Objective: Application of realtime RT-PCR and conventional RT-PCR for detection of RSV in viral respiratory infections. Methods: Realtime RT-PCR and conventional nested RT-PCR were used to detect RSV on 110 respiratory samples collected from children with viral lower respiratory infections. Results: The data from the patients, whose samples were collected, showed that lower respiratory tract infections included bronchitis, bronchiolitis and pneumonia and that the mean of patient age was below 2 year old, among which, the negative RSV group of patients was 1.9 ±1.7 and the positive RSV group was 1.6 ± 1.4 years of age. The mean of time period from the onset of infections to sample collection was from 3.3 to 3.4 days. Realtime RT-PCR produced the same results as that of conventional RT-PCR. Conclusion: Realtime RT-PCR is rapid and closed-tube procedure; it should be used for detection of RSV in acute respiratory infections. Keywords: RSV, realtime RT-PCR, conventional RT-PCR

AbstractRespiratory tract infections require early diagnosis and adequate treatment. With the antibiotic overuse and increment in antibiotic resistance there is an increased need to accurately distinguish between bacterial and viral infections. We investigated the diagnostic performance of calprotectin in respiratory tract infections and compared it with the performance of heparin binding protein (HBP) and procalcitonin (PCT). Biomarkers were analyzed in patients with viral respiratory infections and patients with bacterial pneumonia, mycoplasma pneumonia and streptococcal tonsillitis (n = 135). Results were compared with values obtained from 144 healthy controls. All biomarkers were elevated in bacterial and viral infections compared to healthy controls. Calprotectin was significantly increased in patients with bacterial infections; bacterial pneumonia, mycoplasma pneumonia and streptococcal tonsillitis compared with viral infections. PCT was significantly elevated in patients with bacterial pneumonia compared to viral infections but not in streptococcal tonsillitis or mycoplasma caused infections. HBP was not able to distinguish between bacterial and viral causes of infections. The overall clinical performance of calprotectin in the distinction between bacterial and viral respiratory infections, including mycoplasma was greater than performance of PCT and HBP. Rapid determination of calprotectin may improve the management of respiratory tract infections and allow more precise diagnosis and selective use of antibiotics.

Abstract Background Viral respiratory infections are a major cause of hospitalization and intensive care unit (ICU) admission to children’s hospitals. Rates of respiratory syncytial virus (RSV) and influenza are closely tracked due to their known morbidity. We had previously observed over one season that human metapneumovirus (hMPV)-infected children have high rates of hospitalizations and ICU admissions, particularly those with chronic lung disease (CLD). We expanded our data to include an additional 5 seasons to compare rates of hospitalizations and hospital-acquired infections (HAIs) due to hMPV, RSV and influenza. Methods During the 2014–2019 winter viral seasons, hMPV, RSV and influenza infections were tracked through both PCR testing (Biofire Respiratory Panel) and DFA testing (D3 Ultra DFA Respiratory Virus Screening & ID Kit; Diagnostic Hybrids). For hMPV admissions, rates of hospitalizations, ICU admissions, HAIs and mortalities were assessed and compared with RSV and influenza admissions. Retrospective data were used to study patients infected with hMPV. Results During the winter seasons of 2014–2019, the rates of hospitalization due to hMPV were significantly higher than both RSV and influenza (Figure 1). ICU admissions and HAIs for hMPV were similar to RSV and influenza (Figures 2 and 3). There were 9 deaths over this time period; 5 due to RSV, 3 due to influenza and 1 due to hMPV. The proportion of deaths due to hMPV compared with RSV and influenza was similar (P = 0.54, 0.89, respectively). Of the 315 total admissions with hMPV, 43 (13.7%) had CLD and 13 (4.1%) were tracheostomy dependent. Among 67 hMPV ICU admissions from 2014–2019, 56 (84%) had an underlying medical diagnosis, 25 (37%) had CLD, 13 (19%) had tracheostomies, and 17 (25%) required mechanical ventilation. The average age of hMPV infected children in our ICU is 4 years 1 month. Conclusion Our large descriptive study of hMPV-infected children over 6 seasons showed higher rates of hospitalization compared with RSV and influenza, similar ICU and HAI rates, and similar rates of mortality. ICU admitted children often had associated co-morbidities, including CLD. Further studies for focused disease surveillance and potential vaccine development for high-risk children are needed.

ABSTRACT Viruses that cause respiratory tract infections are the most common agents of infectious diseases in humans throughout the world. A virus that infects the respiratory system, may induce various clinical symptoms. What is more, the same symptoms may be caused by different viruses. The aim of the study was to analyze the prevalence of enteroviruses that cause respiratory infections in patients with influenzavirus A/H1N1 hospitalized in the Lublin province. The experimental material was throat and nose swabs taken from patients hospitalized in Lublin and Tomaszow Lubelski. In the group of 44 patients (20 women and 24 men) infected with influenza A/H1N1, the genetic material of enteroviruses was detected in 13 patients (29.5%). Respiratory viruses co-infections are very common in hospitalized patients. Studies show that co-infection with influenza virus and enterovirus are more common in children than in adults. Moreover, viral respiratory tract infections are independent from the patients’ gender.

Since December 2019, a global pandemic has been observed, caused by the emergence of a new coronavirus, SARS CoV-2. The latter is responsible for the respiratory disease, COVID-19. The infection is also characterized by renal, hepatic, and gastrointestinal dysfunctions suggesting the spread of the virus to other organs. A dysregulated immune response was also reported. To date, there is no measure to treat or prevent SARS CoV-2 infection. Additionally, as gut microbiota composition is altered in patients with COVID-19, alternative therapies using probiotics can be considered to fight SARS CoV-2 infection. This review aims at summarizing the current knowledge about next-generation probiotics (NGPs) and their benefits in viral respiratory tract infections and in COVID-19. We describe these bacteria, highlighted by studies using metagenomic approaches. In addition, these bacteria generate metabolites such as butyrate, desaminotyrosine, and secondary bile acid, suggested to prevent viral respiratory infections. Gut microbial metabolites transported via the circulation to the lungs could inhibit viral replication or improve the immune response against viruses. The use of probiotics and/or their metabolites may target either the virus itself and/or the immunologic process. However, this review showed that more studies are needed to determine the benefits of probiotics and metabolite products in COVID-19.

Introduction: Whooping cough-like respiratory tract infections (WCLRTI) caused by factors other than the Bordetella pertussis are available. Clinical picture is difficult to differentiate between the B. pertussis and viral respiratory infections. Methodology: Eighty-five patients with the diagnosis of WCLRTI were divided into 3 groups. Group 1 involved patients with pertussis shown by nasopharyngeal aspirate culture (NAC) and/or PCR. Group 2 consisted of patients who B. pertussis was not detected by NAC however, clinicians still evaluated them as potential patients of pertussis. Group 3 involved patients with the diagnosis of WCLRTI and those with VRTI detected by antigen detection/PCR. Results: Patients with pertussis had longer duration of the symptoms prior to admission. Paroxysmal cough, whooping, vomiting after coughing, cyanosis, apnea, seizures and abdominal hernias were more common in patients with pertussis. Fever, wheezing, tachypnea, retraction, fine crackles and rhonchi were more common in Group 3. Chest radiographs of patients in Group 3 revealed more bronchopneumonic infiltration, increased aeration, and atelectasis. CRP (C-reactive protein) and ESR (erythrocyte sedimentation rate) were significantly higher in Group 3. Of the patients 43.6% had no pertussis vaccination due to being < 2 months in age and 29.4% had 1 dose. Conclusions: Pertussis should be thought in differential diagnosis of children with complaints of episodes of paroxysmal cough, cough accompanied by gasping, vomiting after coughing; with leukocytosis, lymphocytosis and a normal chest X-ray. The majority of children with pertussis infection are those who have not had the opportunity for vaccination.

Abstract Background Viral respiratory tract infections (VRTI) accounts for a significant proportion of hospitalized children and contributes to a substantial use of health care resources and costs. American Academy of Pediatrics (AAP) recommends against using antibiotics in uncomplicated viral respiratory infections in children. Overuse of antibiotics ranges between 29–80%. The goal of an Antibiotic stewardship programs (ASP) is to decrease antibiotic misuse, lower costs, and prevent emergence of antibiotic resistance in the community. Proportion of children with Viral respiratory tract infections on antibiotics Methods Our smart aim was to reduce antibiotic use by 25% in admitted children with VRTI between October 2019-March 2020. Our outcome measure was to reduce inappropriate antibiotic use during the 2019–20 season by 25%. Process measures included percentage of antibiotic used in viral RTI, antibiotic days of therapy and appropriate audit-feedback from the ASP team to facilitate discontinuation or de-escalation of antibiotics based on culture data. Our balance measure included readmission rates in patients in whom antibiotics were discontinued or de-escalated. Several PDSA cycles implemented with predominant emphasis on communication between ASP team and primary providers. Results No differences were noted in patient demographics including sex, age, ethnicity between the viral season in 2018–19 and 2019–2020. In our previous study in 2018–2019 RSV season, there was 40.7% antibiotic use in patients admitted with RSV bronchiolitis. In 2019–2020 season we included all patients admitted with viral RTI. Of the 213 patients evaluated between October 2019 through Dec 2020, 40% of the patients received antibiotics. 100% of the antibiotics were justified, based on independent review of antibiotic data by the team. Most common cause of antibiotics were community acquired pneumonia, rule out sepsis and otitis media. Antibiotic discontinuation and de-escalation were achieved in over 90% of the justified antibiotics. Conclusion Though antibiotic usage was still at 40% at our institution, 100% of antibiotic use was deemed appropriate and significant proportion were discontinued or deescalated by the ASP team. The ASP team played a crucial role in communicating with the primary providers to advocate for appropriate antibiotic use in the children. Disclosures All Authors: No reported disclosures
