Carbamazepine (CBZ) can produce serious side-effects such as hepatitis, LES, agranulocytosis, aplastic anaemia and skin eruptions. The latter, of polymorphous appearance (morbilliform, orticorioid and vesicular) depend on the levels of CBZ and retreat rapidly with the administration of prednisone. 2 cases of rash following introduction of the drug quickly resolved with its suspension are reported.

New information on the tolerability of lovastatin has emerged from an ongoing study of long-term therapy; preliminary results from a large, 48-week clinical trial; and spontaneous reports of adverse events observed during prescription use of the drug in the United States. As of June 1989, 744 patients had received lovastatin for an average duration of 3.6 years in the long-term study. Drug-attributable adverse events necessitated withdrawal of 17 patients (2.3%) from the study. These adverse effects were asymptomatic elevations of transaminases (10), skin rash (3), gastrointestinal symptoms (2), myopathy (1) and insomnia (1). No effect of lovastatin on the human lens was observed. In the 48-week study, 8,245 patients were randomized into 5 equal groups to receive placebo or lovastatin 20 or 40 mg once or twice daily on a double-blind basis. Only 3 cases of myopathy were observed, all in patients taking lovastatin 40 mg twice daily. The incidence of withdrawal from the study because of raised transaminases was approximately 0.1% in the placebo group vs 0.1, 0.7, 0.6 and 1.5% in patients taking lovastatin in doses of 20 mg once daily, 40 mg once daily, 20 mg twice daily and 40 mg twice daily, respectively. Lovastatin has been available in the United States since September 1987. By June 1989, the drug had been prescribed for approximately 1 million patients. Drug-attributable adverse events not observed in clinical trials (such as hypersensitivity reactions and symptomatic hepatitis) have been reported, but the incidence of each appears to be extremely low.

A newly developed human immunoglobulin liquid preparation for intravenous injection was studied for efficacy, safety, and usefulness in treating severe and/or refractory infections in children receiving antibiotic treatment. It is suggested that C-425 is a useful intravenous preparation of human immunoglobulin for the treatment of severe and/or refractory infections in pediatrics. C-425 was administered to 87 inpatients with severe and/or refractory infections at 23 institutions nationwide. The Committee selected 61 cases for the present analysis. Physicians in charge judged clinical efficacy of C-425 to be "excellent" in 23 cases (40.4%), "good" in 24 (42.1%), "fair" in 7 (12.3%), "poor" in 3 (5.3%), and "unknown" in 4. The efficacy rate was calculated at 82.5% when the "excellent" and "good" cases were combined, and 94.7% when the "fair" cases were also included. According to the Committee's judgement, the efficacy of C-425 was "excellent" in 27 cases (44.3%), "good" in 18 (29.5%), "fair" in 7 (11.5%), and "poor" in 9 (14.8%). The efficacy rate was 73.8% when the "excellent" and "good" cases were combined. The rate increased to 85.2% when the "fair" cases were added. Organisms were identified in 31 cases, and the time course was followed in 19 instances. Organisms were eliminated in 12 cases (63.2%), decreased in number in 2 (10.5%), and persisted in 5 (26.3%). Eradication rate was 63.2%. One of the 87 patients died of fulminant hepatitis 2 days after the end of the treatment. The remaining 86 cases were analyzed for the safety of C-425. A skin rash was observed in one case. Laboratory examination revealed increase in transaminase levels in a total of 8 cases; both in GOT and GPT in 5, in GOT alone in 2, and in GPT alone in 1. These findings were not clinically important.

Fourteen patients with T-cell-derived leukemia and lymphoma underwent high-dose chemoradiotherapy and anti-T-cell monoclonal antibody-treated autologous bone marrow transplantation (ABMT). All patients were either in sensitive relapse or had adverse prognostic features, and five patients had a history of bone marrow involvement with disease. Patients received a median of 2 (1 to 3) prior chemotherapy regimens; 10 patients received local radiotherapy. After high-dose ablative therapy, greater than 500/mm3 granulocytes and greater than 20,000 untransfused platelets/mm3 were noted at a median of 23 (13 to 48) and 26 (15 to 43) days post-ABMT, respectively. Natural killer (NK) cells, T cells (predominantly T8+), and monocytes were noted within the first 1 to 2 months post-AMBT, as seen in other series. Disease-free survival was a median of 10.1 months, 5.9 months for patients with T acute lymphoblastic leukemia or lymphoblastic lymphoma and 25.6 months for patients with T non-Hodgkin's lymphoma (NHL). Toxicities were common and severe. Thirty-six percent of patients developed bacteremias early post-BMT. Late complications included a skin rash consistent with graft versus host disease; infections with Herpes zoster, hepatitis, and Pneumocystis carinii; and the development of Epstein-Barr virus associated lymphoproliferative syndrome. Our findings suggest that patients who have undergone T-depleted ABMT have a profound immunodeficiency not reflected in the phenotypic reconstitution of the T and NK cells. Characterization of the functional deficiency may facilitate the development of methods to reduce the long-term toxicity of AMBT in these patients.

We reported a case of disulfiram-induced hepatitis with unique clinical features and compared our case with others in the literature. Our patient had headache, mild fever, nausea, vomiting, rash, and eosinophilia after 3 weeks of disulfiram therapy. Subsequent liver biopsy showed low-grade lobular hepatitis. After disulfiram therapy was discontinued, symptoms subsided and results of liver function tests returned to normal.

Quinidine, procainamide and disopyramide are antiarrhythmic drugs in the class 1A category. These drugs have a low toxic to therapeutic ratio, and their use is associated with a number of serious adverse effects during long term therapy and life-threatening sequelae following acute overdose. Class 1A agents inhibit the fast inward sodium current and decrease the maximum rate of rise and amplitude of the cardiac action potential. Prolonged Q-T interval and, to a lesser extent, QRS duration may be observed at therapeutic concentrations of quinidine. With increasing plasma concentrations, progressive depression of automaticity and conduction velocity occur. 'Quinidine syncope' (a transient loss of consciousness due to paroxysmal ventricular tachycardia, frequently of the torsade de pointes type) occurs with therapeutic dosing, often in the first few days of therapy. Extracardiac adverse effects of quinidine include potentially intolerable gastrointestinal effects and hypersensitivity reactions such as fever, rash, blood dyscrasias and hepatitis. Procainamide produces electrophysiological changes that are similar to those of quinidine, although Q-T interval prolongation with the former is less pronounced at therapeutic concentrations. Hypersensitivity reactions including fever, rash and (more seriously) agranulocytosis are associated with procainamide, and a frequent adverse effect requiring cessation of therapy is the development of systemic lupus erythematosus. Of the 3 drugs, disopyramide has the most pronounced negative inotropic effects, which are especially significant in patients with pre-existing left ventricular dysfunction. As with quinidine, unexpected 'disopyramide syncope' at therapeutic concentrations has been described. Anticholinergic side effects are common with this drug and may require cessation of therapy. Disopyramide therapy may unpredictably induce severe hypoglycaemia. Severe intoxication with the class 1A agents may result from acute accidental or intentional overdose, or from accumulation of the drugs during long term therapy. Acute overdose can result in severe disturbances of cardiac conduction and hypotension, frequently accompanied by central nervous system toxicity. Decreased renal function can cause significant accumulation of procainamide and its active metabolite acecainide (N-acetyl-procainamide), resulting in severe intoxication. Mild to moderate renal dysfunction is less likely to lead to quinidine or disopyramide intoxication, unless renal failure is severe or concurrent hepatic dysfunction is present. Management of acute intoxication with class 1A drugs includes gut decontamination with provision of respiratory support and treatment of seizures as needed. Hypertonic sodium bicarbonate, by antagonising the inhibitory effect of quinidine on sodium conductance, may reverse many or all manifestations of cardiovascular toxicity.(ABSTRACT TRUNCATED AT 400 WORDS)

In a survey of patients admitted to the medical and surgical wards of Groote Schuur Hospital during the 5-year period 1983-1987 38 patients with severe drug-induced hepatitis were identified. Fifty-three per cent of these reactions were caused by anti-tuberculosis drugs, 21% to phenytoin and 11% to methyldopa. Whereas 82% of the patients were jaundiced, only one-third had gastro-intestinal symptoms and/or fever and only 24% had a rash. Twenty-six per cent of patients were encephalopathic on admission. The overall mortality rate was 24%. Forty per cent of patients with hepatitis caused by anti-tuberculosis therapy died. Many patients had continued to receive therapy despite signs of liver disease. These findings underline the need for a high index of suspicion in the diagnosis of drug-induced liver disease and for early withdrawal of the offending agent(s).

Long-term follow-up data on young patients receiving amiodarone is lacking, especially in relation to growth and late side effects. The records of 95 young patients (mean age 12.4 years; range 3 weeks to 31.5 years) who received amiodarone were reviewed. Minimal follow-up time for those continuing to take amiodarone was 1.5 years; the mean duration of therapy was 2.3 years (maximal 6.5). The mean maintenance dosage was 7.7 (1.5 to 25) mg/kg body weight per day. Initial success (based on symptoms and 24 h electrocardiogram) was achieved in 23 of 34 patients with ventricular tachycardia, in 32 of 33 with atrial flutter and in 21 of 28 patients with supraventricular tachycardia. However, in 7 of 33 patients with atrial flutter, the arrhythmia returned after 6 months. Patient growth continued in the same percentiles achieved before amiodarone in all but eight patients, improving in six and worsening in two with severe underlying disease. Proarrhythmia occurred in three patients: one had torsade de pointes that disappeared when amiodarone administration was stopped; two with severe anatomic heart disease died suddenly during the loading period (one with atrial flutter and one with ventricular tachycardia). Side effects occurred in 28 (29%) of the 95 patients: keratopathy (in 11), abnormal thyroid function test (in 6), chemical hepatitis (in 3), rash (in 3), peripheral neuropathy (in 2), hypertension (in 1) and vomiting (in 1). All side effects disappeared when amiodarone was discontinued or the dose was reduced.(ABSTRACT TRUNCATED AT 250 WORDS)

A 64-yr-old woman developed acute hepatitis after 3 wk of treatment with 40 mg/day of piroxicam (Feldene). Jaundice was preceded by a skin rash associated with eosinophilia. Despite withdrawal of the drug, she developed severe hepatocellular failure and died 53 days after the onset. Hepatitis was attributed to piroxicam because of the absence of other etiological factors.

Severe hepatotoxicity from phenobarbital occurred in an infant boy who had a complicated illness with chronic bilateral subdural hematomas and sepsis. Skin rash began after 2 weeks of treatment, and signs of hepatocellular failure developed 3 weeks after phenobarbital had been started. Signs of severe liver disease included elevated aminotransferases, conjugated hyperbilirubinemia, significant coagulopathy, hepatosplenomegaly and ascites. Other features of this adverse drug reaction were unremitting fever, leukocytosis with eosinophilia and atypical lymphocytosis, and proteinuria. Sepsis, viral hepatitis, and metabolic liver disease were excluded. The child was on no other medication and had been previously well. In-vitro rechallenge of the patient's lymphocytes with cytochrome P-450 generated metabolites of phenobarbital showed extensive cytotoxicity compared to control. These data support the hypothesis that a defect in drug detoxification was responsible for the child's susceptibility to this drug hepatotoxicity.
