Abstract
Respiratory and gastrointestinal symptoms are the predominant clinical manifestations of the coronavirus disease 2019 (COVID-19). Infecting intestinal epithelial cells, the severe acute respiratory syndrome coronavirus-2 may impact on host's microbiota and gut inflammation. It is well established that an imbalanced intestinal microbiome can affect pulmonary function, modulating the host immune response ("gut-lung axis"). While effective vaccines and targeted drugs are being tested, alternative pathophysiology-based options to prevent and treat COVID-19 infection must be considered on top of the limited evidence-based therapy currently available. Addressing intestinal dysbiosis with a probiotic supplement may, therefore, be a sensible option to be evaluated, in addition to current best available medical treatments. Herein, we summed up pathophysiologic assumptions and current evidence regarding bacteriotherapy administration in preventing and treating COVID-19 pneumonia.

Abstract
Objective: In people living with HIV (PLWH), antiretroviral treatments have increased the median life expectancy. Raltegravir (RAL) represents a long-term safe regimen used both in the first-line antiretroviral treatments and in the optimization strategies. Aim of the study was to evaluate the real-life efficacy, tolerability, and safety of the long-term RAL use in a multicenter cohort of elderly PLWH.Methods: A 60-month follow-up observational study was carried out in the RAL-AGE Cohort including aged PLWH (≥60 years old) treated with RAL-based regimens (n = 96). The control group was a cohort of PLWH aged less than 60 years (n = 50).Results: RAL treated aged HIV population experiences an increase of CD4+ cells and a stable control of viral load at 60 months of follow-up. A significant improvement in lipid metabolism profile, a decrease of platelet count and a reduction in cardiovascular risk levels were observed in the older population. Immune activation markers expressed on CD4+ T cells decreased compared to baseline, but this difference was greater in the control group.Conclusion: A 60-month treatment with RAL-containing regimens is safe and highly effective in the older PLWH and these data give new insights on the elderly population.Clinical trial registration: NCT02765776 and NCT03579485.
