Abstract and Introduction

Abstract

Lyme disease is the most common human tick-borne disease in the northern hemisphere. This article describes the current knowledge of several aspects of Lyme neuroborreliosis. The epidemiology is reviewed first, with special respect to the difference between European and American disease. Then, the current knowledge about the pathogenesis of Lyme neuroborreliosis is presented, with emphasis on immune evasion strategies. Furthermore, the clinical picture of acute Lyme neuroborreliosis and the frequently discussed post-Lyme disease syndrome are critically discussed. The commonly used diagnostic strategies, as well as the relevance of the lymphocyte transformation test, CD57+/CD3- cell count and CXCL13, are presented. Finally, the therapeutic options are described to give a balanced overview of all aspects of this disease.

Introduction

Lyme borreliosis is the most common human tick-borne disease in the northern hemisphere. The responsible pathogen is Borrelia burgdorferi sensu lato, a spirochete with a length between 5 and 30 µm (Figure 1). In Europe, at least five species of B. burgdorferi sensu lato are pathogenic for human, namely B. burgdorferi sensu stricto, Borrelia garinii, Borrelia afzelii, Borrelia spielmanii and the recently discovered Borrelia bavariensis.[1–3]Borrelia valisiana, Borrelia lusitaniae and Borrelia bissettii have been detected in either cerebrospinal fluid (CSF)[3,4] or erythema migrans,[5,6] but the pathogenicity for humans of these species has not been proven yet.[3] In contrast to this, B. burgdorferi sensu stricto represents the only human-pathogenic species in North America.
