BACKGROUND: Mycobacterium tuberculosis (TB) is a common pathogen worldwide, and it may cause significant infection after solid organ transplantation (SOT). We reviewed all reported TB cases to provide an update on its epidemiology, clinical presentation, management and outcome after SOT. METHODS: MEDLINE, EMBASE, and OVID were reviewed from January 1, 1998 to Dec 31, 2016 using key words tuberculosis and solid organ transplant or transplantation. RESULTS: There were 187 publications reporting 2082 cases of TB among kidney (n=1719), liver (n=253), heart (n=77), lung (n=25), and kidney-pancreas (n=8) recipients...

Selenium and its derivatives including sodium selenite (sod sel) belong to the group of essential trace elements needed for proper health and nutrition. They are fairly safe and possess antioxidant and anti-inflammatory properties. The aim of present investigation was to elucidate the effect of sod sel on experimental colitis model in rats. Colitis was induced by intrarectal instillation of 4% (v/v) acetic acid. Two hours later, sod sel was given to rats on a daily basis for 15 consecutive days. Clinical symptoms, colon mass index, spleen weight inflammatory markers, hematological, biochemical, macroscopic, and histological changes were determined...

Patients associated with multiple co-occurring health conditions often face aggravated complications and less favorable outcomes. Co-occurring conditions are especially prevalent among individuals suffering from kidney disease, an increasingly widespread condition affecting 13% of the general population in the US. This study aims to identify and characterize patterns of co-occurring medical conditions in patients employing a probabilistic framework. Specifically, we apply topic modeling in a non-traditional way to find associations across SNOMED-CT codes assigned and recorded in the EHRs of >13,000 patients diagnosed with kidney disease...

BACKGROUND AND AIMS: Calcific aortic valve disease (CAVD) is the most common valve disease. Although micronutrients are known to contribute to cardiovascular disease, the relationship with CAVD remains poorly evaluated. We examined the association of serum levels of magnesium, phosphorus, and calcium with prevalence, incidence, and progression of aortic valve calcification (AVC). METHODS: We conducted a prospective study in a population-based sample of Japanese men aged 40-79 years without known cardiovascular disease and chronic kidney disease at baseline, and quantified AVC from serial computed tomographic images with the Agatston method...

Aristolochic acid I (AAI) is a phytocompound that is linked to the progressive renal disease and development of human urothelial carcinoma. The bladder cancer-associated protein (BLCAP) gene exhibits a tumor suppressor function in various tumors, including bladder carcinoma. This study evaluated the effect of AAI on BLCAP expression and its associated mechanism in human cells. Administering AAI to human embryonic kidney cells (HEK293), human proximal tubule epithelial cells (HK-2) and urinary bladder cancer cells (HT-1376) significantly reduced the expression of BLCAP mRNA and protein...

BACKGROUND: Tubulo-interstitial fibrosis (TIF) is the common pathway in the chronic kidney disease (CKD). Epithelial-to-mesenchymal transition (EMT) is a major contributor to the TIF by the increased myofibroblasts. Renin-angiotensin system (RAS) is critical mediator on EMT in progressive CKD. Angiotensin II (ANG) mediates EMT and causes TIF by stimulating transforming growth factor-β1 (TGF-β1). RAS activation could further activate TGF-β1. Inhibition of the RAS is one of the most powerful therapies for progressive CKD...

Anemia is a common complication and contributes to increased morbidity and mortality in chronic kidney disease (CKD) patients. Whereas there has been a significant improvement of understanding the underlying mechanism of erythropoiesis, the treatment of renal anemia is still restricted to erythropoietin (EPO)-stimulating agents. The purpose of this article is to review the physiology of erythropoiesis, functional role of EPO and underlying molecular and cellular basis that regulate EPO production. Regulation of EPO production is at mRNA level...

Treatment effectiveness for kidney disease is limited by lack of accuracy, sensitivity, specificity of diagnostic, prognostic, and therapeutic biomarkers. The gold standard test renal biopsy along with serum creatinine and proteinuria is often necessary to establish a diagnosis, particularly in glomerular disease. Proteomics has become a powerful tool for novel biomarker discovery in kidney disease. Novel proteomics offer earlier and more accurate diagnosis of renal pathology than possible with traditional biomarkers such as serum creatinine and urine protein...

Adiponectin circulates in blood in multiple isoforms. High molecular weight (HMW) adiponectin is thought to be most biologically active and promotes glucose uptake, insulin sensitivity, and fatty acid oxidation. In obesity, adiponectin isoform formation is disrupted, leading to an inverse association between metabolic disease and HMW and total adiponectin. Adiponectin isoforms also function as acute-phase reactants influencing inflammation in acute and chronic disease. Interestingly, adiponectin and mortality have a U-shaped association...

The final strategies to care patients with end-stage renal fibrosis rely on dialysis and kidney transplantation. Because such treatments are invasive and cause health problems eventually, it is necessary to develop new therapeutic strategies for delaying the disease progress. We here searched for cytokines showing an anti-fibrotic activity in cell-based experiments. Cystatin C (CST3) and Growth differentiation factor 15 (GDF15) were identified to have anti-fibrotic activities in a cytokine array screening. In primary fibroblasts isolated from the mouse kidneys subjected to ureteral obstruction-induced fibrosis, each cytokine induced apoptotic cell death and reduced collagen production...

Uremic retention solutes (URS) are associated with cardiovascular complications and poor survival in chronic kidney disease. The better understanding of the origin of a certain number of these toxins enabled the development of new strategies to reduce their production. URS can be classified according to their origins (i.e., host, microbial, or exogenous). The discovery of the fundamental role that the intestinal microbiota plays in the production of many URS has reinstated nutrition at the heart of therapeutics to prevent the accumulation of URS and their deleterious effects...

Mesangial matrix expansion is an important process in the initiation of chronic kidney disease, yet the genetic factors driving its development are unknown. Our previous studies have implicated Far2 as a candidate gene associated with differences in mesangial matrix expansion between mouse inbred strains. Consistent with the hypothesis that increased expression of Far2 leads to mesangial matrix expansion through increased production of platelet-activating factor precursors, we show that FAR2 is capable of mediating de novo platelet-activating factor synthesis in vitro and driven by the transcription factor NKX3...

Objectives The aim of this study was to establish ultrasound criteria for the diagnosis of autosomal dominant polycystic kidney disease (ADPKD) in Persian cats. Methods Eighty-two Persian cats were assessed using renal ultrasound and genotyped for the C→A transversion in exon 29 of PKD1. The animals were also submitted to hematological characterization, serum biochemistry analyses and urinalysis. Results Age, sex and neutering status did not differ between ADPKD (n = 12) and non-ADPKD (n = 70) cats. After integrated molecular genetics/ultrasonographic analysis, the presence of at least one renal cyst was sufficient to establish a diagnosis of ADPKD in animals up to 15 months of age...
