Antibiotic treatment outcomes in community-acquired pneumonia

Background/aim: The optimal empiric antibiotic regimen for patients with community-acquired pneumonia (CAP) remains unclear. This study aimed to evaluate the clinical cure rate, mortality, and length of stay among patients hospitalized with community- acquired pneumonia in nonintensive care unit (ICU) wards and treated with a ß-lactam, ß-lactam and macrolide combination, or a fluoroquinolone. Materials and methods: This prospective cohort study was performed using standardized web-based database sheets from January 2009 to September 2013 in nine tertiary care hospitals in Turkey. Results: Six hundred and twenty-one consecutive patients were enrolled. A pathogen was identified in 78 (12.6%) patients. The most frequently isolated bacteria were S. pneumoniae (21.8%) and P. aeruginosa (19.2%). The clinical cure rate and length of stay were not different among patients treated with ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone. Forty-seven patients (9.2%) died during the hospitalization period. There was no difference in survival among the three treatment groups. Conclusion: In patients admitted to non-ICU hospital wards for CAP, there was no difference in clinical outcomes between ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone regimens.

The utility of neutrophil-to-lymphocyte ratio determined at initial diagnosis in predicting disease stage and discriminating between active and stable disease in patients with sarcoidosis: a cross-sectional study.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSION: 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.

The effect of inhaled corticosteroids in the outcomes of community-acquired pneumonia: ICCAP study (TURKCAP Database).

OBJECTIVE: We aimed to investigate the effect of inhaled corticosteroids (ICS) in the outcomes of community-acquired pneumonia (CAP), as well as to determine if ICS usage is exist among the risk factors for mortality in those patients. MATERIALS AND METHODS: In this retrospective cross-sectional multicentre study, 1069 hospitalised CAP patients were investigated using CAP Database of Turkish Thoracic Society (TURKCAP Database). The patients were divided into two groups, depending on their ICS use. The data were analysed by appropriate statistical methods. RESULTS: 172 (75.8%) of the 227 patients who were on ICS had COPD and 37 (16.3%) had asthma. There were fewer patients with fever among ICS-users compared to non-ICS users (P = 0.013), and less muscle pain (P = 0.015) and fewer GIS symptoms (P = 0.022). No statistically significant difference was found between ICS use/ type of ICS and the duration of hospitalisation (P = 0.286). The multivariate regression analysis showed that patients using ICS had lower body temperature and, less crackles/bronchial sound. In the multivariate logistic regression model lung cancer (OR: 6.75), glucose (OR: 1.01) and CURB-65 (OR: 1.72) were significantly associated with mortality in the CAP patients. ICS usage were not found to be associated with mortality. CONCLUSION: The use of ICS by the patients with CAP admitted to the hospital is not independently related with any radiological pattern, hospitalisation duration and mortality. ICS usage may diminish fever response and may suppress the findings of crackles and/or bronchial sounds. This needs further confirmation.

Analysis of young and elderly advanced stage nonsmall-cell lung carcinoma cases.

OBJECTIVE: Even though there have been considerable improvements in the diagnosis and treatment of lung cancer, the prognostic factors for elderly patients with advanced nonsmall-cell lung cancer (NSCLC) remain insufficient. Therefore, our aim is to compare the prognostic factors for elderly and young cases with advanced stage NSCLC. METHODS: The data of 370 advanced stage young (<65 years old) and elderly (>or=65 years old) NSCLC patients (Stage IIIB or IV) treated between 1995 and 2008 were retrospectively evaluated for the study at the oncology department. Demographic characteristics, treatment response, comorbidities, pleural effusion, performance status, and overall survival (OS) were correlated with patient clinical features and smoking habits at the time of diagnosis. RESULTS: Of the 370 patients, 284 (76.8%) were in the younger group and 86 (23.2%) were in the older group. The rates of stages (IIIB, IV) were similar in the elderly and younger groups. At the time of diagnosis, poor performance status, comorbidity, weight loss, anemia, and smoking status were more effective prognostic factors for elderly cases than younger ones. The treatment responses were also significantly different between the two age groups when the presenting symptom was weight loss: 18.7% of the younger group had progressive disease compared with 57.1% of the older group (P = 0.017). CONCLUSION: We concluded that treatment responses of the younger group were less affected by weight loss. These analyses suggest that weight loss at presentation can be useful in predicting disease response in patients with advanced stage elderly NSCLC.

Endobronchial Mucosal Neuroma with Sarcoidosis.

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.

Case of keratosis lichenoides chronica with atypical sarcoidal granulomatous inflammation.

Keratosis lichenoides chronica (KLC) is a rare chronic disease characterized by violaceous, papular and nodular lesions typically arranged in a linear and reticulate pattern. The etiology of KLC is unknown, but it may be associated with internal diseases such as hypothyroidism, glomerulonephritis and lymphoproliferative disorders. Herein, we describe the case of 44-year-old male patient with characteristic lesions of KLC on the trunk and extremities, present for 12 years. The clinical diagnosis was proven by histopathological examination on several occasions. In the years following the diagnosis of KLC, he developed bilateral hilar and multiple mediastinal, cervical and inguinal lymphadenopathies and hepatosplenomegaly. In 2000, diffuse interstitial and then reticulonodular pulmonary infiltrates associated with fever, weight loss, malaise and subcutaneous nodules developed. Biopsies taken from peripheral and mediastinal lymph nodes, pulmonary parenchyma, pleural tissue, bone marrow and skin showed non-necrotizing granulomas, indicating a sarcoidal granulomatous reaction. Characteristic histopathological findings and the absence of atypical cells, clonality and a high proliferative index excluded lymphomas. Furthermore, detailed tests showed no evidence of an infectious granulomatous disease. As far as we know, this is the first reported case of KLC associated with a sarcoidal granulomatous reaction.

Pneumococcal and influenza vaccination status of hospitalized adults with community acquired pneumonia and the effects of vaccination on clinical presentation.

BACKGROUND: Previous reports have shown that vaccination rates of adult at-risk populations are low in Turkey. There are differing reports with regards to the effectiveness of the influenza and the pneumococcal polysaccharide vaccine (PPSV23) on the clinical outcomes of community acquired pneumonia (CAP). The purpose of this study was to analyze the influenza (FV) and pneumococcal vaccination (PV) status, the factors that influence the receipt of influenza/pneumococcal vaccine and the effects of prior vaccination on the clinical outcomes in adults hospitalized with CAP. PATIENTS AND METHODS: Patients hospitalized with CAP between March 2009 and October 2013 and registered at the web-based Turkish Thoracic Society Pneumonia Database (TURCAP) were included in this multicentric, observational study. Of a total of 787 cases, data were analyzed for 466 patients for whom self-reported information on PV and FV was available. RESULTS: In this adult population with CAP, the vaccination rate with both the pneumococcal and influenza vaccines was found to be 6%. Prior FV was found to be the sole variable that was associated with the receipt of PV [OR 17.8, 95% CI (25-75:8.56-37.01), p < 0.001]. Conversely, being vaccinated with PPSV23 was the only predictor of receipt of FV [OR 18.1, 95% CI (25 - 75:8.75 - 37.83), p < 0.001]. Compared to the unvaccinated cases, the chest radiograms of the vaccinated patients revealed less consolidation. The latter also reported fatigue, muscle pain and gastrointestinal symptoms less frequently. Although there was a trend for lower 30-day mortality and for lower rates of intensive care unit (ICU) admission, these did not reach statistical significance. A pneumonia severity index (PSI) score ≥ 90, CURB-65 score ≥3 and multilobar involvement, but not the vaccination status, were identified as independent determinants of ICU admission. CONCLUSIONS: This study showed that, among patients hospitalized with CAP, the FV and/or PV rates are low. Prior vaccination does not appear to significantly affect the clinical outcomes.

Prognostic factors affecting survival in non-small cell lung carcinoma patients with malignant pleural effusions.

BACKGROUND AND AIMS: Lung cancer is the most common cause of malignant pleural effusions (MPEs). For patients with lung cancer and MPE, median survival is only 3-4 months. The aim of this study was to evaluate lung cancer patients with MPE by clinical and laboratory findings on admission, and determine 2-year survival rate and prognostic factors. METHODS: Between 2008 and 2011, we examined 199 cases of non-small cell lung carcinoma with MPE. Demographic factors of patients, tumor characteristics, treatment delivered and laboratory parameters affecting prognosis were evaluated. Survival rates were estimated by Kaplan-Meier method. Significance of each prognostic factors selected by univariate analysis were confirmed using Cox regression model. RESULTS: The study included 139 (69.8%) male and 60 (30.2%) female patients with a median age of 64 (30-85) years. Median overall survival was 4.4 months. Adenocarcinoma was the leading cause of MPE with 80.4%. A univariate analysis showed that factors affecting mortality included gender (P < 0.001), MPE with distant metastasis (P = 0.025), lower serum albumin (P < 0.0001), lower pleural protein (P < 0.0001), increased serum lactate dehydrogenase (P = 0.003), increased serum C-reactive protein (CRP) (P < 0.0001), increased white blood cells (P < 0.0001), histopathological type (P = 0.004) and treatment decision (P < 0.0001). A multivariate analysis revealed that patients who had high level of serum CRP (P = 0.017), lower serum albumin (P = 0.009) and lower pleural protein (P = 0.003), MPE with distant metastasis (P = 0.003) and those who were chemotherapy naive (P < 0.0001) had shorter survival. CONCLUSION: High level of serum CRP, lower serum albumin and lower pleural protein, MPE with distant metastasis were most important prognostic factors for non-small cell lung carcinoma in patients with MPEs.

Hospital Treatment Costs and Factors Affecting These Costs in Community-Acquired Pneumonia.

OBJECTIVES: Community-acquired pneumonia (CAP) accounts for an important part of hospital admissions and health expenses worldwide. The cost increases when treated in a hospital, and reports on this issue are limited in Turkey. This study aimed to investigate direct hospital costs and factors affecting these costs for patients who were hospitalized in our clinic because of the diagnosis of CAP. MATERIAL AND METHODS: The records of patients who had been hospitalized for the diagnosis of CAP were retrospectively reviewed. Demographic features, radiological features, pneumonia severity index (PSI), CURB-65 scorings, duration of hospitalization, treatments, and the results of treatments were examined. Total hospitalization costs and the expenses for intervention, medication, examinations, and additional services were recorded. The effect of data on the cost was evaluated. RESULTS: The study was conducted with 87 patients with CAP. The mean duration of hospitalization was 15.6 days and nine patients (10.3%) were exitus. The median total hospital cost was 2062 (451-11690) TL [952 euros (€), 1305 dollars ($)], and the median hospitalization expense per day was 148 Turkish Lira (TL) (68.3 €, 93.7 $). Medication expenses and total cost were higher in male patients than in female patients. Abscess/necrotizing pneumonia increased the cost depending on the infiltration that occurred either alone or with parapneumonic pleurisy. Whereas an increase in the PSI stage increased the total cost and expenses for intervention and medication, medication expenses increased in patients with CURB-65 score of 3 and 4 (p<0.05). Age, smoking, and low oxygen saturation level did not affect the cost. No statistically significant difference was found between the expenses of exitus patients and the expenses of patients who recovered. CONCLUSION: CAP can lead to high costs and result in death. In our study, it was concluded that the cost increased in male patients, patients with abscess/necrotizing pneumonia, and patients with high PSI scores.

Epidemiology and distribution of interstitial lung diseases in Turkey.

INTRODUCTION: There is very few data on the epidemiological features of interstitial lung diseases (ILD) in the literature. These studies on this subject suffer from limited number of patients. OBJECTIVE: The goal of this study was to evaluate the epidemiological features of ILD in Turkey. METHODS: Fifty-four investigators, 31 centres in 19 cities from six regions of Turkey, participated in the study. Two thousand two hundred forty-five newly diagnosed patients (51.8% females), led by Turkish Thoracic Society Clinical Problems Study Group, enrolled in this prospective study. RESULTS: The mean age was 51.8 ± 16.7 years. The mean age among males was 50.5 ± 18.6 years and 53.0 ± 14.6 years among females (P < 0.001). 23.8% of the cases had ILD with known causes, while 39.4% were in granulomatous group, 23.7% were idiopathic, and 4.4% were in the unclassified group. Overall, histopathologically confirmed diagnosis rate was 40.4%. Sarcoidosis was the most common disease (37%), whereas cases with idiopathic pulmonary fibrosis (IPF) constituted 19,9% of patients. 53% of the sarcoidosis patients were females, and the ratio reaches to 75% under 50 years of age (for this group, IPF ratio is %3). In contrast, sarcoidosis and IPF ratios were equal in males (25%). Sarcoidosis was 8% in men over 50, while IPF was %45. CONCLUSION: The overall incidence of ILD in Turkey was computed to be 25.8/100,000.
