Background: Babesia infections in dogs can result in a wide range of clinical and laboratory presentations, including coagulopathy. Expression of intercellular adhesion molecule-1 (ICAM-1) and von Willebrand factor (vWF) in dogs with babesiosis is unknown.Objectives: Whether inflammation in babesiosis triggers activation of ICAM-1 and the coagulation system. Animals: Twelve and 10 dogs with naturally occurring babesiosis before and after antiparasitic treatment, respectively, were compared with 10 healthy dogs.Methods: In this prospective study, diagnosis was made by blood smear examination and confirmed by PCR. C-reactive protein (CRP), soluble intercellular adhesion molecule 1 (sICAM-1), and von Willebrand factor (vWF) levels were measured by a canine ELISA kit, fibrinogen (FIB) and factor VIII activity levels were measured by coagulometric methods, and blood cell counts (WBC, RBC, PLT) were determined with an automatic analyzer.Results: Compared to healthy dogs, the CRP, sICAM-1, and FIB concentrations were significantly increased before therapy and remained high for 3 days after therapy in dogs with babesiosis. vWF activity was significantly decreased in dogs with babesiosis before treatment. FVIII activity did not differ between dogs with babesiosis and healthy dogs. WBC; RBC and PLT were significantly lower before treatment and normalized by 3 days after treatment.Conclusion and Clinical Importance: A proinflammatory condition in babesiosis appears to influence endothelial dysfunction and hemostatic activity. Although clearly beneficial for the parasite, sequestered blood cells can obstruct blood flow in small vessels, promote an inflammatory state, and could increase the severity of babesiosis.

Cigarette smoke induces activation of PMN in healthy controls. However, chronically activated PMN in COPD patients could not be further stimulated by in vitro exposure to CSE. Constantly raised amount of MMP-9 released into the tissues may be involved in the degradation of extracellular matrix in the lungs as seen in COPD patients.

Dysregulation of inflammatory mediators is characteristic for chronic inflammation in allergy. The aim was to determine the values of serum IL-17 and IL-5 in ragweed-sensitized children. The study included children analyzed during the ragweed pollen season compared to children analyzed out of season. Serum total IgE, specific IgE, and eosinophil cationic protein (ECP) were determined by fluoroimmunoassay while the concentrations of IL-5 and IL-17 were determined by flow cytometry. Patients evaluated during the pollen season, have higher values of total and specific IgE, eosinophil and neutrophil count than patients studied outside the pollen season. There was no statistically significant seasonal and out of season differences for the concentration of IL-17, IL-5, and ECP. Natural exposure to ragweed pollen allergen was not crucial for the induction of increased IL-17 and IL-5 synthesis, and factors other than allergen exposure should be investigated, especially in longitudinal studies of patients.
