Active clinical trials for "Chronic Pain"

Non Coronary Heart Surgery scheduled for the study , in patients with acute postoperative period Use of tramadol retard, metamizol and dekxketoprofen the effects on pain and character has been seen in the chronic phase targeted.

Why does acute post whiplash injury pain transform into chronic pain? Multi-modal assessment of risk factors and predictors of pain chronification

11-20% of patients undergoing abdominal surgery develop chronic abdominal pain. Adhesions are a common cause of chronic pain following surgery. Adhesions develop after up to 90% of laparotomies and 70% of laparoscopic surgeries. Obviously, not all adhesions cause pain. It is still poorly understood why adhesions cause pain in some patients, while other patients with adhesions experience no pain. In this study we explore possible mechanism through which adhesions might cause pain. For this purpose we will assess expression of molecular mediators (such as TRPV-1, SP, and the neurokinin receptor), histological characteristics, and fecal microbioma that might be associated with pain.Expression of these factor will be compared to sample from 30 patients with chronic pain attributed to adhesions, and 30 patients undergoing a reoperation with adhsiolysis for reasons unrelated to pain.

This is an open-label, randomised, single-dose, 3 arms study design.

Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Many factors can affect pain and its severity. This study aims to explore how the COVID-19 affects chronic pain patients in terms of pain in general, intensity of pain, desire for pain treatment including follow up visits and pain medication refills as well as sleep.

This study aims to develop and validate the first set of patient-reported outcome measures for recurrent urinary tract infection (UTI): the Recurrent UTI Symptom Scale and the Recurrent UTI Impact Questionnaire. These tools could be used in clinical practice, clinical trials and research to gather an insight into a patient's perspective of their recurrent UTI symptom severity and its impact on their life, as well as determining any possible improvement or other change in their condition due to interventions (e.g. antibiotic treatment).

To investigate if long-term treatment of paracetamol can be discontinued without no worsening on pain, health-related quality-of-life and level of function compared to continuing paracetamol treatment in patients aged 65 years or more.

The main aim of this study is to identify factors that may be associated with a better or worse response to interventional pain management therapies for the treatment of chronic lumbar pain in adult patients. If several predictive factors are to be identified, a predictive model will be developed.

Pain is the way our brain interprets certain bodily sensations. It is very difficult to describe or to put into words as perception and tolerance of pain varies widely between individuals. It is known that age, gender and past experience and memory of past experience all contribute to patients' feelings of discomfort and tolerance of pain, but the reason why some patients actually do not experience any pain at all post surgery is still unknown. Because pain affects every person at some point in their lives, it is of utmost importance that we can find more effective analgesic methods, and provide analgesia tailored to an individual's need as well as discovering new methods which may be able to identify those individuals who are more prone to suffering serious, or chronic pain. It has been proposed that epigenetic modifications may play a role in sensitivity to analgesia and response to trauma, such as post surgery. The effects of epigenetic changes on key genes and the role this plays in analgesia sensitivity and pain perception is deserving of further research. Epigenetics is a growing field of study in which there are genetic modifications that do not involve changes to base sequences in a gene, but that result nonetheless in changes to gene expression. It has long been known that changes in gene expression play an important role in the establishment of pain states. But it is not known whether a priming injury can induce lasting epigenetic marks which would result in an increase in both postoperative acute pain and the risk for chronic pain. Only by fully understanding these epigenetic mechanisms will we be able to offer better drugs for the treatment of pain, and to identify those at high risk of postoperative pain and postsurgical chronic pain. The purpose of this study is to determine whether severity of pain following surgical procedures, such as third molar surgery is related to baseline methylation status of the promoter region of IL-6 and TNF-α and changes in methylation status post surgery.

Background: The current study will prospectively follow-up on chronic pain patients treated with oil extracts of medical cannabis (MC) for a period of six months in "real life" conditions. This study will enable a deep investigation regarding the effects of the active extract of cannabis inflorescence formulated in oil, derived from the cannabis plant. The results may allow us to reduce the gap in understanding MC's effects on pain relief and its safety, to identify predictors for treatment success/ failure, as well as to enable us tailoring a personalize MC treatment by choosing optimal concentration and dose according to the patient needs. We hypothesize that following the treatment with oil extracts of MC for chronic pain, associations will be found between its effectiveness and the types of clinical pain, personality traits and demographic characteristics. We also do not expect serious (life threatening) adverse events to be reported. Methods: This study has been already approved by the ethics committee of Haifa University (approval number 216/19). The sample will include a prospective cohort of 600 patients with chronic non-cancer pain that will request license to use oil extracts MC. The patients who will be approved to receive a license will be followed-up longitudinally for a period of six months from the signing of the consent form. The patients will be asked to fill a variety of questionnaires that may indicate the outcome of the treatment. The follow-up will take place in four time points: at the time of approval of the license (before starting the treatment, baseline), as well as at one, three, and six months from the initiation of treatment. Data will be collected by a web based data collection technology (Qualtrics®). In cases which there are a need for it, the information will be gathered by phone or face to face meetings.
