Diagnosis Criteria

Sepsis is a public health problem in many countries. The latest diagnosis criteria are quick Sequential Organ Failure Assessment  (qSOFA). Procalcitonin (PCT) could be used to aid the diagnosis of sepsis. The aim of this study was to determine the diagnostic value of PCT between CLIA and quantitative immunochromatography tests in sepsis patients. Samples were obtained from the resuscitation room, intensive observation room, and Intensive Care Unit (ICU) Dr. Soetomo General Hospital between December 2017-February 2018. One hundred and one subjects were examined and classified into sepsis group (n=71) and healthy group (n=30), based on qSOFA and SIRS criteria. Procalcitonin test with CLIA and quantitative immunochromatography method were performed in all subjects, followed by culture examination in sepsis group using PhoenixTM 100. The diagnostic value of the two methods was analyzed by 2x2 table with a Confidence Interval (CI) of 95%. There were significant differences of procalcitonin level between CLIA and quantitative immunochromatography method in the sepsis group (p=0.009) and in the healthy group (p=0.002). The diagnostic value of procalcitonin level by CLIA method with a cut-off value ≥ 0.27 ng/mL (AUC=0.839, sensitivity (Sn)=74.6%, specificity (Sp)=86.7%, Positive Predictive Value (PPV)=93%, Negative Predictive Value (NPV)=59.1%) had the same sensitivity but higher specificity, PPV, and NPV rather than by quantitative immunochromatography method (AUC=0.786, Sn=74.6%, Sp=66.7%, PPV=84.1%, NPV=52.6%). Procalcitonin examination with CLIA had a better diagnostic value than quantitative immuno-chromatography method.

Background. This study aims to evaluate the diagnostic value of nuclear-enriched abundant transcript 1 (NEAT1) expression in peripheral blood mononuclear cells (PBMCs) for the early diagnosis of sepsis. Methods. A total of 59 patients with sepsis, 52 noninfectious SIRS patients, and 56 healthy controls were recruited fort this study. The levels of NEAT1 expression in PBMCs were measured using quantitative real-time polymerase chain reaction (qRT-PCR). Results. Compared with healthy controls, NEAT1 expression of PBMCs in sepsis and SIRS groups were significantly increased (3.76 ± 0.71- and 1.64 ± 0.43-fold, resp.) (P<0.01), but NEAT1 levels are significantly lower in the SIRS group than in the sepsis group, and there was no statistical significant relevance between survivors and nonsurvivors in patients with sepsis. NEAT1 with an area under the curve (AUC) of 0.851 (95% CI: 0.812–0.935) indicated sensitivity (67.85%) and specificity (87.27%) for the diagnosis for sepsis, the positive predictive value (PPV) was 83.3%, and the negative predictive value (NPV) was 71.6%. The AUC for NEAT1 in the diagnosis of SIRS versus healthy controls was 0.755 (95% CI: 0.664–0.847), with 69.23% sensitivity and 70.91% specificity, the PPV was 72.3%, and the NPV was 72.49%. Conclusion. Measurement of NEAT1 expression in PBMCs could be considered as a good additive marker for the diagnosis of sepsis.

Objective Sepsis is a complex clinical condition caused by a dysregulated immune response to an infection resulting in a fatal outcome. This study aimed to investigate the value of urine soluble triggering receptor expressed on myeloid cells (sTREM-1) for diagnosing culture-proven sepsis in preterm infants. Methods Preterm neonates were evaluated for late-onset sepsis (LOS). Laboratory investigations were performed. Urine sTREM-1 samples and blood cultures were synchronously collected. Using blood culture results, preterm neonates were divided into the culture-proven group and suspected sepsis group. Results A total of preterm 62 infants were included in the study; 31 had culture-proven sepsis and 31 were suspected as having sepsis. There were no significant differences in gestational age, sex, birth weight, and delivery mode between the groups. Neonates in the culture-proven group had significantly higher urine sTREM-1 levels than did those in the suspected sepsis group. Using a cut-off point for a urine sTREM-1 level of 78.5 pg/mL, the sensitivity was 0.90, specificity was 0.78, positive predictive value was 0.68, and negative predictive value was 0.94. Conclusions The present study highlights the role of urine sTREM-1 levels in LOS. Urine sTREM-1 may be a reliable and sensitive marker in detecting sepsis in preterm infants.

Abstract Background There are many causes of pleural disease including variable benign and malignant etiologies. DWI is a non-enhanced functional MRI technique that allows qualitative and quantitative characterization of tissues based on their water molecules diffusivity. The aim of this study was to evaluate the diagnostic value of DWI-MRI in detection and characterization of pleural diseases and its capability in differentiating benign from malignant pleural lesions. Results Conventional MRI was able to discriminate benign from malignant lesions by using morphological features (contour and thickness) with sensitivity 89.29%, specificity 76%, positive predictive value 89%, negative predictive value 76.92%, and accuracy 85.37%. ADC value as a quantitative parameter of DWI found that ADC values of malignant pleural diseases were significantly lower than that of benign lesions (P < 0.001). Hence, we discovered that using ADC mean value of 1.68 × 10-3 mm2/s as a cutoff value can differentiate malignant from benign pleural diseases with sensitivity 89.3%, specificity 100%, positive predictive value 100%, negative predictive value 81.2%, and accuracy 92.68% (P < 0.001). Conclusion Although DWI-MRI is unable to differentiate between malignant and benign pleural effusion, its combined morphological and functional information provide valid non-invasive method to accurately characterize pleural soft tissue diseases differentiating benign from malignant lesions with higher specificity and accuracy than conventional MRI.

Clinical Consequences

The picture of chronic liver diseases (CLDs) has changed considerably in recent years. One of them is the increase of non-alcoholic fatty liver disease. More and more CLD patients, even those with liver cirrhosis (LC), tend to be presenting with obesity these days. The annual rate of muscle loss increases with worsening liver reserve, and thus LC patients are more likely to complicate with sarcopenia. LC is also characterized by protein-energy malnutrition (PEM). Since the PEM in LC can be invariable, the patients probably present with sarcopenic obesity (Sa-O), which involves both sarcopenia and obesity. Currently, there is no mention of Sa-O in the guidelines; however, the rapidly increasing prevalence and poorer clinical consequences of Sa-O are recognized as an important public health problem, and the diagnostic value of Sa-O is expected to increase in the future. Sa-O involves a complex interplay of physiological mechanisms, including increased inflammatory cytokines, oxidative stress, insulin resistance, hormonal disorders, and decline of physical activity. The pathogenesis of Sa-O in LC is diverse, with a lot of perturbations in the muscle–liver–adipose tissue axis. Here, we overview the current knowledge of Sa-O, especially focusing on LC.

This study aimed to investigate whether the incorporation of contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) into the international consensus guidelines (ICG) for the management of intraductal papillary mucinous neoplasm (IPMN) could improve its malignancy diagnostic value. In this single-center retrospective study, 109 patients diagnosed with IPMN who underwent preoperative CH-EUS between March 2010 and December 2018 were enrolled. We analyzed each malignancy diagnostic value (sensitivity (Se), specificity (Sp), positive predictive value (PPV), and negative predictive value (NPV)) by replacing fundamental B-mode EUS with CH-EUS as the recommended test for patients with worrisome features (WF) (the CH-EUS incorporation ICG) and comparing the results to those obtained using the 2017 ICG. The malignancy diagnostic values as per the 2017 ICG were 78.9%, 42.3%, 60.0%, and 64.7% for Se, Sp, PPV, and NPV, respectively. The CH-EUS incorporation ICG plan improved the malignancy diagnostic values (Se 78.9%/Sp, 53.8%/PPV, 65.2%/NPV 70.0%). CH-EUS may be useful in determining the appropriate treatment strategies for IPMN.

Background: Neonatal sepsis is a life-threatening condition with high mortality and morbidity throughout the world. Objective: This study evaluated the diagnostic role of serum procalcitonin (PCT), interleukin-6 (IL-6), tumor necrosis factor-a (TNF-a) and C-reactive protein (CRP) in the early diagnosis of neonatal sepsis. Methods: This cross-sectional study was conducted among neonates admitted to the special baby care unit (SCABU) of BIRDEM General Hospital, Dhaka, from November 2018 to April 2019. According to selection criteria, 90 clinically suspected cases of neonatal sepsis were selected and categorised into confirmed, probable, and no sepsis groups based on CRP, white cell count, platelet count, and blood culture results. Serum PCT, IL-6, and tumor  necrosis factor (TNF-a) were estimated in all cases by standard laboratory methods. Results: Serum PCT, IL-6, CRP, and TNF-awere significantly higher in confirmed and probable sepsis groups in comparison to no sepsis group. Among the studied biomarkers, serum PCT was found most sensitive (95% sensitivity), and serum IL-6 was found most specific biomarkers (65.7% specificity) than CRP and TNF-a for the diagnosis of neonatal septicaemia. Though the accuracy of both PCT and IL-6 was found equal (70%), but the positive predictive value (PPV) and negative predictive value (NPV) of serum PCT were higher than IL-6. Conclusion: Both serum PCT and IL-6 are more sensitive and specific markers than CRP and TNF-a in the diagnosis of neonatal sepsis. Moreover, serum PCT is more useful than IL-6.

Background and Study Aims: Portal hypertension is one of the most important complications of liver cirrhosis. The prevalence of varices among cirrhotic patients is variable. Therefore, endoscopic screening of all patients with liver cirrhosis would result in a large number of unnecessary additional burdens to endoscopic units. Our aim was to assess the diagnostic accuracy of spleen stiffness measured by transient elastography (Fibroscan) for prediction of the presence of varices in patients with hepatitis C related cirrhosis. Patients and Methods: The study was carried out on 100 patients with HCV-induced cirrhosis and were divided into 2 groups according to presence or absence of varices by Esophago-gastro-duodenoscopy: Group I: patients with HCV-induced cirrhosis with varices; Group II: patients with HCV-induced cirrhosis without varices. Clinical and laboratory parameters, andominal ultrasonography, Upper gastrointestinal endoscopy and transient elastography to assess the liver and spleen stiffness were carried out to all studied persons. Results: Spleen stiffness had significant diagnostic value to differentiate between cirrhotic patients with varices and cirrhotic patients without varices , it had significant diagnostic value in presence of esophageal varices at cut-off (≥46.4 K Pascal) the sensitivity for detection of esophageal varices was 93%, specificity 100%, positive predictive value (PPV) was 80%, negative predictive value (NPV) was 100%; accuracy was 95% and area under the curve was 0.98 denoting that spleen stiffness is a good predictor of esophageal varices. Conclusion: Spleen stiffness was considered as an excellent predictor of esophageal varices and better than liver stiffness in prediction of esophageal varices presence and had significant diagnostic value to differentiate between the patients with varices and patients without varices at cut off (≥46.4 K Pascal) and it may have a role in variceal grading.
