RESUMEN
Pubic bone osteomyelitis is a rare infection, mostly related to urinary fistula. The published data about the medical or surgical management of this type of infection is relatively poor. In this case study of three patients, we describe our surgical technique for the management of urosymphyseal fistula complicated with pubic bone infection using pelvic filling flap by unilateral pedicled myocutaneous vertical rectus abdominus muscle flap. The first patient had the pelvic space filled with omentum flap. Unfortunately, the patient presented, postoperatively, an enteric fistula resulting from intestine incarceration on the resected bone. Considering this failure, the next two cases, have benefited from a Taylor flap to protect the peritoneal cavity by covering the residual pubic bone. Early complications were pyelonephritis and anemia (Clavien-Dindo 2), but no repeat surgery was required afterwards. The hospital stay for both cases were 26- and 12-days contrary to the first case who was hospitalized for 180-days. In conclusion, despite our limited experience in managing complicated urosymphyseal fistula, Taylor's flap, mainly used for gynecological or rectal surgery, might be a good reproducible solution for the surgical management of this kind of fistula with pubic debridement. It allows to protect the peritoneal cavity with fewer postoperative complications.
RESUMEN
INTRODUCTION: Polypharmacy can lead to drug-drug interactions (DDIs), especially with ART. The burden of co-medications, including over-the-counter (OTC) drugs and self-medications, could be underestimated. We aimed to investigate the proportion of people living with HIV (PLHIV) with declared and undeclared co-medications, as well as their potential burden. METHODS: We conducted a national, multicentre, 1 week cross-sectional study between 10 December and 16 December 2019 in 23 French hospitals amongst consecutive adult PLHIV presenting for a routine outpatient visit. A standardized questionnaire filled in by the physicians assessed all medications and other active chemical substances taken by the PLHIV. RESULTS: Overall we enrolled 496 participants from 23 centres. Median age was 50.6 years; ART regimens included an integrase inhibitor in 61% (nâ=â302), an NNRTI in 34% (nâ=â169) and a PI in 14% (nâ=â70) of the cases. Co-medications involved 392 (79%) PLHIV, among which 85 (17%) received polypharmacy (≥5 medications). Previously unknown co-medications or other active substances were found for 32% (nâ=â159) of the participants. Corticosteroids (9%, nâ=â46) and proton pump inhibitors (10%, nâ=â50) were frequently administered. These co-medications did not differ according to age range. Illegal drug use was declared by 11% (nâ=â54) and OTC drugs by 23% (nâ=â113) of PLHIV. Potential DDIs were discovered for 11% (nâ=â53), leading to treatment modifications in 47% (25/53) of cases. CONCLUSIONS: Potential DDIs that lead to therapeutic modifications remain significant whatever the age of PLHIV. More devoted time to identify co-medications and OTC treatment is needed in all PLHIV.

OBJECTIVES: The management of patients with bone and joint infections (BJIs) is complex. To improve this care, we carried out pharmaceutical actions in the orthopedic unit, including pharmacist-led-intervention (PLI) for patients requiring prolonged antibiotics. Few data exist regarding patient compliance, adherence and knowledge in cases of BJI. Data on hospital readmission are likewise limited, even though it is considered as a major determinant of clinical impact. The aim of this study was to assess the effectiveness of PLI regarding six-month readmissions. PATIENTS AND METHODS: Patients were assigned to two groups, both receiving standardized care. Two periods were compared: control group (CG) without PLI and interventional group (IG) with PLI throughout. The analysis was based on patient records and included: proportion of rehospitalizations at 6 months for infectious causes, reasons for antibiotic dose modification or antibiotic switch after 6 weeks, and descriptive analysis of data on pharmaceutical interventions in care pathways. RESULTS: Analysis was performed on 164 patients: 105 CG (64 %) patients and 59 IG (36 %) patients. There were no significant differences between IG and CG in patients' socio-demographic characteristics, infectious factors and antibiotic regimens. Amongst the CG patients, 23 were readmitted (22 %) versus 3 patients in the IG (5 %), (p = 0.002). There were significantly fewer treatment changes after 6 weeks (28.6 % versus 15.3 %, p = 0.05) for IG patients. CONCLUSION: In this retrospective survey, our results suggest a positive impact of PLI on 6-month readmission for all causes in BJI patients. These results need to be confirmed in a multicentric study.

BACKGROUND: Enterococcus faecalis infective endocarditis (EFIE) is characterized by a higher frequency of relapses than other infective endocarditis. The role of the treatment on its occurrence remains poorly understood. The aim of this study was to investigate whether the antibiotic regimen could impact the risk of relapse in EFIE. MATERIALS: This was a multicenter retrospective study of patients diagnosed with definite EFIE between 2015 and 2019 in 14 French hospitals. The primary endpoint was the occurrence of relapses within the year following endocarditis diagnosis. As death was a competing risk for relapse, Fine and Gray models were used for studying risk factors and impact of treatment. RESULTS: Of the 279 patients included, 83 (29.7%) received the amoxicillin-gentamicin (A-G) combination, 114 (40.9%) amoxicillin-ceftriaxone (A-C), 63 (22.6%) A-G and A-C (A-G/A-C) sequentially, 9 (3.2%) amoxicillin (A), and 10 received other treatments. One-year-relapse rate was 9.3% (26 patients). Relapse occurred after a median delay of 107 days from EFIE diagnosis; 6 occurred after 6 months, and 6 were diagnosed by blood cultures in asymptomatic patients. In multivariate analysis, surgery during treatment was a protective factor against one-year relapse and death.The cumulative incidence of relapse 1 year after endocarditis was 46.2% for patients treated with amoxicillin, 13.4% with A-G, 14.7% with A-C, and 4.3% with A-G/A-C (P≥.05 in multivariate analysis). CONCLUSIONS: Relapses after treatment of EFIE are frequent, frequently asymptomatic, and may occur more than 6 months after the initial episode.

Background: Screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) at pharyngeal, urogenital, and anorectal sites is recommended for men who have sex with men (MSM). Pooling samples is a promising technique, but no data are available when pooled screening also includes Mycoplasma genitalium (MG). The main objective of this study was to examine the sensitivity of pooled samples for detecting CT, NG, and MG in MSM using nucleic acid amplification versus single-site testing. Methods: In this multicenter study, MSM with a positive result for CT, NG, or MG were recalled to the clinic for treatment and were asked to participate in this study. Separate samples were sent to a central virological department that proceeded to form the pooled samples. Testing was performed using the multiplex real-time polymerase chain reaction Allplex STI Essential Assay (Seegene, Seoul, Korea), which can simultaneously detect 7 pathogens. Results: A total of 130 MSM with at least 1 positive test for CT, NG, or MG were included. A total of 25.4% had a coinfection. The sensitivities of pooled-sample testing were 94.8% for CT, 97.0% for NG, and 92.3% for MG. Pooling failed to detect 8 infections, but pooled-sample analysis missed detecting only samples with a low bacterial load (cycle threshold >35). Conclusions: Pooling samples from MSM to detect CT, NG, and MG is as sensitive as individual-site testing for these 3 pathogens using the Allplex assay. Missed infections with a very low bacterial load could have a low impact on further transmission. Clinical Trials Registration. NCT03568695.
RESUMEN
Doravirine (DOR) efficacy and safety have been evaluated in adult naive or treated patients starting a DOR-based regimen between September 15, 2019, and December 31, 2020. Medical history and examination, laboratory results, and tolerance were assessed during the 48 weeks of follow-up. Among the 77 patients included, virological control (VC) was noticed for 66 patients at baseline. Median age was 51 years, and 62% were men. The most common reason for initiating a DOR-based therapy was toxicity (44; 67%) and, especially, weight gain. A virological suppression (VS) was maintained in 55 (83%) patients of the VC group and noticed in 9 (82%) of the non-VC patients at week 48, by intention-to-treat analysis. On treatment analysis, 98% and 100% patients achieved VS in the VC and non-VC groups, respectively. The renal and metabolic tolerance were good. DOR-based regimens appear to be a safe and relevant strategy to circumvent drug interactions and drugs with a poor metabolic tolerance profile.

BACKGROUND: The management of prosthetic joint infection usually consists of a combination of surgery and antimicrobial therapy. The appropriate duration of antimicrobial therapy for this indication remains unclear. METHODS: We performed an open-label, randomized, controlled, noninferiority trial to compare 6 weeks with 12 weeks of antibiotic therapy in patients with microbiologically confirmed prosthetic joint infection that had been managed with an appropriate surgical procedure. The primary outcome was persistent infection (defined as the persistence or recurrence of infection with the initial causative bacteria, with an antibiotic susceptibility pattern that was phenotypically indistinguishable from that at enrollment) within 2 years after the completion of antibiotic therapy. Noninferiority of 6 weeks of therapy to 12 weeks of therapy would be shown if the upper boundary of the 95% confidence interval for the absolute between-group difference (the value in the 6-week group minus the value in the 12-week group) in the percentage of patients with persistent infection within 2 years was not greater than 10 percentage points. RESULTS: A total of 410 patients from 28 French centers were randomly assigned to receive antibiotic therapy for 6 weeks (205 patients) or for 12 weeks (205 patients). Six patients who withdrew consent were not included in the analysis. In the main analysis, 20 patients who died during follow-up were excluded, and missing outcomes for 6 patients who were lost to follow-up were considered to be persistent infection. Persistent infection occurred in 35 of 193 patients (18.1%) in the 6-week group and in 18 of 191 patients (9.4%) in the 12-week group (risk difference, 8.7 percentage points; 95% confidence interval, 1.8 to 15.6); thus, noninferiority was not shown. Noninferiority was also not shown in the per-protocol and sensitivity analyses. We found no evidence of between-group differences in the percentage of patients with treatment failure due to a new infection, probable treatment failure, or serious adverse events. CONCLUSIONS: Among patients with microbiologically confirmed prosthetic joint infections that were managed with standard surgical procedures, antibiotic therapy for 6 weeks was not shown to be noninferior to antibiotic therapy for 12 weeks and resulted in a higher percentage of patients with unfavorable outcomes.

OBJECTIVES: Low HIV reservoirs may be associated with viral suppression under a lower number of antiretroviral drugs. We investigated tenofovir disoproxil fumarate/emtricitabine as a maintenance strategy in people living with HIV (PLHIV) with low HIV-DNA. METHODS: TRULIGHT (NCT02302547) was a multicentre, open-label, randomized trial comparing a simplification to tenofovir disoproxil fumarate/emtricitabine versus a triple regimen continuation (tenofovir disoproxil fumarate/emtricitabine with a third agent, control arm) in virologically suppressed adults with HIV-DNA <2.7 log10 copies/106 PBMCs and no prior virological failure (VF). The primary endpoint (non-inferiority margin 12%) was the percentage of participants with a plasma viral load (pVL) <50 copies/mL in ITT (Snapshot approach) and PP analyses at Week 48 (W48). RESULTS: Of the 326 participants screened, 223 (68%) were randomized to the tenofovir disoproxil fumarate/emtricitabine arm (n = 113) or control arm (n = 110). At W48, the tenofovir disoproxil fumarate/emtricitabine and control arms maintained a pVL < 50 copies/mL in 100/113 (88.5%) and 100/110 (90.9%) participants, respectively (ITT difference 2.4%, 95% CI -5.9 to 10.7; PP difference 3.4%, 95% CI -4.2 to 11.0). Six VFs occurred in the tenofovir disoproxil fumarate/emtricitabine arm (two with emerging mutations M184V and K65R) versus two in the control arm (ITT difference 3.5%, 95% CI -1.9 to 9.4). All VFs were resuppressed after treatment modification. CONCLUSIONS: Although non-inferiority was shown, simplification to tenofovir disoproxil fumarate/emtricitabine should not be used for most PLHIV because of a low risk of VF with resistance.

Optimal management of patients experiencing persistent low-level viremia (LLV) remains challenging and poorly understood. This study aimed to assess the association between poor antiretroviral treatment (ARV) adherence and persistent LLV. ADHELOW is a sub-study of the ECHEC cohort comprising HIV-infected adults with virological failure (viral load>50 copies/mL). Patients were recruited in 2013-2015 from 4 French university hospitals. Those with LLV (i.e., ≥2 viral load measurements between 50 and 500 copies/mL) were selected and matched on age and sex to 3 controls with virological suppression. The adherence rate was estimated using pharmacy-delivered prescription refills over one year. Overall, 60 patients were included (15 LLV and 45 controls). Mean age was 50.20 years, M/F sex ratio was 14 and mean EPICES (social deprivation) score was 42.90. In univariable analyses, LLV patients had significantly lower adherence (<80%: 53.30% vs. 6.67%, p < 0.01) and were more likely to have an EPICES score >40.2 (60.00% vs. 24.44%, p < 0.01). In multivariable analysis, these two variables remained significantly associated with LLV (OR 31.49, CI 95% [4.54-218.70]) and OR 11.00 (CI 95% [1.87-218.70], respectively). Poor long-term treatment adherence, estimated by prescription refills, was strongly associated with LLV. This reinforces the message that adherence counseling should be the primary intervention to overcome LLV.

BACKGROUND: During this pandemic situation, some studies have led to hasty conclusions about Corona Virus Disease-19 (COVID-19) treatment, due to a lack of methodology. This pedagogic study aimed to highlight potential biases in research on COVID-19 treatment. METHODS: We evaluate the effect of coffee's active part, 1,3,7-trimethylxanthine (TMX) on patients with COVID-19. A cohort of 93 patients, with a diagnosis of COVID-19 is analyzed. RESULTS: TMX group and control group included, respectively, 26 and 67 patients. In the TMX group, patients had a median length of stay in hospital of 5.5 days shorter than in the control group (9.5 vs. 15 days, p < 0.05). Patients in the control group were more severe than patients in the TMX group with a significantly higher National Early Warning Score 2 (NEWS-2 score) (8 vs. 6, p = 0.002). CONCLUSIONS: Multiple biases prevents us from concluding to an effect of coffee on COVID-19. Despite an important social pressure during this crisis, methodology and conscientiousness are the best way to avoid hasty conclusions that can be deleterious for patients. Identifier: NCT04395742.
RESUMEN
Initially isolated from the alimentary canal of a Japanese corbicula clam, Oscillibacter valericigenes is a Gram-negative rod, of which culture remains very difficult. Herein we present the first case of bacteremia due to Oscillibacter valericigenes, in humans. A 55-year-old man was hospitalized for clinical management of multiple neglected leg wounds (colonized with maggots) that had occurred during a motorcycle accident. Following radiological confirmation of the bone infection, a transfemoral amputation was performed to limit the risk of extended infection. During hospitalization, before the amputation, the patient experienced fever, biological inflammation justifying the sampling of multiple blood cultures. Anaerobic blood culture was positive after 34 hours, without identification by routine procedure (MALDI-TOF), justifying identification by 16S DNA sequencing. In the absence of possible subculture, antibiotic sensitivity testing could not be performed. A pre-emptive treatment by piperacillin-tazobactam was introduced for 14 days. The evolution was good, except for a local disunion. Complete phylogenic analysis of the clinical strain showed that it significantly differed from the reference strain, which is distantly related to the Clostridia cluster IV. Due to the culture conditions and specialized identification method by sequencing, prevalence of O. valericigenes may be underestimated. Optimization of blood culture procedures and utilization of 16S rRNA gene sequencing are tools needed for identification of rare pathogens that could help to optimize clinical management of infected patients.

While treatment of serious infectious diseases may require high-dose amoxicillin, continuous infusion may be limited by lack of knowledge regarding the chemical stability of the drug. Therefore, we have performed a comprehensive study so as to determine the chemical stability of high-dose amoxicillin solutions conducive to safe and effective continuous intravenous administration using portable elastomeric pumps. First, amoxicillin solubility in water was assessed within the range of 25 to 300 mg/mL. Then, amoxicillin solutions were prepared at different concentrations (25, 50, 125, 250 mg/mL) and stored in different conditions (5±2°C, 25±1°C, 30±1°C and 37±1°C) to investigate the influence of concentration and temperature on the chemical stability of amoxicillin. Finally, its stability was assessed under optimized conditions using a fully validated HPLC-UV stability-indicating method. Degradation products of amoxicillin were investigated by accurate mass determination using high-resolution mass spectrometry. Amoxicillin displayed limited water solubility requiring reconstitution at concentrations below or equal to 150 mg/mL. Amoxicillin degradation were time, temperature as well as concentration-dependent, resulting in short-term stability, in particular at high concentrations. Four degradation products of amoxicillin have been identified. Among them, amoxicilloic acid and diketopiperazine amoxicillin are at risk of allergic reaction and may accumulate in the patient. Optimized conditions allowing for continuous infusion of high-dose amoxicillin has been determined: amoxicillin should be reconstituted at 25 mg/mL and stored up to 12 hours at room temperature (22 ± 4°C) or up to 24 hours between 4 and 8°C.

BACKGROUND: The optimal treatment of streptococcal prosthetic joint infections (PJIs) is unclear. METHODS: A cohort of streptococcal PJIs was reviewed retrospectively in seven reference centers for the management of complex bone and joint infections, covering the period January 1, 2010 to December 31, 2012. RESULTS: Seventy patients with monomicrobial infections were included: 47 had infections of total hip arthroplasty and 23 had infections of total knee arthroplasty. The median age was 77 years (interquartile range (IQR) 69-83 years), the median Charlson comorbidity score was 4 (IQR 3-6), and 15.6% (n=11) had diabetes. The most commonly identified streptococcal species were Streptococcus agalactiae and Streptococcus dysgalactiae (38.6% (n=27) and 17.1% (n=12), respectively). Debridement, antibiotics and implant retention (DAIR) was performed after a median time of 7 days (IQR 3-8 days), with polyethylene exchange (PE) in 21% of cases. After a minimum follow-up of 2 years, 27% of patients had relapsed, corresponding to 51.4% of DAIR treatment cases and 0% of one-stage (n=15) or two-stage (n=17) exchange strategy cases. Rifampicin or levofloxacin in combination therapy was not associated with a better outcome (adjusted p= 0.99). S. agalactiae species and DAIR treatment were associated with a higher risk of failure. On multivariate analysis, only DAIR treatment and S. agalactiae were independent factors of relapse. Compared to DAIR without PE, DAIR with PE was only associated with a trend towards a benefit (odds ratio 0.33, 95% confidence interval 0.06-1.96; adjusted p= 0.44). CONCLUSIONS: Streptococcal PJIs managed with DAIR have a poor prognosis and S. agalactiae seems to be an independent factor of treatment failure.

BACKGROUND: We investigated whether dolutegravir (DTG) monotherapy could be used to maintain virological suppression in people living with human immunodeficiency virus (HIV) on a successful dolutegravir-based triple therapy. METHODS: MONCAY (MONotherapy of TiviCAY) was a 48-week, multicentric, randomized, open-label, 12% noninferiority margin trial. Patients with CD4 nadir >100/µL, plasma HIV-1 RNA <50 copies/mL for ≥12 months, and stable regimen with DTG/abacavir (ABC)/lamivudine (3TC) were 1:1 randomized to continue their regimen or to DTG monotherapy. The primary endpoint was the proportion of patients with HIV RNA <50 copies/mL at week 24 in intention-to-treat snapshot analysis. Virologic failure (VF) was defined as 2 consecutive HIV RNA >50 copies/mL within 2 weeks apart. RESULTS: Seventy-eight patients were assigned to DTG monotherapy and 80 to continue DTG/ABC/3TC. By week 24, 2 patients in the DTG group experienced VF without resistance to the integrase strand transfer inhibitor (INSTI) class; 1 patient discontinued DTG/ABC/3TC due to an adverse event. The success rate at week 24 was 73/78 (93.6%) in the DTG arm and 77/80 (96.3%) in the DTG/ABC/3TC arm (difference, 2.7%; 95% confidence interval [CI], -5.0 to 10.8). During subsequent follow-up, 5 additional VFs occurred in the DTG arm (2 of which harbored emerging resistance mutation to INSTI). The cumulative incidence of VF at week 48 was 9.7% (95% CI, 2.8 to 16.6) in the DTG arm compared with 0% in the DTG/ABC/3TC arm (P = .005 by the log-rank test). The Data Safety Monitoring Board recommended to reintensify the DTG arm with standardized triple therapy. CONCLUSIONS: Because the risk of VF with resistance increases over time, we recommend avoiding DTG monotherapy as a maintenance strategy among people living with chronic HIV infection. CLINICAL TRIALS REGISTRATION: NCT02596334 and EudraCT 2015-002853-36.

Invasive fungal infection is a serious complication following allogeneic hematopoietic stem cell transplantation. Pulmonary infection due to Hormographiella aspergillata is an uncommon condition associated with a high mortality rate. The susceptibility of H. aspergillata to available antifungal agents is not well established. We report for the first time a case of H. aspergillata lung infection that responded poorly to conventional treatment with liposomal amphotericin B (LAmB; 3 mg kg-1 of body weight per day) with renal damage at higher posology (5 mg kg-1 of body weight per day), but improved rapidly after addition of nebulized LAmB to intravenous LAmB (3 mg kg-1 of body weight per day). Successful treatment of our patient using nebulized LAmB would be worth evaluating in cases refractory to standard treatment or when the reference treatment may not be extended due to interaction or side effects.

Data regarding the efficacy of Rapid HIV tests (RHTs) in detecting non-B subtype HIV-1 are limited. We evaluated the sensitivity of the INSTI® test for the detection of HIV-1 antibodies for the diagnosis of HIV-1 non-B subtypes and recombinant variants. We identified adults with HIV-1 infection due to non-B subtypes and recombinant variants. The participants were re-tested with INSTI® test. We included 258 patients. Overall, the INSTI® test sensitivity was 98.4% (95%CI: 96.9-99.9%). For the major CRF_02AG subtype, the sensitivity was 99.0% (95%CI: 97.1-100%). The HIV INSTI® test is reliable for the detection of various non-B HIV-1 antibodies.
