BACKGROUND AND OBJECTIVE: Pulmonary infiltrates are common in immunosuppressed patients. Bronchoscopy with bronchoalveolar lavage (BAL) is often used to evaluate their aetiology. However, it may not always be easily performed. Thus, alternative diagnostic strategies may be needed. There is limited data on the correlation of nasopharyngeal (NP) respiratory viral panel (RVP)-PCR testing compared with BAL. We aimed to identify the predictive value of NP RVP-PCR samples compared with samples obtained from BAL in immunosuppressed patients with pulmonary infiltrates...

Background: Most acute respiratory infections (ARIs) in children are due to viral etiology; however, over-prescribing of antibiotics for ARIs is common. The aim of this investigation was to identify antibiotic prescribing prevalence for children with ARIs and to identify predictors of broad-spectrum antibiotic prescribing. Methods: This was a prospective cross sectional study in a sample of ambulatory care settings in Jordan. Children (<18 years) presenting with ARIs were assessed in terms of patient's demographics, antibiotic prescription and clinical diagnosis...

A large challenge experiment using North American porcine reproductive and respiratory virus (PRRSV-2) provided new insights into the pathophysiology of reproductive PRRS. Deep phenotyping of dams and fetuses identified maternal and fetal predictors of PRRS severity and resilience. PRRSV infection resulted in dramatic decreases in all leukocyte subsets by 2days post inoculation. Apoptosis in the interface region was positively related to endometrial vasculitis, viral load in endometrium and fetal thymus, and odds of meconium staining...

OBJECTIVES: Viral-lower respiratory tract disease is common in young children worldwide and is associated with high morbidity. Acute respiratory failure due to viral-lower respiratory tract disease necessitates PICU admission for mechanical ventilation. In critically ill patients in PICU settings, early fluid overload is common and associated with adverse outcomes such as prolonged mechanical ventilation and increased mortality. It is unclear, however, if this also applies to young children with viral-lower respiratory tract disease induced acute respiratory failure...

OBJECTIVES: Acute respiratory infections and fever among children are highly prevalent in primary care. It is challenging to distinguish between viral and bacterial infections. Norway has a relatively low prescription rate of antibiotics, but it is still regarded as too high as the antimicrobial resistance is increasing. The aim of the study was to identify predictors for prescribing antibiotics or referral to hospital among children. DESIGN: Secondary analysis of a randomised controlled study...

Asthma is recognized as a complex disease resulting from interactions between multiple genetic and environmental factors. Accumulating evidence suggests that respiratory viral infections in early life constitute a major environmental risk factor for the development of childhood asthma. Respiratory viral infections have also been recognized as the most common cause of asthma exacerbation. The advent of molecular diagnostics to detect respiratory viruses has provided new insights into the role of human rhinovirus (HRV) infections in the pathogenesis of asthma...

We compared the rates of fever in adult subjects with laboratory-confirmed influenza and other respiratory viruses and examined the factors that predict fever in adults. Symptom data on 158 healthcare workers (HCWs) with a laboratory-confirmed respiratory virus infection were collected using standardized data collection forms from three separate studies. Overall, the rate of fever in confirmed viral respiratory infections in adult HCWs was 23·4% (37/158). Rates varied by virus: human rhinovirus (25·3%, 19/75), influenza A virus (30%, 3/10), coronavirus (28·6%, 2/7), human metapneumovirus (28·6%, 2/7), respiratory syncytial virus (14·3%, 4/28) and parainfluenza virus (8·3%, 1/12)...

To determine utility of procalcitonin (PCT) for the prediction of bacterial infection in critically ill children, we analysed the relationship between serum PCT, cultures and other laboratory markers of bacterial sepsis or viral infection in a tertiary paediatric intensive care unit (PICU). The outcome measures were levels of PCT in proven bacteraemia, pneumonia and viral respiratory infection; and comparison of PCT to immature to total neutrophil ratio (ITR) in prediction of bacteraemia. In 420 children with suspected sepsis, 1,226 serum PCT levels were analysed...

Since their discovery in patients with autosomal dominant (AD) chronic mucocutaneous candidiasis (CMC) in 2011, heterozygous STAT1 gain-of-function (GOF) mutations have increasingly been identified worldwide. The clinical spectrum associated with them needed to be delineated. We enrolled 274 patients from 167 kindreds originating from 40 countries from 5 continents. Demographic data, clinical features, immunological parameters, treatment, and outcome were recorded. The median age of the 274 patients was 22 years (range, 1-71 years); 98% of them had CMC, with a median age at onset of 1 year (range, 0-24 years)...
