Abstract:
BACKGROUNDExtra glucose load in peritoneal dialysis is an important cause of newly-occurred diabetic mellitus, which initiates insulin treatment in some of the dialytic patients. The purpose of this study was to discuss the influence of the peritoneal transfer status on fasting blood glucose in non-diabetic nephropathy patients who are on continuous ambulatory peritoneal dialysis (CAPD).
METHODSOne hundred and forty-five patients with total KT/V per week over 2.0 were recruited, including 60 males and 85 females. Fasting blood glucose (FBG), creatinine, blood urea nitrogen (BUN), blood albumin, blood lipid profile and blood C-reactive protein (CRP) were analyzed at the beginning of the peritoneal dialysis and after 12 months. A peritoneal equilibration test (PET) was carried out at the 3rd month of CAPD, and meantime residual renal function, peritoneal solute clearance rate, ultrafiltration volume and urine volume were also evaluated.
RESULTSTwenty-one cases were identified as a low transfer group (L), 32 cases as a low average transfer group (LA), 58 cases as a high average transfer group (HA) and 34 cases as a high transfer group (H). At the end of the 12th month, 83 cases had elevated FBG. Through stepwise multiple regression analysis we found the FBG level in these patients was positively related to glucose load and CRP, and negatively related to glucose absorption in the peritoneum (D/D(0)) and blood albumin (P < 0.05). Kaplan-Meier analysis during a 48-month follow-up found the morbidity of hyperglycemia to be 17/34 cases (50.1%) in the high transfer group, 20/58 cases (34.5%) in the high average transfer group, 11/32 cases (34.3%) in the low average transfer group, and 1/21 cases (5.4%) in the low transfer group.
CONCLUSIONSPatients with high peritoneal transfer capacity might have the highest morbidity from hyperglycemia among patients with these four different peritoneal transfer status. Glucose load, baseline CRP and FBG level before peritoneal dialysis, and D/D0 can efficiently predict hyperglycemia in CAPD patients.
