| IL-8 | 272 | (115–4,500) | 241 | (102–3,033) | NS |
| TNF-α | 13.5 | (9–44) | 11 | (0.1–32) | NS |
| IFN-γ | 103.5 | (9–323) | 89 | (62–134) | NS |
| IL-2 | 26.5 | (9–34) | 38 | (31–78) | 0.017 |

| IL-10 | 17.5 | (5–22) | 10 | (2–28) | NS |
| IL-17 | <25 | <25 | NS | ||
| Perforin | 1168 | (428–2,010) | 278 | (132–642) | 0.005 |
| Granzyme B | <15 | (<15–56) | <15 | (<15–41) | NS |
The cytokines as well as perforin and granzyme B were detected by enzyme-linked immunosorbent assay and are expressed as picograms per milliliter. Data are presented as median (range). IFN-γ, interferon-gamma; IL, interleukin; NS, non-significant; TNF-α, tumour necrosis factor-alpha.
