Amelioration of cisplatin (CDDP)-induced vomiting and anorexia by methylprednisolone (MP) was studied using conscious dogs. The incidence of vomiting was 88.9% and the mean number of emetic episodes was 8.22 +/- 1.25/dog during 5 hours after i.v. administration of 1.5 mg/kg CDDP in 9 dogs. In control dogs, food intake on the day after administration of CDDP was markedly reduced to 60 +/- 22.4 g/day from 461 +/- 23 g. Continuous high-dose infusion of MP (10 mg/kg, 10 min before the start of CDDP infusion and 50 mg/kg/h for 5 h) markedly reduced the incidence (33%) and mean number of vomiting episodes (2.00 +/- 1.51/dog) and also mitigated the reduction of food intake (350 +/- 30.6 g/day). However, continuous low-dose infusion of MP (5 mg/kg, 10 min before CDDP infusion and 16.6 mg/kg/h for 5 h) showed a little effect on CDDP-induced vomiting. Plasma MP levels after the high-dose and the low-dose regimens were 6.20 +/- 0.628 micrograms/ml and 4.66 +/- 1.72 micrograms/ml, respectively, 30 min after CDDP infusion. In both cases, MP levels gradually increased and reached to those more than twice 5 hours after CDDP infusion. Bolus administrations of MP (30 mg/kg, each time) 2 hr and 30 min before CDDP infusion also significantly reduced the mean number of emetic episodes (3.22 +/- 1.33/dog) and mitigated the reduction of food intake (325 +/- 37.3 g/day). No significant changes in catecholamines, prostaglandins, vasopressin, plasma renin activity, Na+, K+, Mg++ and osmolality in peripheral blood were noted after administration of CDDP and/or MP. The results suggest that administration of MP was effective against CDDP-induced vomiting and anorexia in dogs.

The authors describe a case of hypodipsia and severe hypernatremia most probably secondary to hydrocephalus in a 22-year-old man in the absence of abnormalities of ADH secretion or metabolism. The patient became hypernatremic only in situations when the decreased spontaneous fluid intake was insufficient to replace that lost caused by sweating or vomiting. Adequate hydration returned the sodium value to normal.

The Staphylococcus aureus enterotoxins represent a group of proteins that cause emesis and diarrhea in humans and other primates. We have developed a rapid two-step high-pressure liquid chromatography (HPLC) procedure for purification of staphylococcal enterotoxin B (SEB). Sterile filtrates (2.5 liters) of strain 10-275 were adsorbed directly onto a reversed-phase column (50 mm by 30 cm Delta Pak; 300 A [30 nm], 15 microns, C18). SEB was obtained by using a unique sequential gradient system. First, an aqueous ammonium acetate to acetonitrile gradient followed by an aqueous trifluoroacetic acid (TFA) wash was used to remove contaminants. A subsequent TFA to acetonitrile-TFA gradient eluted the bound SEB. Further purification was obtained by rechromatography on a cation-exchange column. From 35 to 45% of the SEB in starting filtrates was recovered. Analysis by immunoblotting of samples separated on sodium dodecyl sulfate-polyacrylamide gels indicated that HPLC-purified SEB exhibited immunological and biochemical properties similar to those of the SEB standard. Induction of an emetic response in rhesus monkeys showed that the HPLC-purified toxin also retained biological activity.

Cardinal signs of red mold toxicosis in man and farm animals are vomiting, nausea, diarrhea, and food refusal. The red mold toxicosis has been suggested to be induced by trichothecenes, which are produced by Fusarium fungi. Fusarenon-X (F-X) is one of the trichothecene mycotoxins. The ip injection of F-X to rats causes an expansion of the small intestine and watery diarrhea. In this study, we measured the concentrations of protein, sodium, potassium, and calcium in the serum of rat treated with F-X for the sake of demonstrating the loss of serum protein and the decreases of serum sodium and calcium by F-X. Since it is well known that some diarrheal diseases are due to the increase of cyclic nucleotide level in the intestinal mucosa, we also measured cyclic AMP and cyclic GMP levels in the intestinal mucosa. It was demonstrated that F-X did not increase the cyclic AMP and cyclic GMP levels in the jejunal and the ileal mucosa at 8 and 24 hr after F-X treatment. The results obtained in this work suggest that F-X-induced diarrhea is not mediated by the cyclic nucleotide system.

Cis-diamminedichloroplatinum II (CDDP; 52-169 mg/m2) mixed with angiotensin II (1.5-10 micrograms/min) was infused into the hepatic artery in 33 patients with hepatocellular carcinoma. Simultaneously, sodium thiosulfate (10-50 g) was administered intravenously in order to reduce the systemic toxicity of CDDP. Over 50 per cent reduction in tumor size was obtained in 18 patients (55%). Complete response was achieved in 4 patients (12%). Serum alpha-fetoprotein (AFP) levels decreased by more than 75 per cent in 10 of 18 patients in whom the previous AFP level was more than 200 ng/ml. The one year survival rate was estimated at 61 per cent by the Kaplan-Meier method. Alimentary symptoms (nausea, vomiting) were mild or non-existent in nearly 90 per cent of treatments. Peptic ulcer and abdominal pain were manifested in small numbers. Severe changes in the laboratory data were not observed. High dosage arterial infusion of CDDP and angiotensin II and intravenous injection of sodium thiosulfate was well tolerated and gave effective therapy in hepatocellular carcinoma.

Seventeen patients with primary or metastatic malignancy in the liver were treated with 'two-route chemotherapy' (TRC). One course of this TRC consisted of hepatic artery infusion of cisplatin, 120 mg/m2, in combination with concurrent intravenous administration of sodium thiosulfate, its neutralizing agent, at a dose of 9.0 g/m2 by a rapid push, followed by 1.2 g/m2/h by continuous infusion for 6 h. Five of 11 (45%) hepatocellular carcinoma and two of six (33%) metastatic tumors achieved partial response. Although almost all patients experienced nausea or vomiting, severe side-effects, including nephrotoxicity, peripheral neuropathy or ototoxicity, were not encountered. Myelosuppression was observed in one patient after seven courses of this TRC. The results indicate that TRC may be relatively effective against hepatic malignancies in patients without severe toxicity.

Apart from the classic distal renal tubular acidosis (RTA), the proximal RTA, and a few cases of distal RTA and renal bicarbonate wasting we know only 2 cases of infantile transient distal RTA with bicarbonate wasting. A 3 month-old male patient is admitted because of deficient suction, vomiting and dehydration. Despite a strong metabolic acidosis (pH 7,09, bicarbonate 8,6 mMol/l, chloride 110 meq/l) the urine is constantly alkaline; clinically the disease manifests itself in the form of an alkali-resistant RTA. Accompanying troubles such as inner ear deafness, G6PDH deficiency, hyperparathyroidism and vitamin D intoxication are to be excluded. A bicarbonate study carried out with care so as to prevent extracellular fluid expansion reveals the lack of excretion of titratable acid (-2.4 to +4.7 mueq/min/1.73 m2), an reduced excretion of ammonium (5 to 24.8 mueq/min/1.73 m2) with regard to GFR (42.4 ml/min/1.73 m2), and a constant loss of bicarbonate (FE HCO3- about 10%) covering most of the bicarbonate plasma concentration, which results in a constantly negative net acid excretion. Even with alkalosis there is no urine minus blood pCO2 increase. The renal excretion of gamma GT is significantly reduced. On substitution with high quantities of bicarbonate (10 meq/kg BW/day) the defect heals up at the age of 13 months. The pathogenesis of this disease is not quite clear, but is similar to that of the Lightwood infantile RTA. The acidification defect may be explained by a deficient hydrogen ions--secretion in the distal tubule; as for kinetics, it is not in the proximal tubule that the bicarbonate wasting occurs but it may be due to increased sodium delivery to the distal nephron.

Forty-one children, aged 1 to 5 years, who accidentally ingested levothyroxine sodium were studied. Symptoms possibly associated with the ingestion occurred in 11 patients (27%). These symptoms (tachycardia, hyperactive behavior, fever, vomiting, diarrhea, diaphoresis, and flushing) were categorized as minor and all resolved without treatment. Because observed effects were generally mild and often unrelated to either estimated amounts of hormone consumed or serum thyroxine levels, a conservative approach to patient treatment is recommended in cases of levothyroxine ingestion in children.

We have identified ten children who developed gastritis after prolonged anticonvulsant therapy that included either valproic acid or divalproex sodium. Presenting symptoms were primarily feeding difficulties, including anorexia and refusal to eat. Vomiting was present in two thirds of the patients, with diarrhea, weight loss, and abdominal pain occurring less frequently. Occult blood in stool samples was a late development. All patients responded to therapy with H2-receptor antagonists, oral antacids, or both, with prolonged treatment often necessary to prevent relapse. Although gastrointestinal tract side effects are common with the initiation of valproate sodium therapy, feeding difficulties after long-term treatment are less common. Gastritis should be suspected in children receiving valproate therapy when feeding difficulties arise, particularly if the symptoms are persistent or recurrent.

Apomorphine, a centrally-acting emetic, was administered subcutaneously (50 micrograms/kg) to nine normal subjects (four male, five female; aged 22-36 years) and four patients with idiopathic diabetes insipidus (DI) (one male, three female; aged 24-49 years). In the normal subjects this stimulus caused nausea (and vomiting in seven of nine) with a latency of 9.5 +/- 0.9 min which was followed by a large increase in plasma arginine vasopressin (AVP) concentration (from 0.9 +/- 0.2 pmol/l to 249 +/- 104 pmol/l at 15 min after the onset of symptoms; mean +/- SEM, P less than 0.01). There was a small but significant increase in plasma oxytocin (OXT) concentration (from 1.6 +/- 0.4 pmol/l to 6.2 +/- 3.4 pmol/l; P less than 0.05). Mean arterial pressure (MAP) fell slightly (from 87 +/- 1.9 mm Hg to 71 +/- 4.4 mm Hg; P less than 0.05) 15 min after the onset of nausea; there was no change in blood haematocrit or plasma osmolality and sodium concentration. In the DI patients apomorphine produced nausea (with vomiting in three of four) with a latency of 10.0 +/- 1.4 min but failed to cause an increase in either plasma AVP or OXT. In the DI patients the fall in MAP did not reach statistical significance (83 +/- 4 mm Hg to 71 +/- 11 mm Hg); there was also no change in haematocrit, osmolality or sodium concentration. Ipecacuanha, an emetic with both peripheral and central actions, was administered orally to seven normal subjects (three male, four female; aged 22-36 years) six of whom also underwent apomorphine tests.(ABSTRACT TRUNCATED AT 250 WORDS)
