When I got my US driving license, I was asked whether or not I would like to be an organ donor. To me, having seen the positive effects of donation on the lives of my patients down through…
We have previously discussed cardiovascular mortality after transplantation. But one controversial aspect in the evaluation of potential kidney recipients is the performance of stress tests for risk stratification. With the cost of stress tests ranging from U$2,500-5,000 and the…
It is surprising how high the nonadherence rates for immunosuppressants is among renal transplant recipients, ranging from 15 to 40%, despite the potential impact of nonadherence and the degree of education provided to transplant recipients. Nonadherence to immunosuppressive…
In the quest for better solute clearance, two divergent paths were taken on each side of the Atlantic. The US nephrology community has concentrated more on low weight molecules. The European counterpart has focused on both low and…
Can you have an acidosis with normal serum bicarbonate? Of course you can, it’s just incomplete. Incomplete distal renal tubular acidosis (idRTA) that is. RTA was first described in 1935, confirmed as a renal tubular disorder in 1946,…
I was reviewing the treatment of diabetes insipidus the other day, and was reminded of the paradoxical effect of thiazide diuretics on urine output in diabetes insipidus. How does this work? The traditional thinking is that thiazide-induced blockade…
How familiar are the following scenarios to you? You’re in clinic and have just seen a 69 year old man with a longstanding history of hypertension. He has been referred by his internist to nephrology for an eGFR…
In a previous post, we discussed the way the cilastatin prevents imipenem nephrotoxicity by inhibiting dihydropeptidase, a proximal tubular brush border enzyme which facilitates the uptake of imipenem metabolites into proximal tubular cells. This allows imipenem to be…
One of the issues that we come across repeatedly in the clinic is the timing of access insertion. We all want to avoid the use of catheters and so we refer patients early (when possible) for fistula formation….
Diabetes is a common cause of CKD and the prevalence of diabetic nephropathy is increasing. A question that sometimes arises in the clinic is when it is appropriate to biopsy a patient with a presumptive diagnosis of diabetic…
