Background/Objective: Diffuse alveolar hemorrhage (DAH) is an uncommon but potentially fatal complication in patients with systemic lupus erythematosus (SLE). Its prognosis and factors associated with mortality are not completely clear, although invasive mechanical ventilation (IMV), use of cyclophosphamide, a high Acute Physiology and Chronic Health Evaluation II score, and infections are associated with high mortality rates. We investigated clinical and immunologic characteristics and factors associated with mortality in a cohort of Latin American patients with SLE who developed DAH. Methods: Amedical records review studywas conducted of patientswith SLEwhowere admitted to the intensive care unit (ICU) withDAHbetween 2011 and 2018. Clinical, laboratory, and treatment variables were compared between survivors and nonsurvivors. Results: A total of 17 patients with SLE presented with DAH during the study period, of whom 11 (64.70%) were women. The median age was 28 (19-38.5) years. The Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) on admission to the ICU was 15.94 +/- 10.07. All patients received pulse methylprednisolone and therapeutic plasma exchange, and 13 (76. %) also received cyclophosphamide. During the hospital stay, 5 patients (29.41%) died. A high SLEDAI on admission, low albumin, and days of IMVand inotropic/vasoactive support were statistically significant in comparing nonsurvivors with survivors. Other scales of disease severity commonly used in the ICU, however, were not significantly associated with a fatal outcome. Conclusions: Hypoalbuminemia, longer duration of IMV or inotropic/vasoactive treatment, and a high SLEDAI are potential prognostic factors for mortality in patients with SLE and DAH admitted to the ICU.
