Cognitive Function and Kidney Disease: Baseline Data From the Systolic Blood Pressure Intervention Trial (SPRINT).

ABSTRACT: BACKGROUND:Chronic kidney disease is common and is associated with cardiovascular disease, cerebrovascular disease, and cognitive function, although the nature of this relationship remains uncertain. STUDY DESIGN:Cross-sectional cohort using baseline data from the Systolic Blood Pressure Intervention Trial (SPRINT). SETTING & PARTICIPANTS:Participants in SPRINT, a randomized clinical trial of blood pressure targets in older community-dwelling adults with cardiovascular disease, chronic kidney disease, or high cardiovascular disease risk and without diabetes or known stroke, who underwent detailed neurocognitive testing in the cognition substudy, SPRINT-Memory and Cognition in Decreased Hypertension (SPRINT-MIND). PREDICTORS:Urine albumin-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR). OUTCOMES:Cognitive function, a priori defined as 5 cognitive domains based on 11 cognitive tests using z scores, and abnormal white matter volume quantified by brain magnetic resonance imaging. RESULTS:Of 9,361 SPRINT participants, 2,800 participated in SPRINT-MIND and 2,707 had complete data; 637 had brain imaging. Mean age was 68 years, 37% were women, 30% were black, and 20% had known cardiovascular disease. Mean eGFR was 70.8±20.9mL/min/1.73m2 and median urine ACR was 9.7 (IQR, 5.7-22.5) mg/g. In adjusted analyses, higher ACR was associated with worse global cognitive function, executive function, memory, and attention, such that each doubling of urine ACR had the same association with cognitive performance as being 7, 10, 6, and 14 months older, respectively. Lower eGFR was independently associated with worse global cognitive function and memory. In adjusted models, higher ACR, but not eGFR, was associated with larger abnormal white matter volume. LIMITATIONS:Cross-sectional only, no patients with diabetes were included. CONCLUSIONS:In older adults, higher urine ACR and lower eGFR have independent associations with global cognitive performance with different affected domains. Albuminuria concurrently identifies a higher burden of abnormal brain white matter disease, suggesting that vascular disease may mediate these relationships.

Project description:INTRODUCTION:Erectile function, an important aspect of quality of life, is gaining increased research and clinical attention in older men with hypertension. AIM:To assess the cross-sectional association between blood pressure measures (systolic blood pressure [SBP]; diastolic blood pressure [DBP]; and pulse pressure [PP]) and (i) sexual activity and (ii) erectile function in hypertensive men. METHODS:We performed analyses of 1,255 male participants in a larger randomized clinical trial of 9,361 men and women with hypertension aged ?50 years. MAIN OUTCOME MEASURES:The main outcome measures were self-reported sexual activity (yes/no) and erectile function using the 5-item International Index of Erectile Function (IIEF-5). RESULTS:857 participants (68.3%) reported being sexually active during the previous 4 weeks. The mean (SD) IIEF-5 score for sexually active participants was 18.0 (5.8), and 59.9% of the sample reported an IIEF-5 score <21, suggesting erectile dysfunction (ED). In adjusted logistic regression models, neither SBP (adjusted odds ratio = 0.998; P = .707) nor DBP (adjusted odds ratio = 1.001; P = .929) was significantly associated with sexual activity. In multivariable linear regression analyses in sexually active participants, lower SBP (? = -0.04; P = .025) and higher DBP (? = 0.05; P = .029) were associated with better erectile function. In additional multivariable analyses, lower PP pressure was associated with better erectile function (? = -0.04; P = .02). CLINICAL IMPLICATIONS:Blood pressure is an important consideration in the assessment of erectile function in men with hypertension. STRENGTHS & LIMITATIONS:Assessments of blood pressure and clinical and psychosocial variables were performed using rigorous methods in this multi-ethnic and geographically diverse sample. However, these cross-sectional analyses did not include assessment of androgen or testosterone levels. CONCLUSIONS:Erectile dysfunction was highly prevalent in this sample of men with hypertension, and SBP, DBP, and PP were associated with erectile function in this sample.

Project description:INTRODUCTION:Sexual function, an important component of quality of life, is gaining increased research and clinical attention in older women with hypertension. AIM:To assess the association between systolic blood pressure (SBP) and other variables, and sexual activity and sexual dysfunction in hypertensive women. METHODS:Baseline analysis of 635 women participants of a larger randomized clinical trial of 9361 men and women. MAIN OUTCOME MEASURES:Self-reported sexual activity (yes/no), and sexual function using the Female Sexual Function Inventory (FSFI). RESULTS:452 participants (71.2%) reported having no sexual activity during the previous 4 weeks. The mean (SD) FSFI score for sexually active participants was 25.3 (6.0), and 52.6% of the sample reported a FSFI score ?26.55 designating sexual dysfunction. In logistic regression models, SBP was not significantly associated with sexual activity (AOR = 1.002; P > .05). Older age (AOR = 0.95, P < .05), and lower education (AOR for < high school vs college degree = 0.29, P < .05) were associated with lower odds of being sexually active, as was living alone versus living with others (AOR = 0.56, P < .05). Higher weekly alcohol consumption was associated with increased odds of being sexually active (AOR = 1.39; P < .05). In logistic regression models among sexually active participants, SBP was not associated with sexual dysfunction (AOR = 1.01; P > .05). Higher depressive symptoms from the Patient Health Questionnaire-9 (PHQ-9) was associated with higher odds of sexual dysfunction (AOR = 1.24, P < .05), as was increased number of physical comorbidities (AOR = 1.25, P < .05). Diuretic use was associated with lower odds of being sexually active in participants with chronic kidney disease (AOR = 0.33, P < .05). CONCLUSION:Younger age, higher education, living with others, and higher weekly alcohol consumption were significantly associated with higher odds of being sexually active in a sample of middle-aged and older women with hypertension. Increased depressive symptoms and increased physical comorbidities were significantly associated with increased odds of sexual dysfunction. SBP was not significantly associated with sexual activity or sexual dysfunction.

Project description:BACKGROUND:Treating to a lower blood pressure (BP) may increase acute kidney injury (AKI) events. STUDY DESIGN:Data for AKI resulting in or during hospitalization or emergency department visits were collected as part of the serious adverse events reporting process of the Systolic Blood Pressure Intervention Trial (SPRINT). SETTING & PARTICIPANTS:9,361 participants 50 years or older with 1 or more risk factors for cardiovascular disease. INTERVENTIONS:Participants were randomly assigned to a systolic BP target of <120 (intensive arm) or <140mmHg (standard arm). OUTCOMES & MEASUREMENTS:Primary outcome was the number of adjudicated AKI events. Secondary outcomes included severity of AKI and degree of recovery of kidney function after an AKI event. Baseline creatinine concentration was defined as the most recent SPRINT outpatient creatinine value before the date of the AKI event. RESULTS:There were 179 participants with AKI events in the intensive arm and 109 in the standard arm (3.8% vs 2.3%; HR, 1.64; 95% CI, 1.30-2.10; P<0.001). Of 288 participants with an AKI event, 248 (86.1%) had a single AKI event during the trial. Based on modified KDIGO (Kidney Disease: Improving Global Outcomes) criteria for severity of AKI, the number of AKI events in the intensive versus standard arm by KDIGO stage was 128 (58.5%) versus 81 (62.8%) for AKI stage 1, 42 (19.2%) versus 18 (14.0%) for AKI stage 2, and 42 (19.2%) versus 25 (19.4%) for AKI stage 3 (P=0.5). For participants with sufficient data, complete or partial resolution of AKI was seen for 169 (90.4%) and 9 (4.8%) of 187 AKI events in the intensive arm and 86 (86.9%) and 4 (4.0%) of 99 AKI events in the standard arm, respectively. LIMITATIONS:Trial results are not generalizable to patients with diabetes mellitus or without risk factors for cardiovascular disease. CONCLUSIONS:More intensive BP lowering resulted in more frequent episodes of AKI. Most cases were mild and most participants had complete recovery of kidney function. TRIAL REGISTRATION:Registered at ClinicalTrials.gov with study number NCT01206062.
