[Dynamics of antihemagglutinine (inhibitors and antibodies) to influenza virus in children with acute leukemia concurrently with influenza]. / Dinamika antigemaggliutininov (ingibitorov i antitel) k virusu grippa u detei s ostrym leikozom pri grippoznoi infektsii.

The study on the dynamics of some aspects of humoral immunity to influenza in children with acute leukosis in the presence of intercurrent influenza infection revealed two kinds of changes: a decline of a comparatively high initial level of antibody and inhibitors, and a rise in their titres when the initial level was lower. Both kinds of changes are characteristic both of the acute stage and the remission of acute leukosis. The chemotherapeutic treatment exerted no visible effect either on the level of the dynamics curve or on the pattern of serological shifts after influenza infection. These results suggest that in children with acute leukosis the response to influenza infection, being no different in nature from that in subjects not suffering from leukosis, is still poor quantitatively.
