Numerous pleuropulmonary consequences are linked with systemic lupus erythematosus. Although uncommon, diffuse alveolar haemorrhage (DAH) is a potentially fatal cause of abrupt respiratory failure in lupus patients. The study describes the case of a 24-year-old lady with lupus who experienced hemoptysis and respiratory failure as a result of widespread radiographic infiltrates and anaemia. DAH was verified by bronchoscopy. Her pulmonary haemorrhage and respiratory failure were successfully treated with supportive treatment, plasmapheresis, and immunosuppressive medication. 

It evaluates the literature on the aetiology and management of lupus-associated DAH, focusing on supportive care, coagulopathy reversal, and immunosuppressive therapies.
