Recurrent Miscarriage in SubSaharan Africa Exploring Causes, Challenges, and Future Solutions

Introduction

Understanding the Scope of Recurrent Miscarriage

  • Defined as the loss of two or more consecutive pregnancies, recurrent miscarriage affects around 5% of couples globally.
  • In Africa, the definition is adapted to local resource constraints, considering pregnancy losses of fetuses over 500g or before 24 weeks.
  • Studies indicate the condition remains poorly managed in Sub-Saharan Africa, often misdiagnosed or undetected.

Genetic and Immunologic Etiologies

  • Genetic factors, such as balanced chromosomal translocations, are rarely diagnosed due to limited access to cytogenetic testing.
  • In a rare reported case from Rwanda, a balanced translocation [46.XX, t(13p,21p)] was found in a woman with four consecutive miscarriages.

Anatomical and Endocrine Factors

  • Uterine anomalies like bicornuate or septate uterus contribute significantly to infertility and miscarriage.
  • Endocrine issues including diabetes mellitus and thyroid dysfunction were also highlighted. Poorly managed diabetes (HbA1C >8%) correlates with higher risk of early miscarriage.

Infectious Agents

  • Pathogens such as Listeria monocytogenes, Rubella, Cytomegalovirus, and Herpes simplex are suspected contributors, though their role in recurrent loss is still debated.

Unexplained Losses and Resource Gaps

  • Up to 70% of RM cases in the region are classified as unexplained, likely due to limitations in diagnostic infrastructure.
  • Many patients lack access to immunogenetic testing or chromosomal screening.

Solutions and Future Directions

  • Early chromosomal testing and immunogenetic profiling can help personalize care.
  • Cervical cerclage has shown significant success, with up to 89.4% child take-home rate in elective procedures.
  • More localized studies are necessary to establish region-specific protocols.
  • Genetic counseling and lifestyle modifications such as folic acid supplementation are simple, impactful interventions.
