Butyrylcholinesterase activity in gestational diabetes: correlation with lymphocyte subpopulations in peripheral blood.


Journal Article

PROBLEM: Inefficient clearance of pregnancy-threatening toxins may contribute to gestational diabetes (GD) and Type II diabetes mellitus (DM) through mechanisms involving immune dysregulation. METHOD OF STUDY: Peripheral venous blood from pregnant Kuwaiti women in third trimester, including 15 GD and 17 DM patients, 14 healthy pregnant (HP) and eight non-pregnant subjects, was analyzed by two-color flow cytometery for number and percentage representation of T lymphocytes. Buterylcholinesterase (BuChE) activity was measured using buterylthiocholine iodide and spectrophotometry. RESULTS: Relative to HP, GD patients exhibited higher ratios of activated and memory phenotypes, including CD4+ CD25+ (P < 0.01), CD4+ HLA-DR (P < 0.05) and CD4+ CD45RO+ (P < 0.05) cells. Serum BuChE activity exhibited positive correlation within the HP cohort with CD4+ CD25+ (P < 0.05), but not in GD and DM cohorts. CONCLUSIONS: Positive correlation between BuChE and a (presumptive) 'regulatory' T-cell phenotype in HP, but not GD or DM may indicate existence of protective detoxification mechanisms against oxidative stress in normal pregnancies.
