Insights
Early blood exchange transfusion can improve outcomes for infants with malignant pertussis. This intervention rapidly reduced white blood cell counts, leading to clinical improvement and a favorable prognosis in a severe case.
Area of Science:
- Pediatrics
- Hematology
- Infectious Diseases
Background:
- Malignant pertussis is a severe form of whooping cough characterized by extreme leukocytosis and high mortality.
- Risk factors include seizures, pneumonia, and pulmonary hypertension, often leading to hypoxic respiratory failure.
Observation:
- A case report details an 8-week-old infant diagnosed with malignant pertussis and severe complications.
- The infant presented with extreme leukocytosis (119,000/mm³), seizures, pneumonia, and pulmonary hypertension.
Findings:
- A one-volume blood exchange transfusion was administered.
- Following the transfusion, white blood cell count rapidly decreased to 36,500/mm³.
- The infant showed significant clinical improvement and a favorable outcome.
Implications:
- Early blood exchange transfusion may be a life-saving intervention for malignant pertussis.
- This procedure could help prevent fatal outcomes in severe pertussis cases.
- Further research into exchange transfusion for severe pertussis is warranted.
Objective:
To report early blood exchange transfusion in malignant pertussis and a favorable clinical outcome.
Setting:
A pediatric intensive care unit in a tertiary hospital in Geneva, Switzerland.
Design:
A descriptive case report.
Patient:
An 8-wk-old girl was diagnosed with malignant pertussis (extreme leukocytosis, seizures, pneumonia, and secondary severe hypoxic respiratory failure associated with pulmonary hypertension). After administration of a one-volume blood exchange transfusion, a rapid decrease in white blood cell count (from 119,000/mm(3) to 36,500/mm(3)) was observed and followed by clinical improvement and favorable outcome despite the initial presence of all described risk factors associated with a high mortality.
Conclusion:
The use of exchange blood transfusion early in the course of the disease might help to prevent a fatal outcome of malignant pertussis.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
