Early Lyme Neuroborreliosis: Persistent Neurological Symptoms After Initial Antibiotic Treatment
In early Lyme neuroborreliosis, neurological symptoms develop several weeks to several months after a tick bite. When first-line antibiotic treatment does not achieve full resolution, a structured next step is required.
Clinical Scenario
Painful meningopolyradiculitis of the spinal nerves with unilateral or bilateral facial paresis (Bannwarth syndrome), or meningitis in children, arising in the weeks to months following a tick bite. Symptoms can persist for weeks to months after onset.
Prior Treatment & Failure Condition
A completed first-line antibiotic course (doxycycline, ceftriaxone, cefotaxime, or penicillin G) was the initial approach. Escalation to this protocol applies when the expected goals were not met: resolution of neurological clinical symptoms and regression of CSF pleocytosis. If impairing symptoms persist six months after treatment, CSF is re-tested; persisting pleocytosis confirms treatment failure.
Next-Line Approach (Partial Overview)
When persisting pleocytosis is confirmed and alternative diagnoses have been excluded, the protocol involves a renewed course of antibiotic therapy. The full selection criteria, agent choice, and sequencing remain in the complete regimen.

- If a patient continues to have impairing symptoms 6 months after treatment, CSF testing should be repeated; if there are doubts that the symptoms are improving, an earlier CSF follow-up analysis can be considered; if pleocytosis persists, a new course of antibiotic treatment should be carried out after other diagnoses have been ruled out.
