Mean platelet volume and serum uric acid in neonatal sepsis: A case-control study

Background: Neonatal sepsis is the third leading cause of neonatal mortality after prematurity and intrapartum related complications worldwide. The literature regarding the use of Mean platelet volume as a diagnostic tool in neonatal sepsis is scanty.Methods: Prospective case control study in a district hospital. Neonates > 30 weeks gestation admitted to NICU during the study period were included. Neonates who did not have any risk factors for sepsis and did not have a positive blood culture or elevated CRP were categorized as group 1. Neonates who were admitted with risk factors of sepsis but did not have a positive CRP or blood culture positivity were categorized as group 2. Neonates who were admitted as probable sepsis and subsequently developed blood culture or CRP positivity were categorized as group 3.Septic workup was done for all the subjects at admission and at 72 hours after admission. Newborn with congenital anomalies and who were already on antibiotics prior to admission were excluded from the study. Statistical analysis was done using Statistical Package of Social Sciences (SPSS) version 20.0.Results: Total 240 Neonates were included in the study. Elevation of MPV in neonates with sepsis was seen as early as the first sample whereas CRP elevation was seen only on Day 3. Cut off value for Mean Platelet Volume (MPV) was found to be 10.15fl with sensitivity of 84% and specificity of 74%.Conclusions: MPV can be used as a earliest diagnostic marker for prediction of neonatal sepsis and mortality. It can facilitate early initiation of treatment without any additional exposure.

Introduction Preeclampsia is the most serious health risk during pregnancy for both the mother and the fetus. Even though platelet parameters are among the proposed biomarkers for the prediction of preeclampsia, the use of its indices in the diagnosis of preeclampsia is not increasing in Ethiopia. There is little information on platelet patterns in preeclampsia and normal pregnancy. The purpose of this study was to determine the pattern of platelet indices in women with preeclampsia in our study setting. Methods A case-control study was conducted among 180 pregnant women who attended anti-natal follow-ups from January 1 to April 3, 2019. An Ethylene Diamine Tetra Acetic Acid anti-coagulated venous blood was collected and analyzed using a hematology analyzer (MINDRAY®-BC-300Plus, Shenzhen China). The SPSS software version 26 was used to run the Mann Whitney U test, Kruskal-Wallis H test, and Kolmogorov-Smirnov normality test, Post-hock test augmented with Benforeni, receiver operating characteristics curve, and Spear Man rank-order correlation. A P-value of <0.05 was considered statistically significant. Results A total of 180 pregnant women were included in the study. Platelet count and platelet crit levels tend to decrease as pre-eclampsia becomes more severe. In contrast, the mean platelet volume and platelet distribution widths were significantly increased with the severity of preeclampsia (P<0.001). Platelet distribution width (rho = 0.731, p<0.001) and mean platelet volume (rho = 0.674, p<0.001) had statistically significant positive relationships with mean arterial pressure. The best metric for predicting preeclampsia was platelet distribution width (AUC = 0.986; 95%CI; 0.970, 1). Conclusions Platelet indices, including platelet count, mean platelet volume, platelet distribution width, and Platelet crit, have been identified as promising candidate markers for predicting preeclampsia in pregnant women. In the future, a serial examination of these indicators during several trimesters of pregnancy should be conducted.
