Maturity onset diabetes of the young in pregnancy: management, treatment and neonatal outcomes-a systematic review.

Maturity Onset Diabetes of the Young (MODY) is a type of genetically inherited diabetes. As it generally arises in early adulthood, it can affect pregnant women with significant neonatal outcomes. Our study aimed to conduct a systematic review on pregnancy management and outcomes of all subtypes of MODY, browsing the Cochrane, EMBASE and PubMed databases to find clinical studies on the topic. They were last searched on June 29, 2025. The inclusion criteria for our review were: published articles, available in their full-text version, about MODY, reporting data about its management during pregnancy and neonatal outcomes, in English language, specifying therapeutic approaches used. The exclusion criteria were: study designs reported below, written in other languages, not present in above mentioned databases. The risk of bias was assessed through the ROBIS tool. Our systematic review analyzed data on 1408 live births of 1183 pregnant women, and found specific guidelines for the management of pregnant women affected with GCK-MODY and HNF1A-MODY, but none on rarer subtypes. Thus, indications on pregnancy management and outcomes of rarer MODYs were identified through an additional literature review, and its findings were summarized in Table 1. Our systematic review was limited by the lack of data on rarer subtypes of MODY and the specific keywords and databases selected. However, our work lays an important step in the direction of much-needed clinical data and recommendations in treating rare MODY subtypes during pregnancy, towards healthy offspring delivery and growth. A further literature review was carried out to identify any data on other subtypes of MODY and their neonatal outcomes, and the findings were summarized in Table 1. No funding was needed to carry out the present systematic review. PROSPERO registration number: CRD420251062633.
