Intravenous (IV) administration of purified lipopolysaccharide (LPS) from Salmonella abortus equi to cancer patients induces the formation of high amounts of endogenous cytokines such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). On repeated administration of LPS at 2-week intervals, a marked downregulation of the cytokine response was observed, especially between the first and the second challenge. This study sought to determine whether it would be possible to prevent this downregulation by pretreating patients with interferon-gamma (IFN-gamma), which is known to enhance cytokine production by monocytes and macrophages in vitro. Ten patients with disseminated cancer received a first injection of 4.0 ng LPS/kg. Thereafter, patients were divided into two groups. One group received two further LPS injections (4.0 ng/kg) at 2-week intervals. The second group was pretreated (-12 hours) with 50 micrograms IFN-gamma subcutaneously (SC) before the second and third LPS challenge. To prevent constitutional side effects such as fever and chills, patients received 1,600 mg ibuprofen orally before LPS injection. The results of the current study demonstrate that apart from TNF-alpha and IL-6, two other cytokines, interleukin-8 (IL-8) and granulocyte colony-stimulating factor (G-CSF) are produced in cancer patients in response to LPS. LPS application at 2-week intervals resulted in a transient attenuation of all cytokines (TNF-alpha, IL-6, IL-8, G-CSF) on the second challenge. In the case of TNF-alpha, IL-6, and G-CSF, pretreatment with IFN-gamma not only prevented the downregulation, but enhanced the production of these cytokines to levels higher than those obtained after the first LPS challenge. In contrast, the downregulation of IL-8 remained unaffected by IFN-gamma pretreatment. Further studies are warranted to determine whether the prevention of cytokine downregulation by IFN-gamma following repeated LPS injections is of clinical relevance in respect to the antitumor activity of LPS.

The characteristics and clinical uses of recombinant colony-stimulating factors (CSFs) are described, and the pharmacist's role as a consultant and educator on biotherapeutic substances is discussed. CSFs stimulate the formation and differentiation of the erythrocytes, neutrophils, eosinophils, basophils, monocytes, and platelets that compose the blood cell population. Recombinant CSFs represent a means by which the numbers of hematopoietic cells can be modulated, thus making these agents potentially useful in treating hematologic and immunologic deficiencies. CSFs also can increase the ability of neutrophils and monocyte-macrophages to protect the body against foreign invasion. Granulocyte macrophage colony-stimulating factor (GM-CSF) has increased host defenses in acquired immunodeficiency syndrome patients with Kaposi's sarcoma; increased neutrophil, platelet, and erythrocyte counts in preleukemic patients; and increased neutrophil counts in patients with aplastic anemia. GM-CSF and granulocyte colony-stimulating factor (G-CSF) have appeared to alleviate the drastic decrease in neutrophil counts associated with cytotoxic chemotherapy. G-CSF also has shown promise in stimulating neutrophil production in patients with transitional cell carcinoma, congenital agranulocytosis, and hairy-cell leukemia. Mild adverse effects such as fever, chills, rash, fatigue, myalgia, and bone pain are associated with GM-CSF therapy; G-CSF therapy is associated mostly with mild to moderate bone pain. Areas of education for pharmacists working with biotherapeutic substances include stability, storage temperature, drug interactions, novel drug-delivery systems such as monoclonal antibodies or liposomes, variations in biologic activity, and the evolving nature of the information about these investigational drugs. The pharmacist can anticipate an increasing role as a consultant on the use of CSFs and other biotherapeutic substances.(ABSTRACT TRUNCATED AT 250 WORDS)

We report herein the case of a 40-year-old man with AIDS who was admitted to hospital with severe abdominal pain, fever, and chills. He underwent an emergency laparotomy which revealed a perforated appendix with suppurative peritonitis. An appendectomy with peritoneal drainage was carried out, but the postoperative course was complicated by fever without leukocytosis; however, he gradually improved following treatment with intravenous antibiotics, granulocyte colony-stimulating factor (G-CSF) and immunoglobulins, and made a complete recovery. His postoperative course demonstrates the effectiveness of this treatment regimen for patients with AIDS complicated by infection without an increase in the white blood cell count (WBC).

Myeloid cells can mediate tumor cell cytotoxicity via certain receptors for immunoglobulins. Among the different Fc receptors, the high-affinity IgG receptor (Fc gamma RI, CD64) is a promising trigger molecule because it is selectively expressed on effector cells, including monocytes/macrophages and granulocyte colony-stimulating factor (G-CSF)-primed neutrophils. In vitro, a bispecific antibody (BsAb) (MDX-210, constructed by chemically cross-linking F(ab') fragments of monoclonal antibody (mAb) 520C9 to HER-2/neu and F(ab') fragments of mAb 22 to Fc gamma RI) mediated effective lysis of HER-2/neu overexpressing breast cancer cell lines. HER-2/neu (c-erbB2) is overexpressed in approximately 30% of breast and ovarian carcinomas and is a target for immunotherapy in clinical trials. In vitro assays showed Fc gamma RI-positive neutrophils to constitute a major effector cell population during G-CSF therapy. Based on these preclinical data and a preceding study at Dartmouth (New Hampshire) with a single dose of MDX-210 alone, a combination of G-CSF and MDX-210 is tested in a phase I study in breast cancer patients. In this study, patients receiving G-CSF are treated with escalating single doses of MDX-210. This therapy was generally well tolerated by the treated patients, some of whom reacted with fever and short periods of chills, which were temporally related to elevated plasma levels of IL-6 and TNF-alpha. After MDX-210 application, a transient decrease in the total white blood count and absolute neutrophil count (ANC) was observed. During G-CSF application, isolated neutrophils were highly cytotoxic in the presence of MDX-210 in vitro. These data indicate a potential role for G-CSF and BsAb in immunotherapy.

Methimazole 5 mg three times daily was prescribed in 1994 spring to a woman, aged 53 years, with relapsed hyperthyroidism. The drug was discontinued six weeks after initiation because of leukopenia. Two weeks still later, the patient developed chills, high fever, and a sore throat. The leukocyte count was 1,100/mm3 with 23% granulocytes, 76% lymphocytes and 1% monocytes. The granulocyte count stopped decreasing only three weeks after the drug was discontinued when the recombinant human granulocyte colony-stimulating factor (rhG-CSF) was given; the patient recovered uneventfully. Thus we recommend that the peripheral leukocyte count of patients who receive methimazole therapy must be carefully monitored during the first three months. Furthermore, the use of rhG-CSF for methimazole-induced agranulocytosis abbreviates the period required for marrow recovery after cessation of this offensive drug.

A therapeutic trial of interleukin-3 (IL-3) was carried out in four patients with aplastic anemia refractory to the prior therapies. Daily subcutaneous doses of 2.5, 5.0 or 7.5 micrograms/kg was given for 7 or 14 days. In a patient who had co- and immediate boost-administration of granulocyte colony-stimulating factor (G-CSF) and/or erythropoietin (Epo) and another who had sequential administration of G-CSF and Epo two weeks after IL-3, definite hematological response was obtained during the course after IL-3. In one patient, moderate to severe side effects consisting of facial edema, conjunctival bleeding, chills and fever, were observed after two days' administration of IL-3. Co- or sequential administration of other hemopoietic factor(s) may be essential in IL-3 therapy for aplastic anemia.

A 14-year-old Japanese girl had a lifelong history of skin lesions developing after generalized exposure to cold air; the lesions were often accompanied by systemic symptoms such as fever and chills. The skin lesions were non-pruritic, maculopapular, erythematous eruptions and were neither urticarial nor angioedematous. An ice-cube test was negative. Laboratory examinations showed marked leucocytosis during an acute attack. On the basis of clinical features, histological findings and laboratory data, although these symptoms were sporadic, the most likely diagnosis was familial polymorphous cold eruption, which has also been referred to as familial cold urticaria. Serum levels of granulocyte colony-stimulating factor and interleukin 6 were significantly elevated during an acute attack after cold exposure, suggesting that both cytokines played important parts in the development of her condition.

In this pilot trial of interleukin (IL)-2-treated autologous bone marrow (BM) and peripheral stem cell (PSC)-supported high-dose chemoradiotherapy, we report 36 patients with poor-prognosis leukemia and lymphoma who received BM and/or granulocyte colony-stimulating factor (G-CSF)-mobilized autologous PSCs that had been exposed to IL-2 for 24 hours ex vivo. Patients then received IL-2 by low-dose continuous intravenous (i.v.) infusion until hematologic reconstitution and then by intermediate-dose continuous i.v. infusion for six 2-week maintenance cycles given at 1-month intervals. The median Day to neutrophils over 500/microL was 22 with BM and 10 with PSCs (p = 0.01). The median Day to platelets >20,000/microL was 50 for BM and 25 for PSCs, and to platelets >50,000/microL was 138 for BM and 34 for PSCs (p not significant). After the first three patients received IL-2 at 2 mIU x m(-2) x day(-1) and had slow reconstitution, four patients were treated without IL-2 until the maintenance phase following reconstitution. The remaining 29 patients received the initial "post-infusion" IL-2 at 1 mIU x m(-2) x day(-1). Toxicities associated with the infusion of IL-2-activated cells consisted of chills and fever in about one-half of the patients and transient hypotension in 12%. Low-dose IL-2 by continuous i.v. infusion in the early posttransplant period was associated with exacerbation of fever, diarrhea, and altered mental status in a minority of patients. The major dose-limiting toxicities of maintenance IL-2 were fever, fatigue, gastrointestinal symptoms, skin rash, and dyspnea. Among 24 lymphoma patients, nine are in continuous complete remission (CCR) from 18-48 months, and 15 have died (12 due to relapse and three of therapy-related toxicities). Of 12 acute leukemia patients, two with acute lymphoblastic leukemia (ALL) are in CCR at 38 and 43 months, and one patient who was in cytogenetic but not molecular remission of Philadelphia chromosome-positive ALL died of progressive leukemia at Day 108. Three of nine with myeloid leukemia are in CCR at 21, 46, and 53 months; one is in hematologic and cytogenetic remission of acute promyelocytic leukemia at 55 months with multiple new cytogenetic abnormalities; one is alive at 54 months with pancytopenia after incomplete hematologic recovery followed by multiple new cytogenetic abnormalities (myelodysplasia); and one had an unrelated donor transplant after relapsing 4 months following protocol therapy. One myeloid leukemia patient remains without evidence of relapse, but is transfusion-dependent at 15 months following transplant.

We examined the feasibility of a community blood bank granulocyte transfusion program utilizing community donors stimulated with a single-dose regimen of subcutaneous granulocyte colony-stimulating factor (G-CSF) plus oral dexamethasone. The recipients of these transfusions were neutropenic stem cell transplantation patients with severe bacterial or fungal infection. Nineteen patients received 165 transfusions (mean 8.6 transfusions/patient, range 1-25). Community donors provided 94% of the transfusions; relatives accounted for only 6% of the transfusions. Sixty percent of the community donors initially contacted agreed to participate, and 98% of these individuals indicated willingness to participate again. Transfusion of 81.9 +/- 2.3 x 10(9) neutrophils (mean +/- SD) resulted in a mean 1-hour posttransfusion neutrophil increment of 2. 6 +/- 2.6 x 10(3)/microL and restored the peripheral neutrophil count to the normal range in 17 of the 19 patients. The buccal neutrophil response, a measure of the capacity of neutrophils to migrate to tissue sites in vivo, was restored to normal in most patients following the transfusion. Chills, fever, and arterial oxygen desaturation of >/= 3% occurred in 7% of the transfusions, but these changes were not sufficient to limit therapy. Infection resolved in 8 of 11 patients with invasive bacterial infections or candidemia. These studies indicate that transfusion of neutrophils from donors stimulated with G-CSF plus dexamethasone can restore a severely neutropenic patient's blood neutrophil supply and neutrophil inflammation response. Further studies are needed to evaluate the clinical efficacy of this therapy.

A 70-year-old Japanese woman with renal dysfunction under hemodialysis presented with vomiting and chill with fever. Over the previous 24 weeks she had been taking 75 mg of ranitidine after hemodialysis. Other medications taken were prednisolone, furosemide, alpha-calcidol, amlodipine and calcium carbonate. Before starting ranitidine, she had been treated with famotidine for about 2 years without complication. Hematological inspection on admission revealed agranulocytosis with WBC of 400/mm3. Ranitidine was discontinued and granulocyte colony-stimulating factor (G-CSF) was started. On Day 3, laboratory data showed slight improvement of cytopenia with WBC of 1,000/mm3. On Day 6, her hemogram showed marked improvement with WBC of 11,700/mm3 and G-CSF was discontinued. She was discharged on Day 10. Several cases describing ranitidine-induced cytopenia are associated with the use of ranitidine at a dose of 150 mg/day or higher, and adverse reactions were found within 2-35 days after beginning ranitidine treatment. In the case described here, however, the adverse reaction occurred after a longer treatment period with ranitidine at a lower dose. In conclusion, ranitidine should be administered with great caution to patients with severe renal dysfunction.
