Epidemiological investigation of allergic rhinitis in Ningxia / 中华耳鼻咽喉头颈外科杂志

Objective@#To investigate the epidemiological characteristics of allergic rhinitis (AR) in Ningxia and to analyze its related factors.@*Methods@#From March to September of 2013, a multi-stage and cluster sampling method was used to investigate the diagnosis and treatment of AR in Ningxia Area (3 years and above). Guidelines for diagnosis and treatment of allergic rhinitis (2009, Wuyishan) was used as the basis for the diagnosis of adult AR, while Guidelines for diagnosis and treatment of pediatric allergic rhinitis (2010, Chongqing) was used as the basis for children. SPSS 16.0 software was used to complete the statistical analysis.@*Results@#The total number of questionnaires was 6 000, and the number of effective questionnaire was 5 236, the recovery rate was 87.27%. With 684 cases diagnosed of AR, the prevalence of AR in Ningxia was 13.06% (684/5 236), including 13.40% (325/2 425) of males, 12.77% (359/2 811) of females. The difference was not statistically significant (χ2=0.456, P>0.05). There was significant difference in the prevalence between Hui and Han [14.35% (452/3 150) vs 11.12% (232/2 086), χ2=11.51, P<0.05]. According to ARIA criteria, persistent AR was 27.63% (189/684), intermittent AR was 72.37% (495/684). The month with highest incidence of AR in Ningxia Area was September, accounting for 71.78% (491/684). The prevalence of urban population was 14.54%, with the prevalence of rural population was 11.90%, and the difference was significant between urban and rural residents (χ2=7.90, P<0.05). The age group with highest prevalence rate was 21~30 years old. The main inhalation allergens were mugwort (68.42%), weeds (58.48%) and ragweed (55.56%). The main dietary allergens were wheat flour (14.33%), peanut (13.74%) and walnut kernel (11.99%). The most common complication was allergic conjunctivitis [82.02% (561/684)].@*Conclusion@#The epidemiology of AR in Ningxia Area is preliminarily understood, which will provide the epidemiological evidence for the prevention and treatment of AR and the formulation of public health policy.

The correlation of allergic rhinitis and trace elements in Ningxia region / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the correlation of allergic rhinitis and trace elements and to provide a reference for clinical diagnosis, treatment and prevention of allergic rhinitis.</p><p><b>METHODS</b>One hundred and six patients were diagnosed as allergic rhinitis in General Hospital of Ningxia Medical University between January and December in 2010, including 48 cases of perennial allergic rhinitis and 58 cases of seasonal allergic rhinitis. In the same time, one hundred and three healthy volunteers were selected as control. Intravenous blood 3-5 ml were obtained from all subjects both in experimental group and in control group. The content of Ca, Ni, Fe, Mg, Zn, Sr, Mn, Cu, Se in serum and hair was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The t-test (SPSS 16.0) was used to compare the results of trace elements in serum between allergic rhinitis and control group.</p><p><b>RESULTS</b>The testing results of trace elements in AR patients serum and normal controls serum were as follows: Cu, Ni (1 002.18 ± 104.62) µg/L, (21.58 ± 5.54) mg/L were super than control group, (832.78 ± 50.45) µg/L, (17.04 ± 4.93) mg/L (t value was 15.545, 5.154, both P < 0.05). But the content of Zn, Se (793.48 ± 46.88) µg/L, (84.25 ± 12.77) µg/L lower than control group (908.53 ± 31.26) µg/L, (98.35 ± 15.21) µg/L (t value was -24.175 and -7.797, both P < 0.05) . The testing results of trace elements in AR patients hair and normal controls hair were as follows: Cu, Ni (42.43 ± 5.03) µg/g, (31.72 ± 5.49) µg/g were super than control group, (23.00 ± 4.45) µg/g, (8.94 ± 7.53) µg/g (t value was -8.633 and 4.236, both P < 0.05). But the content of Zn, Se (92.16 ± 4.54) µg/g , (0.28 ± 0.04) µg/g lower than control group (189.09 ± 8.45) µg/g, (0.39 ± 0.06) µg/g (t value was -28.71 and -8.633, both P < 0.05).</p><p><b>CONCLUSIONS</b>The content of Zn, Se in AR patients serum are lower than that in control group. But the content of Cu, Ni in AR patients serum are super than that in control group. There are no significant difference of trace elements in the serum between pennial allergic rhinitis and seasonal allergic rhinitis.</p>

The correlation study of allergic rhinitis and chronic rhinosinusitis with nasal polyps in Ningxia region / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the correlation of allergic rhinitis and chronic rhinosinusitis with nasal polyps in the Ningxia region.@*METHOD@#One hundred and sixteen patients diagnosed with allergic rhinitis, chronic rhinosinusitis with nasal polyps, allergic rhinitis combined with chronic rhinosinusitis with nasal polyps in the department of Otorhinolaryngology Head and Neck Surgery, Ningxia Medical University Hospital from 2009 January to December was analysed in this study, followed by grouping the experimental group I: allergic rhinitis(AR) group (46 cases), the experimental group II: chronic rhinosinusitis with nasal polyps group (46 cases), the experimental group III: allergic rhinitis combined with chronic rhinosinusitis with nasal polyps group (24 cases), and the normal control group (31 cases). The skin prick test was used and the serum specific IgE concentration of selected objects was measured by enzyme linked immunosorbent assay.@*RESULT@#(1) The positive rate of specific IgE in the experimental group I was 83.3%, the concentrated for specific IgE mainly graded in 0 to 3 level, The total positive rate of specific IgE in the experimental group II and III were 75.0% and 87.5%. (2) The specific IgE concentration in the experimental group I, II , III and control group were 10.33 +/- 2.12 (kU/L), 8.43 +/- 2.23 (kU/L), 5.28 +/- 2.16 (kU/L), 1.03 +/- 3.96 (kU/L), respectively. The data analyzed using ANOVA showed that the specific IgE concentration in the experimental group I, II, III compared with the control group was significantly different;@*CONCLUSION@#(1) The specific IgE concentration in the Ningxia region of allergic rhinitis, chronic rhinosinusitis with nasal polyps were graded in 0 to 3 level, mainly graded in 1 level and lower than other regions. The positive rates of the skin prick test about Wormwood, German cockroach, house dust mites and pollen IV allergen were relatively higher in Ningxia region. (2) The specific IgE concentration was relatively higher in the allergic rhinitis patients combined with chronic rhinosinusitis with nasal polyps. Allergic rhinitis may promote the development of chronic rhinosinusitis with nasal polyps.
