The purpose of this phase I study was to evaluate the toxicity and biological activity of autologous blood-derived macrophages activated ex-vivo with recombinant human interferon gamma (rhuIFN gamma) [monokine-activated killer (MAK) cells] and administered intravenously to 11 lung cancer patients once a week for 6 consecutive weeks. Peripheral blood monocytes were collected by leukapheresis and then purified by counterflow elutriation. The MAK cells were generated by culturing the purified monocytes in Teflon bags for 7 days and adding rhuIFN gamma to the cultured cells for the last 18 h. These MAK cells expressed differentiation-associated surface antigen MAX1, and were cytotoxic in vitro against tumour cell line U937. The MAK cells were infused at dose levels from 1 x 10(7) to 5 x 10(8) on an intrapatient dose-escalating schedule. No severe adverse side-effects occurred. Toxicity was mild to moderate [primarly fever (75%) and
chills
(32%)], non-dose-dependent, and non-cumulative. No consistent change in haemostatic function, or liver or renal function was observed. Dose-limiting toxicity was not reached at 5 x 10(8) cells (optimal dose reproduced for each patient). The maximum tolerated dose was not determined. The immunomodulatory activity of i.v. infused MAK cells was demonstrated both in vivo by significant increases in granulocyte count and neopterin level in the patients' peripheral blood post-infusion and in vitro by secretory products (
IL-1
. TNF alpha, neopterin, and thromboplastin-like substance) in the culture supernatants. The in vivo traffic patterns of autologous MAK cells labelled ex-vivo with 111In oxine were studied in 7 patients. Gamma imaging showed an immediate but transient lung uptake (less than 24 h), and a progressive uptake of radioactivity in the liver and spleen was seen from 6 h to 72 h post-infusion. Our results indicate that the preparation of high numbers of autologous, blood-derived MAK cells is a feasible procedure, and their transfusion is safe for patients. This immunotherapeutic approach seems to be encouraging from the point of view of establishing an adjuvant therapeutic modality in cancer patients with minimal residual disease.

We have conducted a phase I study with autologous monocytes activated ex vivo and administered intraperitoneally in nine patients with peritoneal carcinomatosis. Blood monocytes were collected by leukapheresis and then purified by counterflow elutriation (up to 10(9) cells, with a purity of greater than 90%). Ex vivo activation was obtained by incubating these cells with 1 micrograms liposomal MTP-PE/10(6) monocytes for 18 hours in hydrophobic culture bags at 37 degrees C in 5% carbon dioxide humidified air. The activated monocytes were then infused in the peritoneal cavity once a week for 5 consecutive weeks through an implanted peritoneal infusion system, Port-A-Cath (Pharmacia Deltec, St Paul, MN), on an intrapatient dose-escalating schedule (10(7) to 10(9) monocytes). No severe adverse reactions occurred. Toxicity was mild, the chief acute reactions being fever (27%),
chills
(13%), and abdominal pain (25%). None of the side effects led to dose reduction. No consistent change in hemostatic function, liver function, or renal function was observed. Significant increases in granulocyte counts, neopterine, and acute phase reactants (fibrinogen, C-reactive protein) occurred in the peripheral blood. In vitro monocyte activation was demonstrated by the relapse of procoagulant activity and monokines (interleukin-1 [
IL-1
], IL-6, and tumor necrosis factor-alpha [TNF alpha]) in the supernatants of cultured monocytes. Evidence for in vivo monocyte activation was provided by the increase of these monokines in the peritoneal fluids. Kinetic studies with indium-111 (111In)-labeled activated autologous monocytes in five patients suggest that these infused monocytes may remain in the peritoneal cavity for up to 7 days. This locoregional immunotherapeutic approach seems to be encouraging in view of adjuvant therapeutic modality in ovarian cancer patients with minimal residual intraabdominal disease following second-look laparotomy.

Ultraviolet (UV) radiation is a significant environmental hazard for humans and animals. Although the clinical effect of an acute UV exposure such as cutaneous inflammation, malaise, somnolence,
chills
, and fever have been appreciated for many years, the underlying mechanisms mediating these effects are poorly understood. Since
chills
and fever are the most dramatic systemic sequelae after a prolonged exposure to UV, we specifically examined the effect of whole-body UV irradiation on core body temperature and serum endogenous pyrogen activity of New Zealand White rabbits, correlating this with serum
interleukin 1
(
IL-1
) activity and alterations of serum divalent cation levels. We found that an acute dose of UV irradiation (Westinghouse FS-40 lamps, 0.2 mJ/cm2/s X 8 h) resulted in a significant increase in the core body temperature 2 h post UV (0.8 degree C), peaking 5 h post UV (1.8 degree C), and returning to normal 24 h post UV. Likewise, the sera from the UV-irradiated rabbits had significant endogenous pyrogen activity when transferred into naive recipient animals, causing an increase in core body temperature within 45 min (0.65 +/- 0.12 degree C), decreasing over the next 2 h, and returning to normal 6 h post injection. No endotoxin contamination was detected in any serum samples. This post-UV febrile response was accompanied by a prolonged increase in serum
IL-1
activity (5-10 X) and a significant alteration in serum divalent cation levels, with the rabbits becoming euthermic even as the serum
IL-1
levels remained elevated. These findings provide new information concerning the pathogenesis and kinetics of these systemic effects after an acute dose of UV irradiation.

Cells of the monocyte/macrophage lineage have shown antitumor activity in vitro and in murine models after activation with interferon (IFN) gamma. In vitro data suggest an additional effect on macrophage antitumor activity when IFN gamma is combined with endotoxin (lipopolysaccharides; LPS). In this study we treated nine cancer patients with a total of 62 MAK infusion cycles with autologous macrophages given intravenously (i.v.) after in vitro activation with IFN gamma and LPS. Low-grade fever (WHO I/II) was the commonest side-effect.
Chills
, nausea, and headache were noted when the number of transfused macrophages exceeded 2 x 10(8). One WHO IV toxicity occurred, consisting of hypotension after transfer of 3 x 10(8) cells, defining this dose as the maximum cell number tolerated. After pretreatment with ibuprofen, however, the maximum cell number could be increased without reaching dose-limiting toxicity. The highest number of cells reinfused was 15 x 10(8). Circulating interleukin(IL)-6 increased in a dose-dependent manner as did
IL-1
receptor antagonist (IL-1RA) and IL-8. Tumor response consisted of one case of stable disease (12 weeks) in a patient with formerly progressing colorectal cancer and progressive diseases in eight patients. This study indicates that reinfusion of autologous LPS-activated macrophages upon pretreatment with ibuprofen is feasible and tolerated without major side-effects.

Amphotericin B is an antifungal drug associated with side effects such as fever and
chills
, symptoms which may be mediated by pro-inflammatory cytokines such as interleukin-1beta (IL-1beta) and tumour necrosis factor-alpha (TNFalpha). We assessed the capacity of amphotericin B to modulate production of these pro-inflammatory cytokines as well as the anti-inflammatory
IL-1
receptor antagonist (IL-1ra), induced by LPS, heat-killed Candida albicans or Staphylococcus aureus. The results of the present study show that amphotericin B slightly increased the production of pro-inflammatory cytokines by human mononuclear cells (PBMC), whereas the production of the anti-inflammatory cytokine IL-1ra was significantly inhibited. This results in a shift towards pro-inflammatory cytokine production, as indicated by a decreased IL-1ra/IL-1beta ratio. Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) indicated that levels of IL-1beta and TNFalpha mRNA were increased. In conclusion, amphotericin B is able to cause a shift towards pro-inflammatory cytokine production by human PBMC. This may explain the side effects, such as fever and
chills
, observed after treatment of patients with amphotericin B.

A vaccine consisting of four allogeneic colon carcinoma cell lines (DLD-1, HCT116, WiDr, and T84) mixed with the adjuvant DETOX (Mycobacterium phlei cell wall and Salmonella minnesota lipid A) was administered to 25 patients with low-volume metastatic colorectal carcinoma. The first eight patients received vaccine only, given intradermally on three occasions at 3-week intervals. Subsequent patients also received subcutaneous interleukin-1 alpha (IL-1 alpha), 0.3-0.5 microgram/m2 per day for 8 days after each vaccination in an outpatient setting. Vaccine alone caused local erythema, induration, and pruritus.
IL-1
caused fevers,
chills
, and rigors that started in 4 h and lasted 1-2 h. One patient developed a brief loss of consciousness with a rigor that resolved without sequelae. One episode of mild hypotension occurred. Fatigue occurred by day 8 of
IL-1
. A substantial increase in the number of patients with positive skin tests to DLD-1 and HCT116 occurred after vaccine treatment both without and with IL-1 alpha. An allogeneic cell vaccine plus subcutaneous
IL-1
was administered safely to outpatients with some evidence of in vivo effect observed.

The etiologic hantavirus of the 1993 emergence of an acute pulmonary failure syndrome in the area around northwestern New Mexico was quickly recognized as related to the Hantaan virus responsible for the outbreak of Korean epidemic hemorrhagic fever (EHF) among UN troops in 1951. Discovery of the new disease which was named the hantavirus pulmonary syndrome (HPS) and its causative agent the Sine Nombre virus (SNV) inspired detailed comparisons between the two disorders. Major damage to the epithelial cells of the capillaries and arterioles throughout the body leading to extensive capillary leak and subsequent hypotension and shock was the common denominator. The lung capillaries and arterioles were the focus of attack that could lead to rapid pulmonary failure in HPS and the corresponding renal and retroperitoneal vessels that caused a more protracted illness in EHF, but both displayed remarkably similar peripheral blood abnormalities including abnormal mononuclear cells, immature neutrophilia, thrombocytopenia, and hemoconcentration characteristic enough to make blood smear examination a useful tool in early diagnosis. There are evidences that a heavy virus presence in the involved endothelial cells is accompanied by various mononuclear cells capable of generating potent immune response in these areas. Relevant toxic effects of systemically-administered high-dose interleukin-2 for resistant cancers include fever,
chills
, diarrhea, renal dysfunction, capillary leak syndrome accompanied by hypotension requiring aggressive pressor support, and occasional pleural effusions with diffuse pulmonary infiltrates and hypoxia severe enough to require ventilatory assistance. Peripheral blood mononuclear cells cultured in vitro with IL-2 secrete secondary cytokines such as
IL-1
, TNF-alpha, and interferon-gamma (IFN-gamma). TNF-alpha, implicated in the pathophysiology of septic shock, is capable of inducing adult respiratory distress syndrome (ARDS) in experimental animals and humans. The strong similarity of these effects to the manifestations noted in the hantavirus diseases justifies the conviction that these and other cytokines involved in potent immune responses would constitute the pathogenic toxic substances predicted by perceptive early investigators of EHF. This concept is favored by clear indications that in both diseases active virus infection disappears the first few days and the ages of involvement correlate with periods of immunocompetence. The paradox of systemic injections of IL-2 that risk hantavirus-type toxicities for treating renal cell carcinoma and melanoma might be avoided by giving potentially more efficacious plant mitogens like PHA as previously reported. The expanded disclosure of a collaborator's method suggesting superior potential for cancer cure involves a unique application of pokeweed mitogen that delivers various cellular and cytokine responses directly to the tumor.

In spite of proven immunoregulatory effects in vitro of recombinant human interferon-gamma (rhIFN-gamma) in trauma, clinical trials remain inconclusive in such patients. To investigate the in vivo effect of rhIFN-gamma perioperatively in surgical patients we did a pilot study in 46 patients termed anergic by negative delayed-type hypersensitivity (DTH) skin test, who were undergoing major surgery (22 women and 24 men). They received 100 micrograms of rhIFN-gamma subcutaneously (treated [T]; n = 24) in a double-blind, placebo- (control [C]; n = 22) controlled manner on preoperative days -7, -5, and -3. Whole-blood cultures were stimulated on days -7, -1, 4, 7, and 10 for 12 h with or without LPS (1 microgram/mL). Mild side effects such as fever, headache, or
chills
were observed in 7/24 patients. No major complications occurred and no significant effect of rhIFN-gamma on HLA-DR,
IL-1
, and IL-8 was demonstrated. PGE2, TNF-alpha and IL-6 levels were elevated perioperatively in T. versus C. Neopterin, a metabolite of activated monocytes and macrophages, was significantly activated on days -1 (C: 7.6 +/- 1.2 versus T: 20.5 +/- 2.4 nmol/mL; P < 0.001), day 1 (C: 8.3 +/- 1.4 nmol/mL versus T: 24.9 +/- 2.8 nmol/mL; P < 0.001), and day 4 (C: 9.5 +/- 1.1 nmol/mL versus T: 16.0 +/- 1.8 nmol/mL; P < 0.05). Due to the overall lack of infectious complications during the investigation, no clinical effect was shown for rhIFN-gamma treatment. DTH skin testing failed to detect high-risk individuals in the patient population studied. In conclusion, we demonstrated in our pilot study that pre-operative immunomodulation with rhIFN-gamma in surgical anergic patients did not show severe side effects and modulated in vitro immunoresponse. A larger clinical trial in better-defined high-risk patients may show whether a reduction of infectious complications can be achieved.
