Acute focal bacterial nephritis (AFBN) is a localized, interstitial bacterial infection of the renal parenchyma. In this study, we measured the serum levels of several cytokines in patients with AFBN. A total of 11 children were enrolled in the study and classified into two groups of patients: an AFBN group and a control group. There was no significant difference in the serum levels of interleukin (IL)-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17, granulocyte-colony stimulating factor, or tumor necrosis factor-α among the patients in the two groups. However, the serum levels of interferon-γ among the patients in the AFBN group were significantly higher than those among the patients in the control group. The current results suggest that the bacterial kidney infection in the AFBN group is localized and that interferon-γ may be produced locally in response to the infection.
The authors report a Japanese boy with severe pandemic influenza A(H1N1) 2009-associated pneumonia and deteriorating oxygenation. He dramatically recovered after the use of Airway Pressure Release Ventilation (APRV) mode. There was no improvement by using any conventional ventilation, however, APRV immediately led to an improvement of his clinical symptoms and laboratory findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
