Pulmonary TBPulmonary Tuberculosis1 more

The goal of this clinical trial is to evaluate 3 dose levels of TBAJ876 for 8 weeks in combination with pretomanid and linezolid, compared to 8 weeks of Isoniazid, rifampicin, pyrazinamide and ethambutol (2HRZE), in adult participants with newly diagnosed, smear-positive, pulmonary drug sensitive tuberculosis (DS-TB). The main questions the trial aims to answer are: What is the optimal dose of TBAJ876 to continue further in development. What is the bactericidal activity of bedaquiline with pretomanid and linezolid (B-Pa-L) compared to 2HRZE and TBAJ876-Pa-L over 8 weeks What is the efficacy and safety of the 26-week B-Pa-L regimen compared with the SOC (2HRZE/4HR) in participants with DS-TB. Participants will be seen regularly during treatment (up to 26 weeks) and follow-up (52 weeks post treatment) for safety and efficacy assessments, including but not limited to: Safety labs, ECGs, vital signs, physical exams, PK sampling, neuropathy assessments and adverse event monitoring Sputum collection

Geisinger Antibiotic Allergy Pilot Program: Assess and Address

Penicillin Allergy

This is a prospective non-inferiority study to evaluate penicillin allergy history in patients with reported penicillin allergy, who require penicillin or penicillin-derivative antibiotic during inpatient admission using a focused questionnaire. A simplified scoring system will be assigned to patient responses, and the total score will be utilized to identify low-risk patients that have a minimal risk of allergic reactions on exposure to penicillin or its derivative. Patients determined to have low risk based on this questionnaire will be offered a test dose (graded challenge) of amoxicillin in a supervised setting, and if they tolerate it, penicillin allergy label will be removed from patient's chart. We hypothesize that at least 95% of low-risk patients will successfully pass the graded amoxicillin challenge so the penicillin allergy label can be removed from their charts. A proportion as low as 0.85 would be a good clinical outcome and considered non-inferior to the expected proportion of 0.95.

KIR Genes and Non-Celiac Wheat Sensitivity

Non-celiac Wheat Sensitivity

Non-celiac gluten sensitivity (NCGS) is a condition characterized by gastrointestinal and extraintestinal symptoms which are triggered by gluten ingestion in the absence of celiac disease (CD) and wheat allergy. In the last years studies suggested that wheat components other than gluten can be responsible of symptom's triggering, thus the term "non-celiac wheat sensitivity" (NCWS) has been proposed as a more appropriate label. To date, different pathogenetic mechanisms have been proposed, but no conclusive data have been reported; among these, some study groups a possible role of innate immunity and of Natural Killer (NK) cells. KIR (Killer Immunoglobulin-like Receptors) regulate the activation of NK cells through their interaction with Human Leucocyte Antigens (HLA). Both KIR and HLA loci are highly polymorphic, and, in the case of KIR, two main haplotypes have been identified: A and B. Haplotype A is the simplest and correlates mainly with NK inhibition, while haplotype B has a variable number of genes, most of which activate NK cells. The investigators hypothesis is that the genetic variants of KIR, which define the haplotype "inhibitor" or "activator", can affect the development and the course of NCWS too. Thus, the researchers aimed to:1. Identify putative KIR genetic variants in NCWS patients (50 subjects) respect to celiac disease patients (50 subjects) and blood donors (50 subjects); 2. Evaluate the possible association of KIR genetic variants with specific clinical manifestations of patients with NCWS.

Penicillin Allergy Risk-Stratification and Delabeling of Low-Risk Patients

Antibiotic Allergy

Children are often reported to have antibiotics allergies, with approximately 10% of the US population labeled as allergic to an antibiotic, however, recent studies have demonstrated that the majority of symptoms reported as an allergy by parents are often non-IgE-mediated adverse reactions or symptoms of a viral illness (e.g. rash, vomiting, diarrhea). Additionally, over 90% of patients with reported penicillin allergy have negative skin testing results. Several studies in children have found that an allergy questionnaire can accurately identify those who are at low risk for severe antibiotic allergy and the allergy label can be safely removed. Appropriately delabeling antibiotic allergies has been shown to improve patient care through changing prescribing behavior and lowering health care costs. In this study, the investigators will perform a randomized trial comparing a provider-targeted clinical decision support tool to a pharmacist-led approach. The physician-targeted CDS tool will inform providers of their patient's allergy risk stratification result, protocol, electronic health record order and documentation support. The pharmacist-led approach consists of electronic health record dashboard that includes identical information to the provider arm. The primary outcome will be the frequency of penicillin allergy encounters with an allergy label removed at the time of discharge. Secondary outcomes will include the percentage of encounter with a penicillin allergy label in the electronic medical record 3 months after discharge, hospital length of stay and antibiotic utilization.

Hypersensitivity to Opening of BKCa Channels in Post-Traumatic Headache

Post-Traumatic Headache

The aim is to investigate whether opening of large conductance calcium-activated potassium (BKCa) channels induces headache with migraine-like features in people with persistent post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI).

The Efficacy of Nigella Sativa in Children With House Dust Mite-Induced Respiratory Allergy Receiving...

House Dust Mite Allergy

An experimental study aims to investigate the efficacy of Nigella Sativa in children with house dust mite (HDM)-induced respiratory allergy receiving immunotherapy. This study observes symptom, medication, combine symptom-medication score, quality of life (QoL), skin prick test, IL-4, TGF-β, IL-10, IgG4 specific HDM, IgE Specific HDM, and IFN-γ as the outcome. This study will be done on 40 subjects (20 subjects in control group and 20 subjects in experimental group), in children diagnosed with house dust mite-induced respiratory allergy such as allergic rhinoconjunctivitis and/or asthma, with an age of 2 to 17 years old, receiving allergen specific immunotherapy, not having an autoimmune disease, malignancy, nor chronic respiratory infection at the beginning of study, and has an approval from their parents. In control group, subjects will receive allergen specific immunotherapy and standard pharmacotherapy for underlying diagnose. In experimental group, subjects will receive nigella sativa oil for 14 weeks, allergen specific immunotherapy, and standard pharmacotherapy for underlying diagnose. All subjects will observe for 14 weeks during build up phase of immunotherapy. They will be monitored regularly, since this study starts, at each week, and at the end of this study. The symptom, medication, and combine symptom-medication score will be calculated at every session of monitoring. Quality of life (QoL), skin prick test, IL-4, TGF-β, IL-10, IgG4 specific HDM, IgE Specific HDM, and IFN-γ will be collected at the beginning and the end of this study.

mTOR as Mediator of Insulin Sensitivity Study

Insulin Sensitivity

The study investigates the role of mTOR in mediating enhancement of muscle insulin sensitivity following a single bout of exercise. This will be investigated in young healthy male subjects by administering the pharmacological mTOR inhibitor Rapamycin in a crossover blinded experimental setup known to enhance muscle insulin sensitivity following one-legged knee-extensor exercise.

Phase II Study of Reuse of Oxaliplatin Hypersensitivity in Gastrointestinal Tumors

Gastrointestinal Tumors

The incidence of oxaliplatin allergy reactions is between 12-15%, while the incidence of severe (grade 3-4) allergic reactions is between 0.5-2%. The purpose of this study is to prospectively investigate the incidence of oxaliplatin allergy and neurotoxicity, and to evaluate the use of effective anti-allergic and desensitization therapies to enable patients who are already allergic to oxaliplatin to complete their prescribed doses smoothly.
