1/44. Surfactant replacement therapy in RSV-induced acute respiratory distress syndrome (ARDS).Acute respiratory distress syndrome (ARDS) associated with severe respiratory syncytial virus infection is rare. We report a 5-month-old Indian girl who was admitted to our intensive care ward with severe respiratory failure who fulfilled the criteria for ARDS using both Murray's lung injury Score of > 2.5 and the American-European consensus Conference definition for ARDS. She developed diffuse bilateral alveolar infiltrates, severe hypoxaemia (PaO2/FiO2 < 100) and required high PEEP (> 15 cm H2O) 24 hours after admission. RSV was isolated from her nasopharyngeal secretion. She also had clinical features suggestive of a primary immunodeficiency and had laboratory evidence of combined T and B cell defect. There was unsustained clinical improvement with a dose of surfactant administered at 36 hours of PICU stay, and she continued to deteriorate and succumbed after 19 days in the PICU.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/44. Pulmonary failure after Norwood procedure: indication for extracorporeal membrane oxygenation? A case report.Today some authors consider univentricular repair a contraindication for postoperative cardiac extracorporeal membrane oxygenation (ECMO). The question is whether or not ECMO is indicated as pulmonary support in case of an overwhelming pulmonary infection during the postoperative course after a Norwood procedure. During the prolonged weaning period after a Norwood procedure using a 4 mm aortopulmonary shunt, proven respiratory syncytial virus (RSV) bronchiolitis occurred at the time of expected weaning from artificial ventilation. Venovenous ECMO was able to improve oxygenation, but when pulmonary opacification failed to resolve, ECMO was terminated after 12 days.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
3/44. bronchiectasis and bronchiolitis obliterans post respiratory syncytial virus infection: think again.Respiratory syncytial virus (RSV) lower respiratory tract infections are common, yet long-term sequelae in previously healthy infants and children are rarely reported. We report a child who developed bronchiectasis and bronchiolitis obliterans following an RSV lower respiratory tract infection but in whom adenovirus was detected on stored serum. Co-infection with adenovirus is the likely cause for the bronchiectasis and bronchiolitis obliterans.- - - - - - - - - - ranking = 7keywords = infection (Clic here for more details about this article) |
4/44. Respiratory syncytial virus infection in patients with phagocyte defects.patients with phagocyte defects frequently develop bacterial or fungal pneumonias, but they are not considered to be at increased risk for viral infections. We describe 3 patients with known phagocyte immunodeficiencies who developed lower respiratory tract infections (LRTI) caused by respiratory syncytial virus (RSV). All 3 patients had dense pneumonias as indicated by computed tomography scan of the lungs and RSV was recovered. We conclude that RSV can present as a dense pneumonia in patients with phagocyte defects. Along with common pathogens causing LRTI, RSV should be considered in the differential diagnosis. Viral cultures as well as rapid antigen detection assays for respiratory viruses should be included in the evaluation of LRTI in patients with phagocyte defects. respiratory syncytial virus, phagocyte, immunodeficiency, pneumonia.- - - - - - - - - - ranking = 6keywords = infection (Clic here for more details about this article) |
5/44. Donor lymphocyte infusion for treatment of life-threatening respiratory syncytial virus infection following bone marrow transplantation.We describe two patients who developed respiratory syncytial virus (RSV) pneumonia after BMT. One died of RSV pneumonia after three courses of steroid pulse therapy. Surprisingly, RSV antigen was identified in the bronchoalveolar lavage fluid (BALF) obtained post mortem. Steroid pulse therapy might have suppressed anti-RSV immunity, leading to persistent RSV infection for more than 1 month. The other patient received donor lymphocyte infusions (DLI) for relapsed plasma cell leukemia, while having active RSV pneumonia. His respiratory condition improved after DLI, and RSV antigen disappeared in BALF and nasal swabs. DLI might be effective in cases of life-threatening RSV pneumonia.- - - - - - - - - - ranking = 5keywords = infection (Clic here for more details about this article) |
6/44. Encephalopathy associated with respiratory syncytial virus bronchiolitis.Respiratory syncytial virus is an extremely common cause of childhood respiratory infections resulting in significant morbidity and mortality. Although apnea is a well-known complication in young infants with respiratory syncytial virus bronchiolitis, the encephalopathy associated with this infection is not well recognized. Our study reveals an incidence of encephalopathy of 1.8% in a total of 487 patients with respiratory syncytial virus bronchiolitis studied over a period of almost 4 years. seizures were the presenting complication. Based on our study of a cohort of children with respiratory syncytial virus bronchiolitis, we believe that neurologic complications, although relatively uncommon, represent a significant component of this common childhood illness. Furthermore, respiratory syncytial virus has been shown to release several mediators that could directly or indirectly be neurotoxic and induce an encephalopathy associated with the respiratory illness.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
7/44. Respiratory syncytial virus infection in the late bone marrow transplant period: report of three cases and review.Respiratory syncytial virus (RSV) infection is an important cause of respiratory mortality in immunosuppressed patients, including bone marrow transplant (BMT) recipients. The presence of lower respiratory tract infection and infection in the pre-engraftment phase of BMT is believed to confer a poor prognosis. Three patients who underwent allogeneic BMT at our institution developed RSV pneumonia over 1 year post BMT, with the underlying disease in remission. All three were hypoxic with extensive pulmonary disease at presentation. Treatment consisted of aerosolized ribavirin and intravenous immune globulin with successful clearing of viral shedding and excellent clinical outcomes. RSV infection is probably less severe in the late post-BMT period, but needs to be considered early in the differential diagnosis of pulmonary infiltrates in this patient population.- - - - - - - - - - ranking = 8keywords = infection (Clic here for more details about this article) |
8/44. Virus-induced asthma attacks.Viral respiratory tract infections are a common cause of asthma attacks. Study of this phenomenon has revealed multiple mechanisms and contributed to understanding of the increase in airway inflammation and bronchoconstriction observed in this context. Changes in the neural control of the airways contribute to bronchoconstriction, which is reflected in an increased efficacy of anticholinergic medications during acute asthma attacks. The ability to prevent or treat viral respiratory tract infections is currently limited. However, as more effective antiviral treatments and vaccines become available, such therapies are likely to be effective in patients with asthma. Clinical management of this problem is illustrated in this article by the case of a 40-year-old woman with history of mild asthma who was admitted to an intensive care unit with severe bronchospasm and an upper respiratory tract infection.- - - - - - - - - - ranking = 3keywords = infection (Clic here for more details about this article) |
9/44. Severe respiratory syncytial virus pneumonia associated with primary Epstein-Barr virus infection.This is a case report of a child with severe respiratory syncytial virus (RSV) pneumonia and concurrent infection with Epstein-Barr virus. We hypothesize that immunosuppression due to EBV may have contributed to the severity of his RSV infection. The diagnosis of RSV infection was facilitated by bronchoalveolar lavage.- - - - - - - - - - ranking = 7keywords = infection (Clic here for more details about this article) |
10/44. Simultaneous viral infection and childhood bronchiolitis obliterans.Lower respiratory tract infections by respiratory syncytial virus (RSV) are frequent in childhood. association of RSV with bronchiolitis obliterans has rarely been established. We report a 13-month-old child with bronchiolitis obliterans following co-infection by RSV and adenovirus, and suggest that complicated evolution of an acute bronchiolitis case can indicate an association of pathogens.- - - - - - - - - - ranking = 6keywords = infection (Clic here for more details about this article) |
