B12-deficiency anemia combined with active cytomegalovirus infection in a one-year-old child

The article presents a clinical case of B12-deficiency anemia in combination with active cytomegalovirus infection in a one-year-old child. This type of anemia is extremely rare in childhood, under certain circumstances, including the enthusiasm for restrictive diets among young patients’ mothers. In the described case, severe megaloblastic macrocytic anemia was combined with generalized cytomegalovirus infection, which aggravated the course and prognosis of the disease. These pathologies led to damage of the central nervous system with a tempo neurological deficit, as well as the development of protein-energy insufficiency. Complex therapy included hemotransfusion of erythrocyte mass, injections of anticytomegalovirus immunoglobulin and cyanocobalamin. The general condition of the child improved, recovery of previously lost skills and significant positive laboratory dynamics were noted after the therapy.
