Acute Effect of Sildenafil on Exercise Tolerance and Functional Capacity in COPD, IPF and Post Pneumonectomy...
Chronic Obstructive Pulmonary DiseaseIdiopathic Pulmonary FibrosisPulmonary diseases are increasingly important causes of morbidity and mortality in the modern world. Sildenafil, an orally administered a phosphodiesterase type 5 (PDE-5) inhibitor, targets the nitric oxide (NO) pathway. The drug was first approved for the treatment of Pulmonary Arterial Hypertension (PAH) in 2005. The aim of the suggested study is to examine the acute effect of oral intake of sildenafil on exercise tolerance and functional capacity in Chronic Obstructive Pulmonary Disease (COPD), Idiopathic pulmonary fibrosis (IPF) and post Pneumonectomy patients. The investigators hypothesize that oral ingestion of sildenafil prior the exercise may enhance exercise tolerance and improve function in COPD, IPF and post Pneumonectomy patients. Patients and Methods: Sixty chronic lung disease patients males and females (aged 30 to 90 years) 20 COPD (GOLD III-IV) [9, 39] , 20 IPF and 20 post Pneumonectomy patients will be recruit to this study. All subjects will carried out two maximal cardiopulmonary exercise tests (CPET) on bicycle ergometer in different days; 60 min after intake of placebo and 60 min after intake of 100 mg sildenafil (Pfizer, Sandwich, UK), in random order. In first meeting prior exercise test at rest standard pulmonary function test, diffusion of CO, TLC and RV will be measured. In addition, Doppler Echocardiography and blood samples for NT-proBNP will be taken prior and post each CPET. After 15-20 minute of passive recovery post exercise test all patients will perform 3 short functional tests including 6 minute walk test to assess functional capacity.
Effects of Whole Body Vibration Training in Patients With Interstitial Lung Disease
Interstitial Lung DiseaseScleroderma1 moreInterstitial lung disease (ILD) is a diverse group of parenchymal lung disorders characterized by restrictive lung function and impaired alveolar diffusion capacity, leading to dyspnea on exertion, reduced exercise endurance, and poor quality of life. Patients usually complain of progressive breathlessness, persisting non-productive cough, which occurs with exercise. Hemoptysis, fever, chest pain are also seen. The most common comorbidity in chronic lung diseases is the progressive loss of exercise tolerance. Not only dyspnea, but also peripheral muscle dysfunction and cognitive deficits such as, anxiety and depression are responsible for the reduction of mobility in the patient. In the context of pulmonary rehabilitation (PR) program to be applied in interstitial lung diseases; upper and lower limb endurance, stretching and relaxation techniques, aerobic exercise training, respiratory muscle training, training of energy conservation methods, support by determining oxygen requirement, nutritional evaluation, prevention of weight and muscle loss, psycho-social support. The purpose of PR programs in this disease is; to improve muscle strength, endurance, and mechanical activity, to improve dyspnea sensation, to improve functional capacity, to inform and educate the patient about the patient's disease. The use of whole body vibration (TVT) is an increasingly common method of therapeutic use in order to improve neuromuscular performance. TVT applications have shown that increases muscle activity, muscle strength and muscle strength, improves lower extremity blood circulation and balance, and increases growth hormone production. TVT training effects have rarely been studied in patients with pulmonary disease. Muscle strength and performance enhancement were significant effects of TVT, which was emphasized as a promising exercise method for those with chronic obstructive pulmonary disease (COPD). Over the past decade, endurance and strength training has been established as the most important components of exercise training programs in patients with COPD and ILD. Therefore, inclusion of TVT into exercise training programs in ILD patients may lead to beneficial results. The investigators hypotheses are: the combination of home respiratory exercises with whole body vibration training may lead to more improved respiratory muscle strength, dyspnoea, functional capacity, balance, peripheral muscle strength and quality of life in ILD patients when applied as an isolated intervention, home respiratory exercises programme may lead to lower results than combination programs.
Minocycline Therapy for Lung Scarring in Patients With Idiopathic Pulmonary Fibrosis - a Pilot Study...
Idiopathic Pulmonary FibrosisPulmonary fibrosis is essentially scarring in the lungs. Some types (DIP, NSIP) most often respond to therapy. Others like UIP (usual interstitial pneumonitis) rarely respond. UIP frequently progresses and has a poor prognosis with a survival of three to five years. In UIP, most often the cause cannot be determined and is therefore called Idiopathic Pulmonary Fibrosis (IPF). A prevalence rate of 27-29 cases/100,000 has been reported that may even be as high as 250 cases/100,000 in individuals 75 years of age. Idiopathic pulmonary fibrosis (IPF) is a chronic and fatal pulmonary disorder. Conventional treatment with immunosuppressive therapy has been disappointing, with a median survival of <40% at five years after diagnosis. Moreover, this therapy may lead to premature deaths that are a result of immunosuppression and susceptibility to infectious disease. Another problem related to IPF, is that we have an incomplete picture of the natural history of the pathogenesis of this disorder. Clearly, new strategies for therapy are necessary. Published evidence suggests that less than 20% of patients with IPF respond to corticosteroids (prednisone). In patients that fail steroids, immunosuppressant drugs such as azathioprine or cyclophosphamide are used. An international consensus statement recommends both steroids and azathioprine or cyclophosphamide from the onset of treatment. Unfortunately a large number of trials have shown little or no effect of these drugs on the progression of disease. There are currently no FDA approved drugs for the treatment of IPF. Laboratory findings establish that human specimens of Interstitial Lung Diseases including IPF demonstrate an impalance in expression of proteins (Th2 Cytokines, CC Chemokines, and CXC Chemokines). When these protein levels are in excess or low, they alter the normal lung mechanism, causing angiogenesis (abnormal blood vessel formation), inflammation, scar tissue formation and impaired immunity of the patient. We hope to establish that the efficacy of anti-angiogenetic agent as an add on therapy for IPF patients, will prove to bring stabilization or improvement. Minocycline has been shown to inhibit angiogenesis (new abnormal blood vessel formation) and thus affect the fibrotic process (prevent scar tissue formation). Laboratory and animal studies support a potential therapeutic role for Minocycline in IPF. Minocycline is a semi synthetic derivative of tetracycline. It was first marketed as an antibiotic in 1972. Clinical trials of minocycline have mainly been performed in sexually transmissible diseases and in acne. Minocycline is also used to treat several other diseases such as nocardiasis, mycobacteriosis, leprosy, lyme disease, pyoderma gangrenosum, autoimmune bullous dermatitis, carteaud disease, and prurigo. The usual side effects of minocycline are: lightheadedness, dizziness, or vertigo and pigmentation. We will investigate genetic, molecular, cellular, whole animal models, and human specimens from patients with fibrotic lung disease to test our prediction: The pathogenesis of pulmonary fibrosis (lung scarring) is due to "multiple hits" that causes an inbalance of certain mediators (proteins) that are responsible for abnormal blood vessel formation, scar tissue formation (with and without inflammation inside the lungs) and impaired immunity of the patient. Each of the 3 projects in this proposal have a direct link to other projects and clinical core. The SCOR clinical core will identify and enroll patients with Interstitial Lung diseases (ILD), including IPF. The clinical core will collect clinical data, as well as obtain fluids from lung washings and human lung tissue specimens. Each project will use human specimens as indicated in each of their specific aims to correlate their findings with response to therapy.
Efficacy of Steroid Pulse Therapy in Acute Exacerbation of Idiopathic Pulmonary Fibrosis (AE-IPF)...
Idiopathic Pulmonary Fibrosis With Acute ExacerbationIdiopathic pulmonary fibrosis is the most severe form of interstitial lung disease. It is known that the prognosis is poor due to extensive inflammation and fibrosis of the lung parenchyma. In case of acute exacerbation, the prognosis becomes worse. In early studies, the 3-month mortality rate reached 50-80%, and in a recent study, the 1-month survival rate was 66%, and the 3-month survival rate was 41%. It is known that 20% of patients with IPF will experience acute exacerbations in their lifetime. The most commonly used treatment for such acute exacerbations is antibiotics and high-dose steroids, or steroid pulse therapy. However, its effectiveness is unclear, and the survival rate is still low. However, as there is no evident therapeutic agent other than steroids, it is included in the treatment guidelines, so conservative treatment is administered while steroids are administered to patients with acute exacerbation of idiopathic pulmonary fibrosis in most upper institutions. There is no precise treatment other than steroids for patients with idiopathic pulmonary fibrosis-acute exacerbation, but the side effects of steroid administration cannot be overlooked. Therefore, a study is needed to confirm whether steroid pulse therapy is necessary or not. Inclusion criteria Among patients with clinically or histologically confirmed idiopathic pulmonary fibrosis, patients who visited the emergency room with dyspnea symptoms Patients within 1 month of exacerbation of respiratory symptoms Patients with increased GGO or worsening of IPF on chest CT within the last 2 weeks Patients who understand the purpose of the clinical study and voluntarily agree to participate in this clinical study When it is determined that steroid administration is necessary under the judgment of the medical staff during the treatment process Exclusion criteria Patients who complain of dyspnea symptoms due to causes other than the respiratory system, such as fluid overload, congestive heart failure, pulmonary embolism, etc. Patients whose respiratory symptoms have worsened for more than 1 month Persons who cannot read consent forms (eg. illiterate, foreigners, etc.) Study design Using an open-label RCT randomization method, the administration will be divided into Group 1 (high-dose followed by low-dose steroid administration) and Group 2 (high-dose/low-dose steroid administration after steroid pulse therapy). Test group: Group 1 (high dose followed by low dose steroid administration) Control group: Group 2 (high-dose/low-dose steroid administration after steroid pulse therapy) ▶ Steroid administration Protocol Group 1: Methylprednisolone 1 mg/kg 7 days → 0.5 mg/kg 7 days → 0.25 mg kg 7 days Group 2: Methylprednisolone 10 mg/Kg (500 mg ~ 1g) pulse 3 days -> Methylprednisolone 1 mg/kg 7 days → 0.5 mg/kg 7 days → 0.25 mg/kg 7 days Response evaluation The level of inflammatory markers Imaging improvement: chest x-ray or CT Pulmonary function test: performed at the outpatient clinic before discharge or 12 weeks after the first visit for acute exacerbation

Acute Effects of Oxygen Supplementation Among IPF Patients
Idiopathic Pulmonary FibrosisIdiopathic pulmonary fibrosis (IPF) is a disease characterised with significant morbidity and poor prognosis. Dyspnoea and impaired exercise capacity are very common manifestations of the disease, and result in significant impairment of patients' quality of life. Although hypoxemia is common among subjects with IPF, published data on the effects of supplementary oxygen therapy on specific clinical outcomes among these patients are currently few, while the existing data on the potential benefits of oxygen supplementation to treat exercise-induced hypoxemia, in this patient population, are even more controversial. Based on the aforementioned, the purpose of this prospective, cross-over clinical trial is to investigate the acute effects of supplemental oxygen administration on the: a) exercise capacity, b) severity of dyspnea, c) cerebral oxygenation, b) muscle oxygenation, and e) hemodynamic profile, as compared to delivery of medical air (sham oxygen), in a group of patients with IPF, without resting hypoxemia, during steady state cardiopulmonary exercise testing (CPET).
Evaluate Safety and Efficacy of Intravenous Autologous ADMSc for Treatment of Idiopathic Pulmonary...
Idiopathic Pulmonary FibrosisDespite intense research efforts and clinical trials, there is still no effective treatment that can prolong the survival of patients with IPF. Conventional therapeutic approach includes combination of corticosteroids, anti-oxidants, immunodepressants and immune modulatory anti-fibrotic agents to be discontinued 20 days before screening. The only, so far, therapeutic approach that has been proven effective in terms of prolonging patient's survival is lung transplantation. Nonetheless, not all the patients with IPF are eligible for lung transplantation; there is a significant proportion of these patients that finally succumb while waiting in a lung transplantation list. Therefore, there is critical need for more effective and reliable therapeutic modalities5. Adult Stem Cells (ASCs) seem to represent one of these. Therefore, it is conceivable to assume that adult-stem cells can be easily and safely be applied as a novel therapeutic agent in chronic and fatal lung diseases, including chronic obstructive pulmonary disease (COPD) and IPF. Therefore, there is an urgent need to provide a safe, effective and affordable treatment option for IPF patients. New diagnostic, prognostic and therapeutic strategies need to be developed to reduce the burden of IPF. Given the present lack of appropriate treatment adjunctive in the therapy of IPF, adipose derived stromal vascular fraction provides new opportunities for development of the same. MSCs are having anti-fibrotic activity and hence may be excellent source to tackle pulmonary fibrosis and hence could be explored for their therapeutic potential for treating Idiopathic pulmonary fibrosis. MSC's also display membrane-bound and insoluble secreted molecules involved with cell attachment to neighbouring cells and to the extra cellular matrix.18 This cell surface configuration may enable mesenchymal stem cells to home from bloodstream to mesenchymal tissue.14 As limited clinical information is available about use of SVF and MSC in the IPF patients hence this Open Label, Prospective, Randomized multi center comparative study has been undertaken to explore the tolerability & effectiveness of SVF in one treatment arm and MSC in second treatment arm in IPF patients. Adipose derived stromal vascular fraction and Mesenchymal Stem Cells has been found in preclinical studies to be safe and effective
Therapeutic Plasma Exchange, Rituximab and IV Ig for Severe Acute Exacerbation of IPF Admitted in...
Exacerbation of Idiopathic Pulmonary FibrosisIdiopathic pulmonary fibrosis (IPF) is a fibroproliferative, irreversible disease of unknown cause, occurring mainly in patients older than 50. IPF is a rare but fatal lung disease, with an estimated prevalence of 14 to 28/100000 and a median survival time of 3 years. Acute exacerbation of IPF (AE-IPF) is a major event of IPF, as it is responsible for the death of 30-50 % of IPF patients; its annual incidence varies between 5 and 10%. The current literature indicates that IPF is associated with the development of an auto-immunity process targeting epithelial and endothelial lung cells. Autoantibodies have been associated with a poorer prognosis. A study by DONAHOE et al. (Plos One, 2015) indicates that the combination of corticosteroids, plasma exchanges, rituximab and immunoglobulins may improve the prognosis of the most severe forms of AE-IPF. In that study, the observed survival rate in patients receiving this combination of treatment was 70% as compared with 20% in historical controls. This therapeutic combination approach is designed both to eliminate and inhibit the production of circulating antibodies targeting the lungs. Considering the high mortality rate of an AE-IPF episode and the potential benefit of such an original approach, a well-conducted randomized controlled trial is critical.
Self-monitoring of Spirometry & Symptoms Via patientMpower App in Idiopathic Pulmonary Fibrosis...
Idiopathic Pulmonary FibrosisSingle-arm, open-label observational study in idiopathic pulmonary fibrosis (IPF) patients receiving usual care at an interstitial lung disease specialist center. The objectives are [1] to characterise the longitudinal trends of patient-measured Forced Vital Capacity (FVC) and impact of IPF on daily life Patient Reported Outcome Measures (PROM) in a cohort of patients with IPF [2] to determine the correlation (if any) between patient-measured FVC and PROMs with clinic-observed measurements and [3] to assess if longitudinal trends in patient-measured FVC are predictive of clinical health outcomes in IPF. An additional purpose is to assess the acceptability and utility of the patientMpower app in helping IPF patients and their healthcare professional caregivers manage their condition. Patients will record FVC, symptoms (e.g. dyspnea) and activity (step count) daily and PROM once a week on the patientMpower app. The planned observation period is sixteen weeks. No additional clinic visits are required (versus usual care). In-clinic assessments of lung function, dyspnea and PROM will be done at baseline and study end. Patients and healthcare professionals will provide their opinion on utility and acceptability of patientMpower app at study end.
