Use of Abbott RealTime CT/NG to Detect Chlamydia Trachomatis [CT] & Neisseria Gonorrhoeae [NG] in Men Who Have Sex With Men [MSM]
Julius Schachter, PhD, (Department of Laboratory Medicine, University of California, San Francisco) and Susan S. Philip, MD MPH (Department of Medicine, University of California, San Francisco) are conducting a study to evaluate the Abbott RealTime CT/NG polymerase chain reaction [PCR] assay (which is a nucleic acid amplification test [NAAT]) for detecting two sexually transmitted bacteria, Chlamydia trachomatis [CT] and Neisseria gonorrhoeae [NG], using urine samples and swabs from the throat and rectum of men who have sex with men [MSM]. Using this test on these swabs is experimental because it has not been approved by the Food & Drug Administration.
|Study Design:||Observational Model: Cohort
Time Perspective: Cross-Sectional
|Official Title:||Evaluation of Abbott RealTime CT/NG for the Detection of Chlamydia Trachomatis [CT] & Neisseria Gonorrhoeae [NG] From the Pharynx, Rectum & Urethra of Men Who Have Sex With Men [MSM]|
- Subject's infected-status as determined by the nucleic acid amplification assays performed. [ Time Frame: 1 day - (At clinic visit) ] [ Designated as safety issue: No ]This is a single-point prevalence assessment done when subjects present at the STD clinic for routine STD screening. Subjects are not followed beyond the clinic visit.
Biospecimen Retention: Samples With DNA
clinician-collected rectal and pharyngeal swabs along with FCUs
|Study Start Date:||June 2012|
|Estimated Study Completion Date:||May 2013|
|Estimated Primary Completion Date:||May 2013 (Final data collection date for primary outcome measure)|
For each subject enrolled in the study, the following clinical data information will be obtained: 1) reason for exam, 2) subject's signs and symptoms and 3) clinical assessment.
For each subject enrolled in the study, two clinician-collected pharyngeal swabs, two clinician-collected rectal swabs, and a first catch urine specimen (approximately 25 ml) will be obtained. The collection order of the clinician-collected swabs will be randomized.
Two pharyngeal swabs will be tested at the research laboratory using: 1) APTIMA COMBO 2® [AC2](Gen-Probe Inc, San Diego, CA); and 2) Abbott RealTime CT/NG [RealTime](Abbott Molecular, Des Plains, IL). Two rectal swabs will be tested at the research laboratory using: 1) AC2; and 2) RealTime.
A first-catch urine [FCU] specimen will be split out at San Francisco Department of Public Health laboratory and sent to the Chlamydia Research Laboratory for analysis using: 1)AC2; and 2) RealTime.
All NAAT specimens are collected in the manufacturer's recommended NAAT transport medium. After specimen processing, samples will be frozen at -70ºC for discrepant analysis.
