Abstract
The Bombay blood group is a rare blood type with an incidence of around one in a million. There is no known reported case of an obstetric patient with the Bombay blood group from Nepal. People with this rare blood group can receive blood only from those with the same blood type. We report an elderly gravida with the Bombay blood group who had a pregnancy complicated by diabetes, placenta previa, and transverse lie (back up) following an in vitro fertilization. Placenta previa posed a greater risk of hemorrhage and hence the need for transfusion. The main challenge was arranging blood for transfusion, and as the Bombay blood group was unavailable, she was managed with autologous blood transfusion which was performed for the first time in a pregnant lady in our institute. She underwent Cesarean section for placenta previa with transverse lie, and both mother and baby were sent home in good health.
Highlights
The Bombay blood group known as h/h or Oh is an extremely rare blood type, first reported in Bombay by Dr Bhende et al in 1952 [1]
It occurs in about 1/10,000 individuals in India and in about 1/1,000,000 in Europe [2]. It is characterized by the absence of A, B, and H antigens on red blood cells (RBCs) and presence of anti-A, anti-B, and anti-H in serum
We report a case of a 41-year-old G3P2L1 lady of Indian descent, married to a Nepali with the rare Bombay blood group
Summary
The Bombay blood group known as h/h or Oh is an extremely rare blood type, first reported in Bombay by Dr Bhende et al in 1952 [1] It occurs in about 1/10,000 individuals in India and in about 1/1,000,000 in Europe [2]. It is characterized by the absence of A, B, and H antigens on red blood cells (RBCs) and presence of anti-A, anti-B, and anti-H in serum. As these individuals have antibodies in plasma reacting with all ABO phenotypes, they can receive blood only of the Bombay blood type [1, 2]. Owing to the rarity of the Bombay blood group, this case report is aimed at adding to the very scarce literature apart from discussing the challenges in this case
