Abstract

Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) are well-established glucose-lowering drugs for type 2 diabetes mellitus (T2DM) management. Acute GLP-1RA administration increases urinary excretion of sodium and other electrolytes. However, the renal tubular effects of prolonged GLP-1RA treatment are largely unknown. In this secondary analysis of a randomized trial, we determined the renal tubular effects of 8-wk treatment with 20 μg lixisenatide, a short-acting (prandial) GLP-1RA, versus titrated once-daily insulin glulisine in 35 overweight T2DM-patients on stable insulin glargine background therapy (age: 62 ± 7 yr, glycated hemoglobin: 8.0 ± 0.9%, estimated glomerular filtration rate: >60 ml·min−1·1.73 m−2). After a standardized breakfast, lixisenatide increased absolute and fractional excretions of sodium, chloride, and potassium and increased urinary pH. In contrast, lixisenatide reduced absolute and fractional excretions of magnesium, calcium, and phosphate. At week 8, patients treated with lixisenatide had significantly more phosphorylated sodium-hydrogen exchanger isoform 3 (NHE3) in urinary extracellular vesicles than those on insulin glulisine treatment, which suggested decreased NHE3 activity in the proximal tubule. A rise in postprandial blood pressure with lixisenatide partly explained the changes in the urinary excretion of sodium, potassium, magnesium, and phosphate and the changes in urinary pH. In conclusion, lixisenatide affects postprandial urinary excretion of several electrolytes and increases urinary pH compared with insulin glulisine in T2DM patients after 8 wk of treatment. This is most likely explained by a drug-induced rise in blood pressure or direct inhibitory effects on NHE3 in the proximal tubule.

  • GLP-1 receptor activation can induce a proximal tubular natriuresis via inhibition of sodium-hydrogen exchanger 3, an effect proposed to activate tubuloglomerular feedback which may reduce glomerular hyperfiltration and GFR.

    “Furthermore, GLP-1 receptor activation can induce a proximal tubular natriuresis via inhibition of sodium-hydrogen exchanger 3, an effect proposed to activate tubuloglomerular feedback which may reduce glomerular hyperfiltration and GFR.29”

    From The Effect of Retatrutide on Kidney Parameters in Participants With Type 2 Diabetes Mellitus and/or Obesity (2025) · cites this paper as [29]

    The Introduction reports that rodent studies suggest GLP-1 receptor stimulation inhibits proximal-tubule NHE3, and the Discussion links lixisenatide-associated sodium excretion to possible NHE3 inhibition. The passages found do not propose the further step of tubuloglomerular-feedback activation or a consequent reduction in hyperfiltration or GFR; searches for those terms found no supporting passage.

  • In both rodents and humans, GLP-1 receptor agonist infusion enhances kidney lithium clearance, a marker of proximal tubular sodium reabsorption, as well as urinary pH.

    “in both rodents and humans, GLP-1 receptor agonist infusion enhances kidney lithium clearance, a marker of proximal tubular sodium reabsorption, as well as urinary pH.”

    From GLP-1 agonists in the treatment of chronic kidney disease in type 2 diabetes and obesity (2025) · cites this paper as [33]

    The Discussion reports that acute GLP-1 receptor stimulation increases urinary lithium excretion in rodents and humans, and that GLP-1 or exenatide infusion increases urinary pH in people. It does not establish that infusion was the method in the rodent lithium studies or that urinary pH increased in rodents. Page numbers are unavailable in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The effect of GLP-1 receptor agonists on natriuresis involves inhibition of sodium-hydrogen antiporter NHE3.

    “This suggests that the effect involves inhibition of sodium-hydrogen antiporter (NHE3) (33).”

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.
