To assess the efficacy of corticosteroids in patients with coronavirus disease 2019 (COVID-19).

A multicentre observational study was performed from 22 February through 30 June 2020. We included consecutive adult patients with severe COVID-19, defined as respiratory rate ≥30 breath per minute, oxygen saturation ≤93% on ambient air or arterial partial pressure of oxygen to fraction of inspired oxygen ≤300mm Hg. We excluded patients being treated with other immunomodulant drugs, receiving low-dose corticosteroids and receiving corticosteroids 72hours after admission. The primary endpoint was 30-day mortality from hospital admission. The main exposure variable was corticosteroid therapy at a dose of ≥0.5 mg/kg of prednisone equivalents. It was introduced as binomial covariate in a logistic regression model for the primary endpoint and inverse probability of treatment weighting using the propensity score.

Of 1717 patients with COVID-19 evaluated, 513 were included in the study, and of these, 170 (33%) were mortality might be limited to critically ill COVID-19 patients.
The efficacy of 13-valent pneumococcal conjugate vaccine (PCV13) in adults to prevent community-acquired pneumonia (CAP) and lower respiratory tract infections (LRTI) not requiring hospitalization is unknown. We determined the effect of PCV13 on CAP, LRTI and antibiotic use in the primary care setting.

Community-dwelling immunocompetent adults over 65years of age were randomized to PCV13 or placebo as part of the double-blind Community-Acquired Pneumonia immunization Trial in Adults (CAPiTA). CAP and LRTI episodes and antibiotic prescription data were extracted from general practitioner information systems of 40426 individuals. Vaccine efficacy (VE) of PCV13 was determined using Poisson regression with robust standard errors, comparing CAP and non-CAP LRTI episodes, LRTI-specific and total antibiotic prescriptions.

In all, 20195 participants received PCV13 and 20231 received placebo. A total of 1564 and 1659 CAP episodes occurred in the PCV13 and placebo group, respectively; VE 5.5% (95% CI -2.6% to 13.0%). Non-CAP LRTI episodes occurred 7535 and 7817 times in the PCV13 and placebo groups, respectively; VE 3.4% (95% CI -2.0% to 8.5%). A total of 8835 and 9245 LRTI-related antibiotic courses were prescribed in the PCV13 and placebo arms, respectively; VE 4.2% (95% CI -1.0% to 9.1%). Antibiotic courses for any indication were prescribed 43386 and 43309 times, respectively; VE -0.4% (-4.9% to 3.9%).

PCV13 vaccination in the elderly is unlikely to cause a relevant reduction in the incidence of CAP, LRTI, LRTI-related antibiotic use or total antibiotic use in primary care.

High risk healthcare workers (HCWs) are often screened for latent tuberculosis infection (LTBI) using QuantiFERON tests (QFTs), with annual serial tests often showing reversion from positive to negative results. We assessed the frequency of and risk factors for reversion of QFTs in HCWs in an intermediate-tuberculosis burden country.

We enrolled high risk HCWs at a tertiary-care hospital in South Korea, who were assessed by QFTs at least twice between 2017 and 2019.

Of the 1,870 HCWs screened, 1,542 (82%) had persistent negative results, 229 (12%) had persistent positive results, 53 (3%) showed reversion, and 46 (2%) showed conversion from negative to positive. Multivariate analysis comparing the characteristics of the 229 HCWs with persistent positive results and the 53 who experienced reversion showed that older age (adjusted odds ratio [aOR] 0.96; 95% CI 0.92-0.99), male sex (aOR 0.29; 95% CI 0.11-0.78) and high (≥0.70 IU/ml) baseline QFT results (aOR 0.15; 95% CI 0.07-0.31) were inversely associated with reversion. Using a ROC curve-derived cut-off of < 0.738 IU/ml, the area under the curve was 0.79. Of 53 HCWs with reversion, 36 (78%) had below 0.738 IU/mL of baseline QFT, while 181 (79%) of 229 HCWs without reversion had above 0.738 IU/mL of baseline QFT.

Reversion during serial testing is unlikely in HCWs who are male, older in age, and have higher baseline QFT results. Serial testing without LTBI treatment may be indicated in HCWs who are female, younger, and, especially, have lower QFT results.

However, studies which detect MCPyV DNA in blood products may reveal the importance of this virus for the transfusion medicine. In this study we analyzed by viral metagenomics 36 plasma samples obtained from blood donors positive for the common blood transmitted infections from the city of Macapá (Brazilian Amazon). The generated raw data were were analyzed through a specific bioinformatics pipeline aimed at discovery of emerging viruses. The genomes of interest were analyzed phylogeographically and phylogenetically. MCPyV complete genome was recovered from one HBV-positive pool with high coverage (~ 223×) indicating acute viremia or reactivated infection. Interestingly, the phylogeographic position of the identified strain suggests its ancestry compared to MCPyV isolate from Colombian Amazon which hypothesizes that viral dissemination in the Amazon may have originated from Brazil. CBL0137 order In conclusion, this study brings information for the genetic relationships of MCPyV isolated from blood donors from the Brazilian Amazon and demonstrates the possible phylogeographic behavior of our strain in relation to the other findings. We also demonstrated a strong evidence of viremic MCPyV phase in blood donations, however, more studies are necessary in order to understand the MCPyV impact on transfusion therapy.
