Abstract

Three infants, ages 3 months to 3 years, presented with chorea as the initial manifestation of herpes simplex encephalitis (HSE) relapse. Patient 2, treated with repeated 10 day courses of 30 mg/kg/day of acyclovir, had no clear improvement in neurological status. Patient 1, treated with a repeated 10-day course, improved only to have another HSE relapse 4 years later. Patient 3 clearly improved soon after a 3-week course of acyclovir at conventional dosages. A fourth patient (Patient 4) who relapsed with chorea after what was thought to be HSE, and who did not respond to repeated acyclovir treatment, was negative for herpes simplex virus indicators on brain biopsy and DNA testing. We recommend treating all patients suffering from HSE with a minimum 3-week course of acyclovir at 30–35 mg/kg/day in 3 divided doses.

    Initially, a proportion of patients with HSE were found to have NMDAR-antibodies in serum and CSF but the clinical significance of these antibodies, and their time course were variable (Pruss et al., 2012). Relapsing choreoathetoid and encephalopathic symptoms in children post-HSE have long been recognised, but were not attributable to direct viral cytotoxicity (Gascon et al., 1993). The discovery that many of these children had de novo generation of NMDAR-antibodies during this relapsing choreoathetoid-encephalopathy, suggested the relapse was mediated by NMDAR-antibodies (Armangue et al., 2014b; Hacohen et al., 2014; Mohammad et al., 2014b).

    It is possible that the first episode of febrile status epilepticus at 12 months of age was also caused by HHV-6 and that the second more severe illness was due to a reactivation of the virus. Chorea has been described as a complication of recurrent herpes simplex virus encephalitis [13-15]. It is also possible that the first episode of febrile status epilepticus was caused by a different virus and was unrelated to the second, more severe illness.

    Rare cases of chronic progressive encephalitic illness have also been described after a first episode of HSE.81–85 The resumption of cerebral viral replication occurring after a first episode of encephalitis has been repeatedly suspected in HSE relapses on the basis of the existence of new necrotic-hemorrhagic lesions distant from the initial site of encephalitis (Fig. 2), positive HSV PCR and/or increased alpha-IFN level in the CSF, reappearance of HSV IgG ITS, isolation of HSV from brain biopsy and/or clinical improvement under a new course of acyclovir treatment.7,9,17,30,69,70,86 In children, these relapses have been described to occur from a few days after acyclovir cessation (early relapse) to months or years after the first HSE episode (late relapse).7

    They suggested that these lesions were attributable to immune-mediated demyelination, as observed in acute disseminated encephalomyelitis. In previous reports, corticosteroids, immunoglobulin, and immunosuppressants were used with variable success to attenuate a possible immune-inflammatory reaction [10-12]. Recently, longitudinal magnetic resonance imaging studies performed in two asymptomatic children after herpes simplex encephalitis infection demonstrated the existence of self-limiting diffuse white-matter lesions, as observed in our case [4,5].
