Figure 1 (A) Interleukin-12 (IL-12) production by peripheral blood mononuclear cells (PBMC) in groups A1, A2, B1and B2. The cutoff was 60 U/kg/week for groups A1 and B1, and the cutoff was 100 U/kg/week for groups A2 and B2. (B) Interferon gamma (IFN-γ) production by PBMC in groups A1, A2, B1 and B2. The cutoff was 60 U/kg/week for groups A1 and B1, and the cutoff was 100 U/kg/week for groups A2 and B2. (C) Tumor necrosis factor alpha (TNF-α) production by PBMC in groups A1, A2, B1 and B2. The cutoff was 60 U/kg/week for groups A1 and B1, and the cutoff was 100 U/kg/week for groups A2 and B2. Symbols are: () group A; (▪) group B.

Figure 2 Human recombinant erythropoietin (EPO) requirements in the group of patients with tumor necrosis factor-α (TNF-α) < 2 and interleukin-6 (IL-6) production < 40 (N = 11; ) versus the group of patients with TNF-α ≥ 2ng/ml and IL-6 production ≥ 40ng/ml (N = 14; ▪).

Figure 6 Schematic view of the network of cytokines interactions involved in the deranged regulation of the hemopoiesis. The positive or negative regulations are indicated in the balloons. Data from17,18,26-28 plus the results of our study were combined to draw the cartoon.
