Secondary Hypertension

Definition and Prevalence of Secondary Hypertension Secondary hypertension is generally defined as hypertension associated with a specific cause and, therefore, potentially curable if that cause is removed. The use of this definition generates two separate lines of diseases. The first…

Evaluation and Management of Hypertension

## Hypertension remains the leading cause of cardiovascular (CV) mortality and morbidity including stroke, heart disease, kidney disease, and other vascular disease. The relationship between blood pressure (BP) and CV risk is linear, continuous, and additive to other well-known risk…

Pathogenesis of Hypertension

Hypertension implies an increase in either cardiac output or, more typically, in systemic vascular resistance (SVR). Essential hypertension developing in young adults may be initiated by an increase in cardiac output, associated with signs of overactivity of the sympathetic nervous…

Infectious Complications of Kidney Transplantation

Infections are among the more common complications following kidney transplantation. While advances in surgical techniques and modern induction and maintenance immunosuppression regimens have improved the outcomes of the allograft, they have also changed the risk of posttransplant infections over time.…

Immunosuppression in Transplantation

The central issue in organ transplantation remains the prevention of allograft rejection. Understanding the physiology of the immune response to a transplanted organ, developing targeted immunosuppressive drugs, and devising the best combinations to maintain safety and improve efficacy are key…

Posttransplantation Monitoring and Outcomes

Introduction Kidney transplantation is the kidney replacement modality of choice for most patients with end-stage kidney disease (ESKD). Evidence shows that most kidney transplant recipients (KTRs) experience a higher quality of life and improved long-term survival compared to wait-listed patients…

Conservative Kidney Management

Introduction Dialysis extends and improves the lives of many patients with advanced kidney disease. It frequently serves as an effective bridge to kidney transplantation. However, for some patients, dialysis does not add meaningful time and negatively impacts quality of life.…

Peritoneal Dialysis

Introduction In peritoneal dialysis (PD), a chronically indwelling catheter is placed into the peritoneal space. A peritoneum enriched in a vascular capillary network is the dialysis membrane. Introduction of dialysis fluid into the peritoneum (glucose [or dextrose monohydrate] based) creates…

Hemodialysis and Hemofiltration

## Hemodialysis (HD) is an extracorporeal therapy that is prescribed to reduce the signs and symptoms of uremia and to partially replace a number of the key functions of the kidneys when kidney function is no longer sufficient to maintain…
