We studied the remission rate and adverse effects in THP-COPBLM therapy consisting of pirarubicin (THP), which is said to be less cardiotoxic than doxorubicin. Subjects were 21 non-Hodgkin's lymphoma (NHL) patients older than 70 years of age. Of 21 patients, complete remission (CR) was achieved in 16 patients (76.2%) and partial remission in 2 patients (9.5%). Classified by stages, CR was achieved in 5 out of 6 patients in stage II, 7 out of 8 in stage III and 4 out of 7 in stage IV. Two-year survival rate was 61.5%. Adverse effects were observed in 7 patients (33.3%) with grade 3 or above leukocytopenia, 2 (9.5%) with thrombocytopenia and 1 (4.8%) with gastrointestinal symptoms. However, no abnormality in EKG was found, and the left ventricular ejection fraction in echocardiography did not differ before and after therapy. One patient each developed
pneumonia
and sepsis when they had granulocytopenia. THP-COPBLM therapy seemed useful in treatment of elderly patients with NHL. There were few adverse effects such as gastrointestinal symptoms or cardiotoxicity. However, leukocytopenia was observed in many patients despite combined use of
G-CSF
, suggesting the dose and administration method of THP should be studied further.

Colony-Stimulating Factors (CSFs) are a family of glycoproteins that are required for the proliferation and differentiation of hematopoietic progenitor cells. Among these factors,
G-CSF
and GM-CSF are principally involved in the production of neutrophils. They have been demonstrated to be effective in correcting neutropenia during cytotoxic chemotherapy or bone marrow transplantations. Beside their hematopoietic action, recent data indicate that
G-CSF
and GM-CSF also have stimulatory effects on mature neutrophils function. The functional properties of neutrophils that are enhanced by
G-CSF
and GM-CSF are those related primarily to the host's defense against microorganisms. For Gm-CSF those stimulatory effects also concern the macrophages. Investigations of several animal models of severe bacterial infection and specially
pneumonia
have indicated that exogenous recombinant
G-CSF
or GM-CSF can significantly enhance host defenses and improve rates of survival. Trials of recombinant
G-CSF
in combination with antibiotics for the treatment of severe
pneumonia
in noneutropenic patients have recently been initiated. First results confirm the good tolerance of recombinant
G-CSF
. Further prospective studies are required to determine the effectiveness and the conditions of administration of
G-CSF
and GM-CSF in this indication.

In a multi-centre phase I study we investigated the possibility of reducing the interval between courses of standard CHOP (cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, vincristine 2 mgs day 1, and prednisolone 40 mg/m2 days 1-8) from 21 days to 15 days and then 10 days using granulocyte colony stimulating factor (r-MetHuG-CSF (Amgen)-filgrastim) to accelerate neutrophil recovery. Patients received CHOP followed by
G-CSF
5 micrograms/kg s.c. from day 2 to the day before the next course (e.g. days 2-14 for the 15-day interval). A total of 28 patients with newly diagnosed intermediate grade or high grade NHL were studied. Four patients were studied at a 21-day interval, six patients were treated at a 15-day interval and subsequently six patients at a 10-day interval. Following analysis of this initial cohort, a further 12 patients were evaluated; four at the 15-day interval, and eight at the 10-day interval. No dose-limiting toxicity was seen in the four patients receiving 21-day CHOP. Dose-limiting toxicity was seen in 4/10 patients treated at the 15-day interval (M:F 7:3, median age 55.5, range 39-67 years). This consisted of infection in two patients, recurrent infection and debility in a third, and mucositis in a fourth. Seven patients experienced one or more infectious episodes requiring antibiotics (median number of episodes: 2, range 1-4). Fourteen patients (M:F 4:3, median age 47.5, range 25-63 years) were treated at the 10-day interval. Dose-limiting toxicity was seen in six patients. This consisted of severe mucositis in three patients, neutropenia and thrombocytopenia on two separate occasions in one patient, and steroid-induced gastritis in two patients. Nine patients had one or more documented infections (median: 2, range 1-3) requiring antibiotics, of which six were severe (WHO grade 3 or 4). One patient died of Pneumocystis carinii (PCP)
pneumonia
. In summary,
G-CSF
(filgrastim) will facilitate the shortening of the dosage interval between cycles of CHOP chemotherapy due to accelerated hematological recovery. However, non-hematological toxicity due to the shorter dosage interval is increased and infective episodes are frequent.

We describe 3 patients with acute myeloblastic leukemia (AML), who received rhG-CSF for infections such as
pneumonia
or for prophylaxis of infection, and who achieved complete remission. They had not received any antileukemic therapy before or during the administration of rhG-CSF. These findings suggest the possibility that complete remission can be brought about by
G-CSF
itself in some patients with AML.

The objectives of the present study were to: (1) evaluate the safety of Filgrastim therapy in non-neutropenic patients with severe community-acquired
pneumonia
; (2) determine the absolute neutrophil count (ANC) response to various dosages of Filgrastim in non-neutropenic patients with active infection; and (3) describe the impact of therapy with Filgrastim in combination with antibiotics on selected
pneumonia
-related clinical parameters. The study design was an open-label, dose-ranging, clinical trial, set in the General Clinical Research Unit of a large, public community hospital. The study population consisted of 30 patients who had presented to the Emergency Department with severe, community-acquired
pneumonia
. One of five dosages (75, 150, 300, 450 or 600 micrograms day-1) of Filgrastim (r-metHuG-CSF) was given subcutaneously daily for 10 days, until discharge or until the absolute neutrophil count > 75 x 10(9) l(-1), whichever was earlier. Vital signs, pulse oximetry, arterial blood gases, daily complete blood counts with differential, serum chemistries, coagulation profiles, electrocardiograms, chest radiographs, plasma
G-CSF
concentrations and duration of hospitalization were measured. There was no evidence of Filgrastim-related lung injury or evidence of extra-pulmonary toxicity. There was no apparent dose-response effect of Filgrastim on
pneumonia
-related clinical variables. Dosages of Filgrastim between 150 and 600 micrograms day-1 had similar effects on increasing the ANC. Filgrastim appeared to be safe in non-neutropenic patients with severe, community-acquired
pneumonia
when given in dosages of 75-600 micrograms day-1 in combination with appropriate antibiotic therapy. Further study is needed to determine the effect of Filgrastim on morbidity, mortality and duration of symptoms in this patient population.

A 44-year-old Japanese man who had suffered from bronchial asthma since childhood was given the diagnosis of chronic eosinophilic
pneumonia
because of his symptoms, chest roentgenographic findings, and the results of a transbronchial lung biopsy. At the time of the onset of the disease, the pleural effusion contained 73% eosinophils. Symptoms were relieved and the laboratory findings returned forward normal after a short course of high-dose corticosteroids. The concentrations of IL-5, IL-6, and
G-CSF
in pleural fluid and in serum were very high; the concentrations of these cytokines were 3 times to 35 times higher in pleural fluid than in serum. In contrast, no IL-3 or GM-CSF was detected in any of these samples. The precise etiology of chronic eosinophilic
pneumonia
is still unclear, but this case suggests that inappropriate production of IL-5, IL-6 and
G-CSF
in the lung play a pivotal role in this disease. Inhibition of the production of these cytokines may be another therapeutic approach to this disease.

A phase II trial was conducted in order to assess the efficacy and toxicity of paclitaxel given at a dose of 175 mg/m2 in a 3-hour infusion every 3 weeks in patients with recurrent or cisplatin (CDDP) carboplatin-refractory ovarian cancer. Forty-two patients with a median age of 61 years (range 34-76 years) entered the study. Most patients had bulky disease. Thirty-three patients (78.5 %) presented with stage III and IV diseases. Twenty-two patients (52.3%) had previously been treated with only 1 regimen and 20 patients (47.7%) with > or = 2 regimens. The median treatment interval from the last previous therapy was 4.5 months (range 2-26 months). From 41 patients evaluable for response, 3 (7.3%) achieved a complete and 4 (9.8%) a partial response. All 3 complete and 2 out of the 4 partial responders had previously received > or = 2 chemotherapeutic regimens. Grade 3-4 toxicities included granulocytopenia (35%), which was of short duration, neurotoxicity (9.75%) and alopecia (60.9%). Two patients with grade 4 neutropenia were hospitalized due to
pneumonia
, which was successfully treated by broad-spectrum antibiotics and administration of
G-CSF
. A severe hypersensitivity reaction occurred in 1 patient early during the first cycle, resulting in discontinuation of treatment. Median relapse-free survival was 6.9 months, median time to progression 6.2 months and median survival 13.2 months. In conclusion, paclitaxel given at a dose of 175 mg/m2 as a 3-hour infusion every 3 weeks appears to be an efficacious and well-tolerated treatment in patients with recurrent or CDDP/carboplatin-refractory ovarian cancer.

An 8.5-month-old boy with Wiskott-Aldrich syndrome received a sibling matched bone marrow transplant from his healthy non-identical twin brother. The donor had primary human herpes virus 6 (HHV-6) infection around the time of bone marrow donation. The recipient had hepatitis in the first week and then developed fever and rash on day 18. Skin biopsy was shown to have HHV-6 antigen and his peripheral blood leukocytes were HHV-6 DNA positive. He engrafted on day 18 but the ANC dropped from 5.5 x 10(9)/l (day 23) to 0.48 x 10(9)/l (day 34) with persistent HHV-6 DNAemia. Bone marrow on day 35 was positive for HHV-6 DNA. He was treated with
G-CSF
and ganciclovir with good response. He later had
pneumonitis
which was treated empirically with foscarnet, ceftazidime and clarithromycin.

Considerable experimental evidence in animals suggests that treatment with
G-CSF
may have a beneficial effect in the management of severe infections in non-neutropenic hosts. This beneficial effect is attributed to an enhancement of granulopoiesis and neutrophil function, the latter possibly involving up-regulation of receptors on neutrophils that are involved in antibody-mediated cytotoxicity and killing of microorganisms. We compared neutrophil function and phenotype in blood and bronchoalveolar lavage fluid (BALF) of 10 patients with severe ventilator-dependent
pneumonia
, at baseline and following initiation of
G-CSF
treatment as adjunct to standard therapy.
G-CSF
treatment was associated with three-fold increased blood neutrophil counts at day 3 of treatment compared with baseline counts. Mean serum
G-CSF
concentration increased from 313 to 2007 pg/ml. After correction for lavage dilution effects, BALF
G-CSF
levels did not differ significantly from baseline, nor did neutrophil receptor expression (FcgammaRI, FcgammaRII, FcgammaRIII, CR3, and L-selectin) or indicators of neutrophil function such as respiratory burst activity, phagocytosis and killing of Candida albicans in BALF or blood. The mortality in this group of patients was 30% and compared favourably to the APACHE II-derived predicted mortality of 60%. We conclude that the possible therapeutic benefit of
G-CSF
administration in the early phase of severe bacterial pneumonia is not readily explained by its effect on baseline indicators of neutrophil function or receptor expression.

A 60-year-old woman was admitted in June 1993, because of anemia and purpura and given a diagnosis of acute myelogenous leukemia with trilineage dysplasia. She entered partial remission (PR) after three courses of low-dose Ara-C and
G-CSF
, but never reached complete remission (CR) in spite of additional chemotherapy. In October 1994, the number of leukocytes, myeloblasts, and erythroblasts in the patient's peripheral blood increased, and her clinical condition deteriorated. The disease was resistant to other therapy. The patient had
pneumonia
and died of septic shock in December 1994. A chromosomal analysis performed on admission showed 46,XX,t(3;5) (q21;q31) [9/9]. As an additional chromosomal abnormality, deletion of the X chromosome was observed in January, 1994. Analysis of the p53 gene by the polymerase chain reaction-single strand conformation polymorphism method showed one base transposition, from TAT to TGT (Tyr to Cys), at codon 220 of exon 6. Karyotype evolution and p53 gene mutation were observed during the disease course and may have been related to progression of the disease.
