Hematologic and metabolic abnormalities in a patient with anorexia nervosa.
Anorexia nervosa is a common problem in young adults that may present with a variety of metabolic and hematologic abnormalities, as well as weight loss and psychological disturbances. We present a young man with a long history of anorexia nervosa who developed pancytopenia associated with decreased bone marrow cellularity and abnormal architecture and marrow infiltration with an amorphous, gelatinous substance characteristic of anorexia nervosa. The patient also developed osteopenia with evidence of excessive calcium excretion. The pancytopenia and marrow function reverted to normal with therapeutic and dietary intervention. The effects of eating disorders can result in serious consequences with respect to an individual's health and well-being. A host of hematologic abnormalities that are associated with anorexia nervosa have the potential of increasing the risk of infection and bleeding. Additionally, because of the insidious development of anemia in some patients, decreased performance status and chronic fatigue can pose significant compromises in one's daily activities and work effort. Anorexia nervosa is a chronic illness that is distinctly more common in females than in males (ratio of 10 to 1), but can affect males in an equally debilitating manner, requiring multiple modalities of therapeutic intervention and consultation. We present the case of a male referred to the hematology department because of pancytopenia, chronic fatigue, and back pain. A diagnosis of anorexia nervosa had been made 10 years prior at the age of 18 years.
