Isolation of the spirochetes in the perilymph despite prior antisyphilitic therapy: a case report

Insights

Congenital syphilis can cause sensorineural deafness. This case report details a rare instance of persistent treponemes in the inner ear perilymph of a treated congenital syphilis patient.

Area of Science:

  • Otolaryngology
  • Infectious Diseases
  • Pediatrics

Background:

  • Congenital syphilis is a serious infection passed from mother to child.
  • Sensorineural hearing loss is an uncommon complication of congenital syphilis.
  • Treponema pallidum persistence after treatment is rare.

Observation:

  • This case report focuses on a congenital syphilitic patient.
  • The patient exhibited sensorineural deafness.
  • Viable treponemes were found in the inner ear perilymph despite penicillin treatment.

Findings:

  • Demonstrates the rare persistence of viable Treponema pallidum in the inner ear.
  • Highlights an unusual presentation of congenital syphilis with sensorineural deafness.
  • Documents a case where standard penicillin treatment was insufficient to eradicate the infection from the inner ear.

Implications:

  • Suggests a need for further investigation into treatment efficacy for congenital syphilis affecting the inner ear.
  • Underscores the potential for neurological and auditory complications even after treatment.
  • Emphasizes the importance of considering persistent infection in congenital syphilis patients with hearing loss.
