Abstract

Hypothesis/objectives: Early prevention of diabetic nephropathy by way of blocking the renin-angiotensin system (RAS) in patients with normoalbuminuria seems rational, but trials have so far shown conflicting results. The present meta-analysis was undertaken to investigate if such treatment can prevent development of microalbuminuria. Materials and methods: We searched MEDLINE, EMBASE and the Cochrane Library (2 June 2014) for randomised controlled trials, with a population of patients with type 2 diabetes and normoalbuminuria, comparing angiotensin-converting enzyme inhibitors (ACEis) or angiotensin receptor blockers (ARBs) to placebo. Studies had to have at least 50 participants in each arm and one year of follow-up. Random and fixed effect models were performed as well as trial sequential analysis. Results: Six trials were included in the analysis ( n=16,921). Overall risk of bias was variable. In a fixed model analysis ACE or ARB treatment was superior to placebo in relation to prevention of development of microalbuminuria, risk ratio 0.84 (95% confidence interval (CI) 0.79–0.88) p<0.001, I 2 =23%, similar to random model results. Treatment also showed a trend towards a reduction in all-cause mortality( p=0.07). Conclusions: We conclude that in patients with type 2 diabetes and normoalbuminuria, early intervention with ACEis or ARBs reduces the risk for development of microalbuminuria.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Available data suggest that ACEi and ARB treatments are not beneficial for patients with neither albuminuria nor elevated blood pressure.

    “Available data suggest that ACEi and ARB treatments are not bene fi cial for patients with neither albuminuria nor elevated blood pressure.”

    From KDIGO 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease (2022) · cites this paper as [60]

    The Discussion reports that ACEi/ARB treatment reduced microalbuminuria in normoalbuminuric patients with type 2 diabetes. It says the authors could not analyze normotensive patients separately and could not rule out a similar benefit in them. The paper therefore does not suggest that treatment is unbeneficial for patients without albuminuria or elevated blood pressure. (LLM, conf=0.85)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • A review found 6 studies in normoalbuminuric T2D patients showing benefit on albuminuria progression by RAS blockade, but most patients had hypertension.

    “A review found 6 studies in normoalbuminuric T2D patients showing bene fi t on albuminuria progression by RAS blockade, but most patients had hypertension. 60”
  • There is clinical inertia in treating residual hypertension among people with type 2 diabetes.

    “There appears to be inertia to treat residual hypertension in persons with T2D, and pharmacotherapy should be intensified when needed to achieve BP goals.”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [251]

    The Discussion recommends considering ACE inhibitors or ARBs for people with type 2 diabetes, including for hypertension, but does not assess whether clinicians fail to treat residual hypertension. The Results report baseline hypertension status, not treatment inertia. Searches for clinical inertia, residual hypertension, and treatment intensification found no passage addressing that claim.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
