Umbilical cord blood transfusions in low-income countries

Knowledge of umbilical cord blood banking among obstetricians and mothers in Anand and Kheda District, India

Background:

To assess the knowledge of obstetricians and expectant mothers towards UCB banking and their awareness regarding pros and cons of the process.

Methods:

Questionnaires from a previously published study were modified contextually and translated into vernacular language (Gujarati). The questionnaires were distributed among 200 obstetricians, of which 100 responded and 100 mothers were in Anand and Kheda districts of India. Informed consent was taken for both.

Results:

Mean (SD) age of obstetricians was 47.5 years (11.14) with mean (SD) work experience of 19.72 years (9.94). Almost all were aware of collection procedure for UCB and felt that UCB banking is useful. Thirty obstetricians thought that stored blood can be used in conditions of Autism, Duchenne Muscular Dystrophy and all genetic conditions. Sixty-three were aware of the procedure technique. Majority felt that the process was feasible and would do it for their own child. All the 100 mothers approached consented for the study with average age (SD) of 26.88 (4.17). Many were not aware of such a procedure and were not certain about the usefulness of the procedure. Seventy-six did not know the conditions in which the stored blood can be used. Only 4 mothers/family members had opted for UCB banking, whereas 27 expressed their willingness to recommend UCB to another mother. Five Muslim women wanted UCB but could not pursue it due to religious norms.

Conclusion:

The level of understanding among obstetricians was not commensurate with the amount of faith with which they promoted UCB banking.

Umbilical cord blood as a source for red-blood-cell transfusion in neonatology: a systematic review

The prevention and treatment of anaemia in newborn patients made tremendous progress in the last decades. However, red-blood-cell (RBC) transfusions remain unavoidable in many neonates candidate to surgery and especially in preterm infants. In particular, anaemia occurring in neonates born at extremely low gestational age is actually severe and frequently requires transfusions. Several approaches have been explored to prevent or even to reduce the threshold and the frequency of RBC transfusions. Among these, umbilical cord blood (UCB) collection and processing to obtain RBC components for autologous or allogeneic transfusion have been extensively investigated. In this systematic review, we revised the literature concerning the use of UCB for either autologous or allogeneic transfusion purposes and we illustrated the rationale for a transfusion therapy tailored to extremely preterm neonates, based on RBC concentrates from allogeneic UCB donations.

Placenta and Placental Derivatives in Regenerative Therapies: Experimental Studies, History, and Prospects

Placental structures, capable to persist in a genetically foreign organism, are a natural model of allogeneic engraftment carrying a number of distinctive properties. In this review, the main features of the placenta and its derivatives such as structure, cellular composition, immunological and endocrine aspects, and the ability to invasion and deportation are discussed. These features are considered from a perspective that determines the placental material as a unique source for regenerative cell therapies and a lesson for immunological tolerance. A historical overview of clinical applications of placental extracts, cells, and tissue components is described. Empirically accumulated data are summarized and compared with modern research. Furthermore, we define scopes and outlooks of application of placental cells and tissues in the rapidly progressing field of regenerative medicine.
