Systematic Review of Treatment of Beta-Cell Monogenic Diabetes.

There is limited evidence to guide the treatment in monogenic diabetes with most studies being non-randomized and small. The combined data does support: no treatment being needed in GCK-related hyperglycemia; SU being used as the first line treatment in HNF1A-diabetes; SU can be tried in HNF4A- diabetes; insulin often needed in HNF1B-diabetes and MD with the m.3243A>G variant; SU can be tried in 6q24-TND relapse; and thiamine may improve glycemic control in SLC19A2-diabetes. Further evidence, particularly randomized comparative studies, are needed to examine the optimum treatment for glycemic response in all monogenic subtypes.
