Unlabelled:
The Romanian program for the management and screening of syphilis includes the recording, follow-up, and antenatal care of pregnant women. It aims at testing all pregnant women for syphilis with the help of VDLR (Venereal Disease Research Laboratory) or RPR (Rapid Plasma Reagin) tests, and in the women with positive tests to confirm the results by treponemal tests (treponemal antibodies): THPA (Treponema Pallidum Hemagglutination), FTA-Abs (Fluorescent Treponemal Antibody with Absorption), ELISA-Captia-IgM, and Western Blotting-IgM. In the pregnant women with positive tests two doses of 2.4 million units of penicillin G benzathine were administered at 5 days interval. These pregnant women are in the evidence of a specialist (obstetrician, dermatologist), and District Department of Public Health, and required to come for another serology test in 3 months. In case they still test positive, the same treatment is applied at the beginning of the third trimester of pregnancy.
Aim:
To assess the outcome of congenital syphilis prevention programs in lasi, Romania.
Material And Methods:
In the interval 2005-2011, in the Iasi town, 84 RPR positive pregnant women were recorded. There was no significant difference in the number of pregnant women residing in urban as compared to rural areas. Most of these women were from poor social environments and had a low level of education. The diagnosis of acquired syphilis was made by serological tests as most pregnant women presented in the period of syphilis latency, being asymptomatic. All pregnant women followed the treatment, and were tested periodically. Ultrasound examination was normal in all women (no changes suggestive of fetal malformations).
Results:
Free clinical, laboratory, and ultrasound investigations, history taking, psychological assessment, sex education, rapid identification of contacts of known patients, follow-up of the interaction between health care providers and syphilitic pregnant women, booklets, and leaflets altogether made that in the last 3 years (2008-2010) no new case of congenital syphilis to be reported in the study area.
Conclusions:
Encouraging women to attend antenatal care early in their pregnancy is essential, this way all pregnancy-related problems (syphilis included) could be managed.
