NCT06533618

Brief Summary

Dysglycemia is a frequent finding in transfusion-dependent thalassemia (TDT). The oral glucose tolerance test (OGTT) remains the only validated screening test, but the procedure is complex and time-consuming. Continuous glucose monitoring (CGM) systems are simple to use, and could have a role in the diabetes mellitus diagnosis. This study involved 39 participants (19 cases and 20 healthy controls) using CGM for the analysis of the glucose metrics. Participants resulted negative for diabetes mellitus screening tests. Patients' clinical data were compared with glucose metrics.
