Sixty-five echocardiograms were performed on 20 children with chronic renal failure and were compared with 101 normal controls. The main cardiac abnormalities were dilation of left ventricle and left atrium, left ventricular wall and septum hypertrophy, increase of cardiac output, and rarely decrease of contractility. Anemia, arteriovenous fistula, arterial hypertension and severe renal failure (patients treated by maintenance dialysis) were factors associated with these abnormalities. The authors emphasize the value of echocardiograms in the follow up of children with chronic renal failure.

The impact of a secondary, rare, non-pathogenic PKD1 variant on disease progression in autosomal dominant polycystic kidney disease.

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.

Autosomal dominant polycystic kidney disease (ADPKD) is a dominant genetic disorder caused primarily by mutations in the PKD1 gene, resulting in the formation of numerous cysts and eventually kidney failure. However, there are currently no gene therapy studies aimed at correcting PKD1 gene mutations. In this study, we identified two mutation sites associated with ADPKD, c.

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.

Hepatitis B virus (HBV) infection is a major global health concern, with liver transplantation (LT) serving as a critical treatment for end-stage liver disease caused by HBV. However, the risk of HBV reinfection after LT remains significant, necessitating effective prophylaxis. Today, the combination of hepatitis B immune globulin (HBIG) and high-barrier nucleos(t)ide analogues (NUCs) is the standard of care for preventing HBV recurrence post-LT but concerns about the cost of HBIG and access to high-barrier NUCs have led to a reduction in the use, dose, and duration of HBIG in recent years.

Recent studies suggest that empagliflozin may also reverse cardiac remodeling in heart failure by reducing N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels. In our study, we wanted to show the decrease in NT-proBNP levels, which is an indicator of poor prognosis in heart failure, and to see if there was a decrease in the rate of renal progression in patients with HF after empagliflozin use.
