Neonatal death in babies with rhesus isoimmunization
The Quarterly Journal of Medicine
|April 1, 1979
Summary
Rhesus isoimmunization caused 4.5% mortality in newborn hemolytic disease. Intensive care and a specialized center significantly reduced deaths, improving outcomes for affected infants.
Area of Science:
- Neonatal Medicine
- Pediatric Hematology
- Immunology
Background:
- Haemolytic disease of the newborn due to Rhesus isoimmunization is a significant cause of neonatal mortality.
- Severe anemia and hydrops fetalis present critical challenges in management.
- Complications include cerebral/pulmonary hemorrhage, coagulation failure, and hyaline membrane disease.
Purpose of the Study:
- To analyze the outcomes of infants born with haemolytic disease of the newborn due to Rhesus isoimmunization over a 27-year period.
- To identify risk factors for mortality and severe complications.
- To evaluate the impact of medical advancements and specialized care on neonatal mortality rates.
Main Methods:
- Retrospective analysis of 4315 live births weighing over 1 kg between 1951-1977.
- Review of clinical data including cord hemoglobin, presence of hydrops, gestational age, and treatment interventions.
- Comparison of mortality rates with national averages and assessment of the impact of a dedicated referral center.
Main Results:
- Overall mortality was 4.5% (197 deaths).
- Severe anemia and hydrops fetalis were associated with high mortality.
- Introduction of closed chest cardiac massage reduced risks during exchange transfusion, though circulatory collapse remained a concern (1.5%).
- Kernicterus posed a substantial risk in preterm infants (<36 weeks) with respiratory issues when bilirubin levels exceeded 270 mumol/l.
- A single referral center reduced neonatal mortality by half compared to the national average.
Conclusions:
- Rhesus isoimmunization remains a critical condition requiring intensive neonatal care.
- Advancements in resuscitation and transfusion techniques have improved survival.
- Centralized care significantly reduces neonatal mortality for Rhesus isoimmunization, highlighting the importance of specialized treatment centers.

01:22Development 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.

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
