Italian recommendations for the diagnosis of gestational diabetes during COVID-19 pandemic: Position statement AMD-SID, diabetes, and pregnancy study group

Aim: In response to the COVID-19 pandemic, there is a need for substantial changes in the procedures for accessing healthcare services. Even in the current pandemic, we should not reduce our attention towards the diagnosis and treatment of GDM. The purpose of this document is to provide a temporary guide for GDM screening, replacing the current guidelines when it is not possible to implement standard GDM screening because of an unfavorable risk/benefit ratio for pregnant women or when usual laboratory facilities are not available. Data synthesis: At the first visit during pregnancy, we must exclude the presence of “Overt diabetes” in all women. The criteria for the diagnosis of overt diabetes are either fasting plasma glucose ≥126 mg/dL, or random plasma glucose ≥200 mg/dL, or glycated hemoglobin ≥6.5%. When the screening procedure (OGTT) cannot be safely performed, the diagnosis of GDM is acceptable if fasting plasma glucose is ≥ 92 mg/dL. In order to consider the impaired fasting glucose as an acceptable surrogate for the diagnosis of GDM, the fasting glucose measurement should be performed within the recommended time windows for the risk level (high or medium risk). Conclusions: The changes to the screening procedure for GDM reported below are specifically produced in response to the health emergency of the COVID-19 pandemic. Therefore, these recommended changes should cease to be in effect and should be replaced by current national guidelines when the healthcare authorities declare the end of this emergency.
