Comparative features of Asthma with frequent or infrequent exacerbations: A longitudinal study of retrospective and prospective events

Background: A “frequent exacerbator phenotype” has been described, mostly in the population of patients with severe asthma. Further data are needed on such exacerbation-prone patients in milder asthma. Aim: To compare the characteristics of frequent and nonfrequent exacerbators in asthma of different severities and to assess the stability of the exacerbator status. Methods: This was an observational study comparing baseline data from frequent (≥2 exacerbations in the past year) and nonfrequent (<2 exacerbations in the past year) exacerbators. Patients were also followed up for one year. Information regarding clinical, physiologic, and inflammatory characteristics was collected at baseline and one-year follow-up. Results: Forty-seven frequent and 53 nonfrequent exacerbators were recruited. No specific clinical, physiologic, or inflammatory characteristic was observed in the frequent as compared to the nonfrequent exacerbators at baseline. Fifty-eight percent of patients reporting frequent exacerbations at baseline remained in this group after one year of follow-up. Forty-two and 62% of patients with, respectively, mild-to-moderate asthma and severe asthma had frequent exacerbations. In a post hoc analysis according to asthma severity, frequent exacerbators with severe asthma had a higher body mass index and poorer asthma control, although they reported higher adherence to medication, in comparison to frequent exacerbators with mild-to-moderate asthma. No specific characteristics could discriminate between frequent and nonfrequent exacerbators of the same asthma severity. Conclusions: Frequent exacerbators with severe asthma present some specific characteristics not observed in frequent exacerbators with mild-to-moderate disease. However, the latter group should be identified to reassess treatment needs and potential contributing factors.     

Epidemiology of Confirmed COVID-19 Deaths in Adults,England, March–December 2020

Of the 58,186 coronavirus deaths among adults in England during March–December 2020, 77% occurred in hospitals, 93% were in patients >60 years, and 91% occurred within 28 days of positive specimen. Cumulative mortality rates were highest among persons of Black, Asian, other, or mixed ethnicities and in socioeconomically deprived areas.     

Difficulties in Differentiating Coronaviruses from Subcellular Structures in Human Tissues by Electron Microscopy

Efforts to combat the coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have placed a renewed focus on the use of transmission electron microscopy for identifying coronavirus in tissues. In attempts to attribute pathology of COVID-19 patients directly to tissue damage caused by SARS-CoV-2, investigators have inaccurately reported subcellular structures, including coated vesicles, multivesicular bodies, and vesiculating rough endoplasmic reticulum, as coronavirus particles. We describe morphologic features of coronavirus that distinguish it from subcellular structures, including particle size range (60–140 nm), intracellular particle location within membrane-bound vacuoles, and a nucleocapsid appearing in cross section as dense dots (6–12 nm) within the particles. In addition, although the characteristic spikes of coronaviruses may be visible on the virus surface, especially on extracellular particles, they are less evident in thin sections than in negative stain preparations.     

非抗菌疗法在泛耐药菌珠所致老年重症肺部感染疾病治疗中的可行性研究

目的：探讨非抗生素治疗手段在泛耐药菌珠所致老年重症肺部感染疾病治疗中的可行性。方法选取2010年4月－2012年9月机械通气患者81例，根据治疗方案不同将患者分为A组36例及B组45例。 A组治疗措施主要为应用胸腺肽类药物、丙种球蛋白免疫调节剂和血必净，每天进行1～2次的气管镜吸引及灌洗等。 B组在A组的基础上继续给予经验性抗生素治疗。比较2组APACHEⅡ评分、白细胞数、体温及耐药性。结果 A组患者致病菌的耐药性由原来的100．0％广泛耐药特性降至55．2％，而B组患者致病菌耐药性未见明显改变；而白细胞含量经过非抗生素处理干预治疗后的A组白细胞数量有所下降，且与治疗前比较差异有统计学意义（P＜0．05）。治疗1个月，A组死亡2例，病死率为5．6％，而B组死亡10例，病死率为22．2％，差异有统计学意义（P＜0．01）。结论非抗生素治疗可使患者致病菌耐药性下降，降低病死率，具有可行性。     

TTC7A mutation must be considered in patients with repeated intestinal atresia associated with early inflammatory bowel disease: Two new case reports and a literature review

TTC7A mutations cause multiple neonatal intestinal atresias with early inflammatory bowel disease and severe combined immunodeficiency. There are no treatment protocols for this rare disease. Two new cases are described for which radical early treatment measures – total enterectomy, home parenteral nutrition, immunoglobulin therapy and intravenous antibiotic prophylaxis – have allowed both patients to develop optimally.     

Rescue therapy: ciclosporin or infliximab?

Evaluation of: Laharie D, Bourreille A, Branche J et al.; Groupe d’Etudes Thérapeutiques des Affections Inflammatoires Digestives. Ciclosporin versus infliximab in patients with severe ulcerative colitis refractory to intravenous steroids: a parallel, open-label randomised controlled trial. Lancet 380(9857), 1909–1915 (2012).

Severe active refractory ulcerative colitis is a potentially life-threatening disease. The introduction of intensive steroid treatment and early surgery has reduced mortality in recent years. Ciclosporin and infliximab are effective rescue therapies in steroid refractory colitis. A head-to-head study proposed by Laharie et al. failed to demonstrate the superiority of ciclosporin but confirmed the efficacy and safety of infliximab to control active disease and to maintain remission.     

Management of severe bacterial infections

Defining the severity of an infection can play a central role for a correct therapeutic choice, avoiding inadequate antimicrobial treatments. Severe bacterial infections are, in fact, characterized by high morbidity and mortality rates so that the appropriateness of therapy can have a profound clinical impact. Indeed, initial inappropriate empirical therapies, and the further need to modify them, substantially increase the mortality risk. Several strategies have been suggested to improve the clinical outcome of patients affected by severe bacterial infections, such as the use of guidelines, use of antibiotics in combination, de-escalation therapy, cycling therapy and the use of infectious disease specialist consultation. A closer collaboration between the medical staff in the wards and infectious disease specialists can possibly bridge the gap between different strategies and individual needs of the patient, thereby improving the decision-making process.
