Possible N -methyl- D -aspartate receptor antibody-mediated encephalitis in the setting of HIV cerebrospinal fluid escape

We report two adults infected with HIV presenting with encephalopathy and seizures. Case 1 had a monophasic encephalopathy with detection of NMDAR antibodies in the context of HIV CSF escape. There was a clinical response to immunotherapy and anti-retroviral therapy adjustment. Case 2 initially presented in non-convulsive status epilepticus associated with HIV CSF escape. He responded to treatment with anti-epileptic drugs and anti-retroviral therapy alteration, but had two further neurological relapses. NMDAR antibodies were detected during the relapses and a clinical response was observed following treatment with immunotherapy. Clinicians should consider autoimmune encephalitis in HIV infected patients presenting with encephalopathy and seizures, particularly in cases with concomitant HIV CSF escape.
