Filter by:Several studies investigated the effectiveness of Gabapentin in Uremic Pruritus (UP). No previous studies investigated the use of fexofenadine in UP. The aim of this trial is to assess the safety and possible efficacy of fexofenadine in patients with UP.
Pruritus is defined as an unpleasant sensation leading to the need to scratch. Medications for pruritus are much less effective than those used for pain and it is imperative to find new therapeutic options. Over the last 20 years, the understanding of the pathophysiology of pruritus has progressed significantly, opening new possible therapeutic fields. Among these, cannabinoids seem very promising because the physiological inhibitory role of endocannabinoids, mainly produced by neurons, has been well demonstrated. Data from the literature suggest that the antipruritic effects of cannabinoids are due to a combination of effects on neuronal activation, transmission along the afferent pathway, and local modulation of keratinocytes and mast cells. The antipruritic effect is peripheral and central, through modulation of CB1, CB2 or TRPV1 channels. CB1 and CB2 receptors are specific cannabinoid receptors, CB1 being present at the central and peripheral level while CB2 is only peripheral and very present in the skin. Cannabinoids can also bind to TRPV1, and thus inhibit neurogenic inflammation by antagonizing or stabilizing this ion channel, which prevents neuronal activation by pruritogenic mediators. Phytocannabinoids are derived from cannabis and are used for a variety of purposes, with their development for medical purposes expanding rapidly. The two best known are tetrahydrocannabinol (THC) and cannabidiol (CBD). THC binds to TRPV1, CB2 and CB1, the activation of the latter being at the origin of parallel psychotropic effects. CBD binds mainly to TRPV1, which allows us to expect very favorable effects on pruritus, neurogenic inflammation and skin pain, without fearing side effects of this type. A limited number of studies suggest that cannabinoids may be useful topically or systemically, in humans or animals, but no comparative study with placebo has been performed. These encouraging results have been observed in cases of induced pruritus, idiopathic pruritus, eczema, uremic pruritus, cholestatic pruritus, prurigo, sensitive skin or even epidermolysis bullosa. Currently, the ANSM is conducting an evaluation of the effects of medical cannabis on severe pain. We propose to evaluate the effects on severe pruritus in a randomized placebo-controlled study one of the products chosen by the ANSM in this context, the oil LITTLE GREEN PHARMA, which we choose for its dominant CBD ratio (THC < 5 mg/ml, CBD > 5 mg/ml).
This study hopes identify the main pruritogens of ICP pruritus and provide new insights for the diagnosis, prediction, and treatment of ICP. Details are as follows: It is planned to include ICP confirmed pregnant women and healthy pregnant women who have given birth in the Peking University Third Hospital and Sichuan University West China Second University Hospital. Then progesterone sulfate levels in plasma samples will be quantified by High Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) and itch intensity will be quantified by questionnaires. Main study endpoint: To reveal new indicators of ICP diagnosis with high accuracy: single, multiple or combined indicators of progesterone sulfates and other molecules like bile acids; Secondary study endpoint: To determine whether progesterone sulfates can be used as an early screening indicator for ICP for disease prediction, specifically whether elevated levels of progesterone sulfates predate pruritus in pregnant women with ICP.
Opioids are often added with a local anesthetic to enhance the duration and quality of spinal anesthesia for cesarean delivery patients. However, spinal opioids are associated with a wide variety of side effects such as nausea, vomiting, (N/V) and pruritus (itching). The occurrence of pruritus can vary between 30% and 100% making pruritus the most common side-effect of intrathecal opioids and this rate is even higher in pregnant patients. Pruritus may require treatment which can be ineffective or sometimes reverse the analgesic effect of the opioids. Ondansetron is a safe and very commonly used Serotonin receptor antagonist treatment for local anesthetic opioid-induced pruritus used in pregnancy. The effect of different administration times of ondansetron in reducing pruritus or N/V in cesarean section (CS) cases has not been extensively studied and thus, this prospective study can help guide future clinical management of side effects caused by spinal intrathecal morphine administration.
This is a two- stage study. Stage I is a multicenter, open-label trial；Stage II was a multi-center, randomized, double-blind, placebo-controlled trial. About 250 maintenance peritoneal dialysis patients with moderate or above pruritus are planned to be enrolled.
The study will assess efficacy of intravenous lidocaine 1 mg/kg diluted with 0.9% sodium chloride to a volume of 100 ml to suppress intrathecal fentanyl induced pruritus. This will be compared to control group who will receive 100 ml normal saline as placebo. The main outcome is regression of initial VAS score with incidence of pruritus.
The goal of this study is to test the efficacy of Dupixent in improving post-burn itching symptoms versus the current standard of care.
the goal of this randomized clinical trial is to find the optimum sub hypnotic dose of iv propofol that prevents the incidence of itching induced from intrathecal morphine used in spinal anesthesia in caesarean section operation. the main questions it aim to answer are the number of patients complained of pruritus in the first 24 hours post operative period and the severity of the pruritus. participants will be divided into 4 groups. 1st group receives 0 mg of propofol , 2nd receives 10 mg , 3rd receives 20 mg and the 4th receives 30 mg.
Through a cross-sectional questionnaire survey, a general information questionnaire and Dialysis Frequency, Severity, and Symptom Burden Index were used to investigate the frequency, severity, and degree of symptom distress in MHD patients, and to analyze the differences in symptom distress status between long and short dialysis age MHD patients. Using the R 4.2.2 software qgraph package, construct symptom networks for MHD patients of long and short dialysis age through network analysis. Analyze network centrality indicators, including intensity, closeness centrality, and mediation centrality, to identify core symptoms and compare if there are any differences between the two groups, aiming to lay the foundation for precise and efficient phased symptom management.
Very little is currently known about the pathophysiology of pruritus sine materia according to the etiology. The creation of this cohort should make it possible to improve our clinical and biological knowledge according to the etiology, by collecting blood, skin, feces, and clinical data.
