Filter by:Patients with pulmonary fibrosis and associated usual interstitial pneumonia that require mechanical ventilation for acute respiratory failure experience poor clinical outcomes. This may be influenced by the unfavorable interaction between the fibrotic lung and the stress and strain stimuli generated during controlled ventilation. Although there is no consensus on how to ventilate these patients, much of the recommendations followed in clinical practice are taken from the experience on patients with acute respiratory distress syndrome. Among these, measuring the esophageal pressures and adjusting positive-end expiatory pressure to make trans-pulmonary pressures positive can decrease atelectasis, derecruitment of lung, and cyclical opening and closing of airways and alveoli, thus optimizing lung mechanics and oxygenation. The effect of this strategy on the fibrotic lung has not yet been documented. With this observational study we aim at documenting the effect of PEEP titration maneuver based on end-expiratory trans-pulmonary pressure on lung mechanics of patients with pulmonary fibrosis and UIP pattern,
This Long-term follow-up is designed to evaluate the safety of patient with Alcoholic Liver Cirrhosis who had administered Cellgram-LC in PMC-P-07 study.
The aim of this work is to study the role of long non-coding RNAs WRAP53 and urothelial carcinoma-associated 1 (UCA1) as potential biomarkers in diagnosis of hepatocellular carcinoma.
The study looked at whether regular physical activity can influence sleep duration, sleep quality and/or anxiety in patients with chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). The link between exercise and sleep has already been observed in the literature, but the impact of exercise on sleep is poorly understood. The question is how important is the influence of regular physical activity on sleep, anxiety and depression in patients with COPD or IPF.
Acute respiratory distress syndrome (ARDS) is a severe form of acute lung injury and a major cause of Intensive Care Unit (ICU) admission worldwide. Despite a large number of randomized clinical trials, a specific and effective pharmacological approach for patients with ARDS is still lacking. Fibroproliferation is a crucial part of the host defence response, and severe fibrotic lung disease affects ARDS patients even years after acute phase resolution. Pirfenidone is an oral anti-fibrotic drug, approved and largely used for treatment of idiopathic pulmonary fibrosis (IPF). The effect of Pirfenidone in ARDS has been evaluated only in animal models. This is a randomized controlled study to evaluate for the first time the efficacy of Pirfenidone in ARDS.
Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points will be examined to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.
The study will compare two forms of advice regarding physical activity for patients hospitalized with cirrhosis that are preparing for leaving the hospital. One arm consists of current standard of care: simple oral advice on exercise. One arm instead gives patients a structured but simple paper template on physical activity.
In this randomized controlled trial , The patients who satisfy the below inclusion and exclusion criteria will be included and they will be randomised, according to 2 groups ( in total 110patients in each group) to receive either Midodrine+Tolvaptan or tolvaptan+placebo for 7 days followed by follow up for 1 month. These patients will be admitted to the hospital from OPD or emergency. In patients with cirrhosis with Patients with cirrhosis -there are two types of hyponatremia. hyponatremia is due to important losses of extracellular fluid, most commonly from the kidneys (because of overdiuresis due to treatment with excessive doses of diuretics) or from the gastrointestinal tract( hypovolemic hyponatremia) hyponatremia develops in the setting of expanded extracellular fluid volume and plasma volume with ascites and edema.This condition is known as hypervolemic or dilutional hyponatremia.A marked impairment of renal solute-free water excretion, resulting in disproportionate renal retention of water with respect to sodium retention.In SALT trail showed that tolvaptan showed improvement in Na+ concentration from baseline at 4 ,30 day. It acts on by increasing free water generation by blocking ADH receptors in distal convoluted tubule. A study by Patel et al in 2017 showed that midodrine also increasing the Na+ by increasing the free water delivery to distal convoluted tubules(in cirrhosis usually there is less water delivery to distal convoluted tubules in view of less GFR).Till now there is no study has been done as combination of midodrine and tolvaptan whether superior to tolvaptan alone or not .So our aim is to study combination of midodrine and tolvaptan verses tolvaptan alone in patients with hyponatremia.
In critically ill patients with liver disease like cirrhosis or ACLF, fluid therapy needs to be instituted after identification of patients who will be fluid responsive and initiate appropriate inotropes early to prevent the mortality associated with fluid overload. The parameters and methodology used for assessing fluid responsiveness have been studied earlier, but the optimum method is not established. Existing recommendations based on data regarding fluid responsiveness and choice of fluid for resuscitation from intensive care units in general cannot be applied to those with liver disease as the hemodynamic alterations that occur with liver disease, presence of hypoalbuminemia at baseline and presence of cardiac dysfunction interfere with the conventional methods of fluid status assessment, fluid responsiveness as well as the response to different types of resuscitation fluids. Therefore the investigators attempt to compare various methods to estimate current intravascular volume status of patient which could be helpful in guiding fluid therapy.
The cumulative risk of refractory ascites is in the order of 20% within five years of the development of ascites. An elevated sinusoidal pressure is essential for the development of ascites, as fluid accumulation does not develop at portal pressure gradient below 8 mm Hg, and rising corrected sinusoidal pressure correlates with decreased 24-hour urinary excretion of sodium.More recently, it has been hypothesised that bacterial translocation associated with portal hypertension in cirrhosis and related pathogen-associated, molecular pattern activated innate immune responses lead to systemic inflammation.This is associated with vasodilatation as well as release of proinflammatory cytokines, reactive oxygen and nitrogen species, contributing to organ dysfunction.This activates sympathetic nervous system stimulating reabsorption of sodium in proximal,distal tubules, loop of Henle and collecting duct as well as the renin-angiotensin-aldosterone system, leading to sodium absorption from distal tubule and collecting duct.[5]Renal sodium retention and eventual free water clearance due to non-osmoticrelease of arginine-vasopressin and its action on V2 receptor in the collectingduct underlie the fluid retention associated with oedema and ascites in cirrhosis.The lowering of portal pressure using non selective beta blocker has also been shown to reduce the development of ascites, refractory ascites and hepatorenal syndrome.Furthermore, the effect of non slective beta blocker on intestinal permeability, bacterial translocation and inflammatory response has been proposed to mitigate the risk of developing spontaneous bacterial peritonitis.
