The aim of this study was to evaluate the benefits and risks of omega-3 fatty acid supplementation in patients with chronic kidney disease. A systematic search of articles in PubMed, Embase, the Cochrane Library, and reference lists was performed to find relevant literature. All eligible studies assessed proteinuria, the serum creatinine clearance rate, the estimated glomerular filtration rate, or the occurrence of end-stage renal disease. Standard mean differences with 95% confidence intervals for continuous data were used to estimate the effects of omega-3 fatty acid supplementation on renal function, as reflected by the serum creatinine clearance rate, proteinuria, the estimated glomerular filtration rate, and relative risk...

Autophagy is a highly conserved degradation process that is involved in the clearance of proteins and damaged organelles to maintain intracellular homeostasis and cell integrity. Type 2 diabetes is often accompanied by dyslipidemia with elevated levels of free fatty acids (FFAs). Podocytes, as an important component of the filtration barrier, are susceptible to lipid disorders. The loss of podocytes causes proteinuria, which is involved in the pathogenesis of diabetic nephropathy. In the present study, we demonstrated that palmitic acid (PA) promoted autophagy in podocytes...

The traditional Chinese medicine (Tripterygium wilfordiiHook.f., TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years. However, there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN). This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP, in order to investigate the effects of triptolide on the expression of OCP in rats with DN...

Poly(ADP-ribose) polymerase (PARP) enzyme contributes to nephropathy, a serious diabetic complication which may lead to end-stage renal disease. The study aims to investigate the effect of PARP over-activation on kidney functions in a type 2 diabetic rat model. The study also tests the therapeutic use of PARP inhibitors in diabetic nephropathy. Type 2 diabetes was induced in adult male rats by high-fructose/high-fat diet and low streptozotocin dose. Then, the PARP inhibitor 4-aminobenzamide (4-AB) was administered daily for 10 weeks...

BACKGROUND: Membranous nephropathy (MN) is the most common cause of nephrotic syndrome in adults. As many clinical cases have reported, it may be associated with hepatitis C virus (HCV) infection. Antiviral therapy can be various. CASE SUMMARY: We report a case of patient with chronic HCV infection and MN, who presented with was proteinuria. He was treated with ledipasvir and sofosbuvir (Harvoni; Gilead Sciences, Foster City, CA) and was found to be virus-free. CONCLUSION: We have reported this case to provide insight into whether Ledipasvir-Sofosbuvir should be administered for HCV-related glomerulonephritis...

Foxc1 and Foxc2 (Foxc1/2) are transcription factors involved in many biological processes. In adult kidneys, expression of Foxc1/2 is confined to the glomerular epithelial cells, i.e., podocytes. To bypass embryonic lethality of Foxc1/2 null mice, mice ubiquitously expressing inducible-Cre (ROSA26-CreER(T2)) or mice expressing Cre in podocytes (Nephrin-Cre) were mated with floxed-Foxc1 and floxed-Foxc2 mice. The CreER(T2) was activated in adult mice by administrations of tamoxifen. Eight weeks after tamoxifen treatment, ROSA26-CreER(T2); Foxc1(+/flox); Foxc2(flox/flox) mice developed microalbuminuria, while ROSA26-Cre ER(T2); Foxc1(flox/flox); Foxc2(+/flox) mice had no microalbuminuria...

PURPOSE OF REVIEW: To provide an update on recent developments since the publication of the Oxford Classification of IgA nephropathy and to consider lesions that were not included in the original classification. RECENT FINDINGS: Over 20 validation studies of the Oxford Classification have been published. Tubular atrophy/interstitial fibrosis is consistently the strongest predictor of renal survival, whereas mesangial hypercellularity predicts rate of loss of renal function...

Anticoagulant-related nephropathy is a type of acute kidney injury caused by overcoagulation. We describe a case of an 84-year-old man with arterial hypertension, coronary heart disease and atrial fibrillation treated with acenocoumarol, who presented with haematoproteinuria and acute kidney injury during a phase of excessive anticoagulation. In addition to IgA nephropathy, renal biopsy also revealed acute tubular necrosis, red blood cell casts and positive iron staining in tubular cells. After this acute episode, renal function improved and proteinuria decreased below the nephrotic range...

Glomerular damage mediated by glomerulus-infiltrating myeloid-derived cells is a key pathogenic event in lupus nephritis (LN), but the process is poorly understood. Confocal microscopy of kidney sections and flow cytometry analysis of glomerular cells from magnetic bead-purified glomeruli have identified glomerulus-infiltrating leukocyte populations in NZM2328 (NZM) lupus-prone mice with spontaneous chronic glomerulonephritis (GN) and anti-glomerular basement membrane-induced nephritis. The occurrence of a major glomerulus-infiltrating CD11b(+)F4/80(-)I-A(-) macrophage population exhibiting the markers programmed death ligand-1 (PD-L1), Mac-2, and macrophage mannose receptor (CD206) and producing Klf4, Il10, Retnla, Tnf, and Il6 mRNA, which are known to be expressed by alternatively activated (M2b) macrophages, correlated with proteinuria status...

BACKGROUND: Chronic allograft dysfunction (CAD) is the most important clinical problem in solid organ transplantation. Interstitial fibrosis and tubular atrophy contribute to long-term renal allograft failure. Urinary type III procollagen N-terminal propeptide (PIIINP), has been shown to associate fibrotic processes. METHODS: One hundred sixty patients with CAD who underwent allograft biopsies were evaluated, and 52 patients with chronic or sclerosing allograft nephropathy were enrolled in the study...

To better clarify the clinical features and therapeutic strategy of CMV infection in lupus nephritis patients, we retrospectively surveyed a total of 40 lupus nephritis patients, who had been hospitalized and underwent renal biopsy and diagnosed as having CMV infection during their hospitalization at our institution within the last 10 years. The percentage of CMV infections in the entire hospitalized lupus nephritis population was 5.3% (40/755). The principal clinical features of the 40 CMV-infected patients were hematological disorders (n = 25), fever (n = 21), liver dysfunction (n = 19), and respiratory symptoms (n = 12)...

OBJECTIVE: To compare the prevalence of proteinuria in the urology clinic with other outpatient settings. Chronic kidney disease (CKD) is classified according to cause, GFR, and proteinuria. Proteinuria may be more prevalent patients with known CKD, renal disorders (benign or malignant), and/or after urologic surgery. METHODS: Cross-sectional study of 3 populations undergoing urinalysis (UA) testing: general outpatients (n=20,334), urology outpatients (n=5,023), and kidney cancer patients (n=1,016)...

BACKGROUND: Since 1984, WHO has endorsed drug treatment to reduce Schistosoma infection and its consequent morbidity. Cross-sectional studies suggest pre-treatment correlation between infection intensity and risk for Schistosoma-related pathology. However, evidence also suggests that post-treatment reduction in intensity may not reverse morbidity because some morbidities occur at all levels of infection, and some reflect permanent tissue damage. The aim of this project was to systematically review evidence on drug-based control of schistosomiasis and to develop a quantitative estimate of the impact of post-treatment reductions in infection intensity on prevalence of infection-associated morbidity...

CKD patients with low-grade proteinuria (LP) are common in nephrology clinics. However, prevalence, characteristics, and the competing risks of ESRD and death as the specific determinants, are still unknown. We analyzed epidemiological features of LP status in a prospective cohort of 2,340 patients with CKD stage III-V referred from ≥6 months in 40 nephrology clinics in Italy. LP status was defined as proteinuria <0.5 g/24h according to current KDIGO guidelines. Patients with higher proteinuria constituted the control group (CON)...

An 11-year-old Hispanic female underwent evaluation of asymptomatic proteinuria and hematuria. The patient denied fever, edema, and gross hematuria. Urinalysis showed mild proteinuria, and a urine microscopic examination revealed red blood cells. Screening tests for glomerulonephritis revealed a low C3 and negative ANA, ASO, DNAse-B, and ANCA. Histological examination of a renal biopsy specimen showed glomeruli with endocapillary proliferation, a predominant C3 deposition in the capillary loops by immunofluorescence, and electron dense deposits in the mesangium, paramesangium, and capillary walls by electron microscopy consistent with a diagnosis of C3 glomerulopathy...

Philip Webster, Liz Lightstone, Dianne B McKay, Michelle A Josephson
Chronic kidney disease (CKD) affects up to 6% of women of childbearing age in high income countries, and is estimated to affect 3% of pregnant women. Advanced renal dysfunction, proteinuria, hypertension, and poorly controlled underlying primary renal disease are all significant risks for adverse maternal, fetal, and renal outcomes. In order to achieve the best outcomes, it is therefore of paramount importance that these pregnancies are planned, where possible, to allow the opportunity to counsel women and their partners in advance and to optimize these risks...
