Intronic variants of the MYH9 gene that encodes the nonmuscle myosin heavy chain IIA are associated with diabetic nephropathy in European Americans and with sickle cell disease-associated nephropathy. However, the causal functional variants of MYH9 have remained elusive. Rare missense mutations in MYH9 cause macrothrombocytopenia and are occasionally associated with development of nephropathy. The E1841K mutation is among the common MYH9 missense mutations and has been associated with nephropathy in some carriers...

BACKGROUND & AIMS: Increasing evidence suggests that non-alcoholic fatty liver disease (NAFLD) may be an independent risk factor for chronic kidney disease (CKD). Given the high prevalence of NAFLD among patients with diabetes who are also at risk for CKD, we aimed to investigate the association between NAFLD and albuminuria, a marker commonly found in diabetic nephropathy. METHODS: This study included a cohort of Chinese patients with type 2 diabetes from the Hong Kong Diabetes Registry recruited between March 2013 and May 2014...

Obesity-related structural and functional changes in the kidney develop early in the course of obesity and occur independently of hypertension, diabetes, and dyslipidemia. Activating the renal cannabinoid-1 receptor (CB1R) induces nephropathy, whereas CB1R blockade improves kidney function. Whether these effects are mediated via a specific cell type within the kidney remains unknown. Here, we show that specific deletion of CB1R in the renal proximal tubule cells did not protect the mice from obesity, but markedly attenuated the obesity-induced lipid accumulation in the kidney and renal dysfunction, injury, inflammation, and fibrosis...

Chronic kidney disease (CKD) has become a major public health problem in Brazil and worldwide. There are many causes of CKD, being the congenital anomalies of the kidney and urinary tract and the glomerular diseases very common in pediatric patients, while diabetic nephropathy, CKD due to chronic arterial hypertension and glomerular diseases are predominant in adult patients. Many endogenous mediators have been related to the pathophysiology of CKD, being relevant the effects of the renin-angiotensin system (RAS) and the immune-inflammatory mediators including cytokines...

CKD, diabetes and cardiovascular disease constitute three interrelated conditions of strong public health relevance. Elderly individuals account for the largest and the most rapidly growing age segment of the ESRD population. The elderly are affected by the same types of kidney diseases as younger individuals, but aging itself is associated with a gradual reduction in eGFR, which leads to the diminishment of the functional reserve and makes an individual more vulnerable to injurious effects of hypertension, cardiovascular disease, diabetes, and drugs' toxicity...

Mesoamerican nephropathy (MeN), an epidemic of unexplained kidney disease in Central America, affects mostly young, healthy individuals. Its etiology is a mystery that requires urgent investigation. Largely described as a chronic kidney disease (CKD), no acute clinical scenario has been characterized. An understanding of the early disease process could elucidate an etiology and guide treatment and prevention efforts. We sought to document the earliest clinical signs in patients with suspected MeN in a high-risk population in Nicaragua...

Chronic kidney disease (CKD) is a significant health problem associated with high morbidity and mortality. Despite significant research into various pathways involved in the pathophysiology of CKD, the therapeutic options are limited in diabetes and hypertension induced CKD to blood pressure control, hyperglycemia management (in diabetic nephropathy) and reduction of proteinuria, mainly with renin-angiotensin blockade therapy. Recently, renal oxygenation in pathophysiology of CKD progression has received a lot of interest...

REVIEW
Maria Dolores Sanchez-Niño, Ana B Sanz, Adrian M Ramos, Marta Ruiz-Ortega, Alberto Ortiz
The KDIGO definition of chronic kidney disease (CKD) allowed a more detailed characterization of CKD causes, epidemiology and consequences. The picture that has emerged is worrisome from the point of view of translation. CKD was among the fastest growing causes of death in the past 20 years in age-adjusted terms. The gap between recent advances and the growing worldwide mortality appears to result from sequential roadblocks that limit the flow from basic research to clinical development (translational research type 1, T1), from clinical development to clinical practice (translational research T2) and result in deficient widespread worldwide implementation of already available medical advances (translational research T3)...

COMMENT
Maria D Sanchez-Niño, Alberto Ortiz
In this issue of CKJ, McQuarrie et al. have explored the relationship between socioeconomic status and outcomes among Scottish patients with a renal biopsy diagnosis of primary glomerulonephritis. Patients in the lower socioeconomic category had a twofold higher risk of death. No significant differences were observed on progression to end-stage renal disease (ESRD) requiring renal replacement therapy (RRT), suggesting that overall medical management was appropriate for all socioeconomic categories. The findings are significant since they come from an ethnically homogeneous population with free access to healthcare; they also relate to a specific aetiology of chronic kidney disease (CKD) expected to be less dependent on unhealthy lifestyles than other more frequent aetiologies that dominate studies of CKD in general, such as diabetic or hypertensive nephropathy...

BACKGROUND: Blood pressure (BP) variation is commonly encountered during hemodialysis (HD) procedure. Both intradialysis hypotension and hypertension have implications for outcome of treatment and overall morbidity and mortality of the patients. METHODOLOGY: A retrospective study was carried out in the dialysis unit of a tertiary health institution in Benin City among patients who had HD for acute kidney injury (AKI) or chronic kidney disease (CKD) over a 3-year period...

PURPOSE OF REVIEW: Mesoamerican nephropathy (MeN) is an emerging pathophysiological entity of Chronic kidney desease (CKD) not related to traditional risk factors (diabetes and hypertension) that have caused thousands of deaths in Central America, mainly in sugarcane workers. The focus of this review is to discuss the risk factors and probable mechanisms involved in the initiation and progression of this devastating disease. RECENT FINDINGS: Frequent episodes of subclinical Acute kidney injury caused by repetitive heat stress, dehydration, and strenuous work have been regarded as the main risk factors for MeN...

Angiotensin converting enzyme(ACE) 2 is a homologue of ACE that catalyzes the conversion of Angiotensin(Ang) II into Ang1-7, which induces vasodilation, anti-fibrotic, anti-proliferative and anti-inflammatory effects. Given that ACE2 counterbalances the effects of Ang II, it has been proposed as a biomarker in kidney disease patients. Circulating ACE2 has been studied in human and experimental studies under physiological and pathological conditions and different techniques have been assessed to determine its enzymatic activity...

Obesity has been pointed out as an important cause of kidney diseases. Due to its close association with diabetes and hypertension, excess weight and obesity are important risk factors for chronic kidney disease (CKD). Obesity influences CKD development, among other factors, because it predisposes to diabetic nephropathy, hypertensive nephrosclerosis and focal and segmental glomerulosclerosis. Excess weight and obesity are associated with hemodynamic, structural and histological renal changes, in addition to metabolic and biochemical alterations that lead to kidney disease...

Proteinuria is a distinguishing feature in primary and secondary forms of chronic glomerulonephritis, which contribute to no more than the 20% of the end-stage kidney disease (ESKD) population. The contribution of non-proteinuric nephropathies to the global ESKD burden is still poorly focused and scarce research efforts are dedicated to the elucidation of risk factors and mechanistic pathways triggering ESKD in these diseases. We abstracted information on proteinuria in the main renal diseases other than glomerulonephritides that may evolve into ESKD...

In spite of the interest for chronic renal diseases (CKD) in pregnancy data on specific diseases is fragmentary; while recent studies analysed the most common glomerulonephritides (GN), none was addressed at GN as a group. The aim of our study was to analyse the main pregnancy-related outcomes in GN patients in a large multicentre cohort. Patients with a diagnosis of GN were selected from the TOCOS cohort (TOCOS: TOrino Cagliari Observational Study): out of 714 singleton deliveries GN was the diagnosis in 126; lupus GN and IgA nephropathy accounted for 37 and 33 cases; 1418 low-risk singleton deliveries followed-up in the same Centers served as controls (non diabetic, non nephropathic, non obese women, without any other known chronic illness; pregnancies after ovodonation or in vitro fertilisation were excluded, if declared)...

Beetroot has a high concentration of inorganic nitrate, which can serially reduced to form nitrite and nitric oxide (NO) after oral ingestion. Increased renal resistive index (RRI) measured by Doppler ultrasonography is associated with higher cardiovascular mortality in hypertensive patients with reduced renal function over time defined as chronic kidney disease (CKD). Our aim was to investigate whether the supplementation of dietary nitrate by administration of beetroot juice is able to reduce blood pressure and renal resistive index (RRI) as prognostic markers for cardiovascular mortality in CKD patients...
