The safety of BCG revaccination in the context of COVID-19.

The bacille Calmette-Guérin (BCG) vaccine is administered in many countries as part of their vaccination schedules. Epidemiologic studies have suggested a possible benefit of this vaccine in the context of the COVID-19 pandemic and other respiratory infections. We aimed to assess the safety of this intervention in BCG-primed adults.

Serological follow up of positive SARS-CoV-2 cases.

Objective: To describe the humoral response in a cohort with mild and asymptomatic SARS-CoV-2 infection previ-ously identified in a community-based serological survey.

Materials And Methods: This study was an observational follow up of 193 subjects previously identified with positive anti-SARS-CoV-2 antibodies invited for a second test 112 days after the first sampling. All completed a standardized electronic questionnaire.

Adrenal functional reserve in the full spectrum of chronic kidney disease.

Background: Altered cortisol levels have been associated with an increase in mortality and a decrease in health-related quality of life in patients with chronic kidney disease (CKD); however, adrenal response to adrenocorticotropic hormone (ACTH) stimulation test has not been evaluated in patients with stage 3a to 5 CKD with and without renal replacement therapy (RRT).

Objective: To evaluate adrenal function in patients with CKD.

Materials And Methods: Adults with CKD underwent a low-dose cosyntropin stimulation test (1 µg synthetic ACTH), with serum cortisol levels being measured at 0, +30 and +60 minutes post-test.
