Hermansky-Pudlak syndrome in pregnancy: two case studies

Area of Science:

• Genetics and Human Health
• Reproductive Medicine
• Hematology

Background:

• Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disorder characterized by oculocutaneous albinism and a bleeding tendency due to platelet dysfunction.
• Previous literature suggested a high risk of postpartum hemorrhage in HPS patients, impacting obstetric management.
• The prevalence of HPS is notable in specific populations, such as parts of Puerto Rico.

Observation:

• This report details two successful pregnancies in women diagnosed with Hermansky-Pudlak syndrome.
• Both patients experienced favorable outcomes throughout their pregnancies and postpartum periods.
• No significant postpartum hemorrhage complications were observed in these cases.

Findings:

• Successful pregnancy outcomes are achievable in Hermansky-Pudlak syndrome patients.
• The anticipated risk of postpartum hemorrhage may be manageable or less frequent than previously reported.
• Platelet aggregation studies are crucial for diagnosing and managing HPS.

Implications:

• These findings suggest that pregnancy in HPS patients can be managed successfully with appropriate monitoring.
• The results may prompt a re-evaluation of obstetric risk assessment for HPS patients.
• Screening for HPS using platelet aggregation studies should be considered in at-risk individuals and populations.
