[Uremic pneumonitis: a case report].

: Although lung involvement is frequent in patients with renal failure, cases of uremic pneumonitis have become less and less frequent since the introduction of dialysis. We describe the clinical case of a man who had respiratory distress and severe renal impairment when he first came to our observation. Instrumental and laboratory tests resulted in a diagnosis of advanced chronic renal failure together with extensive bronchopneumonia, while further tests revealed more severe lung involvement. After excluding the immunological pathogenesis forms involving the kidneys and lungs, our new diagnosis was uremic pneumonitis complicated by bronchopneumonia. The diagnosis was supported by the tomographic picture of the lung and the severe state of uremic poisoning, as well as an ex juvantibus criterion: intensive dialytic treatment together with broad-spectrum antibiotic therapy resulted in progressive improvement of the clinical picture with concurrent regression of the radiological lesions in the lung.
