Several clinical trials have demonstrated that granulocyte colony-stimulating factor (G-CSF) accelerates the recovery of neutropenia in chemotherapy-induced bone marrow suppression. In this report, we describe a 46-year-old female with glioblastoma multiforme who developed interstitial pneumonia due to administration of G-CSF during the phase of immunochemoradiotherapy-induced neutropenia. Thirty-three days after starting immunochemoradiotherapy (ACNU, VCR, IFN -beta, radiation), she developed neutropenia (1,000/microliters). Administration of G-CSF at doses of 125-250 micrograms/day led to an increase of peripheral neutrophil counts. Eleven days later, the patient developed sudden severe respiratory failure and cyanosis with worsening of lung shadows. Blood gas levels on room air were PaO2 49.3mmHg, PaCO2 28.0mmHg, and pH 7.46. At this time, her neutrophil count had risen to 26,080/microliters. LDH and alpha - HBD had also increased to 1,439 IU/l and 1,117IU/l respectively. Chest radiograph and CT scan demonstrated interstitial pneumonia. After treatment with methyl prednisolone, her respiratory symptoms were gradually resolved. A number of side-effects have been reported with granulocyte-macrophage colony-stimulating factor (GM-CSF). These include fluid retention with pericardial and pleural effusion, fever, bone pain, fatigue, and rash. This report also suggests that G-CSF might be a cause of interstitial pneumonia during the phase of immunochemoradiotherapy-induced neutropenia.

In high-grade malignant non-Hodgkin's lymphomas (hNHL) recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) was evaluated as support to chemotherapy. In a phase III trial, 172 patients (age 18-73 years, stage II-IV) were risk-stratified according to LDH levels and lymphoma size and randomized to receive rhGM-CSF (400 micrograms) (87 patients) or placebo (85 patients) subcutaneously days 8-14 of each cycle of an intensified COP-BLAM regimen. RhGM-CSF significantly reduced the length and nadir of neutropenia, the length of fever episodes, the frequency of all and of severe infections, and of hospitalization and antibiotic requirements. Complete response rates were 63% for all patients and 64% vs. 61% (n.s.) in the rhGM-CSF vs. the control group. Deviations from protocol in applied dosages of myelotoxic drugs and in cycle intervals maintained differed slightly in favor of the rhGM-CSF arm. However, there were no significant differences in overall survival between the GM-CSF treatment and control groups (21 vs. 23 months). Early relapse rates were markedly lower than in the standard-dose COP-BLAM/IMVP-16 regimen. Thus, GM-CSF abates toxic side effects of chemotherapy and may help to maintain dose intensity in high-risk hNHL.

In order to reduce anaemia in patients with myelodysplastic syndromes (MDS) a stepwise treatment protocol including erythropoietin (EP) and granulocyte-macrophage colony-stimulating factor (GM-CSF) was designed. Thirty-seven MDS patients (stages I-III) with symptomatic anaemia were first given EPO 10,000 U s.c. 3 times weekly for 6 weeks. Those not responding, i.e. increased their haemoglobin levels > 15 g/l, proceeded into the second phase of the study where GM-CSF (200 micrograms/d. s.c. on weeks 1-6) was combined with EPO (10,000 U s.c. 3 times weekly on weeks 5-14). Following the initial EPO treatment phase, 14 of the 37 patients (38%) responded with increased haemoglobin levels. Responders were significantly different from non-responders in that their pre-treatment values of s-EPO, s-LDH and bone marrow blast cell counts were lower, their baseline haemoglobin levels higher and their transfusion dependency less pronounced. Eighteen of the 23 non-responders proceeded into the second phase, 13 of those were evaluable having completed the entire schedule. Three of the 13 initially EPO resistant patients (23%) responded to the GM-CSF/EPO combination with increased haemoglobin levels, suggesting a positive synergy between the two cytokines. Thus, the overall response rate to the present protocol was 46% (17 of 37 cases), but only a limited subset of the patients did clearly benefit from the combined GM-CSF/EPO administration. Therefore, we believe this step-wise approach to multiple growth factor treatment in MDS, starting with EPO alone and reserving the combination for refractory cases, has considerable advantages, taking into account both medical and socio-economical aspects.

Idiopathic pulmonary alveolar proteinosis (IPAP) is a rare disease characterized by excessive amounts of lipoproteinaceous material in the alveolus. This report presents an interim analysis of nationwide epidemiological data from Japanese patients with pulmonary alveolar proteinosis, and the roles of serum markers for IPAP. (i) The nationwide demographic data from 166 Japanese patients with IPAP are shown. The female to male ratio was 1:2, and the average age was 51 +/- 14 years old (age range: 15-79 years) at registration or diagnosis. A total of 30% of patients with IPAP have a poor clinical course. In total, 30% of patients were treated with whole lung lavage therapy (WLL). Under WLL, the patients significantly improved in the short term, but 40% of the patients who underwent WLL worsened again. A new strategy such as granulocyte-macrophage colony-stimulating factor (GM-CSF) therapy for intractable PAP is required. (ii) The correlation of serum KL-6, carcinoembryonic antigen, surfactant proteins D and A, and LDH with disease severity suggests their potential as disease markers. In contrast, serum anti-GM-CSF antibody did not correlate with disease severity, but is a specific marker for the diagnosis of IPAP. The combined measurements of the serum markers may well prove very useful for both the diagnosis and the management of IPAP patients.
