Abstract
Subject headings
Close
- Lumbar puncture is recommended for individuals with syphilis who have neurological symptoms, however symptoms have poor sensitivity for predicting symptomatic neurosyphilis. Neurofilament light chain (NfL) is a marker for neuroaxonal injury; cerebrospinal fluid concentrations are higher in symptomatic neurosyphilis than in uncomplicated syphilis or asymptomatic neurosyphilis.Serum NfL was quantified in 20 individuals with uncomplicated syphilis, 10 with asymptomatic neurosyphilis and 10 with symptomatic neurosyphilis using an ultrasensitive single molecule array assay; it was repeated a median of 12.5 months after neurosyphilis therapy. Serum NfL concentration was age-adjusted using a published formula.Age-adjusted serum NfL concentration was significantly higher in symptomatic neurosyphilis compared to each of the other two groups. It was above the highest value in uncomplicated syphilis in one of 10 participants with asymptomatic neurosyphilis and 3 of 10 with symptomatic neurosyphilis. Serum NfL concentration increased in one participant with asymptomatic neurosyphilis with possible treatment failure.If confirmed in a larger study, serum NfL may be a useful adjunct for identifying central nervous system infection by T. pallidum.
