There was a significant association for preterm birth in women with coeliac disease (OR 1.30 (1.13–1.50)), IBD (OR 1.81 (1.37–2.38)), psoriatic diseases (psoriasis OR 1.22 (1.04–1.42), psoriatic arthritis OR 1.48 (1.24–1.78)), rheumatoid arthritis (OR 1.57 (1.00, 2.48)), and systemic sclerosis (OR 2.40 (1.14–4.86)) and for thyroid autoimmunity (all) (OR 1.88 (1.32–2.67) and thyroid autoimmunity (TPO) (OR 1.33 (1.15–1.56)) when compared to women without these conditions [29, 31, 32, 35, 97, 109, 110, 117, 128, 131]. This evidence concerns the gene TPO and systemic sclerosis.
