This study analysed the role of several risk factors for hospitalization due to community-acquired, respiratory syncytial virus (RSV) infection. The risk factors detected in infants hospitalized for RSV infection in the first 24 months of life were compared with those in the general infant population in our region. There were 361 episodes of hospitalization in 357 infants. Eighty per cent of the infants did not present underlying conditions for severe RSV infection and only 10 (3%) were candidates for palivizumab prophylaxis. In multivariate analysis, birthweight of <2500 g was independently associated with hospitalization for RSV infection and was the most commonly detected medical risk factor. Other risk factors were maternal age at delivery <25 years, birth in the second half of the year, prematurity, suburban residence and congenital heart disease. In conclusion, together with well-known risk factors, we found that low birthweight was an independent factor for severe RSV infection.

Systemic-pulmonary collateral arteries are known to develop in children with congenital heart disease, chronic pulmonary infection, and prematurity. At present, these abnormal connections between the systemic and the pulmonary systems are thought to develop from the vascular plexus, which normally gives rise to the pulmonary and bronchial vasculature. The objective of this study was to review our patients with systemic-pulmonary collateral arteries and evaluate possible risk factors. The records of patients with systemic-pulmonary collateral arteries seen at our hospital over a 4-year period were retrospectively reviewed. They were grouped into one of the following five categories: premature, heart disease, pulmonary disease, healthy, and others. Age, gender, weight, and the results of echocardiography were recorded, as was the condition on follow-up. We reviewed the records of 284 patients: 130 premature, 13 heart disease, 30 pulmonary disease, 92 healthy, and 19 others. Over the same period, 3314 healthy 1-month-old infants had undergone echocardiography for health screening. Among the 92 healthy children with systemic-pulmonary collateral arteries, 52 were diagnosed at the health-screening exam. Therefore, we estimate the incidence of unsuspected systemic-pulmonary collateral arteries in healthy 1-month-old infants to be 1.57% (52/3314). We conclude that systemic-pulmonary collateral arteries may be present normally after birth and then gradually disappear. However, if there are certain predisposing factors, they may persist in order to augment pulmonary flow.

Premature birth, chronic lung disease of prematurity (CLD), congenital heart disease and immunodeficiency predispose to a higher morbidity and mortality in respiratory syncytial virus (RSV) infection. This study describes the preterms hospitalised with RSV infection from the prospective German DSM RSV Paed database. The DMS RSV Paed database was designed for the prospective multicentre documentation and analysis of clinically relevant aspects of the management of inpatients with RSV infection. This study covers six consecutive RSV seasons (1999-2005); the surveillance took place in 14 paediatric hospitals in Germany. Of the 1,568 prospectively documented RSV infections, 26% (n=406) were observed in preterms [vs. 1,162 children born at term (74%)] and 3% (n=50) had CLD, of which 49 had received treatment in the last 6 months ('CLDplus'). A significantly higher proportion in the preterm group had congenital heart disease, nosocomial infection, and neuromuscular impairment. There were significantly more children older than 24 months in the preterm group. The attributable mortality was 0.2% (n=2) in children born at term vs. 1.2% (n=5) in the preterm group (p=0.015) [preterm plus CLD 8.0% (n=4 of 50); McIntosh grade 1, 8.6% (n=3 of 35) and McIntosh Grade 4, 15% (n=3 of 20)]. Eight patients were categorized as 'palivizumab failures'. In the multivariate analysis, premature birth, CLD(plus), and nosocomial infection were significantly and independently associated with the combined outcome 'complicated course of disease'. In conclusion, this is the first prospective multicentre study from Germany that confirms the increased risk for severe RSV disease in preterms, in particular in those with CLD treated in the last 6 months before the onset of the infection. From the perspective of our results, the statements of the German Society of Paediatric Infectious Diseases considering the use of passive immunisation (2003) seem reasonable.

Respiratory syncytial virus (RSV) immune globulin is a purified human hyperimmune globulin that provides passive immunity against complicated RSV disease in select groups of infants and young children. According to microneutralisation assay results, its RSV-neutralising antibody concentration was significantly greater than that of nonspecific immune globulin, thereby suggesting the potential for more reliable protection against RSV infection. In 2 randomised double-blind trials, prophylaxis with RSV immune globulin significantly reduced (vs no immune globulin) the incidence and severity of RSV disease in infants and young children with bronchopulmonary dysplasia, prematurity or bronchopulmonary dysplasia due to prematurity, or congenital heart disease (in 1 study). Treatment with RSV immune globulin did not significantly reduce the duration of hospitalisation and intensive care in children hospitalised with RSV infection in 2 randomised double-blind trials; however, a trend towards a significant treatment benefit was apparent in children with severe disease in 1 of these studies.

Neonatal hypoxic-ischemic encephalopathy, prematurity, sepsis-meningitis, and serious forms of complex congenital heart disease requiring infant heart surgery are just a few examples of disorders that share high mortality and morbidity rates. Newborn heart surgery represents a period of planned and deliberate ischemia-reperfusion injury, which is obliged to occur to cure or palliate complex forms of congenital heart disease. Advances in cardiothoracic surgical and anesthetic techniques, including cardiopulmonary bypass and deep hypothermic circulatory arrest, have substantially decreased mortality, expanding the horizon to address functional neurologic and cardiac outcomes in long-term survivors. Interest in the functional status of survivors now stretches beyond the newborn period to childhood, adolescence, and adulthood.

One thousand five hundred sixty-eight RSV infections were documented prospectively in 1,541 pediatric patients. Of these, 20 (1.3%) had acquired the RSV infection while treated by mechanical ventilation for reasons other than the actual RSV infection (group ventilated mechanically). The clinical characteristics of children who were infected with respiratory syncytial virus (RSV) infection while ventilated mechanically for other reasons are described and compared with a matched control group. Sixty percent of the group ventilated mechanically had at least one additional risk factor for a severe course of infection (prematurity 50%, chronic lung disease 20%, congenital heart disease 35%, immunodeficiency 20%). The median age at diagnosis in the group ventilated mechanically was 4.2 months. The matched pairs analysis (group ventilated mechanically vs. control group) revealed a higher proportion of patients with hypoxemia and apnoea in the group ventilated mechanically; more patients in the control group showed symptoms of airway obstruction (wheezing). At least one chest radiography was performed in 95% of the patients (n = 19) in the group ventilated mechanically versus 45% (n = 9) in the control group (P = 0.001). The frequency of pneumonia was 40% in the group ventilated mechanically and 20% in the control group. Despite existing consensus recommendations, only two patients (10%) of the group ventilated mechanically had received palivizumab previously. Significantly more patients in the group ventilated mechanically received antibiotic treatment (85% vs. 45%, P = 0.008), and attributable mortality was higher in the group ventilated mechanically (15% [n = 3] vs. 0% in the control group, P = 0.231). Children treated by long term mechanical ventilation may acquire RSV infection by transmission by droplets or caregivers and face an increased risk of a severe course of RSV infection. The low rate of immunoprophylaxis in this particular risk group should be improved.

Intestinal failure (IF) is a complex, chronic illness, of increasing importance in the pediatric critical care setting. We can expect an increase in pediatric IF given an increase in the survivors of extreme prematurity and complex congenital heart disease. Overall priorities for management of this condition include surgical and medical strategies to promote intestinal adaptation and to reduce complications, particularly related to malnutrition, liver disease and sepsis. In this review the authors propose that the optimal care for children with IF are multidisciplinary teams abreast of the newest strategies for intestinal rehabilitation. Early listing for intestinal transplantation for children at greatest risk of long-term parenteral nutrition dependency and its life threatening complications is appropriate.

Palivizumab (Synagis) is a monoclonal antibody directed against the respiratory syncytial virus (RSV), for reducing mortality and morbidity in infants at risk of cardio-respiratory impairement due to bronchiolitis: 1. prematurity less than 28 weeks and less than 1 year of age; 2. between 28 and 32 weeks plus mechanical ventilation and less than 6 months of age; 3. chronic lung deficiency and less than 2 years of age; 4. congenital cardiopathy with either desaturation, pulmonary hypertension or cardiac failure. Another group of infants is those having a severe imnnunodeficiency. These infants are listed in a hospital recognized to have a competence in neonatal intensive care or a cardio-thoracic care program. The specialist in those disciplines prescribe the palivizumab which is delivered by the pharmacy of the competent hospital. The infant receives it by IM route at a dose of 15 mg/kg, monthly between October or November and February or March. Reduction of mortality and morbidity have been observed in the infants at risk. However, this costly pharmacological preventive approach needs to come after other simple preventive measures such as avoiding contact with potential carriers of nasal viruses and passive smoking, for bronchiolitis is not solely due to RSV.

Bronchiolitis is a leading cause of hospitalisation in infancy, with respiratory syncytial virus (RSV) being the most common pathogen. Younger age, especially infants younger than 3 months of age, environmental factors and genetic susceptibility, are associated with increased risk of hospitalisation. Most importantly, conditions such as prematurity, in particular if associated with chronic lung disease, congenital heart disease, lung disease such as cystic fibrosis, neuromuscular disease or impairment, or congenital or acquired immune deficiencies, are associated with increased risk of RSV hospitalisation and severe RSV lung disease. In these high risk populations, a 3- to 10-fold increase in the rate of RSV hospitalisation has been observed, justifying RSV-specific prophylaxis with palivizumab during the first, and in the populations at highest risk, the second RSV season. Studies have demonstrated a significant reduction (approximately 50%) in the rate of RSV hospitalisation in high-risk infants treated with palivizumab during the RSV season.

Palivizumab was licensed in June 1998 by the US Food and Drug Administration for prevention of serious lower respiratory tract disease caused by respiratory syncytial virus (RSV) in pediatric patients who are at increased risk of severe disease. Safety and efficacy have been established for infants born at or before 35 weeks' gestation with or without chronic lung disease of prematurity and for infants and children with hemodynamically significant heart disease. The American Academy of Pediatrics (AAP) published a policy statement on the use of palivizumab in November 1998 (American Academy of Pediatrics, Committee on Infectious Diseases and Committee on Fetus and Newborn. Pediatrics. 1998;102[5]:1211-1216) and revised it in December 2003 (American Academy of Pediatrics, Committee on Infectious Diseases and Committee on Fetus and Newborn. Pediatrics. 2003;112[6 pt 1]:1442-1446), and an AAP technical report on palivizumab was published in 2003 (Meissner HC, Long SS; American Academy of Pediatrics, Committee on Infectious Diseases and Committee on Fetus and Newborn. Pediatrics. 2003;112[6 pt 1]:1447-1452). On the basis of the availability of additional data regarding seasonality of RSV disease as well as the limitations in available data on risk factors for identifying children who are at increased risk of serious RSV lower respiratory tract disease, AAP recommendations for immunoprophylaxis have been updated in an effort to ensure optimal balance of benefit and cost from this expensive intervention. This statement updates and replaces the 2003 AAP statement and the 2006 Red Book and is consistent with the 2009 Red Book recommendations.
