Antihypertensives associated with lower dialysis risk for patients with advanced CKD

Summary:
Patients with stable hypertension and the most advanced stage of chronic kidney disease before dialysis appeared to have a lower risk for long-term dialysis or death if they were treated with the antihypertensive drugs known as angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, according to a study published.

Patients with stable hypertension and the most advanced stage of chronic kidney disease (CKD) before dialysis appeared to have a lower risk for long-term dialysis or death if they were treated with the antihypertensive drugs known as angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs), according to a study published by JAMA Internal Medicine, a JAMA Network publication.

An ACEI or ARB is known to delay the progression of CKD in patients with and without diabetes, particularly in those patients with mild to moderate renal insufficiency. But most large clinical trials of ACEI/ARB exclude patients with the most advanced stage of CKD predialysis, perhaps out of concern that the drugs can cause renal failure and the need for dialysis, so it remains unclear whether that therapy is effective in patients with advanced CKD, according to the study background.

Researchers in Taiwan examined the association between ACEI/ARB use and the risk of long-term dialysis and death in a nationwide group of 28,497 patients in a study by Ta-Wei Hsu, M.D., of the National Yang-Ming University Hospital, and colleagues. The patients had the most advanced predialysis stage of CKD, hypertension and anemia.

During a median follow-up of seven months, 20,152 patients (70.7 percent) required long-term dialysis and 5,696 (20 percent) died before progressing to ESRD (end-stage renal disease). Study findings indicate that treatment with ACEIs/ARBs in patients with stable hypertension and advanced CKD was associated with a lower risk for long-term dialysis or death by 6 percent.

"In conclusion, our findings expand the existing knowledge in the field and provide clinicians with new information," the authors conclude.
