Pregnancy and neonatal outcomes in infertile patients with positive tuberculin skin test results

Do infertile women with positive tuberculin skin test (TST) results have a higher risk of adverse pregnancy outcomes after IVF or intracytoplasmic sperm injection and embryo transfer (ICSI-ET) and does preventive anti-tuberculosis treatment applied to infertile women with positive TST results before IVF/ICSI-ET affect pregnancy and neonatal outcomes?This was a retrospective cohort analysis of 6283 infertile women who underwent IVF/ICSI-ET treatment for the first time at the Reproductive Hospital affiliated to Shandong University from November 2016 to September 2022. None of the participants had prior tuberculosis or active tuberculosis. According to their TST results, 5947 patients who had never received preventive anti-tuberculosis treatment were divided into a TST-positive group (1704 cases) and a TST-negative group (4243 cases). A total of 504 patients with TST (+++) results (using the 20 mm sclerosis threshold) were divided into a treated TST (+++) group (336 cases) and an untreated TST (+++) group (168 cases) according to whether they received preventive anti-tuberculosis treatment before IVF/ICSI-ET. The outcome measures were pregnancy outcomes and neonatal outcomes.There were no significant differences in pregnancy or neonatal outcomes between the TST-positive group and the TST-negative group (P > 0.05). In the TST (+++) group, there were no significant differences in pregnancy or neonatal outcomes between the treated TST (+++) group and the untreated TST (+++) group (P > 0.05).For infertile women undergoing IVF/ICSI-ET without prior tuberculosis or active tuberculosis, positive TST results and preventive anti-tuberculosis treatments prior to IVF/ICSI-ET do not affect pregnancy or neonatal outcomes.
