CD28null and Regulatory T Cells Are Substantially Disrupted in Patients with End-Stage Renal Disease Due to Diabetes Mellitus.

Int J Mol Sci 2021 Mar 15;22(6). Epub 2021 Mar 15.

Department of Nephrology, Aristotle University of Thessaloniki, Hippokration Hospital, 56442 Thessaloniki, Greece.

Background: End-stage renal disease (ESRD) is associated with alterations in T-cell immunity, including increased CD28null and reduced regulatory T cells (Tregs). However, whether immune disturbances are due to ESRD or primary disease is not yet clear. As diabetes mellitus is the leading cause of ESRD, we evaluated its impact on the immune profile of ESRD patients. Read More

J Clin Med 2021 Mar 15;10(6). Epub 2021 Mar 15.

The Bar-Ilan University Azrieli Faculty of Medicine, Safed 1311502, Israel.

Corona virus disease 2019 (COVID-19) imposes a serious public health pandemic affecting the whole world, as it is spreading exponentially. Besides its high infectivity, SARS-CoV-2 causes multiple serious derangements, where the most prominent is severe acute respiratory syndrome as well as multiple organ dysfunction including heart and kidney injury. While the deleterious impact of SARS-CoV-2 on pulmonary and cardiac systems have attracted remarkable attention, the adverse effects of this virus on the renal system is still underestimated.

Analyzing the Long Time-Scale Dynamics of Uremic Toxins Bound to Sudlow Site II in Human Serum Albumin.

J Phys Chem B 2021 03 15;125(11):2910-2920. Epub 2021 Mar 15.

Department of Chemistry, University of Washington, Seattle, Washington 98195-1700, United States.

Protein bound uremic toxins (PBUTs), a series of chemicals that remain a challenge for removal strategies used on patients suffering with chronic kidney disease, could be strong candidates for MD study in order to better understand the interactions and time scales associated with binding mode transitions. Currently, traditional dialysis methods cannot satisfactorily remove PBUTs from the bloodstream. This is at least partly due to these toxin's high level of affinity for protein binding sites, particularly the prominent human serum albumin (HSA) and two of its drug binding sites (Sudlow site I and II).

Ketoanalogue supplements reduce mortality in patients with pre-dialysis advanced diabetic kidney disease: A nationwide population-based study.

Clin Nutr 2021 Feb 6. Epub 2021 Feb 6.

Chang Gung University College of Medicine, Taoyuan, Taiwan; Division of Nephrology, Department of Internal Medicine, Keelung Chang Gung Memorial Hospital, Keelung, Taiwan; Graduate Institute of Clinical Medicine, College of Medicine, National Taiwan University, Taipei, Taiwan; Community Medicine Research Center, Keelung Chang Gung Memorial Hospital, Keelung, Taiwan. Electronic address:

Background & Aims: Metabolism dysregulation and protein energy wasting occur in patients with chronic kidney disease (CKD) and are associated with poor survival, especially in patients prior to starting dialysis. Accumulating evidence indicates that dietary supplementation with ketoanalogues (KAs, a mixture of branched-chain amino acids) exerts a variety of beneficial effects for patients with CKD. However, the role of KAs in diabetic kidney disease (DKD), one of the major causes of CKD, is still controversial. Read More

Serum Total Bilirubin and Progression of Chronic Kidney Disease and Mortality: A Systematic Review and Meta-Analysis.

Front Med (Lausanne) 2020 25;7:549. Epub 2021 Jan 25.

Department of Nephrology, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.

Previous studies have suggested that serum total bilirubin (STB) levels are associated with heightened chronic kidney disease (CKD) and mortality in both the general population and nephropathy patients. However, these results remain inconsistent. The aim of our study was to investigate whether STB was a predictor for progression of CKD and mortality by meta-analysis. Read More

Host fibrinogen drives antimicrobial function in peritonitis through bacterial-mediated prothrombin activation.

Proc Natl Acad Sci U S A 2021 01 21;118(1). Epub 2020 Dec 21.

Department of Pathology and Laboratory Medicine, Lineberger Comprehensive Cancer Center, and the UNC Blood Research Center, University of North Carolina, Chapel Hill, NC 27599;

The blood-clotting protein fibrinogen has been implicated in host defense following infection, but precise mechanisms of host protection and pathogen clearance remain undefined. Peritonitis caused by staphylococci species is a complication for patients with cirrhosis, indwelling catheters, or undergoing peritoneal dialysis. Here, we sought to characterize possible mechanisms of fibrin(ogen)-mediated antimicrobial responses. Read More

Lipohypertrophy in Elderly Insulin-Treated Patients With Type 2 Diabetes.

Diabetes Ther 2021 Jan 21;12(1):107-119. Epub 2020 Nov 21.

Diabetes, Endocrinology and Metabotic Disease, IRCCS San Raffaele Pisana, Rome, Italy.

Background: The number of older adults with insulin-treated diabetes mellitus (DM) is steadily increasing worldwide. Errors in the insulin injection technique can lead to skin lipohypertrophy (LH), which is the accumulation of fat cells and fibrin in the subcutaneous tissue. While lipohypertrophic lesions/nodules (LHs) due to incorrect insulin injection techniques are very common, they are often flat and hardly visible and thus require thorough deep palpation examination and ultrasonography (US) for detection.

M Girndt

Nephrologe 2020 Jul 16:1-10. Epub 2020 Jul 16.

Klinik für Innere Medizin II, Nephrologie, Rheumatologie, Endokrinologie, Martin-Luther-Universität Halle-Wittenberg, Ernst-Grube-Str. 40, 06120 Halle/Saale, Deutschland.

Patients with chronic kidney diseases are particularly at risk of infections and must therefore be protected against the risks of infection in dialysis treatment. Viral hepatitis no longer plays a very prominent role in dialysis facilities because nosocomial transmission can be reliably avoided. Nowadays, patients colonized with multidrug-resistant bacteria, including methicillin-resistant (MRSA), multidrug-resistant gram-negative bacteria or vancomycin-resistant enterococci, are more common.

Department of Internal Medicine, Division of Nephrology and Transplantation, Erasmus MC, University Medical Center, 3015 GD Rotterdam, The Netherlands.

With expanding kidney transplantation programs, remaining hemodialysis patients are more likely to have a high comorbidity burden and may therefore be more prone to lose muscle mass. Our aim was to analyze risk factors for muscle loss in hemodialysis patients with high comorbidity. Fifty-four chronic hemodialysis patients (Charlson Comorbidity Index 9. Read More

Premature aging of circulating T cells predicts all-cause mortality in hemodialysis patients.

BMC Nephrol 2020 07 13;21(1):271. Epub 2020 Jul 13.

Department of Nephrology, Zhongshan Hospital, Fudan University, NO180, Feng'lin Road, Xuhui District, Shanghai, 200032, P.R. China.

Background: Patients with end-stage renal disease (ESRD) exhibit a premature aging phenotype of immune system, which is recently concerned as a significant factor for increased risk of various morbidities. Nevertheless, there are few dates explicating the relevancy of T cell senescence to mortality. In this study, we prospectively studied the predictive value of T cell senescence for mortality in hemodialysis patients. Read More

Genetic Deletion of Vasohibin-2 Exacerbates Ischemia-Reperfusion-Induced Acute Kidney Injury.

Int J Mol Sci 2020 Jun 26;21(12). Epub 2020 Jun 26.

Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama 7008558, Japan.

Acute kidney injury (AKI) has been increasingly recognized as a risk factor for transition to chronic kidney disease.

Pneumonia-induced endothelial amyloids reduce dendritic spine density in brain neurons.

Sci Rep 2020 06 9;10(1):9327. Epub 2020 Jun 9.

Departments of Physiology and Cell Biology, Mobile, Alabama, 36688, USA.

Pseudomonas aeruginosa pneumonia elicits endothelial cell release of cytotoxic amyloids that can be recovered from the bronchoalveolar lavage and cerebrospinal fluids of critically ill patients. Introduction of these cytotoxic amyloids into the lateral ventricle impairs learning and memory in mice. However, it is unclear whether the amyloids of lung origin (1) are neurotropic, and (2) cause structural remodeling of hippocampal dendrites. Read More
