What HbA1c target is recommended for diabetic patients with CKD?

• A. <7.0
• B. <6.5
• C. <7.5
• D. <6.0

Answer: (B)

Lowering HbA1c to a level under 6.5% is chosen when managing diabetes in the setting of chronic kidney disease because tighter glycemic control can reduce microvascular complications and slow the progression of nephropathy, provided the patient can avoid hypoglycemia. HbA1c reflects average glucose over about three months, so keeping it under 6.5% helps limit sustained hyperglycemia that damages the kidneys and vessels. However, CKD itself raises the risk of hypoglycemia due to altered insulin clearance and reduced gluconeogenesis, and anemia or erythropoietin use can make HbA1c readings less reliable. Therefore, the target should be individualized: in patients with a higher risk of hypoglycemia or advanced CKD, a less strict goal (such as under 7%) may be appropriate, while in those with low hypoglycemia risk and good overall health, aiming for under 6.5% can be beneficial.
