Compliance With Biochemical Objectives in Patients on Renal Replacement Therapy Before Kidney Transplantation in Mexico.

Objectives: The biochemical conditions in which patients arrive before renal transplantation (RT) are rarely evaluated; examples of them are found in the Dialysis Outcomes and Practice Patterns Study (DOPPS). The objective of our study was to ascertain the fulfillment of biochemical goals for patients on renal replacement therapy before RT.

Material And Methods: Observational, retrospective study of patients who were on a RT protocol between 2012 and 2017 in 2 RT centers in Mexico. The records of 1188 patients with a history of RT and their lab results before transplantation were analyzed. Anthropometric values including hemoglobin, iron levels, calcium, phosphorus, parathyroid hormone, urea, creatinine, uric acid, and left ventricular ejection fraction were studied. All values were categorized as low, optimal, or high levels.

Results: The fulfillment of pretransplant biochemical objectives for elimination of azotemia (urea and creatinine) was achieved in 60% of the patients. Optimal values for calcium were found in 715 (64%) patients and optimal values for albumin were found in 690 (61.8%) patients. In the case of phosphorus, hemoglobin, uric acid, and parathyroid hormone, the optimal values were below 50%.

Conclusions: It is essential to improve compliance with biochemical and clinical objectives for patients on renal replacement therapy (dialysis, hemodialysis) before RT. Only half of the variables were within the optimal range before surgical intervention took place.
