The Production, Efficacy, and Safety of Machine-Generated Bicarbonate Solution for Continuous Venovenous Hemodialysis (CVVHD): The Cleveland Clinic Method.

Rationale & Objective: Since 1994, the Nephrology and Hypertension Department at the Cleveland Clinic has prepared and used bicarbonate-based solution for continuous venovenous hemodialysis (CVVHD) using a standard volumetric hemodialysis machine rather than purchasing from a commercial vendor. This report describes the process of producing Cleveland Clinic UltraPure Solution (CCUPS), quality and safety monitoring, economic costs, and clinical outcomes.

Study Design: Retrospective study.

Molecular breath analysis identifies the breathprint of renal failure.

Many uremic solutes retained in chronic kidney disease are volatile, and can be detected by breath testing. We compared the exhaled breath of subjects with end stage renal disease (ESRD) to healthy volunteers to identify volatile compounds that can serve as a potential breathprint for renal failure. We analyzed the exhaled breath of 86 ESRD subjects and 25 healthy volunteers using selected-ion flow-tube mass spectrometry (SIFT-MS).

Patency and Complications of Translumbar Dialysis Catheters.

Translumbar tunneled dialysis catheter (TLDC) is a temporary dialysis access for patients exhausted traditional access for dialysis. While few small studies reported successes with TLDC, additional studies are warranted to understand the short- and long-term patency and safety of TLDC. We conducted a retrospective analysis of adult patients who received TLDC for hemodialysis access from June 2006 to June 2013.

Subacute polyneuropathy in a patient undergoing peritoneal dialysis: clinical features and new pathophysiologic insights.

Recently, demyelinating polyneuropathies have been reported in end-stage renal disease patients. These acute and subacute neuropathies share a demyelinating feature and may develop after the initiation of continuous ambulatory peritoneal dialysis. The pathogenesis of these non-chronic forms of neuropathy remains unclear.

Spontaneous perinephric hematoma due to acquired factor X deficiency in AL amyloidosis.

Spontaneous perinephric hematoma (SPH) is a rare entity whose diagnosis is challenging because of its varied clinical presentation and lack of any specific etiology. We report a 34-year-old African-American male who presented with left flank pain and was found to have a large left perinephric hematoma, in the setting of undiagnosed AL amylodosis. The case illustrates that while a SPH due to the vascular angiopathy of amyloid is rare, when amyloidosis is associated with abnormal coagulation studies or bleeding at multiple sites, it should be considered because of its protean systemic manifestations and potential response to chemotherapy.
