Bacterially synthesized recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) is an agent with therapeutic potential for neutropenic states, but even at doses below the maximal tolerated dose adverse effects occur during short courses of administration. We have recognized a syndrome of hypoxia and hypotension that follows the first but not subsequent doses of rhGM-CSF. Thirteen of 42 patients receiving rhGM-CSF in phase I studies and 4 of 6 patients in a phase II study developed a reaction that occurred after the first dose of 24 of 78 cycles of rhGM-CSF therapy. The reaction was characterized by flushing (16 of 24), tachycardia (16 of 24), hypotension (14 of 24), musculoskeletal pain (13 of 24), dyspnea (12 of 24), nausea and vomiting (11 of 24), rigors (5 of 24), involuntary leg spasms (3 of 24), and syncope (3 of 24). The reaction did not occur after any of more than 600 second and subsequent consecutive rhGM-CSF doses. Oxygen saturation decreased during first-dose reactions by 8% +/- 4% as compared with 3% +/- 1% on first days without reactions (P less than .001) and 2% +/- 1% on subsequent days (P less than .001). Pulmonary dysfunction was characterized by hypoxemia (59 +/- 9 mm Hg, mean +/- SD) that was fully correctable with supplementary oxygen, decreased single-breath carbon monoxide diffusion capacity, and increased alveolar-arterial oxygen gradients (25 +/- 6 to 60 +/- 4 mm Hg, mean +/- SD), but no significant abnormalities on chest roentgenogram or lung perfusion scan. Factors predisposing to reactions were rhGM-CSF dose greater than or equal to 3 micrograms/kg (P less than .01), intravenous (IV) rather than subcutaneous (SC) administration (P less than .05), occurrence of a reaction after the first dose of a previous cycle of rhGM-CSF therapy (P less than .01), and for patients receiving 15 micrograms/kg/d by SC bolus, the presence of lung cancer (P less than .05). Administration of 15 micrograms/kg/d rhGM-CSF by 24-hour SC infusion rather than SC bolus resulted in a delayed onset of reaction from 30 +/- 8 minutes to 240 +/- 190 minutes (mean +/- SD, P less than .001), and a slower rate of initial transient decrease in neutrophil levels and a more prolonged duration of transient leukopenia. The time of onset of reactions correlated with the rate of rise of rhGM-CSF levels.(ABSTRACT TRUNCATED AT 400 WORDS)

We investigated the effect of oral aspirin and ibuprofen on the ex vivo synthesis of interleukin-1 alpha (IL-1 alpha), IL-1 beta, IL-2, IL-6, tumour necrosis factor-alpha (TNF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) by stimulated peripheral blood mononuclear cells (PBMC) from healthy volunteers. Seven volunteers took 325 mg of aspirin daily for 14 days. Three weeks after ending aspirin medication, ex vivo IL-1 beta and TNF synthesis induced by exogenous IL-1 alpha was elevated threefold compared to the pre-aspirin value (P = 0.01 and P = 0.005, respectively). Using lipopolysaccharide (LPS) as a stimulus, no influence of oral aspirin was observed. The increase in cytokine synthesis did not parallel decreased synthesis of prostaglandin E2 (PGE2). Seven weeks after discontinuation of aspirin, cytokine and PGE-2 production returned to pre-aspirin levels. Another seven volunteers took 200 mg of ibuprofen daily for 12 days. Again, there was no effect on LPS- or Staphylococcus epidermidis-induced cytokine synthesis. However, IL-1 alpha-induced synthesis of IL-1 beta was elevated to a mean individual increase of 538% (P < 0.001) and synthesis of TNF was elevated to 270% (P < 0.001) at the end of ibuprofen medication and 2 weeks after discontinuation of ibuprofen. There were parallel increases in PGE2 and both returned to their pre-ibuprofen levels 5 weeks after stopping. Although inhibitors of cyclo-oxygenase blunt PGE2-mediated symptoms such as fever and pain, we conclude that short term use of either aspirin or ibuprofen results in a 'rebound' increase in cytokine-induced cytokine synthesis that is not observed in LPS-induced cytokines.

We performed a phase Ia/Ib trial of chimeric anti-GD2 monoclonal antibody 14.18 (ch14.18) in combination with recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) to determine the maximum tolerated dose as well as immunologic and biologic responses to the regimen. Sixteen patients with metastatic malignant melanoma received escalating doses of ch14.18 (15-60 mg/m2) administered intravenously for 4 h on day 1. Twenty-four hours later, subcutaneous injections of rhGM-CSF were administered daily for a total of 14 days. Significant side effects were related to ch14.18 infusion and consisted of moderate to severe abdominal and/or extremity pain, blood pressure changes, headache, nausea, diarrhea, peripheral nerve dysesthesias, myalgias, and weakness. Dose-limiting toxicity was observed at 60 mg/m2 and consisted of severe hypertension, hypotension, and atrial fibrillation in one patient each, respectively. Significant increases in white blood cell count, granulocyte count, eosinophil count, and monocyte count occurred after rhGM-CSF treatment. Significant enhancement of in vitro and in vivo monocyte and neutrophil tumoricidal activity and antibody-dependent cellular cytotoxicity along with significant elevations in C-reactive protein and neopterin were observed. Despite these immunological and biological changes, no antitumor activity was seen. In short, the combination of ch14.18 and rhGM-CSF resulted in toxicity similar to that observed with ch14.18 alone without improvement in tumor response.

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.

Oral mucositis is a major dose-limiting toxic effect of intensive cancer chemotherapy. Oral complications may lead to dose reduction or delay in further cancer treatment. Mucositis can be caused directly by cytotoxic effects and indirectly by sustained neutropenia after cytostatic therapy. An impaired mucosal barrier predisposes to life-threatening septic complications during aplasia. The prevalence of an oral focus in febrile neutropenia has been reported in up to 30% of cases and also reduces quality of life. The basic strategies aim at pain relief and prevention of bacterial and fungal infectious complications. However, no effective causal prophylaxis or treatment of oral mucositis is widely accepted. The introduction of cytokines, eg granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) for oral mucositis may be particularly effective and offer a new and hopeful approach. At present, the optimal growth factor, best schedule, effective dosage and best mode of application is not known.

Oral recurrent aphthous ulceration (RAU) is a well-recognized complication in patients infected with human immunodeficiency virus. RAU can be progressive and destructive, causing dysphagia and secondary malnutrition. The aetiology of RAU remains unknown, and its response to available treatments is often unsatisfactory. We describe three patients with advanced AIDS who suffered from extensive RAU which failed to respond to several treatments, including topical viscous lidocaine and topical and systemic glucocorticoids. Owing to difficulties in using thalidomide (two patients had neurological conditions which precluded thalidomide use), all three patients were treated with an oral solution containing recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF, 400 microg in 5% glucose 200 mL). From the first application, all three patients showed significant improvement of their lesions and amelioration of pain, and they were completely cured in a few days. No adverse effects were recorded. The patients did not show relapses of RAU over a prolonged follow-up. Controlled trials are warranted in order to establish the role of GM-CSF as a valid, alternative option for aphthous ulcerations of the mouth in AIDS patients in whom corticosteroids or thalidomide are not suitable.

The aim of this study was to determine the effectiveness of granulocyte-macrophage colony-stimulating factor (GM-CSF) impregnated gauze in preventing or healing radiation-induced dermatitis. Sixty-one patients were irradiated for vulvar carcinoma. Thirty-seven applied steroid cream at irradiated areas throughout radiotherapy (Group A) and 24 patients applied additionally GM-CSF impregnated gauze (40 micrcog/cm2 of skin-irradiated area, twice per day) in addition to the steroid cream, after 20 Gy of irradiation (Group B). The score of skin reactions (P=0.008, chi2 test) and the time interval of radiotherapy interruption (P=0.037, Mann-Whitney U test) were statistically significantly reduced in Group B patients. Multivariate analysis of variance showed for this group not only a significant reduction in the Sum of Gross Dermatitis Scoring (P<0.001, adjusted for Duration of Dermatitis) but also a significant reduction of the healing time (P=0.02, adjusted for Sum of Gross Dermatitis Scoring). The pain grading was less (P=0.014, chi2 test) and pain reduction was noticed sooner after the application of GM-CSF impregnated gauze (P=0.0017, Mann-Whitney U test). Multivariate logistic regression analysis showed that the only significant effect on dermatitis score is due to Body Mass Index (P=0.034) and the application of GM-CSF (P=0.008). GM-CSF impregnated gauze can be effective in preventing and healing radiation-induced dermatitis and in reducing the interruption intervals of radiotherapy for vulvar carcinomas.

The potential antitumoral effect of granulocyte-macrophage colony-stimulating factor (GM-CSF) led us to evaluate GM-CSF alone or with dacarbazine (DTIC) in metastatic melanoma in first line randomized phase II. Treatment was arm A: GM-CSF: 5 microg kg(-1), bid, 14 consecutive days every 21 days and arm B: GM-CSF: 5 microg kg(-1), bid, day 2 to day 19 every 21 days and DTIC: 800 mg m(-2), day 1 of each cycle. 32 patients (pts) were included, 15 pts in arm A and 17 in arm B. All pts had visceral metastatic sites. 9 had only one metastatic site. The median number of cycles given was 2 in arm A and 3 in arm B. 100% and 89.4% of the planned dose of GM-CSF was given in arm A and arm B respectively. No objective response was obtained. 19 pts experienced at least WHO grade 3 toxicity. All pts had fever, 29 had a decrease in performance status and 23 had pain. Grade 3 toxicity were fever (38.7%), decrease in performance status (32.3%), pain (19.4%) and dyspnoea (12.5%). In this study, GM-CSF alone or in association with DTIC did not induce any antitumoral activity with subsequent toxicity.

We attempted to determine whether various cytokine levels in the serum and synovial fluid (SF) of rheumatoid arthritis (RA) patients are influenced by the performance of filtration leukocytapheresis (LCP). The filtration LCP procedure that used a Cellsorba column (LCP group: n=22; responder subgroup: n=17, non-responder subgroup: n=5) or sham apheresis (control group; n=7) was repeated three times at 1-week intervals. Serum (LCP group, n=22; control group, n=7) and SF (LCP group, n=6; control group, n=3) samples were collected before and after LCP. Levels of tumor necrosis factor alpha (TNFalpha), interleukins (IL-1 beta, IL-2, IL-6, IL-8, IL-10, and IL-15), granulocyte-macrophage colony-stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), RANTES were measured by an enzyme-linked immunosorbent assay. Serum TNF alpha, IL-15, and RANTES were significantly reduced only in the LCP group. Serum IL-10 significantly increased only in the LCP group. In the LCP subgroup, serum IL-15, GM-CSF, and RANTES levels were reduced significantly, while serum IL-10 levels increased significantly only in the responder group after treatment. Serum TNF alpha levels were reduced significantly in both subgroups. Changes in serum IL-10 correlated positively with the improvement of patient's assessment of pain and global severity, and physician's assessment of global severity. These results indicate that the removal of leukocytes from the peripheral blood of RA patients provokes dynamic changes in some cytokine levels in the serum and/or synovial fluid. These changes may explain some of the mechanisms by which the articular symptoms are improved by filtration LCP.

Oral mucositis is a major, often dose-limiting toxicity in modern cancer-therapy, leading to dose reductions or delay in further cancer treatment. It predisposes to life-threatening septic complication during aplasia and substantially reduces quality of life for cancer patients. At present the basic strategies in oral mucositis aim at pain relief and prevention of infectious complications. However, no effective causal prophylaxis or treatment of oral mucositis is widely accepted. The introduction of cytokines, e.g. granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF), the use of cytoprotective agents, e.g. amifostine and the stimulation of basal-cell proliferation by soft-laser irradiation or silver nitrate offer new and hopeful approaches in oral mucositis. Large-scale clinical trials to confirm effectiveness and optimize treatment schedules have to be done.
