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 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.

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

Abstract Background: Respiratory viruses are the main pathogens of acute respiratory infections. Viral respiratory pathogens in children are well studied, but the study on adults are limited. So we design this subject to determine viral respiratory pathogens in patients with acute respiratory tract infections of adults. Methods: We conducted a retrospective study for the patients with acute respiratory infections from June, 2017 through July, 2018 at Fever Clinic in Peking University Third Hospital. We collected throat swab from the patients diagnosed with acute upper respiratory tract infections and sputum or throat swab diagnosed with community-acquired pneumonia. RT-PCRs were performed to detect infection with the following virus: human rhinovirus, influenza A virus, influenza B virus, human coronavirus 229E/HKU1，Coronavirus OC43/NL63、ADV, RSV, PIV1-4, hMPV and EV. Results：185 throat swabs and sputum were collected from outpatients. Overall, 23.8% (44/185) were found to be positive for at least one respiratory virus. The virus detection rate for AURTIs and CAP was 23.3% (14/60) and 24.0 % (30/125), respectively. The most prevalent viruses detected were IFVs (13.5%, 25/185), PIVs (3.24%, 6/185) and HRVs (2.70%, 5/185). In the Influenza Virus, the highest positive detection rate is 21.4%（6/28）in the group >60 years old, while 11.0%( 14/127) in the group <40 years old and 13.3% (4/30) (P<0.05). Conclusion: In one-year study, IFVs were the dominant pathogens both in acute upper respiratory tract infections and community-acquired pneumonia, followed by PIVs and HRVs. The patients in the group >60 years old had a higher rate of influenza infection

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
