Spontaneous abortion among insulin-dependent diabetic women
Abstract:
A prospective study was undertaken to evaluate the frequency of spontaneous abortion in clinically apparent pregnancies among insulin-dependent diabetic women evaluated prior to pregnancy. The study was done in 132 pregnancies occurring in 91 diabetic women. The spontaneous abortion rate was 30%; 70% of the pregnancies progressed beyond 20 weeks. The abortion rates for Classes B, C, D, and F through RT were 0%, 25%, 44%, and 22%, respectively. Initial serum levels of the beta-subunit of human chorionic gonadotropin above 6000 mIU were usually associated with favorable outcome while levels below 6000 mIU were not predictive of outcome. Data from this study suggest that the risk of spontaneous abortion among insulin-dependent diabetic women may be substantially higher than for the general population. Higher abortion rates were generally associated with more advanced White classification of diabetes. Age at diagnosis was the only factor which showed a significant contribution to the risk of abortion.

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
