Community-acquired acute kidney injury in India: data from ISN-acute kidney injury registry.

Background: Acute kidney injury (AKI), particularly community-acquired AKI (CA-AKI), is a major health concern globally. The International Society of Nephrology's "0 by 25" initiative to reduce preventable deaths from AKI to zero by 2025 is not achievable in low and middle income countries, such as India, possibly due to a lack of data and measures to tackle this urgent public health issue. In India, CA-AKI predisposes younger patients to hospitalization, morbidity, and mortality.

Ferroptosis and pyroptosis signatures in critical COVID-19 patients.

Critical COVID-19 patients admitted to the intensive care unit (ICU) frequently suffer from severe multiple organ dysfunction with underlying widespread cell death. Ferroptosis and pyroptosis are two detrimental forms of regulated cell death that could constitute new therapeutic targets. We enrolled 120 critical COVID-19 patients in a two-center prospective cohort study to monitor systemic markers of ferroptosis, iron dyshomeostasis, pyroptosis, pneumocyte cell death and cell damage on the first three consecutive days after ICU admission.

Role of short-dwell daily ethanol-lock therapy in the management of hemodialysis tunneled cuffed catheter-related bloodstream infection.

Background: Catheter-Related Blood Stream Infection (CRBSI) is the major limitation of using Tunneled cuffed catheter (TCC) for long-term Hemodialysis. The standard therapy of CRBSI involves systemic antibiotics with catheter replacement/removal. As antibiotic alone is rarely effective therapy for CRBSI, biofilm eradication using antimicrobial locking solutions is a promising modality for CRBSI treatment, hence catheter salvage.

Targeting ferroptosis protects against experimental (multi)organ dysfunction and death.

The most common cause of death in the intensive care unit (ICU) is the development of multiorgan dysfunction syndrome (MODS). Besides life-supporting treatments, no cure exists, and its mechanisms are still poorly understood. Catalytic iron is associated with ICU mortality and is known to cause free radical-mediated cellular toxicity.

Adult-onset nephrotic syndrome following coronavirus disease vaccination.

A 22-year-old healthy man was admitted for oedema 15 days after the first injection of the COVISHIELD coronavirus disease 2019 (COVID-19) vaccine (Oxford AstraZeneca) vaccine. Nephrotic syndrome was diagnosed and a kidney biopsy showed minimal change disease. Oral prednisolone was started at 1 mg/kg/day resulting in complete remission within 1 week.

Chronic Kidney Disease of Unknown Etiology in India: What Do We Know and Where We Need to Go.

Chronic kidney disease (CKD) not associated with known risk factors has been reported from parts of India and is presumed to be similar to CKD of unknown etiology (CKDu) that has been described from Central America. The reports from India have been fragmented without clear description of the disease phenotype or its determinants. This paper summarizes the current state of knowledge around CKDu in India based on a review of literature, multi-stakeholder consultation, and a survey of Indian nephrologists.

Increased serum catalytic iron may mediate tissue injury and death in patients with COVID-19.

The pathophysiology and the factors determining disease severity in COVID-19 are not yet clear, with current data indicating a possible role of altered iron metabolism. Previous studies of iron parameters in COVID-19 are cross-sectional and have not studied catalytic iron, the biologically most active form of iron. The study was done to determine the role of catalytic iron in the adverse outcomes in COVID-19.

Kidney Transplantation with ABO-Incompatible Donors: A Comparison with Matched ABO Compatible Donor Transplants.

Introduction: ABO-incompatible kidney transplantation (ABOiKTx) expands the living donor pool. There is limited long-term outcome data from India especially in comparison with ABO-compatible kidney transplantation (ABOcKTx). Here we report outcomes of the first 100 ABOiKTx compared to ABOcKTx from our center.

Serum catalytic iron and progression of chronic kidney disease: findings from the ICKD study.

The Adverse Effect of COVID Pandemic on the Care of Patients With Kidney Diseases in India.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has affected the care of patients with noncommunicable diseases, including those suffering from kidney-related ailments. Many parts of the world, including India, adopted lockdown to curb community transmission of disease. The lockdown affected transportation, access to health care facilities, and availability of medicines and consumables as well as outpatient and inpatient services.

Iron, Hepcidin, and Death in Human AKI.

Background: Iron is a key mediator of AKI in animal models, but data on circulating iron parameters in human AKI are limited.

Methods: We examined results from the ARF Trial Network study to assess the association of plasma catalytic iron, total iron, transferrin, ferritin, free hemoglobin, and hepcidin with 60-day mortality. Participants included critically ill patients with AKI requiring RRT who were enrolled in the study.

Catalytic iron in acute myocardial infarction complicated by cardiogenic shock - A biomarker substudy of the IABP-SHOCK II-trial.

Background: Catalytic iron (CI) is unbound ferric iron with the potential to generate reactive oxygen species with further deleterious vascular effects. In acute coronary syndromes, high levels of CI are linked to all-cause mortality. The prognostic impact of CI and iron metabolism in cardiogenic shock (CS) is currently undetermined.

Lack of electron microscopy hinders correct renal biopsy diagnosis: A study from India.

Electron microscopy (EM) is performed routinely on all native kidney biopsies in the western world. However, in India, it is not regularly performed due to non-availability and financial constraints. The aim of this prospective study was to evaluate the usefulness of routinely performing EM on native kidney biopsies.

Increased plasma catalytic iron in patients may mediate acute kidney injury and death following cardiac surgery.

Catalytic iron, the chemical form of iron capable of participating in redox cycling, is a key mediator of acute kidney injury (AKI) in multiple animal models, but its role in human AKI has not been studied. Here we tested in a prospective cohort of 250 patients undergoing cardiac surgery whether plasma catalytic iron levels are elevated and associated with the composite outcome of AKI requiring renal replacement therapy or in-hospital mortality. Plasma catalytic iron, free hemoglobin, and other iron parameters were measured preoperatively, at the end of cardiopulmonary bypass, and on postoperative days 1 and 3.

Recent advances in understanding the pathogenesis of atherosclerosis in CKD patients.

A need exists for developing new therapies to improve cardiovascular outcomes in end-stage kidney disease. Three new areas that address novel pathophysiological mechanisms and/or therapeutic approaches toward cardiovascular events in chronic kidney disease patients include the use of an anti-inflammatory agent, the role of catalytic iron, and protein carbamylation. In preliminary studies, hydroxychloroquine, which has multiple anti-inflammatory properties, preserved vascular compliance for the aorta and major vessels, as well as reduced the extent of severity of atherosclerosis in ApoE-/- mice.
