A 73-year-old male metalworker was admitted to our hospital with a 3-year history of progressive dry cough. Chest high-resolution computed tomography revealed emphysematous changes and reticular lesions, which is referred to as combined pulmonary fibrosis and emphysema (CPFE). Surgical lung biopsy specimens revealed unclassified interstitial pneumonia, including a nonspecific interstitial pneumonia pattern and usual interstitial pneumonia pattern. Two years after his first admission he developed rapid progressive renal dysfunction with an elevated level of myeloperoxidase-antineutrophil cytoplasmic antibody (428 EU). A renal biopsy specimen revealed interstitial nephritis and glomerulonephritis. Consequently, microscopic polyangiitis preceded by CPFE was diagnosed. Despite transient exacerbation of renal involvement, his general condition remained mostly stable during a 2-year period of corticosteroid treatment. He ultimately died from severe pneumococcal pneumonia associated with acute lung injury.

(Mp), a unique pathogen devoid of a cell wall, is naturally impervious to penicillin antibiotics. This bacterium is the causative agent of pneumonia, an acute pulmonary affliction marked by interstitial lung damage. Non-macrolide medications may have potential adverse effects on the developmental trajectory of children, thereby establishing macrolides as the preferred treatment for in pediatric patients.

Background: Lung transplantation (LuTX) can be the last resort for patients with end-stage lung diseases. In the last decades, improvements were implemented in transplant medicine, from immunosuppression throughout preservation of the donor organ to enhance lung allograft survival. This retrospective study aims to illustrate the development of the LuTX-program at the University Hospital of Munich, LMU, Munich, Germany, since its launch in 1990 by depicting and comparing postoperative outcome.
