This state develops owing to is long the repeating small bleedings. Chronic posthemorrhagic anemia occurs at children rather seldom, more often it can be observed at adults — it is a basic reason of iron deficiency states. Chronic posthemorrhagic anemia in children can be caused by diseases of a digestive tract (polyposes of guts, a peptic ulcer of a stomach and duodenum, ulcer colitis, intestinal parasites, a gullet varicosity, etc.), and also hemorrhagic diathesis (idiopathic trombotsitopsnichesky purpura, hereditary trombotsitopatiya with frequent nasal bleedings, and in girls in the pubertal period — uterine, angiomatous, etc.).
This anemia is characterized by slow rate of development. It should be noted that children rather easily transfer chronic blood losses. The child's organism thanks to compensatory mechanisms adapts to chronic blood losses easier, than to acute in spite of the fact that the total quantity of the lost blood can be considerable big. Researches of cellular kinetics showed that at chronic posthemorrhagic anemia proliferative activity of erythron and an effective erythrocytopoiesis are reduced (S. V. Kanayev, 1969; S. I. Ryabova, 1971, 1973; G. D. Shostka, 1974). As a result of chronic blood losses the depot of iron is constantly exhausted and the sideropenia develops.
The clinical picture depends on severity of anemia. In mild cases anemia a long time can remain unnoticed. Many children feel well at the level of hemoglobin of 90 — 100 g/l. At heavy degree of anemia there are the general weakness, dizziness, a sonitus, physical and mental activity decreases, appetite worsens. Skin is pale, with a wax-like shade or porcelain and pale, mucous membranes of lips, conjunctivas anemic, scleras bluish. The person becomes bloated, on the lower extremities — pastosity, sometimes hypostases. Borders of heart are displaced to the left, over a top and the basis of heart systolic noise of anemic character, tachycardia, on jugular veins — "nun's murmur" is listened, arterial pressure decreases.
Much more often than at acute blood loss, changes of a muscle of heart are expressed. On an ECG — amplitude of teeth P and, signs of disturbance of food of a myocardium is reduced. At the long course of process some increase in a liver and disturbance of its functions is noted.
In peripheral blood — hypochromia anemia, a color indicator within 0,5 — 0,6, sometimes below. The microcythemia, an anisocytosis, a poikilocytosis are observed. Iron level in blood serum is reduced against the increased iron-binding ability of serum. The quantity of leukocytes is normal, but there is a leukopenia, sometimes define shift of a neutrophylic row to the left, a relative lymphocytosis. Treatment first of all is directed to elimination of a bleeding point and recovery of balance of iron. Appoint iron preparations, vitamins, the good nutrition enriched with proteins, the fruit, vegetables and other products containing iron in enough (see. Iron deficiency anemias). At heavy anemia, life-threatening the child, it is possible to resort to a transfusion of erythrocytes, a packed red cells or whole blood.
