“…The activation of the viral replication during the third quarter of pregnancy presents an important risk of 80% to 90% of viral transmission to the child. 32 The vertical HBV transmission rate that we found (21.4%) is defi nitely higher than those obtained respectively by Wiseman et al (2009) 33 in Australia (3.0%), and by Lima and Viana (2009) 34 in Brazil (1.0%). However, similar rates were obtained by Ilboudo et al (2002) 25 in Ouagadougou (25.0%); Koedijk et al (2007) 35 report in Netherland that 40% of chronic HBV infections were transmitted from mother to child in an area not endemic for HIV, but we do not know what happen in Burkina Faso.…”

“…1,2 Among the modes of infection of the Human Immunodefi ciency Virus (HIV) and Hepatitis B Virus (HBV), the mother-tochild vertical transmission (MTCT) is a wellestablished fact. 34 This transmission is carried out in the intrauterine life by mother-foetal micro-transfusion, during the delivery by contact with maternal blood and vaginal secretions, or during breast feeding. 4,5 In the tropical zones of Africa in the South of the Sahara, HIV/AIDS, by its morbidity and mortality, constitutes a real problem of public health.…”

We declare no confl ict of interest. ABSTRACTThe coinfection of HIV and hepatitis B virus (HBV) and their vertical transmission constitute a public health problem in sub-Saharan countries of Africa. The objectives of this research are: i) identify the pregnant women that are coinfected by HIV and HBV at Saint Camille Medical Centre; ii) use three antiretroviral drugs (zidovudine, nevirapine and lamivudine) to interrupt the vertical transmission of HIV and HBV from infected mothers; and iii) use the PCR technique to diagnose children who are vertically infected by these viruses in order to offer them an early medical assistance. At Saint Camille Medical Centre, 115 pregnant women, aged from 19 to 41 years, were diagnosed as HIV-positive and, among them, 14 coinfected with HBV. They had at least 32 weeks of amenorrhoea and all of them received the HAART, which contained lamivudine. Two to six months after childbirth, the babies underwent PCR diagnosis for HIV and HBV. The results revealed that, among these mothers, 64.4% were housewives, 36.5% were illiterates, and only 1.7% had a university degree. The rate of vertical transmission of HIV and HBV was 0.0% (0/115) and 21.4% (3/14), respectively. The 3 mothers who transmitted the HBV to their children had all HBsAg, HbeAg, and HBV DNA positive. An antiretroviral therapy that in addition to zidovudine and nevirapine includes lamivudine could, as in the present study, block or reduce the vertical transmission in HIV positive pregnant women who are coinfected with HBV.

“…A 10% HIV-1/HCV co-infection prevalence was observed in our study, which is higher than the HCV prevalence among general pregnant women (0.1%-2.7%) reported in other regions of Brazil (Costa et al 2009, Lima & Viana 2009). There are very few reports of HIV/HCV co-infection in Brazil.…”

“…But HBV infection prevalence among pregnant women living in Nigeria, Uganda, Ethiopia, Mauritania, Mali, Yemen and South Africa was much higher than the prevalence among Iranian pregnant women. In addition, Pakistani, Libyan and Turkish pregnant women were slightly more infected than Iranian women (4,7,(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51). Higher infection rates in most African countries and lower rates among women in most European countries indicates the effect of health promotion and vaccine coverage on the patterns of infection.…”

Background: Hepatitis B infection can be transmitted both vertically and horizontally. Although the universal neonatal vaccination and catch up vaccination of teenagers along with targeted vaccination of at risk population have decreased the prevalence of HBV infection in Iran dramatically, there is still risk of vertical transmission with subsequent chronic liver disease and hepatocellular carcinoma. This study aims to estimate the prevalence of latent HBV infection among Iranian pregnant women using metaanalysis method.Data Sources: Papers written in Persian or English were identified during a comprehensive search within five national and four international main databases. Study Eligibility Criteria and Participants:Studies reported the HBV infection prevalence among Iranian pregnant women and provided enough quality scores were selected for this meta-analysis. Methods:After a systematic review of national and international databases, duplicated and irrelevant studies were excluded. Standard error of the infection prevalence was calculated based on the binomial distribution. Because of the significant heterogeneity observed among the results, random effects model was applied to combine the results of the primary studies. Moreover, sensitivity analysis and meta-regression models were used to detect the sources of this heterogeneity.Results: At final step of the systematic search, 18 papers entered into the meta-analysis investigating 24853 pregnant women. Prevalence of HBV infection among Iranian pregnant women was estimated as 1.2% (95% confidence interval: 0.9 -1.6). Among different risk factors assessed, only familial history in four studies out of five relevant evidences was statistically significant. Conclusions:HBV infection prevalence among Iranian pregnant women is low and familial history is its major determinant.
