Hematopoietic stem cell transplantation is a curative treatment for many hematologic malignancies with its most important side effect being graft-versus-host disease (GVHD). Herein, we present a 3.5 year-old male with weight of 9.8 kg with acute GVHD (grade IV gastrointestinal and cutaneous) who did not respond to the first line therapies (corticosteroids). Thus, the patient was a candidate for extracorporeal photochemotherapy (ECP). Due to the hyperbilirubinemia, two sessions of ECP every week as well as one session of plasmapheresis 24 h before each ECP session were performed (Spectra™ Optia® apheresis system)...

Hemolytic uremic syndrome caused by Shiga toxin-producing E. coli (STEC-HUS) is often associated with a severe morbidity including neurological involvement and a mortality of 1-5%. Although STEC-HUS is often self-limited, improvement of treatment strategies is needed for cases with complications and, among others, plasma exchange/plasmapheresis and use of antibiotics have been advocated. With the availability of the complement blocker eculizumab, now a standard treatment of atypical HUS, several series have addressed its use in STEC-HUS, with variable response; randomized controlled trials are lacking...

Renal and neurological involvements are frequently seen in thrombotic thrombocytopenic purpura (TTP). Cardiac involvement, however, has been rarely reported. In this article, we present 2 cases of myocardial infarction in patients with TTP. In the first case, a young man presented with non-ST-segment elevation myocardial infarction that resolved promptly with plasmapheresis. The second patient developed ST-segment elevation myocardial infarction early in the course of the disease and died before plasmapheresis could be initiated...

Malignant hypertension can cause thrombotic microangiopathy (TMA) characterized by hemolytic anemia and thrombocytopenia. On the other hand, severe hypertension is sometimes associated with hemolytic uremic syndrome (HUS) or thrombotic thrombocytopenic purpura (TTP). Distinguishing these entities is important because of therapeutic implications. Plasmapheresis should be initiated as soon as possible if we are dealing with TTP. We describe the case of a 30-year-old man referred to our hospital with malignant hypertension, severe renal failure and TMA: haemoglobin=9g/dL, total bilirubin=0...

INTRODUCTION: Donor-specific alloantibodies (DSAs) cause kidney-allograft loss in chronic antibody-mediated rejection (CAMR). Treatment relies on blocking antibody-producing cells and removing DSAs by apheresis: e.g., double-filtration plasmapheresis (DFPP). MATERIALS AND METHODS: To determine the impact of DFPP (6 or 8 sessions/patient) on clotting factors and natural anticoagulants, and on thrombin generation, we performed a prospective and observational study in five CAMR kidney-transplant patients who received DFPP plus rituximab therapy...

PURPOSE OF REVIEW: There is increasing recognition of the importance of antibody-mediated rejection (AMR) after lung transplantation. The development of donor-specific antibodies, a key feature of AMR, occurs in approximately 30% of lung transplant recipients and is associated with poor posttransplant outcomes. This review highlights recently developed AMR diagnostic criteria in lung transplantation, potential mechanisms that mediate the development of AMR, and discusses current and emerging treatment strategies for this significant, graft-limiting complication...

Hydralazine is a direct-acting vasodilator, which has been used in treatment for hypertension (HTN) since the 1950s. While it is well known to cause drug-induced lupus (DIL), recent reports are indicating the emergence of the drug-induced anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (DIV). Herein, we describe two patients (aged 57 and 87 years) who presented with severe acute kidney injury (AKI), proteinuria, and hematuria. Both were receiving hydralazine for the treatment of hypertension...

Treatment of chronic hepatitis B (CHB) patients with nucleos(t)ide analogues (NA) suppresses HBV DNA synthesis but does not affect synthesis of HBV pregenomic RNA (pgRNA). HBV pgRNA is detectable in the serum during NA treatment and has been proposed as a marker of HBV covalently closed circular DNA (cccDNA) activity within the infected hepatocyte. We developed an automated assay for the quantification of serum HBV pgRNA using a dual-target qRT-PCR approach on the Abbott m2000sp/rt system. We demonstrate accurate detection and quantification of serum HBV RNA...

BACKGROUND: Desensitization for ABO-incompatible (ABOi) kidney transplantation mainly comprises removal of antibodies with the use of apheresis and suppression of antibody (Ab) production with the use of rituximab. This study aimed to estimate the outcomes of ABOi kidney transplantation with the use of an Ab removal-free protocol to avoid complications associated with apheresis. METHODS: A total of 32 de novo consecutive adults who underwent ABOi living-donor kidney transplantation were retrospectively evaluated...

INTRODUCTION: To investigate the correlation between serum anti-ABO immunoglobulin G (IgG) and IgG subclasses, anti-ABO IgG subclasses were measured by flow cytometry (FCM) in ABO-incompatible (ABOi) kidney transplant recipients. We also evaluated baseline anti-ABO C1q antibody. METHOD: Baseline anti-ABO IgG titers were measured by both FCM and column agglutination technique methods in 18 ABOi kidney transplant recipients. The mean florescence intensity (MFI) ratios of baseline anti-ABO IgG subclasses and anti-ABO C1q antibody were obtained by FCM and followed-up after rituximab treatment, each plasmapheresis (PP) session, and kidney transplantation...

BACKGROUND: Monoclonal gammopathy causes several kinds of renal pathology. A rare and special form is monoclonal gammopathy-induced C3 glomerulopathy (MG-C3G). Like idiopathic C3G, MG-C3G frequently leads to end-stage renal disease. MG-C3G frequently recurs after renal transplantation, leading to graft failure in most of the patients. While there is some evidence for successful treatment of recurrent idiopathic C3 glomerulopathy with eculizumab after renal transplantation, nothing is known about its efficacy in the setting of recurrent MG-C3G...

This retrospective study presents our 4-year experience of preemptive treatment of early anti-HLA donor specific antibodies with IgA- and IgM-enriched immunoglobulins. We compared outcomes between patients with antibodies and treatment (case patients) and patients without antibodies (control patients). Records of patients transplanted at our institution between 03/2013 and 11/2017 were reviewed. The treatment protocol included one single 2g/kg immunoglobulin infusion followed by successive 0.5g/kg infusions for a maximum of 6 months, usually combined with a single dose of anti-CD20 antibody and, in case of clinical rejection or positive crossmatch, with plasmapheresis or immunoabsorption...

Atypical hemolytic uremic syndrome (aHUS) is characterized by uncontrolled complement activation leading to thrombotic microangiopathy and severe end-organ damage. The most common trigger for an episode of aHUS in the background of genetic deregulation of the alternative complement pathway is systemic infection. There are only 4 reported cases of aHUS triggered by influenza B thus far. Current accepted therapies for aHUS include plasma exchange and eculizumab. We describe a unique patient with aHUS with a rare membrane cofactor protein mutation triggered by influenza B infection, who achieved complete remission with treatment with high-dose corticosteroids after failure of plasmapheresis...

BACKGROUND/AIMS: Middle East respiratory syndrome coronavirus (MERS-CoV) and Marburg virus (MARV) are among the World Health Organization's top 8 emerging pathogens. Both zoonoses share nonspecific early symptoms, a high lethality rate, and a reduced number of specific treatment options. Therefore, we evaluated extracorporeal virus and glycoprotein (GP) elimination by lectin affinity plasmapheresis (LAP). METHODS: For both MERS-CoV (pseudovirus) as well as MARV (GPs), 4 LAP devices (Mini Hemopurifiers, Aethlon Medical, San Diego, CA, USA) and 4 negative controls were tested...
