Full house immunostaining does not always mean lupus nephritis. Young man initially diagnosed with lupus MN, but proved with mass spec to be syphilis-associated MN

🔬 Spiculated intratubular casts on silver stain, Congo red positivity, and apple-green birefringence point to amyloid cast nephropathy. Paraffin IF confirmed kappa restriction despite negative routine IF.

Interesting finding of large multi-nucleated endothelial cells in a txp biopsy with chronic active AMR. IHC stain is ERG (endothelial cell marker). Probably just a manifestation of chronic endothelial cell injury in this setting #renalpath #pathtwitter #nephrology

左室肥大と腎障害が並んだとき、糖尿病や高血圧、肥大型心筋症だけで説明しきれないことがあります。今回の症例報告は、Fabry病とMGRSが同時に見つかった、初めての報告です。

読みどころは、ひとつの診断名で全体像をまとめすぎない姿勢です。MGRSは腎生検なしには見逃されやすく、Fabry病も典型的な皮膚症状や神経痛を欠くlate-onset型では、心筋症として扱われ続けることがあります。特に原因不明の左室肥大に蛋白尿、腎機能低下、M蛋白が重なる場合、アミロイドーシスだけでなく、Fabry病やMGRSを含めて考える必要があります。

Sex, menopause and CKD in primary care

🧐Women are protected before midlife, but this advantage disappears beyond age 50 years. Seems CKD works like atherosclerosis/CVD

Diabetic Nephropathy (DN) with concurrent primary podocytopathy represents a distinct clinical entity characterized by nephrotic-range proteinuria, ultrastructural podocyte effacement and favorable response to immunosuppressive therapy ca. 2026 from @NDTsocial
