  • Title: The hematology of anorexia nervosa.
    Author: Hütter G, Ganepola S, Hofmann WK.
    Journal: Int J Eat Disord; 2009 May; 42(4):293-300. PubMed ID: 19040272.
    Abstract:
    OBJECTIVE: Changes of the peripheral blood cell count in patients with anorexia nervosa (AN) are frequent. Anemia and leukopenia are observed in one-third of these patients. Examination of the bone marrow reveals in almost 50% of the patients with AN signs of bone marrow atrophy and can additionally suffer from a gelatinous bone marrow transformation. METHOD: Published studies and investigations concerning hematological changes in patients with AN were reviewed. RESULTS: Anemia and mild neutropenia are detectable in almost one-third of these patients, whereas thrombocytopenia is rather uncommon. The exact mechanism for these findings is still unclear, but 50% of AN-patients with hematological changes display morphological signs of partial bone marrow atrophy. DISCUSSION: Changes of the peripheral blood cell count in patients with AN is a frequent observation but the peripheral blood cell count cannot predict the severity of bone marrow atrophy. All hematological and morphological alterations disappear completely and rapidly after sufficient refeeding.
