Serum infrared spectral profile is predictive of the degree of hepatic fibrosis in chronic hepatitis C patients.

Assessment of liver fibrosis is crucial to guide the therapeutic strategy in patients with chronic liver disease. We investigated the potential of serum Fourier transform infrared (FTIR) spectroscopy for assessing the degree of hepatic fibrosis in patients with chronic hepatitis C (CHC). The study was conducted on dried serum samples from 94 CHC patients at different histological stages of hepatic fibrosis: METAVIR F0 (n = 20), F1 (n = 17), F2 (n = 20), F3 (n = 20) and F4 (n = 17).

Longitudinal Study of Cirrhosis Development in STAM and carbon tetrachloride Mouse Models Using Fourier Transform Infrared Spectral Imaging.

Animal models of cirrhosis are of great interest to investigate the pathological process leading to the final stage of cirrhosis. The aim of this study was to analyze the different steps involved in the progressive development of cirrhosis using Fourier transform infrared spectral histology in 2 mouse models of cirrhosis, the STAM model of metabolic cirrhosis, and the carbon tetrachloride-induced cirrhosis model. Formalin-fixed, paraffin-embedded liver samples were obtained from 3 mice at 5 time points in each model to analyze the course of hepatic lesions up to the formation of cirrhosis.

Anterior Versus Classical Approach During Right Hepatectomy for Hepatocellular Carcinoma: Inverse Propensity Score Weighted Analysis.

Background: Eastern data highlight the oncological benefits of the anterior approach (AA) during right hepatectomy (RH) for hepatocellular carcinoma (HCC). However, to our knowledge, previous western data on this topic are scarce. In this study, the oncological outcomes of AA and classical approach (CA) during RH for HCC were compared.

Alveolar echinococcosis in solid organ transplant recipients: a case series from two national cohorts.

Alveolar echinococcosis (AE) is a severe parasitic infection caused by the ingestion of Echinococcus multilocularis eggs. While higher incidence and faster evolution have been reported in immunosuppressed patients, no studies have been performed specifically on AE in transplant patients. We searched for all de novo AE cases diagnosed between January 2008 and August 2018 in solid organ transplant (SOT) recipients included in the Swiss Transplant Cohort Study and the FrancEchino Registry.

Hepatotoxicity of metronidazole in Cockayne syndrome: A clinical report.

Cockayne syndrome (CS) is a rare autosomal recessive genetic disorder characterized by growth failure and progressive multisystem dysfunction caused by deficient nucleotide excision repair. Whereas metronidazole (MTZ) hepatotoxicity is quite rare in the general population, cases of severe hepatic reaction to MTZ have been reported in CS patients. We report here the case of a 21-year-old CS patient who presented with jaundice following one week of treatment with MTZ combined with spiramycin for dental care.

White bile in patients with malignant biliary obstruction is an independent factor of poor survival.

Real-world studies are important to confirm effectiveness and safety in clinical practice, particularly in vulnerable populations.

Interference of hemolysis, hyperlipidemia, and icterus on plasma infrared spectral profile.

Recently, pre-analytical, analytical, and post-analytical issues have been addressed to implement biofluid FTIR spectroscopy as a novel diagnostic tool in the clinical setting. Although hemolysis, icterus, and hyperlipidemia are known to interfere with colorimetric and turbidimetric biochemical methods, there are no data on their impact on serum/plasma FTIR spectra. This study aimed at investigating the impact of hemoglobin, bilirubin, and triglycerides concentrations on plasma spectral analysis.

Investigating pre-analytical requirements for serum and plasma based infrared spectro-diagnostic.

Infrared spectroscopy is a rapid, easy-to-operate, label-free and therefore cost-effective technique. Many studies performed on biofluids (eg, serum, plasma, urine, sputum, bile and cerebrospinal fluid) have demonstrated its promising application as a clinical diagnostic tool. Given all these characteristics, infrared spectroscopy appears to be an ideal candidate to be implemented into the clinics.

[General practitioner density is not associated with survival in patients with hepatocellular carcinoma].

Objective: To determine if the density of general practitioners (GPs) had an impact on overall survival of patients with hepatocellular carcinoma (HCC) and stage of HCC at initial diagnosis in a North-Eastern region of France.

Methods: This retrospective study was performed with 246 consecutive HCC patients referred to a multidisciplinary meeting dedicated to hepatobiliary tumors in the Reims University Hospital from 2012 to 2016. The following data were collected: clinico-biological and radiological data, GP density in patient residence area, stage of HCC at diagnosis, treatment.

Dietary components modulate the risk of hepatocellular carcinoma in cirrhotic patients.

Eighty percent of hepatocellular carcinoma (HCC) cases occur after cirrhosis from various etiologies. The association between diet and cancer is well accepted, but the links with cirrhosis progression and HCC risk have been poorly investigated. However, we hypothesized that diet could be a modifiable preventive factor for HCC.

Hepatocellular carcinoma: CT texture analysis as a predictor of survival after surgical resection.

Objectives: To determine whether image texture parameters analysed on pre-operative contrast-enhanced computed tomography (CT) can predict overall survival and recurrence-free survival in patients with hepatocellular carcinoma (HCC) treated by surgical resection.

Methods: We retrospectively included all patients operated for HCC who had liver contrast-enhanced CT within 3 months prior to treatment in our centre between 2010 and 2015. The following texture parameters were evaluated on late-arterial and portal-venous phases: mean grey-level, standard deviation, kurtosis, skewness and entropy.

Results: There was no significant association between visceral obesity and MVI (OR = 1.

Biofluid infrared spectro-diagnostics: pre-analytical considerations for clinical applications.

Several proof-of-concept studies on the vibrational spectroscopy of biofluids have demonstrated that the methodology has promising potential as a clinical diagnostic tool. However, these studies also show that there is a lack of a standardised protocol in sample handling and preparation prior to spectroscopic analysis. One of the most important sources of analytical errors is the pre-analytical phase.
