Muramyl tripeptide phosphatidylethanolamine (MTP-PE; CGP 19835A from Ciba Geigy) is a synthetic muramyl tripeptide structurally related to bacterial cell wall constituents. MTP-PE activates monocytes in vitro to a tumoricidal state and has in vivo antitumor effects in animal models. We studied the toxicity and immunomodulatory effects of once weekly i.v. administration of liposomal-encapsulated MTP-PE for 8 weeks in 27 patients with advanced malignancies. Doses ranged from 0.1 to 2.7 mg/m2. No major tumor responses were seen; 11 patients had stable disease after 8 weeks of therapy and 3 continued on maintenance therapy because of minor tumor regressions and/or clinical improvement. MTP-PE at these doses was well tolerated. Shaking chills and fevers were the most common toxicities and occurred at all dose levels. There was no treatment-induced loss of performance status. Immunomodulatory studies revealed evidence of a biological effect on monocytes. C-reactive protein levels rose in the majority of patients with end-of-treatment values 2 to 10 times higher than baseline. Serum neopterin levels were consistently increased 24 h after MTP-PE administration and significant decreases in expression of two different types of Fc receptors on peripheral blood monocytes were noted 6 h after treatment. Although no major tumor responses were seen in this group of patients with advanced malignancies, MTP-PE was well tolerated and exerted biological effects on monocytes. Serum neopterin levels may be a useful marker for the biological effects of MTP-PE.

This study sought to determine whether endogenous tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and granulocyte-colony-stimulating factor (G-CSF) were detectable in sera of lipopolysaccharide (LPS)-treated cancer patients. Twenty patients received an intravenous bolus of purified LPS from Salmonella abortus-equi (4.0 ng/kg). Patients were pretreated with ibuprofen (1,600 mg) to prevent constitutional side effects like fever and chills. Serum TNF-alpha levels increased from less than 0.01 ng/ml before treatment up to maximal levels of 21 ng/ml, peaking 1.5 h after LPS injection. Similarly, serum IL-6 concentrations increased from less than 0.01 to 11 ng/ml, but peak levels were obtained 30 min later than TNF-alpha. Circulating G-CSF appeared still later than TNF-alpha and IL-6. It was detectable within 3 h and peaked 6 h after LPS injection. Parallel to the release of the above cytokines a marked increase in granulocyte counts was observed. In all patients administration of LPS led to an acute-phase response as measured by C-reactive protein.

The effect of treatment with a monoclonal antibody against the CD4 antigen present on T helper cells was studied in 10 patients with severe intractable rheumatoid arthritis. In an open trial, monoclonal antibody 16H5 was infused at a dosage of 0.3 mg/kg of body weight on 7 consecutive days. Studies of the kinetics demonstrated a drastic depletion of CD4+ cells, to as low as 25 cells/microliters, 1 hour after the first infusion. The subsequent recovery of the CD4+ cell numbers 24 hours after infusion did not reach initial levels, and after the full 7-day treatment cycle there was a significant reduction of the number of CD4+ cells (mean +/- SD 51 +/- 28%; P less than 0.02). There was a reduced or even inverse CD4:CD8 ratio, which generally persisted 3-4 weeks. Lymphocyte transformation assays demonstrated significantly reduced reactivity in 5 of the 9 patients who completed the 7-day course, whereas 4 individuals exhibited an unexpected elevation in the T cell response to mitogens and common antigens. Parallel laboratory studies showed a significant decrease in the erythrocyte sedimentation rate (P less than 0.05), rheumatoid factor titer (P less than 0.04), and total immunoglobulin values (P less than 0.01), as well as a reduction in C-reactive protein levels, in 7 of the 9 patients. Clinically, there was a significant reduction in the Ritchie articular index (P less than 0.05) and in the number of swollen joints (P less than 0.04). Adverse effects were urticaria in 2 patients, which led to withdrawal of therapy in 1 of them, and chills with fever, suggestive of a lymphokine release syndrome, in another 2 patients. Only low levels of human anti-mouse immunoglobulin antibodies developed (not exceeding 1.7 mg/liter). It was therefore possible to repeat the treatment cycle, achieving still better efficacy, in 4 of the patients (reductions in the Ritchie index and the number of swollen joints P less than 0.02). Our findings indicate that treatment with monoclonal antibodies against the CD4 antigen leads to immunomodulation which results in clinical benefits, at least during initial observation periods (up to 6 months postinfusion). However, it remains to be determined whether long-term remission can be induced with this therapeutic approach. The use of immunosuppressive therapies or repeated antibody treatments will have to be considered.

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.

Since it is very rare that cardiac tamponade due to myocardial rupture caused by infective endocarditis, occurs we are reporting this case. A 62 year old man, who had underlying diseases of pneumoconiosis and hypertensive heart disease, visited Chikuho Rosai Hospital complaining of chest oppression and general fatigue on Feb. 7, 1987. He was diagnosed as having ischemic heart disease by electrocardiogram. Two days later, he suddenly had chills and a fever, and the laboratory data showed leukocytosis and a positive C-reactive protein (CRP). The echo cardiogram showed mitral regurgitation (MR) and aortic regurgitation (AR), but neither vegetation nor pericardial effusion was observed. On Feb. 16, he was admitted with shock, and he died the next day. The blood cultures grew gram-positive cocci, respectively. From the clinical symptoms, chest roentgenogram and electrocardiogram, we suspected a cardiac tamponade. On autopsy findings, though coronary arteries were intact, the aortic valves had severe valvular adhesions, calcifications and hypertrophies. The rupture hole was observed in the left ventricles, which was just under the aortic valve through the pericardiac space. It seemed that he died of a cardiac tamponade due to the outflow of blood from this hole. On histopathologic findings of the cardiac wall, gram-positive cocci and many of neutrophils were observed.

The purpose of the study was to evaluate the toxicity and biological activity of highly purified lipopolysaccharide (LPS) administered intravenously to cancer patients in order to establish an optimum dosage scheme. An initial subtoxic dose was increased in weekly increments in accordance with individual regimens that maintained patient reaction at a safe and acceptable level. Purified LPS from Salmonella abortus equi was administered to 11 patients with advanced solid tumors on a weekly schedule with intraindividually escalating dosage as determined by patient response. Biological response was monitored by complete blood count, C-reactive protein, and cytokine measurements at different time points after LPS injection. Tumor necrosis factor-alpha (TNF) and interleukin-1 beta serum levels were measured by enzyme-linked immunosorbent assay and interleukin-6 (IL-6) by bioassay. Dose-limiting toxicities including chills and fever (WHO grade III) were reached at 1.0 ng/kg of body weight (maximal tolerated dose-1, MTD-1). Pretreatment with ibuprofen (1,600 mg) abrogated these side effects, allowing further escalation of LPS doses up to 10 ng/kg of body weight. At dose levels greater than 8.0 ng/kg of body weight (MTD-2), the aforementioned side effects occurred again and, additionally, hepatic toxicity (WHO grade III) was observed. Hematological changes included neutropenia followed by a pronounced neutrophilia contributed to by up to 30% bands, marked monocytopenia for 3 h, and retarded lymphopenia. By 24 h, all hematological parameters returned to pretreatment values. TNF serum levels increased from 10 pg/ml before treatment to 7,000 pg/ml as a function of dosage. Maximum serum levels were reached at 60 to 90 min after LPS injection. Similarly, IL-6 serum concentrations increased from less than 4 to 2,500 U/ml; peak levels were obtained 30 min after TNF peak values. Prior administration of ibuprofen had no effect on the above-mentioned hematological changes nor on cytokine release. LPS can be administered intravenously in weekly intervals at escalating doses from 0.15-10.0 ng/kg of body weight, when patients are protected by pretreatment with ibuprofen at dose levels above 1.0 ng/kg of body weight. Cytokine release as measured by TNF and IL-6 increased in a dose-dependent manner although the constitutional symptoms are completely attenuated.

Although the clinical effects of acute exposure to ultraviolet (UV) light--such as cutaneous inflammation, malaise, somnolence, chills and fever--have been appreciated many years, the underlying mechanisms mediating these effects are poorly understood. Interleukin-6 (IL-6) is a potent cytokine with a wide variety of biologic activities, including induction of fever and acute phase response. Because IL-6 is produced by keratinocytes in vivo and in vitro and because the release is enhanced by UV light, the present study was performed to investigate the effect of a single UV dose eliciting moderate to severe sunburn reaction on the production of IL-6 in vivo. Therefore, plasma of UV-treated human subjects was evaluated for IL-6 activity by testing its capacity to induce the proliferation of an IL-6-dependent hybridoma cell line (B9). In contrast to plasma samples obtained before UV exposure, post-UV-specimens contained significant levels of IL-6 peaking at 12 h after UV irradiation. Plasma IL-6 activity was neutralized by an antiserum directed against recombinant human IL-6, and upon HPLC gel filtration exhibited a molecular weight of around 20 kD. Moreover, plasma IL-6 levels correlated remarkably with fever course followed by an increase of acute phase proteins such as C-reactive protein. These data indicate that IL-6, which is released by keratinocytes following UV exposure, may gain access to the circulation and via its pyrogenic as well as acute phase-inducing effect may function as an important mediator of systemic sunburn reaction.

Seventeen patients with refractory malignant tumors were treated with recombinant human interleukin-2 (IL-2) administered by weekly bolus intravenous (IV) injection in a phase I dose escalation trial. Patients received 10,000 to 1,000,000 U/m2 per injection over a course of 3 to 33 weeks. Toxicity was dose related and consisted primarily of fever, chills, nausea, and vomiting. Hypotension was observed at doses of 500,000 U/m2 or higher and in one instance was sufficiently severe to require pressors. No tumor regression was seen and all patients eventually developed progressive disease. Blood levels of cortisol, ACTH, prolactin, and growth hormone as well as the acute phase reactant C-reactive protein (CRP) increased after the administration of IL-2 in most patients. Serum IL-2 levels in excess of 250 U/mL were detected five minutes after an IV injection of 1,000,000 U/m2, after which the levels declined with a half-life of approximately 25 minutes. No alteration in lymphocyte surface phenotype or enhancement in natural cell-mediated cytotoxicity against natural killer (NK)-sensitive and resistant tumor cell lines was observed when these parameters were measured weekly just before the IL-2 injections. However, a dramatic but transient decline in circulating lymphocytes and NK activity was noted within hours of receiving IL-2. This effect was independent of fever and was not abrogated by pretreatment with ibuprofen or metyrapone. The majority of patients developed serum IgG antibodies of IL-2 detectable with a sensitive enzyme-linked immunosorbent assay (ELISA) and a nitrocellulose dot blot assay. The development of anti-IL-2 antibodies was not associated with symptoms suggestive of serum sickness, reductions in serum complement levels, or deterioration in lymphocyte tumoricidal activity. This investigation provides insight into the in vivo actions of this potent biological response modifier and will assist in the design of future studies with IL-2 administered alone or in conjunction with other treatment modalities.

Of 452 patients with brucellosis, 169 (111 male and 58 female) had osteoarticular complications. Brucella melitensis was isolated from the blood in 7.7% of the cases. Fever, chills, arthralgia, backache, high levels of C-reactive protein, positive rheumatoid factor, and splenomegaly were more frequent in osteoarticular brucellosis than in nonosteoarticular disease. Arthritis occurred in the hip joint in 90 cases (53%), knees in 61 (36%), sacroiliacs in 33 (20%), ankles in 25 (15%), elbows in nine (5.3%), shoulders in eight (5%), wrists in six (3.5%), and sternoclavicular arthritis occurred in three cases (1.8%). Spondylitis occurred in 10 cases (6%), osteomyelitis in four (2.4%), and tendinitis or bursitis in two (1.2%). Treatment with tetracycline or trimethoprim-sulfamethoxazole (TMP-SMZ) alone (four to eight weeks) or in combination with streptomycin (two to four weeks) resulted in a relapse rate of 16.6%. No relapses occurred in seven patients treated with repeated four- to six-weeks courses of rifampin plus tetracycline or TMP-SMZ plus streptomycin.

A 26-year-old man who had suffered from intermittent chills and fever over a two month period was quite clear of heart or kidney involved developed acute deterioration of renal function. A new pansystolic murmur over the apex of the heart was heard on auscultation, and echocardiography clearly showed a vegetation about 0.7-0.9 cm in size on the atrial site of the mitral value. Laboratory investigation displayed normochromic anemia with negative Coombs' test. Immunological studies were positive for rheumatoid factor and circulating immune complex. High serum levels of erythrocyte sedimentation rate and C-reactive protein, nephritic sediment of urinalysis and negative blood cultures for bacteria, tuberculosis or fungus were also noted. Abdominal sonography showed normal kidney size, bilaterally. Renal biopsy revealed typical crescentic glomerulonephritis. After intravenous penicillin therapy for two weeks, the serum creatinine level recovered from 6.7 mg/dl to 2.0 mg/dl and circulating immune complex disappeared. In consideration of cardiac insufficiency and the potential risk for complications of the vegetation, the patient underwent mitral valve replacement. Four weeks after operation, all the abnormal data had resolved completely. These data suggested that infective endocarditis with rapidly progressive glomerulonephritis is curable by antibiotic therapy and surgical intervention.
