BACKGROUND Careful selection of hepatocellular carcinoma (HCC) patients prior to chemoembolization treatment is a daily reality, and is even more necessary with new available therapeutic options in HCC. AIM To propose two new models to better stratify patients and maximize clinical benefit: “6 and 12” and “pre/post-TACE-predict” (TACE, transarterial chemoembolization). METHODS We evaluated and compared their performance in predicting overall survival with other systems {Barcelona Clinic Liver Cancer (BCLC), Albumin-Bilirubin (ALBI) and NIACE [Number of tumor(s), Infiltrative HCC, alpha-fetoprotein, Child-Pugh (CP), and performance status]} in two HCC French cohorts of different stages enrolled between 2010 and 2018. RESULTS The cohorts included 324 patients classified as BCLC stages A/B (cohort 1) and 137 patients classified as BCLC stages B/C (cohort 2). The majority of the patients had cirrhosis with preserved liver function. “Pre-TACE-predict” and “6 and 12” models identified three distinct categories of patients exhibiting different prognosis in cohort 1. However, their prognostic value was no better than the BCLC system or NIACE score. Liver function based on CP and ALBI grades significantly impacted patient survival. Conversely, the “post-TACE-predict” model had a higher predictive value than other models. The stratification ability as well as predictive performance of these new models in an intermediate/advanced stage population was less efficient (cohort 2). CONCLUSION The newly proposed “Pre-TACE-predict” and “6 and 12” models offer an interesting stratification into three categories in a recommended TACE population, as they identify poor candidates, those with partial control and durable response. The models' contribution was reduced in a population with advanced stage HCCs.

Peroralcholangio-pancreatoscopy (POCP) is used for diagnosis and treatment of biliopancreatic disease when standard endoscopy (ERCP) or pre-operative imaging workup failed. We aimed to evaluate the diagnostic and therapeutic performance of POCP in complex biliary and pancreatic diseases.Patients with indeterminate biliary or pancreatic duct (PD) strictures, and patients with failure of complex biliary or pancreatic stones removal, were enrolled (six centers). The primary endpoint evaluated malignancy diagnostic performances (accuracy, sensitivity, specificity) and therapeutic performances (biliary or pancreatic stones extraction). Secondary endpoints evaluated: technical success in lesion visualization, ease of maneuvering, image quality and 30-days complications.From November 2016 to March 2018, 66 patients were included: 29/37 women/men, median age (IQR): 73 (64-82). Fifty-three patients had diagnostic POCP and 13 patients therapeutic POCP. One endoscopist with one or two endoscopy nurses performed 94% of the POCP. The 'POCP visual impression' of malignancy showed 92.0% sensitivity, 92.9 % specificity and 92.5 % overall accuracy compared with the final diagnosis. 'POCP-guided samples histological analysis' showed 75.0 % sensitivity and 91.6% specificity. The technical success for lesion visualization was 98.5%. The median VAS scores for insertions in bile and PD were respectively 9.0 (8.1-9.6) and 9.0 (8.8-10.0). Median VAS score for access to the lesion and image quality were respectively 9.0 (7.7-9.6) and 9.0 (7.9-9.7). Only three 30-day minor complications occurred without any major complications.POCP was an effective, safe and easy-to-use tool in routine clinical practice for the management of complex diagnostic and therapeutic biliary and pancreatic diseases (NCT03190343).

The “six-and-twelve” (6&12) score is a new hepatocellular carcinoma (HCC) prognostic index designed for recommended transarterial chemoembolization (TACE) candidates. Quick and easy to use by the sum of tumor size (cm) and number, this model identifies three groups with different survival time (the sum is ≤ 6; or > 6 but ≤ 12; or > 12); a survival benefit with TACE can be expected for HCC patients with a score not exceeding twelve. Recently, Wang ZW et al showed that the “6&12” model was the best system correlated with radiological response after the first TACE. Thus, we wanted to assess its survival prediction ability as well as its prognostic value and compared it to other systems (Barcelona Clinic Liver Cancer, Hong Kong Liver Cancer (HKLC) staging, Albumin-Bilirubin grade, tumor nodularity, infiltrative nature of the tumor, alpha-fetoprotein, Child-Pugh class, and Performance Status score, Cancer of the Liver Italian Program, Model to Estimate Survival for HCC scores, up-to-seven criteria) different from Wang ZW et al study in a multicenter French cohort of HCC including only recommended TACE candidates retrospectively enrolled. As previously demonstrated, we show that the "6&12” score can classify survival within this French cohort, with a prognostic value comparable to that of other systems, except HKLC staging. More importantly, the “6&12” score simplicity and ability in patients’ stratification outperform other systems for a routine clinical practice.

International audience; Background: During thyroid surgery, preservation of parathyroid gland (PG) feeding vessels is often impossible. The aim of the Fluogreen study was to determine the feasibility of using indocyanine green (ICG)-based intraoperative mapping angiograms of the PG (iMAP) to improve vascular preservation.Study design: This prospective study enrolled all patients undergoing thyroid lobectomy or total thyroidectomy at the Hôpital Européen Marseille between September and December 2018. After exploring the thyroid lobe by autofluorescence to locate the PGs, ICG solution was injected intravenously to locate the PG feeding vessels and guide dissection. A second ICG injection was administered at the end of the lobectomy to assess perfusion of the PGs. The primary outcome was the quality of the angiogram, scaled as iMAP 0 (not informative), iMAP 1 (general vascular pattern visible but no clear vascular pedicle flowing into the PG), or iMAP 2 (clear vascular pedicle flowing into the PG). The secondary outcome was the PG perfusion score at the end of surgery, scaled from ICG 0 (no perfusion) to ICG 2 (intense uptake).Results: A total of 47 adult patients were analyzed, including 34 total thyroidectomies and 13 lobectomies. ICG angiography assessed 76 PGs, which were scored as iMAP 2 in 24 cases (31.6%), iMAP 1 in 46 (60.5%) and iMAP 0 in six (7.9%). At the end of dissection, the ICG perfusion score was significantly better for the PGs with informative angiography (iMAP 1 or 2), than for the PGs with uninformative angiography (iMAP 0), or the PGs not evaluated by vascular angiography (p < 0.05).Conclusion: iMAP is feasible and provides direct vascular information in one-third of the cases. Further improvements to this technology are necessary, and the influence of this technique on patient outcomes during thyroidectomy will need to be further evaluated.

Aim To study if one of the two molecules could lead to a lower number of follow up visits and intra-vitreous injection (IVI) with the same efficacy. Methods ELU (or "elected" in French) study is a retrospective study conducted in real life in patients presenting suboptimal response after ranibizumab IVI (phase 1) and secondary switched to aflibercept (phase 2). The number of follow up visits and IVI were compared in both phases. Visual acuity (VA) evolution and "switching" reasons were secondary analyzed. Results We retrospectively included data of 33 patients (38 eyes) with age-related macular degeneration (AMD; mean age: 77±7.7y). The number of monthly follow up visits [median (Q1; Q3)]: was significantly lower with aflibercept (phase 2), respectively 1.0 (0.81; 1.49) visits in phase 1, versus 0.79 (0.67; 0.86) visits in phase 2. The median number of monthly IVI also significantly decreased in phase 2, respectively 0.67 (0.55; 0.90) IVI in phase 1, versus 0.55 (0.45; 0.67) IVI in phase 2. The mean VA evolution (VA final-VA initial) was similar in both phases, (P>0.05). Whatever the reason for "switching" (loss of efficacy, tachyphylaxis, tolerance problems), there was no incidence on VA evolution over the time. Conclusion Our results show that switching from ranibizumab to aflibercept in "suboptimal" patients significantly reduce the number of follow up visits and IVI, with a comparable efficacy. This decrease in visit number could improve patients' quality of life and reduce surgical risk by reducing the number of injections.

BACKGROUND Conventional transarterial chemoembolization (cTACE) with lipiodol is widely performed in patients with hepatocellular carcinoma (HCC) unsuitable for curative treatment. Additional tumor parameters such as HCC macroscopic appearance based on imaging might be helpful for transarterial chemoembolization prognostication and management. PATIENTS AND METHODS A total of 405 patients with HCC who underwent cTACE between 2008 and 2016 from a real-life multicenter French cohort were retrospectively reviewed. Tumors were classified into two macroscopic types according to HCC gross appearance on imaging: nodular versus non-nodular. The study population was stratified into two groups: derivation and validation cohorts. Independent prognostic factors of survival based on multivariate cox regression models were determined and then assessed in the validation set. Thereafter, time to progression (TTP) and radiological response rate were investigated for each prognostic factors of survival. RESULTS Median overall survival (OS) was 35 months for Barcelona Clinic Liver Cancer (BCLC) stage A, 22 months for BCLC stage B and 12 months for BCLC stage C patients (P < 0.0001). The corresponding TTP for these patients was 12 (7-17) months, 5 (3-6) months and 1.2 (1.2-3) months (P < 0.0001). Multivariate analysis revealed that tumors size and number, non-nodular type, alpha-fetoprotein, aspartate aminotransferase serum levels and impairment of performance status-1 were independent predictors of survival among the study groups. Non-nodular type was the most powerful factor that influences OS, TTP and radiological response rate for the recommended transarterial chemoembolization candidates. TTP was consistent with OS within each stage. CONCLUSION HCC macroscopic appearance on imaging is a determinant predictor of outcome after cTACE in a real-life multicenter cohort.

Background & aim We investigated the combination of rapid antigen detection (RAD) and RT-qPCR assays in a stepwise procedure to optimize the detection of COVID-19. Methods From August 2020 to November 2020, 43,399 patients were screened in our laboratory for COVID-19 diagnostic by RT-qPCR using nasopharyngeal swab. Overall, 4,691 of the 43,399 were found to be positive, and 200 were retrieved for RAD testing allowing comparison of diagnostic accuracy between RAD and RT-qPCR. Cycle threshold (Ct) and time from symptoms onset (TSO) were included as covariates. Results The overall sensitivity, specificity, PPV, NPV, LR-, and LR+ of RAD compared with RT-qPCR were 72% (95%CI 62%–81%), 99% (95% CI95%–100%), 99% (95%CI 93%–100%), and 78% (95%CI 70%–85%), 0.28 (95%CI 0.21–0.39), and 72 (95%CI 10–208) respectively. Sensitivity was higher for patients with Ct ≤ 25 regardless of TSO: TSO ≤ 4 days 92% (95%CI 75%–99%), TSO > 4 days 100% (95%CI 54%–100%), and asymptomatic 100% (95%CI 78–100%). Overall, combining RAD and RT-qPCR would allow reducing from only 4% the number of RT-qPCR needed. Conclusions This study highlights the risk of misdiagnosing COVID-19 in 28% of patients if RAD is used alone. A stepwise analysis that combines RAD and RT-qPCR would be an efficient screening procedure for COVID-19 detection and may facilitate the control of the outbreak.

BackgroundDiagnosing SARS CoV-2 infection with certainty is essential for appropriate case management. We investigated the combination of rapid antigen detection (RAD) and RT-qPCR assays in a stepwise procedure to optimize the detection of COVID-19.MethodsFrom August 2020 to November 2020, 43,399 patients were screened in our laboratory for COVID-19 diagnostic by RT-qPCR using nasopharyngeal swab.

Overall, combining RAD and RT-qPCR would allow reducing from only 4% the number of RT-qPCR needed.ConclusionThis study highlights the risk of misdiagnosing COVID-19 in 28% of patients if RAD is used alone. Thus, negative results from RAD needs to be confirmed by RT-qPCR prior to making treatment decisions. A stepwise analysis that combines RAD and RT-qPCR would be an efficient screening procedure for COVID-19 detection and may facilitate the control of the outbreak.

Background & aim Screening for genital infection (GI) such as bacterial vaginosis (BV) and yeast infection, for sexually transmitted infection (STI), and for asymptomatic carriage of group B streptococcus (GBS) in pregnant women are common reason for medical appointments. The diagnosis and control of GIs, STIs, and GBS are major issues, for fertility and overall well-being of affected women. Conventional testing is performed using vaginal/cervical classical sampling (VCS); this procedure requires pelvic examination performed by health care professionals which raises concerns among women. Vaginal-self-sampling (VSS), as an alternative to VCS, might capture more women. The aim was first to show non-inferiority of VSS compared with VCS to screen for GIs, STIs, and GBS; second to determine the feasibility of VSS. Methods VSS and VCS from 1027 women were collected by health care professionals and simultaneously carried out on each patient. GIs, STIs, and GBS were systematically screened in both paired VSS and VCS samples. Non-inferiority of VSS compared with VCS was assessed using z statistic for binomial proportions. Results Prevalence of GIs were 39.7% using VSS and 38.1% using VCS (p = 0.0016). Prevalence of STIs was 8.5% (VSS) vs 8.1% (VCS) (p = 0.0087). Prevalence of GBS was 13.4% (VSS) and 11.5% (VCS) (p = 0.0001). Most participants (84%) recommended the use of VSS. Conclusions This study shows that VSS was not inferior to VCS for the detection of GIs, STIs, and GBS. This study provides evidence that VSS can be used as a universal specimen for detection of lower genital tract infections in women. Study identification number ID-RCB 2014-A01250-4.

Background: Sorafenib is the first-line treatment for advanced hepatocellular carcinoma (HCC). The management of its side effects is improving. This study aimed to assess, in real life, if this translates into a better prognosis. Methods: This was a retrospective study of advanced HCC patients treated with sorafenib between 2007 and 2017. Results: 188 advanced HCC patients received > 4 weeks of sorafenib. Median treatment duration was 5.4 months and median overall survival (mOS) 10 months (95% confidence interval 15–27). Sorafenib was initiated in 65 patients in 2007–2012 and 123 in 2013–2017. Both groups were comparable except for Barcelona Clinic liver cancer class. Tumor progression, disease control (DC) rate, and incidence of toxicity were similar in the 2 periods, but the duration of treatment (4.3 vs. 5.9 months; p < 0.01) and mOS (8 vs. 12 months; p < 0.002) differed. Among progressive disease patients, mOS was similar (7 months) but for those who had DC at 8 weeks, mOS was longer in the recent period (13 vs. 27 months; p < 0.0001). In the univariate analysis of OS, the period of treatment had a prognostic value. Conclusion: When comparing 2 periods of treatment in advanced HCC patients under sorafenib, duration of treatment and mOS were higher in the recent period. While mOS did not differ for patients who progressed, it was 2-fold higher in the recent period for those who had tumor control. Improvements in the use of sorafenib seem to be associated with better outcomes limited to patients with DC.

BACKGROUND Direct-acting antivirals (DAAs) therapy against hepatitis C viral (HCV) infection has markedly improved the sustained viral response. However, recent studies have suggested an unsuspected high rate of hepatocellular carcinoma (HCC) recurrence. PATIENTS AND METHODS A retrospective case-control study was carried out to investigate the impact of DAAs on tumor recurrence in patients with complete response to HCC treatment within our HCV-related cirrhosis cohort. Patients who received [group 1 (G1), n=22] or not [group 2 (G2), n=49] a DAAs therapy were matched 1 : 2 for age, sex, liver function, HCC stage, and treatment. RESULTS Initial HCC were mostly Barcelona Clinic Liver Cancer stage A (95% G1, 94% G2). Sustained viral response with DAAs was achieved in 86% of patients. After a similar median overall follow-up time with similar radiologic surveillance after HCC treatment, 41% of patients developed radiologic tumor recurrence in G1 versus 35% of patients in G2 (P=0.7904). There was no significant difference in time to progression between the two groups [12 (9-16) months G1 vs. 14 (8-21) months G2, P=0.7688], or Barcelona Clinic Liver Cancer stage at recurrence. However, the interval between HCC treatment and antiviral therapy was significantly different among DAAs patients with recurrence and those without recurrence [7.0 (2.5-9.0) months vs. 36.0 (9.0-58.0) months, P=0.0235, respectively]. CONCLUSION In our case-control study, HCV therapy with DAAs does not accelerate or prevent early HCC recurrence compared with untreated patients. The rate of recurrence, time to progression, and HCC pattern are similar. Early DAAs treatment (

Background Peripheral nerve system (PNS) involvement is common in Fabry's disease (FD), predominantly affecting the small nerve fibers that are difficult to investigate with conventional electrophysiological methods. Patients and methods Eighteen patients followed for Fabry's disease underwent a prospective series of electroneurophysiological explorations, including a study of the cardiac parasympathetic autonomic nervous system (ANS) and electrochemical skin conductance (ESC) tests. Data were compared with those obtained in 18 matched healthy controls. Results All patients had at least one clinical sign suggestive of neuropathy: 16 reported an acrosyndrome and 12 had dyshidrosis. Cold hypoesthesia was found in 15 patients and heat hypoesthesia in 13. Electroneurophysiological investigations and study of the cardiac parasympathetic ANS were normal in all patients. The ESC was significantly lower in FD patients compared with controls. Conclusion PNS involvement is common in FD and should be suspected in patients exhibiting an acrosyndrome, dyshidrosis and/or cold hypoesthesia. Conventional electrophysiological investigations are normal. New techniques, such as ESC, provide early diagnosis of small fiber involvement that currently requires more sophisticated tests difficult to apply in routine practice.

Background Recent data have suggested that failure to achieve sustained virological response with direct-acting antiviral therapy is usually due to relapse and is primarily associated with the emergence of resistance-associated substitutions. The aim of this study was to investigate the prevalence and characterization of non-structural-5A resistance-associated substitutions in patients infected with HCV genotypes 1, 3 and 4 treated by direct-acting antiviral therapy, including anti-non-structural-5A, and to characterize the pre-existing resistance-associated substitutions in subjects treated with anti-non-structural-5A inhibitors. Methods From January 2014 to March 2016, 2,995 patients infected with HCV genotypes 1, 3 and 4 were exposed to non-structural-5A inhibitors. Sequencing results at the time of virological failure were available for 61 patients; sequencing at baseline was available for 35 of these patients. Results Among the 35 patients with sequencing results available at baseline, 15 had no resistance-associated substitution, 16 had only one resistance-associated substitution, and 4 had more than one resistance-associated substitution. Resistance-associated substitutions were harbored in 57% of the sequences in the non-structural-5A region. Among the 61 patients sequenced at virological failure, 50 (82%) patients presented at least one resistance-associated substitutions inducing a high level of resistance to non-structural-5A inhibitors (>10-fold resistance). Conclusions This pooled analysis suggests that non-structural-5A resistance-associated substitutions screening should be recommended when considering retreatment with a non-structural-5A inhibitor regimen in patients who have previously experienced failed non-structural-5A treatment.

The Barcelona Clinic Liver Cancer classification is the most widely - used hepatocellular carcinoma (HCC) staging system because it is simple, precise and linked to a treatment algorithm based on randomized studies. But each group includes a broad spectrum of tumors, with limited therapeutic options, particularly for intermediate and advanced stages. Consequently, different additional scoring systems have been proposed to refine the prognosis and/or to improve the management. But until now, there is no consensus. Liu et al proposes a new scoring system, based on a large HCC cohort, with patients at different stages, treated using diverse modalities. This score includes six parameters used in current practice. It is simple to calculate, reliable, with an ability to predict survival superior to other systems, which also works with our European HCC cohort. The MESH score may be especially useful to differentiate subgroups with different prognosis for each treatment modality.

International audience; Importance: Because inadvertent damage of parathyroid glands can lead to postoperative hypocalcemia, their identification and preservation, which can be challenging, are pivotal during total thyroidectomy.Objective: To determine if intraoperative imaging systems using near-infrared autofluorescence (NIRAF) light to identify parathyroid glands could improve parathyroid preservation and reduce postoperative hypocalcemia.Design, setting, and participants: This randomized clinical trial was conducted from September 2016 to October 2018, with a 6-month follow-up at 3 referral hospitals in France. Adult patients who met eligibility criteria and underwent total thyroidectomy were randomized. The exclusion criteria were preexisting parathyroid diseases.Interventions: Use of intraoperative NIRAF imaging system during total thyroidectomy.Main outcomes and measures: The primary outcome was the rate of postoperative hypocalcemia (a corrected calcium

Background & AimLiver fibrosis screening in primary care population is a major public health issue. The FIB-4 index is a simple non-invasive fibrosis test combining age, transaminases, platelets count, developed for the diagnosis of advanced fibrosis. The aim of our study was to evaluate the interest of liver fibrosis screening using systematic calculation of FIB-4 in routine blood analysis.MethodsBetween December 2018 and May 2019, we conducted a prospective screening of liver fibrosis in 134 158 patients during a medical check-up including routine blood analysis. Among these patients, 29 707 had transaminases and platelets counts available and benefited from an automatic calculation of FIB-4. Results were obtained from 21 French clinical laboratories in the Bouches du Rhône region.ResultsAmong the 29 707 patients, 2160 (7.3%) had significant fibrosis (FIB-4>2.67). Individual investigation of patients with FIB-4>2.67 allowed to screen 1267 (1267/2160: 59%) patients who were not managed for any liver disease.ConclusionsThis work demonstrates the interest of FIB-4 for the screening of liver fibrosis in primary care population. Our study strongly supports this easy-to-implement strategy using a simple Fib-4 measure resulting from the use of available routine test results.FundingThis research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.Clinical Registering NumberMR-0314071019 (INDS: French National Institute for Medical Data)

Background The use of intracardiac electrograms to guide atrial fibrillation (AF) ablation has yielded conflicting results. Objectives The authors evaluated the usefulness of spatiotemporal dispersion, a visually recognizable electric footprint of AF drivers, for the ablation of all forms of AF. Methods The authors prospectively enrolled 105 patients admitted for AF ablation. AF was sequentially mapped in both atria with a 20-pole PentaRay catheter. The authors tagged and ablated only regions displaying electrogram dispersion during AF. Results were compared to a validation set in which a conventional ablation approach was used (pulmonary vein isolation/stepwise approach). To establish the mechanism underlying spatiotemporal dispersion of AF electrograms, the authors conducted realistic numerical simulations of AF drivers in a 2-dimensional model and optical mapping of ovine atrial scar-related AF. Results Ablation at dispersion areas terminated AF in 95% of the 105 patients. After ablation of 17 ± 10% of the left atrial surface and 18 months of follow-up, the atrial arrhythmia recurrence rate was 15% after 1.4 ± 0.5 procedures per patient versus 41% in the validation set after 1.5 ± 0.5 procedures per patient (arrhythmia free-survival: 85% vs. 59%; log-rank p Conclusions The clustering of intracardiac electrograms exhibiting spatiotemporal dispersion is indicative of AF drivers. Their ablation allows for a nonextensive and patient-tailored approach to AF ablation. (Substrate Ablation Guided by High Density Mapping in Atrial Fibrillation [SUBSTRATE HD]; NCT02093949)

Objectives This study sought to evaluate the impact of a complex fractionated atrial electrogram (CFAE)–guided ablation strategy on atrial fibrillation (AF) dynamics in patients with persistent AF. Background It is still unclear whether complete pulmonary vein isolation (PVI) is required or if the ablation of well-delineated pulmonary vein (PV) subregions could achieve similar outcomes in persistent AF. Methods CFAE-guided ablations were performed in 76 patients (65.2 ± 10 years of age) with persistent AF. In 47 patients, we measured mean PVs and left atrial appendage (LAA) cycle length (CL) values (PV-CL and LAA-CL), before ablation and before AF termination. We defined “active” PVs as PV-CL ≤ LAA-CL, “rapid fires” as PV-CL ≤80% of LAA-CL, and “PV-LAA CL gradient” as a significant CL difference between the 2 regions. Results AF termination (sinus rhythm [SR] or atrial tachycardia [AT] conversion) occurred in 92% and SR conversion in 75%. The radiofrequency time for AF termination and total radiofrequency time were 26 ± 25 min and 61.1 ± 21.6 min, respectively. Thirty of 47 patients had active PV (with 19 PV “rapid fires”). Ablation significantly increased median CL, both at PVs and LAA from 188 ms (interquartile range [IQR]: 161 to 210 ms) to 227.5 ms (IQR: 200 to 256 ms) (p Conclusions CFAE-guided ablation leads to a large decrease in PV frequency of activation, preceding AF termination. A PV modulation approach, rather than complete PVI, may be preferable for persistent AF.

Background Endoscopic access to common bile duct (CBD) remains difficult in 10% of cases, requiring alternative techniques. This retrospective study with historical controls aimed to evaluate the benefit of the double guidewire (DGW) technique as part of a standardized protocol in CBD access, after failure of standard cannulation and to compare successful CBD access rates, complication rates and length of hospital stay (LOS) in two groups. Method From January 2012 to December 2014, all consecutive patients requiring therapeutic endoscopic retrograde cholangiopancreatography (ERCP) with “difficult” access to CBD were included in a “studied group”. CBD access was “difficult” after either: 5 unsuccessful attempts, 5 unintentional insertions in the pancreatic duct or more than 10-minute-long unsuccessful attempts. This group was compared to a historical control group undergoing ERCP from January 2009 to December 2011. In the studied group, a sequential strategy including DGW technique was performed when the guidewire was unintentional passed into the pancreatic duct. In the control group, only precut technique was used. Results Among the 538 patients with naive papilla eligible for ERCP, 73 had difficult CBD access. Successful CBD access rate was higher in the studied group: 91%(50/55) vs 67%(12/18) p=0.0215. Complication rates were similar in both groups: 28% vs 20%, p=0.5207. LOS was shorter in the studied group (9.2±8.5 days vs. 14.4±7.4 days, p=0.0028). Post-ERCP cholangitis were lower in the study group: 2%(1/55) vs 22%(4/18), p = 0.0118. Conclusion After standard cannulation failure, DGW technique increased successful CBD access rate and decreased LOS without increasing complications. This article is protected by copyright.

Background Advanced hepatocellular carcinoma (HCC) includes a wide spectrum of tumors and patients' prognosis after treatment is highly variable. Moreover, therapeutic options based on the Barcelona Clinic Liver Cancer (BCLC) staging system algorithm are restricted to one systemic therapy. Aim of the study To refine the stratification among BCLC C HCC patients by establishing a new simple prognostic score. Patients and methods A regression model based on a BCLC stage C population and validated with an external cohort of BCLC C HCC patients defined the score. It was therefore validated among three external cohorts of BCLC C HCC patients treated with sorafenib. Results Five variables had independent prognostic values: the number of nodules, the infiltrating nature of the HCC, alpha-fetoprotein serum level, Child-Pugh score, and Eastern Cooperative Oncology Group Performance Status grade. They were integrated into a new score named NIACE ranging from 0 to 7, well correlated with survival. With the use of one threshold value, this score enables defining of two populations with different survivals among BCLC C patients and specifically among those treated with sorafenib. Conclusion The NIACE score defines different prognostic subgroups after palliative treatment of HCC. It could be an additional tool for BCLC C HCC before inclusion in clinical trials or for the management of patients. These results must be validated in a prospective study

Background The aim of this prospective multicenter study was to compare a flexible 19 G needle with nitinol shaft (19 G Flex) with a standard 22 G needle for transduodenal endoscopic ultrasound (EUS)-guided sampling of pancreatic head tumors. Methods Patients with pancreatic head tumors requiring tissue diagnosis were randomized into two arms: puncture with either a 19 G Flex needle or a 22 G needle. The primary end point was diagnostic accuracy for malignancy. The secondary end points were ergonomic scores, sample cytohistological quality, and complications. A 6-month follow-up was performed. Results 125 patients were randomized and 122 were analyzed: 59 patients in the 19 G Flex arm and 63 patients in the 22 G arm. The final diagnosis was malignancy in 111 patients and benign condition in 11. In intention-to-treat analysis, the diagnostic accuracy for malignancy of the 19 G Flex and 22 G needles was 69.5 % (95 % confidence interval [CI] 56.1 % – 80.8 %) vs. 87.3 % (95 %CI 76.5 % – 94.4 %), respectively (P = 0.02). In per-protocol analysis excluding eight technical failures in the 19 G Flex group, the diagnostic accuracy of the 19 G Flex and 22 G needles was not statistically different: 80.4 % (95 %CI 66.9 % – 90.2 %) vs. 87.3 % (95 %CI 76.5 % – 94.4 %; P = 0.12). Technical success was higher in the 22 G arm than in the 19 G Flex arm: 100 % (95 %CI 94.3 % – 100 %) vs. 86.4 % (95 %CI 75.0 % – 94.0 %), respectively (P = 0.003). Transduodenal EUS-guided sampling was more difficult with the 19 G Flex (odds ratio 0.68, 95 %CI 0.47 – 0.97). Conclusion The 19 G Flex needle was inferior to a standard 22 G needle in diagnosing pancreatic head cancer and more difficult to use in the transduodenal approach.

International audience; BACKGROUND & AIMS:Transarterial chemoembolization (TACE) is the standard of care for intermediate stage hepatocellular carcinoma (HCC) and it is the most commonly used treatment for HCC worldwide. However, no prognostic indices, designed to select appropriate candidates for repeat conventional TACE, have been incorporated in the guidelines.METHODS:From January 2007 to April 2012, 139 consecutive HCC patients, mainly with an alcohol- or viral-induced disease, were treated with TACE. Using a regression model on the prognostic variables of our population, we determined a score designed to help for repeat TACE and we validated it in two cohorts. We also compared it to the ART score.RESULTS:In the multivariate analysis, four prognostic factors were associated with overall survival: BCLC and AFP (>200 ng/ml) at baseline, increase in Child-Pugh score by ⩾2 from baseline, and absence of radiological response. These factors were included in a score (ABCR, ranging from -3 to +6), which correlates with survival and identifies three groups. The ABCR score was validated in two different cohorts of 178 patients and proofed to perform better than the ART score in distinguishing between patients' prognosis.CONCLUSIONS:The ABCR score is a simple and clinically relevant index, summing four prognostic variables endorsed in HCC. An ABCR score ⩾4 prior to the second TACE identifies patients with dismal prognosis who may not benefit from further TACE sessions.

High-risk human papillomaviruses (HPVs) have been identified as the main contributors to cervical cancer. Despite various diagnostic tools available, including the predominant Papanicolaou test (Pap test), technical limitations affect the efficiency of cervical cancer screening. The aim of this study was to evaluate the diagnostic performance of spliced HPV16 E6/E7 mRNA viral loads (VL) for grade 2 or higher cervical intraepithelial neoplasia diagnosis. A new dedicated (quantitative reverse transcription polymerase chain reaction) qRT-PCR assay was developed, allowing selective quantification of several HPV16 E6/E7 mRNA: Full length (FL) with or without all or selected spliced forms (total E6/E7 mRNA corresponding to SP + E6^E7 mRNA (T), + spliced E6/E7 mRNA containing intact E7 ORF (SP), and E6/E7 mRNA containing disrupted E6 and E7 ORFs calculated by the following subtraction T-SP (E6^E7)). Twenty HPV16 DNA and mRNA positive uterine cervical smears representative of all cytological and histological stages of severity were tested. We have shown that all E6/E7 mRNA isoforms expression levels were significantly increased in high grade cervical lesions. Statistical analysis demonstrated that the SP-E6/E7 VL assay exhibited: (i) The best diagnostic performance for identification of both cervical intraepithelial neoplasia (CIN)2+ (90% (56&ndash, 100) sensitivity and specificity) and CIN3+ (100% (72&ndash, 100) sensitivity and 79% (49&ndash, 95) specificity) lesions, (ii) a greater sensitivity compared to the Pap test for CIN2+ lesions detection (80% (44&ndash, 97)), (iii) a predictive value of the histological grade of cervical lesions in 67% of atypical squamous cells of unknown significance (ASC-US) and 100% of low-grade (LSIL) patients. Overall, these results highlight the value of SP-E6/E7 mRNA VL as an innovative tool for improving cervical cancer screening.

We have read with interest the article by Pecorelli et al(1) regarding a new therapeutic approach in intermediate stage hepatocellular carcinoma (HCC). In this retrospective analysis, curative treatments (surgery and percutaneous treatments) offer a better outcome compared to the recommended treatment, transarterial chemoembolization (TACE). The strength of this study is the use of propensity score matching and we would like to make few comments to highlight the relevance as well as the limitations of these findings.

Summary Background The impact of the IL28B genotype on the real-life treatment decisions for patients infected with the hepatitis C virus (HCV) is unknown. Objective To prospectively analyze the impact of IL28B genotype in HCV genotype 1 (G1)- or 4 (G4)-infected patients using buccal epithelial cell samples in real-life clinical practices. Patients and methods From October 2011 to March 2013, 1007 CHC patients were included among 127 French clinical centers. Results The IL28B CC, CT, and TT genotype distribution was 252 (25%), 576 (57%), and 177 (18%), respectively. The treatment decisions were recorded and matched with the initial intentions for 433 patients. Multivariate analysis on intention to start treatment showed that patients with HCV G4 were less likely to be intended to be treated than HCV G1 patients (odds ratio [OR] = 0.43 [95% CI 0.19–0.97], P = 0.04); similarly HIV-HCV coinfected patients were less likely to be intended to be treated than HCV monoinfected patients (OR = 0.20 [0.09–0.41], P P = 0.004). Multivariate analysis on final decision to treat showed that Patients with F3–F4 were more likely to be treated than others (OR = 2.06 [1.26–3.38], P = 0.004). Conversely, although P -values are not significant, patients recruited in public hospitals tended to be less treated (OR = 0.65 [0.40–1.04], P = 0.069), similarly to HIV-HCV coinfected patients (OR = 0.55 [0.28–1.11], P = 0.095). Conclusion Our study showed that the IL28B genotype is used for the management of HCV-infected patients. In the context of future treatments, IL28B genotyping may remain useful if it can be used to develop individualized treatment strategies, identifying patients who can be successfully treated with shorter, simpler, or cheaper regimens.

Background: Men who have sex with men (MSM) are disproportionately affected by sexually transmitted infection. The aim of this cross-sectional study is to prospectively detect the prevalence of chlamydia trachomatis (CT), neisseria gonorrhoeae (NG), mycoplasma genitalium (MG), and high risk human papillomavirus (HR-HPV), and syphilis in a population of asymptomatic sexually active MSM. Methods: Rectal, pharyngeal, and urine samples for CT, NG, MG, and HR-HPV were analyzed in 116 MSM patients attending the clinic for their routine follow-up during the period the study was conducted: 99 patients were issued from the clinic routine follow-up for their HIV infection, and 17 attended the clinic because they were sexual partners of an HIV infected male. Results: An STI was found in 16% of the patients (19/116), with at least one bacterial strain (CT, NG, or MG) found in one site (the pharynx, rectum, or urine). Conclusions: In this study, 16% of the MSM reporting recent RAI were asymptomatic carriers of rectal CT, NG, or MG. According to the high prevalence of asymptomatic STIs found in our MSM population and in other studies, prevention efforts in the form of counseling about the risk of STI need to be done in the population of MSM.

The role of pulmonary veins (PVs) in persistent atrial fibrillation (AF) perpetuation appears less important than in paroxysmal AF. Electrogram-based substrate ablation is not widely performed as a stand-alone strategy.To evaluate PV activity in AF perpetuation and efficacy of our patient-tailored ablation strategy (electrogram-based substrate ablation with or without pulmonary vein isolation [PVI]).One hundred twenty-one patients with paroxysmal (n = 19; 15.7%), persistent (n = 77; 63.6%), or long-standing persistent (n = 25; 20.7%) AF underwent electrogram-based substrate ablation with AF termination end point: sinus rhythm or atrial tachycardia conversion. Before ablation, we classified PVs as "passive" if silent PV or if PV cycle length is greater than left atrial appendage cycle length. No PVI was performed in such cases.Passive PVs were observed in 52 of 121 patients (paroxysmal AF = 0%, persistent AF = 40%, and long-standing persistent AF = 76%; P.0001]). Substrate ablation terminated AF in 95.6% (sinus rhythm conversion in 80.2%). Compared with patients with active PVs, patients with passive PVs had longer AF sustained duration (19.1 ± 29.7 months vs 4.9 ± 11.1 months; P.0001), larger left atrial diameter (46.9 ± 7.3 mm vs 41.9 ± 6.0 mm; P = .0014), lower left ventricular ejection fraction (45.4% ± 13.5% vs 55.1% ± 9.4%; P.0001), and more often structural heart disease (57% vs 33%; P = .02). After a follow-up of 20.39 ± 11.23 months (1.6 procedures per patient), 82% were arrhythmia free with this strategy.PV activity during AF decreases with AF chronicity, left atrial dilatation, and left ventricular ejection fraction. Our patient-tailored ablation strategy without systematic PVI provides good results.

Background and objective The aim of this study was to prospectively evaluate whether the addition of peg-IFN to a stable NA regimen leads to loss of HBsAg in HBeAg-negative patients with chronic hepatitis and HBV DNA fully suppressed by long-term NA treatment. Study design We analyzed HBsAg levels in 10 HBsAg-positive, HBeAg-negative patients who received peg-IFN alpha-2a in addition to a NA regimen. Treatment lasted a maximum of 96 weeks, according to changes in the HBsAg titer. Before peg-IFN therapy, HBV DNA levels had been below the limit of detection for at least three years. Results HBsAg levels declined in nine patients. Among these nine, four became HBsAg-negative after 48 weeks of peg-IFN treatment; these patients received peg-IFN for only 48 weeks. NAs were stopped in these four patients, and these levels remained stable for at least 18 months (loss of HBsAg; HBV-DNA negative). HBs seroconversion was observed in two patients. The remaining five patients received 96 weeks of peg-IFN therapy. One patient became HBsAg-negative at the end of peg-IFN therapy; another became HBsAg-negative six months later. Three patients did not become HBsAg-negative. NAs were stopped in the two patients who became HBsAg-negative with no relapse during 12 months of follow up. Conclusions In HBsAg-positive, HBeAg-negative patients with HBV DNA were fully suppressed by long-term NA treatment, the addition of peg-INF for a maximum of 96 weeks based on HBsAg-titer monitoring led to a loss of HBsAg and cessation of NA therapy in six out of ten patients, with no relapse for 12–18 months of follow up. HBs seroconversion was observed in two patients.

STUDY QUESTION: Can independent predictors of pregnancy-associated plasma protein-A (PAPP-A) levels be identified in a group of women who conceived following IVF/ICSI? SUMMARY ANSWER: The significantly decreased PAPP-A level in IVF and ICSI pregnancies compared with non-IVF/ICSI pregnancies was correlated strongly with the serum estradiol (E2) level at ovulation triggering. WHAT IS KNOWN ALREADY: The first trimester prenatal combined screening test for fetal aneuploidies in pregnancies conceived following assisted reproduction techniques (ART) is complicated by an alteration of the maternal biomarkers free β-hCG and PAPP-A, causing a higher false-positive rate compared with pregnancies which are conceived naturally. The use of controlled ovarian stimulation prior to IVF/ICSI is suggested to be the principle reason for these alterations of biomarkers in ART pregnancies. STUDY DESIGN, SIZE, DURATION: Between January 2010 and December 2011, 1474 women who conceived naturally and 374 women who conceived following IVF (n = 89), ICSI (n = 204) or intrauterine insemination (IUI, n = 81) were included in this retrospective study. Only singleton pregnancies were eligible for this study. For all women, serum analysis was performed in the same clinical laboratory. Measurement of nuchal translucency (NT) thickness was performed by four physicians belonging to the same infertility centre. PARTICIPANTS/MATERIALS, SETTING, METHODS: First-trimester combined screening test of aneuploidy parameters (maternal age, PAPP-A and free β-hCG, NT thickness) were compared between non-ART and ART (IVF, ICSI and IUI) singleton pregnancies. Next, a minimal threshold E2 level at ovulation triggering was suggested for IVF/ICSI pregnancies above which the PAPP-A levels were significantly decreased compared with non-ART pregnancies. Finally, a multivariate analysis was performed to reveal independent predictors of PAPP-A level in IVF/ICSI pregnancies. MAIN RESULTS AND THE ROLE OF CHANCE: We showed a decrease of the multiple of the median (MoM) PAPP-A level in IVF and ICSI singleton pregnancies compared with non-ART singleton pregnancies (P < 0.001), with MoM values of 0.74 (0.16-3.16) and 0.81 (0.12-4.61) versus 0.98 (0.14-5.76), respectively. Analysis of variance of the overall model was highly significant (Fisher test 3.76, P = 0.01), indicating that the model explains a significant portion of the variation in the data. No difference in PAPP-A level was found between non-ART and IUI pregnancies. The free β-hCG level and NT thickness did not differ between ART and non-ART pregnancies. PAPP-A levels in IVF and ICSI pregnancies were strongly correlated with the E2 level at ovulation triggering. We showed by multivariate analysis that an E2 cut-off level of 1300 pg/ml at the time of ovulation could predict a significantly lower PAPP-A level at first trimester combined screening (β -0.239 ± 0.088, P < 0.005). LIMITATION, REASONS FOR CAUTION: The measures of biochemical markers can differ between laboratories and with the used equipment; therefore, extrapolation of the E2 cut-off level to other infertility centres should be undertaken with caution. WIDER IMPLICATIONS OF THE FINDINGS: One should be careful when using correction factors for ART patients undergoing the first trimester combined screening test. The proposed E2 cut-off level may help to identify a subgroup of women within the population of ART patients for whom use of a correction factor is justified. STUDY FUNDING/COMPETING INTEREST(S): None.

BACKGROUND AND AIMS Hepatocellular carcinoma (HCC) prognostic scores could be useful in addition to the Barcelona Clinic Liver Cancer (BCLC) system to clarify patient prognosis and guide treatment decision. The NIACE (tumor Nodularity, Infiltrative nature of the tumor, serum Alpha-fetoprotein level, Child-Pugh stage, ECOG performance status) score distinguishes different prognosis groups among BCLC A, B, and C HCC patients. Our aims are to evaluate the NIACE score and its additive value in two HCC cohorts treated either by surgery or by chemoembolization, and then according to the BCLC recommendations. PATIENTS AND METHODS This was a retrospective multicenter study with two BCLC A, B, and C HCC cohorts treated either by surgery (n=207) or by chemoembolization (n=168) carried out between 2008 and 2013. We studied survival time according to the baseline NIACE score and compared it with the Cancer of the Liver Italian Program score and the BCLC system. RESULTS The NIACE score differentiates between subgroups of patients with different prognosis within each BCLC class. Among BCLC A patients treated by surgery and BCLC B patients treated by chemoembolization, the NIACE score differentiates between two subgroups with a significant difference in survival time: 68 (55-81) months versus 35 (21-56) months (P=0.0004) and 20 (17-24) months versus 13 (7-17) months (P=0.0008), respectively. Among those subgroups, the NIACE score has a significantly better prognostic value than the BCLC system or the Cancer of the Liver Italian Program score. CONCLUSION In this study, among HCC patients treated according to the BCLC recommendations, the NIACE score predicts more accurately than any other system the survival time.

The clinical impact of intraoperative autofluorescence-based identification of parathyroids using a near-infrared camera remains unknown.In a before and after controlled study, we compared all patients who underwent total thyroidectomy by the same surgeon during Period 1 (January 2015 to January 2016) without near-infrared (near-infrared- group) and those operated on during Period 2 (February 2016 to September 2016) using a near-infrared camera (near-infrared+ group). In parallel, we also compared all patients who underwent surgery without near-infrared during those same periods by another surgeon in the same unit (control groups). Main outcomes included postoperative hypocalcemia, parathyroid identification, autotransplantation, and inadvertent resection.The near-infrared+ group displayed significantly lower postoperative hypocalcemia rates (5.2%) than the near-infrared- group (20.9%; P .001). Compared with the near-infrared- patients, the near-infrared+ group exhibited an increased mean number of identified parathyroids and reduced parathyroid autotransplantation rates, although no difference was observed in inadvertent resection rates. Parathyroids were identified via near-infrared before they were visualized by the surgeon in 68% patients. In the control groups, parathyroid identification improved significantly from Period 1 to Period 2, although autotransplantation, inadvertent resection and postoperative hypocalcemia rates did not differ.Near-infrared use during total thyroidectomy significantly reduced postoperative hypocalcemia, improved parathyroid identification and reduced their autotransplantation rate.

Le Dual-Knife® (Olympus) est un nouveau couteau frequemment utilise pour la dissection sous-muqueuse du fait de sa surete et de sa precision. L’objet de cette etude etait d’evaluer l’efficacite et la tolerance du traitement endoscopique du diverticule de Zenker avec le Dual-Knife® assiste d’un diverticuloscope (Cook®). De fevrier 2009 a octobre 2011, 21 patients (14 hommes et sept femmes) dont l’âge moyen etait de 70,7 ± 10,2 ans, presentant un diverticule de Zenker symptomatique, ont ete inclus dans une etude prospective multicentrique non randomisee. La myotomie du muscle cricopharyngien etait realisee avec le Dual-Knife® apres exposition du septum diverticulaire grâce au diverticuloscope. En fin de procedure, un ou deux clips etaient positionnes a l’extremite distale de la dissection. Tous les patients decrivaient des symptomes incluant une dysphagie (n = 15; 71,4 %), des regurgitations et/ou troubles de la deglutition (n = 19; 90 %). Seize patients (75 %) avaient un diverticule dont la profondeur etait superieure ou egale a 30 mm. Toutes les complications etaient notees. Les symptomes des patients (dysphagie, regurgitation, troubles de la deglutition et inhalations) etaient evalues lors de consultations de surveillance regulieres ou par telephone. Le test utilise determine la probabilite que les deux parametres soient fortement lies au seuil p = 0,05 (test CMH). Une p-value inferieure a 0,05 indique une forte liaison entre les deux parametres, donc on accepte l’hypothese qu’il n’y a pas d’effet traitement. Les donnees ont ete analysees a l’aide du logiciel SAS (version 9.2; SAS Institute Inc, Cary, NC). Tous les patients ont ete traites avec succes lors de la premiere session. Nous n’avons eu aucune complication grave. Une hemorragie immediate a ete traitee endoscopiquement avec succes a l’aide d’une pince d’hemostase. Tous les patients sont sortis dans les 48 heures suivant l’intervention. A un mois et au moment de l’evaluation de suivi (7,85 mois [3–12]), la dysphagie et les regurgitations etaient significativement ameliorees (p = 0,48/0,18 et 0,68/,041 respectivement). Dix-huit patients (85,7 %) n’avaient plus aucun symptome. Pour trois patients, la dysphagie et/ou les regurgitations persistaient de manieres plus moderees. La dysphagie et/ou les regurgitations ont recidive pour deux patients (9,5 %). Un deuxieme traitement endoscopique a ete necessaire et un patient a ete opere. Au final, le traitement endoscopique etait efficace dans 90,4 % des cas. La diverticulotomie endoscopique au Dual-Knife® aide du diverticuloscope est une alternative therapeutique sure et efficace pour des patients atteints d’un diverticule de Zenker symptomatique.

BACKGROUND: Recent studies have suggested that host genetics may be useful for predicting drug response and have supported the recommendation that single polynucleotide polymorphisms (SNPs) of IL28B should be investigated when treating hepatitis C virus (HCV)-1 infected patients. The aim of this study was to determine whether a single IL-28B genotype SNP rs8099917 or rs12979860 determination is sufficient to predict treatment failure in patients with chronic HCV. METHODS: A total of 198 patients were included; mean (±standard deviation) age was 47±12 years and 140 (71%) were men. One hundred and fifty-six (79%) patients were infected with HCV genotype 1 and 42 (21%) with HCV genotypes 2 or 3. One hundred and eight (55%) patients had sustained virologic response (SVR). Two SNPs in the IL-28B were analyzed (rs8099917 and rs12979860). RESULTS: A total of 115 (58%) patients had rs8099917 TT genotype and 61 (31%) had rs12979860 CC genotype. Rs8099917 TT and rs12979860 CC genotypes were associated with SVR in HCV genotype 1 patients [odds ratio=2.60 (1.36-5.00), P=0.004 and odds ratio=3.30 (1.58-6.90), P=0.03 respectively]. No association was found between SNPs and SVR in HCV genotype 2 or 3 patients. CONCLUSION: This study confirms that SNPs rs8099917 and rs12979860 used alone may be useful for predicting the outcome of HCV treatment. In a rational and cost-effective approach, determination of only one of these two SNPs is sufficient for predicting SVR. Because of the highest predictive SVR associated with rs12979860 CC compared with the rs8099917 TT (respective positive predictive value: 72% vs. 63%, P=ns), rs12979860 determination alone is sufficient for predicting interferon response.

Preemptive therapy in hematopoietic cell transplantation is initiated by a diagnostic technique at first detection of cytomegalovirus (CMV). The aim of this study was to use the viral dynamics of CMV DNA viral to start preemptive therapy, and to prospectively compare the CMV viral load kinetics to pp65 antigenemia. Two hundred sixty-three blood samples were collected prospectively from 93 patients. All clinical decisions regarding use of preemptive therapy were based on CMV antigenemia. Based on the positivity of the antigen assay and clinical CMV outcome in allotransplant patients, an optimal threshold of 3.05 log 10 (1,130 copies/ml) was found to discriminate patients who required preemptive therapy and those who did not (sensitivity, 71%; specificity, 65%). A DNAemia level increase of 2.24 log 10 (174 copies/ml) per day was the optimal threshold to discriminate between patients who required preemptive therapy and those who did not (sensitivity, 93%; specificity, 43%). Sensitivity of PCR assay was 92.4% compared with 39% for the antigen assay (P

A lack of antiviral response in patients with chronic hepatitis C treated with pegylated (PEG)-interferon (IFN)-α-2a + ribavirin (RIBA) may be explained by neutralizing antibodies to IFN-α-2a. The aim of this study was to assess neutralizing antibodies to IFN-α-2a and IFN levels in non-responder patients who were re-treated by PEG IFN-α-2a and RIBA for 12 weeks. Non-responders to a first-line treatment of PEG IFN-α-2a + RIBA were included for treatment with PEG IFN-α-2a (180 µg/week) + RIBA (1,000 mg/day if

Background The aim of this study was to assess the effect of insulin resistance (IR) on the response to hepatitis C virus (HCV) therapy in HIV-HCV-coinfected patients. Methods A total of 238 HIV-HCV-coinfected patients (74% male, mean ±sd age 40 ±5 years, mean alcohol intake Results IR was present in 32% and significant liver fibrosis (Metavir≥F2) in 74% of patients. Patients with SVR (96/238 [40%]) were more likely to be infected with HCV genotype 2 or 3 (54% versus 27%; P2.5 had a negative effect on the SVR (odds ratio 0.49 [95% confdence interval 0.26-0.92]; P=0.05). Conclusions A high HOMA-IR level is frequently found in HIV-HCV-coinfected patients and is associated with a reduced SVR rate. Improving insulin sensitivity might be a useful adjunct to HCV therapy in HIV-HCV-coinfected patients.

Resume Chez les patients co-infectes VHC-VIH ayant recu un traitement anti-virus de l’hepatite C (VHC), les scores non invasifs de fibrose hepatique semblent plus sensibles que la biopsie hepatique pour la detection d’une evolution de la fibrose, independamment du stade d’activite necrotico-inflammatoire. De nombreuses etudes ont montre qu’il existait une association entre l’insulino-resistance et la fibrose hepatique ainsi qu’une diminution de la reponse au traitement en cas d’insulino-resistance evaluee par le score HOMA. Nous avons evalue le role de l’insulino-resistance sur la steatose et la fibrose hepatique dans une population de malades mono-infectes VHC par comparaison a des sujets co-infectes VHC-VIH. Chez ces derniers, l’insulino-resistance n’etait associee ni a la steatose ni a la fibrose extensive contrairement aux patients VHC mono-infectes. Nous avons egalement evalue le role de l’insulino-resistance sur la reponse au traitement des patients co-infectes VHC-VIH. Les patients ayant une reponse virologique prolongee (40 %) etaient plus souvent infectes par un genotype 2 ou 3. En analyse multivariee, la reponse virologique prolongee etait independamment associee a un HOMA > 2,5 (odds ratio 0,49), a l’âge (odds ratio 0,90), et aux genotypes 2,3 (odds ratio 3,39). En conclusion, l’amelioration de la sensibilite a l’insuline chez ces patients pourrait etre une voie therapeutique complementaire interessante associee aux traitements anti-VHC pour optimiser les chances de guerison virologique.

Background and Aims: Syndecan 1 (CD 138) is a cell surface proteoglycan shed by cells in several pathological conditions, including wound healing. The aim of this study was to test whether CD138 could serve as a non-invasive marker for detection of liver fibrosis and thereby reduce the need for liver biopsy. Patients and Methods: An estimation set of 134 patients and a validation set of 67 patients with chronic hepatitis C were studied. There were 80 normal healthy volunteers. Patients were staged according to liver biopsies (Metavir fibrosis staging, stage F0, n=35; F1, n=40; F2, n=37, F3, n=39; F4, n=51). Serum CD138 levels were retrospectively measured by enzyme-linked immunoabsorbent assay the same day of the liver biopsy. The primary endpoints were the diagnostic values of CD138 for F2–F4, F3–F4 and F4. Results: Respective areas under receiver operating characteristic curve of CD138 for F2–F4, F3–F4 and F4 diagnosis were 0.82, 0.76 and 0.81. CD138 had a positive predictive value of 82% for F2–F4 diagnosis and a high negative predictive value (86%) and specificity (84%) for exclusion of F4. Conclusion: CD138 is a new simple non-invasive marker for predicting liver fibrosis in patients with chronic hepatitis C. The relevance of this marker in combination with other fibrosis markers should be explored.
