A Clinical Trial of Oral Versus IV Iron in Patients With Chronic Kidney Disease
Stopped early · Phase 4
Conditions studied: Chronic Kidney Disease, Iron-deficiency Anemia
In brief
The long-term goal is to assess the fall in kidney function measured by glomerular filtration rate (GFR) when patients with chronic kidney disease (CKD) are exposed to intravenous iron (IVIR). We hypothesize that in subjects with mild to moderate CKD, infusion of intravenous iron (IVIR), will generate oxidative stress and cause an inflammatory response that will be associated with a more rapid decline in glomerular filtration rate (GFR) compared to oral iron.

Who can join
Age: 18 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Age greater than 18 years
- Calculated GFR by MDRD formula < or = 60ml/min/1.73m2. We will use the MDRD formula that incorporates serum creatinine, age, race and sex, but not albumin, and blood urea nitrogen.
- Presence of anemia and iron deficiency. Anemia will be defined as blood hemoglobin concentration <12g/dL and iron deficiency will be defined using National Kidney Foundation/Kidney Disease Outcome Quality Initiative (NFK-K/DOQI) Guidelines as serum ferritin concentration of <100ng/mL or serum transferrin saturation of <25%.
You may not qualify if…
- Pregnant or breastfeeding women or women who are planning to become pregnant or those not using a reliable form of contraception (oral contraceptives, condoms, and diaphragms will be considered reliable).
- Known hypersensitivity to iron sucrose (Venofer), iothalamate meglumine (Conray 60, Mallinckrodt) or iodine.
- Anemia that requires RBD transfusion (Hgb <8g/dL) or may potentially need transfusion (active gastrointestinal bleeding). It would be unsafe to withdraw 150 mL blood over the study in such anemic patients.
- Presence of acute renal failure defined as an increase in the baseline serum creatinine concentration of 0.5 mg/dl over 48 hours. This would produce oxidative stress by itself, may give unreliable rate of decline in renal function and may confound results.
- History of IVIR use within 1 month of the study (may confound results of the study if the baseline oxidative stress is increased).
- Evidence of iron overload (serum ferritin >800ng/nl or transferrin saturation >50%)
- Anemia not caused by iron deficiency eg. sickle cell anemia.
- Surgery or systemic or urinary tract infection within 1 month.
- Organ transplant recipient or therapy with immunosuppressive agents. Nasal or inhaled corticosteroids will be permitted.
