The infectious lymphocytosis is an independent viral disease with a passing considerable lymphocytosis in blood.
Epidemiology The infectious lymphocytosis occurs almost only among children.
Etiology and pathogeny Development of an infectious lymphocytosis is connected with Koksaki's virus, however it is impossible to exclude also etiological role of other viruses completely. A disease kontagiozno, its flashes in organized children's collectives are seldom observed. An incubation interval — from 12 to 21 days.
Classification Allocate the options of an infectious lymphocytosis proceeding with the easy catarral phenomena of upper respiratory tracts or a diarrhea and abdominal pains against characteristic changes of a gemogramma and miyelogramma.
Approximate formulation of the diagnosis: Infectious lymphocytosis with a passing leukocytosis, increase in quantity of lymphocytes in blood and marrow, korepodobny rash on skin.
Clinic Features of a clinical current of an infectious lymphocytosis are the slight catarral phenomena in upper respiratory tracts, sometimes a diarrhea with abdominal pains and in the right ileal area. Temperature normal or is slightly increased. At some patients skin rash of korepodobny character is noted. Lymph nodes, a spleen, a liver are not increased. In blood — a leukocytosis to 50 — 80*109/l and a zrelokletochny lymphocytosis, sometimes Gumprekht's shadows. In a miyelogramma the percent of lymphocytes is increased.
Verification of the diagnosis At adults the infectious lymphocytosis is differentiated from a chronic lymphoid leukosis. Fast normalization of a gemogramma allows to speak about an infectious lymphocytosis. At pains in the right ileal area it is necessary to exclude appendicitis.
Treatment At an infectious lymphocytosis do not apply any therapy, it proceeds several days or weeks and comes to an end with recovery.
