· Neonatal screening for primary immunodeficiency diseases (PIDs) enables early diagnosis and subsequent initiation of therapy. · Excision of T-cell receptors and kappa-recombination excision circles are cheaper alternative PID screening methods. · Sanger DNA sequencing remains the reference method for detecting PID; however, next-generation sequencing technology is increasingly used to diagnose it. · Here we developed a graphical algorithm for diagnosing primary immunodeficiency syndrome based on modern methods of screening for primary immunodeficiencies in newborns. |
In this article, a systematic review of reported primary immunodeficiency disease (PID) cases in Korea was performed and we attempted to estimate the number of PID patients and healthcare costs for the first time in Korea. Our review revealed that Korean PID cases are greatly underreported in the literature based on health insurance. Physicians in the field and health care policymakers should be aware of the disease burden of PID. |
X-linked agammaglobulinemia (XLA) is a hereditary humoral immunodeficiency that results from Bruton’s tyrosine kinase ( |
Hyperimmunoglobulin E syndrome (HIES) is a rare immunodeficiency disease which is characterized by high serum IgE levels, eczema, and recurrent infections. Herein we present the case of a patient with HIES associated with STAT3 gene (stat3) mutation. A 16 year-old girl was admitted to our hospital due to hemoptysis caused by pneumonia with bronchiectasis. She had a history of recurrent... |
The major function of immune system is to protect infections. The immune systems are composed of innate and adaptive immunity. In adaptive immunity, the cellular and humoral components interact each other. Neonates and infants are infected frequently, because immune systems are naive and easy to expose to infectious agents. The complete history and physical examination is essential to evaluate the... |
The generation of a draft sequence of the human genome has lead to an opportunity to characterize human diversity, including the differences in host response to numerous pathogens. Host responses upon exposure to a pathogen can determine the wide spectrum of illness from subclinical or mild to severe diseases. Host factors, particularly genetic backgrounds, influence the pathogenesis of infectious diseases.... |
Primary immunodeficiency diseases result from innate defects of immune system. As a consequence, recurrent viral, bactrial, fungal, and protozoal infections of varying severity ensue. Although primary immunodeficiency diseases are relatively rare, intensive study of these disorder has expanded our understanding of immunity. Recent progress in immunobiology and genetics has identified the causes of many of the primary immunodeficiency diseases. Diagnosis... |
Common variable immunodeficiency(CVID) is a heterogeneous immunodeficiency syndrome characterized by hypogammaglobulinemia, recurrent bacterial infections, and a variety of immunological abnormalities. We report a 10-year-old boy diagnosed with CVID and a fatal case of measles. He was admitted for fever, cough, conjunctival injection with purulent discharge and maculopapular rash with some scattered pinpoint sized petechial lesions on the whole body for... |
Five to fifteen percent of patients affected by human immunodeficiency virus(HIV) are children in developing countries. In Korea, most of HIV infections in children have been transfusion-related, and cases of vertical transmission have been very rare so far and are usually suspected due to a maternal positive history. We experienced a case of vertical transmission of HIV in a 19... |
Purpose : Microdeletion of chromosome 22q11.2 are associated with DiGeorge syndrome(DGS), velocardiofacial syndrome(VCFS) and conotruncal anomaly face syndrome(CTAFS). DGS was originally described as an immunodeficiency disorder secondary to impaired T cell production due to thymic aplasia or hypoplasia. But the frequency & severity of immunodeficiency of other clinical syndromes associated with the chromosome 22q11 deletion has not been investigated. This... |
Common variable immunodeficiency(CVID) is a heterogeneous collection of disorders with hypogammaglobulinemia with recurrent bacterial infections and high incidence of autoimmune disorders as its hallmark. We report a 7-year-old girl suffering from CVID with Coombs' test positive hemolytic anemia. She had been relatively well until 23-months old when she was admitted to Taejon St. Mary' s Hospital with pneumonia 5 years ago. Afterwards, she had... |
Nezelof's syndrome(combined immunodeficiency with immunoglobulin) is a hereditary primary immunodeficiency characterized by recurrent chronic pulmonary infections, oral and cutaneous candidiasis, failure to thrive, chronic diarrhea, skin infection, urinary tract infection, gram-negative sepsis, severe progressive varicella infection, lymphopenia, diminished lymphoid tissue, abnormal structure of the thymus, and presence of normal or increased levels of one or more of the major immunoglobulin classes, but with impaired antibody... |
Severe combined immunodeficiency disease is caused by a group of genetic disease characterized by abnormal function of T and B lymphocytes. The treatment of choice for severe combined immunodeficiency disease is a HLA mached bone marrow transplant, but transplantation of cultured thymus epithelium was used to treat severe combined immunodeficiency disease in case of that mached, related bone... |
Acquired persistent cytomegalovirus infection was diagnosed by anti CMV antibody and lymph node biopsy and persisted in a 3-year-old boy with recurrent episode of high fever, lymphadenopathy hepatosplenomegaly and pneumonia. Initial immunologic abnormalities including low serum IgG, high IgM decreased T4 and T4/T8 ratio finally progressed to immunologic paralysis which was compatible to common variable immunodeficiency. This is the first case which... |
Common variable immunodeficiency, as defined by World Health Organization classification of primary immunodeficiency, is a heterogenous group of disorders with hypogammaglobulinemia, decreased ability to produced antibody following antigenic challenge, and increased incidence of infections. The disorder was often familial, but no mode of inheritance has been discerned. Clinical fingings are recurrent bacterial infections, particularly respiratory infection. Laboratory evaluations in common variable immunodeficiency demonstrate decrease in... |
The immunodeficiency disorders are a diverse group of illness which results from defectsin one or more of the four major mechanisms of immune system-antibody-mediated(B cell) immunity, cell-mediated(T cell) immunity, phagocytosis, and complements. Though immunodeficiency disorders are uncommon, the possibility should be considered in any individuals with recurrent or persistent infection. During the period between January, 1973 and October, 1984, we... |
