RESUMO
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
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.

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: 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 Combined pulmonary fibrosis and emphysema (CPFE) has been recognised as a phenotype of pulmonary fibrosis. We aimed to compare serum surfactant protein-A (SP-A), surfactant protein-D (SP-D) and Krebs von den Lungen-6 (KL-6) levels, functional parameters, in CPFE and IPF (idiopathic pulmonary fibrosis) patients. Methods Patients diagnosed with 'CPFE' and 'IPF' were consecutively included in 6 months as two groups. The patients with connective tissue diseases are excluded. Results In this study, 47 patients (41 males, 6 females) with CPFE (n = 21) and IPF (n = 26) with a mean age of 70.12 ± 8.75 were evaluated. CPFE patients were older, had more intense smoking history, had lower DLCO/VA, lower FVC, and worse six-minute walking distance than the IPF group (p=0.005, p=0.027, p=0.02, p<0.001, p=0.001, respectively). Serum KL-6 levels were higher in CPFE group compared to IPF group [264.70 U/ml (228.90-786) vs 233.60 (101.8-425.4), p<0.001]. Serum KL-6 levels of 245.4 U/ml and higher have 81% sensitivity and 73% specificity for the discrimination of CPFE from IPF. Conclusions Our study has shown that serum KL-6 level is a promising biomarker to differentiate CPFE from IPF. In CPFE cases respiratory and functional parameters are worse than those of pure fibrosis cases.
RESUMO
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 potential role of interleukin-6 (IL-6) in coronavirus disease 2019 (COVID-19) pneumonia provides the rationale for investigating IL-6 signaling inhibitors. OBJECTIVES: To evaluate and report treatment responses to tocilizumab (TCZ) in COVID-19 patients and compare mortality outcomes with those of standard care. MATERIAL AND METHODS: Patients hospitalized with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, diagnosed with reverse transcription polymerase chain reaction (RT-PCR) between March 2020 and April 2021, were enrolled in this single-center retrospective cohort study. Propensity score matching was performed in order to reduce confounding effects secondary to imbalances in receiving TCZ treatment. RESULTS: A total of 364 patients were included in this study. Two hundred thirty-six patients received standard care, while 128 patients were treated with TCZ in addition to standard care (26 (20.3%) patients received a dose of 400 mg intravenously once, while 102 (79.7%) patients received a total dose of 800 mg intravenously). In the propensity score-matched population, less noninvasive mechanical ventilation (p = 0.041) and mechanical ventilation support (p = 0.015), and fewer deaths (p = 0.008) were observed among the TCZ-treated patients. The multivariate adjusted Cox regression model showed a significantly higher survival rate among TCZ patients compared to controls (hazard ratio (HR): 0.157, 95% confidence interval (95% CI): 0.026-0.951; p = 0.044). The hazard ratio for mortality in the TCZ group was 0.098 (95% CI: 0.030-0.318; p = 0.0001 using log-rank test). CONCLUSIONS: This study determined that TCZ treatment in COVID-19 patients was associated with better survival, reduced need for mechanical ventilation and reduced hospital-associated mortality.

INTRODUCTION: Determining prognostic factors in patients with coronavirus disease (COVID-19) can have great impact on treatment planning and follow-up strategies. Herein, we aimed to evaluate prognostic factors and clinical scores for confirmed COVID-19 patients in a tertiary-care hospital in the Bursa region of Turkey. METHODOLOGY: Patients who had been diagnosed with COVID-19 microbiologically and/or radiologically between March and October 2020 in a tertiary-care university hospital were enrolled retrospectively. Adult patients (≥ 18 years) with a clinical spectrum of moderate, severe, or critical illness were included. The dependent variable was 30-day mortality and logistic regression analysis was used to evaluate any variables with a significant p value (< 0.05) in univariate analysis. RESULTS: A total of 257 patients were included in the study. The mortality rate (30-day) was 14.4%. In logistic regression analysis, higher scores on sequential organ failure assessment (SOFA) (p < 0.001, odds ratio (OR) = 1.86, 95% CI = 1.42-2.45) and CURB-65 pneumonia severity criteria (p = 0.001, OR = 2.60, 95% CI = 1.47-4.57) were found to be significant in predicting mortality at admission. In deceased patients, there were also significant differences between the baseline, day-3, day-7, and day-14 results of D-dimer (p = 0.01), ferritin (p = 0.042), leukocyte (p = 0.019), and neutrophil (p = 0.007) counts. CONCLUSIONS: In our study of COVID-19 patients, we found that high SOFA and CURB-65 scores on admission were associated with increased mortality. In addition, D-dimer, ferritin, leukocyte and neutrophil counts significantly increased after admission in patients who died.

INTRODUCTION: Our knowledge has gaps regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication levels and its association to severity of Coronavirus disease 2019 (COVID-19). The aim of this study was to investigate the association of SARS-CoV-2 viral load with disease severity and serum biomarkers in COVID-19 patients. METHODOLOGY: Viral load was determined via cycle threshold (Ct) values of SARS-CoV-2 real-time reverse transcriptase-polymerase chain reaction (RT-PCR) in 214 adult patients. Ct values were compared with clinical severity, biochemical and hematological biomarkers. RESULTS: Clinical course of the disease was mild (49.1%), moderate (40.2%), and severe (10.7%). Median Ct value was 28.2 (IQR: 22.2-33.8) during the first week of the disease. Ct values were lower within five days after symptom onset [lowest Ct value on the third day (median: 24, IQR: 20.6-32.3)], but they increased significantly during the second and third weeks. No association was detected between admission Ct values and disease severity. Gender, age, co-morbidity, and mortality did not differ significantly in patients with low (≤ 25) and high (> 25) Ct values. White blood cell, neutrophil, platelet, and especially lymphocyte counts, were significantly lower in patients with low Ct values. CONCLUSIONS: No definitive/clear correlation between SARS-CoV-2 viral load and severity and mortality was found in the studied COVID-19 patients. However, neutrophil, platelet, and especially lymphocyte count were significantly lower in patients with a high viral load.

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.

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: 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.

BACKGROUND: Pain has been frequently described as a clinical feature of COVID-19, and the main pain syndromes that have been associated with the acute phase of this disease so far are headache, myalgia, arthralgia, and neuropathic pain. Understanding the characteristics of pain symptoms is crucial for a better clinical approach. METHODS: Patients who were diagnosed as having COVID-19 using reverse transcription-polymerase chain reaction were included in the study. Patients were asked to complete a 51-item questionnaire via a phone interview, which included questions on demographics, acute COVID-19 symptoms, the presence of pain symptoms, and their characteristics in the acute phase of COVID-19. RESULTS: A total of 222 out of 266 patients with COVID-19 participated in the study, yielding a response rate of 83.5%. A total of 159 patients reported at least one kind of pain syndrome with a prevalence of 71.6%. Myalgia was reported in 110 (49.6%) patients, headache in 109 (49.1%), neuropathic pain symptoms in 55 (24.8%), and polyarthralgia in 30 (13.5%) patients. A total of 66 patients reported only one type of pain, 46 reported two types, 42 reported three types, and five patients reported all four types of pain. Logistic regression analysis showed that there were significant associations between these pain syndromes and a strong association was found between neuropathic pain and headache. CONCLUSION: Pain is a frequently observed symptom of mild-to-moderate COVID-19. There are significant relationships between pain syndromes in COVID-19, which may be due to a sequence of common etiologic factors. SIGNIFICANCE: This study described the main pain syndromes associated acute phase of mild-to-moderate COVID-19 and its associated features. Headaches and pain of neuropathic characteristics were prevalent in this sample.

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

OBJECTIVE: To learn about the attitudes and behaviours of patients with idiopathic pulmonary fibrosis (IPF) in relation to the difficulties experienced during the COVID-19 pandemic. DESIGN: A cross-sectional, multicentre phone call survey. SETTING: Four university hospitals in Turkey. PARTICIPANTS: The study included patients with IPF receiving antifibrotics for at least 3 months and with doctor appointment and/or scheduled routine blood analysis between March and May 2020 (the first 3 months after the official announcement of the COVID-19 pandemic in Turkey). INTERVENTIONS: Phone calls (a 5 min interview) were performed in June 2020. A questionnaire and the Hospital Anxiety-Depression Scale were applied. MAIN OUTCOME MEASURES: Patients' preferences for disease monitoring, patients' attitudes and behaviours towards IPF, drug continuation, COVID-19 diagnosis and anxiety/depression status. RESULTS: The study included 115 patients with IPF (82 male; mean age, 68.43±7.44 years). Of the patients, 73.9% had doctor appointment and 52.2% had scheduled routine blood testing; 54.5% of patients with doctor appointment self-cancelled their appointments and 53.3% of patients with scheduled routine blood testing did not undergo testing. Of the patients, 32.2% were on nintedanib and 67.8% were on pirfenidone; self-initiated drug discontinuation rate was 22.6%. The percentage of patients communicating with their physicians was 35.7%. The route of communication was by phone (34.8%). The frequency of depression and anxiety was 27.0% and 38.3%, respectively. The rates of drug discontinuation (35.1% vs 16.7%, p<0.05) and depression (37.8% vs 21.8%, p=0.07) were higher in nintedanib users than in pirfenidone users. Only two (1.7%) patients had COVID-19 diagnosis. CONCLUSIONS: During the COVID-19 pandemic, a significant proportion (>50%) of patients self-cancelled their appointments and nearly a quarter of patients discontinued their medications. Providing a documentation of the problems experienced by patients with IPF about management of the necessary requirements during the COVID-19 pandemic, this study may be a model for patients with chronic diseases.

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: 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: 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.
