If so, expression should be increased in fetal anemia, especially when severe enough to cause hydrops fetalis. This has not been previously reported and the current study tested this hypothesis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>The study group consisted of 10 cases of anemic hydrops in second to early third trimester of gestation and 10 controls matched for gestational age. The majority (70%) of hydrops cases were due to hemoglobin (Hb) Bart. Placentas underwent CD15 immunohistochemical staining and results were quantitatively assessed by counting 100 vessels in each case.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      For the anemic group, the mean number of CD15+ vessels was 52.0% in the proximal vasculature and 91.3% in the distal vasculature. Values for controls were 32.9% and 42.2%, respectively. The CD15 expression in the distal vasculature was significantly higher in the anemic hydrops group (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001), but not significantly higher for the proximal vasculature (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.14). In the control group, the number of CD15+ vessels decreased with increasing gestational age for both proximal and distal vasculatures. In contrast, in the anemic hydrops group, the number of CD15+vessels did not significantly change with gestational age, for both the proximal and distal vasculatures.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Placentas belonging to anemic hydrops cases demonstrate significantly increased expression of CD15 in the distal vasculature.
