PCSK9 inhibitor significantly reduced the risk of SLE (OR [95%CI] = 0.47 [0.30 to 0.76], p = 1.74 × 10−3) but increased the risk of asthma (OR [95%CI] = 1.15 [1.03 to 1.29], p = 1.68 × 10−2) and CD (OR [95%CI] = 1.38 [1.05 to 1.83], p = 2.28 × 10−2). This evidence concerns the gene PCSK9 and systemic lupus erythematosus.
