In a phase I study, the sequentially administered combination of recombinant human interleukin-3 (rhIL-3) and rhGM-
CSF
was compared with treatment with rhIL-3 alone in 15 patients with advanced tumors but normal hematopoiesis. Patients were initially treated with rhIL-3 for 15 days. After a treatment-free interval, the patients received a second 5-day cycle of rhIL-3 at an identical dosage, immediately followed by a 10-day course of rhGM-
CSF
, to assess the toxicity and biologic effects of this sequential rhIL-3/rhGM-
CSF
combination. rhIL-3 doses tested were 125, and 250 micrograms/m2, whereas rhGM-
CSF
was administered at a daily dosage of 250 micrograms/m2. Both cytokines were administered by subcutaneous (SC) bolus injection. rhIL-3/rhGM-
CSF
treatment was more effective than rhIL-3 but equally effective to each other in increasing peripheral leukocyte counts, especially neutrophilic and eosinophilic granulocyte counts. In contrast, both modes of cytokine therapy raised the platelet counts to the same degree. rhIL-3/
GM-CSF
treatment was more effective than rhIL-3 in increasing the number of circulating hematopoietic progenitor cells BFU-E and CFU-GM. High-dose rhIL-3, but not low-dose rhIL-3, was as effective as the rhIL-3/rhGM-
CSF
combinations in increasing the number of circulating CFU-GEMM. The increase in absolute neutrophil counts correlated with the increase in the number of circulating CFU-GM. Side effects, mainly fever, headache,
flushing
, and sweating, were generally mild, but in two patients the occurrence of chills, rigor, and dyspnea after initiation of
GM-CSF
treatment necessitated dose reduction and discontinuation, respectively. These results indicate that sequential treatment with rhIL-3 and rhGM-
CSF
is as effective as single-factor treatment with rhIL-3 in stimulating platelet counts, whereas the effect of combination therapy on neutrophil counts and circulating progenitor cells is superior.

Leukopenia or pancytopenia as a result of bone marrow dysfunction are manifestations of various diseases or complications of therapeutic regimens. The spectrum of diseases associated with leukopenia is wide and includes congenital as well as acquired neutropenias secondary to conditions such as myelodysplastic syndromes, AIDS, malignant tumors with or without chemotherapy-enhanced neutropenia, bone marrow transplantation or therapeutic or accidental radiation. The morbidity and mortality of infectious diseases is greatly enhanced during neutropenic phases. Over the last few years attempts have been made to shorten the duration and lessen the severity of neutropenia in patients with the above conditions by administration of Granulocyte Macrophage Colony Stimulating Factor (G-CSF). Both cytokines were successfully tested in phase I and II trials. Treatment with
GM-CSF
or G-
CSF
results in a dose-dependent increase of the neutrophil count.
GM-CSF
also increases the number of eosinophils and monocytes in peripheral blood. The effect of both cytokines on the neutrophil count is transient as long as the underlying disease persists. This prompted the institution of maintenance therapy, which has been successfully used with either cytokine. Long-term treatment is usually well tolerated and results in a reduction in the frequency of infections as well as in the duration of antibiotic treatments. Side effects of
GM-CSF
or G-
CSF
are usually mild and include fever, myalgia, bone pain, and erythema. A number of patients developed dyspnea, hypotension, sweating,
flushing
and erythema after the first dose of
GM-CSF
in each treatment cycle. This first-dose reaction occurs more frequently after intravenous than reactions were reported with G-
CSF
. Some patients with myelodysplastic syndrome progressed to acute myeloic leukemia during or after treatment with
GM-CSF
or G-
CSF
. Most of these patients presented with an increased fraction of blasts in the bone marrow, which preceded the treatment with the colony stimulating factors. Since
GM-CSF
and possibly G-
CSF
may increase the risk of developing acute leukemia in patients with myelodysplastic syndrome, it appears prudent to limit the use of these cytokines in patients with this disease. The subcutaneous route of administration appears to be preferable to intravenous administration, since the incidence and severity of side effects are reduced. While many questions concerning dosage, long-term therapy and combination therapy still remain unanswered, the information presented in this review concerning the clinical use of these cytokines warrants an optimistic outlook.

The in vivo effect of yeast-derived recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) was investigated in 29 patients with advanced malignancy in phase Ib trial. Patients were treated at six different dose levels (30-1000 micrograms/m2/day) with either daily intravenous bolus injection or 24 hours continuous infusion for 5 days or 2 weeks. Administration of rh
GM-CSF
resulted in a broad spectrum of dose-, route-, and schedule-dependent hematopoietic effects. Sustained infusion of rh
GM-CSF
elicited a maximum 17-fold average peak increase of the total white blood cell (WBC) count with mainly neutrophils, eosinophils, and monocytes accounting for this rise, and increases in bone marrow cellularity with a shift to immature myeloid elements. Elevation of lymphocytes, platelets and reticulocytes was not induced. Within one week after discontinuation of treatment the leukocytosis had disappeared. Adverse reactions encountered with rh
GM-CSF
seen in 65% of the patients studied were never life-threatening and always reversible. They included mild myalgias, facial
flushing
, low-grade fever, headache, bone discomfort, nausea, dyspnoea and transient decline of platelet counts. These results suggest that rh
GM-CSF
can be safely administered at the doses and schedules employed and that it can induce in vivo some of the biological effects reported in in vitro studies. Although no objective antitumour responses have been seen, the ability of rh
GM-CSF
to increase turnover and function of leukocytes in vivo may prevent neutropenia and infections, when
GM-CSF
is adjunctively added to cytotoxic cancer therapy.

The in vivo effect of yeast-derived recombinant human granulocyte-macrophage colony-stimulating factor (rh
GM-CSF
) was investigated in 30 patients with advanced malignancy in a phase Ib trial. Patients were treated at four different dose levels (120 to 1,000 micrograms/m2/d) by either daily intravenous (IV) bolus injection or 24-hour continuous infusion. Administration of rh
GM-CSF
resulted in a broad spectrum of dose- and schedule-dependent hematopoietic effects. Sustained infusion of rh
GM-CSF
elicited a maximum 17-fold average peak increase of the total WBC count with mainly neutrophils, eosinophils, and monocytes accounting for this rise, and increases in bone marrow cellularity with a shift to immature myeloid elements. Elevation of lymphocytes, platelets, and reticulocytes was not induced. Within five days after discontinuation of treatment the leukocytosis had disappeared. Adverse reactions encountered with rh
GM-CSF
seen in 65% of the patients studied were never life-threatening and always rapidly reversible. They included mild myalgias, facial
flushing
, low-grade fever, headache, bone discomfort, nausea, dyspnea, and transient decline of platelet counts. These results suggest that rh
GM-CSF
can be safely administered at the doses and schedules used and that it can induce in vivo some of the biological effects reported in in vitro studies. Although no objective antitumour responses have been seen, the ability of rh
GM-CSF
to increase number and function of leukocytes in vivo may prevent neutropenia and infections when
GM-CSF
is added to cytotoxic cancer therapy.

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)

The effect of rhIL-3 was investigated in 32 patients with newly diagnosed non-Hodgkin lymphoma in a phase I/II trial. All patients received 6 cycles of standard CHOP chemotherapy, and each patient was his own control where rhIL-3 was given as a daily s.c. injection for 14 days (day 2-15) in cycle 2 and 4, while cycle 1 and 3 were control cycles. Five dose levels were examined (0.5 - 1 - 5 - 7.5 - 10 micrograms/kg). Compared to the other more lineage-specific hemopoietic growth factors G- and
GM-CSF
, the effect of rhIL-3 on the hemopoiesis was less dramatic and more delayed, i.e. the most apparent effect was observed in the 2 weeks of treatment. Thus, the neutrophil counts from days 15 to 22 following CHOP were significantly raised and the duration of neutropenia was shorter (significantly only at 10 micrograms/kg), while the nadir values were unaffected. Platelet recovery from days 12-22 was significantly increased and nadir values occurred earlier compared to control cycles, but were only increased in some subsets. Other cell populations affected moderately in the recovery period were eosinophils and monocytes. Reticulocytes increased, but no effect on hemoglobin or RBC transfusion requirement was noted. Only moderate adverse reactions occurred such as fever, chills,
flushing
of the face and flu-like symptoms. There was no evidence of stimulation of tumor growth. Most significant, the rhIL-3 treatment at all but the lowest dose levels led to an improved tolerance to chemotherapy, as indicated by a decline in number of delayed cycles. A conclusion concerning the role of rhIL-3 as post-chemotherapy adjuvant should await studies using rhIL-3 in combination with more lineage-restricted hemopoietic growth factors.

We report the case of a 41-year-old man infected with human immunodeficiency virus who had two episodes of aseptic meningitis that occurred 2 weeks apart; the first was associated with ingestion of trimethoprim-sulfamethoxazole (TMP-SMZ) and the second was associated with ingestion of TMP alone. Onset of fever, headache, and
flushing
was abrupt, followed by somnolence, hearing loss, and aphasia. Analysis of the
CSF
showed pleocytosis and an elevated protein level. The findings resolved within 48 hours after withdrawal of the drug. We also review 18 previously reported cases of TMP-SMZ- or TMP-induced meningitis, 17 of which occurred in women. In all of these cases, a similar abrupt onset and resolution were noted. Six of the 18 patients had collagen-vascular diseases. All but two of these patients had multiple recurrent episodes of meningitis before the diagnosis was made. We conclude that the diagnosis of TMP-SMZ- or TMP-induced meningitis should be considered when a patient receiving these drugs has recurrent episodes of aseptic meningitis.

Samples of rib bone were collected and preserved under various conditions. The effect of preserving a piece of bone on the yield of hematopoietic stem cells was analyzed. Bone marrow cells were collected by means of
flushing
the bone marrow cavity with medium. The initial number of nucleated bone marrow cells collected from the donor's excised rib ranged from 0.8 x 10(8) to 2.3 x 10(8) per 1 cm of rib with an average of 1.21 x 10(8) (n = 7). In addition, the initial number of mononuclear bone marrow cells ranged from 1.1 x 10(7) to 4.8 x 10(7) per 1 cm of rib with an average of 2.47 x 10(7) (n = 7). The percentage loss of mononuclear bone marrow cells from rib preserved in medium for 48 hours at 4 degrees C, was less than 30%. A colony-forming assay by the methylcellulose method, complemented with r-G-CSF, r-
GM-CSF
, r-IL3, r-IL6, and r-erythropoietin, was done serially using bone marrow buffy-coat cells. These cells were obtained from the pieces of rib that were stored under various conditions. The number of CFU-GM and BFU-E that proliferated in this culture was 41.1 +/- 5.5 and 15.2 +/- 2.7 per dish. If the bone was preserved at 4 degrees C for 48 hours following excision, the recovery of CFU-GM and BFU-E from the bone marrow cells was greater than 50%. The effect of cryopreserving bone marrow mononuclear cells on the yield of hematopoietic cells was also analyzed. The percentage loss of proliferated hematopoietic cells by cryopreservation was less than 30% for bone marrow cells. Bone marrow cells were collected from pieces of rib obtained from cadaveric donors by means of the same method. The average number of nucleated bone marrow cells and MNCs was 1.26 x 10(7) and 2.30 x 10(7) per 1 cm of rib, respectively. The average number of CFU-GM and BFU-E that was detected by the colony-forming assay was 33.4 +/- 5.35 and 11.7 +/- 1.75 per dish, respectively. The percentage loss of proliferated hematopoietic cells by cryopreservation was less than 40% for bone marrow cells from cadaveric donors. These data, which reveal that hematopoietic bone marrow stem cells could be collected from a piece of pipe bone that was without circulation, suggest that it is possible to use pipe bone from cadaveric donors as a source of hematopoietic stem cells for bone marrow transplants.(ABSTRACT TRUNCATED AT 400 WORDS)

Registered nurses (RNs) and clinical pharmacists in the Hematology-Oncology Clinic at Walter Reed Army Medical Center conducted a descriptive study to determine the effectiveness and safety of using indwelling peripheral intravenous catheters (pics) for daily administration of various chemotherapeutic agents given intermittently over a 3-5 day period to outpatients. Eighty-nine adult outpatients requiring daily doses of chemotherapy including Fluorouracil (5-FU) (Solopak, Elk Grove Village, IL), Leucovorin (
Immunex
, Seattle, WA), Cisplatin (CDDP) (Bristol-Meyers, Princeton, NJ), Etoposide (VP-16), (Gensia, Irving, CA), Topotecan (SmithKline Beecham, Philadelphia, PA), or Taxol (Mead Johnson, Princeton, NJ), plus antiemetics were studied. Vialon 20-, 22-, or 24-gauge indwelling PICs (Becton Dickinson, Sandy, UT), were placed. Approximately 80% of patients successfully completed treatment with the original PIC in place. Daily
flushing
of the PIC with 2 ml [corrected] of Heplock U100 (Elkins-Sinn, Cherry Hill, NJ), maintained Heplock patency.

Recombinant human Interleukin-3 (RhIL-3) is a haemopoietic growth factor with effect both on early and differentiated cells, such as eosinophils and basophils, and it also acts as a histamine-releasing agent. The purpose of the present study was to examine whether in vivo rhIL-3 administration after chemotherapy affected basophil histamine levels and whether a concordance between rhIL-3 induced histamine release and side effects during the treatment could be demonstrated. Thirty patients with non-Hodgkin's lymphoma entered the study. All patients received 6 courses of chemotherapy, rhIL-3 was administered subcutaneously once daily after the second and the fourth course of chemotherapy from cycle day 2-15 at the dose levels 0.5, 1.0, 5.0, 7.5 and 10 micrograms/kg with 6 patients at each dose level. In cycle 6 recombinant human Granulocyte-Macrophage Colony-Stimulating Factor (rhGM-CSF) (3.0 micrograms/kg) was administered sequential/concurrent day 9-15 to rhIL-3 (day 2-15) at all dose levels except 7.5 micrograms/kg, where rhIL-3 was given day 2-8 and rhGM-
CSF
sequential day 9-15. Cycles 1, 3 and 5 served as control cycles with no cytokine therapy. During rhIL-3 treatment, and after CHOP chemotherapy, the basophil counts increased moderately especially during the recovery period day 15-22, and mainly at the two highest dose levels 7.5 and 10 micrograms/kg, but never exceeded the normal upper limit. Histamine levels in basophils were the same in patients before chemotherapy and healthy volunteers, and except from a trend to increased histamine level at 10 micrograms/kg on day 15, no difference was noted between rhIL-3 cycles and control cycles. Within 3-4 hr after rhIL-3 administration, a drop in histamine level in basophils was noted, which could be due to histamine-releasing properties of rhIL-3 as previously demonstrated by in vitro studies. No serious side effects were noted during the cytokine treatment, and despite that most patients had mild
flushing
of the face, neck and upper chest, no patients experienced sensitization throughout the study. Although a significant increase in rhIL-3-induced histamine release from basophils was noted in some of the patients, no correlation to the dose of rhL-3 was found, and no correlation was noted between side effects and histamine release or histamine levels in basophils.
