ABSTRACT

Novel coronavirus infection(COVID-19)has spread rapidly around the world since its emergence in 2019, with universal susceptibility of the population, causing hundreds of millions of infections and millions of deaths worldwide. Recently, the World Health Organization reconfirmed that COVID-19 is still a public health emergency of international concern. In order to ensure the early detection, identification and intervention of severe COVID-19 cases, reduce the disease severity and mortality, and further standardize the application of antiviral drugs for treatment, the National Center for Infectious Diseases (NCID) has invited experts to develop the Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( Trial version 10) in January 2023. The expert consensus is an important document that systematically reviews, summarizes and analyzes the application of antiviral drugs for COVID-19 from a multidisciplinary perspective for the first time, and can provide guidance and reference for medical institutions at all levels in the selection of antiviral drugs for COVID-19. This article aims to interpret the main points of the expert consensus, including the current epidemiological situation and pathogenic characters of novel coronavirus, clinical characteristics and classification of COVID-19, focusing on the antiviral therapy, guidance for home treatment and post-discharge management of patients with COVID-19.

ABSTRACT

The rationale for the antibiotic treatment of viral community-acquired pneumonia (CAP) in adults was analyzed to develop a clinical reference standard for this condition. Clinical data from 166 patients diagnosed with viral pneumonia across 14 hospitals in Beijing from November 2010 to December 2017 were collected. The indications for medications were evaluated, and the rationale for the use of antibiotics was analyzed. A total of 163 (98.3%) patients with viral pneumonia were treated with antibiotics. A combination of C-reactive protein (CRP) and procalcitonin (PCT) was used as markers to analyze the possible indications for antibiotic use. With threshold levels set at 0.25 µg/L for PCT and 20 mg/L for CRP, the rate of unreasonable use of antibiotics was 55.2%. By contrast, at a CRP level threshold of 60 mg/L, the rate of antibiotic misuse was 77.3%. A total of 39 of the 163 (23.9%) patients did not meet the guidelines for drug selection for viral CAP in adults. The unreasonable use of antibacterial drugs for the treatment of viral CAP in adults is a serious concern. Clinicians must reduce the unnecessary use of antibiotics.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the etiology of hand, foot and mouth disease (HFMD) in Beijing during 2013, and study the clinical characteristics of HFMD caused by the main serotypes of enterovirus in the study.</p><p><b>METHOD</b>Clinical data and 128 stool samples were collected from 128 hospitalized children with HFMD in Beijing Ditan Hospital during 2013. One step RT-PCR method was used for enterovirus genotyping to investigate the etiology of HFMD. Clinical characteristics of HFMD caused by the main serotypes of enterovirus were analyzed. And VP1 segments of the main virus were amplified to construct phylogenetic tree for the phylogenetic analysis.</p><p><b>RESULT</b>A total of 128 hospitalized children with HFMD were included. HFMD was more likely developed in children under 2 years of age (81.6%, 102/125); 11 different enteroviruses were genotyped, with a total enterovirus positive rate of 76.6% (98/128); the positive rate of coxsackievirus A6 (CA6), 43.0% ( 55/128), was the highest, followed by enterovirus 71 (EV71), accounting for 14.8% (19/128). HFMD caused by CA6 was atypical, the rashes of which involved the perioral, trunk, limbs, face and neck (47%, 26/55), besides the common parts. Of the 55 cases caused by CA6, 6 children had clinical manifestations of nervous system involvement, one of whom even displayed type 2 respiratory failure. Mental status change more likely to occur in EV71-infected children than in CA6-infected ones (42% (8/19) vs. 11% (6/55) (χ(2)=7.041, P=0.008)); 13 children displayed onychomadesis, including 12 CA6 cases (23%, 12/53) and 1 CA10 cases (17%, 1/6), in the convalescence of hand, foot and mouth disease, and the correlation between onychomadesis and CA6 infection was significant (χ(2)=9.297, P=0.002). Phylogenetic analysis of 33 CA6 VP1 showed that the CA6 isolates of this study were highly similar to that of Taiwan and the nucleotide similarity was 95.91%-98.89%.</p><p><b>CONCLUSION</b>CA6 was the major pathogen of hospitalized children with hand, foot and mouth disease in Beijing during 2013, followed by EV71. The rashes caused by CA6 involved a wide range of skin sites and patients with CA6 infection displayed manifestations of neurological involvement or pulmonary edema similar to EV71 infection. Mental status change more likely occurred in EV71-infected children when neurological system was involved..</p>

ABSTRACT

<p><b>BACKGROUND</b>Protectin D1 (PD1), derived from docosahexaenoic acid, has been shown to control and resolve inflammation in some experimental models of inflammatory disorders. We investigated the protective roles of protectin D1 in pulmonary inflammation and lung injury induced by lipopolysaccharide (LPS).</p><p><b>METHODS</b>Mice were randomly assigned to six groups (n = 6 per group): sham-vehicle group, sham-PD1 group, sham-zVAD-fmk group, LPS-vehicle group, LPS-PD1 group, and LPS-PD1-zVAD-fmk group. Mice were injected intratracheally with 3 mg/kg LPS or saline, followed 24 hours later by intravenous injection of 200 µg/mouse PD1 or vehicle. At the same time, some mice were also injected intraperitoneally with the pan-caspase inhibitor zVAD-fmk. Seventy-two hours after LPS challenge, samples of pulmonary tissue and bronchoalveolar lavage fluid were collected. Optical microscopy was used to examine pathological changes in lungs. Cellularity and protein concentration in bronchoalveolar lavage fluid were analyzed. Lung wet/dry ratios and myeloperoxidase activity were measured. Apoptosis of neutrophils in bronchoalveolar lavage fluid (BALF) was also evaluated by flow cytometry.</p><p><b>RESULTS</b>Intratracheal instillation of LPS increased neutrophil counts, protein concentration in bronchoalveolar lavage fluid and myeloperoxidase activity, it induced lung histological injury and edema, and also suppressed apoptosis of neutrophils in BALF. Posttreatment with PD1 inhibited LPS-evoked changes in BALF neutrophil counts and protein concentration and lung myeloperoxidase activity, with the outcome of decreased pulmonary edema and histological injury. In addition, PD1 promoted apoptosis of neutrophils in BALF. The beneficial effects of PD1 were blocked by zVAD-fmk.</p><p><b>CONCLUSION</b>Posttreatment with PD1 enhances resolution of lung inflammation during LPS-induced acute lung injury by enhancing apoptosis in emigrated neutrophils, which is, at least in part, caspase-dependent.</p>
