INTRODUCTION: Dolutegravir may inhibit creatinine transporters in renal tubules and elevate serum creatinine levels. We investigated the usefulness of glomerular filtration rate (GFR) measured using inulin clearance (Cin), creatinine clearance (Ccr), and estimated GFR based on both serum creatinine (eGFRcre) and serum cystatin C (eGFRcys). PATIENTS & METHODS: HIV-1-infected Japanese patients with suppressed viremia and whose antiretroviral drug was switched to dolutegravir from other drugs were included (n = 108, Study 1)...

Cystatin C (CysC), a cysteine protease inhibitor, has been widely proven to be a highly sensitive biomarker to predict the kidney function. The similarity of the renal and cerebral small vessels has awakened a surge of studies suggesting that CysC plays a key role in various cerebrovascular disorders. This review focuses on four major mechanisms of CysC in a variety of cerebrovascular diseases. (1)The property of the CysC Leu-68-Gln (L68Q) variant to aggregate and the property of the wild type CysC protein to co-aggregate with Amyloid-β (Aβ); (2)The disruption of equilibrium between CysC and related cysteine proteases; (3)The function of CysC as an inflammatory inducing factor; (4)The ability of CysC to induce autophagy...

This study sought to identify sources of the reduced fertility of men with type 2 diabetes mellitus. Significant reductions in semen volume, sperm concentration, and total sperm count were observed in diabetic individuals, while transmission electron microscopy revealed that the structure of mitochondria in the tail of sperm from diabetic patients was damaged. Proteins potentially associated with these sperm defects were identified using proteomics. Isobaric tagging for relative and absolute quantitation labeling and high-performance liquid chromatography-tandem mass spectrometry allowed us to identify 357 proteins significantly differentially expressed in diabetic versus control semen (>1...

Glomerular filtration rate is the best quantitative marker of renal function. It allows diagnosis and classification of severe chronic kidney disease into five stages. Theoretically, the measurement of glomerular filtration rate is based on the calculation of urinary clearance of exogenous substances such as chromium 51-labeled inulin or ethylenediaminetetraacetic acid ([(51)Cr]-EDTA). In practice, glomerular filtration rate is most often estimated from equations derived from plasma creatinine. This article reviews the range of methods used to measure or approximate glomerular filtration rate and attempts to describe recent developments in this area, including those related to plasma creatinine assay methods, creatinine and cystatin C concentration-derived estimations...

Several mammalian proteins form pathological deposits under nonphysiological conditions that are associated with many degenerative diseases. Protein aggregation is associated with aging, as well as a variety of diseases, including cystic fibrosis, amyotrophic lateral sclerosis (ALS), and hypertrophic cardiomyopathy. There is a lack of any potential anti-amyloidogenic agents and therapeutics till date. Polyphenols have been accredited with myriad biological effects. An analysis of the effects of natural agents like baicalin (BC) and gallocatechin (GC) on aggregation process can open new avenues for the treatment of protein misfolding diseases...

Parasitic nematodes have evolved powerful immunomodulatory molecules to enable their survival in immunocompetent hosts by subverting immune responses and minimizing pathological processes. One filarial molecule known to counteract host immune responses by inducing IL-10 and regulatory macrophages in mice is filarial cystatin. During a patent filarial infection monocytes encounter microfilariae in the blood, an event that occurs in asymptomatically infected filariasis patients that are immunologically hyporeactive...

Fibroblast growth factor 23 (FGF23) is an independent risk factor for cardiovascular mortality in chronic kidney disease. Omega-3 (n-3) fatty acid consumption has been inversely associated with FGF23 levels and with cardiovascular risk. We examined the effect of marine n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and plant-derived alpha-linolenic acid (ALA) on plasma FGF23 levels in post-myocardial infarction patients with chronic kidney disease. In the randomized double-blind Alpha Omega Trial, 4837 patients with a history of myocardial infarction aged 60-80 years (81% men) were randomized to one of four trial margarines supplemented with a targeted additional intake of 400 mg/day EPA and DHA, 2 g/day ALA, EPA-DHA plus ALA, or placebo for 41 months...
