Background. This case-control study aims to investigate the clinical characteristics in pediatric patients with pneumonia infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza A, and human adenoviruses (HAdVs). Methods. Hospitalized pediatric patients with pneumonia infected with SARS-CoV-2 at Wuhan Children’s Hospital and pneumonia infected with influenza A, and HAdVs at Qilu Children’s Hospital were compared. Clinical manifestations, laboratory examinations, and imaging characteristics were analyzed. Results. The proportions of hyperpyrexia (54.3%, 33.9%), cough (100%, 99.2%), wheezing (45.7%, 53.7%), diarrhea (31.4%, 14.9%), and fever (100%, 75.2%) in patients with influenza A and HAdVs were higher than those of patients with SARS-CoV-2 (9.4%, P < .001; 48.5%, P < .001; 0%, P < .001; 8.8%, P = .002; 41.5%, P < .001; respectively). Laboratory examinations revealed the proportions of leukocytosis (37.1%, 52.9%), abnormal rates of neutrophils (40%, 40.5%), and lymphocytosis (42.9%, 65.3%) in influenza A and HAdV pneumonia groups were significantly higher than coronavirus disease 2019 (COVID-19) group (0%, P < .001; 0%, P < .001; 0%, P < .001; respectively). The proportion of elevated procalcitonin (5.7%, 14%) in patients with influenza A and HAdVs was significantly lower than those in patients with SARS-CoV-2 (64%, P < .001). In chest computed tomography, ground-glass opacities near the pleura were more common in patients with COVID-19 than those in patients with influenza A and HAdVs (32.7% vs 0% vs 0%, P < .001). Conclusion. Fever, cough, and wheezing are more common in the influenza A and HAdVs groups, whereas procalcitonin and computed tomography findings are likely to be pronounced in COVID-19 pneumonia. It provides a variety of methods except polymerase chain reaction for differentiating COVID-19 pneumonia from influenza A and HAdVs pneumonia.

Background: Infusion reactions (IRs) are the most common adverse events (AEs) of infliximab (IFX) treatment in patients with inflammatory bowel disease (IBD). Prophylactic premedication (PM) with corticosteroids or antihistamines prior to IFX infusions has been used in clinical practice, but its efficacy is not known. The aim of this study was to assess the influence of steroid PM on IR incidence in pediatric patients with IBD receiving IFX. Methods: We performed a case–control study that included pediatric patients with IBD receiving IFX. Patients were divided into four subgroups according to the agent and PM they received: Remicade (original drug) + PM, and two biosimilars—Reshma +/− PM, and Flixabi—PM. At our site, until 2018, PM with steroids was used as a part of standard IFX infusion (PM+); however, since then, this method has no longer been administered (PM−). IRs were divided into mild/severe reactions. Differences between subgroups were assessed with the appropriate chi-square test. Multivariate logistic regression was used to assess associations between PM and IR incidence, correcting for co-medication usage. Results: There were 105 children (55 PM+, 44 male, mean age 15 years) included in the study who received 1276 infusions. There was no difference between the PM+ and PM− subgroups, either in incidence of IR (18.2% vs. 16.0% of patients, p > 0.05) or in percentage of infusions followed by IR (2.02% vs. 1.02% of infusions, p > 0.5). The OR of developing IR when using PM was 0.34, and the difference in IRs ratio in PM+ and PM− patients was not statistically significant (95% CI, 0.034–1.9). There were 11/18 (61.1%) severe IRs (anaphylactic shock) reported in all patients (both PM+ and PM−). Conclusion: At our site, the incidence of IR was low, and PM did not decrease the incidence of IR in pediatric patients with IBD receiving IFX. These results indicate that PM with steroids should not be a standard part of IFX infusion to prevent IR.

Abstract Background The importance of influenza is increasing mainly because of the appearance of novel pandemic strains such as swine and avian. Each year, influenza has spread around the world causing about 250,000–500,000 deaths and more than 5 million cases of severe illness. The objective is as follows: evaluating the outcomes of patients with influenza A (H1N1) virus in relation to certain TNF-308, IL6, and IL8 polymorphisms and identifying the associated factors with the severe outcome. Subject and methods This is a case–control study. The cases were patients confirmed by real-time polymerase chain reaction (RT-PCR) to be influenza A (H1N1) virus infected. The controls were healthy individuals. Medical history and outcome of the disease was registered. In all study participants, polymorphisms of TNF rs1800629, IL6 rs18138879, and IL8 rs4073; odds ratio (OR); and the 95% confidence interval (95% CI) were calculated. Results Infection with influenza A (H1N1) virus was associated more with the following genotypes: TNF-308 AA (OR = 4.041; 95% CI = 1.215–13.4) and IL8 AA (OR = 3.273; 95% CI = 1.372–7.805). According to our study results, HCV (OR = 3.2, 95% CI 1.2–8.5), renal disease (OR = 3.4, 95% CI 0.9–13.6), cancer (OR = 3.1, 95% CI 0.3–31.1), TB (OR = 8.4, 95% CI 1.8–39.7), ICU (OR = 2.9, 95%1.2–7.1), and mortality (OR = 7.9, 95% CI 0.9–67.4) are considered as risk factors for influenza A (H1N1)-infected patients. Conclusions Our findings concluded that TNF-308 (AA) and IL8 (AA) polymorphisms may increase the susceptibility to be infected with H1N1influenza virus.
