BACKGROUND: Auto-immune thrombotic thrombocytopenic purpura (TTP) is a morbid multi-organ disorder. Cardiac involvement not recognized in initial disease descriptions is a major cause of morbidity. Therapeutic plasma exchange (TPE) requires exposure to multiple plasma donors with risk of transfusion-transmitted infection (TTI). Pathogen inactivation (PI) with amotosalen-UVA, the INTERCEPT Blood System for Plasma (IBSP) is licensed to reduce TTI risk. METHODS: An open-label, retrospective study evaluated the efficacy of quarantine plasma (QP) and IBSP in TTP and defined treatment emergent cardiac abnormalities...

OBJECTIVE: Liver failure (LF) is a clinically complex disorder that characterizes with hepatic dysfunction. This study aimed at observing the therapeutic effects of peritoneal dialysis on liver function in LF patients. PATIENTS AND METHODS: This study involves 62 patients diagnosed as LF hospitalized from February 2005 to December 2016. The 62 LF patients were randomly divided into 3 groups, including artificial liver applying plasma exchange group (PE, n = 28), peritoneal dialysis group (PD, n = 22), and conservative treatment group (CT, n=12)...

Renal involvement with rapidly progressive glomerulonephritis is a common manifestation of antineutrophil cytoplasmic antibody (ANCA) associated vasculitides, which is characterized by end-stage renal disease and high mortality rates in untreated and/or late referral patients. The long-term renal survival has improved dramatically since the addition of cyclophosphamide (CYC) and recently of rituximab (RTX) in association with corticosteroids in the remission induction therapeutic regimens. However, renal prognosis remains unfavorable for many patients and the mortality rate is still significantly high...

BACKGROUND: Hepatitis C virus (HCV)-associated mixed cryoglobulinaemia is the manifestation of an inflammation of small and medium-sized vessels produced by a pathogenic IgM with rheumatoid factor activity generated by an expansion of B-cells. The immune complexes formed precipitate mainly in the skin, joints, kidneys or peripheral nerve fibres. Current therapeutic approaches are aimed at elimination of HCV infection, removal of cryoglobulins and also of the B-cell clonal expansions. The optimal treatment for it has not been established...

Desensitisation with therapeutic plasma exchange (TPE) is essential for ABO-incompatible (ABO-I) liver transplants (LTs). However, excessive citrate load and coagulation disturbances after TPE have been poorly studied, in particular in cirrhotic patients with hypocapnic alkalosis, metabolic compensation and electrolyte imbalances. We retrospectively evaluated 1123 consecutive LT recipients (923 ABO-compatible [ABO-C], 200 ABO-I) from November 2008 to May 2015. TPE was generally performed a day before LT and blood sampling was performed before anaesthesia induction...

Objective: To emphasize the role of apheresis in management of pancreatitis. Methods: The clinical course of a patient admitted for hypertriglyceridemia-induced pancreatitis (HTGP) complicated by multiorgan dysfunction is described, who demonstrated dramatic improvement in his clinical status after total plasma exchange (TPE). In addition, the current guidelines for TPE and the alternative treatment options for HTGP are also presented. Results: A patient presenting with pancreatitis associated with severe systemic inflammatory response was admitted to our hospital with an initial triglyceride level of 1181 mg/dL...

Pure red cell aplasia (PRCS) is a well-recognized complication after allogeneic hematopoietic stem cell transplantation (HSCT). Many therapeutic options are available to treat this condition, including erythropoietin, rituximab, bortezomib, plasma exchange, immunoadsorption, donor lymphocyte infusion, mesenchymal stem cells, anti-thymocyte globulin and high-dose steroids; however treatment outcomes are often variable and can sometimes lead to disappointing results. In this brief article we report our experience with two patients with PRCA after major AB0-incompatible HSCT who were resistant to multiple therapeutic interventions and who eventually benefited from treatment with eltrombopag, a thrombopoietin mimetic approved by the Food and Drug Administration for the treatment of patients with immune thrombocytopenic purpura or severe aplastic anemia (SAA), refractory to immunosuppressive agents or not eligible to HSCT...

Guillain-Barré syndrome is the most common cause of acute flaccid paralysis worldwide. Microorganisms such as Campylobacter jejuni, Cytomegalovirus, Epstein-Barr virus, Mycoplasma pneumoniae, Haemophilus influenzae and Zika virus have been linked to the disease. The most common clinical variants are acute inflammatory demyelinating polyneuropathy and acute motor axonal neuropathy. Plasma exchange and intravenous immunoglobulins are the standard therapy for the disease. Areas covered: research to elucidate the pathophysiology of Guillain-Barré syndrome has led to the development of drugs directed towards new potential therapeutic targets...

Since the advent of extracorporeal membrane oxygenation (ECMO) over 40 years ago, there has been increasing interest in the use of the extracorporeal circuit as a platform for providing multiple organ support. In this review, we will examine the evidence for the use of continuous renal replacement therapy, therapeutic plasma exchange, leukopheresis, adsorptive therapies, and extracorporeal liver support in conjunction with ECMO.

The behavioral variant of frontotemporal dementia is usually a sporadic and progressive neurodegenerative disorder. Here, we report the subacute onset of a frontotemporal dementia phenotype with a treatable etiology. The patient has a history of rheumatoid arthritis, episcleritis, and thyroid eye disease on immunosuppressive therapy. He experienced a rapid personality change, including inappropriate behavior, which suggested frontotemporal dementia. Results of imaging and neuropsychological testing also suggested frontotemporal dementia...

Objective: Therapeutic plasma exchange (TPE) offers an alternative therapeutic modality for patients with systemic lupus erythematosus (SLE) and primary antiphospholipid syndrome (APS). However, there is conflicting evidence regarding its efficacy in different sub-phenotypes. This study aimed to investigate the main clinical characteristics and outcomes of patients with different phenotypes of SLE and APS treated with TPE at a tertiary care center. Methods: The database of the Blood and Apheresis Unit between 2001 and 2013 was screened for patients with SLE and primary APS...

OBJECTIVES: Standard intensive care treatment is inadequate to keep children with liver failure alive without catastrophic complications to ensure successful transplant, as accumulation of endogenous protein-bound toxins often lead to hepatic encephalopathy, hepatorenal syndrome, cardiovascular instability, and multiple organ failure. Given paucity of proven treatment modalities for liver failure, blood purification using different extracorporeal treatments as a bridge to transplantation is used, but studies evaluating the safety and efficacy of combination of these therapies, especially in pediatric liver failure, are lacking...

Various direct and indirect cellular interactions between multi-functional mesenchymal stroma/stem-like cells (MSC) and cancer cells contribute to increasing plasticity within the tumor tissue and its microenvironment. Direct and tight communication between MSC and cancer cells is based on membrane protein interactions and the exchange of large plasma membrane fragments also known as trogocytosis. An ultimate but rare direct interaction resumes in fusion of these two cellular partners resulting in the formation of new cancer hybrid cell populations...

OBJECTIVE: This case report investigates an unusual hCG result in a woman who is not pregnant. PATIENT AND METHODS: A 43-year-old woman was admitted for recurrence of thrombotic thrombocytopenic purpura (TTP) and therapeutic plasma exchange (TPE) was initiated. Prior to transitioning the patient from TPE to immunosuppressive therapy, a serum qualitative hCG test was performed and was positive. Several etiologies for elevated hCG were considered and investigated, including heterophile antibody interference, endogenous hCG from pituitary or malignancy, and exogenous hCG...
