Prevalence of overweight in urban Indian adolescent school children.

The prevalence of diabetes mellitus (DM) and cardiovascular disease (CVD) is increasing in urban India. Overweight in adolescence is a marker of overweight in adult age, and it shows an association with the above diseases. There have been meagre data from India on the prevalence of childhood obesity. The objective of the study was to quantify the prevalence of overweight and its risk factors in adolescent children in urban India. School students in the age group of 13-18 years (n = 4700, M:F 2382:2318) were studied. Body mass index (BMI) was measured. Data on physical activity, food habits, occupation of parents and their economic status, birth weight of the children and age at menarche in girls were obtained by questionnaire. Age-adjusted prevalence of overweight was 17.8% for boys and 15.8% for girls. It increased with age and was higher in lower tertiles of physical activity and in higher socio-economic group. Birth weight and current BMI were positively associated. The study highlighted the high prevalence of overweight in adolescent children in urban India. Life style factors influenced BMI in adolescent age.

Temporal changes in prevalence of type 2 diabetes and impaired glucose tolerance in urban southern India.

The prevalence of type 2 diabetes and impaired glucose tolerance (IGT) is increasing in urban areas of developing countries, especially in India. This is a report of the temporal changes in the prevalence of diabetes and IGT in urban areas of Chennai (Madras), India, in adults aged > or =20 years, with an emphasis on identifying the risk factors responsible for the changes. Three urban diabetic surveys conducted in 1989, 1995 and 2000 were compared for the age-standardized prevalence, anthropometric, demographic and lifestyle characteristics of the glucose-intolerant groups. Multiple logistic regression analyses were used for the identification of risk variables associated with diabetes and IGT. The trend was statistically significant for diabetes (chi(2)=18.0, P<0.001) and for IGT (chi(2)=48.2, P<0.001). The period between 1989 and 1995 showed a 40% rise in the prevalence of diabetes and a further increase of 16.4% in the next 5 years. Age increased in each survey for both genders. Waist girth and waist:hip ratio were significantly higher in women, in the 2000 survey. There was no change in the mean body mass index with time in both genders. An increase in IGT was seen in year 2000, especially so in subjects aged <40 years. The prevalence of diabetes and IGT is increasing in India. Increasing age and positive family history showed associations with diabetes.

Impact of poverty on the prevalence of diabetes and its complications in urban southern India.

AIM: The impact of poverty on the profile of diabetes and its complications was studied. METHODS: A comparative study of low income group (LIG) (family income Rs. < 30,000/annum (approx. 432 pounds sterling) and high income group (HIG) (family income Rs. greater-than-or-equal 60,000/annum (approx. pounds sterling) subjects of > or = 40 years was done in Madras, India. By screening 1748 LIG subjects (M/W 844/904) 301 diabetic subjects were identified and 218 underwent tests for diabetic complications. Population data available in 635 (M/W 309/326) HIG subjects from the survey were used for comparison of glucose tolerance profile. Complications were studied in 221 diabetic HIG subjects. RESULTS: Age-standardized prevalences of diabetes (12.6% vs. 25.5%; chi(2) = 56.9, P < 0.0001) and impaired glucose tolerance (IGT) (8.9% vs. 19.0%) were significantly lower (chi(2) = 57.7; P < 0.0001) in the LIG. Hypertension was more common in LIG (53.7% vs. 40.0% in HIG; chi(2) = 34.9; P < 0.0001). LIG subjects were more physically active; 73.8% did not go to school. Parameters significantly associated with diabetes were body mass index (BMI), age, higher income, waist--hip ratio and physical inactivity. Higher income, BMI and age were associated with IGT. Diabetic LIG subjects had a higher prevalence of cardiac disease, neuropathy and cataract and a lower prevalence of retinopathy than HIG subjects. The risk variables such as hyperglycaemia, dyslipidaemia, hypertension, smoking and alcohol consumption were more in the LIG group. CONCLUSIONS: The urban poor in the developing world has a lower prevalence of diabetes than the urban poor in developed societies. However, they have higher rates of complications of diabetes.

Early recognition of diabetic neuropathy: evaluation of a simple outpatient procedure using thermal perception.

OBJECTIVE: To determine the effectiveness of Tip-therm, a temperature discriminator, in making an early diagnosis of distal symmetrical polyneuropathy in diabetic patients and to compare its effectiveness with the Semmes-Weinstein monofilament and biothesiometry, which are established methods of diagnosing neuropathy in diabetic patients. PATIENTS AND METHODS: From the diabetic subjects who came to the hospital for review, 910 consecutive cases were selected. All were tested with the Semmes-Weinstein monofilament (10 g monofilament) and biothesiometry and also by using the Tip-therm for comparison. RESULTS: Out of the 241 patients who had no sensation to the monofilament only four (1.7%) felt Tip-therm whereas 237 (98.3%) patients could not feel Tip-therm. Among 298 patients diagnosed as having neuropathy by biothesiometry, only eight (2.7%) patients exhibited sensation with Tip-therm while 290 (97.3%) patients could not feel it. CONCLUSION: A simple device, Tip-therm, which tests for temperature discrimination, was compared with two validated methods for detection of neuropathy-a monofilament and biothesiometry. Tip-therm appears to be an inexpensive, highly sensitive, and specific device for detection of diabetic neuropathy when compared with biothesiometry and a monofilament.

Prevalence of pathogens in diabetic foot infection in South Indian type 2 diabetic patients.

AIM: To determine the prevalence of pathogens in diabetic foot infections, in relation to parameters like Wagner's grading, duration of diabetes and healing time. MATERIAL AND METHODS: A group of 654 (M:F, 433:221) type 2 diabetic patients with foot ulcers were studied. Specimens like pus, wound exudate and tissue were processed for smear for Gram's staining, aerobic and anaerobic culture, and biochemical identifications. RESULTS: In 654 diabetic patients, 728 pathogens were isolated. Aerobic pathogens were isolated in 437 (66.8%) patients and anaerobic pathogens were isolated in 217 (33.2%). As Wagner's grading increased, the prevalence of anaerobic pathogens also increased. Neuropathy was common in diabetic patients infected with both aerobic and anaerobic pathogens. Ulcers infected with anaerobic pathogens showed a longer healing time than ulcers infected with aerobic pathogens. There was no significant difference in peripheral vascular disease (PVD) in patients selected for the study. Among aerobic pathogens, Enterobacteriaceae family (48%), Staphylococcus species (spp) (18.2%), Streptococcus spp (16.8%) and Pseudomonas spp (17%) were seen frequently. Among anaerobes Peptostreptococcus spp and Clostridium spp formed 69.4%. Gram-negative anaerobes like Bacteroides spp and Fusobacterium spp were present in 30.6%. Healing time was longer when strict aerobic pathogen Pseudomonas spp and strict anaerobic pathogens were present (136.1 +/- 28.6 and 136.4 +/- 34.7 days, respectively). CONCLUSIONS: Diabetic foot infection is polymicrobial in nature. The healing time of wound infected with anaerobic pathogens was higher than those infected with aerobic pathogens. Anaerobic pathogens increased with the Wagner's grading. Presence of neuropathy increased the risk of foot infection.

Is increased apolipoprotein B-A major factor enhancing the risk of coronary artery disease in type 2 diabetes?

OBJECTIVES: An association of Apolipoprotein B (Apo B) with coronary artery disease (CAD) independent of LDL cholesterol (LDLc) concentrations has been reported in white population. This analysis was taken up to study whether the higher CAD risk in Asian Indians with diabetes could be explained by possible alterations in Apo B and Apolipoprotein A1 (Apo A1) concentrations. METHODS: The study group consisted of four hundred and forty seven men aged > or = 25 years, 167 with CAD and 280 with no CAD, classified by coronary angiography. Plasma lipid profile including total cholesterol, LDLc, Apo A1 and Apo B were done. Glucose tolerance was evaluated in all. RESULTS: Age, BMI, Apo B, and Apo A1 were significantly associated with CAD in a multiple regression analysis. Hyper Apo B was more common than hyper LDLc in CAD (73.6% vs 20.4%, chi2 = 157, P < 0.001). Apo B concentrations were increased in diabetic subjects even in the presence of normal levels of LDLc and in the absence of CAD. CONCLUSIONS: The study has shown that the apolipoproteins B and A1 provide better information regarding the risk of CAD. Apo B abnormalities exist in large percentages of CAD subjects despite having normal levels of LDLc. Diabetes per se enhances the Apo B concentrations and this could probably be one of the mechanisms of accelerated CAD in diabetes. Hyper Apo B may be an index of CAD risk.

Plasma homocysteine concentration and coronary artery disease in Asian Indians.

OBJECTIVE: This study was done (a) to evaluate the relationship between the plasma total homocysteine (tHcy) levels and coronary artery disease (CAD) in Asian Indians and (b) to see the relationship between tHcy and glucose intolerance. METHODS: Fasting concentrations of plasma tHcy was measured in 137 men, aged > or = 25 years who underwent coronary angiography while investigating for chest pain. Among them 71 had no CAD and 66 had CAD. Fasting plasma glucose (FPG) and glycosylated haemoglobin (HbA1c) were estimated. Total Hcy was measured using the Elisa method (Axis Biochemicals ASA-Oslo, Norway) in fasting EDTA plasma. RESULTS: The subjects with CAD were significantly older but had similar body mass index (BMI), waist-hip ratio (WHR), FPG and HbA1c values compared with the non-CAD subjects (P < 0.001). The median tHcy and the percentages of abnormal values were similar in non-CAD and CAD groups. No significant differences were seen in the four subgroups with respect to the mean tHcy or the percentage of abnormal values. The highest tHcy values were seen in the non-diabetic, non-CAD group (group 1--control). CONCLUSION: This preliminary data indicates that tHcy concentrations are not elevated in subjects with CAD and probably there is no association between total homocysteine and CAD in Indians. Homocysteine values were not influenced by the glucose tolerance status. Measurement of homocysteine concentrations may be more appropriate when the blood levels of vitamin B12 and folate are also measured.

Persistent microalbuminuria in type 1 diabetic subjects in South India.

AIM: There are only a few reports on the prevalence of microalbuminuria (MAU) in type 1 diabetic subjects in India. This study was done to assess the prevalence of MAU in South Indian diabetic subjects. MATERIAL AND METHODS: MAU was estimated by measuring albumin/creatinine ratio in an early morning urine sample on three occasions using immunoturbidimetry (> 30 microg albumin/mg creatinine) in South Indian patients. Kidney function tests were done in 95 type 1 DM, (M:F, 56:39). Persistent proteinuria was detected in 17 (17.9%) and they were excluded from the study. Further details were taken only in the remaining 78 subjects. Persistent MAU was seen in 22 (28.2%) and other 56 subjects had normoalbuminuria (NAU) (71.8%). RESULTS: There was no significant difference in the age, duration of DM and the average HbAlc between MAU and NAU. MAU developed at the age of > or = 20 years, even in subjects with onset of diabetes at a younger age. Diabetic retinopathy was present in 3 (13.6%) and ECG abnormalities were seen in one patient with MAU. None of the subjects in NAU group had these abnormalities. Prevalence of MAU increased with increasing duration of diabetes, MAU was present in 3 patients (10.3%) with duration of diabetes < or = 5 years, in five patients (23.8%) with duration of diabetes> 5 to < or = 10 years and in 14 (50%) patients with duration of diabetes > 10 years. Hypertension was present in 5 (22.7%) of MAU and only in one subject with NAU. CONCLUSION: It is observed that MAU occurs in type 1 diabetes after the age of 20 years and it is present in a large proportion of the study subjects.

Epidemiology of type 2 diabetes in Indians.

Prevalence of diabetes is increasing globally. India have the maximum increase during the last few years. Type 2 diabetes mellitus is the commonest form of diabetes. The prevalence of type 2 diabetes mellitus is 2.4% in rural population and 11.6% in urban population. Prevalence of impaired glucose tolerance is also high in the urban population. Subjects under 40 years of age have a higher prevalence of impaired glucose tolerance than diabetes. The important risk factors for high prevalence of diabetes include: High familial aggregation, obesity specially central one, insulin resistance and lifestyle changes due to rapid urbanisation. Diabetes Research Centre, Madras carried out many studies regarding the risk factors involved in causing type 2 diabetes mellitus. The results of these studies are mentioned here in this article to have a glimpse of overall risk factors involved in causation of diabetes mellitus.

Novel Sp family-like transcription factors are present in adult insect cells and are involved in transcription from the polyhedrin gene initiator promoter.

We earlier documented the involvement of a cellular factor, polyhedrin (polh) promoter-binding protein, in transcription from the Autographa californica nuclear polyhedrosis virus polh gene promoter. Sequences upstream of the polh promoter were found to influence polh promoter-driven transcription. Analysis of one such region, which could partially compensate for the mutated polh promoter and also activate transcription from the wild-type promoter, revealed a sequence (AcSp) containing a CACCC motif and a loose GC box resembling the binding motifs of the transcription factor Sp1. AcSp and the consensus Sp1 sequence (cSp) specifically bound factor(s) in HeLa and Spodoptera frugiperda (Sf9) insect cell nuclear extracts to generate identical binding patterns, indicating the similar nature of the factor(s) interacting with these sequences. The AcSp and cSp oligonucleotides enhanced in vivo expression of a polh promoter-driven luciferase gene. In vivo mopping of these factor(s) significantly reduced transcription from the polh promoter. Recombinant viruses carrying deletions in the upstream AcSp sequence confirmed the requirement of these factor(s) in polh promoter-driven transcription in the viral context. We demonstrate for the first time DNA-protein interactions involving novel members of the Sp family of proteins in adult insect cells and their involvement in transcription from the polh promoter.

Differentiation of embryonic mesenchymal cells to odontoblast-like cells by overexpression of dentin matrix protein 1.

Cells of the craniofacial skeleton are derived from a common mesenchymal progenitor. The regulatory factors that control their differentiation into various cell lineages are unknown. To investigate the biological function of dentin matrix protein 1 (DMP1), an extracellular matrix gene involved in calcified tissue formation, stable transgenic cell lines and adenovirally infected cells overexpressing DMP1 were generated. The findings in this paper demonstrate that overexpression of DMP1 in pluripotent and mesenchyme-derived cells such as C3H10T1/2, MC3T3-E1, and RPC-C2A can induce these cells to differentiate and form functional odontoblast-like cells. Functional differentiation of odontoblasts requires unique sets of genes being turned on and off in a growth- and differentiation-specific manner. The genes studied include transcription factors like core binding factor 1 (Cbfa1), bone morphogenetic protein 2 (BMP2), and BMP4; early markers for extracellular matrix deposition like alkaline phosphatase (ALP), osteopontin, osteonectin, and osteocalcin; and late markers like DMP2 and dentin sialoprotein (DSP) that are expressed by terminally differentiated odontoblasts and are responsible for the formation of tissue-specific dentin matrix. However, this differentiation pathway was limited to mesenchyme-derived cells only. Other cell lines tested by the adenoviral expression system failed to express odontoblast-phenotypic specific genes. An in vitro mineralized nodule formation assay demonstrated that overexpressed cells could differentiate and form a mineralized matrix. Furthermore, we also demonstrate that phosphorylation of Cbfa1 (osteoblast-specific transcription factor) was not required for the expression of odontoblast-specific genes, indicating the involvement of other unidentified odontoblast-specific transcription factors or coactivators. Cell lines that differentiate into odontoblast-like cells are useful tools for studying the mechanism involved in the terminal differentiation process of these postmitotic cells.

Risk variables for coronary artery disease in Asian Indians.

No large study from India has addressed the association of risk variables with coronary artery disease (CAD) in angiographically proved cases. In this study, we analyzed the association of anthropometric variables, lipoproteins, and coagulation parameters with CAD in those cases proved by coronary angiography. A cross-sectional study of 447 men > or = 25 years old, classified as with CAD or without CAD, was performed. Men treated with aspirin or lipid-lowering agents, and those with renal, hepatic, or thyroid diseases were excluded. Associations of these variables with CAD were evaluated by univariate and multiple logistic regression analyses. The effect of diabetes on the CAD profile was also analyzed. Prevalences of diabetes and hypertension were significantly higher among those with CAD (p <0.001 for both). Lipid profile abnormalities, except lipoprotein (Lp(a)), were associated with CAD. Antibodies to oxidized low-density lipoprotein was higher in patients with CAD. Fibrinogen levels were higher in CAD, but plasminogen activator inhibitor-1 did not show an association with CAD. In the multiple logistic regression analysis, age, body mass index, very-low-density lipoprotein cholesterol, total to high-density lipoprotein cholesterol ratio, and fibrinogen showed significant independent association with CAD. Several lipid abnormalities were associated with CAD in Asian Indians, but no significant association was seen with Lp(a) levels.

Nitric oxide protects the intestine from the damage induced by laparotomy and gut manipulation.

BACKGROUND: The intestine is highly susceptible to free radical-induced damage, and our earlier work has shown that surgical stress induces the generation of oxygen free radicals in enterocytes, resulting in intestinal damage along with ultrastructural changes. Since nitric oxide (NO) is an important mediator of gastrointestinal function, this study looked at the effect of NO on surgical stress-induced intestinal alterations. MATERIALS AND METHODS: Control rats and rats pretreated with the NO donor l-arginine were subjected to surgical stress by opening the abdominal wall and handling the intestine as done during laparotomy. Enterocytes were isolated and homogenate prepared, and the protection offered by l-arginine against damage due to surgical stress was determined and compared with normal controls. Protection to structural as well as functional aspects of the intestine was also examined. RESULTS: Intestinal manipulation affected intestinal structure as assessed by electron microscopy. Functional impairment of the enterocyte was also evident, with increased xanthine oxidase activity resulting in production of superoxide anion. This impairment is more dramatic in the crypt cells. Increased protease activity was also seen following laparotomy and handling. Pretreatment with the NO synthase substrate l-arginine prevented these damaging effects. Arginine protection was abolished in the presence of the NO synthase inhibitor NG-nitro-l-arginine methyl ester, indicating the role of NO. CONCLUSION: Stress in the small intestine due to any surgery can affect enterocyte structure and function. These damaging effects can be prevented by NO, an important modulator of cellular function.

Intestinal mitochondrial dysfunction in surgical stress.

BACKGROUND: Surgical stress is associated with altered intestinal function. Our earlier study using a rat model indicated that oxidative stress plays an important role in this process. Since mitochondria are crucial to cellular function and survival and are both a target as well as a source of reactive oxygen species, the present study looks at the changes in enterocyte mitochondria during surgical stress. METHODS: Surgical stress was induced by opening the abdominal wall and handling the intestine as done during laparotomy. Mitochondria were prepared from the isolated enterocytes at different time periods after surgical stress. The effect of surgical stress on enterocyte mitochondrial ultrastructure, respiration, anti-oxidant enzyme activity, thiol redox status, calcium flux, permeability, and matrix enzymes was then studied. RESULTS: Surgical stress resulted in alterations in mitochondrial respiration and thiol redox status. It was also associated with altered mitochondrial matrix enzyme activity, decreased superoxide dismutase activity, induction of mitochondrial permeability transition, and swelling, as well as impairment of mitochondrial calcium flux. These alterations were seen at a maximum of 60 min following surgical stress and were reversed by 24 h. CONCLUSIONS: Laparotomy and mild intestinal handling itself results in enterocyte mitochondrial damage. Since mitochondria are important cellular organelles, this damage can probably lead to compromised intestinal function.

High prevalence of diabetes and impaired glucose tolerance in India: National Urban Diabetes Survey.

AIMS/HYPOTHESIS: There has been no reported national survey of diabetes in India in the last three decades, although several regional studies show a rising prevalence of diabetes. The aim of this study was to assess the prevalence of diabetes and impaired glucose tolerance in six major cities, covering all the regions of the country. METHODS: Using a stratified random sampling method, 11216 subjects (5288 men; 5928 women) aged 20 years or above, representative of all socio-economic strata, were tested by OGTT. Demographic, anthropometric, educational and social details were recorded using a standard proforma. Physical activity was categorised using a scoring system. Body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. Glucose tolerance was classified using the 2-h values (WHO criteria). Prevalence estimations were made taking into account the stratified sampling procedure. Group comparisons were done by t-test or analysis of variance or Z-test as relevant. Univariate and multiple logistic regression analyses were used to study the association of variables with diabetes and impaired glucose tolerance. RESULTS: Age standardised prevalences of diabetes and impaired glucose tolerance were 12.1% and 14.0% respectively, with no gender difference. Diabetes and impaired glucose tolerance showed increasing trend with age. Subjects under 40 years of age had a higher prevalence of impaired glucose tolerance than diabetes (12.8% vs 4.6%, p < 0.0001). Diabetes showed a positive and independent association with age, BMI, WHR, family history of diabetes, monthly income and sedentary physical activity. Age, BMI and family history of diabetes showed associations with impaired glucose tolerance. CONCLUSIONS/INTERPRETATION: This national study shows that the prevalence of diabetes is high in urban India. There is a large pool of subjects with impaired glucose tolerance at a high risk of conversion to diabetes.

A comparative study of sialic acid-rich proteins in rat bone and dentin.

Four sialic acid-rich (SA-rich) proteins found in bone and dentin, osteopontin (OPN), bone sialoprotein (BSP), bone acidic glycoprotein-75 (BAG-75), and dentin matrix protein 1 (DMP1), share some common features. We used SDS-PAGE and Western immunoblots to analyze and compare SA-rich proteins in bone and dentin extracts from rats with a single chromatographic procedure. OPN was detected in dentin extracts, with a relative level less than one-seventieth of that in bone. Both bone and dentin BSP demonstrated an extremely broad distribution pattern, probably due to a high degree of heterogeneity in post-translational modifications. BAG-75 in both bone and dentin was detected as an 83 kDa band, dramatically distinct from that of DMPI. Using a polyclonal antibody raised against a purified bone 57 kDa protein (a portion of DMPI), we detected 150 kDa protein bands in bone fraction; the same bands were recognized by antirecombinant rat DMPI antibody. Bands from dentin migrating at about 150 kDa in earlier fractions and progressing to 200 kDa in later fractions showed a clear immunoreactivity to the anti-57 kDa antibody. We conclude that the majority of DMPI in rat bone is processed into fragments, whereas that in dentin remains intact.

Intestinal dysfunction in liver cirrhosis: Its role in spontaneous bacterial peritonitis.

Spontaneous bacterial peritonitis is a common illness in patients with cirrhosis and ascites that occurs without any apparent focus of infection. Bacterial translocation plays an important role in spontaneous bacterial peritonitis and it is evident from a variety of studies that the gut is a major source of this bacteria. Gut motility alterations, along with bacterial overgrowth and changes in intestinal permeability, probably play a role in this bacterial translocation. The present review looks at the role of the intestine in spontaneous bacterial peritonitis induced by liver cirrhosis and the factors influencing bacterial translocation in this disease.

Association of proinsulin and insulin resistance with coronary artery disease in non-diabetic south Indian men.

AIMS: To evaluate the association of plasma proinsulin and insulin resistance (IR) with coronary artery disease (CAD) in non-diabetic subjects. METHODS: In this case control study, 41 normoglycaemic men with angiographic evidence of CAD were compared with 41 control men matched for age and glycaemia and with no history or evidence of cardiac diseases. Estimations of plasma glucose, lipids, fasting plasma specific insulin (SI) and proinsulin (PI) were performed. IR was calculated by the homeostasis model assessment (HOMA) method. Multiple logistic regression analysis was performed to test the association of the variables with the prevalence of CAD. RESULTS: Subjects with CAD had a higher body mass index (BMI) (25.4 +/- 4.3 vs. 22.9 +/- 3.2 kg/m2, P = 0.003) and waist to hip ratio (WHR) (0.95 +/- 0.05 vs. 0.89 +/- 0.09, P = 0.001) and a lower high-density lipoprotein (HDL) cholesterol level (0.97 +/- 0.2 vs. 1.1 +/- 0.2 mmol/l, P = 0.002). They also had higher mean SI values (107.5 vs. 62.3 pmol/l, P = 0.002), PI values (19.3 vs. 5.7 pmol/l, P < 0.0001), PI/SI ratios (21.4 vs. 10.3, P < 0.0001) and HOMA IR (4.2 vs. 2.4, P = 0.004) compared with non-CAD subjects. These variables were associated with CAD in the unadjusted multiple regression analysis. In the multiple regression with the forward entry of the variables, WHR and PI only showed independent association with CAD. CONCLUSIONS: Subjects with CAD had higher levels of obesity and WHR. CAD showed an association with low HDL cholesterol, circulating PI, PI/SI ratios and IR.
