Factor V Leiden and Prothrombin Gene 20210A Variant in Neonatal Thromboembolism and in Healthy Neonates and Adults: A Study in a Single Center

This study was conducted to identify the prevalence of FV1691A and PT20210A mutations in neonates with symptomatic thromboembolism and in healthy neonates and adults. A review of 137 healthy neonates, 368 healthy adults, and 9 neonates with clinical thrombosis was done to investigate for hereditary prothrombotic mutations. For the neonates with thromboembolism, data were collected to reveal the underlying diagnosis, site of thrombosis, and associated risk factors. Investigations included screening for factor V 1691A and prothrombin 20210A. Seven of 9 neonates had one or more risk factors at the time of thromboembolism. Seventy percent (5/7) had underlying congenital thrombophilia (4/7 FV Leiden, 1/7 homozygote protein C deficiency). Among the healthy population, 11.9% of the neonates and 9% of the adults had FV1691A mutation, 4.8% of the neonates and 2.7% of the adults had PT 20210A mutation. Incidence of FV1691A mutation in the neonates with symptomatic thromboembolism was very high. The prevalence of both FV1691A and PT20210A mutations were remarkably higher than previously reported.

Does early erythropoietin therapy decrease transfusions in anemia of prematurity

Objective. To investigate the effect of early erythropoietin treatment on induction of erythropoiesis and the need for transfusion in Very Low Birth Weight (VLBW) infants with acute neonatal problems.Methods. The study group consisted of 14 VLBW prematures with gestational ages less than 32 weeks who were given subcutaneous erythropoietin (600 U/kg per week) and oral iron (3 mg/kg per day) during the first 7–8 weeks of their life, while 13 other VLBW prematures that were given placebo constituted the control group. Weekly hemotocrit, (Hct) reticulocyte (Ret) values and the volume of blood drawn and transfused were recorded in the both groups.Results. The groups were comparable regarding with birth weights and gestational ages. The volume of the blood drawn (76.8 ± 42.5 and 37.0 ± 15.2) was higher and the volume of the transfusions (51.84 ± 49.30 and 68.84 ± 41.2) was lower in the study group but the differences between the groups were not significant (p>0.05). The hemotocrit, the reticulocyte and the ferritin values were similar in both the groups at the end of the therapy.Conclusion. Under the neonatal intensive care circumstances of developing countries where blood volumes needed for laboratory analysis are still very high, phlebotomy losses can not be avoided. Thus early erythropoietin and iron therapy at these doses are not effective in decreasing the need for transfusion and induction of endogenous erythropoiesis.

Multi-resistant viridans streptococcal pneumonia and sepsis in the ventilated newborn

Abstract Mechanical ventilation increases the frequency of nosocomial infections. This study describes the frequency of multi-resistant viridans streptococcal colonisation, the clinical course of nosocomial sepsis and ventilator-associated pneumonia in mechanically ventilated neonates in the neonatal intensive care unit of Ankara University Hospital. Seventy-nine ventilated newborns were enrolled. Broncho-alveolar lavage culture and blood cultures were positive in 44 (56%) and 17 (22%) patients, respectively. The most predominant micro-organisms in broncho-alveolar lavage cultures were multi-resistant viridans streptococci (29, 66%). Viridans streptococci were also one of the predominant organisms in blood cultures (5/17, 29%). In 29 patients with broncho-alveolar lavage positive for viridans streptococci, nine (31%) had colonisation, 15 (52%) had ventilator-associated pneumonia and five (17%) had sepsis owing to viridans streptococcus. Ventilator-associated pneumonia was encountered in 52/1000 ventilation days. Mortality was caused by infection in three (10%) of them. Mechanically ventilated neonates in our neonatal intensive care unit had a high rate of both multi-resistant viridans streptococcus airway colonisation and subsequent ventilator-associated pneumonia and sepsis.
