Abstract

:COVID-19 is a world health emergency which may inevitably affect the management of a complex autoimmune disease such as systemic sclerosis (SSc). Several SSc patients are frail and, in this pandemic, need a careful protection. The COVID-19 infection might complicate the clinical scenario of interstitial lung disease (ILD) in SSc because it determines a severe pneumonia characterized by radiological features similar to SSc-ILD. The striking CT similarities between the 2 diseases make it difficult to distinguish a worsening of SSc-ILD from COVID-19-ILD superinfection. Moreover, other aspects, like isolation during lock down, may cause a significant psychological stress which will pile up on the already difficult contact with the patients for a routine check-up. Moreover, the drug shortage is a real problem in these times. For these reasons, the rheumatologist in daily clinical practice should carefully differentiate the possible COVID-19 infection in order to optimize the patient management. Therefore, the challenge in everyday life will be to achieve in due time the differential diagnosis as well as the long-term psychological impact.Key Points• SSc patients should be encouraged to continue their chronic therapy; in case of immunosuppressive therapy it must be discontinued for safety in case of COVID-19 infection.• Psychological support must be guaranteed to every SSc patients.• COVID-19 pneuminia is hard to distinguish from an interstitial lung disease due to SSc lung involvment.• Data sharing is fundamental for an optimal managment of SSc patients during COVID-19 pandemia.

摘要

: 新型冠状病毒肺炎是世界卫生紧急事件,可能不可避免地影响复杂自身免疫性疾病 (如系统性硬化症 (SSc)) 的管理。一些SSc患者身体虚弱,在这种大流行中,需要小心保护。新型冠状病毒肺炎感染可能使SSc中间质性肺病 (ILD) 的临床情况复杂化,因为它确定了以类似于SSc-ILD的放射学特征为特征的重症肺炎。这两种疾病之间惊人的CT相似性使得难以区分ssc-ild恶化与COVID-19-ILD重叠感染。此外,其他方面,如在锁定期间的隔离,可能导致显著的心理压力,这将堆积在已经难以与患者进行常规检查的接触上。此外,在这个时代,药物短缺是一个真正的问题。由于这些原因,风湿病医生在日常临床实践中应仔细区分可能的新型冠状病毒肺炎感染,以优化患者管理。因此,日常生活中的挑战将是在适当的时候实现鉴别诊断疾病以及长期的心理影响。要点 • 应该鼓励SSc患者继续他们的慢性治疗;在免疫抑制治疗的情况下,为了新型冠状病毒肺炎感染的情况下的安全性,必须停止。• 必须保证对每个SSc患者的心理支持。• 由于SSc肺受累,很难与间质性肺病区分新型冠状病毒肺炎。• 数据共享是在新型冠状病毒肺炎全血症期间对SSc患者进行最佳管理的基础。

METHODS::The antimicrobial functions of neutrophils are facilitated by a defensive armamentarium of proteins stored in granules, and by the formation of neutrophil extracellular traps (NETs). However, the toxic nature of these structures poses a threat to highly vascularized tissues, such as the lungs. Here, we identified a cell-intrinsic program that modified the neutrophil proteome in the circulation and caused the progressive loss of granule content and reduction of the NET-forming capacity. This program was driven by the receptor CXCR2 and by regulators of circadian cycles. As a consequence, lungs were protected from inflammatory injury at times of day or in mouse mutants in which granule content was low. Changes in the proteome, granule content and NET formation also occurred in human neutrophils, and correlated with the incidence and severity of respiratory distress in pneumonia patients. Our findings unveil a 'disarming' strategy of neutrophils that depletes protein stores to reduce the magnitude of inflammation.

METHODS::Pneumonia is a common respiratory infectious disease that involves the inflammation of the pulmonary parenchyma. Periodontal disease is widespread and correlated with pneumonia. However, the relationship between periodontal treatment and clinical infectious outcomes in patients with pneumonia has remained undetermined. The aim of this study was to investigate the association between periodontal treatment and the risk of pneumonia events in the Taiwanese population. A nationwide population-based cohort study was conducted using data from the Taiwanese National Health Insurance Research Database (NHIRD). A total of 49,400 chronic periodontitis patients who received periodontal treatment from 2001 to 2012 were selected. In addition, 49,400 healthy individuals without periodontal diseases were picked randomly from the general population after propensity score matching according to age, gender, monthly income, urbanization, and comorbidities. The Cox proportional hazard regression analysis was adopted to assess the hazard ratio (HR) of pneumonia between the periodontal treatment cohort and the comparison cohort. The average ages of the periodontal treatment and comparison groups were 44.25 ± 14.82 years and 44.15 ± 14.5 years, respectively. The follow up durations were 7.66 and 7.41 years for the periodontal treatment and comparison groups, respectively. We found 2504 and 1922 patients with newly diagnosed pneumonia in the comparison cohort and the periodontal treatment cohort, respectively. The Kaplan-Meier plot revealed that the cumulative incidence of pneumonia was significantly lower over the 12 year follow-up period in the periodontal treatment group (using the log-rank test, p < 0.001). In conclusion, this nationwide population-based study indicated that the patients with periodontal treatment exhibited a significantly lower risk of pneumonia than the general population.

METHODS:OBJECTIVE:To describe the treatment of community-acquired pneumonia (CAP) in children under five years in Tanzania. METHODS:Between January and December 2017, children aged 2-59 months with chest radiography-confirmed CAP were enrolled. The parents were interviewed to collect information on the patients and home-based medication. Clinical information was derived from the patient files. Nasopharyngeal swab and blood samples were collected for isolation of the causative pathogens. Swab samples were analysed by quantitative PCR whereas blood samples were tested using BacT/Alert 3D. RESULTS:Overall, 109 children with CAP were included in this analysis. Provision of care to most children was delayed (median = 4.6 days). A quarter (26.6%) were given unprescribed/leftover antibiotics at home. Only one child had positive bacterial culture. Referrals were associated with nasopharyngeal carriage of Streptococcus pneumoniae (p = 0.003) and Haemophilus influenzae (p = 0.004). Of all admitted children, more than a quarter (n = 29) did not need to be hospitalised and inappropriately received injectable instead of oral antibiotics. CONCLUSION:We found high rates of home treatment, particularly with antibiotics. Appropriate health care was delayed for most children because of home treatment. Efforts are needed at the community level to improve awareness of antimicrobial resistance.
