Iatrogenic Hypothermia during Hemodialysis Can Induce Serious Cardiac Arrhythmias in Diabetic Patient.

Saudi J Kidney Dis Transpl 2021 Jul-Aug;32(4):1146-1151

Department of Internal Medicine, Nephrology Division, King Fahd Hospital of the University, Al Khobar, Saudi Arabia.

Cardiovascular diseases are the main cause of morbidity and mortality in end-stage renal disease (ESRD) patients. Cardiac arrhythmias are prevalent in patients undergoing hemodialysis (HD), however, dialysis treatment per se can be considered as an arrhythmogenic stimulus. Uremic patients are characterized by a "pro-arrhythmic substrate" because of the high prevalence of ischemic heart disease, left ventricular hypertrophy, and autonomic neuropathy. Read More

Unravelling the pathophysiology of chronic kidney disease-associated pruritus.

Clin Kidney J 2021 Dec 24;14(Suppl 3):i23-i31. Epub 2021 Dec 24.

Department of Internal Medicine, Division of Nephrology, Hypertension and Autoimmune Disorders, Alb-Fils Kliniken, Göppingen, Germany.

For decades, itch related to chronic kidney disease (CKDaP) has been a clinical problem, but the aetiology and pathophysiology of CKDaP are still not yet fully understood-currently the underlying pathophysiological mechanisms are thought to be multifactorial. As new therapeutic targets have recently been identified and clinical trials have shown promising results, our current understanding of the interrelationships has expanded significantly. Here we review the pathophysiology and recent findings on modulation and sensitization of itch contributing to the development of CKDaP, covering hypothesis regarding immune system dysfunction, metabolic changes, uremic toxin deposition, peripheral neuropathy and imbalances in the endogenous opioid system.

Inhibition of O-GlcNAcylation protects from Shiga toxin-mediated cell injury and lethality in host.

EMBO Mol Med 2022 01 29;14(1):e14678. Epub 2021 Nov 29.

Infectious Disease Research Center, Korea Research Institute of Bioscience & Biotechnology (KRIBB), Daejeon, Korea.

Shiga toxins (Stxs) produced by enterohemorrhagic Escherichia coli (EHEC) are the major virulence factors responsible for hemorrhagic colitis, which can lead to life-threatening systemic complications including acute renal failure (hemolytic uremic syndrome) and neuropathy. Here, we report that O-GlcNAcylation, a type of post-translational modification, was acutely increased upon induction of endoplasmic reticulum (ER) stress in host cells by Stxs. Suppression of the abnormal Stx-mediated increase in O-GlcNAcylation effectively inhibited apoptotic and inflammatory responses in Stx-susceptible cells. Read More
