Brief Summary:
The main purpose of this study is to determine whether four weeks treatment with oral doxycycline is as equally effective as three weeks treatment with intravenous ceftriaxone in patients with Lyme neuroborreliosis. The other purpose is to improve laboratory diagnostics of Lyme neuroborreliosis and further define the manifestations and epidemiology of the disease in Finland.

Condition or disease Intervention/treatment Phase
Lyme Neuroborreliosis Drug: Doxycycline Drug: Ceftriaxone Phase 4

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 210 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Study of Lyme Neuroborreliosis: Epidemiology, Manifestations, Diagnostics and Treatment
Actual Study Start Date : August 2012
Actual Primary Completion Date : December 31, 2017
Actual Study Completion Date : December 31, 2018

Arm Intervention/treatment
Active Comparator: Ceftriaxone
Treatment of intravenous ceftriaxone (2 g/day), three weeks
Drug: Ceftriaxone
2 g intravenous once a day, three weeks

Experimental: Doxycycline
Treatment with oral doxycycline (200mg / day), four weeks
Drug: Doxycycline
Doxycycline: 100mg tablet two times per day, four weeks

Primary Outcome Measures :
  1. The improvement of the clinical condition during the study. [ Time Frame: 12 months ]
    The clinical condition of participants will be evaluated with visual analogue scale (from 0 to 10, 0=best) by the participants. The VAS scores are collected before the treatment with antibiotics, and 4 months and 12 months after the treatment.

  2. The clinical condition evaluated by the participants after 12 months from the treatment [ Time Frame: 12 months ]
    The clinical condition is evaluated with VAS by the participants.

Secondary Outcome Measures :
  1. Central spinal fluid (CSF) pleocytosis [ Time Frame: 3 weeks ]
    The decline in CSF leukocyte count between the patients in doxycycline and ceftriaxone groups

  2. CSF protein concentration [ Time Frame: 3 weeks ]
    The decline in CSF protein concentration between the patients in doxycycline and ceftriaxone groups.

  3. CSF lactate level [ Time Frame: 3 weeks ]
    The decline in CSF lactate level between the patients in doxycycline and ceftriaxone groups.

  4. CSF CXCL13 concentration [ Time Frame: 3 weeks ]
    The decline in CSF CXCL13 concentration wetween the patients in doxycycline and ceftriaxone groups
