Résumé : International audience
Introduction. - Temocillin is an alternative to treat urinary tract infections with bacteria producing extended spectrum beta-lactamase (ESBL). The objective is to evaluate the use of temocillin in urinary tract infections. Materials and methods. - A systematic review of literature was carried out according to PRISMA criteria. All national and international recommendations have been reviewed regarding the indication of the use of temocillin in urology. Data collection on the use of temocillin in urinary tract infection has been performed from the Cochrane, LILACS and the Medline database. The following keywords were used: temocillin, extended spectrum. beta-lactamase, urinary tract infections, urine, prostate, epididymis, testis, diffusion, pharmacokinetics, pharmacodynamics. The selection was based on the methodology, language of publication (English/French), relevance to the topic and date of publication of the articles collected. The endpoint was to provide exhaustive scientific information allowing urologists to use this antibiotic in febrile urinary infections. Results. - Bacteria producing ESBL has a relatively high susceptible to temocillin, ranging from 61 % to 90 %. These rates would allow its use in probabilistic. The dosage recommended is currently, in the normo-renal patient, 4 g per day by intermittent infusion or continuously after a loading dose of 2g. Some studies argue, particularly in case of difficult clinical situations or obese patients, for administration of high doses (6 g/24 h) rather continuous infusion. There is no evident relationship between high doses and side effects. With an excellent urinary and prostatic diffusion, temocilllin might be recommend for the treatment of ESBL prostatitis. Conclusion. - Temocillin is known to have good urinary and prostatic diffusion. According to our results, this antibiotics is now a reliable alternative for the treatment of documented ESBL urinary tract infections. (C) 2017 Elsevier Masson SAS. All rights reserved.

Résumé : International audience
BACKGROUND: The male genital tract is suspected to constitute a viral sanctuary as persistent HIV shedding is found in the semen of a subset of HIV-infected men receiving effective antiretroviral therapy (HAART). The origin of this persistent shedding is currently unknown. Phylogenetic studies indicated that HIV in semen from untreated men arises from local sources and/or passive diffusion from the blood. We previously demonstrated in human and macaque low levels and localized infection of several semen-producing organs by HIV/SIV. Using a macaque model, this study investigates the impact of short term HAART (2-4 weeks) initiated either during the asymptomatic chronic stage or 4 h post-intravenous inoculation of SIVmac251 on the infection of male genital organs. METHODOLOGY/PRINCIPAL FINDINGS: Short term HAART during the chronic stage decreased blood viral load. No major impact of HAART was observed on SIV DNA levels in male genital organs using a sensitive nested PCR assay. Using in situ hybridization, SIV RNA+ cells were detected in all male genital tract organs from untreated and treated animals with undetectable blood viral load following HAART. Infected CD68+ myeloid cells and CD3+ T lymphocytes were detected pre- and post-HAART. In contrast, short term HAART initiated 4 h post-SIV exposure led to a drastic decrease of the male genital tissues infection, although it failed to prevent systemic infection. In both cases, HAART tended to decrease the number of CD3+ T cells in the male organs. CONCLUSIONS: Our results indicate that the established infection of male genital organs is not greatly impacted by short term HAART, whereas the same treatment during pre-acute phase of the infection efficiently impairs viral dissemination to the male genital tract. Further investigations are now needed to determine whether infection of male genital organs is responsible for long term persistent HIV shedding in semen despite HAART.

Résumé : International audience
AIM: To describe the main characteristics and the treatment of cryptococcosis in patients with sarcoidosis. DESIGN: Multicenter study including all patients notified at the French National Reference Center for Invasive Mycoses and Antifungals. METHODS: Retrospective chart review. Each case was compared with two controls without opportunistic infections. RESULTS: Eighteen cases of cryptococcosis complicating sarcoidosis were analyzed (13 men and 5 women). With 2749 cases of cryptococcosis registered in France during the inclusion period of this study, sarcoidosis accounted for 0.6% of all the cryptococcosis patients and for 2.9% of the cryptococcosis HIV-seronegative patients. Cryptococcosis and sarcoidosis were diagnosed concomitantly in four cases; while sarcoidosis was previously known in 14/18 patients, including 12 patients (67%) treated with steroids. The median rate of CD4 T cells was 145 per mm(3) (range: 55-1300) and not related to steroid treatment. Thirteen patients had cryptococcal meningitis (72%), three osteoarticular (17%) and four disseminated infections (22%). Sixteen patients (89%) presented a complete response to antifungal therapy. After a mean follow-up of 6 years, no death was attributable to cryptococcosis. Extra-thoracic sarcoidosis and steroids were independent risk factors of cryptococcosis in a logistic regression model adjusted with the sex of the patients. CONCLUSIONS: Cryptococcosis is a significant opportunistic infection during extra-thoracic sarcoidosis, which occurs in one-third of the cases in patients without any treatment; it is not associated to severe CD4 lymphocytopenia and has a good prognosis.

Résumé : International audience
Urinary tract infections are bacterial infections most commonly encountered in the community. The resistance rate of uropathogens to commonly prescribed antibiotics has increased worldwide but there are no published data concerning the resistance of strains isolated from community-acquired UTI in Guadeloupe. To assess the susceptibility patterns of Enterobacteriaceae strains isolated from outpatients in Guadeloupe we conducted a prospective study from December 2012 to May 2014 among outpatients consulting at private and public laboratories for urine analysis. Risk factors for E. coli resistance to amoxicillin, third-generation cephalosporin, and ciprofloxacin were also determined. To study the trends of E. coli resistance rates over the past 10 years, data on the susceptibility patterns of E. coli from 2003 to 2014 were also collected from three major laboratories for a retrospective study. During the prospective study, we isolated 1293 bacterial strains from the urine of outpatients presenting for urine analysis. The most commonly isolated bacteria were E. coli (57 %) and Klebsiella pneumoniae (15.5 %). Thirty seven per cent of the E. coli strains were resistant to amoxicillin. Resistance rates to third generation cephalosporin were low for E. coli and other Enterobacteriaceae (3.1 and 12.2 % respectively) and mostly due to the presence of an Extended Spectrum Beta-lactamase. Resistance to cotrimoxazole and ciprofloxacin was moderate (17.8 and 15.6 % respectively). However, the resistance rate of E. coli to ciprofloxacin has significantly increased during the last 10 years. Risk factors were consistent with previously reported data, especially for the increasing ciprofloxacin resistance with age. General practitioners in Guadeloupe need to be better informed to favor the prescription of fosfomycin-trometamol to reduce the risk of resistance to fluoroquinolones.

Résumé : International audience
A number of men receiving prolonged suppressive HAART still shed HIV in semen. To investigate whether this seminal shedding may be due to poor drug penetration and/or viral production by long-lived cells within male genital tissues, we analyzed semen and reproductive tissues from macaques chronically infected with SIVmac251 submitted to HAART for 4 months, intensified over the last seven weeks with an integrase inhibitor. We showed that a subset of treated animals continued shedding SIV in semen despite efficient HAART. This shedding was not associated with low antiretroviral drug concentrations in semen, or in testis, epididymis, seminal vesicles and prostate. HAART had no significant impact on SIV RNA in the urethra, whereas it drastically reduced SIV RNA levels in the prostate and vas deferens, and to a lesser extent in the epididymis and seminal vesicle. The only detectable SIV RNA positive cells within the male genital tract after HAART were urethral macrophages. SIV DNA levels in genital tissues were not decreased by HAART, suggesting the presence throughout the male genital tract of non-productively infected cells. In conclusion, our results demonstrate that 4 months of HAART induced variable and limited control of viral infection in the male reproductive organs, particularly the urethra, and suggest that infected long-lived cells in the male genital tract may be involved in persistent seminal shedding during HAART. These results pave the way for further investigations of male genital organs infection in long term treated infected individuals. A substantial subset of men receiving prolonged suppressive HAART in the blood still harbor HIV in semen, and cases of sexual transmission have been reported. To understand the origin of this persistence, we analyzed the semen and male reproductive tissues from SIV-infected macaques treated by HAART. We demonstrated that persistent seminal shedding was not linked to poor drug penetration in semen or semen-producing prostate, seminal vesicle, epididymis and testis. We revealed that HAART decreased SIV RNA to various extents in all male genital organs, with the exception of the urethra, in which SIV RNA+ macrophages were observed despite HAART. Importantly also, HAART did not impact SIV DNA levels in the male genital organs. These results suggest that infection of male genital organs, and particularly the urethra, could be involved in the release of virus in semen during HAART.

Résumé : International audience
Semen represents the main vector of HIV dissemination worldwide, yet the origin of HIV in semen remains unclear. Viral populations distinct from those found in blood have been observed in semen, indicating local viral replication within the male genital tract. The seminal vesicles, the secretions of which constitute more than 60% of the seminal fluid, could represent a major source of virus in semen. This study is the first to investigate the susceptibility of human seminal vesicles to HIV infection both in vitro and in vivo. We developed and characterized an organotypic culture of human seminal vesicles to test for target cells and HIV infection, and, in parallel, analyzed the seminal vesicle tissues from HIV-infected donors. In vitro, in contrast to HIV-1 X4, HIV-1 R5 exposure induced productive infection. Infected cells consisted primarily of resident CD163(+) macrophages, often located close to the lumen. In vivo, HIV protein and RNA were also detected primarily in seminal vesicle macrophages in seven of nine HIV-infected donors, some of whom were receiving prolonged suppressive highly active antiretroviral therapy. These results demonstrate that human seminal vesicles support HIV infection in vitro and in vivo and, therefore, have the potential to contribute virus to semen. The presence of infected cells in the seminal vesicles of treated men with undetectable viremia suggests that this organ could constitute a reservoir for HIV.

Résumé : International audience
Alveolar proteinosis (AP) is a rare disease characterized by alveolar accumulation of surfactant components, which impairs gas exchange. AP is classified into three groups: auto-immune AP defined by the presence of plasma autoantibodies anti-GM-CSF, the most frequent form (90 % of all AP); secondary AP, mainly occurring as a consequence of haematological diseases, or following on from toxic inhalation or infections, and genetic AP, which affects almost exclusively children. AP diagnosis is suspected where chest CT-scan demonstrates interstitial lung disease with a crazy paving aspect; and confirmed by bronchoalveolar lavage, which has a milky appearance and contains periodic acid Schiff positive proteinaceous alveolar deposits. The use of surgical lung biopsy to confirm AP is less frequent nowadays. In this context, positive antibodies against GM-CSF indicates an auto-immune etiology of the AP. Concerning management, whole lung lavage is the gold standard therapy. In refractory AP, new treatments are available such as subcutaneous or inhaled GM-CSF supplementation, or rituximab infusions. The clinical course is unpredictable. Spontaneous improvement or even cure can occur, and the 5-year actuarial survival is 95 %. The most frequent complications are infectious etiology.
La protéinose alvéolaire pulmonaire (PAP) est une maladie rare caractérisée par l’accumulation alvéolaire de composants du surfactant qui gêne les échanges gazeux. Les PAP sont séparées en trois groupes : les PAP auto-immunes caractérisées par la présence d’anticorps sériques anti-GM-CSF qui sont les plus fréquentes ; les PAP secondaires à une maladie sous-jacente, le plus souvent hématologique, mais aussi à l’inhalation de toxiques et à des infections ; enfin, les PAP d’origine génétique. Le diagnostic de PAP est évoqué sur le scanner thoracique avec une pneumopathie infiltrante diffuse ayant un aspect classique de crazy paving, puis confirmé par l’aspect laiteux du lavage bronchoalvéolaire, et la présence de matériel lipoprotéinacé PAS positif. La confirmation du diagnostic de PAP par biopsie pulmonaire chirurgicale est désormais rarement nécessaire. La positivité des anticorps sériques anti-GM-CSF signe le caractère auto-immun de la maladie. Le traitement de référence des PAP auto-immunes est le « grand lavage pulmonaire thérapeutique ». En cas de maladie réfractaire, d’autres traitements sont disponibles, tels que le GM-CSF en injection sous-cutanée ou en aérosol et le rituximab. L’évolution de la maladie est imprévisible. Une évolution spontanément favorable ou même une guérison spontanée peuvent survenir et la survie actuarielle à 5 ans est de 95 %. Les principales complications sont infectieuses.

Résumé : International audience
Although semen is the principal vector of human immunodeficiency virus (HIV) dissemination worldwide, the origin of the infected leukocytes and free viral particles in this body fluid remain elusive. Here we review the accumulated evidence of the genital origin of HIV in semen from therapy naive individuals and men receiving suppressive highly active antiretroviral therapy (HAART), summarize the data on the detection and localization of HIV/SIV within the male genital tract, discuss the potential involvement of each genital tissue as a source of infected cells and virions in semen in the absence and presence of HAART, and suggest further studies. Deciphering the exact sources of HIV in semen will be crucial to improving HIV transmission prevention strategies.

Résumé : International audience
Autostatic ureteral stents have been commonly used in urology for more than 20 years. Encrustation is a frequent and well described phenomenon that sometimes makes stent removal difficult. The main predisposing factors are: duration of stenting, history or concomitant stone disease, urinary tract infection or bacterial colonization, pregnancy and chemotherapy. Treatment depends on the degree of encrustation, especially when it involves the proximal loop. Extracorporeal lithotripsy alone or combined with endoscopic treatment is very effective, but open surgery may sometimes be necessary. The authors report a case in which drainage was exceptionally prolonged as the stent was removed after a period of 10 years. Stent removal required 3 operations, including one open procedure. The steps of treatment are described and the aetiologies of encrustation and the therapeutic strategy are discussed.

Résumé : International audience
Parapneumonic pleural effusions represent the main cause of pleural infections. Their incidence is constantly increasing. Although by definition they are considered to be a “parapneumonic” phenomenon, the microbial epidemiology of these effusions differs from pneumonia with a higher prevalence of anaerobic bacteria. The first thoracentesis is the most important diagnostic stage because it allows for a distinction between complicated and non-complicated parapneumonic effusions. Only complicated parapneumonic effusions need to be drained. Therapeutic evacuation modalities include repeated therapeutic thoracentesis, chest tube drainage or thoracic surgery. The choice of the first-line evacuation treatment is still controversial and there are few prospective controlled studies. The effectiveness of fibrinolytic agents is not established except when they are combined with DNase. Antibiotics are mandatory; they should be initiated as quickly as possible and should be active against anaerobic bacteria except for in the context of pneumococcal infections. There are few data on the use of chest physiotherapy, which remains widely used. Mortality is still high and is influenced by underlying comorbidities.
Les épanchements pleuraux parapneumoniques représentent la principale étiologie des pleurésies infectieuses. Leur incidence est en constante augmentation. Bien qu’ils soient qualifiés de « parapneumoniques », l’épidémiologie microbienne est différente de celle des pneumonies avec notamment une plus grande fréquence des germes anaérobies. La ponction pleurale exploratrice représente l’étape diagnostique centrale qui permet de distinguer les épanchements parapneumoniques compliqués et non compliqués. Seuls les épanchements parapneumoniques compliqués doivent faire l’objet d’un traitement évacuateur reposant sur la mise en œuvre de ponctions pleurales répétées (PPR), d’un drainage thoracique ou d’une prise en charge chirurgicale. Le choix de la technique évacuatrice première reste débattu car il existe peu d’études prospectives comparatives. L’utilisation d’agents fibrinolytiques n’a pas fait la preuve de son efficacité sauf lorsqu’ils sont utilisés en association à la DNAse. L’antibiothérapie doit être systématique, précoce et couvrir les germes anaérobies, sauf en cas d’infection à pneumocoque. Il existe peu de données sur la place de la kinésithérapie qui reste largement utilisée. La mortalité est élevée et directement influencée par les comorbidités sous-jacentes.

Résumé : International audience
Much research is being carried out into indoor exposure to harmful agents. This review focused on the impact on children's health, taking a broad approach to the indoor environment and including chemical, microbial, physical and social aspects. Papers published from 2006 onwards were reviewed, with regards to scientific context. Most of publications dealt with chemical exposure. Apart from the ongoing issue of combustion by-products, most of these papers concerned semi volatile organic compounds (such as phthalates). These may be associated with neurotoxic, reprotoxic or respiratory effects and may, therefore, be of particular interest so far as children are concerned. In a lesser extent, volatile organic compounds (such as aldehydes) that have mainly respiratory effects are still studied. Assessing exposure to metals is still of concern, with increasing interest in bioaccessibility. Most of the papers on microbial exposure focused on respiratory tract infections, especially asthma linked to allergens and bio-aerosols. Physical exposure includes noise and electromagnetic fields, and articles dealt with the auditory and non auditory effects of noise. Articles on radiofrequency electromagnetic fields mainly concerned questions about non-thermal effects and papers on extremely low-frequency magnetic fields focused on the characterization of exposure. The impact of the indoor environment on children's health cannot be assessed merely by considering the effect of these different types of exposure: this review highlights new findings and also discusses the interactions between agents in indoor environments and also with social aspects.

Résumé : International audience
There appears to be an incompressible high rate of preterm births among populations of African origin irrespective of their geographic location. The objective of this study was to assess the risk factors for preterm birth in a French Caribbean population of African descent, offered medical care comparable to that on the French mainland, but presenting a higher rate of preterm birth. The study was based on a birth cohort at maternity hospitals in Guadeloupe (French West Indies) including 911 singleton pregnancies enrolled during their third trimester check-up visits. Associations between risk factors and the risk of preterm delivery (spontaneous and induced) were assessed using a multivariate Cox model. In addition, prevalences of sociodemographic and medical factors in Guadeloupe were compared with those on the French mainland. 144 women (15.8 %) delivered preterm, medically induced in 52 %. Women delivering preterm were more often over 35 years old (37 %), single (54 %), and had higher prevalence of prior preterm birth (20 %), prior miscarriage (37 %), lupus (3 %), asthma (14 %), gestational hypertension (26 %), gestational diabetes (13 %) and urinary tract infection (24 %) than women with term births. In the whole cohort, these risk factors were also more frequent than in mainland France. Our results suggest highly prevalent medical risk factors for preterm births in Guadeloupe. This observation combined with specific social risk factors (older maternal age, single living) less frequent on the French mainland probably explains a large part of a higher prevalence of preterm births in this population despite similar medical provision.

Résumé : International audience
The underlying cause of morbidity in cystic fibrosis (CF) is the decline in lung function, which results in part from chronic inflammation. Inflammation and infection occur early in infancy in CF and the role of innate immune defense in CF has been highlighted in the last years. Once thought simply to be consumers of bacteria, macrophages have emerged as highly sensitive immune cells that are located at the balance point between inflammation and resolution of this inflammation in CF pathophysiology. In order to assess the potential role of macrophage in CF, we review the evidence that: (1) CF macrophage has a dysregulated inflammatory phenotype; (2) CF macrophage presents altered phagocytosis capacity and bacterial killing; and (3) lipid disorders in CF macrophage affect its function. These alterations of macrophage weaken innate defense of CF patients and may be involved in CF disease progression and lung damage.

Résumé : International audience
Background: Mounier-Kuhn syndrome (MKS) is a rare disorder characterized by enlargement of the trachea and main bronchi and associated with recurrent respiratory tract infections. Objective: This multicenter, retrospective study was carried out to describe respiratory conditions associated with tracheobronchomegaly. Methods: Nine institutions involved in the ‘Groupe d'Endoscopie de Langue Française' (GELF) participated in this study. A standard form was used to record patient characteristics, treatments and follow-up from medical charts. Results: Seventeen patients, 53% male, aged 58 ± 18 years at diagnosis were included. Recurrent infections revealed MKS in 88% of cases. Main comorbid conditions were diffuse bronchiectasis in 88% of patients and tracheobronchomalacia in 67% of cases. The exacerbation rate was 1.5 exacerbations/patient/year. The main non-respiratory morbid condition was gastroesophageal reflux disease in 29% of cases. Interventional bronchoscopy was performed in seven patients (41%), consisting of laser (n = 2) and tracheal stenting (n = 5). Complications related to stents were observed in 80% of cases with a mean stent duration of 8 months. Four deaths, including three due to respiratory causes, occurred during follow-up. Conclusions: This is the largest series of MKS reported in the literature, showing that bronchiectasis and tracheobronchomalacia are the main associated morbid conditions that constitute a challenge for treatment.
