cell line were also tested on the IL-6 sensitive human myeloma line OCI-My4 and myeloma colonies grew in response. This stimulatory activity within the supernatant was neutralized by addition of increasing concentrations of anti-IL-6 antibodies. Although producing IL-5 and IL-6 constitutively, the lymphoma line did not increase proliferation in response to either interleukin, nor did it show a reduced proliferative rate when antibodies to IL-5 or IL-6 were added to the cultures.

The toxicity of autologous bone marrow transplantation (ABMT) is correlated to neutropenia. Although recombinant human granulocyte-macrophage colony-stimulating factor (rhu GM-CSF) seems to hold promise in accelerating neutrophil recovery, few analyses from randomized studies are presently available. Ninety-one patients with non-Hodgkin's lymphoma receiving high-dose ablative chemotherapy followed by ABMT with unpurged or purged marrow were included in a randomized, double-blind, placebo-controlled trial. Forty-four patients received 250 micrograms rhu GM-CSF (Escherichia coli)/m2 and 47 patients received placebo. Treatment was administered daily as continuous infusion from day of ABMT until the absolute neutrophil count (ANC) reached 0.5 x 10(9)/L for 7 days or until day 30, whichever was first. With rhu GM-CSF, 50% of the patients reached an ANC count greater than 0.5 x 10(9)/L at day 14 as opposed to day 21 with placebo (P less than .0001). Patients transplanted with marrow purged by mafosfamide also recovered earlier when treated with rhu GM-CSF (16 v 20.5 days, P = .013). The hospitalization duration was shorter in the rhu GM-CSF group (median, 23 v 28 days, P less than .05). No difference was observed in fever, number of infections, and antibiotic administration between the two groups. The major adverse event ascribed to rhu GM-CSF was a capillary leak syndrome in three patients graded as severe in two patients, moderate in one, and reversible in all three patients. In addition, one patient in the rhu GM-CSF group died suddenly with no explanation. In long term follow-up, the relapse rate was identical in both groups and there was no significant difference in the number of deaths at 1 year (12 with rhu GM-CSF v 9 with placebo), although deaths seemed to occur slightly earlier in the rhu GM-CSF group. We conclude that after ABMT with purged or unpurged marrow, rhu GM-CSF (E coli) significantly reduces neutropenia duration and hospitalization stay. A positive causative relation between the study drug and/or its mode of application with an increased toxicity as compared with GM-CSF from other sources and/or other modes of application cannot be deduced from the experiences in this study. Additional randomized trials would be necessary for an appropriate answer.

To determine the potential impact of recombinant human erythropoietin (EPO) therapy in patients undergoing autologous bone marrow transplantation (BMT) and colony-stimulating factor therapy, we assayed endogenous serum EPO levels and noted blood transfusion requirements in relapsed non-Hodgkin's lymphoma patients treated with high-dose chemo-radiation therapy and autologous BMT. Hematocrit and reticulocyte counts were determined daily, and hematocrit was maintained in the 25-30% range by transfusion according to criteria established by our hospital transfusion committee. EPO levels were measured by radioimmunoassay and were determined at baseline, throughout therapy, and 2 and 3 months after BMT. Serum EPO levels increased more than 25-fold above baseline in most subjects after initiating chemoradiation therapy. No correlation was noted between serum EPO and hematocrit, reticulocyte count or serum creatinine. Total red blood cell units transfused ranged from 4 to 15 (mean 7.7). Mean total donor exposures (red blood cell plus platelet units transfused) were 83.6 units (range 16-175). Serum EPO levels increased early in the course of preparation for autologous BMT and remained elevated for at least 2-3 weeks thereafter although at a lower level. Red blood cell transfusions were required despite very high EPO levels after BMT. Red cell transfusions, moreover, accounted for only 9.2% (69 of 746) of total donor exposures and only 5.8% (42 of 746) of donor exposures during the interval when pharmacologic doses of erythropoietin might be of benefit. In contrast to the potential benefit of colony-stimulating factors such as G-CSF and GM-CSF in BMT, our study suggests limited value for erythropoietin therapy in this setting.
