Abstract
MARTINEZ PEREZ, Lianet; NUNEZ GARCIA, Aray; GARCIA GARCIA, Alina and LOPEZ GONZALEZ-MOLLEDA, Julio César. Different forms of presentation of megaloblastic anemia in the infant. Rev Cubana Pediatr [online]. 2022, vol.94, n.3 Epub July 20, 2022. ISSN 1561-3119.
Introduction:
Megaloblastic anemia is a maturing disorder of the erythroid and myeloid precursors caused by deficiency of vitamin B12, folic acid, or both. It is uncommon in childhood and its prevalence is unknown because it is a rare disease.
Objective:
To describe different forms of presentation of megaloblastic anemia in infants.
Presentation of cases:
Two cases of infants are presented, in case 1 the mother had a precarious diet during pregnancy and lactation, and prolonged exclusive breastfeeding more than 6 months. The patient began to lose the skills gained in psychomotor development and presented severe neurological disorders, so it was considered that it was a progressive disease of the central nervous system. In case 2, in which exclusive breastfeeding was prolonged, thrombocytopenia appeared, so a malignant hematological disease was suspected.
Results:
In both cases, after performing various tests to rule out neurological diseases (case 1) and hematological diseases (case 2), megaloblastic anemia was diagnosed due to vitamin B12 deficiency due to a decrease in intake and a borderline reserve in the breastfeeding mother. In both cases the symptoms disappeared with vitamin replacement therapy.
Conclusions:
In the infant, megaloblastic anemia can occur in different clinical ways despite having the same cause, a deficit in intake and a low reserve of the mother during pregnancy and lactation.
