Kawasaki Disease (KD) is a systemic autoimmune vasculitis that affects small and medium sized vessels. Main complication of Kawasaki Disease is coronary artery aneurism, which has higher risk in case of delayed diagnosis and treatment. Although, complete and incomplete KD cases in different types of immune deficiency diseases have been presented up to date, clinical course of KD in patients with hypogammaglobulinemia (HG) has not been reported. Herein, a case diagnosed as incomplete KD in a child with transient HG of infancy has been reported...

OBJECTIVE: Rituximab (RTX) is an anti-CD20 monoclonal antibody that selectively depletes B-cell population. Thus, it presents a potential risk for the development of hypogammaglobulinemia and related infectious events. Our aim was to identify predictors of hypogammaglobulinemia in RA patients long-term treated with RTX. METHODS: Multicenter observational usual care study of patients with RA on RTX maintenance therapy (minimal exposition of 30 months). Serum protein electrophoresis was performed before each RTX infusion...

Monoclonal gammopathies are a rare diagnosis in pediatric patients. A 19-year-old female patient with past medical history of hypogammaglobulinemia and natural killer cell deficiency and stage III follicular lymphoma, in remission, presented with a right-sided pneumonia, noted to have acute kidney injury and proteinuria. Complement C3 and C4 levels were normal. Anti-double-stranded DNA antibodies, antinuclear antibodies, anti-extractable nuclear antigen antibodies, and antineutrophil cytoplasmic antibodies were negative...

Good's syndrome, the adult onset hypogammaglobulinemia associated with thymoma has been explained about six decades ago. It generally presents with recurrent infections and several paraneoplastic syndromes including myasthenia gravis, pure red cell aplasia, connective tissue disorders, superior vena cava, Horner's syndrome, lichen planus and inflammatory bowel disease. Lack of B cell, dysfunction of T cell, CD4+ T cell lymphopenia, reversed CD4/CD8+ T cell ratio, autoantibodies against Th17 related cytokines have been respected as the pathogenesis of the immune dysregulation this syndrome...

B-cell depleting anti-CD20 monoclonal antibody therapies are being increasingly used as long-term maintenance therapy for neuroinflammatory disease compared to many non-neurological diseases where they are used as remission-inducing agents. While hypogammaglobulinaemia is known to occur in over half of patients treated with medium to long-term B-cell-depleting therapy (in our cohort IgG 38, IgM 56 and IgA 18%), the risk of infections it poses seems to be under-recognised. Here, we report five cases of serious infections associated with hypogammaglobulinaemia occurring in patients receiving rituximab for neuromyelitis optica spectrum disorders...

High-count monoclonal B cell lymphocytosis (MBL) with a chronic lymphocytic leukemia (CLL) phenotype is a well-known entity, featuring 1-4% annual risk of progression towards CLL requiring treatment. Lymphoma-like MBL (L-MBL), on the other hand, remains poorly defined and data regarding outcome are lacking. We retrospectively evaluated 33 L-MBL cases within our hospital population and compared them to 95 subjects with CLL-like MBL (C-MBL). Diagnoses of L-MBL were based on asymptomatic B cell clones with Matutes score < 3, B cells < 5...

Genetic defects of NKX2-1 are classically associated with hypothyroidism, benign chorea and neonatal respiratory distress. The purpose of this study was to identify the genetic pathogenesis of the "NKX2-1 triad" in a 10 year-old female presenting additional features barely described in the disorder. In the neonatal period, she presented with generalized hypotonia and respiratory distress, with later episodes of frequent wheezing. At 3 month-age developmental dysplasia of the hip was diagnosed and at 10 months, primary hypothyroidism was detected and treated...

Pulmonary alveolar proteinosis (PAP) is characterized by accumulation of a surfactant-like substance in alveolar spaces and hypoxemic respiratory failure. Genetic PAP (GPAP) is caused by mutations in genes encoding surfactant proteins or genes encoding a surfactant phospholipid transporter in alveolar type II epithelial cells. GPAP is also caused by mutations in genes whose products are implicated in surfactant catabolism in alveolar macrophages (AMs). We performed whole-exome sequence analysis in a family affected by infantile-onset PAP with hypogammaglobulinemia without causative mutations in genes associated with PAP: SFTPB, SFTPC, ABCA3, CSF2RA, CSF2RB, and GATA2...

Although small prior studies have suggested that IgE can be low in common variable immunodeficiency (CVID), the workup for patients with recurrent infections and suspected hypogammaglobulinemia does not include the routine measurement of serum IgE. We sought to test the hypothesis that low/undetectable serum IgE is characteristic of CVID by comparing the frequency of low/undetectable serum IgE in healthy controls and patients with CVID. We measured total serum IgE in a large multi-center cohort of patients with CVID (n = 354) and compared this to large population-based cohorts of children and adults...

BACKGROUND: Roifman syndrome is a rare inherited disorder characterized by spondyloepiphyseal dysplasia, growth retardation, cognitive delay, hypogammaglobulinemia and, in some patients, thrombocytopenia. Compound heterozygous variants in small nuclear RNA gene RNU4ATAC, necessary for U12-type intron splicing, were recently identified to drive Roifman syndrome. OBJECTIVE: We studied three patients from two unrelated kindreds harboring compound heterozygous or homozygous stem II variants in RNU4ATAC to gain insights in the mechanisms behind this disorder...

RATIONALE: Cervical necrotizing fasciitis (CNF) and descending necrotizing mediastinitis (DNM) are rare forms of complication of Ludwig angina. These potentially lethal infections are difficult to recognize in early stages and are often associated with predisposing factors like diabetes and immunocompromised states. Moreover, IgG hypogammaglobulinemia (hypo-IgG) is considered to be a risk factor of mortality in patients with septic shock; however, it is not routinely quantified in patients with extremely serious infections, particularly in cases with no history or evidence of immunocompromising disorders...

Levetiracetam (LEV) is a second-generation antiepileptic drug approved for the treatment of several types of epilepsy. We report a 45-year-old female who developed hypogammaglobulinemia and B cell aplasia during LEV treatment. The Naranjo probability score for an adverse drug reaction was 6. After LEV discontinuation, the number of B cells gradually increased and reached normal levels within two months. This case suggests that monitoring of immunoglobulin levels and lymphocyte subsets analysis is important in patients treated with LEV, especially in cases of prolonged infections...

BACKGROUND/PURPOSE: Common variable immunodeficiency (CVID) is typically characterized by hypogammaglobulinemia and often but not always recurrent infections. Paradoxically, 8-22% of patients with CVID develop granulomatous disease. Granulomata have been described in many organs including the lungs, skin, liver, spleen, kidneys, eyes, lymph nodes, and intestines. Data about central nervous system (CNS) involvement in CVID are extremely rare. We aim to describe a case series and include an extensive literature review of CNS involvement in CVID to understand the different features and patterns of the disease...

Primary immunodeficiencies (PIDs) are low-incidence diseases caused by defects in genes involved in the development, maintenance, and regulation of the immune system. Common variable immunodeficiency (CVID) is the most common symptomatic immunodeficiency of adulthood. It has an approximate prevalence of 1 in 25 000-50 000 in the general population, with a delay in diagnosis between 6-7 years. The clinical manifestations of CVID constitute six main categories: infections, pulmonary complications, granulomatous or polyclonal lymphocytic disease, autoimmunity, gastrointestinal diseases and malignancy Most patients must have at least one of the following clinical manifestations (infection, autoimmunity, lymphoproliferation)...

Primary immunodeficiency disorders (PIDs) render patients vulnerable to infection with a wide range of microorganisms and thus provide good in vivo models for the assessment of immune responses during infectious challenges. Priming of the immune system, especially in infancy, depends on different environmental exposures and medical practices. This may determine the timing and phenotype of clinical appearance of immune deficits as exemplified with early exposure to Bacillus Calmette-Guérin (BCG) vaccination and dissemination in combined immunodeficiencies...
