Twenty-one patients with liver metastasis of gastrinoma received intravenous streptozotocin (STZ: 500 mg/sqm.day) and 5 fluorouracil (5 FU: 400 mg/sqm.day) during 5 consecutive days every 6 weeks. Variations in tumor mass (TM) on CT scan and in serum gastrin levels were assessed every two courses. Treatment was continued if TM decreased or remained unchanged, and if severe renal toxicity of STZ was not observed. Three patients had a minor (25-50 percent decrease in TM) and transient response. Only one patient (5 percent) presented an objective response (greater than 50 percent) which lasted 55 months. TM remained unchanged in 28 percent and increased in 65 percent of cases. Changes in serum gastrin levels did not parallel those of TM. Nausea and/or vomiting (66 percent) was easily controlled by symptomatic treatment. Renal toxicity (24 percent), including one case of acute and transient renal failure due to accidental overdosing, was observed in 24 percent of cases. This prospective study does not confirm the efficacy of combined STZ-5 FU as previously suggested by retrospective data.

Morphine-6-glucuronide is an active metabolite of morphine that has analgesic properties and is measurable in the plasma and cerebrospinal fluid of patients treated with this opioid. Decreased clearance of the compound has been observed in patients with renal insufficiency, and this has been associated with an increase in the ratio of morphine-6-glucuronide to morphine. Clinical effects from accumulation of morphine-6-glucuronide have not been described with the exception of case reports in which patients with renal failure were noted to develop opioid toxicity with high plasma levels of the metabolite and low levels of the parent drug. We describe a patient who experienced chronic nausea and an episode of confusion while treated with a small, stable dose of oral morphine in the setting of mild renal insufficiency. Relatively high levels of morphine-6-glucuronide were measured and all symptoms resolved promptly as the concentration of this metabolite declined. This case provides suggestive evidence that morphine-6-glucuronide can produce clinically significant effects in patients with mild renal insufficiency.

Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.

A clinical trial, to evaluate the effects of a Chinese herbal drug, Rheum E and angiotensin converting enzyme inhibitor, Captopril on chronic renal failure (CRF), was conducted. Thirty cases with initial serum creatinine (Scr) levels of 344.8 +/- 114.0 mumol/L were allocated randomly to 3 groups: Rheum E treated group, Captopril treated group and Rheum E + Captopril group. A control group of 12 cases were on dietary therapy alone. During the 6-22 months of treatment, all the patients were kept on low-protein (0.6g/kg/d), and low-phosphorus (10mg/kg/d) diet. The results showed that the progression rate of renal failure, calculated by regression analysis of 1/Scr vs time, was found to be retarded after treatment with the increased regression coefficient (b value). Scr levels and blood urea nitrogen were kept stable or fell slightly. Albumin rose during the follow-up period (P less than 0.05) in the treated patients, being more marked in both Rheum E and Rheum E + Captopril groups. Uremic symptoms of nausea, anorexia improved in most of the treated patients. It is concluded that long-term low-dose Rheum E taken orally is beneficial to CRF. Its effect is better than that of Captopril. The regime of Rheum E and Captopril is a preferable choice in the long-term treatment for preventing progression of CRF.

Nonsalicylate, nonsteroidal anti-inflammatory drugs (NSAIDs) can be divided into 4 chemical classes: acetic acids, fenamic acids, oxicams and propionic acids. Most NSAID overdoses result in a benign outcome. Of 50,614 exposures reported to poison centres in the United States in a 2-year period, 131 (0.26%) had a major outcome, with 10 deaths. Despite the generally mild effects reported in large patient series, isolated case reports have documented serious toxicity, such as seizures, hypotension, apnoea, coma and renal failure. The majority of these consequences occur after ingestion of substantial quantities by adults attempting suicide. Rarely, with ibuprofen and piroxicam, children who ingest small amounts in accidental exposure develop serious toxicity. Typical signs and symptoms of NSAID overdose include nausea, vomiting, headache, drowsiness, blurred vision and dizziness. Seizures are rarely documented across all NSAID classes, with the exception of mefenamic acid (where seizures occur in over one-third of cases), or following massive ingestion of other agents. Drugs in the propionic acid group have produced metabolic acidosis, respiratory depression and coma in severe cases. Ibuprofen is the agent with the most published data on overdose, probably because it is available without a prescription in many countries. Symptoms are unlikely after ingestion of 100 mg/kg or less, and are usually not life-threatening unless more than 400 mg/kg is ingested. There is some relationship between plasma concentrations and the potential for development of symptoms, but plasma concentrations have no impact on treatment decisions. Treatment of NSAID overdose is entirely supportive. Recent trends in emergency department procedures regarding gastric decontamination are evolving towards the recommended administration of activated charcoal without gastric emptying in patients presenting more than 1 hour after ingestion, although gastric lavage, followed by administration of activated charcoal, may be advisable in patients who present earlier. Home administration of syrup of ipecac is still recommended if treatment is given shortly after ingestion, with a few exceptions: for example, ipecac is contraindicated after ingestion of mefenamic acid or ibuprofen in amounts greater than 400 mg/kg. Urine alkalinisation and diuresis have been recommended to enhance the elimination of NSAIDs, based on a pKa in the range of 3 to 5. However, because the drugs are universally highly protein bound, with little unchanged renal excretion, this technique is not likely to be beneficial. Haemodialysis is also unlikely to enhance elimination, but may be required if oliguric renal failure develops. Multiple dose activated charcoal may be useful in enhancing elimination of NSAIDs with long half-lives, such as piroxicam and sulindac.

Although the postpericardiotomy syndrome is a common complication of cardiac operations, the most effective drug regimen for the treatment of this condition has not been established. The present study was designed to evaluate the effectiveness of nonsteroidal antiinflammatory drugs (NSAIDs) in the treatment of postpericardiotomy syndrome, in a double-blind, placebo-controlled randomized trial with a 10-day course of ibuprofen or indomethacin. Of 1019 adult patients undergoing cardiac operations during a 14-month period, a diagnosis of postpericardiotomy syndrome was made in 187, and 149 were enrolled in the study. Diagnosis was based on the presence of at least two of the following: fever, anterior chest pain, and friction rub. Drug efficacy was defined as the resolution of at least two of these criteria within 48 hours of drug initiation. Ibuprofen and indomethacin were 90.2% and 88.7% effective, respectively, and both were significantly more effective than placebo (62.5%, p = 0.003). The occurrence of side effects, including nausea, vomiting, renal failure, and fluid retention, was low in all groups (13.1% for ibuprofen, 16.1% for indomethacin, and 16.7% for placebo [p = not significant). Length of hospital stay, incidence of ischemic events, and accumulation of significant pericardial effusions were similar in all groups. The results of this study demonstrate that both ibuprofen and indomethacin provide safe and effective symptomatic treatment for postpericardiotomy syndrome.

We prospectively evaluated infusion-related toxicities in 82 recipients of autologous bone marrow grafts. The grafts were cryopreserved in 10% dimethylsulfoxide and stored in liquid nitrogen. All grafts were concentrated and buffy-coat cells were collected. Forty-seven grafts were treated ex vivo with 4-hydroperoxycyclophosphamide (4-HC) at 100 micrograms/mL; 26 grafts were further processed using density-gradient separation and treated with 4-HC at 60 micrograms/mL. Nine buffy-coat concentrates were frozen without drug treatment. Before infusion, patients were medicated with mannitol, hydrocortisone, and diphenhydramine. Grafts were rapidly thawed and immediately infused without further manipulation. During the infusions, 33 (70%) recipients of treated buffy-coat, 5 (56%) recipients of untreated buffy-coat, and 6 (23%) recipients of density-gradient separated grafts experienced varying symptoms including nausea, abdominal cramping, and flushing. Forced vital capacities for 83% of the recipients of treated buffy-coat concentrates decreased after the graft infusion; six of these patients complained of dyspnea and one patient experienced an acute episode of respiratory decompensation. Decreased heart rates were observed in 98% of the recipients of treated buffy-coat cells with asymptomatic bradycardia occurring in 45%. Forty-five patients (96%) in this group experienced transient hypertension, with 18 (38%) requiring additional medications within 6 hours after the infusion for control of blood pressure. Similar cardiovascular changes were observed in the recipients of untreated buffy-coat concentrates. One recipient of an untreated buffy-coat concentrate had 2 degrees heart block after the graft infusion. Twenty-three (88%) recipients of density-gradient separated grafts had decreased heart rates and 21 (81%) had increased blood pressure. However, the degrees of change were less than those experienced by the recipients of treated buffy-coat cells (P less than .01). Forced vital capacities were not affected by the infusion of the density-gradient separated grafts. No renal failure or obvious hemolytic episodes occurred for any patient group. Minor to moderate toxicities were associated with cryopreserved graft infusions. Recipients of buffy-coat separated grafts, both treated and untreated, experienced more complications than the recipients of density-gradient separated grafts. These toxicities may relate to the volumes of cryoprotectant and cell lysis products infused, which were less for the more highly purified density-gradient separated grafts.

The authors report a case of toxic hepatitis in a woman of 22 years of age in the third trimester of her first pregnancy treated by methyldopa for hypertension of pregnancy which was diagnosed at 33 weeks of amenorrhoea. The prodromal symptoms were mild and consisted of nausea, vomiting and rise in temperature and this phase was associated with febrile jaundice without pruritus and it was only associated with coagulation disorders in the third stage of labour. This was a case of mixed cytolytic hepatitis (ASAT x 3N) and cholestasis (x 1.5N). The outcome was fatal. The patient died three days after delivery following haematemesis and renal failure as well as hepatic encephalopathy. The main diagnostic feature was acute hepatic stasis in spite of the absence of pruritus and the presence of a raised temperature after hematolytic, viral and obstructive causes had been eliminated. Histology confirmed that there was toxic hepatitis. This aetiology was suggested by the timing of the symptoms after MD (methyldopa) had been taken. Elkington described methyldopa hepato-toxicity in 1969. Fatal cases in the literature were in patients who were over 40 years of age. Methyldopa is used in pregnant women because of its safety as far as the fetus is concerned. Mechanism by which it causes toxic hepatitis is a combination of abnormal metabolism (the cytochrome P450 chain produces an antigen) and an immune reaction in response to this antigen and these explain why such severe and potentially fatal forms of the condition exist.(ABSTRACT TRUNCATED AT 250 WORDS)

In the course of two and a half years we treated six diabetic women on account of lactate acidosis during concurrent biguanide administration. The patients were given an average dose of 290 mg Buformin/24 hours. Their mean age was 71 years. Three patients died, i.e. the mortality was 50%. All patients reported nausea, vomiting and abdominal pain. Two suffered from diarrhoea. Two patients suffered from renal failure and one from cardiac weakness. One patient was in coma. The mean lactate concentration was 14.7 mmol/l, pH on admission was 6.84. The patients were given on average 550 mmol bicarbonate. In two instances bicarbonate dialysis was used. The authors discuss the pathophysiology, clinical aspects and importance for treatment and prevention of lactate acidosis during biguanide treatment.

24 days after starting treatment of psoriasis with fumaric acid derivatives (0.8-1.0 g orally, plus unknown quantities locally) a 21-year-old woman developed acute oliguric renal failure with a rise of serum creatinine levels to 1094 mumol/l (12.4 mg/dl). Deterioration of renal function had been preceded by severe abdominal symptoms with nausea, vomiting and colicky pain. On admission to hospital she was dehydrated with hyponatraemia and hypokalaemia. There was glomerular microhaematuria, increased excretion of renal epithelia, and tubular proteinuria. Renal biopsy demonstrated acute tubular damage with vacuolization of proximal epithelia, dilated tubules and scattered necroses. After intermittent haemodialysis (13 courses over two weeks) renal function gradually recovered, as demonstrated at a follow-up examination four months after discharge.
