Blood disorder has little impact on pregnancy
Women with hemoglobin SC disease, an inherited blood disorder, can expect relatively normal pregnancy outcomes, according to a report in BJOG: an International Journal of Obstetrics and Gynecology.
With hemoglobin SC disease, red blood cells assume odd shapes, resulting in their premature destruction and anemia. Hemoglobin SC disease is closely related to sickle cell disease but is usually milder. Both disorders primarily affect people of African descent.
The new finding runs counter to claims that pregnancy related-problems are more common with hemoglobin SC disease than with sickle cell disease, lead author Dr. Graham R. Serjeant, from the Sickle Cell Trust in Kingston, Jamaica, and colleagues note.
In the current study, 95 pregnancies in 43 hemoglobin SC disease patients were compared with 94 pregnancies in 52 sickle cell disease patients and 157 pregnancies in 68 healthy comparison subjects.
All of the subjects had been followed from birth to assess the age at which menstruation began. Despite having a delay in menstruation of nearly 1 year relative to healthy subjects, patients with hemoglobin SC disease had a similar age at first pregnancy.
