Filter by:A retrospective national epidemiological Swiss study was conducted to establish a real prevalence and description of congenital syphilis, and to better classify the reported congenital syphilis. Maternal risk factors to contract syphilis (i.e. socio-demographic, cultural and clinical factors) were also evaluated, in order to focus on prevention of these targeted population. Follow up of the children born from mother with syphilis during pregnancy, until age 6, was recorded to evaluate the risk of congenital syphilis following treatment of maternal syphilis.
Syphilis is an infectious disease caused by Treponema pallidum. In children, there are two different forms of this disease; acquired syphilis and congenital syphilis, which results from transplacental transmission of spirochetes. The worldwide incidence of congenital syphilis has increased in past years, probably due to inadequate control of pregnant women and lack of early diagnose and treatment in acute infected adults. This infection can have numerous and non-specific manifestations at all stages, and may simulate other diseases, which can delay diagnose if not suspected. A high number of newborns can be asymptomatic, so diagnose is confirmed or discharged by serologic testing after 6 to 10 months of age. This study will observe the clinical presentation and the laboratory of patients with CS treated.
Chagas disease and syphilis are considered a mayor public health problem worldwide. Both pathologies affect socio-economic vulnerable population and they are both transmitted congenitally, causing an alarming increasing number of infected newborns. The current diagnostic methods for these diseases are based on serology follow-up until 8 to 10 months from birth, which considering the population usually involved and their scarce resources, usually translates in loosing continuity in their controls and follow-up. Chagas prevalence in pregnant women is 4% with an incidence of Congenital Chagas disease of 1500 annual cases. From those, only 1 third are diagnosed. In the investigators and other authors experience, the detection of DNA of Trypanosoma cruzi by PCR shows an elevation of parasitemia at birth, with a peak at the first month of life. Syphilis is a re-emergent pathology, preventable and curable when diagnose is achieved early at the beginning of pregnancy.. The cost-effectiveness of performing screening for this infection is widely demonstrated, preventing high morbi-mortality for children when applied to pregnant women. For both syphilis and Chagas diagnosis, there are some studies comparing PCR follow-up with conventional serology, but none were validated and there is still need to bring more evidence in order to modify current practice. The investigators propose a sequential study of PCR for Tryipanosoma cruzi and Treponema pallidum from birth, believing this will increase sensitivity of congenital Chagas and syphilis diagnose and improve follow-up of these patients.
A dramatic rise in syphilis has been recently reported in the US between 2000-2017, which was followed also by a dramatic rise in congenital syphilis (CS). In 2017 there were 918 CS cases reported in the United States, including 64 syphilitic stillbirths. In 2017, California (CA) had one of the highest syphilis rates among women and this was accompanied by a dramatic increase in CS cases. Approximately 40% of CS cases in the United States occurred from maternal infections acquired late in gestation, missed by current-early gestation only-prenatal screening. More frequent prenatal screening late in gestation is urgently needed. However, cost considerations and operational logistic limitations preclude implementation even in high risk regions. There is an urgent need for widespread implementation of more frequent prenatal screening using alternative cost-saving screening approaches. The Syphilis-Health-Check (SHC) point-of-care (POC) test is a well validated POC-test that is already commercially available in the US, is approved by the Federal Drug Administration (FDA) and Clinical Laboratory Improvement Amendments (CLIA)-waived. POC prenatal syphilis screening late in gestation using a well validated POC-test (in addition to the standard early gestation-screening with laboratory-based tests) could provide a cost-saving complementary alternative that could benefit patients, mitigate the higher cost associated with more frequent testing, overcome operational limitations and contribute to the elimination of CS. Moreover, POC-neonatal and placental screening could provide an additional complementary safeguard approach to decrease missed/delayed CS diagnoses.
Nearly 1.5 million pregnant women are infected with syphilis each year, and it is estimated that half of them will have adverse birth outcomes. Congenital syphilis remains a major public health issue, despite the fact that maternal syphilis is easy to detect and treat. Multiple barriers impair the elimination of congenital syphilis. Syphilis is often stigmatized and of low priority, and even women attending prenatal care early are potentially facing multiple clinical barriers. The study objective is to use implementation research methods to evaluate a multifaceted intervention to increase the use of evidence-based clinical procedures to prevent congenital syphilis. The investigators will perform a facility-based, two-arm parallel cluster randomized implementation trial in the Democratic Republic of the Congo and Zambia. The intervention will be multifaceted, tailored by formative research, and include: opinion leaders, reminders, monitoring, and feedback; point-of-care rapid tests; and treatment kits to be used immediately if the rapid test is positive. Improving syphilis screening and treatment will be promoted as a key step toward improving the quality of all components of prenatal care.
