Summary
Pregnancy with paroxysmal nocturnal haemoglobinuria (PNH) presents risks, including a 6% mortality rate and 30% spontaneous abortion risk. Careful monitoring during pregnancy and postpartum is crucial for patient and infant outcomes.
Area of Science:
- Hematology
- Obstetrics
- Reproductive Medicine
Background:
- Paroxysmal nocturnal haemoglobinuria (PNH) is a rare, acquired hemolytic anemia.
- PNH is characterized by complement-mediated intravascular hemolysis.
- Pregnancy in women with PNH is uncommon and poses significant risks.
Observation:
- Three cases of PNH in pregnancy were analyzed in women aged 29, 31, and 35.
- One patient experienced two spontaneous abortions and subsequently died by suicide.
- Two pregnancies resulted in uncomplicated deliveries, though one mother had postpartum abdominal crises.
Findings:
- PNH in pregnancy is associated with a 6% risk of lethal complications.
- Approximately 30% of PNH pregnancies end in spontaneous abortion or stillbirth.
- All liveborn infants in this series were healthy and born at term.
Implications:
- Close surveillance of PNH patients throughout pregnancy and the postpartum period is essential.
- Management strategies should focus on mitigating thrombotic and hemolytic risks.
- Further research is needed to optimize care for pregnant women with PNH.
