Assessing primary aldosteronism in diabetes patients at risk for kidney disease

Subclinical Primary Aldosteronism in Diabetes At-Risk for Kidney Disease

Early Phase 1 Interventional Brigham and Women's Hospital · NCT06190158

This study is testing how a hormone called aldosterone affects kidney health in people with type 2 diabetes who are at risk for kidney disease.

What this trial studies

This study aims to evaluate the presence and severity of primary aldosteronism in patients with type 2 diabetes who are at risk for chronic kidney disease (CKD). It focuses on understanding how this condition contributes to the progression of CKD and associated cardiovascular risks. Participants will undergo various suppression tests to assess aldosterone production and its effects on kidney health. The findings could lead to improved strategies for preventing CKD in high-risk diabetic patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-80 with type 2 diabetes who are at risk for developing chronic kidney disease.

Not a fit: Patients with type 1 or type 3 diabetes, or those with poorly controlled diabetes (HbA1c ≥ 9%) may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier identification and management of primary aldosteronism, potentially preventing or delaying chronic kidney disease in diabetic patients.

How similar studies have performed: Emerging evidence suggests that understanding primary aldosteronism in this context is a novel approach, with limited prior studies directly addressing this specific patient population.
