ABSTRACT
The study was carried out to determine the role of plasma fibrinogen in diagnosis of neonatal sepsis and to evaluate its role in predicting short term outcome. Sixty five neonates with clinical features suggestive of neonatal sepsis were included in this study. Seventy five neonates served as the control group. Plasma fibrinogen, prothrombin time, activated partial thromboplastin time and platelet counts were performed in all the neonates. Cut-off value of plasma fibrinogen for diagnosis of neonatal sepsis was determined with the help of receiver operating characteristic curve. Plasma fibrinogen level was found to be significantly higher among neonates with sepsis when compared to neonates in control group (p < 0.0001). It had sensitivity of 70.8 %, specificity of 82.7 %, positive predictive value (PPV) of 72.3 % and negative predictive value (NPV) of 81.6 % for diagnosis of neonatal sepsis at cut-off value of 301.90 mg/dL. When neonates with septic shock and/or disseminated intravascular coagulation (DIC) were excluded from study population, sensitivity and NPV rose to 91.9 % and 95.4 % at the same cut-off value while specificity and PPV remained the same. Lower level of plasma fibrinogen was detected in neonates with septic shock and/or DIC (p < 0.0001) and in neonates who died (p < 0.0001). Hence plasma fibrinogen can serve as an effective tool in diagnostic work up of neonatal sepsis as well as in assessing development of complications and outcome.
ABSTRACT
Unusual rise of acute encephalitis syndrome cases (AES) were reported in July 2014 in the northern region of West Bengal, India. Investigations were carried out to characterize the outbreak and to identify the associated virus etiology. This observational study is based on 398 line listed AES cases, mostly (70.8%, 282/398) adults, with case fatality ratio of 28.9% (115/398). Japanese encephalitis virus infection was detected in 134 (49.4%) among 271 AES cases tested and most of them (79.1%, 106/134) were adults. The study reports a large outbreak of genotype III Japanese encephalitis among adults in northern region of West Bengal, India. J. Med. Virol. 88:2004-2011, 2016. © 2016 Wiley Periodicals, Inc.
