Öğe Allergic diseases in the elderly population: a single-center experience(Tubitak Scientific & Technological Research Council Turkey, 2021) Yildiz, Eray; Colkesen, Fatih; Arslan, Sevket; Evcen, Recep; Sadi Aykan, Filiz; Kilinc, Mehmet; Aytekin, GokhanBackground/aim: Although allergic diseases are generally considered to be diseases of childhood and youth, the first symptoms of allergic diseases can be seen in old age sometimes. The aim of this study was to determine the prevalence and characteristics of allergic diseases in the elderly population admitted to the allergy unit on an outpatient basis. Materials and methods: The files of the patients who applied to our clinic's allergy unit during the 8-year period were retrospectively analyzed. The data of patients aged >_ 65 years were obtained from the files of our allergy unit archive. Results: A total of 1272 patients aged >_ 65 years old were included in the study. The mean age was 70 years (range: 65-97 years). Most of the patients were female (n = 704, 55.3%). Of the patients, 887 (69.8%) presented with cutaneous symptoms, and urticaria was identified in 500 of them (56.3%). Drug hypersensitivity reactions were detected in 175 (13.7%) patients. A total of 71 (5.6%) patients had asthma, 65 (5.1%) had anaphylaxis, 48 (3.8%) had allergic rhinitis, 24 (1.9%) had hymenoptera venom allergy, and 18 (1.4%) had food allergies. Atopy history (OR = 2.323, 95% CI = 1.590-3.393, p < 0.001) and comorbidity (OR = 1.631, 95% CI = 1.050-2.533, p = 0.029) were found to be risk factors for drug hypersensitivity reactions. Male sex (OR = 3.462, 95% CI = 1.097-10.933, p = 0.034) and atopy history (OR = 14.877, 95% CI = 6.081-36.393, p < 0.001) were found to be risk factors for hymenoptera venom allergy. Conclusion: Diagnosis becomes difficult due to the perception that allergic diseases mainly affect young people. Clinical symptoms are not evident in the elderly and age-related difficulties are encountered in diagnostic tests. There is a need to develop specific guidelines for the diagnosis of allergic diseases in the elderly.Öğe Evaluation of malnutrition risk and nutrition status in adult patients with common variable immunodeficiency(Wiley, 2022) Yildiz, Eray; Arslan, Sevket; Colkesen, Fatih; Aykan, Filiz Sadi; Evcen, Recep; Kilinc, Mehmet; Aytekin, GokhanBackground The aim of this study is to determine the prevalence of malnutrition in outpatients with common variable immunodeficiency (CVID) and the utility of nutrition screening tools to detect malnutrition in these patients. Methods Fifty outpatients with CVID were included in the study. Nutrition risk for each patient was evaluated using four nutrition screening tools: Malnutrition Screening Tool (MST), Malnutrition Universal Screening Tool (MUST), Short Nutritional Assessment Questionnaire (SNAQ), and Nutritional Risk Screening 2002 (NRS-2002). Results According to MUST, MST, SNAQ, and NRS-2002, malnutrition risk was determined to be 48% (n = 24), 26% (n = 13), 20% (n = 10), and 20% (n = 10), respectively. Malnutrition was detected in 54% (n = 27) of the patients. It was found that MUST showed a better correlation in detecting malnutrition in outpatients with CVID (kappa = 0.482, P = 0.001). MUST has a higher positive and negative predictive value than other nutrition screening tools (79% and 70%, respectively). In the multivariate logistic regression analysis, it was found that low serum immunoglobulin A (IgA) levels at diagnosis increased the risk of malnutrition by similar to 15 times, and low CD19(+) B-cell counts increased the risk by approximately eight times. Conclusion The prevalence of malnutrition in patients with CVID was found to be quite high, and there was a strong correlation between malnutrition and low CD19(+) B-cell counts and low serum IgA levels. Given the high rate of malnutrition in patients with CVID, nutrition assessment is recommended rather than starting with nutrition screening.Öğe Is common variable immunodeficiency a facilitating factor for fixed drug eruptions?
