  18. Criteria for entry into the list Expected survival6 months-2 years, New-York Hearth association (NYHA) class III and IV levels function NYHA Functional Classification • NYHA Class III: moderate, significant limitation in physical activity, but the rest is easy, less activity than usual causes symptoms• NYHA Class IV: severe, can not do any physical activity without any problems,orthopnea or paroxysmal Symptoms such as nocturnal dyspnea can be found at rest

  19. Other Criterias Patients on Technological support Nitric-oxide inhalation Extracorporeal membran oxygenation

  20. Reviews needed Blood examination • Hemogram, Hemostasis • Blood group • Urea, Ions, creatinin • Blood glucose • Liver functions • Lipids • Thyroid functions • HLA typing

  21. Radiological examinations • Chest x-ray • Thorax, abdominal tomography • Abdominal ultrasound • Ventilation/Perfusion scintigraphy • Sinusal tomography (for CF)

  22. Functional Examinations Lung Pulmonary function tests, diffusion capacity Blood gases 6 sec. walking test Heart EKG, ECHO, bone-mineral density

  23. Searching for Infections • Sputum, culture-antibiogram • Detection of mycobacteria • PPD • Urine analysis • Culture for MRSA • HIV, Hepatitis B and C serology • EBV • Chlamydia pneumoniae • Varicella zoster serology

  24. Evaluation of malignancy • Sputum cytology • Papanicolau smear • Prostate-specific antigen • Mammography • Blood in stool

  25. Assessment of autoimmunity • ANA, RF • DNA antibody • ANCA • Creatinin kinase • Immunoglobulins

  26. Consultations • Dental •  Gastro • Dermatology • Psychiatry • Nutrition • Ear-Nose-Throat (ENT) • Physiotherapy

  27. Patient Selection Criterias

  28. Cystic Fibrosis • Basic illness requirements for lung transplantation in children, adolescent and young adults

  29. CF and Bronchiectasis • FEV1 < %30 and progressive decline • PCO2 > 55 mmHg • PO2 < 50 mmHg • increased egzazerbation despite treatment with antibiotics • Refractory and / or recurrent pneumothorax • Uncontrolled Hemoptysis Am. J.of Transpl. 2007;7:285-92

  30. Idiopathic Pulmonary Hypertension • NYHA or WHO class III-IV findings • Low response to 6 sec. walking test • Uncontrolled syncope • Hemoptysis • Right heart failure Hearth, Lung Transplant 2006;25:745-55

  43. Immunologic Complications Acute rejection: 1 week-1 month Asymptomatic Fever, dyspnea, hypoxia X-ray, bilateral infiltrasyon Decline in FEV1 and FVC Diagnosis: Bronchoscopy, BAL, TB. Biopsy (A0-A4 grade) Chronic rejection: Several months later Am.J.of Transplant 2007;285-92

  44. Acute rejection • Often seen after transplantation • Reported over 50% • Symptoms of fever and malaise • However, many patients with minimal symptoms • Transbronchial biopsy:

  45. Bronchiolitis Obliterans The most feared complication of long-term 50% in the first five years Post-transplant deaths: 40% in the first year Development is not clear Lower risk of developing in live-donor transplant Diagnosis: biopsy, HRCT, Vent. / Perf. Scintg. Treatment: immunosuppressiveEur.resp. J. 2004;24:839-45 Am.J.of Transplant 2007;7:285-89

  47. Malignancy 6.5% in the first 1 year In five years, 8.5% Lymphoma EBV infection is a risk Treatment: reduction of immunosuppressionCD20 monoclonal antibody
