Biotherapy represents an innovative therapeutic approach that includes immunotherapy (vaccines, apheresis, and antibodies); gene therapy; and stem cell transplants. Their development helps to cross the bridge from bench to bedside and brings new hope of a cure for severe diseases in different fields of medicine. In neurology, a growing range of applications is being developed for these medications. Valuable results are now available in the field of autoimmunity, neuro-oncology, paraneoplastic manifestations, and neurodegenerative disorders...

In 1984, we started using therapeutic plasmapheresis (plasma exchange) as a method of extracorporeal lipoprotein elimination for the treatment of hypercholesterolemic patients. We evaluated the results of long-term therapy in 14 patients, 8 men and 6 women. The average age was 55.6+/-13.2 (range 28-70), median 59.5 years. 14 patients were diagnosed with familial hypercholesterolemia (FH): 5 homozygous, 9 heterozygous. Ten patients in the group were treated using immunoadsorption lipoprotein apheresis and 4 using hemorheopheresis...

INTRODUCTION: Therapeutic plasma exchange (TPE) is used for temporary support of liver function in patients presenting with early graft dysfunction after liver transplantation (LT) or liver surgery. We analyzed the effect of therapeutic apheresis on patients with liver disease. METHODS: Between January 2011 and August 2016, 93 apheresis procedures were performed for 26 patients at our institution. Anti-ABO isoagglutination immunoglobulin (Ig) M titer was checked using a type A and type B 3% red blood cell (RBC) suspension in saline with two-fold serial dilutions of patient serum...

BACKGROUND: At present, guidelines are lacking on platelet transfusion in patients with a traumatic intracranial bleed and history of antiplatelet therapy. The aspirin and P2Y 12 response unit (ARU and PRU, respectively) assays detect the effect of aspirin and P2Y 12 inhibitors in the cardiac population. OBJECTIVE: To describe the reversal of platelet inhibition after platelet transfusion using the ARU and PRU assays in patients with traumatic brain injury. METHODS: Between 2010 and 2015, we conducted a prospective comparative cohort study of patients presenting with a positive head computed tomography and a history of antiplatelet therapy...

In the mid-1990s, the days of lipoprotein(a) [Lp(a)] were numbered and many people would not have placed a bet on this lipid particle making it to the next century. However, genetic studies brought Lp(a) back to the front-stage after a Mendelian randomization approach used for the first time provided strong support for a causal role of high Lp(a) concentrations in cardiovascular disease and later also for aortic valve stenosis. This encouraged the use of therapeutic interventions to lower Lp(a) as well numerous drug developments, although these approaches mainly targeted LDL cholesterol, while the Lp(a)-lowering effect was only a 'side-effect'...

Thyroid storm or severe thyrotoxicosis results from extreme thyroid hormone elevation. Therapy includes medical management to prevent hormone production, release, recycling, and peripheral conversion while stabilizing adrenergic tone. Thyroid dysfunction is the usual cause but it can be due to excessive thyroid hormone ingestion. Therapeutic plasma exchange (TPE) has been used to rapidly remove protein-bound thyroid hormone. American Society for Apheresis guidelines make a weak recommendation to perform TPE in selected patients in the treatment of thyrotoxicosis based on low quality evidence...

Familial hypercholesterolemia (FH) is an autosomal dominant disorder due to mutation of apolipoprotein-B receptor gene causing severe dyslipidemia. Lifestyle modification and medical treatment attenuate the disease progression, but as these fail to control the blood cholesterol levels, low-density lipoprotein (LDL) apheresis comes forth as a treatment option. To the best of our knowledge, the following is the very first case of pediatric FH being treated by LDL-apheresis to be reported from India. A severely malnourished female child presented with yellowish skin lesions over different parts of the body, viz...

INTRODUCTION: Despite great recent progress, familial hypercholesterolemia (FH) is still underestimated, under-diagnosed and thus undertreated worldwide. We have very little information on exact prevalence of patients with FH in the Central, Eastern and Southern Europe (CESE) region. The aim of the study was to describe the epidemiological situation in the CESE region from data available. METHODS: All local leaders of the ScreenPro FH project were asked to provide local data on (a) expert guess of FH prevalence (b) the medical facilities focused on FH already in place (c) the diagnostic criteria used (d) the number of patients already evidenced in local database and (e) the availability of therapeutic options (especially plasma apheresis)...

BACKGROUND: Granulocyte and monocyte apheresis (GMA) has shown therapeutic efficacy in active ulcerative colitis (UC). We thought that in patients with pouchitis after proctocolectomy for UC, GMA might produce immunological effects in the intestinal mucosa, and improve clinical symptoms. This prospective study was to evaluate the efficacy of GMA for antibiotic-refractory pouchitis after proctocolectomy for UC. METHODS: A total of 13 patients with pouchitis disease activity index (PDAI) > 7 unresponsive to 2 weeks of antibiotic therapy were included...

Apheretic platelets are better quality blood components which reduce donor exposure and chances of TTIs to transfusion recipients when compared to the whole blood derived components. Though safe, these apheretic donations are associated with donor adverse events. We evaluated the incidence of such adverse events associated with the modern apheresis procedures that would provide an insight as well as help formulating preventive steps to avoid frequent occurrences of such events. This prospective audit-based observational study was conducted over 1 year...

Lipoprotein(a) (Lp(a)) is an independent cardiovascular risk factor playing a causal role for atherosclerotic cardiovascular disease (CVD). Lipoprotein apheresis (LA) is a safe well-tolerated outpatient treatment to lower LDL-C and Lp(a) by 60-70%, and is the ultimate escalating therapeutic option in patients with hyperlipoproteinemias (HLP) involving LDL particles. Major therapeutic effect of LA is preventing cardiovascular events. Lp(a)-HLP associated with progressive CVD has been approved as indication for regular LA in Germany since 2008...

The WAA apheresis registry was established in 2003 and an increasing number of centers have since then included their experience and data of their procedures. The registry now contains data of more than 74,000 apheresis procedures in more than 10,000 patients. This report shows that the indications for apheresis procedures are changing towards more oncological diagnoses and stem cell collections from patients and donors and less therapeutic apheresis procedures. In centers that continue to register, the total extent of apheresis procedures and patients treated have expanded during the latest years...

PURPOSE OF REVIEW: Preeclampsia remains one of the most important complications in pregnancy worldwide. With this review, we aim to give an overview on important research findings over the last years and their effects on current clinical management. RECENT FINDINGS: The association between preeclampsia and altered angiogenesis is nowadays widely accepted. Only during the last years, assessment of angiogenic factors such as the soluble fms-like tyrosine kinase-1-to-placental growth factor (sFlt-1/PlGF) ratio has become available to everyday clinical practice with commercially available automated measurements...

Myeloid-derived suppressor cells (MDSCs) play an important role in controlling inflammation. As such, they are both a therapeutic target and, based on the administration of ex-vivo-generated MDSCs, a therapeutic tool. However, there are relatively few reports describing methods to generate human MDSCs, and most of them rely on cells obtained from peripheral blood monocytes. We investigated alternative approaches to the generation of MDSCs from hematopoietic progenitors and monocytes. Purified CD34(+) hematopoietic progenitors from apheresis products and CD14(+) cells isolated from buffy coats were cultured in the presence of different combinations of cytokines...

Apheresis Medicine is a medical discipline that involves a variety of procedures (based on the targeted component to be removed or collected), indications (therapeutic vs. donation), and personnel (operators, management, and medical oversight). Apheresis services are accredited and/or regulated by a number of agencies and organizations. Given the complexity and the heterogeneity of apheresis services, it has been particularly challenging to formulate educational goals and define curriculums that easily cover all aspects of Apheresis Medicine...

Data collection on apheresis activities in Italy throughout 2015 including techniques, clinical indications and adverse effects was performed by means of a SidEM model questionnaire (aggregate data). These data provided by 67 Apheresis Units from 17 Italian regions, albeit rough, are sufficiently informative, mainly in comparison with previous surveys on these statistics. PEx has been the most frequent technique for plasma removal/treatment (11787 procedures) followed by LDL-apheresis (927 procedures). ECP/photopheresis has been the most frequent cytapheresis procedure: 6,606 session, mainlyby using the off-line technique...

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...
