Colesevelam Versus Placebo in Cholestatic Pruritus
Chronic Liver Disease38 patients with pruritus due to chronic cholestatic liver disease will be evaluated in an investigator initiated, multicenter, double-blind, placebo-controlled, 3-week study assessing the effects of colesevelam on pruritus. Colesevelam is an oral, non-absorbable bile-acid sequestrant much more potent than cholestyramine but free of adverse effects. It is registered as a lipid lowering agent. The intensity of symptoms will be scored by means of daily Visual Analogue Scales (VAS). Fatigue, quality of life and cutaneous scratch lesions will also be evaluated using quantitative instruments.
Uremic Pruritus, Cytokines and Polymethylmethacrylate Artificial Kidney
UremiaPruritusBackground: Uremic pruritus is one of the common complications in long-term dialysis patients. In general, many factors including xerosis, elevated serum calcium, phosphate, calcium-phosphate product, hyperparathyroidism and inadequate dialysis may contribute to it. Recently, researchers reported that immuno-hypothesis with high serum level of cytokines could be the cause of uremic pruritus. Polymethylmethacrylate (PMMA) artificial kidney (AK) has been reported to adsorb more serum cytokines than other high flux artificial kidneys. Methods: In July 2006, 30 patients with severe uremic pruritus from 300 chronic hemodialysis patients in a single center entered this prospective study. Their dialyzers were changed to PMMA AK for 4 weeks. The severity of pruritus was evaluated every week using the results of a questionnaire (pruritus score). Laboratory assays including pre-dialysis serum blood urea nitrogen, creatinine, β2-microgblubulin (β2M), calcium, phosphate, intact parathyroid hormone (iPTH), total CO2, ferritin, hematocrit, high sensitivity C-reactive protein (hsCRP), IL-1, IL-2, IL-6, IL-18, TNF-α, KT/V and β2M clearance were measured before and at the end of 4 weeks of PMMA AK use. Expected Results:To prove the PMMA membrane could improve the uremic pruritus and to reveal the effect of PMMA membrane on serum level of possible factors contributing to uremic pruritus.
Study of Effectiveness of Mexyn-A
PruritusAtomised Methoxymethane-in-Aqua (MEXYN-A) a new topical self-chilled, non-steroidal, non-flammable, pressurised spray which embodies in one simultaneous application, most of the currently recognised and effective chemical, mechanical and thermal anti-pruritic therapies and hydrotherapy.
The Effect of Phototherapy on Pruritus of Patients With Chronic Kidney Disease
Uremic PruritusThe purpose of this study was to confirm the efficacy of NB UVB phototherapy in alleviating uremic pruritus and investigate the association between improvement of pruritus and change of serum parameters, including routine biochemical data, immune profile and dialysis adequacy.
Optimal Dose of Prophylactic Naloxone in Reducing Opioid-Induced Side Effects in Children/Adolescents...
PainNausea1 moreThis is an investigator initiated dose finding study designed to determine the optimal dose of naloxone to prevent or minimize the most common side effects induced by opioids, namely itching, nausea, and vomiting. Male and female inpatients of the Children's Center of the Johns Hopkins Hospital, who are greater than 6 and less than 18 years of age with acute, moderate to severe pain, and who are to be treated with intravenous Patient controlled analgesia (IVPCA) morphine will be eligible for inclusion in this study. Patients will be recruited by a study investigator prior to the initiation of IVPCA therapy. The majority of patients will be post operative patients, and will start therapy and the investigational drug in the Post Anesthesia Care Unit or the Pediatric Intensive Care Unit. The investigators plan on studying between 10 and 99, male and female patients over a 2 year period.
Topical Acetaminophen for Itch Relief: a Proof of Concept Study in Healthy Subjects
PruritusCurrently, topical antihistamines and corticosteroids are mainly used for itching relief. However, the over the counter antihistamines are not effective on all itch conditions. Acetaminophen is a popular and widely used OTC drug for pain relief. Although its mode of action is still unknown, recent studies have shown that acetaminophen indirectly activates cannabinoid CB1 receptors. Recent studies have shown that topical cannabinoid agonists are effective for itch relief, the efficacy of topical acetaminophen will be tested for non-histaminergic itch relief.
