Öğe Accelerated atherosclerosis in patients with common variable immunodeficiency: Is it overlooked or absent?(Churchill Livingstone, 2015) Ucar, Ramazan; Arslan, Sevket; Turkmen, Kultigin; Caliskaner, Ahmet ZaferCommon variable immunodeficiency (CVID) is a heterogeneous primary deficiency characterized by hypogammaglobulinemia, recurrent infections, and an increased risk of autoimmune disease and malignancy, and so chronic inflammation. Cardiovascular disease is the leading cause of mortality in the general population. Recent studies have suggested that chronic inflammation is an important player in the pathogenesis of CVID. Accelerated atherosclerosis due to ongoing inflammation from recurrent infections and autoimmunity is an expected clinical entity in patients with CVID. However, cardiovascular mortality as a cause of death in CVID series is either absent or minor. We hypothesized that accelerated atherosclerosis and cardiovascular disease are overlooked by clinicians, or atherosclerosis is really lower than that in the general population that may be prevented by some factors such as life-long immunoglobulin replacement treatment.

The aim of this study was to determine the prevalence, and clinical and laboratory characteristics of various allergic diseases in patients with CVID. Methods: The study included patients aged & GE;18 years who were followed up for a diagnosis of CVID. Patients were separated into 5 groups according to the clinical phenotypic characteristics of lymphoproliferation, autoimmunity, gastrointestinal diseases, allergic diseases, and malignancy. Atopic dermatitis (AD), drug hypersensitivity reaction (DHR), allergic rhinitis (AR), and asthma were accepted as allergic diseases. Results: The most commonly seen clinical phenotypes were lymphoproliferation in 41 (48.8%) patients and allergic diseases in 31 (37%). AD was determined in 2 (2.4%) patient, DHR in 5 (6%), AR in 7 (8.3%), and asthma in 21 (25%). The delay in diagnosis of patients with allergic disease was determined to be shorter compared to those without allergic disease (p = 0.042). Serum total immunoglobulin E level, CD19(+) B cell, switched memory B cell, and natural killer cell counts were determined to be higher in the CVID patients with allergic disease compared to those without (p = 0.007, p = 0.022, p = 0.023, p = 0.017, respectively). Conclusion: Allergic diseases should be considered as a marker of clinical phenotype in CVID because of the clinical and immunological differences. Early diagnosis and treatment of allergic diseases in patients with CVID can improve quality of life.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 Anaphylaxis in older adult patients: a 10-year retrospective experience(Elsevier, 2022) Yildiz, Eray; Arslan, Sevket; Coelkesen, Fatih; Evcen, Recep; Aykan, Filiz Sadi; Kilinc, MehmetBackground: Despite the worldwide increase in life expectancy and the elderly population, very little is known about the characteristics of anaphylaxis in older adults.Methods: A retrospective scan was made of the files of patients who presented at the Allergy Unit of our clinic between October 2011 and October 2021. The study included 971 patients aged >18 years who met the criteria for diagnosis of anaphylaxis. The patients were separated into 2 groups of adults (18-64 years) and older adults (>65 years).Results: The adult group included 887 (91.3%) patients and the older adult group, 84 (8.7%) patients. Comorbid diseases were seen more frequently in the older adults than in the adult group (p < 0.001). Drugs were seen to be the most common trigger of anaphylaxis in both groups, and this was more common in the older adult group (p = 0.039). Food was a more common trigger of anaphylaxis in the adult group than in the older adult group (p = 0.017). In both groups, the skin was the organ most affected, and was less affected in the older adults than in the adults (p = 0.020). Cardiovascular symptoms were seen significantly more and respiratory symptoms significantly less in the older adult group (p < 0.001, p = 0.002, respectively). Admission to the hospital and the intensive care unit was more frequent in the older adult group and rates of adrenalin administration were higher compared to the adult group (p < 0.001 for all).Conclusion: Anaphylaxis in the older adults is generally caused by drugs. Older adults were found to have more cardiovascular symptoms and more frequent adrenalin injections, hospitalizations and intensive care unit admissions.Öğe An association between immune status and chest CT scores in COVID-19 patients(Wiley, 2021) Colkesen, Fatih; Poyraz, Necdet; Arslan, Sevket; Yilmaz, Pinar Diydem; Kurt, Esma Kepenek; Korkmaz, Celalettin; Yildiz, ErayBackground The characteristic features of the immune responses of COVID-19 patients and how they reflect lung involvement have not been clearly elucidated. Aim The aim of this study was to examine the immune status and the correlations thereof with chest CT scores and lung involvement of patients with COVID-19. Methods In this retrospective and single-center study, 72 patients with laboratory-confirmed COVID-19 were recruited. The counts of peripheral lymphocyte subsets (CD3(+) T cells, CD4(+) T cells, CD8(+) T cells, CD19(+) B cells and CD16(+) 56(+) NK cells) and those of serum immunoglobulins (IgA, IgG, IgM) were measured and their associations with chest CT scores analysed. Results The proportions of lymphopenia in patients with extensive lung involvement were twice that in the general study population. In the severe disease group, the levels of total lymphocytes, T cells, B cells, NK cells; and serum IgA levels, were significantly lower than in the mild disease group (all P < .05). We found that the numbers of lymphocyte subsets and the IgA level negatively correlated with the chest CT scores. On multivariate regression analysis, pretreatment decreases in total lymphocytes, CD3(+) T cells, CD4(+) T cells, and CD19(+) B cells, and serum IgA levels, were independent predictors of severe lung involvement. Conclusions The cell numbers of peripheral lymphocyte subsets and the serum IgA level were negatively correlated with the chest CT scores in COVID-19 patients. These parameters tended to independently predict severe lung involvement in such patients.Öğe Cetuximab Induced Acneiform Eruption, Telangiectasia, Hypertrichosis, Paronychia, and Digital Fissures: a Case Report(Galenos Yayincilik, 2019) Unal, Mehmet; Unal, Gulbahar Urun; Arslan, Sevket; Tol, Huseyin; Balevi, SukruEpidermal growth factor plays a critical role in tumor growth and progression, including cell proliferation, inhibition of apoptosis, angiogenesis, invasion, and metastasis. Cetuximab is the first monoclonal antibody that effects by binding to epidermal growth factors in the treatment of metastatic colorectal cancer. Because of the increasingly frequent use of epidermal growth factors inhibitors such as cetuximab in oncology services, perhaps more patients with the dermatologic complaints may require evaluation by dermatologists. Here, we report a case of severe acneiform eruption, hypertrichosis, telangiectasia, paronychia, ingrown toenails, pyogenic granuloma-like lesions, and digital fissures due to cetuximab in a 53-year-old female patient with colorectal cancer with metastases.Öğe Common Variable Immunodeficiency and Pulmonary Amyloidosis: A Case Report(Springer/Plenum Publishers, 2015) Arslan, Sevket; Ucar, Ramazan; Yavsan, Dudu Mehmet; Esen, Hasan; Maden, Emin; Reisli, Ismail; Caliskaner, Ahmet ZaferCommon variable immunodeficiency is the most common symptomatic primary immune deficiency characterized by hypogammaglobulinemia, recurrent infections, and increased risk of autoimmune disease and malignancy. Secondary amyloidosis develops from chronic inflammatory conditions. The co-existence of CVID (especially in patients with bronchiectasis) and secondary amyloidosis has been reported rarely. We describe the first case of pulmonary hypertension secondary to pulmonary amyloidosis in a patient with CVID.Öğe Comparision of the Characteristics of Familial and Sporadic Cases in Patients with Gastric Cancer(Modestum Ltd, 2015) Arslan, Sevket; Ilhan, MahmutIn this study, it was aimed to find the percentage of the non-familial and familial cases and comparison of their characteristic susing 2004 Canadian criteria in our cancer patients. The data from the files of 200 patients with histopathologically proven gastric cancer registered in our Medical Oncology Clinic were evaluated between January 2001 and December 2005. In our study, the ratio of familial cases is 10%. The mean ages of the patients are 56.44 +/- 0.78 in non-familial group and 53.30 +/- 2.90 in familial group. There were 113 males (62.77%), 67 females (37.23%) in non-familial group and 14 males (70%), 6 females (30%) in familial group. Histological types in familial and non-familial groups are; intestinal type 23.8% (n:3) and 75.23% (n:82); diffuse type 76.92% (n:10) and 24.77% (n:27) (p<0.01), respectively. The rate of cancers in localized stages are 5% (n:1) and 26,67% (n:48); where as the rates of advanced-stage cancers were 95% (n:19) and 73.33% (n:132) (p<0.01) in familial and non-familial groups respectively. Non-familial patients were 9.38% (n:12) Hp negative and 90.62% (n:116) were Hp positive where as familial cases were 100% (n:13) Hp positive (p<0.01). Blood groups in familial and non-familial groups are; Group A were 33.33% (n=2) and 58.46% (n:38); group B were 16.67% (n:1) and 10.77% (n:7), group O were 50% (n:3) and 29.23% (n:19) respectively. One patient (1.54%) in non-familial group was AB positive. Endoscopic screening should strongly be suggested in cases of unexplained upper abdominal complaints, especially for those people living in rural area in Van region.Öğe Comparision of the Characteristics of Familial and Sporadic Cases in Patients with Gastric Cancer(Modestum Ltd, 2015) Arslan, Sevket; Ilhan, MahmutIn this study, it was aimed to find the percentage of the non-familial and familial cases and comparison of their characteristic susing 2004 Canadian criteria in our cancer patients.

A suspected diagnosis is based on clinical symptoms, a plausible contact to allergens and a suitable history of dermatitis. Therefore, careful diagnosis by patch testing is of great importance because the patch testing is important to find out which allergen/material causes the complaints. Metallic allergens such as cobalt are among the most common causes of allergic contact dermatitis, but frequencies of contact dermatitis to these allergens may vary in different skin areas. Here, we report an unusual case of cobalt allergy on the skin contact with the prosthetic leg of a 30-year-old female patient. Case description and methods: The patient developed maculopapular and vesicular lesions on her contact region of residual limb to prosthetic leg. Findings and outcome: She underwent standard patch testing, which resulted in a strong positive reaction to cobalt chloride. Conclusion: This case report may serve to remind doctors to be aware of potential allergic reactions to prostheses and to enable them to recognize a metal allergy if it appears. Prosthetists should also be reminded of potential allergic reactions. Clinical relevance Cobalt can be used as an accelerator in making a prosthetic socket. Several cases have been reported concerning allergies to components of the prosthetic socket. This is the first report of sensitization to cobalt which is used in making a prosthetic leg.Öğe Could aluminum be a new hidden allergen in type 1 hypersensitivity reactions when used as a drug additive?(Termedia Publishing House Ltd, 2016) Kutlu, Ali; Ucar, Ramazan; Aydin, Ersin; Arslan, Sevket; Caliskaner, Ahmet Zafer[Abstract Not Availabe]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 Evaluation of the Effectiveness of the 6 Warning Signs of the European Society for Immunodeficiencies for Primary Immunodeficiencies in Older Adults(Karger, 2024) Yildiz, Eray; Colkesen, Fatih; Evcen, Recep; Aykan, Filiz Sadi; Kilinc, Mehmet; Arslan, SevketIntroduction: Diagnostic delay in cases of primary immunodeficiency (PID) is a significant problem for clinicians, and most do not have sufficient awareness of this uncommon disorder. The European Society for Immunodeficiencies (ESID) has developed 6 warning signs to increase awareness of adult PIDs. The aim of this study was to determine the prevalence of PID in older adults regardless of the reason for presentation and to evaluate the effectiveness of the 6 warning signs of ESID in the diagnosis of PIDs. Methods: The study included 1,331 patients aged >= 65 years who presented at our clinic for any reason and were questioned about the ESID 6 warning signs for PIDs. After the exclusion of reasons for secondary immunodeficiency (SID), all the patients underwent immunological evaluation for the diagnosis of potential underlying PIDs. Results: After excluding 6 patients diagnosed with SID, PID was diagnosed in 16 (1.2%) of 1,325 older adults using ESID warning signs. The most common reasons for presentation were infection (69%) in the PID group and urticaria and/or angioedema (41.5%) in the non-PID group. The most common PID subgroup was common variable immunodeficiency (50%). In 12 of the patients diagnosed with PID, there was at least 1 positive ESID warning sign. In 4 patients, PID was determined despite negative ESID warning signs. The patients diagnosed with PID showed a significant, minimal level of agreement with questions 1 and 4 of the ESID warning signs (p < 0.001, kappa = 0.204, p = 0.005, kappa = 0.208, respectively). Conclusion: The ESID warning signs do not encompass all the symptoms and findings of PIDs. There is a need for more infection-centered questions to determine PIDs in older adults. Therefore, the ESID warning signs should be further developed.Öğe Health-related quality of life, depression and mortality in peritoneal dialysis patients in Turkey: seven-year experience of a center(Informa Healthcare, 2014) Turkmen, Kultigin; Guney, Ibrahim; Yazici, Raziye; Arslan, Sevket; Altintepe, Lutfullah; Yeksan, MehdiIntroduction: Impairment of health-related quality of life (HRQoL) and being in a depressive mood were found to be associated with increased mortality in peritoneal dialysis (PD) patients. We aimed to investigate the association between HRQoL, depression, other factors and mortality in PD patients. Materials and methods: Totally 171 PD patients were included and followed for 7 years in this prospective study. Results: Of 171 PD patients, 45 (26.3%) deceased, 18 (10.5%) maintained on PD, 87 (50.9%) shifted to hemodialysis (HD) and 21 (12.3%) underwent transplantation. The most common cause of death was cardiovascular disease (32, 71.1%) followed by infection (6, 13.3%), cerebrovascular accident (5, 11.2%). The etiology of patients who shifted to HD was PD failure (41, 47.1%), peritonitis (33, 37.9%), leakage (6, 6.9%), catheter dysfunction (3, 3.4%), self willingness (4, 4.6%). Non-survivors were older than survivors (56.6 +/- 15.0 vs. 43.6 +/- 14.6, p = 0.003). There were also statistically significant difference in terms of albumin, residual urine, presence of diabetes and co-morbidity. When the groups were compared regarding HRQoL scores, non-survivors had lower physical functioning (p<0.001), role-physical (p = 0.0045), general health (p = 0.004), role-emotional (p = 0.011), physical component scale (PCS) (p = 0.004), mental component scale (MCS) (p = 0.029). Age, presence of residual urine, diabetes, albumin, PCS and MCS were entered in regression analysis. Decrease of 1 g/dL of albumin and being diabetic were found to be the independent predictors of mortality. Conclusions: Diabetes and hypoalbuminemia but not HRQOL scores were associated with higher mortality in PD patients after 7 years of following period.Öğe How effective are the 6 European Society of Immunodeficiency warning signs for primary immunodeficiency disease?(Elsevier Science Inc, 2016) Arslan, Sevket; Ucar, Ramazan; Caliskaner, Ahmet Zafer; Reisli, Ismail; Guner, Sukru Nail; Sayar, Esra Hazar; Baloglu, IsmailBackground: The European Society of Immunodeficiency (ESID) developed 6 warning signs to promote the awareness of adult primary immunodeficiency disease (PID). Objective: To screen adult patients for the presence of PID using these 6 warning signs to determine the effectiveness of this protocol. Methods: Questions related to the ESID warning signs for adult PID were added to the standard outpatient clinic file system and asked of 3,510 patients who were admitted to our clinic for any reason. Patients with signs and/or suspicion of PID based on their medical history underwent immunologic investigation. Results: In total, 24 patients were diagnosed as having a PID. The most common reason that patients with PID were admitted was frequent infection (n = 18 [75%]), and the most common PID subgroup was common variable immunodeficiency (n = 12 [50%]). Twenty patients with PID had at least one positive finding according to the ESID warning signs. Two patients with gastrointestinal concerns and 2 with dermatologic symptoms were also diagnosed as having a PID, although they did not have any of the ESID warning signs. Conclusion: The ESID warning signs do not specify the need for symptoms to diagnose a PIDs and do not include a comprehensive list of all signs and symptoms of PIDs. As a result, more than infection-centric questions are needed to identify adult patients with immunodeficiencies. (C) 2016 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc.

Many adverse reactions to metamizole, such as early or late-onset systemic reactions and bone marrow suppression, have been identified. In this report, we present a case of systemic reaction after the application of parenteral metamizole (Novalgin (R) ampoule; Sanofi Aventis, Istanbul, Turkey) and discuss the mechanism underlying the reaction.Öğe The importance of determining the triggering antigen in asthma and anaphylaxis: a case with soy allergy(Bilimsel Tip Yayinevi, 2013) Arslan, Sevket; Caliskaner, ZaferTry to identify and eliminate the causative allergen plays an important role in the management of allergic diseases and asthma. It is particularly essential in anaphylaxis which may lead to life-threatening consequences. When evaluating a patient with history of asthma or anaphylaxis, spreading of allergens, routes of allergen exposure and allergen induced clinical symptoms should be review in detail with respect to current literature. In this paper, we report a case with periodic asthma attacks and recurrent anaphylaxis.Öğe Increasing Prevalence of Sensitization to Cat/Dog Allergens in the COVID-19 Pandemic(Karger, 2024) Evcen, Recep; Colkesen, Fatih; Yildiz, Eray; Aykan, Filiz Sadi; Kilinc, Mehmet; Akkus, Fatma Arzu; Arslan, SevketIntroduction: Cat and dog allergens are common indoor triggers for respiratory allergies such as allergic rhinitis and asthma. This study aims to evaluate the prevalence of cat and dog allergies in adults and analyze changes during the COVID-19 pandemic.Methods: We retrospectively analyzed the medical records of 8,102 patients who visited an allergy clinic and underwent skin prick testing (SPT) from March 2018 to March 2022: 2 years before and 2 years during the pandemic. Demographic information, clinical attributes, and laboratory results were examined based on patient records.Results: Of 8,102 SPTs performed, 400 (4.9%) were sensitized to cat allergen and 289 (3.6%) to dog allergen. Allergic rhinitis was the predominant clinical diagnosis in both groups. Of the 400 subjects exposed to cats, 240 (60%) experienced allergic symptoms, while of the 289 subjects exposed to dogs, 65 (22.5%) experienced allergic symptoms during exposure. Within the cat-sensitized group, anaphylaxis was observed in 5 patients (1.3%), while no cases of anaphylaxis were reported in the dog-sensitized group. Compared to the pre-pandemic period, patients presenting during the pandemic had higher rates of cat and dog sensitization (5.7% vs. 4.1%; p < 0.05, 5.2% vs. 1.7%; p < 0.05).Conclusion: During the COVID-19 pandemic, there was an increase in cat and dog allergies among adults. Increased exposure to pet antigens, both directly and indirectly, has resulted in more people becoming sensitized to cats or dogs.Öğe Is common variable immunodeficiency a facilitating factor for fixed drug eruptions? Case Report(Wiley, 2020) Yildiz, Eray; Arslan, Sevket; Colkesen, Fatih; Aytekin, Gokhan[Abstract Not Availabe]Öğe Is major depression associated with serum levels of tumor necrosis factor-alpha in patients with rheumatoid arthritis?(Pergamon-Elsevier Science Ltd, 2015) Uguz, Faruk; Kucuk, Adem; Aydogan, Semra; Arslan, Sevket; Kurt, Hatice Guncu; Toker, Aysun; Sahin, MuhammedObjective: This study presents the serum tumor necrosis factor-alpha (TNF-alpha) levels in rheumatoid arthritis (RA) patients with major depression and without any psychiatric disorder. Methods: The study sample included 61 patients with a diagnosis of RA. Major depression and other psychiatric disorders were screened with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Blood sample for the determination of serum TNF-alpha level was obtained before the psychiatric interview. Results: The prevalence rates of any depressive disorder and any anxiety disorder were 40.3% (n = 25) and 22.6% (n = 14), respectively. Fifteen (24.2%) patients had major depression alone, whereas 27 (43.5%) patients were not diagnosed with any psychiatric disorder. We could not determine any significant differences between the patients with major depression alone and patients without any psychiatric diagnosis with regard to the serum levels of TNF-alpha. Conclusions: The existence of major depression in RA patients does not seem to be associated with serum levels of TNF-ce. (C) 2015 Elsevier Inc. All rights reserved.
