Quality of life (QoL) is an important consideration among asthma sufferers. The Pediatric Asthma Quality of Life Questionnaire (PAQLQ) is one of the most widely used instruments for measuring health-related QoL in children with asthma. The standardized version of PAQLQ contains 23 questions in three domains, i.e., activity limitation, symptoms and emotional function. The objective of this study was to validate the Thai-translated version of the PAQLQ. The study design consisted of a five-week single cohort study. Patients recorded symptoms, and peak expiratory flow rate (PEFR) each morning and evening during the first and fifth week of the study in asthma diary. At each clinic visit, a trained-interviewer administered the PAQLQ and performed spirometric measurements. Fifty-one children, ages between 7 and 17 yr participated in the study. Scores from the asthma diary were used to classify patients into stable vs. unstable groups. The construct validity of the questionnaire was confirmed in both cross-sectional and longitudinal studies by demonstrating correlations between various PAQLQ domains with clinical asthma parameters (asthma diary, beta-agonist use and PEFR). There was high internal consistency for scores of the three domains (Cronbach's alpha-coefficient = 0.83-0.95). For those with stable asthma, the reliability of PAQLQ was good for the rating scale (intra-class correlation coefficient--ICC = 0.84) and for total score (alpha = 0.97) indicating high reproducibility of the PAQLQ. The significant difference of changes QoL scores between stable and unstable groups was observed in all domains. We conclude that the Thai version of PAQLQ is valid and reliable for implementing in Thai children with asthma. 相似文献

PurposeTolerance to shrimp has been reported in some patients with a history of shrimp allergy. The predictors of the natural resolution of shrimp allergy have not been widely explored. This study aimed to investigate the role of specific IgE (sIgE) and specific IgG4 (sIgG4) to shrimp extracts and the cross-reactive shrimp allergens tropomyosin (TM), arginine kinase (AK) and myosin light-chain (MLC), as markers of persistent or resolved shrimp allergy (PSA or RSA).MethodsSeventeen patients with a 10-year history of allergy to Penaeus monodon (Pm) and/or Macrobachium rosenbergii (Mr) were recruited. Oral shrimp challenges identified 10 patients with PSA and 7 patients with RSA. Sera from these patients were evaluated for sIgE and sIgG4 to Mr and Pm extracts as well as to TM, AK and MLC.ResultsThe levels of sIgE to Mr and Pm extracts were lower in the RSA than in the PSA groups (P = 0.05 and P = 0.008, respectively), but sIgG4 or sIgG4:sIgE ratio did not show statistical significance. The sIgE to AK and MLC, but not TM, were lower in the RSA group than in the PSA group (P = 0.009 and P = 0.0008, respectively). There was no difference in sIgG4 to TM, AK and MLC between both groups. The ratio of sIgG4:sIgE to MLC, but not TM or AK, was higher in the RSA than in the PSA group (P = 0.02). A higher diversity of sIgE to shrimp components was found in the PSA group than in the RSA group (P = 0.006).ConclusionsSpecific bioassays can be used to identify patients with RSA. Oral shrimp challenges in these patients may provide a higher rate of passing the challenges and finally reintroducing shrimp in their diet. 相似文献

Purpose
Patients with 22q11.2 deletion syndrome have a variable decrease in immunological parameters, especially regarding T cell counts. The aim of this study was to investigate immunological change over time and factors associated with immunological recovery among patients with 22q11.2 deletion syndrome.Methods
Patients with 22q11.2 deletion syndrome diagnosed by fluorescence in situ hybridization (FISH) were studied. Immunological parameters were evaluated every 6 months until patients returned to normal. Infection and vaccination histories were recorded and analyzed, and Kaplan-Meier survival curves were plotted to describe resolution of immunodeficiency.Results
Forty-nine patients with an age range of 4 to 222 months were included. Twenty-five (51%) patients were female. In hypocalcemia, the odds ratio for CD4 lymphopenia was 17.03 (95%CI 1.82–159.23; p value = 0.01). Thirty patients (61.2%) exhibited decreased CD4+ T cell numbers, which returned to normal level in 18 (60%) patients. Median age of CD4+ T cell resolution was 2.5 years. T cell functions were abnormal in three patients. T cell functions returned to normal in all patients at a median age of 1.1 years. Six patients (13.5%) had abnormal serum immunoglobulin levels, with levels improving in four patients at 1.4 years of age. The most common infection was pneumonia (69.4%). BCG vaccination was administered in 47 of 49 patients at birth. Among 32 patients who had T cell defect, one patient developed BCGitis and one developed disseminated BCG.Conclusion
Immunodeficiencies identified among patients with 22q11.2 deletion syndrome were T cell defect (65.3%) and decreased immunoglobulin levels (12.2%). Median age of CD4 resolution was 2.5 years.4.

To study prevalence of allergen sensitization among asthmatics in Thailand, skin prick tests (SPT) were performed in 84 pediatric, 71 adult asthmatics and 71 adult volunteers. Allergen extracts used for testing included common allergens in Thailand and in Singapore. The incidence of positive SPT to any allergen among the three groups (childhood, adult patients and adult controls) were 64.3%, 43.7% and 35.2%, respectively. Dermatophagoides were the most common allergens sensitized by both pediatric (58.3%) and adult asthmatics (40.8%). Twenty-four children (28.6%) and 8 adult patients (11.3%) were sensitized to storage mites (Blomia tropicalis and/or Austroglyciphagus malaysiensis). All patients sensitized to Blomia tropicalis were sensitized to Dermatophagoides. Twenty-seven percent and 15.5% of childhood and adult asthmatics were sensitized to cockroach allergens. The rates of sensitization to oil palm pollen in childhood and adult asthmatics were 8.3% and 5.6%, respectively. Sensitization to other pollens and spores were less than 5%. This study confirms the importance of Dermatophagoides among Thai asthmatics. 相似文献

Prevalence of childhood asthma appears to be increasing worldwide. In Thailand, the prevalence of childhood asthma increased from 4.2% to 13% within the past decade. The last epidemiologic survey in Thailand utilized the International Study of Asthma and Allergies in Childhood (ISAAC) phase I questionnaire translated into Thai language. Language in the questionnaire can affect the reliability and validity of results of the survey. The purpose of this study is to determine common Thai wordings actually used by Thai children and adolescents to describe wheeze, chest tightness, shortness of breath and dyspnea. Sixty asthmatic Thai children, aged 9.2–18 years with asthmatic attacks less than 1 yr prior to the study, and 178 age‐matched controls were recruited into the study. Asthmatic children spontaneously expressed their terms describing their asthma symptoms (in Thai) and then answered a preoutlined questionnaire regarding asthma terminology during an interview session after viewing the severe attack scene of the International ISAAC video questionnaire. Controls responded only to the preoutlined questionnaire after viewing the video scene. Of the 60 asthmatic children (38 males and 22 females, mean age 11.9 yr), 75% had their last asthmatic attacks within 2 months prior to the study. Wheeze was referred to as ‘’ and ‘/wi:d/’ in 50% and 33% of patients, respectively, and ‘’ in 93.8% among controls. Using only the word ‘/wi:d/’ in our previous ISAAC‐I survey, as it sounded like the English word ‘wheeze’, it appears that up to 67% of the cases could have been missed. Dyspnea was referred to as rapid breathing and feeling tired in 78.2% of cases and as rapid and difficult breathing in 76.3% of controls. Chest tightness was referred to as chest discomfort in 65.7%. Shortness of breath was referred to as not being able to catch a breath, too short a breath, not enough breath and feeling suffocated in 88.8%. Local terms for asthma symptoms should be established and validated into each language to obtain reliable epidemiologic data. 相似文献

Introduction Early diagnosis and treatment are keys to improve survival of patients with primary immunodeficiency diseases (PID). The clinical
characteristics of these patients in Thailand were not well defined.
Objective This study aimed to determine the clinical characteristics and outcomes of patients with PID in Thailand.
Methods Medical records of PID patients in the past 18 years were reviewed.
Results Sixty-seven children were registered. Antibody deficiencies were the most common PID (52.2%), followed by combined T cell
and B cell immunodeficiencies (25.4%), other well-defined immunodeficiency syndromes (11.9%), and phagocytic defects (10.4%).
The most common presentations of antibody deficiencies, combined T cell and B cell immunodeficiencies, and phagocytic defects
were infection in the upper respiratory tract (74.3%), gastrointestinal tract (82.4%), and skin (85.7%), respectively. The
highest mortality rate (52.9%) was found in severe combined immunodeficiency.
Conclusion These results provide clinical features of PID in Thailand. Knowing these features will lead to prompt diagnosis and appropriate
management. 相似文献

Allergic rhinitis is one of the most common chronic disorders in children. It is also one of the most common causes of absence from school. This study reports on the efficacy and safety of a twice-daily oral dose of fexofenadine HCl 30 mg in Asian children aged 6-11 years diagnosed with seasonal or perennial allergic rhinitis. A total of 100 children with a history of allergic rhinitis for more than one year and a positive prick skin test response to at least one of the common aeroallergens in Thailand were enrolled in this multi-center, open-label, non comparative study. The severity of individual symptoms such as sneezing, rhinitis, etc. and adverse events were recorded in diary cards by the patients in form of scores as well as by the investigator at each visit. The total symptom score (TSS) with or without blocked nose at baseline, week 1 and week 2 was recorded. The TSS was defined as the sum of the individual symptom scores except for the nasal blockage score, as nasal blockage was not expected to respond to antihistamine treatment. Only patients with a total symptom score > or = 6 were included in the study. There was a statistically significant improvement at p < 0.01 for the TSS with or without blocked nose and for each symptom score such as blocked nose, sneezing, rhinorrhea, itchy nose/palate and/or throat, and itchy/watery/red eyes from baseline to week 1 and week 2. Additionally, there was a statistically significant improvement between week 1 and week 2 for itchy nose/palate and/or throat and itchy/watery/red eyes (p < 0.05). The Kappa measure of agreement was statistically significant at p < 0.001 between investigator's and patient's/parent's assessment, indicating the same degree of satisfaction with the overall effectiveness of the treatment. Fexofenadine 30 mg bid is effective in reducing the total symptom score of allergic rhinitis including blocked nose and is generally well tolerated. It is not cardiotoxic and is safe for pediatric patients as young as 6 years of age. 相似文献
