Gastrointestinal and nutritional problems in children with immunodeficiency and AIDS.

Immunodeficient children pose a challenge to clinicians because of the interrelationship between infectious disease, metabolism, gastrointestinal tract function, psychosocial problems, and immune function. The interplay between these factors is not always clear, and frequently the best course of therapy is obscured because of an inability to determine which factors have the greatest impact on child health. To optimize therapeutic intervention, a multidisciplinary health care team must be involved with the management of children and their families.
