Abstract
BACKGROUND The administration of high-dose intravenous immunoglobulin (IVIG) is a standard treatment for the management of Kawasaki disease (KD). IVIG is known to be a highly effective and safe treatment. CASE PRESENTATION We report the development of hemolytic anemia in seven children receiving repeated doses of IVIG. The children were aged 3-44 months and included 4 girls and 3 boys. All children received 10% IVIG and a second course of immunoglobulin because they did not respond to the first course of immunoglobulin. Two received high-dose aspirin (50 mg/kg), and five received low-dose aspirin (5 mg/kg). Two patients required additional methylprednisolone pulse therapy (30 mg/kg) after the second dose of immunoglobulin, and three patients received oral prednisolone therapy for defervescence. Three patients showed coronary artery dilation during hospitalization and normalized within two months. Pretreatment hemoglobin averaged 11.3-14.2 g/dL, and post-hemolytic anemia hemoglobin ranged from 7.4 to 9.6 g/dL, with a difference of 1.7-6.8 g/dL. Reticulocytes were increased to 3.3-13.2%. Peripheral blood smears showed normochromic normocytic anemia, and anisopoikilocytosis. All children were positive for warm-type antibodies with IgG+, C3d- in direct antiglobulin test, and the blood group was A + in five and B + in two. None of the patients received immunomodulatory therapy or red blood cell transfusions. They were followed for a year and all recovered. CONCLUSION Especially, in non-O blood group KD patients who are refractory to initial IVIG and require a second dose of IVIG or 10% formulation the possibility of immune hemolytic anemia should be carefully considered, and close follow-up should be maintained after therapy.

Intravenous immunoglobulin alteration in response to adverse reactions in neurological conditions: A retrospective cohort study. Transfus Med 2023; 33:478-482. [PMID: 37964154 DOI: 10.1111/tme.13013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 09/22/2023] [Accepted: 09/26/2023] [Indexed: 11/16/2023]
Abstract
INTRODUCTION Intravenous immunoglobulin (IVIg) is an important treatment in a range of neurological conditions. There is currently limited evidence regarding the frequency and management of IVIg-associated adverse reactions (AR) in neurological disorders. METHODS A single-centre 18-month retrospective cohort study was conducted for all patients at a single tertiary hospital receiving IVIg as an inpatient or the medical day unit. Electronic medical record AR and alerts were reviewed for entries relating to IVIg, and prescribing records associated with recent IVIg administration were reviewed for the use of premedications. Case note review was undertaken to identify AR associated with alterations in IVIg treatment (such as reduction in rate, use of premedications or cessation of IVIg). Demographic, patient, and treatment factors were analysed for associations with AR necessitating alteration in IVIg treatment. RESULTS This study included 98 individuals who received IVIg during the study period. Of these, 12 (12.1%) patients required an alteration in their IVIg treatment. In total, 3 (3.1%) of the 98 included patients required a reduced rate of IVIg, and 10 (10.2%) patients received premedication. The most common premedications were normal saline at the time of the infusion, cetirizine, and hydrocortisone. No demographic factors, indications or comorbidities were found to be associated with an increased likelihood of AR. However, an IVIg daily dose of >35 g and >45 g were associated with an increased likelihood of requiring IVIg treatment alteration due to AR. CONCLUSIONS Alterations to IVIg treatment due to AR are commonly required in neurology patients, and may be associated with higher daily doses of IVIg.

IVIg-induced headache: prospective study of a large cohort with neurological disorders. Neurol Sci 2023:10.1007/s10072-023-06731-x. [PMID: 36905450 DOI: 10.1007/s10072-023-06731-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Accepted: 02/24/2023] [Indexed: 03/12/2023]
Abstract
BACKGROUND Intravenous immune globulin (IVIg) is frequently used in some neurological diseases and is also the first-line therapy in Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, and multifocal motor neuropathy. We aimed to evaluate the frequency and characteristics of headaches, which is one of the most common side effects of IVIg treatment. METHODS Patients who received IVIg treatment for neurological diseases were prospectively enrolled in 23 centers. Firstly, the characteristics of patients with and without IVIg-induced headaches were analyzed statistically. Then, patients with IVIg-induced headaches were classified into three subgroups determined by their history: no primary headache, tension-type headache (TTH), and migraine. RESULTS A total of 464 patients (214 women) and 1548 IVIg infusions were enrolled between January and August 2022. The frequency of IVIg-related headaches was 27.37% (127/464). A binary logistic regression analysis performed with significant clinical features disclosed that female sex and fatigue as a side effect were statistically more common in the IVIg-induced headache group. IVIg-related headache duration was long and affected daily living activities more in patients with migraine compared to no primary headache and TTH groups (p = 0.01, respectively). CONCLUSION Headache is more likely to occur in female patients receiving IVIg and those who develop fatigue as a side effect during the infusion. Clinicians' awareness of IVIg-related headache characteristics, especially in patients with migraine, may increase treatment compliance.

Abstract
Background Although intravenous immunoglobulin (IVIG) therapy is generally safe and well tolerated, adverse reactions (ARs) do occur. The majority of these ARs are mild and transient. Risk factors for ARs associate with IVIG infusions are not well established. This study investigated possible risk factors influencing the occurrence of IVIG-associated ARs. Study Design and Methods This was a retrospective observational analysis of data accumulated over 5 years, including patient demographics, clinical condition, IVIG dosing regimens, number of IVIG infusions, and any ARs. Results ARs were associated with IVIG in 4.9% of patients and 2.5% of infusions. By univariate analyses, ARs correlated with female sex, adult age, high dose IVIG, and autoimmune disease. Multivariate logistic regression identified three statistically significant of risk factors: on a per-patient basis, being female (p=0.0018), having neuromuscular disease (p=0.0002), and receiving higher doses of IVIG per patient body weight (p<0.001), on a per-infusion basis, being female (p < 0.001), being adolescents to middle age (p < 0.001), and having neuromuscular disease (p < 0.001). Conclusion Neuromuscular disease emerged as one of the significant factors for ARs to IVIG.

Abstract
As of April 15, 2020, the ongoing coronavirus disease 2019 (COVID-2019) pandemic has swept through 213 countries and infected more than 1,870,000 individuals, posing an unprecedented threat to international health and the economy. There is currently no specific treatment available for patients with COVID-19 infection. The lessons learned from past management of respiratory viral infections have provided insights into treating COVID-19. Numerous potential therapies, including supportive intervention, immunomodulatory agents, antiviral therapy, and convalescent plasma transfusion, have been tentatively applied in clinical settings. A number of these therapies have provided substantially curative benefits in treating patients with COVID-19 infection. Furthermore, intensive research and clinical trials are underway to assess the efficacy of existing drugs and identify potential therapeutic targets to develop new drugs for treating COVID-19. Herein, we summarize the current potential therapeutic approaches for diseases related to COVID-19 infection and introduce their mechanisms of action, safety, and effectiveness.

Abstract
Introduction: Human cytomegalovirus (HCMV) is a major contributor of morbidity and mortality, and its management is essential for the successful outcome of solid organ and hematopoietic stem cell transplantation. Areas covered: This review discusses the safety profiles of currently available and emerging antiviral drugs and the other strategies for HCMV prevention and treatment after transplantation. Expert opinion: Strategies for management of HCMV rely largely on the use of antiviral agents that inhibit viral DNA polymerase (ganciclovir/valganciclovir, foscarnet, and cidofovir/brincidofovir) and viral terminase complex (letermovir), with different types and degrees of adverse effects. An investigational agent, maribavir, exerts its anti-CMV effect through UL97 inhibition, and its safety profile is under clinical evaluation. In choosing the antiviral medication to use, it is important to consider these safety profiles in addition to overall efficacy. In addition to antiviral drugs, reduction of immunosuppression is often generally needed in the management of HCMV infection, but with a potential risk of allograft rejection or graft-versus-host disease. The use of HCMV-specific or non-specific intravenous immunoglobulins remains debated, while adoptive HCMV-specific T cell therapy remains investigational, and associated with unique set of adverse effects.

Abstract
BACKGROUND Intravenous Immunoglobulin (IVIg) forms a cornerstone of effective treatment for acute and chronic inflammatory neuropathies, with a class I evidence base in Guillain-Barré Syndrome (GBS), Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) and multifocal motor neuropathy (MMN). It is generally considered to be a safe therapy however there are several recognised complications which are reviewed in this article. DISCUSSION AND CONCLUSION Most adverse events are immediate and mild such as headache, fever and nausea although more serious immediate reactions such as anaphylaxis may rarely occur. Delayed complications are rare but may be serious, including thromboembolic events and acute kidney injury, and these and associated risk factors are also discussed. We emphasise the importance of safe IVIg administration and highlight practical measures to minimise complications of this therapy.

Abstract
OBJECTIVES This analysis assessed the safety of intravenous immunoglobulin (IVIg) in the treatment of patients with neuroimmunological and immunological disorders in a home-based setting. METHODS Adverse reactions (ARs) were assessed in a retrospective review of 1176 patients receiving 28,677 home-based IVIg infusions between 1996 and 2013. RESULTS Of 1176 patients, 648 (55.1%) experienced IVIg-related ARs; 536 (45.6%) were mild, 78 (6.6%) moderate, and 34 (2.9%) severe. Thirty-seven (3.1%) patients were hospitalized because of ARs; of these, headache was most common (51.4%). Mean number of ARs per patient increased from 1.4 (low dose) to 3.6 (high dose). Incidence of ARs increased from 41% in the first 5-year moving average in 2003 to 65% in 2008. The number of ARs correlated with the number of infusions (ρ = 0.24; P < 0.001) and the average IVIg dose (ρ = 0.10; P < 0.001). CONCLUSIONS Low- and high-dose IVIg were safe and well tolerated with a few serious ARs in patients with neuroimmunological and immunological disorders.

Abstract
The efficacy of intravenous immunoglobulins (IVIg) in patients with autoimmune diseases (AID) has been known for several decades. Majority of these patients received IVIg in hospital. A retrospective study was conducted in 22 centers in France to evaluate the feasibility of the administration of Tegeline, an IVIg from LFB Biomedicaments, and assess its safety at home, compared to in hospital, in patients with AID. The included patients were at least 18 years old, suffering from AID, and treated with at least 1 cycle of Tegeline at home after receiving 3 consecutive cycles of hospital-based treatment with Tegeline at a dose between 1 and 2 g/kg/cycle. Forty-six patients with AID, in most cases immune-mediated neuropathies, received a total of 138 cycles of Tegeline in hospital and then 323 at home. Forty-five drug-related adverse events occurred in 17 patients who received their cycles at home compared to 24 adverse events in hospital in 15 patients. Serious adverse events occurred in 3 patients during home treatment, but they were not life-threatening and did not lead to discontinuation of Tegeline. Forty-five patients continued their treatment with Tegeline at home or in hospital; 39 (84.8%) were still receiving home treatment at the end of the study. In conclusion, the study demonstrates the good safety profile of Tegeline administered at home at high doses in patients with AID who are eligible for home administration of Tegeline.

Abstract
OBJECTIVE The aim of this review was to summarize key findings from the literature concerning the therapeutic role of intravenous immunoglobulins (IVIg) in idiopathic inflammatory myopathies (IIM), dissecting the evidence according to disease subtype and treatment indication, and to review the evidence relating to the mechanism of action of IVIg in IIM to ascertain rationale for continued research. METHODS Medline (Ovid) and Pubmed databases were searched from inception to July 2016 using relevant keywords. Original and review articles were retrieved for full-text review. Bibliographies of selected articles were also hand-searched for additional references. Data were summarized qualitatively and in tabular form. RESULTS The efficacy of IVIg in IIM is supported by 3 randomized controlled trials, involving dermatomyositis and polymyositis subjects, in refractory, relapsed, or steroid-dependent disease, as well as part of first-line therapy in elderly dermatomyositis subjects. Other indications for IVIg are supported by uncontrolled evidence only. Limitations of studies include open, uncontrolled or retrospective study designs, small and selected samples, short-term follow-up and ad hoc outcome measures. Despite the limited evidence, there is strong biological plausibility for the role of IVIg in IIM. CONCLUSION Robust, controlled evidence to support the use of IVIg using validated outcome measures is urgently required to guide therapeutic decision-making and maximize outcomes in IIM.

Quantitative Evidence of Wear-Off Effect at the End of the Intravenous IgG (IVIG) Dosing Cycle in Primary Immunodeficiency. J Clin Immunol 2016; 36:210-9.

Abstract
PURPOSE Intravenous IgG (IVIG) treatment wear-off is commonly experienced by patients, who report increased susceptibility to infection, and decreased quality of life towards the end of their 3- or 4-week dosing cycle, when serum IgG levels approach their trough. We quantified IVIG wear-off in terms of treatment efficacy and patient well-being. METHODS Data were collected from patients enrolled in three Phase III trials of Sandoglobulin NF Liquid or Privigen, treated every 3- or 4- weeks. Pooled analyses of raw patient data compared the rate of infection and other clinical outcomes during the course of the dosing cycle. Subjective symptoms of wear-off were quantified by comparing patient-reported overall well-being scores. RESULTS The probability of a first infection in the final week of the IVIG cycle was 1.26 (95% confidence intervals [CI]: 0.76-2.11; p = 0.3621) and 1.55 (95% CI: 1.04-2.32; p = 0.0314) times higher than in the first week, for patients on a 3-week cycle and 4-week dosing cycles, respectively. Wear-off, as manifested by a decrease in overall well-being, was experienced in 10% of all cycles and reported at least once by 61% of the patients on a 3-week cycle, and 43% of those on a 4-week cycle. CONCLUSIONS These findings confirm the existence of decreased efficacy (treatment wear-off) towards the end of a 3-4 week IVIG dosing cycle, and provide a quantifiable evaluation to a phenomenon typically reported anecdotally. For patients experiencing wear-off, increasing the IgG dose or shortening the dosing interval and/or a switch to SCIG may be beneficial.

BACKGROUND Guillain-Barré syndrome (GBS) is an acute, paralysing, inflammatory peripheral nerve disease. Intravenous immunoglobulin (IVIg) is beneficial in other autoimmune diseases. This is an update of a review first published in 2001 and previously updated in 2003, 2005, 2007, 2010 and 2012. Other Cochrane systematic reviews have shown that plasma exchange (PE) significantly hastens recovery in GBS compared with supportive treatment alone, and that corticosteroids alone are ineffective. OBJECTIVES We had the following four objectives.1. To examine the efficacy of intravenous immunoglobulin (IVIg) in hastening recovery and reducing the long-term morbidity from Guillain-Barré syndrome (GBS).2. To determine the most efficacious dose of IVIg in hastening recovery and reducing the long-term morbidity from GBS.3. To compare the efficacy of IVIg and plasma exchange (PE) or immunoabsorption in hastening recovery and reducing the long-term morbidity from GBS.4. To compare the efficacy of IVIg added to PE with PE alone in hastening recovery and reducing the long-term morbidity from GBS. SEARCH METHODS We searched the Cochrane Neuromuscular Disease Group Specialized Register (2 December 2013), CENTRAL (2013, Issue 12 in The Cochrane Library), MEDLINE (January 1966 to November 2013) and EMBASE (January 1980 to November 2013). We checked the bibliographies in reports of the randomised trials and contacted the authors and other experts in the field to identify additional published or unpublished data. SELECTION CRITERIA Randomised and quasi-randomised trials of IVIg compared with no treatment, placebo treatment, PE, or other immunomodulatory treatments in children and adults with GBS of all degrees of severity. We also included trials in which IVIg was added to another treatment. DATA COLLECTION AND ANALYSIS Two authors independently selected papers, extracted data and assessed quality. We collected data about adverse events from the included trials. MAIN RESULTS Twelve trials were found to be eligible for inclusion in this review. Seven trials with a variable risk of bias compared IVIg with PE in 623 severely affected participants. In five trials with 536 participants for whom the outcome was available, the mean difference (MD) of change in a seven-grade disability scale after four weeks was not significantly different between the two treatments: MD of 0.02 of a grade more improvement in the intravenous immunoglobulin than the plasma exchange group; 95% confidence interval (CI) 0.25 to -0.20. There were also no statistically significant differences in the other measures considered. Three studies including a total of 75 children suggested that IVIg significantly hastens recovery compared with supportive care. The primary outcome for this review, available for only one trial with 21 mildly affected children, showed significantly more improvement in disability grade after four weeks with IVIg than supportive treatment alone, MD 1.42, 95% CI 2.57 to 0.27.In one trial involving 249 participants comparing PE followed by IVIg with PE alone, the mean grade improvement was 0.2 (95% CI -0.14 to 0.54) more in the combined treatment group than in the PE alone group; not clinically significantly different, but not excluding the possibility of significant extra benefit. Another trial with 34 participants comparing immunoabsorption followed by IVIg with immunoabsorption alone did not reveal significant extra benefit from the combined treatment.Adverse events were not significantly more frequent with either treatment, but IVIg is significantly much more likely to be completed than PE.Small trials in children showed a trend towards more improvement with high-dose compared with low-dose IVIg, and no significant difference when the standard dose was given over two days rather than five days. AUTHORS' CONCLUSIONS A previous Cochrane review has shown that PE hastens recovery compared with supportive treatment alone. There are no adequate comparisons of IVIg with placebo in adults, but this review provides moderate quality evidence that, in severe disease, IVIg started within two weeks from onset hastens recovery as much as PE. Adverse events were not significantly more frequent with either treatment but IVIg is significantly much more likely to be completed than PE. Also, according to moderate quality evidence, giving IVIg after PE did not confer significant extra benefit. In children, according to low quality evidence, IVIg probably hastens recovery compared with supportive care alone. More research is needed in mild disease and in patients whose treatment starts more than two weeks after onset. Dose-ranging studies are also needed and one is in progress.

Abstract
Intravenous immunoglobulin (IVIg) is one of the first-line therapies for inflammatory neuropathies. Clinical use of IVIg for these disorders is limited by expense and availability. Here, we investigated a synthetic product alternative to IVIg. The aim of this study was to test the therapeutic efficacy of a novel recombinant polyvalent murine IgG2a Fc compound (stradomer™) in experimental autoimmune neuritis (EAN). Seventy-four Lewis rats were immunized with myelin, randomized into three groups, and were treated with albumin, IVIg, or stradomer at 1% of IVIg dose. Rats were assessed clinically, electrophysiologically, and histologically. The clinical disease severity was evaluated by clinical grading and weight changes. The electrophysiological studies recorded motor conduction velocity (MCV), amplitudes, and latencies of the evoked compound muscle action potential (CMAP) and spinal somatosensory evoked potential. The treatment efficacy of the IVIg and stradomer groups was compared to the albumin (control) group. We demonstrate that stradomer has a similar therapeutic efficacy to human IVIg in EAN. Rats receiving stradomer or IVIg showed significantly lower clinical scores and less prominent weight loss compared with controls. A statistically significant improvement in both MCV and the amplitudes of distal and proximal evoked CMAP was observed in the stradomer and IVIg groups. Finally, treatment with both IVIg and stradomer resulted in statistically less inflammation and demyelinating changes in the sciatic nerve as evidenced by lower histological grade. These results reveal the potential of using fully recombinant multimerized immunoglobulin Fc instead of IVIg for treating inflammatory neuropathies.

Recombinant IgG2a Fc (M045) multimers effectively suppress experimental autoimmune myasthenia gravis. J Autoimmun 2014; 52:64-73. [PMID: 24388113 DOI: 10.1016/j.jaut.2013.12.014] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2013] [Accepted: 12/15/2013] [Indexed: 11/20/2022]
Abstract
Myasthenia gravis (MG) is an autoimmune disorder caused by target-specific pathogenic antibodies directed toward postsynaptic neuromuscular junction (NMJ) proteins, most commonly the skeletal muscle nicotinic acetylcholine receptor (AChR). In MG, high-affinity anti-AChR Abs binding to the NMJ lead to loss of functional AChRs, culminating in neuromuscular transmission failure and myasthenic symptoms. Intravenous immune globulin (IVIg) has broad therapeutic application in the treatment of a range of autoimmune diseases, including MG, although its mechanism of action is not clear. Recently, the anti-inflammatory and anti-autoimmune activities of IVIg have been attributed to the IgG Fc domains. Soluble immune aggregates bearing intact Fc fragments have been shown to be effective treatment for a number of autoimmune disorders in mice, and fully recombinant multimeric Fc molecules have been shown to be effective in treating collagen-induced arthritis, murine immune thrombocytopenic purpura, and experimental inflammatory neuritis. In this study, a murine model of MG (EAMG) was used to study the effectiveness of this novel recombinant polyvalent IgG2a Fc (M045) in treating established myasthenia, with a direct comparison to treatment with IVIg. M045 treatment had profound effects on the clinical course of EAMG, accompanied by down-modulation of pathogenic antibody responses. These effects were associated with reduced B cell activation and T cell proliferative responses to AChR, an expansion in the population of FoxP3(+) regulatory T cells, and enhanced production of suppressive cytokines, such as IL-10. Treatment was at least as effective as IVIg in suppressing EAMG, even at doses 25-30 fold lower. Multimeric Fc molecules offer the advantages of being recombinant, homogenous, available in unlimited quantity, free of risk from infection and effective at significantly reduced protein loads, and may represent a viable therapeutic alternative to polyclonal IVIg.

Abstract
OBJECTIVES To assess the overall safety of high-dose intravenous immunoglobulin (IG) products used to treat patients with neuroimmunological disorders in a supervised home-based setting. METHODS The incidence of adverse reactions was assessed in a retrospective chart review of 420 patients who consecutively received 4076, home-based, individual, intravenous immunoglobulin (IVIG) infusions between January 2009 and December 2009. RESULTS A total of 90 patients (21.4%) developed adverse reactions related to IVIG administration (2.6% per individual infusion). A total of 95.5% of adverse reactions were mild, and no serious side effects were observed. The incidence of adverse reactions was significantly lower in the subgroup of patients with neuroimmunological disorders who received premedication (18.2% compared with 29.3%, P = 0.02). There was no significant statistical difference in the incidence of side effects among the different brands of IVIG used in this study. CONCLUSIONS The combination of premedication and well-defined clinical, IVIG infusion policies may reduce the incidence of high-dose IVIG adverse reactions administered in a home-based setting in patients with neuroimmunological disorders.

Abstract
This article reviews advances in the scientific basis and medical practice of plasmapheresis and cytapheresis therapies. Newly-characterized autoantibodies in neuromyelitis optica, Guillain-Barre variants, anti-neutrophil cytoplasmic antibody (ANCA) vasculitides, etc., exemplify the modern molecular biology which now provides a rigorous framework of understanding for the clinical practice of plasmapheresis. Clinical trials continue to clarify the appropriate use of therapeutic plasmapheresis (TPE) in these and other diseases. Centrifugal (cTPE) and membrane filtration (mTPE) types of plasmapheresis are compared, with details of the plasmapheresis prescription, anticoagulation choices, replacement fluids and other practical considerations. Plasma removal is more efficient with cTPE; mTPE systems have a lower plasma extraction ratio, and therefore require higher blood flow rates or longer procedure times. Autoantibodies and other pathogenic macromolecules targeted for removal by plasmapheresis can be depleted predictably when the plasma is discarded, as in conventional TPE. On-line plasma processing to regenerate the patient's own plasma avoids the need for replacement albumin solutions or plasma transfusion, but is inherently less efficient at removing the target molecule, so usually requires a longer procedure. Therapeutic white cell reduction (leukapheresis), platelet reduction (thrombocytapheresis) and red cell exchange (erythrocytapheresis) require centrifugal apheresis systems.

Abstract
Therapy with intravenous immunoglobulins (IVIg) is considered to be a safe treatment for a number of immune-mediated neurological diseases. Published data about prevalence of adverse effects range from 11 to 81%. The purpose of our study was to preserve a representative view on adverse effects by analysis of a large cohort of patients treated by IVIg. A recent prospective study reported 42.7% adverse events. The majority of patients presented with minor adverse effects, mostly asymptomatic laboratory changes. Rash or mild headache occurred especially when IVIg was administered with an infusion flow higher than 10 g/h. Severe complications like deep vein thrombosis or others are rare. In addition to its efficacy, IVIg therapy appears to be a safe therapy in immune-mediated neurological diseases. Most patients show no or minor adverse effects. Patients with pre-existent disorders like heart or renal insufficiency or immobilized patients, however, may be at higher risk for complications.

Abstract
Intravenous immunoglobulin (IVIg) infusions at 3-4 week intervals are currently standard therapy in the United States for patients with primary immune deficiency diseases (PIDD). To evaluate alternative modes of immunoglobulin administration we have designed an open-label study to investigate the efficacy and safety of a subcutaneously administered immunoglobulin preparation (16% IgG) in patients with PIDD. After their final IVIg infusion, 65 patients entered a 3-month, wash-in/wash-out phase, designed to bring patients to steady-state with subcutaneously administered immunoglobulin. This was followed by 12 months of weekly SCIg infusions, at a dose determined in a pharmacokinetic substudy to provide noninferior intravascular exposure. This resulted in a mean weekly dose of 158 mg/kg, calculated to equal 137% of the previous intravenous dose. Two patients (4%) each reported 1 serious bacterial infection (pneumonia), an annual rate of 0.04 per patient-year. There were 4.43 infections of any type per patient-year. Mean trough serum IgG levels increased from 786 to 1040 mg/dL during the study, a mean increase of 39%. The most frequent treatment-related adverse event was infusion-site reaction, reported by 91% of patients; this was predominantly mild or moderate, and the incidence decreased over time. No treatment-related serious adverse events were reported. We conclude that subcutaneous administration of 16% SCIg is a safe and effective alternative to IVIg for replacement therapy of PIDD.

Abstract
AIM To document the incidence of immediate and delayed adverse events (AE) following intravenous immunoglobulin (IVIG) infusion in children. METHODS Immediate and delayed adverse events were prospectively recorded for 345 infusions in 58 children receiving IVIG for immunodeficiency (n = 33) or immunomodulation (n = 25). For each infusion adverse events were documented during the infusion and by follow up interview 4-7 days later. RESULTS Immediate adverse events occurred in 10.3% and delayed adverse events in 41.4% of children treated during the study period. Three and a half per cent of the infusions were associated with immediate AE and 20.9% with delayed adverse events. Headache was the most common delayed AE, occurring in 24.1% of patients and 12.8% of infusions. CONCLUSIONS Delayed adverse events to IVIG infusions are common in children. They occur more frequently than immediate adverse events and are the cause of significant morbidity. Recognition of the high frequency of delayed adverse events is important in the care of children receiving IVIG therapy.

Abstract
Intravenous immunoglobulin (IVIg) is administered for various indications and generally considered a safe therapy. Most of the adverse effects (AEs) associated with IVIg administration are mild and transient. The immediate AEs include headache, flushing, malaise, chest tightness, fever, chills, myalgia, fatigue, dyspnea, back pain, nausea, vomiting, diarrhea, blood pressure changes, tachycardia, and anaphylactic reactions, especially in IgA-deficient patients. Late AEs are rare and include acute renal failure, thromboembolic events, aseptic meningitis, neutropenia, and autoimmune hemolytic anemia, skin reactions, and rare events of arthritis. Pseudohyponatremia following IVIg is important to be recognized. Renal failure, usually oliguric and transient, occurs mostly on using sucrose-containing products owing to osmotic injury. Among high-risk patients who have a previous renal disease, dehydration, diabetes mellitus, advanced age, hypertension, hyperviscosity, or are treated by other nephrotoxic medications, administration of a non-sucrose-containing IVIg product after accomplishing hydration, in a low concentration and a slow infusion rate while supervising urine output and kidney function, is recommended. Thromboembolic complications occur because of hyperviscosity especially in patients having risk factors including advanced age, previous thromboembolic diseases, being bedridden, diabetes mellitus, hypertension, dyslipidemia, or those receiving high-dose IVIg in a rapid infusion rate. Immediate AEs can be treated by the slowing or temporary discontinuation of the infusion and symptomatic therapy with analgesics, nonsteroidal anti-inflammatory drugs, antihistamines, and glucocorticoids in more severe reactions. Slow infusion rate of low concentration of IVIg products and hydration, especially in high-risk patients, may prevent renal failure, thromboembolic events, and aseptic meningitis.

Abstract
BACKGROUND Guillain-Barré syndrome is an acute, paralysing, inflammatory peripheral nerve disease. Intravenous immunoglobulin is beneficial in other autoimmune diseases. OBJECTIVES We aimed to determine the efficacy of intravenous immunoglobulin for treating Guillain-Barré syndrome. SEARCH STRATEGY We searched the Cochrane Neuromuscular Disease Group Trials Register (March 2005), MEDLINE (January 1966 to March 2005) and EMBASE (January 1980 to March 2005) using the terms 'Guillain-Barré syndrome' and 'acute polyradiculoneuritis'. SELECTION CRITERIA We included all randomised and quasi-randomised trials. DATA COLLECTION AND ANALYSIS Two authors independently selected papers, extracted data and assessed quality. MAIN RESULTS Another Cochrane systematic review has shown that plasma exchange significantly hastens recovery. We found six randomised trials comparing intravenous immunoglobulin with plasma exchange. We undertook a meta-analysis of five trials involving 536, mostly adult participants who were unable to walk unaided and had been ill for less than two weeks. Our primary outcome measure was the change in a seven-grade disability scale four weeks after randomisation. The weighted mean difference of this measure was not statistically significant, being only -0.02 (95% confidence interval -0.25 to 0.20) of a disability grade more improvement in the intravenous immunoglobulin than the plasma exchange group. There were no statistically significant differences in other measures. One trial involving 249 participants compared plasma exchange followed by intravenous immunoglobulin with plasma exchange alone. Another involving 37 participants compared immunoabsorption followed by intravenous immunoglobulin with immunoabsorption alone. Neither revealed significant extra benefit from intravenous immunoglobulin. One study with 39 participants showed a trend towards more improvement with high-dose compared with low-dose intravenous immunoglobulin. Another trial with 51 children found no significant difference in outcome when the standard dose was given over two days rather than five days. Three studies including a total of 75 participants suggested that in children intravenous immunoglobulin significantly hastens recovery compared with supportive care. AUTHORS' CONCLUSIONS In adults, there are no adequate comparisons with placebo. Randomised trials in severe disease show that intravenous immunoglobulin started within two weeks from onset hastens recovery as much as plasma exchange, which is known to be more effective than supportive care. Treatment with intravenous immunoglobulin is significantly more likely to be completed than plasma exchange. Giving intravenous immunoglobulin after plasma exchange did not confer significant extra benefit. In children, intravenous immunoglobulin probably hastens recovery compared with supportive care alone. More research is needed in mild disease and in treatment starting more than two weeks after onset of the condition. Dose-ranging studies are also needed.

Abstract
In addition to its U.S. Food and Drug Administration (FDA) approved conditions, immune globulin intravenous (IGIV) is now being used to treat a vast array of autoimmune disorders. Some of the reasons for this overall increase in the use of IGIV include its effectiveness and safety. Despite many years of safe use, side effects and adverse reactions still occur. Common and mild side effects associated with IGIV include: headache, malaise, nausea, low-grade fever, urticaria, arthralgias, and myalgia. These symptoms typically resolve within a few days after their onset. Although rare, the serious and potentially fatal side effects include: anaphylactic reactions, aseptic meningitis, acute renal failure, stroke, myocardial infarction, and other thrombotic complications. Many of these side effects have occurred in patients who have significant, underlying risk factors for the development of the event. Thus, it is vitally important that a thorough and comprehensive medical evaluation be performed on every patient who is being evaluated for potential IGIV therapy. This evaluation can, to some extent, significantly minimize the risk of these side effects. Careful, constant, and close monitoring by trained personnel during the infusion can also result in early detection of such events. Physicians should thoroughly discuss the risks and benefits of IGIV with patients who are being considered for this therapy.

Abstract
OBJECTIVE This study was performed to evaluate which factors influence the outcome of Guillain-Barré Syndrome (GBS), focusing on the choice of treatments. METHODS Sixty-three GBS patients were retrospectively studied and the following factors were evaluated: sex, age, days from onset of disease to the start of treatment, severity of symptoms, prior infection, autonomic dysfunction, bulbar palsy, anti-ganglioside antibody, and disease form, as well as the choice of treatment. Plasma adsorption (PA, n=39), plasma exchange (PE, n=14), or immunoglobulin treatment (IVIg, n=10) were performed in this study. Outcomes were evaluated using the functional grading scale (FGS) of Hughes. RESULTS The number of days needed for one functional grade improvement was significantly longer in the elderly, the severe symptom group, and patients with acute motor axonal form, and days needed for two functional grade improvement was significantly longer in the elderly, patients with autonomic dysfunction, and acute motor axonal form. The choice of treatments (PA, PE, or IVIg) did not significantly influence the outcome as determined by both univariate and multivariate analysis. CONCLUSION Although patient age, symptoms, and disease form influenced the outcome, treatment methods did not significantly influence the outcome. Since PA does not result in a risk of unknown infection, choosing a PA treatment may be justified, especially for patients (or doctors) who may be anxious about a possibility of unknown infection.

Abstract
As the use of intravenous immunoglobulin (IGIV) continues to expand, infusion nurses have a greater need for a comprehensive understanding of the product, patient risk factors, and comorbidities when developing guidelines for administering IGIV. Because immunoglobulin therapy is a blood derivative product, many nurses may not have as much experience administering this type of infusion. This article provides an in-depth overview of immunoglobulin therapy and helps to define the infusion nurse's major role in coordinating, assessing, and ensuring patient safety during IGIV administration.

Abstract
Multifocal motor neuropathy (MMN) is now a well-defined purely motor multineuropathy characterized by the presence of multifocal partial motor conduction blocks (CB), frequent association with anti-GM1 IgM antibodies, and usually a good response to high-dose intravenous immunoglobulin (IVIg) therapy. However, several issues remain to be clarified in the diagnosis, pathogenesis, and therapy of this condition including its nosological position and its relation to other chronic dysimmune neuropathies; the degree of CB necessary for the diagnosis of MMN; the existence of an axonal form of MMN; the pathophysiological basis of CB; the pathogenetic role of antiganglioside antibodies; the mechanism of action of IVIg treatments in MMN and the most effective regimen; and the treatment to be used in unresponsive patients. These issues are addressed in this review of the main clinical, electrophysiological, immunological, and therapeutic features of this neuropathy.

Abstract
We report the case of an 82-year-old woman with a diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP) for more than 10 years, who developed an ischemic stroke during infusion of immunoglobulin (IVIG). She had received IVIG intermittently for several years, and the previous 86 doses were well tolerated. Thromboembolism was suspected based on magnetic resonance angiogram and on further extension of the deficit after 4 days of evolution. Strokes were associated with the use of IVIG in different clinical circumstances. Pre-existing thrombogenic risk factors should be carefully considered for patients undergoing treatment with IVIG. Clinical evaluation, with attention to history, a focused vascular work-up, and looking for markers of dehydration, can identify the high-risk patient for whom a careful analysis of the risk/benefit ratio is warranted.

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
Although US immune globulin intravenous (human) (IGIV) products have been regarded as safe, it is important to recognize that many of the controlled clinical studies of IGIVs have been of modest size and have limited power to define the incidence of only the most common adverse events (AEs). A significant number of "postmarketing" serious AEs affecting renal, cardiovascular, CNS, integumentary, and hematologic organ systems have been reported. Variables potentially affecting the risk and intensity of adverse events associated with administration of IGIV include patient age, underlying condition, history of migraine, cardiovascular or renal disease, dose, concentration, rate of infusion, specific brand/formulation/excipients, and lot(s) of the particular IGIV product being administered. Each manufacturer's IGIV preparation is a unique product carrying its own specific evidence-based indications and safety profile. In view of the seriousness of potential adverse effects of IGIV products, and current lack of data surrounding their frequency, clinicians are advised to limit their prescription of these products for conditions for which efficacy is supported by adequate and well-controlled clinical trials. Prescribers should pay close attention to patient selection; consider the potential risk/benefit ratio vis-a-vis alternate therapies; and familiarize themselves with the identification, management, and proposed strategies to minimize the risks of IGIV.

Abstract
Myasthenia gravis (MG) is a syndrome of fluctuating skeletal muscle weakness that worsens with use and improves with rest. Eye, facial, oropharyngeal, axial, and limb muscles may be involved in varying combinations and degrees of severity. Its etiology is heterogeneous, divided initially between those rare congenital myasthenic syndromes, which are genetic, and the bulk of MG, which is acquired and autoimmune. The autoimmune conditions are divided in turn between those that possess measurable serum acetylcholine receptor (AChR) antibodies and a smaller group that does not. The latter group includes those MG patients who have serum antibodies to muscle-specific tyrosine kinase (MuSK). Therapeutic considerations differ for early-onset MG, late-onset MG, and MG associated with the presence of a thymoma. Most MG patients can be treated effectively, but there is still a need for more specific immunological approaches.

Abstract
BACKGROUND Guillain-Barré syndrome is an acute, paralysing, inflammatory peripheral nerve disease. Intravenous immunoglobulin purified from donated blood is beneficial in other autoimmune diseases. OBJECTIVES We aimed to determine the efficacy of intravenous immunoglobulin for treating Guillain-Barré syndrome. SEARCH STRATEGY We searched the Cochrane Neuromuscular Disease Group register (search updated 11 February 2003), MEDLINE and EMBASE (from January 2000 to February 2003) using Guillain-Barré syndrome and acute polyradiculoneuritis as the search terms. We also searched bibliographies of trials and made contact with their authors and other experts. SELECTION CRITERIA We included all randomised and quasi-randomised trials. DATA COLLECTION AND ANALYSIS Two reviewers examined the titles and abstracts of all the papers retrieved by the search, extracted the data and assessed the quality of the trials independently. MAIN RESULTS Two trials comparing intravenous immunoglobulin with supportive treatment were inadequate to establish its value. Another Cochrane systematic review has shown that plasma exchange hastens recovery. We found six randomised trials that compared intravenous immunoglobulin with plasma exchange. In a meta-analysis of five trials involving 536, mostly adult, participants who were unable to walk unaided and had been ill for less than two weeks. The primary outcome measure in this review was the change in a seven grade disability scale four weeks after randomisation. The weighted mean difference of this measure was not statistically significant, being only 0.04 (95% CI -0.26 to 0.19) of a disability grade more improvement in the intravenous immunoglobulin group than the plasma exchange group. There were also no statistically significant differences in time to walk unaided, mortality, and proportion of participants unable to walk without aid after a year. One trial involving 249 participants compared plasma exchange followed by intravenous immunoglobulin with plasma exchange alone, and another involving 37 participants compared immunoabsorption followed by intravenous immunoglobulin with immunoabsorption alone. Neither revealed significant extra benefit from intravenous immunoglobulin. One study of only 39 participants showed a trend towards more improvement with high-dose compared with low-dose intravenous immunoglobulin. REVIEWER'S CONCLUSIONS Although there are no adequate comparisons with placebo, intravenous immunoglobulin hastens recovery from Guillain-Barré syndrome as much as plasma exchange. Giving intravenous immunoglobulin after plasma exchange is not significantly better than plasma exchange alone. Randomised trials are needed to decide the effect of intravenous immunoglobulin in children, in adults with mild disease and in adults who start treatment after more than two weeks.

Abstract
The aim of this study was to provide an incremental cost-effectiveness analysis comparing intravenous immunoglobulin (IVIg) and prednisolone treatment for chronic inflammatory demyelinating polyradiculoneuropathy. Patients were recruited to a double-blind randomized crossover trial from nine European centres and received either prednisolone or IVIg during the first 6-week treatment period on which the economic evaluation was based. A societal perspective was adopted in measuring service use and costs, although the costs of lost employment were not included. The main outcome measure in the economic evaluation was the number of quality adjusted life years (QALYs) gained, with change in a 11-point disability scale used to measure clinical outcomes. Service use and quality of life data were available for 25 patients. Baseline costs were controlled for using a bootstrapped multiple regression model. The cost difference between the two treatments was estimated to be euro 3754 over the 6-week period. Health-related quality of life, as measured by the EuroQol EQ-5D instrument, increased more in the IVIg group but the difference was not statistically significant. Using a net-benefit approach it was shown that the probability of IVIg being cost-effective in comparison with prednisolone was 0.5 or above (i.e. was more likely to be cost-effective than cost-ineffective) only if one QALY was valued at over euro 250 000. The cost-effectiveness of IVIg is greatly affected by the price of IVIg and the amount administered. The impact of later side-effects of prednisolone on long-term costs and quality of life are likely to reduce the cost per QALY of IVIg treatment.

Abstract
High dose intravenous immunoglobulin (IVG) is increasingly used in a broad range of immune mediated diseases. Thrombosis was exceptionally reported as a complication of this therapy. We describe three cases of thrombotic complications during or soon after IVIG treatment: myocardial infarction in a man and cerebral infarctions in an elderly man, associated with peripheral ischemia in a woman. In addition we review the published cases in the literature and discuss the possible etiologic factors.

Abstract
Chronic inflammatory demyelinating polyneuropathy (CIDP) is a chronic, acquired immune and inflammatory disorder of the peripheral nervous system. The classic form of the disorder is manifested by progressive or relapsing proximal or generalized limb weakness and areflexia, and usually easily recognized; it is the large number of regional and functional variants and variety of associated illnesses that pose a challenge to the clinician in practice. Similarly, laboratory and electromyography criteria have been developed to confirm the diagnosis; however, these various schemes are contrived because only 50% to 60% of patients with typical clinical features of CIDP fulfill these strict electrodiagnostic research criteria. Several studies have established the efficacy of immune therapies such as corticosteroids, plasma exchange, and intravenous immune globulin as the mainstay of treatment of CIDP, but these treatments might provide only short-term benefit. This review offers an approach to the evaluation and management of patients with CIDP and highlights the difficult clinical problems in those who do not respond or frequently relapse after treatment with standard therapies such as patients with CIDP and concomitant axonal loss, and the assessment of those with CIDP and concurrent diseases such as diabetes mellitus.

Abstract
Treatment of neurological disorders with intravenous immunoglobulin (IVIg) is an increasing feature of our practice for an expanding range of indications. For some there is evidence of benefit from randomised controlled trials, whereas for others evidence is anecdotal. The relative rarity of some of the disorders means that good randomised control trials will be difficult to deliver. Meanwhile, the treatment is costly and pressure to "do something" in often distressing disorders considerable. This review follows a 1 day meeting of the authors in November 2000 and examines current evidence for the use of IVIg in neurological conditions and comments on mechanisms of action, delivery, safety and tolerability, and health economic issues. Evidence of efficacy has been classified into levels for healthcare interventions (tables 1 and 2).

Abstract
When the diagnosis of Rasmussen's encephalitis is being considered, it is important to rapidly exclude other causes of epilepsia partialis continua and hemiparesis. Although there is no good data from randomized trials of different immune-related therapies, treatment with immunoglobulin G (IgG), steroids, or plasmapheresis is advocated as first-line therapy. It is not unreasonable to institute at least two treatment options (eg, IgG followed by plasmapheresis) if response to the first treatment is poor. Functional hemispherectomy and its variants are associated with a lower long-term complication rate.

Abstract
This review summarizes the current status of intravenous immunoglobulin (IVIg) in the treatment of autoimmune neuromuscular disorders and the possible mechanisms of action of the drug based on work in vivo, in vitro, and in animal models. Supply of idiotypic antibodies, suppression of antibody production, or acceleration of catabolism of immunoglobulin G (IgG) are relevant in explaining the efficacy of IVIg in myasthenia gravis (MG), Lambert-Eaton myasthenic syndrome (LEMS), and antibody-mediated neuropathies. Suppression of pathogenic cytokines has putative relevance in inflammatory myopathies and demyelinating neuropathies. Inhibition of complement binding and prevention of membranolytic attack complex (MAC) formation are relevant in dermatomyositis (DM), Guillain-Barré syndrome (GBS), and MG. Modulation of Fc receptors or T-cell function is relevant in chronic inflammatory demyelinating polyneuropathy (CIDP), GBS, and inflammatory myopathies. The clinical efficacy of IVIg, based on controlled clinical trials conducted in patients with GBS, CIDP, multifocal motor neuropathy (MMN), DM, MG, LEMS, paraproteinemic IgM anti-myelin-associated glycoprotein (anti-MAG) demyelinating polyneuropathies, and inclusion body myositis is summarized and practical issues related to each disorder are addressed. The present role of IVIg therapy in other disorders based on small controlled or uncontrolled trials is also summarized. Finally, safety issues, risk factors, adverse reactions, spurious results or serological tests, and practical guidelines associated with the administration of IVIg in the treatment of neuromuscular disorders are presented.

Abstract
Patients with polymyositis or dermatomyositis should be treated with prednisone (approximately 1 mg/kg/d) for an initial period of 4 to 6 weeks. Once improvement occurs, the dose should be tapered and converted to an alternate-day regimen, which should be continued for at least 12 months. Methotrexate or azathioprine should be administered concomitantly to patients in whom there is inadequate control. The early introduction of one of these drugs allows more rapid reduction in the dose of prednisone and helps to avert serious side effects. Intravenous immunoglobulin therapy is indicated for patients who have immunodeficiency, who are unable to tolerate immu-nosuppressive drugs, whose conditions are deteriorating, or who have severe relapses. Cyclosporine or cyclophosphamide may be effective for resistant disease. Patients with inclusion body myositis should undergo a 3- to 6-month trial of prednisone, alone or in combination with methotrexate or azathioprine. Maintenance doses of these drugs should be continued if the patient's condition improves or stabilizes.

Abstract
A human intravenous immunoglobulin preparation (IVIg) released Ca2+ from the sarcoplasmic reticulum of cultured human skeletal muscle cells in a dose-dependent manner. Blocking the dihydropyridine-ryanodine receptor complex abrogated the IVIg-mediated Ca2+ response, whereas inhibition of the voltage-operated Na+-channels or acetylcholine receptors did not. This effect of IVIg was not mediated by its main component, the IgG molecules, and differed between preparations from different manufacturers. Heating destroyed the activity. Data shows that an unidentified serum protein present in IVIg can influence human muscle cells by an effect on the dihydropyridine receptor. This phenomenon may be important in interpreting the (side) effects of IVIg in neuromuscular diseases.
