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.

INTRODUCTION: Point-of-care ultrasonography (POCUS) has emerged as an essential supplement to physical examination in many specialties. In contrast, its use by infectious diseases (ID) specialists remains anecdotal. Here, we report on the acquisition of an ultrasonography device in a French ID ward, and we describe its everyday use. METHODS: A preliminary audit was conducted to evaluate the potential impact of the acquisition of an ultrasonography device. A second audit was performed during the first year following the acquisition of the device to quantify its everyday use. We also evaluated the impact of POCUS implementation on medical imaging requests by comparing the number of intra-hospital transports before and after the acquisition. RESULTS: According to the first audit, 81 of the 199 (41%) imaging examinations that were prescribed during a two-month period could have been replaced by POCUS. During the first year following the acquisition of the ultrasonography device, POCUS was performed 240 times by 31 different operators. The operators were a senior physician, an intern, and a medical student in 94 (39%), 135 (57%), and 11 (5%) cases, respectively. The organs most frequently explored were the genito-urinary tract (n=74), the joints (n=35), and the lungs/pleura (n=35). Acquisition of the device was followed by a significant decrease in the number of transports to the ultrasonography room, whereas the total number of transports to the medical imaging ward did not change. CONCLUSION: Opportunities to use POCUS in the ID ward are numerous. POCUS training should be part of the ID specialist's curriculum.

Aim: To assess the effect of colistin-glycopeptide combination against a multidrug-resistant strain of Acinetobacter baumannii. Materials & methods: We used in vitro procedures (Etest method, checkerboard test and kill-time assays) and a mouse model of a carbapenem-resistant A. baumannii pneumonia. Results: The colistin-teicoplanin combination allowed a 74% increase of the survival in the mouse model within the 4 days following bacterial inoculation as compared with saline or colistin alone (p = 0.06). Concurrently, the colistin-vancomycin combination presented a similar efficacy as compared with saline or colistin alone in the mouse model. Conclusion: According to those preliminary results, using the colistin-teicoplanin combination in therapeutic deadlocks encountered in certain multiresistant A. baumannii pneumonia could be envisaged if the results are confirmed.
