Dynamic Changes in AQP4-IgG Level and Immunological Markers During Protein-A Immunoadsorption Therapy for NMOSD: A Case Report and Literature Review. Front Immunol 2021; 12:650782.

Abstract
The changes in the serum levels of aquaporin-4-IgG (AQP4-IgG), immunoglobulins, and inflammatory mediators in neuromyelitis optica spectrum disorder (NMOSD) cases treated with immunoadsorption have been rarely described in detail. Here we report a 29-year-old steroid-resistant NMOSD female with a severe disability (bilateral blindness and paraplegia) who received protein-A immunoadsorption as a rescue treatment. During the total 5 sessions, the circulating level of AQP4-IgG, immunoglobulins, and complement proteins (C3 and C4) showed a rapid and sawtooth-like decrease, and the serum AQP4-IgG titer declined from 1:320 to below the detectable limit at the end of the 3rd procedure. Of all the antibodies, IgG had the biggest removal rate (>96.1%), followed by IgM (>66.7%) and IgA (53%), while complement C3 and C4 also dropped by 73% and 65%, respectively. The reduced pro-inflammatory cytokines (interleukin-8 and tumor necrosis factor-α) and marked increased lymphocyte (T and B cell) counts were also observed. The improvement of symptoms initiated after the last session, with a low AQP4-IgG titer (1:32) persisting thereafter. Accordingly, protein-A immunoadsorption treatment could be one of the potential rescue therapies for steroid-resistant NMOSD patients with a severe disability.

Abstract
Critical care nephrology is an emerging sub-specialty with rapid technological advancement and a growing body of dedicated literature in blood purification techniques. Their applications have been extended to improve morbidity and survival in multiple organ dysfunctions. Novel techniques have also allowed us to push the frontiers in transplant medicine, giving high-immunological risk patients a chance at a kidney transplant where this was previously precluded by hyperacute antibody-mediated rejection. We aim to review the myriad extracorporeal blood purification techniques now available for treating various critical illnesses in our clinical practice. Some of these techniques will still require further clinical research to determine the optimal timing and dose in order to achieve significant improvement in clinical outcomes.

Abstract
The principle of a patient-specific immunoadsorber (PsIA) is demonstrated. Studies with model systems (HSA/anti-HSA) on immobilization, stability, and leakage form the basis for the presented fast-performance liquid chromatography (FPLC) and batch experiments, which were conducted using two different protein A adsorbers and autologous and heterologous PsIA systems. Experiments to determine the binding capacity of protein A adsorbers and PsIAs are described. In all experiments, the adsorption of plasma IgG, total protein, and C1q and C3d circulating immune complexes were measured. Plasma of patients with autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus) was investigated. Analysis was performed in both the initial plasma and the flow-through or supernatant. Results of the investigations using FPLC and batch experiments were compared. Autologous PsIA systems are suitable for the selective removal of elevated levels of circulating immune complexes in the plasma.

Abstract
Protein A (SPA), a major cell wall component of Staphylococcus aureus, has occupied numerous investigators from its discovery in the late fifties. Its availability and avid binding to human immunoglobulins have led to extensive usage for diagnostic and research purposes. Today, SPA-based extracorporeal immunoadsorption relies on two rather different systems, namely, SPA-silica (Prosorba), and SPA-Sepharose (Immunosorba). Both systems are approved by the Food and Drug Administration for the core indications of rheumatoid arthritis and idiopathic thrombocytopenic purpura (SPA-silica) or hemophilia with inhibitors (SPA-Sepharose). Off label indications include immune disorders with a conceivable connection between autoantibody titers and disease activity, like forms of glomerulonephritis, systemic lupus erythematodes, myasthenia, and the Guillain-Barré syndrome as well as alloantibody formation in the context of e.g., transplantation. This review summarizes historical developments and important properties of SPA. Indications for extracorporeal therapy are discussed on the basis of available information and personal experience.

Abstract
Therapy for acute myelogenous leukemia can be complicated by alloimmunization to histocompatibility antigens (HLA), with resultant refractoriness to platelet transfusions. Autologous peripheral blood or bone marrow stem cell transplantation (referred here collectively as 'autoBMT') is emerging as a standard consolidative strategy in acute myelogenous leukemia (AML). We had noted life-threatening bleeding associated with platelet transfusion refractoriness following autoBMT; we therefore retrospectively analyzed 39 AML patients for this complication following BMT. All patients received high-dose chemoradiotherapy, followed by infusion of allogeneic sibling donor (n = 12, alloBMT) or autologous (n = 27, autoBMT) stem cells. HLA alloimmunization was assessed if patients were suspected of immune refractoriness to random donor platelet transfusions. Within 100 days of stem cell infusion, one of three alloBMT and six of 12 autoBMT recipients tested were HLA alloimmunized (not statistically significant, NS). Five of six HLA alloimmunized autoBMT patients experienced delayed bleeding, which contributed to their demise while still in remission (P < 0.001). Increased platelet requirements in HLA alloimmunized autoBMT recipients were observed between days 61 and 100 post-BMT, at a median of 211 platelet transfusions vs 0 in non-alloimmunized autoBMT patients (P < 0.01) and 17 in alloBMT patients. Our data suggest that platelet transfusion refractoriness, when associated with HLA alloimmunization, is a risk factor for increased platelet transfusion requirements, delayed bleeding, and poor outcome following autoBMT for AML.

Abstract
Pre-existent humoral antibody to adenovirus potentially confounds human clinical trials involving intravascular administration of adenovirus. Using the LNCaP prostate cancer xenograft model in BALB/c nu/nu mice and the prostate-specific attenuated replication-competent adenovirus (ARCATM) CN706, we developed an animal model that systematically controls both the dose of intravascularly administered adenovirus and the titer of the pre-existent anti-Ad5 antibody, and then measures the virus-induced toxicity as well as antitumor activity. We prepared hyperimmune sera to adenovirus in rabbits, passively injected the purified rabbit anti-Ad5 antibody into tumor-bearing mice, and established measurable humoral anti-Ad5 antibody titers. CN706 was intravenously injected into the tail vein of animals 24 hr after passive anti-Ad5 antibody administration. In the absence of pre-existent antibody, the lethal dose (LD100) for BALB/c nu/nu mice was 2.5x10(11) CN706 particles, whereas 1x10(11) CN706 particles was not lethal. However, in the presence of a 1:80 pre-existent titer of Ad5 neutralizing antibody (NAb), intravenous injection of 5x10(11) CN706 particles was no longer lethal. In addition, pre-existent antibody also prevented antitumor activity in a dose-dependent manner: 1x 10(11) CN706 particles prevented LNCaP xenograft tumor progression, but antitumor activity was eliminated by a pre-existent 1:80 NAb titer. These results led us to propose transient removal of pre-existent adenovirus antibody by immunoapheresis. An affinity column of cloned virus capsid proteins was constructed that was able to specifically remove adenovirus antibody from human clinical serum samples. A 5-min disposable immunoassay was also developed to monitor the level of pre-existent antibody in sera before and after immunoapheresis. Clinically, this approach may enable controlled clinical studies of intravenously administered adenovirus in patients with pre-existent anti-adenovirus antibody.

Abstract
Pediatric therapeutic apheresis is reviewed including what it is, how it is performed and indications for its use. Pediatric patients are special, and the unique needs for replacement fluids and attention to access, anticoagulation, volume shifts and hypothermia are stressed. While all indications cannot be addressed, the procedures most commonly performed are reviewed. These include erythrocytapheresis, leukaphereses and plasma exchanges. A table details the strength of evidence supporting the use of apheresis procedures for many of these indications.

Abstract
Plasmapheresis (PP), staphylococcal protein A immunoadsorption (SPI), and extracorporeal photochemotherapy (EP) have been utilized in cancer treatment for about 20 years. PP removes immune complexes and induces a temporary increase in T4/T8 ratio, natural killer cell activity, and blastogenic responses. SPI removes immune complexes, enhances lymphocytic responses, and activates complement. EP increases lysis of circulating lymphoma cells by CD8+ cytotoxic T cells and increases tumor necrosis factor production by host monocytes. PP induces partial remission in about 28% of patients, but this remission is short lived. SPI gives similar results. Addition of PP to chemotherapy has been reported to prolong survival in patients with multiple myeloma. EP appears useful in treating cutaneous T cell lymphomas with 25% of patients achieving complete response and 50% of patients attaining partial remission. Thus, PP and SPI induce short-lived immune responses, but have no proven clinical utility. EP may be useful in the treatment of cutaneous T cell lymphomas.
