Primary immunodeficiency diseases (PID) are congenital disorders secondary to an impaired immune response. Infections, autoimmune disorders, atopy, and lymphoproliferative syndromes are commonly associated with this disorder. OBJECTIVE: To present and discuss 3 infants diagnosed with PID. CLINICAL CASES: The cases are presented of three patients with PID diagnosed during their first admission to a Paediatric Intensive Critical Care Unit. The first patient, a 4-month-old infant affected by a severe pneumonia, and was diagnosed as a Severe Combined Immunodeficiency Disease...

Primary antibody deficiencies (PAD) constitute the majority of all primary immunodeficiency diseases (PID) and immunoglobulin replacement forms the mainstay of therapy for many patients in this category. Secondary antibody deficiencies (SAD) represent a larger and expanding number of patients resulting from the use of a wide range of immunosuppressive therapies, in particular those targeting B cells, and may also result from renal or gastrointestinal immunoglobulin losses. While there are clear similarities between primary and secondary antibody deficiencies, there are also significant differences...

INTRODUCTION: Common variable immunodeficiency and X-linked agammaglobulinaemia are primary immunodeficiencies classified as antibody deficiencies, and they both result in hypogammaglobulinaemia. OBJECTIVE: Evaluate the lipid profile and other cardiovascular risk biomarkers in CVID and XLA patients. METHODS: In total, 24 patients and 12 healthy controls matched by age and gender were included in the study. We evaluated anthropometric measurements, and seric total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG), apo A-I, small dense LDL (sdLDL), C-reactive protein (CRP), and tumour necrosis factor alpha (TNF-alpha), myeloperoxidase (MPO), cholesteryl ester transfer protein (CETP), and lecithin cholesterol acyltransferase (LCAT) were assessed...

Fifty years ago, in 1964, our understanding of the immune system was very rudimentary. Gell and Coombs had just described classes of hypersensitivity reactions, and Bruton had described and commenced immunoglobulin replacement in agammaglobulinaemia. The distinction between T and B cells was not identified and characterised until the 1960s and 1970s. This was followed by increasing recognition of T and B cell collaboration in immune responses and identification of significant immunodeficiencies. CD4 and CD8 T cells were only recognised in the 1970s and 1980s...

Since its introduction as a public health programme in the United States in the early 1960s, newborn blood screening (NBS) has evolved from the detection of phenylalanine levels on filter paper to the application of DNA-based technologies to identify T-cell lymphopenia in infants with severe combined immunodeficiency. This latter use of NBS has required the development of an assay for T-cell lymphopenia based on the quantification of T-cell receptor excision circles (TRECs) that could be performed on dried blood spots routinely collected from newborn infants...

Chronic wounds are a rare complication of X-linked agammaglobulinaemia (XLA). Fastidious organisms such as helicobacter bills have been reported in XLA with chronic wounds but sterile chronic wounds also occur. Hyperbaric Oxygen Therapy has been used in chronic wounds but has not previously been reported in primary antibody deficiencies. We present a case of a chronic wound in a patient with XLA refractory to antimicrobial therapy that made a remarkable recovery following Hyperbaric Oxygen Therapy.

Granulomatous small bowel enteropathy is an unusual presentation associated with X-linked agammaglobulinaemia. We present a rare case of this condition that was further complicated by an enterocutaneous fistula and report our experience managing this condition successfully with infliximab, which has not been documented in the literature previously.

Hypogammaglobulinaemias are the most common primary immunodeficiency diseases. This group of diseases is very heterogeneous, and little is known about these diseases in children. In the Pediatric Predominantly Antibody Deficiencies (PedPAD) study, we analysed data from the European Society for Immunodeficiencies (ESID) online database to gain more insight into the characteristics of children with hypogammaglobulinaemia; 46 centres in 18 different countries agreed to participate. Data from 2076 of the 3191 children who were registered at the time of data extraction with a diagnosis of hypogammaglobulinaemia (this excludes agammaglobulinaemia and defects in class-switch recombination) were available for analysis...

BACKGROUND: X-linked agammaglobulinaemia (XLA) is a genetic disorder characterised by a defect in the generation of mature B cells, lack of antibodies production, and susceptibility to recurrent bacterial infections. Understanding of the risk factors responsible for morbidity and mortality in these patients can help in a better management of this disorder. However, there is a lack of specific studies in the literature regarding the morbidity and mortality of XLA patients. This study is designed to evaluate morbidities and mortality and survival rates in Iranian patients with XLA diagnosis during the past 20 years...

BACKGROUND: Antibody deficiency comprises a heterogeneous group of disorders characterised by the body's inability to mount an effective antibody response to pathogens. Although it has been reported that asthma and allergic disease are frequent in antibody deficiencies, there are no data that evaluate and compare bronchial hyperreactivity (BHR) in all groups of antibody deficiencies. In this study, we aimed to evaluate and compare the frequency of BHR in patients with different antibody deficiencies...

PURPOSE: Estimating the underlying demand for immunoglobulin (Ig) is important to ensure that adequate provision is made for patients with primary immune deficiency (PID) in the context of the competing demands for Ig and to ensure optimal therapeutic regimens. The concept of latent therapeutic demand (LTD) was used to estimate evidence-based requirements and compared to the actual Ig consumption in different countries. The estimates were performed for common variable immunodeficiency (CVID) and X-linked Agammaglobulinaemia (XLA), the two most commonly studied PIDs using Ig...

BACKGROUND: X-linked agammaglobulinaemia (XLA) is the most common inherited humoural immunodeficiency disorder. Mutations in the gene coding for Bruton's tyrosine kinase (BTK) have been identified as the cause of XLA. Most affected patients exhibit a marked reduction of serum immunoglobulins, mature B cells, and an increased susceptibility to recurrent bacterial infections. However, the diagnosis of XLA can be a challenge in certain patients who have near-normal levels of serum immunoglobulin...

Patients with agammaglobulinaemia and hypogammaglobulinaemia require immunoglobulin G (IgG) replacement therapy to prevent serious infections. Since the 1950s, therapy with human immune globulin products has been the standard of treatment. Currently, the most common routes of administration of IgG replacement therapy are intravenous (IVIG) or subcutaneous (SCIG). The home therapy may improve the quality of life in patients who require lifelong IgG replacement. The -anti-IgA antibody test identifies the patients with the risk of anaphylactoid reactions in IVIG replacement...

AIM: Primary immunodeficiencies (PID) are becoming a recognized public health problem worldwide. The most important subgroup of these disorders are the antibody deficiencies. X-linked agammaglobulinaemia was the first described entity of this group and is characterised by early onset of recurrent bacterial infections, profound deficiency of all immunoglobulin isotypes and markedly reduced number of peripheral B-lymphocytes. CASE REPORT: We report the case of a 10-year old boy with X-linked agammaglobulinaemia caused by a previously non-described mutation in BTK gene with typical clinical presentation but delayed diagnosis...

OBJECTIVES: To determine the prevalence of failure of transfer of passive immunity (FTPI) and agammaglobulinaemia in calves in south-west Victorian dairy herds and identify associated risk factors for both outcomes. DESIGN: Cross-sectional study. METHODS: Serum total protein was measured in 1018 calves from 100 south-west Victorian dairy herds. The proportions of calves with FTPI and agammaglobulinaemia were determined and logistic regression with random effects used to identify calf- and herd-level variables associated with both conditions...

We studied the association between coeliac disease and other diseases in a cohort of 896 persons who were registered in the Danish National Registry of Patients during a 16-year period. The registry contains information on all discharge diagnoses from Danish somatic hospitals. The total number of observation years in the cohort was 7144 years. The background population was 5.1 million.The strongest association was found with diabetes mellitus, pancreatic diseases and dermatitis herpetiformis. A weaker association was found with small intestinal cancer, malignant haematological disorders, agammaglobulinaemia and rheumatoid arthritis...

PURPOSE OF REVIEW: Technical possibilities to screen for inborn errors of immune function at the neonatal stage have been rapidly progressing, whereas the guidelines that apply for the evaluation of benefits and concerns on expanding screening panels have not been broadly discussed for primary immunodeficiency diseases (PID). This review reflects on the assessment of severe combined immunodeficiencies (SCID), primary agammaglobulinaemias (such as X-linked agammaglobulinaemia) and inherited haemophagocytic syndromes (such as familial haemophagocytic lymphohistiocytosis) to be included in newborn screening (NBS) programmes...
