Abstract

Case 1 was a 33-year-old male with type 1 diabetes since age 6 years and hypothyroidism due to Hashimoto’s thyroiditis; the patient missed annual labs for 2 years. He used continuous subcutaneous insulin infusion (CSII) and had achieved an HbA1c level of <7% for several years. Case 2 was a 38-year-old male with type 1 diabetes, hypertension, hyperlipidemia, and selective IgM deficiency who had significant albuminuria on routine screening. Type 1 diabetes was diagnosed at age 12 years and was well controlled with HbA1c levels ranging from 6–7.5%.
