BACKGROUND In areas of endemic transmission, malaria in pregnancy is associated with severe maternal anaemia and low birthweight babies. The prevalence of infection is highest in primigravidae (PG), and hence control efforts are usually geared towards this high risk group. Using a sensitive measure of placental infection, we investigated the relationship(More)
Granulated lymphocytes with an unusual antigenic phenotype (CD56+ CD38+ CD2 +/- CD3- CD16-) form a substantial proportion of leukocytes in human endometrial stroma. The purpose of this study was to examine morphological and antigenic heterogeneity in endometrial granulated lymphocytes (eGL) in imprint preparations, paraffin-embedded sections and frozen(More)
BACKGROUND In areas of endemic transmission, malaria in pregnancy is associated with severe maternal anaemia and low-birthweight babies. We studied the efficacy of intermittent treatment doses of sulphadoxine-pyrimethamine in preventing malaria and severe anaemia in pregnancy in a double-blind placebo-controlled trial among primigravid women living in(More)
Leukocytes comprise approximately 30-40% of decidual stromal cells in early human pregnancy. The major leukocyte component is the uterine natural killer (uNK) cells. Despite over 20 years of research the functional role of these cells in situ remains unknown although they have been proposed to play roles in immunotolerance, regulation of trophoblast(More)
Apoptosis has been implicated in the pathogenesis of several diseases and is partly regulated by bcl-2, which blocks the apoptotic pathway and promotes cell survival. Apoptosis and bcl-2 expression were examined in paired eutopic and ectopic endometrium from women with endometriosis (n = 30 samples) or adenomyosis (n = 15 samples) and compared with control(More)
Thyroid hormones (THs) are essential for normal fetal development, with even mild perturbation in maternal thyroid status in early pregnancy being associated with neurodevelopmental delay in children. Transplacental transfer of maternal THs is critical, with increasing evidence suggesting a role for 3,3',5-tri-iodothyronine (T3) in development and function(More)
BACKGROUND Extravillous trophoblast cell (EVT) invasion of decidua and inner third of the myometrium is critical for a successful pregnancy. Many decidual factors are likely to play a role in regulating this process, including uterine natural killer (uNK) cell-derived cytokines. HYPOTHESES 1) uNK cells are a major source of IFN gamma (IFN-gamma) and 2)(More)
The aetiology of endometriosis, a common and disabling disorder, is presently unknown, although immune dysfunction could allow ectopic endometrial fragments to survive outside the uterine cavity. These studies investigate the relationship between leukocyte populations, steroid hormone receptor expression, proliferative activity, bcl-2 expression and(More)
T lymphocyte subpopulations were compared in normal first trimester human decidua and in decidua associated with spontaneous abortion. Cryostat sections were labelled using a panel of monoclonal antibodies specific for CD3, CD8, CD4 and for the alphabeta and gammadelta heterodimers of the T cell receptor using an avidin-biotin complex peroxidase method. All(More)
OBJECTIVE To compare and quantify leukocyte populations at the tubal implantation site, in the tubal mucosa away from the implantation site and in the intrauterine decidua in women who have had an ectopic tubal pregnancy with leukocyte populations in the decidualized endometrium in women who have had a normal intrauterine pregnancy.
