Abstract
Immune thrombocytopenia (ITP) in pregnancy is challenging for both mother and fetus. Understanding the pathophysiology, treatments, and risks to the mother and fetus leads to proper management resulting in successful pregnancy and delivery in almost all cases.1 ITP in a pregnant woman has many similarities to ITP not in pregnancy although gestational thrombocytopenia can be confused with ITP. However, recognizing differences is instrumental in avoiding bleeding complications and toxicities of treatment. This Nutshell review focuses on the natural history of ITP in pregnancy, its treatment, and dilemmas.

Su K, Cheng H, Jia Z, Yuan Y, Yang H, Gao Q, Jiang Z, Wen H, Jiang J. Predictors of refractory risk in systemic lupus erythematosus-related thrombocytopenia: a dual-centre retrospective study. Lupus Sci Med 2022; 9:9/1/e000677. [PMID: 35606019 PMCID: PMC9125766 DOI: 10.1136/lupus-2022-000677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 05/09/2022] [Indexed: 11/17/2022]
Abstract
Objectives Based on clinical and laboratory indicators, this study aimed to establish a multiparametric nomogram to assess the risk of refractory cases of SLE-related thrombocytopenia (SLE-related TP) before systematic treatment. Methods From June 2012 to July 2021, a dual-centre retrospective cohort study of prospectively collected data of patients with SLE-related TP was conducted. The cohort data were divided into a developing set, internal validation set and external validation set. Refractory thrombocytopenia (RTP) was defined as failed to prednisone at 1 mg/kg per day with a platelet count cannot achieve or maintain higher than 50×109/L. In the developing set, a nomogram were established to predict RTP risk based on clinical characteristics and laboratory indicators by multivariable logistic regression, and its performance was assessed by receiver operating characteristic (ROC) curves, calibration curves, decision curve analysis (DCA) and clinical impact curve (CIC). Results A total of 1778 patients with SLE were included, and 413 eligible patients were involved in the final analysis with 121 RTPs. The RTP risk assessment (RRA) model was composed of five significant risk variables: pregnancy, severity of TP, complement 3, anticardiolipin antibody-immunoglobulin G and autoimmune haemolytic anaemia. In three datasets, the AUCs were 0.887 (95% CI 0.830 to 0.945), 0.880 (95% CI 0.785 to 0.975) and 0.871 (95% CI 0.793 to 0.949), respectively. The calibration curve, DCA and CIC all showed good performance of the RRA model. Conclusion The RRA model demonstrated good capability for assessing the refractory risk in SLE-related TP, which may be helpful for early identification and intervention.

Abstract
OBJECTIVE The aim of our study is to evaluate the risk of morbidity and mortality of splenectomy in pregnant women compared with non-pregnant women. MATERIALS AND METHODS We conducted a retrospective population-based matched cohort study using the Health Care Cost and Utilization Project, Nationwide Inpatient Sample database from 2003 to 2011. Pregnant women with splenectomy were age-matched to non-pregnant women with splenectomy. We compared risks of morbidity and mortality between pregnant and non-pregnant women using conditional logistic regression analysis. RESULTS The non-pregnant group had an excess of white patients and a greater proportion of Medicaid and private insurance users. There was a tendency for greater frequency of laparotomies in pregnant patients. Risk of VTE, portal vein thrombosis, renal failure and sepsis were comparable between the groups. Risk for transfusion was higher amongst pregnant women (OR 2.2, 95% CI (1.7-2.8)), as was the risk for a longer hospital stay (OR 1.7, 95% CI (1.4-2.1)). CONCLUSION Caution should be taken when performing splenectomy during pregnancy as risk for complications and mortality may be increased. Additional measures should be undertaken to have blood units on reserve for this population.
