Fatal Cowpox Virus Infection in Human Fetus, France, 2017.

Cowpox virus (CPXV) has an animal reservoir and is typically transmitted to humans by contact with infected animals. In 2017, CPXV infection of a pregnant woman in France led to the death of her fetus. Fetal death after maternal orthopoxvirus (smallpox) vaccination has been reported; however, this patient had not been vaccinated. Investigation of the patient's domestic animals failed to demonstrate prevalence of CPXV infection among them. The patient's diagnosis was confirmed by identifying CPXV DNA in all fetal and maternal biopsy samples and infectious CPXV in biopsy but not plasma samples. This case of fetal death highlights the risk for complications of orthopoxvirus infection during pregnancy. Among orthopoxviruses, fetal infection has been reported for variola virus and vaccinia virus; our findings suggest that CPXV poses the same threats for infection complications as vaccinia virus.

Clostridium haemolyticum Infection: A Cause of Hemolytic Anemia in a Patient with Bone Marrow Necrosis.

Clostridium haemolyticum is a sporulating Gram-positive anaerobic rod that is considered to be one of the most fastidious and oxygen-sensitive anaerobes. It is a well-known animal pathogen and the cause of bacillary hemoglobinuria primarily in cattle. To date, human infections caused by C. haemolyticum have been reported in three patients with malignant underlying diseases. We present herein the case of a 30-year-old obese woman with no significant past medical history who developed bacteremia caused by C. haemolyticum with massive intravascular hemolysis associated with bone marrow necrosis and acute renal failure. Because of subculture failure, the diagnosis was made on the basis of 16S rDNA sequencing and next-generation sequencing. The patient, who had been afebrile for 20 days after a 17-day-course of antibiotics, experienced a second bacteremic episode caused by C. haemolyticum. After having been successfully treated for 42 days with clindamycin and amoxicillin-clavulanic acid, the patient developed acute myeloid leukemia as a result of bone marrow regeneration. Although uncommon in humans, infections caused by C. haemolyticum are severe and should be considered in a febrile patient who has severe hemolytic anemia. This case also highlights the importance of using molecular techniques for the identification of this fastidious anaerobic organism.

Rapid antigen test use for the management of group A streptococcal pharyngitis in community pharmacies.

Despite group A streptococci being an infrequent cause of pharyngitis in adult outpatients, sore throat remains a common indication for antibiotic prescription. This prospective multicentre non-randomised study describes a community pharmacy-based antimicrobial stewardship intervention consisting in the implementation of rapid antigen testing (RAT) for the management of adults with sore throat. Trained pharmacists triaged patients presenting with symptoms of pharyngitis using the modified Centor score. Those at risk for streptococcal infection were tested with RAT. Patients with a positive RAT were invited to consult a physician, whereas others were offered a symptomatic treatment. All patients received educational leaflets and were asked to fill in a follow-up form 7 days later. Ninety-eight pharmacies in one French region participated, and 559 patients were included over 6 months. RAT was proposed in 367 (65.7%) cases, and it was positive in 28 (8.3%). The follow-up form was returned by 140 (38.5%) participants. Of these, 10/10 patients with positive RAT further consulted a physician and were prescribed an antibiotic treatment, whereas 96.5% (110/114) of patients with negative results and not having any other reason to seek for doctor's advice did not consult. All participants found the intervention useful. Pharmacists spent 6-15 min to perform the intervention, and 98.6% (73/74) of pharmacists giving a feedback declared to be ready to implement this intervention in daily practice, if endorsed and reimbursed. Our results suggest that a pharmacy-based programme for the management of sore throat is feasible and could increase adherence to guidelines.

Impact of selective reporting of antibiotic susceptibility test results on the appropriateness of antibiotics chosen by French general practitioners in urinary tract infections: a randomised controlled case-vignette study.

Selective reporting of antibiotic susceptibility test (AST) results is a potential intervention for laboratory-based antibiotic stewardship. The aim of this study was to assess the impact of AST reporting on the appropriateness of antibiotics selected by French general practitioners for urinary tract infections (UTIs). A randomised controlled case-vignette study in a region of northeast France surveyed general practitioners between July and October 2015 on treatment of four clinical cases of community-acquired Escherichia coli UTIs (two cases of complicated cystitis, one of acute pyelonephritis and one male UTI). In Group A, selective reporting of AST results was used for the first two cases and complete reporting for the other two cases; these were reversed in Group B. The overall participation rate was 131/198 (66.2%). Provision of selective AST results significantly increased the rate of adherence to national guidelines for first-line antibiotic treatment in Cases 1, 3 and 4 by 22.4% (55.2% vs. 32.8%, P = 0.01), 67.5% (75.0% vs. 7.5%, P <0.001) and 36.3% (45.3% vs. 9.0%, P <0.001), respectively. The improvement in compliance was not significant for Case 2. Prescriptions of amoxicillin-clavulanic acid, fluoroquinolones and cephalosporins decreased by 25.0% to 45.0%, depending on the clinical vignette. Most (106/131, 81.0%) participants favoured the routine use of selective reporting of AST results. In conclusion, selective reporting of AST results seems to improve antibiotic prescribing practices in primary care, and may be considered a key element of antimicrobial stewardship programmes.

Cancer-Related Causes of Death among HIV-Infected Patients in France in 2010: Evolution since 2000.

OBJECTIVES: The current study aimed at describing the distribution and characteristics of malignancy related deaths in human immunodeficiency virus (HIV) infected patients in 2010 and at comparing them to those obtained in 2000 and 2005. METHODS: Data were obtained from three national surveys conducted in France in 2010, 2005 and 2000. The underlying cause of death was documented using a standardized questionnaire fulfilled in French hospital wards involved in the management of HIV infection. RESULTS: Among the 728 deaths reported in 2010, 262 were cancer-related (36%). After a significant increase from 28% in 2000 to 33% in 2005 and 36% in 2010, cancers represent the leading cause of mortality in HIV infected patients. The proportion of deaths attributed to non-AIDS/non-hepatitis-related cancers significantly increased from 2000 to 2010 (11% of the deaths in 2000, 17% in 2005 and 22% in 2010, p<0.001), while those attributed to AIDS-defining cancers decreased during the same period (16% in 2000, 13% in 2005 and 9% in 2010, p = 0.024). Particularly, the proportion of respiratory cancers significantly increased from 5% in 2000 to 6% in 2005 and 11% in 2010 (p = 0.004). Lung cancer was the most common cancer-related cause of death in 2010 (instead of non-Hodgkin lymphoma so far) and represented the leading cause of death in people living with HIV overall. CONCLUSIONS: Cancer prevention (especially smoking cessation), screening strategies and therapeutic management need to be optimized in HIV-infected patients in order to reduce mortality, particularly in the field of respiratory cancers.

Causes of death among HIV-infected patients in France in 2010 (national survey): trends since 2000.

OBJECTIVE: The Mortalité 2010 survey aimed at describing the causes of death among HIV-infected patients in France in 2010 and their evolution since 2000. DESIGN AND METHODS: A national sample of clinical sites, providing HIV care and treatment, notified and documented deaths using a standardized questionnaire. RESULTS: The 90 participating wards notified 728 deaths. Median age at death was 50 years (interquartile range 45-58) and 75% were men. The main underlying causes of death were AIDS-related (25% in 2010 vs. 36% in 2005 and 47% in 2000), non-AIDS non-viral hepatitis-related malignancy (22 vs. 17 and 11%), liver-related (11 vs. 15 and 13%), cardiovascular diseases (10 vs. 8 and 7%) and non-AIDS-related infections (9 vs. 4 and 7%). Malignancies (AIDS and non-AIDS-related) accounted for a third of all causes of death. AIDS accounted for 33% of all causes of death among patients mono-infected with HIV vs. only 13% among those co-infected with hepatitis B virus or hepatitis C virus. CONCLUSION: In 2010, 25% of the causes of death among HIV-infected patients remained AIDS-related. Improved screening and earlier HIV treatment should lead to a smaller proportion of deaths due to AIDS. The majority of patients died of various causes, whereas their HIV infection was well controlled under treatment. Improving case management of HIV-infected patients should include a multidisciplinary approach (prevention, screening, treatment), especially in oncology. Smoking cessation should be a priority goal.

Primary cerebral alveolar echinococcosis: mycology to the rescue.

A case of primary cerebral alveolar echinococcosis with a favorable outcome is reported. A universal fungal PCR enabled this diagnosis, while the initial serological analysis remained noncontributive.

Value of HIV patients with regular follow-up as in-house internal controls of flow cytometry measurement of lymphocyte subsets.

BACKGROUND: Quality assessment in flow cytometry cannot obey the same rules as those applicable to the measurement of chemical analytes. However, regular follow-up of known patients may provide a robust in-house control of cell subsets evaluation. METHODS: Sequential blood samples assessed for 32 HIV patients over several years and showing good stability were retrospectively assessed to establish coefficient of variations of the percentages of CD3+, CD4+, CD8+ cells, and CD4+ absolute counts (ACs). RESULTS: Mean relative standard variations for the whole cohort were of 0.04, 0.14, 0.08, and 0.18 for CD3%, CD4%, CD8%, and CD4 ACs, respectively. DISCUSSION: In-house follow-up of regularly checked compliant patients is a good alternative to traditional and costly repeatability and reproducibility studies for the validation of routine flow cytometry. © 2013 International Clinical Cytometry Society.

Characterization of a new blaOXA-48-carrying plasmid in Enterobacteriaceae.

In this work, we characterized a new, 160-kb, blaOXA-48-harboring IncL/M-type plasmid isolated from a Klebsiella pneumoniae strain from France. Moreover, we report the transfer of a 60-kb OXA-48-encoding plasmid from Klebsiella pneumoniae to other Enterobacteriaceae in two patients.

Is total community viral load a robust predictive marker of the efficacy of the TasP strategy?

A mild but significant association between a decrease in the total community viral load (CVL) and a decrease in the number of new HIV diagnoses was observed between 2005 and 2010 in the population of northern and eastern France. This result suggests that CVL could be used as robust marker of the efficacy of the "Treatment as Prevention" strategy, and it may even be stronger if a large number of undiagnosed patients and early HIV infection cases indicated by extend screening are included in the CVL measurement.

Relevance of fluoroquinolone use in hospitals in the Lorraine region of France before and after corrective measures: an investigation by the Antibiolor Network.

OBJECTIVES: This study of fluoroquinolone use was carried out before and after an educational intervention run by Antibiolor, a regional network to all hospitals in the Lorraine region of France. METHODS: The relevance of fluoroquinolone prescription according to regional guidelines was assessed using a standard card filled out by physicians and pharmacists at the voluntarily participating hospitals. A therapeutic index of adequacy was established for each card. The initial survey took place in January 2008, with feedback and proposals for corrective measures in January 2009. The second survey was organized in June 2009. The results of the 2 surveys were compared. RESULTS: Twenty-four hospitals completed a total of 1336 cards in the first survey (S1) and 944 cards in the second (S2). The appropriateness of indications for fluoroquinolone use improved by 57% between the 2 surveys. All the criteria analyzed (choice of drug, dosage, treatment duration) were significantly improved in S2 compared to S1, as was the adequacy index (70% improvement). CONCLUSIONS: In view of the consequences of fluoroquinolone use, many hospitals in Lorraine were keen to participate in this study, confirming its feasibility over a large area. In view of the study results, the book of guidelines was re-examined and republished at the conclusion of S2. Greater adherence to guidelines was noted in S2, demonstrating the benefit of assessing the situation thoroughly before proposing corrective measures and evaluating their impact.

Control of a regional outbreak of vanA glycopeptide-resistant Enterococcus faecium, Eastern France, 2004-2009.

At the end of 2004, an outbreak of glycopeptide-resistant enterococci (GRE) spread from the Nancy Teaching Hospital to more than 40 facilities in the Lorraine region. Because this outbreak appeared to be uninhibited, a regional task force was set up to organize and co-ordinate the management of the outbreak, visiting the affected facilities to publicize the existing recommendations and take stock of the problems encountered in the field. The task force then proposed control measures specific to the region. The proposed measures included promoting the use of alcohol-based hand-rub solutions, isolation measures, enhanced screening policies, cohorting GRE-colonized patients and contacts in special wards with dedicated staff where possible, or failing that, isolating them in single rooms with additional "contact" precautions, maintaining these precautions for GRE-colonized patients until a negative stool sample was obtained after antibiotic treatment (which is a more restrictive definition of "cleared" than usually employed), regional co-ordination of the follow-up of GRE-colonized patients with the weekly publication of a list of institutions that were or had been affected to allow isolation measures to be adopted as soon as known-GRE-colonized patient were readmitted. It was not possible to determine the efficacy of each individual measure on the course of the outbreak. Nevertheless, we observed that the number of new GRE-colonized patients started to decrease following their implementation. Ultimately, 1077 GRE colonizations were recorded in Lorraine, and the outbreak is now under control.

Evaluation of the duration of vanA vancomycin-resistant Enterococcus faecium carriage and clearance during a large-scale outbreak in a region of eastern France.

A monthly follow-up evaluation of vancomycin-resistant Enterococcus-colonized patients conducted during an outbreak in France revealed that carriage can persist for an extended period. Recurrence was observed despite as many as 3 negative cultures. As a result, we propose another definition for VRE clearance.

Probiotics and intestinal colonization by vancomycin-resistant enterococci in mice and humans.

We investigated the impact of probiotics on the intestinal carriage of vancomycin-resistant enterococci (VRE). Administration of Lactobacillus rhamnosus Lcr35 but not Escherichia coli Nissle reduced, although not significantly, the density of VRE colonization in a murine model. No effect of Lcr35 was observed in a double-blind placebo randomized study, involving nine patients.
