In conclusion, the results of the present study indicated that GLP‑1 may be a promising target for the development of novel therapeutic strategies for HG‑induced nephropathy, and may function through the activation of SIRT1.
The antihypertensive and renoprotective effects of GLP-1 receptor agonists are partly explained by their vasoactive effect and increased natriuresis, but their positive influences on blood pressure and the development and progression of kidney disease are attributed to many effects beyond glycemic control.
GLP-1 agonists did not affect the risk of MI (RR: 0.917; CI: 0.830-1.014; p = 0.092) as well as the risk of stroke (RR: 0.882; CI: 0.759-1.023; p = 0.097), HF (RR: 0.967; CI: 0.803-1.165; p = 0.725), retinopathy (RR: 1.000; CI: 0.807-1.238; p = 0.997) and nephropathy (RR: 0.866; CI: 0.625-1.199; p = 0.385).
GLP-1 plasma levels were determined in 3 different patient cohorts: 1) critically ill patients admitted to our intensive care unit (n = 215); 2) patients with chronic kidney disease on hemodialysis (n = 173); and 3) a control group (no kidney disease, no acute inflammation, n = 105).
These benefits may be consistent with the known effects of GLP-1 RA on traditional risk factors for progressive kidney disease including glucose lowering, blood pressure lowering, reduced insulin levels and weight reduction.
