RESUMO
BACKGROUND/AIMS@#Chronic urticaria (CU) is a common skin disorder characterized by wheals and pruritus lasting more than 6 weeks. Due to its long duration and changeable symptoms, the quality of life (QOL) of patients with CU can be impaired substantially. We evaluated the CU-QOL, a previously validated CU-specific QOL measure, and investigated factors influencing QOL in chronic spontaneous urticaria (CSU) patients.@*METHODS@#A hospital-based cross-sectional study was performed on 390 adult patients diagnosed with CSU from March 2009 to December 2012 at the Allergy and Clinical Immunology Clinic at Ajou University Hospital. The CU-QOL questionnaire, urticaria activity score (UAS), combined angioedema, and serum total immunoglobulin E (IgE) levels were investigated.@*RESULTS@#The average CU-QOL score obtained from the questionnaire was 70.6 (of 100 points). The CU-QOL scores correlated significantly with the UAS, particularly with the 15-point UAS (UAS-15; coefficient –0.532, p < 0.01) rather than the 6-point UAS (–0.502, p < 0.01). The patients presenting with angioedema and urticaria had poorer scores in the urticaria symptom domain than those with urticaria alone (37.4 vs. 46.9, p = 0.004). Log-transformed serum total IgE levels correlated significantly with CU-QOL (–0.131, p < 0.05). Multivariate regression models indicated that severe CU (UAS-15 score ≥ 13), log (total IgE), and the presence of angioedema were significant predictors of impaired CU-QOL (< 85 points).@*CONCLUSIONS@#CU has a substantial negative impact on QOL. The assessment of UAS-15, total IgE, and the presence of angioedema can be useful to predict QOL of the patients with CSU.
RESUMO
Eosinophilic gastroenteritis (EG) is a rare disease characterized by massive eosinophilic infiltration of gastrointestinal tissue, peripheral eosinophilia, and nonspecific gastrointestinal symptoms. The mucosal type of EG commonly presented with malabsorption and anemia. However, the role of food allergy as a stimulus to EG has not yet been clearly defined. A 27-year-old man was referred to the Emergency Department with dyspepsia and leg swelling. The initial laboratory test should as follows: hemoglobin level, 6.4 g/dL; white blood cell count, 7,400/microL with 24.4% of eosinophil fraction; serum total protein, 3.9 g/dL; albumin level, 2.8 g/dL. Gastric endoscopy ruled out gastrointestinal bleeding showed multiple nodular raised lesions on the gastric antrum, which revealed increased eosinophilic infiltration (above 100/high power field). He had experienced nausea whenever eating beef, porks or fish. High serum specific IgE levels to offending foods (beef, 0.82 kU/L; pork, 0.83 kU/L; egg white, 0.40 kU/L; egg yolk, 0.54 kU/L; milk, 0.81 kU/L) were noted. He was instructed strictly to avoid food allergens with oral prednisolone therapy. Approximately 6 months after offending food restriction, the eosinophil count fell down to 400/microL, the hemoglobin level was returned to 11.5 g/dL and the serum albumin level was increased to 4.1 g/dL. We report a case of EG caused by multiple food allergy which leads to malabsorption and iron-deficiency anemia.
