We used a capture ELISA with biotinylated Borrelia burgdorferi flagella as antigen to analyze the kinetics of intrathecal antibody production against B burgdorferi in 27 patients with neuroborreliosis. All patients had lymphocytic pleocytosis, 13/27 had intrathecal specific IgM production, and 26/27 had intrathecal IgG synthesis against B burgdorferi before therapy. All patients improved after antibiotic treatment. At follow-up, 11 months to 8 years later (median, 1 1/2 years), 20 patients had had a complete clinical recovery, and seven suffered from sequelae. One patient without sequelae had persistent specific intrathecal IgM synthesis. Ten of 20 patients without sequelae and five of seven patients with sequelae had persistent intrathecal IgG production against B burgdorferi. None of the 16 patients with persistent specific intrathecal antibody synthesis had pleocytosis at follow-up. Therefore, intrathecal immunoglobulin production against B burgdorferi, especially IgG, may persist for years after treatment of neuroborreliosis without clinical signs of active disease.
To compare the efficacy of oral doxycycline and IV penicillin G for the treatment of neuroborreliosis, we randomized consecutive patients with Lyme neuroborreliosis to receive either IV penicillin G (3 g q 6 h) or oral deoxycycline (200 mg q 24 h) for 14 days. All patients had antibodies against Borrelia burgdorferi in serum, CSF, or both, or had a positive CSF culture. Twenty-three patients randomized to penicillin G and 31 patients to doxycycline were included in the study. All patients improved during treatment, and there were no significant differences between the two treatment groups in patient scoring, CSF analysis, or serologic and clinical follow-up during 1 year. There were no treatment failures, although one patient in each treatment group was re-treated because of residual symptoms. In conclusion, oral doxycycline is an adequate and cost-effective alternative to IV penicillin for the treatment of Lyme neuroborreliosis.
To investigate the duration and kinetics of immunoglobulin M (IgM) and IgG antibodies against Borrelia burgdorferi in serum after treatment of Lyme borreliosis, consecutive serum samples from 30 seropositive patients with erythema migrans and 91 seropositive patients with neuroborreliosis were analyzed with a capture IgM enzyme-linked immunosorbent assay (ELISA) and an indirect IgG ELISA, both using B. burgdorferi flagella as the antigen. All the patients improved after treatment: 97 patients had a complete clinical recovery, while 24 patients had sequelae. The results showed that patients with erythema migrans and early neuroborreliosis more often initially had highly elevated IgM optical density (OD) values and low IgG OD values against B. burgdorferi, while the opposite was found in patients with late neuroborreliosis. During follow-up, the majority of patients had developed negative or significantly declining IgM ODs after 1 to 1.5 years but persistently positive IgM ODs were found up to 17 months after treatment of erythema migrans and 3 years after treatment of neuroborreliosis. IgG antibody levels declined more slowly and remained elevated to a larger extent, but more than half of the patients had developed negative IgG ODs within 5 years after therapy. However, positive IgG OD values were found after 9 to 10 years for patients treated for neuroborreliosis as well as erythema migrans. Both IgM and IgG antibodies against B. burgdorferi may persist for months to years after successful treatment of Lyme borreliosis. Consequently, a single serum sample with antibodies against B. burgdorferi must always be carefully evaluated and correlated to clinical symptoms.
Background and Purpose: Borrelia burgdorferi, the etiologic agent of Lyme disease, can cause different neurological manifestations. We studied the prevalence of Lyme neuroborreliosis in patients with stroke.Methods: During a 1-year period, sera from patients with cerebral thrombosis or transient ischemic attack without cardioembolism were investigated for antibodies against B burgdorferi.Results: One of 281 patients had a positive serum immunoglobulin M titer and 23 of 281 (8%) had positive serum immunoglobulin G titers against B burgdorferi. One of the 24 seropositive patients, with a diagnosis of transient ischemic attack due to dysphasia, had a lymphocytic pleocytosis and intrathecal antibody production against B burgdorferi. The medical history revealed a 9-month period of general and neurological symptoms compatible with Lyme neuroborreliosis before the strokelike incidents.Conclusions: We conclude that Lyme neuroborreliosis may imitate stroke, but screening for antibodies against B burgdorferi seems to be of little value and may be replaced by a careful medical history.

To study the serological response to Borrelia burgdorferi after treatment of late Lyme borreliosis, consecutive serum samples from 20 patients with Borrelia arthritis and 21 with acrodermatitis chronica atrophicans were analysed with capture IgM ELISA and indirect IgG ELISA, both using B. burgdorferi flagella as antigen. Seven patients had positive IgM OD values, whereas all 41 had positive IgG OD values before therapy. In the majority, highly elevated IgG OD values were seen. All patients improved after antibiotic therapy, 32 recovering completely, while 9 had sequelae. At follow-up after 6 months to 5 years, 4/7 patients became negative IgM ELISA, whereas 3 still had slightly elevated IgM OD values 6 months, 1 year and 4.5 years, respectively, after therapy. Only one patient became negative in IgG ELISA during follow-up, although a significant decline in IgG OD values was seen in 22 of the remaining 40 initially IgG-positive patients. The serological response after successful treatment of Borrelia arthritis and acrodermatitis chronica atrophicans may persist for several years even with highly elevated IgG OD values in patients who have recovered completely.
