Research Could Help Women Facing High Risk -- MEDICA Trade Fair

The research by Dr Harpal Randeva, Dr Paul O'Hare, Dr Dimitris Grammatopoulos; Consultant Endocrinologists and Mr Manu Vatish, Consultant Obstetrician, focussed on the profound alterations in the hormonal metabolism of pregnant women and the metabolic signals between mother and foetus. They particularly looked at a key signalling molecule, mainly produced by fat cells, called adiponectin. This is known to have anti-diabetic properties as well as anti-inflammatory and anti-atherogenic actions. They also closely examined levels of leptin which plays an important role in regulating energy balance and rises during pregnancy.

Given the high perinatal mortality associated with Type 1 diabetes, the researchers investigated adiponectin and leptin levels during both normal and Type 1 diabetic pregnancies. They measured both groups at 20 and 30 weeks into the pregnancy, and after giving birth.

Their novel observations showed that adiponectin levels were higher in pregnant women with type 1 diabetes at all stages of the study compared with the non-diabetic patients. Leptin levels were not different. Furthermore, they have identified adiponectin receptors on the human placenta and detected that the placenta also produces adiponectin. The researchers believe that the fetus produces adiponectin to protect itself from an adverse environment.

This is of vital importance since altered adiponectin levels could now be used to help give effective and early monitoring of the risks faced by women with type 1 diabetes and identify babies who are at risk. The researchers are now looking for support to extend their studies to develop biological markers for at risk pregnancies. They particularly wish to extend their studies to examine pregnant women with type 2 diabetes.; Source: University of Warwick
