Abstract

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.
