The most common indications for intravenous therapy include GI effects, worsening symptoms of inflammatory bowel disease, unresolved bleeding, renal failure–induced anemia treated with erythropoietin, and insufficient absorption in patients with celiac disease.32, Parenteral treatment options are outlined in Table 3.2,16 Serious adverse effects have occurred in up to 0.7 percent of patients receiving iron dextran, with 31 recorded fatalities reported between 1976 and 1996.32,33 Iron sucrose and sodium ferric gluconate (Ferrlecit) have greater bio-availability and a lower incidence of life-threatening anaphylaxis compared with iron dextran.2 Approximately 35 percent of patients receiving iron sucrose have mild adverse effects (e.g., headache, nausea, diarrhea).7 One small study cited similar adverse effect profiles between intravenous iron dextran and sodium ferric gluconate, with only one serious adverse effect reported in the iron dextran group.34 If this finding is duplicated in larger studies, it could support the use of iron dextran over sodium ferric gluconate, because the total dose can be given in one sitting.

European consensus on the diagnosis and management of iron deficiency and anaemia in inflammatory bowel diseases. Values consistent with iron deficiency include a low serum iron level, low transferrin saturation, and a high total iron-binding capacity.2, Soluble transferrin receptor and erythrocyte protoporphyrin testing, or bone marrow biopsy can be considered if the diagnosis remains unclear.2 The soluble transferrin receptor level is an indirect measure of erythropoiesis and is increased in patients with iron deficiency anemia.8 Another benefit of this test is that the soluble transferrin receptor level is unaffected by inflammatory states and can help identify concomitant iron deficiency anemia in patients with anemia of chronic disease.12 Erythrocyte protoporphyrin is a heme precursor and accumulates in the absence of adequate iron stores.11 If other tests are indeterminate and suspicion for iron deficiency anemia persists, the absence of stainable iron in a bone marrow biopsy is considered the diagnostic standard.2, Asymptomatic men and postmenopausal women should not be screened for iron deficiency anemia. Intravenous iron in a primary-care clinic. These effects may be reduced when iron is taken with meals, but absorption may decrease by 40 percent.1 Medications such as proton pump inhibitors and factors that induce gastric acid hyposecretion (e.g., chronic atrophic gastritis, recent gastrectomy or vagotomy) are associated with reduced absorption of dietary iron and iron tablets.31, Parenteral therapy may be used in patients who cannot tolerate or absorb oral preparations, such as those who have undergone gastrectomy, gastrojejunostomy, bariatric surgery, or other small bowel surgeries.
