Background: Intraventricular hemorrhage (IVH) is an important cause of death in premature infants. This study aimed to assess the association of the umbilical cord plasma levels of interleukin-6 (IL-6) and erythropoietin (EPO) with the occurrence and severity of IVH in premature infants.Methods: Fifty premature newborns of mothers with chorioamnionitis risk factor were selected via nonprobability sampling. The concentration of the cord plasma's IL-6 and erythropoietin were measured by enzyme-linked immunosorbent assay (ELISA) for 3 days. Finally, all samples underwent sonography for the diagnosis of IVH. Results analyzed statistically.Results: Among the samples, 68.98% of them were diagnosed with IVH grade 1. The most severe IVH cases were detected on the second day. The mean and standard deviation of IL-6 level was 74.71 ± 50.53 in the case group and 24.10 ± 46.10 in the control group. There was a correlation between IL-6 levels and IVH (p = 0.0005). The mean and standard deviation of EPO level was 18.38 ± 15.23 in the IVH group and 6.45 ± 13.48 in samples without IVH. A correlation was detected between EPO level and IVH (p = 0.005).Conclusion: The concentration of IL-6 and EPO levels of the cord plasma was higher in the premature newborns with IVH.

Background: Cerebrospinal Fluid (CSF) culture for distinction between aseptic and bacterial meningitis can be difficult and long-term, and other diagnostic methods are under studying. This study aimed to assess the diagnostic value for the levels of Interleukin 1 (IL-1), IL-6 and IL-8 of CSF in the children and adolescent with meningitis. Methods: Fifty-one patient with meningitis between one month and 18 year included in a Cross-Sectional Studies in the Rasul Hospital, Tehran, from 2012 to 2014. All of samples underwent aspiration of CSF. The routine tests performed that include culture; coloring and biochemical of CSF. The concentrations of IL-1, IL-6 and IL-8 were determined by Enzyme-linked immunosorbant assay (ELISA) method and all of data were analyzed. Results: Frequency of bacterial and aseptic meningitis was equal (49%). 64.7% of samples were boys and gender had not different between two bacterial and aseptic group (P=0.7). Mean (±SD) of the age in total was 358.46±858.40, and bacterial group had a higher mean of age than aseptic group (P=0.047). The level of IL-1 was 10.87±37.04 pg/ml in bacterial and 0.55±1.64 pg/ml in aseptic group, that had not different (P=0.168). The level of IL-6 was 90.51±139.3 pg/ml in bacterial and 21.36±67.84 pg/ml in aseptic group, that had significant different (P=0.030). The level of IL-8 was 365.40±765.52 pg/ml in bacterial and 50.66±59.34 pg/ml in aseptic group, that had significant different (P=0.047). Diagnostic value of IL-1 was noted in the 80.77% of bacterial and 68.00% of aseptic group that had not different (P=0.349). Diagnostic value of IL-6 was noted in the 53.85% of bacterial and 64.00% of aseptic group that had not different (P=0.572). Diagnostic value of IL-8 was noted in the 80.77% of bacterial and 28.00% of aseptic group that had significant different (P=0.000). There was not different between two group of CSF variables include coloring degree, WBC and RBC index, glucose and protein. Conclusion: Although the concentration of IL-6 and IL-8 was higher in bacterial meningitis than in aseptic patients, only IL-8 had suitable diagnostic value for distinction between different types of meningitis.
