At 6 months, the HD group had significantly higher levels of anti-inflammatory markers IL1-RA (705 ± 160 vs. 306 ± 36 pg/mL; p = 0.02) and IL-10 (321 ± 27 vs. 251 ± 28 pg/mL; p = 0.02); and lower levels of proinflammatory marker TNF-α (74 ± 23 vs. 115 ± 15 pg/mL; p = 0.04) compared to LD group. Here, TNF is linked to rheumatoid arthritis.
