Filter by:Objectives: This study is aimed to assess whether Tianqi Capsule interventions have a long-term effect on the risk of diabetes and provide evidence that early intervention by traditional Chinese medicine could delay the progression from impaired glucose tolerance to diabetes. Study contents: 1.420 participants were followed up for 8 years to assess the long-term effect of Tianqi Capsule. Phone-call followed up was applied to investigate the status of impaired glucose tolerance and orthoglycemic survivors until the end of REDUCES study. 2.To participants that determined the status of glucose metabolism, a variety of ways were used to find the evidence of diagnosis of glucose metabolic status, such as glycemia laboratory sheets from normal hospitals, medical records, the use of antidiabetic drugs or insulin injection, etc. 3. To participants that undiagnosed the status of glucose metabolism, oral glucose tolerance test, blood pressure, weight and blood biochemical analysis were performed to assess the state of glucose metabolism. 4. Questionnaires were given to all the participants to investigate their condition of treatment, diet, exercise and other lifestyle.
The prevalence of type 2 diabetes has consistently increased and type 2 diabetes can cause many types of vascular complications. Diabetes develops due to glucose intolerance. Early detection and intervention in the stage of glucose intolerance makes it afford to prevent overt diabetes and its complications. This study was designed to make a cohort of korean patients with glucose intolerance to construct a long term database about clinical characteristics of these patients.
The purpose of this observational study is to assess the treatment and outcomes of patients with prediabetes in community-based clinical practices.
This study will evaluate the feasibility and efficacy of two interventions of lifestyle ( intensive and less intensive) to prevent diabetes in patients from Ethiopian origin, aged 25 to 55 years old with prediabetes living in Israel and insured by Clalit Health Services in the Central district, using resources existing in this Health Care system (HMO).
Introduction: The overall aim of the study is to assess the efficacy of Lactobacillus Rhamnosus in reducing glucose intolerance during and after pregnancy. A second objective of the study is to determine the feasibility, compliance and safety of Lactobacillus Rhamnosus among this cohort. Within this goal is to determine whether the investigators can enroll women at high risk for developing Gestational Diabetes Mellitus (GDM) and follow them out at regular antenatal visits and 6-weeks post partum. Women with GDM are, 7 times more at risk of developing type 2 diabetes compared with those who had a normo- glycaemic pregnancy. The population attributable risk for type 2 diabetes mellitus (DM) in women with GDM is high, and around 30 - 50% women with GDM converts into type 2 (DM) which is associated with pre-mature morbidity, mortality and high economic burden. It is evident that untreated GDM is associated with higher incidence of complications during pregnancy and increases the risk of perinatal mortality and infant morbidity. The prevalence of GDM in Pakistan is around 8%, comparatively higher than other South Asian countries. Therefore, interventions that can improve glucose regulation during pregnancy are highly important. Probiotics, the live micro-organisms, have shown promising results in regulating glucose metabolism among pregnant mice. The effect of Probiotics on glucose metabolism is attributable to their immuno-regulatory properties. They elicit powerful anti-inflammatory capabilities by inhibiting the NF-kB pathway, which mediates microbial activation of the immune system. Further, they diminish both fermentation of polysaccharides and induction of fasting-induced adipocyte factor gene transcription. The safety of Lactobacillus Rhamnosus among pregnant women is already established in other diseases. A placebo controlled trial from Finland on pregnant females randomized to receive either dietary counseling and Probiotics (Lactobacillus Rhamnosus), concluded improved glucose tolerance as compared to the placebo group [OR 0.31 (95% CI 0.12, 0.78)]. However, this study could not determine the sole effects of probiotics in reducing glucose intolerance. Nevertheless, no studies on the role of Lactobacillus Rhamnosus in regulating glucose intolerance have been conducted in any other part of the world yet. Therefore, a pilot trial to see the efficacy, compliance and feasibility of Lactobacillus Rhamnosus among pregnant females is imperative. The objectives of the investigators study are: - To assess the efficacy of Probiotics Lactobacillus Rhamnosus (1010 Colony forming Units (CFU)/day) in reducing glucose intolerance among pregnant women attending antenatal clinic of Karachi-Pakistan. - To assess the feasibility, compliance and safety of conducting a double blind, placebo controlled randomized trial of Lactobacillus Rhamnosus by recruiting high risk women during pregnancy attending antenatal clinics and following them up 6 weeks postpartum in Karachi-Pakistan. Methods: For the pilot trial, women will be recruited from antenatal hospital of the city, during 12-14 weeks of gestation. Study Design: The study will be double blind randomized, placebo controlled trial. Randomization will be done by blocked method. The dose of 1010 Colony forming Units (CFU) once daily till delivery will be given orally. Study Endpoints and Ascertainment: Baseline information will be comprised of socioeconomic status, parity, gravida, blood pressure and obstetric history etc. The study endpoint comprises of efficacy, feasibility, compliance and safety and will be ascertained at monthly follow-up, during week 24 - 28, and 6 weeks post partum. Efficacy will be ascertained by Oral Glucose Tolerance Test (OGTT) performed at randomization and during 24-28 weeks of gestation. Feasibility and compliance will be assessed through recruitment rate, drop-out rate, reasons for drop-out, non-participation and empty drug sachet count.
High risk population: Screening for impaired glucose tolerance.
The purpose of this study is to determine whether treating pre-diabetic & pre-hypertensive individuals using multiple drugs intervention (anti-hypertensive drugs (i.e., ACEI) plus anti-glycemic drug (i.e., metformin) plus anti-hyperlipidemic drug (statin)) would lower Cardiovascular Disease (CVD) events.
The purpose of the study is to evaluate whether insulin treatment during pulmonary exacerbation (PE) in patients with Cystic Fibrosis (CF)and normoglycemia improves their short term outcome by normalizing the glycemic profile and enhancing recovery. the investigators would like to evaluate whether insulin treatment during exacerbation improves both the general clinical condition of these patients and also has a protecting effect on ß-cells by preventing the deleterious effect of "chronic" hyperglycemia.
The prevalence of type 2 diabetes is rising in the population for many years. It is now recognized that a period of glucose intolerance precedes the clinical symptoms appearance. This is due to a combination of b-cell dysfunction and insulin resistance. It is estimated that this pre-clinical phase of type 2diabetes may antedate the onset of overt diabetes by 10-12 years. Furthermore, insulin resistance is considered to be a main component of the metabolic syndrome and associated with significant cardiovascular morbidity and mortality. Recently, there has been an effort to pinpoint the pre-diabetic phase for early therapeutic intervention in the individual. These studies, in patients with impaired glucose intolerance, have shown to be beneficial from both lifestyle change and pharmacological intervention. It is thus hypnotized that intervention in patients with insulin resistance with or without glucose intolerance may prevent the progress of type 2 diabetes and it’s complications. There is difficulty in identifying individuals who are at high risk for type 2 diabetes. The prevention strategy relies on intervention in a pre-diseased state. In the case of type 2 diabetes, the early intervention is useful in the phase where there is insulin resistance, but prior to the appearance of glucose intolerance. The diagnosis of insulin resistance is a challenging one. The gold standard in diagnosing insulin resistance is the hyperinsulinemic-euglycemic clamp, but this method is not suitable for routine clinical use. Thus, less invasive methods for evaluation, like homeostasis model assessment (HOMA) and quantitative insulin sensitivity check index (QUICKI), were developed. There is a correlation between HOMA and QUICKI results and the hyperinsulinemic-euglycemic clamp. Both HOMA and QUICKI allow insulin resistance diagnosis. The results from those tests correlate with hyperinsulinemic-euglycemic clamp and allow diagnosing insulin resistance, however, those indexes require serum glucose, insulin measurements and quite complicated calculations. A new method was suggested, non-invasive, sensitive and simple, for the identification of insulin resistance. In normal individuals, in the presence of insulin, glucose is taken up by a variety of cells, undergoes glycolysis and enters the tricarboxylic acid cycle or fat synthesis. In either case, CO2 in produced as a by-product. This CO2 enters the circulation and is discarded by the lungs. The new method is based on the assumption that 13C-glucose is ingested as described and its by-product 13CO2 can be measured in the expired air. In type 2 diabetes and other states of insulin resistance glucose, uptake is impaired and results in blunted 13CO2 production. This hypothesis was tested by Lewanczuc et al. The writers compared the [13C]-glucose breath test with hyperinsulinemic-euglycemic clamp, HOMA and QUICKI indexes. They tested 26 patients at different stages of insulin sensitivity and reported a good correlation of the glucose breath test and the other indexes. We suggest testing a larger group of patients at high-risk to develop type 2 diabetes and compare the glucose breath test with HOMA index.
