Background Changes in Doppler flow patterns of hepatic veins (HV), portal vein (PV) and intra-renal veins (RV) reflect right atrial pressure and venous congestion; the feasibility of obtaining these assessments and the clinical relevance of the findings is unknown in a general ICU population. This study compares the morphology of HV, PV and RV waveform abnormalities in prediction of major adverse kidney events at 30 days (MAKE30) in critically ill patients. Study design and methods We conducted a prospective observational study enrolling adult patients within 24 h of admission to the ICU. Patients underwent an ultrasound evaluation of the HV, PV and RV. We compared the rate of MAKE-30 events in patients with and without venous flow abnormalities in the hepatic, portal and intra-renal veins. The HV was considered abnormal if S to D wave reversal was present. The PV was considered abnormal if the portal pulsatility index (PPI) was greater than 30%. We also examined PPI as a continuous variable to assess whether small changes in portal vein flow was a clinically important marker of venous congestion. Results From January 2019 to June 2019, we enrolled 114 patients. HV abnormalities demonstrate an odds ratio of 4.0 (95% CI 1.4–11.2). PV as a dichotomous outcome is associated with an increased odds ratio of MAKE-30 but fails to reach statistical significance (OR 2.3 95% CI 0.87–5.96), but when examined as a continuous variable it demonstrates an odds ratio of 1.03 (95% CI 1.00–1.06). RV Doppler flow abnormalities are not associated with an increase in the rate of MAKE-30 Interpretation Obtaining hepatic, portal and renal venous Doppler assessments in critically ill ICU patients are feasible. Abnormalities in hepatic and portal venous Doppler are associated with an increase in MAKE-30. Further research is needed to determine if venous Doppler assessments can be useful measures in assessing right-sided venous congestion in critically ill patients.
Percutaneous microwave ablation is safe and effective in the treatment of large HCC tumors. Patients' survival and local tumor control were acceptable.
Rationale: Increasingly, patients are surviving acute respiratory failure (ARF), prompting the need to better understand standardized outcome measures commonly used during ARF follow-up studies. Objectives: Investigate standardized outcome measures (patientreported physical and mental health measures, and cognitive testing) compared with findings from semistructured, qualitative interviews. Methods: As part of two ARF multicenter follow-up studies, standardized outcome measures were obtained, followed by qualitative evaluation via an in-depth, semistructured interview conducted and coded by two independent researchers. Qualitative interviews revealed the following post-ARF survivorship themes: physical impairment; anxiety, depression, and post-traumatic stress disorder symptoms; and cognitive impairment. Scores from standardized measures related to these themes were compared for ARF survivors reporting versus not reporting these themes in their qualitative interviews. Results: Of 59 invited ARF survivors, 48 (81%) completed both standardized outcome measures and qualitative interviews. Participants' median (interquartile range) age was 53 (43-64) years; 54% were female, and 88% were living independently before hospitalization. The two independent reviewers classifying the presence or absence of themes from the qualitative interviews had excellent agreement (k = 0.80). There were significantly worse scores on standardized outcome measures for survivors reporting (vs. not reporting) physical and mental health impairments in their qualitative interviews. However, standardized cognitive test scores did not differ between patients reporting versus not reporting cognitive impairments in their qualitative interviews. Conclusions: These findings support the use of recommended, commonly used standardized outcome measures for physical and mental health impairments in ARF survivorship research. However, caution is needed in interpreting self-reported cognitive function compared with standardized cognitive testing.
Hepatitis C virus (HCV) is highly prevalent in Egypt. This work aimed at determining the seroprevalence of HCV among Cairo University students. The present study included 3,000 students from Cairo University, Egypt. Blood sample was obtained from each participant to be tested for HCV seromarker. HCV RNA detection by polymerase chain reaction (PCR) was carried out for those with positive anti-HCV. Overall prevalence rate of HCV antibody (anti-HCV) was 4.6%. It showed that the prevalence was relatively higher among females (86/1660; 5.2%) while males (51/1340; 3.8%) with no significant difference. PCR for HCV RNA was detected in 31.4% of the HCV antibody positive subjects (43/137). Which showed statistical significant difference between males (29/51) and females (14/86) at P = 0.001. Despite the prevalence rate reported in the present study was similar to anti-HCV prevalence among persons in the same age group, confirmed that HCV infection is detected among Cairo University students.

Evaluation of liver fibrosis stage is crucial in the assessment of chronic HCV patients, regarding decision to start treatment and during follow-up. Our aim was to assess the validity of the enhanced liver fibrosis (ELF) score in discrimination of advanced stage of liver fibrosis in naïve chronic HCV patients. We prospectively evaluated liver fibrosis stage in one hundred eighty-one naïve chronic HCV Egyptian patients by transient elastography (TE)-FibroScan. Patients were categorized into mild to moderate fibrosis (≤F2) group and advanced fibrosis (≥F3) group. The ELF score components, hyaluronic acid (HA), amino-terminal propeptide of type-III-procollagen (PIIINP) and tissue inhibitor of metalloproteinase type-1 (TIMP-1), were done using ELISA test. The mean values of ELF and its individual components significantly correlated with the hepatic fibrosis stage as measured by TE-FibroScan (P value 0.001). ELF cutoff value of 9.8 generated a sensitivity of 77.8%, specificity of 67.1%, area under the receiver operator characteristic curve (AUROC) of 0.76 with 95% confidence interval [CI] (0.68-0.83) for detecting advanced fibrosis (F ≥ 3). ELF panel is a good, reliable noninvasive test and showed comparable results to TE-FibroScan in detecting liver fibrosis stage in treatment naïve chronic HCV patients.
It is well known that hepatocellular carcinoma (HCC) develops as a consequence of hepatic fibrosis progression. In this study, we aimed to evaluate the inflammatory and fibrosis markers as predictors for HCC development among patients with hepatitis C virus (HCV) related chronic liver disease to help in early diagnosis and management of HCC. A total of 280 patients with chronic liver disease were included in this retrospective study, out of them 140 had liver cirrhosis with HCC and 140 had cirrhosis without HCC. Eight readily available blood indices King score, Fibro Q, AST-ALT ratio (AAR), APRI, LOK index, Goteborg University Cirrhosis Index (GUCI), fibro alpha, and Biotechnology Research Center (BRC) were constructed to compare the accuracies of these non invasive scores in predicting HCC development. All fibrosis scores except APRI were significantly higher in HCC. We found that Fibro alpha and BRC had superior diagnostic performance in prediction of HCC based on area under curve of 0.91 and 0.93, respectively compared to other scores with area under curve ranged from poor to failure (0.59-0.66). Almost all cirrhotic cases were secondary to HCV (93.6%), while HBV was detected in 2.1% of cases only. Anti-HCV positive was reported in 100% of HCC cases (P = 0.002). Fibro alpha and BRC scores can be used for prediction of HCC. J. Med. Virol. 89:1062-1068, 2017. © 2016 Wiley Periodicals, Inc.
BackgroundHepatitis C virus is a worldwide problem. Noninvasive methods for liver fibrosis assessment as ultrasound-based approaches have emerged to replace liver biopsy. The aim of this study was to evaluate the diagnostic accuracy of real-time elastography (RTE) in the assessment of liver fibrosis in patients with chronic hepatitis C (CHC), compared with transient elastography and liver biopsy.MethodsRTE, FibroScan and liver biopsy were performed in 50 CHC patients. In addition, aspartate aminotransferase to platelet ratio index (APRI) and routine laboratory values were included in the analysis.ResultsRTE was able to diagnose significant hepatic fibrosis (F ≥2) according to METAVIR scoring system at cut-off value of 2.49 with sensitivity 100%, specificity 66%, and area under the receiver-operating characteristics (AUROC) 0.8. FibroScan was able to predict significant fibrosis at cut-off value 7.5 KPa with sensitivity 88%, specificity 100%, and AUROC 0.94.APRI was able to predict significant hepatic fibrosis (F ≥2) with sensitivity 54%, specificity 80%, and AUROC 0.69. There was a significant positive correlation between the FibroScan score and RTE score (r=0.6, P=0.001).ConclusionsAlthough FibroScan is superior in determining significant hepatic fibrosis, our data suggest that RTE may be a useful and promising noninvasive method for liver fibrosis assessment in CHC patients especially in cases with technical limitations for FibroScan.
