To evaluate the utility of neutrophil–lymphocyte ratio (NLR) determined at initial diagnosis in predicting advanced disease stage and discriminating between active and stable disease in sarcoidosis. A total of 465 patients with biopsy-proven sarcoidosis (age: 47 years, 70.5% females) were included in this retrospective cross-sectional study. Data on patient demographics, sarcoidosis stage, clinical status (stable and active), anti-inflammatory treatments, complete blood count, and inflammatory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) and platelet/mean platelet volume (MPV) ratio were recorded. NLR values were compared by subgrouping the patients according to the stage of sarcoidosis and clinical status, while the receiver operating characteristics (ROC) curve was plotted to determine the role of NLR in the identification of disease activity with the calculation of area under the curve (AUC) and cutoff value via ROC analysis. Overall, active, and stable disease was evident in 36 (7.8%) and 427 (92.2%) patients, respectively. Median NLR values were significantly higher in patients with active disease compared with stable disease (3.31 (2.34–4.31) vs. 2.29 (1.67–3.23), p = 0.005). Advanced sarcoidosis stage was associated with significantly higher NLR values at stages 0, I, II, III and IV, respectively (p = 0.001). ROC analysis revealed an NLR cutoff value of ≥2.39 (AUC (95% CI): 0.70 (0.62–0.79), p < 0.001) to discriminate between active and stable clinic with a sensitivity of 72.0% and specificity of 52.0%. The significantly higher percentage of patients with active vs. stable disease had NLR values ≥2.39 (74.0 vs. 47.0%, p = 0.002). Our findings indicate the potential utility of on-admission NLR values to predict the risk of advanced disease stage and to discriminate between active and stable disease in sarcoidosis. Measured via a simple, readily available, and low-cost test, NLR seems to be a valuable marker for monitoring disease activity and progression.

Aim: To determine the frequency of the development of anxiety and depression in asthma patients who attended an outpatient clinic during the COVID-19 pandemic, whether these rates were higher than those of the healthy population, and whether there is a possible relationship between asthma control levels, anxiety, and depression. Method: A total of 112 patients with asthma and 81controls, whose mean ages and genders were matched, were included in the study. Demographic data of the two groups and general information about their asthmatic conditions were recorded. Asthma control tests (ACTs) were performed to determine the level of asthma control. The Beck Depression Inventory and Beck Anxiety Inventory were administered to the asthma patients and controls. The groups were compared in terms of their Beck depression and anxiety scores and asthma control. We investigated whether there is a relationship between asthma control level and anxiety and depression scores. Results: Of the asthma patients, 78.6% were found to have anxiety, and 48.2% reported depression, while 32.1% anxiety and 12.3% depression were found in the control group. Depression and anxiety scores were significantly higher in asthma patients than in the control group. It was observed that 59% of the patients had very poorly controlled asthma, and as the ACT levels of the patients worsened, depression and anxiety scores increased. Conclusions: To reduce the frequency of anxiety and depression in asthma patients, it is essential to provide accurate information about COVID-19 and to effectively control asthma. Therefore, asthma patients should be informed about COVID-19 and advised to engage in regular outpatient examinations.

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.

Background: Granulomatous inflammation is found in a wide range of diseases, and most commonly associated with sarcoidosis and tuberculosis. Granulomas are pathologically classified into two main groups; necrotic and non-necrotic. Objectives: The aim of this study was to evaluate the radiological, laboratory, and pathological findings of a large patient population with granuloma in biopsy samples, to determine the final diagnostic distribution. Methods: This study was designed as a retrospective, descriptive, observational, cross-sectional study. It was conducted in patients with granulomatous inflammation detected in lung, pleural, mediastinal, hilar, and/or peripheral lymph node biopsies. Demographic information, radiological, microbiological, and laboratory results of the patients were obtained via the information processing system of the hospital. The diagnoses recorded were re-evaluated by at least two experienced clinicians and the final diagnosis distributions were made. Results: A total of 392 patients were included in the study. Non-necrotizing inflammation was detected in 268 patients, and necrotizing granulomatous inflammation was found in 124 patients. The most common cause of non-necrotizing inflammation was sarcoidosis, and tuberculosis in the case of necrotizing inflammation. A total of 77.2% of sarcoidosis patients had non-necrotizing inflammation and 54.3% of the tuberculosis patients had necrotizing inflammation. In the diagnosis distribution of granulomatous inflammation sarcoidosis, mycobacterium infections (especially tuberculosis), sarcoid reaction due to malignancy, pneumoconiosis, granulomatosis with polyangiitis and hypersensitivity pneumonitis were detected, respectively. A total of 392 patients were diagnosed with 13 different diseases. In 15 patients (3.8%) no specific diagnosis could be made. Conclusions: The diagnosis of granulomatous inflammation detected in biopsy samples is common for clinicians and a differential diagnosis is difficult in many cases. A patient’s clinical findings, laboratory results, and radiological appearance, should be evaluated in detail and a final diagnosis only made following a multidisciplinary discussion. The presence of necrosis in tissue samples alone is not a reliable finding for a final diagnosis.

The aim of the study is to develop a scale that could assess illness perception and reaction in patients with COPD. The study was conducted in the patients who were admitted in the pulmonary disease departments of a public and a private hospital. The study included 271 COPD patients. The COPD Perception and Reaction Scale consisting of fifty-four items was prepared as Likert type 5 rating scale. In the validity phase of the study, expert judgments were obtained for content validity then explanatory and confirmatory factor analysis were used. The reliability of the scale in terms of internal consistency was tested with the Cronbach Alpha coefficient. According to the results of the exploratory factor analysis, COPD Perception and Reaction Scale consists of 3 sub-dimensions and 23 items. Factors are named as behavioral reaction, emotional reaction and spiritual reaction. According to confirmatory factor analysis, the goodness-of-fit indices obtained (x2 / df = (676,47 / 227) 2.98 and RMSEA = .056, NFI = .80, CFI = .96, NFI = .91 and AGFI = .85) suggests that the recommended model for the scale is acceptable. The Cronbach’s alpha coefficient was found as .74, and for the sub-dimensions Cronbach’s alpha values were calculated as .87 for “emotional reaction”, .76 for “behavioral reaction” and .79 for “spiritual reaction”. The 23-item form of the COPD Illness Perception and Reaction Scale was demonstrated to be a valid and reliable scale for determining the perception and the reaction towards illness in COPD patients in Turkey.

A first case of endobronchial mucosal neuroma with sarcoidosis is hereby reported. A 67-year female patient, who was diagnosed as sarcoidosis previously, was admitted to our hospital with symptoms of dyspnea, chest pain and fatigue. Middle lobe atelectasis and endobronchial lesion were observed in thorax computed tomography (CT). Fiberoptic bronchoscopy revealed polypoid lesions and histopathological examination of biopsy material showed clustered nerve bundles consistent with mucosal neuroma and non-necrotising granulomas consistent with sarcoidosis. Mucosal neuromas are pathognomonic features of multiple endocrine neoplasia (MEN) type 2B. But other components of MEN type 2B such as medullary tyroid carcinoma or pheochromocytoma were not detected in our patient. Hence, a diagnosis of solitary mucosal neuroma and sarcoidosis in the bronchi was made.

Although most COPD exacerbations are neutrophilic, approximately 10%–25% of exacerbations are eosinophilic.Aim: We aimed to evaluate mortality and outcomes of eosinophilic and non-eosinophilic COPD exacerbations and identify new biomarkers that predict survival.Methods: A retrospective observational cohort study was carried out in a tertiary teaching hospital from January 1, 2014 to November 1, 2014. All COPD patients hospitalized with exacerbations were enrolled in the study at their initial hospitalization and followed-up for 6months after discharge. Electronic data were collected from the hospital database. Subjects’ characteristics, hemogram parameters, CRP levels, neutrophil-to-lymphocyte ratio (NLR), platelet-to-mean platelet volume ratio on admission and discharge, length of hospital stay (days), readmissions, and mortality were recorded. Patients were grouped according to peripheral blood eosinophil (PBE) levels: Group 1, >2% PBE, eosinophilic; Group 2, non-eosinophilic ≤2%. Patient survival after hospital discharge was evaluated by Kaplan–Meier survival analysis.Results: A total of 1,704 patients hospitalized with COPD exacerbation were included. Approximately 20% were classified as eosinophilic. Six-month mortality was similar in eosinophilic and non-eosinophilic groups (14.2% and 15.2%, respectively); however, the hospital stay length and readmission rate were longer and higher in the non-eosinophilic group (P
