Summary
Histologically confirmed chorioamnionitis, an infection of the placenta, significantly increases the risk of neonatal adnatal infection and mortality. Early detection and management are crucial for improving infant outcomes.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Medicine
- Pathology
Background:
- Chorioamnionitis is a placental infection that can affect neonatal health.
- The association between chorioamnionitis and neonatal infection requires further investigation.
Purpose of the Study:
- To investigate the relationship between histologically confirmed chorioamnionitis and the development of neonatal adnatal infection.
- To assess the impact of chorioamnionitis on neonatal mortality rates.
Main Methods:
- Retrospective analysis of 252 placentas from pathological deliveries between January 1, 1988, and December 31, 1989.
- Histological examination of placentas to identify inflammatory changes indicative of chorioamnionitis.
- Comparison of adnatal infection rates and mortality between neonates with and without chorioamnionitis.
Main Results:
- Chorioamnionitis was detected in 28.6% of examined placentas.
- Neonates with chorioamnionitis had a significantly higher incidence of adnatal infection (20.8%) compared to those without (4.4%).
- The mortality rate from adnatal infections was significantly higher in neonates with chorioamnionitis (4.16%) than in those without.
Conclusions:
- Histologically confirmed chorioamnionitis is strongly associated with an increased risk of neonatal adnatal infection.
- Chorioamnionitis is linked to a significantly higher mortality rate in neonates due to adnatal infections.
- These findings underscore the importance of identifying and managing chorioamnionitis to improve neonatal outcomes.

Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
Bacterial Phylum Chlamydiae
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic of...
Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
