Paroxysmal nocturnal hemoglobinuria (PNH) during pregnancy poses significant risks, including severe anemia, hemolytic crises, and Budd-Chiari syndrome. Early detection and management are crucial for maternal and fetal well-being.
Area of Science:
- Hematology
- Obstetrics & Gynecology
- Thrombosis
Background:
- Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired blood disorder.
- Pregnancy in women with PNH presents unique and serious challenges.
Observation:
- A case study of a patient with PNH during two pregnancies.
- The first pregnancy resulted in preterm delivery; the second involved severe anemia, hemolytic crisis, and Budd-Chiari syndrome.
Findings:
- PNH is associated with high maternal mortality (5.8%), primarily due to Budd-Chiari syndrome (liver vein thrombosis).
- Pregnancy with PNH carries high rates of fetal wastage (30%) and prematurity (16%).
Implications:
- Highlights the critical need for specialized management of PNH patients during pregnancy.
- Recommends anticoagulation, transfusions, and vigilant screening for Budd-Chiari syndrome and infections.
- Emphasizes the importance of multidisciplinary care for improving outcomes in PNH pregnancies.

Blood Transfusion and Agglutination
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
