妊娠糖尿病患者血清HbA1c与CRP水平的相关性分析

目的:为明确妊娠期糖尿病(gestational diabetes mellitus,GDM)患者血清糖化血红蛋白(glycosylated hemoglobin,Hb A1c)与C反应蛋白(C-reactive protein,CRP)的关系,本研究检测了GDM患者血糖、血清Hb A1c与CRP水平,并对Hb A1c与CRP的相关性进行了分析。方法:以68例2015年4月至2017年4月于我院诊治的GDM孕妇为研究对象,所有患者均符合《妇产科学》中关于GDM的诊断标准,另选取68例正常孕妇为对照组。采用葡萄糖氧化酶法检测血糖水平(空腹血糖及餐后2 h血糖水平),采用免疫凝集法检测和比较两组血清糖化血红蛋白(HbA1c)水平,采用免疫透射比浊法检测血清C反应蛋白(CRP)水平,并分析HbA1c与CRP的相关性。结果:GDM组患者空腹血糖(fasting plasma glucose,FPG)、2 h血糖(plasma glucose,PG)、血清HbA1c和CRP水平均显著高于正常组(P0.05),GDM患者血清Hb A1c和CRP水平呈显著正相关关系(r=0.654,P0.05)。结论:GDM患者血清HbAlC和CRP水平相较于正常孕妇有显著提高,且二者呈显著的正相关关系,二者联合检测可能作为GDM早期诊断的筛查的重要参考指标。     

The role of serum fructosamine as a screening test for gestational diabetes mellitus

The serum fructosamine concentration indicates the degree of glycation of serum proteins, particularly albumin, and reflects an average blood glucose level over the previous 1-3 weeks. Serum fructosamine, glycated haemoglobin (HbA1c), total serum protein, serum albumin, fasting plasma glucose and oral glucose tolerance test (OGTT) have been measured in 127 healthy control subjects, 102 type 1 and 152 type 2 diabetes mellitus patients and 106 nondiabetic pregnant women. Fructosamine concentration of 2.24 +/- 0.16 and 3.21 +/- 0.41 mmol/l (mean +/- S.D.) has been found in control subjects and diabetics respectively (P less than 0.001). During the second trimester a significantly lower fructosamine level (1.92 +/- 0.21 mmol/l) has been found in pregnant women, most likely due to the low serum albumin concentration (31.35 +/- 3.97 g/l). None of them had a fructosamine level above the normal limit of 2.55 mmol/l. On the other hand, 12 pregnant women showed a disturbed OGTT with normal fructosamine. If the serum fructosamine concentration was adjusted for 40 g/l albumin, then a mean fructosamine of 2.16 +/- 0.24 mmol/l was found in patients with gestational diabetes. Our results show that serum fructosamine has a similar diagnostic value as HbA1c for non-pregnant adults, but neither can replace OGTT for the diagnosis of gestational diabetes.     

Increased circulating heat shock protein 70 (HSPA1A) levels in gestational diabetes mellitus: a pilot study

Recent data indicate that serum Hsp70 (HSPA1A) levels are increased in type 1 and 2 diabetes mellitus. However, there is no report in the literature on circulating Hsp70 levels in gestational diabetes mellitus. In this pilot study, we measured serum Hsp70 levels in 11 pregnant women with pregestational diabetes, 38 women with gestational diabetes, and 40 healthy pregnant women with ELISA. Plasma glucose levels, serum insulin concentrations, HbA1c values, and the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) index were also determined. According to our results, serum Hsp70 concentrations were significantly higher in women with pregestational and gestational diabetes mellitus than in healthy pregnant women. In addition, pregestational diabetic women had significantly higher Hsp70 levels than those with gestational diabetes. Furthermore, in the group of women with gestational diabetes mellitus, serum Hsp70 levels showed a significant positive correlation with HbA1c values. However, there was no other relationship between clinical features and metabolic parameters of the study subjects and their serum Hsp70 levels in either study group. In conclusion, we demonstrated for the first time in the literature that serum Hsp70 levels are increased and correlate with HbA1c values in women with gestational diabetes mellitus. Nevertheless, further studies are needed to determine whether circulating Hsp70 plays a causative role in the pathogenesis of gestational diabetes or elevated serum Hsp70 levels are only consequences of the disease.     

Treatment of Diabetes Mellitus in Dogs Using Isophane Insulin Penfills and the Use of Serum Fructosamine Assays to Diagnose and Monitor the Disease

The objectives of the study were to test the use of a prefilled insulin syringe (Insulatard® Novolet®, isophane insulin, 100 IU/mL) in treating diabetic dogs and to test the clinical usefulness of serum fructosamine measurements in diagnosing and monitoring diabetes mellitus in dogs. For this study 15 dogs from throughout Norway with newly diagnosed diabetes mellitus were included and treated over a period of 180 days. All 15 dogs showed pretreatment hyperglycaemia. Of the 13 dogs tested, all showed elevated pretreatment serum fructosamine values. Within 2 weeks, 3 of the 15 included dogs had dropped out of the study In 8 of the 12 remaining dogs, the clinical signs ceased within this period. Within a month, another dog was euthanised and one had died. Seven of the 10 remaining dogs were clinically normal. Three dogs had normal serum fructosamine concentrations, while in 6 dogs moderately or highly elevated serum fructosamine concentrations persisted. In one case serum fructosamine was not measured at this time. Increase in serum fructosamine concentration seemed to reflect hyperglycaemia and deteriorated clinical condition. Decrease in serum fructosamine concentration seemed to reflect improved glycaemic status and clinical condition. During the study period the owners did a total of approximately 3500 injections on their dogs. No reports of injection difficulties were received. This study documents that Insulatard® Novolet® is easy and safe to use in treating diabetic dogs and that serum fructosamine reflects long-term glucose concentrations in dogs. Serum fructosamine measurements provided a simple and easy way to diagnose persistent hyperglycaemia and monitor the treatment in diabetic patients.     

Glucose tolerance disorders in patients with cancer of the colon

Relating to the Williams' report suggesting twofold higher incidence of diabetes mellitus in patients with the cancer of the colon, the study aiming at comparing an incidence of diabetes mellitus in patients with stomach, lung, and colon malignancies were carried out. Coexistence of the above listed neoplasms with diabetes mellitus type II was assessed in patients hospitalized at the Department of Gastroenterology and Metabolic Diseases, Institute of the Internal Diseases, Medical Academy in Warsaw within 1978-1986. Moreover, glycaemia and insulinemia curves were plotted following oral glucose load (75 g) in 16 patients with the cancer of the colon and 15 patients without malignancy. Only patients with body weight not exceeding 10% of the normal body weight, without history of diabetes mellitus and not treated with corticosteroids were classified for the study. Mean glycaemia and insulinemia values did not differ statistically in the investigated groups except statistically significantly higher serum insulin level in patients with cancer of the lung in the thirties minute of the test. Differences statistically significant were also not observed in retrospective analysis. However, an incidence of diabetes mellitus in patients with the cancer of the colon was 10.5% being higher than mean incidence of diabetes mellitus in this age group. Moreover, glucose load test has shown tolerance abnormalities in 4 patients with cancer of the colon, 1 patient with cancer of the lung, and 1 patient without malignancy. The obtained results indicate tendency to higher incidence of carbohydrate metabolism disorders in patients with cancer of the colon.     

Lipid metabolism in patients with insulin dependent diabetes. III. Effect of metabolic control of diabetes on the concentration of some blood serum lipid constituents in patients with insulin dependent diabetes]

The levels of the following blood serum lipid constituents: total cholesterol, triglycerides, phospholipids, HDL-cholesterol, lipoprotein fractions, as well as apolipoproteins AI, AII and B, have been determined in patients with insulin-dependent diabetes lasting from 3 months to 15 years in relation to the degree of metabolic control characterized by the levels of fructosamine and glycosylated hemoglobin HbA1c. The group of patients having the level of HbA1c exceeding 10% was characterized by significantly higher levels of cholesterol, triglycerides and Apo-B, and lower content of alpha-lipoprotein as compared to the group with HbA1c level beneath 10%. When fructosamine concentration was considered as an index of metabolic control of diabetes, it was found that the levels of cholesterol, phospholipids and apolipoproteins apo-A and apo-AI are highest in the group with the poor metabolic control and differ significantly from the respective values found in patients with mediocre and good metabolic control. Considering biological role of the individual lipids and lipoproteins, it should be stressed that the proper control of glycaemia is important for preventing the development of atherosclerosis in patients with insulin-dependent diabetes.     

Elemental contents in serum of pregnant women with gestational diabetes mellitus

Diabetes mellitus is characterized by hyperglycemia and is closely related to trace elements. Quite a few pregnant women suffer from impaired glucose tolerance (IGT) or gestational diabetes mellitus (GDM). Investigation of the changes of elemental contents in serum of the pregnant women with IGT and GDM is significant in the etiological research and cure of the diseases. In the present work, the elements Cu, Zn, Ca, Sr, Mg, P, Fe, and Al in the serum of pregnant women were determined. The elemental contents in different experimental groups were compared. Also, the correlation between elemental contents and gestational period was observed. The results showed that compared with normal pregnant women, the Cu contents in serum of pregnant women with GDM increased, but Zn contents had a decreasing trend. In addition, for all pregnant women, the Ca contents in serum had an obvious inverse correlation with gestational period.     

Serum fructosamine concentration as measure of blood glucose control in type I (insulin dependent) diabetes mellitus.

Serum fructosamine activity was studied in 42 patients with type I (insulin dependent) diabetes mellitus and 30 non-diabetic volunteers as an index of blood glucose control. There was a significant correlation both between fructosamine and glycosylated haemoglobin values (r = 0.82) and between fructosamine and the fasting C peptide concentration (r = -0.81). Test results in 14 of the diabetics reflected the mean plasma glucose concentration calculated from 25 serial estimations in a single 24 hour period (r = 0.75; p less than 0.01) but not the mean amplitude of glycaemic excursion (r = 0.23; p greater than 0.05). Fructosamine concentrations measured in these multiple blood specimens did not change significantly throughout the day (mean coefficient of variation 4.1%) despite wide variability of the respective plasma glucose concentrations (mean coefficient of variation 36.2%). It is concluded that a single random serum sample analysed for fructosamine concentration provides a simple and reliable assessment of glucose homoeostasis in patients with type I diabetes mellitus.

Evaluation of Serum Selenium Levels in Turkish Women with Gestational Diabetes Mellitus, Glucose Intolerants, and Normal Controls

The aim of the study was to investigate the association between serum selenium levels in patients with gestational diabetes mellitus (GDM) and glucose intolerants and compare them with those of glucose-tolerant pregnant women. This cross-sectional study was prospectively performed in a total of 178 pregnant women undergoing a 50-g oral glucose tolerance test between 24 and 28 weeks of gestation who were grouped according to their status of glucose tolerance as with gestational diabetes (group A, abnormal 1- and 3-h glucose tolerance test; n = 30), glucose intolerant (group B, abnormal 1-h but normal 3-h glucose tolerance test; n = 47), or normal controls (group C, normal 1-h glucose test; n = 101). Serum selenium levels were measured with a graphite furnace atomic absorption spectrophotometer using a matrix modifier. Median maternal age and gestational age at the time of diagnosis in group A (gestational age = 24.8 [24-27]), group B (gestational age = 24.7 [24-27]), and group C (gestational age = 25 [24-28]) did not differ. Patients with gestational diabetes mellitus and those with glucose intolerants had lower selenium level than that of the normal pregnant women (P < 0.001). There was a significant inverse correlation between selenium and blood glucose level, and also selenium supplementation might prove beneficial on patients with GDM and prevent or retard them from secondary complications of diabetes.     

The Shepherds’ Tale: A Genome-Wide Study across 9 Dog Breeds Implicates Two Loci in the Regulation of Fructosamine Serum Concentration in Belgian Shepherds

Diabetes mellitus is a serious health problem in both dogs and humans. Certain dog breeds show high prevalence of the disease, whereas other breeds are at low risk. Fructosamine and glycated haemoglobin (HbA1c) are two major biomarkers of glycaemia, where serum concentrations reflect glucose turnover over the past few weeks to months. In this study, we searched for genetic factors influencing variation in serum fructosamine concentration in healthy dogs using data from nine dog breeds. Considering all breeds together, we did not find any genome-wide significant associations to fructosamine serum concentration. However, by performing breed-specific analyses we revealed an association on chromosome 3 (p_corrected ≈ 1:68 × 10^-6) in Belgian shepherd dogs of the Malinois subtype. The associated region and its close neighbourhood harbours interesting candidate genes such as LETM1 and GAPDH that are important in glucose metabolism and have previously been implicated in the aetiology of diabetes mellitus. To further explore the genetics of this breed specificity, we screened the genome for reduced heterozygosity stretches private to the Belgian shepherd breed. This revealed a region with reduced heterozygosity that shows a statistically significant interaction (p = 0.025) with the association region on chromosome 3. This region also harbours some interesting candidate genes and regulatory regions but the exact mechanisms underlying the interaction are still unknown. Nevertheless, this finding provides a plausible explanation for breed-specific genetic effects for complex traits in dogs. Shepherd breeds are at low risk of developing diabetes mellitus. The findings in Belgian shepherds could be connected to a protective mechanism against the disease. Further insight into the regulation of glucose metabolism could improve diagnostic and therapeutic methods for diabetes mellitus.

A comparison of the effectiveness, tolerability and safety of high and low carbohydrate diets in women with gestational diabetes

INTRODUCTION: Nutrition therapy is an integral part of the management of gestational diabetes mellitus (GDM). Most women with GDM are treated by nutritional management alone. The goal of our study was to compare low and high carbohydrate diets in their effectiveness, safety and tolerability in women with GDM. MATERIAL AND METHODS: The study group consisted of 30 Caucasian women newly diagnosed with GDM, with a mean age of 28.7 +/- 3.7 years and pregnancy duration of 29.2 +/- 5.4 weeks. The patients were randomised into two groups: those on a low and those on a high carbohydrate diet (45% vs. 65% respectively of energy supply coming from carbohydrates). The presence of urine ketones was controlled every day. After two weeks daily glucose profiles and compliance with the recommended diets were analysed. RESULTS: Glucose concentration before implementation of the diet regimen did not differ between groups. No changes in fasting blood glucose were noticed in the group that had followed a low carbohydrate diet, although a significant decrease in glucose concentration was observed after breakfast (102 +/- 16 vs. 94 +/- 11 mg/dl), lunch (105 +/- 12 vs. 99 +/- 9 mg/dl) and dinner (112 +/- 16 vs. 103 +/- 13 mg/dl) (p < 0.05). In the high carbohydrate diet group fasting and after-breakfast glucose concentration did not change. A significant decrease in glycaemia was noticed after lunch (106 +/- 15 vs. 96 +/- 7 mg/dl) and dinner (107 +/- 12 vs. 97 +/- 7 mg/dl) (p < 0.05). Ketonuria was not observed in either group. Obstetrical outcomes did not differ between groups. CONCLUSIONS: Both high and low carbohydrate diets are effective and safe. A diet with carbohydrate limitation should be recommended to women who experience the highest glycaemia levels after breakfast.     

Pilot Study to Evaluate the Effect of Short-Term Improvement in Vitamin D Status on Glucose Tolerance in Patients With Type 2 Diabetes Mellitus

ObjectiveTo study the effect of improvement in vitamin D status on glucose tolerance in Asian Indian patients with moderately controlled type 2 diabetes mellitus (T2DM).MethodsThis randomized, double-blind, placebocontrolled pilot study was conducted in 28 Asian Indian patients with T2DM. Study participants were randomly assigned to a vitamin D-treated group (group D) or a placebo group (group P). Serum 25-hydroxyvitamin D, hemoglobin A1c, and serum fructosamine levels were measured, and an oral glucose tolerance test (OGTT) was performed in all patients at baseline and 4 weeks after intervention. During the OGTT, plasma glucose and serum insulin levels were measured at 0, 30, 60, 90, and 120 minutes. The unpaired t test was used to compare the groups at baseline and to compare the differences in changes from baseline to 4 weeks between the 2 study groups.ResultsGroup D and group P were similar with respect to their fasting plasma glucose and serum insulin concentrations, post-OGTT plasma glucose and serum insulin levels, and hemoglobin A1c and fructosamine values at baseline. Serum 25-hydroxyvitamin D levels increased significantly in group D at 4 weeks. No significant differences were found between the groups at baseline and 4 weeks with respect to serum fructosamine, fasting plasma glucose and serum insulin, post-OGTT plasma glucose and serum insulin levels, and homeostasis model assessment of insulin resistance.ConclusionIn this study, short-term improvement in vitamin D status was not associated with improvement in glucose tolerance, insulin secretion, or insulin sensitivity in Asian Indian patients with moderately controlled T2DM.(Endocr Pract. 2010;16:600-608)

Metabolic syndrome in type 1 diabetes mellitus. Does it have any impact on the course of pregnancy?

To determine whether the symptoms of metabolic syndrome (MS), if accompanied by oxidative stress (OS), in type 1 diabetes mellitus (DM) patients could affect the course of pregnancy and the perinatal outcome. Oxidized low density lipoproteins (ox-LDL) and total lipid peroxides (TLP) were studied in 98 pregnant women with type 1 DM in the I(st) and III(rd) trimesters. 24% of the participants met the criteria of MS. Vascular complications were significantly more frequent in the MS-group (41.9% vs. 17.4% in the non-MS group, p<0.05). No differences in the markers of OS between the MS and the non-MS groups were noted in either the I(st) or the III(rd) trimester. A significant gestational rise in Per-Ox was found in both groups. Chronic hypertension was associated with significant differences in ox-LDL levels in both the I(st) and III(rd) trimester. No differences in perinatal outcome, as measured by abnormal birth weight or poor neonatal status (Apgar score<6, umbilical venous and/or arterial pH<7.20), were found. Conclusions: 1) MS in type 1 DM is associated with some changes in markers of oxidative stress, but it poses no additional risk to the course of pregnancy and perinatal outcome in properly controlled and treated pregnant women with type 1 DM. 2) Maternal hypertension is the only component of MS in diabetic pregnancy that is associated with significant changes in markers of oxidative stress. 3) MS is significantly more frequent in diabetic pregnant women with co-existing vascular complications and obesity.     

Changes of serum selenium in pregnant women with gestational diabetes mellitus

Gestational diabetes is one of the most common diseases in pregnancy. In the present work, the possible relationship between serum selenium concentration and gestational diabetes was investigated. Blood samples of 234 pregnant women were collected, including 98 subjects with impaired glucose tolerance (IGT), 46 subjects with gestational diabetes mellitus (GDM), and 90 normal pregnant women (NPW). An additional 17 samples of normal women of fertile age (NW) were collected for comparison. The hydride generation atomic fluorescence spectrometry was used for selenium determination. The mean serum selenium levels obtained for each group were 0.0741±0.0167 mg/L for NPW, 0.0631±0.0132 mg/L for IGT, 0.0635±0.0120 mg/L for GDM, and 0.108±0.0170 mg/L for NW. Serum selenium levels were significantly lower in pregnant woman with IGT (p<0.001) and GDM (p<0.001) than in NPW. Furthermore, an inverse correlation between the serum selenium concentration and the gestational period was also observed. Selenium supplementation during gestation for pregnant women, especially with IGT and GDM, should be considered.

Insulin therapy and its consequences for the mother,foetus, and newborn in gestational diabetes mellitus

Gestational diabetes mellitus (GDM) is a disease characterised by glucose intolerance and first diagnosed in pregnancy. This condition relates to an anomalous placental environment and aberrant placental vascular function. GDM-associated hyperglycaemia changes the placenta structure leading to abnormal development and functionality of this vital organ. Aiming to avoid the GDM-hyperglycaemia and its deleterious consequences in the mother, the foetus and newborn, women with GDM are firstly treated with a controlled diet therapy; however, some of the women fail to reach the recommended glycaemia values and therefore they are passed to the second line of treatment, i.e., insulin therapy. The several protocols available in the literature regarding insulin therapy are variable and not a clear consensus is yet reached. Insulin therapy restores maternal glycaemia, but this beneficial effect is not reflected in the foetus and newborn metabolism, suggesting that other factors than d-glucose may be involved in the pathophysiology of GDM. Worryingly, insulin therapy may cause alterations in the placenta and umbilical vessels as well as the foetus and newborn additional to those seen in pregnant women with GDM treated with diet. In this review, we summarised the variable information regarding indications and protocols for administration of the insulin therapy and the possible outcomes on the function and structure of the foetoplacental unit and the neonate parameters from women with GDM.     

妊娠期糖尿病患者妊娠中期体质指数水平对分娩结局的影响

目的:研究妊娠期糖尿病患者妊娠中期体质指数(BMI)水平对妊娠结局的影响。方法:选取2012年1月到2014年11月我院产检诊断为妊娠期糖尿病患者390例,根据患者的妊娠中期BMI水平由低到高依次将患者分为三组:I组119例,II组165例,III组106例,随访所有入选者至分娩,观察其分娩结局。结果:III组妊娠晚期出现巨大胎儿者24例,占22.64%,羊水过多者为26例,占24.53%,显著高于I组和II组,比较差异具有统计学意义(P0.05);III组出现妊娠期高血压者8例,占7.55%,新生儿窒息者4例,占3.77%,与I组和II组比较差异无统计学意义(P0.05)。结论:妊娠期糖尿病患者妊娠中期BMI较高者发生巨大儿和羊水过多的比率显著增加,应该适当控制妊娠期糖尿病患者的BMI水平。
