Association Between Platelet Transfusion and Mortality Rate Among Preterm Neonates in the Eastern Province, Saudi Arabia

Survival Rates of Extremely Low-Birth-Weight Infants in a Tertiary Care Center in Saudi Arabia

Introduction Extremely low birth weight (ELBW) refers to the condition in which an infant is born with a weight of less than one thousand grams (2.2 pounds) at birth. ELBW infants face significant challenges and are at increased risk for various medical complications and developmental issues. ELBW poses unique challenges for infants, families, and healthcare providers. Understanding the causes, consequences, and appropriate management strategies for ELBW is crucial for improving the survival rates of these vulnerable infants. Aim This study aimed to measure the survival rates of ELBW infants in Saudi Arabia and its correlated risk factors. Patients and methods This case-control study was a retrospective chart review analysis of data from King Abdulaziz Medical City (KAMC), a single tertiary care center in Riyadh, Kingdom of Saudi Arabia, and conducted over a four-year period. To estimate the survival rate among all live-birth newborn infants who were born with ELBWs of less than 1000 grams, collected data were tabulated and cleaned in MS Excel, and all data were analyzed using IBM SPSS Statistics for Windows, version 26 (released 2019; IBM Corp., Armonk, New York, United States). Results Two hundred and fifty-six patients were involved. Non-survival rates were 12.9%. In a multivariate regression model, prolonged rupture of membranes (PROM), periventricular leukomalacia (PVL), major intraventricular hemorrhage (IVH), and longer length of stay had increased risks for non-survival, while increasing gestational age, APGAR scores, and cesarean section had decreased risks for non-survival. Survival analysis found that there was a significant mean difference in gestational age (weeks) survival time between normal spontaneous vaginal delivery (NSVD) and cesarean section based on log-rank (Mantel-Cox) (p = 0.008). Conclusion Consistent with the literature, a greater prevalence of ELBW infants survived during hospital stay. Independent risk factors for non-survival include PROM, PVL, major IVH, and long length of stay. Cesarean section, increasing gestational, and APGAR scores were identified as the independent predictors of survival. Prospective studies in nature are required to determine these factors' cause and effect.

Platelet transfusion practices among neonatologists in Saudi Arabia: A nationwide cross-sectional survey

The etiologies of thrombocytopenia are highly diverse; however, early neonatal thrombocytopenia might be more common among extremely low-weight neonates. Therefore, in this study, we aimed to examine the current neonatal platelet (PLT) transfusion practices in Saudi Arabia. This is a cross-sectional online survey study that was conducted between October and December 2022. Convenience sampling was used to recruit the participants. In this study, we developed a questionnaire based on an extensive literature review to examine current neonatal PLT transfusion practices. A total of 81 neonatologists participated. The vast majority of them (85.2%) were practicing in a level 3 neonatal intensive care unit, with 60.0% of them reporting that they transfuse PLTs over 1 hour. Around 53% reported that they typically order 10 mL/kg per PLT transfusion. Up to 34.6% of the study participants reported that they use pooled whole-blood-derived PLT products in their practicing unit. Almost half (48.0%) of the study participants reported that they have written guidelines for PLT transfusion in their practicing unit, with 81.1% reporting that the PLT transfusion threshold was stated in the guidelines. Neonatal thrombocytopenia is typically treated with PLT transfusions. PLT transfusion criteria should be lowered in light of recent evidence suggesting that doing so may be counterproductive. However, there is some disagreement about whether a PLT count constitutes a medical emergency requiring a transfusion for a newborn baby. Furthermore, there is a great deal of variation in the administration of PLT infusions in Saudi Arabia because of the absence of clear protocols. Strict neonatal PLT transfusion standards and carefully planned clinical research are needed to address the risks and/or benefits of these diverse methods.

Platelet transfusions in preterm infants: current concepts and controversies-a systematic review and meta-analysis

Platelet transfusions (PTx) are the principal approach for treating neonatal thrombocytopenia, a common hematological abnormality affecting neonates, particularly preterm infants. However, evidence about the outcomes associated with PTx and whether they provide clinical benefit or harm is lacking. The aim of this systematic review and meta-analysis is to assess the association between PTx in preterm infants and mortality, major bleeding, sepsis, and necrotizing enterocolitis (NEC) in comparison to not transfusing or using different platelet count thresholds for transfusion. A broad electronic search in three databases was performed in December 2022. We included randomized controlled trials, and cohort and case control studies of preterm infants with thrombocytopenia that (i) compared treatment with platelet transfusion vs. no platelet transfusion, (ii) assessed the platelet count threshold for PTx, or (iii) compared single to multiple PTx. We conducted a meta-analysis to assess the association between PTx and mortality, intraventricular hemorrhage (IVH), sepsis, and NEC and, in the presence of substantial heterogeneity, leave-one-out sensitivity analysis was performed. We screened 625 abstracts and 50 full texts and identified 18 reports of 13 eligible studies. The qualitative analysis of the included studies revealed controversial results as several studies showed an association between PTx in preterm infants and a higher risk of mortality, major bleeding, sepsis, and NEC, while others did not present a significant relationship. The meta-analysis results suggest a significant association between PTx and mortality (RR 2.4, 95% CI 1.8-3.4; p < 0.0001), as well as sepsis (RR 4.5, 95% CI 3.7-5.6; p < 0.0001), after a leave-one-out sensitivity analysis. There was also found a significant correlation between PTx and NEC (RR 5.2, 95% CI 3.3-8.3; p < 0.0001). As we were not able to reduce heterogeneity in the assessment of the relationship between PTx and IVH, no conclusion could be taken.    Conclusion: Platelet transfusions in preterm infants are associated to a higher risk of death, sepsis, and NEC and, possibly, to a higher incidence of IVH. Further studies are needed to confirm these associations, namely between PTx and IVH, and to define the threshold from which PTx should be given with less harm effect. What is Known: • Platelet transfusions are given to preterm infants with thrombocytopenia either to treat bleeding or to prevent hemorrhage. • Lack of consensual criteria for transfusion. What is New: • A significant association between platelet transfusions and mortality, sepsis, and NEC.
