Achieving glycemic control in type 2 diabetes: a practical guide for clinicians on oral hypoglycemics.

Type 2 diabetes mellitus has reached epidemic proportions in the United States. Cardiovascular morbidity and mortality are particularly high in this patient population. Improved glucose control, especially early in the course of diabetes, can slow or prevent complications, preserve beta-cell function, and improve long-term outcomes.

Artificially low hemoglobin A1c caused by use of dapsone.

Objective: To describe a case of artifactually decreased hemoglobin Alc (HbAlc) attributable to use of dapsone.

Methods: We present a detailed case report and results of a related literature search. In addition, potential causes of artifactually lowered HbAlc values are discussed.
