Addition of vitamin D reverses the decline in GFR following treatment with ACE inhibitors/angiotensin receptor blockers in patients with chronic kidney disease

Our data demonstrate reservation of estimated glomerular filtration with cholecalciferol supplementation to chronic kidney disease patients taking angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. The combination treatment of angiotensin converting enzyme inhibitors/angiotensin receptor blockers with cholecalciferol prevents the decline in estimated glomerular filtration in patients with chronic kidney disease following treatment with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and may represent a valid approach to reduce renal disease progression in chronic kidney disease patients with vitamin D deficiency. This result needs confirmation in prospective controlled clinical trials.
