Kaposi sarcoma among people living with HIV in the French DAT'AIDS cohort between 2010 and 2015.

BACKGROUND: Although antiretroviral therapy (ART) has reduced the risk of Kaposi sarcoma (KS), KS cases still occur in HIV-infected people. OBJECTIVE: To describe all KS cases observed between 2010 and 2015 in a country with high ART coverage. METHODS: Retrospective study using longitudinal data from 44 642 patients in the French Dat'AIDS multicenter cohort. Patients' characteristics were described at KS diagnosis according to ART exposure and to HIV-plasma viral load (HIV-pVL) (≤50 or >50) copies/mL. RESULTS: Among the 209 KS cases diagnosed during the study period, 33.2% occurred in ART naïve patients, 17.3% in ART-experienced patients and 49.5% in patients on ART, of whom 23% for more than 6 months. Among these patients, 24 (11.5%) had HIV-pVL ≤50 cp/mL, and 16 (66%) were treated with a boosted-PI-based regimen. The distribution of KS localization did not differ by ART status nor by year of diagnosis. LIMITATIONS: Data on human herpesvirus 8, treatment modalities for KS and response rate were not collected. CONCLUSION: Half of KS cases observed in the study period occurred in patients not on ART, reflecting the persistence of late HIV diagnosis. Factors associated with KS in patients on ART with HIV-pVL ≤50 cp/mL remain to be explored.

Missed opportunities of HIV pre-exposure prophylaxis in France: a retrospective analysis in the French DAT'AIDS cohort.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) was implemented in France in November 2015 based on individual-level risk factors for HIV infection. We evaluated the proportion of missed opportunities for PrEP among newly HIV-diagnosed people entering the Dat'AIDS cohort in 2016. METHODS: Multicenter retrospective analysis in 15 French HIV clinical centers of patients with a new diagnosis of HIV infection. Among them we differentiated patients according to the estimated date of infection: those occurring in the PrEP area (a previous negative HIV test in the last 12 months or those with an incomplete HIV-1 western blot (WB) with no HIV-1 anti-Pol-antibody at time of HIV diagnosis) and those in the pre-PrEP area (older infections). Epidemiological, biological and clinical data at HIV diagnosis were collected. Clinicians retrospectively identified potential eligibility for PrEP based on individual-level risk factors for HIV infection among those infected in the PrEP area. RESULTS: Among 966 patients with a new HIV diagnosis, 225 (23.3%) were infected in the PrEP area and 121 (53.8%) had complete data allowing evaluation of PrEP eligibility. Among them, 110 (91%) would have been eligible for PrEP, median age 31 years, with 68 (75.6%) born in France and 10 (11.1%) in Central/West Africa, with more than one previous STI in 19 (15.7%). The main eligibility criteria for PrEP were being a man who had sex with men or transgender 91 (82.7%) with at least one of the following criteria: unprotected anal sex with ≥2 partners in the last 6 months: 67 (60.9%); bacterial sexually transmitted infection in the last 12 months: 33 (30%); Use of psychoactive substances in a sexual context (chemsex): 16 (14.5%). PrEP was indicated for other HIV risk factors in 25 (22.7%). CONCLUSION: With 91% (110/121) of patients infected in the PrEP area eligible for PrEP, this study highlights the high potential of PrEP in avoiding new infection in France but also shows a persistent delay in HIV testing. Thus, an important limit on PrEP implementation in France could be insufficient screening and care access.

Psychiatric and substance use disorders in HIV/hepatitis C virus (HCV)-coinfected patients: does HCV clearance matter? [Agence Nationale de Recherche sur le SIDA et les Hépatites Virales (ANRS) HEPAVIH CO13 cohort].

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.

Indicators show differences in antibiotic use between general practitioners and paediatricians.

The purpose of this investigation was to adapt to an individual physician level and to the paediatric context a set of drug-specific indicators of outpatient antibiotic use developed by the European Surveillance of Antimicrobial Consumption (ESAC) project, and to describe the differences in antibiotic prescriptions between general practitioners (GPs) and paediatricians. We conducted a retrospective cross-sectional study analysing antibiotic prescriptions in 2009 for children below 16 years of age in south-eastern France, using the National Health Insurance (NHI) outpatient reimbursement database. A generalised linear model adjusted on physicians' characteristics and patient population characteristics was used to compare indicators between GPs and paediatricians. We included 4,921 self-employed GPs and 301 paediatricians. Penicillins accounted for 47% and 45% of all antibiotics prescribed by GPs and paediatricians, respectively, followed by cephalosporins (33% and 39%) and macrolides (14% and 9%). In both specialties, there were around 70% more antibiotic prescriptions during the winter quarters compared to the summer quarters. The 13 indicators we calculated showed wide variations in antibiotic prescriptions among GPs, among paediatricians, and between GPs and paediatricians. In an adjusted econometric model, GPs were found to issue 54% more antibiotic prescriptions than paediatricians, whereas paediatricians used a significantly higher proportion of co-amoxiclav (18% vs. 12%) and cephalosporins (39% vs. 33%) and a significantly lower proportion of macrolides (9% vs. 14%) compared to GPs. A set of 13 indicators may be calculated using reimbursement data to describe outpatient antibiotic use at the physician level. We observed very different prescribing profiles between GPs and paediatricians.

Approaching the quality of antibiotic prescriptions in primary care using reimbursement data.

Our objectives for this investigation were: (i) to design quality measures of outpatient antibiotic use that could be calculated at the individual general practitioner (GP) level using reimbursement data only; and (ii) to analyse the variability in antibiotic prescriptions between GPs regarding these measures in south-eastern France. Based on the literature and international therapeutic guidelines, we designed a set of quality measures in an exploratory attempt to assess the quality of antibiotic prescriptions. We performed a cross-sectional study of antibiotic prescriptions in adults in south-eastern France in 2009, using data from the outpatient reimbursement database of the French National Health Insurance (NHI). We carried out a cluster analysis to group GPs according to their antibiotic prescribing behaviour. Six quality measures were calculated at the GP level, with wide variations in practice regarding all these measures. A six-cluster solution was identified, with one cluster grouping 56 % of the sample and made up of GPs having the most homogeneous pattern of prescription for all six quality measures, probably reflecting better antibiotic prescribing. Total pharmaceutical expenses (per patient), penicillin combinations use, quinolone use and seasonal variation of quinolone use were all positively associated with a more heterogeneous and possibly less appropriate use of antibiotics in a multivariate analysis. These quality measures could be useful to assess GPs' antibiotic prescribing behaviour in countries where no information system provides easy access to data linking drug use to a clinical condition.

A 6-year antifungal stewardship programme in a teaching hospital.

PURPOSE: To describe the antifungal stewardship programme in our hospital and to assess its impact on total antifungal prescriptions and their cost, and on the process of care measures regarding the diagnostic and therapeutic management of invasive aspergillosis and candidaemia. METHODS: We conducted a prospective observational study describing the multifaceted antifungal stewardship programme in place at our French teaching tertiary-care hospital since 2005. Several actions were implemented successively, including the systematic evaluation of all costly antifungal prescriptions (echinocandins, lipid formulations of amphotericin B, posaconazole and voriconazole). RESULTS: A total of 636 antifungal prescriptions were discussed by the antifungal management team from 2005 to 2010 inclusive, mainly from the haematology department (72 %). In 344/636 cases (54 %), a piece of advice was fed back to the physician in charge of the patient, with an 88 % compliance rate. Optimal standard of care was achieved for galactomannan antigen testing, performance of chest computed tomography (CT) scan and voriconazole therapeutic drug monitoring for invasive aspergillosis, with no combination therapies used since 2008. Regarding candidaemia, optimal standard of care was achieved for the timing of antifungal therapy, recommended first-line therapy, duration of therapy and the removal of central venous catheters. Total antifungal prescriptions (in defined daily doses, DDD) and their cost were contained between 2003 and 2010. CONCLUSIONS: The implementation of an antifungal stewardship programme was feasible, sustainable and well accepted. We observed an improved quality of care for some process of care measures, and antifungal use and cost were contained in our hospital.

[MR imaging of coronary arteries: noncontrast free-breathing whole heart acquisition with ultrafast 3D balanced gradient-echo technique]. / Imagerie par résonance magnétique des artères coronaires: acquisition "coeur entier", en respiration libre, sans injection d'agent de contraste et utilisant la séquence 3D en écho de gradient balancé ultrarapide.

The 3D balanced gradient-echo technique is described along with th eimaging protocol for MR imaging of th ecoronary arteries. A 3D volume with spatial resolution of 0.6 x 0.6 x 0.75 mm composed of 140 slices covering the whole heart is acquired over 10 minutes. The main advantage of this whole heart technique is the possibility to image the coronary arteries along their entire course in a single acquisition. Selection of the navigator positions, timing of image acquisition and its duration through the R-R interval are the main factors requiring optimization.

[Management of bluespotted stingray injuries in Djibouti from July 2008 to July 2009]. / Prise en charge des piqûres de raies pastenagues à Djibouti de juillet 2008 à juillet 2009.

Although stingray injuries have always been frequent in the Republic of Djibouti, it was not until July 2008 that the Bouffard Hospital developed a standardised management protocol. The purpose of this report is to describe that protocol and evaluate its impact on the outcome of stingray injuries based on a prospective study for the period between July 2008 and July 2009. During the study period, 12 stingray stings were treated. The treatment protocol that is based on a multidisciplinary approach involving the intensivist, anaesthesiologist, and surgeon achieved wound healing within one month. This outcome contrasts with previous publications that have generally described longer healing times with frequent infectious complications.

[Virtual interventional radiology: evaluation of performances as a function of experience]. / Réalité virtuelle en radiologie vasculaire interventionnelle: évaluation des performances de l'opérateur selon son niveau d'expérience.

PURPOSE: To determine the value of an angioplasty simulation to differentiate the users based on their level of experience. To determine the perceived usefulness of an angioplasty simulation program. MATERIALS AND METHODS: Forty-six radiologists performed a renal angioplasty on a VIST simulator (Mentice Corporation, Gothenburg, Sweden); the procedure was completed by 41 radiologists. The radiologists were divided into two groups based on the level of experience. Quantitative variables analyzed included procedure duration time and fluoroscopy time. The radiologists then completed a questionnaire evaluating the simulation program. RESULTS: Radiologists with more than 2 years of clinical experience (n=14) performed the procedures faster (20.4 min vs 27.4 min, p<0.01) using less fluoroscopy time (7.8 min vs 11.2 min, p<0.05) than others. Radiologists performing more than 2 procedures per month (n=14) performed the procedures faster (19.4 min vs 27.9 min, p<0.01) using less fluoroscopy time (7.4 min vs 11.3 min, p<0.05) than other (n=27). The participating radiologists indicated that the simulation was realistic. CONCLUSION: Procedure duration time and duration of fluoroscopy were criteria able to differentiate the users based on their level of experience. The educational value of the simulation program was perceived as helpful by the users.

[Contrast enhanced MR angiography: evolving towards whole-body real time acquisitions]. / Angiographie par résonance magnétique avec injection de produit de contraste: évolution vers le corps entier et le temps réel.

MRA includes all techniques used to depict vessels with MR. Gadolinium contrast injection combined with gradient echo sequences is the technique of choice for vascular imaging. Technical advances now allow faster acquisitions. The purpose of this article is to present two main advances with MRA: whole-body MRA and dynamic 3D MRA. Technical considerations, acquisition techniques, advantages and pitfalls based on our experience with a 1.5T MR unit will be discussed in order to promote their use in routine clinical practice.

HIV infection and care pathway: From guidelines to clinical practice.

OBJECTIVES: To quantify within a cohort of HIV-infected individuals the number of medical visits and procedures to be carried out according to comorbidities and risk factors to implement a personalized care pathway. PATIENTS AND METHODS: Retrospective study of 915 patients consulting from January 1 to December 31, 2016 at an outpatient unit of multidisciplinary consultations, using an electronic patient record. We built an algorithm using parameters required for the application of the national guidelines for the management of HIV-infected individuals. The frequency of comorbidities was measured according to gender, transmission risk group, and nadir CD4 (200/mm3). RESULTS: Patients were mostly men (median age: 52 years), of whom 16% were aged≥60 years. Viral load was<40 copies/mL in 93.5% of treated patients and CD4 cell count≥500/mm3 for 73%. Overall, 74.5% of patients had at least one comorbidity. The number of comorbidities was similar in men and women but was significantly higher in patients with a nadir CD4 <200/mm3 and increased with age (irrespective of gender). The minimum number of consultations to be scheduled per year was 8123: 70% for the management of comorbidities with an average of six consultations/year/patient. Overall, 53% of patients should attend a proctology consultation. The minimum number of paramedical procedures to be performed was 5115. CONCLUSION: The implementation of a personalized multidisciplinary management within a single facility seems to be a suitable care model to address the needs of HIV-infected individuals.

Endovascular versus open revascularization for chronic mesenteric ischemia: a comparative study.

BACKGROUND: The aim of our study was to evaluate and compare short- and long-term outcomes of percutaneous angioplasty and open revascularization for chronic intestinal ischemia. MATERIALS AND METHODS: Twenty-nine consecutive patients undergoing percutaneous angioplasty (n = 14) or open revascularization (n = 15) for chronic intestinal ischemia were prospectively studied from 2000 to 2006. All patients were symptomatic with at least thrombosis or 80% stenosis of superior mesenteric artery. RESULTS: No patient was lost to follow-up. Patients were older in percutaneous angioplasty than in the open revascularization group (p = 0.0009). Open revascularization allowed to revascularize more vessels (1.4 versus 1, p = 0.01). There was no difference between groups regarding major complications, mortality, hospital length of stay, and symptomatic recurrence. Primary re-stenosis was only observed in three patients (21.4%) in the percutaneous angioplasty group. Survival at 2 years estimated by the Kaplan-Meier method was 58% in the percutaneous angioplasty group and 70% in the open revascularization group (p = NS). CONCLUSION: Percutaneous angioplasty should be preferentially offered to older patients and those unable to undergo open revascularization.

[Subsequent pregnancy following uterine artery embolization for interstitial pregnancy]. / Conservation de la fertilité après embolisation sélective d'une grossesse cornuale.

Subsequent pregnancy following an interstitial pregnancy is rare. The risk of uterine rupture may be increased in this situation. Uterine selective embolization has been proposed as an effective treatment. However, no further pregnancy has ever been described after this method of management. We are reporting a case of subsequent pregnancy following interstitial pregnancy managed by embolization. The pregnancy was uneventful. A healthy male infant was delivered by C-section. This case supports the hypothesis that selective embolization for interstitial pregnancy may respect fertility. However, as actual risk of uterine rupture in subsequent pregnancies remains unknown, a C-section is advised.

[Post-partum broad ligament hematoma embolization: a case report]. / Embolisation d'un hématome du ligament large du post-partum: à propos d'un cas.

We relate the embolization of a hematoma of the broad ligament which developed suddenly in the post-partum period. The radiological intervention could be considered as an alternative treatment. The decision for embolization must be a multidisciplinary decision involving all the specialists concerned (interventional radiologist, intensive care specialist, and obstetrician).

Tropheryma whipplei DNA in bronchoalveolar lavage samples: a case control study.

Tropheryma whipplei, the causative bacterium of Whipple's disease, can cause acute pneumonia. We performed a case-control study including patients with T. whipplei in bronchoalveolar lavages (BALs) and controls in order to compare patients' clinical statuses. We tested T. whipplei PCR from January 2013 to December 2014, in all the 1438 BALs in Marseille, France. Controls were hospitalized in the same unit during the same period and were comparable in age and sex. Eighty-eight BALs (6.1%) were positive for T. whipplei and 58 patients had pneumonia. Sixty-four patients were male with a mean age of 50.5 years. T. whipplei was commonly associated with aspiration pneumonia (18/88 patients compared with 6/88 controls, p 0.01) and was detected as a unique pathogen in nine cases. Overall, no difference was observed regarding immunocompromised status. Nevertheless, the six AIDS-infected patients in the T. whipplei group had a significantly lower CD4 level than the five AIDS-infected patients in the control group (49 vs. 320/mm3, p 0.01); in addition, five patients were treated with tumour necrosis factor alpha inhibitors (including three treated by monocolonal antibodies and two with soluble receptor) compared with none of the controls (p 0.03). Pneumocystis jirovecii was frequently associated with the T. whipplei group (7/88 vs. 0/88 in control group), Pseudomonas aeruginosa was only detected in the control group (8/88). This study adds evidence for a causative role of T. whipplei in pneumonia. In the future, an experimental model of pneumonia induced by T. whipplei will prove its role in pneumonia.

The transcriptional regulator Hap1p (Cyp1p) is essential for anaerobic or heme-deficient growth of Saccharomyces cerevisiae: Genetic and molecular characterization of an extragenic suppressor that encodes a WD repeat protein.

We report here that Hap1p (originally named Cyp1p) has an essential function in anaerobic or heme-deficient growth. Analysis of intragenic revertants shows that this function depends on the amino acid preceding the first cysteine residue of the DNA-binding domain of Hap1p. Selection of recessive extragenic suppressors of a hap1-hem1- strain allowed the identification, cloning, and molecular analysis of ASC1 (Cyp1 Absence of growth Supressor). The sequence of ASC1 reveals that its ORF is interrupted by an intron that shelters the U24 snoRNA. Deletion of the intron, inactivation of the ORF, and molecular localization of the mutations show unambiguously that it is the protein and not the snoRNA that is involved in the suppressor phenotype. ASC1, which is constitutively transcribed, encodes an abundant, cytoplasmically localized 35-kD protein that belongs to the WD repeat family, which is found in a large variety of eucaryotic organisms. Polysome profile analysis supports the involvement of this protein in translation. We propose that the absence of functional Asc1p allows the growth of hap1-hem1- cells by reducing the efficiency of translation. Based on sequence comparisons, we discuss the possibility that the protein intervenes in a kinase-dependent signal transduction pathway involved in this last function.

[Important hypercalcaemia due to hyperparathyroidism induced by lithium]. / Hypercalcémie grave secondaire à une hyperparathyroïdie induite par le lithium.

Lithium treatment, which is still extensively used in bipolar affective disorders, may give rise to hypercalcaemia induced by hyperparathyroidism. We present a patient of 50-year-old treated with lithium for 19 years for bipolar illness and who developed an important hypercalcaemia. After symptomatic treatment of the hypercalcaemia and extrarenal dialysis the clinical evolution was favorable but measurements of serum calcium and parathormon showed that he had developed hyperparathyroidism. Neck exploration was performed and parathyroid adenomas, which had been detected by scintigraphy was removed. The lithium treatment expose to many side effects. Among other biologically and clinically important effects of lithium the possible induction of hyperparathyroidism was first suggested in 1973. Since, 1973, since about forty case reports have been described. Few cross-sectional studies show a relationship of lithium to hyperparathyroidism. Unusual metabolic features are associated with hyperparathyroidism and long-term lithium treatment: low urinary calcium excretion, normal urinary cyclic AMP excretion. The mechanism probably results from lithium linking with the calcium receptor on the parathyroid and then stimulating PTH secretion. The cessation of lithium therapy does not lead to normocalocaemia and a parathyroidectomy is usually indicated.

[Renovaascular hypertension and Von Recklinghausen neurofibromatosis]. / Hypertension rénovasculaire et neurofibromatose de Von Recklinghausen.

This clinical case illustrates the diagnosis of a secondary cause of hypertension in a patient with Von Recklinghausen's disease. The hypertension resulted from a complex malformation of the right renal artery and dysplasic stenosis of the left inferior polar artery treated successfully by simple angioplasty. This case illustrates the high proportion of vascular (renal artery dysplasia, coarctation of the aorta) and endocrine (pheochromocytoma) causes of hypertension in patients with neurofibromatosis.

[Are demographic characteristics of hypertensive patients different with renal artery stenosis?]. / Les caractéristiques démographiques des hypertendus sont-elles différentes en présence d'une sténose artérielle athéromateuse rénale?

UNLABELLED: Atheromatous renal disease is more and more involved in end stage renal failure in polyatheromatous patients. The goal of this work was to study the demographic differences between hypertensive patients with renal artery stenosis (RAS) or without RAS. METHOD: Between November 1995 and July 1997, 49 hypertensive patients were included consecutively for a suspicion of RAS. Age, sex, hypertension history, tabagism, cardiovascular heredity, body mass index, diabetes history, hypercholesterolemia, kalmia, serum creatinine, creatinine clearance, systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP) were studied. A renal echo-doppler and a renal TDM were performed in all patients. A renal arteriography was performed in 23 patients with a RAS suspicion after the two morphologic exams. The demographic characteristics of both clinical groups control (group 1) and patients with unilateral RAS (group 2), were compared. STATISTICS: Descriptive analysis, Wilcoxon test, Khi 2 test, spearman correlation (p < 0.05). RESULTS: Group 2 patients were significantly older than group 1 patients (p = 0.008) with a mean age difference of 8 years. Creatinine clearance was lower in patients suffering from RAS with a mean difference of 23 mL/min between groups 1 and 2 (p = 0.0007) but we also had to take into account the negative correlation existing between creatinine clearance and age (r = 0.63; p = 0.0001) when interpreting these results. The DBP was lower (p = 0.03) and the PP higher (p = 0.01) in group 2. The SBP was higher in group 2 but this result was not significant. Mean differences in SBP and PP between group 1 and group 2 were 6 mmHg and 15 mm Hg respectively. Smoking was more common in group 2 (p = 0.04). The history of hypertension, cardiovascular heredity, sex ratio (M/F), body mass index and prevalence of diabetic were comparable between the two clinical groups. CONCLUSION: Although there were demographic differences between the two clinical groups, no clinical or biological variable could be used alone to identify which patients suffered from renal stenosis, because the distribution of these variables did not differ significantly between the two groups and the effective was small. Then, we thought that Krijnen's predictive rule is interesting in the screening of hypertensive patients with RAS suspicion.
