[Human fetal liver in hematogenic infection (a morphometric study)]

Area of Science:

• Pathology
• Fetal Development
• Hepatology

Background:

• Human fetal liver development is complex and vulnerable to intrauterine insults.
• Intrauterine infections and hypoxia can significantly impact fetal organogenesis.
• Understanding liver changes in compromised fetuses is crucial for perinatal care.

Purpose of the Study:

• To investigate the morphometric changes in human fetal livers (26-27 weeks gestation) affected by intrauterine hypoxia and infection.
• To compare pathological liver findings in affected fetuses with control groups.
• To identify the relationship between infection, hypoxia, and liver tissue alterations.

Main Methods:

• Morphometric analysis of 40 human fetuses (26-27 weeks gestation).
• Histopathological examination of liver parenchyma.
• Assessment of intrauterine hypoxia and infection signs.
• Comparative analysis between affected and control fetuses.

Main Results:

• Fetuses with intrauterine infection showed significant destructive changes in liver parenchyma.
• Increased extramedullary hematopoiesis (blood formation) was observed in affected livers.
• Intrauterine infection was associated with portal tract sclerosis and reduced Kupffer cell numbers.
• Secondary hypoxia and intoxication likely contribute to observed liver pathology.

Conclusions:

• Intrauterine hematogenic infection leads to severe destructive liver changes and altered hematopoiesis.
• Destructive liver changes, intoxication, and hypoxia create conditions for generalized infection and portal tract sclerosis.
• A decrease in Kupffer cells may impair the fetal liver's immune response, exacerbating infection.
