title: Everolimus in lung transplantation in Chile.
abstract: Everolimus has shown good results in kidney and heart transplantation, achieving low rates of rejection, of infections, and of tumors compared with calcineurin inhibitors (CNI). Some publications have shown beneficial effects in bronchiolitis obliterans syndrome (BOS). We have presented herein the initial experience with everolimus among lung allograft recipients in Chile.
  
  
  METHODS
  We retrospectively evaluated, charts of lung-transplanted patients who used everolimus (Certican) based on 2 years' follow-up, evaluating the indication for therapy; blood levels, rejection episodes, lung and kidney function, and side effects.
  
  
  RESULTS
  Eight of 55 lung transplantation patients were switched to everolimus, targeting a (mean drug level of 4.2 ng/dL), in combination with low-dose tacrolimus (mean levels 5.5 ng/dL) and steroids. The Reasons for conversion were: CNI nephropathy (n = 3), BOS (n = 4), and lymphoma (n = 1). In patients with renal dysfunction, serum creatinine had risen from 1.1 to 1.8 mg/dl, but at 3 months after everolimus conversion, they had returned to baseline values, maintaining that level for at least 2 years' follow-up. Patients with BOS had decreased their ventricular ejection fraction (VEF(1)) by 50%. Using everolimus, they maintained that VEF(1) with little improvement. The patient with lymphoma died 11 months after conversion. No patient experienced a rejection episode, and they suffered from fewer infections than the other lung allograft recipients. There were no adverse events related to everolimus, but one patient discontinued the drug after 1 year owing to intolerance.
  
  
  CONCLUSIONS
  Everolimus was effective to reverse CNI renal dysfunction in lung transplantation patients, possibly retarding the progression of BOS, without side effects over a 2-year follow-up.
