A material of 476 hyperthyroid patients treated with carbimazole and 69 patients treated with PTU in the period from 1978 to 1986 were studied retrospectively. The antithyroid treatment was given in low dosage without supplementary thyroxine. The total frequency of adverse effects, defined as symptoms leading to discontinuance of the treatment, was 8.0% for carbimazole and 2.9% for PTU. There were no cases of agranulocytosis in the group treated with carbimazole, and one case in the group treated with PTU. No relationship between age and adverse effects could be demonstrated. The relationship between adverse effects and dosage is discussed, and it is concluded that low dosage treatment with carbimazole has a very low frequency of adverse effects in terms of agranulocytosis and toxic hepatitis.

A 35-year-old woman developed pharyngitis with high fever and painful joint swellings. A severe cholestatic hepatitis occurred 40 days later with a rise of bilirubin to 32 mg/dl. "Nuclear dot" antibodies were demonstrated in the immunofluorescence test on cell cultures, confirming a diagnosis of primary biliary cirrhosis which had followed an atypical course. After nine days of cefotaxime administration, commenced because of persistent fever of 40 degrees C, an agranulocytosis was demonstrated, which regressed within a week of discontinuing the drug. The allergic genesis of the agranulocytosis was proven by repeated lymphocyte stimulation tests in the presence of cefotaxime. The autoimmune hepatitis was probably a predisposing factor in the genesis of the allergically induced agranulocytosis.

The risk of opportunistic infection in the renal transplant patient is due to an interaction between two major factors: the epidemiologic exposures (particularly within the hospital environment) and the net state of immunosuppression. The net state of immunosuppression is determined by the nature, dose, and duration of the immunosuppressive therapy being administered; the presence or absence of granulocytopenia and technical factors that could compromise the primary mucocutaneous barriers to infection; such metabolic factors as uremia, hyperglycemia, and the state of nutrition; and, finally, the immunomodulating effects of such viruses as CMV, the hepatitis viruses, and HIV. The major types of opportunistic infection to which the renal transplant patient is susceptible are the following: the viruses of the herpes group and papovaviruses; bacteria such as L monocytogenes, N asteroides, and Legionella; such fungi as Candida, Aspergillus, C neoformans, and the Mucoraceae; and protozoans such as P carinii, S stercoralis, and T gondii.

The toxicities of antimalarial drugs vary because of the differences in the chemical structures of these compounds. Quinine, the oldest antimalarial, has been used for 300 years. Of the 200 to 300 compounds synthesised since the first synthetic antimalarial, primaquine in 1926, 15 to 20 are currently used for malaria treatment, most of which are quinoline derivatives. Quinoline derivatives, particularly quinine and chloroquine, are highly toxic in overdose. The toxic effects are related to their quinidine-like actions on the heart and include circulatory arrest, cardiogenic shock, conduction disturbances and ventricular arrhythmias. Additional clinical features are obnubilation, coma, convulsions, respiratory depression. Blindness is a frequent complication in quinine overdose. Hypokalaemia is consistently present, although apparently self-correcting, in severe chloroquine poisoning and is a good index of severity. Recent toxicokinetic studies of quinine and chloroquine showed good correlations between dose ingested, serum concentrations and clinical features, and confirmed the inefficacy of haemodialysis, haemoperfusion and peritoneal dialysis for enhancing drug removal. The other quinoline derivatives appear to be less toxic. Amodiaquine may induce side effects such as gastrointestinal symptoms, agranulocytosis and hepatitis. The main feature of primaquine overdose is methaemoglobinaemia. No cases of mefloquine and piperaquine overdose have been reported. Overdose with quinacrine, an acridine derivative, may result in nausea, vomiting, confusion, convulsion and acute psychosis. The dehydrofolate reductase inhibitors used in malaria treatment are sulfadoxine, dapsone, proguanil (chloroguanide), trimethoprim and pyrimethamine. Most of these drugs are given in combination. Proguanil is one of the safest antimalarials. Convulsion, coma and blindness have been reported in pyrimethamine overdose. Sulfadoxine can induce Lyell and Stevens-Johnson syndromes. The main feature of dapsone poisoning is severe methaemoglobinaemia which is related to dapsone and to its metabolites. Recent toxicokinetic studies confirmed the efficacy of oral activated charcoal, haemodialysis and haemoperfusion in enhancing removal of dapsone and its metabolites. No overdose has been reported with artemesinine, a new antimalarial tested in the People's Republic of China. The general management of antimalarial overdose include gastric lavage and symptomatic treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

Individual chemoprophylaxis against malaria remains mandatory for all trips of brief or intermediate duration in endemic areas. The selected anti-malarial drug must be taken regularly from the beginning of the stay, during the stay and for the 30 days after return (The 30 days following the departure from regions at risk). Presently the following drugs are available: amino-4-quinolines, quinine, antifolinic agents, the association antifolinic-antifolic agents and mefloquine. Specific advantages, side-effects and adverse reactions, as well as dosage used for prophylaxis are given for each drug. The risk of agranulocytosis and severe hepatitis related to amodiaquine forbids its use until more information has become available. The association sulfadoxine + pyrimethamine is no longer recommended for prophylaxis by the French authorities and recently by the W.H.O., because of its potential, although seldom, risk of severe muco-cutaneous disorders. Detailed schemes of prophylaxis are given; they rely on sensitivity or resistance of Plasmodia strains, the length of the stay in at risk areas, and the local situation concerning the hazard of infection and drug resistance of Plasmodia. Chloroquine must be used in priority in areas characterized by sensitivity or low grade resistance to chloroquine. In order to avoid resistance to mefloquine, its administration has to be limited to prophylaxis for short stays and to the treatment of attacks resulting from infections acquired in areas known for resistance against the other drugs. Today, indeed, mefloquine is the single agent efficient in case of multiresistance to Plasmodium falciparum. The treatment of suspected or proved cases of malaria attacks occurring in temporary or permanent expatriates or in local, semi-immune residents, has become strongly advisable. In areas of resistance to chloroquine, either quinine (repeated injections), sulfadoxine-pyrimethamine (per os or unique parenteral injection) or if possible, mefloquine (full dose during 1 day) are to be used for the therapy of acute attacks. Continuous chemoprophylaxis is no longer encouraged for populations living in holoendemic areas. Treatment of suspected or overt malaria crises is, however, mandatory. The limitation to curative therapy is opening the way to more specific prophylaxis: pregnancy, delivery, intercurrent pathological events, such as surgery, trauma, infection... It is hoped that, until the forthcoming of anti-malaria immunoprophylaxis, these newly adjusted designs for chemotherapy will help to keep the progress of malaria and the development of plasmodial resistance under control.

After reviewing the literature, the authors demonstrate that pyrithioxine is active in rheumatoid arthritis. The effectiveness is marked by a 50 per cent reduction in the articular index in 59.7 per cent of cases, a reduction in the duration of morning stiffness in 49 per cent of cases, a decreased erythrocyte sedimentation rate in 52.4 per cent of cases and a statistically significant decrease in the mean of these parameters in relation to the mean value at the beginning of treatment. The good results were considered to be those cases in which two of the three criteria (articular index, morning stiffness and erythrocyte sedimentation rate) were decreased by at least 50 per cent. Secondary escapes from treatment (13 per cent) and suspension of treatment for intolerance were considered to represent treatment failures. A good result was obtained in 42.7 per cent of cases. Side effects were observed in 40.1 per cent of cases and were responsible for suspension of treatment in 22.8 per cent of cases. Half of the side effects consisted of muco-cutaneous reactions which generally appeared early and were benign. Haematological, renal and gastrointestinal effects and aguestia occurred more rarely. However, a number of patients died as a result of agranulocytosis, hepatitis or extramembranous glomerulonephritis.

Excluding the most frequent kinds of problems seen with the nonsteroidal antiinflammatory drugs (NSAID)--gastritis, peptic ulceration and renal effects--published reports indicate that these drugs may cause a wide variety of rare adverse reactions. The most serious of these are hypersensitivity reactions: blood dyscrasias (aplastic anemia, thrombocytopenia, agranulocytosis, hemolytic anemia), erythema multiforme and hepatitis. Aseptic meningitis and anaphylactoid reactions may strike patients with underlying immunologic abnormalities; urticaria, bronchospasm and proctocolitis may affect aspirin-sensitive patients. Other unusual reactions include several kinds of bullous dermatitis, febrile reactions, pneumonitis, esophageal ulceration, parotitis, pancreatitis and neurological or psychological effects.

We review the cases of hepatic injury from propylthiouracil, methimazole and carbimazole in the English language literature and compare them to cases of agranulocytosis in a recent review. The data on hepatotoxicity confirm the findings for agranulocytosis that low-dose methimazole is safer than propylthiouracil and that methimazole toxicity is more common over 40 years old. In contrast, propylthiouracil hepatotoxicity often occurs in younger patients. Most cases of hepatic injury occur in the first few months of drug therapy as with agranulocytosis. The reason that methimazole typically causes cholestatic hepatitis while propylthiouracil causes cytotoxic hepatitis remains unknown.

Allogeneic bone marrow grafts carried out after previous administration of antilymphocytic serum alone were attempted in 16 patients. Of these, six had acute myeloblastic leukaemia, four acute lymphoblastic leukaemia, and one a blast cell crisis in polycythaemia vera. Ten of these patients were in an overt phase of the disease and resistant to chemotherapy, while nine had complete agranulocytosis. In five of these patients erythrocyte and leucocyte antigenic markers demonstrated the establishment of the graft. One patient had thalassaemia major, and four others had aplasia of the bone marrow, in one case due to chloramphenicol poisoning and in another to virus hepatitis. The grafts were successful in the last two patients and transformed their clinical condition.No signs of early acute secondary disease were noted in any of the patients, either when the donor had been given antilymphocytic serum or when he was untreated. The grafts had no adoptive immunotherapeutic effect on the acute leukaemia. These observations have clearly shown that antilymphocytic serum has an immunosuppressive effect in man when it is used alone.
