摘要:

Markers of cell-mediated immune activation were studied in 32 Chinese patients with recent-onset insulin-dependent diabetes mellitus (IDDM) as compared with 12 patients with recent-onset non-insulin-dependent diabetes mellitus (NIDDM) and 34 normal subjects. Sera were assessed for soluble markers of T-cell activation (sCD4, sCD8, sIL-2R); the cytokines (IL-1β, TNF-α, IL-2, IL-6), and T-cell subsets were also determined. Only 1 of the 32 IDDM patients had increased sCD4 levels, 5 had increased sCD8, and 3 had increased sIL-2R. None of the sera from NIDDM patients and control subjects showed such increased levels of soluble markers. Three IDDM patients had detectable IL-1β and this weakly so (<3.5 pg/ml). However, the other cytokine data and the frequency of activated T-cells, CD4+, CD8+ T-cell subsets and CD4:CD8 ratio showed no significant differences among the IDDM, NIDDM and normal subjects. Our data suggest that in addition to a low frequency of islet cell antibodies, Chinese patients with recent onset IDDM also showed a lack of serum markers of cellular activation.
