adrenomedullin and Neonatal-Sepsis

The association of proadrenomedullin and neonatal sepsis has been examined in numerous studies. The object of our meta-analysis is to evaluate differences in proadrenomedullin among neonates with sepsis and health neonates. We systematically searched the following databases: MEDLINE, Clinicaltrials.gov, Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar, and WHO (International Clinical Trials Register Platform) using a structured algorithm. Statistical analysis was conducted using Revman 5.3 and R software. Included studies in the meta-analysis were assessed using the Newcastle-Ottawa scale. Proadrenomedullin levels were found significantly higher in neonates with sepsis than healthy neonates with an SMD equal with 3.07 [95% CI 1.71, 4.42 (p < 10

Early onset bacterial sepsis in neonates (EOS) is recognized as an important health condition. Early diagnosis is crucial. However, blood culture results are released in 48-72 hours. Many biomarkers have been investigated but none have been accepted as the gold standard. This study aimed to investigate the diagnostic value of the molecules: soluble form of triggering receptor expressed on myeloid cells-1 (sTREM-1), pentraxin-3 (PTX-3) and pro adrenomedullin (pro-ADM) in EOS and compare with currently used biomarkers.. In this multicenter prospective study, patients were enrolled from different NICUs around the Turkey. Patient data were collected via web-based registry system from attending centers. Neonates, hospitalized with a suspicion of EOS were enrolled. Blood culture and routine blood tests were collected and a serum sample was obtained and kept in - 80°C for studying the molecules. According to laboratory results, patients were divided into three groups as; proven sepsis, clinical sepsis and control group. Groups were compared in terms of demographic, clinical and laboratory findings. The primary outcome of the study was to assess any difference between groups in terms of the diagnostic value of the markers aforementioned.. A total of 130 patients were enrolled; proven sepsis (n = 36), clinical sepsis (n = 53) and control (n = 41) groups. Groups were similar in terms of demographic findings; mean WBC (P = 0.445), procalcitonin (PCT) (P = 0.083) and IL-6 (P = 0.814) levels. Mean C-reactive protein (CRP) level was significantly higher in clinical sepsis and proven sepsis groups compared to control group (P < 0.001). Mean PTX-3 (P = 0.547), pro-ADM (P = 0.766) and sTREM-1 (P = 0.838) levels were similar between groups.. These promising molecules failed to help in early diagnosis of EOS. Their relation to correlation with disease progression may make more sense as they seem to be expressed in higher amounts with the progression of the disease in previous studies. CRP was the most frequently used biomarker for detecting the sepsis in our study population.
