BACKGROUND AND OBJECTIVES:The overall prevalence of essential hypertension in adolescents may be growing. Differences in blood pressure (BP) are well established in adults, but are less clear in adolescents. We hypothesize that the prevalence of hypertension differs by race/ethnicity among adolescents at school-based screenings.

SummaryBackground and objectives Although Henoch-Schö nlein purpura (HSP) is the most common form of renal vasculitis in childhood, progression to ESRD is rare, and there are few data on outcomes of renal transplantation in patients with HSP.Design, setting, participants, & measurements This is a matched retrospective cohort study of renal allografts using the United Network of Organ Sharing database (1987 to 2005). Of the 189,211 primary renal allografts, there were 339 with a diagnosis of HSP. The primary end point was allograft survival. ResultsCompared with the remainder of the database, the HSP population was younger (25 years versus 46 years), and had a higher proportion of women (47% versus 40%), live donors (50% versus 35%), and Caucasians (77% versus 60%). Controlling for age, gender, donor source, ethnicity, and year of transplantation, death-censored graft survival for patients with HSP was 80.0% at 5 years and 58.8% at 10 years compared with 79.0% at 5 years and 55.4% at 10 years in the non-HSP population. Among patients with reported causes of graft loss, failure from recurrent disease occurred in 13.6% of patients with HSP, compared with 6.6% in the non-HSP population. When analyzing allograft survival in recipients with HSP compared with those with IgA nephropathy, there was no difference in 10-year allograft survival (58.4% and 59.3%, respectively). ConclusionsThese data indicate that although there is an increased risk of graft failure attributable to recurrent disease in patients with HSP, a diagnosis of HSP has little effect on overall renal allograft survival.

Weekly docetaxel is associated with less neutropenia and a trend toward improved survival in elderly or PS 2 patients. PS rather than age is the primary determinant of outcome in this population. Octogenarians benefited from weekly docetaxel. Future studies should separate elderly patients from PS 2 patients.

Hypertension in children and adolescents is becoming a greater problem in the developed world. Although traditionally thought of as usually secondary to renal, vascular, or endocrine causes, primary hypertension is becoming the most common form seen in childhood. This changing epidemiology is related to the recent obesity epidemic. The evaluation of high blood pressure in children is more involved than in adults and is aimed both at identifying secondary causes and to identify other co-morbidities of cardiovascular risk. Treatment of hypertension in childhood and adolescence is aimed at reducing cardiovascular risk. While there are a growing number of antihypertensive agents with FDA labeling for children, there remain far fewer options than for adults. This paper reviews the epidemiology, definitions, evaluations, and management of elevated blood pressure in children and adolescents.

OBJECTIVES: Clinicians prescribe antihypertensive medication to children with primary hypertension, but without data to define a particular choice as first-line therapy. A one-sizefits-all approach may not be appropriate for these patients. Our aim was to develop a personalized approach to hypertension treatment, using repeated ambulatory blood pressure monitoring (ABPM) in n-of-1 trials (single-patient randomized crossover trials).METHODS: Children undergoing hypertension management at a single pediatric referral center were offered participation in an n-of-1 trial with repeated ABPM to compare 3 commonly used medications. The medication producing the greatest blood pressure reduction, and without unacceptable side effects, was selected as the preferred therapy for the individual.RESULTS: Forty-two children agreed to participate; 7 were normotensive without medication; and 3 failed to complete one treatment cycle. Of the remaining 32 patients, lisinopril was preferred for 16, amlodipine for 8, hydrochlorothiazide for 4, and 4 had uncontrolled blood pressure on maximum doses of monotherapy. In conservative Bayesian analyses, the proportion of patients who preferred lisinopril was 49% (95% credible interval [CrI]: 32% to 69%), 24% (95% CrI: 12% to 41%) preferred amlodipine, and 12% (95% CrI: 4% to 26%) preferred hydrochlorothiazide. The preferred therapy for the majority (67%) of African American participants was lisinopril. Unacceptable side effects were reported in 24% of assessments for hydrochlorothiazide, 16% for lisinopril, and 13% for amlodipine.CONCLUSIONS: No single medication was preferred for more than half of hypertensive children. n of-1 trials with repeated ABPM may promote better informed and individualized decisions in pediatric hypertension management.
