Riboflavin deficiency and preeclampsia.

Area of Science:

• Obstetrics and Gynecology
• Nutritional Science
• Biochemistry

Background:

• Preeclampsia is a major cause of maternal and fetal morbidity.
• Identifying predisposing factors is crucial for early intervention.
• Riboflavin (vitamin B2) plays a vital role in cellular metabolism.

Purpose of the Study:

• To investigate the association between riboflavin deficiency and preeclampsia risk.
• To assess riboflavin status in a high-risk pregnant population in Zimbabwe.

Main Methods:

• Prospective observational study of 154 high-risk pregnant women in Bulawayo, Zimbabwe.
• Riboflavin status assessed using the erythrocyte glutathione reductase activation coefficient test.
• Deficiency defined as an activation coefficient of 1.4 or greater.

Main Results:

• Riboflavin deficiency was prevalent (33.8%) and increased in late pregnancy.
• Riboflavin-deficient women had a significantly higher incidence of preeclampsia (28.8% vs. 7.8%).
• Lower intracellular flavin adenine dinucleotide levels were observed in preeclamptic pregnancies.

Conclusions:

• Riboflavin deficiency is a potential risk factor for preeclampsia.
• Reduced flavin adenine dinucleotide and flavin adenine mononucleotide may contribute to preeclampsia pathophysiology.
• This highlights the importance of adequate riboflavin status in pregnancy.
