Interleukin-12 receptor beta1 deficiency presenting as recurrent Salmonella infection.
We describe a child with interleukin-12 receptor beta1 (IL-12Rbeta1) deficiency caused by a homozygous IL12RB1 large deletion who presented at the age of 1 year with recurrent, often asymptomatic episodes of bacteremia caused by group D Salmonella species. No mycobacterial disease or other unusual infection was present. The episodes of salmonellosis were caused by an identical serovar during a ...
متن کاملInterleukin 12 deficiency associated with recurrent infections.
A 3-yr-old female patient exhibited interleukin 12 (IL-12) deficiency that was associated with recurrent episodes of pneumococcal pneumonia with sepsis and other infections in the absence of fevers. The patient's peripheral blood mononuclear cells (PBMCs) exhibited normal proliferative responses to antigens. Immune responses, including in vivo production of antibodies to diphtheria, tetanus, or...
متن کاملLow Penetrance, Broad Resistance, and Favorable Outcome of Interleukin 12 Receptor β1 Deficiency
The clinical phenotype of interleukin 12 receptor beta1 chain (IL-12Rbeta1) deficiency and the function of human IL-12 in host defense remain largely unknown, due to the small number of patients reported. We now report 41 patients with complete IL-12Rbeta1 deficiency from 17 countries. The only opportunistic infections observed, in 34 patients, were of childhood onset and caused by weakly virul...
متن کاملInherited interleukin 12 deficiency in a child with bacille Calmette-Guérin and Salmonella enteritidis disseminated infection.
Interferon-gamma receptor ligand-binding chain (IFN-gammaR1) or signaling chain (IFN-gammaR2) deficiency, like interleukin 12 receptor beta1 chain (IL-12Rbeta1) deficiency, predispose to severe infections due to poorly virulent mycobacteria and salmonella. A child with bacille Calmette-Guérin and Salmonella enteritidis infection was investigated. Mutations in the genes for IFN-gammaR1, IFN-gamm...
متن کاملInterleukin 12 receptor deficiency in a child with recurrent bronchopneumonia and very high IgE levels
Interleukin-12 (IL-12) is involved in cellular immune responses against intracellular pathogens by promoting the generation of T naive in T helper 1 (Th1) cells and by increasing interferon-gamma (IFN-gamma) production from T and natural killer (NK) cells. A defective induction of a Th1 response may lead to a higher risk of infections, and, in particular, infections due to typical and atypical ...
