Gastrointestinal manifestations of primary immune deficiencies in children

ABSTRACT

Primary immune deficiencies (PID) in children are a rare but serious group of genetic disorders of the immune system which apart from the host's defenses, can also affect every system of the human body, including the gastrointestinal tract. In their severe form they can lead to increased susceptibility to serious infections during infancy and even death. In the less severe form, they can present later in childhood or adolescence with subtle signs and symptoms. As PID can often mimic gastrointestinal diseases, children presenting with atypical gastrointestinal disease and/or failure to respond to conventional therapy should be evaluated for an underlying primary immune disorder and initiated appropriate treatment. The current review of the literature will summarize the gastrointestinal manifestations of primary immune deficiencies in children.
