METHODS: This was a multi-centre prospective cohort study at all sites participating in the Swiss HIV Cohort Study (SHCS). We calculated the Dat'AIDS score in PWH aged 60 years or older at their first visit between 1 January 2015 and 1 January 2020. People living with HIV-2 and those whose Dat'AIDS score could not be calculated were excluded. Patients were followed until 1 January 2020. The primary endpoint was all-cause mortality. Vital status was collected throughout the study period. We obtained population and score descriptive statistics and assessed the score's discrimination and calibration.
RESULTS: We included 2205 participants (82\% male) of median [interquartile range (IQR)] age 62.0 (60.3-67.0) years, mostly with viraemia {\textless}50 copies/mL (92.7\%). Median follow-up time was 15.9 years and median (IQR) CD4 cell count at enrolment was 586 (420-782) cells/μL. In all, 152 deaths were recorded during a total follow-up period of 7147 patient-years. The median (IQR) observed Dat'AIDS score was 3 (0-8). Discriminative capacities were good as the C-statistic was 0.73 (95\% CI: 0.69-0.77) and consistent across all subgroups.

OBJECTIVE: The PROPAGE study evaluated the interest of a strategy using serial measurements of procalcitonin (PCT) to reduce the duration of antibiotic therapy in old patients with pneumonia.
METHODS: PROPAGE took place from Dec.-2013 to Jun.-2016 in eight French geriatric units. It was a prospective, comparative, randomised, open-label study involving old patients (≥ 80 years) who had initiated antibiotic treatment for pneumonia in the previous 48 h. PCT was monitored in all patients and two decision-making PCT-based algorithms guided antibiotic therapy in patients from the PCT group.
RESULTS: 107 patients were randomised (PCT, n = 50; Control, n = 57). Antibiotic therapy exposure was reduced in the PCT group as compared to the Control group (median duration of antibiotic therapy, 8 vs. 10 days [rank-test, p = 0.001]; antibiotic persistence rates on Days 6 and 8, 54\% and 44\% vs. 91\% and 72\%) and no significant difference was found in recovery rate (84\% vs. 89.5\%; Pearson Chi² test, p = 0.402).
CONCLUSION: Although, the superiority of the strategy was not tested using a composite criterion combining antibiotic therapy duration and recovery rate was not tested due to the small sample size, the present study showed that monitoring associated with PCT-guided algorithm could help shorten antibiotic treatment duration in the very old patients without detrimental effects. Measuring PCT levels between Day 4 and Day 6 could be helpful when making the decision regarding antibiotic discontinuation.

DESIGN: Prospective observational multicentre study.
METHODS: Sixty-six physicians accepted to participate from 50 French Infectious Diseases and Geriatrics Departments. From May to September 2014, patients treated at least one day with SC antibiotics could be included. Modalities of subcutaneous administration, occurrence of local and systemic adverse effects (AE) and clinical course were collected until the end of the treatment.
RESULTS: Two hundred-nineteen patients (83.0 [19–104] yo) were included. Ceftriaxone (n = 163, 74.4\%), and ertapenem (n = 30, 13.7\%) were the most often prescribed antibiotics. The SC route was mainly used because of poor venous access (65.3\%) and/or palliative care (32.4\%). Fifty patients (22.8\%) experienced at least one local AE that led to an increased hospital stay for two patients (4.0\%) and a discontinuation of the SC infusion in six patients (12.0\%). A binary logistic regression for multivariate analysis identified the class of antibiotic (p = 0.002) especially teicoplanin and the use of rigid catheter (p = 0.009) as factors independently associated with AE. In over 80\% of cases, SC antibiotics were well tolerated and associated with clinical recovery.
CONCLUSIONS: SC administration of antibiotics leads to frequent but local and mild AE. Use of non-rigid catheter appears to be protective against AE. As it appears to be a safe alternative to the intravenous route, more studies are needed regarding efficacy and pharmacokinetics.},
