Circulation, Volume 146, Issue Suppl_1, Page A9995-A9995, November 8, 2022. Objective:Anemia is a common comorbidity during pregnancy and in non-pregnant females of childbearing age. Our goal was to ascertain its association with in-hospital mortality and complications in females with peripartum cardiomyopathy (PPCM).Methods:The national inpatient sample was retrospectively queried from 2011-2017 to identify all women aged 17 to 51 years with the diagnosis of PPCM. We further identified diagnosis of anemia within each admission using ICD-10 codes (D64.9 and D64.89). Primary outcome was inpatient mortality rate while secondary outcomes were in-hospital complications such as acute kidney injury (AKI), pulmonary edema and antepartum hemorrhage. Demographic (age, sex, race) and clinical (history of hypertension, stroke, myocardial infarction, obesity, smoking) data was also noted. Analysis was conducted using STATA 16.0. Adjusted odds ratios (AOR) were calculated with multivariate logistic regression method reported with confidence interval (CI) and a P-value (significance

Too few US children with sickle cell anemia receive recommended screening or treatment despite the risk of life-threatening complications, according to a new CDC Vital Signs report.

Stroke, Ahead of Print. BACKGROUND:Hemorrhagic stroke in young patients with sickle cell anemia remains poorly characterized.METHODS:The Post-STOP (Stroke Prevention Trial in Sickle Cell Anemia) retrospective study collected follow-up data on STOP and STOP II clinical trial cohorts. From January 2012 to May 2014, a team of analysts abstracted data from medical records of prior participants (all with sickle cell anemia). Two vascular neurologists reviewed data to confirm hemorrhagic strokes defined as spontaneous intracerebral, subarachnoid, or intraventricular hemorrhage. Incidence rates were calculated using survival analysis techniquesRESULTS:Follow-up data were collected from 2850 of 3835 STOP or STOP II participants. Patients (51% male) were a median of 19.1 (interquartile range, 16.6–22.6) years old at the time of last known status. The overall hemorrhagic stroke incidence rate was 63 per 100 000 person-years (95% CI, 45–87). Stratified by age, the incidence rate per 100 000 person-years was 50 (95% CI, 34–75) for children and 134 (95% CI, 74–243) for adults >18 years. Vascular abnormalities (moyamoya arteriopathy, aneurysm or cavernous malformation) were identified in 18 of 35 patients with hemorrhagic stroke.CONCLUSIONS:The incidence rate of hemorrhagic stroke in patients with sickle cell anemia increases with age. Structural vascular abnormalities such as moyamoya arteriopathy and aneurysms are common etiologies for hemorrhage and screening may be warranted.

Stroke, Ahead of Print. Background:Cerebral arteriopathy in patients with sickle cell anemia mainly affects the intracranial anterior circulation. However, the extracranial internal carotid artery (eICA) can also be stenosed and responsible for ischemic lesions. In children with sickle cell anemia, we perform routine annual Doppler ultrasound assessment of the eICA and magnetic resonance imaging with 3-dimensional time-of-flight magnetic resonance angiography of the Willis circle and neck arteries in those with abnormal velocity. Our aim was to report the evolution of eICA stenoses from 2011 to the present as a function of therapy in a retrospective case-series study. We hypothesized that chronic transfusion (CTT) would be more effective than hydroxyurea and simple observation on the evolution of eICA stenosis.Methods:Eligibility criteria were a history of eICA velocity ≥160 cm/s with a minimum Doppler and magnetic resonance imaging follow-up of 1 year. eICAs were graded for stenosis according to NASCET (The North American Symptomatic Carotid Endarterectomy Trial). Magnetic resonance imaging was investigated for ischemic lesions. Treatment with hydroxyurea and CTT were obtained from the chart review.Results:Fifty-four patients were included. Eight patients had a stroke history. The median (range) follow-up was 4.7 years (1.1–9.2 years). On the first neck magnetic resonance angiography, stenosis was present in 48/54 (89%) patients. Kinking was found in 39/54 (72%) patients. On the last neck magnetic resonance angiography, the proportion of patients with eICA stenosis decreased to 39/54 (72%). ICA occlusion occurred in 5 patients despite CTT. Three patients had carotid webs without intracranial stenosis. The proportion of patients with improvement in stenosis score was 8% with no treatment intensification, 20% with hydroxyurea, and 48% with CTT (P=0.016). The mean (SD) change per year in stenosis score was 0.40 (0.60) without intensification, 0.20 (0.53) with hydroxyurea, and −0.18 (0.55) with CTT (P=0.006). Ischemic lesions were present initially in 46% of patients, and the incidence of progressive ischemic lesions was 2.5 events/100 patient-years. Cox regression analysis showed that the initial score for eICA stenosis was a significant predictive factor for the risk of new silent cerebral infarct events.Conclusions:Our study reinforces the need to assess cervical arteries for better prevention of cerebral ischemia and encourage initiation of CTT in sickle cell anemia children with eICA stenosis.
