Objective To investigate the relationship of the clinical appearance, histological characteristics, bacterial culturing, and messenger RNA (mRNA) expression of RANTES, interleukin 6, and interleukin 12, as well as the occurrence of endothelial adhesion molecules, in inflammatory diseased maxillary sinus mucosa in critically ill patients.
Design Prospective case series.
Setting General intensive care unit and neurosurgical intensive care unit of a tertiary care hospital.
Subjects Seven critically ill patients, nasotracheally intubated or tracheotomized, who received ventilator treatment for more than 7 days and treatment with antibiotics.
Interventions Bilateral biopsy specimens of antral mucosa were obtained at sinoscopy. Reverse transcriptase—polymerase chain reaction was used to detect the cytokine mRNAs in situ on paraformaldehyde-fixed tissue, and intercellular adhesion molecule 1, vascular cell adhesion molecule 1, E-selectin, and P-selectin were analyzed by immunochemistry on frozen sections. Sampling of secretion and tissue from the antra was performed for bacterial culturing.
Results Macroscopic and histological appearance varied and showed moderate to pronounced inflammation in 6 antra. All 4 bacterially infected antra showed mRNA RANTES (P=.005). No correlation was found for interleukin 6 and interleukin 12. Up-regulation of P-selectin in all cases and sparse expression of vascular cell adhesion molecule 1 indicate that the inflammation is chronic but nonallergic in type.
Conclusion We find an indication that RANTES is more prevalent in bacterial sinusitis.
