Anemia is the most common systemic complication of inflammatory bowel disease (IBD); so common that it is almost invariably not investigated and rarely treated. Several misconceptions are the reason for these clinical errors, and our goal will be to review them. The most common misconceptions are: anemia is uncommon in IBD; iron deficiency is also uncommon; just by treating the intestinal disease, anemia will be corrected; iron deficiency is the only cause for anemia in IBD; ferritin is an accurate parameter for the diagnosis of iron deficiency in IBD; the impact of anemia on the quality of life of IBD patients is limited; iron supplementation is rarely needed in IBD; high-dose oral iron solves the problem of iron
malabsorption
in IBD; intravenous (IV) iron is dangerous and of no proven benefit in IBD; IV iron is useful only for severe anemia; and erythropoietin has no role in the treatment of IBD anemia. These misconceptions are not evidence-based. On the contrary, there is enough evidence to support the following statements: (a) anemia is very common in IBD, (b) anemia should be investigated with care because many factors can be responsible, (c) treatment of anemia results in clear improvement in the objective parameters of well-being, especially in the quality of life, (d) IV iron is safe and effective in the treatment of iron deficiency anemia in IBD patients, and (e) erythropoietin is useful in a subset of patients with
refractory anemia
. Anemia diagnosis and treatment must not be neglected in IBD patients, and several misconceptions should be promptly abandoned.

Celiac disease is an immune-mediated disorder induced by the intake of gluten proteins involving primarily the gastrointestinal tract. Myelodysplastic syndromes are clonal hematologic disorders, expanded from myeloid stem cells of uncertain pathogenesis. Anaemia is a common finding in patients with celiac disease. Frequently it is secondary to
malabsorption
of iron, folic acid or vitamin B12 and usually disappears completely with a strict adherence to a gluten-free diet and supplement of deficient factors. To the best of our knowledge, in medical literature only two cases of myelodysplastic syndrome associated with celiac disease have been described. Here we describe the case of a patient affected by adult celiac disease who went into remission following a gluten free diet. Later a macrocytic anaemia without vitamin B12 or folate deficiency appeared. Hematologic tests showed findings consistent with
refractory anemia
with ring sideroblasts. The association of celiac disease with myelodysplastic syndromes seems not to be casual. It raises the hypothesis of a primitive immunological disorder in both diseases.

The paper considers the causes of iron- and cyanobalamin-deficiency anemias caused by gastrointestinal tract (GT) diseases, among which
malabsorption
along with loss of these nutrients through the GT is of great importance. The paper reflects the current views of the pathogenesis of deficiency anemias that develop in gluten-sensitive celiac disease and atrophic gastritis. Among the atrophic gastritides, there are two forms caused by autoimmune processes and long-term Helicobacter pylori persistence, whose treatment is an effective measure in
refractory anemia
. The paper gives the provisions of the Russian Gastroenterology Association Guidelines (2012) for the management of H. pylori infection, which are based on Maastricht IV consensus (2010).
