Abstract
Intravenous immunoglobulin (IVIg) is used as treatment for several autoimmune and inflammatory conditions, but its specific mechanisms are not fully understood. Herein, we aimed to evaluate, using systems biology and artificial intelligence techniques, the differences in the pathophysiological pathways of autoimmune and inflammatory conditions that show diverse responses to IVIg treatment. We also intended to determine the targets of IVIg involved in the best treatment response of the evaluated diseases. Our selection and classification of diseases was based on a previously published systematic review, and we performed the disease characterization through manual curation of the literature. Furthermore, we undertook the mechanistic evaluation with artificial neural networks and pathway enrichment analyses. A set of 26 diseases was selected, classified, and compared. Our results indicated that diseases clearly benefiting from IVIg treatment were mainly characterized by deregulated processes in B cells and the complement system. Indeed, our results show that proteins related to B-cell and complement system pathways, which are targeted by IVIg, are involved in the clinical response. In addition, targets related to other immune processes may also play an important role in the IVIg response, supporting its wide range of actions through several mechanisms. Although B-cell responses and complement system have a key role in diseases benefiting from IVIg, protein targets involved in such processes are not necessarily the same in those diseases. Therefore, IVIg appeared to have a pleiotropic effect that may involve the collaborative participation of several proteins. This broad spectrum of targets and 'non-specificity' of IVIg could be key to its efficacy in very different diseases.

Abstract
In the last 25 years, intravenous immunoglobulin (IVIg) has had a major impact in the successful treatment of previously untreatable or poorly controlled autoimmune neurological disorders. Derived from thousands of healthy donors, IVIg contains IgG1 isotypes of idiotypic antibodies that have the potential to bind pathogenic autoantibodies or cross-react with various antigenic peptides, including proteins conserved among the "common cold"-pre-pandemic coronaviruses; as a result, after IVIg infusions, some of the patients' sera may transiently become positive for various neuronal antibodies, even for anti-SARS-CoV-2, necessitating caution in separating antibodies derived from the infused IVIg or acquired humoral immunity. IVIg exerts multiple effects on the immunoregulatory network by variably affecting autoantibodies, complement activation, FcRn saturation, FcγRIIb receptors, cytokines, and inflammatory mediators. Based on randomized controlled trials, IVIg is approved for the treatment of GBS, CIDP, MMN and dermatomyositis; has been effective in, myasthenia gravis exacerbations, and stiff-person syndrome; and exhibits convincing efficacy in autoimmune epilepsy, neuromyelitis, and autoimmune encephalitis. Recent evidence suggests that polymorphisms in the genes encoding FcRn and FcγRIIB may influence the catabolism of infused IgG or its anti-inflammatory effects, impacting on individualized dosing or efficacy. For chronic maintenance therapy, IVIg and subcutaneous IgG are effective in controlled studies only in CIDP and MMN preventing relapses and axonal loss up to 48 weeks; in practice, however, IVIg is continuously used for years in all the aforementioned neurological conditions, like is a "forever necessary therapy" for maintaining stability, generating challenges on when and how to stop it. Because about 35-40% of patients on chronic therapy do not exhibit objective neurological signs of worsening after stopping IVIg but express subjective symptoms of fatigue, pains, spasms, or a feeling of generalized weakness, a conditioning effect combined with fear that discontinuing chronic therapy may destabilize a multi-year stability status is likely. The dilemmas of continuing chronic therapy, the importance of adjusting dosing and scheduling or periodically stopping IVIg to objectively assess necessity, and concerns in accurately interpreting IVIg-dependency are discussed. Finally, the merit of subcutaneous IgG, the ineffectiveness of IVIg in IgG4-neurological autoimmunities, and genetic factors affecting IVIg dosing and efficacy are addressed.

Abstract
COVID-19 is an airway disease that has affected ~125 million people worldwide, caused by a novel coronavirus termed severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), spread through respiratory droplets, direct contact, and aerosol transmission. Although most patients presenting with absent or mild symptoms recover completely, the highest morbidity and mortality rates are seen in the elderly, and patients with comorbidities such as cardiovascular diseases, cancer, immunosuppressive diseases, diabetes, and pre-existing respiratory illnesses. Several therapeutic strategies have been examined, but a wide-ranging therapeutic option for particularly severe cases of COVID-19 remains to be elucidated. Considering the indications presented by COVID-19 patients who present similarly with inflammatory conditions, intravenous immunoglobulin (IVIG) administration has been examined as a possible route to reduce proinflammatory markers such as ESR, CRP and ferritin by reducing inflammation, based on its anti-inflammatory effects as indicated by utilisation of IVIG for numerous other inflammatory conditions. Herein, summarising the recent key clinical evaluations of IVIG administration, we present our hypothesis that administration of IVIG within a specific dosage would be extremely beneficial towards reducing mortality and perhaps even the length of hospitalisation of patients exhibiting severe COVID-19 symptoms.

Abstract
Over the last few decades, the advancement in reproductive technologies and protocols to improve embryo quality through culture techniques and genetic testing to eliminate chromosomally abnormal embryos resulted in better pregnancy rates and outcomes after fertility treatments. Unfortunately, some patients still struggle with recurrent implantation failures (RIFs) and recurrent pregnancy losses (RPLs). Immune etiologies have been attributed to play an important role in some of those patients. Maintaining a pre-conceptional anti-inflammatory environment for implantation and pregnancy continuation yields superior results. Intravenous immunoglobulin G (IVIG) treatment has been reported to enhance reproductive outcome in patients with RIF and RPL with immune dysregulations. In this systemic review, we analyzed outcomes of IVIG trials for RIF and RPL, its mechanism of action, dosing, administration, side-effects, and evidence for its use in women with RIF and RPL.

Abstract
Recurrent miscarriage (RM) is defined as two or more consecutive pregnancy losses that affect approximately 5% of conceived women worldwide. RM is a multi-factorial reproductive problem and has been associated with parental chromosomal abnormalities, embryonic chromosomal rearrangements, uterine anomalies, autoimmune disorders, endocrine dysfunction, thrombophilia, life style factors, and maternal infections. However, the exact cause is still undecided in remaining 50% of cases. Immunological rejection of the embryo due to exacerbated maternal immune reaction against paternal embryonic antigens has been set forth as one of the significant reason for RM. The accurate means that shield the embryo during normal pregnancy from the attack of maternal immune network and dismissal are inadequately implicit. However, it is suggested that the genetically irreconcilable embryo escapes maternal immune rejection due to communication among many vital cytokines exuded at maternal-embryonic interface both by maternal and embryonic cells. Previous investigations suggested the Th1/Th2 dominance in altered immunity of RM patients, according to which the allogenic embryo flees maternal T cell reaction by inclining the Th0 differentiation toward Th2 pathway resulting into diminished pro-inflammatory Th1 immunity. However, recently pro-inflammatory Th17 cells and immunoregulatory Treg cells have been discovered as essential immune players in RM besides Th1/Th2 components. Cytokines are believed to develop a complicated regulatory network so as to establish a state of homeostasis between the semi-allogenic embryo and the maternal immune system. However, an adverse imbalance among cytokines at maternal-embryonic interface perhaps due to their gene polymorphisms may render immunoregulatory means not enough to re-establish homeostasis and thus may collapse pregnancy.

Abstract
Intravenous immunoglobulin (IVIG) has been suggested for the treatment of many ailments due to its ability to modulate the immune system and to provide passive immunity to commonly circulating pathogens. Its use as primary and adjunctive therapy for the treatment of conditions affecting critically ill patients is an attractive option, especially when alternative therapy does not exist. The body of literature on the use of IVIG for the treatment of several serious conditions, including sepsis, toxic shock syndrome, acute myocarditis, Stevens-Johnson syndrome, toxic epidermal necrolysis, and H1N1 influenza, were reviewed. Despite advances in treatment of these conditions since they were first described, there remains a paucity of well-designed studies on the use of IVIG for their treatment. Therefore, the use of IVIG for treatment of these conditions remains controversial.

Abstract
Intravenous immunoglobulin (IVIG) preparations comprise pooled IgG antibodies from the serum of thousands of donors and were initially used as an IgG replacement therapy in immunocompromised patients. Since the discovery, more than 30 years ago, that IVIG therapy can ameliorate immune thrombocytopenia, the use of IVIG preparations has been extended to a wide range of autoimmune and inflammatory diseases. Despite the broad efficacy of IVIG therapy, its modes of action remain unclear. In this Review, we cover the recent insights into the molecular and cellular pathways that are involved in IVIG-mediated immunosuppression, with a particular focus on IVIG as a therapy for IgG-dependent autoimmune diseases.

Abstract
Intravenous immunoglobulin (IVIG) is a unique immune-modulating therapy that has a wide range of effects on the immune system at multiple levels. This allows it to be used successfully in a variety of immune-mediated, systemic, and neurological disorders, including the inflammatory myopathies. It is likely that the specific action of IVIG varies depending on the underlying pathogenesis of a given disease. In dermatomyositis (DM), IVIG has been shown to diminish the activity of complement and deposition of membrane attack complex on capillaries and muscle fibers, the expression of adhesion molecules, and cytokine production. IVIG also appears to modify gene expression in the muscle of DM patients. The mechanism by which IVIG affects muscle in polymyositis and inclusion body myositis has not been well-studied. However, it may work via suppression of T-cell activation (including cytotoxic T cells) and migration into muscle tissue and alterations in cytokine production. IVIG generally yields the greatest therapeutic benefit in DM and is often of marginal utility in inclusion body myositis. It is generally considered as second-line or adjunctive therapy in the inflammatory myopathies.

Abstract
Intravenous immunoglobulins (IVIg) have been shown in a number of trials, to be an effective treatment for the three main types of inflammatory neuropathies: Guillain-Barré Syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), and multifocal motor neuropathy (MMN). IVIg is thought to exert its immunomodulatory effects by affecting several components of the immune system including B-cells, T-cells, macrophages, complement, cytokines and cellular adhesion molecules. This article reviews the published evidence and the principal postulated mechanisms of action of intravenous immunoglobulins with special emphasis on inflammatory neuropathies.

Abstract
Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired heterogeneous disorder of immune origin affecting the peripheral nerves, causing motor weakness and sensory symptoms and signs. The precise pathophysiology of CIDP remains uncertain although B and T cell mechanisms are believed to be implicated. Intravenous immunoglobulins (IVIg) have been shown in a number of trials to be an effective treatment for CIDP. IVIg is thought to exert its immunomodulatory effects by affecting several components of the immune system including B-cells, T-cells, macrophages and complement. This article provides an overview of the pathogenesis of CIDP and of its treatment with IVIg.

Abstract
In this report, we show that affinity purified human anti-delta opioid receptor (DOR) autoantibodies from IVIG are specific to DOR and possess agonistic properties displayed by their ability to dramatically decrease forskolin stimulated cAMP accumulation. Anti-DOR autoantibody also caused phosphorylation of the opioid receptor. Anti-DOR autoantibody treatment showed a significant reduction in CXCR4 gene expression as well as surface protein expression. In contrast, anti-DOR autoantibody treatment significantly upregulated CCR5 gene and protein expression. The presence of anti-DOR autoantibodies in IVIG and their potent immunomodulatory activity is further evidence to support the cross-talk between the neuroendocrine and immune systems.

Abstract
Intravenous immunoglobulin (IVIg) contains a wide range of self-reactive immunoglobulins (Ig) G. Acidic pH is known to increase the reactivity of purified IgG with self-antigens. We describe here the target antigens of IgG autoantibodies in IVIg and analyze the influence of acidic pH on IgG reactivities. We used 2-DE and immunoblotting with protein extracts of human umbilical vein endothelial cells (HUVEC) and HEp-2 cells. Two IVIg preparations obtained by ethanol fractionation [one with an acidic pH step (acidic-IVIg) and one with beta-propiolactone (propiolactone-IVIg)] and a pool of sera from 12 healthy individuals were tested. Serum IgG of 3 healthy individuals and IgG purified from the same sera with elution at pH 2.8 were also tested individually. Finally, propiolactone-IVIg was acidified at pH 2.8. IgG obtained with a step at low pH recognized many more target spots than IgG obtained without acidic pH. Our findings demonstrate that an acidic pH step artificially enlarges the repertoire of self-reactive IgG. Thus, protein spots recognized by IgG in propiolactone-IVIg represent the core set of self-antigens targeted by IVIg. Overall, 96 proteins were identified by MS. Fourteen were recognized in both extracts including glycolysis proteins such as alpha-enolase, RNA processing and cytoskeletal proteins such as lamin-A/C.

Abstract
The remarkable success story of the therapeutic application of pooled immunoglobulin G (IgG) preparations from thousands of donors, the so-called intravenous IgG (IVIG) therapy, to patients with a variety of hematological and immunological disorders began more than half a century ago. Since then, the use of this primary blood product has increased constantly, resulting in the serious danger of shortages in supply. Despite its widespread use and therapeutic success, the mechanisms of action, especially of the anti-inflammatory activity, are only beginning to be understood. In this review, we summarize the clinical use of IVIG for different diseases and discuss recent data on the molecular mechanisms that might explain how this potent drug mediates its activity in vivo.

Abstract
Initially used for the treatment of immunodeficiencies, intravenous immunoglobulins (IVIg) have increasingly been used as immunomodulatory agents in autoimmune and inflammatory disorders. The mode of action of IVIg is enigmatic, probably involving Fc-dependent and/or F(ab')2-dependent nonexclusive mechanisms of action. IVIg broadly interacts with the different components of the immune system: cytokines, complement, Fc receptors, and several cell surface immunocompetent molecules. IVIg has also an impact on effector functions of immune cells. These mechanisms of action of IVIg reflect the importance of natural antibodies in the maintenance of immune homeostasis. We discuss here the recent advances in the understanding of immunoregulatory effects of IVIg, and we pointed out the need for new strategies to overcome the predicted increasing worldwide shortage of IVIg.

Abstract
Initially used for the treatment of immunodeficiencies, intravenous immunoglobulin (IVIg) has increasingly been used as an immunomodulatory agent in immune thrombocytopenic purpura, autoimmune neuropathies, systemic lupus erythematosus, myasthenia gravis, Guillain-Barré syndrome, and Kawasaki disease. Although IVIg benefits have been reported in many autoimmune and systemic inflammatory diseases, its mechanisms of immunomodulation are not fully understood and probably involve Fc-dependent and/or F(ab')(2)-dependent mutually non-exclusive effects. These mechanisms of action of IVIg reflect the importance of natural antibodies in the maintenance of immune homeostasis. We discuss here the recent advances in the understanding of immunoregulatory effects of IVIg.

Abstract
The original rationale for the therapeutic application of immunoglobulins was prevention and treatment of infectious diseases. With the description of agammaglobulinemia, substitution therapy became the primary indication for the use of immunoglobulins. Limitations and side effects of the intramuscular administration of immunoglobulins led to the development of preparations for intravenous use (IVIg). In the early 1980s an immunomodulatory effect of IVIg was described. Since then, the efficacy of IVIg has been established in controlled trials for diseases like idiopathic thrombocytopenic purpura, Kawasaki disease, Guillain-Barré syndrome, dermatomyositis, and many others. There is a large body of evidence that IVIg can modulate an immune reaction at the level of T cells, B cells, and macrophages, interferes with antibody production and degradation, modulates the complement cascade, and has effects on the cytokine network. However, the precise mechanism of action is not yet clear.

Abstract
Initially used as a replacement therapy for immunodeficiency diseases, intravenous immunoglobulin (IVIg) is now widely used for a number of autoimmune and inflammatory diseases. Considerable progress has been made in understanding the mechanisms by which IVIg exerts immunomodulatory effects in autoimmune and inflammatory disorders. The mechanisms of action of IVIg are complex, involving modulation of expression and function of Fc receptors, interference with activation of complement and the cytokine network and of idiotype network, regulation of cell growth, and effects on the activation, differentiation, and effector functions of dendritic cells, and T and B cells.

Abstract
Intravenous immunoglobulin (IGIV) has increasingly been used for the treatment of autoimmune and systemic inflammatory diseases in addition to supportive therapy of immunodeficient patients. IGIV is beneficial in several diseases, including acute and chronic/relapsing diseases, autoimmune diseases and inflammatory disorders. Therapeutic efficacy of IGIV has also been established in a number of dermatologic diseases. Although a considerable progress has been made in understanding the mechanisms by which IGIV exerts immunomodulatory functions in autoimmune diseases, they remain not fully elucidated. The mode of action of IGIV is complex, involving modulation of expression and function of Fc receptors, interference with activation of complement and the cytokine network, modulation of idiotype network, regulation of cell growth, alteration of cellular adhesion process, and effects on the activation differentiation and effector functions of T and B cells and of antigen-presenting cells. The therapeutic effects of IGIV most likely reflect the functions of natural antibodies in maintaining immune homeostasis in healthy people. The ability of IGIV to interact through V regions with complementary V regions of antibodies and antigen receptors as well as with relevant soluble and surface molecules provides the basis for inducing the selection of immune repertoires. Since IGIV is frequently used to treat autoimmune and inflammatory diseases for which evidence of its efficacy is insufficiently documented, controlled trials, particularly of some neurologic and dermatologic diseases, are imperative.

Abstract
Intravenous immunoglobulin (IVIG) preparations are derived from the pooled plasma of thousands of healthy donors and contain a complex mix of antibodies. Depending on the formulation, IVIG preparations contain variable amounts of monomeric and dimeric IgG. The biological and therapeutic significance of these IVIG fractions is still ill defined. Kinetic analysis of monomeric and dimeric IgG isolated by size-exclusion chromatography revealed a stable monomeric versus an unstable dimeric IgG fraction tending to dissociation. Biochemical analysis by 2D gel electrophoresis and isotype analysis showed no significant differences between the fractions. In contrast, comparative analysis by immunodot, ELISA, FACS, and immunohistology of monomeric and dimeric IgG fractions showed a preferential reactivity of the dimeric IgG on a variety of both self-antigens and exoantigens.

Abstract
Intravenous immunoglobulin (IVIg) has been used in the treatment of primary and secondary antibody deficiencies for over 25 years. It is a safe preparation with no long-term side effects. IVIg was first demonstrated to be effective in autoimmune disorders, two decades ago, in the treatment of acute immune thrombocytopenia. Since then, the therapeutic efficacy of IVIg has been established in Guillain Barré syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), myasthenia gravis (MG), dermatomyositis (DM), Kawasaki syndrome and the prevention of graft-versus-host disease in recipients of allogeneic bone marrow transplants and reported in a large number of other autoimmune and systemic inflammatory conditions.

Abstract
Natural immunoglobulin G (IgG) autoantibodies are present in the plasma of healthy individuals and, as a result, in pooled therapeutic intravenous immunoglobulin (IVIg) preparations. The production processes of commercial IVIg preparations involve different fractionation and virus-inactivation steps that include in some cases treatments at extreme conditions. Different physical and chemical treatments are known to augment greatly the reactivity of natural autoantibodies to self-antigens. It is not clear to what extent the self-reactivity of IVIg preparations is due to the presence of natural IgG antibodies in the plasma pools used for fractionation, and to what extent it is due to the treatments that the IgG molecules have been subjected to during the fractionation process. We compared the binding of seven different commercial IVIg preparations to human liver antigens. All studied IVIg's could be clearly separated into two distinct groups: those that possess significant self-reactivity and those with low binding to self-antigens. Increased self-binding was seen in the preparations produced using a fractionation step at low pH. The treatment of IVIg at low pH resulted in increasing the inhibitory effect of the pooled IgG on PHA-induced proliferation of human peripheral blood mononuclear cells. IVIg's with high and low self-binding may have different immunomodulating activities when infused to autoimmune patients.

Abstract
Intravenous Ig (IVIg) mediates protection from the effects of immune thrombocytopenic purpura (ITP) as well as numerous other autoimmune states; however, the active antibodies within IVIg are unknown. There is some evidence that antibodies specific for a cell-associated antigen on erythrocytes are responsible, at least in part, for the therapeutic effect of IVIg in ITP. Yet whether an IVIg directed to a soluble antigen can likewise be beneficial in ITP or other autoimmune diseases is also unknown. A murine model of ITP was used to determine the effectiveness of IgG specific to soluble antigens in treating immune thrombocytopenic purpura. Mice experimentally treated with soluble OVA + anti-OVA versus mice treated with OVA conjugated to rbcs (OVA-rbcs) + anti-OVA were compared. In both situations, mice were protected from ITP. Both these experimental therapeutic regimes acted in a complement-independent fashion and both also blocked reticuloendothelial function. In contrast to OVA-rbcs + anti-OVA, soluble OVA + anti-OVA (as well as IVIg) did not have any effect on thrombocytopenia in mice lacking the inhibitory receptor FcgammaRIIB (FcgammaRIIB(-/-) mice). Similarly, antibodies reactive with the endogenous soluble antigens albumin and transferrin also ameliorated ITP in an FcgammaRIIB-dependent manner. Finally, broadening the significance of these experiments was the finding that anti-albumin was protective in a K/BxN serum-induced arthritis model. We conclude that IgG antibodies directed to soluble antigens ameliorated 2 disparate IVIg-treatable autoimmune diseases.

Abstract
Intravenous immunoglobulin (i.v.Ig) has multiple actions on the immunoregulatory network that operate in concert with each other. For each autoimmune neuromuscular disease, however, there is a predominant mechanism of action that relates to the underlying immunopathogenetic cause of the respective disorder. The best understood actions of i.v.Ig include the following: (a) modulation of pathogenic autoantibodies, an effect relevant in myasthenia gravis (MG), Lambert-Eaton myasthenic syndrome (LEMS), Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), and stiff-person syndrome (SPS); (b) inhibition of complement activation and interception of membranolytic attack complex (MAC) formation, an action relevant to the complement-mediated mechanisms involved in GBS, CIDP, MG, and dermatomyositis (DM); (c) modulation of the inhibitory or activation Fc receptors on macrophages invading targeted tissues in nerve and muscle, as seen in CIDP, GBS, and inflammatory myopathies; (d) down-regulation of pathogenic cytokines and adhesion molecules; (e) suppression of T-cell functions; and (f) interference with antigen recognition. Controlled clinical trials have shown that i.v.Ig is effective as first-line therapy in patients with GBS, CIDP, and multifocal motor neuropathy (MMN), and as second-line therapy in DM, MG, LEMS, and SPS. In paraproteinemic IgM anti-MAG (myelin-associated glycoprotein) demyelinating polyneuropathies and inclusion body myositis (IBM), the benefit is variable, marginal, and not statistically significant. i.v.Ig has a remarkably good safety record for long-term administration, however, the following side effects have been observed: mild, infusion-rate-related reactions, such as headaches, myalgia, or fever; moderate but inconsequential events, such as aseptic meningitis and skin rash; and severe, but rare, complications, such as thromboembolic events and renal tubular necrosis. Future studies are needed to (a) find the appropriate dose and frequency of infusions that maintain a response; (b) address pharmacoeconomics, comparing the high cost of i.v.Ig to the cost of the other therapies, which, although less expensive, cause significantly more long-term side effects; (c) determine why some patients respond better than others; and (d) examine the merits of combining i.v.Ig with other immunosuppressive drugs.

Abstract
Intravenous immunoglobulins (IVIg) are therapeutic preparations of normal human IgG obtained from pools of more than 1000 healthy blood donors. They are currently used in the treatment of a wide range of auto-immune diseases, whether associated with auto-antibodies or auto-reactive T lymphocytes, as well as in the treatment of systemic inflammatory diseases. Several mechanisms of action have been identified during the last 20 years, including: (i) modulation of Fc receptors expression on leukocytes and endothelial cells; (ii) interaction with complement proteins; (iii) modulation of cytokines and chemokines synthesis and release; (iv) modulation of cell proliferation and apoptosis; (v) remyelinisation; (vi) neutralisation of circulating autoantibodies; (vii) selection of repertoires of B and T lymphocytes; (viii) interaction with other cell-surface molecules on lymphocytes and monocytes; (ix) corticosteroid sparing. These mechanisms of action are multiple and often intricate. However, they are still little known and further investigations are warranted.

Abstract
The unquestionable clinical success of left ventricular assist device (LVAD) implantation has, nevertheless, been accompanied by complications arising from interactions between the implanted biomaterial and the host immune system. The aberrant state of monocyte and T-cell activation resulting from these host/device interactions is accompanied by two parallel processes: (1) selective loss of Th1 cytokine producing CD4 T-cells through activation-induced cell death; and (2) unopposed activation of Th2 cytokine producing CD4 T-cells resulting in B-cell hyperreactivity and dysregulated immunoglobulin synthesis through Th2 cytokines and heightened CD40 ligand-CD40 interactions. The net results of these events is that, on the one hand, the LVAD recipient develops progressive defects in cellular immunity and is at increased risk of serious infection, and, on the other hand, is more likely to develop allosensitization, posing a significant risk to successful transplant outcome. Intravenous immunoglobulin therapy is an effective and safe modality for sensitized LVAD recipients awaiting cardiac transplantation, reducing serum anti-human lymphoicyte antigen (HLA) alloreactivity and shortening the duration to transplantation. The therapeutic and safety profile of intravenous immunoglobulin would appear to be superior to plasmapheresis. Immunosuppression incorporating intravenous cyclophosphamide before and after transplantation is safe and highly effective in sensitized LVAD recipients of cardiac transplantation. When used after transplantation as part of triple immunosuppressive regimens, cyclophosphamide is superior to mycophenolate mofetil in reducing episodes of allograft rejection in these patients. Because these immune dysfunctions appear to be related to the effects of excessive biomaterial-associated T-cell activation, future efforts will need to be directed at either altering the physical properties of the materials interacting with the host circulation or pharmacological intervention aimed more selectively at inhibiting T-cell activation.

Abstract
Intravenous immunoglobulins (IVIg) are therapeutic preparations of normal human immunoglobulin (Ig) G obtained from pools of blood from more than 1000 healthy donors, and exert immunomodulatory effects in autoantibody-mediated and T-cell-mediated autoimmune disorders and systemic inflammatory diseases. IVIg mechanisms of action in autoimmune diseases have been extensively analysed during the last 15 years and include the following: (i) interaction of the IgG Fc fragment with Fc receptors on leucocytes and endothelial cells; (ii) interaction of infused IgG with complement proteins; (iii) monocyte and lymphocyte modulation of synthesis and release of cytokines and cytokine antagonists; (iv) modulation of cell proliferation and reparation; (v) neutralisation of circulating autoantibodies; (vi) selection of immune repertoires; and (vii) interaction with other cell-surface molecules on T and B lymphocytes.

Abstract
The primordial combinatorial immune recognition repertoire arose in the evolution of jawed vertebrates approximately 450 million years ago as a rapid genetic process independent of antigenic selection. We propose that it encompassed the entire repertoire of innate immunity involving molecules that had evolved over billions of years. The 'antigen-driven' compartment involving invasive pathogens operates in 'real time' showing inducibility and increases in affinity. Individuals within a species differ in their repertoires because of distinct antigenic challenges, genetics, or local environmental effects. The 'homeostatic' compartment that recognizes invariant cell and serum components should be conserved in all individuals of a species. The potential to recapitulate the entire recognition spectrum must be regenerated during the formation of new species. Evidence for the capacity of the combinatorial response to encompass the entire preexisting repertoire was obtained in studies of natural human IgG antibodies present in intravenous immunoglobulin. Since essential cellular recognition and regulatory elements are conserved throughout evolution, we propose that the natural antibodies of sharks, the most anciently emerged vertebrates to possess the combinatorial immune response, will resemble those of mammals in showing specificity for the conserved recognition/regulatory molecules. If verified, this hypothesis will establish the fundamental importance of natural antibodies not only in defense, but in regulation and functional homeostasis of the individual.

Abstract
BACKGROUND Intravenous immune globulin (IVIG) therapy has been tried in the treatment of atopic dermatitis. Recently, the presence of serum-soluble CD5 (ssCD5) in atopic dermatitis was reported. OBJECTIVE IVIG effects on ssCD5 levels in atopic dermatitis were examined and the correlation of ssCD5 level changes with clinical and laboratory parameters were investigated. METHODS IVIG therapy was tried on 40 atopic dermatitis and 17 recurrent spontaneous abortion patients. Five atopic dermatitis patients received normal saline as a placebo control group. The clinical and laboratory parameters were evaluated on day 0, 1, 7 and 21 after administering the IVIG therapy. RESULTS With IVIG therapy, in atopic dermatitis, the ssCD5 level was 5.5 +/- 6.2 ng/mL before infusion (day 0), 15.2 +/- 12.1 ng/mL on day 1, 13.8 +/- 14.1 ng/mL on day 7, and 3.9 +/- 4.1 ng/mL on day 21. The clinical severity score was 350.5 +/- 120.3 on day 0, 420.4 +/- 174.8 on day 1, 250.0 +/- 121.2 on day 7, and 115.5 +/- 53.9 on day 21. White blood cell (WBC) counts and serum IgE levels showed a gradual decrease with IVIG infusions. Blood eosinophil fractions were 5.3 +/- 2.8% on day 0, 8.6 +/- 5.2% on day 1, 7.3 +/- 3.7% on day 7, and 6.8 +/- 4.0% on day 21. Changes in the total eosinophil count were insignificantly parallel with those of blood eosinophil fractions CONCLUSION In atopic dermatitis, IVIG therapy increased the ssCD5 levels. Further studies concerning the exact role of ssCD5 are needed.
