Tuberculosis in children.

Area of Science:

• Pediatrics
• Infectious Diseases
• Public Health

Background:

• Tuberculosis (TB) remains a significant global health threat, particularly impacting children who account for 5-15% of all cases.
• Severe forms like TB meningitis and disseminated TB are more prevalent in pediatric populations, leading to substantial mortality and morbidity.
• An estimated 67 million children have latent TB, with a high annual incidence of active disease development.

Purpose of the Study:

• To summarize the epidemiology, clinical manifestations, and diagnostic approaches for tuberculosis in children.
• To highlight the importance of early detection and intervention in preventing severe TB outcomes in pediatric populations.
• To underscore the role of vaccination in mitigating life-threatening forms of childhood TB.

Main Methods:

• Review of epidemiological data and clinical characteristics of pediatric TB.
• Analysis of diagnostic methods, including gastric aspirates for pulmonary TB detection in young children.
• Evaluation of the impact of BCG vaccination on preventing severe TB forms.

Main Results:

• Children represent a substantial proportion of TB cases, with high mortality rates, especially from severe forms like meningitis and disseminated TB.
• Pulmonary TB is the most common form, but extrapulmonary and disseminated disease occur frequently in children under 3.
• Early morning gastric lavage is the preferred diagnostic sample for pulmonary TB in children under six.

Conclusions:

• Tuberculosis in children often presents with non-specific symptoms, necessitating a high index of suspicion for diagnosis.
• Early diagnosis and treatment are critical to prevent severe disease progression and mortality in pediatric TB.
• BCG vaccination plays a vital role in protecting children against severe and life-threatening forms of tuberculosis.
