Brief Summary
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by chronic inflammation limited to the mucosal layer of the colon. Anemia is a consistent clinical feature of IBD. It is encountered in one third of IBD patients, and is the most common extraintestinal complication of this disease. Anemia has a significant impact on the quality of life of affected patients. Many patients with IBD frequently complain of chronic fatigue commonly caused by anemia and this may be as debilitating to patients as abdominal pain and diarrhea. Anemia in IBD is multifactorial, but is most commonly the result of iron deficiency anemia (IDA) and rarely due to anemia of chronic disease (ACD). Oral iron supplementation has been used traditionally for the treatment of IDA but studies have shown that it may result in disease exacerbation by increasing oxygen free radicals within the lumen of the gut via the Fenton reaction. A recent study done in University Hospitals Birmingham, United Kingdom, has shown that treatment with oral iron results in failure to control anemia in 2 out of 3 IBD patients, which is in part due to the side effects reported by over half of patients. Captafer is a new iron-free oral preparation that contains a special type of oligosaccharides from fish muscle tissue able to make the intestine absorb 3 to 5 times more iron in comparison to the "meat factor". Moreover, Captafer contains other vitamins and supplements that improve anemia.

Outcome Measures
Primary Outcomes (1)
Tolerability to Iron sulfate and Captafer® assessed by the number of patients suffering from treatment related side effects using a Treatment Tolerability Assessment Questionnaire 4 point numerical scale (0,1,2,3).
A 4 point (0,1,2,3) numerical scale will be used to assess the presence and frequency of drug related side effects experienced throughout the study, with scoring done at 4 instances: at baseline prior to initiating the first arm of therapy, at the end of the 6 week treatment period, at baseline after the completion of a 2 week washout period and prior to crossing over, and at the end of the cross over 6 week treatment period. Scores are as follows: 0 = Never, 1 = 2 to 3 times per month, 2 = 2 to 3 times per week, and 3 = daily.
The change of treatment related side effect frequency between baseline (pre-treatment) and end of treatment periods.
Secondary Outcomes (2)
Number of patients responding to therapy by measuring the change in the following laboratory measures Hemoglobin, Hematocrit, Iron, Total Iron Binding Capacity, Ferritin, Transferrin Saturation and c-reactive protein.
The change in hemoglobin, hematocrit, iron, TIBC, ferritin, transferrin saturation and c-reactive protein between baseline (pretreatment), following 6 weeks of first arm of therapy, at baseline post 2 week washout period, and 6 weeks post crossover
Number of patients compliant and adherent to treatment intake assessed by paper logged pill counts conducted at 4 different time points.
End of 6 weeks before 2 weeks washout, and end of 6 weeks after 2 weeks of washout
Study Arms (2)
Initial therapy with Captafer®
EXPERIMENTALThis arm will consist of 10 patients who will begin Captafer® therapy twice daily for 6 weeks, then undergo a 2 week washout period before crossing over to Iron Sulfate therapy twice daily for an additional 6 weeks.
Initial therapy with Iron Sulfate
EXPERIMENTALThis arm will consist of 10 patients who will begin Iron Sulfate therapy twice daily for 6 weeks, then undergo a 2 week washout period before crossing over to Captafer® therapy twice daily for an additional 6 weeks.
Interventions
2 pills daily. Contains * Vitamin C, known for its property to facilitate iron absorption by reducing iron to the reduced ferrous state necessary for uptake; * Vitamin E, an antioxidant, along with vitamin C it protects Fe++; * Folic acid, necessary to prevent megaloblastic anemia and abnormalities in the fetal nervous system, vital during pregnancy; * Zinc and Copper which act in different mitochondrial cytochromes-dependent systems and contribute to the use of iron by the biological systems
195 mg Iron supplement
