Abstract: The objective of this follow-up study was to determine the long-term outcome of strictly classified cases of neuroborreliosis treated with antibiotics.
A one-year prospective population-based survey of Lyme borreliosis was conducted in southern Sweden, between 1992 and 1993. A total of 349 identified cases with suspected neuroborreliosis were followed up 5 years later. Medical records were reviewed and all participants filled in a questionnaire. Of those classified with definite neuroborreliosis 114/130 completed the follow-up, of whom 111 had completed the initial antibiotic treatment. Of the 114 patients followed up, 86 (75%) had recovered completely and 70 (61%) had recovered within 6 months. Residual neurological symptoms such as facial palsy, concentration disorder, paresthesia and/or neuropathy were reported by 28/114. No significant differences between different antibiotic treatments were observed in terms of occurrence of sequelae.
To conclude, we found that 25% (95% confidence interval 17-33%) of the patients suffered from residual neurological symptoms 5 years post-treatment. However, the clinical outcome of treated neuroborreliosis is favourable as only 14/114 (12%) of the patients had sequelae that influenced their daily activity post-treatment. Early diagnosis and treatment would seem to be of great importance in order to avoid such sequelae.
