There appears to be a relationship between retroviruses such as HIV and the development of an ALS-like syndrome. Few cases have been reported; however, there exists evidence of a higher frequency of motor neuron disease in HIV-infected patients, as well as potential slowing and reversibility of disease course with combination antiretroviral therapy. We conducted a retrospective chart review of patients presenting to the George Washington University ALS Clinic from September 2006 to June 2018 to identify patients with HIV receiving HAART who were subsequently diagnosed with ALS or an ALS-like disorder. Our goals were to describe our patients’ disease course and compare them to general characteristics of ALS. We report three cases of HIV-positive individuals, all male, who were subsequently diagnosed with ALS. Each presented with symptoms of limb onset ALS with involvement of upper and lower motor neurons and whose disease originated at the cervical level. All three had been diagnosed with HIV prior to presentation and were presumably compliant with antiretroviral therapy throughout. Our patients demonstrated effective control of their HIV infection. Each experienced relatively slow progression of motor impairment compared to general ALS characteristics. Our study offers a distinct profile of HIV-positive patients compliant with HAART subsequently diagnosed with an ALS-like disorder. Further study should aim to uncover pathophysiological similarities between motor neuron disease both in the presence and absence of retroviral infection and to develop effective medical therapy for each.
