- AB The current studies examined whether cytokine patterns indicative of an
- imbalance in Th1 and Th2 cells could be identified in PBMC of patients
- with active rheumatoid arthritis (RA). To investigate this possibility,
- a reproducible PCR technique to assess cytokine mRNA levels in PBMC was
- employed that minimized in vitro manipulation of the cells. Seven of 14
- RA patients had increased mRNA levels for IL-2, 5/14 for IFN-gamma, 3/14
- for IL-4, and 4/14 for the IL-2R alpha-chain, compared with normal
- donors. Whereas 4 patients had elevated mRNA for IL-2 and IFN-gamma,
- indicative of an increase in activated Th1 or Th0 cells, 1 of 14
- patients expressed low levels of IL-2 and IFN-gamma and high levels of
- IL-4 mRNA. Seven RA patients were treated with a mAb to ICAM-1 (CD54).
- To determine whether changes in cytokine mRNA levels might be associated
- with and/or account for the anti-inflammatory effect of anti-ICAM-1 mAb
- therapy, changes in cytokine mRNA levels were assessed and correlated
- with clinical improvement. Anti-ICAM-1 mAb administration was followed
- by a prompt and transient increase of IFN-gamma mRNA. Elevation of
- IFN-gamma mRNA expression throughout the treatment period reflected a
- temporary increase in the number of circulating CD3+CD4+ T cells,
- suggestive of altered circulatory patterns of activated Th1-like cells
- and was related to clinical efficacy. The results indicate that elevated
- cytokine mRNA levels characteristic for Th1 cells can be detected in the
- PBMC in active RA and, furthermore, that anti-ICAM-1 mAb may be
- beneficial in RA by altering the recruitment of activated Th1-like cells
- into the synovium. This assumption further strengthens the hypothesis of
- a significant contribution of Th1-like cells to the pathogenesis of RA.
