ABSTRACT
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.
ABSTRACT
OBJECTIVE: To assess differences in the sputum microbiota of community-acquired pneumonia (CAP) patients with either COPD or asthma, specifically focusing on a patient population in Turkey. METHODS: This retrospective study included hospitalized patients > 18 years of age with a diagnosis of pneumonia between January of 2021 and January of 2023. Participants were recruited from two hospitals, and three patient groups were considered: CAP patients with asthma, CAP patients with COPD, and CAP patients without COPD or asthma. RESULTS: A total of 246 patients with CAP were included in the study, 184 (74.8%) and 62 (25.2%) being males and females, with a mean age of 66 ± 14 years. Among the participants, 52.9% had COPD, 14.2% had asthma, and 32.9% had CAP but no COPD or asthma. Upon analysis of sputum cultures, positive sputum culture growth was observed in 52.9% of patients. The most commonly isolated microorganisms were Pseudomonas aeruginosa (n = 40), Acinetobacter baumannii (n = 20), Klebsiella pneumoniae (n = 16), and Moraxella catarrhalis (n = 8). CAP patients with COPD were more likely to have a positive sputum culture (p = 0.038), a history of antibiotic use within the past three months (p = 0.03), utilization of long-term home oxygen therapy (p < 0.001), and use of noninvasive ventilation (p = 0.001) when compared with the other patient groups. Additionally, CAP patients with COPD had a higher CURB-65 score when compared with CAP patients with asthma (p = 0.004). CONCLUSIONS: This study demonstrates that CAP patients with COPD tend to have more severe presentations, while CAP patients with asthma show varied microbial profiles, underscoring the need for patient-specific management strategies in CAP.

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.

ABSTRACT
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.

Idiopathic pulmonary fibrosis (IPF) is the most common progressive interstitial disease of unknown etiology. The course of disease is not possible to predict. Frequent monitoring using multiple assessments is important to evaluate disease progression. Currently, there is no consensus on how progression should be defined. Nintedanib and pirfenidone slow the progression of IPF, but the disease can progress even under anti-fibrotic treatment. The goal of this review is to examine and summarize the current data about IPF progression in patients who were on anti-fibrotic treatment. Also, we outline the limitations of the tests used for disease progression.
ABSTRACT
BACKGROUND: Idiopathic pulmonary fibrosis (IPF) predominantly affects people over the age of 60 years and its incidence increases with age. Limited data is available on the use of antifibrotics in the elderly IPF population. We aimed to examine the tolerability and safety of antifibrotics (pirfenidone, nintedanib) in elderly patients with IPF in a real-world setting. METHODS: Medical records of 284 elderly (≥75 years) and 446 non-elderly IPF patients (<75 years) were retrospectively analyzed in this multi-center study. Patient characteristics, treatments, adverse events (AEs), tolerability, hospitalizations, exacerbations, and mortality were compared between the elderly and non-elderly group. RESULTS: In the elderly group, the mean age was 79 years and the mean antifibrotic treatment duration was 26.1 months. The most commonly reported AEs were weight loss, loss of appetite and nausea. Elderly IPF patients had a significantly higher incidence of AEs (62.9% vs. 55.1%, p = 0.039) and dose reductions (27.4% vs. 18.1%, p = 0.003) than the non-elderly did, but the rate of discontinuation of antifibrotics was not different between groups (13% vs. 10.8%, p = 0.352). In addition, the severity of the disease, frequency of hospitalizations, exacerbations, and mortality rates were higher in elderly patients. CONCLUSION: The present study showed that elderly IPF patients experienced significantly increased AEs and dose reductions due to antifibrotic use, while the discontinuation rates of the drugs were similar to those of drugs used by non-elderly patients.

Background: To determine the contribution to diagnostic rates of the evaluation of the sonographic characteristics of lymph nodes with EBUS together with vascularity. Methods: In the present study, patients who underwent the Endobronchial ultrasound (EBUS) procedure were evaluated retrospectively. Patients were classified as benign or malignant by using the sonographic features of EBUS. EBUS-Transbronchial Needle Aspiration (TBNA) confirmed histopathologically with lymph node dissection or in cases where no disease progression was observed clinically or radiologically in at least 6 months of follow-up. Malignant lymph node diagnosis was based on histological examination. Results: Evaluation was made of 165 patients comprising 122 (73.9%) males and 43 (26.1%) females with a mean age of 62.0 ± 10.7 years. Malignant disease was diagnosed in 89 (53.9%) cases and benign disease in 76 (46.1%) cases. The success level of the model was seen to be approximately 87%. The Nagelkerke R2 value was calculated as 0.401. The probability of malignancy increased 3.86-fold (95% CI: 2.61-5.11) in lesions of diameter ≥20 mm compared to lesions <20 mm, 2.58-fold (95% CI: 1.48-3.68) in lesions not determined with central hilar structure (CHS) compared to those determined with CHS, 6.85-fold (95% CI: 4.67-9.03) in lymph nodes observed with necrosis compared to those without necrosis, and 1.51-fold (95% CI: 0.41-2.61) in lymph nodes with a vascular pattern (VP) score of 2-3 compared to those with a VP score of 0-1. Conclusion: Visualization of coagulation necrosis with EBUS-B mode and the determination of VP 2-3 in power Doppler mode were seen to be the most important criteria of malignancy.
ABSTRACT
Background: Tuberculin skin test (TST) has played an essential in the diagnosis of latent tuberculosis infection (LTBI) for nearly a century. Objective: This study aimed to investigate the general characteristics of patients tested with TST in a tertiary hospital within two years. Methods: All patients who were evaluated to screen for tuberculosis and received a TST were included. The Mantoux method was used for TST administration. Results: A total of 661 patients, 345 (52.2%) men and 316 (47.8%) women, with a mean age of 43.0 ±15.9 years, were included in the study. Accordingly, TST was performed prior to anti-TNF biological agent therapy for 50% (331) of the participants, for LTBI screening before solid organ and/or hematological stem cell transplantation for 20.4% (135), for screening following contact with tuberculosis for 25.1% (166), for screening of healthcare professionals for 1.1% (7), and medical report for 3.3% (22). 2.7% of the patients who took TST were diagnosed with active tuberculosis (14 with pulmonary tuberculosis and 4 with extrapulmonary tuberculosis). QuantiFERON-TB Gold (QFT) test was performed in 332 (50.2%) patients with anergic TST results. According to TST and QFT test results, 28.3% (187) of the patients were started on tuberculosis prophylaxis. Conclusion: While TST is most performed for LTBI screening prior to biological agent therapy, almost one-fourth of patients taking TST require tuberculosis prophylaxis. On the other hand, about half of the patients require an additional QFT test.
Antecedentes: La prueba de la tuberculina ha jugado un papel fundamental en el diagnóstico de la infección latente por tuberculosis durante casi un siglo. Objetivo: Investigar las características generales de los pacientes a los que se les realizó la prueba de tuberculina en un hospital de tercer nivel. Métodos: Se incluyeron todos los pacientes que fueron incluidos en un tamizaje de tuberculosis mediante la prueba de tuberculina. Se utilizó el método de Mantoux para la administración de esta prueba. Resultados: Se incluyeron en el estudio un total de 661 pacientes, 345 (52.2%) hombres y 316 (47.8%) mujeres, con una edad media de 43.0 ±15.9 años. La prueba de tuberculina se realizó en el 50% (331) de los participantes, antes de la terapia con agentes biológicos anti-TNF; En el 20.4% (135) se hizo la prueba antes del trasplante de órganos sólidos y/o células madre hematológicas; para el 25.1% (166) se realizó tras contacto con la tuberculosis, el 1.1% (7) para tamizaje de los profesionales sanitarios y con informe médico para el 3.3% (22). El 2.7% de los pacientes que se realizaron la prueba de tuberculina fueron diagnosticados con tuberculosis activa (14 pulmonar y 4 extrapulmonar). La prueba QuantiFERON-TB Gold (QFT) se realizó en 332 (50.2 %) pacientes con resultados anérgicos para tuberculina. Según los resultados de las pruebas de tuberculina y QFT, el 28.3% (187) de los pacientes iniciaron profilaxis antituberculosa. Conclusión: Si bien la prueba de tuberculina se realiza comúnmente para la detección de tuberculosis latente antes de la terapia con agentes biológicos, casi una cuarta parte de los pacientes que se les hizo la prueba de tuberculina requieren profilaxis para tuberculosis. Por otro lado, aproximadamente la mitad de los pacientes requieren una prueba QFT adicional.
ABSTRACT
Background: Direct oral anticoagulants (DOACs) have been used in acute pulmonary thromboembolism as an alternative to warfarin due to drug interactions, narrow therapeutic range, and necessary close International Normalized Ratio (INR) monitoring. Phase 3 study results have reported that these drugs are at least as effective as warfarin and beneficial in terms of bleeding; however, studies that present up-to-date life data are necessary. Aims: To evaluate the frequency of using DOACs, which are prescribed with a limited number of indications in our country, and real-life data results. Study Design: Cross-sectional study. Methods: This cross-sectional survey collected the clinical data (history, current treatment, treatment duration, etc.) of patients with pulmonary thromboembolism and who applied to the physician for follow-up between October 15, 2019, and March 15, 2020. The researchers kept the patient records sequentially. Results: Data from 836 patients with acute pulmonary thromboembolism from 25 centers were collected, and DOAC was used in 320 (38.5%) of them. The most preferred DOAC was rivaroxaban (n = 294, 91.9%). DOAC was mostly preferred because it could not provide an effective INR level with warfarin (n=133, 41.6%). Bleeding was observed in 13 (4%) patients. Conclusion: The use of direct oral anticoagulants is becoming almost as widespread as conventional therapy. Real-life data results are important for their contribution to clinical practice.

BACKGROUND: There are few data on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (COVID-19) infection in patients with idiopathic pulmonary fibrosis (IPF). The objective of this study is to describe the characteristics and outcomes of IPF patients confirmed COVID-19 infection. METHODS: In this retrospective, multi-center, cohort study, patients from 4 hospital medical records with known IPF and a COVID-19 diagnosis were identified. Demographic and clinical outcome data were abstracted through a review of electronic medical records. RESULTS: Records for 46 patients with IPF and COVID-19 were abstracted. The mean age was 65±10 years. The most common symptom was dyspnea, followed by fever and cough. Ground-glass opacities (n = 35, 83.3%) and consolidations (n = 11, 26.1%) were the main imaging features of the disease in thorax computed tomography (CT). Twenty-four patients (52.1%) required hospitalization. Among the hospitalized patients, 16 (66.6%) were admitted to the intensive care unit (ICU), and 10 (41.6%) underwent invasive mechanical ventilation. Thirteen patients (28.2%) died of COVID-19 complications. Mortality rate was significantly associated with lower DLCO/VA, long term oxygen therapy and consolidation finding on CT of thorax (p<0.05). On multivariable analysis, neither factor was associated with hospitalization or mortality. CONCLUSIONS: IPF patients represent a vulnerable population for COVID-19, according to the high rate of hospitalization, ICU requirement, and mortality rate. Measures to minimize the risk of COVID-19 infection remain key to protect IPF patients.

A 76-year-old female received a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine (CoronaVac, Sinovac®, Beijing, China) and subsequently experienced chest discomfort. A computed tomography performed 1 day after vaccination showed multiple infiltrations in both lungs and ground-glass shadows in both lung fields. Her fingertip oxygen saturation was 81% and there was widespread wheezing on physical examination. Based on these findings, the patient was hospitalized with a preliminary diagnosis of drug-induced pneumonitis and acute asthma exacerbation due to a SARS-CoV-2 vaccine. During her hospitalization, 40 mg/d systemic steroid, 4 times a day salbutamol nebulized, 2 L/min inhaled oxygen therapy and 400 mg/d moxifloxacin intravenous were administered for 5 days. One month later, the thorax computed tomography scan revealed that the previous findings were almost completely regressed.

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.

BACKGROUND: Lung cancer is both the most common seen malignity and cause of cancer-related deaths worldwide. Adenosine deaminase (ADA) is a hydrolytic enzyme that catalyses the conversion of adenosine to inosine in the purine metabolism pathway. Studies examining ADA levels in bronchoalveolar lavage (BAL) fluids of patients with lung malignancy are very limited in the literature. Our aim examine the clinical significance of ADA levels in BAL fluids of patients with lung malignancy. METHODS: A total of 89 patients undergoing fiberoptic bronchoscopy (FOB) with different indications from December 2017 to December 2018 were included in this study. The patients were divided into two groups as malignancy and non-malignancy groups. Demographic, laboratory data and ADA levels in bronchoalveolar lavage (BAL) were compared between the two groups. In addition, ADA levels in BAL were compared among the histopathological subtypes of patients in the malignant group. RESULTS: The mean age of the patients was 58.2 ± 14.5 years with 86% of male gender. ADA enzyme levels were statistically higher in the malignant patient group compared with the non-malignant group (37.2 [17.6-71] vs 17.1 [9-35.3], P < .001). When the patients in the malignant group were compared in terms of ADA levels according to their histopathological types, a statistically significant difference was obtained in small cell carcinoma patients (49 [12.5-75.3], P = .005). CONCLUSION: ADA levels in BAL may be a diagnostic biomarker in lung malignancies. In patients where a biopsy cannot be taken or histopathological typing cannot be performed because of tissue insufficiency, ADA levels in BAL can be an auxiliary parameter in making malignancy / histopathological diagnosis accompanied by radiological and clinical findings.

The COVID-19 pandemic has brought countries' health services into sharp focus. It was drawn to our group's attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.

World Health Organization has declared coronavirus disease-19 (COVID-19) as a pandemic. Although there are studies about this novel virus, our knowledge is still limited. There is limited information about its diagnosis, treatment and prognosis. We aimed to investigate the effect of methemoglobin and carboxyhemoglobin levels on the prognosis of COVID-19. In this observational study, patients who were diagnosed with COVID-19 during March 1-April 31, 2020 in a secondary-level state hospital in Turkey were included in the study. COVID-19 diagnosis was confirmed with reverse transcription polymerase chain reaction method, with nasal, oral or sputum specimens. During the period this study was performed, 3075 patients were tested for COVID-19 and 573 of them were hospitalized. Among the hospitalised patients, 23.2% (133) of them had a positive polymerase chain reaction result for COVID-19. A total of 125 patients, 66 (52.8%) males and 59 (47.2%) females, with an average age of 50.2 ± 19.8 years, were included in the study. The most common findings in chest radiogram were ground-glass areas and consolidations, while one-third of the patients had a normal chest radiogram. Computed thorax tomography was performed for 77.6% (97/125) of the patients. The 24.7% of computed tomographies (24/97) did not reveal any pathological findings, and the most common findings were ground-glass appearance and consolidation. Those who needed intensive care had statistically significantly lower platelet count (P = 0.011) and higher lactate dehydrogenase levels (P < 0.001). No statistically significant difference was found in carboxyhemoglobin (P = 0.395) and methemoglobin (P = 1.000) levels. We found that carboxyhemoglobin and methemoglobin levels had no effect on COVID-19 prognosis, but low platelet level played a role in predicting COVID-19 prognosis. This study was approved by the Ethical Committee of Harran University Faculty of Medicine on May 11, 2020 with approval No. 09.

BACKGROUND: The relationship between vitamin D and asthma is still under investigation. We aimed to evaluate the association between serum vitamin D levels and clinical characteristics of asthma, and the impact of vitamin D deficiency on the clinical manifestations, as them being the issues of debate. METHODS: Patients who were admitted to the outpatient clinics of Chest Diseases Department of Akdeniz University Hospital between January 2014 and December 2014, have been diagnosed as asthma according to the GINA 2014 guidelines were included in this study. Subjects with COPD, bronchiectasis, pneumonia or tuberculosis were excluded. Asthma exacerbation was defined, according to the GINA guidelines, as episodes of progressive shortness of breath, cough, wheezing or chest tightness accompanied by PFT abnormalities such as decreased PEF or FEV1. RESULTS: A total of 158 patients with mean age of 48.8 years were included in the study. Twenty-seven (17.08%) of the patients demonstrated sufficient vitamin D serum levels (i.e. ≥30 ng/mL), while the remaining 131 (82.92%) patients had vitamin D insufficiency (i.e. <30 ng/mL). When these two patient groups (vitamin D sufficient vs. insufficient) were compared with each other, the patients showing sufficient levels of vitamin D were found to reveal significantly higher FEV1 (L) and FVC (L) values. When the patients were grouped into 4 categories with regard to their serum vitamin D measurements, hospitalization numbers were found to significantly increase with decreasing vitamin D levels. CONCLUSION: Vitamin D deficiency was significantly associated with poorer pulmonary functions and higher hospitalization numbers.
ABSTRACT
BACKGROUND: This is a retrospective study to investigate the effects of Carboxyhemoglobin (COHb) and Methemoglobin (MetHb) levels in the diagnosis and prognosis of Pulmonary Thromboembolism (PTE). MATERIALS AND METHODS: Cases that were confirmed with PTE diagnosis using CT Pulmonary Angiography (CTPA) or Ventilation/Perfusion Scintigraphy were accepted as pulmonary embolism. And patients which were excluded using the same methods were accepted as the control group. Patients with carbon monoxide poisoning, Chronic Obstructive Pulmonary Disease (COPD), sepsis, pneumonia, asthma, idiopathic pulmonary fibrosis, bronchiectasis, decompensated cardiac failure or those who used drugs that cause methemoglobinemia (sulphanomides, dapson, phenacetin, primacine, benzocaine) were not included in the study. RESULTS: In our study, 462 patients were examined with an initial PTE diagnosis. Among these patients, 107 patients who met the inclusion criteria were included in the study. The mean age of all patients was 56.44 ±17.3 years (21-86) and the mean age of patients with PTE diagnosis was 55.3 years and the mean age of excluded patients was 59 years (p:0.27). When the blood gas parameters of both groups were compared, COHb levels in the groups with PTE diagnosis were statistically significantly higher (p=0.001), and the PO2 levels in the group excluded for PTE diagnosis were statistically significantly higher (p=0.028). In our study, six of our patients (8.1%) died in the early stages because of PTE. CONCLUSION: In our study, COHb level was found to be statistically significant in the group with PTE. However, this value was not higher than the normal COHb level in the blood. We found that MetHb and COHb levels were not statistically significant in the prognosis of PTE.
ABSTRACT
BACKGROUND: Asthma is one of the most common chronic diseases and may cause psychiatric disorders affecting the patients' quality of life. In our study, we evaluated the effect of omalizumab treatment on anxiety disorder and depression using Beck Depression Scale (BDS) and State Trait Anxiety Inventory (STAI). METHODS: Anxiety level was determined with STAI, whereas depression level was evaluated by BDS. Patients were asked to mark the questionnaires to reflect their emotional state before treatment, and to reflect their emotions they are feeding in the current moment. All patients receiving omalizumab treatment were included in the study. Patients with known neuropsychiatric disorder were excluded from the study. RESULTS: A total of 20 patients with mean age of 50.25 years were enrolled in the study. Gender distribution was: 5(25%) male patients and 15(75%) female patients. All patients with severe asthma received omalizumab treatment. The omalizumab treatment period was shown for mean 17.6 months (2-40 months). In anxiety scales, there was statistically significant difference compared with pretreatment and posttreatment periods. Depression (moderate to severe) was present in 12 patients before omalizumab treatment and 3 patients after omalizumab treatment. CONCLUSIONS: Uncontrolled asthma as a chronic disorder can cause depressive symptoms and worsen quality of life. We believe by controlling asthma, quality of life will improvein such patients. In appropriate indication, omalizumab can improve depression and anxiety in asthma patients.
