Throughout study participation and pregnancy this participant had an undetectable viral load; a CD4 count that ranged from 845–861 cells/mm3; no evidence of anemia; no pre-eclampsia (blood pressure consistently under 130/90), no proteinuria or glycosuria; no significant weight loss; took iron and folic acid supplementation; no trauma; normal fetal growth as measured by fundal height; no per vaginal bleeding or ulcers; no signs or symptoms of sexually transmitted infections and tested negative for syphilis; normal fetal heart rate; and attended ANC visits as recommended.
