title: Placental umbilical cord whole blood transfusion to combat anemia in the background of advanced rheumatoid arthritis and emaciation and its potential role as immunoadjuvant therapy.
abstract: Rheumatoid arthritis is the commonest form of inflammatory arthritis and affects about 1-3% of the population in the West and even more in the developing world due to the compounded factors of late detection and inadequate treatment in the overall background of poverty, deprivation, and improper macro and micronutrients in the diet in a sizeable segment of the population. Nearly 90% of patients with aggressive disease will become clinically disabled within 20 years. Furthermore, in patients with severe disease or extra-articular symptoms, mortality is equal to that for patients with triple artery coronary artery disease or Stage IV Hodgkin's lymphoma. Anemia is a very common comorbidity of rheumatoid arthritis. Anemia in rheumatoid arthritis is caused by various factors, for instance, cytokine impact of the advanced arthritic process on the host, or lack of proper nutrition and essential micronutrients in the diet, or coexistent helminthiasis, and/or impact of antiarthritic drugs on the host system, i.e., high steroid induced gastritis or ulcerations in gastric mucosa or subclinical or clinical hepatitis due to methotrexate or salazopyrin effects on bone marrow, only to name a few. Other pre-existing or compounding gastrointestinal problems, which alter the available iron stores or cause bone marrow dysfunction, may also help in adding to an anemic condition. If the anemia is 8 g/dl or less, blood transfusion or erythropoietin injection with adequate hematinic reserve is effective in normal situations, but is not that effective in anemia with a chronic disease background like rheumatoid arthritis. Cord blood, because of its rich mix of fetal and adult hemoglobin, high platelet and white blood cell (WBC) counts, and a plasma filled with cytokine and growth factors, as well as its hypo antigenic nature and altered metabolic profile, has all the potential of a real and safe alternative to adult blood transfusion. Seventy-eight units (42 ml -136 ml mean 80.6 ml +/- 3.6 ml SD, median 82.4 ml, mean packed cell volume 48.2 +/- 2.1 SD, mean percent hemoglobin concentration 16.4 g/dl +/- 1.5 g/dl SD) of placental umbilical cord whole blood was transfused (from 1 April 1999 to April 2005) after lower uterine cesarean section (LUCS) from consenting mothers to 28 informed consenting patients with advanced rheumatoid arthritis who had plasma hemoglobin of 8 g/dl or less. After collection, the blood was immediately transfused following the standard adult blood transfusion protocol. Each case was passed through the institutional ethical committee. The patients received two to six units of freshly collected placental umbilical cord blood without encountering any clinical, immunological or non-immunological reactions. Three days after completion of the transfusion of placental umbilical cord blood, the peripheral blood hematopoietic stem cell (CD34) estimation revealed a rise from the pretransfusion base level (.09%), varying from 2.03 to 23%, which returned to base level in most of the cases at the three-month CD34 re-estimation, without provoking any clinical graft vs host reaction in any of the patients.
