ANCA-Associated Vasculitis - Refining Therapy with Plasma Exchange and Glucocorticoids.

Efficacy of albumin and compounded plasma for plasma exchange in acquired thrombotic thrombocytopenic purpura.

Thrombotic thrombocytopenic purpura (TTP) is a rare life-threatening thrombotic microangiopathy. Therapeutic plasma exchange (TPE) is the first-line treatment for TTP. In our institution, albumin plus plasma (fresh frozen plasma [FFP] and/or cryoprecipitate-reduced plasma [CRP]) has been used as replacement fluid since 2014. We aimed to evaluate the efficacy of albumin combined with plasma as TPE for TTP.

Plasma exchange as treatment for osmotic demyelination syndrome: Case report and review of current literature.

Osmotic demyelination syndrome (ODS) is characterized by widespread degeneration of myelin within the central nervous system and has no established treatment. A limited number of cases have reported positive outcomes with plasma exchange in the treatment of ODS associated with chronic alcohol abuse or liver transplantation. We report the case of a 23-year-old female presenting with ODS following rapid correction of hyponatremia, which was attributed to hypoalbuminemia, volume overload, and malnutrition seco...

Anabolic androgenic steroids exert a selective remodeling of the plasma lipidome that mirrors the decrease of the de novo lipogenesis in the liver.

The abuse of anabolic androgenic steroids (AASs) is a source of public concern because of their adverse effects. Supratherapeutic doses of AASs are known to be hepatotoxic and regulate the lipoproteins in plasma by modifying the metabolism of lipids in the liver, which is associated with metabolic diseases. However, the effect of AASs on the profile of lipids in plasma is unknown.

Hypocomplementemic urticarial vasculitis syndrome with gastrointestinal vasculitis and crescentic membranoproliferative glomerulonephritis without immune complex deposits.

Hypocomplementemic urticarial vasculitis syndrome (HUVS) is a small vessel vasculitis characterized by hypocomplementemia and urticaria-like exanthema. Some cases also display abdominal pain and membranoproliferative glomerulonephritis (MPGN) with immune complex deposits. We treated a case of HUVS with biopsy-proven gastrointestinal vasculitis and atypical histological findings in a kidney biopsy. The 36-year-old Japanese man, who was previously diagnosed with diffuse panbronchiolitis, visited our hospital ...

Therapeutic plasma exchange may adjust IL-6 and TGF-β signals in relapsed MS patients peripheral blood.

Effects of therapeutic plasma exchange (TPE) on immune cells and their cytokine production in MS, are unknown. Since interleukine-6 and tumor growth factor-β have critical roles in MS immunopathogenesis, the impacts of TPE on the expression of these cytokines and their receptors on the surface of CD4+ T lymphocytes, were investigated.

Replacing plasma membrane outer leaflet lipids with exogenous lipid without damaging membrane integrity.

We recently introduced a MαCD-based method to efficiently replace virtually the entire population of plasma membrane outer leaflet phospholipids and sphingolipids of cultured mammalian cells with exogenous lipids (Li et al, (2016) Proc. Natl. Acad. Sci USA 113:14025-14030). Here, we show if the lipid-to- MαCD ratio is too high or low, cells can round up and develop membrane leakiness. We found that this cell damage can be reversed/prevented if cells are allowed to recover from the exchange step by incubat...

A liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based assay to profile 20 plasma steroids in endocrine disorders.

Background Liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based assays are employed in more and more clinical laboratories to quantify steroids. The steroid quantification by LC-MS/MS shows great value in screening or diagnosing endocrine disorders; however, the number of functional steroids included in the LC-MS/MS methods is still limited. Methods Here, we describe the performance and validation of a 20-steroid plasma panel by LC-MS/MS. The panel included progestogens (including mineralocortico...

Therapeutic plasma exchange in thrombotic thrombocytopenic purpura.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disease related to the formation of microvascular thrombosis and subsequent organ failure. The disease is accompanied with microangiopathic haemolytic anaemia, consumptive thrombocytopenia and lies on a severe deficiency in ADAMTS13, the von Willebrand factor-cleaving protease. In the acquired, immune-mediated form, this deficiency is due to the production of autoantibodies directed against the enzyme. Therapeutic plasma exchange has been used ...

Plasma sCD36 as non-circadian marker of chronic circadian disturbance in shift workers.

Shift work induces chronic circadian disturbance, which might result in increased health risks, including cardio-metabolic diseases. Previously, we identified sCD36 as a potential non-circadian biomarker of chronic circadian disturbance in mice. The aim of the current study (n = 232 individuals) was to identify whether sCD36 measured in plasma can be used as a non-circadian marker of chronic circadian disturbance in humans, which would allow its use to measure the effects of interventions and monitoring in ...

Peripheral vascular access for therapeutic plasma exchange: A practical approach to increased utilization and selecting the most appropriate vascular access.

Therapeutic plasma exchange (TPE) is used in the treatment of many diseases. At present, peripheral vascular access (PVA) is an underutilized method of vascular access in TPE. It should be considered more frequently due its relatively low risk for adverse events, particularly infections.

Are student nurses ready for new technologies in mental health? Mixed-methods study.

Technical innovations such as ecological momentary assessment (EMA), machine learning (ML), computerized adaptive testing (CAT), Digital Phenotyping, Clinical Decision Support Systems (CDSS), Algorithms, and Biomarkers have caused a paradigm shift in psychiatric care. The aim of the present study was to explore how student nurses view this paradigm shift, by assessing the acceptability of smartphone-based EMA, CAT, and biosensor-based Digital Phenotyping. We also investigated the factors affecting this acce...

Pharmacological treatment other than corticosteroids, intravenous immunoglobulin and plasma exchange for Guillain-Barré syndrome.

Plasma exchange and intravenous immunoglobulin, but not corticosteroids, are beneficial in Guillain-Barré syndrome (GBS). The efficacy of other pharmacological agents is unknown. This review was first published in 2011 and previously updated in 2013, and 2016.

Successful treatment of anti-MDA5 antibody-positive refractory interstitial lung disease with plasma exchange therapy.

We examined the effectiveness of plasma exchange (PE) therapy to reduce the mortality of rapidly progressive interstitial lung disease (RP-ILD) in patients positive for anti-melanoma differentiation-associated gene 5 (MDA5) antibodies.

Nuclear magnetic resonance investigation of water transport through the plasma membrane of various yeast species.

A specific technique of nuclear magnetic resonance (NMR) spectroscopy, filter-exchange spectroscopy (FEXSY), was employed to investigate water transport through the plasma membrane in intact yeast cells. This technique allows water transport to be monitored directly, thus avoiding the necessity to subject the cells to any rapid change in the external conditions, e.g. osmotic shock. We established a sample preparation protocol, a data analysis procedure and verified the applicability of FEXSY experiments. We...

Urticarial vasculitis and deep venous thrombosis following administration of intravenous cocaine.

Cocaine is associated with cardiac events, arterial dissections, strokes, and diverse types of vasculitis , including urticarial vasculitis. Cocaine-associated deep venous thrombosis (DVT) has been scarcely described. Here we describe the case of an intravenous cocaine user who developed an urticarial vasculitis and a thrombosis of the inferior vena cava.

Therapeutic plasma exchange for exogenous insulin antibody syndrome in combined variable immunodeficiency: a case report.

A 32-year-old male with type I diabetes presented with profound hypoglycemia due to exogenous insulin antibody syndrome in the setting of newly-diagnosed common variable immunodeficiency. Immunomodulatory therapy was not initially effective, but after the initiation of plasma exchange hypoglycemia resolved, and glucose lability improved.

Echocardiographic and biomarker evidence of plasma volume expansion after short-term steroids administered orally in cats.

Steroids administered PO and intramuscularly are associated with development of congestive heart failure in cats without prior signs of heart disease, but criteria to identify cats at increased risk for steroid-induced heart failure are not established.

Harnessing cell-free DNA: plasma circulating tumour DNA for liquid biopsy in genitourinary cancers.

In the era of precision oncology, liquid biopsy techniques, especially the use of plasma circulating tumour DNA (ctDNA) analysis, represent a paradigm shift in the use of genomic biomarkers with considerable implications for clinical practice. Compared with tissue-based tumour DNA analysis, plasma ctDNA is more convenient to test, more readily accessible, faster to obtain and less invasive, minimizing procedure-related risks and offering the opportunity to perform serial monitoring. Additionally, genomic pr...

Protein spectrum changes in exosomes after therapeutic plasma exchange in patients with neuromyelitis optica.

Neuromyelitis optica (NMO) is an autoimmune disease with a high rate of blindness and positive for the detection of aquaporin-4 antibody (AQP4) in most patients. NMO acute attacks are managed by high-doses of intravenous methylprednisolone followed by oral taper, and if symptoms fail to resolve, therapeutic plasma exchange (TPE) is added. TPE can remove pathological antibodies and inflammatory factors leading to clinical improvement.

Hidradenitis suppurativa and vasculitis: A case series and literature review of a rare association.

Hidradenitis suppurativa is a chronic inflammatory skin disease with dysregulation of the immune system. Its pathophysiology is not clear, and it has been reported in association with various inflammatory disorders such as pyoderma gangrenosum, arthritis, familial Mediterranean fever and inflammatory bowel diseases. However, the co-existence of HS and vasculitis is exceptional and has not been investigated. We report on five patients with vasculitis that are followed in our centers: one with Takayasu's arte...
