A 14-year-old female developed systemic lupus erythematosus (SLE)-like symptoms, rash, fever, leukopenia and positive anti-nuclear antibody (ANA) two weeks after administration of carbamazepine (CBZ; Tegretol) used against benign Rolandic epilepsy. Clinical symptoms and leukopenia normalized after discontinuation of CBZ and administration of prednisolone at 40 mg. The cases of CBZ-induced SLE reported in the literature were reviewed.

Carbamazepine induced systemic lupus erythematosus is a very rare phenomenon. Seven cases have been reported so far. We report another case documented with both clinical and serologic data and discuss some possible variations in related serology.

Carbamazepine, a widely used anticonvulsant, is associated with a wide range of adverse reactions including agranulocytosis, aplastic anemia and drug-induced lupus. It has also been reported to alter immune function in a variety of ways. We had previously demonstrated that carbamazepine is oxidized by activated neutrophils to several metabolites and this leads to covalent binding of the drug to the cells. It appears that the major metabolite responsible for this binding is 9-acridine carboxyaldehyde. In this study the effects on leukocyte function of carbamazepine and its leukocyte-generated metabolites were compared. Incubation of lymphocytes with 100 microM 9-acridine carboxaldehyde resulted in 40% cell death while carbamazepine at this concentration had no effect on viability. The effect on the immune cell function was investigated using the autologous mixed lymphocyte reaction (AMLR), allogeneic mixed lymphocyte reaction (MLR), lymphocyte transformation test (LTT) and mitogenesis assays. Alteration of immune cell function by the reactive metabolite, 9-acridine carboxyaldehyde, was demonstrated by an increased proliferation at low concentrations (0.08-1.0 microM) and inhibition at high concentrations (20-100 microM) in the allogeneic MLRs. Carbamazepine had no measurable effect. 9-Acridine appears to have more of an effect on B-cells since this augmentation-suppression phenomenon was also observed in mitogenesis assays with Staphylococcus aureus, a B-cell mitogen, in contrast to mostly inhibition observed in the mitogenesis assay with phytohemagglutinin, a T-cell mitogen. Again, carbamazepine had no measurable effects at comparable concentrations.(ABSTRACT TRUNCATED AT 250 WORDS)

Carbamazepine is an anticonvulsant which is associated with a significant incidence of hypersensitivity reactions including agranulocytosis. We have postulated that many drug hypersensitivity reactions, especially agranulocytosis and lupus, are due to reactive metabolites generated by the myeloperoxidase (MPO) (EC 1.11.1.7) system of neutrophils and monocytes. This led to a study of the metabolism and covalent binding of carbamazepine with MPO/H2O2/Cl- and neutrophils. Metabolism and covalent binding were observed in both systems and the same pathway appeared to be involved; however, the metabolism observed with the MPO system was approximately 500-fold greater than that observed with neutrophils. The metabolites identified were an intermediate aldehyde, 9-acridine carboxaldehyde, acridine, acridone, choloroacridone, and dichloroacridone. We postulate that the first intermediate in the metabolism of carbamazepine is a carbonium ion formed by reaction of hypochlorous acid (HOCl) with the 10,11 double bond. Although we have no direct proof for the proposed carbonium ion, it provides the most likely mechanism for the observed ring contraction. Iminostilbene, a known metabolite of carbamazepine, was also metabolized by a similar pathway leading to ring contraction; however, the rate was much faster and the first step may involve N-chlorination and a nitrenium ion intermediate. These data confirm that carbamazepine is metabolized to reactive intermediates by activated leukocytes. Such metabolites could be responsible for some of the adverse reactions associated with carbamazepine, especially reactions such as agranulocytosis and lupus which involve leukocytes.

Carbamazepine-induced lupus is uncommon; its frequency is less than 0.001% of the cases of lupus treated. Herein we describe a 52-year-old woman who had development of facial erythema, arthralgia, dyspnea, and multiple pulmonary rounded masses and nodules while she was taking carbamazepine for epilepsy. Pulmonary histologic examination showed bronchiolitis obliterans organizing pneumonia. Antinuclear antibodies and antihistone antibodies were present without antibodies to double-stranded DNA. Thirteen months after carbamazepine had been withdrawn, all symptoms had disappeared without the use of anti-inflammatory drugs. Even though pulmonary involvement is possible during carbamazepine treatment, to our knowledge, bronchiolitis obliterans organizing pneumonia on its own or associated with carbamazepine-induced lupus has not been previously described.

Carbamazepine has been used successfully in the treatment of different movement disorders and was recently reported to be effective for nonhereditary chorea. In view of the significant side effects associated with the drugs currently used to treat chorea, we sought to further evaluate the efficacy of carbamazepine in children with rheumatic chorea. The study was prospective and included 10 children with chorea (eight females and two males; age range = 7-16 years) referred to our Pediatric Rheumatology Clinic between 1995 and 1999. Nine had rheumatic fever and one had antiphospholipid antibody syndrome that later evolved to systemic lupus erythematosus. All were treated with carbamazepine. Improvement was evident within 2-14 days of initiation of low doses of carbamazepine (4-10 mg/kg daily). The plasma drug levels were 2.8-8.2 microg/mL (therapeutic antiepileptic range = 8-12 microg/mL). The chorea disappeared within 2-12 weeks. The duration of treatment was 1-15 months. No side effects were observed. Recurrence was observed in three patients who received a second trial of carbamazepine with a good response. We suggest that carbamazepine may serve as a first-line treatment for rheumatic chorea.

Drug-induced lupus is a disease, inducible by several drugs, that shares symptoms and laboratory characteristics with idiopathic lupus erythematosus. We report a case of carbamazepine-induced cutaneous lupus erythematosus which developed after 5 years of treatment in a patient who was on this medication because of an epileptic crisis after cranial trauma. Carbamazepine is a medication rarely implicated in drug-induced cutaneous lupus, moreover there are very few reports of such long periods between the start of therapy and the presentation of the clinical symptoms. We describe this case to emphasize the possibility of cutaneous lupus induction by carbamazepine even after many years of therapy.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is an uncommon, life-threatening drug reaction. The basic findings are skin rash, multiorgan involvement, and eosinophilia. Most of the aromatic anticonvulsants, such as phenytoin, phenobarbital and carbamazepine can induce DRESS. Herein we report a 14-year-old patient with DRESS syndrome related to carbamazepine use. The patient presented with signs of involvement of the skin, lungs, liver, and microscopic hematuria. Carbamazepine treatment was discontinued; antihistamines and steroids were started. Hyperglycemia, commencing on the first dose of the steroid given, persisted even after the discontinuation of steroids and improvement of other signs. There were no signs of pancreatitis or type 1 diabetes clinically in laboratory tests. Her blood glucose levels were regulated at first with insulin and later with metformin. Within 1 year of follow-up, still regulated with oral antidiabetics, she has been diagnosed with type 2 diabetes. Formerly, long-term sequelae related to "drug rash with eosinophilia and systemic symptoms syndrome" such as hepatic and renal failure, type 1 diabetes mellitus, Grave's disease, autoimmune hemolytic anemia, and lupus have also been reported. However, up to date, no cases with type 2 diabetes have been reported as long-term sequelae. To our knowledge, this is the first case in the literature presenting with type 2 diabetes as long-term sequelae.
