Hypertension prevalence rates in most urbanized areas of Africa range from 20-30%, with a recent systematic review reporting 16.2% for sub-Saharan Africa. These rates are lower than those in the West but the age standardized rates are higher than in other regions of the world. The attendant morbidity and mortality are disproportionately high. For example, failure of nocturnal dipping and microalbuminuria, predictive of vascular disease, occur relatively early in the course of hypertension and predispose to early vascular disease...

INTRODUCTION: We report the case of a multicentric Castleman disease (MCD) with initial renal involvement. Although the renal involvement in this case was typical of MCD, it constitutes a rare presentation of the disease, and in our case the renal manifestations led to the haematological diagnosis. CLINICAL FINDINGS/PATIENT CONCERNS: The patient was admitted for fever, diarrhea, anasarca, lymphadenopathies and acute renal failure. Despite intravenous rehydration using saline and albumin, renal function worsened and the patient required dialysis...

Patients with advanced chronic renal dysfunction were excluded from randomized trials of transcatheter aortic valve replacement (TAVR). The potential impact of chronic renal disease on TAVR prognosis is not fully understood. We aim to evaluate outcomes within a large cohort of patients who underwent TAVR distinguished by renal function. Baseline characteristics, procedural data, and clinical follow-up findings were collected from 10 high-volume TAVR centers in Europe, Israel, and Japan. Data were analyzed according to renal function...

Blood pressure is a modifiable risk for cardiovascular disease (CVD). Among hemodialysis patients, there is a U-shaped association between blood pressure and risk of death. However, few studies have examined the association between blood pressure and CVD in patients with stage 4 and 5 chronic kidney disease. Here we studied 1795 Chronic Renal Insufficiency Cohort (CRIC) Study participants with estimated glomerular filtration rate <30 ml/min per 1.73 m(2) and not on dialysis. The association of systolic (SBP), diastolic (DBP), and pulse pressure with the risk of physician-adjudicated atherosclerotic CVD (stroke, myocardial infarction, or peripheral arterial disease) and heart failure was tested using Cox regression adjusted for demographics, comorbidity and medications...

OBJECTIVES: The purpose of this study was to evaluate the clinical impact of chronic kidney disease (CKD) on clinical outcomes in contemporary practice of percutaneous coronary intervention (PCI) using second-generation drug-eluting stents (DES). BACKGROUND: Although second-generation DES have improved the safety and efficacy issues in PCI, data regarding the performance of second-generation DES in patients with CKD are still limited. METHODS: We performed a patient-level pooled analysis on 12,426 patients undergoing PCI using second-generation DES from the Korean Multicenter Drug-Eluting Stent Registry...

There is limited data on the etiology, clinical and histopathological spectrum and outcomes of crescentic glomerulonephritis (CrGN) in adult Indian population. This prospective study was done to evaluate the etiology, clinicohistological patterns and predictors of outcome of CrGN in South Indian population. All the patients received standard protocol based immunosuppression in addition to supportive care. Immune-complex glomerulonephritis (ICGN) was the most common etiology (n = 31; 77.5%) followed by pauci-immune glomerulonephritis (PauciGN; n = 8; 20%) and anti-glomerular basement membrane disease (n = 1; 2...

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease (ESRD) in the United States and other developed countries. In 1982, diabetes accounted for 27% of patients with ESRD in the United States and rose to 36% by 1992 and to 47% in 2012. Currently, the number of prevalent cases of ESRD in the country (dialysis and transplant) exceeds more than 636,900. Primary care practitioners (PCP) provide more than 90% of the diabetic care and are well-positioned to identify, prevent, and treat initially DN...

Recipient diabetes accounts for ~34% of end stage renal disease in patients awaiting renal transplantation and has been linked to poor graft function. We conducted a single center, open label, randomized controlled trial to determine if moderately intense glucose control during allograft reperfusion would reduce the incidence of poor graft function. Adult diabetics undergoing deceased donor renal transplant were randomized to moderately intense glucose control (n=30) or standard control (n=30). The primary outcome was poor graft function (dialysis within seven days of transplant or failure of serum creatinine to fall by 10% for three consecutive days)...

BACKGROUND: Patients with autosomal or X-linked Alport syndrome (AS) with heterozygous mutations in type IV collagen genes have a 1-20 % risk of progressing to end-stage renal disease during their lifetime. We evaluated the long-term renal outcome of patients at risk of progressive disease (chronic kidney disease stages 1-4) with/without nephroprotective therapy. METHODS: This was a prospective, non-interventional, observational study which included data from a 4-year follow-up of AS patients with heterozygous mutations whose datasets had been included in an analysis of the 2010 database of the European Alport Registry...

BACKGROUND: Increasing evidence indicated that phosphorus emerged as an important cardiovascular risk factor in patients with chronic kidney disease (CKD). The fact that serum phosphorus was closely linked to vascular and valvar calcification may account for one important reason. However, left ventricular remodeling may also serve as another potential mechanism of the cardiac toxicity of phosphorus. In the present study, we evaluated the association of serum phosphorus with left ventricular remodeling...

Chronic kidney disease (CKD) is a worldwide public health problem associated with a high prevalence of cardiovascular disease (CVD) and impaired quality of life. Previous research for preventing loss of glomerular filtration rate (GFR) has focused on reducing blood pressure (BP) and proteinuria. Angiotensin converting enzyme inhibitors (ACEi) and angiotensin II receptor antagonists (ARB) are commonly used in patients with early CKD, but their value in advanced CKD (estimated GFR (eGFR) ≤30 ml/min/1.73 m2) is unknown...

BACKGROUND: There remains concern that moderate hypothermic circulatory arrest (MHCA) with antegrade cerebral perfusion (ACP) may provide suboptimal distal organ protection compared with deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (RCP). We compared postoperative acute kidney injury (AKI) in in patients who underwent elective hemiarch repair with either DHCA/RCP or MHCA/ACP. METHODS: This was a retrospective review of all patients undergoing elective aortic hemiarch reconstruction for aneurysmal disease between 2009 and 2014...

BACKGROUND: Monitoring of renal function is important in patients with chronic kidney disease progressing towards end-stage renal failure, both for timing the start of renal replacement therapy and for determining the prognosis on dialysis. Thus far, studies on associations between estimated glomerular filtration rate (eGFR) measurements in the pre-dialysis stage and mortality on dialysis have shown no or even inverse relations, which may result from the poor validity of serum creatinine-based estimation equations for renal function in pre-dialysis patients...

The paper describes a clinical case of a female woman with nephropathy due to light chain deposition disease caused by secretion of κ Bence-Jones protein. Complete immunochemical remission was achieved after induction therapy using a bortezomib + cyclophosphamide + dexamethasone regimen. Renal function remained unchanged (glomerular filtration rate 16 ml/min), there was a reduction in proteinuria from 5.8 to 2.6 g/day. High-dose melphalan (200 mg/m2) chemotherapy with peripheral blood stem cell autotransplantation was performed as consolidation of remission...

Methylmalonic aciduria and homocystinuria, cobalamin C (cblC) type, is the most common genetic type of functional cobalamin (vitamin B12) deficiency. This metabolic disease is characterized by marked heterogeneity of neurocognitive disease (microcephaly, seizures, developmental delay, ataxia, hypotonia) and variable extracentral nervous system involvement (failure to thrive, cardiovascular, renal, ocular) manifesting predominantly early in life, sometimes during gestation. To enhance awareness and understanding of renal disease associated with cblC defect, we studied biochemical, genetic, clinical, and histopathological data from 36 patients...

BACKGROUND: Critically ill patients with acute kidney injury (AKI) in need of renal replacement therapy (RRT) may have a protracted and often incomplete rehabilitation. Their long-term outcome has rarely been investigated. STUDY DESIGN: Survivors of the HANnover Dialysis OUTcome (HANDOUT) study were evaluated after 5 years for survival, health status, renal function, and quality of life (QoL). The HANDOUT study had examinded mortality and renal recovery of patients with AKI receiving either standard extendend or intensified dialysis after multi organ failure...

Antiglomerular basement membrane (GBM) disease is known as a super-acute proliferative glomerulonephritis caused by auto-antibodies targeting the NC1 domain of the α3 chain of type IV collagen.Here, we describe a case of atypical anti-GBM disease presenting as a dialysis-dependent acute renal failure with unusual mild glomerular involvement. We found that immunoglobulin G (IgG) deposits were restricted to the uncommon IgG2 and IgG4 subclasses, and that blood was positive for anti-GBM antibodies by immunofluorescence, but not by Enzyme Linked Immunosorbent Assay (ELISA)...

BACKGROUND: Few studies have been conducted on the long-term prognosis of patients with amyloid light chain (AL) and amyloid A (AA) renal amyloidosis in the same cohort. METHODS: We retrospectively examined 68 patients with biopsy-proven renal amyloidosis (38 AL and 30 AA). Clinicopathological findings at the diagnosis and follow-up data were evaluated in each patient. We analyzed the relationship between clinicopathological parameters and survival data. RESULTS: Significant differences were observed in several clinicopathological features, such as proteinuria levels, between the AL and AA groups...
