[Clinical and some biochemical features of rhinosinusitis of different etiology]

Identified pathogens, and studied the features of the clinical picture, the level of antioxidant activity, the number of TBA-active products, cytokines, chaperones proteins and antibodies against them in the serum of patients with fungal, viral, bacterial rhinosinusitis (RS) were studied. Most RS of viral nature are caused by rhinoviruses, in turn, the causative agent of bacterial RS, most often acts as a polyflora (S. epidermidis, S. aureus, Pseudomonas aeruginosa). In the group of fungal RS prevailed A. fumigatus. It is noted that a more severe clinical picture in patients bacterial RS; it was manifested by a prolonged course, more pronounced nasal congestion, smell impairment and frequent relapses of the disease. High levels of LPO and a decrease in serum antioxidant activity were established for all studied infectious RS with a maximum imbalance in the LPO-AOP system in fungal forms; shift of the cytokine profile towards pro-inflammatory factors (IL-1b, IL-2, IL-8, IL-6) was registered in bacterial and viral RS and towards the values of anti-inflammatory IL-4 - in fungal RS. The increased amount of chaperone proteins was seen in bacterial RS; high concentration of antibodies against them was noted in fungal and viral RS.
