A Swedish analysis has identified 5 diabetic "clusters" that could aid diagnosis and individualize treatment. Scroll through our quick slideshow for details.
A novel anlaysis from Sweden redefines how traditional type 1 and type 2 diabetes are viewed. The investigators stratified a total of 8980 patients with newly diagnosed diabetes into 5 “clusters” based on risk of specific diabetic complications. The purpose of the reclassification was to identify diabetic subtypes that could better drive diagnosis and customized therapies to prevent complications.

Cluster 1: Severe Autoimmune Diabetes (SAID). Characterized by early-onset diabetes, relatively low BMI, poor metabolic control, insulin deficiency, and GADA positive. Patients with SAID have a high risk of ketoacidosis.
Cluster 2: Severe Insulin-Deficient Diabetes (SIDD). Characterized by young age at onset, relatively low BMI, poor metabolic control, low insulin secretion (HOMA2-B index), and GADA positive. Patients with SIDD have a high risk of diabetic retinopathy and ketoacidosis.
Cluster 3: Severe Insulin-Resistant Diabetes (SIRD). Characterized by insulin resistance (high HOMA2-IR index) and high BMI. Patients with SIRD have a high risk of diabetic kidney disease and non-alcoholic fatty liver disease.
Cluster 4: Mild Obesity-Related Diabetes (MOD). Characterized by very high BMI (obesity) and no insulin resistance.
Cluster 5: Mild Age-Related Diabetes (MARD). Characterized by older patients vs other clusters and minimal metabolic disorder.
