Abstract
Whipple disease is an infection caused by the bacterium Tropheryma whipplei. Due to its unspecific clinical symptoms, it is difficult to diagnose and often remains undetected for a long time. The case of a patient who presented with acute intestinal symptoms to the authors' department is reported. The diagnosis of classic Whipple disease was established. The symptoms subsided under antibiotic therapy. Complications in the form of immune reconstitution inflammatory syndrome (IRIS) occurred, requiring immunosuppressive treatment.

Clinical efficacy of chloroquine derivatives in COVID-19 infection: comparative meta-analysis between the big data and the real world. New Microbes New Infect 2020; 38:100709. [PMID: 33088574 PMCID: PMC7558783 DOI: 10.1016/j.nmni.2020.100709] [Citation(s) in RCA: 53] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 05/28/2020] [Accepted: 06/04/2020] [Indexed: 12/23/2022] Open
Abstract
In the context of the current coronavirus disease 2019 (COVID-19) pandemic, we conducted a meta-analysis on the effects of chloroquine derivatives in patients, based on unpublished and published reports available publicly on the internet as of 27 May 2020. The keywords 'hydroxychloroquine', 'chloroquine', 'coronavirus', 'COVID-19' and 'SARS-Cov-2' were used in the PubMed, Google Scholar and Google search engines without any restrictions as to date or language. Twenty studies were identified involving 105 040 patients (19 270 treated patients) from nine countries (Brazil, China, France, Iran, Saudi Arabia, South Korea, Spain and the USA). Big data observational studies were associated with conflict of interest, lack of treatment dosage and duration, and absence of favourable outcome. Clinical studies were associated with favourable outcomes and details on therapy. Among clinical studies, three of four randomized controlled trials reported a significant favourable effect. Among clinical studies, a significant favourable summary effect was observed for duration of cough (OR 0.19, p 0.00003), duration of fever (OR 0.11, p 0.039), clinical cure (OR 0.21, p 0.0495), death (OR 0.32, p 4.1 × 10-6) and viral shedding (OR 0.43, p 0.031). A trend for a favourable effect was noted for the outcome 'death and/or intensive care unit transfer' (OR 0.29, p 0.069) with a point estimate remarkably similar to that observed for death (∼0.3). In conclusion, a meta-analysis of publicly available clinical reports demonstrates that chloroquine derivatives are effective to improve clinical and virological outcomes, but, more importantly, they reduce mortality by a factor of 3 in patients with COVID-19. Big data are lacking basic treatment definitions and are linked to conflict of interest. The retraction of the only big data study associated with a significantly deleterious effect the day after (June 5, 2020) the acceptance of the present work (June 4, 2020) confirms the relevance of this work.

Abstract
Use of peripheral venous catheters (PVCs) is very common in hospitals. According to the literature, after a visit to the emergency department >75% of hospitalised patients carry a PVC, among which almost 50% are useless. In this study, the presence and complications of PVCs in an infectious diseases (ID) unit of a French tertiary-care university hospital were monitored. A total of 614 patients were prospectively included over a 6-month period. Among the 614 patients, 509 (82.9%) arrived in the ID unit with a PVC, of which 260 (51.1%) were judged unnecessary and were removed as soon as the patients were examined by the ID team. More than one-half of PVCs were removed within 24 h in the unit (308/509; 60.5%). PVCs were complicated for 65 (12.8%) of the 509 patients, with complications including extravasation, cutaneous necrosis, lymphangitis, phlebitis, tearing off the patient, superficial venous thrombosis and arthritis. We must therefore continue to search for unjustified PVC insertion. Alternatives to the intravenous administration route must be proposed, such as subcutaneous infusion or oral antibiotic therapy.

Abstract
Fecal microbiota transplantation (FMT) is the process by which fecal microbiota are donated from a healthy individual and subsequently transplanted into a diseased or young individual. The mechanism by which FMT is effective is believed to be due to enhanced beneficial microbes, increased microbiome diversity, and restored normal flora. Beneficial gut microorganisms not only play a role in maintaining an intestinal barrier and metabolizing nutrients, but importantly, these microbes help regulate local and systemic immune function. Although FMT has been described for several centuries, only recently has it been utilized as a mainstream therapy in humans and significantly considered for applications in other species. In humans and animals, gastrointestinal diseases are by far the most widely accepted FMT-treatable conditions; however, recent research has shown exceptional promise for FMT being used to treat or prevent other conditions, including those outside of the gastrointestinal tract. Overall, FMT is likely an underutilized, widely-available, and inexpensive tool for improving the health and response to disease in animals. In this review, the effects of FMT on veterinary diseases and potential applications for FMT in animals are discussed.

Factors associated with unfavorable outcome in a multicenter audit of 100 infective endocarditis. Eur J Clin Microbiol Infect Dis 2018; 38:109-115.

Abstract
We aimed to identify factors associated with unfavorable outcome in patients treated for infective endocarditis (IE), with a focus on departure from European guidelines. We conducted a retrospective audit of all adult patients treated for endocarditis during a 1-year period across a regional network of nine care centers in the south-east of France. Medical records were reviewed regarding patient and infection characteristics, antibiotic therapy, outcome, and compliance to the European Society of Cardiology guidelines. Antibiotic treatment appropriateness was evaluated regarding molecule, dosage, and duration, according to guidelines. Primary endpoint was the assessment of factors associated with unfavorable outcome, defined as in-hospital mortality or IE relapse at 1-year follow-up. Secondary endpoints were intensive care admission, iatrogenic events, and nosocomial infections that occurred during hospital stay. One hundred patients were included. Median age was 71 years old. Twenty-two patients died and IE relapse occurred in two patients, representing 24 patients with unfavorable outcome. Overall, antibiotic treatment was deemed appropriate in 28 cases. Thirty-three patients required intensive care, 34 iatrogenic events were found, including 19 acute kidney injuries, and 13 nosocomial infections occurred during care. Using a logistic regression, factors associated with unfavorable outcome were admission in the intensive care unit (adjusted odd ratio 7.26 [1.8-29.28]; p = 0.005), new-onset nosocomial infection (adjusted odd ratio 8.83 [1.42-54.6]; p = 0.019), and age > 71 years old (adjusted odd ratio 11.2 [2.76-46.17]; p < 0.001). Departure from guidelines was frequent but not related to unfavorable outcome in our study. Only intensive care, age, and nosocomial infections were associated with mortality and relapse. Iatrogenic events were numerous, with no impact on outcome.

Abstract
In 2009, the European Centre for Disease Prevention and Control (ECDC) estimated that multidrug-resistant (MDR) bacterial infections were responsible for 25,000 extra-deaths per year. In 2015, another report estimated that 12,500 extra-deaths were attributable to MDR bacteria every year in France. Recently, the United Nations claimed that resistance to antimicrobials was a global scourge, forecasting 10 million deaths in 2050. Surprisingly, our antibiotic resistance surveillance system in Marseille, France, did not allowed us to observe similar trends. We herein compared our data on extremely drug-resistant (XDR)/pandrug-resistant (PDR) patient extra-deaths to evaluations and predictions from these reports. First, we retrospectively collect and analyze antibiotic resistance data produced by our settings between November 2009 and March 2015 to look for 30-day deaths attributable to XDR/PDR strains belonging to 11 bacterial species/genus. In parallel, we performed a PubMed literature search to look for articles published prior to July 2016 and describing human deaths due to PDR strains. Overall, 35,723 patients were infected by at least one bacterial species/genus of interest and 85 by XDR/PDR strains. Of these patients, only one death was attributable to a XDR bacterial infection in a patient with strong comorbidities and two consecutive septic shocks. Our literature review shows that only four articles described human deaths due to PDR bacteria. All together, these data allowed us to conclude that there is a large discrepancy between the real count of deaths attributable to XDR/PDR bacteria and alarmist predictions.

Abstract
Infective endocarditis (IE) can be diagnosed using the Duke criteria, which cannot be conclusive especially when the results of blood cultures are negative. This study aimed at using real-time polymerase chain reaction (PCR) technique to isolate bacteria present in whole blood samples of patients with definitive IE on the basis of the method designed in this study. This laboratory and test study was conducted on 20 whole blood samples taken from patients with definitive IE. Real-time PCR of the 16s rRNA was utilized to directly analyze whole blood samples to diagnose bacterial IE. Of 20 whole blood samples with definitive IE, only one blood culture (5%) was positive and the isolated bacterium belonged to Streptococci viridans group. Also, 13 whole blood samples were positive using real-time PCR technique. The isolated bacteria were Enterococcus faecalis with seven (35%) cases, Streptococcus gallolyticus with two (10%) cases, Streptococcus mutans with one (5%) case, Streptococcus sanguinis with one (5%) case, Streptococcus salivarius with one (5%) case, and Staphylococcus aureus with one (5%) case. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) using real-time PCR technique were 65%, 100%, 100%, and 74%, respectively. The developed real-time PCR method allows us to detect bacteria in whole blood samples and is much more sensitive than culturing method. It also permits the differentiation of the main group of bacteria within a few hours for IE.
