Evaluation of Self-Collected Vaginal Swab, First Void Urine, and Endocervical Swab Specimens for the Detection of Chlamydia Trachomatis and Neisseria Gonorrhoeae in Adolescent Females
چکیده انگلیسی

ObjectiveTo assess the concordance of self-obtained vaginal swabs (SVS), first void urine samples (FVU) and provider-collected endocervical swabs (PES) for the detection of Chlamydia trachomatis (CT) and Neisseria gonorrhea (NG) in adolescents.MethodsA total of 342 adolescent women and 1080 baseline and semi-annual visits were analyzed. FVU, SVS and PES were collected at each biannual visit. All specimens were tested by BDProbeTec ET™ Amplified DNA Assay. Sensitivity, specificity, positive predictive value (PPV) negative predictive value (NPV) and kappa coefficient were calculated to evaluate the ability to identify possible infected cases using samples from three anatomic sites and the test agreement between any two of these three specimen types. Positive results from at least two of the three specimens collected from same subject at the same study visit was considered true positive.ResultsThe positivity rates for CT and NG were 26.6 and 11.7 per 100 women respectively. The sensitivities of SVS, FVU and PES for detecting CT were 97.3%, 89.2% and 90.1% respectively. For the detection of NG, the sensitivities of the three sampling methods were 100%, 88.6% and 95.5% respectively. The specificities were between 94.7% and 99.7% for both CT and NG. Kappa coefficients of CT test results were 0.89, 0.88 and 0.83 for specimen pairs SVS vs PES, SVS vs FVU and PES vs FVU respectively. For the detection of NG, kappa coefficients were 0.91, 0.87 and 0.91 for these three pairs (all P < 0.0001). Kappa > 0.75 is considered excellent agreement between specimens.ConclusionThere were strong agreements among SVS, PES and FVU specimens on the detection of CT and NG infections in adolescent females using nucleic acid amplification test. SVS represented as high as or more sensitive an approach for detecting both CT and NG compared to PES. Although FVU was the least sensitive sampling method, it is also the least invasive method. Thus SVS and FVU may provide a reliable alternative to endocervical specimens for CT and NG screening.
