The availability of rh GM-CSF has allowed the in vivo treatment of patients with cytopenia. Therefore a phase I/II trial was initiated to study the effect of rh GM-CSF in patients with myelodysplastic syndromes who were not eligible for other kinds of therapy. rh GM-CSF has been tested in 10 patients in doses from 15 micrograms/m2 to 150 micrograms/m2 given intravenously over 8 hours for a cycle of 7 days followed by an interval of 14 days and a second 7-day treatment course. A dose dependent increase in leukocyte count was observed in 9 out of 10 patients. No change in reticulocyte numbers was seen and only one patient experienced an increase in platelet count. Toxicity mainly consisted of mild local phlebitis at the site of infusion and sternal pain after bolus injection. An increase in blast cell counts in some patients necessitated the start of low dose Ara-C therapy.

We have investigated the role, if any, of inflammatory cytokines in herniated tissues in the development of sciatic pain resulting from lumbar disc herniation. In histological examination of herniated discs, granulation tissue was observed in 16.7% of protrusion type herniation,69.6% of extrusion type, and in 77.9% of sequestration type herniation. In homogenates of the herniated tissues. IL-1 alpha, IL-1 beta, IL-6, TNF-alpha and GM-CSF were detected in all types of lumbar disc herniation. Cells producing these cytokines were detected in the tissues after immunohistological staining In the protrusion type, cells producing these cytokines were detected in chondrocytes, and in extrusion or sequestration type, most of these cytokines producing cells were histiocytes or fibroblasts which constituted granulation tissue. The herniated tissue in culture produced these cytokines and prostaglandin E2, which ws remarkable decreased by the addition of betamethasone. The production of prostaglandin E2 in vitro was dramatically increased by the addition of IL-1 alpha and decreased by the addition of TNF-alpha. Furthermore, IL-1 alpha receptors and TNF-alpha were detected in cultured herniated tissue using radioimmunoassay techniques. The affinity of the IL-1-alpha receptor was higher than that of the TNF-alpha receptor. Based on these findings, it was suggested that inflammatory cytokines, such as IL-1 alpha, are produced in herniated tissue, which increased prostaglandin E2 production and caused in sciatic pain.

This investigation is devoted to the study of the time-course of a cytokines panel (IL-4, IL-6, IFN-gamma, GM-CSF) in plasma samples from migraine patients. The data obtained during challenged migraine crises was compared to the baseline values. Time-data series analysis showed a fall after a challenge test for IL-4 and IL-6 plasma levels and an opposite trend for gamma-IFN and GM-CSF levels. The implication of this phenomenon in dietary migraine is not readily evident. There may possibly be an activation of this cytokine network together with the well-known impairment in the neuropeptidergic system, considering the close links between interleukins and other cytokines and the neuro-mediators of pain, such as histamine and 5-HT.

Authors report their first experiences with the application of granulocyte-macrophage colony stimulating factor in 12 pediatric cancer patients (14 cases). The drug was given in a 5 micrograms/kg single daily dose subcutaneously. Patients were divided into three main indication groups: 1. Severe neutropenia (white blood cell count < 1.0 G/l) and sepsis (6 patients); 2. Prolonged neutropenia (white blood cell count: 1.0-2.0 G/l) and delay in treatment (3 patients); 3. Dose-escalation of chemotherapy in therapy-resistant cases (4 patients). Authors report that in all cases a substantial raise in white blood cell count could be achieved after 5-6 days of granulocyte-macrophage colony stimulating factor treatment. No side effects were detected except of a moderate local pain at the site of the injection. Authors suggest that in the above described dose and way of administration granulocyte-macrophage colony stimulating factor can be an effective agent in the treatment of chemotherapy-induced neutropenia in paediatric oncology.

The author presents part II of his review on the treatment of refractory myeloma. Treatment with large doses of melphalane, 140 mg/m2, was associated with a high death rate and therefore it is used nowadays only in combination with autologous transplantation or treatment with leucocytic growth factors (GM-CSF and G-CSF). Medium doses of melphalane (25 mg/m2 to 70 mg/m2) are tolerated better and are one of the possible approaches. Another possible therapeutic procedure is whole-body irradiation. The advantage of extensive irradiation is rapid regression of pain. Interferon-alpha achieves a therapeutic response in some 20% of refractory patients. Finally the author presents some data on transplantation of bone marrow in patients with multiple myeloma.

We studied the effects of escalating doses of recombinant human IL-1 beta in patients receiving high-dose chemotherapy and ABMT for metastatic breast cancer or malignant melanoma. Sixteen patients received IL-1 beta, 4 to 32 ng/kg/day administered subcutaneously for 7 days beginning 3 h after bone marrow infusion. Three patients at the highest dose level also received G-CSF following completion of IL-1 beta. All patients completed the 7 days of therapy. The majority of patients experienced chills and fever following one or more injections, and seven had severe pain at the injection site. There was one episode of hypotension and one episode of transient confusion at the highest dose level; other significant toxicity was not identified. Recovery of neutrophils to > 0.5 x 10(9)l and platelet transfusion independence occurred at a median of 23 and 22 days, respectively, which was comparable to historical controls. The mean number of bone marrow colony-forming unit granulocyte-macrophage (CFU-GM) per 10(5) mononuclear cells on day +21 post-ABMT was more than twice that of control patients or patients receiving G-CSF or GM-CSF. A linear correlation was found between the dose of IL-1 beta and endogenous concentrations of several cytokines. These patients also displayed significantly higher concentrations of endogenous G-CSF compared to historical controls receiving GM-CSF. While IL-1 beta was moderately toxic and had no effect on recovery of peripheral blood counts after ABMT, the increased number of bone marrow CFU-GM suggests that the addition of G- or GM-CSF to a short course of IL-1 beta may accelerate hematologic recovery.

The class I IgG receptor (Fc gamma RI or CD64 receptor), which is present on key cytotoxic effector cells, has been shown to initiate the destruction of tumor cells in vitro and has been hypothesized to play a role in the destruction of antibody-coated cells such as platelets in idiopathic thrombocytopenia purpura (ITP). This overview summarizes the clinical experience with CD64-directed immunotherapy in cancer patients with the bispecific antibodies MDX-447 [humanized Fab anti-CD64 x humanized Fab anti-(epidermal growth factor receptor, EGFR)] and MDX-H210 (humanized Fab anti-DC64 x Fab anti-HER2/neu), and with the anti-CD64 monoclonal antibody (mAB) MDX-33 (H22) in the modulation of monocyte CD64 in vivo. In an ongoing phase I/II open-label trial with progressive dose escalation (1-15 mg/m2), patients with treatment refractory EGFR-positive cancers (renal cell carcinoma (RCC), head and neck, bladder, ovarian, prostate cancer and skin cancer) are treated weekly with intravenous MDX-447, with and without granulocyte-colony-stimulating factor (G-CSF). MDX-447 has been found to be immunologically active at all doses, binding to circulating monocytes and neutrophils (when given with G-CSF), causing monocytopenia and stimulating increases in circulating plasma cytokines. MDX-447 is well tolerated, the primary toxicities being fever, chills, blood pressure lability, and pain/ myalgias. Of 36 patients evaluable for response, 9 have experienced stable disease of 3-6 month's duration. The optimal dose and the maximal tolerated dose (MTD) have yet to be defined; dose escalation continues to define better the dose, toxicity, and the potential therapeutic role of this bispecific antibody. Three MDX-H210 phase II trials are currently in progress, all using the intravenous dose of 15 mg/m2 given with granulocyte/macrophage (GM-CSF). These consist of one trial each in the treatment of RCC patients, patients with prostate cancer, and colorectal cancer patients, all of whom have failed standard therapy. At the time of writing, 11 patients have been treated in these phase II trials. Four patients have demonstrated antitumor effects. Patients demonstrating responses include 2 with RCC and 2 with prostate cancer. One RCC patient has had a 54% reduction in size of a hepatic metastatic lesion and the other has had a 49% decrease in the size of a lung metastasis with simultaneous clearing of other non-measurable lung lesions. Regarding the two patients with prostate cancer, one has had a 90% reduction in serum prostate-specific antigen (PSA; 118-11 ng/ml), which has persisted for several months; the other patient with prostate has had a 70% reduction of serum PSA (872 ng/ml to 208 ng/ml) within the first month of treatment. Both patients have also demonstrated symptomatic improvement. In a completed phase I and in ongoing phase I/II clinical trials, patients with treatment-refractory HER2/neu positive cancers (breast, ovarian, colorectal, prostate) have been treated with MDX-H210, which has been given alone and in conjunction with G-CSF, GM-CSF, and interferon gamma (IFN gamma). These trials have been open-label, progressive dose-escalation (0.35-135 mg/m2) studies in which single, and more often, multiple weekly doses have been administered. MDX-H210 has been well tolerated, with untoward effects being primarily mild-to-moderate flu-like symptoms. The MTD has not yet been defined. MDX-H210 is immunologically active, binding to circulating monocytes, causing monocytopenia, as well as stimulating increases in plasma cytokine levels. Furthermore, some patients have evidence of active antitumor immunity following treatment with MDX-210. Antitumor effects have been seen in response to MDX-H210 administration; these include 1 partial, 2 minor, and 1 mixed tumor response; 15 protocol-defined stable disease responses have occurred.

This study compared two recombinant human (rh) hematopoietic growth factors in healthy volunteers for stem cell stimulation. Granulocyte colony-stimulating factor (G-CSF, n=9) or granulocyte-macrophage colony-stimulating factor (GM-CSF, n=8) was given subcutaneously for 5 days (5 microg/kg/day). Controls (n=5) received no growth factor. Laboratory parameters and side effects were monitored for 8 days. Within 24 h, both cytokines led to a rapid increase of leukocytes, the majority of which were granulocytes. Compared with the controls (n=5), the increase on day 5 in the G-CSF/GM-CSF groups was 37-/10-fold (CD34+ cells), 5.2-/2.4-fold (leukocytes), 7.2-/3.0-fold (granulocytes), 7.4-/4.4-fold (monocytes), 1.7-/1.1-fold (lymphocytes), 9.8-/2.7-fold (basophils), 2.3-/9.6-fold (eosinophils), and 1.9-/1.6-fold (reticulocytes). The mobilization of myeloblasts, promyelocytes, myelocytes, and metamyelocytes coincided with the pronounced increase of CD34 + PBPC observed on day 4. Serum levels of uric acid (UA) and lactic dehydrogenase (LDH) increased under G-CSF, and platelets decreased after G-CSF discontinuation. Rash at the injection site occurred in 50% of the GM-CSF-treated volunteers. Seven volunteers in the GM-CSF group and six in the G-CSF cohort complained of flu-like symptoms, including musculoskeletal pain. We conclude that, in terms of tolerance and mobilization of CD34+ cells and leukocytes, G-CSF is superior to GM-CSF, but higher levels of UA and LDH and late decrease in platelets make monitoring of these parameters necessary.

Seventeen patients stung by Tityus serrulatus scorpion were classified as mild (pain at the site of the sting, n = 6), moderate (local pain and one of the following manifestations: vomiting, psychomotor agitation, prostration, sweating, tachypnea, tachycardia and mild arterial hypertension, n = 10) and severe cases (equal moderate cases plus cardiac failure, pulmonary edema and shock, n = 1). Venous blood was sampled for biochemical and hematological analysis and for IL-1alpha, IL-6, IL-10, TNF-alpha, IFN-gamma and GM-CSF ELISAs at the time of hospital admission, 6 h (moderate and severe cases), and 12, 18, 36 and 72 h (severe case) later. Ten age-matched healthy volunteers were used as control. Increased serum levels of IL-1alpha was noticed in all patients, high levels of IL-6, IFN-gamma and GM-CSF were observed only in a patient with severe envenomation. Our data suggest that a systemic inflammatory response-like syndrome is triggered during severe envenomation caused by T. serrulatus sting and that release of cytokines may be involved in this response.

The management of mucositis is the subject of many controversies, and the optimal treatment is still not known. Several evaluation scoring systems have been described, but no one of these is appropriate to all clinical situations: a simple scale such as that devised by the WHO can be used routinely, and more sophisticated ones can be implemented by trained experimenters working in research. We have considered the impact of each of the treatments currently available on each stage of mucositis. In attempts at prevention, self-care, in the sense of oral hygiene, must remain atraumatic. It is probably advisable to differentiate patients with good previous oral care, in whom tooth brushing is beneficial, from others, in whom the risk of hemorrhage and infection excludes any brushing. Before the dosage of chemotherapy is reduced, the curative or palliative intent of the strategy must be carefully evaluated. In the vascular phase protection of the proliferating cells is attempted by means of vasoconstriction (cryotherapy), cytoprotection (prostaglandin E2 and other antioxidants) or epithelial cell-inhibiting factors such as TGF-B3. Treatments applied in the epithelial phase are directed at increasing the cell proliferation to accelerate epithelial restoration by sucralfate and several growth factors: hematopoietic GF, which has demonstrated a direct effect on the mucosa (GM-CSF), or epithelial growth factors such as keratinocyte GF. In the ulcerative and bacteriological phase attempts are made to attenuate sepsis by means of antiseptics (chlorhexidine), amphotericin B and antiviral agents or antibiotic lozenges. In the healing phase application of the low-energy helium-neon laser has demonstrably been followed by a later time of onset, less pronounced peak severity and shorter duration of oral mucositis. After cancer treatment, oral hygiene, inhibition of oral flora, and pain relief are the main goals. Physiopathogen-specific treatment is the next step, with the emphasis on the inhibition of epithelial cell proliferation during drug exposure and facilitation of epithelial maturation and healing.
