Background: There have been few reports on the characteristics of adverse drug reactions (ADRs) in elderly patients among the Korean population. Objective: To investigate the characteristics of ADRs in elderly patients compared with those in younger ones. Method: ADRs were collected from a spontaneous reporting system at our university hospital in 2008. Characteristics including underlying diseases, duration of hospitalization, clinical manifestations, culprit drugs and number of concomitant medications were compared between the young (<65 years) and elderly (≥65 years) groups. Result: A total of 528 ADRs occurred in 513 patients, and 120 ADRs (22.7%) occurred in 116 elderly patients. Their mean age was 71.6 years. Antibiotics (45.8%) were the most common culprit drugs. The prevalence of ADRs due to cardiovascular drugs was significantly higher in the elderly group (9.2%) than in the young group (2.9%, P=0.003). The most prevalent clinical types were skin manifestations (40.5%), gastrointestinal abnormalities (28.4%) and systemic reactions (23.5%) in both groups. Renal function abnormalities were significantly more prevalent in the elderly group (4.2%) than in the young group (0.5%, P=0.008). The mean number of concomitant medications was significantly higher in the elderly group (6.5±4.6) than in the young group (1.9±3.9). Conclusion: For the early detection of ADRs in elderly patients, close monitoring of cardiovascular drug use and renal function are recommended. (Korean J Asthma Allergy Clin Immunol 2010;30:216-221)

Styrene, a common solvent and volatile organic compound (VOC), is widely used in the factories of plastics, resins, insulators, coatings, and paints. While toluene diisocyanate (TDI) is a well-known causative agent of asthma, styrene has been rarely reported to cause occupational asthma (OA). We report a 50-year-old repairman with OA due to both styrene and TDI in whose job was filling cracks and flattening the surface of vehicles with styrene-containing plaster`s putty, followed by spray painting. He suffered from cough, dyspnea durings the work with putty. He presented with a 2-year history of asthma and allergic rhinitis. The level of serum total IgE and sputum eosinophils were 2,878 IU/L and 63%, respectively. The methacholine challenge test was positive (PC20 0.59 mg/mL). The bronchoprovacation tests with TDI and styrene showed early and dual responses, respectively. Currently, he is in well-controlled state with the use of a combination of inhaled corticosteroid and long acting β2-agonist after the avoidance of the causative agents.

Urticaria is a common cutaneous disease characterized by recurrent and transient wheals and pruritus, sometimes accompanied angioedema. The classification of urticaria is based on the duration of the disease and whether extrinsic triggers are identified or not. Acute urticaria is usually occurred by specific causes, such as drug, food, and infection, etc. Therefore, acute urticaria can be remitted within 6 weeks just by avoiding the exposure to the causes. However, chronic urticaria defined as repeatedly occurred itchy wheals and/or angioedema for at least 6 weeks, has a significant effect on patients’ quality of life. Chronic inducible urticaria can be triggered by various physical stimuli including dermographism, delayed pressure, cold, heat, cholinergic stimuli, sunlight, and exercise. Chronic spontaneous urticaria (CSU) is diagnosed when no specific extrinsic cause is identified in the patients. CSU due to autoimmune mechanism accounts for 30-50%, autologous serum skin test and anti-thyroid autoantibody can be evaluated. However, various physical stimuli, emotional or physical stress, drugs, particularly aspirin and non-steroidal anti-inflammatory drugs can exacerbate urticaria in 30-75% of patients with CSU. Allergic diseases and autoimmune diseases are more common in CSU patients than in general populations. To assess the severity of urticaria and to adjust treatment step, urticaria activity score over 7 days, calculated by the number of wheals and the severity of pruritus, is recommended by recent international guidelines.

Chronic urticaria (CU) is defined by the presence of urticaria that has been continuously or intermittently for a period of 6 weeks or longer. The prevalence of CU in the general population has been estimated to range from 0.5% to 5%. Correct diagnosis and proper management for CU is essential to improve the quality of care. To date, several practical guidelines have been available for practitioners. In this article, we reviewed and summarized the epidemiology, pathogenesis, diagnosis, and management based on case reports and studies of CU from Korea and the other part of world, and recently published guidelines. Although there are many controversies, this report for CU would provide a clinical guidance for healthcare professionals in Korea.

Background: Cefaclor is commonly prescribed for various infectious diseases. It is known as a major causative antibiotic that induces drug hypersensitivity reactions. The aim of this study is to evaluate clinical and immunologic features of cefaclor immediate hypersensitivity. Methods: We conducted a retrospective study on the patients with histories of immediate hypersensitivity to cefaclor at Ajou University Hospital between January 2002 and February 2011. Serum specific IgE to cefaclor was measured using the ImmunoCAP system. Results: Fifty patients were enrolled in this study. The most common immediate hypersensitivity reaction was anaphylaxis (38/50, 76%), followed by urticaria/angioedema (12/50, 24%). High serum specific IgE to cefaclor was noted in 40 patients (80%). There were no significant differences in clinical parameters whether the patients had serum specific IgE or not, except that serum total IgE level was higher in patients with high serum specific IgE to cefaclor (P=0.042). Serum specific IgE to penicillin was detected in 26.1% of the patients with high serum specific IgE to cefaclor, while serum specific IgE to aminopenicillin was not found in any of the study subjects. Conclusion: Immediate hypersensitivity to cefaclor occurred mostly through the IgE-mediated mechanism, and anaphylaxis was the most common manifestation. Cross reactivity with penicillin was noted in 26% of the patients, but no cross reactivity with aminopenicillin was noted. (Korean J Asthma Allergy Clin Immunol 2011;31:192-198)

Background: Cytokeratin 18 (CK18) protein was identified as an airway epithelial cell antigen associated with nonallergic asthma. Objective: We evaluated an association between IgG autoantibodies to CK18 protein and clinical severity of asthma in this study. Method: Severe asthma was defined as when patients had experienced at least one severe asthmatic exacerbation requiring an emergency room visit or admission in the last year despite continuous typical therapies. Moderate asthma was defined as when patients had been controlled by typical therapies without severe asthmatic exacerbation in the last year. Mild asthma was defined as when patients experienced intermittent asthmatic symptoms and did not need continuous anti-asthmatic treatments in the last year. IgG autoantibodies to CK18 protein were detected in serum samples by immunoblot analysis Result: IgG autoantibodies to CK18 protein were detected in 48 of 161 asthmatic patients (29.8%) and 5 of 58 healthy controls (8.6%) (P=0.002). IgG autoantibodies to CK18 protein were detected in 1 of 20 patients with mild asthma (5.0%), 22 of 63 patients with moderate asthma (34.9%), and 25 of 78 patients with severe asthma (32.1%)(P<0.001). Conclusion: These findings suggest that IgG autoantibodies to CK18 protein could be a biological marker for moderate-to-severe asthma requiring continuous medical treatment.

Background: There were a few reports about the clinical features of bee venom allergy in Korea, which had a limitation of small study subjects. Objective: The aim of the present study was to observe the clinical features of bee venom allergy and to evaluate the risk factors associated with severe systemic reactions. Method: Fifty-two patients presenting local and systemic bee venom allergies were enrolled, and skin prick test was performed to determine atopy status. Serum specific IgE antibodies to causative bee venom (honeybee, yellow jacket, yellow hornet, white faced hornet, and paper wasp) were detected by immunoCAP or RIA. Result: Thirty-three patients (63.5%) were male and nineteen patients (36.5%) were female. Local reaction was developed in nine (17.3%) patients and systemic reaction in fourty-three (82.7%) patients. Bee venom allergy was developed mainly in adults during summer, and the major causative allergen was honeybee. The presence of serum specific IgE to honeybee was significantly related with the development of severe systemic reaction (P=0.02). Severe systemic reaction was more common in males than in females (P<0.05). Conclusion: Honeybee sting and male gender are noted as significant risk factors for severe systemic reaction after bee sting in this country. (Korean J Asthma Allergy Clin Immunol 2006;26:145-150)

Purpose: Assessment of the severity and clinical course of asthma is important for effective disease control. Cognitive and physical impairments occur due to the aging process, which may impact on asthma control. We aimed to evaluate the impact of cognitive function on the assessment of asthma control in older asthmatics as a prospective interventional trial. Methods: A total of 50 mild to moderate asthmatics over 60 years of age were enrolled. Three questionnaires were used: the asthma control test (ACT), the asthma-specific quality of life, and the Korean version of the Short Form of the Geriatric Depression Scale. The Seoul neuropsychological screening battery-dementia version (SNSB-D), Korean version of the Mini-Mental Status Examination, and the Seoul instrumental activities of daily living scale were applied for neuropsychological assessment. Results: The mean patient age was 67.0±4.9 years, and 30 patients (60.0%) were female. The sensitivity and specificity of the ACT for determining well-controlled asthma were 91.7% and 39.5%, respectively. Regarding neuropsychological assessment, 22 patients (44%) had mild cognitive impairment, 4 (8.7%) had dementia, and 17 (34%) had depression. Total SNSB-D score was significantly higher in patients with an ACT score of ≥20 (P=0.015). The ACT scores were significantly associated with SNSB-D results in analyses adjusted for age, sex, education duration, lung function, and depression (P=0.004). Conclusion: We found significant positive correlations between cognitive functions, as measured by SNSB-D, and asthma control status, as measured by ACT scores, in older patients with asthma. Therefore, cognitive impairment may be associated with poor asthma control in older asthmatics. (Allergy Asthma Respir Dis 2017:5:34-40)
