    Title translation The role of fixed dose combinations of inhaled cortikosteroids, long acting beta-2 agonists, and long acting muscarinic antagonists (ICS/LABA/LAMA) in the treatment of asthma.
    Abstract The effective treatment of asthma is important in terms of improving the quality of life and decreasing the number of hospital admissions due to acute exacerbations. Parasymphatic activity is increased in patients with asthma. This is one of most important part of airway obstruction which has a great potential for reversibility. The evidence about the synergic interaction between inhaled corticosteroids (ICS), long acting beta-2 agonists (LABA), and long acting muscarinic antagonists (LAMA) encourages the use of LAMA in asthma. Tiotropium treatment was found to be successful in patients with recurrent exacerbations in whom asthma was uncontrolled despite treatment with other add on treatments that were recommended at GINA step 4. These findings triggered several clinical studies on fixed dose ICS/LABA/LAMA for asthma treatment. Three studies that have been published recently showed that fixed dose ICS/LABA/LAMA improved the lung functions and decreased the exacerbation rate without increasing the dose of ICS or LABA in asthma. In this review, the mechanisms of action of LAMA in asthma were summarized and possible role of fixed dose ICS/LABA/ LAMA in asthma treatment was discussed under the light of current literature.

    Title translation GINA 2019 - step 1 and 2 treatment in asthma: Updates with reasons behind.
    Abstract Asthma is a heterogeneous lung disease characterized by chronic airway inflammation. It was suggested that patients with mild asthma symptoms could be managed with as-needed short-acting β2-agonists (SABA) in previous years. In 2019, GINA made a radical change and recommended that SABA should not be used as monotherapy in patients with mild asthma, but instead as-needed low-dose inhaled corticosteroid (ICS)-formoterol or "additional low-dose ICS taken whenever SABA is taken" treatments should be commenced to relieve and control symptoms. The approach emerged in the light of the studies that indicate the increased risk of severe exacerbation and asthma-related death due to overuse of SABA. The present article aimed to enlighten the updates in GINA 2019 step 1 and 2 treatment, the grounds for these updates with the supportive studies.

    Abstract Background: Anaphylaxis is a very dynamic issue with its incidence and trigger profile changing over the years. We aimed to compile the characteristics of anaphylaxis cases diagnosed in our clinic prospectively and to make a comparison between diagnostic criteria proposed by National Institute of Allergy and Infectious Diseases/Food Allergy and Anaphylaxis Network (NIAID/FAAN) and World Allergy Organization (WAO).
    Method: Three-item diagnostic criteria recommended by NIAID/FAAN (2006) were used in the diagnosis of anaphylaxis. The clinical features of the cases, risk factors, etiologies, severity of anaphylaxis, and treatment approach were determined. The same patients were also classified by current WAO diagnostic criteria.
    Results: A total of 204 patients (158F/46 M, median age 45.3 years) were included. Drugs (65.2%), venom (9.8%) and food allergies (9.3%) were the top 3 etiologies. Among drug triggers, chemotherapeutics were the most common (17.7%), followed by antibiotics (15.3%) and non-steroidal anti-inflammatory drugs (14.2%). The patients were mostly diagnosed with the second criterion (84.8%), followed by the first criterion (11.8%) and the third criterion (3.4%) of the NIAID/FAAN criteria. In terms of WAO criteria, 82.8% of the patients were diagnosed with the first criterion, and 14.3% with the second criterion while 2.9% of the patients did not meet the WAO criteria. The severity of anaphylaxis was evaluated as grade-2, 3 and 4 in 30.9%, 64.2%, and 4.9% of the patients, respectively. Adrenaline was administered to 31.9% of the patients especially who had angioedema and bronchospasm (p = 0.04).
    Conclusion: Our data suggest that covering more details in patient's history may prevent possible underdiagnosis and WAO diagnostic criteria seem to be insufficient in some patients. We believe that our results will contribute to the literature on anaphylaxis and would be groundwork for future studies.

    Abstract Rituximab is a chimeric monoclonal antibody (mAb) against CD20 molecule which is expressed on human B cells. It has been used for the treatment of various lymphoid malignancies, lymphoproliferative diseases, and rheumatologic disorders. Rituximab is generally well tolerated. However, increased use of rituximab has been associated with hypersensitivity reactions (HSRs), which can be classified as infusion-related, cytokine-release, type I (IgE/non-IgE), mixed, type III, and type IV reactions. Immediate infusion-related reactions to rituximab are quite common and decrease in frequency with subsequent infusions. However, in about 10% of patients, severe infusion-related reactions develop, which prevent its use. Some of the immediate infusion reactions are due to a cytokine-release but some reactions raise concerns for type I (IgE/non-IgE) hypersensitivity. Recent studies have shown the presence of serum anti-rituximab antibodies, either represented by the IgG or IgE isotype. In some cases, clinical manifestations of IgE-mediated reactions and cytokine-release reactions partially overlap, which is called a mixed reaction. Classified as Type III reaction, rituximab-induced serum sickness reactions have been reported in patients with autoimmune diseases and hematological malignancies. The classic serum sickness triad (fever, rash, and arthralgia) has been observed in patients mainly with an underlying rheumatologic condition. Severe delayed type IV hypersensitivity reactions including non-severe maculopapular rash to severe reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis have been rarely reported following rituximab injection. Comprehensive reviews focused on rituximab-induced HSRs are scarce. We aimed to review clinical presentations, underlying mechanisms of rituximab hypersensitivity, as well as management including rapid drug desensitization.

    Title translation Anti-IL-5 treatments in severe eosinophilic asthma: real life datas.
    Abstract Randomized controlled studies have shown that anti-IL-5 treatments reduce the need for oral corticosteroids, annual asthma exacerbation and hospitalization rates, blood eosinophil count and increase FEV1 values, asthma control, and quality of life in patients with eosinophilic severe asthma. Although the number of real-life studies with anti-IL-5 is limited, there are 10 real life studies with mepolizumab, one real life study with benralizumab and one real life study with reslizumab in the current literature. Similar to randomized controlled trials, real-life studies reported that a reduction in the need for oral corticosteroids, annual asthma exacerbation and hospitalization rates, and blood eosinophil counts and increase FEV1 values, asthma control test and quality of life scores, Response criteria were defined in some of the real-life studies and although different response rates were given according to these criteria, most of the patients with severe eosinophilic asthma showed high response rates to anti-IL-5 treatments. In real-life studies evaluating the safety of anti-IL-5 treatments, the most common adverse effect is mild local injection site reaction that does not require treatment, in conclusion, real-life studies suggest that all three anti-IL-5 treatments in clinical practice are effective and well tolerated.

    Title translation Biological Treatments in patients with ABPA.
    Abstract Allergic Bronchopulmonary Aspergillosis (ABPA) is a pulmonary disease characterized by recurrent pulmonary opacities and bronchiectasis caused by Type 1 hypersensitivity to A. fumigatus. Asthma is an important part of the disease and is generally in severe form. It is thought that immunoglobulins against A. fumigatus, Th2-derived cytokines such as IL-4, IL-5 and IL-13 and eosinophilic inflammation play a role in the pathogenesis of the disease. Monoclonal antibody treatments targeting IL-4, IL-5, IL-13 and IgE, which are involved in pathogenesis, have been used in asthmatic patients before. The main treatment of ABPA for exacerbations and remissions is oral corticosteroids (OCS). However, in cases where the corticosteroid dose cannot be reduced or side effects develop, monoclonal agents may be added to the treatment. Monoclonal agents such as omalizumab, mepolizumab, benralizumab and dupilumab targeting cytokines involved to the patogenesis have been used in patients with ABPA. Omalizumab has shown a reduction in exacerbations and OCS requirements, improvement in asthma symptoms and improvement in pulmonary function parameters. With mepolizumab, a decrease in OCS dose, decrease in blood eosinophil count, clinical improvement and radiological improvement were observed. Benralizumab reduced, the number of eosinophil or even almost nullified as well as clinical recovery alongside with radiological improvement. With dupilumab, improvement in symptoms, discontinuation of OCS, but increase in eosinophil count at the beginning of treatment was reported. As a result, monoclonal antibodies were generally found to be successful and safe in patients with ABPA.

    Title translation The profile of severe asthmatics: Results from a specialized asthma clinic.
    Abstract Introduction: In patients with severe asthma, individualized treatment, and appropriate phenotyping are required to achieve control. In our study, our aim was to examine the characteristics of a specific patient group in a specialized tertiary asthma outpatient clinic, which is the primary setting for evaluating severe asthma patients, with the intention of obtaining national data.
    Materials and methods: In this cross-sectional observational study, sociodemographic, clinical presentations, laboratory results, and spirometry measurements of patients with severe asthma who were followed up in our specialized asthma outpatient clinic for at least one year were recorded. Patients were defined as eosinophilic if they had a blood eosinophil count of 300/µL or higher at least twice during the oral corticosteroid free-period or 150/µL or higher under oral corticosteroids as allergic if they had sensitization to at least one inhalant allergen consistent with their history.
    Result: Overall, 201 severe asthma patients (74.1% female) with a median disease duration of 15 (min-max= 1-49) years and a median follow-up duration of 7 (min-max= 1-40) years were analyzed. Most of the patients (56.7%) had adult-onset asthma [median age of onset was 32 (min-max= 10-62) years]. Overweight and obese patients were in the majority (31.8%, and 41.8%, respectively) and the median body mass index was 29 (min-max= 17.5-49.5). More than half of the patients (55.2%) had controlled asthma and the median Asthma Control Test score at the last visit was 23. Biologic therapies were applied to 73.1% (n= 147) of the patients [60.5% (n= 89) omalizumab, 39.5% (n= 58) mepolizumab]. Half of the group was allergic (49.3%) and three-quarters of them were eosinophilic (72.1%). Allergic patients had earlier asthma onset and had more controlled disease than nonallergic ones. Eosinophilic patients were younger and less obese than noneosinophilic patients. Obese and late-onset asthmatics had more uncontrolled disease than normal weight subjects and early onset patients.
    Conclusions: The high rate of disease control in the patients with severe asthma in the current study demonstrated the importance of targeted individualized therapy with accurate phenotyping in specialized asthma outpatient clinics.
