BACKGROUND: Renal disease is considered the main cause of natural mortality in dogs with canine leishmaniosis. The pathological mechanisms associated with kidney injury in canine leishmaniosis include immune complex glomerulonephritis, tubulointerstitial nephritis and occasionally renal amyloidosis. Proteinuria is a frequent finding in canine leishmaniosis and its quantification by the urine protein-creatinine ratio (UPC) is an important parameter in the staging of canine lesihmaniosis as presented by the LeishVet group...

Recent evidence suggests that renal tubular injury plays a key role in deterioration of renal function in both chronic kidney disease (CKD) and acute kidney injury (AKI). Since commonly used biochemical indicators such as GFR, serum creatinine, blood urea nitrogen and creatinine clearance are inappropriate for detecting alteration in renal tubules, biomarkers reflecting renal tubular injury have been extensively explored. Our research group identified leucine rich α-2 glycoprotein (LRG) as a novel serum biomarker for various inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease...

This study aimed to investigate the association of nonalcoholic fatty liver disease (NAFLD) and its severity with the decline in kidney function in patients with chronic kidney disease (CKD). We conducted a cohort study of 1,525 CKD patients who underwent repeated health check-up examinations from January 2003 through December 2013. NAFLD was diagnosed by ultrasonography and its severity was assessed by the NAFLD fibrosis score. At baseline, the prevalence of NAFLD was 40.9%, and the mean estimated glomerular filtration rate (eGFR) was 59...

There is ongoing recognition that a wide array of social, economic, and environmental factors influence individuals' opportunities to engage in health care and healthy behaviors. Despite spending $34 billion annually on the care of patients with end-stage renal disease, the American public and nephrology community remain remarkably complacent about addressing "upstream" factors that influence the prevention, progression, and treatment of chronic kidney diseases. Recently, a growing number of health plans and dialysis providers have begun to embrace population health management; accept greater accountability for health, health care, and health costs; and envision kidney health beyond their traditional roles in care delivery...

Secondary hyperparathyroidism (SHPT) is one of the most frequent and deleterious complication of chronic kidney disease (CKD). SHPT is also one of the principal components of the now called CKD-mineral and bone disorders (MBD) syndrome. It is usually prevented and treated by vitamin D derivatives. However, the rationale for the prescription of vitamin D sterols in those patients is still a matter of hotly debates, mainly because of unsatisfactory results from numerous observational and not well-controlled studies...

Chronic kidney disease affects more than 10% of the population. Programming studies have examined the interrelationship between environmental factors in early life and differences in morbidity and mortality between individuals. A number of important principles has been identified, namely permanent structural modifications of organs and cells, long-lasting adjustments of endocrine regulatory circuits, as well as altered gene transcription. Risk factors include intrauterine deficiencies by disturbed placental function or maternal malnutrition, prematurity, intrauterine and postnatal stress, intrauterine and postnatal overnutrition, as well as dietary dysbalances in postnatal life...

Background: Nephrotic syndrome (NS), a chronic kidney disease, is characterized by significant loss of protein in the urine causing hypoalbuminemia and edema. In general, ∼15% of childhood-onset cases do not respond to steroid therapy and are classified as steroid-resistant NS (SRNS). In ∼30% of cases with SRNS, a causative mutation can be detected in one of 44 monogenic SRNS genes. The gene LAMA5 encodes laminin-α5, an essential component of the glomerular basement membrane. Mice with a hypomorphic mutation in the orthologous gene Lama5 develop proteinuria and hematuria...

Chronic graft-versus-host disease (cGVHD) is characterized as autoimmune-like fibrosis and antibody production mediated by pathogenic T-cells and B-cells. MicroRNA (miR)-17-92 influences the survival, differentiation and function of lymphocytes in cancer, infections and autoimmunity. To determine whether miR-17-92 regulates T- and B-cell responses in cGVHD, we generated mice conditionally deficient for miR-17-92 in T-cells, B-cells, or both. Using murine models of allogeneic bone marrow transplantation (allo-BMT), we demonstrate that expression of miR-17-92 in donor T- and B-cells is essential for the induction of both scleroderma and bronchiolitis obliterans in cGVHD...

BACKGROUND AND OBJECTIVE: Diagnosis of lupus nephritis (LN) is usually based on renal biopsy, which is an invasive technique that involves multiple risks. Therefore, different biomarkers have emerged as alternatives for the diagnosis of LN. Nonetheless, studies regarding urinary biomarkers in Latin American patients are limited. The objective of this study was to assess the diagnostic value of urinary transferrin and ceruloplasmin to differentiate patients who have renal involvement from those who do not...

Alport syndrome is due to mutations in one of the genes encoding (α3,4,5) type IV collagen resulting in defective type IV collagen, a key component of the glomerular basement membrane (GBM). The GBM is initially thin, and with ongoing remodeling, develops a thickened basket-woven appearance. We report a unique case of a 9-year-old boy who was biopsied for hematuria and proteinuria, diagnosed as IgA nephropathy, with normal GBM appearance and thickness. Due to a family history of hematuria and chronic kidney disease, he subsequently underwent genetic evaluation and a mutation of α3 type IV collagen (COL4A3) was detected...

A 12-year-old girl born to third-degree consanguineous parents presented with recurrent episodes of haematuria for 8 months in association with peri-orbital and lower limb oedema for 20 days. There was no jaundice, hepatomegaly or neurological abnormality at presentation. An older brother had died following jaundice at 10 years of age. Urinalysis showed multiple dysmorphic erythrocytes without proteinuria and there was leucopenia, thrombocytopenia and hypo-albuminaemia (23 g/L). C3 component of complementaemia was low and anti-nuclear antibodies and anti-double-stranded DNA antibodies were strongly positive by immunofluorescence...

BACKGROUND: Prognostic uncertainty inhibits clinicians from initiating timely end-of-life discussions and advance care planning. This study evaluates the efficacy of the CriSTAL (Criteria for Screening and Triaging to Appropriate aLternative care) checklist in emergency departments. METHODS: Prospective cohort study of patients aged ≥65 years with any diagnosis admitted via emergency departments in ten hospitals in Australia, Denmark and Ireland. Electronic and paper clinical records will be used to extract risk factors such as nursing home residency, physiological deterioration warranting a rapid response call, personal history of active chronic disease, history of hospitalisations or intensive care unit admission in the past year, evidence of proteinuria or ECG abnormalities, and evidence of frailty to be concurrently measured with Fried Score and Clinical Frailty Scale...

Zhen-wu-tang (ZWT) has been widely applied in chronic kidney diseases. However, the mechanism of ZWT remains unclear. Peroxisome proliferator-activated receptors-γ (PPARγ) is known as a protective factor for podocyte and kidney function. This study is aimed to investigate the protective effects of ZWT on IgA nephropathy (IgAN) in rats against podocyte injury and the underlying mechanism related to PPARγ. IgAN model rats were induced by administering bovine serum albumin, lipopolysaccharide, and carbon tetrachloride...

Screening of individuals at increased risk of developing chronic kidney disease (CKD) has been advocated by several guidelines. Among individuals at increased risk are first-degree relatives (FDRs) of patients with CKD. There is a paucity of data on the prevalence and risk of CKD in FDRs of patients with CKD in sub-Saharan African population. This study aimed to screen FDRs of patients with CKD for albuminuria and reduced estimated glomerular filtration rate (eGFR). A cross-sectional survey of 230 FDRs of patients with CKD and 230 individuals without family history of CKD was conducted...

BACKGROUND: Proteinuria is well recognised as a marker of chronic kidney disease (CKD), as a risk factor for progression of CKD among those with known CKD, and as a risk factor for cardiovascular events and death among both the general and CKD populations. Which measure of proteinuria is most predictive of renal events remains uncertain. METHODS: We conducted a prospective study with 144 proteinuric CKD and kidney transplant recipients attending an outpatient clinic of a tertiary care hospital in Australia...

Background: No study has assessed whether the prognosis of coexisting diabetes mellitus and chronic kidney disease (DM-CKD) is dictated by DM per se or by the extent of proteinuria. Methods: In this pooled analysis of four prospective studies in CKD patients treated with drugs inhibiting the renin-angiotensin system, we compared the risk of all-cause mortality, fatal and non-fatal cardiovascular (CV) events and end-stage renal disease (ESRD) between patients with (n = 693) and without diabetes (n = 1481) stratified by proteinuria level (<0...
