Filter by:Radioligand therapy (RLT) using Lutetium-177 labelled PSMA is a promising new therapeutic approach to treat metastatic prostate cancer. This tumor-specific treatment is directed against prostate-specific membrane antigen (PSMA), which is overexpressed in prostate cancer cells. In the last few years, several lutetium-177 (177Lu, β emitter) labeled PSMA ligands have been developed and are currently applied to treat metastatic castrate resistant prostate cancer patients. To date, there are no prospective randomized studies published using this treatment in the hormone sensitive setting or in oligometastatic prostate cancer. Therefore, this study we will evaluate the effect of 177Lu-PSMA in patients with hormone sensitive oligo-metastatic prostate cancer.
This is a multicenter, prospective, observational study designed to determine the clinical sensitivity and specificity of the Abionic IVD CAPSULE Allergic Asthma panel performed on Abionic's abioSCOPE device using K3-EDTA anticoagulated plasma samples from atopic and non-atopic pediatric and adult patients. Patients' sensitization determined with the abioSCOPE will be compared to the clinical assessment of allergy.
Children are often reported to have antibiotics allergies, with approximately 10% of the US population labeled as allergic to an antibiotic. Recent studies have demonstrated that a large majority of children with a penicillin allergy label do not have a true IgE-mediated allergy. Appropriately delabeling antibiotic allergies has been shown to improve patient care outcomes and lower health care costs. However, efforts to implement these assessments in practice are lacking, particularly in the hospital setting. Therefore, there is a need for hospital-based risk assessment and delabeling strategies for hospitalized children. The investigator's objective is to determine the feasibility of implementing a hospital-based approach to penicillin allergy risk stratification and evaluation of patients at low-risk for true allergy.
Aluminium is used in many different cosmetic products, including make-up, deodorants and sunscreen. The purpose of this study is to investigate whether these everyday skin products with small amounts of aluminium can cause skin reactions in children diagnosed with contact allergy to aluminium. The study is conducted as a Repeated Open Application Test study (ROAT), a method originally developed to clarify the clinical relevance of questionable and positive patch samples, by imitating everyday use of a skin product.
About 20% of the general population are affected by an allergy - with an upward trend. Quite often, allergic people do not consider their disease as serious and suffer from subsequent complications, like allergic asthma, later in their life. The sooner the allergen source is identified, the sooner the therapeutic intervention (e.g. dietary recommendations, allergen avoidance, anti-inflammatory treatment or allergen immunotherapy) can be started. Cross-reactivity may also play an important role. Therefore, a comprehensive allergy test is essential for an optimal treatment of patients. Modern multiplex testing is an individualized diagnostic approach, which may help to identify eligible patients for allergen immunotherapy and may identify risk groups by analyzing the sIgE profile. Until now, published data on the clinical usability of multiplex allergy diagnostic test systems are often limited. Even though, available studies show a good correlation between conventionally used multiplex or singleplex assays (ISAC or ImmunoCAP) and the new multiplex assay (ALEX and ALEX²), the results are often based on small sample sizes investigating many different allergens. Therefore, this clinical performance study is conducted to evaluate the diagnostic accuracy of the ALEX² IgE multiplex test using the Multi Array Explorer (MAX 45k, MacroArray Diagnostics) automated laboratory system in comparison to a conventional IgE singleplex test system as well as clinical symptoms and skin prick test results in a total of 826 patients. Patients with the most common inhalant allergies (e.g. grass pollen, house dust mite or cat allergy) will be included as well as patients suffering from Hymenoptera venom allergy, which is the major cause of anaphylaxis.
Background: Nickel is a silvery metal widely used in nature and contained in many foods. Exposure to nickel is responsible for two different types of adverse reactions: Allergic Contact Dermatitis (DAC) and Systemic Nickel Allergy Syndrome (SNAS). The latter is characterized by the presence of extra-cutaneous manifestations, in addition to the skin lesions of the DAC, related to the introduction of nickel-containing foods. Therefore, a nutritional intervention is essential to reduce the symptoms of SNAS. Currently in the literature there are no nutritional guidelines on the treatment and management of patients suffering from SNAS and often the indications provided to patients involve the exclusion of groups of foods for prolonged periods, with the consequent risk of developing nutritional deficiencies and malnutrition. Objectives: to evaluate the efficacy of dietary indications, developed on the most recent scientific evidence, useful for the management of the symptoms associated with adverse reactions to Nickel. Provide practical indications to specialist staff in multidisciplinary patient management and make the patient aware of his problem and help him understand how to manage it independently. Target population: subjects over the age of 18, female, belonging to the U.O. Occupational Medicine Allergology Section at ICS Maugeri of Pavia, with previous diagnosis of Nickel allergy (patch test) and with the presence of gastrointestinal symptoms related to allergy.
Functional Dyspepsia-Postprandial Distress Syndrome (FD-PDS), is characterized by meal-related symptoms such as early satiation and postprandial fullness. Disturbances of gastric motor function have been implicated the pathogenesis of PDS symptoms, and hence, motility modifying agents are considered for the treatment of PDS. Prucalopride (Resolor®), a highly selective 5-TH4 receptor agonist which stimulates gastrointestinal motility throughout the GI tract, is currently approved for the treatment of chronic constipation. The objective of this study was to evaluate the effect of prucalopride on gastric sensorimotor function in healthy volunteers (HV). Methods A total of 17 HV (59% females, mean age 29.4±2.7 years) underwent a barostat and intragastric pressure (IGP) measurements after treatment with placebo or prucalopride (2 mg) in a single blinded cross-over fashion. Isobaric distentions with stepwise increments of 2 mm Hg starting from minimal distending pressure (MDP) and scoring of intensities of gastric sensations (0-6: pain) were used to determine gastric compliance and sensitivity. Gastric accommodation (GA) was quantified as the difference (delta) in intra-balloon volume 30 min before and 60 min after ingestion of 200 ml of a nutrient drink (ND) (1.5 kcal mL(-1)). GA measured by IGP was quantified as the drop of IGP from baseline during the intragastric infusion of ND until maximal satiation. During all tests, epigastric symptoms were scored every 5 minutes.
The present project will compare the effect of DH reduction using three different dentifrices (Sensodyne Repair and Protect - NOVAMIN technology; Dentalclean Daily Regenerator - REFIX technology; Dentalclean Daily Regenerator - REFIX technology + potassium citrate) in periodontal patients. The evaluation will be in 6 moments: T1 and T2- immediately before and after scaling and root planing (SRP) procedures; T3-after polishing sensitive areas with rubbers cups and the dentifrice determined for each group of patients and T4, 5, 6- After 2, 4 and 8 weeks of SRP. Profissional assessments and patient perception data will be performed.
Background : Although the hypersensitivity reactions to cephalosporins have been recently a more focused subject, studies on the cephalosporin as an allergen are significantly less frequent that those regarding penicillins. Most of the available data regards cephalosporin sensitization in patients previously allergic to penicillin. Like penicillins, cephalosporins represent one of the most prescribed classes of antibiotics. The diagnosis of cephalosporin hypersensitivity is based mainly on clinical history, skin tests (ST) and drug provocation tests (DPT). This succession of tests, performed in specialized services, allows to eliminate responsibility for the drug in many cases (80-85%). The drug allergy work-up also allows to identify profiles of allergy to cephalosporins, with different patterns of cross-reactivity. Objective: To analyse the characteristics of patients studied in our Unit for suspicion of cephalosporin hypersensitivity. Methods: This retrospective study will comprise all the patients who attended the allergy service of the UH of Montpellier from 1997 till 2018 with a clinical history evocative of cephalosporin drug hypersensitivity reaction (DHR), who underwent a drug allergy work up and who gave their consent to be included in the study . The Patients are selected from the Drug Allergy & Hypersensitivity Database (DAHD).
Fibromyalgia (FM) is a chronic musculoskeletal pain disorder with unknown causes. Our previous studies showed abnormal sensations of second pain (wind-up), indicating central hypersensitivity as an important mechanism of FM. Triggering events have been implicated as the cause of central hypersensitivity.
