Autosomal-recessive hyper-IgE syndrome (AR-HIES) is a combined immunodeficiency recently found to be associated with mutations of DOCK8. Clinically, this disorder is characterized beside recurrent bacterial complications, in particular by an unusual susceptibility to extensive cutaneous viral complications and by a high risk for squamous cell carcinoma.(More)
Mutations in the adenosine deaminase (ADA) gene are responsible for a form of severe combined immunodeficiency (SCID) caused by the lymphotoxic accumulation of ADA substrates, adenosine and 2'-deoxy-adenosine. The molecular mechanisms underlying T-cell dysfunction in humans remain to be elucidated. Here, we show that CD4(+) T cells from ADA-SCID patients(More)
We report on 12 patients with chronic granulomatous disease transplanted with hematopoietic stem cells from matched unrelated (n = 9) or matched sibling donors (n = 3). The most common infectious complication was pulmonary aspergillosis, which nine patients had previously developed. Only 5 of 12 individuals had normal lung function prior to transplantation.(More)
In this report, we present an analysis in 39 WAS patients treated by hematopoietic stem cell transplantation (HSCT) in our center since 1983. Fifteen patients received transplants from HLA-identical unrelated donors, 15 from nonidentical parental donors, and 9 from matched siblings. The overall survival rate is 90% in patients with matched donors and 50% in(More)
Conventional MHC-restricted T lymphocytes leave thymus with a naive phenotype and require Ag-dependent stimulation coupled to proliferation to acquire effector functions. Invariant (i)NKT cells are a subset of T lymphocytes considered innate because they display an effector memory phenotype independent of TCR stimulation by foreign Ags. We investigated the(More)
We are reporting on a 7-months-old boy with suspected hyper-IgE syndrome, presenting with a therapy resistant severe eczema and an overall reduction of in vitro cytokine production. Interferon-alpha (IFN-alpha) treatment resulted in a marked and stable clinical improvement and normalization of in vitro T-cell cytokine production, indicating a valid(More)
