Seventy-three patients with undiagnosed arthritis of undetermined aetiology, 94 patients with classified arthritis (rheumatoid arthritis, ankylosing spondylitis, etc.) and 70 controls were studied for clinical and serological manifestations of Lyme borreliosis. The patients were recruited from the three rheumatology units in the most southern part of The Netherlands. A clinical diagnosis of possible Lyme borreliosis was made in seven of 73 patients with arthritis of undetermined aetiology, in four of 94 patients with classified arthritis and in one of the controls. A definite diagnosis of Lyme borreliosis could be made in only one patient who belonged to the arthritis of undetermined aetiology group. This patient had erythema migrans, arthritis of the knee joint and showed positive antibodies to B. burgdorferi. In the southern part of The Netherlands, Lyme arthritis does not seem to be a frequent cause of arthritis of undetermined aetiology.

The categorization in four classes of association between infection and arthritis (namely infective, post-infective, reactive and idiopathic) seems nowadays to be inadequate to cover the extensive field of interactions between infectious agents and host response resulting in arthritis. This paper is a synthetic review of the subject with particular reference to pathogenetic mechanisms in children. An effort has been accomplished, on the basis of the most recent literature, to define the respective roles of the microbial aggression and the host response in a number of conditions: septic arthritis, viral arthritides, Lyme arthritis, rheumatic fever, Reiter's syndrome, ankylosing spondylitis and rheumatoid arthritis.

We tested the sera of 50 patients with Lyme disease for IgM-rheumatoid factor (IgM-RF) using a sensitive ELISA. Levels of IgM-RF greater than 3 SD above the mean of normal subjects were found in 2 of 15 patients with erythema chronicum migrans, 7 of 10 with neurologic abnormalities, and 7 of 25 with Lyme arthritis (p = 0.038). Only 2 of these sera were positive by latex agglutination. In contrast, none of the 23 control patients with osteoarthritis, ankylosing spondylitis, or Reiter's syndrome had positive tests. The levels of IgM-RF correlated with disease activity (p = 0.002), total serum IgM levels (p = 0.002), and specific IgM antibody titers to Borrelia burgdorferi (p = 0.006). IgM-RF reactivity was absorbed with heat aggregated IgG (HAGG), but the titer of specific IgM antibody was insignificantly affected by this procedure. Thus, small amounts of RF are produced at certain times in many patients with Lyme disease, and IgM-RF production appears to be linked to the specific IgM response.

In contrast to rheumatoid arthritis (RA), the triggering antigens are known in reactive arthritis (ReA) and Lyme arthritis. Thus, in these arthritides the antigen-specific T-cell response can be investigated in much detail and lessons possibly learned for other spondyloarthropathies (SpA) such as ankylosing spondylitis (AS) where T cells may well also play an important role in the pathogenesis. This article focusses on the immunopathology of the SpA, ReA, and AS with special reference to T cells and cytokines.
