A gain-of-function mutation of STAT1 in a 3-year-old child with chronic mucocutaneous candidiasis and autoimmune hepatitis: a case report
نویسندگان
چکیده
Background Chronic mucocutaneous candidiasis (CMC) is a heterogeneous group of primary immunodeficiency diseases (PID) characterized by chronic and recurrent infections of the skin, nails, and oropharynx, mostly caused by Candida sp. CMC is often associated with autoimmune and endocrine disorders. However, CMC may be the only or the main phenotype in patients with AD IL-17F and AR IL-17RA deficiencies, as well as gain-of-function (GOF) mutations of STAT1.

BACKGROUND Gain-of-function (GOF) mutations in the human signal transducer and activator of transcription 1 (STAT1) manifest in immunodeficiency and autoimmunity with impaired TH17 cell differentiation and exaggerated responsiveness to type I and II interferons. Allogeneic bone marrow transplantation has been attempted in severely affected patients, but outcomes have been poor. OBJECTIVE We s...
متن کاملA Novel Heterozygous Mutation in the STAT1 SH2 Domain Causes Chronic Mucocutaneous Candidiasis, Atypically Diverse Infections, Autoimmunity, and Impaired Cytokine Regulation
Chronic mucocutaneous candidiasis (CMC) is a primary immunodeficiency characterized by persistent or recurrent skin and mucosal surface infections with Candida species. Different gene mutations leading to CMC have been identified. These include various heterozygous gain-of-function (GOF) mutations in signal transducer and activator of transcription 1 (STAT1) that are not only associated with in...
متن کاملChronic mucocutaneous candidiasis caused by a gain-of-function mutation in the STAT1 DNA-binding domain.
Chronic mucocutaneous candidiasis (CMC) is a heterogeneous group of primary immunodeficiency diseases characterized by chronic and recurrent Candida infections of the skin, nails, and oropharynx. Gain-of-function mutations in STAT1 were very recently shown to be responsible for autosomal-dominant or sporadic cases of CMC. The reported mutations have been exclusively localized in the coiled-coil...
متن کاملRisks of Ruxolitinib in STAT1 Gain-of-Function-Associated Severe Fungal Disease
Heterozygous STAT1 gain-of-function (GOF) mutations are associated with chronic mucocutaneous candidiasis and a broad spectrum of infectious, inflammatory, and vascular manifestations. We describe therapeutic failures with the Janus Kinase (JAK) inhibitor ruxolitinib in 2 STAT1 GOF patients with severe invasive or cutaneous fungal infections.

Background: Para-amino benzoic acid (PABA) is an important ingredient used as a structure moiety in drugs with wide range of therapeutic uses; however, its safety and possible side effects in young children have not been determined. Case Presentation: An 8-year-old girl was admitted to the emergency department for paleness, jaundice, abdominal pain and nausea associated with Hemoglubin (Hb) =4...
