Ps-C26-5: Renal Artery Remodeling and Renal Renin Angiotensin System in Chronic Kidney Disease

Abstract

Background: Hypertensive emergencies are poor prognosis conditions associated with rapid blood pressure (BP) elevation and various organ damage. The frequency of dialysis induction due to nephrosclerosis is high and early detection and appropriate therapeutic intervention are important. Methods:We selected 15 patients diagnosed as hypertensive emergencies with severe renal dysfunction (serum creatinine level > 2.5 mg/dL) admitted to our hospital between 2005 and 2019. These were divided into two groups: those who received a renal replacement therapy (RRT) after 3 years and those who were not received (non-RRT). The clinical features and laboratory data between the two groups were reviewed and compared retrospectively. Results:The median age was 48 years old and the male to female ratio was 3:1. All the patients lacked medical examination and regular checkups after diagnosis of hypertension. 33% of them were obese with body mass index > 25. Six patients resulted in end-stage renal disease and received RRT. On admission, about 80% had elevated plasma renin activity and serum aldosterone levels, while there were no cases of renal artery stenosis. Between two groups, there was no significant difference in serum creatinine levels. Serum LDH levels in the non-RRT group were higher than those in the RRT group. Serum potassium levels and platelet counts were lower, respectively. These data at post-antihypertensive treatment was improved significantly in the non-RRT group. Serum values of LDH, potassium, and platelet in the comparison of pre-and post-treatment data of the two groups showed significantly improved by two-way analysis of variance.
