Background/objective: To determine if anti-RA33 antibodies, which can be seen in early forms of inflammatory arthritis, are present in patients with Lyme arthritis (LA).
Methods: Anti-RA33 antibodies were tested using a commercially available assay in patients with LA (n = 47) and compared with patients with erythema migrans who returned to health (EM RTH, n = 20) and those with post-treatment Lyme disease (PTLD) (n = 50), characterized by noninflammatory arthralgia, as an observational comparative study utilizing Lyme-exposed patients from various original cohorts.
Results: We found that anti-RA33 was present in higher proportions of patients with LA (23.
Background: Anti-annexin A2 (AA2) antibodies have been described in Lyme arthritis and erythema migrans, although they have not been described in post-treatment Lyme disease (PTLD).
Objectives: Determine whether anti-AA2 antibodies are present among patients with PTLD and determine the clinical relevance of these antibodies.
Design And Methods: Anti-AA2 levels were tested serially in a longitudinal cohort of 44 patients with acute Lyme disease, 22 with a return to health (EM RTH), and 22 with PTLD.
