Active clinical trials for "Chronic Pain"

The proposed clinical trial will address the problem of opioid withdrawal. Opioids are essential for pain-relief in the short term, but their continued use is associated with a host of adverse effects. People living with chronic pain who were initiated on opioid therapy now find themselves with a major life-changing problem - dependence on opioid medications. Opioid withdrawal symptoms are a key barrier to decreasing or stopping their opioid medication. Currently, there are few medications that ameliorate the symptoms of opioid withdrawal. This problem is a major part of the opioid crisis in Canada, and impacts people across all demographics and socioeconomic status. A misconception is that only individuals with opioid use disorder are susceptible to opioid withdrawal; on the contrary, appropriate use of prescription opioids to manage pain can lead to significant symptoms of opioid withdrawal when it is reduced or stopped. Patients in Alberta who are at risk for opioid withdrawal, either from prescribed use or misuse will be primarily impacted by this trial. The investigators have recently explored the underlying causes of opioid withdrawal and identified an important target in the spinal cord that is responsible for producing withdrawal symptoms in rats and mice. The target, a protein called pannexin-1 (Panx1), is located throughout the body, specifically in the brain and spinal cord. Using sophisticated biochemical, genetic, and pharmacological techniques, the investigators demonstrated how Panx1 on immune cells is implicated in the production of opioid withdrawal symptoms after cessation of fentanyl and morphine in opioid dependent rodents. The investigators then attenuated these symptoms of withdrawal using probenecid, a drug which inherently blocks Panx1 activity. Because probenecid is a safe and clinically available drug, the findings could be immediately translated into clinical therapy to support people who are struggling with the symptoms of opioid withdrawal and provide clinicians with a safe and effective option for caring for this population.

The aim of this study will be to compare the effects of morphine versus ketamine when they are used as adjuvants to the local anesthetic in paravertebral nerve blocks performed with the aid of ultrasound. Furthermore, a group of local anesthetic without an adjuvant, will also be compared to the two groups

The study aims to assess the effect of spinal anaesthesia against a general anaesthesia with a femoral block, with respect to the incidence of chronic pain following a total knee replacement. It will also focus on genetic factors and their influence on chronic pain.

Persistent pain describes long term pain that is present nearly every day. It is common and affects millions of people in the United Kingdom. The investigators want to explore people's experience of living with persistent pain and investigate how pharmacists can help people manage their pain. For this, the investigators will be testing a digital Decision Aid Tool (DAT) that includes a pain and lifestyle assessment as part of a pain consultation.

Chronic wounds are important economic and health-care problem. Biofilm has been recognized as a major factor in wound chronicity, delayed healing, and persistent infections, increasing the need for frequent dressing changes, painful debridement and systemic antimicrobial treatments influencing quality of life. In the presence of "un-cultivating" bacteria and limitations of clinical indicators of biofilm presence, there is a need for simple "screening" diagnostic method for biofilm detection. Chronic wounds of different etiology often associated with chronic pain reduce working abilities and cause restrictions in everyday living diminishing patient's quality of life. Efficacy of hyperbaric oxygenation therapy (HBOT) in treating chronic wound and associated infection has been suggested. This observational prospective cohort study will be conducted at the Department of undersea and hyperbaric medicine and Department of dermatovenereology, Clinical Hospital Center Rijeka during 3-year period from 2021. to 2024. including all patients treated due to chronic wound irrespective of the ethology. The patients will be evaluated upon enrolment, after 2, 4, 6 weeks, and 3, 6, 9, 12 months period, to clinically evaluate the wound characteristics, evaluate clinical healing rate, clinical indicators of biofilm and/or infection, need for additional diagnostic or treatment procedures. The patients in both groups (control and HBOT group) will be treated with standard treatment (dressings, debridement, antibiotics, infection control), in addition HBOT sessions will be performed (HBOT group). Impact of chronic wound and both treatment options to patient related outcome measures will be evaluated assessing intensity and pain characteristics, quality of life, depression, and anxiety by means of standardized questionnaires (visual analogue scale, McGill Pain questionnaire, Wound Quality of Life Index, Health Quality of Life Questionnaire, Beck depression and anxiety inventory). Microbiological analyses of swabs/biopsies will be evaluated to determine microbial profile and resistance. Detection and objectivization of biofilm will be evaluated by standard methods on microbiological isolates (Congo red agar, tube method, tissue culture plate method) and confocal scanning laser microscopy, and on clinical samples by light microscopy. Primary and secondary objective will be assessed after 1 year follow-up.

Abdominal pain is a common symptom in patients with inflammatory bowel disease (IBD). Up to 70 % of IBD patients experience pain when the disease is active. Even when patients with IBD are in remission, 20-50 % experience ongoing pain. The precise mechanism of developing chronic abdominal pain in patients with IBD in remission remains unknown. The aim of this study is to identify psychophysiological and biological risk factors for the development of chronic abdominal pain in patients with newly diagnosed IBD (ulcerative colitis and Crohn's disease). This study consists of 4 sections (Study 1A, 1B, 2, and 3): Study 1A: We perform a longitudinal study in 150 patients with new-onset IBD over 18 months to identify risk factors related to the brain-gut axis for the development of chronic pain. This is a collaborative study with IBD BioResourse Inception study. We administer online questionnaires, collect stool and blood samples, and record heart rate. Other physiological data collected by the Inception study will be also used for the analysis. Study 1B: This is also a collaborative study with the Inception study. We will apply for our detailed questionnaires for 7 days (as per study 1A) to be administered to all the new patients (n=450) that are included in the Inception study on a voluntary basis. Patients will be followed for 12 months. Study 2 and 3: Study 2 and 3 are a questionnaire-based cross-sectional study in patients with IBD. The participants for study 2 are patients registered in IBD BOOST study and those for study 3 are patients registered in IBD BioResource (but not in IBD Boost study). Detailed online questionnaires will be administered to them. These studies are just one-day assessment.

The main aim of this study is to compare the effectiveness of three alternative techniques (continuous Erectus Spinae Plane Block : c-ESPB; continuous Serratus Anterior Plane Block : c-SAPB; and Intercostal Nerve Block: ICNB) in reducing the severity of early postoperative pain after Uniportal-VATS lung resections. Primary outcomes will be opioid and other analgesic drugs consumption in the 72 hours after surgery, and static and dynamic pain scores, measured by the visual analog scale (VAS), at 6 pre-established time-points during the first 48 hours postoperatively. Further outcomes will be incidence of pulmonary and cardiac complications until patient's discharging, pain when removing drains, presence/absence of chronic neuropathic pain (12 weeks after surgery).

This is a feasibility pilot trial assessing a behavioral intervention for chronic pain among disease-free cancer survivors to decrease long-term opioid dependence.

The purpose of this study (PASSION study) is to monitor symptoms of chronic pain before and after 2 weeks of a standard drug commonly used to treat elevated blood pressure compared with 2 weeks of placebo (crossover design) so that we may better understand how blood pressure affects your level of pain. This study is not testing an experimental drug.

Over the last years a rising medical need for treatment of chronic pain was identified. Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with chronic pain disorders due to traumatic or post-operative peripheral neuropathy. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic pain due to traumatic or post-operative peripheral neuropathy.
