Total IL-12 levels are increased in paediatric atopic dermatitis: correlations with age and disease severity.

Alterations in the immune response play an important role in the pathogenesis of atopic dermatitis (AD). We evaluated the role of Th1/Th2 cytokine imbalance in paediatric AD and its progression towards other allergic manifestations. The levels of total interleukin (IL)-12 (p70+p40), IL-12 p70 and soluble CD30 (sCD30) were measured in paediatric patients affected by AD and in age-matched, non-atopic subjects (controls).

Chimerism in a child with severe combined immunodeficiency: a case report.

Severe combined immunodeficiency (SCID) represents a group of rare, sometimes fatal, congenital disorders in which there is a combined absence of T-lymphocyte and B-lymphocyte function. Children with SCID die within two years of age, if untreated. The effective treatment for SCID is a hematopoietic stem cell transplantation (HSCT).

Identification of a novel HLA-A*02 allele, A*027401*.

A novel HLA-A*02 allele was detected in a Caucasian patient from central Italy, requiring a hematopoietic cell transplantation. Direct sequencing identified a variation in one nucleotide position, which was confirmed by cloning. The name A*027401 was officially assigned by the WHO Nomenclature Committee in November 2004.
