Hypertension after kidney transplantation: impact, pathogenesis and therapy

Abstract

Hypertension (HTN) contributes to the high incidence of cardiovascular disease mortality as well as chronic allograft nephropathy (CAN) and late graft failure in renal transplant recipients. The mechanisms are complex and may involve pathogenic factors attributable to the host, allograft, and immunosuppressive drugs. Calcium channel blockers should be used to ameliorate the nephrotoxicity of calcineurin inhibitors in the early years after transplantation. Angiotensin-converting enzyme inhibitors and angiotensin-2 type-1 receptor blockers are safe and effective, have antiproteinuric effects, slow the progression of CAN, and may provide survival benefits. Diuretics and/or beta-adrenergic receptor blockers are frequently added in combination regimen. Appropriate adjustment of the immunosuppressive drugs should also be considered for the long-term care of kidney recipients with HTN.
