The Point-Of-Care Diagnostic Landscape for Sexually Transmitted Infections (Stis)
The Point-of-Care Diagnostic Landscape for Sexually Transmitted Infections (STIs) Maurine M. Murtagh The Murtagh Group, LLC 2019 1 Introduction Sexually transmitted infections (STIs) continue to be a significant global public health issue, with an estimated 378 million people becoming ill in 2016 with one of 4 STIs: syphilis, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) (1) . In addition, more than 291 million women have a human papillomavirus (HPV) infection, which is a necessary cause of high grade cervical intraepithelial neoplasia (grade 2 or higher [CIN2+]) (1). This report considers the available and pipeline diagnostics for curable STIs, namely syphilis, CT, NG, TV, and HPV. With some exceptions, the existing diagnostics for these STIs are laboratory-based platforms, which typically require strong infrastructure and well-trained laboratory technicians. In addition, test turnaround time (TAT) is often long, requiring patients to return for test results on a subsequent clinic visit. This, in turn, leads to significant loss to follow-up. Therefore, while these laboratory-based diagnostics are effective, they may not always be suitable for use in resource-limited settings where diagnostic access and delivery are difficult. There are now a variety of tests available for use at or near the point of patient care (POC) for STIs (2). These include a wide range of rapid diagnostic tests (RDTs) for human immunodeficiency virus (HIV), hepatitis C virus (HCV) and syphilis, among others, with which it is possible to detect infection using fingerprick blood, or in some cases, oral fluid.1 In addition, other types of POC tests, including simple molecular tests for use in primary healthcare settings, have also become available recently.
