Interferons are cytokines which play a central role in the inflammatory response, and commercially prepared interferons have proven useful in the treatment of several diseases. For instance, interferon-alpha (often used in conjunction with ribavirin) is often used in…
As acute rejection rates continue to fall, causes of late allograft loss, such as transplant glomerulopathy (TG), become increasingly important. TG should spring to mind when you encounter a renal transplant recipient who develops heavy proteinuria and progressive…
Although the majority of membranous nephropathy falls under the “idiopathic” category, there are a variety of causes of secondary membranous nephropathy. It is quite important to eliminate these entities as possible diagnoses, as the treatment for secondary membranous…
One of the largest controversies in the field of proteinuria/nephrotic syndrome research derives from a 2007 Kidney International paper published by Russo et al. Briefly stated, the authors suggest the paradigm-shifting idea that the glomerulus filters massive amounts…
A landmark paper on membranous nephropathy was published by Beck et al in the most recent issue of NEJM. Ultimately we will have to see if the finding is reproducible, but based on the data presented this represents…
Plasma oncotic pressure is important to prevent edema, right? And you would think that albumin, which plays a critical role in the binding of multiple plasma proteins and ionized calcium, is essential to life, right? The rare, autosomal…
I recently had to look up the differential diagnosis of nodular glomerulosclerosis: we had recently sent a clinic patient to undergo a renal biopsy based on a history of nephrotic-range proteinuria (urine protein to creatinine ratio of about…
Clinical trials evaluating the efficacy of various therapies of membranous nephropathy is a tricky business, given the natural history of the disease: because about 1/3 of patients spontaneously remit, it is often difficult to say that a patient’s…
Heard a case this morning regarding an elderly white patient who presented with nephrotic syndrome and minimal hematuria. After going through the extensive differential diagnosis, focusing largely on the likely candidates (membranous nephropathy and minimal change disease), the…
Renal vein thrombosis is a thrombotic occlusion of one or both renal veins. Its most common cause is nephrotic syndrome, which is a hypercoaguable state though to be due at least in part to loss of the anticoagulant…
