Objectives
Azvudine has been designated as a priority treatment for patients infected with SARS-CoV-2, however, clinical evidence in hospitalized cases remains insufficient.
Methods
We performed a multi-center, retrospective cohort study to evaluate the effectiveness and safety of azvudine in hospitalized patients with SARS-CoV-2 in China (NCT06349655). Kaplan-Meier method, Cox regression model, subgroup analysis, and seven sensitive analyses were employed.
Results
A total of 32864 hospitalized patients with SARS-CoV-2 were enrolled, in which 5735 azvudine recipients and 5735 controls were selected using 1:1 propensity score matching. Based on Kaplan-Meier analysis, azvudine significantly reduced rates of all-cause death (P < 0.0001) and composite disease progression (P = 0.00019). Cox regression analysis demonstrated that hazard ratios of all-cause death and composite disease progression were 0.68 (95%CI: 0.598–0.775, P < 0.001) and 0.88 (95% CI: 0.795–0.976, P = 0.016), respectively. Subgroup analysis showed preference of azvudine for patients receiving antibiotics in reducing all-cause death and composite disease progression. Seven sensitivity analyses verified the robustness of our results. Safety analysis on adverse events showed no significant difference between both groups.
Conclusions
This study suggested that azvudine may reduce all-cause death and composite disease progression in hospitalized patients with SARS-CoV-2 infection without serious adverse events. However, the findings are susceptible to some potential biases, and further studies still need to identify the efficacy of azvudine.

Objectives
PICOBOO is a randomised, adaptive trial evaluating the immunogenicity, reactogenicity, and safety of COVID-19 booster strategies. Here, we present data for second boosters among individuals aged 18-<50 and 50-<70 years old primed with BNT162b2 until Day (D) 84.
Methods
Immunocompetent adults who had received two doses of BNT162b2 and any licensed COVID-19 booster at least three months prior were eligible. Participants were randomly allocated to BNT162b2, mRNA-1273 or NVX-CoV2373 1:1:1. The log10 concentration of anti-spike Ig Total was summarised as the geometric mean concentration (GMC). Reactogenicity and safety outcomes were captured.
Results
Between Mar 2022 and Aug 2023, 743 participants were recruited to the trial and had D28 samples available. Of these, 120 and 103 belonged to the 18-<50 y and 50-<70 y strata, respectively. The mean adjusted GMCs (95% credible intervals) peaked at D28; these were 41 262 (31 611, 51 105), 45 585 (34 194, 57 441) and 25 281 (20 021, 31 234) U/mL in the 18-<50 y stratum and 30 753 (25 071, 36 704), 35 132 (27 523, 42 239) and 17 322 (13 983, 20 641) U/mL in the 50-<70 y stratum following BNT162b2, mRNA-1273 and NVX-CoV2373, respectively. Limited neutralisation against Omicron subvariants was found following boosting with all vaccines. There were 4 possibly or probably-related adverse events in the 18-<50 y stratum and 5 events in the 50-<70 y stratum, and severe reactogenicity events were <10% and <11% in these strata, respectively.
Conclusions
Vaccines targeting Ancestral virus elicited boosted antibody responses to Ancestral virus but minimal neutralising antibody against Omicron variants.

Tuberculosis (TB) is characterized by immunopathology in the blood and monocytes have been shown to be highly sensitive to plasma environment changes in TB patients. Here, we investigated TB plasma effects on ‘reference monocytes’ using RNA sequencing to characterize a potential immunomodulatory role of monocytes in TB. Candidate pathways induced by plasma samples from TB patients (n=99) compared to healthy controls (n=62) were analyzed for changes in signal transduction, phenotype and secreted cytokines by flow cytometry. Finally, potential implications were characterized in blood samples from corresponding patients and controls.
Reference monocytes treated with TB plasma showed an enrichment of pathways involved in inflammation and chemotaxis. Inflammatory cytokines were accompanied by enhanced phosphorylation of STAT molecules (i.e., STAT1/3/5), and strong positive correlations were detected for Interleukin (IL)-6 only in TB plasma-treated monocytes. Moreover, monocyte chemokine receptors (i.e., CCR-1, CCR-5) and pro-inflammatory chemokines (i.e., CXCL-1, CXCL-2, CXCL-8, G-CSF, CCL-2) that attract granulocytes and monocytes were significantly higher in TB plasma-treated monocytes. Notably, corresponding clinical samples also showed higher plasma levels for a subset of inflammatory cytokines/chemokines and, in particular, high IL-6 levels correlated positively with accumulation of neutrophil granulocytes in the blood of TB patients. Finally, monocytes from TB patients were characterized by increased chemokine receptor expression, higher proportions of a CCR-2+ subpopulation and aberrant high SOCS3 expression.
These results suggest that monocytes may play a significant role in amplifying plasma immunopathology, leading to sustained mobilization and accumulation of neutrophil granulocytes and chronic inflammation in the blood of TB patients.
