Hospital Course:
• With Diagnosis of Acute on Chronic (pre-renal) patient was started on Lasix 40 Q day and Spironolactone 100 mg QD then Lasix 80 BID.
• U/O: 1000 cc/day (average)
• R IJ was placed and HD started.
Light microscopy (slides are not available)
2 glomeruli showing:• Moderately severe membrano-proliferative
changes:– Mesangial cell hyperplasia in axial regions of tufts– Swelling of podocytes and endothelial cells– Patchy thickening of glomerular basement membranes– Capillary lumina are narrowed
• Hypertrophy and hyperplasia of parietal epithelial cells
• Peri-glomerular fibrosis
IF
• IgG- Moderate to marked granular deposits.
• IgA- Trace amounts.
• IgM- Trace amounts.
• C- Moderate to marked granular deposits.
Original diagnosis (1974)Renal Biopsy:
• Membrano-proliferative glomerulonephritis,– Process is active– Most consistent with a diagnosis of immune-
complex induced GN
Upon review of EM pictures
• EM supports a diagnosis of post-infectious or membranous GN.
• Presence of numerous subepithelial deposits, somewhat more irregularly spaced than would be usual for membranous.
