Protecting health-care workers from subclinical coronavirus infectionHealth-care workers face an elevated risk of exposure to infectious diseases, including the novel coronavirus in China. It is imperative to ensure the safety of healthcare workers not only to safeguard continuous patient care but also to ensure they do not transmit the virus. COVID-19 can spread via cough or respiratory droplets, contact with bodily fluids, or from contaminated surfaces. 1 According to recent guidelines from the China National Health Commission, pneumonia caused by COVID-19 was included as a Group B infectious disease, which is in the same category as other infectious viruses such as severe acute respiratory syndrome (SARS) and highly patho genic avian influenza (HPAI). How ever, current guidelines suggest ensuring protective measures for all health-care workers similar to those indicated for Group A infections-a category reserved for highly infectious pathogens, such as cholera and plague. 2 WHO confirmed 8098 cases and 774 (9•6%) deaths during the SARS outbreak in 2002, of which health-care workers accounted for 1707 (21%) cases.Recent evidence suggests that even someone who is non-symptomatic can spread COVID-19 with high efficiency, and conventional measures of protection, such as face masks,
Background The spread of a highly pathogenic, novel coronavirus (SARS-CoV-2) has emerged as a once-in-a-century pandemic, having already infected over 63 million people worldwide. Novel therapies are urgently needed. Janus kinase-inhibitors and Type I interferons have emerged as potential antiviral candidates for COVID-19 patients due to their proven efficacy against diseases with excessive cytokine release and their direct antiviral ability against viruses including coronaviruses, respectively. Methods A search of MEDLINE and MedRxiv was conducted by three investigators from inception until July 30th 2020 and included any study type that compared treatment outcomes of humans treated with Janus kinase-inhibitor or Type I interferon against controls. Inclusion necessitated data with clearly indicated risk estimates or those that permitted their back-calculation. Outcomes were synthesized using RevMan. Results Of 733 searched studies, we included four randomized and eleven non-randomized trials. Five of the studies were unpublished. Those who received Janus kinase-inhibitor had significantly reduced odds of mortality (OR, 0.12; 95% CI, 0.03–0.39, p< 0.001) and ICU admission (OR, 0.05; 95% CI, 0.01–0.26, p< 0.001), and had significantly increased odds of hospital discharge (OR, 22.76; 95% CI, 10.68–48.54, p< 0.00001) when compared to standard treatment group. Type I interferon recipients had significantly reduced odds of mortality (OR, 0.19; 95% CI, 0.04–0.85, p< 0.05), and increased odds of discharge bordering significance (OR, 1.89; 95% CI, 1.00–3.59, p=0.05). Conclusions Janus kinase-inhibitor treatment is significantly associated with positive clinical outcomes in terms of mortality, ICU admission, and discharge. Type I interferon treatment is associated with positive clinical outcomes in regard to mortality and discharge. While these data show promise, additional well-conducted RCTs are needed to further elucidate the relationship between clinical outcomes and Janus kinase-inhibitors and Type I interferons in COVID-19 patients.
The rates of asthma and obesity are increasing concurrently in the United States. Epidemiologic studies demonstrate that the incidence of asthma increases with obesity. Furthermore, obese individuals have asthma that is more severe, harder to control, and resistant to standard medications. In fact, specific asthma-obesity phenotypes have been identified. Various pathophysiologic mechanisms, including mechanical, inflammatory, metabolic and microbiome-associated, are at play in promulgating the obese-asthma phenotypes. While standard asthma medications, such as inhaled corticosteroids and biologics, are currently used to treat obese asthmatics, they may have limited effectiveness. Targeting the underlying aberrant processes, such as addressing steroid resistance, microbiome, metabolic and weight loss approaches, may be helpful.
Background Novel coronavirus (SARS-CoV-2) has infected over 17 million. Novel therapies are urgently needed. Janus-kinase (JAK) inhibitors and Type I interferons have emerged as potential antiviral candidates for COVID-19 patients for their proven efficacy against diseases with excessive cytokine release and by their ability to promote viral clearance in past coronaviruses, respectively. We conducted a systemic review and meta-analysis to evaluate role of these therapies in COVID-19 patients. Methods MEDLINE and MedRxiv were searched until July 30th, 2020, including studies that compared treatment outcomes of humans treated with JAK-inhibitor or Type I interferon against controls. Inclusion necessitated data with clear risk estimates or those that permitted back-calculation. Results We searched 733 studies, ultimately including four randomized and eleven non-randomized clinical trials. JAK-inhibitor recipients had significantly reduced odds of mortality (OR, 0.12; 95%CI, 0.03-0.39, p=0.0005) and ICU admission (OR, 0.05; 95%CI, 0.01-0.26, p=0.0005), and had significantly increased odds of hospital discharge (OR, 22.76; 95%CI, 10.68-48.54, p<0.00001), when compared to standard treatment group. Type I interferon recipients had significantly reduced odds of mortality (OR, 0.19; 95%CI, 0.04-0.85, p=0.03), and increased odds of discharge bordering significance (OR, 1.89; 95%CI, 1.00-3.59, p=0.05). Conclusions JAK-inhibitor treatment is significantly associated with positive clinical outcomes regarding mortality, ICU admission, and discharge. Type I interferon treatment is associated with positive clinical outcomes regarding mortality and discharge. While these data show promise, additional randomized clinical trials are needed to further elucidate the efficacy of JAK-inhibitors and Type I interferons and clinical outcomes in COVID-19.
