- Design
- Single-centre two-arm randomised controlled trial
- Population
- 134 adults with type 2 diabetes at high risk of diabetic kidney disease
- Primary outcome
- HbA1c, UACR, eGFR, systolic BP, LDL-C, BMI and waist at 24 weeks
- Effect
- Significant improvement in HbA1c, eGFR, systolic BP and LDL-C; no change in UACR
A single-centre trial in Shandong, China, randomised 134 adults with type 2 diabetes identified as high risk for diabetic kidney disease by a validated prediction model. Half received a 12-week structured self-management programme, followed for a further 12 weeks; half received usual care.
At 24 weeks, the intervention group had significantly better HbA1c, eGFR, systolic blood pressure and LDL cholesterol. Urine albumin-to-creatinine ratio, BMI and waist circumference did not differ.
The abstract does not report effect sizes, the follow-up is short, and an eGFR change over 24 weeks may reflect haemodynamic factors rather than kidney protection. Self-management education complements, but cannot replace, the drugs that slow diabetic kidney disease.
- Offer structured self-management education to people with type 2 diabetes at risk of kidney disease
- Measure urine albumin-to-creatinine ratio and eGFR at least yearly
- Use an SGLT2 inhibitor and RAAS blockade where diabetic kidney disease is established, as guidelines advise
- Treat blood pressure and LDL cholesterol as part of kidney protection
Why it matters
It suggests risk factors can be improved before albuminuria appears, a stage when most patients receive little kidney-focused care.
Don't overread it
Effect sizes were not reported and albuminuria did not change, so kidney protection is not shown.
