Acquired Holmes Tremor in a Human Immunodeficiency Virus Immune Reconstitution Inflammatory Syndrome Patient Treated with Deep Brain Stimulation.

Abstract

The authors present a case of a 66-year-old male who was diagnosed with human immunodeficiency virus, and his medical course of highly active antiretroviral therapy was complicated with the development of immune reconstitution inflammatory syndrome, which led to development of movement disorder consisting of right-sided resting tremor, neck dystonia, and jaw clenching. The patient's symptoms resembled that of rubral tremor, and he underwent placement of a deep brain stimulation electrode into the left ventral intermediate nucleus of the thalamus with significant improvement of symptoms. This is the first reported case in the literature of a human immunodeficiency virus-positive patient's treatment course complicated with immune reconstitution inflammatory syndrome with neurologic manifestation, which was refractory to medical therapy and thus treated with deep brain stimulation.
