简要总结
This is an observational study in which data from women with Chagas disease who will take or have already taken nifurtimox during pregnancy and the impact on their babies are studied.
Chagas disease is an inflammatory, infectious disease caused by the parasite Trypanosoma cruzi. This parasite is mainly spread by insects called triatomine bug. If Chagas disease is left untreated, it can later cause e.g. serious heart and digestive problems.
Nifurtimox has been used for more than 50 years to treat Chagas disease in children and adults.
It is not recommended to be used during pregnancy as data from animal studies indicate that it may harm the baby. Currently, there are not enough data to know if this is also the case in humans.
In this study, researchers want to collect data on the safety of nifurtimox use in pregnant women. To do this, researchers will collect the following information:
- Birth defects (abnormal and problematic structures or functions, a child is born with)
- Pregnancy outcomes (like live birth, preterm birth, still birth/death of the unborn baby, miscarriage, or abortion)
- Certain health problems of the child up to 12 months of age
- Certain health problems of the women experienced during pregnancy The data will be collected from different sources including telephone calls with the women or their doctor, CRFs (case reprt forms) or from medical records The researchers will compare the proportion of children with birth defects, pregnancy outcomes or certain health problems of the child or the women during pregnancy with available data on these outcomes in the general population.
The study will run for approximately 10 years.

研究组 & 干预措施
Pregnant women exposed to nifurtimox
The study will examine the effects of nifurtimox on fetuses, neonates and infants through 12 months of age who were exposed to nifurtimox in utero and maternal complications of pregnancy in women who were exposed to at least one dose of nifurtimox during pregnancy.
干预措施: Nifurtimox (BAYA2502) (Drug)
结局指标
主要结局
Major Congenital Malformations (birth defects)
时间窗: Up to pregnancy week 40
1. any major structural defect diagnosed with signs/symptoms, using the selected major congenital anomalies list extracted from the Birth defects surveillance: a manual, CDC. 2. on a case-by-case basis, through evaluator review and agreement from external advisors (if required), any structural defect (that satisfy criterion 1 or 2) detected in the prenatal evaluation of a pregnancy or in the gross or pathologic examination of an abortus, fetus, or deceased infant will be included, if available, to increase the sensitivity of pregnancy study monitoring
