Management of Hypertension in High-Risk Ethnic Minority with Heart Failure

Hypertension (HTN) is the most common co-morbidity in the world, and its sequelae, heart failure (HF) is one of most common causes of mortality and morbidity in the world. Current understanding of pathophysiology and management of HTN in HF is mainly based on studies, which have mainly included whites. Among racial groups, African-American adults have the highest rates (44%) of hypertension in the world and are more resistant to treatment. There is an emerging consensus on the significance of racial disparities in the pathophysiology and treatment options of hypertension and heart failure. However, African Americans had been underrepresented in all the trials until the initiation of the A-HEFT trial. Since the recognition of obstructive sleep apnea (OSA) as an important medical condition, large clinical trials have shown benefits of OSA treatment among patients with HTN and HF. This paper focuses on the pathophysiology, causes of secondary hypertension, and treatment of hypertension among African-American patients with heart failure. There is increasing need for randomized clinical trials testing innovative treatment options for African-American patients

Resistant Hypertension and Obstructive Sleep Apnea in the Primary-Care Setting

We ascertained the prevalence of resistant hypertension (RH) among blacks and determined whether RH patients are at greater risk for obstructive sleep apnea (OSA) than hypertensives. Method. Data emanated from Metabolic Syndrome Outcome Study (MetSO), a study investigating metabolic syndrome among blacks in the primary-care setting. Sample of 200 patients (mean age = 63 ± 13 years; female = 61%) with a diagnosis of hypertension provided subjective and clinical data. RH was defined using the JNC 7and European Society guidelines. We assessed OSA risk using the Apnea Risk Evaluation System ARES), defining high risk as a total ARES score ≥6. Results. Overall, 26% met criteria for RH and 40% were at high OSA risk. Logistic regression analysis, adjusting for effects of age, gender, and medical co morbidities, showed that patients with RH were nearly 2.5 times more likely to be at high OSA risk, relative to those with hypertension (OR = 2.46, 95% CI: 1.03–5.88, P < .05). Conclusion. Our findings show that the prevalence of RH among blacks fell within the range of RH for the general hypertensive population (3–29%). However, patients with RH were at significantly greater risk of OSA compared to patients with hypertension

The ANTENATAL multicentre study to predict postnatal renal outcome in fetuses with posterior urethral valves: objectives and design

Abstract Background Posterior urethral valves (PUV) account for 17% of paediatric end-stage renal disease. A major issue in the management of PUV is prenatal prediction of postnatal renal function. Fetal ultrasound and fetal urine biochemistry are currently employed for this prediction, but clearly lack precision. We previously developed a fetal urine peptide signature that predicted in utero with high precision postnatal renal function in fetuses with PUV. We describe here the objectives and design of the prospective international multicentre ANTENATAL (multicentre validation of a fetal urine peptidome-based classifier to predict postnatal renal function in posterior urethral valves) study, set up to validate this fetal urine peptide signature. Methods Participants will be PUV pregnancies enrolled from 2017 to 2021 and followed up until 2023 in >30 European centres endorsed and supported by European reference networks for rare urological disorders (ERN eUROGEN) and rare kidney diseases (ERN ERKNet). The endpoint will be renal/patient survival at 2 years postnatally. Assuming α = 0.05, 1–β = 0.8 and a mean prevalence of severe renal outcome in PUV individuals of 0.35, 400 patients need to be enrolled to validate the previously reported sensitivity and specificity of the peptide signature. Results In this largest multicentre study of antenatally detected PUV, we anticipate bringing a novel tool to the clinic. Based on urinary peptides and potentially amended in the future with additional omics traits, this tool will be able to precisely quantify postnatal renal survival in PUV pregnancies. The main limitation of the employed approach is the need for specialized equipment. Conclusions Accurate risk assessment in the prenatal period should strongly improve the management of fetuses with PUV

Transplantation rénale pédiatrique

International audienceAIMS:To describe indications, surgical aspects, results and outcomes of kidney transplantation in children.MATERIAL AND METHODS:An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords (MESH): "kidney transplantation", "pediatric", "children", "outcomes". Publications obtained were selected based on methodology, language, date of publication (last 10 years) and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 2608 articles. After reading titles and abstracts, 18 were included in the text based on their relevance.RESULTS:Kidney transplantation is the gold-standard treatment for end stage renal kidney disease in children. The surgical procedure is well standardized with a retroperitoneal approach when child and kidney size allow it or a transperitoneal approach in child less than 15 kg and big size kidney graft. Anastomosis sites include iliac vessels in the retroperitoneal approach, and inferior vena cava and aorta in case of transperitoneal procedure. Ureteral reimplantation used most of the time a Campos Freire technique. Sometimes, particular conditions in the recipient (such as vena cava thrombosis) required procedure adaptation.CONCLUSION:Graft survival dramatically increased over the past few years and is now superior to those observed in adult kidney transplantation, particularly in experienced team with microsurgery skills. Immunosuppressive treatments are similar to adults. Viral infections and post-transplant lymphoproliferative disorder are the main complications of renal transplantation in children and may lead to lethal outcomes. An increase graft loss is observed during boyhood due to immunosuppressive drugs uncompliance

Obstructive sleep apnea risk and psychological health among non-Hispanic blacks in the Metabolic Syndrome Outcome (MetSO) cohort study

INTRODUCTION: This study assessed associations of depression and anxiety with risk of OSA among Non-Hispanic Blacks in the Metabolic Syndrome Outcome (MetSO) study. METHOD: 1,035 patients provided data for the analysis. ARES™ score ≥ 6 defined high OSA risk. Moderate depression was defined by a CES-D score ≥ 16. Moderate anxiety was measured by a BAI score ≥ 16. RESULTS: The mean age was 62 ± 14 years; 70% were female. 93% were diagnosed with hypertension; 61%, diabetes; and 72%, dyslipidemia; 90% were overweight/obese; 33% had a history of heart disease and 10% had a stroke. Logistic regression analysis, adjusting for age and gender, showed that patients with depression had nearly a two-fold increased odds of being at risk for OSA (OR = 1.75, 95% CI = 1.02–2.98, p < .05). Patients with anxiety had a three-fold increased odds of being at risk for OSA (OR = 3.30, 95% CI = 2.11–5.15, p < .01). After adjusting for marital status and income, patients with anxiety had a 6% increase in OSA risk (OR=1.06, 95% CI= 1.04–1.09, p<.05) but depression was no longer significant. CONCLUSION: Our results suggest that Non-Hispanic Blacks with metabolic syndrome who experience anxiety and/or depression should be screened for OSA

Genitourinary disorders:Q 140

Clinical history and physical examination represent an important aspect in the management of infants and children with urological diseases. However, the role of instrumental and in particular of radiological examinations is fundamental for making a certain and correct diagnosis in all clinical cases
