The present study was undertaken in 100 subjects, 30 diabetics without complication (group I), 40 diabetics with retinopathy
(group II) and 30 non diabetic as normal control group (group III). Blood sugar levels, magnesium, cholesterol and triglyceride
were analyzed from plasma and serum. The results were correlated with degree of diabetic control from the levels of glycosylated
hemoglobin. Serum magnesium levels in group II were found to be significantly lowered than in group I. There was also significant
difference in magnesium levels of group I and group III. We found a significant correlation between the glycosylated hemoglobin
and magnesium levels in our study.
The results also indicate that the patients with diabetic retinopathy showed significant rise in serum cholesterol and triglyceride.
Probably hypomagnesemia and increased serum cholesterol and triglyceride levels are responsible for microvascular changes
in diabetes leading to retinopathy. The purpose of this study was thus to gather information about the degree of control of
diabetes and magnesium status. 相似文献

Patients with type II Diabetes Mellitus (NIDDM) are more prone to Ischaemic Heart Disease (IHD). Although, oxygen free radicals
are known to contribute to the development of IHD, conflicting reports are available regarding the antioxidant status in patients
of NIDDM complicated with IHD. This study was undertaken to investigate the oxidative status in patients of NIDDM and to assess
their correlation with plasma glucose, glycosylated haemoglobin and duration of diabetes. The levels of malondialdehyde were
significantly increased where as levels of superoxide dismutase, Glutathione peroxidase and vitamin C were significantly decreased
in diabetics without complications and non-diabetics with IHD when compared with the controls. The levels of malondialdehyde
and Glutathione peroxidase were significantly increased where as levels of superoxide dismutase and vitamin C were significantly
decreased in diabetics with IHD when compared with diabetics without complications and non-diabetics with IHD. The implications
of the results are discussed. 相似文献

The glycosylated haemoglobin was measured in two different categories of diabetic subjects. In poorly controlled subjects
of group II, a significant alteration in serum proteins was observed. Total protein along with albumin concentrations were
decreased and α2 globulin fraction was increased. Insulin therapy resulted in normalisation of blood glucose and gradual decrease in glycosylated
haemoglobin in the therapy period of eight weeks. This also resulted in a rise of total protein and albumin concentrations
with a decrease in α2 fraction. The present study indicates that prolonged therapy of insulin is needed to correct the serum protein abnormalities
in diabetics. 相似文献

Homeostatic Model Assessment-Insulin Resistance (HOMA-IR 2) in Mild Subclinical Hypothyroid Subjects
Shreejita Sengupta T. Jaseem Jayachidambaram Ambalavanan Anupama Hegde 《Indian journal of clinical biochemistry : IJCB》2018,33(2):214-217
Despite various studies with conflicting results, the effect of thyroid hormones on lipids and insulin levels in dysthyroidism is of great interest. This case control study was aimed to perceive the existence of IR and dyslipidemia in mild subclinical hypothyroid subjects (TSH ≤ 9.9 µIU/ml) as compared to their age and gender matched euthyroid controls. Basic demographic information like height, weight was recorded. Serum samples of all the subjects were assayed for thyroid profile, lipid profile, blood glucose, HbA1C and insulin. BMI and insulin resistance was calculated. Compared to controls patients with mild subclinical hypothyroidism demonstrated hyperinsulinemia and dyslipidemia observed by the higher LDL cholesterol. A significantly positive correlation was observed for HOMA-IR with TSH and LDL cholesterol. Hence, even in the mild subclinical hypothyroid state assessment of thyroid function should be combined with estimation of plasma glucose, insulin and serum lipids to monitor and prevent its associated effects. 相似文献

Non-insulin dependent diabetes mellitus (NIDDM) is the most rapidly growing chronic metabolic disorder in the world. With
advancement in the age and duration of diabetes there is a gradual tendency for the level of blood sugar to rise along with
a subsequent increase in the HbA1c as well as in the fasting insulin level. Whether this is an aging process or increased
frequency of diabetes is still controversial. The correlation between glucose and insulin sensitivity is consistent with the
idea that the degree of chronic hyperglycemia is a cause of excessive insulin resistance in type 2 diabetes, i.e. the insulin
resistance which characterizes type 2 diabetes but not nondiabetic subjects matched for age, gender, family history and duration
of diabetes. The study comprised a total of 76 subjects out of which 30 were normal, non-diabetic persons and the rest 46
were diabetics with different duration of time in years, after being diagnosed diabetic. Data was analyzed after dividing
the subjects into four groups—Group 1 comprised of one year old diabetics, Group 2 was made up of those, who had diabetes,
for the past 2–5 years, Group 3 included patients who were diabetic since more than 5 years and Group 4 included non-diabetics
as the normal control group. The results obtained indicated that the HbA1c levels showed a significant increase with the duration
of diabetes as well as the insulin level showed a significant correlation after adjustment for age, sex and duration of diabetes. 相似文献

Diabetes mellitus and thyroid disorders are common endocrinopathies, which often occur parallel. Dyslipidemia is very common in both of these conditions. The development of hypothyroidism is well-known in type 1 diabetics, but it was not distinctly understood in type 2 diabetics. Thus we tried to examine the association between type II deiodinase (D2 or DIO2) Thr92Ala single nucleotide gene polymorphism and thyroid function among type 2 diabetes mellitus patients. A total of 130 type 2 diabetics were screened and genotyped for DIO2 Thr92Ala polymorphism. Fasting plasma glucose, Glycosylated haemoglobin, lipid and thyroid profiles, malondialdehyde (MDA) and paraoxonase were estimated according to standard procedures. A significant altered level of thyroid hormones (TH’s) was found in Ala/Ala genotype when compared with Thr/Thr or Thr/Ala genotype. DIO2 and T3:T4 ratio significantly decreased, whereas total T4 and thyroid stimulating hormone levels significantly elevated among Ala/Ala genotype (131 ± 30 ng/ml; 0.12 ± 0.05; 7.17 ± 2.05 µg/dl; 4.77 ± 3.1 µIU/ml, respectively) when compared with Thr/Thr + Thr/Ala genotypes (176 ± 33 ng/ml; 0.21 ± 0.05; 5.21 ± 1.1 µg/dl; 2.59 ± 1.61 µIU/ml respectively). Moreover, D2 levels were significantly negatively correlated with TH’s levels except total T4 among Ala/Ala genotypes. All the patients were having a poor glycemic control, and their glycemic status was positively correlating with MDA levels. On the other hand, serum paraoxonase activity decreased among Ala/Ala genotype (104 ± 21 vs. 118 ± 18 nmol/min/ml). In conclusion, DIO2 Ala92 homozygous variant found to be associated with altered levels of DIO2, Thyroid profile and paraoxonase. Hence, we recommend to do detail study of genetic factors related to thyroid function and prevent additional diabetic complications. 相似文献

Diabetes Mellitus in obese and non-obese Indian individuals.AIMS: Effect of Obesity and insulin resistance on diabetic control.SETTINGS AND DESIGN: 50 each groups Diabetic individuals obese and non-obese.METHODS AND MATERIAL: On selected 50 each group diabetic patient and normal, following blood investigations has been performed—Plasma Glucose,
Glycohemoglobin and Serum Insulin.STATISTICAL ANALYSIS USED: Individuals patient’s results were analyzed and compared with the normal controls.RESULTS AND CONCLUSION: The changes in glycosylated haemoglobin are mainly proportional to the post lunch glucose level (r=0.773) (p<0.01) and not
correlated to circulating insulin or the body mass index. However the levels were higher in obese diabetes (Type I and II
both) than in non-obese. Mechanism of resistance in insulin receptor interactions due to obesity is well known. However, obesity
does not seem to affect directly glycosylated haemoglobin. Under such circumstances, the reduction of weight for a diabetic
person can improve sugar control by minimizing insulin resistance and thereby can improve glycosylated haemoglobin levels. 相似文献

Type 2 diabetes is associated with a marked increase in the risk of coronary artery disease. Dyslipidaemia is believed to
be a major cause of this increased risk. Recently, elevated levels of lipoprotein (a), Lp(a), have been reported to be associated
with an increased risk. However there is very little data regarding Lp(a) concentrations and type 2 diabetes from India. The
objective of the study was to assess serum Lp(a) levels in type 2 diabetics with and with out evidence of clinical nephropathy.
We estimated serum Lp(a) levels in 30 control subjects, 30 diabetics without evidence of clinical nephropathy and 30 diabetics
with evidence of clinical nephropathy. Statistical analysis showed that Lp(a) levels were increased in diabetic patients with
nephropathy (mean 46.3±17.6 mg/dl). The Lp(a) levels however did not differ significantly between control (mean 20.2±15.9
mg/dl) and diabetics without nephropathy (mean 22.6±13.1mg/dl). Thus diabetes per se seems to have little or no influence
on serum Lp(a) levels, however elevated levels were seen in patients with nephropathy. 相似文献

Free iron in serum has been found in several disease conditions including diabetes. In the present work, we studied the relationship
between free iron, fasting blood glucose (FBG) and glycated haemoglobin (HbA1c). Study was carried out on 50 type 2 diabetes cases under poor glycemic control associated with complications, 53 type 2
diabetes cases under good glycemic control and 40 healthy controls. We estimated free iron, both ferrous (Fe+2) and ferric (Fe+3) form, protein thiols, lipid hydroperoxides, FBG, HbA1c and serum ferritin levels in serum. There was a significant increase
in free iron in Fe+3 state (p <0.01), HbA1c (p<0.01), serum ferritin (p<0.01), lipid hydroperoxides (p<0.01) and significant decrease in protein thiols (<0.01) in diabetes
cases under poor glycemic control compared to diabetes cases under good glycemic control and healthy controls. Free iron correlated
positively with HbA1c (p<0.01). Poor glycemic control and increase in glycation of haemoglobin is contributing to the increase in free iron pool
which is known to increase oxidant generation. 相似文献

A distinguishable feature of type 2 diabetes besides hyperglycemia and deranged lipid profile is an impaired insulin secretion,
peripheral insulin resistance and obesity which has become a major health concern worldwide. India with an estimated 31million
diabetics in 2000 and 79mllions by the yr 2030 has the highest number of type 2 diabetics in the world. In this study, we
aimed to see if yoga-asanas and pranayamas have any influence in modifying certain biochemical parameters. Sixty patients
of uncomplicated type 2 diabetes (age 35–60 yrs of 1–10 yrs duration) were divided into two groups: Group 1 (n=30): performed
yoga along with the conventional hypoglycemic medicines and group 2 (n=30): patients who only received conventional medicines.
Duration of the study was 45 days. Basal recordings of blood glucose (fasting and post-prandial), lipid profile and serum
insulin were taken at the time of recruitment and the second reading after forty five days. Results showed a significant improvement
in all the biochemical parameters in group 1 while group 2 showed significant improvement in only few parameters, thus suggesting
a beneficial effect of yoga regimen on these parameters in diabetic patients. 相似文献

There is a rising trend in the prevalence of insulin resistance among obese, overweight children and adolescents. The serum
insulin and its correlation with biochemical, clinical and anthropometric parameters were evaluated in 185 children and adolescents
(59 control, 52 obese, 49 overweight, 25 congenital heart disease) of age group 10–17 years. The levels of serum insulin were
measured by ELISA. Serum insulin levels were found to be significantly increased in children who were obese, overweight and
had congenital heart disease, than controls. Serum insulin levels positively correlated with BMI, WHR, and serum C-peptide,
serum leptin, total cholesterol, triglycerides, LDL-cholesterol, systolic and diastolic blood pressure. Fasting glucose levels
were found to be negatively correlated with serum insulin levels. HDL-cholesterol levels were non-significant among the study
groups. We identified nine obese children (five girls and four boys) with the features of metabolic syndrome and 69% of obese
and overweight children were identified with insulin resistance. Insulin resistance was strongly associated with metabolic
syndrome and its components, especially with central obesity and hypertriglyceridemia. 相似文献

In persons with impaired glucose tolerance, serum glycated proteins (9.44±1.46μg hexose/mg protein) increased 1.69-fold (P<0.001)
over control subjects compared to an increase of 1.95-fold in overt diabetics. However, correlations between serum glycated
protein values and 2 h blood sugar values during the tolerance test (r=0.39) and between the former and graph area (r=0.30)
were not strong. Glycated albumin (2.25 mol hexose/mol protein) and glycated haemoglobin (0.398±0.07 mol hexose/mol protein)
in the study group also showed 1.67 and 1.24-fold increase respectively compared to controls. Fairly good correlations between
glycated serum protein and glycated albumin (r=0.50) and glycated haemoglobin (r=0.45) were observed during this study. The
data suggest that measurement of glycated proteins will be a useful index to detect impaired glucose tolerance. 相似文献

The study was designed to find out the correlation between lipid peroxidation, lipoprotein levels to severity and complication
of diabetes mellitus. Degree of lipid peroxidation was measured in terms of malondialdehyde (MDA) along with lipid profile
and blood glucose in diabetes mellitus. It is categorised into insulin dependent diabetes mellitus (IDDM), non insulin dependent
diabetes mellitus (NIDDM) and diabetes mellitus(DM) with complication.
Total 112 known diabetic patients and 52 non-diabetic controls were studied. These patients were grouped as per the concentration
of fasting blood glucose level i.e. controlled, poorly controlled, and uncontrolled group. There are significant increase
in the lipid peroxide (MDA) and lipid profile except HDL cholesterol which is decreased, has been found in all groups as compared
to controls In NIDDM group lipid peroxidation was markedly increased than IDDM group and it was higher in DM with complications.
Other finding observed was that the level of lipid peroxide increased as per the increase in concentration of blood glucose.
The increase lipid peroxidation in the hyperglycemic condition may be explained, as the superoxide dismutase enzyme which
is antioxidant becomes inactive due the formation of superoxide radical within the cell. Maximum lipid peroxidation leads
to the damage of the tissue and organs which results into complication in diabetic patients. High levels of total cholesterol
appear due to increased cholesterol synthesis. The triglyceride levels changes according to the glycemic, control. The increase
may be due to overproduction of VLDL-TG.
It is concluded that good metabolic control of hyperglycemia will prevent in alteration in peroxidation and the lipid metabolism,
which may help in good prognosis and preventing manifestation of vascular and secondary complication in diabetes mellitus. 相似文献

In the present study, 58 diabetic patients (type II) comprising uncomplicated (27) and complicated (31) cases along with 38 healthy matched controls were investigated for glycosylated hemoglobin (HbA1), glycosylated serum proteins (GSP) and serum lipid profile viz. triacylglycerol, total cholesterol, HDL-cholesterol (HDL-C), VLDL-C, LDL-C and their ratios. HbA1 and GSP were significantly elevated in diabetic group as a whole when compared with controls (p<0.01), but comparison of mean values of complicated and uncomplicated group revealed (though higher in complicated) that the difference between two groups was not statistically significant (p>0.05). Follow-up studies showed that while GSP levels reflect variations in blood glucose over a shorter period of 15 days, those of HbA1 do so for about 3 months. HbA1 correlated with fasting blood glucose (p<0.01), whereas GSP showed correlation with both fasting (p<0.01) and postprandial (p<0.05) blood glucose. Hypercholesterolemia and hypertriacylglycerolemia were observed (p<0.01) in both the groups. However no significant change was seen in HDL-C (p>0.05) even after accounting for sex in both the groups. Interestingly TC:HDL-C was elevated significantly (p<0.01) in the above groups. These findings seem to suggest that at the levels of hyperglycemia, hypercholesterolemia and hypertriacylglycerolemia observed, some patients are prone to develop complications earlier. 相似文献

Picrorhiza kurrooa is mentioned in Ayurveda for the treatment of many disorders, but it has not been subjected to systematic
scientific investigations to assess its antidiabetic effect. The oral administration of aqueous and methanol extracts of P.
kurrooa rhizomes (250 and 500 mg / kg body weight / day) for 15 days significantly reduced blood glucose, glycosylated haemoglobin
and increased total hemoglobin, plasma insulin in alloxan-induced diabetes in albino rats. The treatment also showed significant
correction in the level of nitric oxide radicals, superoxide radicals, peroxynitrite radical, lipid peroxidation, glutathione,
glutathione reductase, glutathione-S-transferase, glutathione peroxidase, superoxide dismutase and catalase in the pancreas
of alloxan diabetic rats. 相似文献

Glycosylated Hemoglobin (GHb) was estimated using cation exchange resin binding method in 50 non diabetic healthy controls and 500 maturity onset diabetics. Percentage of glycosylated hemoglobin levels in controls was 7.27±0.456 (range 6.0–8.04) and 9.47±0.98 (range 8.2–13.63) in diabetic group. Glycosylated hemoglobin levels remain unaffected inspite of transient rise of serum glucose levels during an oral glucose tolerance test. Significantly elevated GHb A1. Furthermore significant elevation of GHb A1 was noticed in diabetics with all secondary complications suggesting poor glycemic control in these patients. The diabetics having retinopathy, nephropathy or diabetic foot had relatively higher GHb levels compared to patients having coronary artery disease or hypertension. 相似文献

The cause of more insulin resistance in female than males are still unknown. To know the cause from early life, normal values of relevant parameters are required. So, aim of this study was to determine the reference levels of glucose and insulin in cord blood of term newborns and to examine their effects on gender, placental and birth weight of term newborns. In cross sectional study 60 consecutive term newborns were included from constituent hospitals. Placental and birth weights were measured and cord blood was collected for estimation of serum insulin and plasma glucose. Plasma glucose estimation was done by auto analyzer (GOD–POD method) and serum insulin analysis was done using Insulin ELISA Kit. After analysis, mean ± 2SD used for estimating cord blood insulin and glucose levels, which were 10.1 ± 7.8 μIU/mL and 67.8 ± 33.8 mg/dL respectively. Correlation of insulin with both birth weight and placental weight were r = 0.359 and 0.41 respectively; p < 0.001. Interestingly we found higher insulin levels in females as compared to male newborns in spite of having lower birth weight in them. In conclusion this study reported the levels of insulin and glucose in cord blood of term newborns. Incidentally, this is the first study as per our knowledge to report significant correlation between cord blood insulin, glucose with birth weight, placental weight and gender in south India. Female newborns had higher insulin levels than males, despite lesser birth weight can be attributed to intrinsic insulin resistance in them. 相似文献

Abdominal obesity (AO) has a strong correlation with cardiovascular disease and has been linked to Alzheimer’s disease and type 2 diabetes. We investigated the association between AO and elevated serum butyrylcholinesterase (BChE) activity, insulin resistance and the serum lipid profile, including triglyceride (TG), HDL-cholesterol (HDL-C) and LDL-cholesterol (LDL-C) levels in AO and non-AO women subjects. A total of 500 AO subjects (age 49.1 ± 10.5 years), and 142 non-AO women subjects (age 49.9 ± 11.9 years) were enrolled for the general biochemistry tests, serum BChE, fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR). Body mass index, waist circumference, Blood pressure (BP), plasma glucose (Glu), triglyceride (TG), BChE, insulin, HOMA-IR were significantly higher and HDL-C levels were significantly lower in AO subjects (p < 0.05). Waist circumference was significantly correlated with BP, Glu, TG, BChE, insulin and HOMA-IR in AO subjects. Multiple logistic regression demonstrated that AO was associated with elevated BChE, HOMA-IR, hypertension and reduced HDL-C after adjusting for these variables. AO is associated with elevated BChE, insulin resistance, HT and reduced HDL-C. These may predict the development of type 2 diabetes mellitus and may be associated with cognitive disorder in the future, both are mediated through insulin resistance. 相似文献
