To harvest for T cell therapy, a 1.6-fold higher number of CD3(+) T cells was collected with MNC mode (N = 10) compared with Auto PBSC mode (N = 5) in COBE Spectra cell separator, but the blood product volume was increased by 3.5-fold. For therapeutic angiogenesis therapy, apheresis was initially performed using Auto PBSC mode (N = 4) to fine tune the blood product volume to omit cell concentration, but the collected number of mononuclear cells was lower than expected. However, an increase of the harvest cycle number from 3...

Macrophage activation syndrome (MAS) is a life-threating complication of systemic juvenile idiopathic arthritis (s-JIA). Steroid and cyclosporine (CsA) are effective for MAS, but, treatment for steroid- and CsA-resistant patients is still challenging. We report the case of steroid and CsA resistant s-JIA associated MAS misdiagnosed as Kawasaki disease (KD), who was successfully treated with the combination of plasma exchange (PE) and leukocytapheresis (LCAP) followed by plasma diafiltration (PDF). PE + LCAP effectively removed proinflammatory cytokines and reduced the number of peripheral white blood cells...

Amotosalen and ultraviolet A photochemical-based pathogen reduction using the InterceptTM Blood System is an effective and established technology for platelet and plasma components, which is adopted in more than 40 countries worldwide. Several reports point towards a reduced platelet function after Amotosalen/UVA exposure. The current study was undertaken to identify the mechanisms responsible for the early impairment of platelet function by the InterceptTM Blood System. Twenty-five platelet apheresis units were collected from healthy volunteers following standard procedures and split into 2 components, one untreated and the other treated with Amotosalen/UVA...

Human platelet lysates (PLs), which contain multiple neurotrophins, have been proposed for treating neurodegenerative disorders, including Parkinson's disease (PD). However, current PLs suspended in plasma have high protein content and contain fibrinogen/fibrin and, following activation, also proteolytic and thrombogenic enzymes. Upon brain administration, such PLs may saturate the cerebrospinal fluid and exert neurotoxicity. We assessed whether purified PLs, concentrated in neurotrophins, protected dopaminergic neurons in PD models...

Hypertriglyceridemia (HTG) is the third most common cause of acute pancreatitis (AP). The incidence of AP is around 10-20% with levels > 2,000 mg/dL. We present here a case of a 44-year-old male with history of uncontrolled diabetes mellitus and HTG admitted with severe abdominal pain. Labs revealed elevated lipase and amylase. CT of abdomen with contrast showed AP. He was found to have a triglyceride (TG) level of 6,672 mg/dL. Besides conventional treatment for AP with intravenous (IV) hydration, he was started on IV regular insulin along with dextrose saline...

Treatment of pelvic neoplasms with radiotherapy may develop sequelae, especially RHC. An 85-year-old male patient was admitted to a hospital emergency with gross hematuria leading to urinary retention and was diagnosed with RHC. The urinary bladder was probed, unobstructed, and maintained in continuous three-way saline irrigation. During 45 days of hospitalization, the patient underwent two cystoscopic procedures for urinary bladder flocculation, whole blood transfusions, and one platelet apheresis. None of these interventions led to clinical resolution...

Lipoprotein apheresis (LA) with dextran sulfate adsorption (DSA) is a reliable method to decrease LDL-cholesterol (C) concentrations in patients with homozygous familial hypercholesterolemia (HoFH). The objective of the present study was to investigate the impact of LA with DSA on the mRNA expression of genes associated with cardiovascular health in the whole blood of HoFH patients. Blood samples were collected before and after LA treatment with DSA in 9 HoFH patients. Microarray analyses were performed to measure the whole blood expression of >30 000 annotated genes pre- and post-LA...

BACKGROUND: Lenalidomide is an immunomodulatory drug that is also currently used in transplant-eligible patients with multiple myeloma. Previous studies have suggested a negative impact of lenalidomide on the mobilization of CD34(+) cells. No data are available regarding the more detailed composition of blood grafts after lenalidomide. STUDY DESIGN AND METHODS: In a multicenter, prospective study, we analyzed the mobilization of CD34(+) cells, graft cellular composition, and post-transplant hematologic recovery in 26 patients with multiple myeloma after lenalidomide-based induction and in 34 lenalidomide-naive controls with multiple myeloma...

In Japan, sacroiliitis is a very rare extraintestinal manifestation in patients with ulcerative colitis (UC), and it typically presents with intestinal symptoms. Radiography is used for diagnosis, and reveals erosions, sclerosis, and ankylosis, but magnetic resonance imaging is more useful for early detection. The treatment of spondyloarthropathy such as sacroiliitis and spondylitis includes physiotherapy, nonsteroidal anti-inflammatory drugs, sulfasalazine, and immunomodulators. In patients intolerant or cases refractory to these treatments, anti-tumor necrosis factor agents are recommended...

Hematopoietic stem cell (HSC) release is positively regulated by the sympathetic nervous system through the β3 adrenergic receptor. Preclinical studies have demonstrated that the combination of desipramine and G-CSF resulted in improved HSC mobilization. Here we present the results of an open-label single-arm pilot study in patients with multiple myeloma undergoing autologous stem cell transplantation (ASCT) to assess the safety and efficacy of desipramine combined with G-SCF to induce HSC mobilization. The primary endpoint was safety of the combination including engraftment kinetics...

Venous thrombus was recognized in the upper extremity of a 53-year-old man after blood donation. The patient presented with a 15-day history of swelling in the left upper-extremity that started 6 hours after apheresis. Contrast-enhanced computed tomography revealed clots in the deep veins of the left arm and the peripheral pulmonary artery. Blood donation had proceeded smoothly, and the patient had no thrombotic predisposition, except for a smoking habit. The thrombus resolved following anticoagulant therapy, and the patient' s clinical course was uncomplicated...

BACKGROUND: It has been shown that platelet transfusion carries a higher incidence of transfusion-related adverse events than any other blood components, and prolonged platelet storage is associated with more transfusion reactions, most of which are considered to be inflammatory responses. However, the role of complement, which has very important proinflammatory activities, in the pathogenesis of platelet-related adverse events has not been fully understood. STUDY DESIGN AND METHODS: Three units of platelets collected by apheresis were stored on a platelet rotator with the temperature controlled between 22 and 24°C...

Granulocyte and monocyte (GM) adsorptive apheresis (GMA) is an effective therapy for inflammatory disorders including inflammatory bowel disease (IBD). During GMA, the blood of a patient with IBD passes through a column to contact cellulose acetate (CA) beads at a temperature below body temperature, likely close to room temperature. Here we investigated the effect of temperature on GM adsorption to CA beads in vitro. We incubated peripheral blood with and without CA beads at 5°C, 25°C, 37°C, and 43°C and calculated the ratios of adsorbed GMs...

Hypocalcemic toxicity, because of return of citrate anion to the donor, is the major toxicity of apheresis platelet donation. Oral calcium carbonate, given prophylactically at the start of donation, has shown limited ability to alleviate this toxicity. We examined whether repeated prophylactic doses of calcium carbonate, or of a liquid preparation containing calcium citrate, calcium phosphate, and vitamin D3 , would be more effective at preventing symptoms of hypocalcemic toxicity. Symptoms were reported by 48% of donors who received no prophylaxis and 60% of donors who received 1000 mg of oral calcium carbonate at the start of, and every 20 minutes during, donation (P = 0...

The 7(th) edition of the American Society for Apheresis (ASFA) guidelines was composed by an international physicians committee, and includes 14 new diseases, and 2 new indications for diseases described in the former guidelines. Several indications have either changed names or were excluded from this edition. The guidelines are developed after taking into account documented evidence, either supporting or negating use of apheresis technology in the treatment of diseases. Based on this evidence, the committee revises, updates and includes or excludes disease entities/indications in the guidelines...
