Few data are available on the risk of congenital malformation with first trimester exposure to the newer therapies telbivudine (FDA category B) and entecavir (FDA Category C). The XL765 outcome of the pregnancy should be reported to the Interferon Pregnancy and Antiretroviral Pregnancy Registries. 6.1.5 As there is no evidence of any adverse effect on maternal or neonatal health if women become pregnant while taking ART active against HBV, treatment should be continued. Grading: 1C For

tenofovir, emtricitabine and lamivudine, APR [49] and the Development of Antiretroviral Therapy Study (DART) have not identified any increased risk in prevalence or any specific pattern of anomaly, even when administered in the first trimester. Hence, when a patient becomes pregnant on an anti-HBV viral agent as part of their HAART (tenofovir, lamivudine or emtricitabine), as for HIV management, HAART should be continued. This is because the potential risk

to the fetus from drug exposure is outweighed by that of a hepatitis flare or liver disease progression if the drug(s) were to be discontinued in addition to HIV virological rebound and risk of MTCT. Because entecavir has activity against HIV, it is not recommended unless given with active HAART in a coinfected patient. Moreover, it has http://www.selleckchem.com/products/Sunitinib-Malate-(Sutent).html been found to have significant carcinogenic potential in animal studies and therefore its use as an antiviral drug for HBV during pregnancy should be avoided. Lamivudine has been extensively used, as has tenofovir and to a lesser extent emtricitabine, for the treatment of HIV mono-infection during pregnancy, and lamivudine and telbivudine have been used in HBV mono-infected pregnant women and all have been found to be safe. There are limited data on adefovir use in pregnancy and it is not recommended. Where it is being used in a woman for management of HBV but who does not require HIV treatment, this should be switched to tenofovir incorporated into her HAART regimen. In the context of coinfection during pregnancy where HAART is indicated, there is unlikely to be a situation where it would

be used instead of tenofovir. There is no Sirolimus manufacturer evidence of any adverse effect on maternal health if women become pregnant while taking tenofovir, lamivudine or emtricitabine: these drugs are recommended as NRTI choices in national [169] and international guidelines [154]. 6.1.6 In all HAV non-immune HBV coinfected women, HAV vaccine is recommended after the first trimester as per the normal schedule (0 and 6–12 months) unless the CD4 cell count is <300 cells/μL, when an additional dose may be indicated. Grading: 1D Immunization for HAV uses inactivated vaccines. Data for HAV vaccine in pregnancy are limited. Nevertheless, several guidelines indicate that pregnancy is not a contraindication for HAV immunization, including in HBV coinfected pregnant women [170],[171].
