The primary objective is to determine the proportion of positive QuantiFERON-TB Gold Plus tests at pre-employment screening. Secondary objectives are to identify factors associated with a positive test, to describe the practical consequences of screening, including chest X-ray, diagnosis of latent tuberculosis infection and initiation of preventive treatment, and to estimate the cost of systematic screening.",[25],"Latent Tuberculosis Infection","NOT_YET_RECRUITING","2026-05-20",{"date":29,"type":30},"2026-05-27","ACTUAL",{"date":32,"type":21},"2026-06-01",{"date":34,"type":21},"2026-08-30",{"name":36,"class":37},"Centre Hospitalier Universitaire de Nice","OTHER",1,{"id":40,"slug":41,"hasResults":11,"nctId":42,"briefTitle":43,"officialTitle":44,"acronym":4,"eligibilityCriteria":45,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":46,"enrollmentInfo":47,"targetDuration":4,"studyType":22,"phases":4,"briefSummary":49,"conditions":50,"keywords":4,"overallStatus":26,"whyStopped":4,"lastUpdateSubmitDate":53,"lastUpdatePostDateStruct":54,"startDateStruct":56,"completionDateStruct":58,"leadSponsor":60,"locationsCount":4},"100609162","prevalence-of-latent-tuberculosis-infection-among-hemodialysis-patients-100609162","NCT07210970","Prevalence of Latent Tuberculosis Infection Among Hemodialysis Patients","Study of The Prevalence of Latent Tuberculosis Infection Among Hemodialysis Patients Using Tuberculin Skin Test at Sohag University Hospital","Inclusion Criteria:\n\nAge ≥ 18 years Patients on regular hemodialysis Able and willing to provide informed consent\n\n\\-\n\nExclusion Criteria:\n\n* active TB patients","100 Years",{"count":48,"type":21},200,"This observational cross-sectional study aims to determine the prevalence of latent tuberculosis infection (LTBI) among patients undergoing regular hemodialysis at Sohag University Hospital, using the tuberculin skin test (TST).
