Real-World Observation

3/5

These findings offer insights into the mechanisms of renal involvement and highlight the complex, context-dependent role of macrophages in clearance and tissue injury.

What Changes?

Nephrology · Clinical Practice

Current Standard

Conventional nephrology practice relies on standard-of-care monitoring and existing regimens prior to this clinical evidence review.

New Finding

Rauf et al. demonstrate that macrophage infiltration in kidney biopsies portends progression to renal replacement therapy despite hematologic response, whereas regression on serum P component scintigraphy independently predicts favorable outcomes.

Gut-targeted interventions to complement PTH-lowering therapy

These findings highlight the potential of gut-targeted interventions to complement established parathyroid hormone-lowering strategies for improving skeletal health. Secondary hyperparathyroidism is a major contributor to skeletal fragility in chronic kidney disease, yet fracture risk remains high despite parathyroid hormone-lowering therapy.

Fingerprinting the polycystic kidney: radiomics of the noncystic parenchyma for earlier ADPKD detection

Small, cross-sectional, unmatched data require longitudinal validation of reproducibility, prognostic value, and clinical utility. Autosomal dominant polycystic kidney disease risk stratification relies on total kidney volume, a validated marker of cyst burden and progression.

Kidney stone disease: to drink or not to drink-that is the question

Effective prevention likely requires achieving a substantial increase in urine volume alongside comprehensive dietary and pharmacologic management. An important point to note is that these findings do not invalidate the protective role of increased urine volume but highlight the limitations of behavioral interventions alone.
