Further study details as provided by Duzce University:

Primary Outcome Measures:

Significant improvement in Hgb and RBC [ Time Frame: 3 months ]

Secondary Outcome Measures:

Significant improvement in serum iron, ferritin, TIBC and possibly in serum TSH and free T4 levels. [ Time Frame: 3 months ]

Study Start Date:	June 2007
Study Completion Date:	September 2007

Arms	Assigned Interventions
1: Active Comparator Oral iron treatment only- for iron deficiency anemia and subclinical hypothyroidism coexisting patients	Drug: Ferrous sulfate tablets 325 mg, po, TID
2: Active Comparator Oral iron plus levothyroine treatment- for iron deficiency anemia and subclinical hypothyroidism coexisting patients	Drug: Ferrous sulfate plus levothyroxine Combination of ferrous sulfate tablet 325mg plus levothyroxine tablet 25 micrograms, po, TID

Detailed Description:

51 Patients presented to our university outpatient internal medicine clinic who are found to have iron deficiency anemia coexisting with subclinical hypothyroidism have been included in this study. Patients were randomly assigned to oral iron or oral iron plus levothyroxin therapy. The physician and the patients did not know who received oral iron only or oral iron plus levthyroine treatment. Hemotologic parameters as well as serum iron, ferritin and iron binding capacity were be measured at the beginning and 3 months after treatment in both groups.
