In the present study the ratio of antigen-bound anti-IgG-Fab antibodies (hidden aFab) to free aFab was found to be significantly increased in patients with adult onset rheumatoid arthritis (AORA) as compared to late onset rheumatoid arthritis (LORA). The overall amount of aFab was similar in both groups. The difference was only seen in seropositive patients. Within the seropositive AORA group, the aFab ratio was correlated with the duration and the stage of disease but not with the patients' age at investigation. This might reflect a higher affinity of anti-Fab antibodies and/or a greater diversity of the idiotypic repertoire in adult onset disease resulting in the formation of immune complexes, the stability of which might be enhanced further by the presence of rheumatoid factors. Although a pathophysiological involvement of aFab cannot be concluded from our observations, it is conceivable that different immunoregulatory mechanisms could be operative in RA with onset at different ages.
