AI Article Synopsis
- The study investigates the unknown causes of calcium oxalate crystal deposits in the hearts of hemodialysis patients.
- A rise in plasma oxalate levels or ionized calcium did not lead to crystal deposits, suggesting these factors alone aren't the cause.
- Crystal deposits were notably increased in heart transplants that underwent rejection, implying that local tissue condition plays a vital role in crystal deposition.
Article Abstract
Although the deposition of calcium oxalate crystals in the myocardium can be associated with significant morbidity and mortality in hemodialysis patients, the pathogenesis of this deposition is not known. The present study was undertaken in order to clarify the contributing factors in an experimental setting. A simple increase in plasma oxalate levels did not cause deposits in the heart, nor did elevated values of plasma ionized calcium appear to be important in chronic renal failure. Following heterotopic cardiac transplantation, a much larger deposition of crystals was identified in the heart allograft that was histologically damaged by rejection. These findings suggest that the state of the local tissue is a very important factor in the deposition of oxalate crystals.

Background: Regionally anticoagulated continuous renal replacement therapy with citrate is the first choice for critically ill patients with acute kidney injury. If citrate that reaches the patient exceeds the metabolic capacity, metabolic alkalosis will follow. Bicarbonate from the treatment fluids will also reach the patient and add to the bicarbonate load.

Background: In an Italian cohort of lupus podocytopathy patients, we aimed to characterize the presenting features, therapy, and outcomes, and explore differences between relapsing and non-relapsing patients.
Methods: We identified 29 patients with lupus podocytopathy from 1994 to 2023 in 11 Italian Nephrology/Rheumatology Units, and divided them into two groups: relapsing and non-relapsing. Given the limited sample size, a p-value ≤ 0.
The impact of a secondary, rare, non-pathogenic PKD1 variant on disease progression in autosomal dominant polycystic kidney disease.

Department of Nephrology, Beaumont Hospital, Dublin, Ireland.
Background: Autosomal dominant polycystic kidney disease (ADPKD) is caused primarily by pathogenic variants in the PKD1 and PKD2 genes. Although the type of ADPKD variant can influence disease severity, rare, hypomorphic PKD1 variants have also been reported to modify disease severity or cause biallelic ADPKD. This study examines whether rare, additional, potentially protein-altering, non-pathogenic PKD1 variants contribute to ADPKD phenotypic outcomes.

Mineralocorticoid receptor antagonists (MRAs) are a cornerstone of guideline-directed medical therapy for heart failure with reduced ejection fraction (HFrEF), offering significant benefits in reducing mortality and hospitalizations. However, their use is often constrained by the risk of hyperkalemia, particularly in patients with chronic kidney disease. Patiromer and sodium zirconium cyclosilicate (SZC), two novel potassium binders, have emerged as highly effective and safe tools for managing hyperkalemia and enabling the optimization of MRA therapy.

Background: It remains unclear whether physicians should accept transplantation offers for candidates with a positive SARS-CoV-2 reverse transcription polymerase chain reaction test due to the potential risk of severe infection after initiating immunosuppressive therapy.
Methods: A multicenter observational study was conducted in 19 French solid organ transplantation units. Patients on the waiting list for liver or kidney transplants who had a positive SARS-CoV-2 reverse transcription polymerase chain reaction nasopharyngeal swab at the time of transplantation were recorded.
