Objective: To analyze the association between different treatment timings and adverse neonatal outcomes (premature birth, death, congenital syphilis) in syphilis-infected pregnant women. Methods: The National Management Information System for Prevention of HIV, Syphilis and HBV Mother-to-Child Transmission was used to collect information on the detection and treatment of syphilis-infected pregnant women and their newborns in Guangdong Province from October 2011 to December 2021. According to the gestational weeks of syphilis-infected pregnant women receiving penicillin treatment for the first time, they were divided into four groups: treatment in the first trimester, treatment in the second trimester, treatment in the third trimester, and no treatment during pregnancy. Multivariate logistic regression was used to analyze the association between different treatment timings and adverse neonatal outcomes in syphilis-infected pregnant women. Results: A total of 22 483 syphilis-infected pregnant women were included. The number of pregnant women who started treatment in the first trimester, second trimester, and third trimester and did not receive treatment during pregnancy were 4 549 (20.23%), 8 719 (38.78%), 2 235 (9.94%) and 6 980 (31.05%), respectively. Compared with pregnant women who started treatment in the first trimester, pregnant women who did not receive anti-syphilis treatment during pregnancy had increased risks of neonatal preterm birth (OR=1.42, 95%CI: 1.24-1.62), death (OR=4.27, 95%CI: 1.64-14.69) and congenital syphilis (OR=12.26, 95%CI: 6.35-27.45). At the same time, the risk of congenital syphilis in the newborns of pregnant women who started anti-syphilis treatment in the second trimester (OR=2.68, 95%CI: 1.34-6.16) and third trimester (OR=6.27, 95%CI: 2.99-14.80) also increased. Conclusion: Early initiation of anti-syphilis treatment during pregnancy in patients with syphilis can improve neonatal outcomes.

OBJECTIVETo investigate the current status of contact tracing among pregnant women infected with syphilis and to analyze the associated factors from patients' perspective.

METHODSPregnant women who aged 18 years old, receiving prenatal care services in Shenzhen, diagnosed with syphilis according to national diagnostic criteria (WS 273-2007) from 2008 to 2011 were recruited and the total number was 3 551. Information of both pregnant women (including demographic information, laboratory results, syphilis diagnosis, and personal life history) and their partners (including results of partner tracing and laboratory examination) were collected with structured questionnaire by face-to-face interview. Multivariate non-conditional logistic regression model was applied to analyze the factors associated with partners' contract tracing. Odds ratio (OR) and its 95% confidential interval (95%CI) were calculated.

RESULTSThe average age was 28.72 among recruited 3 551 syphilis-infected pregnant women, with standard deviation of 5.21 and range of 18 to 40. Totally 2 550 partners attended antenatal clinics and received syphilis examination, with a contact tracing rate of 71.81%. The OR(95%CI) was 1.70(1.26-2.30) for pregnant women with college or above education when comparing with those with senior high school or below education. The OR(95%CI) was 0.57(0.45-0.71) for those unmarried or divorce when comparing with those married. The OR (95% CI) was 0.73(0.56-0.94) and 0.65(0.53-0.81) for those screened in 28-36 gestational weeks and those screened in >36 gestational weeks or right before delivery separately, when comparing with those screened in ≤27 gestational weeks. The OR (95% CI) was 1.45(1.14-1.84) for those having received sufficient treatment before pregnancy when comparing with those diagnosed with latent syphilis. The OR(95%CI) was 0.31 (0.24-0.39) for those having no treatment or not standardized treatment when comparing with those having standardized penicillin treatment. The OR(95%CI) was 0.53 (0.43-0.65) for those terminating the pregnancy when comparing with those giving birth to a baby. The OR(95%CI) was 1.24 (1.05-1.46) for those having two or more love histories when comparing with those having only one love history. The OR(95%CI) was 4.74 (3.54-6.35) for those intending to disclose the serostatus to their partner when comparing with those showing unwillingness to disclose the serostatus.

CONCLUSIONThe successful rate of contact tracing among pregnant women infected with syphilis was high. The implementation of contact tracing may be affected by many factors, including patients' education levels, marital status, gestational weeks of screening, stage of syphilis, treatment status, outcome of pregnancy, number of love histories, and willingness of serostatus disclosure.

OBJECTIVETo demonstrate the effectiveness of prevention of mother-to-child HIV, syphilis, and hepatitis B transmission among pregnant women in Dehong prefecture, Yunnan province, China from 2011 to 2013.

METHODSData were collected mainly from the continuous HIV surveillance system and prevention of mother-to-child transmission (PMTCT) reporting system of Dehong prefecture, and supplemented by annual reported data on HIV, syphilis, and hepatitis B PMTCT to know the general demographic characteristics, HIV testing and counseling service, PMTCT service, and other medical services. Data were presented as absolute numbers and proportions.

RESULTSFrom 2011 to 2013, the number of pregnant women participating in HIV, syphilis, and hepatitis B testing in Dehong prefecture increased and the HIV testing rates were 99.2% (18 694/18 854), 99.9% (22 047/22 060) and 99.9% (21 751/21 756), the syphilis testing rates were 56.0% (10 550/18 854), 99.6% (21 980/22 060) and 99.9% (21 751/21 756), and the hepatitis B testing rates were 60.2% (11 358/18 854), 99.6% (21 974/22 060) and 99.9% (21 751/21 756). From 2011 to 2013, the HIV positive rates were 0.87% (327/37 787),0.82% (319/38 817) and 0.85% (315/37 261), the syphilis positive rates were 0.05% (10/18 520),0.12% (43/36 817) and 0.11% (40/35 888), the hepatitis B positive rates were 2.46% (456/18 520), 2.23% (794/35 547) and 2.14% (739/34 468), respectively. The rates of HIV-positive pregnant women giving birth in hospitals were 99.2% (128/129), 100.0% (141/141) and 100.0% (141/141). From 2011 to 2013, the proportions of HIV-positive pregnant women receiving antiretroviral therapy were 99.2% (128/129), 99.3% (140/141) and 99.3% (140/141), respectively. And the treatment rate of syphilis-positive pregnant women were 71% (5/7), 89% (16/18) and 97% (32/33). The rates of hepatitis B immunoglobulin injection among new-borns of hepatitis B-positive pregnant women were 92.9% (263/283), 99.7% (612/614) and 99.4% (629/633). The estimated rates of mother-to-child transmission of HIV were 2.28%, 2.30% and 3.00%, respectively.

CONCLUSIONThere was an increasing trend of HIV, syphilis, and hepatitis B testing rate and the positive rate kept at a low level. The proportions of HIV-positive pregnant women receiving HIV, syphilis, and hepatitis B PMTCT services increased annually, while the proportion of HIV MTCT kept at an overall low level from 2011 to 2013, which indicated its effectiveness of HIV PMTCT work during recent years in Dehong prefecture,Yunnan province, China.

OBJECTIVETo analyze the risk factors for maternal and perinatal syphilis infections in Guangzhou.

METHODSWe collected the data of pregnant women with perinatal syphilis infections from the Obstetrics Critical Care Center, Third Affiliated Hospital of Guangzhou Medical University during the period from January, 2009 to April, 2013.

RESULTSin the 64 253 pregnant women surveyed, the mean annual incidence of syphilis during pregnancy was 0.255% within the surveyed period. In women with syphilis during pregnancy, those receiving normal anti-syphilis treatment had a significantly lower rate of neonatal serological syphilis positivity and those without treatment (55.81% vs 100%); the serological syphilis positivity rates differed significantly between neonates with parental syphilis infection and those without (54.348% vs 20%). Of the women with syphilis during pregnancy, 82.14% reported syphilis of the spouse, 80.36% were floating population, and 78.57% had previous multiple pregnancies.

CONCLUSIONThe incidence of syphilis during pregnancy shows a linear growth in the 5 past years in Guangzhou. Maternal syphilis during pregnancy without proper anti-syphilis treatment and vertical transmission are the most important risk factors for neonatal syphilis. A syphilis spouse, floating population, and multiple pregnancies all contribute to neonatal syphilis.

BACKGROUNDFollowing the increased human immunodeficiency virus (HIV) notification (infection) rates via sexual transmission and increased abuse of new synthetic drugs instead of heroin in China, a study on HIV infections and risk factors among synthetic drugs and heroin users in Beijing was conducted to provide a cue for further development of targets and strategies of HIV/AIDS control and prevention for different drug populations.

METHODSA total of 428 subjects including 224 heroin users and 204 new synthetic drug users was recruited from communities in Beijing by convenience sampling. A χ(2) test was used to compare HIV and syphilis infections between the two subpopulations. Logistic regression models were used to evaluate factors related to HIV, syphilis infections and abuse of synthetic drugs.

RESULTSUnbalanced distributions of demographics were detected between the two subpopulations. Compared with heroin users, most users of synthetic drugs were migrants, single and of younger age (age ≤ 30 years). Ten HIV infections and twenty-four syphilis infections were confirmed among 428 subjects. No significant difference in HIV infection was found between the two subpopulations (crude odds ratio (OR) = 0.46, 95% confidence interval (CI): 0.07 - 15.80 and adjusted odds ratio (AOR) = 1.26, 95%CI: 0.09 - 18.28) while four times as many syphilis infections were identified among users of synthetics drugs (AOR = 3.92, 95%CI: 1.06 - 14.56). HIV and syphilis infections appeared to work synergistically. The migrants who were of Han ethnicity, single and who had stayed in Beijing for more than six months were more likely to abuse synthetics drugs.

CONCLUSIONSThe new synthetic drug users and heroin users are different subpopulations. We optimistically speculate that HIV has not yet been introduced into the former in Beijing, but considering higher syphilis infections in synthetic drug users and the role of syphilis in HIV infection, synthetic drug users, as a possible and important driver of the HIV/AIDS epidemic in Beijing, should be paid more attention in HIV prevention and control strategies.
