Therefore, we assessed the impact of long acting Octreotide (Sandostatin LAR) monthly Intramuscular administration in a subject with Type 1 DM. Methods: A 32-year-old man with Type 1 DM of 16 years participated after obtaining informed consent. He had no microvascular or macrovascular complications. He continued the present insulin regimen for four weeks. IM Sandostatin LAR 20 mg was initiated and increased at four weeks to 30 mg. He was followed every four weeks for six months. Insulin regimen was adjusted every two weeks based on blood glucose before meals, bedtime and on onset of hypoglycemic symptoms. He continued other medications, previous diet and activity Assessment of HbA1c, serum electrolytes, urea nitrogen, creatinine, TSH, free T4, liver enzymes, complete blood cell counts, vitamin B12, lipids and insulin regimen were performed at the initiation and end of the study. Results: HbA1c declined from 9 to 8% with reduction in daily insulin dose from 55 to 43 units, with a major reduction in insulin Glargine, 50 to 40 units. Body weight remained unaltered. Other laboratory tests including gallbladder examina-tion remained unchanged Conclusion: Monthly Sandostatin LAR administration may improve glycemic control with less insulin in Type 1 DM.展开更多

It most commonly occurs secondary to a precipitating event such as an infection, non-infectious illness, or insulin non-compliance. We report a case of a 28-year-old male with a history of well-controlled type 1 diabetes mellitus who began having frequent and repeated episodes of DKA. Evaluation for compliance lapses was negative. The further review noted a worsening white blood cell count over the same period, despite repeated negative infectious workups. A bone marrow biopsy revealed a hypercellular marrow with granulocyte and megakaryocyte proliferation. Testing for the BCR-ABL fusion gene was positive in 92% of cells. This led to a final diagnosis of chronic myeloid leukemia as the precipitator for repeated presentation with DKA. The two diseases do not commonly present simultaneously due to differences in median age. No previous reports of adults with DKA precipitated by CML are present in the literature. However, worsening hyperglycemia has been reported with other hematologic malignancies, particularly in the setting of acute lymphoblastic leukemia in the pediatric population. This is thought in some instances to be due to the leukemic process itself, potentially through cytokine release.展开更多

The effect of adipokines such as leptin, resistin and adiponectin which are secreted by adipose tissue factors has been linked to the increased risk of the cardiovascular mortality and morbidity. Aim: This study aims to assess the levels of serum leptin and serum adiponectin in obese type 2 diabetes subjects, and their relationship with cardio-metabolic component (using lipid profile). Method: This is a cross-sectional comparative hospital-based study in which one hundred and fifty participants grouped into 60 obese, 60 non-obese none diabetic and 30 non-obese non-diabetic adults with similar age from the Endocrinology outpatient’s clinic, General outpatient department (GOPD) and staff clinic of Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC). Anthropometric parameters and other relevant clinical details of all subjects were obtained. Fasting venous blood samples were taken from all subjects for the determination of fasting plasma glucose (FPG), fasting lipid profile, glycosylated haemoglobin levels (HbA<sub>1C</sub>), fasting serum insulin, leptin, and adiponectin. Data was analysed using the Statistical Package of Social Sciences (SPSS) version 23.0. Results: Twenty-eight (46.7%)) subjects were males while 32 subjects (53.3%) were females (in obese groups). There was no statistical difference between these two groups for both sexes (p = 1.000). The age range for all subjects was 34 to 64 years with their mean age being 52 ± 7.3 years, and for type 2 subjects and the obese non-diabetic 50.7 ± 7.3 years respectively. The mean body mass index of the non-obese and non-diabetic was 23.7 ± 4 Kg/m<sup>2</sup> while the anthropometric measurements of the obese two groups were similar. The lipid profile, serum leptin and adiponectin in both the obese groups showed no difference. The relationship between components of obesity and serum leptin level in all subjects showed that serum leptin levels had significant positive correlation with BMI, WC, and serum insulin level. The correlation between adiponectin and lipid profile showed a positive correlation between serum adiponectin values and High-density lipoprotein (HDL) in obese diabetic (p = 0.02) but not in the non-diabetic group. Conclusion: In this study, there was no correlation in the serum leptin levels with the anthropometric parameters of obesity studied. For the components of the lipid profile, Triglycerides and low-density lipoprotein cholesterol (LDL) correlated with serum adiponectin and HDL showed a positive correlation with adiponectin. It is concluded that the effects of both serum adiponectin and serum leptin are driven by obesity rather than the glycaemic status of the obese subjects.展开更多

With Type 2 DM, the more common type, the body does not make or use insulin well. In patients with DM, Helicobacter pylori is one of the most common infections worldwide. Available data on the possible association between H. pylori infection and DM are contradictory. There are a few studies in the Middle East, and this study is the pioneer study, in the Medical Services Clinics in Gaza strip. Aims: This study was conducted to reveal the prevalence of H. pylori infection, malnutrition, insulin resistance among T2DM patients, to describe the dietary requirements of T2DM patients, finally to evaluate the current information about diet, and lifestyle in the prevention of H. pylori, and malnutrition. Methodology: A cross-sectional study was conducted in the Medical Services Clinics in Gaza Strip, and there were 129 patients included in this study. Data were collected through hematological information and structured interview questionnaire. Results: Highly significant percentage of H. pylori (70%) among the DM patients includes in the study, but not indicates any significant association between gender and H. pylori status. Conclusion: H. pylori patients should update their sugar level values in the record, and should get exercise and diet plan for every meal.展开更多

Inhibition of hSGLT2 has been regarded as a brand new therapeutic approach for the treatment of type 2 diabetes mellitus (T2DM) due to its non-insulin related characteristics with less side effects. Current commercially available hSGLT2 inhibitors are all C-glycoside inhibitors. Previous studies have reported that N-glycoside inhibitors have better potential to serve as new drugs due to their good metabolic stability. In addition, non-glycoside inhibitors have been shown to exhibit the capability to overcome the existing problems of current glycoside inhibitors, including low tissue permeability, poor stability and short serum half-time. Here, we aimed to discover novel N-glycoside and non-glycoside hSGLT2 inhibitors by a combination of several computational approaches. A ligand-based pharmacophore model was generated, well validated and subsequently utilized as a 3D query to identify novel hSGLT2 inhibitors from National Cancer Institute (NCI) and Traditional Chinese Medicine (TCM) databases. Finally, one N-glycoside (NSC679207) and one non-glycoside (TCM_Piperenol_A) hSGLT2 inhibitors were successfully identified, which were proven to exhibit excellent binding affinities, pharmacokinetic properties and less toxicity than the commercially available hSGLT2 inhibitor, canagliflozin, via molecular docking, ADMET prediction, molecular dynamics (MD) simulations and binding free energy calculations. All together, our results strongly suggest that these two compounds have great potential to serve as novel hSGLT2 inhibitors for the treatment of T2DM and their efficacies may be further examined by a series of in vitro and/or in vivo bioassays.展开更多

A prospective study including 256 type II diabetic patients who referred to diabetes’s clinic was designed. All patients underwent physical & retina examination and then completed questionnaire including duration of DM, cardiovascular disease, stroke, chronic kidney disease, smoking, and kind of treatment, blood pressure, BMI, abdominal & hip circumference. Results of HbA1C, total cholesterol, HDL & LDL cholesterol, TG, FBS, creatinine, 24-h urine microalbumin were recorded. Data were analyzed by SPSS version 17 with K2, independent samples T, and logistic regression. Of 256 types II diabetic patients 81 & 175 were men and women respectively. Mean age of subject was 54 ± 10.27. Prevalence of diabetic retinopathy was 22.3% & macula edema 0.5% & PDR 6% & NPDR 14%;diabetic retinopathy was associated with duration of DM & BMI (P = 0, P = 0.43 respectively). Mean of FBS 191 ± 83 vs. 165.7 ± 74.5 (P = 0.03), HbA1c 9.1 ± 2 vs. 8.5 ± 1.9 (P = 0.02), 24-h urine microalbumin 181.2 ± 404.7 vs. 60.2 ± 236 (P = 0.03), Systolic blood pressure 124.3 ± 21.3 vs. 118.5 ± 17.8 (p = 0.04) differed between diabetic patients with or without diabetic retinopathy. There were no significant difference between subject with & without diabetic retinopathy in total cholesterol LDL, HDL, TG, Cr, Diastolic BP, types of treatment, cardiovascular disease, chronic kidney disease, stroke & smoking. This study showed prevalence of diabetic retinopathy was high and it associated with duration of DM, BMI, FBS, HbA1C, 24-h urine albumin, and systolic blood pressure.展开更多

文摘Diabetic ketoacidosis (DKA) is a life-threatening complication of diabetes characterized by metabolic acidosis, hyperglycemia, and ketosis. It most commonly occurs secondary to a precipitating event such as an infection, non-infectious illness, or insulin non-compliance. We report a case of a 28-year-old male with a history of well-controlled type 1 diabetes mellitus who began having frequent and repeated episodes of DKA. Evaluation for compliance lapses was negative. The further review noted a worsening white blood cell count over the same period, despite repeated negative infectious workups. A bone marrow biopsy revealed a hypercellular marrow with granulocyte and megakaryocyte proliferation. Testing for the BCR-ABL fusion gene was positive in 92% of cells. This led to a final diagnosis of chronic myeloid leukemia as the precipitator for repeated presentation with DKA. The two diseases do not commonly present simultaneously due to differences in median age. No previous reports of adults with DKA precipitated by CML are present in the literature. However, worsening hyperglycemia has been reported with other hematologic malignancies, particularly in the setting of acute lymphoblastic leukemia in the pediatric population. This is thought in some instances to be due to the leukemic process itself, potentially through cytokine release.

文摘Type 2 diabetes mellitus(T2DM)is associated with liver dysfunction and intestinal dysbiosis.Bioactive peptides(BAPs)have been reported to ameliorate T2DM by preventing oxidative damage to the liver.Bacillus amyloliquefaciens fmb50 produces the lipopeptide surfactin with a wide range of biological activities.The effects of surfactin on T2DM,on the other hand,have not been studied.In the present study,80 mg/kg body weight surfactin supplementation lowered fasting blood glucose(FBG)levels by 21.05%and insulin resistance(IR)by 18.18%compared with those in the T2DM group,reduced inflammation,and increased antioxidant activity in mice with T2DM induced by a high-fat diet(HFD)and streptozotocin(STZ).According to further research,surfactin administration reduced Firmicutes-to-Bacteroidetes ratios while increasing Bifi dobacterium abundance by 20 times and the level of the tight junction protein Occludin by 18.38%and ZO-1 by 66.60%.Furthermore,surfactin also improved hepatic glucose metabolism by activating the adenosine monophosphate-activated protein kinase(AMPK)signalling pathway,increasing glycogen synthesis and glucose transporter 2(GLUT2)protein expression while reducing glucose-6-phosphatase(G6Pase)protein expression.In addition,the increased Bifi dobacterium abundance indirectly reduced the liver burden of the metabolic products indole,cresol and amine produced by saprophytic bacteria.All of these findings revealed that surfactin not only ameliorated HFD/STZ-induced gut dysbiosis and preserved intestinal barrier integrity but also enhanced hepatic glucose metabolism and detoxifi cation function in T2DM mice.The gut microbiota appeared to be important in controlling glucose metabolism,IR,fat accumulation,inflammation and antioxidation,according to Spearman’s correlation coeffi cients.All data indicated that surfactin alleviated hyperglycaemia in mice with T2DM induced by HFD/STZ.
文摘Background: Obesity is rising globally, independent of ethnicity, race and age, and is associated with increased risk of cardiovascular mortality and morbidity especially in persons living with diabetes. The effect of adipokines such as leptin, resistin and adiponectin which are secreted by adipose tissue factors has been linked to the increased risk of the cardiovascular mortality and morbidity. Aim: This study aims to assess the levels of serum leptin and serum adiponectin in obese type 2 diabetes subjects, and their relationship with cardio-metabolic component (using lipid profile). Method: This is a cross-sectional comparative hospital-based study in which one hundred and fifty participants grouped into 60 obese, 60 non-obese none diabetic and 30 non-obese non-diabetic adults with similar age from the Endocrinology outpatient’s clinic, General outpatient department (GOPD) and staff clinic of Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC). Anthropometric parameters and other relevant clinical details of all subjects were obtained. Fasting venous blood samples were taken from all subjects for the determination of fasting plasma glucose (FPG), fasting lipid profile, glycosylated haemoglobin levels (HbA<sub>1C</sub>), fasting serum insulin, leptin, and adiponectin. Data was analysed using the Statistical Package of Social Sciences (SPSS) version 23.0. Results: Twenty-eight (46.7%)) subjects were males while 32 subjects (53.3%) were females (in obese groups). There was no statistical difference between these two groups for both sexes (p = 1.000). The age range for all subjects was 34 to 64 years with their mean age being 52 ± 7.3 years, and for type 2 subjects and the obese non-diabetic 50.7 ± 7.3 years respectively. The mean body mass index of the non-obese and non-diabetic was 23.7 ± 4 Kg/m<sup>2</sup> while the anthropometric measurements of the obese two groups were similar. The lipid profile, serum leptin and adiponectin in both the obese groups showed no difference. The relationship between components of obesity and serum leptin level in all subjects showed that serum leptin levels had significant positive correlation with BMI, WC, and serum insulin level. The correlation between adiponectin and lipid profile showed a positive correlation between serum adiponectin values and High-density lipoprotein (HDL) in obese diabetic (p = 0.02) but not in the non-diabetic group. Conclusion: In this study, there was no correlation in the serum leptin levels with the anthropometric parameters of obesity studied. For the components of the lipid profile, Triglycerides and low-density lipoprotein cholesterol (LDL) correlated with serum adiponectin and HDL showed a positive correlation with adiponectin. It is concluded that the effects of both serum adiponectin and serum leptin are driven by obesity rather than the glycaemic status of the obese subjects.
文摘With lifestyle changes,the incidence of type 2 diabetes(T2DM)and obesity has significantly increased,becoming major chronic diseases that seriously threaten the health of China’s residents.Both domestic and international guidelines and consensus exist regarding the diagnosis and management of this disease.In recent years,T2DM treatment has focused more on new tactics that lean towards a patient-centered comprehensive management approach,replacing the traditional glucose-centered approach.Additionally,an increasing amount of evidence in medicine suggests that the reversal of diabetes is possible.However,there is currently no expert consensus on the clinical management of T2DM combined with obesity reversal treatment.Therefore,experts and scholars in China with extensive experience in T2DM combined with obesity reversal treatment have been invited to develop this consensus.The content includes early identification and diagnosis of T2DM combined with obesity,definition and mechanisms of diabetes reversal,disease assessment and grading,staging of diabetes and goals of reversal,the 2+N reversal strategy,inpatient system treatment combined with comprehensive outpatient management(including weight control,precise nutrition,scientific exercise,glucose-lowering medication,psychological intervention,rehabilitation therapy,and remote follow-up through online platforms),and evaluation of post-reversal efficacy.The aim is to further improve the level of T2DM combined with obesity reversal diagnosis,treatment,and management in China,and to implement the Healthy China strategy.

文摘Type 2 diabetes mellitus (T2DM) accounts for 90% of all diabetes cases and results in severe complications. It is a multifactorial metabolic disorder that results from a combination of resistance to insulin action and an inadequate compensatory insulin secretory response. The interaction between multiple genetic and environmental determinants has been considered to contribute to the pathogenesis of T2DM[1].
文摘Background: Diabetes means the blood glucose, which is too high or too low. With Type 2 DM, the more common type, the body does not make or use insulin well. In patients with DM, Helicobacter pylori is one of the most common infections worldwide. Available data on the possible association between H. pylori infection and DM are contradictory. There are a few studies in the Middle East, and this study is the pioneer study, in the Medical Services Clinics in Gaza strip. Aims: This study was conducted to reveal the prevalence of H. pylori infection, malnutrition, insulin resistance among T2DM patients, to describe the dietary requirements of T2DM patients, finally to evaluate the current information about diet, and lifestyle in the prevention of H. pylori, and malnutrition. Methodology: A cross-sectional study was conducted in the Medical Services Clinics in Gaza Strip, and there were 129 patients included in this study. Data were collected through hematological information and structured interview questionnaire. Results: Highly significant percentage of H. pylori (70%) among the DM patients includes in the study, but not indicates any significant association between gender and H. pylori status. Conclusion: H. pylori patients should update their sugar level values in the record, and should get exercise and diet plan for every meal.

文摘[ Objective] The research aimed to discuss the relationship between the polymorphism of PPARy.2 gene and the susceptibility of type 2 diabetes mellitus （T2DM） in Guangxi Bama mini-pigs. [ Method] 24 Guangxi Bama mini-pigs were fed with high-fat and high-sucrose diet, and partial sequences of exon 2 of PPARy-2 gene were amplified by using PCR method. In addition, the contents of fasting blood glucose and insulin （INS） in Guangxi Bama mini-pigs were determined, and the glucose tolerance test （GTT） was also carried out. [ Result] There was one SNP site （19813A/G） Jn partial sequence of exon 2 of the cloned PPAFly-2 gene, and AA （7 pigs） and AG （17 pigs） genotype were detected. The contents of fasting insulin and 60-min blood glucose in GTT in AG-genotype Guangxi Bama mini-pigs were significantly higher than those of AA genotype （ P 〈0.05）, while the incidence of T2DM in AG-genotype Guangxi Bama mini-pigs （71.4%） was obviously higher than that of AA gen- otype （5.9%）. [ Conclusion] The polymorphism of 19813A/G in exon 2 of PPARy-2 gene was related with the susceptibility of T2DM in Guangxi Bama mini-pigs.

文摘We observed the polymorphism distribution and coaction of uncoupling protein 3（UCP3）-55C/T,adiponectin（APN）＋45T/G and tumor necrosis factor（TNF）-α-308G/A on the onset and development of T2DM in a Northern Chinese Han population of 213[100 type 2 diabete（T2DM） patients and 113 health control subjects] by polymerase chain reaction-restriction fragment length polymorphisum（PCR-RFLP） method.Results demonstrate the polymorphism of UCP3-55C/T,APN＋45T/G,and TNF-α-308G/A related to T2DM onset and developement.And the individuals carrying UCP3-55T,APN＋45G and TNF-α-308A allele had higher T2DM risk.Those results are the first report to evaluate the association of the coaction of UCP3,APN,TNF-α genes polymorphism on T2DM risk and the susceptibility of T2DM in the Northern Chinese Han population.
文摘Human sodium-glucose cotransporter 2 (hSGLT2) is a membrane protein responsible for glucose reabsorption from the glomerular filtrate in the proximal tubule. Inhibition of hSGLT2 has been regarded as a brand new therapeutic approach for the treatment of type 2 diabetes mellitus (T2DM) due to its non-insulin related characteristics with less side effects. Current commercially available hSGLT2 inhibitors are all C-glycoside inhibitors. Previous studies have reported that N-glycoside inhibitors have better potential to serve as new drugs due to their good metabolic stability. In addition, non-glycoside inhibitors have been shown to exhibit the capability to overcome the existing problems of current glycoside inhibitors, including low tissue permeability, poor stability and short serum half-time. Here, we aimed to discover novel N-glycoside and non-glycoside hSGLT2 inhibitors by a combination of several computational approaches. A ligand-based pharmacophore model was generated, well validated and subsequently utilized as a 3D query to identify novel hSGLT2 inhibitors from National Cancer Institute (NCI) and Traditional Chinese Medicine (TCM) databases. Finally, one N-glycoside (NSC679207) and one non-glycoside (TCM_Piperenol_A) hSGLT2 inhibitors were successfully identified, which were proven to exhibit excellent binding affinities, pharmacokinetic properties and less toxicity than the commercially available hSGLT2 inhibitor, canagliflozin, via molecular docking, ADMET prediction, molecular dynamics (MD) simulations and binding free energy calculations. All together, our results strongly suggest that these two compounds have great potential to serve as novel hSGLT2 inhibitors for the treatment of T2DM and their efficacies may be further examined by a series of in vitro and/or in vivo bioassays.
文摘The aim of this study was to establish diabetic retinopathy correlation with several risk factors. A prospective study including 256 type II diabetic patients who referred to diabetes’s clinic was designed. All patients underwent physical & retina examination and then completed questionnaire including duration of DM, cardiovascular disease, stroke, chronic kidney disease, smoking, and kind of treatment, blood pressure, BMI, abdominal & hip circumference. Results of HbA1C, total cholesterol, HDL & LDL cholesterol, TG, FBS, creatinine, 24-h urine microalbumin were recorded. Data were analyzed by SPSS version 17 with K2, independent samples T, and logistic regression. Of 256 types II diabetic patients 81 & 175 were men and women respectively. Mean age of subject was 54 ± 10.27. Prevalence of diabetic retinopathy was 22.3% & macula edema 0.5% & PDR 6% & NPDR 14%;diabetic retinopathy was associated with duration of DM & BMI (P = 0, P = 0.43 respectively). Mean of FBS 191 ± 83 vs. 165.7 ± 74.5 (P = 0.03), HbA1c 9.1 ± 2 vs. 8.5 ± 1.9 (P = 0.02), 24-h urine microalbumin 181.2 ± 404.7 vs. 60.2 ± 236 (P = 0.03), Systolic blood pressure 124.3 ± 21.3 vs. 118.5 ± 17.8 (p = 0.04) differed between diabetic patients with or without diabetic retinopathy. There were no significant difference between subject with & without diabetic retinopathy in total cholesterol LDL, HDL, TG, Cr, Diastolic BP, types of treatment, cardiovascular disease, chronic kidney disease, stroke & smoking. This study showed prevalence of diabetic retinopathy was high and it associated with duration of DM, BMI, FBS, HbA1C, 24-h urine albumin, and systolic blood pressure.
