Hypercoagulable state in severe nephrotic syndrome
- Patients with nephrotic syndrome have increased risk of thromboembolism, particularly deep vein and renal vein thrombosis
- Nephrotic syndromes (except for Minimal Change Disease) are characterized by non-selective proteinuria
- Possible that patients with significant proteinuria lose anticoagulant proteins in the urine
- Tendency to have VTE in nephrotic syndrome can correlate with degree of hypoalbuminemia

AKI in HIV-positive patients
- ATN and pre-renal states, similar to patient without HIV
- Medication nephrotoxicity secondary to ART (protease inhibitors, tenofovir) and medications used to treat opportunistic infections (antivirals, Bactrim, etc)
- HIV-associated thrombotic microangiopathy - more rare in the ART era
CKD in HIV-positive patients
- HIV associated nephropathy (HIVAN) - collapsing form of focal segmental glomerulosclerosis, presents with significant proteinuria and rapidly progressive kidney disease, not seen in those with normal CD 4 count and undetectable viral load
- Immune complex mediated glomeruonephritis - can be membranous nephropathy, membranoproliferative GN, and "lupus-like" proliferative GN
- Glomerulonephritis due to HCV co-infection
