The distribution of sensitization to common aeroallergens in patients with rhinitis and asthma in Sanliurfa, Türkiye.

Introduction: Sensitization to common environmental aeroallergens plays a significant role in the pathogenesis and severity of asthma and allergic rhinitis. Knowledge on the sensitization pattern helps allergen avoidance, prediction of the severity of the disease, and use of specific immunotherapy for the most common allergens. The distribution of sensitization to aeroallergens differs in every region of Türkiye. In this study, it was aimed to investigate the allergen sensitization profiles of patients with asthma and rhinitis in Sanliurfa, which is in Southeast Türkiye. Materials and Methods: Patients with rhinitis and asthma who presented to the outpatient clinic of adult immunology and allergy between April 2021- 2022 were retrospectively evaluated. Demographic information (age, sex), rhinitis and asthma duration, location of residence, allergic and non-allergic comorbidities, smoking history and skin prick test results were extracted from medical records. Results: A total of 472 skin prick tests were performed on patients (35.4% males; 64.6% females), with a mean age of 33.8 years, and 120 (25.4%) were negative for skin reaction. The frequency of sensitivity to allergens was: grass (42.6%), cereal mixtures (41.5%), timothy grass (37.9%), cockroach (37.3%), olive tree (35%), house dust mites (Dermatophagoides farinae 27.5%, Dermatophagoides pteronyssinus 20.8%). In patients with only rhinitis (n= 305), the most frequent aeroallergen was pollen (grasses 43.6%; cereal mixtures 43.3%; timothy grass 41.6%; olive pollen 37.4%). In patients with asthma and rhinitis (n= 134), the most frequent aeroallergen was grass (44.8%). In patients with only asthma (n= 33), the most frequent aeroallergens were D. farinae (27.3%) and cockroach (27.3%). Conclusion: The most frequently detected allergens in this study were pollen, cockroach, and house dust mites, respectively. The findings revealed that pollen was the most frequent aeroallergen in subjects with allergic rhinitis with and without asthma. In patients with only asthma, the most frequent aeroallergen was house dust mites.

Picturing asthma in Turkey: results from the Turkish adult asthma registry.

INTRODUCTION: National data on asthma characteristics and the factors associated with uncontrolled asthma seem to be necessary for every country. For this purpose, we developed the Turkish Adult Asthma Registry for patients with asthma aiming to take a snapshot of our patients, thereby assigning the unmet needs and niche areas of intervention. METHODS: Case entries were performed between March 2018 and March 2022. A web-based application was used to record data. Study outcomes were demographic features, disease characteristics, asthma control levels, and phenotypes. RESULTS: The registry included 2053 patients from 36 study centers in Turkey. Female subjects dominated the group (n = 1535, 74.8%). The majority of the patients had allergic (n = 1158, 65.3%) and eosinophilic (n = 1174, 57.2%) asthma. Six hundred nineteen (32.2%) of the patients had obese asthma. Severe asthma existed in 670 (32.6%) patients. Majority of cases were on step 3-5 treatment (n: 1525; 88.1%). Uncontrolled asthma was associated with low educational level, severe asthma attacks in the last year, low FEV1, existence of chronic rhinosinusitis and living in particular regions. CONCLUSION: The picture of this registry showed a dominancy of middle-aged obese women with moderate-to-severe asthma. We also determined particular strategic targets such as low educational level, severe asthma attacks, low FEV1, and chronic rhinosinusitis to decrease uncontrolled asthma in our country. Moreover, some regional strategies may also be needed as uncontrolled asthma is higher in certain regions. We believe that these data will guide authorities to reestablish national asthma programs to improve asthma service delivery.

Can omalizumab be an alternative treatment for non-atopic severe asthma? A real-life experience with omalizumab.

Introduction: Omalizumab, a humanized monoclonal anti-IgE antibody, has largely demonstrated its efficacy in severe allergic asthma. There are limited data about the effectiveness of omalizumab in patients with non-atopic severe persistent asthma. In this study, we aimed to determine the effect of omalizumab in patients with non-atopic severe asthma and compare the data obtained with those in patients with allergic severe asthma. Materials and Methods: This study was an observational, retrospective, tertiary single-center study that assessed and compared the clinical outcome of adult patients with severe asthma (165 atopic and 41 non-atopic) who have been on omalizumab for one year or longer between January 2008 and January 2020. Effectiveness was assessed by considering symptom scores (GINA symptom control score), daily systemic corticosteroids (SCS) dosage, blood eosinophil counts, pulmonary function, and number of severe exacerbations and hospitalizations within the last one year. Result: Omalizumab exhibited significant improvement in the clinical status of non-atopic asthma patients as measured by GINA symptom score [decreased from 3.77 ± 0.63 to 1.36 ± 1.27 (p<0.001)], the number of emergency room visits for asthma [decreased from 11.25 ± 14.69 to 0.25 ± 0.55 (p<0.001)], and the number of hospitalizations [decreased from 1.17 ± 2.87 to 0.14 ± 0.36 (p= 0.036)]. These results were not significantly different from those obtained in allergic asthma patients. FEV1 improved significantly from 2.08 ± 0.86 to 2.14 ± 0.84 (p= 0.041) and oral corticosteroid doses decreased significantly from 1.67 ± 7.49 to 0.46 ± 2.74 (p= 0.015) in the only atopic group. Conclusions: Omalizumab, which is a proven and effective treatment option for allergic asthma, may also be an efficacious alternative option in non-atopic severe asthma.

Fatigue: A forgotten symptom of asthma.

OBJECTIVE: Fatigue is a common symptom frequently reported in many disorders but little is known about the prevalence of fatigue in asthma. The objective of this study was to determine the prevalence of fatigue in asthmatic patients, the effect of fatigue on asthma quality of life and the relationship between fatigue and anxiety/depression MATERIALS AND METHODS: This prospective cross-sectional study was conducted in Uludag University Faculty of Medicine, Department of Immunology and Allergic Diseases outpatient clinic from June 2019 to December 2019. Fatigue was assessed using the Checklist Individual Strength-Fatigue (CIS-Fatigue), psychological distress was assessed using the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) and quality of life were assessed using the Asthma Quality of Life Questionnaire (AQLQ). RESULTS: In the present study, a total of 168 patients are included with an average age of 43.8 ± 4.3 years. Nearly 64.8% of patients had controlled asthma and (35.2%) patients had uncontrolled asthma. Fatigue (CIS-Fatigue ≥ 27 points) was detected in 62.6% of patients and associated with asthma-related quality of life, asthma control, dyspnea, depression and anxiety (P < 0.05). However, the degree of lung function impairment and asthma severity were not associated with fatigue. CONCLUSIONS: Fatigue as a symptom is common in asthmatic patients and correlates with asthma-related quality of life, asthma control, dyspnea, depression and anxiety. Future studies are needed to better understand the physical, psychological, behavioural and systemic factors that precipitate or perpetuate fatigue in asthma.

Trends of sensitization to aeroallergens in patients with allergic rhinitis and asthma in the city of Bursa, South Marmara Sea Region of Turkey

Background/aim: Allergic rhinitis (AR) and asthma are the most common allergic disorders worldwide. Aeroallergens are critical causative factors in the pathogenesis of these disorders and sensitization to aeroallergens differs in various countries and regions. Identification of the most common aeroallergen sensitization is crucial in the diagnosis and management of AR and asthma. We examined the distribution of aeroallergen sensitizations detected by skin prick tests (SPTs) in adult patients with AR and/or asthma in the city of Bursa. Materials and methods: Five hundred forty-five patients who underwent a SPT and were diagnosed with rhinitis and/or asthma in the Uludag University Faculty of Medicine's Department of Immunology and Allergic Diseases Outpatient Clinic from March 2018 to August 2018 were retrospectively evaluated. SPTs with standard extracts including house dust mites, pollens, molds, animal dander, and latex were performed for patients. Results: A total of 545 patients were included and most of the patients (270; 49.5%) were between 30 and 49 years of age. The prevalence of atopy was 57.9%. The most common aeroallergens detected in SPTs were Dermatophagoides farinae (50%) and D. pteronyssinus (44%), followed by grass-rye mix (43%), grass mix (38.6%), olive (33.2%), and wheat (32.3%). The sensitization to olive pollen was higher in cases of mild asthma (52%), while sensitization to D. farinae was higher in patients with mild and moderate asthma (54.5%, 54.2%) (P < 0.05) . Conclusions: Our study revealed that house dust mite was the most common sensitizing aeroallergen in patients with AR and asthma while pollens were the most common allergen in patients with only AR. The sensitization to grass and olive pollen was higher in cases of mild asthma than moderate and severe. Regional allergy panels may provide important clinical clues for characteristics and courses of allergic diseases.

[Causes of mediastinal/hilar granulomatous lymphadenitis]. / Mediastinal/hiler granülomatöz lenfadenit etyolojisi.

INTRODUCTION: Granulomatous lung disease (GLD) is caused by a wide range of conditions and it is challenge for pulmonologist. A detailed history of exposures is fundamental in GDL and has been found pivotal to reach a precise diagnosis. MATERIALS AND METHODS: Between September 2014 and December 2016, the distribution of patients diagnosed with granulomatous lymphadenitis in the mediastinal/hilar lymph nodes by endobronchial ultrasound (EBUS) or mediastinoscopy was analyzed. To be listed as 'confident', a diagnosis of sarcoidosis required compatible histological, radiological and clinical findings in conjunction with negative cultures. Infectious entities listed as 'confident' had either microorganisms in tissue section, positive culture, positive serology or positive antigen detection in a consistent clinical pathological setting. RESULT: Granulomatous lymphadenitis was detected in 110 patients. The included 110 cases consisted of 70.9% women and median age of 53 (range 44-61) years. The final diagnosis of the patients was accepted to be sarcoidosis in 79 (71.8%), sarcoid like granulomas in 7 (6.4%), tuberculosis in 4 (3.6%), silicosis in 4 (3.6%), drug-associated granuloma in 2 (1.8%), hypersensitivity pneumonitis in 1 (0.9%), Chron disease in 1 (0.9%), unspecified in 12 (10.9%). Three patients were classified as tuberculosis based on culture. CONCLUSIONS: In this study, we found that the most common cause of granulomatous lymphadenitis was sarcoidosis. Contrary to expectations, the number of patients diagnosed with tuberculosis was very low.

Syncope as a subject of the risk assessment of pulmonary thromboembolism to be used for: A cross-sectional study.

INTRODUCTION: Syncope is infrequent in pulmonary thromboembolism (PTE) yet might be indicative of haemodynamic instability. The prognostic role of syncope in PTE has not been well documented. OBJECTIVES: In this study, the association between risk classification of the European Society of Cardiology and syncope was investigated in the normotensive PTE patients. METHODS: We retrospectively screened electronic medical records of patients who were admitted in 2 tertiary care hospital and diagnosis of PTE with computed tomography pulmonary angiography. Patients with hypotension (high risk) at the time of admission were excluded from the study. RESULTS: Of 5% patients (16/322) had syncope with the proportion of 81.3% (13/16) in the intermediate high risky group, 18.7% (3/16) in intermediate low risk group and 0% in low risk group. Mortality rate was higher in subjects with syncope (25% vs 11.1%) although it was not it was not statistically significant (P = NS). In those with syncope, the central venous thrombus was more frequent than those without it (78.6% vs 30.1%, P = .008). Only heart rate and intermediate high-risk group were retained as independent predictors of syncope selection in the multivariate logistic regression. CONCLUSION: Although syncope is positively correlated with the severity of PTE, it does not predict the prognosis alone. Nonetheless, syncope in patients with PTE can be considered as an important alarming stimulus for clinical course.

[Bilateral total lung lavage in a patient with pulmonary alveolar proteinosis]. / Pulmoner alveoler proteinozisli hastada iki tarafli total akciger lavaji.

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease characterised by alveolar accumulation of surfactant composed of proteins and lipids. Three main categories of PAP have been defined depending on the aetiology: primer/idiopathic, neonatal/congenital, secondary and exogenous/environmental exposure. Radiologically diffuse ground glass opacities, interlobular and intralobular septal thickening is seen. Although open lung biopsy is accepted as the gold standard in diagnosis, it can be diagnosed by showing bronchoalveolar lavage (BAL) fluid with a milky appearance and periodic acid-schiff (PAS) positive globules in biopsy with clinical and radiological findings. Theraphy for PAP are supportive care (oxygen), total lung lavage, inhale/subcutaneous granulocyte macrophage colony stimulating factor (GM-CSF), rituximab, plasmapheresis, lung transplantation. We report a case of PAP presented with cough and shortness of breath, diagnosed with BAL and transbronchial lung biopsy, treated by total lung lavage by reviewing literature.

Classification of high-risk with cardiac troponin and shock index in normotensive patients with pulmonary embolism.

Accurate risk stratification of normotensive patients with acute pulmonary embolism (PE) require further investigation. We aimed to develop a simple model using clinical (shock index) and laboratory findings (cardiac Troponin, echocardiography) to assess the risk of 30-day mortality in normotensive patients with acute PE. In this retrospective study, 489 normotensive patients with acute PE diagnosed objectively. The primary end-point was defined as a all cause 30-day mortality. Shock index was calculated on admission. The primary end-point occurred in 67 (13.7%, 95% CI 10.7-16.8) patients with acute PE. Predictors of complications included elevated cardiac troponin (OR 1.7, 95% CI 1.3-2.2) and shock index (OR 1.3, 95% CI 1.1-1.5) by multivariable analysis. Risk index point was created based on OR. The model identified stages (stage I: 0-1 point, stage II: 2 points and stage III: 3 point) with 30-day mortality rates of 4.3, 19 and 38.6 %, respectively. The shock index and cardiac troponin can be safely used in combination to determine intermediate risk in patients with PE in emergency departmant. The study provided observations that will require prospective validation before the proposed risk score is adopted in clinical practice.

[Inflammatory bowel disease and pulmonary embolism: Because of 3 cases]. / Inflamatuvar bagirsak hastaligi ve pulmoner emboli: 3 olgu nedeniyle.

Thromboembolic complications are an important cause of morbidity and mortality in inflammatory bowel diseases (IBD). Thromboembolic events are observed more frequently during acute flare of the disease, especially patients received steroid therapy. Increase in awareness and especially anticoagulation prophylaxis in these patients are extremely important. In this article, three cases with diagnosed pulmonary thromboembolism (PE) were presented accompanied by the current literature.
