Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

This study aims to determine whether or not early spirometric detection and management of obstructive lung disease with combined fluticasone/azithromycin/montelukast therapy (FAM) can attenuate declining lung function, prevent the development of bronchiolitis obliterans, and improve patient outcomes following hematopoietic stem cell transplant.

Development of pulmonary hypertension (PH) in chronic lung diseases has both functional and prognostic implications . PH in Lung diseases is usually mild to moderate with preserved cardiac output, and evolves slowly alongside the progression of lung disease and hypoxemia . However, a minority of patients develop severe PH with elevations in pulmonary artery pressure that have been described as ''out of proportion'' to the underlying disease . The aim of this study is to compare the characteristics and outcomes of consecutive patients with PH-due to lung diseases diagnosed at our specialist referral center over a 1-year period.

This study is based on the hypothesis that the pharmacokinetics of antibiotics in children is different from adults. Cephalosporins and macrolide antibiotics are the common drugs for children with community acquired pneumonia, the investigators aim to study the population pharmacokinetics of cephalosporins and macrolide antibiotics in children receiving the drug for treatment of community acquired pneumonia, and to correlate it with treatment effectiveness and incidence of adverse effects. Potential Impact: This novel knowledge will allow better and more rational approaches to the treatment of community acquired pneumonia. It will also set the foundation for further studies that will be able to test improved therapies that may increase treatment response in vulnerable children.

The tumor associated CA-125antigen for diagnosis and follow-up of ovarian cancer was well defined. Increased serum CA125 level may have many diagnoses other than ovarian cancer, including breast, colorectal and lung cancer. 80% lung cancer patients were diagnosed at advanced stage. Malignant pleural effusion secondary to lung cancer represented the condition of cancer cell involved pleura. The CA-125 level may reflect the extent of tumor involved in pleura (tumor burden), it could be correlated with the prognosis. This study was performed to examine the properties of CA-125 by measuring pleural and blood CA-125 levels in lung cancer with or without malignant pleural effusion; meanwhile to examine whether the rate of decline in CA 125 during primary therapy as a surrogate indicator for survival.

To compare EGFR mutations between primary non-small cell lung cancer (NSCLC) tumours and corresponding CTCs isolated by a label-free microfluidic device-based system To characterize the association between clinical response in NSCLC patients treated with gefitinib and serial changes in CTC EGFR mutations detected by a label-free microfluidic device-based system The investigators recently developed a label-free, microfluidic device for capturing circulating tumour cells (CTCs) and acquired a Fluidigm Biomark digital PCR instrument for reliable low-level DNA quantification. The overall aim of this study is to test the feasibility of using these state-of-the-art devices to reliably detect clinically relevant EGFR mutations in CTCs.

Ventilator-associated pneumonia (VAP) is very common in the intensive care unit (ICU), affecting 9 to 40% of ICU patients and mortality rates range from 20 to 50% and may reach more than 70% when the infection is caused by multi-resistant and invasive pathogens. The most common pathogens that cause VAP are the Gram(-) bacteria. Findings indicate that TLRs serves as an important signal in the generation of protective innate responses to bacterial pathogens of the lung and that is required for effective innate immune responses against Gram-negative bacterial pathogens. There is genetic evidence that mutations in TLRs increase the risk of developing nosocomial infections. Understanding the TLR system should offer invaluable opportunity for manipulating host immune responses.

This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swedish population for diseases included in the National Immunization Program (NIP), and to affirm the population's protection against polio. To be able to recommend complementary immunizations to immigrated children, a sub study focusing on foreign born teenagers will also be done and compared to children of the same age born in Sweden.

A pilot, prospective, comparative study. To include both male and female patients who have presented an ischaemic stroke (full stroke or TIA) or an ACS, 5 to 30 days prior to inclusion. The proposed study aims to investigate and analyse the differences in functional and structural arterial properties between the patients who presented an ischaemic stroke and those who presented ACS. The hypothesis is that the patients in both groups will present differences partly in terms of their "traditional" cardiovascular risk factors, but also in terms of their arterial properties. All of the confounding factors studied (cardiovascular risk factors, treatments) will be taken into account in order to explain the differences in the arterial properties found between the two groups. Furthermore, the prevalence of signs and symptoms in the two populations will be studied.

Remodulin (Treprostenil sodium) is synthetic prostacyclin analog available as a solution for administration in the intravenous route. It is approved for treatment of class I - pulmonary hypertension functional capacity stage III-IV. A key factor for the success of pulmonary hypertension therapy is maintaining near constant blood level of a given medications along the day. A sudden decrease in the blood levels might lead to rebound phenomenon; abrupt increase in the pulmonary artery pressure which might lead to acute right ventricular failure and even to sudden death. As some PHT patients suffer are on hemo-dialysis therapy due to end-stage renal disease there is a need to document the variation of the blood level along the dialysis cycle.

Abstract Pneumonia is a leading cause of severe morbidity and mortality among adults. During the last two decades, several scores were developed to evaluate the probability of morbidity and mortality among patients with community acquired pneumonia (CAP), such as the PORT score and the CURB65. Recently, several studies showed that elevated Red Cell Distribution Width (RDW) could be used as a prognostic tool for predicting severe morbidity and mortality among patients with cardiac diseases. RDW is a quantitative measure for red blood cell (RBC) size variability. Recent studies have suggested that high levels of RDW are in association with higher mortality among cardiovascular patients. RDW has not yet been studied as a prognostic sign in CAP. The goal of this study is to examine the role of RDW as a prognostic factor for severe morbidity and mortality among patients who were hospitalized with CAP , independently to Hemoglobin levels, renal function and inflammatory markers.
