Pulmonary hemorrhage-nephritis syndrome

Pulmonary hemorrhage-nephritis syndrome may be a viral infection and / or inhalation of certain chemicals causing primary lung damage. Due to the presence of cross-reactive antigens in the alveolar wall capillary basement membrane and the glomerular basement membrane, secondary renal injury can be caused. The disease occurs in young men, with a male to female ratio of 9: 1. Patients under 16 years of age are rare.
