PREVALENCE AND TIME OF DEVELOPMENT OF SYSTEMIC ARTERIAL HYPERTENSION IN PATIENTS AFTER LIVER TRANSPLANTATION

The use of immunosuppressive drugs after liver transplantation (LT) is associated with the development of systemic arterial hypertension (SAH), in addition to other comorbidities of metabolic syndrome.

Therefore, the purpose of this study was to analyze the time after use immunosuppressive drugs the patient progresses to SAH, as well as to identify its prevalence and the factors that may be correlated to it.

A retrospective and longitudinal study was conducted, based on the analysis of medical records of 72 normotensive patients, attended in the transplant unit of a university hospital, between 2016 and 2019.

It was observed, on average, 9±6.98 months after immunosuppressive use, the patients were diagnosed with hypertension, and the prevalence of transplanted patients who evolved to SAH in this study was 59.64% (41 patients). In addition, there was a correlation between serum dosage of tacrolimus and the development of SAH (P=0.0067), which shows that tacrolimus has a significant role in the development of SAH. Finally, it was noticed that the development of post-transplantation hypertension indicates a higher risk of the patient presenting the other parameters of metabolic syndrome, as well as a higher impairment in its renal function (P=0.0061).

This study shows that the patients evolved to SAH in an average of 9±6.98 months after immunosuppressive drug use. We have also found high prevalence of systemic arterial hypertension (59.64%) in patients after liver transplantation, who used calcineurin inhibitors, especially when associated with the use of tacrolimus.
