Tactics to prevent or slow progression of CKD in patients with diabetes

Dyslipidemia and DKD

Because the risk of CVD is increased in patients with DKD, addressing other modifiable risk factors, including dyslipidemia, is recommended in these patients. Patients with diabetes and stages 1 to 4 DKD should be treated with a high-intensity statin or a combination of a statin and ezetimibe.^49,50

Tight glycemic control in T1D and T2D can delay the onset, and slow the progression, of albuminuria and a decline in the eGFR.

If a patient is taking a statin and starting dialysis, it’s important to discuss with him or her whether to continue the statin, based on perceived benefits and risks. It is not recommended that statins be initiated in patients on dialysis unless there is a specific cardiovascular indication for doing so. Risk reduction with a statin has been shown to be significantly less in dialysis patients than in patients who are not being treated with dialysis.⁴⁹

Complications of CKD

Anemia is a common complication of CKD. KDIGO recommends measuring the ­hemoglobin concentration annually in DKD stage 3 patients without anemia; at least every 6 months in stage 4 patients; and at least every 3 months in stage 5. DKD patients with anemia should have additional laboratory testing: the absolute reticulocyte count, serum ferritin, serum transferrin saturation, vitamin B12, and folate.⁵¹

Mineral and bone disorder should be screened for in patients with DKD. TABLE 2⁵² outlines when clinical laboratory tests should be ordered to assess for mineral bone disease.

When to refer to a nephrologist

Refer patients with stage 4 or 5 CKD (eGFR, ≤ 30 mL/min/1.73 m²) to a nephrologist for discussion of kidney replacement therapy.⁶ Patients with stage 3a CKD and severely increased albuminuria or with stage 3b CKD and moderately or severely increased albuminuria should also be referred to a nephrologist for intervention to delay disease progression.
