ABSTRACT
PURPOSE OF REVIEW: Pregnancy for people with sickle cell disease (SCD) is high risk with persistently high rates of severe maternal and fetal mortality and morbidity. Transfusion therapy is the best-studied treatment for SCD in pregnancy; hydroxyurea is not usually used because of teratogenicity concerns. In high-resource settings, red cell transfusions are likely underutilized, while in low-resource settings, they may be altogether unavailable. RECENT FINDINGS: A randomized controlled trial and meta-analysis, two of the strongest forms of clinical research, show transfusion significantly reduces maternal and fetal death, painful crisis, thrombosis, and acute respiratory failure. Downstream benefits of treatment are less well measured and may include improving maternal anemia, reducing opioid exposure, and avoiding hospitalization, which presents risk for additional complications. Alloimmunization is a particular transfusion risk in SCD. However, many strategies can mitigate this risk. Accordingly, the American Society of Hematology classifies chronic transfusion in pregnancy as low risk. SUMMARY: Given the low risk classification, lack of alternative therapies, dismal, stagnant pregnancy outcomes and the potential for profound treatment benefit, wider use of chronic transfusion therapy for SCD pregnancy is likely indicated. This review discusses the benefits and potential risks of prophylactic transfusions for SCD pregnancy. Use of chronic transfusions during pregnancy is indicated to help urgently transform outcomes.
ABSTRACT
Mental illness is a common sickle cell disease (SCD) comorbidity. This observational study evaluated psychiatry appointment attendance among 137 young adults with SCD. In their first year of adult SCD care, 43% of subjects were referred to psychiatry. Referral was associated with chronic transfusion therapy. Twenty-four percent of subjects attended a psychiatry appointment; attendance was associated with the appointment being scheduled within 6 weeks of referral and no subject characteristics. Ninety-one percent of subjects attending psychiatry appointments had a psychiatric disorder. Among young adults with SCD, psychiatric morbidity is high. Psychiatric services are, therefore, essential for this patient population.

INTRODUCTION: Sickle cell disease (SCD), its treatments and cures present infertility risks. Fertility counseling is broadly indicated for affected girls and women and fertility preservation may appeal to some. Several streams of evidence suggest that the reproductive lifespan of women with SCD is reduced. Pregnancy is associated with high miscarriage rates. There are enduring questions about the effects of highly effective hydroxyurea treatment on female fertility. Current conditioning regimens for gene therapy or hematopoietic stem cell transplant are gonadotoxic. Fertility preservation methods exist as non-experimental standards of care for girls and women. Clinicians are challenged to overcome multifactorial barriers to incorporate fertility counseling and fertility preservation care into routine SCD care. AREAS COVERED: Here we provide a narrative review of existing evidence regarding fertility and infertility risks in girls and women with SCD and consider counseling implications of existing evidence. EXPERT OPINION: Addressing fertility for girls and women with SCD requires engaging concerns that emerge across the lifespan, acknowledging uncertainty and identifying barriers to care, some of which may be insurmountable without public policy changes. The contemporary SCD care paradigm can offer transformative SCD treatments alongside comprehensive counselling that addresses fertility risks and fertility preservation opportunities.

ABSTRACT: Data to guide evidence-based management of pregnant people with sickle cell disease (SCD) are limited. This international Delphi panel aimed to identify consensus among multidisciplinary experts for SCD management during pregnancy. The 2-round Delphi process used questionnaires exploring 7 topics (antenatal care, hydroxyurea use, transfusion, prevention of complications, treatment of complications, delivery and follow-up, and bottlenecks and knowledge gaps) developed by a steering committee. Thirteen panelists (hematologists, physiologists, obstetricians, maternal fetal medicine, and transfusion medicine physicians) from the United States, the United Kingdom, Turkey, and France completed the first survey; 12 panelists completed the second round. Anonymized responses were collected and summarized by a contract research organization (Akkodis Belgium). Consensus and strong consensus were predefined as 75% to 90% (9-10 of 12) and >90% (≥11 of 12) of panelists, respectively, agreeing or disagreeing on a response to a predefined clinical scenario or statement. In several areas of SCD management, consensus was achieved: experts recommended performing at least monthly multidisciplinary antenatal follow-up, administering prophylactic aspirin for preeclampsia prevention between gestational weeks 12 and 36, initiating prophylactic transfusion therapy in certain cases, or choosing automated red blood cell exchange over other transfusion methods for patients with iron overload or severe acute chest syndrome. No consensus was reached on several topics including the prophylactic aspirin dose, indications for starting infection prophylaxis, routine use of prophylactic transfusions, or use of prophylactic transfusions for preventing fetal complications. These recommendations could inform clinical care for patients with SCD who are pregnant in the absence of large clinical trials involving this population; the identified knowledge gaps can orient future research.
