Criteria for assessing renal allograft dysfunction

The significance of the glomerular filtration rate calculated by the Cockcroft - Gault formula as one of the highly sensitive criteria for assessing renal allograft dysfunction is substantiated. The study demonstrated that in the group of patients with an increased level of daily proteinuria there is a significantly lower level of serum creatine in comparison with the group of patients with a normal level of daily proteinuria. Moreover, in patients with a normal level of daily proteinuria, there are significantly higher values of glomerular filtration rate calculated by the Cockcroft - Gault formula, compared with patients with an increased level of daily proteinuria. Thus, it is shown that the level of serum creatinine currently used in clinical practice, as a laboratory marker of renal allograft dysfunction, does not allow to detect impaired renal allograft function at the earliest possible date. It has been demonstrated that the glomerular filtration rate calculated by the Cockcroft - Gault formula is a highly sensitive and specific laboratory marker of renal transplant dysfunction. Determining the glomerular filtration rate calculated by the Cockcroft - Gault formula makes it possible to diagnose renal allograft dysfunction at the earliest stages, which will significantly improve the survival of the transplanted kidney due to timely changes in patient management tactics and correction of immunosuppressive therapy.
