Clinical characteristics of women with HIV in the RESPOND cohort: A descriptive analysis and comparison to men.

BACKGROUND: Women with HIV are globally underrepresented in clinical research. Existing studies often focus on reproductive outcomes, seldom focus on older women, and are often underpowered to assess sex/gender differences. We describe CD4, HIV viral load (VL), clinical characteristics, comorbidity burden, and use of antiretroviral therapy (ART) among women with HIV in the RESPOND study and compare them with those of the men in RESPOND. METHODS: RESPOND is a prospective, multi-cohort collaboration including over 34 000 people with HIV from across Europe and Australia. Demographic and clinical characteristics, including CD4/VL, comorbidity burden, and ART are presented at baseline, defined as the latter of 1 January 2012 or enrolment into the local cohort, stratified by age and sex/gender. We further stratify men by reported mode of HIV acquisition, men who have sex with men (MSM) and non-MSM. RESULTS: Women account for 26.0% (n = 9019) of the cohort, with a median age of 42.2 years (interquartile range [IQR] 34.7-49.1). The majority (59.3%) of women were white, followed by 30.3% Black. Most women (75.8%) had acquired HIV heterosexually and 15.9% via injecting drug use. Nearly half (44.8%) were receiving a boosted protease inhibitor, 31.4% a non-nucleoside reverse transcriptase inhibitor, and 7.8% an integrase strand transfer inhibitor. The baseline year was 2012 for 73.2% of women and >2019 for 4.2%. Median CD4 was 523 (IQR 350-722) cells/µl, and 73.6% of women had a VL <200 copies/mL. Among the ART-naïve population, women were more likely than MSM but less likely than non-MSM (p < 0.001) to have CD4 <200 cells/µL and less likely than both MSM and non-MSM (p < 0.001) to have VL ≥100 000 copies/mL. Women were also more likely to be free of comorbidity than were both MSM and non-MSM (p < 0.0001). CONCLUSION: RESPOND women are diverse in age, ethnicity/race, CD4/VL, and comorbidity burden, with important differences relative to men. This work highlights the importance of stratification by sex/gender for future research that may help improve screening and management guidelines specifically for women with HIV.

[Fatal outcome in a patient coinfected by malaria and HIV]. / Issue fatale chez un patient coinfecté par le VIH et la malaria.

Imported malaria is a pathology mainly due to Plasmodium falciparum. For patients with co- morbidities, such as HIV or believing themselves immune, the risk of malaria is more severe. We present the case of a HIV patient carrier with a cerebral malaria of letal evolution despite a rapid decline in its parasitaemia using Artesunate. This case describes the relationship HIV-malaria, stresses the place of Artesunate, and insist on the importance of preventive measures for malaria acquisition for any person with HIV traveling to endemic areas.

La malaria importée est une pathologie due principalement au Plasmodium falciparum. Pour les patients porteurs de comorbidités comme le VIH ou se croyant immunisés, le risque de malaria est plus sévère. Nous présentons le cas d'un patient porteur du VIH avec une malaria cérébrale d'évolution mortelle, malgré une diminution rapide de sa parasitémie grâce à l'utilisation d'Artesunate. Ce cas décrit les relations VIH- malaria, souligne la place de l'Artesunate, et insiste sur l'importance des mesures de prévention d'acquisition de la malaria auprès de toute personne VIH voyageant vers les zones endémiques.

[HPV prophylactic vaccines]. / La vaccination préventive contre HPV.

Since 2007, two prophylactic vaccines against Human Papillomavirus (HPV) infection and HPV. induced lesions (both precancerous dysplasia and cancer) have been registered in Belgium. In multicentre randomized trials including more than 64,000 patients, these vaccines were shown to be highly efficient against the occurrence of condyloma and of dysplastic lesion in the cervix, vagina and vulva in females and in the anus in males. These vaccines display an excellent tolerance and safety profile, the most common adverse event being minor and transient side effects at the injection site. The protection given by these vaccines is more important in subjects that have not been in contact with HPV previously ; moreover the title of neutralizing antibodies against HPV are significantly higher in children vaccinated before 15 years-old age compared to young person vaccinated after this age. For these two reasons, it is recommended to vaccinate before the first sexual relationships. Recently, several studies have demonstrated that vaccination by two doses given at 0 and 6 months in children before 15 years-old was equivalent to the three doses scheme that should be given at 0, 1 or 2 and 6 months in subjects aged 15 years or more. In the countries that have achieved a high vaccine coverage among their young female population, the prevalence of HPV infection and the incidence of high grade cervical dysplasia have significantly decreased while condyloma has almost disappeared four years after the implementation of HPV vaccination. In HIV-positive subjects who are particularly susceptible to infection and lesions induced by HPV, vaccination brings levels of antibody comparable to what is found in the general population with similar safety.

Saccharomyces cerevisiae fungemia: Risk factors, outcome and links with S. boulardii-containing probiotic administration.

Saccharomyces cerevisiae fungemia: risk factors, outcome and links with S. boulardii-containing probiotic administration. OBJECTIVE: The aim of our study was to review cases of S. cerevisiae fungemia along with the corresponding risk factors (including S. boulardii probiotic intake), treatment and outcomes. PATIENTS AND METHODS: Retrospective study (2005-2017) of S. cerevisiae fungemia. All the data were extracted from medical files. RESULTS: We identified 10 patients with S. cerevisiae fungemia. Mean age was 59.4 years (range 21-88). Four fifths (80%) were on total parenteral or enteral nutrition, 70% had a central venous line, and 30% were admitted in an Intensive Care Unit (ICU). S. boulardii-containing probiotic prescription was identified in 6 subjects. Three patients with no risk factors such as ICU or central venous catheter were 80 years old or more. Mortality rate was 50%. CONCLUSION: S. cerevisiae fungemia is a rare but life-threatening infection, associated with intake of probiotics containing S. boulardii. Besides classical risk factors, older age should be a contraindication for these probiotics.

Contribution of the FilmArray Respiratory Panel in the management of adult and pediatric patients attending the emergency room during 2015-2016 influenza epidemics: An interventional study.

AIM: To evaluate the contribution of a multiplex PCR for respiratory viruses on antibiotic and antiviral prescription, ancillary test prescription, admission and length of stay of patients. METHODS: Two hundred ninety-one adult and pediatric patients visiting the emergency department during the 2015-2016 influenza epidemic were prospectively included and immediately tested 24/7 using the FilmArray Respiratory Panel. The results were communicated to the practitioner in charge as soon as they became available. Clinical and biological data were gathered and analyzed. FINDINGS: Results from the FilmArray Respiratory Panel do not appear to impact admission or antibiotic prescription, with the exception of a lower admission rate for children who tested positive for influenza B. Parameters that account for the clinical decisions evaluated are CRP level, white blood cell count, suspected or proven bacterial infection and, for adult patients only, signs of respiratory distress. Length of stay is also not significantly different between patients with a positive and a negative result. A rapid influenza test result permits a more appropriate prescription of oseltamivir.

Prospective evaluation of diagnostic tools for respiratory viruses in children and adults.

AIM: To compare the performances of molecular and non-molecular tests to diagnose respiratory viral infections and to evaluate the pros and contras of each technique. METHODS: Two hundred ninety-nine respiratory samples were prospectively explored using multiplex molecular techniques (FilmArray Respiratory Panel, Clart Pneumovir), immunological techniques (direct fluorescent assay, lateral flow chromatography) and cell cultures. FINDINGS: Molecular techniques permitted the recovery of up to 50% more respiratory pathogens in comparison to non-molecular methods. FilmArray detected at least 30% more pathogens than Clart Pneumovir which could be explained by the differences in their technical designs. The turnaround time under 2 hours for the FilmArray permitted delivery of results when patients were still in the emergency room.

Hemophagocytic lymphohistiocytosis associated to Haemophilus parainfluenzae endocarditis- a case report.

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a rare but severe and potentially fatal syndrome that is characterized by increased proliferation and activation of benign macrophages with hemophagocytosis throughout the reticuloendothelial system. This syndrome is classified as primary (genetic) or secondary when acquired in the context of infections (usually viral), malignancies, rheumatologic and metabolic diseases. CASE SUMMARY: We report a case of HLH complicating a Haemophilus parainfluenzae mitral valve endocarditis and resolving under antibiotic and surgical treatment alone. We also review other case reports of infective endocarditis associated with HLH. CONCLUSION: The syndrome is probably underdiagnosed. To our knowledge, this is the first report of a HLH syndrome associated with H. parainfluenzae endocarditis.

MALDI-TOF MS contribution to the diagnosis of Campylobacter rectus multiple skull base and brain abscesses.

Campylobacter rectus is rarely associated with invasive infection. Both the isolation and the identification requirements of C. rectus are fastidious, probably contributing to an underestimation of its burden. We report the case of a 66-year-old man who developed several skull base and intracerebral abscesses after dental intervention. Campylobacter rectus was isolated from the brain biopsy. Within 45 minutes of reading the bacterial plate, the strain was accurately identified by MALDI-TOF MS. This rapid identification avoided the extra costs and delays present with 16S rRNA gene sequencing and allowed for a rapid confirmation of the adequacy of the empirical antibiotic treatment.

PET findings in a brain abscess associated with a silent atrial septal defect.

Brain abscesses are classical complications of congenital heart disease (CHD) in children and adolescents. This association is rarely observed in adults. We report a 46-year-old man presenting a fronto-parietal abscess associated with an asymptomatic atrial septal defect. Positron emission tomography (PET) study revealed high uptake of L-[methyl-11C]methionine ([11C]methionine) and 2-[18F]fluoro-2-deoxy-D-glucose (FDG) around the brain abscess. We suggest (1) to exclude a silent cardiac malformation in the presence of a cerebral abscess of unknown source occurring in adults; (2) to consider the diagnosis of brain abscess in cases of high uptake of [11C]methionine and FDG in relation to a brain lesion.

Impact of rapid microbial identification directly from positive blood cultures using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry on patient management.

For septic patients, delaying the initiation of antimicrobial therapy or choosing an inappropriate antibiotic can considerably worsen their prognosis. This study evaluated the impact of rapid microbial identification (RMI) from positive blood cultures on the management of patients with suspected sepsis. During a 6-month period, RMI by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was performed for all new episodes of bacteraemia. For each patient, the infectious disease specialist was contacted and questioned about his therapeutic decisions made based on the Gram staining and the RMI. This information was collected to evaluate the number of RMIs that led to a therapeutic change or to a modification of the patient's general management (e.g. fast removal of infected catheters). During the study period, 277 new episodes of bacteraemia were recorded. In 71.12% of the cases, MALDI-TOF MS resulted in a successful RMI (197/277). For adult and paediatric patients, 13.38% (21/157) and 2.50% (1/40) of the RMIs, respectively, resulted in modification of the treatment regimen, according to the survey. In many other cases, the MALDI-TOF MS was a helpful tool for infectious disease specialists because it confirmed suspected cases of contamination, especially in the paediatric population (15/40 RMIs, 37.50%), or suggested complementary diagnostic testing. This study emphasizes the benefits of RMI from positive blood cultures. Although the use of this technique represents an extra cost for the laboratory, RMI using MALDI-TOF MS has been implemented in our daily practice.

Indinavir/ritonavir-based therapy in HIV-1-infected antiretroviral therapy-naive patients: comparison of 800/100 mg and 400/100 mg twice daily.

Objectives To compare the efficacy and tolerability of indinavir (IDV)/ritonavir (RTV) at 800/100 and 400/100 mg twice daily (bid) in antiretroviral therapy (ART)-naive patients. Methods An open comparison of two groups of ART-naive patients treated with IDV/RTV 800/100 or 400/100 mg bid plus two nucleoside analogues was carried out. Viral load, CD4 cell count and tolerability were measured at baseline and at weeks 4, 12, 24 and 48. IDV plasma concentrations were measured retrospectively. Results A total of 107 patients were included in the study. Of these, 57 were treated with 800/100 and 50 with 400/100 mg IDV/RTV bid. At week 48, a viral load of <50 HIV-1 RNA copies/mL was achieved by 77 and 64% of the patients, respectively, and the median CD4 cell count increases were +171 and +164 cells/muL (intent-to-treat; P not significant), respectively. Side effects leading to protease inhibitor discontinuation occurred in 61% of subjects in the 800/100 mg group vs. 20% in the 400/100 mg group (P<0.0001). Switching from 800/100 to 400/100 mg dosage improved adverse events in 16 of 20 patients. IDV concentrations were above 0.15 mg/L in 89% of the 28 patients tested in the 400/100 mg group. Conclusions Indinavir/ritonavir 400/100 mg bid provided the same efficacy as 800/100 mg bid at 48 weeks in an ART-naive population, but safety and tolerance were significantly better for 400/100 mg, while convenience was also improved and cost was reduced.
