Prevalence of diabetes mellitus and impaired glucose tolerance in cystic fibrosis.
1990
The aim of this study was to evaluate the prevalence of impaired glucose tolerance or diabetes mellitus in 99 patients (53 M, 46 F; mean age 10.5 +/- 6.9 years), with cystic fibrosis. Glucose tolerance was evaluated in all patients without overt diabetes using the oral glucose tolerance test (OGTT). Six patients showed a pathological OGTT and 2 patients had insulin-requiring diabetes mellitus. The mean age of the patients with impaired glucose tolerance was significantly higher than that of the subjects with normal glucose metabolism (p less than 0.0001). Patients with overt diabetes mellitus were the oldest subjects in the study group.
Professional continuous glucose monitoring in subjects with type 1 diabetes: retrospective hypoglycemia detection.
2013
Background: An important task in diabetes management is detection of hypoglycemia. Professional continuous glucose monitoring (CGM), which produces a glucose reading every 5 min, is a powerful tool for retrospective identification of unrecognized hypoglycemia. Unfortunately, CGM devices tend to be inaccurate, especially in the hypoglycemic range, which limits their applicability for hypoglycemia detection. The objective of this study was to develop an automated pattern recognition algorithm to detect hypoglycemic events in retrospective, professional CGM. Method: Continuous glucose monitoring and plasma glucose (PG) readings were obtained from 17 data sets of 10 type 1 diabetes patients und…
Differences in pharmacokinetics and pharmacodynamics of insulin lispro and aspart in healthy volunteers.
2003
Pharmacokinetic and pharmacodynamic profiles of the rapid-acting insulin analogues lispro and aspart were compared in a randomized, double-blind crossover study of 20 fasting healthy men following a single subcutaneous injection. Either insulin lispro or aspart, 0.05 U/kg-body-weight, was injected subcutaneously and followed by determination of 5-h profiles of plasma glucose, serum C-peptide and insulin concentrations. Lowest glucose concentrations were observed after 50 min in the aspart group (3.2 +/- 0.1 mmol/l versus lispro 3.5 +/- 0.1 mmol/l; p = 0.026) and after 60 min in the lispro group (3.4 +/- 0.1 mmol/l). For blood glucose t min was 59.3 +/- 3.4 min in the aspart and 63.5 +/- 5.3…
Implication of lipids in macrosomia of diabetic pregnancy: can n-3 polyunsaturated fatty acids exert beneficial effects?
2003
Macrosomia or fetal obesity is a frequent complication of pregnancy in diabetes mellitus. Several alterations observed in carbohydrate and lipid metabolism in macrosomic infants of diabetic mothers are thought to be a consequence of maternal hyperglycaemia leading to fetal hyperinsulinaemia. Macrosomic infants of diabetic mothers are prone to the development of glucose intolerance, obesity and diabetes during childhood and adulthood. Furthermore, increasing evidence is accumulating regarding the importance of n-3 polyunsaturated fatty acids (PUFAs) in the reduction of plasma lipids and hyperglycaemia. In this review article, we shed light on the abnormalities in lipid metabolism in macrosom…
Classical cardiovascular risk factors according to fasting plasma glucose levels
2007
To compare the prevalence of classical cardiovascular risk factors (CVRF) and metabolic syndrome (MetS) in our population according to fasting plasma glucose levels (FPG).We have studied 344 subjects between 20-70 years of age, recruited in a Primary Care Clinic. Subjects were divided into four groups according to their fasting plasma glucose (FPG) values: normal plasma glucose (NG) when FPG5.6 mmol/L; FPG between 5.6 and 6.0 mmol/L (FPG1); FPG between 6.1-6.9 mmol/L (FPG2); and diabetes (DM) FPGor = 7 mmol/L or previous diagnosis of diabetes. Cardiovascular risk factors (hypertension, TC/HDL-C index and Apo B values), presence of the MetS and indirect measure of insulin resistance (HOMA) w…
Visceral adiposity index and DHEAS are useful markers of diabetes risk in women with polycystic ovary syndrome
2014
ObjectiveOn the basis of the known diabetes risk in polycystic ovary syndrome (PCOS), recent guidelines of the Endocrine Society recommend the use of an oral glucose tolerance test (OGTT) to screen for impaired glucose tolerance (IGT) and type 2 diabetes (T2DM) in all women with PCOS. However, given the high prevalence of PCOS, OGTT would have a high cost–benefit ratio. In this study, we identified, through a receiver operating characteristic analysis, simple predictive markers of the composite endpoint (impaired fasting glucose (IFG) or IGT or IFG+IGT or T2DM) in women with PCOS according to the Rotterdam criteria.DesignWe conducted a cross-sectional study of 241 women with PCOS in a unive…
Placental infiltration of inflammatory markers in gestational diabetic women.
2013
Gestational diabetes mellitus (GDM) is pathology of glucose intolerance during pregnancy. It is influenced by maternal hyperglycemia and insulinemia through placental circulation. The study was undertaken to investigate the implication of pro-inflammatory factors in the placenta of GDM women. Thirty GDM women have delivered macrosomic babies, and 30 healthy age-matched pregnant women have delivered non macrosomic babies, were recruited in the study. The mRNAs encoding for IL-6, TLR4, TGF-β, CD68, CD14, EMR-1, CCL2, TCR-α, T-bet, GATA-3, leptin and adiponectin were quantified in placental samples by using RT-qPCR. The mRNA expression of the pro-inflammatory factors, i.e., IL-6, TLR4 and TGF-…
Pharmacotherapy for gestational diabetes mellitus: still insulin, or what about sulfonylureas?
2018
Randomized trials have not focused on neonatal complications of glyburide for women with gestational diabetes.To compare oral glyburide vs subcutaneous insulin in prevention of perinatal complications in newborns of women with gestational diabetes.The Insulin Daonil trial (INDAO), a multicenter noninferiority randomized trial conducted between May 2012 and November 2016 (end of participant follow-up) in 13 tertiary care university hospitals in France including 914 women with singleton pregnancies and gestational diabetes diagnosed between 24 and 34 weeks of gestation.Women who required pharmacologic treatment after 10 days of dietary intervention were randomly assigned to receive glyburide …
Abnormal pentagastrin response in a patient with pseudohypoparathyroidism
2002
The case of a 25 year old female patient with pseudohypoparathyroidism type I (PHP) and hypercalcitoninaemia is reported. She was referred to our clinic because of recurrent hypocalcaemia associated with paraesthesias and muscle cramps. She had no signs of Albright hereditary osteodystrophy (AHO), a normal mental status and no family history of hypocalcaemia or any other endocrine disease. Considering the laboratory results with hypocalcaemia, hyperphosphataemia, normal vitamin D and normal creatinine with an extraordinary elevated PTH we diagnosed pseudohypoparathyroidism type I. She had delayed pubertal development with menarche in the age of 20 and hypothyroidism with an atrophic thyroid…
Cryopreservation and autotransplantation of human ovarian tissue prior to cytotoxic therapy – A technique in its infancy but already successful in fe…
2008
Increasing survival rates in young cancer patients, new reproductive techniques and the growing interest in quality of life after gonadotoxic cancer therapies have placed fertility preservation as an important issue to oncologists, fertility specialists and patients. Several techniques are now available for fertility preservation in these patients. A new promising method is cryopreservation and transplantation of ovarian cortex. Ovarian tissue can be extracted by laparoscopy without any significant delay of gonadotoxic therapy. The tissue can be cryopreserved by specialised centres of reproductive medicine and transplanted in case the women experience premature ovarian failure (POF). This r…
