Bronchiectasis diagnosed after renal transplantation: a retrospective multicenter study

Area of Science:

• Pulmonology
• Nephrology
• Transplantation Medicine

Background:

• Bronchiectasis involves irreversible airway dilation, causing significant respiratory symptoms and complications.
• While causes are known, the link between bronchiectasis and renal transplantation is under-researched.

Purpose of the Study:

• To investigate the occurrence and characteristics of bronchiectasis in patients post-renal transplantation.
• To identify potential clinical and radiological features associated with post-transplant bronchiectasis.

Main Methods:

• A retrospective multicenter study involving 14 French renal transplantation departments.
• Data collected included demographics, clinical presentation, laboratory results, and CT scan findings for patients diagnosed with bronchiectasis after transplantation.

Main Results:

• Forty-six patients were analyzed; autosomal dominant polycystic kidney disease was the most common underlying renal condition.
• Chronic cough and sputum were primary symptoms; Haemophilus influenzae was the predominant identified microorganism.
• Hypogammaglobulinemia was frequent, and bronchiectasis was often extensive with a significant apex-to-base gradient.

Conclusions:

• Bronchiectasis should be suspected in renal transplant recipients experiencing new respiratory symptoms.
• Further research is necessary to elucidate the mechanisms driving bronchiectasis development in this patient population.
