in is not considered a K. pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) or a carbapenem-resistant K. pneumoniae (CRKP) as it is usually. Further follow-up and research are required to investigate this strain. Hepatitis E virus (HEV) is an emerging infectious agent that causes acute hepatitis in developing and developed countries. Diagnosis of HEV infection has not been routinely done in Egyptian hospitals, and clinicians do not prescribe ribavirin (RBV) for acute hepatitis cases of unknown etiology (AHUE). We aimed to screen patients with AHUE for the presence of HEV markers and to determine the complications associated with HEV infection. HEV markers (anti-HEV IgM, anti-HEV IgG, and HEV RNA) were assessed in patients with AHUE (n=300) admitted to Assiut University Hospitals. RT-qPCR was used to detect the viral load and sequencing analysis was carried out to determine the genotype of the detected viruses. Phylogenetic tree was constructed to evaluate the genetic relatedness between the isolates. Laboratory parameters and the outcomes of infection were determined. Acute HEV infection (AHE) was detected in 30 out of 300 (10%) of AHUE patients. Anti-HEV IgM, HEV RNA, and anti-HEV IgG were reported in 83%, 50%, diagnosis and treatment become pivotal in Egyptian hospitals to reduce the fatality rate and they should start urgently and promptly. To determine the phenotypes and genotypes of invasive ( ), 108 strains were isolated from paediatric patients with invasive pneumococcal diseases (IPDs) in Shenzhen from 2014 to 2018. Serotype profiles were defined by multiplex PCR of the capsule gene. Pneumococcal surface protein A (PspA) classification was performed through gene sequencing. Antimicrobial resistance was examined by broth microdilution. Multilocus sequence typing (MLST) was determined based on next-generation sequencing data. Eighty-one of 17 serotypes were finally collected. The coverage of the 13-conjugated polysaccharide vaccine (PCV13) was 88.9%. After the introduction of PCV13, the nonvaccine serotypes were added by serotypes 15b, 16F and 20. Vaccine serotype 3 increased by four serious cases. The pspA family 1 and pspA family 2 are predominant. The multiple drug resistance rate is 91.3%. None of the nonmeningitis isolates were resistant to penicillin, while 98.8% of all the isolates were resistant to erythromycin.

Toddlers with asthma suffer disproportionally more than school-aged children from exacerbations with emergency visits and hospital admissions despite inhaled corticosteroid (ICS) treatment. A recent trial for children ≤5 years showed tolerability of tiotropium and potential to reduce asthma-related events. We conducted a retrospective analysis of electronic outpatient records (2017‒2019) of children <6 years treated with ICS plus long-acting β -agonists (LABAs) plus tiotropium as an add-on for uncontrolled severe asthma. The primary endpoint was a comparison of systemic corticosteroid (SCS) prescriptions 6 months before and after ICS/LABA/tiotropium start. Secondary endpoints included physician visits, hospitalisations and antibiotic prescriptions. We compared outcomes with children without asthma matched for age, sex, season and screening date. Compared with a mean 2.42 (95% CI 1.75, 3.36) SCS courses per patient within 6 months prior to ICS/LABA/tiotropium, 0.74 (95% CI 0.25, 1.08) SCS courses per patient were prescribed within 6 months after starting ICS/LABA/tiotropium ( <0.001). Physician visits dropped from 9.23 (95% CI 7.15, 12.72) to 5.76 (95% CI 3.10, 7.70) per patient ( <0.01). Nineteen hospitalisations were recorded 6 months before ICS/LABA/tiotropium compared with one hospitalisation after ( <0.01). A mean 1.79 antibiotic courses (95% CI 1.22, 2.23) per patient were prescribed before ICS/LABA/tiotropium compared with 0.74 (95% CI 0.22, 1.00) after ICS/LABA/tiotropium ( <0.001). Hospitalisation rates for patients at observation end were not statistically different from healthy controls before/after matching. Our retrospective study showed that adding tiotropium to ICS/LABA is a new treatment option for patients with severe preschool asthma; however, larger confirmatory studies are needed.

Group 2 innate lymphoid cells (ILC2s) play crucial roles in type 2 immunity and asthma development. While ILC2s are resident in mucosal tissues, they also circulate in peripheral blood. It remains controversial whether ILC2s are increased in the peripheral blood of patients with asthma. The goal of this project was to study the effector functions of ILC2s in peripheral blood samples by in vitro culture with cytokines. Peripheral blood mononuclear cells (PBMCs) were collected from 11 adult patients with mild asthma and 12 healthy control subjects. The number of peripheral blood ILC2s in PBMCs was analyzed by flow cytometry. PBMCs were cultured with IL-33 and IL-25 without any antigens, and the amounts of type 2 cytokines in cell-free supernatants were analyzed by ELISA. In selected experiments, production of cytokines by ILC2s was analyzed by intracellular cytokine staining and flow cytometry. In response to either IL-33 or IL-25 stimulation, PBMCs from patients with mild asthma produced larger amounts of IL-5 and IL-13 than PBMCs from healthy control subjects. However, ILC2 numbers or proportions were not significantly different between these two groups. Flow cytometric analysis confirmed production of IL-5 by ILCs when stimulated with IL-33. In vitro culture of PBMCs with a cocktail of cytokines, such as either IL-33 or IL-25 plus IL-2, may provide a valuable tool to assess the effector functions of ILC2s and may serve as a biomarker for human asthma.
