Can the ADO Index Be Used as a Predictor of Mortality from COVID-19 in Patients with COPD?

Background: Several studies have shown that the risk of mortality due to COVID-19 is high in patients with COPD. However, evidence on factors predicting mortality is limited. Research Question: Are there any useful markers to predict mortality in COVID-19 patients with COPD?. Study Design and Methods: A total of 689 patients were included in this study from the COPET study, a national multicenter observational study investigating COPD phenotypes consisting of patients who were followed up with a spirometry-confirmed COPD diagnosis. Patients were also retrospectively examined in terms of COVID-19 and their outcomes. Results: Among the study patients, 105 were diagnosed with PCR-positive COVID-19, and 19 of them died. Body mass index (p= 0.01) and ADO (age, dyspnoea, airflow obstruction) index (p= 0.01) were higher, whereas predicted FEV1 (p< 0.001) and eosinophil count (p= 0.003) were lower in patients who died of COVID-19. Each 0.755 unit increase in the ADO index increased the risk of death by 2.12 times, and each 0.007 unit increase in the eosinophil count decreased the risk of death by 1.007 times. The optimum cut-off ADO score of 3.5 was diagnostic with 94% sensitivity and 40% specificity in predicting mortality. Interpretation: Our study suggested that the ADO index recorded in the stable period in patients with COPD makes a modest contribution to the prediction of mortality due to COVID-19. Further studies are needed to validate the use of the ADO index in estimating mortality in both COVID-19 and other viral respiratory infections in patients with COPD.

The association between total cholesterol and cognitive impairment in chronic obstructive pulmonary disease patients.

AIM: Chronic obstructive pulmonary disease (COPD) is primarily a respiratory system disorder associated with extrapulmonary conditions. Cognitive impairment (CoI) is very common among COPD patients This study sought to investigate the association between CoI and clinical parameters, inflammatory markers and lipid profiles in a COPD patient population. METHODS: The study population included 111 stable COPD patients. COPD was diagnosed according to Global Initiative for Chronic Obstructive Lung Disease guideline. Total complete blood count test and biochemical measurements including lipid profile were performed. Afterwards, all patients underwent neuropsychological assessment including Hospital Anxiety and Depression Scale (HADS), Pittsburgh Sleep Quality Index and Montreal Cognitive Assessment (MoCA) tests. RESULTS: The patients were categorized into two groups according to their MoCA test score: MoCA score ≤ 21 (CoI) (n = 69) and MoCA score > 21 (normal cognition) (n = 42). Total cholesterol (TC) levels were significantly lower in patients with CoI compared to patients with normal cognition. Inflammation related parameters including C-reactive protein were similar among groups. Multivariate logistic regression analysis yielded education, HADS score and TC (OR:1.02, 95% CI:1.00-1.04, p = 0.025) as independent predictors of MoCA score. CONCLUSION: TC independently associates with CoI in COPD patients. There is comparable inflammatory status in COPD patients with CoI compared to COPD patients with normal cognition.

Chronic obstructive pulmonary disease phenotypes in Turkey: the COPET study-a national, multicenter cross-sectional observational study.

BACKGROUND: While mortality rates decrease in many chronic diseases, it continues to increase in COPD. This situation has led to the need to develop new approaches such as phenotypes in the management of COPD. We aimed to investigate the distribution, characteristics and treatment preference of COPD phenotypes in Turkey. METHODS: The study was designed as a national, multicenter, observational and cross-sectional. A total of 1141 stable COPD patients were included in the analysis. RESULTS: The phenotype distribution was as follows: 55.7% nonexacerbators (NON-AE), 25.6% frequent exacerbators without chronic bronchitis (AE NON-CB), 13.9% frequent exacerbators with chronic bronchitis (AE-CB), and 4.8% with asthma and COPD overlap (ACO). The FEV1 values were significantly higher in the ACO and NON-AE than in the AE-CB and AE NON-CB (p < 0.001). The symptom scores, ADO (age, dyspnoea and FEV1 ) index and the rates of exacerbations were significantly higher in the AE-CB and AE NON-CB phenotypes than in the ACO and NON-AE phenotypes (p < 0.001). Treatment preference in patients with COPD was statistically different among the phenotypes (p < 0.001). Subgroup analysis was performed in terms of emphysema, chronic bronchitis and ACO phenotypes of 1107 patients who had thoracic computed tomography. A total of 202 patients had more than one phenotypic trait, and 149 patients showed no features of a specific phenotype. DISCUSSION: Most of the phenotype models have tried to classify the patient into a certain phenotype so far. However, we observed that some of the patients with COPD had two or more phenotypes together. Therefore, rather than determining which phenotype the patients are classified in, searching for the phenotypic traits of each patient may enable more effective and individualized treatment.

The Effect of Serum Electrolyte Disturbances and Uric Acid Level on the Mortality of Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease.

OBJECTIVES: The aim of the study was to determine the prevalence of electrolyte and uric acid disturbances and their effects on mortality in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). MATERIALS AND METHODS: This study included all consecutive AECOPD patients who were managed at our Chest Diseases department between May 2017 and December 2017. Medical records of all the subjects were reviewed, and data were collected retrospectively. Eighty-one patients with AECOPD and 103 subjects in the control group were enrolled retrospectively. The association between the COPD and control groups and biochemical parameters in patients with and without long-term oxygen therapy and noninvasive mechanical ventilation treatment in COPD patients were compared with mortality. RESULTS: Serum magnesium, phosphorus, potassium, sodium, and calcium (Ca levels were higher in control subjects than in COPD patients (p=0.006, p=0.015, and p<0.001, respectively). While serum levels of Ca and K were significantly lower and serum level of uric acid was higher in deceased COPD patients than in alive AECOPD patients (p=0.023, p=0.001, and p=0.033, respectively), serum levels of Mg, P, and other biochemical parameters were similar. CONCLUSION: Serum Ca, K, and uric acid levels during the exacerbation period were significant predictors of mortality in COPD patients. In conclusion, the levels of these parameters should be measured and corrected during AECOPD treatment to decrease mortality.

Does Nutritional Risk Screening 2002 Correlate with the Dyspnea Status of Patients with GOLD Stage C-D Chronic Obstructive Pulmonary Disease?

OBJECTIVES: Dyspnea is a prominent symptom of chronic obstructive pulmonary disease (COPD). Patients with Global Initiative for Obstructive Lung Disease (GOLD) Stage C-D often complain of dyspnea, but the relationship between their level of dyspnea and their nutritional status has not yet been established. The aim of this study was to evaluate the dyspnea levels and nutritional status ofstable COPD patients in the out patient clinic. MATERIALS AND METHODS: Medical records including the Modified Medical Research Council (mMRC) Dyspnea Scale and the nutritional status of 41 patients were investigated in the study. The meanage of patients was 71.7±9.2 years. The Nutritional Risk Screening 2002 (NRS-2002) tool, body mass index (BMI), and mid-upper arm circumference were used to evaluate their nutritional status. We used correlation analysis to display the relationship between NRS-2002 score and MRC, COPD stage, and biochemical and anthropometric parameters indicating the nutritional status of patients. RESULTS: Out of the 41 COPD patients 87.8% (36) enrolled in the study were men and 12.2% (5) were women. The GOLD stages of the patients were 29.3% of patients with stage C and 70.7% with stage D. The risk of malnutrition (NRS ≥3) was detected in 48.8% of the patients, whereas 51.2% of patients (NRS<3) were risk-free. The mid-upper arm circumference of at risk patients was lower (25.6±3.2 vs 29.9±2.7 cm, p=0.032). The NRS-2002 score had a positive correlation with mMRC records (r=0.351, p=0.024). There was a statistically significant negative correlation between the NRS-2002 score and the mid-upper arm circumference (r=0.604, p<0.0001). Also, there was a negative correlation between BMI and mid-upper arm circumference (r=0.699, p<0.0001). CONCLUSION: The risk of malnutrition was common in stable COPD patients at the outpatient clinic, which seemed to adversely affect their dyspnea level. Therefore, while planning the treatment of COPD patients, evaluating their nutritional status and taking precautions accordingly contribute to the shortness of breath which is one of the most significant symptoms of the disease.

Evaluating Stable Chronic Obstructive Pulmonary Disease by Ultrasound.

BACKGROUND AND AIM: The purpose of the study was to evaluate the relationship between COPD severity and the diaphragmatic function measured by point-of-care US in patients with stable COPD. METHOD: A total of 61 patients with COPD and 40 healthy subjects who had been admitted to Ufuk University Hospital between December 2018 and May 2019 were enrolled. Point-of-care US was performed, and lung silhouette and anterior, right, and left hemidiaphragm method in M-mode were used to evaluate the diaphragm. RESULTS: The point-of-care US measurements, lung silhouette method right (Lung Sil R), lung silhouette method left (Lung Sil L), right hemidiaphragm US method in B-mode (Ant B-Mode R), and right hemidiaphragm US method in M-mode (Ant M-Mode R), were significantly different among groups (P < 0.001 for each). FEV1 was strongly correlated with Lung Sil R, Lung Sil L, Ant B-Mode R, and Ant M-Mode R (r = 0.963, P < 0.001; r = 0.956, P < 0.001; r = 0.953, P < 0.001; and r = 0.917, and P < 0.001, respectively). Negative correlations were detected between the number of exacerbations per year and Lung Sil R and the number of exacerbations per year and Ant M-Mode R (r = -0.599, P < 0.001 and r = -0.587, and P < 0.001, respectively). CONCLUSION: In this study, FEV1 and annual number of exacerbations turned out to be strongly correlated US findings. The use of US in COPD patients could help to support clinical decision, but further clinical studies are necessary to confirm those findings.

An underestimated comorbidity of COPD: Thyroid dysfunction.

Chronic obstructive pulmonary disease (COPD) has many systemic effects influencing morbidity and mortality of the disease. Thyroid diseases which are more common in COPD patients than who do not have COPD are underestimated despite important clinical consequences. Similar to general population, thyroid dysfunctions are more common in females than males among COPD patients. Both hypothyroidism and hyperthyroidism may be associated to COPD. As well as systemic inflammation hypoxia, age, glucocorticoid use and smoking are some of the effective factors on developing thyroid dysfunction in COPD patients. In this article thyroid dysfunctions that are underrecognized comorbidities of COPD patients, their mechanisms of action and clinical outcomes were reviewed.

Do N-terminal pro-brain natriuretic peptide levels determine the prognosis of community acquired pneumonia?

OBJECTIVE: Pneumonia is a leading cause of mortality worldwide, especially in the elderly. The use of clinical risk scores to determine prognosis is complex and therefore leads to errors in clinical practice. Pneumonia can cause increases in the levels of cardiac biomarkers such as N-terminal pro-brain natriuretic peptide (NT-proBNP). The prognostic role of the NT-proBNP level in community acquired pneumonia (CAP) remains unclear. The aim of this study was to evaluate the prognostic role of the NT-proBNP level in patients with CAP, as well as its correlation with clinical risk scores. METHODS: Consecutive inpatients with CAP were enrolled in the study. At hospital admission, venous blood samples were collected for the evaluation of NT-proBNP levels. The Pneumonia Severity Index (PSI) and the Confusion, Urea, Respiratory rate, Blood pressure, and age ≥ 65 years (CURB-65) score were calculated. The primary outcome of interest was all-cause mortality within the first 30 days after hospital admission, and a secondary outcome was ICU admission. RESULTS: The NT-proBNP level was one of the best predictors of 30-day mortality, with an area under the curve (AUC) of 0.735 (95% CI: 0.642-0.828; p < 0.001), as was the PSI, which had an AUC of 0.739 (95% CI: 0.634-0.843; p < 0.001), whereas the CURB-65 had an AUC of only 0.659 (95% CI: 0.556-0.763; p = 0.006). The NT-proBNP cut-off level found to be the best predictor of ICU admission and 30-day mortality was 1,434.5 pg/mL. CONCLUSIONS: The NT-proBNP level appears to be a good predictor of ICU admission and 30-day mortality among inpatients with CAP, with a predictive value for mortality comparable to that of the PSI and better than that of the CURB-65 score.

Diaphragmatic thickness in chronic obstructive lung disease and relationship with clinical severity parameters

Background/aim: Sonographic assessment of diaphragm structure and function would be a useful clinical tool in patients with chronic obstructive pulmonary disease (COPD). Our aim was to determine the muscle thickness of the diaphragm and the usefulness of clinical practice in patients with COPD. Materials and methods: The diaphragmatic thickness of 34 COPD patients and 34 healthy subjects was measured during tidal volume (Tmin) and deep inspiration (Tmax) on both sides using a B-mode ultrasound. The body mass index and the modified Medical Research Council (mMRC) index values were reported. Results: There was no correlation among TminR (P = 0.134), TminL (P = 0.647), TmaxR (P = 0.721), and TmaxL (P = 0.905) between the patients with COPD and the control group. There was also no significant difference between diaphragmatic thickness and COPD severity, respiratory function (P = 0.410), and frequency of exacerbations (P = 0.881) and mMRC (P = 0.667). Conclusion: Diaphragmatic dysfunction in COPD is related to mobility restriction rather than muscle thickness.

[Storage mite sensitivity and related factors in asthmatic patients]. / Astimli hastalarda depo akari duyarliligi ve iliskili faktörler.

INTRODUCTION: The aim of the study was to investigate the storage mite sensitivity and related factors in patients with asthma or asthma and rhinitis. PATIENTS AND METHODS: 149 patients with asthma or asthma and rhinitis were included to the study. Prick test was performed after addition of Acarus siro (A. siro), Lepidoglyphus destructor (L. destructor), Glycophagus domesticus (G. domesticus) and Tyrophagus putrescentiae (T. putrescentiae) to the standart prick test. Living conditions, smoking history, allergic diseases status, seasonal variations in symptoms were evaluated by a questionnaire. Besides, respiratory screening spesific IgE, L. destructor spesific IgE was examined in a group of patients who were allergic to storage mites according to prick tests. RESULT: Prick test results showed that; 115 of the patients were sensitized while 34 of them were not. House dust mite sensitivity was detected as mite 58.3%.The storage mite sensitivity for at least one of the studied species was detected in 61.7% of patients. The sensitivity rates were 50.4%, 48.7%, 47%, %40 for A. siro, L. destructor, G. domesticus and T. putrescentiae, respectively. The storage mite sensivity was found higher in the patients from the rural areas (p< 0.05). L. destructor IgE positiveness was detected in 9.1% of the group that antibody levels were examined. Positive reaction was detected for at least one of the storage mite species in %22.7 of the patients who were considered as not sensitized according to the results of the standart prick tests. CONCLUSIONS: As a result, storage mites are important allergens in subjects who live in rural areas and close contact with barn, haymow, bin and pantry. Addition of storage mite allergens to the standart prick test panel of patients living in rural area is suitable.

Incidence of pulmonary embolism during COPD exacerbation.

OBJECTIVE: Because pulmonary embolism (PE) and COPD exacerbation have similar presentations and symptoms, PE can be overlooked in COPD patients. Our objective was to determine the prevalence of PE during COPD exacerbation and to describe the clinical aspects in COPD patients diagnosed with PE. METHODS: This was a prospective study conducted at a university hospital in the city of Ankara, Turkey. We included all COPD patients who were hospitalized due to acute exacerbation of COPD between May of 2011 and May of 2013. All patients underwent clinical risk assessment, arterial blood gas analysis, chest CT angiography, and Doppler ultrasonography of the lower extremities. In addition, we measured D-dimer levels and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels. RESULTS: We included 172 patients with COPD. The prevalence of PE was 29.1%. The patients with pleuritic chest pain, lower limb asymmetry, and high NT-pro-BNP levels were more likely to develop PE, as were those who were obese or immobile. Obesity and lower limb asymmetry were independent predictors of PE during COPD exacerbation (OR = 4.97; 95% CI, 1.775-13.931 and OR = 2.329; 95% CI, 1.127-7.105, respectively). CONCLUSIONS: The prevalence of PE in patients with COPD exacerbation was higher than expected. The association between PE and COPD exacerbation should be considered, especially in patients who are immobile or obese.

OBJETIVO: Visto que a embolia pulmonar (EP) e a exacerbação da DPOC têm apresentação e sintomas comuns, o diagnóstico de EP pode ser negligenciado nesses pacientes. Nosso objetivo foi determinar a prevalência de EP durante a exacerbação da DPOC e descrever os aspectos clínicos em portadores de DPOC diagnosticados com EP. MÉTODOS: Estudo prospectivo conduzido em um hospital universitário na cidade de Ancara, Turquia. Entre maio de 2011 e maio de 2013, todos os pacientes hospitalizados por exacerbação aguda da DPOC foram incluídos no estudo. Todos os pacientes foram submetidos a avaliação de risco clínico, gasometria arterial, angiotomografia de tórax e ultrassonografia Doppler de membros inferiores. Além disso, foram medidos os níveis de dímero-D e de N-terminal pro-brain natriuretic peptide (NT-pro-BNP). RESULTADOS: Foram incluídos 172 pacientes com DPOC. A prevalência de EP foi de 29,1 %. Os pacientes com DPOC e dor torácica pleurítica, assimetria de membros inferiores e altos níveis de NT-pro-BNP, assim como aqueles que estavam obesos ou imobilizados, apresentavam maior probabilidade de desenvolver EP. Obesidade e assimetria de membros inferiores foram preditores independentes de EP nos pacientes com exacerbação da DPOC (OR = 4,97; IC95%, 1,775-13,931 e OR = 2,329; IC95% CI, 1,127-7,105, respectivamente). CONCLUSÕES: A prevalência de EP em pacientes com exacerbação da DPOC foi maior que a esperada. A associação entre EP e exacerbação da DPOC deve ser considerada nesses pacientes, especialmente naqueles imobilizados ou obesos. .

Should the cut-off value of D-dimer be elevated to exclude pulmonary embolism in acute exacerbation of COPD?

OBJECTIVE: The aim of this study was to evaluate the D-dimer levels in patients with chronic obstructive pulmonary disease (COPD) exacerbation with and without pulmonary embolism (PE) and to attempt to define a new cut-off value for D-dimer to exclude the diagnosis of PE in patients with COPD exacerbation. METHODS: This cross-sectional study was performed between the June 2012 and January 2013. The COPD patients who were admitted to the emergency department with acute exacerbation were consecutively included. D-dimer levels were measured upon admission. All patients underwent computed tomography angiography (CTA) and Doppler ultrasonography (US) of the lower extremities. RESULTS: A total of 148 patients were enrolled. Fifty-three patients (36%) who did not have PE had higher than normal (>0.5 pg/mL) D-dimer levels. The D-dimer levels of the COPD patients with PE were significantly higher than those of the patients without PE (2.38±2.80 vs. 1.06±1.51 pg/mL) (P<0.001). The cut-off value for D-dimer in diagnosing PE in the COPD patients was 0.95 pg/mL. The area under the receiver operating characteristic (ROC) curve was 0.752±0.040 (95% CI: 0.672-0.831) (P<0.001). CONCLUSIONS: This study showed that the D-dimer concentrations of COPD patients who are in the exacerbation period may be higher than normal, even without PE. The cut-off level for D-dimer was 0.95 pg/mL (sensitivity 70%, spesificity 71%) for the exclusion of PE in the patients with COPD exacerbation. The D-dimer cut-off value that is used to exclude PE in patients with acute exacerbation of COPD should be reevaluated to prevent the excessive use of further diagnostic procedures.

Does thromboprophylaxis prevent venous thromboembolism after major orthopedic surgery?

OBJECTIVE: Pulmonary embolism (PE) is an important complication of major orthopedic surgery. The aim of this study was to evaluate the incidence of venous thromboembolism (VTE) and factors influencing the development of VTE in patients undergoing major orthopedic surgery in a university hospital. METHODS: Patients who underwent major orthopedic surgery (hip arthroplasty, knee arthroplasty, or femur fracture repair) between February of 2006 and June of 2012 were retrospectively included in the study. The incidences of PE and deep vein thrombosis (DVT) were evaluated, as were the factors influencing their development, such as type of operation, age, and comorbidities. RESULTS: We reviewed the medical records of 1,306 patients. The proportions of knee arthroplasty, hip arthroplasty, and femur fracture repair were 63.4%, 29.9%, and 6.7%, respectively. The cumulative incidence of PE and DVT in patients undergoing major orthopedic surgery was 1.99% and 2.22%, respectively. Most of the patients presented with PE and DVT (61.5% and 72.4%, respectively) within the first 72 h after surgery. Patients undergoing femur fracture repair, those aged ≥ 65 years, and bedridden patients were at a higher risk for developing VTE. CONCLUSIONS: Our results show that VTE was a significant complication of major orthopedic surgery, despite the use of thromboprophylaxis. Clinicians should be aware of VTE, especially during the perioperative period and in bedridden, elderly patients (≥ 65 years of age).

Systemic inflammation and metabolic syndrome in stable COPD patients.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) has extrapulmonary effects that seems to be related with systemic inflammation. The relationship between metabolic syndrome which is an important determinant of systemic inflammation in general population and COPD is still not clear. The aim of the current study was to investigate the frequency of metabolic syndrome and C-reactive protein (CRP) levels, as a marker of systemic inflammation in stable COPD patients with different severity levels and in age and sex matched control group. PATIENTS AND METHODS: Ninety-one stable COPD patients and 42 control subjects were included in the study. The severity level in patients with COPD were determined according to GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria. ATP III (The National Cholesterol Education Program's Adult Treatment Panel III) was used in diagnosis of metabolic syndrome. Hs-CRP levels were measured in venous samples of patients and control subjects. RESULTS: The frequency of metabolic syndrome was found higher in patient group than control subjects, especially in GOLD stages I, II (p= 0.004). Abdominal obesity, hypertension, hyperglycemia components of metabolic syndrome were significantly more prevalent in patient group (p< 0.0001). Increased CRP levels were higher in control and patient groups in all GOLD stages, with metabolic syndrome than without metabolic syndrome (p= 0.047, p= 0.217, p< 0.001, p= 0.05, p= 0.467). CONCLUSION: The study showed that frequency of metabolic syndrome was higher in stable COPD patients than control subjects and general Turkish population. Abdominal obesity, hypertension and hyperglycemia were significantly more prevalent in patient group. Systemic inflammation was more intense in COPD patients with metabolic syndrome than without metabolic syndrome.

Erectile dysfunction: initial symptom of a patient with lung cancer.

INTRODUCTION: Penile metastases are rare and represent the advanced stage of the primary tumor. The patients usually have a history of a previously diagnosed malignancy and when metastasis to penis occurs, the most common findings would be priapism, pain, and difficulty in voiding. AIM: We aimed to present a patient who had erectile dysfunction as the initial symptom of lung cancer. Besides the unusual clinical presentation, the sonographic and magnetic resonance imaging (MRI) findings of the penile metastasis were also not typical. METHODS: A 57-year-old man with erectile dysfunction was admitted to the Department of Urology. On physical examination, there was a rigid, smooth, immobile, and painless mass at the base of the corpora cavernosa. Ultrasonography and MRI were performed in order to delineate the nature of the lesion. RESULTS: Radiological findings could not lead to a certain diagnosis and the lesion could not be resected completely during the surgery. Therefore, biopsy of the corpus cavernosum penis was performed. The histopathological diagnosis was metastatic malignant epithelial tumor consistent with nonsmall cell carcinoma. Further investigations revealed a metastatic lung cancer. CONCLUSIONS: Penile metastasis may rarely be the initial presentation of a malignancy and erectile dysfunction may be a seldom symptom.
