    Abstract:
    OBJECTIVE: Despite aggressive therapeutic regimens, diffuse alveolar haemorrhage (DAH) is still associated with a high mortality rate in systemic lupus erythematosus (SLE). This study was carried out in patients with SLE-associated DAH with a focus on their therapeutic modality. METHOD: A retrospective review was performed in 839 Han Chinese lupus patients hospitalized for their DAH manifestation from May 2006 to December 2016. RESULTS: There were 24 episodes in 17 cases (2.0% incidence), 15 females and two males aged 19-67 years (mean ± sd 38.2 ± 15.1 years). High disease activity [Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) 12-31, 19.8 ± 5.6] was found at the onset of DAH. All patients were treated with high-dose corticosteroid, followed by pulse methylprednisolone (70.6%), plasmapheresis (41.2%), pulse cyclophosphamide (35.3%), and rituximab (23.5%). Six patients (35.3%), including three with extracorporeal membrane oxygenation, died owing to acute respiratory failure. All patients receiving rituximab treatment survived with a follow-up period of 12-58 months (40.8 ± 21.1 months), and no further relapse was noted in three cases with a history of recurrent DAH episodes. In addition, there was a significant decrease in their lupus activity (SLEDAI-2K 21.5 ± 6.0 to 6.3 ± 1.7, p = 0.0286). CONCLUSION: In this single-centre series with SLE-associated DAH in Han Chinese patients, a beneficial effect of rituximab therapy was observed.
