- Abstract
Background: Splenectomy is a therapy for patients with treatment‐refractory autoimmune cytopenias. Antiphospholipid antibodies (aPL) can be identified in 25%–85% of these patients. In this study, we sought to identify whether the presence of aPL was associated with worse outcomes in autoimmune cytopenia's patients who had undergone splenectomy. Methods: We conducted a retrospective cohort study of patients who underwent splenectomy from 2000 to 2018. We describe clinical characteristics and outcomes in patients with autoimmune cytopenia's diagnosis with positive determinations of aPL. Additionally, we performed a case–control sub‐analysis 1:1 of the cases with autoimmune cytopenia's matched control patients with negative aPL determination. Results: A splenectomy was performed in 707 patients, of which we included 34 for the analysis. The median age at the time of splenectomy was 37 years (range 19–61), 53% corresponded to immune thrombocytopenia (ITP) and 47% to autoimmune hemolytic anemia (AIHA). Compared with controls (n = 34), patients had more treatment lines in addition to steroids (p =.02). There were no differences in complete response rate, 65% in cases and 80% in controls (p =.17). However, there was numerically a higher incidence of early infections (21% of cases vs. 3% controls, p =.05). During the entire follow‐up, 15% of aPL patients compared with 9% of control patients had a thrombotic event (p =.70). Discussion: Splenectomy for treatment‐refractory autoimmune cytopenia's patients with persistent aPL is an effective treatment despite some safety concerns related to early infections. These results suggest that the presence of aPL should not impact the decision to undergo splenectomy.
