Humoral response 24 months after the first COVID-19 vaccination in people with HIV with and without diabetes.

People with HIV (PWH) and people with diabetes mellitus have increased risk of severe COVID-19, but little is known about humoral response to COVID-19 vaccines in PWH with DM. We investigated SARS-CoV-2 antireceptor-binding domain (anti-RBD) immunoglobulin G (IgG) geometrical concentrations and neutralizing antibody capacity (nAB) in PWH with and without diabetes mellitus. Anti-RBD IgG and nAB in COVID-19-vaccinated PWH were not associated with diabetes mellitus-status or HbA1c 24 months after the initial COVID-19 vaccination.

The impact of lower respiratory tract sample cultures on outcomes in community-acquired pneumonia: a propensity score matched cohort study.

Objectives: This study aimed to determine whether collecting a lower respiratory tract sample (LRTS) for bacterial microscopy, culture, and resistance (MCR) testing affects outcomes in patients with CAP.

Methods: A cohort study including adults admitted to hospital with CAP. The primary outcome was the duration of narrow-spectrum antibiotic treatment.

Susceptibility to and severity of SARS-CoV-2 infection according to prescription drug use-an observational study of 46,506 Danish healthcare workers.

It is not well investigated whether exposure to specific drug classes is associated with COVID-19. We investigated the risk of SARS-CoV-2 infection and severe COVID-19 among healthcare workers according to prescription drug use. We conducted an observational study among Danish healthcare workers.
