Swab-Yourself Trial With Economic Monitoring and Testing for Infections Collectively (SYSTEMATIC): Part 2. A Diagnostic Accuracy and Cost-effectiveness Study Comparing Rectal, Pharyngeal, and Urogenital Samples Analyzed Individually, Versus as a Pooled Specimen, for the Diagnosis of Gonorrhea and Chlamydia.

Background: Sexual history does not accurately identify those with extragenital Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), so universal extragenital sampling is recommended. Nucleic acid amplification tests (NAATs) are expensive. If urogenital, plus rectal and pharyngeal, samples are analyzed, the diagnostic cost is trebled.

Swab-yourself Trial With Economic Monitoring and Testing for Infections Collectively (SYSTEMATIC): Part 1. A Diagnostic Accuracy and Cost-effectiveness Study Comparing Clinician-taken vs Self-taken Rectal and Pharyngeal Samples for the Diagnosis of Gonorrhea and Chlamydia.

Background: Urogenital testing misses extragenital Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT). Extragenital self-sampling is frequently undertaken despite no robust randomized, controlled trial evidence of efficacy. We compared clinician-taken rectal and pharyngeal samples with self-taken samples for diagnostic accuracy and cost in men who have sex with men (MSM) and in females.

Serological follow-up of infants born to mothers with positive syphilis serology - real-world experiences.

The 2008 UK syphilis guideline recommends infants born to women with any positive syphilis serology be followed up until both treponemal and nontreponemal tests are negative to exclude congenital syphilis, whereas Centers for Disease Control and Prevention guidelines recommend using only nontreponemal tests. Historically, we had low infant follow-up rates with no coherent pathways. We initiated a change in multidisciplinary team practice of infant testing for syphilis in 2011 and evaluated the results before and after by retrospective review of testing of infants born to women with positive syphilis serology between 2005 and 2012.

Adverse pregnancy outcomes following syphilis treatment in pregnancy in the UK.

Syphilis infection in pregnancy is known to cause a number of severe adverse pregnancy outcomes, including second-trimester miscarriage, stillbirth, very pre-term delivery and neonatal death, in addition to congenital syphilis. A retrospective review of women with positive syphilis serology and a pregnancy outcome between 2005 and 2012 in Leeds, UK, was performed. In all, 57 cases of positive syphilis serology in pregnancy were identified: 24 with untreated syphilis treated in the current pregnancy (Group 1); seven with reported but unconfirmed prior treatment who were retreated (Group 2); and 26 adequately treated prior to pregnancy (Group 3).
