Acquired transient XXXX in Lyme @entity625 : correlation between rheumatoid factor and disease activity.

@entity1 @entity3001 @entity9144 @entity66 @entity625 @entity2069 @entity792 @entity2401
@entity3001 ( @entity3001 ) is a @entity66 which has been recognized as a separate entity due to its close geographic clustering of affected @entity1 . The study aimed at evaluating the clinical and immunological features of @entity3001 with chronic symptoms of @entity9144 , @entity2401 and pauciarticular @entity625 . Six @entity1 with @entity3001 and erosive @entity625 who developed an increase of serum IgM rheumatoid factor (RF) which correlated with the inflammatory activity of the disease are described in detail. Besides raised IgG antibody titers to @entity2069 (B. burgd.) antigen measured by ELISA technique, circulating immune complexes, antinuclear antibodies (ANA) and RF measured by laser nephelometric immunoassay were detected. Increased ANA and RF antibody rates suggest that @entity3001 may closely be linked with transient @entity792 . Thus, in some cases, B. burgd. antigens might be able to produce a strong polyclonal B-cell stimulation, hence leading to an unspecific @entity792 . But the question remains if transient unspecific @entity792 actually take part in the pathogenesis of @entity3001 .
