title: [Clinical value of antibody titers to Borrelia burgdorferi and titer course in neurologic disease pictures].
abstract: Over a period of 3 years, antibody titres against Borrelia burgdorferi in serum were determined for 492 patients with a wide spectrum of neurological diseases. Using the ELISA technique, we found elevated titres against Borrelia burgdorferi in about 20% of these patients. Cranial nerve paresis was often the leading symptom of an acute Neuroborreliosis. In a number of cases the diagnosis was indicated only by an elevated IgG titre in the patient's serum, or a decrease in the titre level following antibiotic treatment. The IgG titres are, however, unsuitable for control of therapy. Non-specific parameters of inflammation such as blood sedimentation rate (BSC), C-reactive protein (CRP), serum-electrophoresis or leucocyte count are also unsuitable in evaluating the therapeutic effect or for confirming the diagnosis. The most important diagnostic criterion is the demonstration of Borrelian antibodies, synthesised locally in cerebrospinal fluid (CSF). A spirochaete index above 2 suggests autochthonous intrathecal antibody production. This procedure corresponds to the determination of intrathecally produced Treponema pallidum antibodies in neurolues from quantitative TPHA values and total IgG in serum and CSF (ITpA Index according to Prange).
