[Display omitted] Sanhan Huashi granules (SHG) demonstrated therapeutic effects against coronavirus disease 2019 (COVID-19) in observational studies. In order to compare the effectiveness and safety of SHG and nirmatrelvir–ritonavir in treating adults with mild-to-moderate COVID-19, we conducted a randomized, active-controlled, open-label, multi-center trial conducted between February and July in 2023. The patients were randomized in a 1:1 ratio to the SHG group and the nirmatrelvir–ritonavir group. A total of 400 participants were randomized, among which 200 participants ultimately received SHG and 198 received nirmatrelvir–ritonavir. The primary outcome was time to sustained clinical recovery through day 28. SHG significantly shortened the median time to sustained clinical recovery compared to nirmatrelvir–ritonavir (6.0 (95% CI, 5.0 to 6.0) vs. 8.0 (95% CI, 6.0 to 9.0) d; P = 0.001), particularly for individual symptoms including fever, sore throat, cough and fatigue. No participants in either group died and incidence of severe COVID-19 showed no difference between two groups. Participants who received nirmatrelvir–ritonavir demonstrated a higher rate of virus clearance on day 5 compared to those received SHG (46.4% (95% CI, 39.1 to 53.7) vs. 65.6% (95% CI, 58.3 to 72.4); P < 0.001). Most adverse events were mild in both groups. In summary, SHG was superior to nirmatrelvir–ritonavir in shortening the time to sustained clinical recovery in participants with mild-to-moderate COVID-19, despite a lower virus clearance rate observed after 5 d of treatment (Chinese Clinical Trial Registry Identifier: ChiCTR2300067872).

[Display omitted] Although hypervirulent Klebsiella pneumoniae (hvKP) can produce community-acquired infections that are fatal in young and adult hosts, such as pyogenic liver abscess, endophthalmitis, and meningitis, it has historically been susceptible to antibiotics. Carbapenem-resistant K. pneumoniae (CRKP) is usually associated with urinary tract infections acquired in hospitals, pneumonia, septicemias, and soft tissue infections. Outbreaks and quick spread of CRKP in hospitals have become a major challenge in public health due to the lack of effective antibacterial treatments. In the early stages of K. pneumoniae development, HvKP and CRKP first appear as distinct routes. However, the lines dividing the two pathotypes are vanishing currently, and the advent of carbapenem-resistant hypervirulent K. pneumoniae (CR-hvKP) is devastating as it is simultaneously multidrug-resistant, hypervirulent, and highly transmissible. Most CR-hvKP cases have been reported in Asian clinical settings, particularly in China. Typically, CR-hvKP develops when hvKP or CRKP acquires plasmids that carry either the carbapenem-resistance gene or the virulence gene. Alternatively, classic K. pneumoniae (cKP) may acquire a hybrid plasmid carrying both genes. In this review, we provide an overview of the key antimicrobial resistance mechanisms, virulence factors, clinical presentations, and outcomes associated with CR-hvKP infection. Additionally, we discuss the possible evolutionary processes and prevalence of CR-hvKP in China. Given the wide occurrence of CR-hvKP, continued surveillance and control measures of such organisms should be assigned a higher priority. [ABSTRACT FROM AUTHOR]
