Relationship Between Upper Respiratory Tract Influenza Test Result and Clinical Outcomes Among Critically Ill Influenza Patients
نویسندگان
چکیده
Among critically ill patients with lower respiratory tract (LRT)-confirmed influenza, we retrospectively observed worse 28-day clinical outcomes in upper respiratory tract (URT)-negative versus URT-positive subjects. This finding may reflect disease progression and highlights the need for influenza testing of both URT and LRT specimens to improve diagnostic yield and possibly inform prognosis.

Background and Aim: Respiratory tract infections are one of the important causes of death among children in developing countries. Although their frequency is similar in both developed and developing countries, mortality due to them is 10-50 times higher in developing countries. Viruses are common causes of these infections among children and Influenza, adeno and respiratory syncytial virus ...

BACKGROUND Pneumonia patients with wheezing due to influenza A(H1N1)pdm09 were frequently treated with systemic corticosteroids in Japan although systemic corticosteroid for critically ill patients with pneumonia caused by influenza A(H1N1)pdm09 has been controversial. Applicability of systemic corticosteroid treatment needs to be evaluated. METHODS/PRINCIPAL FINDINGS We retrospectively revie...
