Blood pressure behaviour in patients with malignant hypertension submitted to kidney transplantation.

The authors investigated post-renal transplantation hypertension behaviour in 20 patients with primary malignant hypertension (PMH), in 42 patients with secondary malignant hypertension (SMH) and in 62 controls (without malignant hypertension). All cases of malignant hypertension required removal of primary kidneys, either before or after transplantation. Hypertension was noticed at different periods of the post-renal transplantation phase, in 93% of PMH cases, 90% of SMH cases and in only 31% of the controls. After a period of time following transplantation, a decrease of hypertension incidence in the SMH and control groups was noticed, and persistence of hypertension was observed in the PMH group. The long-term development of PMH patients was worse than that of the other two groups.
