Background The effects of biologicals on reproduction are unknown. Therefore pregnancy during biologicals use is discouraged. However biologicals are frequently prescribed in patients of childbearing potential and many patients become pregnant while using these drugs. Objectives In 2015 EULAR published a broad review article on this matter. Our aim was to update the data based on newly published articles. Methods A search was conducted at 18/10/2017 and then 21/11/2018 in Embase, Medline Ovid, Web Of Science, Cochrane CENTRAL and Google Scholar with specific search terms for each database. Articles were excluded based on title/abstract (double blind, two researchers, NG and HJMJC) and then full text (one researcher, NG). A chart was made based on outcomes of interest(see Table1). The references of included articles were reviewed to include and minimize the missing articles. Results Totally 137 articles were included (79 articles at first round, 51 articles at second round and 7 found after screening the references of the included articles). A descriptive analysis was performed to sum up the data on each separate biological and all the biologicals together. The results are shown in Table1. It should be notified that due to heterogeneity of the data the calculated percentages are up to individual interpretations and cannot be compared to each other. Conclusion From 2015 onwards, there have been many articles published regarding use of biologicals during pregnancy. Despite limitations of our study, such as heterogeneity in being prospective or retrospective and quality of the included articles, no alarm is raised concerning safety issues.
