Abstract

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 hypoantigenic nature and altered metabolic profile, has all the potential of a real and safe alternative to adult blood transfusion. Our experience of 74 units (50 mL - 146 mL mean, 86 mL ± 7.6 mL SD, median 80 ml, mean packed cell volume 48 ± 4.1 SD, mean percent hemoglobin concentration 16.2 g/dL ± 1.8 g/dL of placental umbilical cord whole blood collection (from 1 April 1999) after lower uterine cesarean section (LUCS) from consenting mothers and transfusion of the same to 16 informed, consenting patients with percent plasma hemoglobin 8 g/dl or less, is presented here. After collection the blood was immediately preserved in the refrigerator and transfused within 72 hours of collection. Fifteen males and one female, aged 12-72 yrs (mean 48.4 yrs) partic­ipated: five cases were pausibacillary type (PB) and 11 cases were multibacillary type (MB). The clinical spectrum of the cases varied widely from the tuberculoid to the lepromatous type and one patient presented with gangrene of the leg preceding an auto amputation which was infested with maggots. Each case was approved by the institutional ethical committee and received two to eight units of freshly collected placental umbilical cord blood in one transfusion without encountering any clinical, immunological or non-immunological reaction. Seven days after completion of the placental umbilical cord blood transfusion, the peripheral blood hematopoietic stem cell (CD34) estimation revealed a rise from the pretransfusion base level (0.09%), varying from 3.6% to 16.2%, in 75% of the cases, without provoking any clinical graft vs host reaction in any of the leprosy victims. This value returned to normal within three months in most cases.
