Age-Related Macular Degeneration in Chronic Kidney Disease: A Meta-Analysis of Observational Studies
Conclusions: The overall results support a positive association between CKD and AMD, although some limitations exist. Given the risk that AMD is increased in CKD, regular eye screenings for the CKD population is recommended for an early detection and intervention.Am J Nephrol 2018;48:278 –291 (Source: American Journal of Nephrology)

Gut Microbial Product Predicts Cardiovascular Risk in Chronic Kidney Disease Patients.
This study examined the potential link between short chain fatty acids (SCFAs), which are produced by the gut microbiota, and cardiovascular outcomes in patients with CKD. METHODS: SCFAs were measured using a targeted liquid chromatography-mass spectrometry platform in baseline plasma samples from 214 patients with CKD enrolled in the Clinical Phenotyping Resource and Biobank Core; 81 patients with coronary artery disease (CAD) and 133 without CAD were randomly assigned to training and validation subsets. The primary outcome was a history of CAD and the secondary outcome was a composite history of cardiovascular disea...

Calciphylaxis is a disease of dermal arteriolar calcification that results in necrosis. It commonly occurs in individuals with end-stage renal disease (ESRD) on hemodialysis and is associated with a high morbidity and mortality. Warfarin use is an identified risk factor. Twenty patients with ESRD on dialysis with calciphylaxis who were treated with apixaban for indications of deep vein thrombosis or atrial fibrillation were identified. There were no reports of thrombosis. Three individuals experienced bleeding requiring a transfusion, and anticoagulation was resumed without further event. Findings suggest that apixaban may...

A Review of the Imaging Techniques for Measuring Kidney and Cyst Volume in Establishing Autosomal Dominant Polycystic Kidney Disease Progression
Background: Autosomal dominant polycystic kidney disease (ADPKD) is the commonest inherited renal disorder; it is defined by progressive renal cyst formation and subsequent renal enlargement that leads to end-stage renal disease. Until recently, only symptomatic treatments for ADPKD existed. However, therapies that address the underlying pathophysiology of ADPKD are now available and accurate identification of the rate of disease progression is essential.Summary: Published data on the different imaging modalities for measuring kidney and cyst volumes in ADPKD are reviewed. The advantages and drawbacks of the different tech...

Conclusions: ACEi/ARB therapy is associated with an increased risk of hyperkalemia in anuric hemodialysis patients. The proportion of patients with normal sK concentrations decreased from 82 to 29% and with mild hyperkalemia increased from 18 to 52%. Severe hyperkalemia necessitating the interruption of ACEi/ARB therapy developed in 19% of patients.
