title: Syphilitic polyradiculopathy in an HIV-positive man.
abstract: We report a case of syphilitic lumbosacral polyradiculopathy in an HIV-positive, 22-year-old bisexual man with a recent history of secondary syphilis treated with intramuscular penicillin. He presented with rapidly progressive pain and weakness, and muscle wasting in the legs. CSF was under increased pressure and showed a marked pleocytosis (1,130 cells/mm3), hypoglycorrhachia (19 mg/dl), and very elevated protein (1,000 mg/dl). Serum and CSF VDRL serologies were positive. In the legs, nerve conduction studies and needle EMG were consistent with an asymmetric lumbosacral polyradiculopathy with active denervation. His clinical state, CSF, and electrophysiologic studies all improved promptly and markedly after intravenous penicillin. This report documents an uncharacteristically aggressive case of neurosyphilis accompanied by marked changes in the CSF in an HIV-positive patient. While the immunologic effects of HIV and syphilis in combination are not yet fully understood, the cellular immunity defect associated with HIV may alter the natural history of syphilis in patients with concomitant infection, producing unusually aggressive forms or atypical presentations of neurosyphilis.
