COVID-19 Vaccination Responses with Different Vaccine Platforms in Patients with Inborn Errors of Immunity. J Clin Immunol 2023; 43:271-285.

Abstract
Patients with inborn errors of immunity (IEI) in Argentina were encouraged to receive licensed Sputnik, AstraZeneca, Sinopharm, Moderna, and Pfizer vaccines, even though most of the data of humoral and cellular responses combination on available vaccines comes from trials conducted in healthy individuals. We aimed to evaluate the safety and immunogenicity of the different vaccines in IEI patients in Argentina. The study cohort included adults and pediatric IEI patients (n = 118) and age-matched healthy controls (HC) (n = 37). B cell response was evaluated by measuring IgG anti-spike/receptor binding domain (S/RBD) and anti-nucleocapsid(N) antibodies by ELISA. Neutralization antibodies were also assessed with an alpha-S protein-expressing pseudo-virus assay. The T cell response was analyzed by IFN-γ secretion on S- or N-stimulated PBMC by ELISPOT and the frequency of S-specific circulating T follicular-helper cells (TFH) was evaluated by flow cytometry.No moderate/severe vaccine-associated adverse events were observed. Anti-S/RBD titers showed significant differences in both pediatric and adult IEI patients versus the age-matched HC cohort (p < 0.05). Neutralizing antibodies were also significantly lower in the patient cohort than in age-matched HC (p < 0.01). Positive S-specific IFN-γ response was observed in 84.5% of IEI patients and 82.1% presented S-specific TFH cells. Moderna vaccines, which were mainly administered in the pediatric population, elicited a stronger humoral response in IEI patients, both in antibody titer and neutralization capacity, but the cellular immune response was similar between vaccine platforms. No difference in humoral response was observed between vaccinated patients with and without previous SARS-CoV-2 infection.In conclusion, COVID-19 vaccines showed safety in IEI patients and, although immunogenicity was lower than HC, they showed specific anti-S/RBD IgG, neutralizing antibody titers, and T cell-dependent cellular immunity with IFN-γ secreting cells. These findings may guide the recommendation for a vaccination with all the available vaccines in IEI patients to prevent COVID-19 disease.

Abstract
Small molecule inhibitors targeting dysregulated pathways (RAS/RAF/MEK, PI3K/AKT/mTOR, JAK/STAT) have significantly improved clinical outcomes in cancer patients. Recently Bruton's tyrosine kinase (BTK), a crucial terminal kinase enzyme in the B-cell antigen receptor (BCR) signaling pathway, has emerged as an attractive target for therapeutic intervention in human malignancies and autoimmune disorders. Ibrutinib, a novel first-in-human BTK-inhibitor, has demonstrated clinical effectiveness and tolerability in early clinical trials and has progressed into phase III trials. However, additional research is necessary to identify the optimal dosing schedule, as well as patients most likely to benefit from BTK inhibition. This review summarizes preclinical and clinical development of ibrutinib and other novel BTK inhibitors (GDC-0834, CGI-560, CGI-1746, HM-71224, CC-292, and ONO-4059, CNX-774, LFM-A13) in the treatment of B-cell malignancies and autoimmune disorders.

Abstract
Btk plays crucial roles in the differentiation and activation of B and myeloid cells. Despite drastic reductions of other Ig isotypes, paradoxically high IgE responses have been known in btk mutant mice. Here we show that btk(-/-) dendritic cells exhibit a more mature phenotype and a stronger in vitro and in vivo T cell-stimulatory ability than wild-type cells. Increased IgE responses were induced by adoptive transfer of btk(-/-) dendritic cells into mice. Consistent with the stronger T cell-stimulatory ability of btk(-/-) dendritic cells, btk(-/-) mice exhibited enhanced inflammation in Th2-driven asthma and Th1-driven contact sensitivity experiments. These negative regulatory functions of Btk in dendritic cells appear to be mediated mainly through autocrine secretion of IL-10 and subsequent activation of Stat3.

Abstract
Otolaryngologists are frequently consulted to manage infectious and noninfectious complications of immune deficiency. Although defects of host defense and recurrent or severe infections are the most obvious manifestations of immune deficiency, patients are often at increased risk for autoimmune and malignant disease as well. Knowledge of primary and acquired immune deficiencies will facilitate appropriate identification, treatment, and referral of patients with these defects. When immunodeficiency is known or suspected, it is particularly important to have a high index of suspicion for unusual or severe manifestations of infection, to have a low threshold for obtaining imaging to aid in diagnosis, and to treat infections for longer periods of time with higher doses of antibiotic. Surgery may be required for definitive treatment of infections that do not respond to medical therapy and for management of complications of infectious disease

Abstract
X-linked agammaglobulinaemia (XLA) is a primary immunodeficiency disease characterized by very low levels or even absence of circulating antibodies. The immunological defect is caused by deletions or mutations of Bruton's tyrosine kinase gene (Btk), whose product is critically involved in the maturation of pre-B lymphocytes into mature B cells. Btk is expressed not only in B lymphocytes but also in cells of the myeloid lineage, including dendritic cells (DC). These cells are professional antigen presenting cells (APC) that play a fundamental role in the induction and regulation of T-cell responses. In this study, we analysed differentiation, maturation, and antigen-presenting function of DC derived from XLA patients (XLA-DC) as compared to DC from age-matched healthy subjects (healthy-DC). We found that XLA-DC normally differentiate from monocyte precursors and mature in response to lipopolysaccharide (LPS) as assessed by de novo expression of CD83, up-regulation of MHC class II, B7.1 and B7.2 molecules as well as interleukin (IL)-12 and IL-10 production. In addition, we demonstrated that LPS stimulated XLA-DC acquire the ability to prime naïve T cells and to polarize them toward a Th1 phenotype, as observed in DC from healthy donors stimulated in the same conditions. In conclusion, these data indicate that Btk defect is not involved in DC differentiation and maturation, and that XLA-DC can act as fully competent antigen presenting cells in T cell-mediated immune responses.

Abstract
X-linked agammaglobulinemia (XLA) is a primary immunodeficiency of the B-cell compartment caused by a defective gene encoding for the tyrosine kinase (btk) essential for B cell differentiation. Affected males undergo recurrent pyogenic infections and deficient immunoglobulin production. Peripheral blood T cells from 6 XLA patients and 6 matched healthy controls were stimulated with either PHA or tetanus toxoid (TT) and T cell clones obtained were compared for their cytokine profile. In the series of PHA-induced or TT-specific CD4(+) T cell clones derived from XLA patients, the Th1 profile was predominant (63 and 65 %, respectively). Upon stimulation with TT, the proportion of activated T cells from XLA that expressed the IFN-gamma -associated LAG-3 activation molecule was higher than in control T cells (51 vs. 25 %), whereas the expression of the IL-4-associated CD30 molecule was lower (5 vs. 21 %). In a cohort of 31 XLA patients, plasma levels of soluble (s)LAG-3 and sCD30, chosen as indirect indicators of the Th1 / Th2 activity in vivo, were significantly higher and lower, respectively, than those measured in 31 healthy controls. Likewise, plasma levels of interferon-inducible protein 10 and of macrophage-derived chemokine in XLA patients were significantly higher and lower, respectively, than in healthy controls.

Abstract
Children with IgG2 deficiency commonly develop recurrent acute otitis media. It is believed that these infections are secondary to impaired antibody response rather than eustachian tube dysfunction and are therefore less responsive to treatment with tympanostomy tubes. The authors compared the incidence of acute otitis media in IgG2-deficient patients following tympanostomy tube placement with controls in a retrospective cohort study. The charts of 20 patients (10 with IgG2 deficiency and 10 controls) were reviewed. Episodes of otitis media were recorded for 12 months. IgG2-deficient patients experienced three times as many occurrences of otitis media as did controls. This suggests that otitis media is much more common in these patients following tympanostomy tube placement. We believe that an immunodeficiency workup should be considered in patients with multiple episodes of otitis media following placement of tympanostomy tubes.

Abstract
The transcription pattern of the heavy chain immunoglobulin gene locus was analyzed in a 6-month-old female with agammaglobulinemia characterized by the absence of mature B cells in peripheral blood, arrested B cell development in the bone marrow and lack of germinal center development. DNA sequencing provided no evidence of mutations within the coding region of the Bruton's tyrosine kinase gene. Polymerase chain reaction-generated cDNA libraries from blood and bone marrow were screened initially using JH and CH oligodeoxynucleotide probes and VH family-specific probes. Only 10% of the transcripts constituted mature VDJC mu recombinations. Ninety percent of the cDNA were sterile immunoglobulin transcripts comprised of: DJC mu (DH-JHC mu), JC mu (JH-C mu), EC mu (enhancer spliced to C mu), SC mu and IC mu [corresponding to switch (S) and intron (I) regions spliced to C mu]. In the mature immunoglobulin transcripts, VH use indicated germline expression with little evidence of somatic mutation. All cDNA were of the C mu type. Different D segments, D-D joining events and unknown D-like elements were noted in the DJC mu and VDJC mu transcripts. This pattern of immunoglobulin rearrangements, along with the phenotypic cell surface antigen characteristics (CD19-), suggest that an earlier arrest in B cell development than is characteristic of Bruton's X-linked agammaglobulinemia has occurred in this patient.

Abstract
In the 40 years since Ogden Bruton discovered agammaglobulinemia, more than 50 additional immunodeficiency syndromes have been described. Until recently, there was little insight into the fundamental problems underlying a majority of these conditions. Recently, however, the molecular bases of three X-linked immunodeficiency disorders have been reported. These include X-linked immunodeficiency with hyper IgM, X-linked agammaglobulinemia, and X-linked severe combined immunodeficiency. These remarkable accomplishments have been made possible through a combination of new knowledge of molecular signaling mechanisms between and within cells of the immune system and greatly improved approaches to disease loci mapping within the human genome. Improvements in the therapy of immunodeficiency diseases have been impressive, and the development of generally safe and effective intravenous immunoglobulin preparations and T cell depletion techniques that permit the use of non-HLA-identical bone marrow donors have been the most important advances over the past 14 years. The identification and cloning of the genes for several of the primary immunodeficiency diseases have obvious implications for potential future somatic cell gene therapy for these patients. The rapidity of these advances suggests that soon there will be many more to come.

Abstract
X-linked agammaglobulinemia (XLA) is an immunodeficiency disease in man, resulting from an arrest in early B cell differentiation. The gene defective in XLA has recently been identified and encodes a cytoplasmic protein tyrosine kinase, named Bruton's tyrosine kinase (btk), essential for cell differentiation and proliferation at the transition from pre-B to later B cell stages. In this study we investigated btk expression by Northern blotting experiments in a series of human (precursor-) B cell lines, acute lymphoblastic leukemias and plasmacytomas. btk was found to be already expressed in very early stages of B cell differentiation, even prior to immunoglobulin (Ig) heavy (H) or light (L) chain gene rearrangements. Transcripts were also detected at the pre-B cell stage and in mature B cells, irrespective of the Ig H chain class expressed. Approximately at the transition from mature B cells to plasma cells, expression of the btk gene is down-regulated. In addition, the btk gene was found to be expressed in myeloid cell lines and acute myeloid leukemias. btk expression in myeloid cells is probably not a prerequisite for myeloid differentiation, since myeloid cells in XLA patients seem not to be affected. No btk expression was found in T-lineage cells. The btk expression profile, i.e. from early precursor-B cell stages preceding Ig rearrangement up to mature B cells, supports the hypothesis that the XLA defect resides in a critical step of B cell development which is independent of the Ig gene recombination machinery.

Abstract
X-linked agammaglobulinemia (XLA) is a humoral immunodeficiency disease in man, characterized by an arrest in B lymphocyte differentiation at the precursor B cell stage. The structure of expressed immunoglobulin (Ig) kappa light (L) chain rearrangements of nine B lymphoblastoid cell lines from one XLA patient was investigated by amplification of cDNA by the polymerase chain reaction using 5' V kappa family-specific primers and a 3' kappa constant region primer. Members of all four V kappa gene families were found to be utilized in Ig kappa L chain rearrangements at frequencies that were consistent with random V kappa family usage. There was no preference for usage of any particular kappa joining segment. Additional diversity was generated by deletions and random nucleotide insertions at the site of juxtaposition. Particular V kappa members seemed to be overrepresented in the sample. The observed homology of the V kappa I, V kappa II and V kappa III region sequences, both to each other and to known germ-line V kappa sequence indicated the absence of somatic mutations in the majority of these expressed Ig genes. In contrast of the single-member V kappa IV family four different sequences were found to be expressed. That these sequences were mutated derivatives of a germ-line V kappa IV element was substantiated both by sequence analysis and oligonucleotide hybridization. This finding shows that the mutation process can occur in early stages of B cell development i.e. before H chain class switch has occurred. The presence of these mutations is probably independent of clonal expansion since XLA patients are unable to respond to antigen. We conclude that the differentiation arrest in XLA does not preclude early onset of somatic mutation events in V kappa gene segments.
