RESUMO

INTRODUCTION: Severe exacerbations are the leading cause of fatal events in chronic obstructive pulmonary disease (COPD). The new Global Initiative for Chronic Obstructive Lung Disease strategy included the number of exacerbations in the grading of the disease. The primary aim of this study was to evaluate the potentially modifiable precipitating factors of frequent severe exacerbations requiring hospital admission in COPD. The secondary aim was to investigate the risk factors of readmission within 2 months following an exacerbation requiring hospitalisation. METHODS: Data regarding the number of exacerbations in the previous year, current comorbidities, medications, and clinical and functional status of COPD patients were evaluated. RESULTS: We included 107 COPD patients (85% men). The mean number of severe exacerbations was 1.3 ± 1.7 (per patient/per year), and 37.4% of the patients had frequent severe exacerbations (≥ 2/year). Multivariate analysis indicated that haematocrit < 41%, angiotensin converting enzyme inhibitor or angiotensin receptor blocker use, positive gastro-oesophageal reflux disease symptoms, poor adherence to inhaled therapy/regular outpatient follow-up visits and FEV1 < 50% were independent predictors of frequent severe exacerbations. Readmission rate within 2 months after hospital discharge was 39.3%. The independent risk factors of readmission were poor adherence to inhaled therapy/regular outpatient follow-up visits, serum haematocrit < 41%, and FEV1 < 50%. CONCLUSION: Chronic obstructive pulmonary disease patients with frequent exacerbations should be carefully assessed for modifiable confounding risk factors regardless of poor lung function to decrease exacerbation frequency and related poor prognosis.

RESUMO

OBJECTIVE: The first decision to be made in the case of community-acquired pneumonia (CAP) is whether hospitalization of the patient is mandatory. In this study, we aimed to investigate whether the addition of oxygenation parameters to CURB-65 has diagnostic value in predicting mortality in CAP. PATIENTS AND METHODS: A total of 903 CAP patients were included in the study. Patients with a CURB-65 score of 0 and 1 were classified as Group 1 and patients with a CURB-65 score of 2 or more were classified as Group 2. The prediction of mortality through Pneumonia Severity Index (PSI), CURB-65 and CURBS-65/CURBP-65 with the addition of SaO2 and PaO2 values; hence the four different models, was compared among all patient groups. RESULTS: As a result, 3.3% of the cases in Group 1 and 12.7% of the cases in Group 2 died. In both CURB-65 groups, it was noted that the frequency of patients with SaO2 <90% was significantly higher in the dead group than in the alive patient group (p=0.009 and p=0.001, respectively). In the univariate analysis, PaO2<60, and SaO2<90 were significantly associated with mortality. Model 2 (CURBS-65) and Model 3 (CURBP- 65) were examined, SaO2<90 (OR 2.08) was found to have an effect on death. In predicting mortality by the receiver operating characteristics (ROC) analysis, it was understood that the CURBS-65 score had a slightly higher area under the curve (AUC) value than CURB-65. CONCLUSIONS: As a result, it has been shown that the use of CURBS-65 scoring instead of CURB-65 clinical scoring may be more useful in predicting mortality.

RESUMO

OBJECTIVE: As the pandemic continues, different vaccine protocols have been implemented to maintain the protection of vaccines and to provide protection against new variants. The aim of this study was to assess hospitalized patients' vaccination status and document the efficacy of boosters. PATIENTS AND METHODS: The patients that were hospitalized due to COVID-19 were enrolled from 28 hospitals in Turkey for five months from September 2021. 5,331 confirmed COVID-19 patients from collaborating centers were randomly enrolled to understand/estimate the distribution of vaccination status in hospitalized patients and to compare the efficacy of vaccination/booster protocols. RESULTS: 2,779 men and 2,552 women of which 2,408 (45.2%) were admitted to Intensive Care Units participated in this study. It was found that the highest risk reduction for all age groups was found in groups that received 4 doses. Four doses of vaccination for every 3.7 people under 50 years of age, for every 5.7 people in the 50-64 age group, and for every 4.3 people over 65 years of age will prevent 1 patient from being admitted to intensive care. Regardless of the type of vaccine, it was found that the risk of ICU hospitalization decreased in those who were vaccinated compared to those who were not vaccinated. Regardless of the type of vaccine, the ICU risk was found to decrease 1.25-fold in those who received 1 or 2 doses of vaccine, 1.18-fold in those who received 3 doses, and 3.26-fold in those who received 4 doses. CONCLUSIONS: The results suggested that the addition of a fourth dose is more effective in preventing intensive unit care even in disadvantaged groups.

RESUMO

AIM: Pulmonary function tests (PFT) have an important role in the assessment of pulmonary and nonpulmonary complications of hematopoetic stem cell transplantation (HSCT). In this study the relationship between PFTs and DLCOadj values and the complications of HSCT was investigated. The possible role of iron overload in the deterioration of the PFTs after HSCT was also searched. METHODS: One hundred and fifty one patients who had undergone allogeneic HSCT between years 2003 through 2008, and had the records of PFTs prior to and at 1, 3, 6, 9 and 12 months after transplantation were included in the study. Prospectively collected data of these patients were analysed retrospectively. RESULTS: Although no significant difference was identified in other PFT parameters, a significant decrease in DLCOadj was determined after 1st and 3rd months of HSCT. A significant correlation was found between pretransplant DLCOadj value <%70 and sinusoidal obstruction syndrome (SOS) (P=0.001, r=0.323), but in multivariate analysis pretransplant DLCOadj was not an independent predictor of SOS; only total body irradiation (TBI) (OR: 3.673, %95 CI: 0.880-15.804), the day of platelet engraftment (OR=1.093, %95 CI: 1.029-1.161) and serum ferritin (OR=1.001, %95 CI: 1.000-1.001) were significant. Advancing age and serum ferritin levels >600 ng/mL were the independent risk factors for pretransplant DLCOadj <%70 (OR: 0.970, %95 CI: 0.941-0.999 and OR: 2.355, %95 CI: 1.058-5.241 respectively). CONCLUSION: Although a significant correlation exists between pretransplant DLCOadj values and post-transplant SOS development, pretransplant DLCOadj was not an independent predictor of SOS. Increased serum ferritin levels were common both for pretransplant DLCO decrease and post-transplant SOS development. Iron induced endothelial damage may be the common pathophysiologic mechanism causing lung and liver vulnerability, and DLCOadj may be a non-invasive method of demonstrating this vulnerability.

RESUMO

For the prevention and control of non-communicable diseases (NCD), an action plan on NCDs is intended to support coordinated, comprehensive and integrated implementation of strategies and evidence-based interventions across individual diseases and risk factors, especially at the national and regional levels by World Health Organization (WHO). The Global Alliance against Chronic Respiratory Diseases (GARD) is making every attempt to align with WHO's non-communicable diseases action plan. GARD activities have been commenced in over 40 countries and in 11 countries an integrated NCD action plan is being prepared or has already been initiated. This integrated approach of GARD has also targeted to GARD Turkey project. The Turkish Ministry of Health has decided to apply this national control program in conformity with other NCD action plans. This article is intended to summarize these integration efforts of GARD Turkey (the National Control Program on Chronic Airway Diseases) with other NCD national programs.

RESUMO

BACKGROUND: Sarcoidosis and chronic beryllium disease (CBD) are inflammatory conditions in which oxidative stress state may be crucial for disease outcome. This study compares haem oxygenase-1 (HO-1) extracellular activity for the first time in patients with sarcoidosis or CBD and in healthy controls. MATERIALS AND METHODS: Induced sputum was recovered using a standard protocol. Pulmonary function tests (PFT) were performed by conventional methods. T lymphocyte subsets (CD4 and CD8) were measured by flow activated cell shorter (FACS). The HO-1 and nitrite levels were measured by a bilirubin-biliverdin reductase-dependent reaction and Greiss reaction respectively. Ferritin and iron levels were measured by enzymatic reaction and chemiluminometric immunoassay respectively. RESULTS: The mean percentage of lymphocytes was significantly higher in the 36 sarcoid patients compared with that in the 17 controls (P=0.001). The mean CD4/CD8 ratio was significantly higher in the sarcoid and the 10 CBD patients compared to that in controls (P=0.000 and 0.002 respectively), as was the mean HO-1 activity (P=0.045 and 0.041 respectively). The HO-1 activity did not differ with the sarcoidosis stage. The HO-1 level and PFT parameters were negatively correlated. The differences in mean nitrite, ferritin and iron levels were non-significant between the three groups. The HO-1 and ferritin levels were correlated (P=0.008). CONCLUSIONS: We succeeded in non-invasively measuring the activity of HO-1 from cells of airways in spite of its being an intracellular enzyme. The HO-1 levels in sarcoidosis and CBD were abnormally elevated.

RESUMO

INTRODUCTION: The long-term prognosis of patients with community-acquired pneumonia (CAP) has attracted increasing interest in recent years. The objective of the present study is to investigate the short and long-term outcomes in hospitalized patients with CAP and to identify the predictive factors associated with mortality. PATIENTS AND METHODS: The study was designed as a retrospective, multicenter, observational study. Hospitalized patients with CAP, as recorded in the pneumonia database of the Turkish Thoracic Society between 2011 and 2013, were included. Short-term mortality was defined as 30-day mortality and long-term mortality was assessed from those who survived 30 days. Predictive factors for short- and long-term mortality were analyzed. RESULTS: The study included 785 patients, 68% of whom were male and the mean age was 67±16 (18-92). The median duration of follow-up was 61.2±11.8 (37-90) months. Thirty-day mortality was 9.2% and the median survival of patients surviving 30 days was 62.8±4.4 months. Multivariate analysis revealed that advanced age, the absence of fever, a higher Charlson comorbidity score, higher blood urea nitrogen (BUN)/albumin ratios and lower alanine aminotransferase (ALT) levels were all predictors of long-term mortality. CONCLUSION: Long-term mortality following hospitalization for CAP is high. Charlson score and lack of fever are potential indicators for decreased long-term survival. As novel parameters, baseline BUN/albumin ratios and ALT levels are significantly associated with late mortality. Further interventions and closer monitoring are necessary for such subgroups of patients.

RESUMO

Fungal pulmonary infections (FPIs) are frequent causes of mortality in hematopoietic stem cell transplantation (HSCT) recipients. Determination of the specific risk factors may improve the prognosis. The aim of this study was to evaluate the risk factors of FPIs due to HSCT. Patient history, physical examination, chest X-rays and the consultation records of the pulmonary disease department which were a part of the routine evaluation before and at first, third, sixth, ninth and twelfth months of HSCT were retrieved in 148 adult HSCT recipients. Results of the high-resolution computed tomography, fiber-optic bronchoscopy and the microbiological data were also included. FPI was diagnosed in 22 patients (14.9%). Multivariate analysis showed that increased ferritin levels (>1000 ng/ml; OR: 3.42, 95% CI 1.03-11.42, P=0.045) and the development of sinusoidal obstruction syndrome (SOS; OR: 5.09, 95% CI 1.53-16.90, P=0.008) were significant risk factors for FPIs. The sensitivity and specificity of ferritin >1000 ng/ml for the prediction of FPIs were 67 and 70%, respectively. There was a positive correlation between the increased risk of FPIs and pretransplantation ferritin levels (r=0.413, P<0.001) and increased ferritin levels and SOS (r=0.331, P<0.001). Increased pretransplantation ferritin levels and development of SOS are predictive factors of FPIs during HSCT.

RESUMO

Although it is well known that intravenous administration of MgSO4 as an adjunct to conventional therapy is effective in treating asthma attacks, the effect of nebulized MgSO4 as a vehicle for salbutamol has been less evaluated. The aim of this study was to compare the effects of nebulized salbutamol administrated through either MgSO4 or isotonic saline solution on the 'peak expiratory flow rate' (PEFR), other respiratory and clinical parameters, and hospitalization rate of patients suffering from moderate to severe asthma attacks. Twenty-six patients with asthma attack were enrolled in the study in a randomized single blind fashion. After obtaining initial peak expiratory flow measurements (PEFR) and clinical evaluation, all patients received 1mg/kg corticosteroids and oxygen therapy and then either isotonic MgSO4 (2.5 ml, 6.3%)+salbutamol (2.5 ml) or saline (2.5 ml)+salbutamol (2.5 ml) through a jet nebulizer (group 1 (n=14) vs group 2 (n=12), respectively). The nebulizations were repeated every 20 min for the first hour and every hour for the rest of 4 h. The PEFR measurements and clinical assessment were performed after nebulization at 20th, 60th, 120th, 180th and 240th minutes. Patients were discharged when PEFR reached the target level of 70% of predicted. The baseline PEFRs and clinical parameters were similar between groups 1 and 2 (50.2+/-18.5 vs 44.1+/-13.9, respectively, p>0.05). The mean% increase in PEFR at different measurement levels was similar between the groups. When the treatment response was evaluated within the groups, group 2 showed statistically significant increase in PEFR (% of predicted) 1h earlier than group 1 (60th vs 120th minute, p=0.003 vs p=0.007). The mean duration of achieving target-PEFRs was 105.7+/-72.1 min for group 1 and 118.3+/-96.7 min for group 2 (p>0.05). This study suggested that the additional usage of MgSO4 to nebulized salbutamol has no beneficial effect on the treatment of asthma attacks.
