We have used an antihuman tumor necrosis factor monoclonal antibody, CB006 (murine IgG1), to prevent the OKT3-induced acute clinical syndrome. This syndrome is due to the massive, although transient release in the circulation of various cytokines (TNF, interferon gamma, interleukin 2, interleukin 6) and represents one important side effect linked to in vivo use of OKT3. Fourteen kidney allograft recipients undergoing prophylactic OKT3 therapy were treated with CB006 in a single i.v. injection of either 0.4 mg/kg (group I, 7 patients) or 2 mg/kg (group II, 7 patients), 1 hr before the first OKT3 administration. Nineteen consecutive patients formed a historical control group. None of the CB006-pretreated patients showed any of the common, severe OKT3-associated symptoms (hypotension, respiratory distress, or neurotoxicity), which were observed in 10% of the historical controls. In addition, CB006-treated patients showed a lower frequency of pyrexia (> or = 39 degrees C) and gastrointestinal symptoms. None of the CB006-treated patients presented severe vomiting or diarrhea, defined as repeated episodes inducing significant fluid and electrolyte loss. Two out of the 7 patients in group I and group II had mild transitory diarrhea. Mild single vomiting episodes occurred in 2 group I patients and 3 group II patients. At variance in all controls, gastrointestinal symptoms were long lasting and associated with major prostration due to electrolyte and fluid loss. Importantly, CB006-treated patients who presented mild symptoms had detectable bioactive circulating TNF, showing incomplete inactivation of OKT3-induced TNF by CB006. CB006 was perfectly well tolerated, did not induce xenosensitization, and did not affect the biological or clinical effectiveness of OKT3.

Many drugs are applied in local treatment for skin malignant tumors. These drugs are living-BCG, OK-432, MY-1, WPG, interferon preparation (alpha, beta and gamma), TNF, IL-2, peplomycin, bleomycin and others. Some of them already have completed clinical trials and others are under clinical observation. In local administration of these drugs, skin lesions (malignant melanoma, CTL-mainly mycosis fungoides, carcinoma in situ and others) show good improvement. The effects were more observed in the tumors with diameters of 1 cm or less and appeared 3 to 10 injections in most cases. As complications, there are fever, general fatigue, vomiting, anorexia, leucopenia and others. Among them, the fever was most observed immediately after injections without any more severe complications. It may be concluded that treatment by intratumoral administration is useful for skin malignant tumors.

Based on a phase I study in 1986, 22 patients have been entered in a phase II study of high-dose human tumor necrosis factor (rH-TNF) since May 1987. Of these patients, 18 are evaluable at present, 2 are still under investigation, and 2 have dropped out. All had advanced stages of cancer (9 soft-tissue sarcomas, 3 melanomas, 5 hypernephromas) and inclusion in the study was ethically acceptable (informed consent). The daily dose of rH-TNF was 15 x 10(5) units/m2, escalated to 21 x 10(5) units/m2 (683-956 micrograms/m2 every week; range 1-6 cycles). Additional prophylactic ketoprofen administration was carried out. Of the 18 evaluable patients, 4 responded with no change (2/4, clinical improvement) and 14 showed progressive disease. The main toxicities observed were hypotension (decrease in systolic blood pressure, 21-60 Torr), leukocytosis, increases in ALAT/ASAT (WHO grade 0-4), fever (WHO grade 1-2), chills (mild to moderate), neurotoxicity (WHO grade 0-2), and nausea/vomiting (WHO grade 0-3).

Nineteen patients with advanced cancer for which there was no effective standard therapy or whose disease was refractory to standard therapy were treated with recombinant tumor necrosis factor (rTNF). The rTNF was administered subcutaneously for 5 consecutive days every other week for 3 treatment weeks. The doses administered ranged from 5 micrograms/m2/day to 150 micrograms/m2/day. There was no intrapatient dose escalation. Systemic side effects of chills, fever, hypotension, nausea, vomiting, and headache were mild and self-limiting. At the maximum tolerated dose of 150 micrograms/m2/day, five of seven patients experienced moderate to severe thrombocytopenia. Mild rapid declines in total leukocyte count occurred within 60-90 min of administration of the drug, followed by a rise in the total leukocyte count by 120 min. When the total daily dose was administered in a single subcutaneous site, skin ulceration and necrosis occurred at the 100 micrograms/m2/day dose. By giving the total daily dose in two subcutaneous sites, the maximum tolerated dose increased to 150 micrograms/m2/day, and there was no further skin ulceration or necrosis. Skin necrosis occurred in the abdomen and thigh but not on the upper extremity at the 100 micrograms/m2/day dose given in a single site. There was no other significant organ toxicity. No rTNF was detectable in the serum even at the highest doses. No antibodies to TNF developed in any of the patients. The recommended dose of rTNF for Phase II trials given for 5 days subcutaneously is 150 micrograms/m2/day divided into two or more sites.

A Phase I study of rHu-TNF (PT-050) was conducted in patients with various malignant tumors refractory to conventional therapy. rHu-TNF was administered by 30-min intravenous (i.v.) infusion or intratumor (i.t.) injection. The starting dose of 1 X 10(5) U/body was increased to 5 X 10(6) U/body in the i.v. group and to 2 X 10(6) U/body in the i.t. group. rHu-TNF was evaluated in 41 patients among the enrolled 43 patients of the i.v. group, and in 9 out of 10 in the i.t. group. In the i.v. group, fever (68.3%), chills (75.6%), hypotension (46.3%), general fatigue (34.1%), nausea/vomiting (22.0%/22.0%), pain in the extremities (17.1%), etc. were observed as adverse reactions (ADRs), and elevation of GOT/GPT (46.3%/43.9%), elevation of ALP(26.8%)and decrease in platelets (12.2%), etc. were observed as abnormal laboratory findings. Among these, hypotension was recognized as the dose-limiting factor and the maximum tolerated dose was considered to be 1 X 10(6) U/body. Plasma levels of rHu-TNF after 30-min i.v. administration were dose-related, and decreased with half-lives of 0.5-2.4 hours. In the i.t. group, ADRs occurred with a lower incidence than in the i.v. group except for fever, chills and general fatigue. Plasma levels after i.t. administration were all within the assay limit. Evident tissue necrosis was observed in the region where rHu-TNF was administered in the i.t. group.

A phase I study of recombinant human tumor necrosis factor (rHu-TNF:PT-050) given by intravenous infusion over 30 min or by intratumoral administration was performed in 53 patients with various types of malignant tumors. The dose of rHu-TNF was started with 0.1 x 10(6) U/body for both intravenous infusion and intratumoral administration and increased to 5 x 10(6) U/body for intravenous infusion and 2 x 10(6) U/body for intratumoral administration. The side effects of rHu-TNF given by intravenous infusion included fever, shaking chills, hypotension, general malaise, nausea, and vomiting, and clinical laboratory tests showed elevations of GOT, GPT, and ALP, etc. Among these, only hypotension was dose-related and was considered to be a dose-limiting factor. The maximum tolerable dose estimated was 1 x 10(6) U/body. The plasma concentration of rHu-TNF after completion of a 30-min infusion was dose-dependent, and the elimination half-life was 0.5-2.4 hr. When the rHu-TNF was administered intratumorally, the frequency of side effects was low compared with intravenous infusion.

The hyper-IgD syndrome is a rare entity characterized by early onset of attacks of periodic fever. All patients have an elevated serum IgD (> 100 U/ml). Symptoms during attacks include joint involvements (arthralgias/arthritis), abdominal complaints (vomiting, pain, diarrhoea), skin lesions, swollen lymph nodes, and headache. In 1992 an International hyper-IgD study group was established, and to date the diagnosis has been made in 60, mainly European patients; 14 come from France. The disorder occurs in families and is transmitted by autosomal recessive inheritance. Linkage studies indicate that the gene encoding for familial Mediterranean fever is different from the gene for the hyper-IgD syndrome. In children the hyper-IgD syndrome should be distinguished from two other periodic febrile disorders. CINCA (chronic inflammatory, neurological, cutaneous and articular syndrome) and FAPA (periodic fever, adenopathies, pharyngitis, and aphtous stomatitis) share some symptoms with the hyper-IgD syndrome but in these syndromes serum IgD is normal. The pathogenesis remains to be elucidated but during attacks all patients have an acute-phase response with elevated C-reactive protein concentrations. During the febrile episodes, the inflammatory cytokines such as IL-6 TNF alpha, IFN gamma are increased together with natural occurring inhibitors such as IL-1ra and sTNFr. There is no therapy for the syndrome and patients will experience attacks during their entire life although frequency and severity tend to diminish with age.

The use of OKT3 as an immunosuppressive agent is accompanied by increased cytokine production and constellation of side effects collectively termed cytokine release syndrome (CRS). Pentoxifylline (PTF) inhibits synthesis of some cytokines, and has been shown to attenuate CRS when administered before OKT3. In this double-blinded, placebo-controlled study, 46 renal allograft recipients were randomized to receive either PTF (800 mg q 8 hr for at least 24 h) p.o. or placebo, along with methylprednisolone (7 mg/kg), diphenhydramine, and acetaminophen, prior to beginning OKT3 as therapy for acute rejection. Patients were observed, and symptoms scored semiquantitatively. Despite the presence of therapeutic PTF levels (721 +/- 726 ng/ml), the frequency and severity of side effects (fever, chills, headache, neurocortical symptoms, dyspnea, nausea, vomiting, diarrhea) did not differ between treatment groups. Likewise PTF did not affect renal function or immunologic response to OKT3, with similar graft and patient survival in both groups. Plasma levels of TNF alpha, IFN gamma, IL-6, and IL-8 increased as predicted following OKT3 administration, without significant differences between PTF and placebo groups. In this controlled, multicenter trial, pretreatment with oral PTF was ineffective in attenuating OKT3-related CRS in renal allograft recipients.

rHuTNF was locally applied to 26 patients with diverse advanced tumours and malignant pleural effusions following maximum possible drainage of their pleural cavities. 46 instillations (an average of 1.8 per patient) with doses between 0.10 mg and 0.50 mg were carried out. The total doses ranged from 0.15 mg to 1.01 mg per patient. 41% of the instillations resulted in flu-like symptoms, 35% fever/chill, 24% fatigue/malaise, 11% nausea/vomiting and 11% chest pain. All toxicities were fully reversible and could be treated successfully. There was no apparent relation between dose and side-effects. Of those patients treated primarily with TNF, 87% did not suffer from any recurrent effusion within 4 weeks after treatment. In patients who had already been treated employing other methods, this figure was 86%. Complete drainage of the pleural cavity was not absolutely necessary before application of TNF. Intrapleural instillation of TNF appears to be an effective method for achieving pleurodesis with relatively few side-effects and can be successful even after other methods have failed. It is a method which can also be applied to patients who have a poor general state of health.

The case fatality of WHO-defined 'severe falciparum malaria' remains unacceptably high, at 10-20%. However, a gradual decline in case fatality in adults and children treated in hospitals may reflect use of improved regimens of antimalarial chemotherapy and increased awareness of important complications of the disease. The development of severe, perhaps inevitably-fatal, malaria might be prevented by early appropriate chemotherapy of uncomplicated disease. At the most peripheral levels of the health service, suppository formulations of artemisinin derivatives can be administered even to patients who are vomiting or prostrated. At dispensaries, clinics or hospitals, where intramuscular or intravenous administration of antimalarial drugs is possible, quinine and artemisinin derivatives are the treatments of choice. There is growing evidence of the safety and efficacy of the quinine loading dose and of the use of artemether and artesunate, based on large, randomised, controlled clinical studies. No safe and effective form of prophylactic ancillary treatment has yet emerged. Results of studies of antipyretics, anticonvulsants (phenobarbitone), anticytokine/anti-inflammatory agents (anti-TNF antibodies, pentoxifylline, dexamethasone), iron chelators and hyperimmune sera have been disappointing. Only blood transfusion and treatment of respiratory, circulatory and renal failure are of obvious benefit. New ideas are needed, based on what is known of the pathophysiology of severe disease.
