Objectives: The aim was to describe the effectiveness of suppressive antibiotic treatment (SAT) in routine clinical practice when used in situations in which removal of a prosthetic implant is considered essential for the eradication of an infection, and it cannot be performed. Methods: This was a descriptive retrospective and multicentre cohort study of prosthetic joint infection (PJI) cases managed with SAT. SAT was considered to have failed if a fistula appeared or persisted, if debridement was necessary, if the prosthesis was removed due to persistence of the infection or if uncontrolled symptoms were present. Results: In total, 302 patients were analysed. Two hundred and three of these patients (67.2%) received monotherapy. The most commonly used drugs were tetracyclines (39.7% of patients) (120/302) and cotrimoxazole (35.4% of patients) (107/302). SAT was considered successful in 58.6% (177/302) of the patients (median time administered, 36.5 months; IQR 20.75e59.25). Infection was controlled in 50% of patients at 5 years according to KaplaneMeier analysis. Resistance development was documented in 15 of 65 (23.1%) of the microbiologically documented cases. SAT failure was associated with age <70 years (sub-hazard ratio (SHR) 1.61, 95% CI 1.1e2.33), aetiology other than Gram-positive cocci (SHR 1.56, 95% CI 1.09e2.27) and location of the prosthesis in the upper limb (SHR 2.4, 95% CI 1.5e3.84). SAT suspension was necessary due to adverse effects in 17 of 302 patients (5.6%). Conclusions: SAT offers acceptable results for patients with PJI when surgical treatment is not performed or when it fails to eradicate the infection.

Background Maintenance ART with dolutegravir-based dual regimens have proved their efficacy among HIV-1-infected subjects in randomized trials. However, real-life data are scarce, with limited populations and follow-up. Objectives We assessed virological failure (VF) and resistance-associated mutations (RAMs) on dolutegravir maintenance regimens in combination with rilpivirine or with lamivudine or emtricitabine (xTC) and analysed the factors associated with VF. Methods Between 2014 and 2018, all HIV-1-infected adults included in the Dat’AIDS cohort and starting dolutegravir/rilpivirine or dolutegravir/xTC as a maintenance dolutegravir-based dual regimen were selected. VF was defined as two consecutive HIV RNA values &gt;50 copies/mL or a single value &gt;400 copies/mL. We compared cumulative genotypes before initiation of a maintenance dolutegravir-based dual regimen with genotype at VF. Results We analysed 1374 subjects (799 on dolutegravir/rilpivirine and 575 on dolutegravir/xTC) with a median follow-up of 20 months (IQR = 11–31) and 19 months (IQR = 11–31), respectively. VF occurred in 3.8% (n = 30) of dolutegravir/rilpivirine subjects and 2.6% (n = 15) of dolutegravir/xTC subjects. Among subjects receiving dolutegravir/rilpivirine, two genotypes harboured emerging RAMs at VF: E138K on NNRTI (n = 1); and E138K+K101E on NNRTI and N155H on INSTI (n = 1). Among subjects receiving dolutegravir/xTC, no new RAM was detected. The only predictive factor of VF on dolutegravir/rilpivirine was the history of failure on an NNRTI-based regimen (adjusted HR = 2.97, 95% CI = 1.28–6.93). No factor was associated with VF on dolutegravir/xTC. Conclusions In this large real-life cohort, dolutegravir/rilpivirine and dolutegravir/xTC sustained virological suppression and were associated with a low rate of VF and RAM emergence. Careful virological screening is essential before switching to dolutegravir/rilpivirine in virologically suppressed patients with a history of NNRTI therapy.

Background The arrival of highly effective, well tolerated direct-acting antiviral agents (DAA) led to a dramatic decrease in HCV prevalence. HIV-HCV coinfected patients are deemed a priority population for HCV elimination, while a rise of recently acquired HCV infections in MSM has been described. We describe the variations in HIV-HCV epidemiology in the French Dat’AIDS cohort. Methods Retrospective analysis of a prospective HIV-infected cohort from 2012 to 2018. Determination of HCV prevalence, incidence, proportion of viremic patients, treatment uptake and mortality rate in the full cohort and by HIV risk factors. Results From 2012 to 2018, 50861 HIV-infected patients with a known HCV status were followed-up. During the period, HCV prevalence decreased from 15.4% to 13.5%. HCV prevalence among new HIV cases increased from 1.9% to 3.5% in MSM but remained stable in other groups. Recently acquired HCV incidence increased from 0.36/100PY to 1.25/100PY in MSM. The proportion of viremic patients decreased from 67.0% to 8.9%. MSM became the first group of viremic patients in 2018 (37.9%). Recently acquired hepatitis represented 59.2% of viremic MSM in 2018. DAA treatment uptake increased from 11.4% to 61.5%. More treatments were initiated in MSM in 2018 (41.2%) than in IVDU (35.6%). In MSM, treatment at acute phase represented 30.0% of treatments in 2018. Conclusions A major shift in HCV epidemiology was observed in HIV-infected patients in France from 2012 to 2018, leading to a unique situation in which the major group of HCV transmission in 2018 was MSM.
