Over forty years, pediatric pneumology and allergology have undergone a profound transformation, moving from simple symptom recognition to a deep understanding of the mechanisms behind childhood respiratory diseases. The University Children's Hospital Reine Fabiola (HUDERF), since its opening in 1986, has been at the forefront of these major advancements.
Initially, the discipline was young with limited diagnostic tools, relying heavily on clinical examination. The 1990s marked a turning point with the development of respiratory function tests and flexible bronchoscopy, enabling more precise measurements and less invasive explorations. Allergology also progressed with specific IgE blood tests, improving allergy identification.
The discovery of the CFTR gene in 1989 was a crucial milestone for cystic fibrosis, paving the way for understanding its biological mechanisms and, over twenty years later, for the development of targeted treatments. This approach, focused on understanding causes rather than merely alleviating consequences, now characterizes the specialty.
HUDERF has structured itself as a reference center for complex conditions such as severe asthma, complex allergies, and rare respiratory diseases. Multidisciplinary teams, including nurses, physiotherapists, dietitians, and psychologists, now provide comprehensive care, aiming not only to improve respiratory health but also growth, schooling, and autonomy.
The 2000s saw the rise of personalized medicine, with the understanding that similar diagnoses could hide distinct inflammatory and biological profiles. Asthma and allergies are now approached based on each child's individual profile, thanks to molecular diagnostics and new therapeutic strategies like immunotherapy and oral tolerance induction.
The most spectacular therapeutic revolution concerns cystic fibrosis, with the advent of CFTR modulators in the 2010s. These treatments directly target the disease mechanism, radically transforming patients' quality of life and future prospects. Transitioning to adult care teams is now a standard part of the treatment pathway.
New challenges are emerging, such as air pollution, indoor air quality, and adolescent vaping, requiring constant vigilance and adapted prevention strategies. Pediatric pneumology must continue to anticipate behaviors and environments that will shape the respiratory health of future generations.
In summary, pediatric pneumology-allergology has evolved from a medicine with limited tools to a cutting-edge discipline capable of finely measuring respiratory function, exploring immunological and genetic mechanisms, and offering targeted treatments. The ultimate goal remains to enable children not only to breathe better but, more importantly, to grow, study, become independent, and build their lives with the fewest possible limitations.
