Insights
Bacillus Calmette-Guérin (BCG) osteomyelitis is a rare complication in infants. Early diagnosis and treatment are crucial for managing this serious BCG vaccine side effect in children.
Area of Science:
- Pediatrics
- Infectious Diseases
- Vaccinology
Background:
- The Bacillus Calmette-Guérin (BCG) vaccine is widely administered to newborns globally, including in the UAE, for disease prevention.
- BCG osteomyelitis, a rare but serious complication, necessitates consideration in pediatric osteomyelitis cases.
Observation:
- This report details three pediatric cases of BCG osteomyelitis in the UAE, affecting the humerus and tibia in immunocompetent infants.
- The cases highlight the insidious clinical presentation, emphasizing the need for vigilance.
Findings:
- Diagnostic approaches include detailed radiologic, microbiologic, and histologic evaluations.
- The report outlines the specific treatment regimens employed for these patients.
Implications:
- This case series aims to enhance physician awareness of BCG osteomyelitis.
- Prompt recognition and early intervention are critical for favorable patient outcomes.
Abstract:
Bacillus Calmette-Guérin (BCG) vaccine is a live attenuated vaccine used globally since 1921, and in the United Arab Emirates (UAE), it is administered to all newborns within the first few days of life for well-established benefits. BCG osteomyelitis is a rare complication that should be considered while assessing osteomyelitis in children. This report describes three cases of BCG osteomyelitis involving proximal metaphysis of the humerus in 11 months and three months old immunocompetent male infants and the left proximal tibia in a two-year-old immunocompetent female. To the best of our knowledge, these are the first cases to be reported in the UAE. The report outlines in detail how to make a timely diagnosis by explaining the insidious clinical presentation of BCG osteomyelitis, including its radiologic, microbiologic, and histologic aspects. As well, it outlines the treatment course carried out for these three patients. As such, this report will aid physicians in staying vigilant for such rare complication and commencing early treatment.

Development of Immunocompetence
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.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
