Anticonvulsant HSR

A triad of fever, skin eruption and internal organ involvement signal anticonvulsant HSR, a potentially life-threatening syndrome (Figure 1). HSR occurs most frequently with the first exposure to the drug, with initial symptoms starting one to six weeks after exposure to the drug. In previously sensitized individuals, anticonvulsant HSR may occur within one day on rechallenge. This reaction occurs in approximately one/ 10,000 exposures; anticonvulsants, sulphonamide antibiotics, dapsone and allopurinol have been most frequently associated with HSR.

Fever and malaise, which can be accompanied by pharyngitis and cervical lymphadenopathy, are the presenting symptoms in most patients. Atypical lymphocytosis, with subsequent eosinophilia, may occur during the initial phases of the reaction in a subset of patients. A drug eruption occurs in approximately 90% of patients and can range from an exanthematous eruption to more serious SJS or TEN. The liver is the most frequently involved internal organ in anticonvulsant HSR, although other organs such as the kidney (eg, interstitial nephritis, vasculitis), central nervous system (eg, encephalitis, aseptic meningitis), heart (eg, myocarditis) or lungs (eg, interstitial pneumonitis, respiratory distress syndrome, vasculitis) may be involved . In some patients, extensive organ involvement evolves as part of the anticonvulsant HSR. For example, a woman developed skin rash, fever and eosinophilia three weeks after starting carbamazepine. Fulminant respiratory and renal failure ensued. Autopsy showed pneumonitis, nephritis, serositis, pancreatitis, hepatitis and carditis . A small subgroup of patients may become hypothyroid, as part of an autoimmune thyroiditis, within two months of initiation of symptoms.
