Resumen
FLORES-MONTES, Olivia Alejandra; ESCOBAR-ORDUNO, Martha Cecilia; LOZANO-GARCIDUENAS, Mónica y VALLE-LEAL, Jaime Guadalupe. Evans syndrome in infants. Bol. Med. Hosp. Infant. Mex. [online]. 2017, vol.74, n.2, pp.141-146. ISSN 1665-1146. https://doi.org/10.1016/j.bmhimx.2017.01.004.
Background:
Evans syndrome is characterized by the reduction of at least two blood cell lineages in the absence of other diagnoses; it was previously described as the simultaneous or sequential development of autoimmune hemolytic anemia and immune thrombocytopenia with unknown etiology. An incidence of 37% and mortality rate of 10% were reported for Evans syndrome.
Clinical cases:
We report the clinical presentation and evolution of Evans syndrome in two infants who were initially diagnosed with immune thrombocytopenia. The clinical diagnosis was supported on complementary studies, where hematological disorders were corroborated. Both cases received treatment with steroids and intravenous immunoglobulin.
Conclusions:
For the management of children with thrombocytopenia, the pediatrician must analyze for other cell lineage disorders. In the cases that we report here, we found the presence of autoimmune hemolytic anemia and monocytosis. Therefore, infectious and immunological studies must be included. The first-line treatment of choice are steroids, and intravenous immunoglobulin can be considered if severe immune thrombocytopenia is associated, as observed in these cases.
