Deficient Anterior Pituitary With Common Variable Immune Deficiency (David Syndrome): A New Case and Literature Reports

The document discusses a study on Deficient Anterior Pituitary with Common Variable Immune Deficiency (DAVID) syndrome, a rare condition caused by heterozygous mutations of the NFKB2 gene. The study involved a new case of a 7-year-old boy and a review of 28 other cases. The syndrome is characterized by adrenocorticotropic hormone (ACTH) deficiency, hypogammaglobulinemia, and recurrent infections. Alopecia was noted in 44% of the patients. All patients had mutations at the 3′end of the NFKB2 gene. The study concludes that DAVID syndrome is characterized by recurrent infections, autoimmune manifestations including alopecia, and hormone deficiencies, particularly ACTH deficiency. The study also recommends regular screening for anterior hypopituitarism in patients with NFKB2 variants.
