Chest radiographs demonstrates interstitial pneumonia with patchy alveolar infiltrates suggestive of multiple bleeding sites. Urinalysis is positive for blood and protein. A positive result is returned for anti-glomerular basement membrane antibody anti-GBM Ab. What is the most likely diagnosis?? A: Systemic lupus erythematous SLE, B: Granulomatosis with polyangiitis Wegners, C: Microscopic polyangiitis, D: Churg-Strauss syndrome, E: Goodpasture disease,  <response>: This is a clinical vignette describing a 27-year-old male with coughing up blood, interstitial pneumonia on chest x-ray, blood and protein in the urine, and a positive anti-GBM antibody test. The key findings are hemoptysis, pulmonary hemorrhage on imaging, glomerulonephritis evidenced by blood and protein in the urine, and a positive anti-GBM antibody. Anti-GBM disease, also known as Goodpasture syndrome, is characterized by pulmonary hemorrhage and glomerulonephritis due to autoantibodies against the glomerular basement membrane. The pulmonary-renal syndrome along with the positive anti-GBM antibody make Goodpasture disease the most likely diagnosis. SLE can cause pulmonary hemorrhage but anti-GBM antibody would not be expected. The other vasculitides may cause pulmonary hemorrhage but would not explain the positive anti-GBM antibody or glomerulonephritis.E: Goodpasture disease
