High peritoneal transport: a blessing or curse?

Adv Perit Dial. 2002;18:106-11.

Abstract

High transporters are defined based on the peritoneal equilibration test. Peritoneal transport rate changes over time, inflammation and angiogenesis affecting the total pore area. Factors influencing the neovascularization process are described. High transporters have distinctive clinical and laboratory features. The incidence of high transporters varies among different populations. Unfortunately, high transporters have the worst clinical outcomes. Mechanisms proposed to explain the adverse prognosis--including hypoalbuminemia, chronic fluid overload, malnutrition, and chronic inflammation--are discussed. We suggest dividing baseline high transporters into two groups: "sick" and "healthy" high transporters. The two types of high transporters have different baseline characteristics and different clinical outcomes. Hopefully, further studies will better define the appearance of the two groups of high transporters.
