Prevention of Infections During Primary Immunodeficiency

Prevention of Infections During Primary Immunodeficiency | Immunopathology & Immunotherapy | Scoop.it
Alfredo Corell's insight:

Because infectious diseases are a major source of morbidity and mortality in the majority of patients with primary immunodeficiencies (PIDs), the application of a prophylactic regimen is often necessary. However, because of the variety of PIDs and pathogens involved, and because evidence is scarce, practices are heterogeneous. To homogenize practices among centers, the French National Reference Center for PIDs aimed at elaborating recommendations for anti-infectious prophylaxis for the most common PIDs. We performed a literature review of infectious complications and prophylactic regimens associated with the most frequent PIDs. Then, a working group including different specialists systematically debated about chemoprophylaxis, immunotherapy, immunization, and recommendations for patients. Grading of prophylaxis was done using strength of recommendations (decreasing from A to D) and evidence level (decreasing from I to III). These might help infectious diseases specialists in the management of PIDs and improving the outcome of patients with PIDs.

Chimeric Antigen Receptor (CAR) T-Cell Immunotherapy for Leukemia and beyond

Published Online: Friday, August 29, 2014
Alfredo Corell's insight:
Abstract

Chimeric antigen receptor (CAR) T-cell therapy is an immunotherapy in which the patient’s own T cells are isolated in the laboratory, redirected with a synthetic receptor to recognize a particular antigen or protein, and reinfused into the patient. Clinical trials of CAR T cells directed to the CD19 antigen have shown impressive results in advanced B-cell malignancies at multiple academic centers over the last 3 years. We describe the technology of CAR T cells, findings at 5 academic centers, and toxicities associated with CAR T cell-treatment and their management. Although CAR T cells for B-cell malignancies are the most advanced in terms of clinical testing, CAR T cells are the basis of a new platform technology that is poised to be expanded to other hematologic and nonhematologic malignancies, especially as new targets are identified and manufacturing processes are streamlined.

Are complement deficiencies really rare? Overview on prevalence,
clinical importance and modern diagnostic approach

Are complement deficiencies really rare? Overview on prevalence,<br/>clinical importance and modern diagnostic approach | Immunopathology & Immunotherapy | Scoop.it
http://www.bragid.org.br/_download/artigos/are_complement_def_rare.pdf
Alfredo Corell's insight:

Complement deficiencies comprise between 1 and 10% of all primary immunodeficiencies (PIDs) accord-ing to national and supranational registries. They are still considered rare and even of less clinicalimportance. This not only reflects (as in all PIDs) a great lack of awareness among clinicians and gen-eral practitioners but is also due to the fact that only few centers worldwide provide a comprehensivelaboratory complement analysis. To enable early identification, our aim is to present warning signs forcomplement deficiencies and recommendations for diagnostic approach. The genetic deficiency of anyearly component of the classical pathway (C1q, C1r/s, C2, C4) is often associated with autoimmune dis-eases whereas individuals, deficient of properdin or of the terminal pathway components (C5 to C9), arehighly susceptible to meningococcal disease. Deficiency of C1 Inhibitor (hereditary angioedema, HAE)results in episodic angioedema, which in a considerable number of patients with identical symptomsalso occurs in factor XII mutations. New clinical entities are now reported indicating disease associa-tion with partial complement defects or even certain polymorphisms (factor H, MBL, MASPs). Mutationsaffecting the regulators factor H, factor I, or CD46 and of C3 and factor B leading to severe dysregulationof the alternative pathway have been associated with renal disorders, such as atypical hemolytic uremicsyndrome (aHUS) and – less frequent – with membranoproliferative glomerulonephritis (MPGN). Wesuggest a multi-stage diagnostic protocol starting based on the recognition of so called warning signswhich should aid pediatricians and adult physicians in a timely identification followed by a step-wisecomplement analysis to characterize the defect at functional, protein and molecular level.© 2014 Published by Elsevier

A major effort to understand a not so rare immunodeficiency
Alfredo Corell's insight:

Common variable immunodeficiency (CVID) is the most frequent of the large group of primary (inborn) immunodeficiencies. As the name indicates, the disease is highly variable. While the underlying defect is a lack of antibodies in the blood, patients develop a wide range of symptoms, from respiratory infections to autoimmune disorders and neoplasms, and treating such patients poses many challenges. Notably, the replacement of antibodies (known as immunoglobulin (Ig) replacement) alone does not seem to solve all symptoms; studies in the past have tried to group patients into different phenotypes, also to help identify suitable treatment, but our understanding of the disease remains limited.

Those in self-nonself camp, the more dominant of the two camps, would see a threat in the molecular mimics and link those to autoimmunity. Whereas the danger or damage theory proponents would argue that the presence or absence of molecular mimicry by itself means nothing unless the mimicked code evokes damage. Data can be found supporting either argument.

Identification of a mast-cell-specific receptor crucial for pseudo-allergic drug reactions : Nature : Nature Publishing Group

Identification of a mast-cell-specific receptor crucial for pseudo-allergic drug reactions : Nature : Nature Publishing Group | Immunopathology & Immunotherapy | Scoop.it
Mast cells are primary effectors in allergic reactions, and may have important roles in disease by secreting histamine and various inflammatory and immunomodulatory substances. Although they are classically activated by immunoglobulin (Ig)E antibodies, a unique property of mast cells is their antibody-independent responsiveness to a range of cationic substances, collectively called basic secretagogues, including inflammatory peptides and drugs associated with allergic-type reactions. The pathogenic roles of these substances have prompted a decades-long search for their receptor(s). Here we report that basic secretagogues activate mouse mast cells in vitro and in vivo through a single receptor, Mrgprb2, the orthologue of the human G-protein-coupled receptor MRGPRX2. Secretagogue-induced histamine release, inflammation and airway contraction are abolished in Mrgprb2-null mutant mice. Furthermore, we show that most classes of US Food and Drug Administration (FDA)-approved peptidergic drugs associated with allergic-type injection-site reactions also activate Mrgprb2 and MRGPRX2, and that injection-site inflammation is absent in mutant mice. Finally, we determine that Mrgprb2 and MRGPRX2 are targets of many small-molecule drugs associated with systemic pseudo-allergic, or anaphylactoid, reactions; we show that drug-induced symptoms of anaphylactoid responses are significantly reduced in knockout mice; and we identify a common chemical motif in several of these molecules that may help predict side effects of other compounds. These discoveries introduce a mouse model to study mast cell activation by basic secretagogues and identify MRGPRX2 as a potential therapeutic target to reduce a subset of drug-induced adverse effects.

Autoimmune Encephalitis—Antibody Targets and Their Potential Pathogenicity in Immunotherapy-responsive Syndromes

Autoimmune Encephalitis—Antibody Targets and Their Potential Pathogenicity in Immunotherapy-responsive Syndromes | Immunopathology & Immunotherapy | Scoop.it
European Neurological Review, 2014;9(1):87–92


Alfredo Corell's insight:
Abstract:

Autoimmune encephalitis (AIE) associated with neural autoantibodies is increasingly recognized as a cause of subacute onset amnesia, confusion, and seizures. In the past decade, several key antibody targets have been identified in AIE. These include the N-methyl D-aspartate (NMDA) receptors, voltage-gated potassium channel complexes—in particular leucine-rich glioma inactivated 1 (LGI1) and glutamic acid decarboxylase (GAD). There is accumulating clinical and laboratory evidence that antibodies targeting the extracellular domains of cell-surface molecules are directly pathogenic. Each antibody target associates with a spectrum of clinical features and relative response to immunotherapies. These immunotherapies have been shown to improve short- and long-term clinical outcomes in affected patients. AIE is an important differential diagnosis to consider in patients presenting with symptoms of encephalitis as early diagnosis can lead to successful treatment.

Alopecia areata (AA) is a common autoimmune disease resulting from damage of the hair follicle by T cells.
Alfredo Corell's insight:
Nature Medicine (2014) doi:10.1038/nm.3645
Alopecia areata (AA) is a common autoimmune disease resulting from damage of the hair follicle by T cells. The immune pathways required for autoreactive T cell activation in AA are not defined limiting clinical development of rational targeted therapies1. Genome-wide association studies (GWAS)2 implicated ligands for the NKG2D receptor (product of the KLRK1 gene) in disease pathogenesis. Here, we show that cytotoxic CD8+NKG2D+ T cells are both necessary and sufficient for the induction of AA in mouse models of disease. Global transcriptional profiling of mouse and human AA skin revealed gene expression signatures indicative of cytotoxic T cell infiltration, an interferon-γ (IFN-γ) response and upregulation of several γ-chain (γc) cytokines known to promote the activation and survival of IFN-γ–producing CD8+NKG2D+ effector T cells. Therapeutically, antibody-mediated blockade of IFN-γ, interleukin-2 (IL-2) or interleukin-15 receptor β (IL-15Rβ) prevented disease development, reducing the accumulation of CD8+NKG2D+ T cells in the skin and the dermal IFN response in a mouse model of AA. Systemically administered pharmacological inhibitors of Janus kinase (JAK) family protein tyrosine kinases, downstream effectors of the IFN-γ and γc cytokine receptors, eliminated the IFN signature and prevented the development of AA, while topical administration promoted hair regrowth and reversed established disease. Notably, three patients treated with oral ruxolitinib, an inhibitor of JAK1 and JAK2, achieved near-complete hair regrowth within 5 months of treatment, suggesting the potential clinical utility of JAK inhibition in human AA.

Personalized medicine against hereditary immunodeficiency

Personalized medicine against hereditary immunodeficiency | Immunopathology & Immunotherapy | Scoop.it
Researchers have found a method to repair the gene mutation causing agammaglobulinemia, an immunodeficiency disease that almost exclusively affects boys and in which the body lacks the ability to produce immunoglobulins (gamma globulin). The disease is characterized by recurring bacterial infections, mainly in the respiratory system, and persons who suffer from the illness currently need life-long gamma globulin treatment.
Alfredo Corell's insight:

X-linked agammaglobulinemia (XLA) is an inherited immunodeficiency that results from mutations within the gene encoding Bruton’s tyrosine kinase (BTK). Many XLA-associated mutations affect splicing of BTK pre-mRNA and severely impair B cell development. Here, we assessed the potential of antisense, splice-correcting oligonucleotides (SCOs) targeting mutated BTK transcripts for treating XLA. Both the SCO structural design and chemical properties were optimized using 2′-O-methyl, locked nucleic acid, or phosphorodiamidate morpholino backbones. In order to have access to an animal model of XLA, we engineered a transgenic mouse that harbors a BAC with an authentic, mutated, splice-defective human BTK gene. BTK transgenic mice were bred onto a Btk knockout background to avoid interference of the orthologous mouse protein. Using this model, we determined that BTK-specific SCOs are able to correct aberrantly spliced BTK in B lymphocytes, including pro–B cells. Correction of BTK mRNA restored expression of functional protein, as shown both by enhanced lymphocyte survival and reestablished BTK activation upon B cell receptor stimulation. Furthermore, SCO treatment corrected splicing and restored BTK expression in primary cells from patients with XLA. Together, our data demonstrate that SCOs can restore BTK function and that BTK-targeting SCOs have potential as personalized medicine in patients with XLA.

Highlights

The presence of antibodies against EBV-early-antigen, is associated with SS.

Anti-Ro/SSA and anti La/SSB correlate the presence of anti-EBVEA antibodies.

Specific cytokines and TAP alleles correlate with different clinical manifestations in SS.

Alfredo Corell's insight:
Abstract

Sjögren's syndrome (SS) is an autoimmune disease characterized primarily by lymphocytic infiltration of the exocrine glands, and autoantibody production. Multiple environmental factors affecting an individual with a genetic susceptibility may trigger the development of SS. Herein, we aimed to evaluate links between the different pebbles in the mosaic of SS. Demographic, clinical data and blood samples were gathered from 82 consecutive patients with SS, and 139 healthy controls. Samples were analyzed for infectious serology and auto-antibodies as well as for relevant genetic mutations (TAP genes) and cytokines levels. An immune response (IgG) against Epstein–Barr virus (EBV) early antigen (EA) was positively associated with SS (OR 4; 95% CI: 1.82–8.83, p = 0.001) while a protective effect of IgG anti-cytomegalovirus (CMV) was observed (OR 0.3; 95%CI: 0.16–0.74, p = 0.009). Anti-Ro/SSA, anti-LA/SSB, anti-nuclear, anti-gliadin, anti-TTG-IgG and anti-RNP antibodies were statistically more prevalent among SS patients than controls. Notably, the presence of anti-Ro/SSA and anti La/SSB correlated with anti-EBVEA IgG (OR 3.1; 95%CI: 1.08–8.74) and (OR 3.9; 95%CI: 1.37–10.96) respectively. Autoantibodies, cytokines and several genetic markers correlated with clinical manifestation of SS. Our data suggest that infectious agents may play both a causative and protective role in the pathogenesis of SS. Moreover certain autoantibodies, cytokines and specific TAP alleles correlate with clinical manifestations of SS, and may enable better prediction and/or directed therapy once confirmed in future studies.

Conclusions

This is the first study regarding the outcome and mortality-related risk factors for PID patients requiring PICU admission. We suggest that PICU management is as important as early diagnosis and treatment for these patients. Prediction of those at risk for poorer outcome might be beneficial for accurate intensive care management and survival.
