A 21-year-old woman sufferingfrom bipolaraffective disorder developed systemic kipus erythematosus (SLE) with characteristic laboratory findIngs, 18 months after starting carbamazepine maintenance treatment. SLE receded after wlthdrawel of carbemazepine and treatment with anti-Inflammatory drugs. Although both the spontaneous occurrence of SLE and the psychosis as

Remarkably, extrapyramidal movement disorders (acute dystonia) occurred with doses of haloperidol as low as 4mg/day. These were treated with anticholinergics. Because of the rapid cycling course, prophylactic treatment with carbamazepine (400 mg/day) was initiated. Three months later, the patient had completely recovered from

her mood disorder and remainedstable for approximately two years. Eighteen months after initiating carbamazepine treatment, she developed arthritis of the ankle, fmgers, elbows,

Carbamazepinewaswithdrawnand the SLEwastreated with non-steroidal anti-inflammatory drugs (for several months), corticosteroids (for about one year) and disease modifying anti-rheumatic drugs (chloroquine; up to now). The clinicalsignsof SLE subsequentlyimproved considerably within four weeksand receded completelywithin two months

(ds-DNA antibodies 10¾;ANA still remained positive; computerisedtomographyand magneticresonanceimaging of the brain normal). However, the patient had a further episode of affective instability for approximately six months and hospital admission was required three times. At this stage, a maintenance lithium treatment was begun. The chloroquine treatment was continued (for 20 months up to the present moment) to prevent a reappearance of SLE symptoms since a spontaneous SLE cannot be ruled out (see Discussion). The patient's psychiatric illness has been diagnosed as a manic-depressive (bipolar) disorder. Her course of illness is atypical, exhibiting rapid mood shifts from depression to hypomanic or manic states, from the beginning. Discussion

Just as in the previously described cases, the causalrelationship betweencarbamazepine treatment

and the occurrence of SLE in our patient is not unambiguous. However, anti-histone-antibodies, which are more often found in drug-induced SLE

(90%) than in idiopathic SLE (30—70%),constitute an important

argument

for this link.

Generally, three different interpretations are con ceivable: (a) the patient is suffering from a psychiatric disorder and additionally from carbamazepine induced SLE; (b) she exhibits an affective disorder treated with carbamazepine and independently she

developed SLE; (c) at first, she had subclinical SLE with psychiatric symptoms only, which were treated with carbamazepine, the articular manifestations

of SLE occurring later. In fact, neuropsychiatric symptoms of SLE are now being reported in up to 60% of patients, predominantly seizures, but also organic mental syndromes and sometimes functional

psychoses (Lishman, 1990).

However, the identification of anti-histone anti bodies strongly supports the first hypothesis, i.e. the carbamazepine-induction of the SLE in our patient. Furthermore, in agreement with the carbamazepine induced cases already described in the literature, SLE occurred during long-term treatment with

carbamazepine.

Hence, SLE has to be seriously

considered as a possible adverse effect of carbamaze pine treatment. References ALBALLA, S.,
