OBJECTIVETo study the characteristics of allergic reactions to common aeroallergens in young children with wheezing or allergic diseases by examining the results of skin prick test in children under 5 years old.
METHODSA total of 196 children under 5 years old, from a district of Changsha City sampled between September 1 to December 31, 2010, were assigned into two groups according to the presence of wheezing or allergic diseases: allergen screening (n=102) and control (n=94). Skin prick tests were performed on both groups.
RESULTSThe positive rate of skin prick test in the allergen screening group was 61.8% (63/102), and this was significantly higher than in the control group (9.6%, 9/94; P<0.05). In the allergen screening group, the positive rate of skin prick test in children with both recurrent wheezing and allergic rhinitis was significantly higher than in children with wheezing alone (P<0.05). The frequency of wheezing was positively correlated with a positive skin prick test (r=0.91; P<0.05). The positive rate of skin prick test for mites was significantly higher than for other aeroallergens (24.2% vs 3.5%; P<0.05) in the allergen screening group. Skin prick testing of the children for dermatophagoides farinae showed a higher positive rate than for dermatophagoides pteronyssinus (50.0% vs 14.7%; P<0.05).
CONCLUSIONSWheezing in early childhood may be associated with the occurrence of asthma. Skin prick testing contributes to the diagnosis of allergic diseases and assessment of allergic reactions to aeroallergens in children with wheezing.

OBJECTIVE:
To investigate the clinical characteristics of ocular symptoms in patients with allergic rhinitis (AR) and the impact of the ocular symptoms on patients' quality of life.
METHOD:
AR patients' history and clinical data were collected and analyzed. One hundred cases were extracted from adult patients with and without ocular symptoms in each group and their quality of life were evaluated using rhino-conjunctivitis quality of life questionnaire (RQLQ).
RESULT:
Totally 1119 cases were collected and 859 cases had ocular symptoms. Of the patients with ocular symptoms, 582 cases were mild, 234 cases were moderate, 43 cases were severe. Eye itching was the most common symptom, followed by tears, hyperemia and swelling. Patients with ocular symptoms had longer disease history than non ocular symptom group (P < 0.05). There was a positive correlation between ocular and nasal symptoms (P < 0.01); patients with ocular symptoms had more severe nasal symptoms than patients without ocular problems; while patients with moderate to severe AR had more severe ocular symptoms than mild AR patients (P < 0.01). Female patients had higher incidence (P < 0.05) and ocular symptoms score (P < 0.05) than male. Children less than 10 years old had a relative lower incidence and score of ocular symptoms. While the incidence and score had an increasing trend for patients older than fifty. There was no difference regarding the type and number of allergen in the patients with and without ocular symptom. Moreover, patients with ocular symptoms had higher scores in the domains of non-nose/eye symptoms, practical problems, ocular symptoms, emotional function and total score in RQLQ than patients without ocular symptom.
CONCLUSION
It was common for the AR patients to have ocular symptoms, and ocular symptoms had obvious influence on the patients' quality of life. So controlling of the ocular symptoms should not be ignored during the diagnosis and treatment of AR.

OBJECTIVE:
To investigate whether sublingual immunotherapy(SLIT) can take effect during the early phase in allergic rhinoconjunctivitis.
METHOD:
Sixty subjects diagnosed as allergic rhinoconjunctivitis were enrolled and divided into the SLIT group and the control group. The daily symptom and medication scores were recorded and analyzed.
RESULT:
After 4 weeks treatments, the daily symptoms score had significantly reduced in SLIT group(P<0. 05). After 6, 8, 10 weeks treatments, the daily symptoms scores of subjects in the SLIT group had all shown continuous reduction, with no consumption of medication. The comparison between daily symptom score at 4th week and those in 6th week or 8th week or 10th week in the SLIT group had shown no significant difference (all P > 0.05). Whereas, the daily symptoms score and daily medication score in control group had shown changes with fluctuations. The correlation analysis had indicated that the daily medication score in the control group had a significant negative correlation with the daily symptom score (F = 554.9, P < 0.01). No serious adverse events occurred in this study.
CONCLUSION
SLIT could take effect in patients with allergic rhinoconjunctivitis sensitive to house dust mite as fast as the 4th week.

BACKGROUNDCockroaches are an important indoor allergen source causing allergic rhinitis and asthma. The aim of this study was to investigate the cockroach prevalence in mainland of China and the cross-reactivity of IgE between cockroach and house dust mite allergen in Chinese patients.
METHODSThe cockroach sensitization pattern was based on a skin prick test (SPT) obtained from a national multicenter prevalence study, in which 6304 patients from 25 allergy centers across China participated. Factors, including different regions of China, age, gender and the correlations between the American and German cockroaches and house dust mite Der p were investigated. Eighteen out of 1236 clinical sera from south China were selected to perform the cross-inhibition assay between house dust mites and cockroaches.
RESULTSTotally 25.7% of patients were SPT positive to the American cockroach (Periplaneta Americana, Per a) and 18.7% SPT positive to the German cockroach (Blattella germanica, Bla g). The prevalence of positive cockroach SPT was higher in southern than in northern China, higher in adults than in children, and higher in males than in females. Patients had relatively low levels of cockroach SPT reactions, mainly class 1 or 2. Of the SPT positive cockroach patients, 88% were also SPT positive to house dust mite (Dermatophagoides pteronyssinus, Der p). An IgE cross-inhibition study confirmed that Der p sensitization could cause false positive SPT reactions against cockroach.
CONCLUSIONSA relatively high prevalence of cockroach sensitivity was found in mainland of China. However, a cross-inhibition study showed that only a small number of patients appear to have Bla g and/or Per a as primary sensitizing source. The importance of cockroaches as a risk factor for sensitization and triggers of allergic symptoms in mainland of China needs to be further investigated.

It has been demonstrated that spider mites such as the two-spotted spider mite (Tetranychus urticae) are important allergens for fruit farmers. A total of 2,467 adults (795 metropolitan urban, 788 non-metropolitan urban, and 884 rural subjects) were enrolled. They responded to the questionnaire, and underwent methacholine bronchial provocation tests as well as skin prick tests to locally common aeroallergens including the two-spotted spider mite. The prevalences of asthma and rhinitis as reported on the questionnaire were 7.8% and 16.4% of adults aged 20-35, 9.4% and 24.7% of those 36-50, and 17.7% and 21.7% of those older than 50, respectively. Among the older group, the two-spotted spider mite was the most common sensitizing allergen, although it was second of that of house dust mites among the other two age groups. Sensitization to the two-spotted spider mite was significantly associated with the prevalence of asthma and rhinitis among the younger age group, and associated with the prevalence of rhinitis among the older age group. The twospotted spider mite might be a common sensitizing allergen in the general population of adults, and sensitization to this mite may play a role in the manifestation of asthma and rhinitis symptoms during adulthood.

OBJECTIVE:
To investigate the correlation between serum specific immunoglobin E(sIgE) and skin prick test(SPT) and their differences of the positive rate.
METHOD:
One hundred and nine patients with allergic rhinitis were detected the serum slgE. The patients had positive symptoms and signs, positive SPT results with at least one allergen.
RESULT:
Specific IgE and SPT results of Dp,Df and Artemisia showed a positive correlation (r = 0.520, 0.4413, 0.764, P < 0.01). sIgE positive rates were 55.0%, 54.1% and 17.4% for Dp, Df and Artemisia respectively, whereas SPT positive rates were 68.8%,79.8% and 27.5% respectively. The difference between the positive rates of the sIgE and SPT was significant (chi2 = 27.93,18. 20,60. 60, are P< 0.01).
CONCLUSION
There was a good correlation between specific IgE and SPT. SPT is more sensitive than sIgE, but SPT can not substitute for slgE,vice versa.

Citrus red mite (CRM) is known as the most common sensitizing allergen in subjects with asthma and rhinitis working on citrus farms. The aim of this study is to evaluate the role of specific IgG1 (slgG1) and specific IgG4 (slgG4) to CRM in citrus farmers. Questionnaire survey and skin prick test including CRM antigen was done by 136 workers. Specific IgE (slgE), slgG1 and slgG4 to CRM were detected by enzyme-linked immunosorbent assay (ELISA). CRM-sensitive-asthma was diagnosed upon presence of asthmatic symptoms by questionnaire, airway hyperresponsiveness to methacholine and slgE to CRM. CRM-sensitive rhinitis was diagnosed upon presence of rhinitis symptoms and slgE to CRM. Eleven (8.1+ACU-) had CRM-sensitive asthma and 25 (18.4+ACU-) had CRM-sensitive rhinitis. Significant association was noted between presence of asthmatic symptoms and slgE or slgG4 (p+ADw-0.05, respectively), while no significant association was noted in slgG1 (p+AD4-0.05). Significant association was noted in the prevalence between slgG4 and slgE (p+ADw-0.05), while no significant association was noted between slgG1 and slgG4 or slgE (p+ADw-0.05, respectively). There was a significant correlation between slgE and slgG4 level (r+AD0-0.39, p+ADw-0.05). These findings suggest that the presence of slgG1 to CRM is response to CRM exposure, and further studies will be needed to evaluate the role of slgG4.Citrus red mite (CRM) is known as the most common sensitizing allergen in subjects with asthma and rhinitis working on citrus farms.
