We also found a significantly increased expression of IL6 (p = 0.007) and IL10 (p = 0.003) and decreased IL18 expression (p = 0.029) in the BD-Lithium group compared to the control group, whereas no significant changes in the expression of these genes were found between the BD-OD and the control group. The gene discussed is IL18; the disease is osteochondritis dissecans.
