Human parietal epithelial cells as Trojan horses in albumin overload.

Parietal Epithelial Cells (PECs) activation and proliferation are common to several distinct forms of glomerulopathies. Due to several stimuli, PECs can change to a progenitor (CD24 and CD133/2) or a pro-sclerotic (CD44) phenotype. In addition, PECs, which are constantly exposed to filtered albumin, are known to be involved in albumin internalization, but how this mechanism occurs is unknown.

The Long-Term Treatment of Drug-Resistant Migraine with the Modified Atkins Ketogenic Diet: A Single-Center, Retrospective Study.

Despite advances in pharmacological therapies, migraine patients are often drug resistant. Further therapeutic options in this field are, therefore, desirable. Recent studies have highlighted the efficacy of ketogenic diet (KD) on improving migraine, but data on their long-term efficacy and safety are lacking.

Exploring Chronic Pain in Hemodialysis Patients: An Observational Study Based on the New IASP Classification for ICD-11.

Introduction: Pain is one of the most frequently reported symptoms in hemodialyzed (HD) patients, with prevalence rates between 33% and 82%. Risk factors for chronic pain in HD patients are older age, long-lasting dialysis history, several concomitant diseases, malnutrition, and others. However, chronic pain assessment in HD patients is rarely performed by specialists in pain medicine, with relevant consequences in terms of diagnostic and treatment accuracy.

Peritoneal Catheters Malposition/Dysfunction and Their Approach with Catheterography and Radiologic Manipulation in Peritoneal Dialysis: A Minireview and Case Series.

Peritoneal catheter dysfunction is one of the most frequent complications of peritoneal dialysis. The malposition of a peritoneal catheter may cause one- or two-way obstruction with fluid outflow or inflow problems, large residual volumes, and, therefore, reduced ultrafiltration and sometimes abdominal pain. Standard procedures may often fail to solve the dysfunction.

Glucose-Free Solutions Mediated Inhibition of Oxidative Stress and Oxidative Stress-Related Damages in Peritoneal Dialysis: A Promising Solution.

Oxidative stress (OxSt) and inflammation are common in end-stage renal disease and dialysis patients; they are known risk factors for cardiovascular disease and mortality. In peritoneal dialysis (PD), OxSt and inflammation are even further increased compared to the already increased oxidative stress of their pre-dialysis phase. This is due to the high glucose-based solutions currently used, whose continuous contact with the peritoneal membrane can induce significant long-term morphological and functional changes (mesothelial to mesenchymal transition, thickening, neo-angiogenesis and fibrosis) of the peritoneal membrane.

The Quality of Life in Elderly Patients in Comprehensive Conservative Management or Hemodialysis: A Case-Control Study in Analogous Basal Conditions.

Background/objectives: Comprehensive conservative management (CCM) is a viable treatment option for elderly patients with end-stage kidney disease (ESKD). However, it involves a significant change in dietary habits, such as adopting a low-protein diet. Therefore, it is crucial to understand its impact on the patient's quality of life (QoL), particularly when compared to hemodialysis (HD).

The Rationale for Combining Normothermic Liver Machine Perfusion with Continuous Renal Replacement Therapy to Maintain Physiological Perfusate during Ex Vivo Organ Perfusion.

The possibility of keeping liver grafts viable and functioning until transplantation has been explored since the 1950s. However, the current modalities of Normothermic Machine Perfusion (NMP) have shown several limitations, such as the inability to correct electrolytes and pH derangements efficiently. Combining NMP with continuous kidney replacement therapy (CKRT) might provide a promising new model to overcome these issues.

The Role of Daily Dialysate Calcium Exposure in Phosphaturic Hormones in Dialysis Patients.

Managing mineral bone disease (MBD) could reduce cardiovascular risk and improve the survival of dialysis patients. Our study focuses on the impact of calcium bath exposure in dialysis patients by comparing peritoneal dialysis patients (PD, intervention group) and hemodialysis patients (HD, control group). We assessed various factors, including calcium, phosphorus, magnesium, PTH, vitamin D 25-OH, C-terminal telopeptide (CTX), and FGF-23 levels, as well as the calcium bath six hours before the blood sample and the length of daily calcium exposure.

The Impact of Legalizing Medical Aid in Dying on Patient Trust: A Randomized Controlled Survey Study.

Some commentators and several professional medical associations have expressed concern that legalizing medical aid in dying ("MAID") will undermine patient trust in the medical profession, particularly among historically disadvantaged patient populations. While this concern remains influential, it has been subject to limited empirical scrutiny. This study aims to empirically assess whether MAID legalization undermines patient trust, with considerations of potential trust/demographic correlations in marginalized and minority patient populations.

Targeting CD25+ lymphoma cells with the antibody-drug conjugate camidanlumab tesirine as a single agent or in combination with targeted agents.

Camidanlumab tesirine (ADCT-301) is a CD25-specific antibody-drug conjugate (ADC) employing SG3199, a highly cytotoxic DNA minor groove cross-linking pyrrolobenzodiazepine dimer. The ADC has shown early clinical antitumour activity in various cancers, including B- and T-cell lymphomas. We assessed its preclinical activity as a single agent in 57 lymphoma cell lines and in combination with selected drugs in T-cell lymphoma-derived cell lines.

Oxidative stress and its role in Fabry disease.

Fabry disease is a rare X-linked disease characterized by deficient expression and activity of alpha-galactosidase A with consequent lysosomal accumulation of glycosphingolipids, particularly globotriaosylceramide in various organs. Currently, enzyme replacement therapy with recombinant human α-galactosidase is the cornerstone of the treatment of Fabry patients, although in the long term enzyme replacement therapy fails to halt disease progression, in particular in case of late diagnosis. This suggests that the adverse outcomes cannot be justified by the lysosomal accumulation of glycosphingolipids alone, and that additional therapies targeted at further pathophysiologic mechanisms might contribute to halting the progression of cardiac, cerebrovascular and kidney disease in Fabry patients.

Oxidative stress reduction by icodextrin-based glucose-free solutions in peritoneal dialysis: Support for new promising approaches.

Background: Oxidative stress (OxSt) and inflammation are common in CKD and are known CV and mortality risk factors. In peritoneal dialysis (PD) OxSt and Inflammation even increase due to the use of glucose-based solutions.

Patients And Methods: This study analyzed in 15 PD patients the effect of 3 and 6 months of treatment with icodextrin-based glucose-free solutions on OxSt and inflammation, evaluating p22 protein expression (Western blot), NADPH oxidase subunit, essential for OxSt activation, MYPT-1 phosphorylation state, marker of RhoA/Rho kinase pathway (ROCK) activity, involved in the induction of OxSt (Western blot) and Malondialdehyde (MDA) production (fluorimetric assay).

Low-Protein Diet in Elderly Patients with Chronic Kidney Disease Stage 4 and 5 in Conservative Management: Focus on Sarcopenia Development.

Introduction: Chronic kidney disease is a degenerative and increasingly prevalent condition that includes metabolic abnormalities and is associated with a higher risk of sarcopenia. The conservative approach points primarily to controlling metabolic issues and reducing the risk of malnutrition and sarcopenia, slowing the progression of kidney disease. The present study aims to evaluate the effect of a low-protein diet on malnutrition and sarcopenia.

Targeting CD19-positive lymphomas with the antibodydrug conjugate loncastuximab tesirine: preclinical evidence of activity as a single agent and in combination therapy.

Antibody-drug conjugates (ADC) represent one of the most successful therapeutic approaches introduced into clinical practice in the last few years. Loncastuximab tesirine (ADCT-402) is a CD19-targeting ADC in which the antibody is conjugated through a protease cleavable dipeptide linker to a pyrrolobenzodiazepine dimer warhead (SG3199). Based on the results of a phase II study, loncastuximab tesirine was recently approved for adult patients with relapsed/refractory large B-cell lymphoma.

"Every Cloud Has a Silver Lining": How Three Rare Diseases Defend Themselves from COVID-19 and What We Have Learnt from It.

The process of SARS-CoV-2 infection, responsible for the COVID-19 pandemic, is carried out through different steps, with the interaction between ACE2 and Spike protein (S) being crucial. Besides of that, the acidic environment of endosomes seems to play a relevant role in the virus uptake into cells and its intracellular replication. Patients affected by two rare genetic tubulopathies, Gitelman's and Bartter's Syndromes, and a rare genetic metabolic disease, Fabry Disease, have shown intrinsic protection from SARS-CoV-2 infection and COVID-19 on account of specific intrinsic features that interfere with the virus uptake into cells and its intracellular replication, which will be reported and discussed in this paper, providing interesting insights for present and future research.

EBV Reactivation in Transplant Recipients following SARS-CoV-2 Infection: A Retrospective Study.

Reactivation and primary infection with a high Epstein Barr Virus (EBV) DNA level in kidney transplant patients could cause severe complications, including the development of Post-Transplantation Lymphoproliferative Disease (PTLD). While in the general population the reactivation of EBV after SARS-CoV-2 infection has been reported, very few data are available in transplant recipients. Our retrospective study aimed to evaluate a possible EBV reactivation in kidney transplant patients following SARS-CoV-2 infection and a possible impairment of the immune system.

The RAAS Goodfellas in Cardiovascular System.

In the last two decades, the study of the renin-angiotensin-aldosterone system (RAAS) has revealed a counterregulatory protective axis. This protective arm is characterized by ACE2/Ang 1-7/MasR and Ang 1-9 that largely counteracts the classic arm of the RAAS mediated by ACE/Ang II/AT1R/aldosterone and plays an important role in the prevention of inflammation, oxidative stress, hypertension, and cardiovascular remodeling. A growing body of evidence suggests that enhancement of this counterregulatory arm of RAAS represents an important therapeutic approach to facing cardiovascular comorbidities.

Safety of Citrate Anticoagulation in CKRT: Monocentric Experience of a Dynamic Protocol of Calcium Monitoring.

Regional Citrate Anticoagulation (RCA) is considered the first-line anticoagulation for Continuous Kidney Replacement Therapy (CKRT). The RCA requires strict protocols and trained staff to avoid unsafe use and ensure its benefit. We have analyzed all our CKRT prescriptions from December 2020 to April 2022 anonymously, collecting data on CKRT, lab tests, clinical conditions, and complications of RCA.

Efficacy and tolerability of oral morphine versus oxycodone/acetaminophen for analgesia in the emergency department.

Objective: Oxycodone/acetaminophen is one of the most commonly prescribed medications for pain management in the emergency department (ED) despite its high abuse liability. Our objective was to determine whether oral immediate-release morphine is as effective and well tolerated as oral oxycodone/acetaminophen for pain relief in stable ED patients.

Design: This is a prospective comparative study in which stable adult patients with acute painful conditions who had either oral morphine (15 or 30 mg) or oxycodone/acetaminophen (5/325 mg or 10/650 mg) ordered for them at the discretion of a triage physician were recruited.
