A severe ABCC6-induced generalized arterial calcification of infancy overshadowed by the EGFR-associated neonatal inflammatory skin and bowel disease 2 in a Roma girl.

Neonatal inflammatory skin and bowel disease 2 is an epidermal growth factor receptor (EGFR)-associated autosomal recessive early-infantile disease with inflammatory skin, alopecia, progeroid features, electrolyte imbalance, recurrent infections, and premature death. Pseudoxanthoma elasticum (PXE) is another autosomal recessive skin disorder with some ocular and cardiovascular alterations, caused by variations in the ATP binding cassette subfamily c member 6 (ABCC6) gene. However, ABCC6-deficiency is, rarely, also presented as as an early/late-infantile autosomal recessive generalized arterial calcification of infancy.

Successful treatment of severe allergic asthma with omalizumab in a girl with DiGeorge syndrome.

DiGeorge syndrome (DGS) is a primary immunodeficiency disease characterized by multiple clinical features, including congenital heart defects, typical facial appearance, hypocalcemia, and immunodeficiency associated to thymic hypoplasia. A subset of patients with DGS may also have contemporary allergic diseases, possibly in the context of T cell dysregulation. Our work presents an unusual case of DGS in coincidence with severe allergic asthma successfully treated by humanized monoclonal anti-IgE antibody, omalizumab.
