          Abstract

          Background/Aims: Various abnormalities of the immune system have been demonstrated in patients on hemodialysis (HD). We hypothesize that the imbalance between type 1 helper T (Th1) cells and type 2 helper T (Th2) cells in patients on HD contributes to these abnormalities. Furthermore, we investigate the relationship between the Th1/Th2 imbalance and HD duration. Methods: We measured the serum levels of soluble CD26 (sCD26) and soluble CD30 (sCD30) in 47 patients on HD and in 13 patients with chronic renal failure not on HD and analyzed the effect of HD duration on the serum levels of sCD26 and sCD30. Results: The serum level of sCD26 in the HD group was significantly lower than that in the control group. On the other hand, the serum levels of sCD30 in the HD group and in the CRF group were significantly higher than in the control group. In the short-term HD group (<1 year), the serum levels of sCD26 were lower and the sCD30 levels higher than those in middle-term HD group (1–10 years). Conclusions: In the HD group, the Th1/Th2 balance may shift towards Th2 dominance. It is possible that this imbalance contributes to the abnormality of the immune system in HD patients.

          Two types of mouse T helper cell. IV. Th2 clones secrete a factor that inhibits cytokine production by Th1 clones

          MW Bond, DF Fiorentino, TR Mosmann (1989)
          A cytokine synthesis inhibitory factor (CSIF) is secreted by Th2 clones in response to Con A or antigen stimulation, but is absent in supernatants from Con A-induced Th1 clones. CSIF can inhibit the production of IL-2, IL-3, lymphotoxin (LT)/TNF, IFN-gamma, and granulocyte-macrophage CSF (GM-CSF) by Th1 cells responding to antigen and APC, but Th2 cytokine synthesis is not significantly affected. Transforming growth factor beta (TGF-beta) also inhibits IFN-gamma production, although less effectively than CSIF, whereas IL-2 and IL-4 partially antagonize the activity of CSIF. CSIF inhibition of cytokine synthesis is not complete, since early cytokine synthesis (before 8 h) is not significantly affected, whereas later synthesis is strongly inhibited. In the presence of CSIF, IFN-gamma mRNA levels are reduced slightly at 8, and strongly at 12 h after stimulation. Inhibition of cytokine expression by CSIF is not due to a general reduction in Th1 cell viability, since actin mRNA levels were not reduced, and proliferation of antigen-stimulated cells in response to IL-2, was unaffected. Biochemical characterization, mAbs, and recombinant or purified cytokines showed that CSIF is distinct from IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IFN-gamma, GM-CSF, TGF-beta, TNF, LT, and P40. The potential role of CSIF in crossregulation of Th1 and Th2 responses is discussed.

            Characteristic Cytokine Products of Th1 and Th2 Cells in Hemodialysis Patients

            Yoshihiro Daichou, Satonori Kurashige, Saori Hashimoto … (1999)
            Dysfunction of the host defense against infection in hemodialysis (HD) patients has major clinical and socioeconomic implications. T helper type 1 (Th1) and type 2 (Th2) cytokines are implicated in regulating the immune responses and, therefore, may be involved in impaired status. The present study was designed to examine Th1 and Th2 cytokine profiles in 22 stable HD patients (aged 63 ± 11 years) and 22 healthy controls (aged 60 ± 6 years). The T cell activity was significantly retarded in HD patients as compared with normal persons. The proportions of T cytotoxic/suppressor cells and natural killer cells were significantly higher in HD patients than in controls. In contrast, the proportions of T helper/inducer and B cells were significantly lower in HD patients than in controls. The production of interleukin (IL) 2, which is involved in cell-mediated immune responses, and the production of IL-4 and IL-10, which affect humoral immunity, were significantly lower in patients than in controls. The production of IL-12 by macrophages and of interferon gamma by Th1 cells was significantly higher in HD patients than in controls. The concentration of plasma sIL-2R was significantly higher in patients than in controls. These results suggest that both cellular immunity induced by Th1 and humoral immunity induced by Th2 decrease in HD patients, but that improved IL-12 secretion by macrophages activated natural killer cells to produce interferon gamma, which in turn induced macrophage activity.
