The joint application of stereotactic brain biopsy and DNA amplification methods, like the polymerase chain reaction (PCR) are diagnostic purposes that allows in approximately 24 h to clarify the viral etiology of central nervous system infections. We demonstrate PCR results from the brain biopsy of an HIV-1 patient with two cerebral lesions. Beside the neuropathological diagnosis of a B-cell non-Hodgkin lymphoma the experimental results are indicative of active transcription of cytomegalovirus (CMV) in cerebral tissue. The markedly higher amount of CMV-specific RNA found in the biopsy specimens and CSF suggest the presence of an active infection with viral replication. CT-guided stereotactic brain biopsies followed by PCR fulfill the demands of a clinician, namely to get the results as fast as possible to initiate adequate treatment.

Patients with cancer can now benefit from intensive drug dosage. Intensive drug dosage has become more effective because of the availability of better anti-emetics, hematopoietic growth factors such as granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte CSF (G-CSF), erythropoietin, etc. and improvements in hematopoietic stem cell transplantation. We have evaluated the clinical and cost effectiveness of GM-CSF in patients undergoing autologous bone marrow transplantation (AuBMT) for Hodgkin's disease. Administration of GM-CSF after AuBMT enhances myeloid and platelet recovery and is cost effective in the treatment of patients with relapsed Hodgkin's disease who received intensive chemotherapy and AuBMT. We also describe the use of various new therapeutic approaches with emphasis on clinical and cost benefit. Further work is needed to improve the route and duration of growth factor(s) infusion and the timing of the various treatments.

One hundred and twenty-eight patients with non-Hodgkin's lymphoma (NHL), Hodgkin's disease (HD), and acute lymphoblastic leukemia (ALL) previously reported from a phase III trial of rhGM-CSF or placebo following autologous bone marrow transplantation (ABMT) were investigated for the development of late toxicities. Median follow-up is 36 months. No apparent long-term deleterious effects on BM function were observed. Moreover, disease-free survival and overall survival were similar for patients on both treatment arms, arguing for the long-term safety of recombinant human granulocyte macrophage-colony-stimulating factor (rhGM-CSF). The only factors predictive for both a high risk of relapse over time and mortality were having the diagnosis of ALL and/or undergoing ABMT in resistant relapse. We attempted to identify clinical variables before BM harvest, at the time of marrow infusion, or events within the first 100 days posttransplant, which might predict speed of neutrophil recovery in the setting of placebo or rhGM-CSF administration after ABMT. Only previous exposure to agents that deplete stem cells led to a significant delay in neutrophil recovery, suggesting their avoidance in patients who may undergo ABMT. Nevertheless, even those patients benefited from rhGM-CSF. For all patients, rhGM-CSF and agents that deplete stem cells were the strongest independent predictors for neutrophil engraftment. With the increasing use of newer hematopoietic growth factors both alone and in combination, long-term follow-up is essential to confirm the same safety that we report with rhGM-CSF.

We have recently reported that the hematologic recovery of patients with non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) undergoing autologous bone marrow transplantation (BMT) is significantly faster when recombinant human interleukin-3 (rhIL-3) is combined with recombinant human granulocyte colony-stimulating factor (rhG-CSF) in comparison with patients receiving G-CSF alone. In this paper, we studied the kinetic response and concentration of BM progenitor cells of 17 patients with lymphoid malignancies submitted to autologous BMT and treated with the G-CSF/IL-3 combination. The results were compared with those of five lymphoma patients receiving the same pretransplant conditioning regimen followed by G-CSF alone. rhG-CSF was administered as a single subcutaneous (sc) injection at the dose of 5 micrograms/kg/d from day 1 after reinfusion of autologous stem cells; rhIL-3 was added from day 6 at the dose of 10 micrograms/kg/d sc (overlapping schedule). In both groups (G-CSF- and G-CSF/IL-3-treated patients), cytokine administration was discontinued when the absolute neutrophil count (ANC) was >0.5 x 10(9)/L of peripheral blood (PB) for 3 consecutive days. After treatment with the CSF combination, the percentage of marrow colony-forming units-granulocyte/macrophage (CFU-GM) and erythroid progenitors (BFU-E) in S phase of the cell cycle increased from 9.3 +/- 2% to 33.3 +/- 12% and from 14.6 +/- 3% to 35 +/- 6%, respectively (p < 0.05). Similarly, we observed an increased number of actively cycling megakaryocyte progenitors (CFU-MK and BFU-MK). Conversely, G-CSF augmented the proliferative rate of CFU-GM (22.6 +/- 0.6% compared to a baseline value of 11.5 +/- 3%; p < 0.05) but not of BFU-E, CFU-MK, or BFU-MK, and the increase of S-phase CFU-GM was significantly lower than that observed in the posttreatment samples of patients receiving IL-3 in addition to G-CSF. The frequency of hematopoietic precursors in the BM, expressed as the number of colonies formed per number of cells plated, was unchanged or slightly decreased in both groups of patients. Because of the increase in marrow cellularity, however, a significant augmentation of the absolute number of both CFU-GM (3605 +/- 712/mL BM vs. 2213 +/- 580/mL; p < 0.05) and BFU-E (4373 +/- 608/mL vs. 3027 +/- 516/mL; p < 0.05) was reported after treatment with G-CSF/IL-3 but not G-CSF alone. Similarly, administration of the cytokine combination resulted in a higher number of CD34+ cells/mL BM, and their concentration was significantly greater than that observed in the posttreatment samples of G-CSF patients. Finally, we investigated the responsiveness to CSFs, in vitro, of highly enriched CD34+ cells, collected after priming with G-CSF in vivo (i.e., after 5 days of G-CSF administration). Our results demonstrated that pretreatment with G-CSF modified the response of BM cells to subsequent stimulation with additional CSFs. The results presented in this paper indicate that in vivo administration of two cytokines increases the proliferative rate and concentration of BM progenitor cells to a greater degree than G-CSF alone. These results support the role of growth factor combinations for accelerating hematopoietic recovery after high-dose chemotherapy.

The aim of this study was to evaluate the efficacy, safety and toxicity of short-term priming with recombinant human granulocyte colony-stimulating factor (rhG-CSF) immediately after diagnosis but before combination chemotherapy (CHOP) for non-Hodgkin's lymphomas. Of fourteen patients entering the study, seven received five days subcutaneous injection of rhG-CSF (5 micrograms/kg/day) before CHOP (CSF-group), and seven were treated with CHOP alone (control group). Blood samples were studied before and on days 1-5 during rhG-CSF priming as well as twice weekly after treatment. The number of blood and bone marrow progenitors was identified by clonogenic growth day 7, 14 and 21 of GM-CFU in semisolid medium. Blood absolute neutrophil counts increased in all rhG-CSF primed patients. The expansion of marrow myelopoiesis resulted in increased myeloid:erythroid ratios, increased bone marrow cellularity and increased numbers of myeloid progenitors both in the blood as well as the marrow. Chemotherapy induced neutropenia developed on day 9-12 in all patients independent of myeloid growth factor priming. However, neutropenia appeared earlier in the cytokine primed group (P = .0038). Five patients in the CSF-group and three patients in the control group were hospitalized with neutropenic fever, and septicemia was documented in three patients in the CSF-group. RhG-CSF induced expansion of myelopoiesis immediately before combination chemotherapy mobilized sufficient number of blood progenitors for apheresis but did not result in reduction of duration and degree of neutropenia in patients with newly diagnosed non-Hodgkin's lymphoma. Although the small number of patients prevents drawing definite conclusions, this time schedule for priming should be used with caution in the future due to an increased risk of hematologic toxicity.

To evaluate the clinical effects of the administration of recombinant human granulocyte-stimulating factor (rhG-CSF) post chemotherapy for patients with advanced-staged intermediate-grade or high-grade non-Hodgkin's malignant lymphoma (NHL), we conducted this multicenter study and compared the responses between both the regimens, CHOP as a first-generation chemotherapy and ProMACE/CytaBOM as a third-generation chemotherapy, when combined with the rhG-CSF administration. In this multicenter study, where forty patients were registered, patients in both the CHOP and ProMACE/CytaBOM groups were treated with the original regimen designs without the necessity of reducing drug dosages when combined with the administration of rhG-CSF. The administration of rhG-CSF post both of the cytotoxic therapies brought about much higher rates of complete remission in both the groups (CHOP, 75 percent; ProMACE/CytaBOM, 75 percent), as compared with those of the previous study without the rhG-CSF administration. Regarding response rates according to the International prognostic factor index, the CHOP group showed a lower rate of complete remission in patients with risk factors, compared with ProMACE/CytaBOM group. This result suggested that the administration of rhG-CSF may offer one important approach for improving the first-line therapy for aggressive NHL with high risk factors.

Recombinant human interleukin-3 (rhIL-3), granulocyte-macrophage colony-stimulating factor (rhGM-CSF), and granulocyte colony-stimulating factor (rhG-CSF) enhance neutrophil recovery following autologous bone marrow transplantation (ABMT) for malignant lymphoma. Based on findings in preclinical studies, a phase I-II trial was conducted to assess the safety and efficacy of the sequential administration of rhIL-3 and rhGM-CSF after bone marrow ablative cytotoxic therapy and ABMT for patients with malignant lymphoma. Thirty-seven patients (20 with non-Hodgkin's lymphoma and 17 with Hodgkin's disease) were treated with intensive cytotoxic therapy before ABMT. Patients were treated in one of four cohorts to receive rhIL-3 (2.5 or 5.0 microg/kg/d) administered by subcutaneous injection for either 5 or 10 days following ABMT. Twenty-four hours after the last dose of rhIL-3, rhGM-CSF (250 microg/m2/d as a 2-hour intravenous infusion) administration was initiated. Sequential cytokine therapy post-ABMT resulted in fewer days of platelet and red blood cell transfusions than seen in historic controls with rhIL-3, rhGM-CSF, or rhG-CSF monotherapy. These data suggest that the sequential administration of rhIL-3 and rhGM-CSF after ABMT results in rapid recovery of multilineage hematopoiesis.

Endogenous plasma levels of granulocyte colony stimulating factor (G- CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF),IL-6 and IL-10 were measured in a total of 70 patients undergoing cytoreductive chemotherapy for treatment of acute leukaemia or non-Hodgkin's lymphomas. the diagnoses were acute myeloid leukaemia (AML; n = 30), acute lymphoblastic leukaemia (ALL;n=6), non-Hodgkin's lymphomas (NHL; n=11) and other malignant haematological disorders including myelodysplastic syndromes (n=23). After chemotherapy, plasma G-CSF was elevated (mean 5.6 ng/ml; range 1.2-10 ng/ml), and was inversely correlated with white blood cell counts (WBC) (r=-0.7, p<0.001). Occurrence of fever (T>38.0 degrees C) during severe myelosuppression (WBC<1x10(9)/1) was associated with an additional increase of G-CSF levels (P<0. (P<0.001). Plasma IL-6 correlated significantly with fever (range <1 to 1100 pg/ml, mean 130 pg/ml; r=0.5, P<0.001) but revealed only a weak association with WBC or platelet counts. In patients treated with recombinant G-CSF (n = 9), an association between IL-6 and fever was still observed after chemotherapy. During the nonfebrile status (total n = 242; AML n = 124), IL-6 levels remained <9 pg/ml in 90% of cases, whereas G-CSF increased with leucopenia (r = -0.72;P<0.001). In contrast, endogenous GM-CSF remained normal and IL-10 showed only a slight increase (21% of samples; maximum 22 pg/ml) in severe leucopenia. In particular, IL-10 levels did not correlate with G-CSF or IL-6 levels. We conclude that systemic release of G-CSF and IL-6 is obviously nit abrogated by cytoreductive chemotherapy in acute leukaemia and NHL may add to the therapeutic efficacy of recombinant cytokines. Also, plasma levels of G-, GM-CSF or IL-6 appear to be regulated by separate mechanisms.

Granulocyte colony-stimulating factor (G-CSF) as a single agent is increasingly used for the mobilization of peripheral blood progenitor cells (PBPCs) for stem cell transplantation. In patients with perturbed hematopoiesis the mobilizing capacity of G-CSF alone may be inadequate. We have shown in rhesus monkeys that interleukin-3 (IL-3) pretreatment markedly potentiated the increase in PBPC numbers by subsequent administration of granulocyte/macrophage-CSF (GM-CSF). Here we studied the effect of IL-3 pretreatment on G-CSF-induced mobilization of PBPCs in 6 patients with Hodgkin's disease (n = 5) or non-Hodgkin's lymphoma (n = 1) who had low progenitor cell numbers because of previous chemotherapy. Patients were treated in cycle 1 with G-CSF at a dose of 5 microgram/kg/d for 5 days and, after a treatment-free interval, received cycle 2 consisting of 5 microgram/kg/d of IL-3 for 7 days followed by G-CSF again at a dose of 5 microgram/kg/d for 5 days. G-CSF alone increased the mean number of circulating colony-forming units-GM (CFU-GM) by 21-fold, the number of burst-forming units-erythroid (BFU-E) by 9-fold, and the number of CFU-mix by 24-fold over pretreatment values. Treatment with 5 microgram/kg/d of IL-3 for 7 days did not mobilize by itself but significantly potentiated G-CSF-induced mobilization of all progenitor cell types leading to a 56-, 15-, and 46-fold increase over baseline of CFU-GM, BFU-E, and CFU-mix numbers, respectively. In 2 patients in whom leukapheresis was performed after G-CSF alone the target number of 2 x 10(6)/kg CD34+ cells was not reached. However, leukapheresis after the IL-3/G-CSF combination obtained > or =2 x 10(6)/kg CD34+ cells in 3 of 6 patients, including both patients who had inadequate collection after G-CSF alone. In one patient adequate function of mobilized progenitors could be shown by the demonstration of rapid trilineage engraftment after infusion of progenitors after myeloablative chemotherapy. Seven-day pretreatment with IL-3 may be a useful mean to augment mobilization of circulating progenitors by G-CSF. The combination of IL-3 and G-CSF seems to allow the procurement of sufficient numbers of PBPCs in some patients who cannot be mobilized adequately by G-CSF alone.

The study includes 61 cases which were subjected to ultrasound (US) guided fine needle aspiration cytology (FNAC) to find out the utility of this technique in the diagnosis of pancreatic lesions. Age of the patients ranged from 23 to 85 years with a median of 50 years. Male to female ratio was 36:25. One or more clinical diagnoses were offered in 16 and in 9 of these, the disease was related to pancreas. Subsequent to US, the lesions were localized to pancreas in 57 and the nature of pathology in the pancreatic lesion could be diagnosed in 31. By FNAC, 31 cases (50.8%) were diagnosed to have pancreatic malignancy which included adenocarcinoma (23 cases), papillary cystic tumour (1), muco-epidermoid carcinoma (1), acinic cell carcinoma (1), islet cell tumor (1), and non Hodgkin lymphoma (4). FNAC of liver in 2 cases and retroperitoneal lymph node in a case of pancreatic adenocarcinoma revealed metastasis. During follow up, 1 case of non Hodgkin's lymphoma showed CSF involvement. Three cases (4.9%) were suspected to have epithelial malignancy of which one was confirmed as an adenocarcinoma following surgery and histology. Four (6.6%) were benign lesions which included nonspecific inflammation (2 cases), tuberculous pancreatitis (1) and pseudopancreatic cyst (1). The remaining 23 cases (37.7%) had normal or inadequate cytology. Of these, FNAC of liver showed metastasis in 2 cases and one case each were diagnosed as adenocarcinoma and pseudopancreatic cyst respectively following surgery. None of the patients had any complication following FNAC. We recommend US guided FNAC to be routinely used for diagnosis of pancreatic lesion.
