Immunoglobulin A-antigliadin antibodies and total immunoglobulin A wer
e assessed on serum samples from 52 children infected by Human Immunod
eficiency Virus (HIV). Titers of antigliadin antibodies exceeding the
normal range were found in 14 children (27%). No statistically signifi
cant difference was observed either between children with symptomatic
or asymptomatic infection, or among children with different degrees of
immunosuppression. Though total immunoglobulin A concentration increa
sed with the progression of the disease, no significant correlation wa
s found between antigliadin antibodies and total immunoglobulin A. Mea
n antigliadin titers showed no significant difference between children
with or without chronic gastrointestinal complaints. These findings s
uggest that, although a raised immunoglobulin A-antigliadin activity i
s a common feature of children infected by HIV, this is not merely the
consequence of elevated total immunoglobulin A concentration. Moreove
r, in these children a raised antigliadin antibody titer should not be
regarded as a reliable marker either of disease progression or of int
estinal mucosa(1) damage.
