- 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 randomised trial in Shandong, China, enrolled 134 adults with type 2 diabetes classed as high risk for diabetic kidney disease by a validated prediction model. Half received a 12-week structured self-management programme followed by 12 weeks of follow-up; half received usual care.
The intervention group showed significant improvements in HbA1c, eGFR, systolic blood pressure and LDL cholesterol. Albuminuria, BMI and waist circumference did not change significantly. Attrition was modest and sensitivity analyses agreed.
The abstract does not give the size of the differences, the trial ran for only 24 weeks, and it measured risk factors rather than kidney outcomes. It adds modestly to the case for structured education, which most guidelines already support.
- Offer structured diabetes self-management education, especially to patients at risk of kidney disease
- Check urine albumin-to-creatinine ratio and eGFR at least yearly in type 2 diabetes
- Treat blood pressure and LDL cholesterol as part of kidney protection, not only heart protection
- Consider an SGLT2 inhibitor once chronic kidney disease is established, as guidelines advise
Why it matters
It suggests risk factors can be moved early, before albuminuria appears, with education rather than another drug.
Don't overread it
Effect sizes were not reported in the abstract, and albuminuria did not change, so kidney benefit is unproven.
