BACKGROUND: Administration of an anticoagulant during therapeutic plasma exchange (TPE) is necessary to avoid circuit clotting and impaired treatment effectiveness. Citrate is the preferred anticoagulant for apheresis worldwide, and unfractionated heparin (UH) is the second most preferred, yet there are only a few published studies regarding the use of UH during TPE. There are even fewer studies regarding the use of low-molecular-weight heparin (LMWH) and TPE performed without anticoagulation...

PURPOSE: Data for ANCA-associated vasculitis (AAV) patients requiring intensive care are scarce. METHODS: We included 97 consecutive patients with acute AAV manifestations (new onset or relapsing disease), admitted to 18 intensive care units (ICUs) over a 10-year period (2002-2012). A group of 95 consecutive AAV patients with new onset or relapsing disease, admitted to two nephrology departments with acute vasculitis manifestations, constituted the control group...

Plasma exchange is a non-selective apheresis technique that can be performed by filtration or centrifugation allowing rapid purification of high molecular weight pathogens. An immunosuppressive treatment is generally associated to reduce the rebound effect of the purified substance. Substitution solutes such as human albumin and macromolecules are needed to compensate for plasma extraction. Compensation by viro-attenuated plasma is reserved solely for the treatment of thrombotic microangiopathies or when there is a risk of bleeding, because this product is very allergenic and expensive...

Since the mid 1970s, when membrane modules became available, plasma separation techniques have gained in importance especially in the past few years. The advantages of this method are a complete separation of the corpuscular components from the plasma and due to increased blood flow rate and higher efficacy. Systemic autoimmune diseases based on an immune pathogenesis produce autoantibodies and circulating immune complexes, which cause inflammation in the tissues of various organs. In most cases, these diseases have a poor prognosis without treatment...

The process of curing a patient by removing his illness by extracting blood is a very old one. Many years ago, phlebotomy was practiced to cure illness. Now, this old process, placed on a rational basis with therapeutic apheresis (TA), is being followed in clinical practice. Therapeutic plasma exchange (TPE) with hollow fiber modules has been used in different severe diseases for more than 40 years. Based on many years of experience with the extracorporeal circulation in end-stage renal disease, the authors herein give an overview of TA in immunological diseases, especially in hematologic, autoimmune and dermatologic diseases...

Nearly 50% of patients with multiple myeloma develop renal disease, most commonly from AKI caused by cast nephropathy. Development of AKI is associated with poor 1-year survival and reduces the therapeutic options available to patients. There is a great need for more effective therapies. Cast nephropathy is caused by the interaction and aggregation of filtered free light chains and Tamm-Horsfall protein causing intratubular obstruction and damage. The key to treating cast nephropathy is rapid lowering of free light chains, because this correlates with renal recovery...

We report a patient treated with rituximab for interstitial pneumonia (IP) associated with microscopic polyangiitis (MPA) and who was undergoing hemodialysis. A 59-year-old woman who had been treated with tacrolimus for 1 year for rheumatic arthritis was referred to the Department of Nephrology for fatigue, fever, weight loss, and rapidly developing renal dysfunction. On the first admission, severe renal dysfunction, proteinuria, hematuria, and an elevated titer of MPO-ANCA were observed, and the woman was diagnosed with rapidly progressive glomerulonephritis because of MPA...

INTRODUCTION: Gemcitabine-induced thrombotic microangiopathy is a rare event whose management is not yet consensual. The use of eculizumab could be of interest. CASE REPORT: A 68-year-old woman was treated by gemcitabine as adjuvant chemotherapy of a pancreatic adenocarcinoma. Two months later, the patient presented with mechanical hemolytic anemia, thrombocytopenia and high blood pressure that led to the diagnosis of thrombotic microangiopathy. Gemcitabine was stopped...

Therapeutic plasma exchange (TPE) is an extracorporeal blood purification technique designed for the removal of substances with large molecular weight from the plasma. However, it is not commonly performed in children and the elderly because of concern of potential complications. The Department of Nephrology at Zagreb University Hospital Centre's database (8335 procedures, 981 patients) was retrospectively analyzed from 1982 to 2011 to record indications, applications, and safety of TPE use in children (≤18 years), adults (>18 and <65 years), and elderly patients (≥65 years)...

Plasmapheresis also known as a therapeutic plasma exchange (TPE) is a procedure of plasma removal with it's ineligible plasma's component. Usually it is a supportive measure used simultaneously with the treatment, but in a few diseases, e.g. in trombotictrombocytopenic purpura (TTP), it is a first-choice treatment. During the plasmapheresis plasma is mostly replaced by 20% solution of albumin or combination of 20% solution of albumin and 0.9% solution of NaCl, however in some diseases fresh frozen plasma (FFP) is used...

Fluids play an important role in clinical nephrology.1) Temperature of dialysate fluid has recently re-attracted a lot of attention. Individualized cooling of the dialysate (0.5 °C below predialysis ear temperature) has been shown to not only prevent intradialytic hypotension but also to improve myocardial contractility and to prevent white matter changes in CKD5D.2) Access fluid in AKI is associated with an increased mortality. While Furosemide has no place in treating AKI the Furosemide stress test can help to identify patients with AKI that will eventually need renal replacement therapy...

Therapeutic plasma exchange (TPE) is a well-established treatment modality for nephrology patients, using two conventional methods: membrane (mTPE) or centrifugal TPE (cTPE). Although the efficacy of both treatments has been described, there are few reports that compare these methodologies. Here we describe three nephrology patients who were treated with both mTPE and cTPE. The mTPE method, but not the cTPE method, was associated with persistent difficulty anticoagulating the extracorporeal circuit in all three patients...

Therapeutic apheresis (TA) refers to a group of extracorporeal blood treatment modalities with clinical indications for which the clinicians' knowledge, availability and applicability vary widely worldwide. Therapeutic plasma exchange (TPE), the most common TA technique, is neither readily available nor affordable in many parts of Africa. This article focuses on the challenges of starting a TPE program in a resource-constrained economy and the result of a survey of Nigerian nephrology professionals on TPE. A critical appraisal of published manuscripts from Nigeria on TA was undertaken to assess uses, methods, and challenges encountered followed by a survey of the perceptions of Nigerian nephrology professionals on TPE...
