Evaluation of cerebrospinal fluid in asymptomatic late syphilis.
A prospective study of the cerebrospinal fluid (CSF) of 49 previously untreated patients with asymptomatic late syphilis of more than two year's duration was conducted. The sera of all patients had reactive fluorescent treponemal antibody absorption (FTA-Abs) tests or Treponema pallidum haemagglutination tests (TPHA), and reactive or non-reactive Venereal Disease Research Laboratory (VDRL) tests. Five (10%) patients had abnormal CSF findings; these included elevated protein in four of 49 and pleocytosis in three of 49. Asymptomatic neurosyphilis, diagnosed on the basis of a reactive VDRL test of the CSF, was present in one (2%) of 49 patients.
