Nasal interleukin-5, immunoglobulin E, eosinophilic cationic protein, and soluble intercellular adhesion molecule-1 in chronic sinusitis, allergic rhinitis, and nasal polyposis

OBJECTIVE: To compare concentrations of interleukin-5 (IL-5), immunoglobulin E (IgE), eosinophilic cationic protein (ECP), and soluble intercellular adhesion molecule-1 (sICAM-1) in nasal secretion and serum of patients with chronic nonallergic sinusitis, allergic rhinitis, and nonallergic nasal polyposis to obtain information about the pathogenesis of these diseases. METHODS: Nasal secretion and serum were analyzed by routine enzyme-linked immunosorbent assay techniques. Nineteen patients with chronic nonallergic sinusitis, 24 patients with seasonal allergic rhinitis, and 18 patients with nonallergic nasal polyposis were included in the study. Eight healthy, nonallergic probands served as control subjects. RESULTS: Significantly elevated concentrations of IL-5 (5-fold, P < .05) and IgE (15-fold, P < .01) were detected in nasal secretion of patients with allergic rhinitis (IL-5, 51.8 +/- 13.2 pg/mL; IgE, 41.9 +/- 20.9 kU/L) or nonallergic nasal polyposis (IL-5, 57.9 +/- 36.9 pg(mL; IgE, 40.5 +/- 20.2 kU/L) compared with controls (IL-5, 10.6 +/- 7.8 pg/mL; IgE, 2.8 +/- 0.5 kU/L) or with patients with chronic nonallergic sinusitis (IL-5, 16.5 +/- 13.2 pg/mL; IgE, 5.4 +/- 3.1 kU/L). There were no significant differences between patients with allergic rhinitis and those with nonallergic nasal polyposis. Concentrations of ECP were significantly elevated (sixfold, P < .01) in patients with allergic rhinitis (297.8 ng/mL +/- 173.1) compared with controls (52.4 +/- 28.0 ng/mL) or patients with chronic nonallergic sinusitis (44.8 +/- 40.1 ng/mL), whereas twofold higher concentrations (not significant) of ECP were observed in patients with nonallergic nasal polyposis (107.1 +/- 26.6 ng/mL). Significantly elevated concentrations of sICAM-1 in nasal secretion (threefold, P < .05) were detected only in patients with chronic nonallergic sinusitis (79.4 +/- 45.6 ng/mL). The elevated sICAM-1 nasal secretion values in this group correlated significantly (P < .05) to the serum values. CONCLUSIONS: Equally elevated concentrations of IL-5 and IgE in patients with allergic rhinitis and nonallergic nasal polyposis implicated similar pathogenic processes in both diseases. Whereas the pathogenesis of allergic rhinitis is IgE-specific, the pathogenesis of nasal polyps is not as clear. IL-5 was suggested to play a pivotal role in tissue eosinophilia, which was confirmed by data in the present study. Elevated concentrations of ECP were suggested to result from tissue eosinophilia--a characteristic of both diseases. Elevated concentrations of sICAM-1 in patients with chronic nonallergic sinusitis pointed to its key role in the recruitment of neutrophils into the inflamed tissue, whereas an important role in eosinophil recruitment was ruled out.     

TNF-α和 IL-8在变应性鼻炎发病中的作用探讨

变应性鼻炎鼻腔灌洗液和血清中嗜酸粒细胞阳离子蛋白和E-选择素的检测

OBJECTIVE: To evaluate the role of eosinophil cationic protein (ECP) and serum soluble E-selectin (sE-selectin) in patients with allergic rhinitis. METHODS: The sE-selectin were detected from 30 allergic patients and 20 normal individuals by enzyme-linked immunosorbent assay (ELISA). The ECP in serum and nasal lavage fluid was assayed with pharmacia CAP system. RESULTS: The level of sE-selectin in patients with allergic rhinitis was(41.846 +/- 12.21) ng/ml, higher than that in control (10.678 +/- 2.458) ng/ml. The level of ECP in serum and nasal lavage fluid from patients with allergic rhinitis was significantly higher than that from normal controls. The level of ECP in nasal lavage fluid was much higher than that in serum. CONCLUSION: ECP and sE-selectin play a role in pathogenesis of allergic rhinitis.     

Effect of garlicin on the serum levels of interleukin 4 and interferon gamma in allergic rhinitis model in rats

OBJECTIVE: To investigate the effect of garlicin on the levels of interferon gamma (INF-gamma) and interleukin 4 (IL-4) in blood of allergic rhinitis rat model. METHODS: Thirty healthy female SD rats were randomly divided into 3 groups: control group, negative control group and experimental group, 10 rats for each group. Ten rats (experimental group) were sensitized and intranasally challenged by ovalbumin, aluminium hydroxide hydrate gel and Bordetella pertussis inactive microorganism suspension adjuvants, as allergic rhinitis models, and then injection of garlicin(0.4 ml) intraperitoneally per day for 10 days. Control group rats were immunized as experimental group, and then injection of physiological saline as equal volume as garlicin. Negative control group rats were investigated using physiological saline. Blood of intrajugular vein of rat was extracted for separated plasma Enzyme liked immunosorbent assay (ELISA) was utilized to detect the serum levels of IL-4 and IFN-gamma. RESULTS: The serum levels (x +/- s) of IL4 were (22.81 +/- 8.79) pg/L, (41.43 +/- 4.93) pg/L, (9.93 +/- 2.07) pg/L, and those of IFN-gamma were (22.32 +/- 11.20) pg/L, (11.35 +/- 2.45) pg/L and (21.69 +/- 5.93) pg/L, respectively, among experimental group, control group and negative control group. The serum level of IL-4 in experimental group rats was lower than value of control group rats (t = 3.22, P < 0.05), while higher than negative control group (t = 4.17, P < 0.05). The serum level of IFN-gamma was increased significantly in experimental group rats with significant difference when compared with value of control group rats (t = 3.84, P < 0.05), while no difference was shown between experimental group and negative control group (t = 1.47, P > 0.05). CONCLUSIONS: Garlicin could increase serum level of INF-gamma and decrease serum level of IL4 significantly in allergic rhinitis rat model. It played an important role on regulating serum levels of cytokines of Thl and Th2.
