Microvascular inflammation in kidney transplants: finally an effective treatment?

Microvascular inflammation-glomerulitis and peritubular capillaritis-is the hallmark histologic lesion of antibody-mediated allograft rejection and may also occur in the absence of donor-specific antibodies.

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.
