Abstract
BACKGROUND Critical bleeding events in adults and children with ITP are medical emergencies; however, evidence-based treatment protocols are lacking. Due to the severe thrombocytopenia, (typically platelet count less than 20 × 109/L), a critical bleed portends a high risk of death or disability. We plan to perform a systematic review and meta-analysis of treatments for critical bleeding in patients with ITP that will inform evidence-based recommendations. METHODS Literature searches will be conducted in four electronic databases: Ovid MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and PubMed. Eligible studies will be randomized controlled trials or observational studies that enrolled patients with ITP describing one or more interventions for the management of critical bleeding. Title and abstract screening, full-text screening, data extraction, and risk of bias evaluation will be conducted independently and in duplicate using Covidence and Excel. Outcomes will be pooled for meta-analysis where appropriate or summarized descriptively. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology will be used to evaluate the certainty of the evidence. Primary outcomes of interest will include frequency of critical bleeds, mortality and bleeding-related mortality, bleeding resolution, platelet count, and disability. DISCUSSION Evidence-based treatments for critical bleeding in patients with ITP are needed to improve patient outcomes and standardize care in the emergency setting. SYSTEMATIC REVIEW REGISTRATION CRD42020161206.

Abstract
INTRODUCTION Intracerebral hemorrhage (ICH) is a devastating complication of immune thrombocytopenic purpura (ITP). Using a large database, we sought to determine its incidence and mortality. METHODS We used a de-identified database (TriNetX) to gather information on patients with ITP with subsequent ICH (cohort 1), propensity score-matched with patients with ITP and no ICH (cohort 2). Primary endpoint was mortality, with secondary endpoints of percutaneous endoscopic gastrostomy (PEG) placement, craniotomy, palliative care encounters, intensive care unit (ICU) management, seizure, falls, pulmonary embolism (PE), myocardial infarction (MI), deep venous thrombosis (DVT), ischemic stroke (IS), and other venous embolism and thrombosis (VTE). RESULTS Incidence of ICH in patients with ITP was 1.540% in all ages, and 0.774% in those under age 18. After matching, 942 patients from each cohort were identified. Mean age was 58.3 years versus 61.2 years in cohort 1 and 2, respectively. Mortality rate was 34.076% vs. 20.17% (p <0.0001, OR 2.046 with 95% CI 1.661,2.520) at five years. Thirty-day survival was 83.46% vs. 95.17% (p<0.0001), and 365-day survival 68.59% vs. 85.33% (p<0.0001). PEG placement was seen in 21 (2.229%) patients in cohort 1, and less than 10 patients (<1.062%) in cohort 2 (p<0.0464). 2.442% vs. 0% underwent craniotomy (p<0.0001), palliative care was involved in 15.711% vs. 7.962% (p<0.0001), ICU care was seen in 27.389% vs. 11.783% (p<0.0001), with a mean ICU stay of 8.075 vs. 5.812 days (p=0.0537). 6.582% vs. 3.715% had PE (p=0.0049), 7.643% vs. 7.113% experienced MI (p=0.6595), 9.236% vs. 4.883% had DVTs (p=0.0002), 23.673% vs. 5.732% had seizures (p<0.0001), 9.023% vs. 6.582% suffered falls (p=0.0482), 7.537% vs. 3.503% suffered IS (p<0.0001), and 15.074% vs. 8.174% experienced other VTE (p<0.0001). CONCLUSION ICH occurs in approximately 1.54% of ITP patients, and is associated with a 34% mortality rate, increased PEG tube placement rates, palliative care involvement, ICU care, craniotomy, PE, IS, DVT, seizures, and falls.
