5%vs. 70.5%; P=0.02). Only 10 women (4.9%) had HIV RNA levels above 1000 copies/mL. Mean viral loads were not affected by the timing of ART initiation (Fig. 2). Figure 3 illustrates the trends in mode of delivery among HIV-infected women this website in Denmark between 1994 and 2008 according to treatment modalities in the parturient women. During the period 1994–1999, 84% of deliveries were by Caesarean section. During 2000–2004, only 7% of the women planned to deliver vaginally, this number rising to 31% in 2005–2006 and 46% in 2007–2008. Approximately one-third of the women delivered vaginally in 2007 and 2008. Eighty-six per cent of the women

delivering vaginally had undetectable HIV RNA and only one woman had high RNA levels (10,100 copies/mL). From 2005 an increase in acute Caesarean sections was seen. Of 47 women who planned to deliver vaginally, nine (19.1%) ended up with an acute Caesarean Buparlisib solubility dmso section and 33 of 150 women (22.0%) who planned to deliver by elective Caesarean section had an acute

Caesarean section performed. Table 1 shows the mode of delivery in each treatment group. Obstetrical complications were recorded for 13 of 224 deliveries (5.8%), including five cases of pre-eclampsia (all 13 mothers were on ART), and postpartum complications occurred in six women delivering by Caesarean section (excessive bleeding, wound abscess, uterus atonia, cicatricial infection and fasciae rupture). As shown in Table 2, the median gestational age was 38 weeks (range 25–42 weeks); 32 of 188 deliveries (17.0%) were premature (<37 weeks), and eight of 188 (4.3%) were very premature (<32 weeks). The median birth weight was 3050 g (range 849–4520 g); 31 of 231 infants (13.4%) had low birth weight (<2500 g), and six of 231 (2.6%) had very low birth weight (<1500 g). Apgar scores at 1 and 5 min were 8 or more for 190 of 208 children (91.3%) and 207 of 210 children (98.6%), respectively. Physical examination at birth was normal for 180 of 216 children (83.3%).

Abnormalities included dysmaturity, abstinences, congenital heart defects, respiratory distress, mafosfamide limb anomalies, hydroceles, and cleft lip and palate. A quarter of the children were defined as anaemic at birth (Hgb <8.7 mmol/L). No significant differences in the characteristics of the children were observed between the maternal treatment groups. Two hundred and forty-four children (95.3%) received postpartum ZDV for 4 or 6 weeks, four children were treated with post-exposure prophylaxis (PEP) because of late diagnosis, one was treated because of maternal refusal of antenatal prophylaxis, and one because of an accidental cut in the scalp. Six children born before the year 2000 did not receive postpartum prophylaxis, and for two children information on ZDV prophylaxis was not available. Vertical transmission of HIV occurred in six children, giving an overall MTCT rate of 2.4%. Five of the infected children were born in 1994–1999, giving an MTCT rate of 10.4% declining to 0.
