RESUMEN

OBJECTIVES: Diagnosis of COVID-19 is essential to prevent the spread of SARS-CoV-2. Nasopharyngeal swabs (NPS) remain the gold standard in screening, although associated with false negative results (up to 30%). We developed a 3D simulator of the nasal and pharyngeal cavities for the learning and improvement of NPS collection. PATIENTS AND METHODS: Simulator training sessions were carried out in 11 centers in France. A questionnaire assessing the simulator was administered at the end of the sessions. The study population included both healthcare workers (HCW) and volunteers from the general population. RESULTS: Out of 589 participants, overall satisfaction was scored 9.0 [8.9-9.1] on a scale of 0 to 10 with excellent results in the 16 evaluation items of each category (HCWs and general population, NPS novices and experienced). The simulator was considered very realistic (95%), easy to use (97%), useful to understand the anatomy (89%) and NPS sampling technique (93%). This educational tool was considered essential (93%). Participants felt their future NPS would be more reliable (72%), less painful (70%), easier to perform (88%) and that they would be carried out more serenely (90%). The mean number of NPS conducted on the simulator to feel at ease was two; technical fluency with the simulator can thus be acquired quickly. CONCLUSION: Our simulator, whose 3D printing can be reproduced freely using a permanent open access link, is an essential educational tool to standardize the learning and improvement of NPS collection. It should enhance virus detection and thus contribute to better pandemic control.

RESUMEN

BACKGROUND: Although the burden of TB is lower in France than in low-income countries, patients continue to die from TB in Paris. Our goal was to describe TB-related deaths and to identify associated risk factors.METHODS: We conducted a retrospective cohort study in two hospitals in Paris between 2013 and 2018. All patients with drug-susceptible TB were included and followed until end of treatment. The primary outcome was death. We performed univariate and multivariate analysis using Cox proportional hazard model.RESULTS: Of the 523 patients included, 362 were men (median age 37 years), of whom 24 patients died (4.5%). The final survival model concluded that age (HR 1.1 for each additional year), not living in one´s own accommodation (HR 5.9), being born in France (HR 8.0), being alcoholic (HR 4.2), having a history of cancer (HR 7.1) or meningeal or miliary TB (HR 8.2) were associated with a higher risk of death.CONCLUSION: The rate of TB-associated death is unacceptably high for a curable disease. To note, patients born in France were much more at risk of death than immigrants. We believe raising awareness among healthcare professionals is a potentially easy and efficient lever for improving care.

RESUMEN

Recent evidence showed greater efficacy of tocilizumab (TCZ) in the subgroups of COVID-19 patients who presented with symptoms for less than 7 days and in those only receiving oxygen. We retrospectively analyzed a compassionate use cohort to determine the best timing for TCZ injection. We showed no association between the timing of injection after symptom onset and the efficacy of TCZ on mortality. We then investigated whether the oxygen level at the time of TCZ injection impacted the mortality rate. Our study finally suggested that TCZ could be less effective when oxygen requirement is >11L/min and we hypothesized that earlier administration could be associated with better outcome. However, randomized clinical trials are required to confirm this hypothesis.

RESUMEN

Chronic hepatitis B infection remains a major public-health problem, with approximately 260 million world-wide cases of infection. Recent advances in the understanding of the natural history of chronic hepatitis B infection have led to progress in the care of infected patients. Sustained viral suppression is now possible for a majority of treated patients and is associated with a decrease in the morbidity and mortality attributable to cirrhosis and hepatocellular carcinoma. Complete cure is however not yet possible, due to the long-term persistence of viral DNA in hepatocytes of treated patients. Assessing the risk of viral reactivation in patients receiving immunosuppressive therapy is an increasingly frequent situation in clinical practice and its management is guided by both the patient's serological status and the potency of the immunosuppressive regimen. This review aims to present the clinical and biological presentations of chronic hepatitis B infection, the modalities of antiviral treatment, and how to assess the risk of viral reactivation in patients receiving immunosuppressive therapy.

RESUMEN

When assessing hepatitis B virus (HBV) status in clinical settings, it is unclear whether self-reports on vaccination history and previous HBV-test results have any diagnostic capacity. Of 3997 participants in a multi-centre HBV-screening study in Paris, France, 1090 were asked questions on their last HBV-test result and vaccination history. Discordance between self-reported history compared with infection status (determined by serology) was calculated for participants claiming 'negative', 'effective vaccine', 'past infection', or 'chronic infection' HBV-status. Serological testing revealed that 320 (29.4%) were non-immunised, 576 (52.8%) were vaccinated, 173 (15.9%) had resolved the infection and 21 (1.9%) were hepatitis B surface antigen positive. In total 208/426 (48.8%) participants with a self-reported history of 'negative' infection had a discordant serological result, in whom 128 (61.5%) were vaccinated and 74 (35.6%) had resolved infections. A total of 153/599 (25.5%) participants self-reporting 'effective vaccine' had a discordant serological result, in whom 100 (65.4%) were non-immunised and 50 (32.7%) were resolved infections. Discordance for declaring 'past' or 'chronic infection' occurred in 9/55 (16.4%) and 3/10 (30.0%) individuals, respectively. In conclusion, self-reported HBV-status based on participant history is partially inadequate for determining serological HBV-status, especially between negative/vaccinated individuals. More adapted patient education about HBV-status might be helpful for certain key populations.

RESUMEN

The nucleotide substitution G1896A on the precore (pc) region has been implicated in virological and serological responses during treatment in hepatitis B virus (HBV)-infected patients. Whether this mutation affects the therapeutic course of HIV-HBV co-infected patients, especially from Western Africa, is unknown. In this prospective cohort study, 86 antiretroviral (ARV)-naïve HIV-HBV co-infected patients from Côte d'Ivoire, initiating ARV-treatment containing lamivudine (n = 53) or tenofovir (n = 33), had available baseline pc sequences. Association of the pcG1896A mutation with time to undetectable HBV-DNA, hepatitis B "e" antigen (HBeAg) seroclearance (in HBeAg-positive patients), and hepatitis B surface antigen (HBsAg) seroclearance was evaluated using Cox proportional hazards regression. At ARV-initiation, median HBV-DNA was 6.04 log10 copies/mL (IQR = 3.70-7.93) with 97.7% harbouring HBV genotype E. Baseline pcG1896A mutation was identified in 51 (59.3%) patients, who were more commonly HBeAg-negative (P < .001) and had basal core promotor A1762T/G1764A mutations (P < .001). Patients were followed for a median 36 months (IQR = 24-36). Cumulative proportion of undetectable HBV-DNA was significantly higher in patients with baseline mutation (pcG1896A = 86.6% vs no pcG1896A = 66.9%, P = .04), but not after adjusting for baseline HBV-DNA levels and anti-HBV agent (P = .2). No difference in cumulative proportion of HBeAg seroclearance was observed between mutation groups (pcG1896A = 57.1% vs no pcG1896A = 54.3%, P = .7). Significantly higher cumulative proportion of HBsAg seroclearance was observed in patients without this mutation (pcG1896A = 0% vs no pcG1896A = 36.9%, P < .001), even after adjusting for baseline HBsAg quantification and anti-HBV agent (P < .001). In conclusion, lacking the pcG1896A mutation before ARV initiation appeared to increase HBsAg seroclearance rates during treatment. The therapeutic implications of this mutation need further exploration in this setting.

RESUMEN

OBJECTIVES: Studies evaluating the efficacy and safety of the fixed-dose combination ledipasvir (LDV)/sofosbuvir (SOF) in patients coinfected with HIV-1 and hepatitis C virus (HCV) have mainly included treatment-naïve patients without cirrhosis. We aimed to evaluate the efficacy and safety of this combination in treatment-experienced patients with and without cirrhosis. METHODS: We conducted a multicentre, open-label, double-arm, nonrandomized study in patients coinfected with HIV-1 and HCV genotype 1 with and without cirrhosis, who had good viral suppression on their antiretroviral regimens. All patients were pretreated with a first-generation NS3/4A protease inhibitor (PI) plus pegylated interferon/ribavirin. Patients received a fixed-dose combination of LDV/SOF for 12 weeks, or for 24 weeks if cirrhosis was present. The primary endpoint was a sustained virological response (SVR) 12 weeks after the end of therapy. Secondary endpoints included safety, pharmacokinetics and patient-reported outcomes. RESULTS: Of the 68 patients enrolled, 39.7% had cirrhosis. Sixty-five patients [95.6%; 95% confidence interval (CI): 87.6-99.1%; P < 0.0001] achieved an SVR, with similar rates of SVR in those with and without cirrhosis. Tolerance was satisfactory, with mainly grade 1 or 2 adverse events. Among patient-reported outcomes, only fatigue significantly decreased at the end of treatment compared with baseline [odds ratio (OR): 0.36; 95% CI: 0.14-0.96; P = 0.04]. Mean tenofovir area under the plasma concentration-time curve (AUC) at week 4 was high, with mean ± SD AUC variation between baseline and week 4 higher in cirrhotic than in noncirrhotic patients (3261.57 ± 1920.47 ng/mL vs. 1576.15 ± 911.97 ng/mL, respectively; P = 0.03). Mild proteinuria (54.4%), hypophosphataemia (50.0%), blood bicarbonate decrease (29.4%) and hypokalaemia (13.2%) were reported. The serum creatinine level was not modified. CONCLUSIONS: LDV/SOF provided a high SVR rate in PI-experienced subjects coinfected with HCV genotype 1 and HIV-1, including patients with cirrhosis.

RESUMEN

According to the Global Burden of Diseases, chronic viral hepatitis B and C are one of the most challenging global health conditions that rank among the first causes of morbidity and mortality worldwide. Low- and middle-income countries are particularly affected by the health burden associated with HBV or HCV infection. One major gap in efficiently addressing the issue of viral hepatitis is universal screening. However, the costs and chronic lack of human resources for using traditional screening strategies based on serology and molecular biology preclude any scaling-up. Point-of-care tests have been deemed a powerful potential solution to fill the current diagnostics gap in low-resource and decentralized settings. Despite high interest resulting from their development in recent years, very few point-of-care devices have reached the market. Scaling down and automating all testing steps in 1 single device (eg, sample preparation, detection and readout) is indeed challenging. But innovations in multiple disciplines such as nanotechnologies, microfluidics, biosensors and synthetic biology have led to the creation of chip-sized laboratory systems called "lab-on-a-chip" devices. This review aims to explain how these innovations can overcome technological barriers that usually arise for each testing step while developing integrated point-of-care tests. Point-of-care test prototypes rarely meet the requirements for mass production, which also hinders their large-scale production. In addition to logistical hurdles, legal and economic constraints specific to the commercialization of in vitro diagnostics, which have also participated in the low transfer of innovative point-of-care tests to the field, are discussed.

RESUMEN

The aim of this pilot study was to analyze the Hepatitis C Virus (HCV) genotypes circulating in Senegal among Drug User (DUs), using Dried Blood Spots (DBS) as RNA source for molecular assays. Heroin and/or cocaine users (n = 506) were recruited in Dakar from April to July 2011, using a Respondent Driven Sampling (RDS) method. DBS preparation consisted of five drops of whole blood from finger applied to a Whatman paper card. HCV infection was screened by the detection of anti-HCV antibodies, using a rapid immune-chromatographic test. HCV RNA was quantified on anti-HCV positive DBS, using the Abbott RealTime HCV® Genotyping was performed on DBS with detectable viral load with Versant® HCV Genotype 2.0 Assay (LiPA) and Abbott RealTime HCV Genotype II assay®. Among the 506 participants, 120 were tested as positive for anti-HCV antibodies and their samples were analyzed for HCV RNA viral load and genotype. Out of the 120 DBS tested, HCV RNA was detected on 25 (20.8%). The median viral load was 15,058 IU/ml (ranging from 710 to 766,740 IU/ml). All positive DBS were suitable for the genotyping assay, that showed a predominance of genotype 1 (21/25) including 16 genotypes 1a and 5 genotypes 1b. HCV genotype 1 prevails in a DU population in Dakar. DBS could be useful for HCV RNA genotyping, but optimal storage conditions should required avoiding RNA impairment. Acknowledging this limitation, DBS could be a great interest for detecting and genotyping HCV viremic patients. J. Med. Virol. 89:484-488, 2017. © 2015 Wiley Periodicals, Inc.

RESUMEN

In hepatitis B "e" antigen (HBeAg) positive patients with hepatitis B virus (HBV) mono-infection, intensification of nucleos(t)ide analogue treatment with pegylated interferon (PegIFN) could help induce higher HBeAg seroclearance rates. Our aim was to determine the long-term effect of adding PegIFN to tenofovir (TDF)-containing antiretroviral therapy on seroclearance in HBeAg-positive patients co-infected with the human immunodeficiency virus (HIV) and HBV. In this prospective matched cohort study, 46 patients with 1-year PegIFN intensification during TDF-containing antiretroviral therapy (TDF+PegIFN) were matched 1:1 to controls undergoing TDF without PegIFN (TDF) using a time-dependent propensity score based on age, CD4+ count and liver cirrhosis status. Kinetics of HBeAg quantification (qHBeAg) and hepatitis B surface antigen quantification (qHBsAg) were estimated using mixed-effect linear regression and time to HBeAg seroclearance or HBsAg seroclearance was modelled using proportional hazards regression. At baseline, previous TDF exposure was a median 39.8 months (IQR=21.4-59.4) and median qHBeAg and qHBsAg levels were 6.9 PEIU/mL and 3.72 log10 IU/mL, respectively (P>.5 between groups). Median follow-up was 33.4 months (IQR=19.0-36.3). During intensification, faster average declines of qHBeAg (-0.066 vs -0.027 PEIU/mL/month, P=.001) and qHBsAg (-0.049 vs -0.026 log10 IU/mL/month, P=.09) were observed in patients undergoing TDF+PegIFN vs TDF, respectively. After intensification, qHBeAg and qHBsAg decline was no different between groups (P=.7 and P=.9, respectively). Overall, no differences were observed in HBeAg seroclearance (TDF+PegIFN=13.2 vs TDF=12.6/100 person·years, P=.5) or HBsAg seroclearance rates (TDF+PegIFN=1.8 vs TDF=1.3/100 person·years, P=.7). In conclusion, PegIFN intensification in HBeAg-positive co-infected patients did not lead to increased rates of HBeAg or HBsAg clearance, despite faster declines of antigen levels while on PegIFN.

RESUMEN

OBJECTIVES: The objective of this nested study was to assess the prevalence of psychiatric disorders in a sample of HIV/hepatitis C virus (HCV)-coinfected patients according to their HCV status. METHODS: The nested cross-sectional study, untitled HEPAVIH-Psy survey, was performed in a subset of HIV/HCV-coinfected patients enrolled in the French Agence Nationale de Recherche sur le SIDA et les Hépatites Virales (ANRS) CO13 HEPAVIH cohort. Psychiatric disorders were screened for using the Mini International Neuropsychiatric Interview (MINI 5.0.0). RESULTS: Among the 286 patients enrolled in the study, 68 (24%) had never received HCV treatment, 87 (30%) were treatment nonresponders, 44 (15%) were currently being treated and 87 (30%) had a sustained virological response (SVR). Of the 286 patients enrolled, 121 patients (42%) screened positive for a psychiatric disorder other than suicidality and alcohol/drug abuse/dependence, 40 (14%) screened positive for alcohol abuse/dependence, 50 (18%) screened positive for drug abuse/dependence, 50 (17.5%) were receiving an antidepressant treatment and 69 (24%) were receiving an anxiolytic. Patients with an SVR did not significantly differ from the other groups in terms of psychiatric disorders. Patients receiving HCV treatment screened positive less often for an anxiety disorder. The highest rate of drug dependence/abuse was among HCV treatment-naïve patients. CONCLUSIONS: Psychiatric disorders were frequent in HIV/HCV-coinfected patients and their rates were comparable between groups, even for patients achieving an SVR. Our results emphasize the need for continuous assessment and care of coinfected patients, even after HCV clearance. Drug addiction remains an obstacle to access to HCV treatment. Despite the recent advent and continued development of directly acting antiviral agents (DAAs), it is still crucial to offer screening and comprehensive care for psychiatric and addictive disorders.

RESUMEN

OBJECTIVES: The objective of the 1st European AIDS Clinical Society meeting on Standard of Care in Europe was to raise awareness of the European scenario and come to an agreement on actions that could be taken in the future. METHODS: Data-driven presentations were given on specific topics followed by interactive panel discussions. RESULTS: In Eastern European countries, the epidemic is largely driven by injecting drug use, in contrast with Western Europe where the infection mainly occurs through heterosexual contact. A high proportion of people living with HIV remain unaware of their infection. Substantial differences exist in Eastern Europe and Central Asia with respect to treatment coverage, regimen availability and continuity of drug supply. In 2012, tuberculosis case notification rates were 5-10 times higher in Eastern Europe compared with Western Europe, with an alarming proportion of newly diagnosed multi-drug-resistant cases. Hepatitis C is widespread in selected geographical areas and risk groups. CONCLUSIONS: The key conclusion from the meeting was that a high-priority group of actions could be identified, including: increasing HIV awareness and testing, improving training for health care providers, ensuring equitable patient access to treatments and diagnostics for HIV and comorbidities, and implementing best practices in infection control and treatment of HIV-infected patients coinfected with tuberculosis and hepatitis C virus, for whom direct acting antiviral treatment. should be considered.

RESUMEN

The prevalence and management of chronic hepatitis B virus (HBV) infection differ among European countries. The availability and reimbursement of diagnostics and drugs may also vary, determining distinct treatment outcomes. Herein, we analyse differences in medical facilities for the care of patients with chronic HBV infection across Europe. A survey was sent to the members of the ESCMID Study Group for Viral Hepatitis, all of whom are experts in chronic HBV infection management. The comprehensive survey asked questions regarding hepatitis B surface antigen (HBsAg) prevalence, the availability of diagnostics and drugs marketed, and distinct clinical practice behaviours in the management of chronic HBV infection. World Bank data were used to assess the economic status of the countries. With 16 expert physicians responding (69%), the HBsAg prevalence rates were <1% in France, Hungary, Italy, The Netherlands, Portugal, Spain, and the UK, intermediate (1-5%) in Turkey, Romania, and Serbia, and high (>5%) in Albania and Iran. Regarding the availability and reimbursement of HBV diagnostics (HBV DNA and liver stiffness measurement), HBV drugs (interferon, lamivudine, tenofovir, and entecavir), HBV prophylaxis, and duration of HBeAg-positive and HBeAg-negative HBV infection, the majority of high-income and middle-income countries had no restrictions; Albania, Iran and Serbia had several restrictions in diagnostics and HBV drugs. The countries in the high-income group were also the ones with no restrictions in medical facilities, whereas the upper-middle-income countries had some restrictions. The prevalence of chronic HBV infection is much higher in southern and eastern than in western European countries. Despite the availability of European guidelines, policies for diagnostics and treatment vary significantly across European countries.

RESUMEN

Although preliminary studies showed that preexposure prophylaxis (PrEP) lowers the HIV transmission in individuals with HIV, confirmative trials are ongoing and PrEP is not routinely recommended. The aim of this study was to assess whether individuals with HIV share antiretroviral (ARV) drugs for PrEP and to describe awareness and discussion on PrEP in this population. A cross-sectional survey was conducted in France in 23 representative departments of infectious diseases and internal medicine. Physicians administered an anonymous standardized questionnaire to all individuals with HIV receiving ARVs and followed between 24 and 31 October 2011. The questionnaire included items regarding PrEP (awareness; discussion with their close circle, physician or patients' association; experience), personal sociodemographic characteristics, risk behaviors and HIV status of the participants. Five hundred and ninety three participants were recruited: male 74.2% (men who have sex with men 52.4%, heterosexuals 21.6%), member of patient's association 9.8%. Half of them (50.6%) lived with a stable partner and 35.2% with an HIV-negative partner. Almost half (41.8%) were aware and 29.5% had had discussion about PrEP. In logistic regression, awareness and discussion on PrEP were more frequent: (1) among males, in patients' association members (p< 0.001 for both) and in nonheterosexuals (p=0.023 and 0.057, respectively); (2) among women, in those not living with a stable partner (p=0.035 and p=0.03, respectively) or living with an HIV-negative partner (p=0.049 and p=0.083, respectively). One percent of the participants declared having shared ARVs with someone and 8.3% reported PrEP in their close circle. Men reporting PrEP in their close circle shared ARVs more frequently than those who did not (10.3% vs. 0.2%, p < 0.001). Today, individuals with HIV do not seem to widely share personal ARVs for PrEP with seronegative people. A significant number of individuals with HIV are aware of and commonly discuss PrEP.

RESUMEN

The impact of antiretroviral drug exposure and associated lipodystrophy and/or insulin resistance (IR) on advanced liver fibrosis in HIV/HCV-coinfected patients is not fully documented. We determined the prevalence of advanced liver fibrosis (defined by hepatic stiffness ≥9.5 kPa) and associated factors, focusing on the impact of highly active antiretroviral therapy and its major adverse effects (lipodystrophy and IR), in 671 HIV/HCV-coinfected patients included in the ANRS CO13 HEPAVIH cohort. One hundred ninety patients (28.3%) had advanced liver fibrosis. In univariate analysis, advanced liver fibrosis was significantly associated with male sex, higher body mass index, HCV infection through intravenous drug use, a lower absolute CD4 cell count, a longer history of antiretroviral treatment, longer durations of protease inhibitors, non-nucleoside reverse transcriptase inhibitors and NRTI exposure, lipodystrophy, diabetes, and a high homeostasis model assessment method (HOMA) value. The only antiretroviral drugs associated with advanced liver fibrosis were efavirenz, stavudine and didanosine. In multivariate analysis, male sex (OR 2.0, 95% CI 1.1-3.5; P = 0.018), HCV infection through intravenous drug use (OR 2.0, 95% CI 1.1-3.6; P = 0.018), lipodystrophy (OR 2.0, 95% CI 1.2-3.3; P = 0.01), median didanosine exposure longer than 5 months (OR 1.7, 95% CI 1.0-2.8; P = 0.04) and a high HOMA value (OR 1.1, 95% CI 1.0-1.2; P = 0.005) remained significantly associated with advanced liver fibrosis. Mitochondrial toxicity and IR thus appear to play a key role in liver damage associated with HIV/HCV-coinfection, and this should be taken into account when selecting and optimizing antiretroviral therapy. Antiretroviral drugs with strong mitochondrial toxicity (e.g. didanosine) or a major effect on glucose metabolism should be avoided.

RESUMEN

Transient elastography (TE) is a noninvasive technique to evaluate liver fibrosis. We compared the performance of TE with liver biopsy (LB) in patients with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) coinfection. Patients prospectively underwent TE and LB. The diagnosis accuracy of TE was calculated using receiver operating characteristic (ROC) curves for different stages of fibrosis, and optimal cut-off values were defined. A sequential algorithm combining TE with biochemical score (Fibrotest) is proposed. Fifty-seven patients had both TE and LB (median time: 3 days) and two with proven cirrhosis, only TE. Forty-six (78%) were under antiretroviral therapy with anti-HBV drugs in 98%, and 19 (32%) had elevated alanine aminotransferase (ALT). A significant correlation was observed between liver stiffness measurement (LSM) and METAVIR fibrosis stages (P < 0.0001). Patients with elevated ALT tended to have higher LSM than those with normal ALT. The areas under the ROC curves were 0.85 for significant fibrosis (≥ F2), 0.92 for advanced fibrosis (≥ F3) and 0.96 for cirrhosis. Using a cut-off of 5.9 kPa for F ≥ 2 and 7.6 kPa for F ≥ 3, the diagnosis accuracy was 83% and 86%, respectively. With an algorithm combining TE and Fibrotest, 97% of patients were well classified for significant fibrosis. Using this algorithm, the need for LB can be reduced by 67%. In HIV/HBV-coinfected patients, most of them with normal ALT under antiretroviral treatment including HBV active drugs, TE was proficient in discriminating moderate to severe fibrosis from minimal liver disease.
