RESUMO
BACKGROUND: Diagnostic accuracy of galactomannan measurements is highly variable depending on the study population, diagnostic procedures, and treatment procedures. We aimed to evaluate the effect of posaconazole prophylaxis and empiric antifungal treatment upon diagnostic accuracy of GM measurements in bronchoalveolar lavage (BAL), bronchial lavage (BL), and serum in hematological malignancy population. METHODS: Patients hospitalized in a single tertiary care center with hematologic malignancies undergoing fiberoptic bronchoscopy (FOB) with a preliminary diagnosis of IPA were retrospectively included. RESULTS: In all the study population (n = 327), AUC for BAL, BL, and serum GM were as follows: 0.731 [0.666-0.790], 0.869 [0.816-0.912], and 0.610 [0.540-0.676] with BL samples having the best diagnostic value. GM measurements in patients under posaconazole prophylaxis (n = 114) showed similar diagnostic performance. While specificity was similar between patients with and without posaconazole prophylaxis, sensitivity of GM measurements was lower in patients with prophylaxis. Analyses with patient classified according to antifungal treatment at the time of FOB procedure (n = 166) showed a decreased diagnostic accuracy in serum GM and BAL GM measurements related with the duration of treatment. However, BAL, BL, and serum GM measurements presented similar sensitivity and specificity in higher cut-off values in longer durations of antifungal treatment. CONCLUSION: Our study shows that posaconazole prophylaxis and active short-term (3 days) antifungal treatment do not significantly affect overall diagnostic performance of GM measurements in bronchoalveolar lavage and bronchial lavage samples. However, using different cut-off values for patients receiving active treatment might be suggested to increase sensitivity.

OBJECTIVE: Prognostic models aid clinical practice with decision-making on treatment and hospitalization in exacerbation of chronic obstructive lung disease (ECOPD). Although there are many studies with prognostic models, diagnostic accuracy is variable within and between models. SUBJECTS AND METHODS: We compared the prognostic performance of the BAP65 score, DECAF score, PEARL score, and modified early warning score (MEWS) in hospitalized patients with ECOPD, to estimate ventilatory support need. RESULTS: This cross-sectional study consisted of 139 patients. Patients in need of noninvasive or invasive mechanical ventilation support are grouped as ventilatory support groups (n = 54). Comparison between receiver operating characteristic curves revealed that the DECAF score is significantly superior to the PEARL score (p = 0.04) in discriminating patients in need of ventilatory support. DECAF score with a cutoff value of 1 presented the highest sensitivity and BAP65 score with a cutoff value of 2 presented the highest specificity in predicting ventilatory support need. Multivariable analysis revealed that gender played a significant role in COPD exacerbation outcome, and arterial pCO2 and RDW measurements were also predictors of ventilatory support need. Within severity indexes, only the DECAF score was independently associated with the outcome. One-point increase in DECAF score created a 1.43 times higher risk of ventilatory support need. All severity indexes showed a correlation with age, comorbidity index, and dyspnea. BAP65 and DECAF scores also showed a correlation with length of stay. CONCLUSION: Objective and practical classifications are needed by clinicians to assess prognosis and initiate treatment accordingly. DECAF score is a strong candidate among severity indexes.
RESUMO
Introduction: In a resource-constrained situation, a clinical risk stratification system can assist in identifying individuals who are at higher risk and should be tested for COVID-19. This study aims to find a predictive scoring model to estimate the COVID-19 diagnosis." Materials: Patients who applied to the emergency pandemic clinic between April 2020 and March 2021 were enrolled in this retrospective study. At admission, demographic characteristics, symptoms, comorbid diseases, chest computed tomography (CT), and laboratory findings were all recorded. Development and validation datasets were created. The scoring system was performed using the coefficients of the odds ratios obtained from the multivariable logistic regression analysis." Result: Among 1187 patients admitted to the hospital, the median age was 58 years old (22-96), and 52.7% were male. In a multivariable analysis, typical radiological findings (OR= 8.47, CI= 5.48-13.10, p< 0.001) and dyspnea (OR= 2.85, CI= 1.71-4.74, p< 0.001) were found to be the two important risk actors for COVID-19 diagnosis, followed by myalgia (OR= 1.80, CI= 1.08- 2.99, p= 0.023), cough (OR= 1.65, CI= 1.16-2.26, p= 0.006) and fatigue symptoms (OR= 1.57, CI= 1.06-2.30, p= 0.023). In our scoring system, dyspnea was scored as 2 points, cough as 1 point, fatigue as 1 point, myalgia as 1 point, and typical radiological findings were scored as 5 points. This scoring system had a sensitivity of 71% and a specificity of 76.3% for a cut-off value of >2, with a total score of 10 (p< 0.001). Conclusions: The predictive scoring system could accurately predict the diagnosis of COVID-19 infection, which gave clinicians a theoretical basis for devising immediate treatment options. An evaluation of the predictive efficacy of the scoring system necessitates a multi-center investigation.

BACKGROUND: Laboratory biomarkers to estimate the severity of coronavirus disease 2019 (COVID-19) are crucial during the pandemic since resource allocation must be carefully planned. AIMS: To evaluate the effects of basal serum total immunoglobulin E (IgE) levels and changes in inflammatory parameters on the clinical progression of patients hospitalised with COVID-19. METHODS: Patients hospitalised with confirmed COVID-19 were included in the study. Laboratory data and total IgE levels were measured on admission. Lymphocyte, eosinophil, ferritin, d-dimer and C-reactive protein parameters were recorded at baseline and on the 3rd and 14th days of hospitalisation. RESULTS: The study enrolled 202 patients, of which 102 (50.5%) were males. The average age was 50.17 ± 19.68 years. Of the COVID-19 patients, 41 (20.3%) showed clinical progression. Serum total IgE concentrations were markedly higher (172.90 (0-2124) vs 38.70 (0-912); P < 0.001) and serum eosinophil levels were significantly lower (0.015 (0-1.200) vs 0.040 (0-1.360); P = 0.002) in clinically worsened COVID-19 patients when compared with stable patients. The optimal cut-off for predicting clinical worsening was 105.2 ng/L, with 61% sensitivity, 82% specificity, 46.3% positive predictive value and 89.2% negative predictive value (area under the curve = 0.729). Multivariable analysis to define risk factors for disease progression identified higher total IgE and C-reactive protein levels as independent predictors. CONCLUSIONS: Our single-centre pilot study determined that total IgE levels may be a negative prognostic factor for clinical progression in patients hospitalised due to COVID-19 infection. Future studies are required to determine the impact of individuals' underlying immune predispositions on outcomes of COVID-19 infections.

Introduction: Noninvasive ventilation (NIV) for acute hypercapnic respiratory failure (AHRF) is an established treatment modality. Current evidence does not conclude any superiority between fixed pressure support (PS) and average volume-assured pressure support (AVAPS) modes. However, given the ability of rapid PaCO2 decline in AVAPS mode, we hypothesized that COPD patients with AHRF who did not show the desired reduction in PaCO2 with fixed-level PS-NIV might benefit from the AVAPS mode. Materials and Methods: Patients admitted to the non-ICU pulmonary ward with acute exacerbation of COPD (AECOPD) and AHRF were included consecutively in this observational study. Patients with hypercapnic respiratory failure due to obesity-hypoventilation, neurological diseases, or chest wall deformities were excluded. All patients started NIV treatment with fixed pressure support (PS) and patients who did not reach clinical and laboratory stability under PS-NIV treatment were switched to the average volume-assured pressure support (AVAPS) mode of NIV. Result: Thirty-five COPD patients with hypercapnic respiratory failure were included. Under PS-NIV treatment, 14 (40%) patients showed a 17.9 (-0.0-29.2) percent change in terms of PaCO2, meaning no improvement or worsening. Therefore, these patients were treated with AVAPS mode. Arterial PaCO2 and pH levels significantly improved after AVAPS-NIV administration. AVAPS-NIV treatment created a significantly better PaCO2 change rate than using PS-NIV [-11.4 (-22.0 - -0.5) vs 8.2 (-5.3-19.5), p= 0.02]. Independent predictors of AVAPS mode requirement were higher Charlson Comorbidity Index [OR= 1.74 (95% CI= 1.02-2.97)] and higher PaCO2 upon admission [OR= 1.18 (95% CI= 1.03-1.35)]. Thirteen (92.8%) patients reaching significant clinical stability with AVAPS-NIV were able to return to fixed-level PS-NIV and maintain acceptable PaCO2 levels. Conclusions: Our study demonstrated that patients can benefit from AVAPSNIV despite insufficient response to fixed-level PS-NIV.

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/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

Background/aim: COVID-19 patients have a wide spectrum of disease severity. Several biomarkers were evaluated as predictors for progression towards severe disease. IL-21 is a member of common γ-chain cytokine family and creates some specific effects during programming and maintenance of antiviral immunity. We aimed to assess IL-21 as a biomarker for diagnosis and outcome prediction in patients hospitalized with COVID-19. Materials and methods: Patients with a preliminary diagnosis of COVID-19 and pneumonia other than COVID-19 admitted to a tertiary care hospital were included consecutively in this comparative study. Results: The study population consisted of 51 patients with COVID-19 and 11 patients with non-COVID-19 pneumonia. Serum IL-21 concentration was markedly higher, and serum CRP concentration was significantly lower in COVID-19 patients compared to non-COVID-19 pneumonia patients. Within COVID-19 patients, 10 patients showed radiological and clinical progression. Patients with clinical worsening had lower lymphocyte count and haemoglobin. In addition to that, deteriorating patients had higher urea, LDH levels, and elevated concentration of both IL-6 and IL-21. The cut-off value of 106 ng/L for IL-21 has 80.0% sensitivity, %60.9 specificity for discriminating patients with clinical worsening. Multivariable analysis performed to define risk factors for disease progression identified IL-6 and IL-21 as independent predictors. Odds ratio for serum IL-6 concentrations ≥ 3.2 pg/mL was 8.07 (95% CI: 1.37-47.50, p = 0.04) and odds ratio for serum IL-21 concentrations ≥ 106 ng/L was 6.24 (95% CI: 1.04 37.3, p = 0.02). Conclusion: We identified specific differences in serum IL-21 between COVID-19 and non-COVID-19 pneumonia patients. Serum IL-21 measurement has promising predictive value for disease progression in COVID-19 patients. High serum IL-6 and IL-21 levels obtained upon admission are independent risk factors for clinical worsening.

INTRODUCTION: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a well-established diagnostic tool for lung cancer, sarcoidosis, and suspected metastatic extra-thoracic malignancy (ETM). Patients with primary ETM often have hypermetabolic mediastinal/hilar lymph node enlargement in the PET-scan done for initial staging or post treatment followup. We aimed to determine the diagnostic performance of EBUS-TBNA and the relationship between PET-SUV values and diagnosis of malignancy metastasis in patients with ETM. MATERIALS AND METHODS: Results of EBUS-TBNA in ETM patients with suspected MLN metastasis were retrospectively analysed (May 2016 to July 2019). Non-malign results were confirmed for surgery or clinical/radiological followup. Lymph nodes with a high FDG-uptake (SUV > 2.5, MLN) were reported as suspicious for metastasis. RESULT: Of the 588 EBUS procedures, 109 were included in the analysis. Patient' mean age was 62.5 ± 10.1 years; there were 35 men and 74 women. Primary malignancies were breast cancer in 33, gastrointestinal in 23, female genital tract in 17, head and neck in 14, genitourinary cancer in 13, malignant melanoma in 6, sarcoma in 2 and kaposi sarcoma in 1. According to EBUS-TBNA smear and cell block histopathologic evaluations, 16 patients' results (14.7%) were malignant compatible with metastasis of ETM. Among the 93 patients with non-malignant diagnosis, EBUS-TBNA revealed a granulomatous lympadenitis compatible with sarcoid reaction in 7 and tuberculosis in 2. A total of 9 patients underwent surgical procedures after EBUSTBNA, with a definitive histological diagnosis of granulomatous lymphadenitis in 2, malignancy in 5 and, reactive lymph node in 2. Overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA were 76.19% (95% CI 52.83-91.78), 100% (95% CI 95.89-100.00), 100%, 94.62% (95% CI 89.12-97.12) and 95.4%, respectively. CONCLUSIONS: EBUS-TBNA sampling has high diagnostic performance. Histopathological confirmation requirement for MLN should be kept in mind in patients with ETM, even they have negative EBUS results.

INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) exacerbations contribute to the overall severity in individual patients because they are associated with airway inflammation, pulmonary function loss, decreased quality of life and increased mortality. Although, identifying frequent exacerbator patients is important due to severe outcomes associated with frequent exacerbator phenotype in COPD patients there is no single biomarker which can differentiate this phenotype. Iron responding protein-2 (IRP2) is the protein product of IREB2 gene, which is a COPD susceptibility gene that regulates cellular iron homeostasis and has a key role in hypoxic conditions. Previous research indicates that IREB2 expression in lung tissue is associated with spirometric measurements and emphysema in COPD. In this study, our aim was to investigate whether serum IRP2 levels were associated with frequent exacerbator phenotype, to evaluate whether IRP2 levels in serum are associated with pulmonary functions and selected systemic inflammation biomarkers. MATERIALS AND METHODS: Designed as a single tertiary care center based, crosssectional study, included high risk (GOLD C, D) COPD patients who admitted to outpatient clinic consecutively between December 2015 and July 2016. RESULT: The study included 80 COPD patients. Serum IRP2 levels were negatively correlated with FEV1 ml (r= -0.25, p= 0.02) and body weight (r= -0.35, p= 0.002) but not with markers of systemic inflammation. COPD patients with at least one exacerbation history in the last year tended to have higher IRP2 levels than patients without any exacerbation [12.3 (IQR 25-75: 10.4- 17.1) vs 10.5 (IQR 25-75: 8.8-18.5), p= 0.06]. CONCLUSIONS: Serum IRP2 level is significantly correlated with FEV1 mL but not with FEV1 % predicted and cannot be used to differentiate frequent exacer bator patients. Although IREB2 gene expressions in lung tissue and bronchoalveolar lavage results have significant associations with emphysema and FEV1/FVC, FEV1 %predicted in COPD patients, our results suggests serum IRP2 level is not as promising.

INTRODUCTION: In this study, we aimed to determine the values of anthropometric measurements and rates used in the evaluation of obstructive sleep apnea syndrome (OSAS) in our country. MATERIALS AND METHODS: Twenty accredited sleep centers in thirteen provinces participated in this multicenter prospective study. OSAS symptoms and polysomnographic examination and apnea-hypopnea index (AHI) ≥ 5 cases OSAS study group; patients with AHI < 5 and STOP-Bang < 2 were included as control group. Demographic characteristics (age, sex, body mass index-BMI) and anthropometric measurements (neck, waist and hip circumference, waist/hip ratio) of the subjects were recorded. RESULT: The study included 2684 patients (81.3% OSAS) with a mean age of 50.50 ± 0.21 years from 20 centers. The cases were taken from six geographical regions of the country (Mediterranean, Eastern Anatolia, Aegean, Central Anatolia, Black Sea and Marmara Region). Demographic characteristics and anthropometric measurements; age, neck, waist, hip circumference and waist/ hip ratios and BMI characteristics when compared with the control group; when compared according to regions, age, neck, waist, hip circumference and waist/hip ratios were found to be statistically different (p< 0.001, p< 0.001, p< 0.05, respectively). When compared by sex, age, neck and hip circumference, waist/hip ratio, height, weight and BMI characteristics were statistically different (p< 0.001, respectively). Neck circumference and waist/hip ratio were respectively 42.58 ± 0.10 cm, 0.99 ± 0.002, 39.24 ± 0.16 cm, 0.93 ± 0.004 were found in women. CONCLUSIONS: The neck circumference was lower than the standard value in men, but higher in women. The waist/hip ratio was above the ideal measurements in both men and women. In this context, the determination of the country values will allow the identification of patients with the possibility of OSAS and referral to sleep centers for polysomnography.

BACKGROUND Catheter-directed therapy (CDT) for pulmonary embolism (PE) is considered as an alternative to systemic thrombolysis (ST) in patients with hemodynamically unstable acute PE who are considered at high bleeding risk for ST. We aimed to evaluate the efficacy and safety of CDT in the management of acute PE with right ventricular dysfunction (RVD). The primary outcomes were mortality, clinical success, and complications. Secondary outcomes were change in hemodynamic parameters in the first 24 hours following the procedure. MATERIAL AND METHODS Medical records of consecutive patients diagnosed as having acute massive or submassive PE with accompanying RVD treated by immediate CDT at our institution from January 2007 to January 2014 were reviewed. Patient characteristics, mortality, achievement of clinical success, and minor and major bleeding complications were analyzed in the overall study group, as well as massive vs. submassive PE subgroups. Change in hemodynamic parameters in the second, eighth, and 24th hours after the CDT procedure were also analyzed. RESULTS The study included 15 consecutive patients (M/F=10/5) with a mean age of 54.2 ± 16.6 years who underwent immediate CDT. Nine of the patients had submassive PE, and 6 had massive PE. In-hospital mortality rate was 13.3% (95% CI, 0.04-0.38). One major, but not life-threatening, bleeding episode was evident in the whole group. Hemodynamic parameters were stabilized and clinical success was achieved in 14/15 (93.3%; 95% CI, 70.2-98.8) of the patients in the first 24 hours. Notably, the hemodynamic recovery was significantly evident in the first 8 hours after the procedure. CONCLUSIONS CDT is a promising treatment option for patients with acute PE with RVD with no fatal bleeding complication. In experienced centers, CDT should be considered as a first-line treatment for patients with acute PE and RVD and contraindications for ST, with the advantage of providing early hemodynamic recovery.

BACKGROUND: Driving performance is known to be very sensitive to cognitive-psychomotor impairment. The aim of the study was to determine the relationship between obesity, risk of obstructive sleep apnoea (OSA), daytime sleepiness, history of road traffic accident (RTA) and performance on a driving simulator, among commercial drivers. METHODS: We examined commercial vehicle drivers admitted to Psycho-Technical Assessment System (PTAS), which is a computer-aided system that includes a driving simulator test and tests assessing psychomotor-cognitive skills required for driving. Risk of OSA and daytime sleepiness were assessed by the Berlin Questionnaire and the Epworth Sleepiness Scale (ESS), respectively. RESULTS: A total of 282 commercial vehicle drivers were consecutively enrolled. The age range was 29-76 years. Thirty drivers were at high risk of OSA. Median ESS of the group was 2 (0-20). Forty-seven percent of the subjects at high risk of OSA failed in early reaction time test, while 28% of the drivers with low risk of OSA failed (p = 0.03). The obese drivers failed the peripheral vision test when compared with non-obese drivers (p = 0.02). ESS was higher for drivers with a history of RTA when compared to those without RTA (p = 0.02). CONCLUSIONS: Cognitive-psychomotor functions can be impaired in obese and high risk of OSA patients. In our opinion, requiring obese and/or high risk of OSA drivers to take PTAS tests that assess driving skills and psychomotor-cognitive functions crucial to those skills would significantly improve road traffic safety, which is of considerable importance to public health.

Aspergillus infections are major causes of morbidity and mortality among immunocompromised patients. This study was designed to investigate the galactomannan assay optical density (OD) indices relative to the culture results in bronchoscopic samples obtained from neutropenic and non-neutropenic patients. Galactomannan OD indices from 1427 samples from 2005 to 2012, which were sent from 839 patients and were composed of bronchial lavage (BL = 727) and bronchoalveolar lavage fluids (BAL = 700), were retrospectively analysed. The recovery rates of Aspergillus species from these specimens were 9.4% from the combined patient group and 13.3% from the neutropenic group. Aspergillus fumigatus complex was the most frequently isolated species. The mean and median OD indices of the positive and negative culture samples are approximately 5 and 1, respectively, and 91% of all culture-positive samples have ≥1 OD index value. The receiver-operating characteristics curve analysis demonstrated that the feasibility of the Aspergillus galactomannan assay and Aspergillus galactomannan test has superior accuracy in BAL compared to BL fluids, and the test is not affected by the immune status of the patient. We suggest that the Aspergillus galactomannan test, which uses bronchoscopic material, leads to an earlier diagnosis and if the OD index is found ≥1, fungal growth can be expected.

Disseminated infections caused by members of the Fusarium fujikuroi species complex (FFSC) occur regularly in immunocompromised patients. Here, we present the first human case caused by FFSC-member Fusarium andiyazi. Fever, respiratory symptoms and abnormal computerised tomography findings developed in a 65-year-old man with acute myelogenous leukaemia who was under posaconazole prophylaxis during his remission-induction chemotherapy. During the course of infection, two consecutive blood galactomannan values were found to be positive, and two blood cultures yielded strains resembling Fusarium species, according to morphological appearance. The aetiological agent proved to be F. andiyazi based on multilocus sequence typing. The sequencing of the internal transcribed spacer region did not resolve the closely related members of the FFSC, but additional data on partial sequence of transcription elongation factor 1 alpha subunit did. A detailed morphological study confirmed the identification of F. andiyazi, which had previously only been reported as a plant pathogen affecting various food crops.

INTRODUCTION: Pneumocystis pneumonia (PCP) which is caused by Pneumocystis jirovecii is usually seen in the patients whose immune system is supressed. It is seriously seen an opportunist infection. In our study; totally 100 bronchoalveolar lavage (BAL) and bronchial washing samples collected by pulmonary disease department. Which belong to the patients in the clinics, and out patient clinic of the bronchoscopy material were evaluated. MATERIALS AND METHODS: The BAL and bronchial washing were evaluated by the help of methenamine silver stain (Gomori/Grocott), toluidine blue O stain, Wright-Giemsa stain, immun fluorescent antibody (IFA) stain, nested polymerase chain reaction (PCR). RESULTS: In the BAL and bronchial washing samples the agent couldn't be shown by the help of methenamine silver (Gomori/Grocott), toluidine blue O, Wright-Giemsa staining. In 13 patients with IFA test the cysts of P. jirovecii were determined. In 16 patients with nested PCR; the DNA of P. jirovecii were determined. In 8 patients by using PCR and IFA test P. jirovecii was determined. When the samples which had P. jirovecii were analyzed; 13 of them were BAL and 8 of them were bronchial washing. When the phenomenon groups were evaluated according to age, gender, smoking, hypertension, diabetes mellitus, chronic obstructive pulmonary disease (COPD), cerebrovascular accident (CVA), congestive cardiac failure (CCF), staying in the hospital in the last three months, using antibiotics and radiological findings; there wasn't a statistical meaningful relation between P. jirovecii positivity and these situations. When the phenomenon groups were evaluated according to PCR and IFA positivity; in IFA and PCR positive patients for immunosupressive there was a meaningful differances (p= 0.003). The positive 28.6 % of cases were immunosuppressed and the 3.8% of PCR or IFA negative cases were immunosupressed. When PCR method was compared with IFA which is called gold standard for sensitivity and specificity; sensitivity was found 61.5% and specificity was found 90.8%. IFA and PCR diagnosis test results were compatible (With McNemar test p= 0.581). CONCLUSION: Diagnostic sensitivity of staining methods for P. jirovecii in immunocompromised HIV negative patients are found to be low and it was shown that IFA and nested PCR methods have not parallel results.

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.

The aim of this study was to investigate the effects of surgical intervention for nasal pathologies on obstructive sleep apnea syndrome (OSAS) and continuous positive airway pressure (CPAP) titrations in patients with OSAS. The study was designed as a prospective case control study. Between December 2007 and June 2010, 31 patients (26 men and 5 women) who were diagnosed with OSAS with polysomnography and confirmed to have obstructive nasal pathology were enrolled in the study. The average age of the patients was 53 ± 9.6 (range 33-68 years) and the body mass index ranged from 22 to 40.6 kg/m(2) with an average of 30.3 ± 4.1. The patients were evaluated with Epworth Sleepiness Scale, OSAS Complaints Questionnaire, visual analog scale, and CPAP titration before and 3 months after nasal surgery. As three patients did not attend the control polysomnography, data analysis was performed on 28 patients. Although there was a significant improvement in the nasal passage and subjective complaints, namely, snoring frequency, apnea and daytime sleepiness, the difference between preoperative and postoperative AHI values was not statistically significant. Postoperative CPAP titration results indicated a decrease both in pressures and in AHI in comparison to preoperative values. These reductions were not statistically significant, although the decrease in CPAP pressures was close to significance (p = 0.062). Nasal pathologies should be treated in all patients with OSAS, particularly those undergoing CPAP treatment. However, patients should be counseled that favorable results might not be achieved after nasal surgery.

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.

INTRODUCTION: Eosinophilic airway inflammation is a recognized inflammatory pattern in subgroups of patients with chronic obstructive pulmonary disease (COPD). However, there are still conflicting results between various studies concerning the effect of eosinophils in COPD patients. Our aim with this study was to evaluate eosinophilic inflammation and its relation to the clinical characteristics in a group of COPD patients. METHODS: Stable COPD patients with FEV1 % predicted < 50 or with ≥ 1 exacerbation leading to hospital admission or ≥2 moderate or severe exacerbation history were consecutively enrolled from outpatient clinics. RESULTS: We included 90 male COPD patients, with a mean age of 63.3 ± 9.2. Mean FEV1 % predicted was 35.9 ± 11.3. Eosinophilic inflammation (eosinophil percentage ≥2%) was evident in 54 (60%) of the patients. Participants with eosinophilic inflammation were significantly older and had better FEV1 predicted % values. Eosinophilic COPD patients were characterized with better quality of life and fewer symptoms. COPD patients with noneosinophilic inflammation used supplemental long-term oxygen therapy (LTOT) more frequently compared to patients with eosinophilic inflammation (36.1% vs. 14.8%, p = 0.01). Eosinophilic inflammation is associated with less dyspnea severity measured by mMRC (OR: 0.542 95% CI: 0.342-0.859, p = 0.009) and less LTOT use (OR: 0.334 95% CI: 0.115-0.968, p = 0.04) regardless of age, severity of airflow limitation, and having frequent exacerbation phenotype. CONCLUSION: Our study supports the growing evidence for a potential role of eosinophilic inflammation phenotype in COPD with distinctive clinical characteristics. Eosinophilic inflammation is inversely associated with dyspnea severity measured by mMRC and LTOT use independently from age, total number of exacerbations, St. George Respiratory Questionnaire (SGRQ) total score and FEV1 % predicted.
