          Abstract

          OBJECTIVE: To perform a systematic review and meta-analysis of reported estimates of the association between gestational syphilis (GS) and stillbirth in the Americas region. METHODS: Cochrane Library, Embase, LILACS, MEDLINE/PubMed, PLOS, and ScienceDirect were searched for original research studies quantifying the relationship between GS and stillbirth in the region. A final sample of eight studies was selected. A cumulative meta-analysis plus four subgroup meta-analyses of study data on the association between maternal syphilis during pregnancy and stillbirth were conducted. The four meta-analyses were based on 1) definition of cases and the control; 2) syphilis treatment (presence or absence, effective or ineffective); 3) definition of stillbirth as "showing no signs of life at birth"; and 4) definition of stillbirth based on low birth weight and gestational age. Random-effects metaanalyses were used to calculate pooled estimates of stillbirth with exposure to GS, and each subgroup analysis was tested for heterogeneity. RESULTS: Women with GS had increased odds of stillbirth (pooled odds ratio (OR): 6.87; 95% confidence interval: 2.93, 16.08). There was considerable heterogeneity across the eight studies (percentage of variance (I²) = 95). The funnel plot was not statistically significant, pointing to a lack of publication bias. Increased odds of stillbirth among pregnant women with syphilis were also seen in all four subgroup meta-analyses. CONCLUSIONS: GS is a major contributing factor for stillbirths in the Americas. Interventions targeting GS are highly cost-effective and, along with high-quality point-of-care testing, should be implemented across the region to help reach the goal of eliminating congenital syphilis.

          OBJETIVO: Llevar a cabo una revisión sistemática y metanálisis de los cálculos notificados de la asociación entre sífilis gestacional (SG) y mortinatalidad en la Región de las Américas. MÉTODOS: Se realizó una búsqueda en Cochrane Library, Embase, LILACS, MEDLINE/PubMed, PLOS y ScienceDirect de estudios de investigación originales que cuantificaran la relación entre la SG y la mortinatalidad en la Región de las Américas. Se seleccionó una muestra final de ocho estudios. Se efectuaron un meta-nálisis acumulativo y cuatro metanálisis de subgrupo de los datos de estudio sobre la asociación entre sífilis materna durante el embarazo y mortinatalidad. Los cuatro metanálisis se basaron en 1) la definición de casos y del control; 2) el tratamiento de la sífilis (presencia o ausencia, eficaz o ineficaz); 3) la definición de mortinatalidad como "ausencia de signos de vida al nacer"; y 4) la definición de mortinatalidad basada en el bajo peso al nacer y la edad gestacional. Se emplearon metanálisis de efectos aleatorios para calcular las estimaciones acumuladas de mortinatalidad con exposición a la SG, y se comprobó la heterogeneidad de cada uno de los análisis de subgrupo. RESULTADOS: Las mujeres con SG presentaron mayores probabilidades de mortinatalidad (razón de posibilidades [OR] acumulada: 6,87; IC de 95%: 2,93-16,08). Se observó una heterogeneidad considerable en los ocho estudios (porcentaje de variación [I2] = 95). El gráfico en embudo no fue estadísticamente significativo, lo que indica una ausencia de sesgo de publicación. En los cuatro metanálisis de subgrupo, también se observaron mayores probabilidades de mortinatalidad en las mujeres embarazadas con sífilis. CONCLUSIONES: La SG es un importante factor contribuyente a la mortinatalidad en la Región de las Américas. Las intervenciones dirigidas a la SG son altamente eficaces en función de los costos y deben ejecutarse en toda la región, junto con las pruebas diagnósticas de alta calidad en el lugar de asistencia, para ayudar a alcanzar la meta de eliminación de la sífilis congénita.

          Syphilis in pregnancy in Tanzania. I. Impact of maternal syphilis on outcome of pregnancy.

          To measure the impact of maternal syphilis on pregnancy outcome in the Mwanza Region of Tanzania, 380 previously unscreened pregnant women were recruited into a retrospective cohort at delivery and tested for syphilis. Stillbirth was observed in 18 (25%) of 73 women with high-titer active syphilis (i.e., women with a rapid plasma reagin titer > or = 1 :8 and a positive Treponema pallidum hemagglutination assay or indirect fluorescent treponemal antibody test result), compared with 3 (1%) of 233 uninfected women (risk ratio [RR], 18.1; P<.001). Women with high-titer active syphilis were also at the greatest risk of having low-birth-weight or preterm live births (RR, 3.0 and 6.1, respectively), compared with women with other serological stages of syphilis. Among unscreened women, 51% of stillbirths, 24% of preterm live births, and 17% of all adverse pregnancy outcomes were attributable to maternal syphilis. Syphilis continues to be a major cause of pregnancy loss and adverse pregnancy outcome among women who do not receive antenatal syphilis screening and treatment.

              The infectious origins of stillbirth.

              Our objective was to determine the relationship between various types of perinatal infections and stillbirths. By use of various textbooks on perinatal infections, multiple MEDLINE searches, and the reference list of all appropriate manuscripts, the appropriate English language literature was reviewed to define the relationship between various perinatal infections and stillbirths. Infection may cause stillbirth by a number of mechanisms, including direct infection, placental damage, and severe maternal illness. A large variety of organisms have been associated with stillbirth, including many bacteria, viruses, and protozoa. In developed countries, between 10% and 25% of stillbirths may be caused by an infection, whereas in developing countries, which often have much higher stillbirth rates, the contribution of infection is much greater. Ascending bacterial infection, both before and after membrane rupture, with organisms such as Escherichia coli, group B streptococci, and Ureaplasma urealyticum is usually the most common infectious cause of stillbirth. However, in areas where syphilis is very prevalent, up to half of all stillbirths may be caused by this infection alone. Malaria may be an important cause of stillbirth in women infected for the first time in pregnancy. The two most important viral causes of stillbirth are parvovirus and Coxsackie virus, although a number of other viral infections appear to be causal. Toxoplasma gondii, leptospirosis, Listeria monocytogenes, and the organisms that cause leptospirosis, Q fever, and Lyme disease have all been implicated as etiologic for stillbirth. Because infection-related stillbirth is relatively rare in developed countries, and those that do occur are caused by a wide variety of organisms, reducing this etiologic component of stillbirth much further will be difficult. However, in certain developing countries, the stillbirth rate is so high and the infection-related component so great that achieving a substantial reduction in stillbirth should be possible simply by reducing maternal infections.
