Öğe A Rare Presentation of Coeliac Disease; Intractable Itching with Recurrent Heart Attack and Dermatitis Herpetiformis(Bilimsel Tip Yayinevi, 2021) Alan Yalim, Sumeyra; Dumanoglu, Betul; Poyraz, Merve; Alpagat, Gulistan; Baccioglu, Ayse; Kalpaklioglu, Ayse FusunCoeliac disease (CD) is a systemic disease of the unwarranted immune reaction to gluten and is associated with a 10% increased risk of cardiovascular disease. Here we present a patient with recurrent myocardial ischemia and intractable itching who was eventually diagnosed with CD. A 53-year-old man presented to the allergy department due to intractable itching that was resistant to antihistamine therapy. In addition, despite successful percutaneous intervention with stent implantation to the right coronary artery, there was an ST segment elevation with myocardial infarction (MI) in the lower wall that had occurred three times. After dermatitis herpetiformis was reported as a result of the biopsy performed from the lesions, duodenal biopsy confirmed the diagnosis of CD. Diagnosis of CD with atypical presentation can be difficult. Cardiovascular risk is increased in patients with celiac disease compared to the normal population. Itching is an important symptom that needs to be evaluated in detail, even without the typical gastrointestinal manifestations of CD.Öğe Adverse effect of VEGFR-2 (rs1870377) polymorphism on the clinical course of COVID-19 in females and males in an age-dependent manner(Elsevier, 2023) Kocakap, Derya Beyza Sayin; Kaygusuz, Sedat; Aksoy, Emel; Sahin, Omer; Baccioglu, Ayse; Ekici, Aydanur; Kalpaklioglu, Ayse FusunThe COVID-19 pandemic has affected people worldwide with varying clinical presentations ranging from mild to severe or fatal, and studies have found that age, gender, and some comorbidities can influence the severity of the disease. It would be valuable to have genetic markers that might help predict the likely outcome of infection. For this objective, genes encoding VEGFR-2 (rs1870377), CCR5D32 (rs333), and TLR3 (rs5743313) were analyzed for polymorphisms in the peripheral blood of 160 COVID-19 patients before COVID-19 vaccine was available in Turkiye. We observed that possession of the VEGFR-2 rs1870377 mutant allele increased the risk of severe/moderate disease in females and subjects >= 65 years of age, but was protective in males <65 years of age. Other significant results were that the CCR5D32 allele was protective against severe disease in subjects >= 65 years of age, while TLR3 rs5743313 polymorphism was found to be protective against severe/moderate illness in males <65 years of age. The VEGFR-2 rs1870377 mutant allele was a risk factor for severe/moderate disease, particularly in females over the age of 65. These findings suggest that genetic polymorphisms have an age-and sex-dependent influence on the severity of COVID-19, and the VEGFR-2 rs1870377 mutant allele could be a potential predictor of disease severity.(c) 2023 Institut Pasteur.

The aim of this study was to examine changes on asthma clinic and oxidant homeostasis due to air pollution between allergic asthma (AA) and non-allergic asthma (NA) phenotypes. Methods This prospective, case-control study included patients with well-controlled asthma under regular treatment (n = 57) and healthy individuals (n = 51). Of asthma patients, 22 had AA and 35 had NA phenotypes. Respiratory symptoms, pulmonary function tests, serum total antioxidant status (TAS) and total oxidant status (TOS), and thiol/disulfide levels were compared between the most (V-1) and least (V-2) air-polluted times. Results High air pollution exposure resulted to an increase in the frequency of respiratory symptoms and serum inflammation markers in both asthmatic and healthy individuals. Frequency of dyspnea and cough in AA and rhinitis in NA decreased from V-1 to V-2. Hospitalization due to asthma exacerbation, systemic corticosteroid use, and eosinophil counts were more frequent in NA group than AA in V1. An increase of blood eosinophil counts was observed in AA group at the same visit. Mean TAS and TOS levels were higher in asthma group than control group, and the decline in TAS and TOS levels from V-1 to V-2 was seen only in NA. All thiols decreased and SH/total SH ratios significantly increased from V-1 to V-2 in all groups. Conclusion This study demonstrates that air pollution affects both asthma patients and healthy individuals. Through oxidant-antioxidant and thiol pathways, however, it adversely affects respiratory system of asthma patients, at a greater extent, than healthy individuals.Öğe Allergic Contact Dermatitis due to Medical Mask; A Case Report(BILIMSEL TIP YAYINEVI, 2020) Alpagat, Gulistan; Dumanoglu, Betul; Poyraz, Merve; Alan Yalim, Sumeyra; Baccioglu, Ayse; Kalpaklioglu, Ayse FusunAllergic contact dermatitis occurs as a result of delayed hypersensitivity reaction caused by various exogenous substances. Here, a case of allergic contact dermatitis due to medical mask use is presented. A 39-year-old female patient was admitted to Allergy outpatient clinic with complaints of red and itchy maculopapular lesions, and small blisters on the cheeks, nasolabial folds, chin and neck under the chin that started three days ago. She had no chronic illness, massive sunshine exposure, history of systemic and topical medication intake and cosmetic use. The patient has been using washable masks for the whole COVID-19 pandemic period, however she used medical masks instead of washable ones 15 days ago once and for the last two days before the beginning of her complaints. Even though there was no reaction in her first contact, the above dermatitis lesions restricted to mask area developed 24-48 hrs after starting to use it for the second time. Allergic contact dermatitis was diagnosed due to skin lesions suitable with dermatitis and occurrence of the reaction after the second contact to a suspicious substance. She was recommended to stop using medical masks, and a treatment of oral antihistamine and topical steroid was prescribed. After her complaints resolved completely, a challenge with a different brand of medical mask was performed, and no reaction was observed. As a result, this case implicates that allergic contact dermatitis may occur due to using medical masks, and it is important to use masks with standardized approval since they are essential in preventing airborne infections including corona virus.Öğe Amoxicillin/Clavulanic Acid-Induced Symmetric Drug-Related Intertrigious and Flexural Exanthema(Springernature, 2023) Alpagat, Gulistan; Baccioglu, Ayse; Dumanoglu, Betul; Yalim, Sumeyra Alan; Kalpaklioglu, Ayse Fusunbeta-Lactams, particularly penicillins, may cause several allergic reactions. We described symmetric drug-related intertriginous and flexural exanthema (SDRIFE) illness in this case, a rare instance of systemic contact dermatitis caused by amoxicillin/clavulanic acid that needs to be considered in the differential diagnosis. A 65-year-old male patient was admitted to our Allergy Outpatient Clinic because of increased blue-purple pigmentation on the flexural surfaces of the hip, forearm, axilla, and posterior face of the neck. The patient was receiving a combination of angiotensin receptor blocker (ARB) and hydrochlorothiazide diuretic medication for hypertension. The patient used an antibiotic containing amoxicillin three months ago; As a result, there was localized redness, itching, and black spotting without any systemic symptoms. Similarly, the patient reported that when he used amoxicillin for an upper respiratory tract infection eight months ago, he experienced similar side effects within 20 days and recovered when he applied corticosteroid ointment.Due to the symmetrical site involvement following the consumption of penicillin group antibiotics with a five-month gap and subsequent comparable reactions in our patient, SDRIFE was taken into consideration. The results of the skin punch biopsy identified Baboon Syndrome (SDRIFE). Treatment with topical corticosteroids and antihistamines began. Clinically speaking, SDRIFE is distinguished by significant erythema of the gluteal/perianal area and/or V-shaped erythema of the inguinal/perigenital area, symmetric involvement of at least one other intertriginous or flexural area, and the absence of systemic signs or symptoms. The possibility that the medication may have contributed to the patient's erythematous eruption in the flexural regions should be taken into account, and the patient should be advised to stop taking the medication and not use it again.Öğe Anaphylaxis After Consumption of Guar Gum-Containing Food: A Report of Two Cases(Springernature, 2022) Dumanoglu, Betul; Alpagat, Gulistan; Poyraz, Merve; Yalim, Sumeyra Alan; Baccioglu, AyseGuar gum is a food additive that acts as a thickening agent. Although the relationship between guar gum and occupational rhinitis/asthma has already been established, only very few cases of anaphylaxis were associated with guar gum ingestion. We present two examples of anaphylaxis induced by guar gum. Both cases were successfully treated with adrenaline. Moreover, serum-specific immunoglobulin E (IgE) with the culprit agent was detected in blood samples. To the best of our knowledge, here we present the first case of class 6 guar gum-specific IgE-positive anaphylaxis. This report aims to raise awareness of rare food additive allergies such as guar gum.Öğe Asthma as a Comorbid Disease in COVID-19(BILIMSEL TIP YAYINEVI, 2020) Baccioglu, Ayse; Bavbek, SevimSevere acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a novel coronavirus that causes coronavirus disease 2019 (COVID-19). In terms of asthma and COVID-19, there is also a risk of experiencing an asthma exacerbation triggered by coronavirus infection beyond the direct risk of the infection itself. As a comorbid disease, the prevalence of COVID-19 infection in asthma patients is not clear. In addition, the influence of asthma on the severity of COVID-19 has not been reported. The aim of this review was to summarize the reported worldwide data about the prevalence and the clinical characteristics of patients with asthma during COVID-19 infection.Öğe Change in Allergy Practice during the COVID-19 Pandemic(Karger, 2021) Ozturk, Ayse Bilge; Baccioglu, Ayse; Soyer, Ozge; Civelek, Ersoy; Sekerel, Bulent Enis; Bavbek, SevimBackground: International guidelines in asthma and allergy has been updated for COVID-19 pandemic and pandemic has caused dramatic changes in allergy and immunology services. However, it is not known whether specialty-specific recommendations for COVID-19 are followed by allergists. Objectives: By conducting this study, we aimed to determine the attitudes and experiences of adult/pediatric allergists on allergy management during COVID-19. Method: We used a 20-question survey to elicit data from allergists (residents and pediatric and adult allergists registered to the Turkish National Society of Allergy and Clinical Immunology) across Turkey via e-mail. We analyzed the data statistically for frequency distributions and descriptive analysis. Results: A total of 183 allergists participated in the survey. Telemedicine was used for management of asthma (73%), allergic rhinitis (53%), atopic dermatitis (51%), chronic urticaria/angioedema (59%), drug hypersensitivity (45%), food allergy (48%), venom allergy (30%), anaphylaxis (22%), and hereditary angioedema (28%). Thirty-one percent of the respondents discontinued subcutaneous immunotherapy (SCIT) during the COVID-19 pandemic. Thirty-four percent of the physicians reported interruption of systemic steroid use in asthma patients, and 25% of the respondents discontinued biological therapy. Conclusions: Allergists in Turkey have been using telemedicine at a high rate during the COVID-19 pandemic for asthma and rhinitis. The continuation rate of SCIT was low while the discontinuation rate of biologicals and systemic steroid use in asthma was high in Turkey.Our study results and learning from the experiences of other countries and specialties may help to optimize allergy practice and compatibility with international guidelines. (C) 2020 S. Karger AG, BaselÖğe Characteristics of asthma in an older adult population according to sex and control level: why are asthma symptoms in older women not well-controlled?(Taylor & Francis Ltd, 2024) Karadogan, Dilek; Yilmazel Ucar, Elif; Yavuz, Yasemin; Baccioglu, Ayse; Ozturk, Ayse Bilge; Bozkurt, Nurgul; Kavas, MuratObjectiveThe older adult population in Turkey has increased by 22.6% in the last 5 years, and the characteristics of such patients with asthma remain uninvestigated. Therefore, we aimed to evaluate the characteristics of older adults with asthma according to sex and asthma control status to provide an in-depth overview of asthma in this population in Turkey.MethodsThe data of older adults (age 65 years and over) with asthma were obtained from a multicenter, cross-sectional asthma database registry (Turkish Adult Asthma Registry, TAAR) funded by the Turkish Thoracic Society. Comparisons were made based on sex and asthma control levels using the Global Initiative for Asthma (GINA) Asthma Symptom Control Questionnaire.ResultsOf the 2053 (11.5%) patients registered with the TAAR, 227 were older adults (median age, 69 (8), women, 75.8% (n = 172)). Of these, 46.5% (n = 101) had obesity to some degree. Compared with men, women had lower education, income levels, and employment rates. Additionally, women exhibited a higher prevalence of obesity, hypertension, and thyroid gland disease than men. Being female (OR: 2.99; 95% CI: 1.307-6.880), the presence of gastroesophageal reflux disease (OR: 2.855; 95% CI: 1.330-6.130), and a predicted forced expiratory volume in the first-second value lower than 80% (OR: 2.938; 95% CI: 1.451-5.948) were associated with poorly controlled asthma.ConclusionsHerein, older adults comprised 11.5% of adult patients with asthma. Being female poses a disadvantage in terms of both asthma prevalence and control in the older adult asthmatic population owing to the prevalence of comorbidities and socioeconomic sex-related distinguishing factors.Öğe Does Serum Leptin Differ Between Patients With Rhinitis Of Allergic Vs Nonallergic Aetiology?(Mosby-Elsevier, 2014) Kalpaklioglu, Ayse Fusun; Baccioglu, Ayse…Öğe Does serum leptin levels differ between patients with rhinitis of allergic versus nonallergic aetiology?(Wiley, 2021) Kalpaklioglu, Ayse Fusun; Baccioglu, Ayse; Yalim, Sumeyra AlanBackground Leptin may play a critical role in airway inflammation. However, it has rarely been evaluated in rhinitis with different aetiology. This study aimed to compare the serum leptin levels between allergic rhinitis (AR) and nonallergic rhinitis (NAR). Methods Patients with chronic rhinitis were classified due to skin prick (ALK-Abello/Madrid) and/or serum-specific immunoglobulin E tests (UniCAP 100-Pharmacia), against to aeroallergens if concordant with symptoms. Results A total of 398 patients with a mean age of 29.03 years were recruited and grouped as AR and NAR. Mean serum leptin levels were similar in patients with NAR and AR, as well as in patients with and without asthma, but were significantly higher in females than males in both groups. Also, leptin levels were significantly higher in obese than nonobese patients in AR. In correlation analysis, leptin levels were found to be correlated with female gender, older age, and high body mass index (BMI) in the whole group. Despite the higher total nasal symptom score (TNSS) in patients with AR compared with NAR, there was no association of leptin levels with TNSS, severity and seasonality of symptoms, and allergen sensitization. In logistic regression analysis, younger age and high serum leptin levels were found to be independent predictors for the diagnosis of AR. Conclusions We conclude that female patients with high BMI are more prone to AR probably due to immunological effects of adipose tissue, in addition to hormonal factors. This study showed that leptin measurement has limited value as a sole diagnostic tool to differentiate AR and NAR.Öğe Erythema Multiforme-like Dermatitis Due to Isoniazid Hypersensitivity in a Patient With Psoriasis(Quadrant Healthcom Inc, 2021) Baccioglu, Ayse; Karabulut, Ayse Anil; Kalpaklioglu, Ayse Fusun[Abstract No tAvailable]Öğe Evaluation of Knowledge About Anaphylaxis in Dentistry and Medical Faculty Students; Need for More Training(Bilimsel Tip Yayinevi, 2021) Baccioglu, Ayse; Kalpaklioglu, Ayse Fusun; Cimsir, DilekObjective: Anaphylaxis is a serious reaction that needs rapid intervention. However, some healthcare professionals may have inadequate knowledge about anaphylaxis to manage this situation. The aim of this study was to evaluate the level of knowledge about anaphylaxis in dentistry students (DS) in comparison with medical school ones (MS). Materials and Methods: Students were recruited from the Dentistry (n=81) and Medical (n=144) Faculties of the University Hospital. The level of knowledge about anaphylaxis was evaluated by using a questionnaire with 26 items that was used previously. Results: The overall response rate was 89.9%. One tenth of the study group had ever encountered a case with anaphylaxis, but 2.8% of them stated that they had involved in the treatment by themselves. Almost all of the participants stated that allergy might be a life-threatening reaction. Additionally, 43.3% reported that they had epinephrine in their department. DS knew less than MS about the primary use of epinephrine after assessing the airway, breathing and circulation in the treatment of anaphylaxis, and even in suspicious cases (59.3% vs. 98.6%, and 42% vs. 94.4%, all p<0.001). DS had significantly less knowledge about anaphylaxis treatment and epinephrine application than medical ones (all p <0.001). Furthermore, the information of that the minimum duration for readministration of epinephrine as 10 minutes was known by the half of MS, and one fourth of DS (p<0.001). The appropriate follow-up duration of patients with anaphylaxis was unknown in half of DS, and one fifth of MS (p<0.001). Even though MS had a higher rate of knowledge about the responsible and closest department dealing with anaphylaxis than dental students (p=0.02), DS were more aware of referring the patient with anaphylaxis to an allergy clinic (77.8% vs. 62.9%, p<0.001). Almost all MS had heard about the epinephrine auto-injector, in contrast to one third of the DS (p<0.001). Most of the participants, but mainly the MS knew that anaphylaxis could be diagnosed clinically. The case questions about diagnosis of anaphylaxis related to local anesthetic and beta-lactam antibiotic use were answered correctly in a higher rate in MS than DS (p=0.01 and p<0.001), whereas the rate of correct diagnosis of anaphylaxis following a bee sting was similar between the groups. Conclusion: This study showed the gaps about the diagnosis and management of anaphylaxis not only in MS, but also in dentistry ones. It is possible to encounter a case of anaphylaxis for every student during clinical practice in the future. Thus, education about anaphylaxis should be included in the national dentistry core education programme and be improved in the medical school as well.Öğe Evaluation of systemic inflammation markers in patients with rhinitis(Springer Heidelberg, 2024) Yalim, Suemeyra Alan; Kalpaklioglu, Ayse Fuesun; Baccioglu, Ayse; Poyraz, Merve; Alpagat, Gulistan; Dumanoglu, BetulBackground: Rhinitis affects the majority of the population. It may generate localized nasal mucosal inflammation via allergic (AR) or nonallergic (NAR) processes, but it is unknown if this might also result in systemic inflammation, which can raise morbidity and death. Using current serum inflammatory markers, we sought to investigate systemic inflammation in patients with chronic rhinitis. Methods: In this retrospective case-control study, we included 439 patients with newly diagnosed AR (n = 179), NAR (n = 157), and 103 healthy individuals. Inflammation-related blood parameters were collected as lymphocyte/monocyte ratio (LMR), neutrophil/lymphocyte ratio (NLR), eosinophil/neutrophil ratio (ELR), and systemic immune inflammation index (SII). Results: All groups were similar in terms of age, gender, and body mass index. Neutrophil counts were significantly higher both in AR and NAR groups compared to controls (4.51 +/- 0.09, 4.54 +/- 0.1 vs. 3.73 +/- 0.1, p < 0.001). NLR (1.91 +/- 0.56, 1.89 +/- 0.61, 1.61 +/- 0.59, p < 0.001), LMR (5.76 +/- 0.17, 5.93 +/- 0.17, 5.1 +/- 0.15, p = 0.005), ELR (0.1335 +/- 0.007, 0.0999 +/- 0.006, 0.12 +/- 0.009, p = 0.003), SII (533.3 +/- 16.6, 558.1 +/- 20.9, 479.9 +/- 22.2, p = 0.035), and CRP (1.44 +/- 0.09, 1.67 +/- 0.09, 0.87 +/- 0.04, p < 0.001) were significantly higher in AR and NAR groups than the controls, respectively. SII (r = 0.146, p = 0.007) and ELR (r = 0.254, p < 0.001) were correlated with the presence of asthma. Conclusion: We found that systemic circulation of inflammatory cells was significantly increased in rhinitis with/without allergy compared to the control group. This study showed that not only AR, but also NAR triggers a systemic increase of inflammation which supports the link between rhinitis and comorbid conditions such as asthma. Therefore, effective treatment may be suggested for local inflammation and its systemic manifestations.Öğe False-positive PET-CT scan secondary to interstitial pneumonitis mimicking malignancy in fire eater's lung(European Respiratory Soc Journals Ltd, 2018) Baccioglu, Ayse; Eraslan, Dilek; Halici, Sule; Kalpaklioglu, FusunInhalation of flammable oily hydrocarbons may cause interstitial pneumonitis by diffusion throughout the bronchial mucosa and alveoli. A 70 year old male was admitted with progressive dyspnoea, fever, haemoptysis, cough, and sputum for 6 weeks. Physical examination revealed fine crackles on the right side of thorax, and O2 sat: 94%. He had performed fire-eating show 6 weeks ago. Chest x-ray showed irregular opacity on the right lower zone. Thorax computed tomography (CT) was reported a mass (12x11mm) located in the medial and right lower lobe, surrounded the middle lobe bronchus and pulmonary vein, invades to the hilar area, and diaphragm, and surrounded with multiple nodules. Parenteral antibiotic was given since he had leucocytosis, elevated procalsitonin, and sedimentation (111/hr). After 4 weeks, positron emission tomography (PET)-CT was resulted as right hilar lymphadenopathy (19x22mm, SUV: 5), and mass (53x77mm, SUV: 8.7) with satellite nodules and ground glass opacity. Diagnostic bronchoscopy revealed erythema and narrowing of the entrance of medial lobe. Bronchial lavage (BL), and bronchial mucosa biopsy was negative for any pathogens, and malignancy. Transthoracic needle lung biopsy was consistent with “interstitial pneumonitis”. Oral corticosteroid was started as 1mg/kg/day, and gradually tapered in 3 months. Finally, his clinical findings were improved, as well as radiologic abnormalities. This case illustrates the importance of considering interstitial pneumonitis in fire eaters even some findings are incompliant such as false-posivitiy in PET-CT, and no demonstration of lipid laden macrophages in BL.Öğe Hypereosinophilia of undetermined significance in a rheumatoid arthritis patient(Wiley, 2022) Dumanoglu, Betul; Alpagat, Gulistan; Poyraz, Merve; Baccioglu, Ayse; Kalpaklioglu, Ayse Fusun[Abstract No tAvailable]Öğe Physicians' preference for controller medication in mild persistent asthma(W B Saunders Co Ltd, 2017) Bakirtas, Arzu; Kutlu, Ali; Baccioglu, Ayse; Erkekol, Ferda Oner; Bavbek, Sevim; Kalayci, OmerBackground: Although the asthma guidelines recommend inhaled corticosteroids(ICS) or leukotriene receptor antagonists-(LTRAs) for the treatment of mild persistent asthma, factors governing the physicians' preference are unknown. We aimed to investigate the preference of physicians for the controller medication and the factors governing their choice. Methods: A self-administered questionnaire composed of 16 questions that aimed to determine the preference of the physicians for the first choice controller medication in mild persistent asthma and physician and patient related factors that may be associated with this selection was e-mailed to the members of the Turkish National Society of Allergy and Clinical Immunology and distributed to participants in the 21st congress. Results: Of the 670 questionnaires, there were 51% participants and 336 of them were complete enough to be included in the analysis. Low dose ICS was preferred as the first choice controller medication for mild persistent asthma by 84.5% of the physicians. The reasons for physicians' preference were different for ICS and LTRA. In the logistic regression analysis, use of asthma guidelines (OR:3.5, 95%Cl:1.3-9.3, p = 0.01), alignment in guidelines (OR:2.9, 95%Cl:1.4-5.8, p = 0.002) and the opinion that it is a more effective (OR:2.3, 95%Cl:1.1-4.8, p = 0.02) were independently associated with ICS preference. Being a pediatrician (OR:5.4, 95%Cl: 2.7-10.5, p < 0.001) and the opinion that it has better patient compliance (OR:4.4, 95%CI: 1.6-12.0, p = 0.004) were independently associated with LTRA preference. Conclusion: Surveyed Turkish physicians, the majority of whom were specialists, preferred ICS over LTRA as controller medication in mild persistent asthma. Asthma guidelines, training background (pediatrician versus not) and perceived efficacy and patient compliance appeared to influence their preferences. (C) 2017 Published by Elsevier Ltd.Öğe Pros and Cons of Nebulizer Treatment in Asthma Exacerbation During the COVID-19 Pandemic(Bilimsel Tip Yayinevi, 2021) Ozturk, Ayse Bilge; Baccioglu, Ayse; Uysal Soyer, Ozge; Civelek, Ersoy; Sekerel, Bulent Enis; Bavbek, SevimNebulizers generate aerosols and may potentially transmit respiratory viral particles including SARS-CoV-2. There is a great concern about the use of a nebulizer in the treatment of asthma exacerbations in the hospital or home setting during the COVID-19 pandemic and its use is not recommended unless essential. However, aerosol therapy should not be avoided in obligatory indications. Therefore, indications of nebulizer use during the pandemic should be evaluated on an individual basis in case of a severe asthma attack, and infection control recommendations should be followed by clinicians while using nebulizers. In this article, we aimed to assess the safety in addition to the pro and con sides of nebulizer treatment in asthma exacerbation during the COVID-19 pandemic.Öğe Rationale for the autologous serum skin test in acute versus chronic urticaria(Termedia Publishing House Ltd, 2019) Demirkan, Serkan; Baccioglu, AyseIntroduction: Autologous serum skin test (ASST) is a rapid, in-vivo clinical test to detect functional autoantibodies in patients with chronic spontaneous urticaria (CSU), but the rationale for its use in acute urticaria (AU) is unknown. Aim: To evaluate the efficacy of ASST among patients with AU or CSU. Material and methods: Treatment-naIve adult (age >= 18 years) patients with a diagnosis of AU (< 6 weeks' duration) and CSU were enrolled prospectively in a cross-sectional study. Healthy age- and sex-matched subjects served as controls. Besides a detailed history and physical examination, ASST, total immunoglobulin E (IgE), freeT3 (fT3), freeT4 (fT4), anti-thyroglobulin, and anti-TPO levels were assessed in all subjects. Results: Of 101 subjects, mean age was 34.35 +/- 12.68 years and the study comprised 58.4% of females with no difference between AU (n = 27), CSU (n = 46), and control groups (n = 28). The ratio of positivity in ASST was similar between AU (25.9%) and CSU groups (21.7%), but higher than in controls (10.7%, p = 0.33 for all). The ratio of patients with high total IgE levels (> 100 IU/ml) in AU (85.2%) and CSU (65.2%) groups was similar (p = 0.06), but significantly higher than in the control group (10.7%) (p < 0.001 and p < 0.001). The CSU group had significantly higher abnormal thyroid test results (45.7%) than AU (14.8%) and control groups (3.6%) (p = 0.01 and p < 0.001), whereas patients with clinically diagnosed thyroiditis were only in the CSU group (6.5%). In logistic regression analysis, there was no relation found among the possible risk factors for ASST, even if analysed separately as AU, CSU and control groups. Conclusions: Even though thyroid function test levels were found to be related with CSU, and total IgE was associated with urticaria, ASST was found to be of importance. This study confirms that ASST was insufficient to demonstrate autoimmunity and acute-chronic urticaria nature. Further tests indicating auto-antibodies in AU and CSU are needed.Öğe Starting as cold-induced anaphylaxis but following as urticaria(Wiley, 2022) Poyraz, Merve; Alpagat, Gulistan; Dumanoglu, Betul; Yalim, Sumeyra Alan; Baccioglu, Ayse; Kalpaklioglu, Ayse Fusun[Abstract No tAvailable]
