Two hundred and thirty four cases of children with a history of prolonged febrile illnesses or repeated infectious processes were studied from November 1968 through March 1974 in order to search for humoral immune deficiencies. Four to ten percent had transitory IgG deficiency; five to twenty one percent had IgA deficiency and one to four percent had IgG-IgA combined deficiency. No adequate explanation can be given to the slight discrepancy between the prevalence noticed in the two periods of the study conducted: 1968-1972 and 1972-1974. On the other hand, immunoglobulin levels abnormalities were noticed among kindred of patients, and the authors suggest this may represent a genetic etiology, for the abnormalities found.
