Abstract Background and Aims High blood pressure is a leading cause of end stage renal disease (ESRD). However; early detection of chronic kidney disease (CKD) delays progression of kidney failure and reduces the risk of cardiovascular complications. Therefore, the aim of our study was to assess the attitudes and practices of interns and residents regarding screening for chronic kidney disease in patients with high blood pressure at a Moroccan University hospital. Methods A cross-sectional survey was conducted among 100 medical interns and residents at Mohammed VI university hospital of Marrakesh. Results Overall, 82% of the trainees who responded (response rate 89%) stated that they were sensitized to screening for chronic kidney disease in patients with high blood pressure, mainly during their medical studies. However, trainees who systematically monitor renal function in their hypertensive patients did not exceed 13%. While 34% of respondents preferred to refer them to a cardiologist or a nephrologist, and 35% looked for renal impairment only in special situations, dominated by the presence of diabetes or severe hypertension. The main tests used by the participants for monitoring kidney function were represented by blood renal function (100%) and 24h urine protein (61%). Microalbuminuria was mentioned by only 23% of the trainees. The major limits reported by the surveyed physicians were the lack of experience and the non- compliance of patients. Conclusion Our findings revealed inappropriate practices among our training doctors concerning the screening of CKD in hypertensive patients. Therefore, more educational workshops and courses are recommended, especially in low-income countries where access to dialysis is not always affordable.

Blood Pressure Patterns

BACKGROUND Chronic kidney disease (CKD) is a burgeoning epidemic in sub-Saharan Africa. Abnormal blood pressure variations are prevalent in CKD and potentiate the risk of cardiovascular morbidity and mortality. Certain genetic variants (angiotensin II receptor type 1 1166 A>C and angiotensin-converting enzyme insertion and deletion polymorphisms) and biomarkers such as interleukin–6, tumor necrosis factor, soluble (s) E-selectin, homocysteine, and highly sensitive C-reactive protein have been shown to affect blood pressure variability among non-African CKD, hypertensive. and nonhypertensive CKD population. However, the contributions of the pattern, genetic, and environmental determinants of ambulatory blood pressure in African CKD have not been characterized. Understanding these interactions may help to develop interventions to prevent major cardiovascular events among people with CKD. OBJECTIVE The overarching objective of this study is to identify, document, and develop approaches to address related phenomic, genetic, and environmental determinants of ambulatory blood pressure patterns in African CKD and non-CKD hypertensive patients compared with normotensive controls. METHODS This is a longitudinal short-term follow-up study of 200 adult subjects with CKD and 200 each of age-matched hypertensives without CKD and apparently healthy controls. Demographic information, detailed clinical profile, electrocardiography, echocardiography, and 24-hr ambulatory blood pressure measurements will be obtained. Blood samples will be collected to determine albumin-creatinine ratio, fasting plasma glucose, lipid profile, electrolytes, urea and creatinine, C-reactive protein, serum homocysteine, fibroblast growth factor–23, and complete blood count, while 2 mL blood aliquot will be collected in EDTA (ethylenediaminetetraacetic acid) tubes and mixed using an electronic rolling system to prevent blood clots and subsequently used for DNA extraction and genetic analysis. RESULTS A total of 239 participants have been recruited so far, and it is expected that the recruitment phase will be complete in June 2020. The follow-up phase will continue with data analysis and publications of results. CONCLUSIONS This study will help stratify Nigerian CKD patients phenotypically and genotypically in terms of their blood pressure variations with implications for targeted interventions and timing of medications to improve prognosis.

Chronic kidney disease is common in geriatric cats, but most cases have nonspecific renal lesions, and few studies have correlated these lesions with clinicopathological markers of renal dysfunction. The aim of this study was to identify the lesions best correlated with renal function and likely mediators of disease progression in cats with chronic kidney disease. Cats were recruited through 2 first-opinion practices between 1992 and 2010. When postmortem examinations were authorized, renal tissues were preserved in formalin. Sections were evaluated by a pathologist masked to all clinicopathological data. They were scored semiquantitatively for the severity of glomerulosclerosis, interstitial inflammation, and fibrosis. Glomerular volume was measured using image analysis; the percentage of glomeruli that were obsolescent was recorded. Sections were assessed for hyperplastic arteriolosclerosis and tubular mineralization. Kidneys from 80 cats with plasma biochemical data from the last 2 months of life were included in the study. Multivariable linear regression ( P < .05) was used to assess the association of lesions with clinicopathological data obtained close to death. Interstitial fibrosis was the lesion best correlated with the severity of azotemia, hyperphosphatemia, and anemia. Proteinuria was associated with interstitial fibrosis and glomerular hypertrophy, whereas higher time-averaged systolic blood pressure was associated with glomerulosclerosis and hyperplastic arteriolosclerosis.
