Abstract
Transfusion-related acute lung injury (TRALI), defined as the onset of acute respiratory distress after blood transfusion, is a rare complication which is a leading cause of transfusion related-mortality. In this retrospective study, we report the French nationwide experience of intravenous immunoglobulin (IVIG)-related TRALI, with a literature review and analysis of management and outcome of this rare condition. With the pharmacovigilance services, we conducted a retrospective multicenter study in the French network of intensive care units with TRALI concomitant to IVIG use and pooled with data from a literature review. Overall, 17 cases have been included in this case-series, our case report, seven personal cases and nine cases from the literature review. The median age was 55 years [2-79] with 10/17 (59%) male subjects. The underlying diseases motivating IVIG infusion were neurologic diseases in 35% of cases (Guillain Barre syndrome = 2, peripheral neuropathy = 2, neurolupus = 1, myasthenia = 1), multiple myeloma with hypogammaglobulinemia (n = 2; 12%), primary hypogammaglobulinemia (n = 2; 12%), autoimmune cytopenias (n = 2; 12%), graft versus host cutaneous disease after allogeneic hematopoietic stem cell transplantation for acute myeloid leukaemia (n = 1), anti-HLA antibodies after lung transplant (n = 1), cancer-associated thrombotic thrombocytopenic purpura-haemolytic uremic syndrome (n = 1), Kawasaki disease (n = 1) and in experimental essay (n = 1). TRALI symptoms begin either after the start or during the infusion (n = 7; 41%), or after the infusion (n = 10; 59%, 10 min to 24 h). Besides respiratory distress, it was also noted shock (33%), fever (18 %), cough (18%), nausea/vomiting (18 %), chills (12%) and agitation (12%). The X-ray showed mainly bilateral alveolar opacities (n = 15; 88%). Mechanical ventilation was needed in nine cases (53%), with median 1-day duration [1-4]. Four patients (24%) died during hospitalisation in the intensive care unit. Given the increasing use of intravenous immunoglobulins, TRALI must now be discussed in cases of respiratory distress occurring during or immediately following the infusion even if this side effect remains rare.Key Points• TRALI must now be discussed in cases of respiratory distress occurring during or immediately following an infusion of intravenous immunoglobulins.

Targeting Transfusion-Related Acute Lung Injury: The Journey From Basic Science to Novel Therapies. Crit Care Med 2019; 46:e452-e458.

Abstract
OBJECTIVES Transfusion-related acute lung injury is characterized by the onset of respiratory distress and acute lung injury following blood transfusion, but its pathogenesis remains poorly understood. Generally, a two-hit model is presumed to underlie transfusion-related acute lung injury with the first hit being risk factors present in the transfused patient (such as inflammation), whereas the second hit is conveyed by factors in the transfused donor blood (such as antileukocyte antibodies). At least 80% of transfusion-related acute lung injury cases are related to the presence of donor antibodies such as antihuman leukocyte or antihuman neutrophil antibodies. The remaining cases may be related to nonantibody-mediated factors such as biolipids or components related to storage and ageing of the transfused blood cells. At present, transfusion-related acute lung injury is the leading cause of transfusion-related fatalities and no specific therapy is clinically available. In this article, we critically appraise and discuss recent preclinical (bench) insights related to transfusion-related acute lung injury pathogenesis and their therapeutic potential for future use at the patients' bedside in order to combat this devastating and possibly fatal complication of transfusion. DATA SOURCES We searched the PubMed database (until August 22, 2017). STUDY SELECTION Using terms: "Transfusion-related acute lung injury," "TRALI," "TRALI and therapy," "TRALI pathogenesis." DATA EXTRACTION English-written articles focusing on transfusion-related acute lung injury pathogenesis, with potential therapeutic implications, were extracted. DATA SYNTHESIS We have identified potential therapeutic approaches based on the literature. CONCLUSIONS We propose that the most promising therapeutic strategies to explore are interleukin-10 therapy, down-modulating C-reactive protein levels, targeting reactive oxygen species, or blocking the interleukin-8 receptors; all focused on the transfused recipient. In the long-run, it may perhaps also be advantageous to explore other strategies aimed at the transfused recipient or aimed toward the blood product, but these will require more validation and confirmation first.

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
Immunoglobulin has been widely used in a variety of diseases, including primary and secondary immunodeficiency diseases, neuromuscular diseases, and Kawasaki disease. Although a large number of clinical trials have demonstrated that immunoglobulin is effective and well tolerated, various adverse effects have been reported. The majority of these events, such as flushing, headache, malaise, fever, chills, fatigue and lethargy, are transient and mild. However, some rare side effects, including renal impairment, thrombosis, arrhythmia, aseptic meningitis, hemolytic anemia, and transfusion-related acute lung injury (TRALI), are serious. These adverse effects are associated with specific immunoglobulin preparations and individual differences. Performing an early assessment of risk factors, infusing at a slow rate, premedicating, and switching from intravenous immunoglobulin (IVIG) to subcutaneous immunoglobulin (SCIG) can minimize these adverse effects. Adverse effects are rarely disabling or fatal, treatment mainly involves supportive measures, and the majority of affected patients have a good prognosis.

Abstract
The anti-HLA-E IgG2a mAbs, TFL-006 and TFL-007, reacted with all HLA-I antigens, similar to the therapeutic preparations of IVIg. Indeed, IVIg lost its HLA reactivity, when its HLA-E reactivity was adsorbed out. US-FDA approved IVIg to reduce antibodies in autoimmune diseases. But the mechanism underlying IVIg-mediated antibody reduction could not be ascertained due to the presence of other polyclonal antibodies. In spite of it, the cost prohibitive high or low IVIg is administered to patients waiting for donor organ and for allograft recipients for lowering antiallograft antibodies. A mAb that could mimic IVIg in lowering Abs, with defined mechanism of action, would be highly beneficial for patients. Demonstrably, the anti-HLA-E mAbs mimicked several functions of IVIg relevant to suppressing the antiallograft Abs. The mAbs suppressed activated T cells and anti-HLA antibody production by activated B cells, which were dose-wise superior to IVIg. The anti-HLA-E mAb expanded CD4+, CD25+, and Foxp3+ Tregs, which are known to suppress T and B cells involved in antibody production. These defined functions of the anti-HLA-E IgG2a mAbs at a level superior to IVIg encourage developing their humanized version to lower antibodies in allograft recipients, to promote graft survival, and to control autoimmune diseases.

Abstract
The US Food and Drug Administration approved intravenous immunoglobulin (IVIg), extracted from the plasma of thousands of blood donors, for removing HLA antibodies (Abs) in highly sensitized patients awaiting organ transplants. Since the blood of healthy individuals has HLA Abs, we tested different IVIg preparations for reactivity to HLA single antigen Luminex beads. All preparations showed high levels of HLA-Ia and -Ib reactivity. Since normal nonalloimmunized males have natural antibodies to the heavy chains (HCs) of HLA antigens, the preparations were then tested against iBeads coated only with intact HLA antigens. All IVIg preparations varied in level of antibody reactivity to intact HLA antigens. We raised monoclonal Abs against HLA-E that mimicked IVIg's HLA-Ia and HLA-Ib reactivity but reacted only to HLA-I HCs. Inhibition experiments with synthetic peptides showed that HLA-E shares epitopes with HLA-Ia alleles. Importantly, depleting anti-HLA-E Abs from IVIg totally eliminated the HLA-Ia reactivity of IVIg. Since anti-HLA-E mAbs react with HLA-Ia, they might be useful in suppressing HLA antibody production, similar to the way anti-RhD Abs suppress production. At the same time, anti-HLA-E mAb, which reacts only to HLA-I HCs, is unlikely to produce transfusion-related acute lung injury, in contrast to antibodies reacting to intact-HLA.

Abstract
Three weeks after single-lung transplantation for pulmonary fibrosis, a patient with high serum levels of de novo donor-specific antibodies received high-dose intravenous immunoglobulin (IVIG) infusion (scheduled dose: 2 g/kg on 2 days) to prevent antibody-mediated rejection. Within the first hours after completion of infusions, he experienced acute lung injury involving the transplanted lung. Given the clinical evolution and the absence of an alternative diagnosis, transfusion-related acute lung injury (TRALI) was diagnosed. The IVIG administered on each day was from the same batch. At day 110, because of an increase in the serum titers of donor-specific antibodies, IVIG therapy was reintroduced but from a different batch, with excellent clinical tolerance. The lung injury was explored biologically, but no mechanism was revealed. Given the increasing use of IVIG in solid-organ recipients, clinicians should be aware of possible TRALI after IVIG infusion.

Abstract
Transfusion-related acute lung injury (TRALI) is a leading cause of transfusion-associated mortality that can occur with any type of transfusion and is thought to be primarily due to donor antibodies activating pulmonary neutrophils in recipients. Recently, a large prospective case controlled clinical study of cardiac surgery patients demonstrated that despite implementation of male donors, a high incidence of TRALI still occurred and suggested a need for additional interventions in susceptible patient populations. To examine if intravenous immunoglobulin (IVIg) may be effective, a murine model of antibody-mediated acute lung injury that approximates human TRALI was examined. When BALB/c mice were injected with the anti-major histocompatibility complex class I antibody 34-1-2s, mild shock (reduced rectal temperature) and respiratory distress (dyspnea) were observed and pre-treatment of the mice with 2 g/kg IVIg completely prevented these symptoms. To determine IVIg's usefulness to affect severe lung damage, SCID mice, previously shown to be hypersensitive to 34-1-2s were used. SCID mice treated with 34-1-2s underwent severe shock, lung damage (increased wet/dry ratios) and 40% mortality within 2 hours. Treatment with 2 g/kg IVIg 18 hours before 34-1-2s administration completely protected the mice from all adverse events. Treatment with IVIg after symptoms began also reduced lung damage and mortality. While the prophylactic IVIg administration did not affect 34-1-2s-induced pulmonary neutrophil accumulation, bone marrow-derived neutrophils from the IVIg-treated mice displayed no spontaneous ROS production nor could they be stimulated in vitro with fMLP or 34-1-2s. These results suggest that IVIg prevents murine antibody-mediated acute lung injury at the level of neutrophil ROS production and thus, alleviating tissue damage.
