Prevalence and Risk Factors of Noncontrolled and Resistant Arterial Hypertension in Renal Transplant Recipients

Abstract : BACKGROUND: Arterial hypertension (HT) is common in renal transplant recipients (RTRs). Control of HT is not optimal in this high-risk population despite recommendations for target blood pressure levels under 130/80 mm Hg. METHODS: We performed a cross-sectional analysis of the prevalence of uncontrolled HT, and using a Cox regression model, we identified the risk factors associated with resistant HT. RESULTS: Eight hundred eleven RTRs (>1 year after transplantation) were included. A total of 10.5% were normotensive (<130/80 mm Hg without treatment), 41% had controlled HT, 32.5% uncontrolled HT, and 16% resistant HT. In univariate analysis, compared to controlled HT, the RH group had significantly higher body mass index and older donors, delayed graft function, prevalence of metabolic syndrome (69.2 vs. 51.9%), fast glycemia and glycated hemoglobin, albuminuria, triglycerides and uric acid levels, and worse measured glomerular filtration rate (mGFR). In multivariate analysis, recipient age (P < 0,001), mGFR (P = 0.037), albuminuria (P < 0.001), and metabolic syndrome (P = 0.007) were significantly associated with RH. Association of metabolic syndrome with RH was much stronger than each of its components. CONCLUSION: Our data show that despite the recommendations issued by scientific societies, blood pressure control in RTRs is far from the recommended targets. At least a third of our patients (uncontrolled HT) did not receive optimal treatment and suffered therapeutic inertia. Decreased mGFR, metabolic syndrome, and urinary albumin excretion emerged as strong predictors of poor HT control. Whether prevention and management of the metabolic syndrome and reduction of albuminuria could help to more consistently reach the blood pressure recommended targets deserves further investigation.
