The ability to distinguish allogeneic hematopoietic cell transplantation (allo-HCT) recipients at risk for cytomegalovirus (CMV) reactivation from those who are not is central for optimal CMV management strategies. Measuring this cell mediated immunity has been proposed as a potent tool to predict those patients at highest risk of CMV reactivation and disease. This study will evaluate the ability of the T-SPOT.CMV test to predict Cytomegalovirus (CMV) reactivation in allogeneic hematopoietic cell transplantation (allo-HCT) pediatric recipients.
To evaluate feasibility of T-SPOT.CMV spot count test in allo-HCT pediatric recipients.
To evaluate association of T-SPOT.CMV spot count in the first sample collected after patient has engrafted with subsequent CMV reactivation in allo-HCT pediatric recipients.
To evaluate the correlation between T-SPOT.CMV spot count in donors with subsequent recipient CMV spot count.
To explore the relationship between recipient T-SPOT.CMV spot counts and subsequent CMV infection related morbidity and treatment outcomes among pediatric all-HCT recipients.
T-SPOT response will be measured using the results from the T-SPOT.CMV blood test in both HCT recipients and HCT donors.
A blood sample for the T-SPOT.CMV blood test will be collected from the HCT donor prior to transplant.
Blood specimens will be collected for the T-SPOT.CMV blood test from HCT recipients over the course of 6 months, starting weekly at Day +1, biweekly starting at Day +45, and monthly starting at day +120.
HCT recipient participant demographic and clinical characteristics will be collected at enrollment. Additional clinical information will be abstracted from the HCT recipient participants medical record during the study follow-up period. This will include information related to transplant history and outcome, infections, antimicrobial exposure, chemotherapy, and laboratory values related to infectious diseases and immunosuppression.
The feasibility of the T-SPOT.CMV spot count test will be evaluated once the first 30 participants enrolled on study reach day +90. If 75% of patients have at least 1 evaluable samples after engraftment (> 75,000 per microtiter wells), we will proceed with enrollment. If more >25% of patients have all their samples deemed not evaluable due to insufficient mononuclear cell count (<75,000 per microtiter wells) the study will be stopped and concluded as not feasible.

Primary Objective: 1. To evaluate the performance of the new T-SPOT.TB test and the conventional TST for screening of Latent Tuberculosis infections in patients with cancer and those unde...
The tuberculin skin test (TST) has been the gold standard for diagnosing latent tuberculosis for almost 100 years. While this test performs reasonably well in healthy, non-bacille Calmett...
Our study aims to develop a screening test for biliary atresia (BA) using dry blood spot to improve patient survival by early diagnosis. Newborn screening dry blood spot will be examined f...
The purpose of this protocol is to determine if the Welch-Allyn Spot Vision Screener (SPOT) is effective at detecting various risk factors for poor vision in developmentally delayed childr...
the aim of this study to assess the relationship and compare physiological response between spot marching exercise test and 6 minute walk test in patient with chronic obstructive pulmonary...
Fluorine-18 labeled radiopharmaceuticals undergo quality control testing for residual phase-transfer-catalyst content. The almost universally used quality-control test is a silica plate spot-test comp...
In scanned proton beam therapy systematic deviations in spot size at iso-center can occur as a result of changes in the beam-line optics. There is currently no general guideline of the spot size accur...
In spite of its pioneer use in detecting mutational processes, Drosophila still plays an important role in those studies aiming to detect and quantify the induction of DNA damage. Here we describe two...
Focal spot size partially defines spatial resolution of a computed tomography (CT) system. Many CT tubes have two focal spot sizes, with the finer one allowing more detailed imaging at the cost of pho...
A projective test used to evaluate a broad range of personality variables including pathology of thought and perception. The subject's responses to inkblot prints are scored along with subjective interpretation by the test administrator.
A test to determine the lowest sound intensity level at which fifty percent or more of the spondaic test words (words of two syllables having equal stress) are repeated correctly.
Tests of accuracy in pronouncing speech sounds, e.g., Iowa Pressure Articulation Test, Deep Test of Articulation, Templin-Darley Tests of Articulation, Goldman-Fristoe Test of Articulation, Screening Speech Articulation Test, Arizona Articulation Proficiency Scale.
Method of measuring the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy. It is used to monitor the therapy in BACTERIAL ENDOCARDITIS; OSTEOMYELITIS and other serious bacterial infections. As commonly performed, the test is a variation of the broth dilution test. This test needs to be distinguished from testing of the naturally occurring BLOOD BACTERICIDAL ACTIVITY.
Skills and strategies, unrelated to the traits a test is intended to measure, that may increase test takers' scores -- may include the effects of coaching or experience in taking tests. (ERIC Thesaurus)
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
