Twenty-four patients with advanced cancer not reacting to conventional therapy were treated with 97 courses of i.v. MER (methanol extraction residue of BCG). MER was administered by i.v. infusion over a 4-h period, twice a week, in dosages varying from 0.05 mg to 1.25 mg. The skin reactivity to 5 recall antigens was evaluated in the patients. All patients except 4 were anergic. Twelve patients had no side-effects. Anergic patients had less side-effects than ergic patients. The side-effects recorded in the others were fever, chills, vomiting and tachycardia. The reaction subsided within 24 h after treatment and was tolerable for most patients. In 2 patients an objective improvement was observed. No changes in cutaneous reactivity, renal and hepatic functions were found. A significant increase in peripheral leucocyte count was noted in two patients and slight a increase in the remainder.

Effects of a single intravenous dose of highly purified staphylococcal enterotoxin A (SEA; 0.5 mg/kg) were studied in conscious rhesus monkeys. The mean survival time for four of five experimental monkeys was 8.7 h. Vomiting, pallor, abdominal distension, occasional diarrhea and dehydration were observed. Tachycardia and sustained hypotension developed prior to death. During vomiting, transient hypertension was induced.

A boy born healthy, developed gastrointestinal symptoms (diarrhea, vomiting, ulcerative stomatitis) and megaloblastic anaemia with thrombocytopenia and neutropenia at the age of five weeks. Serum levels of folate and cobalamin were normal, but there was cobalamin-mal absorption. In his serum apo-TC2 was not detectable and immunoreactive total TC2 was very low (10% of normal values). Cultured skin fibroblasts failed to secrete functioning TC2. Pharmacological amounts of parenteral Cyanocobalamin, administered regularly, led to hematological remission and normal development. Interruption of therapy was followed by relapse within a few weeks. A coexisting hypogammaglobulinemia did not respond to cobalamin therapy at the selected dose level. A family investigation of serum TC2 concentrations and the genetic TC2 variants in 7 persons of three generations yielded evidence of autosomal-recessive inheritance of a silent TC2 allele (TC2 QLFL SEA-like). Three persons with heterozygous deficiency were asymptomatic.

2B1 is a bispecific murine monoclonal antibody (BsMAb) with specificity for the c-erbB-2 and Fc gamma RIII extracellular domains. This BsMAb promotes the targeted lysis of malignant cells overexpressing the c-erbB-2 gene product of the HER2/neu proto-oncogene by human natural killer cells and mononuclear phagocytes expressing the Fc gamma RIII A isoform. In a Phase I clinical trial of 2B1, 15 patients with c-erbB-2-overexpressing tumors were treated with 1 h i.v. infusions of 2B1 on days 1, 4, 5, 6, 7, and 8 of a single course of treatment. Three patients were treated with daily doses of 1.0 mg/m2, while six patients each were treated with 2.5 mg/m2 and 5.0 mg/m2, respectively. The principal non-dose-limiting transient toxicities were fevers, rigors, nausea, vomiting, and leukopenia. Thrombocytopenia was dose limiting at the 5.0 mg/m2 dose level in two patients who had received extensive prior myelosuppressive chemotherapy. Murine antibody was detectable in serum following 2B1 administration, and its bispecific binding properties were retained. The pharmacokinetics of this murine antibody were variable and best described by nonlinear kinetics with an average t 1/2 of 20 h. Murine antibody bound extensively to all neutrophils and to a proportion of monocytes and lymphocytes. The initial 2B1 treatment induced more than 100-fold increases in circulating levels of tumor necrosis factor-alpha, interleukin 6, and interleukin 8 and lesser rises in granulocyte-monocyte colony-stimulating factor and IFN-gamma. Brisk human anti-mouse antibody responses were induced in 14 of 15 patients. Several minor clinical responses were observed, with reductions in the thickness of chest wall disease in one patient with disseminated breast cancer. Resolution of pleural effusions and ascites, respectively, were noted in two patients with metastatic colon cancer, and one of two liver metastases resolved in a patient with metastatic colon cancer. Treatment with 2B1 BsMAb has potent immunological consequences. The maximum tolerated dose and Phase II daily dose for patients with extensive prior myelosuppressive chemotherapy was 2.5 mg/m2. Continued dose escalation is required to identify the maximally tolerated dose for patients who have been less heavily pretreated.

This study examined the emetic activity of several staphylococcal enterotoxin type A and B (SEA and SEB, respectively) mutants that had either one or two amino acid residue substitutions. New sea gene mutations were constructed by site-directed mutagenesis; gene products were obtained with glycine residues at position 25, 47, 48, 81, 85, or 86 of mature SEA. Culture supernatants from Staphylococcus aureus RN4220, or derivatives containing either sea or a sea mutation, were analyzed for the ability to stimulate proliferation of murine splenocytes, as determined by incorporation of [3H]thymidine. Culture supernatants containing SEA-N25G (a SEA mutant with a substitution of glycine for the asparagine residue at position 25), SEA-F47G, or SEA-L48G did not stimulate T-cell proliferation, unlike supernatants containing the other substitution mutants. Purified preparations of SEA-N25G had weak activity and those of SEA-F47G and SEA-L48G had essentially no activity in the T-cell proliferation assay. All mutants except SEA-V85G, which was degraded by monkey stomach lavage fluid in vitro, were tested for emetic activity. SEA-C106A and two SEB mutants, SEB-D9N/N23D and SEB-F44S (previously referred to as BR-257 and BR-358, respectively), whose construction and altered immunological properties have been reported previously, were also tested in the emetic assay. Each mutant was initially administered intragastrically at doses of 75 to 100 micrograms per animal; if none of the animals responded, the dose was increased four-to fivefold. SEA-F47G, SEA-C106A, and SEB-D9N/N23D were the only mutants that did not induce vomiting at either dose tested; these three mutants had reduced immunological activity. However, there was not a perfect correlation between immunological and emetic activities; SEA-L48G and SEB-F44S retained emetic activity, although they had essentially no T-cell-stimulatory activity. These studies suggest that these two activities can be dissociated.

Metoclopramide, a drug used for the relief of nausea and emesis, is currently under development as a radio- and chemosensitizing agent. Its usefulness in high doses, however, is limited by its central nervous system side effects. Neu-metoclopramide (Neu-Sensamide), a novel, concentrated, phosphate-buffered, pH-adjusted (pH = 6.5-7.0) formulation of metoclopramide, has been shown to have an improved side-effect profile in animal studies. The present double-blind, four-way crossover study compared the central nervous system effects and pharmacokinetics of neu-metoclopramide (intravenously and intramuscularly at 1.8 mg/kg) with intravenous metoclopramide and intramuscular placebo in 19 healthy male volunteers. Eight participants withdrew from the study, one because of noncompliance and seven because of adverse events. A total of 28 central nervous system events were observed with intravenous metoclopramide administration, whereas 16, 15, and 6 such events were attributed to intravenous neu-metoclopramide, intramuscular neu-metoclopramide, and placebo, respectively. Extra-pyramidal effects occurred on 10 occasions: 7 after intravenous metoclopramide, 2 after intravenous neu-metoclopramide, and 1 after intramuscular neu-metoclopramide. No significant differences were observed in the pharmacokinetic profiles of the three formulations of metoclopramide. It may be speculated, therefore, that the molecular conformational changes inherent to neu-metoclopramide result in a reduced side-effect profile compared with conventional metoclopramide formulations.

This study determines the ovarian effects, contraceptive efficacy, and effects on serum levels of norethindrone acetate (NET-Ac) and ethinyl estradiol (EE) among women using a single contraceptive vaginal ring (CVR) cyclically over a period of 1 year. A total of 60 women were enrolled and used the ring according to a schedule of 3 weeks "in" and 1 week "out." Assays of serum norethindrone acetate (NET-Ac) ethinyl estradiol (EE) levels were taken twice weekly in cycles 6, 9, and 13. Despite luteal activity in some cycles, no pregnancies were noted within the 12-month study period. Heavier body weight was associated with increased probability of luteal activity. Mean serum levels decreased over the last 3 months of CVR use, accounting for the increase in luteal activity and possible ovulations in cycle 13. Among women in Sydney, by contrast with women in the other centers, a difference in the effect on lipids was seen. However, the changes in lipid levels were very small. The side effects were a little different from those experienced by women using a combined pill. Nausea and vomiting were largely confined to early cycles and most common in the first days of the first cycle. Weight gain was also not a problem, although there was a small mean increase in body weight over the 12-month treatment period. This study indicates that use of a single CVR releasing EE and NET-Ac over a period of 12 months constitutes an acceptable, safe and effective contraceptive method.

HELLP syndrome belongs to the group of pathological states known as pregnancy-induced hypertension or EPH gestosis. The basic criteria for establishing the diagnosis are as follows: H for hemolysis, EL for elevated liver enzymes and LP for low platelets. A pregnant woman, 38 years of age, multipara (V pregnancy, third delivery) has been admitted to the Clinic of Gynecology and Obstetrics in Novi Sad in 36-37 week gestation complaining of nausea, vomiting, epigastric pain, general weakness, exhaustion as well as symptom of previously diagnosed preeclampsia. Due to signs of fetal distress, the patient has undergone urgent cesarean section, giving birth to a female premature newborn infant. Twenty-four hours after delivery all symptoms and signs HELLP syndrome manifested. Being in a critical state, the patient has been transferred to the Institute of Surgery, Clinic of Anesthesiology and Intensive Care with signs of multiple organ failure. With this case report of a patient with HELLP syndrome, we wished to point to importance of continual intensive clinical follow-up, laboratory monitoring and corresponding therapeutic procedures, and at the same time to this relatively rare syndrome.

We report a female newborn with Ondine's curse and Hirschsprung's disease--neurocristopathic syndrome. The female infant required endotracheal intubation and mechanical ventilation due to apnea which developed soon after birth. She had abdominal distension with bilious vomiting. A barium enema revealed a caliber change at the rectum and rectal biopsies showed no ganglion cells. Colostomy was performed at the age of 17 days. Hypoxemia with hypercapnia was noted during her sleep, and tracheostomy was performed at the age of 55 days. In addition, deafness and pupillary autonomic dysfunction were observed. The definitive surgery for Hirschsprung's disease was performed at the age of 4 months. She is now 2 years old with normal growth but needs ventilator support at home. In this case, we detected no mutation in the RET gene and EDNRB gene.

An outbreak of staphylococcal food poisoning due to an egg yolk (EY) reaction-negative strain occurred in Japan. Twenty-one of 53 dam construction workers who ate boxed lunches prepared at their company cafeteria became ill, and eight required hospital treatment. The outbreak showed a typical incubation time (1.5-4 h with a median time of 2.7 h) and symptoms (vomiting and diarrhea) of staphylococcal food poisoning. Staphylococcus aureus, which produces staphylococcal enterotoxin (SE) A, was isolated from four fecal specimens of eight patients tested. Scrambled egg in the boxed lunches contained 20-40 ng/g of SEA, and 3.0 x 10(9)/g of viable S. aureus cells that produced this toxin. All isolates from patients and the food were EY reaction-negative, coagulase type II, and showed the same restriction fragment length polymorphism (RFLP) pattern. We concluded that the outbreak was caused by scrambled egg contaminated with EY reaction-negative S. aureus. In Japan, outbreaks of staphylococcal food poisoning are mainly caused by EY reaction-positive S. aureus, and EY reaction-negative colonies grown on agar plates containing EY are usually not analyzed further for detection of S. aureus. The present outbreak suggested that EY reaction-negative isolates should be subjected to further analysis to detect the causative agents of staphylococcal food poisoning.
