Chronic as well as recurrent respiratory disorders are major concern in childhood pediatric practice as we commonly come across such cases in day to day pediatric practice. Recurrent respiratory infections are attributed to immaturity of the immune system, functional, structural limitations, dependency on others, unawareness of hygienic importance and nutritional issues related to weaning etc. Excess intake of sweetish substances, growth potential and school environment also contribute for the same. Mean time the congenital abnormalities of the respiratory and cardiovascular system; also, significantly contribute the recurrent respiratory tract infections. Ayurveda explains the stage of Bala or the childhood as stage of immaturity in structural, functional, emotional, and linguistic and behavior and sexual facets with predominance of the Kapha Dosha. Certain of the Respiratory problems in children are also aggravated by the habit of withholding the natural urges as maximum protective reflexes in the upper part of the body pertaining to respiratory system and helps to prevent the portal of entry for maximum infections. Protective reflexes like sneezing, coughing, hiccup, Shrama shwasa, yawning, lacrimation etc., are in true sense keep away the respiratory tract infections. Classics of Ayurveda explain the treatment Kasa in detail and by keeping classical explanation narrated in Kasa Chikitsa of different Samhita. However, classics explains that Pratishyaya when not treated leads to Kasa and Kasa further leads to Rajayakshama. Such incidences are quite common in children as there is immaturity of immune barriers in the growing stage of the child. Hence treatment should contain immune enhancing drugs or other modes of enhancing the immunity which helps to prevent such recurrent infections.

Recurrent infections constitute a major challenge to primary care physicians. Primary immunodeficiency or other alterations of the host defense system are extremely rare. In the case of recurrent respiratory infections, particularly of the lungs, a diagnosis will result much more often from ordering a sweat chloride test than a serum immunoglobulin level. RECURRENT RESPIRATORY INFECTIONS The major reason for referral to our clinic for investigation of the immune system is a complaint of too many upper respiratory tract infections. Each respiratory infection in a young child means loss of sleep for child and parents, expenditure of time at the physician's office, and possible loss of income in addition to the expense of medication and office visits. The child is often irritable and his or her misery clouds the home atmosphere. With repeated episodes of this sort each year, it is small wonder that parents want relief. The average number of upper respiratory tract infections experienced by healthy children is approximately 9 to 10 per year. At least 100 viruses can cause the common cold. Accordingly, even when a child has a normal immune system establishing immunity to each virus or virus subtype, it can take many years for a broad enough immunity to develop to diminish the frequency of infection due to newly encountered respiratory viruses.

Tract Infections

Bacterial lysates stimulate the general immunity of the body in a non-specific way. They act on non-specific defense mechanisms, leading to an increase in type A antibody in mucous membranes, phagocytic activity and INF-ƴ production. They can also stimulate the production of specific antibodies against the bacterial antigens that make up the preparation. The oral immunomodulatory preparations with the best documented clinical efficacy available on the Polish market are Ismigen, Broncho-Vaxom, Ribomunyl and Luivac. They are all lysates of bacterial strains that most often cause respiratory tract infections. In many clinical trials, oral bacterial lysates have been shown to minimize the risk of recurrent respiratory infections in children and adults and reduce the need for antibiotics.

ABSTRACT The distinction between bacterial and viral causes of infections of the respiratory tract is a major but important clinical challenge. We investigated the diagnostic performance of human neutrophil lipocalin (HNL) in respiratory tract infections compared to those of C-reactive protein (CRP) and procalcitonin (PCT). Patients were recruited from the emergency department and from a primary care unit (n = 162). The clinical diagnosis with regard to bacterial or viral cause of infection was complemented with objective microbiological/serological testing. HNL was measured in whole blood after preactivation with the neutrophil activator formyl-methionine-leucine-phenylalanine (fMLP) (B-HNL), and CRP and PCT were measured in plasma. Head-to-head comparisons of the three biomarkers showed that B-HNL was a superior diagnostic means to distinguish between causes of infections, with areas under the concentration-time curve (AUCs) of receiver operating characteristic (ROC) analysis for HNL of 0.91 (95% confidence interval [CI], 0.83 to 0.96) and 0.92 (95% CI, 0.82 to 0.97) for all respiratory infections and for upper respiratory infections, respectively, compared to 0.72 (95% CI, 0.63 to 0.80) and 0.68 (95% CI, 0.56 to 0.79) for CRP, respectively (P = 0.001). In relation to major clinical symptoms of respiratory tract infections (cough, sore throat, stuffy nose, and signs of sinusitis), AUCs varied between 0.88 and 0.93 in those patients with likely etiology (i.e., etiology is likely determined) of infection, compared to 0.63 and 0.71 for CRP, respectively, and nonsignificant AUCs for PCT. The diagnostic performance of B-HNL is superior to that of plasma CRP (P-CRP) and plasma PCT (P-PCT) in respiratory tract infections, and the activity specifically reflects bacterial challenge in the body. The rapid and accurate analysis of HNL by point-of-care technologies should be a major advancement in the diagnosis and management of respiratory infections with respect to antibiotic treatment.

AbstractTo describle how respiratory tract infections (RTIs) that occurred in children with allergic asthma (AA) on allergen immunotherapy (AIT) during an influenza season. Data including clinical symptoms and treatment history of children (those with AA on AIT and their siblings under 14 years old), who suffered from RTIs during an influenza season (Dec 1st, 2019–Dec 31st, 2019), were collected (by face to face interview and medical records) and analyzed. Children on AIT were divided into 2 groups: stage 1 (dose increasing stage) and stage 2 (dose maintenance stage). Their siblings were enrolled as control. During the study period, 49 children with AA on AIT (33 patients in stage 1 and 16 patients in stage 2) as well as 49 children without AA ( their siblings ) were included. There were no significant differences in occurrences of RTIs among the three groups (p > 0.05). Compared with children in the other two groups, patients with RTIs in stage 2 had less duration of coughing and needed less medicine. Children on AIT with maintenance doses had fewer symptoms and recovered quickly when they were attacked by RTIs, which suggested that AIT with dose maintenance may enhance disease resistance of the body.

Abstract Background Acute respiratory infections (ARIs) are among the leading causes of hospitalization in children. Understanding the local dominant viral etiologies is important to inform infection control practices and clinical management. This study aimed to investigate the viral etiology and epidemiology of respiratory infections among pediatric inpatients in Macao. Methods A retrospective study using electronic health records between 2014 and 2017 at Kiang Wu Hospital was performed. Nasopharyngeal swab specimens were obtained from hospitalized children aged 13 years or younger with respiratory tract diseases. xMAP multiplex assays were employed to detect respiratory agents including 10 respiratory viruses. Data were analyzed to describe the frequency and seasonality. Results Of the 4880 children enrolled in the study, 3767 (77.1%) were positive for at least one of the 13 viral pathogens tested, of which 2707 (55.5%) being male and 2635 (70.0%) under 2 years old. Among the positive results, there were 3091 (82.0%) single infections and 676 (18.0%) multiple infections. The predominant viruses included human rhinovirus/enterovirus (HRV/EV 27.4%), adenovirus (ADV, 15.8%), respiratory syncytial virus B (RSVB, 7.8%) and respiratory syncytial virus A (RSVA, 7.8%). The detection of viral infection was the most prevalent in autumn (960/1176, 81.6%), followed by spring (1095/1406, 77.9%), winter (768/992, 77.4%), and summer (944/1306, 72.3%), with HRV/EV and ADV being most commonly detected throughout the 4 years of study period. The detection rate of viral infection was highest among ARI patients presented with croup (123/141, 87.2%), followed by lower respiratory tract infection (1924/2356, 81.7%) and upper respiratory tract infection (1720/2383, 72.2%). FluA, FluB and ADV were positive factors for upper respiratory tract infections. On the other hand, infection with RSVA, RSVB, PIV3, PIV4, HMPV, and EV/RHV were positively associated with lower respiratory tract infections; and PIV1, PIV2, and PIV3 were positively associated with croup. Conclusions This is the first study in Macao to determine the viral etiology and epidemiology of pediatric patients hospitalized for ARIs. The study findings can contribute to the awareness of pathogen, appropriate preventative measure, accurate diagnosis, and proper clinical management of respiratory viral infections among children in Macao.

Rationale The relevance of ventilator-associated respiratory tract infections in severe injury patients (SIP) is associated with both features of causative pathogens and the initial severity of the state of patients. Among causative pathogens nosocomial flora is dominant. Purpose - to perform an analysis of the microbiological monitoring of ventilator-associated respiratory tract infections in SIP. The analysis was based on the results of a prospective epidemiological, clinical, and instrumental study of 100 SIP with ventilator-associated respiratory tract infections, stayed in the surgical intensive care unit. The proportion of ventilator-associated respiratory infections in the structure of nosocomial infections in these patients is between 90 - 95%, at that there was revealed the prevalence of nosocomial pneumonia (61%). Ventilator-associated respiratory tract infection most commonly occurs during the first 10 days of mechanical ventilation. The prevailing flora was represented by Gram negative Acinetobacter baumamnnii (40.3 ± 2.1%) and Pseudomonas aeruginosa (38.4% ± 3.2%). Isolated microorganisms possessed multiple antibiotic resistance, with the greatest extent to aminoglycosides - 69.5%, fluoroquinolones - 40.3%, penicillin - 37.6%; cephalosporins (third generation) - 33.8%. There is noted marked preponderance of microbial associations compared with monocultures 57.1 ± 5.3%.

Abstract Background There is a lack of studies comparing PCT, CRP and WBC levels in the differential diagnosis of acute bacterial, viral, and mycoplasmal respiratory tract infections. It is necessary to explore the correlation between above markers and different types of ARTI. Methods 108 children with confirmed bacterial infection were regarded as group A, 116 children with virus infection were regarded as group B, and 122 children with mycoplasmal infection were regarded as group C. The levels of PCT, CRP and WBC of the three groups were detected and compared. Results The levels of PCT, CRP and WBC in group A were significantly higher than those in groups B and C (p < 0.05). The positive rate of combined detection of PCT, CRP and WBC was significant higher than that of single detection. There was no significant difference in PCT, CRP and WBC levels between the group of G+ bacterial infection and G− bacterial infection (p > 0.05). ROC curve results showed that the AUC of PCT, CRP and WBC for the diagnosis of bacterial respiratory infections were 0.65, 0.55, and 0.58, respectively. Conclusions PCT, CRP and WBC can be combined as effective indicators for the identification of acute bacterial or no-bacterial infections in children. The levels of PCT and CRP have higher differential diagnostic value than that of WBC in infection, and the combined examination of the three is more valuable in clinic.

Background: COVID-19 outbreak lead to nationwide lockdown on the March 16th, 2020 in Turkey. We aimed to quantitively determine the change in frequency of upper and lower respiratory tract infections and asthma in pediatric population associated with COVID-19. Methods: The electronic medical record data of pediatric population admitted to the emergency department (ED), outpatient and inpatient clinics and pediatric intensive care unit (PICU) were analyzed with the diagnosis of Influenza, upper and lower respiratory tract infections (URTI, LRTI) acute bronchiolitis and asthma. The data of the first year of the pandemic was compared with the previous year. Results: In total 112496 admissions were made between April 1, 2019 and March 31, 2021 in our hospital. A decline was observed in ED admissions (-73%) and outpatient clinic (-70%) visits, hospitalizations (-41.5%) and PICU admissions (-42%). The admissions with the diagnosis of Influenza and URTI had a decline from 4.26% to 0.37% (p=0.0001), and from 81.54% to 75.62% (p=0.0001), respectively. An increase was observed in the LRTI, acute bronchiolitis and asthma (from 8.22% to 10.01% (p=0.0001), from 2.76% to 3.07% (p=0.027) and from 5.96% to 14% (p=0.0001), respectively). Conclusions: A dramatic decrease was observed in the number of admissions to ED and inpatient clinics and outpatient clinic visits and PICU admissions, and, when the rates of admissions were compared, the general rate of admissions to ED showed a decrease while inpatient, outpatient clinics and PICU admissions demonstrated an increase during the pandemic.

Upper respiratory tract infections are the most common maladies experienced by humankind.1 The majority are caused by respiratory viruses. A Dutch case-controlled study of primary care patients with acute respiratory tract infections found that viruses accounted for 58% of cases; rhinovirus was the most common (24%), followed by influenza virus type A (11%) and corona­viruses (7%). Group A streptococcus (GAS) was responsible for 11%, and 3% of patients had mixed infections. Potential pathogens were detected in 30% of control patients who were free of acute respiratory symptoms; rhinovirus was the most common.2 Given the increasing problem of antibiotic resistance and the increasing awareness of the importance of a healthy microbiome, antibiotic use for upper respiratory infections should be reserved for those patients with clear indications for treatment. A recent study of adult outpatient visits in the United States found that respiratory complaints accounted for 150 antibiotic prescriptions per 1,000 population annually, yet the expected “appropriate” rate would be 45.3 In other words, most antibiotic prescriptions for these complaints are unnecessary. Similarly, a study in the United Kingdom found that general practitioners prescribed antibiotics to about half of all patients presenting with an upper respiratory infection, even though most of these infections are viral.4 This review contains 5 figures, 16 tables, and 82 references.
