Association of the COVID-19 Pandemic with HbA1c Testing and Complication Screening in Patients with Diabetes Mellitus.
This study aimed to identify the association between coronavirus disease 2019 (COVID-19) transmission levels and undergoing glycated hemoglobin (HbA1c) test and complication screenings among patients with diabetes mellitus. ⋯ A high level of COVID-19 transmission was associated with a decrease in undergoing fundus examination and kidney disease screening. To fully realize the potential benefit of diabetes complication screenings, further effort is required to identify and address challenges to obtaining these screenings, especially in outbreak regions.

Longitudinal analysis of antibody responses following three-dose COVID-19 vaccination in patients with chronic liver disease (CLD) has been limited. From August 2021 to February 2023, sequential anti-SARS-CoV-2 spike IgG titers were determined in 45 patients with CLD who received two or three doses of COVID-19 vaccine. ⋯ The anti-spike IgG titers in participants receiving prime-boost homologous mRNA vaccines (BNT162b2 or mRNA-1273) were comparable between participants with and those without significant liver fibrosis at each follow-up time point. This study demonstrated a notable decrease in anti-spike IgG after completion of the vaccination schedule in patients with CLD, highlighting the importance of additional booster doses.
