Active clinical trials for "Inflammation"

Around 7500 neonates born yearly in the United States have complex congenital heart disease that require surgical repair in the first few days of life. The complexity of the surgical repair requires long periods of cardiopulmonary bypass (CPB) and the use of intermittent periods of low flow or complete circulatory arrest. The immature neonatal vital organs are more prone to the complications of the cardiopulmonary bypass circulation, namely ischemia/reperfusion (I/R) injury and systemic inflammatory response. Inhaled nitric oxide (NO) is used frequently in neonates for the treatment of pulmonary hypertension, Additionally, many studies have shown that NO has an anti-inflammatory effect by reducing I/R injury and endothelial dysfunction. The purpose of this pilot study is to assess the efficacy of NO administration via the CPB circuit in attenuating the CPB induced I/R injury and systemic inflammatory reaction in neonates undergoing repair of complex congenital heart defects. Specific goals will be to demonstrate that NO use via CPB will: Decrease markers of I/R injury and systemic inflammatory response. Decrease platelet activation leading to reduced postoperative bleeding and transfusion requirements. Decrease postoperative organ dysfunction, and hence decrease operative mortality and postoperative morbidity. Twelve neonates undergoing repair of complex congenital heart defects will receive NO via the CPB circuit, for the duration of surgery. They will be compared to a control group of 12 similar patients. Serum levels of different ischemic reperfusion injury and inflammatory markers will be measured at different time points after surgery and will be correlated with different end organ function tests and clinical course in the postoperative period. The results will be compared between the two groups to try to determine the clinical benefit of NO administration through CPB circuit.

The human body knows a biphasic immunological reaction to sepsis. First, the pro-inflammatory reaction takes place, marked by the release of pro-inflammatory cytokines like TNF-α, as a reaction to the bacterial toxins. Secondly, the counter regulatory anti-inflammatory reaction arises. This phase is acting as negative feedback on the inflammation by inhibition of the pro-inflammatory cytokines. This is called "immunoparalysis", a pronounced immunosuppressive state, which renders patients vulnerable to opportunistic infections. Most of the septic patients survive the initial pro-inflammatory phase, but die during this second stage.Research in the past has shown that immunostimulatory therapy with GM-CSF or IFN-γ has promising effects on the pro-inflammatory reaction during immunoparalysis ex vivo. Both drugs are known for their immunostimulatory effects. Recent pilot studies have showed in septic patients, that long-lasting monocyte deactivation in sepsis ex vivo can be reversed by these two immunostimulants. However, the mechanism and extent of immunoparalysis recovery may be different between the two compounds. Previously it has been shown that human endotoxemia (induced by LPS), leads to marked immunosuppression in healthy individuals, characterized by a transient refractory state to a subsequent LPS challenge (endotoxin tolerance). Consequently, human endotoxemia can serve as a standardized, controlled model for sepsis-induced immunoparalysis. Until now, all studies have focused on the ex vivo tolerance. However, we have recently proved, that the ex vivo condition is not completely representative for the in vivo situation. Ex vivo, leukocyte tolerance to LPS resolves within one day, while the in vivo immunoparalysis persists for two weeks. In this project, we will investigate the effects of both GM-CSF and IFN-γ in a parallel double-blind placebo controlled randomized manner on the immunoparalysis following human endotoxemia, both in-vitro and in vivo. As a result, we hope to get more insight in the pathophysiology of sepsis-induced immunoparalysis and thereby develop new immunostimulatory therapies that improve patient outcome

The purpose of this study is to determine whether rinsing with an amine fluoride/stannous flouride mouthrinse in addition to daily tooth brushing is more effective than tooth brushing alone.

Opioids are the corner stone in the treatment of post operative pain. Because of the several side effects of opiods, non-steroidal anti-inflammatory drugs are usually added postoperatively to decrease the total requirements of opioids. However, non steroidal anti-inflammatory drugs have side effects of their own. Vitamin C, with virtually no side effects when used on short-term basis, has been shown to have promising analgesic effects in chronic pain and acute pain relief following orthopedic surgeries. The investigators propose to assess the role of a prophylactic single dose (2g) of vitamin C in reducing the intensity of pain and the consumption of opioids in patients undergoing laparoscopic cholecystectomy at AUB-MC. All eligible patients undergoing laparoscopic cholecystectomy at AUB-MC will be included in the study. Patients will be randomized into two groups to receive either single dose oral vitamin C (2g) (Study Group) or identically looking placebo capsules (Control Group). Both the patients and the investigation team will be blinded to the type of intervention. Intraoperative anesthesia management will be similar for both groups. Postoperative pain control will be achieved with patient controlled analgesia via a patient controlled morphine pump in both groups. At several time intervals and up to 24 hours postoperatively, the pain scores, morphine consumptions, nausea/vomiting scores, sedation scales, itching scales, and patient satisfaction scales will be obtained for all patients. Also, the peak vitamin C concentration will be determined for each patient. Patients demographics will be obtained and compared between both groups. The differences in pain scores, morphine consumptions, nausea/vomiting scores, and sedation, itching, and patient satisfaction scales will be compared between the two groups with the Student-t test, the analysis of variance, the Fisher exact test, and the Kruskal-Wallis test. The peak vitamin C plasma concentration will be correlated with the pain scores in each group using regression analysis. This study will provide relevant information on whether a single dose (2g) of vitamin C can reduce morphine requirements and non steroidal anti-inflammatory drugs need and thus eliminating their side effects in patients undergoing laparoscopic cholecystectomy.

This is a multicenter clinical trial, phase III, superiority, controlled by active medicine, double-blind, randomized, enroll 166 children, over 12 years old, with acute inflammation upper airway, characterized by nasal congestion and runny nose, lasting at least 24 hours and a maximum of 48 hours prior to inclusion. The subjects will be allocated in 2 parallel groups, and will receive the medicines of study, according of the randomization.

ACTG A5275 was a prospective, double-blind, randomized, placebo-controlled cross-over design pilot study evaluating the effect of atorvastatin on biomarkers of inflammation, coagulopathy, angiogenesis, and T-lymphocyte activation in HIV-1 infected individuals with suppressed HIV-1 RNA on stable protease inhibitor based antiretroviral therapy with fasting LDL cholesterol < 130 mg/dL. Atorvastatin is a drug approved by the Food and Drug Administration (FDA) for treating high cholesterol. Atorvastatin has also been able to lower the level of inflammation blood tests in certain other diseases but has not been studied for this purpose in people who have HIV. The main goal of this experimental study is to see how taking atorvastatin affects inflammation blood tests in people infected with HIV who do not need to take medicine for high cholesterol. In addition to observing the effects of atorvastatin on the level of inflammation measured in the blood, this study evaluated if atorvastatin is safe for people with HIV who are also taking medication for HIV.

The purpose of this study is to determine the effect of local application of minocycline microspheres on the periodontal inflammation and bone loss prevention in patients diagnosed with moderate-severe chronic periodontitis within a periodontal maintenance program.

To evaluate the safety and efficacy of OTX-DP as a sustained release drug (dexamethasone) depot when placed in the canaliculus of the eyelid for the treatment of ocular inflammation and pain in subjects who have undergone cataract extraction with intra-ocular lens implantation.

The investigators hypothesize that intensive acid suppression with a long acting high potency proton pump inhibitor (PPI) drug dexlansoprazole will lead to a greater decrease in levels of inflammatory mediators (compared to conventional PPIs) in the esophagus, which could potentially lead to decreased recurrence of intestinal metaplasia following endoscopic ablation.
