Fever and chills occur frequently with amphotericin B (AB) administration, but the mechanism that causes these reactions has not been definitively established. A variety of proinflammatory cytokines, including interleukin-1 (IL-1) and tumor necrosis factor, have been shown to be important mediators of fever. In order to clarify the cellular and biochemical responses associated with AB-induced fever, the experiments described sought to (i) establish whether human mononuclear cells exposed to AB in vitro expressed IL-1 beta, (ii) evaluate whether clinically used premedications for fever prophylaxis in AB-treated patients were effective in down-regulating IL-1 beta expression in vitro, (iii) evaluate whether methylxanthine agents with immunomodulatory actions effected in vitro IL-1 beta expression, and (iv) define the dose and time dependency of the modulating effects. Peripheral blood mononuclear cells were isolated by density centrifugation and resuspended to 10(6) cells per ml in culture wells of Linbro plates. When cocultured for 2 h with human mononuclear cells, both Escherichia coli lipopolysaccharide and AB stimulated IL-1 beta expression in a dose-related fashion. AB-induced IL-1 beta expression was suppressed by hydrocortisone (HC), pentoxifylline, and an investigational theobromine, A81-3138, in a linear, dose-related manner. In contrast, indomethacin, meperidine, and diphenhydramine had no effect on IL-1 beta expression. Our in vitro data indicate that serum HC concentrations of greater than 1 to 2 micrograms/ml may be sufficient to modulate IL-1 beta expression. Pentoxifylline and A81-3138 may also be effective in modulating IL-1 beta expression by mononuclear cells at concentrations achievable in serum. These new agents may prove to be effective alternatives to HC or may be added with HC to suppress febrile reactions secondary to AB administration. Clinical studies with pentoxifylline as a premedication for AB seem warranted.

Twenty-eight evaluable patients with metastatic cancer refractory to standard therapy received escalating doses of muramyl tripeptide phosphatidylethanolamine (MTP-PE) (.05 to 12 mg/m2) in phosphatidylserine (PC):phosphatidylcholine (PS) liposomes (lipid:MTP-PE) ratio 250:1). Liposomal MTP-PE (L-MTP-PE) was infused over 1 hour twice weekly; doses were escalated within individual patients every 3 weeks as tolerated for a total treatment duration of 9 weeks. Routine clinical laboratory parameters, acute phase reactants and various immunologic tests were monitored at various time points during treatment. Toxicity was moderate (less than or equal to grade II) in 24 patients with chief side effects being chills (80% of patients), fever (70%), malaise (60%), and nausea (55%). In four patients L-MTP-PE treatment was deescalated due to severe malaise and recurrent fever higher than 38.8 degrees C. The maximum-tolerated dose (MTD) was 6 mg/m2. Significant (P less than .05) increases in WBC count, absolute granulocyte count, ceruloplasmin, beta 2-microglobulin, c-reactive protein, monocyte tumoricidal activity, and serum IL-1 beta were found. Significant decreases in serum cholesterol were also observed. Clearance of intravenously (iv)-infused technetium-99 (99mTc)-labeled liposomes containing MTP-PE in four patients was biphasic; gamma camera scans revealed uptake of radiolabel in liver, spleen, lung, nasopharynx, thyroid gland, and tumor (two patients). No objective tumor regression was seen. In view of its definite immunobiologic activity and lack of major toxicity, additional phase II and adjuvant trials of L-MTP-PE are warranted.

Serial plasma concentrations of the pyrogenic cytokines tumor necrosis factor and interleukin-1 beta were measured during treatment of acute renal allograft rejection with antithymocyte globulin in 7 consecutive kidney transplant recipients. TNF and IL-1 beta were measured with specific enzyme-linked immunosorbent assays. In 6 of 7 patients TNF could not be detected in the plasma before the start of the ATG infusion. During the first ATG infusion, which was accompanied by fever and other side effects in all patients, plasma TNF levels were shown to be elevated, ranging between 100 and 700 pg/ml. During the second ATG infusion, when side effects were minimal or absent, plasma TNF levels were only slightly raised. Circulating IL-1 beta could not be detected in any of the patients before or during ATG infusion. Additional experiments showed that TNF is rapidly secreted in cultures of peripheral blood mononuclear cells incubated with both ATG and the monoclonal antibody OKT3. These findings suggest that side effects, including fever and chills, during antilymphocyte antibody infusion are related to increased plasma levels of the pyrogenic cytokine TNF.

A bispecific antibody directed to T and B cells (CD3 x CD19 bsAb) was daily infused intravenously in escalating doses from 10 micrograms up to 5 mg in three patients with chemotherapy-resistant non-Hodgkin lymphoma; in this way we aimed to activate T cells to kill the malignant B cells. Only limited toxicity was observed, consisting of moderate fever preceded by chills or shivers and mild thrombocytopenia. No human anti-(mouse Ig) antibodies were found. Pharmacokinetics showed a t1/2 of 10.5 h with peak levels of 200-300 ng/ml after infusion of 2.5 mg bsAb. bsAb in serum was functionally active in vitro. After bsAb infusion a rise in serum tumour necrosis factor alpha was observed, accompanied by an increase in soluble CD8 and to some extent in soluble interleukin-2 receptor (IL-2R), but not in interferon gamma. IL-4 or soluble CD4. No evidence was found for monocyte activation (no increases in IL-6, IL-8 or IL-1 beta in serum). No gross changes in histology or number of IL-2R+, CD4+ or CD8+ cells were found in the lymph nodes after therapy, but one patient showed activated CD8+ T cells within the tumour nodules. In conclusion, after intravenously administered CD3 x CD19 bsAb only moderate toxicity was found, probably due to CD8+ T cell activation and cytokine release, without CD4+ T cell activation.

The administration of recombinant human interleukin-1 beta (rhIL-1 beta) stimulates pluripotent cell growth and reduces mortality from infection in animal models. In this phase I trial, rhIL-1 beta (0.02-0.50 microgram/kg) was administered by 30-minute intravenous infusion once daily for 2 or 5 consecutive days. The dose was escalated with the subsequent cycle in the same patient if no hematologic response was observed. Nineteen patients with severe bone marrow failure received 60 courses of IL-1 beta. Diagnoses included autologous bone marrow transplant (BMT) (n = 5), allogeneic BMT (n = 7) or idiopathic aplastic anemia (n = 6) and 1 patient with chronic myeloid leukemia. Toxicities included fever (89%), chills (85%), hypertension (89%), hypotension (57%) and headache (95%). No complications were life-threatening and all either spontaneously resolved or were managed pharmacologically. In 8 of 19 patients there was an acute, transient increase in neutrophil counts. In 2 patients there was a transient increase in platelet count; however, no durable, clinically significant effects on peripheral blood counts were observed. In conclusion, administration of rhIL-1 beta in this population of patients had limited efficacy and moderate toxicity.

Intravenous meperidine is commonly used to treat rigors and chills in febrile patients, though its mechanism of action is unknown. Therefore a laboratory model of pyrogen-induced fever was used to evaluate the effects of meperidine on the febrile response of rats injected with bacterial endotoxin or IL-1 alpha. Fever was measured using a computerized biotelemetry system for the continuous monitoring of body temperature. Injection of meperidine blocked the onset of fever in rats injected with endotoxin and attenuated the febrile response in rats injected with IL-1 beta. Furthermore, incubation of human mononuclear leukocytes (MNL) in the presence of meperidine significantly reduced endotoxin-induced secretion of IL-1 beta in vitro. These data suggest that meperidine decreases rigors and chills by decreasing the "set point" for fever, perhaps by reducing MNL secretion of IL-1 beta.

Administration of interleukin-1 beta (IL-1 beta) to humans initiates a cascade of metabolic, hematologic, and cardiovascular events. To investigate the role of the sympathetic nervous system in the early cardiovascular response to IL-1 beta in humans, we recorded the heart rate, blood pressure, and changes in hand vein compliance in five patients with malignant melanoma treated with a 30-min infusion of 10,000-20,000 U/kg of human recombinant IL-1 beta. All patients developed fever, chills, and marked hemodynamic changes. During or shortly after the infusion, a dramatic decrease in hand vein compliance occurred (vasoconstriction). At the time of maximum venoconstriction (35 min after the start of the IL-1 beta infusion), the mean heart rate and systolic blood pressure were significantly increased by 30 mm Hg and 31 beats/min, respectively. Venoconstriction always preceded the onset of chills by several minutes (mean of 7 min), was closely correlated with the heart rate, and could be reversed by local administration of the alpha-antagonist phentolamine, indicating involvement of catecholamines. Our study shows that cardiovascular responses that occur early after IL-1 beta administration in humans are most likely the result of adrenergic stimulation possibly through its effect on the central nervous system.

Normal volunteers received single doses of recombinant human interleukin-10 (rhIL-10; n = 6 per group) or placebo (n = 3 per group) by intravenous injection to characterize pharmacokinetics, tolerability, and immunomodulatory effects. Dosages were 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 25.0, 50.0, and 100.0 micrograms/kg. Dose-related adverse effects consisted of a mild-to-moderate flu-like syndrome characterized by fever with chills, headache, and myalgias at the highest dose. The mean terminal phase t1/2 ranged from 2.3 +/- 0.5 to 3.7 +/- 0.8 hours. Dose-related effects of rhIL-10 included transient increases of circulating neutrophils and monocytes and decreases of lymphocytes. rhIL-10 markedly suppressed, in a time- and dose-dependent manner, the synthesis of the inflammatory cytokines IL-1 beta and tumor necrosis factor alpha by whole blood stimulated ex vivo with bacterial lipopolysaccharide. Circulating numbers of CD14+/HLA-DR+ cells at 24 hours after the dose were increased in a dose-dependent manner. Effects on expression of HLA-DR by CD14+ cells were variable. There was no apparent effect on HLA-DR expression by CD20+ cells. The immunomodulatory effects of rhIL-10 merit further clinical investigation.

Eighteen advanced cancer patients received weekday subcutaneous injections of recombinant interleukin-6 (rIL-6) for 4 weeks at escalating doses. Patients were evaluated for hematologic and immune system effects. Hematologic monitoring included WBC, differential, Hgb and Hct, platelet counts, and assessment of marrow and peripheral blood progenitors. Immunologic monitoring included evaluation of acute-phase reactants (APRs), immunophenotyping, serum cytokine levels, cytokine-induced proteins, and cytokine messenger RNA (mRNA). The maximal tolerated dose (MTD) was 8.0 micrograms/kg/day, with neurocortical toxicity as the major limiting factor. All patients became anemic, and most had fever and chills. APRs were increased throughout treatment. WBCs increased transiently on day 2; granulocytes and monocytes increased again through day 26, whereas lymphocytes decreased to baseline or lower levels. Platelets responded by day 12 and increased through day 26 at the MTD with no effect on colony-forming unit-megakaryocyte (CFU-Mk). Peripheral WBC and RBC progenitors were not affected but decreased in the marrow. T-cell percentages declined with little effect on absolute numbers; T-cell activation was seen. CD45RO+ T cells decreased, but there was no significant effect on CD8+ CD28+ T cells. Neither B cells nor natural killer (NK) cells were affected. However, evidence of monocyte effects included upregulation of CD71, induction of the cytokine-induced proteins 2-5A synthetase and neopterin, and increases in tumor necrosis factor-alpha (TNF-alpha) mRNA. Serum cytokines were undetected, and mRNA for IL-1 beta, IL-2, and interferon-gamma (IFN-gamma) was not induced; however, mRNA for IL-4 and IL-10 did increase suggesting activation of Th2-like T cells. One mixed tumor response was seen. We conclude that IL-6 alone has systemic activity on the immune system, as well as the hematopoietic system, which at the MTD, primarily involves induction of APR, activation and expansion of monocytes, and activation of Th2-like T cells.

Effects of soluble recombinant human type I interleukin-1 receptor (sIL-1RI) were evaluated in 18 volunteers given intravenous endotoxin and randomized to placebo (n = 6), low-dose (n = 6), or high-dose (n = 6) sIL-1RI. Soluble IL-1RI decreased IL-1 beta (P = .001), but decreased IL-1ra (P = .0001), and resulted in 10-fold and 43-fold dose-related increases in sIL-1RI-IL-1ra complexes compared with placebo (P < or = .001). High-dose sIL-1RI was associated with increased levels of immunoactive tumor necrosis factor-alpha (P = .02), IL-8 (P = .0001), and cell-associated IL-1 beta (P = .047). C-reactive protein levels were higher after sIL-1RI than placebo (P = .035). Soluble IL-1RI decreased the severity of chills (P = .03), but did not alter other symptoms, changes in temperature, systemic hemodynamic responses, or changes in leukocyte and platelet number. Thus, sIL-1RI had no discernable antiinflammatory effect following endotoxin administration due in part to low levels of circulating IL-1 beta and neutralization of IL-1ra inhibitory function. This latter interaction represents an indirect mechanism of agonist activity elicited by sIL-1RI and may contribute to increases in inflammatory mediators, limiting therapy with sIL-1RI during endotoxemia.
