Nutrition in the pediatric double lung transplant patient with cystic fibrosis
Insights
Nutritional status is critical for pediatric cystic fibrosis (CF) patients post-lung transplant. Gastrostomy tube feeding aids weight gain more effectively than oral intake for improved outcomes in CF patients.
Area of Science:
- Pulmonology
- Genetics
- Pediatrics
Background:
- Cystic fibrosis (CF) is a lethal genetic disease impacting pulmonary and pancreatic function.
- Malnutrition affects approximately 50% of CF patients, complicating disease management.
- Nutritional status is crucial for CF patients, especially post-transplant.
Purpose of the Study:
- To evaluate the nutritional status of pediatric cystic fibrosis patients after double lung transplantation.
- To compare weight gain and feeding methods in post-transplant CF patients.
Main Methods:
- Retrospective analysis of 10 pediatric CF patients undergoing double lung transplant.
- Assessment of nutritional status, weight gain, and feeding modalities (gastrostomy tube vs. oral intake).
- Comparison of outcomes based on survival duration post-transplant.
Main Results:
- Patients surviving over 1 year post-transplant showed significantly faster weight gain.
- Gastrostomy tube feedings were more effective for post-transplant weight gain compared to oral intake.
- CF patients with pancreatic insufficiency experienced challenges in adjusting immunosuppressive medications.
Conclusions:
- Optimizing nutritional status, particularly through gastrostomy tube feeding, is vital for pediatric CF patients after lung transplantation.
- Further research is needed to understand medication adjustment difficulties in CF patients with pancreatic insufficiency.
Abstract:
Cystic fibrosis (CF) is the most common lethal genetic disease in the white population. The pulmonary infections and pancreatic insufficiency make CF a medically challenging disease. Although the importance of nutrition in the CF patient is known, approximately 50% of CF patients are in less than the 10th percentile for weight and height as reported by the 1991 CF Foundation Registry of 114 CF Centers in the United States. This paper addresses the nutritional status of 10 pediatric CF patients who underwent double lung transplant at Children's Hospital of Pittsburgh between August 1991 and May 1993. Patients who survived beyond 1 year gained a significant amount of weight sooner after transplant than those who survived less than 1 year. Gastrostomy tube feedings were more effective than oral intake for weight gain after transplant. CF patients with pancreatic insufficiency have more difficulty with adjustment of doses of immunosuppressive agents for reasons that are not clearly understood.
