Stevens–Johnson (SJ) syndrome is relatively a rare and potentially a life-threatening condition most commonly triggered by antiepileptic drugs. Most commonly, syndrome presents as fever, unexplained widespread skin pain with red-purple skin rashes, and blisters over skin and mucous membrane of mouth, nose, eyes, and genitals along with the epidermal detachment. Early diagnosis and withdrawal of all the potential causative drugs are essential to prevent rare unfavorable outcomes, such as cellulitis, septicemia, and death.
Recently, we came across a case of a 31-year-old Indian female patient with a history of 11 years of schizoaffective disorder with multiple admissions and treatments received. During her recent exacerbation of illness, she was started with tablet carbamazepine 300 mg/day, tablet escitalopram 10 mg/day, tablet olanzapine 10 mg/day, tablet trifluoperazine 10 mg/day, and tablet zolpidem 5 mg/day. As she failed to improve, tablet lamotrigine 250 mg/day was added straightway. After 5 days of starting lamotrigine, the patient presented with a complaint of swelling over face, redness in both eyes, blisters over face, hands, and trunk region, and high-grade fever followed by inability to eat and take fluids orally. Immediately, she was admitted to a tertiary care hospital. On examination, oral cavity and both upper and lower lip mucosa were bloodstained and ulcerated. Multiple crusted plaques of varying size (1 cm × 2 cm to 3 cm × 5 cm) were found over the face, arms, forearms, and trunk region [Figure 1] and [Figure 2]. On ophthalmological examination, both eyes were congested with yellowish discharge, there was anterior blepharitis, and both eyelids were edematous with exfoliation. The patient was diagnosed to have drug-induced hypersensitivity reaction. All the medications were stopped. The patient was treated with steroids, antihistamines, and supportive treatments.
A schizoaffective disorder is likely to be treated with more than one antiepileptic drug, but the combination of antiepileptic drugs (as mood stabilizers) is found to increase the incidence of SJ syndrome. In this case, the patient was treated with carbamazepine and lamotrigine, both of which can cause SJ syndrome. While prescribing antiepileptic medications, slow dose acceleration and continuous monitoring are advisable to prevent such fatal adverse drug reactions. In this patient, 250 mg lamotrigine per day was abruptly started. Previously done case reports emphasize that even a single higher dose of lamotrigine could increase the risk to develop SJ syndrome, particularly in patients receiving other antiepileptic drugs. Early diagnosis and withdrawal of suspected causative drugs are essential for favorable outcome. In cases like this, when there is exposure to more than one causative agent, and when clinical picture is the same for both, it is difficult to differentiate which one of them may have caused the SJ syndrome. One of the previous studies of 30 cases of SJ syndrome found that more than one positive drug plays a role in 70% of cases. Although it is important to find out which of the antiepileptic must have caused the SJ syndrome so that re-administration of similar drugs can be avoided in such patient, it poses a diagnostic challenge.
