Purpose: Currently, there is no consensus regarding the choice of anesthetic technique for parturients with sickle cell disease (SCD). The aim of the study was to determine the impact of the anesthetic technique on the occurrence of postnatal sickling complications.
Methods: We reviewed the charts of all pregnant women with SCD who had given birth in our institution between January 2002 and January 2007. Data related to pregnancy and anesthetic management and complications related, or unrelated, to SCD were recorded. Full blood count and lactate dehydrogenase values were recorded on the day of delivery. Risk factors for postnatal sickling complications were evaluated using a logistic regression analysis to estimate odds ratios (OR) and their 95% confidence intervals (95% CI).
Results: Fourteen of the 55 women (24%) experienced at least one postnatal sickling complication. Women who developed postnatal sickling complications were found to have a higher leukocyte count (17.0+/-6.1x10(9).L(-1) vs 12.8+/-4.4x10(9).L(-1), P=0.008) and a lower hemoglobin level (7.8+/-1.1 vs 8.9+/-1.0 g.dL(-1), P=0.002). General anesthesia (OR=16.0; 95% CI, 1.6 to 165.6) and a leukocyte count>or=15x10(9).L(-1) (OR=8.4; 95% CI, 1.6 to 44.5) were identified as risk factors. Neuraxial anesthesia and use of ephedrine were not identified as risk factors. There were no deaths.
Conclusion: Our study suggests that general anesthesia could be associated with postnatal sickling complications, even when the severity of illness was taken into account.

Background: Sickle cell disease (SCD) has evolved from a condition predominantly fatal in childhood to a chronic illness impacting many adults, including women of reproductive age. For females with SCD, pregnancy represents one of the greatest health threats, exacerbating existing health challenges and introducing new risks. Despite advancements in healthcare, routine screening for existing complications like pulmonary hypertension (PH) remains inconsistent, particularly in low- and middle-income countries (LMICs), where the prevalence of SCD is highest.

Article Synopsis
- β-thalassemia and sickle cell disease are common genetic blood disorders caused by mutations in the β-globin gene, leading to anemia and requiring treatments like blood transfusions and bone marrow transplants.
- New research is exploring the potential of inducing ε-globin expression, which was previously thought non-inducible postnatally, as a way to improve treatment outcomes for these conditions.
- The review highlights the need for further research into the mechanisms of ε-globin silencing and suggests future drug development initiatives to harness its therapeutic benefits.

Article Synopsis
- * The program has screened over 7,500 infants since September 2020, identifying 126 with SCD and 1,546 with sickle cell trait (SCT), with a significant percentage receiving genetic counseling and timely referrals for further care.
- * This initiative demonstrates that a sustainable SCD screening and counseling program can be effectively implemented even in low-income settings, improving outcomes for affected newborns and their families.

Introduction: The incidence of feto-maternal complications is high in women with sickle cell disease. The paucity of high-quality evidence has led to conditional recommendations for transfusional support in pregnant patients. This study aimed to assess if scheduled partial red cell exchanges impact pregnancy outcomes in sickle cell disease patients.
