The baseline measure of TNF-α/IL-10 cytokine ratio of patients who were less susceptible to multiple infection episodes during the course of their recovery (≤2 total episodes) was 0.200 ± 0.154, significantly higher compared to hypersusceptible patients who experienced repeated infection episodes (≥3 total episodes), with mean TNF-α/IL-10 cytokine of 0.067 ± 0.072 (p = 0.0029) (Figure 2A). Here, TNF is linked to infection.
