ABSTRACT
Introduction: The mortality rate in diabetic dialysis patients (DDPs) is over 15% per year, with the cause of death most often attributed to cardiovascular disease (CVD) or bacterial infection (sepsis). Identification of genetic markers predictive of early mortality would be useful in the evaluation of therapies for the reduction of mortality rate in this population. Haptoglobin (Hp) is a polymorphic protein which appears to confer differential susceptibility to bacterial infection and CVD. We therefore proposed that Hp phenotype can predict mortality in DDPs. Methods: We tested this hypothesis prospectively in a longitudinal study of 392 dialysis patients from eight medical centres in Israel. Hp was determined by polyacrylamide gel electrophoresis. Patients were followed for all-cause mortality over a 3-year period. Results: We found that Hp phenotype was a significant predictor of mortality in DDPs stratified by age. In diabetic individuals over 60 years of age there was a decrease in mortality associated with the Hp 1-1 phenotype (P = 0.03). However, in younger DDPs the Hp 2-2 phenotype was associated with a decreased mortality rate (P = 0.003). Conclusion: Hp phenotype may be useful in the risk stratification algorithm and management of DDPs.

    Background: Haptoglobin (Hp) is a plasma protein with antioxidant and immunomodulatory properties. Three main genotypes/phenotypes (Hpl -1, Hp2-1, Hp2-2) show distinctive efficiencies in their activities and have been related to susceptibility and outcome in different diseases, including HIV...
