Data are lacking on factors that may impact conception-related decision-making among individuals living with HIV. This study's aim was to shed light on these considerations. Participants were invited to complete a survey on preconception considerations. A rank-ordered logit model was fit to estimate the relative importance of listed consideration factors; the interaction of HIV status and the factors was assessed. Fifty-nine participants living with HIV and 18 partners (11 HIV-negative participants and 7 living with HIV) were included. Risk of vertical and horizontal HIV transmission and the effect of antiretroviral therapy on the fetus were the top considerations. However, individuals living with HIV prioritized vertical transmission, whereas HIV-negative participants prioritized horizontal transmission. Other factors of importance were probability of conception, stress of trying to conceive, cost associated with fertility clinics, and stigma associated with certain conception methods. This study builds our understanding of the preconception considerations for people living with HIV.

Objectives: There is speculation, but there are few data, on the high rates of unintended pregnancies in HIV-positive women. We investigated rates and correlates of unintended pregnancies among HIV-positive women of reproductive age., Methods: A cross-sectional study was conducted with recruitment stratified to match the geographical distribution of HIV-positive women of reproductive age (18-52 years) living in Ontario, Canada. Women, recruited from 38 sites between October 2007 and April 2009, were invited to complete a 189-item self-administered survey. This analysis focused on questions relating to pregnancy and whether the last pregnancy was intended. Logistic regression models were fitted to calculate unadjusted and adjusted odds ratios of correlates of unintended pregnancies occurring after HIV diagnosis. Happiness with unintended pregnancies was also assessed., Results: The median age at the time of the survey of the 416 participating HIV-positive women who were previously pregnant (53% before and 47% after HIV diagnosis) was 38 years [interquartile range (IQR) 33-44 years] and their last pregnancy was a median of 8 years (IQR 3-14 years) prior to the survey (n=283). Fifty-nine per cent were born outside Canada and 47% were of African ethnicity. Of the 416, 56% [95% confidence interval (CI) 51-61%] identified that their last pregnancy was unintended (57% before and 54% after HIV diagnosis). In the multivariable model, significant correlates of unintended pregnancy after HIV diagnosis were: marital status (P=0.01) and never having given birth (P=0.01). Women were less happy if their pregnancy was unintended (P<0.01)., Conclusions: The prevalence of unintended pregnancy was high in this cohort. Pregnancy planning programmes are needed for this population to decrease fetal and maternal complications and reduce vertical and horizontal transmission., (© 2011 British HIV Association.)

Symptomatic and asymptomatic bacteriuria is common in pregnant women. A history of previous urinary tract infections and low socioeconomic status are risk factors for bacteriuria in pregnancy. Escherichia coli is the most common aetiologic agent in both symptomatic and asymptomatic infection and quantitative culture is the gold standard for diagnosis. Treatment of asymptomatic bacteriuria has been shown to reduce the rate of pyelonephritis in pregnancy and therefore screening for and treatment of asymptomatic bacteriuria has become a standard of obstetrical care. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of low birth weight, but the methodological quality of the studies limits the strength of the conclusions that can be drawn. Debate exists in the literature as to whether treated pyelonephritis is associated with adverse fetal outcomes. There is no clear consensus in the literature on antibiotic choice or duration of therapy for infection. With increasing antibiotic resistance, consideration of local resistance rates is necessary when choosing therapy.

Screening for asymptomatic bacteriuria is a standard of obstetrical care and is included in most antenatal guidelines. There is good evidence that treatment of asymptomatic bacteriuria will decrease the incidence of pyelonephritis. All pregnant women should be screened for asymptomatic bacteriuria, and there are no new data that would indicate otherwise. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of preterm delivery or low birth weight, but the methodological quality of the studies means any conclusion about the strength of this association needs to be drawn cautiously. A better understanding of the mechanism by which treatment of asymptomatic bacteriuria could prevent preterm delivery is needed. While several rapid screening tests have been evaluated, none perform adequately to replace urine culture for detecting asymptomatic bacteriuria. Until there are data from well-designed trials that establish the optimal duration of therapy for asymptomatic bacteriuria, standard treatment courses are recommended.

Background: Asymptomatic bacteriuria occurs in 2% to 10% of pregnancies and, if not treated, up to 30% of mothers will develop acute pyelonephritis. Asymptomatic bacteriuria has been associated with low birthweight and preterm delivery., Objectives: To assess the effect of antibiotic treatment for asymptomatic bacteriuria on persistent bacteriuria during pregnancy, the development of pyelonephritis and the risk of low birthweight and preterm delivery., Search Strategy: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2007)., Selection Criteria: Randomized trials comparing antibiotic treatment with placebo or no treatment in pregnant women with asymptomatic bacteriuria found on antenatal screening., Data Collection and Analysis: We assessed trial quality., Main Results: Fourteen studies were included. Overall the study quality was poor. Antibiotic treatment compared to placebo or no treatment was effective in clearing asymptomatic bacteriuria (risk ratio (RR) 0.25, 95% confidence interval (CI) 0.14 to 0.48). The incidence of pyelonephritis was reduced (RR 0.23, 95% CI 0.13 to 0.41). Antibiotic treatment was also associated with a reduction in the incidence of low birthweight babies (RR 0.66, 95% CI 0.49 to 0.89) but a difference in preterm delivery was not seen., Authors' Conclusions: Antibiotic treatment is effective in reducing the risk of pyelonephritis in pregnancy. A reduction in low birthweight is consistent with current theories about the role of infection in adverse pregnancy outcomes, but this association should be interpreted with caution given the poor quality of the included studies.

Background: Up to 30% of mothers develop acute pyelonephritis if asymptomatic bacteriuria is untreated. Asymptomatic bacteriuria may have a role in preterm birth or it may be a marker for low socioeconomic status which is associated with low birth weight., Objectives: The objective of this review was to assess the effect of antibiotic treatment for asymptomatic bacteriuria on persistent bacteriuria during pregnancy, the risk of preterm delivery, and the development of pyelonephritis., Search Strategy: I searched the Cochrane Pregnancy and Childbirth Group trials register. Date of last search: December 2000., Selection Criteria: Randomised trials comparing antibiotic treatment with placebo or no treatment in pregnant women with asymptomatic bacteriuria found on antenatal screening., Data Collection and Analysis: Trial quality was assessed., Main Results: Fourteen studies were included. Overall the study quality was not strong. Antibiotic treatment compared to placebo or no treatment was effective in clearing asymptomatic bacteriuria (odds ratio 0.07, 95% confidence interval 0.05 to 0.10). The incidence of pyelonephritis was reduced (odds ratio 0.24, 95% confidence interval 0.19 to 0.32). Antibiotic treatment was also associated with a reduction in the incidence of preterm delivery or low birth weight babies (odds ratio 0.60, 95% confidence interval 0.45 to 0.80)., Reviewer's Conclusions: Antibiotic treatment is effective in reducing the risk of pyelonephritis in pregnancy. An apparent reduction in preterm delivery is consistent with current theories about the role of infection in preterm birth, but this association should be interpreted with caution.

Background: Group B streptococcal infection is common in pregnant women without causing harm. However it is also a significant cause of neonatal morbidity and mortality., Objectives: The objective of this review was to assess the effects of intrapartum administration of antibiotics to women on infant colonization with group B streptococcus, early onset neonatal group B streptococcus sepsis and neonatal death from infection., Search Strategy: The Cochrane Pregnancy and Childbirth Group trials register was searched., Selection Criteria: Controlled trials of pregnant women colonized with group B streptococcus comparing intrapartum antibiotic administration with no treatment, and providing data on infant colonization with group B streptococcus and/or neonatal infection., Data Collection and Analysis: Eligibility and trial quality assessment were done by one reviewer., Main Results: Five trials were included. Overall quality was poor, with potential selection bias in all the identified studies. Intrapartum antibiotic treatment reduced the rate of infant colonization (odds ratio 0.10, 95% confidence interval 0.07 to 0.14) and early onset neonatal infection with group B streptococcus (odds ratio 0.17, 95% confidence interval 0.07 to 0. 39). A difference in neonatal mortality was not seen (odds ratio 0. 12, 95% confidence interval 0.01 to 2.00)., Reviewer's Conclusions: Intrapartum antibiotic treatment of women colonized with group B streptococcus appears to reduce neonatal infection. Effective strategies to detect maternal colonization with group B streptococcus and better data on maternal risk factors for neonatal group B streptococcus infection in different populations are required.
