Microcirculation impairment and related vasculopathy is a hallmark of systemic sclerosis. Digital ulcers are second only to Raynaud's phenomenon as a vascular complication occurring in scleroderma patients. Digital ulcers are painful and generate disability. Furthermore, patients may develop recurrent digital ulcers and one may ask whether the outcomes of such patients might be different to those of unaffected ones. Recently several registries have provided relevant information about digital ulcers. Male sex and severe skin disease seem to be the main associated factors observed in several registries...

BK polyomavirus mostly manifests as polyomavirus-associated nephropathy (PyVAN) in kidney transplant patients and polyoma virus-associated hemorrhagic cystitis (PyVHC) in bone marrow transplant patients. PyVHC in kidney transplant patients is only reported in four cases in the literature. Our patient had severe hemorrhagic cystitis without renal involvement. We postulate that our patient's exposure to ifosfamide and radiation 8 years prior transplantation might pre-dispose him to this disease. This article is protected by copyright...

One factor that significantly contributes to renal allograft loss is chronic calcineurin inhibitor (CNI) nephrotoxicity (CIN). Among other factors, the complement (C-) system has been proposed to be involved CIN development. Hence, we investigated the impact of CNIs on intracellular signalling and the effects on the C-system in human renal tubule cells. In a qPCR array, CNI treatment upregulated C-factors and downregulated SOCS-3 and the complement inhibitors CD46 and CD55. Additionally, ERK1/-2 was required for these regulations...

Introduction: Extracorporeal circuit (EC) anticoagulation with heparin is a key advance in hemodialysis (HD), but anticoagulation is problematic in inpatients at risk of bleeding. We prospectively evaluated a heparin-avoidance HD protocol, clotting of the EC circuit (CEC), impact on dialysis efficiency, and associated risk factors in our acute care inpatients who required HD (January 17, 2014 to May 31, 2015). Methods: HD sessions without routine EC heparin were performed using airless dialysis tubing...

Cold storage is the most prevalent method for graft preservation in kidney transplantation (KTX). The protective effects of various preservation solutions have been extensively studied in both clinical trials and experimental animal models. However, a paucity of studies examined the effect of different preservation solutions on graft function in mouse KTX, in addition, the tolerance of the transplanted grafts to further insult has not been evaluated, which were the objectives of the present study. We performed mouse KTX in three groups with the donor kidneys preserved in different solutions for 60 minutes: saline, mouse serum, and University of Wisconsin (UW) solution...

The endeavor to study desensitization in kidney transplantation hasn't been matched by an effort to investigate strategies to prevent sensitization. In this study (NCT02437422), we investigated the safety, impact on sensitization and pharmacokinetics of SANGUINATE (SG), a hemoglobin-based oxygen carrier, as a potential alternative to packed red blood cells (PRBC) in transplant candidates with end-stage renal disease (ESRD). Ten ESRD subjects meeting inclusion/exclusion (I/E) criteria were planned to receive 3 weekly infusions of SG (320mg/Kg)...

Hemodialysis (HD) patients are at high risk for all-cause mortality and cardiovascular events. In addition to traditional risk factors, excessive oxidative stress (OS) and chronic inflammation emerge as novel and major contributors to accelerated atherosclerosis and elevated mortality. OS is defined as the imbalance between antioxidant defense mechanisms and oxidant products, the latter overwhelming the former. OS appears in early stages of chronic kidney disease (CKD), advances along with worsening of renal failure, and is further exacerbated by the HD process per se...

In crystallopathies, crystals or crystalline particles of environmental and metabolic origin deposit within tissues, induce inflammation, injury and cell death and eventually lead to organ-failure. The NLRP3-inflammasome is involved in mediating crystalline particles-induced inflammation, but pathways leading to cell death are still unknown. Here, we have used broad range of intrinsic and extrinsic crystal- or crystalline particle-sizes and shapes, e.g. calcium phosphate, silica, titanium dioxide, cholesterol, calcium oxalate, and monosodium urate...

GLP-1-based treatment improves glycemia through stimulation of insulin secretion and inhibition of glucagon secretion. Recently, more and more findings showed that GLP-1 could also protect kidney from diabetic nephropathy. Most of these studies focused on glomeruli, but the effect of GLP-1 on tubulointerstitial and tubule is not clear yet. In this study, we examined the renoprotective effect of recombinant human GLP-1 (rhGLP-1), and investigated the influence of GLP-1 on inflammation and tubulointerstitial injury using diabetic nephropathy rats model of STZ-induced...

Lepidium apetalum Willd has been used to reduce edema and promote urination. Cis-desulfoglucotropaeolin (cis-DG) and trans-desulfoglucotropaeolin (trans-DG) were isolated from Lepidium apetalum Willd, and caused a significant increase in cell viability in a hypertonic model in NRK52e cells. In the hypertonic model, cis-DG and trans-DG significantly promoted the cell viability of NRK52e cells and inhibited the elevation of Na⁺ in the supernatant, inhibited the renin-angiotensin-aldosterone (RAAS) system, significantly reduced the levels of angiotensin II (Ang II) and aldosterone (ALD), and lowered aquaporin-2 (AQP2) and Na⁺-K⁺ ATP content in renal medulla...

Renal ischemic and reperfusion injury resulting in acute renal failure is a multidisciplinary problem at the junction of pathophysiology, transplantology, urology, nephrology, cardiac surgery and pharmacology. One of renal protection strategies is using the phenomenon of preconditioning. Preconditioning is one of the ways to adopt a tissue to repeated short-term effects of damaging factors to induce an enhanced tolerance to the long period of hypoxia and/or ischemia. There are multiple cellular and molecular mechanisms of the renal protective effects of preconditioning stimuli, but the key effectors and signaling molecules are ATP-dependent potassium channels, nitric oxide synthase, nitric oxide, and mitochondrial pore...

Population pharmacokinetic (popPK) modeling was used to characterize the PK profile of the oral janus kinase (JAK)1/JAK2 inhibitor, baricitinib, in 18 patients with Mendelian interferonopathies who are enrolled in a compassionate use program. Patients received doses between 0.1 to 17 mg per day. Covariates of weight and renal function significantly influenced volume-of-distribution and clearance respectively. The half-life of baricitinib in patients less than 40kg was substantially shorter than in adult populations, requiring the need for dosing up to 4 times daily...
