title: N-Acetyl-β-D-hexosaminidase in gestational diabetes mellitus - a preliminary study.
abstract: OBJECTIVE
  N-Acetyl-β-D-hexosaminidase (HEX) is an exoglycosidase which has been extensively studied and which has been used as a marker for inflammation. It was therefore thought that measurement of the activity of this enzyme might be useful in diagnosing gestational diabetes mellitus (GDM) as this condition is frequently associated with inflammation. The main object of the study was the determination of N-acetyl-β-D-hexosaminidase activity in women with GDM and 3 months postpartum in comparison with control groups of non-pregnant and healthy pregnant women.
  
  
  METHODS
  Twenty-five blood serum samples from women with GDM and women 3 months postpartum; 20 blood serum samples from non-pregnant and healthy pregnant women (control groups) were enrolled into the study. Serum was prepared from all blood samples and HEX activity was measured by the method of Chateriee et al. (modified by Zwierz et al).
  
  
  RESULTS
  A statistically significantly increase in the activity of HEX in the GDM blood serum was found as compared to the control groups (p<0.05). Further analysis showed a statistically significant decrease in the activity of HEX among postpartum women, but the level of enzyme activity was still above the normal control level in comparison to the control group of nonpregnant healthy women (p<0.05).
  
  
  CONCLUSIONS
  Changes in the activity of HEX appear to be involved in the pathogenesis of gestational diabetes mellitus. Determination of HEX activity may have prognostic significance as an early indicator of diabetes mellitus among GDM women in the future.
