Diagnostic factors for recurrent pregnancy loss: an expanded workup

Area of Science:

• Reproductive Medicine
• Genetics
• Immunology

Background:

• Recurrent pregnancy loss (RPL) affects a significant number of women, yet comprehensive risk factor identification remains limited.
• Understanding the multifactorial nature of RPL is crucial for developing effective diagnostic and therapeutic strategies.

Purpose of the Study:

• To investigate the involvement and relative importance of numerous diagnostic factors in women experiencing recurrent pregnancy loss.
• To establish a patient-based diagnostic approach for recurrent pregnancy loss.

Main Methods:

• A patient-based diagnostic workup was conducted on 843 women with RPL.
• A comprehensive analysis included 44 diagnostic factors across 7 major categories.
• Statistical analysis was performed to correlate abnormalities with the number of pregnancy losses.

Main Results:

• High prevalence rates of abnormalities were observed, including thrombophilias (62%), autoimmune abnormalities (39.2%), and clinical factors (87.78%).
• Most women (78.17%) presented with multiple abnormalities, and an increasing number of abnormalities correlated with more pregnancy losses.
• Specific factors like cervical isthmic incompetence and certain antibodies/deficiencies were strongly associated with higher pregnancy loss rates.

Conclusions:

• A patient-based diagnostic approach is clinically valuable for managing recurrent pregnancy loss.
• The findings provide a foundation for future research into the complex etiology of RPL.
