Severe Scabies: A French Multi-centre Study Involving 95 Patients with Crusted and Profuse Disease and Review of the Literature.

The aim of this multi-centre French retrospective study was to identify severe, i.e. crusted and profuse, scabies patients. Records were retrieved from 22 Dermatology or Infectious Diseases departments in the Ile-de-France from January 2009 to January 2015 to characterize epidemiology, demography, diagnosis, contributing factors, treatment features, and outcomes in severe scabies. A total of 95 inpatients (57 crusted and 38 profuse) were included. A higher number of cases was observed among elderly patients (>75 years), mostly living in institutions. Thirteen patients (13.6%) reported a history of previously treated scabies. Sixty-three patients (66.3%) had been seen by a previous practitioner for the current episode (up to 8 previous visits). Initial misdiagnosis (e.g. eczema, prurigo, drug-related eruptions, psoriasis) was documented in 41 patients (43.1%). Fifty-eight patients (61%) had already received 1 or more previous treatments for their current episode. Forty percent received corticosteroids or acitretin for an initial diagnosis of eczema or psoriasis. Median time from the onset of symptoms to the diagnosis of severe scabies was 3 months (range 0.3-22). Itch was present in all patients at diagnosis. Most patients (n=84, 88.4%) had comorbidities. Diagnostic and therapeutic approaches varied. Complications occurred in 11.5% of cases. To date, there is no consensus for diagnosis and treatment, and future standardization of is required for optimal management.

Efficacy and safety of direct-acting antiviral regimens in HIV/HCV-co-infected patients - French ANRS CO13 HEPAVIH cohort.

BACKGROUND & AIMS: There is little data available on the use of new oral direct-acting antiviral (DAA) regimens to treat human immunodeficiency virus and hepatitis C virus (HIV/HCV) co-infected patients in real-life settings. Here, the efficacy and safety of all-oral DAA-based regimens in HIV/HCV-co-infected patients enrolled in the French nationwide ANRS CO13 HEPAVIH observational cohort are reported. METHODS: HIV/HCV-co-infected patients enrolled in the ANRS CO13 HEPAVIH observational cohort were included if they began an all-oral DAA-based regimen before 1st May 2015 (12-week regimens) or 1st February 2015 (24-week regimens). Treatment success (SVR12) was defined by undetectable HCV-RNA 12weeks after treatment cessation. Exact logistic regression analysis was used to identify factors associated with SVR12. RESULTS: A total of 323 patients (74% men) with a median age of 53years were included, 99% of whom were on combination antiretroviral therapy (cART). HIV RNA load was <50 copies/ml in 88% of patients; median CD4 cell count was 540/mm3; 60% of patients were cirrhotic; 68% had previously received unsuccessful anti-HCV treatment. cART was protease inhibitor (PI)-based in 23%, non-nucleoside reverse transcriptase inhibitor (NNRTI)-based in 15%, and integrase inhibitor (II)-based in 38%, while 24% of patients received other regimens. The SVR12 rate was 93.5% overall (95% confidence interval [CI]: 90.2-95.9), 93.3% (88.8-96.4) in patients with cirrhosis and 93.8% (88.1-97.3) in patients without cirrhosis. The SVR12 rates were 93.1% (84.5-97.7), 91.8% (80.4-97.7) and 95.8% (90.5-98.6) respectively, in patients receiving PI-based, NNRTI-based and II-based cART. In adjusted analysis, SVR12 was not associated with HIV RNA load, the cART regimen, cirrhosis, prior anti-HCV treatment, the duration of anti-HCV therapy, or ribavirin use. The most common adverse effects were fatigue and digestive disorders. CONCLUSIONS: New all-oral DAA regimens were well-tolerated and yielded high SVR12 rates in HIV/HCV-co-infected patients. LAY SUMMARY: We evaluated efficacy and safety of all-oral DAA regimens in a large French nationwide observational cohort study of HIV/HCV co-infected patients. Sustained virological response 12weeks after treatment cessation was 93.5% overall. The all-oral DAA regimens were well-tolerated and most common adverse effects were fatigue and digestive disorders.

All-oral Direct-acting Antiviral Regimens in HIV/Hepatitis C Virus-coinfected Patients With Cirrhosis Are Efficient and Safe: Real-life Results From the Prospective ANRS CO13-HEPAVIH Cohort.

BACKGROUND: Human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients with cirrhosis have long been considered to be difficult to treat, and real-life efficacy and tolerance data with all-oral direct-acting antiviral (DAA) combinations in these patients are scarce. METHODS: Cirrhotic HIV/HCV-coinfected patients enrolled in the French National Agency for Research on AIDS and Viral Hepatitis (ANRS) CO13 HEPAVIH cohort initiating an all-oral DAA regimen were consecutively included. A negative HCV RNA result at 12 weeks of follow-up or thereafter was assumed as a sustained virologic response (SVR12). Adjusted exact logistic regression was used to study factors associated with treatment outcome. RESULTS: We included 189 patients who initiated an all-oral DAA regimen with the following characteristics: median age 53.2 years; 74.6% male; Centers for Disease Control and Prevention classification A/B/C: 37%/31%/32%; Child-Pugh class A/B/C: 91%/8%/1%; 87% with HIV RNA <50 copies/mL; 99% on antiretrovirals; median CD4 count: 489 cells/µL; HCV treatment naive 29%; HCV genotype 1/2/3/4: 58%/4%/17%/21%. Sofosbuvir (SOF) + daclatasvir ± ribavirin (RBV) was used in 123 patients, SOF + RBV in 30, SOF + simeprevir in 11, and SOF + ledipasvir in 23. An SVR12 was reported in 93.1% of the patients (95% confidence interval, 88.5%-96.3%). In adjusted analyses, no difference was found between 12 or 24 weeks of treatment, in patients receiving RBV or not, and in treatment-naive vs experienced patients. Premature stop of DAA was reported for 8 patients. One patient died during treatment (unknown cause), and 12 other patients developed liver-related events. CONCLUSIONS: In this prospective real-life cohort, all-oral DAA regimens were well tolerated and associated with a high virologic efficacy in cirrhotic HIV/HCV-coinfected patients. This should not alleviate the surveillance for liver-related events in these patients.

First Occurrence of OXA-72-Producing Acinetobacter baumannii in Serbia.

Here, we characterized the first OXA-72-producing Acinetobacter baumannii isolate (designated MAL) recovered from a urine sample from a Serbian patient. Antimicrobial susceptibility testing, plasmid analysis, and whole-genome sequencing (WGS) were performed to fully characterize the resistome of the A. baumannii MAL clinical isolate. The isolate was multidrug resistant and remained susceptible only to colistin and tigecycline. PCR analysis revealed the presence of the carbapenemase OXA-72, an OXA-40 variant. Extraction by the Kieser method revealed the presence of two plasmids, and one of these, a ca. 10-kb plasmid, harbored the blaOXA-72 gene. WGS revealed 206 contigs corresponding to a genome of 3.9 Mbp in size with a G+C content of 38.8%. The isolate belonged to sequence type 492 and to worldwide clone II (WWCII). Naturally occurring ß-lactamase-encoding genes (blaADC-25 and blaOXA-66) were also identified. Aminoglycoside resistance genes encoding one aminoglycoside adenyltransferase (aadA2), three aminoglycoside phosphatases (strA, strB, aphA6), and one 16S RNA methylase (armA) conferring resistance to all aminoglycosides were identified. Resistance to fluoroquinolones was likely due to mutations in gyrA, parC, and parE Of note, the resistome matched perfectly with the antibiotic susceptibility testing results.

High Rate of Acquisition but Short Duration of Carriage of Multidrug-Resistant Enterobacteriaceae After Travel to the Tropics.

BACKGROUND: Multidrug-resistant Enterobacteriaceae (MRE) are widespread in the community, especially in tropical regions. Travelers are at risk of acquiring MRE in these regions, but the precise extent of the problem is not known. METHODS: From February 2012 to April 2013, travelers attending 6 international vaccination centers in the Paris area prior to traveling to tropical regions were asked to provide a fecal sample before and after their trip. Those found to have acquired MRE were asked to send fecal samples 1, 2, 3, 6, and 12 months after their return, or until MRE was no longer detected. The fecal relative abundance of MRE among all Enterobacteriaceae was determined in each carrier. RESULTS: Among 824 participating travelers, 574 provided fecal samples before and after travel and were not MRE carriers before departure. Of these, 292 (50.9%) acquired an average of 1.8 MRE. Three travelers (0.5%) acquired carbapenemase-producing Enterobacteriaceae. The acquisition rate was higher in Asia (142/196 [72.4%]) than in sub-Saharan Africa (93/195 [47.7%]) or Latin America (57/183 [31.1%]). MRE acquisition was associated with the type of travel, diarrhea, and exposure to ß-lactams during the travel. Three months after return, 4.7% of the travelers carried MRE. Carriage lasted longer in travelers returning from Asia and in travelers with a high relative abundance of MRE at return. CONCLUSIONS: MRE acquisition is very frequent among travelers to tropical regions. Travel to these regions should be considered a risk factor of MRE carriage during the first 3 months after return, but not beyond. CLINICAL TRIALS REGISTRATION: NCT01526187.

PegIFNα/ribavirin/protease inhibitor combination in severe hepatitis C virus-associated mixed cryoglobulinemia vasculitis.

BACKGROUND & AIMS: The aim of this study was to analyse the safety and efficacy of the PegIFNα/ribavirin/protease inhibitor combination in severe and/or refractory hepatitis C virus (HCV)-mixed cryoglobulinemia (MC) vasculitis. METHODS: This prospective cohort study included 30 patients (median age 59 years [53-66] and 57% of women) with HCV-MC vasculitis. PegIFNα/ribavirin (for 48 weeks) was associated with telaprevir (375 mg three times daily, for 12 weeks, [n = 17]) or boceprevir (800 mg three times daily, for 44 weeks, (n = 13]). RESULTS: Twenty three patients (76.7%) were non-responders to previous antiviral therapy. At week 72, twenty patients (66.7%) were complete clinical and sustained virological responders. The cryoglobulin level decreased from 0.45 to 0 g/L (p<0.0001) and the C4 level increased from 0.09 to 0.14 g/L (p = 0.017). Complete clinical responders had a higher frequency of purpura (16/20 [80%] vs. 4/10 [40%], p = 0.045), and a trend towards lower frequency of neuropathy (9/20 (45%) vs. 8/10 [80%], p = 0.12) compared with partial responders. Serious adverse events occurred in 14 patients (46.6%) during the 72 weeks of follow-up. Twenty eight patients (93.3%) received erythropoietin, 14 (46.6%) had red blood cell transfusion and 2 (6.6%) received granulocyte stimulating agent. The baseline factors associated with serious adverse events included liver fibrosis (p = 0.045) and a low platelet count (p = 0.021). CONCLUSIONS: The PegIFNα/ribavirin/protease inhibitor combination is highly effective in severe and/or refractory HCV-MC at the cost of frequent side effects. Baseline platelet count and liver fibrosis are useful in guiding treatment decisions.

Pharmacokinetic study of raltegravir in HIV-infected patients with end-stage liver disease: the LIVERAL-ANRS 148 study.

BACKGROUND: The end-stage LIVER disease and RALtegravir-Agence Nationale de Recherche sur le Sida et les hépatites (LIVERAL-ANRS) 148 study aimed to evaluate the safety, efficacy, and pharmacokinetic parameters of raltegravir (RAL) in human immunodeficiency virus (HIV)-infected patients with end-stage liver disease (ESLD) (substudy 1) and to assess the lack of pharmacokinetic interaction between RAL and the immunosuppressive regimen introduced after liver transplant (substudy 2). METHODS: All patients received 400 mg RAL twice daily plus 2 nucleoside reverse transcriptase inhibitors. Liver function and immunovirological parameters were monitored throughout the study. Serial blood samples were drawn to explore RAL pharmacokinetics. Plasma concentrations of protein unbound, total RAL, and RAL glucuronide were determined by liquid chromatography-tandem mass spectrometry. RESULTS: Ten patients with ESLD were analyzed in substudy 1. Despite an increased RAL exposure, RAL was well tolerated in all patients and no patient had to stop RAL therapy because of adverse events. Four patients were analyzed in substudy 2. No pharmacokinetic interaction was observed between cyclosporine, mycophenolic acid, and RAL. RAL tolerability was excellent; there were no episodes of acute rejection or opportunistic infection. HIV-RNA levels remained controlled and CD4 cell counts remained stable in all patients throughout the study. CONCLUSIONS: The results of the substudy 1 support RAL administration to patients with ESLD. Substudy 2 assesses the safety, tolerability, and efficacy of RAL therapy in HIV-infected patients after liver transplant. RAL might be recommended as a suitable antiretroviral therapy in HIV-infected patients undergoing liver transplant.

Telaprevir for HIV/hepatitis C virus-coinfected patients failing treatment with pegylated interferon/ribavirin (ANRS HC26 TelapreVIH): an open-label, single-arm, phase 2 trial.

BACKGROUND: Retreatment with pegylated interferon (peg-IFN) and ribavirin (RBV) results in poor sustained virological response (SVR) rates in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients. There are limited data regarding the use of telaprevir plus peg-IFN/RBV in this population. METHODS: HIV type 1-infected patients who previously failed ≥12 weeks of peg-IFN/RBV for HCV genotype 1 coinfection were enrolled in a single-arm, phase 2 trial. Patients with cirrhosis and previous null response were excluded. Authorized antiretrovirals were tenofovir, emtricitabine, efavirenz, atazanavir, and raltegravir. All patients received peg-IFN alfa-2a (180 µg/week) plus RBV (1000-1200 mg/day) for 4 weeks, followed by telaprevir (750 mg or 1125 mg every 8 hours with efavirenz) plus peg-IFN/RBV for 12 weeks and peg-IFN/RBV for 32-56 weeks according to virological response at week 8. The primary endpoint was the SVR rate at 24 weeks after the end of treatment (SVR24). RESULTS: Sixty-nine patients started treatment; SVR24 was achieved in 55 (80% [95% confidence interval, 68%-88%). SVR24 was not influenced by baseline fibrosis stage, IL28B genotype, antiretroviral regimen, HCV subtype, CD4 cell count, previous response to HCV treatment, HCV RNA level, or HCV RNA decline at week 4. HCV treatment was discontinued for adverse events (AEs) in 20% of patients, including cutaneous (4%), psychiatric (4%), hematological (6%), and other AEs (6%). Peg-IFN or RBV dose reduction was required in 23% and 43% of patients, respectively. Seventy percent of patients required erythropoietin, blood transfusions, or RBV dose reduction for anemia. Two patients died during the study. No HIV breakthrough was observed. CONCLUSIONS: Despite a high discontinuation rate related to toxicity, a substantial proportion of treatment-experienced HIV-coinfected patients achieved SVR24 with a telaprevir-based regimen.

Care of hepatitis C virus infection in France: modifications in three consecutive surveys between 1995 and 2010.

BACKGROUND & AIMS: To determine the characteristics of hepatitis C (HCV)- infected patients in 2010 and compare this survey with those reported in 1995 and 2001. PATIENTS AND METHODS: Observational multicentre study conducted in 2010 in French internal medicine, infectious diseases and hepatology departments. RESULTS: A total of 1621 HCV infected patients (mean age 50.1 ± 10.7 years; sex ratio M/F 1.8; genotype 1: 55.7%) were included. Of these, 910 (56.1%) were HIV­HCV co-infected, 463 (40.4%) were asymptomatic and 184 (16.1%) had cirrhosis at inclusion in this study. Positive viraemia was found in 1,025 patients (65.5%) at inclusion in this study. A complete pretreatment evaluation including investigation for HCV RNA, genotype determination and liver fibrosis was performed in 96.5, 80.5 and 68.7% of the 1,621 patients respectively. Previous and ongoing HCV treatments were noted in 49.6% and 20.1% of patients respectively. A sustained virological response (SVR) was observed in 271/801 (38.3%) patients, i.e. 44.1% and 30.7% in co-infected and mono-infected patients respectively. Cirrhosis was more frequent in the 2010 than in the 2001 and 1995 surveys (16.1% vs. 10.4% and 7.4% respectively; P < 0.0001). A complete pretreatment evaluation was performed in 57.9% and 50.9% of patients in 2010 and 2001 (P < 0.0001). Liver fibrosis evaluation was more frequent in 2010 than in the 2001 and 1995 surveys (68.7% vs. 62.7% and 28.7%, respectively, P < 0.0001). CONCLUSION: The care of HCV-infected patients has changed significantly in 'real life' through an improvement of pretreatment evaluation before the antiviral introduction and the increased use of antivirals. New HCV therapy combinations including protease inhibitors are warranted to increase the SVR rate.
