Insights
A 13-year-old with cystic fibrosis (CF) experienced severe lung infection. Surgical removal of the affected lung led to significant, long-term improvement in quality of life.
Area of Science:
- Pulmonology
- Nephrology
- Surgical Oncology
Background:
- Cystic Fibrosis (CF) is a genetic disorder primarily affecting the lungs, leading to chronic infections and progressive lung damage.
- Lung disease is the leading cause of mortality in adult CF patients, with lung transplantation being the standard treatment for severe bilateral disease.
- Comorbidities like nephrotic syndrome and secondary amyloidosis can complicate CF management.
Observation:
- A 13-year-old male with CF presented with a severe right-sided lung infection, including abscess formation and localized bronchiectasis.
- The patient's condition was further complicated by nephrotic syndrome and secondary amyloidosis.
- Unilateral pneumonectomy (surgical removal of one lung) was performed to address the severe, localized lung disease.
Findings:
- The pneumonectomy resulted in significant clinical improvement for the patient.
- A remarkable increase in the patient's quality of life was observed post-surgery.
- These positive effects have been sustained for 15 years following the procedure.
Implications:
- Surgical resection of severely affected unilateral lung segments offers a viable rescue therapy option for CF patients.
- This approach is particularly relevant for patients with localized bronchiectasis or those at high risk of mortality while awaiting lung transplantation.
- Pneumonectomy can significantly improve long-term outcomes and quality of life in select CF cases with unilateral lung disease.
Abstract:
We present the case of a 13-year-old boy with cystic fibrosis (CF) who developed severe right-sided lung infection with formation of abscess and localized bronchiectasis. The boy's lung disease was complicated by nephrotic syndrome and secondary amyloidosis. Unilateral pneumonectomy was performed, producing significant clinical improvement with a remarkable increase in quality of life which has lasted to the present date, 15 years later. Most patients with CF develop lung disease, which is the main cause of adult mortality in this population. Lung transplantation is currently considered the treatment of choice in severe bilateral lung disease in CF. However, in severe unilateral lung disease such as localized bronchiectasis, surgical resection of the affected lobe or lung is still a worthwhile option as a rescue therapy for patients who are at high risk of dying while waiting for lung transplantation.

Cystic Fibrosis: Pathogenesis
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
