Clinical remission maintained and improved over time in patients with severe asthma treated with omalizumab.

BACKGROUND: Clinical remission has recently been proposed as a possible treatment goal even in severe asthma. In this real-world study, we aimed to assess the achievement rate and predictive factors of clinical remission using omalizumab in patients with severe asthma. METHODS: This retrospective observational study included patients with severe asthma initiated with omalizumab therapy and recruited from the asthma clinic of the Akdeniz University Hospital, Turkey. Clinical remission was defined as patients who received no oral corticosteroid (OCS) therapy; showed no exacerbations; showed an asthma control questionnaire score of ≤ 1, asthma control test (ACT) of ≥ 20, or both and, FEV1 of ≥ 80% predicted. RESULTS: A total of 58 patients were included in the study, with an average age of 56.4 ± 13.6 years. The mean duration of asthma was 23.5 ± 11.8 years and the mean duration of omalizumab treatment was 80.05 ± 35.04 months. Clinical remission rates were 25.9% in the first and second year, 34.0% in the third year, 34.1% in the fourth year and 47.4% in the fifth year. Pre-omalizumab ACT, FEV1 (%) and OCS use were significantly higher in patients with clinical remission at 1 year. Logistic regression analyses showed that none of the factors predicted clinical remission. CONCLUSION: Omalizumab has the potential to induce disease remission in a significant proportion of people with severe asthma, and this is maintained and improved over time.

Real-life data in the treatment and follow-up of idiopathic pulmonary fibrosis: A single-center study.

Introduction: The aim of this study was to evaluate the real-life treatment and follow-up data of patients with idiopathic pulmonary fibrosis (IPF) in a singlecenter setting. Materials and Methods: The study included consecutive patients diagnosed with IPF who were followed up at the Akdeniz University, between January 1, 2014 and December 31, 2022. Patient information was obtained from the hospital automation system. Result: A total of 227 patients with a mean age of 72.0 ± 8.2 years were included in the study. One hundred sixty-seven patients (73.6%) received pirfenidone while 60 patients (26.4%) received nintedanib treatment. Radiological findings were used to diagnose IPF in 79.3% (n= 180) of cases. Mean duration of antifibrotic treatment was 26.3 ± 19.9 months. Of the patients, 49.8% experienced hospital admissions during the treatment course, with respiratory reasons accounting for a majority of these admissions (33.6%). Disease exacerbation was detected in 26.6% of the patients during the treatment period. At least one side effect was observed in 126 patients (55.5%), with a significant portion of these side effects being mild to moderate (n= 79, 34.8%). Disease progression was observed in 21.6% of the patients under antifibrotic treatment. Dose reduction was necessary in 22.9% of the patients, with an average duration of dose reduction of 29 months. Antifibrotic treatment was switched to another medication in 24.2% of the patients. There were no statistically significant differences in baseline forced vital capacity (FVC) levels between the two groups (p= 0.314) while the diffusing capacity of the lungs for carbon monoxide (DLCO) level was higher in the nintedanib group (p= 0.024), and the six-minute walk distance was shorter (p= 0.049). Conclusions: In this study evaluating patients with IPF under follow-up in our hospital, it was observed that the majority of patients consisted of elderly male individuals, frequent hospitalizations were due to respiratory reasons, and both antifibrotic medications were well tolerated with a similar side effect profile.

Alterations in plasma miR-21, miR-590, miR-192 and miR-215 in idiopathic pulmonary fibrosis and their clinical importance.

BACKGROUND: Many studies have revealed that microRNA (miRNA) molecules may take part in idiopathic pulmonary fibrosis (IPF). But, the role of miRNAs in the development of IPF is not yet clear. METHODS: We investigated the plasma levels of miR-21, miR-590, miR-192, and miR-215 in IPF (n = 88) and healthy control (n = 20) groups in this study. We compared the expression levels of target miRNAs in patients with IPF and healthy participants. We grouped the patients with IPF according to age, forced vital capacity, carbon monoxide diffusing capacity (DLCO), gender-Age-pulmonary physiology (GAP) score, the presence of honeycombing and compared the expression levels of target miRNAs in these clinical subgroups. RESULTS: 82 (93.18%) of the patients with IPF were male and the mean age was 66.6 ± 8.6 years. There was no significant difference between the gender and age distributions of IPF and the control group. The mean plasma miR-21 and miR-590 levels in IPF group were significantly higher than in the control group (p < 0.0001, p < 0.0001, respectively). There was no significant difference between the miR-192 and miR-215 expression levels of the IPF and control group. Both miR-21 and miR-590 correlated positively with age (p = 0.041, p = 0.007, respectively) while miR-192 and miR-215 displayed a negative correlation with age (p = 0.0002, p < 0.0001, respectively). The levels of miR-192 and miR-215 increased as the GAP score decreased. The levels of miR-192 in patients with honeycombing were significantly lower than in those without honeycombing (p = 0.003). CONCLUSIONS: Our study showed that both miR-21 and miR-590 were overexpressed in IPF. The miR-21 and miR-590 were associated with DLCO, while miR-192 and miR-215 were associated with the GAP score and honeycombing.

Tolerability and efficacy of second-line antifibrotics in patients with idiopathic pulmonary fibrosis.

BACKGROUND: The antifibrotic drugs nintedanib and pirfenidone reduce disease progression in idiopathic pulmonary fibrosis (IPF) and have also shown to improve survival. Switching first-line antifibrotic drug may required in IPF due to disease progression or intolerable adverse effects. The aim of this study was to assess the safety and efficacy of second-line antifibrotic treatment in patients with IPF. MATERIAL AND METHODS: This retrospective, multicenter study was conducted at three referral interstitial lung disease centers who received first-line antifibrotics more than one month and switched the treatment to a second-line antifibrotic agent during January 2016-June 2021. The drug's safety was evaluated based on the type of adverse effect. Disease progression was defined as an absolute decline in FVC of >10% within 12 months with or without radiological progression. RESULTS: Among 629 consecutive patients with IPF, 66 patients switched antifibrotics. The median duration of antifibrotics was 13 (1-41) months prior to the switch, and 14 (2-42) months after the switch. The mean age was 70.6 ± 8.9 years and, median FVC (%) was 72.1 ± 18.7 at the initiation of first-line antifibrotics. The most common reason for the switch was disease progression (56%) followed by severe adverse effects (SAEs) (44%). SAEs were significantly less observed after the switch compared before the switch (43.9% vs12.1%, respectively, p < 0.001). Eighteen patients had adverse effects due to second-line antifibrotics. Among these patients, 10 had mild adverse effects and 8 had severe adverse effects. While there was no change in the FVC (%) values in 30.3% patients 12 months after the first-line antifibrotic treatment (before the switch), there was no change in the FVC (%) values in 40% patients at the end of 12 months after the switch. Fourteen patients (42.4%) who received antifibrotic treatment before the switch had more than 10% decline in FVC (%) at the end of 12 months. Eight patients (32.0%) had 10% or more decline in FVC (%) 12 months after the switch. CONCLUSION: Patients with IPF who do not tolerate first-line antifibrotic treatment or those showing disease progression despite treatment, switching antifibrotics may be a feasible management strategy.

Evaluation of efficacy and safety of pirfenidone 200 mg tablets in patients with idiopathic pulmonary fibrosis in a real-life setting

Background/aim: Phase III trials have demonstrated a significant efficacy and an acceptable safety for pirfenidone in patients having mild to moderate idiopathic pulmonary fibrosis (IPF). Real-life data on the use of pirfenidone 200 mg tablets are limited. This study aimed to investigate the efficacy and safety of pirfenidone 200 mg tablets for the treatment of IPF in a real-life setting. Materials and methods: A retrospective, multicenter study conducted in four university hospitals in Turkey between January 2017 and January 2019. Clinical records of patients diagnosed with mild to moderate IPF and receiving pirfenidone (200 mg tablets, total 2400 mg/day) were reviewed retrospectively and consecutively. Pulmonary function measurements including forced vital capacity (FVC%) and diffusing capacity of the lungs for carbon monoxide (DLCO%) were analyzed at baseline and after 6-month of pirfenidone treatment. Descriptive statistics were expressed as mean, standard error or median (minimum-maximum), number and percentage, where appropriate. Results: The study included 82 patients, of whom 87.8% were males (mean age, 66 years). After 6-month of treatment, 7 patients discontinued the treatment. Of the remaining 75 patients, 71 (94.6%) remained stable, 4 (5.4%) had progressive disease as evident by a decline in the FVC% of at least 10% while on treatment, and 45 (61.3%) had improved cough. At least one adverse event (AE) associated with the treatment was observed in 28 (37.3%) patients. Conclusion: Pirfenidone 200 mg was effective and well tolerated and associated with relatively mild and manageable AEs in IPF patien

Asthma control and adherence in newly diagnosed young and elderly adult patients with asthma in Turkey.

OBJECTIVE: This study aimed to evaluate the factors that affect asthma control and adherence to treatment in newly diagnosed elderly asthmatics in Turkey compared with younger patients. METHODS: This real-life prospective observational cohort study was conducted at 136 centers. A web-based questionnaire was administered to the patients who were followed up for 12 months. RESULTS: Analysis included 1037 young adult asthma patients (age <65 years) and 79 elderly asthma patients (age ≥65 years). The percentage of patients with total control in the elderly and young groups were 33.9% and 37.1% at visit 1, 20.0% and 42.1% (p = 0.012) at visit 2, and 50.0% and 49.8% at visit 3, respectively. Adherence to treatment was similar for both groups. Visit compliance was better in the elderly group than in the young group at visit 1 (72.2% vs. 60.8%, p = 0.045), visit 2 (51.9% vs. 34.9%, p = 0.002), and visit 3 (32.9% vs. 19.4%, p = 0.004). Adherence to treatment increased with asthma control in both groups (both p < 0.001) but decreased with the presence of gastritis/ulcer, gastroesophageal reflux, and coronary artery disease in the elderly. CONCLUSIONS: Asthma control and adherence to treatment were similar for the elderly and young asthma patients, though the follow-up rate was lower in young patients. The presence of gastritis/ulcer, gastroesophageal reflux and coronary artery disease had negative impacts on the adherence to treatment in elderly adult patients.

Long-Term Omalizumab Treatment: A Multicenter, Real-Life, 5-Year Trial.

BACKGROUND: Omalizumab has demonstrated therapeutic benefits both in controlled clinical trials and real-life studies. However, research concerning the long-term effects and tolerability of omalizumab is needed. The main objective of this study was to evaluate the effectiveness and tolerability of treatment with omalizumab for up to 5 years. METHODS: A multicenter, retrospective, chart-based study was carried out to compare documented exacerbations, hospitalizations, systemic steroid requirement, FEV1, and asthma control test (ACT) results during 1 year prior to omalizumab treatment versus at 1, 3, and 5 years of treatment. Adverse events and reasons for discontinuation were also recorded at each time point. RESULTS: Four hundred and sixty-five patients were enrolled in the study. Outcome variables had improved after the 1st year and were sustained after the 3rd and 5th years of treatment with omalizumab. Omalizumab treatment reduced the asthma exacerbation rate by 71.3% (p < 0.001) at 1 year, 64.3% (p < 0.001) at 3 years, and 54.8% (p = 0.002) at 5 years. The hospitalization rate also decreased; by the 5th year of the treatment no patients were hospitalized. ACT results had also improved significantly: 12 (p < 0.001) at 1 year, 12 (p < 0.001) at 3 years, and 12 (p = 0.002) at 5 years. Overall, 12.7% of patients reported adverse events (most of these were mild-to-moderate) and the overall dropout rate was 9.0%. CONCLUSION: Omalizumab had a significant effect on asthma outcomes and this effect was maintained over 5 years. The drug was found to be generally safe and treatment compliance was good.

Antibiotic treatment outcomes in community-acquired pneumonia

Background/aim: The optimal empiric antibiotic regimen for patients with community-acquired pneumonia (CAP) remains unclear. This study aimed to evaluate the clinical cure rate, mortality, and length of stay among patients hospitalized with community- acquired pneumonia in nonintensive care unit (ICU) wards and treated with a ß-lactam, ß-lactam and macrolide combination, or a fluoroquinolone. Materials and methods: This prospective cohort study was performed using standardized web-based database sheets from January 2009 to September 2013 in nine tertiary care hospitals in Turkey. Results: Six hundred and twenty-one consecutive patients were enrolled. A pathogen was identified in 78 (12.6%) patients. The most frequently isolated bacteria were S. pneumoniae (21.8%) and P. aeruginosa (19.2%). The clinical cure rate and length of stay were not different among patients treated with ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone. Forty-seven patients (9.2%) died during the hospitalization period. There was no difference in survival among the three treatment groups. Conclusion: In patients admitted to non-ICU hospital wards for CAP, there was no difference in clinical outcomes between ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone regimens.

[The pilgrimage and the burden of pneumococcal disease in adults]. / Hac ve eriskinlerde pnömokok hastaligi yükü.

Pneumococcal disease is responsible for significant morbidity and mortality. All over the world, 1.6 million people die of pneumococcal disease every year; this estimate includes the deaths of 1 million children aged less than 5 years and the deaths of 600.000- 800.000 adults. The burden of pneumococcal disease is high in adults. Increasing age and the presence of comorbidity has a significant affected of the risk of developing the disease. During mass gatherings, such as pilgrimage individuals, is exposed to severe community-acquired pneumococcal infections. Individuals who has Streptococcus pneumoniae in nasopharynx, have the potential to infection and leave exposed to the risk of pneumococcal disease the other Individuals with sneezing, coughing or out of breath, given breath through droplets of these microorganisms. In the present review, the relationship of pneumococcal disease in adults and pilgrimage, vaccination strategies will be considered and then during a visit to Pilgrimate and Umrah pilgrims against the current vaccine recommendations will be summarised.

Real life profile of asthma and chronic obstructive pulmonary disease patients in Turkey.

INTRODUCTION: Despite the presentation of similar symptoms, the airway diseases have different underlying pathophysiological processes and must be distinguished to enable the administration of appropriate treatment. In several studies the clinician- and patient-related causes of poor compliance to treatment in asthma/chronic obstructive pulmonary disease (COPD) patients have been evaluated. This study aimed to determine the clinical and sociodemographic characteristics of newly diagnosed treatment-naïve asthma and COPD patients in Turkey. MATERIALS AND METHODS: This national, multicentre, prospective, observational study was conducted in 122 centres. A questionnaire including items related to demographic, clinical, laboratory parameters was applied. All patients were intended to be followed-up for 12 months. RESULT: 1892 adult patients (1116 asthma and 776 COPD) from 122 centres were enrolled. Overall 95%, 86% and 65% of intermittent, mild persistent and moderate persistent asthma patients were over-treated. Among COPD patients, the percentages of over-treated patients were 66%, 79% and 82% for those with GOLD stage A, B and C. Physicians' adherence to guidelines was appropriate in 93% of severe persistent asthma patients and 89% of GOLD stage D COPD patients. Among patients with high compliance to treatment, proportion of asthma patients with total control was 44% and that of COPD patients at GOLD stage A was 41%. In consecutive two visits, this figure increased to 52% and 63% in asthma patients and 54% and 50% in COPD patients. CONCLUSIONS: The main findings are: (a) patients are frequently over-treated and (b) patients do not adhere to visits as expected, in both asthma and COPD.

Evaluation of long-term safety and efficacy of omalizumab in elderly patients with uncontrolled allergic asthma.

BACKGROUND: Severe asthma management in elderly patients may be difficult because of increased comorbid conditions, polypharmacy, physiologic changes that occur with aging, incorrect use of inhaler devices, and poor adherence. OBJECTIVE: To evaluate the long-term safety and efficacy of the anti-IgE antibody omalizumab in elderly (aged ≥65 years) patients with uncontrolled allergic asthma. METHODS: The efficiency and adverse effects of omalizumab treatment were evaluated based on data extracted from medical records. Patients were evaluated monthly for efficacy and adverse reactions. Treatment efficacy was evaluated by level of asthma symptom control, using the Global Initiative for Asthma guideline. RESULTS: Nineteen consecutive elderly patients with asthma (female to male ratio, 14:5) formed our cohort. The mean (SD) age, disease duration, and total IgE level were 69.3 (5.8) years, 19.4 (8.6) years, and 299.1 (197.2) IU/mL, respectively. The mean (SD) duration of omalizumab treatment was 35.6 (17.8) months (range, 9-66 months). All the patients had at least 1 perennial inhalant allergen sensitivity and had uncontrolled allergic asthma. Elderly patients experienced no significantly important adverse reaction considered to be related to omalizumab treatment. Only 1 patient had a local adverse reaction and 1 had myalgia that was considered to be drug related. After omalizumab treatment, asthma symptoms were well controlled in 9 patients (47.4%) and partly controlled in 8 patients (42.1%). Two of the patients (10.5%) still had uncontrolled asthma. CONCLUSION: Our study found that omalizumab is a well-tolerated and effective therapy for elderly patients with uncontrolled asthma.

Omalizumab treatment in asthma-COPD overlap syndrome.

INTRODUCTION: Asthma-chronic obstructive pulmonary disease overlap syndrome (ACOS) is a poorly understood disease with an increasing morbidity and mortality. Currently, the most effective treatment for ACOS is unknown and omalizumab for ACOS has not yet been reported. METHODS: We report our experience with anti-IgE, omalizumab treatment on 3 patients with ACOS as a retrospective case study. RESULTS: After 1 year of omalizumab treatment, patients experienced significantly lower rates of asthma exacerbation and hospitalization and better asthma control test results. CONCLUSION: Our study shows that omalizumab may be an effective and safe therapy for patients with ACOS. However larger randomized trials are needed.

Clinical characteristics and outcome of healthcare associated pneumonia in Turkey.

INTRODUCTION: Pneumonia in cases with preceding hospitalization, hemodialysis, intravenous therapy, wound care, or chemotherapy within the prior 30 days and residence in nursing homes are defined as healthcare associated pneumonia (HCAP). The aim of this study was to compare the demographic and laboratory data, isolated causative agents and prognosis of patients with community-acquired pneumonia (CAP) and HCAP in a large population in Turkey. MATERIALS AND METHODS: The data of 785 cases (average age 65.3 ± 16.4, 530 male) registered to Turkish Thoracic Society Respiratory Infections Study Group CAP database (TURCAP) were examined. The demographic data, clinical history, pneumonia severity scores (PSI), laboratory and radiologic findings of the CAP and HCAP patients were compared. RESULT: Out of 785 cases, 207 (26.4%) were diagnosed with HCAP and 578 (73.6%) with CAP. Among HCAP cases, 140/207 (67.6%) had preceding hospitalization in the last 90 days, 28/207 (13.5%) were on a hemodialysis program during the previous 30 days and 22/207 (10.6%) were staying in nursing homes. Patients with HCAP more frequently had comorbidities (93.2% vs. 81.6%; p= 0.001) and higher PSI scores (103.9 ± 37.2 vs. 94.6 ± 35.4; p= 0.002) compared to patients with CAP. A causative microorganism was isolated in only 12.1% (70/578) of CAP and 14.5% (30/207) of HCAP patients. The length of stay in hospital was higher in HCAP than CAP (8.6 ± 5.5 vs. 7.5 ± 6.1 days, p= 0.03); however the rates of treatment failure, intensive care unit admission and mortality were similar. CONCLUSIONS: In comparison to CAP, HCAP patients tend to have more severe disease, despite have no difference in mortality. The current criteria for HCAP do not predict worse clinical outcomes. Further work is required to define local risk factors for multidrug-resistant pathogens.

[Comparison of ampicillin-sulbactam/macrolide dual therapy versus fluoroquinolone monotherapy in hospitalized patients with community-acquired pneumonia]. / Toplumda gelisen pnömoninin tedavisinde ampisilin-sulbaktam/makrolid kombinasyonu ile tek basina florokinolon tedavilerinin karsilastirilmasi.

INTRODUCTION: For hospitalized patients, monotherapy with a respiratory Fluoroquinolone (F) and dual therapy combination a ampicilline-sulbactam + a macrolide (AS+M) are extensively used in the treatment of community-acquiredpneumonia (CAP). In this study, empirical AS + M combination therapy versus F monotherapy was compared in hospitalized adult CAP patients. PATIENTS AND METHODS: This retrospective study, patients with CAP hospitalized in Akdeniz University Hospital, Pulmonology Clinic between October 2009 and May 2013 were included in the study. RESULTS: During the study period, 123 patients received AS + M and 75 received F. Mean age was 66 years. The most frequent comorbidities were diabetes mellitus, chronic obstructive pulmonary disease and cardiovascular disease. Disease severity, age, sex, comorbid diseases, smoking history, laboratory findings, CURB-65 and PSI scores were similar for the two treatment groups at admission. The clinical success rate cure was similar for both groups (82.1% vs 88%; p= 0.314). Length of hospital stay (5.6 ± 3.9 days vs 5.9 ± 3.9 days, p= 0.223) and hospital cost (1.963 ± 3.723 TL vs 1.965 ± 7.172 TL, p= 0.975) were also nonsignificant in both groups. In-hospital, 30-day and 90-day mortality rates were not different in AS + M and F group (5.6% vs 6.6; 8.1% vs 8%; 20.3% vs 19%; 31.7% vs 26.9%, respectively). CONCLUSIONS: In conclusion, our study has showed ampicilline-sulbactam and macrolide combination and fluoroquinolone monotherapy have comparable clinical efficacy as well as mortality rates in hospitalized patients with CAP.

[Health-care associated pneumonia]. / Saglik bakimiyla iliskili pnömoni.

INTRODUCTION: Health-care associated pneumonia (HCAP) is defined as pneumonia that develops in patients with a history of recent hospitalization, hemodialysis as an outpatient, residence in a nursing home, outpatient intravenous therapy and home wound care. MATERIALS AND METHODS: We retrospectively assessed patients who have been hospitalized in Department of Chest Diseases, Akdeniz University, Faculty of Medicine due to HCAP between 1 January 2009 and 1 June 2012. Of the total 195 pneumonia cases, 76 (38.9%) was HCAP and 119 (61.1%) was CAP. RESULTS: Among HCAP cases, 61 (80.3%) had recent hospitalisation in the last 90 days, 7 (9.2%) went under hemodialysis in the last 30 days, 3 (3.9%) had a history of decubitus management in house, 1 (1.3%) had a long term accomodation in social-care center and 1 (1.3%) had a history of infusion therapy at home. Comorbidity in HCAP group was higher than CAP group (94.6% vs resp. 73.1%; p< 0.001) and mean PSI scores were also higher in HCAP group (104.4 - 90.2; p< 0.05). A causative microorganism was detected in 18 HCAP (23.6%) and in 11 CAP (9.2%) cases. It was determined that appropriate treatment was started in 73.7% of HCAP cases and 98.3% of CAP cases according to national and international guidelines (p< 0.001). Both mean hospitalization duration (12.7 ± 1.1 vs 7.8 ± 0.5 days, resp; p< 0.05) and mortality rates (22.4% vs 4.2%; p< 0.001) were higher in HCAP group. Furthermore, mean cost of hospitalization was also greater for HCAP group than CAP group (4150.6 ± 892 TL vs 2078.7 ± 571 TL; respectively p< 0.05). CONCLUSION: In conclusion; patient characteristics, comorbidity status, causative organisms, duration and cost of hospitalization and prognosis of patients with HCAP was different from patients with CAP.

The interrelations of radiologic findings and mechanical ventilation in community acquired pneumonia patients admitted to the intensive care unit: a multicentre retrospective study.

BACKGROUND: We evaluated patients admitted to the intensive care units with the diagnosis of community acquired pneumonia (CAP) regarding initial radiographic findings. METHODS: A multicenter retrospective study was held. Chest x ray (CXR) and computerized tomography (CT) findings and also their associations with the need of ventilator support were evaluated. RESULTS: A total of 388 patients were enrolled. Consolidation was the main finding on CXR (89%) and CT (80%) examinations. Of all, 45% had multi-lobar involvement. Bilateral involvement was found in 40% and 44% on CXR and CT respectively. Abscesses and cavitations were rarely found. The highest correlation between CT and CXR findings was observed for interstitial involvement. More than 80% of patients needed ventilator support. Noninvasive mechanical ventilation (NIV) requirement was seen to be more common in those with multi-lobar involvement on CXR as 2.4-fold and consolidation on CT as 47-fold compared with those who do not have these findings. Invasive mechanical ventilation (IMV) need increased 8-fold in patients with multi-lobar involvement on CT. CONCLUSION: CXR and CT findings correlate up to a limit in terms of interstitial involvement but not in high percentages in other findings. CAP patients who are admitted to the ICU are severe cases frequently requiring ventilator support. Initial CT and CXR findings may indicate the need for ventilator support, but the assumed ongoing real practice is important and the value of radiologic evaluation beyond clinical findings to predict the mechanical ventilation need is subject for further evaluation with large patient series.

Omalizumab (anti-IgE) therapy increases blood glucose levels in severe persistent allergic asthma patients with diabetes mellitus: 18 month follow-up.

BACKGROUND: Therapeutic anti-IgE antibodies (Xolair, omalizumab) able to reduce free IgE levels and to block the binding of IgE to Fcepsilon RI without cross-linking IgE and triggering degranulation of IgE-sensitised cells have been developed. METHODS: We had two male patients of severe persistent allergic asthma with type-2 diabetes mellitus at the ages of 57 and 52 and who had suffered a side-effect of increased blood glucose level that caused a need for an extra insulin injection to control the hyperglycemia. Their asthma was not under control, frequent emergency department admissions lead us to use omalizumab treatment. Assessment of clinical changes and adverse effects were evaluated at each bimonthly patient visit including vital signs, full physical examination, details of any allergy incidents, total and specific IgE levels, serum ECP (eosinophilic cationic peptid) levels, pulmonary function test, exhaled nitric oxide concentrations, and asthma control test. RESULTS: Both patients were on week 42 - 45 of omalizumab treatment with a the dosage of 375 and 300 mg when they had the adverse reaction we reported here; they also had no other complaints. Blood levels of ECP and high sensitive CRP (hs-CRP) were decreased after starting the treatment of anti-IgE. CONCLUSIONS: To our knowledge, this is the first time an association between omalizumab use and hyperglycemia has been documented. Every vial of Xolair (150 mg) contains 145.5 mg sucrose and it might increase the blood levels of glucose in diabetics. As a conclusion the prescribing information might have been revised based on post marketing surveillance data and reported such cases indicating that different side effects may occur beyond 2 hours of the injection.

Diagnostic Yield and Safety of Repeat Bronchoscopy in Pulmonary Disease: A Five-Year Retrospective Analysis.

AIM: In this study, we aim to analyze the frequency and indications of repeat bronchoscopic procedures performed at our hospital over a five-year period. METHODS: This retrospective study was conducted at the Department of Pulmonary Diseases, Akdeniz University, and included patients who underwent bronchoscopy between January 1, 2018, and May 31, 2024. Patients who required a repeat bronchoscopy were identified. Inclusion criteria for the repeat bronchoscopy group were non-diagnostic initial bronchoscopy or the need for additional samples for molecular testing in lung cancer patients. Exclusion criteria included patients with incomplete medical records or those who did not provide informed consent for the repeat procedure. FINDINGS: A total of 3877 patients underwent bronchoscopy in this time periods. Among these, 69 patients (1.8%) required a repeat bronchoscopy. The mean age of these patients was 61.3 ± 11.7 years, with 54 (78%) being male. The most common reason for the repeat procedure was the non-diagnostic outcome of the initial bronchoscopy (n=53, 77%), followed by cases where the initial bronchoscopy was diagnostic for lung cancer but insufficient for molecular testing (n=16, 23%).. Among the 16 patients who underwent molecular testing, sufficient samples for molecular tests were obtained in 12 patients (75%) following the second bronchoscopy. Molecular tests were negative for driver mutations in 6 patients, while 6 patients tested positive (PD-L1, n=5; EGFR, n=1). In 4 patients (25%), the sample was reported as insufficient for molecular testing. Patients who underwent repeat bronchoscopy had the second procedure an average of 38.5 ± 59.7 days after the initial procedure. No complications developed in patients undergoing repeat bronchoscopy, except for bleeding not requiring intervention related to the bronchoscopy procedure. CONCLUSION: In conclusion, regardless of the reason, repeated bronchoscopy in suitable patients is safe and has a high diagnostic yield.

Bronchiectasis in Türkiye: Data from a Multicenter Registry (Turkish Adult Bronchiectasis Database).

Background: Bronchiectasis is a chronic lung disease characterized by permanent bronchial wall dilatation. Although it has been known as an orphan disease, it has recently gained attention because of registry-based studies and drug research. Aims: We aimed to use a multicenter database to analyze and compare data regarding the etiology, associated comorbidities, microbiological characteristics, and preventive strategies of bronchiectasis in Türkiye to those of other countries. Study Design: A multicenter prospective cohort study. Methods: The multicenter, prospective cohort study was conducted between March 2019 and January 2022 using the Turkish Adult Bronchiectasis Database, in which 25 centers in Türkiye participated. Patients aged > 18 years who presented with respiratory symptoms such as cough, sputum, and dyspnea and were diagnosed with non-cystic fibrosis bronchiectasis using computed tomography were included in the study. Demographic information, etiologies, comorbidities, pulmonary functions, and microbiological, radiological, and clinical data were collected from the patients. Results: Of the 1,035 study participants, 518 (50%) were females. The mean age of the patients was 56.1 ± 16.1 years. The underlying etiology was detected in 565 (54.6%) patients. While postinfectious origin was the most common cause of bronchiectasis (39.5%), tuberculosis was identified in 11.3% of the patients. An additional comorbidity was detected in 688 (66.5%) patients. The most common comorbidity was cardiovascular disease, and chronic obstructive pulmonary disease (COPD) and bronchiectasis was identified in 19.5% of the patients. The most commonly detected microbiological agent was Pseudomonas aeruginosa (29.4%). Inhaled corticosteroids (ICS) were used in 70.1% of the patients, and the frequency of exacerbations in the last year was significantly higher in patients using ICS than in nonusers (p < 0.0001). Age [odds ratio (OR): 1.028; 95% confidence interval (CI): 1.005-1.051], cachexia (OR: 4.774; 95% CI: 2,054-11,097), high modified medical research council dyspnea scale score (OR: 1,952; 95% CI: 1,459-2,611), presence of chronic renal failure (OR: 4,172; 95% CI: 1,249-13,938) and use of inhaled steroids (OR: 2,587; 95% CI: 1,098-6,098) were significant risk factors for mortality. Mortality rates were higher in patients with COPD than in those with no COPD (21.7-9.1%, p = 0.016). Patients with bronchiectasis and COPD exhibited more frequent exacerbations, exacerbation-related hospitalizations, and hospitalization in the intensive care unit in the previous year than patients without COPD. Conclusion: This is the first multicenter study of bronchiectasis in Türkiye. The study results will provide important data that can guide the development of health policies in Türkiye on issues such as infection control, vaccination, and the unnecessary use of antibiotics and steroids.

The accuracy of autotitrating CPAP-determined residual apnea-hypopnea index.

PURPOSE: Autotitrating continuous positive airway pressure (auto-CPAP) devices not only titrate CPAP pressures but also measure residual respiratory events. The aim of the present study was to determine the accuracy of auto-CPAP-derived residual apnea-hypopnea index (AHI). METHODS: We studied 137 consecutive patients (72.3% men) with obstructive sleep apnea from January 2008 to December 2010 who underwent in-laboratory overnight polysomnography (PSG) using auto-CPAP. We excluded patients with comorbidities like congestive heart disease, chronic obstructive pulmonary disease, or hypoventilation syndromes and patients with central sleep apnea. Residual AHI obtained from the auto-CPAP device by smart card (CPAP-AHI) was compared simultaneously with AHI from an overnight PSG on auto-CPAP (PSG-AHI) using Bland-Altman analysis and Wilcoxon signed-rank test. RESULTS: The mean AHI on the diagnostic study was 45.08 ± 1.8. During the titration, auto-CPAP markedly suppressed the respiratory events (PSG-AHI, 3.40 ± 0.20). On the other hand, CPAP-AHI was 3.35 ± 0.17. Bland-Altman analysis showed good agreement between auto-CPAP-AHI and PSG-AHI (AHI mean difference of 0.05, and the limits of agreement for the AHI were from +4.9 to -4.8). Two methods have also been compared with paired samples t test and no statistically significant difference was found (p > 0.05). CONCLUSION: Auto-CPAP can identify residual respiratory events equivalent to the use of PSG in a selected population.
