Polymorphisms of the gene encoding adiponectin and glycaemic outcome of Chinese subjects with impaired glucose tolerance: a 5-year follow-up study.

AIMS/HYPOTHESIS: Polymorphisms of the gene encoding adiponectin (ADIPOQ) have previously been associated with type 2 diabetes in Europid and Japanese subjects, but not in Pima Indians. The aim of this study was to determine the contribution made by ADIPOQ gene variants to glycaemic status in southern Chinese individuals. SUBJECTS AND METHODS: Sixty unrelated subjects were screened for single-nucleotide polymorphisms (SNPs) in the ADIPOQ gene by direct sequencing. The association of tagging SNPs with the outcome of glycaemic status in 262 subjects with impaired glucose tolerance (IGT) was examined in a 5-year prospective study. RESULTS: We identified 15 polymorphisms in the ADIPOQ gene, ten of them constituting the tagging SNPs. At 5 years, 39.7% of the subjects with IGT had regressed to NGT, 41.2% had persistent IGT or impaired fasting glucose and 19.1% had developed diabetes. Only the T45G polymorphism was associated with persistent hyperglycaemia at 5 years (p=0.001). Haplotypes formed by the addition of other SNPs, as haplotype blocks or pairs, did not confer greater association than T45G alone. On logistic regression analysis, T45G independently predicted persistent hyperglycaemia at 5 years (OR=2.25, 95% CI 1.29-3.95, G carriers vs TT; p=0.005). It also predicted persistent hyperglycaemia in a nested case-control study involving 158 sex- and age-matched controls with persistent NGT (p=0.012, adjusted for BMI), and that of diabetes or glycaemia progression (p<0.05) in a meta-analysis that also included two published studies in Europid subjects. CONCLUSIONS/INTERPRETATION: Our findings support a significant role of this common ADIPOQ gene polymorphism in predicting glycaemic status in southern Chinese people.

Determinants of normoglycemia and contribution to cardiovascular risk factors in a Chinese population: the Hong Kong Cardiovascular Risk Factor Study.

BACKGROUND: Glucose intolerance is clearly associated with increasing risk of cardiovascular disease, but the association among increasing glycemia and cardiovascular risk factors, angina and coronary heart disease in normoglycemic subjects is less clear, particularly in Chinese. METHODS: A total of 2763 subjects were recruited and the prevalence of glucose intolerance investigated, using fasting or 2-h 75-g oral glucose tolerance test (OGTT), glucose levels. Subjects normoglycemic by both criteria were selected and the relationship between glycemia and cardiovascular risk factors investigated using analysis of variance and stepwise multiple linear regression analyses. RESULTS: 1931 (69.9%) subjects were normoglycemic by both tests. After adjustment for age and gender, quartiles of fasting and post-load glucose levels showed a clear positive relationship with cardiovascular risk factors, including obesity, blood pressure and lipid levels (p<0.001 for all). Additionally, other measures of glycemia and insulin resistance also dose-dependently increased with increasing fasting and post-load glucose levels (p<0.001 for all). Stepwise multiple regression showed that in females, age (standardised regression coefficient beta (beta)=0.23, p<0.001), insulin (beta=0.17, p<0.001), waist circumference (beta=0.11, p=0.007) were independently associated with fasting glucose levels; and body mass index (beta=0.17, p<0.001), age (beta=0.15, p<0.001) and triglycerides (beta=0.15, p<0.001) were independently associated with post-load glucose levels. In males, age (beta=0.19, p<0.001) and insulin (beta=0.18, p<0.001) were independently associated with fasting glucose levels; and waist circumference (beta=0.17, p<0.001), triglycerides (beta=0.16, p<0.001) and insulin (beta=0.12, p=0.001) were independently associated with post-load glucose levels.

Association of hypertension with single nucleotide polymorphisms in the quantitative trait locus for abdominal obesity-metabolic syndrome on chromosome 17.

Genome scan in Chinese revealed an association of blood pressure with the microsatellite marker D17S1303, which lies in a quantitative trait locus for the abdominal obesity-metabolic syndrome (AOMS2) at 17p12 on chromosome 17. We previously reported that D17S1303 was associated with hypertension and obesity. Therefore, we studied 10 single nucleotide polymorphisms (SNP) within 3 kb of D17S1303. One hundred and eighty hypertensive subjects (91 men, 89 women, age 53+/-12 years) and 180 normotensive matched controls (91 men, 89 women, age 52+/-11) were genotyped using the Sequenom genotyping platform. Allelic frequencies in these Chinese subjects differed from those reported for Caucasians. Three SNPs (rs11656507, rs1357926, rs852319) were homozygous in our subjects. The genotype frequencies of rs852320, rs852321 and rs852322 did not differ between hypertensive and normotensive subjects. However, there were significant differences for rs1525402 (P=0.048), rs2692343 (P=0.022), rs2692344 (P=0.017) and rs2321313 (P=0.028). A four-locus haplotype comprising G at rs1525402, C at rs2692343, C at rs2692344 and G at rs2321313 was associated with lower systolic blood pressure (P=0.023) and normotension (P=0.048). Our results provide further evidence that there is a gene, as yet unidentified, influencing blood pressure in the vicinity of D17S1303 in a quantitative trait locus for abdominal obesity-metabolic syndrome at 17p12.

Fat-derived hormone adiponectin combined with FTY720 significantly improves small-for-size fatty liver graft survival.

Owing to the discrepancy between organ donation and the demand for liver transplantation, expanding the liver donor pool is of vital importance. However, marginal liver grafts, such as small-for-size and/or fatty grafts, were associated with primary graft nonfunction or poor function. Therefore, novel combination therapies to rescue small-for-size fatty liver grafts should be investigated. In this study, we applied a combination therapy using a fat-derived hormone adiponectin (anti-steatosis) plus immunomodulator FTY720 (anti-inflammatory) in a rat liver transplantation model using small-for-size fatty liver grafts, and investigated the underlying protective mechanism such as anti-steatosis, intra-graft energy metabolism, hepatic microcirculatory changes, cell signaling cascades for survival, apoptosis and inflammation. The current study demonstrated that even a single treatment of adiponectin or FTY720 improved the 7-day graft survival from 0% to 62.5% (p = 0.001). The combination therapy significantly increased the 7-day graft survival rate to 100% by remarkable attenuation of graft steatosis and acute phase inflammatory response, significant activation of cell survival Akt pathway and maintenance of intra-graft adenosine triphosphate metabolism and improvement of hepatic microcirculation. In conclusion, the fat-derived hormone adiponectin combined with FTY720 might be a novel combination drug therapy for prevention of small-for-size fatty liver graft injury.

Randomised controlled trial of qigong in the treatment of mild essential hypertension.

Exercise and relaxation decrease blood pressure. Qigong is a traditional Chinese exercise consisting of breathing and gentle movements. We conducted a randomised controlled trial to study the effect of Guolin qigong on blood pressure. In all, 88 patients with mild essential hypertension were recruited from the community and randomised to Goulin qigong or conventional exercise for 16 weeks. The main outcome measurements were blood pressure, health status (SF-36 scores), Beck Anxiety and Depression Inventory scores. In the qigong group, blood pressure decreased significantly from 146.3+/-7.8/93.0+/-4.1 mmHg at baseline to 135.5+/-10.0/87.1+/-7.7 mmHg at week 16. In the exercise group, blood pressure also decreased significantly from 140.9+/-10.9/93.1+/-3.5 mmHg to 129.7+/-11.1/86.0+/-7.0 mmHg. Heart rate, weight, BMI, waist circumference, total cholesterol, renin and 24 h urinary albumin excretion significantly decreased in both groups after 16 weeks. General health, bodily pain, social functioning and depression also improved in both groups. No significant differences between qigong and conventional exercise were found. In conclusion, Guolin qigong and conventional exercise have similar effects on blood pressure in patients with mild hypertension. While no additional benefits were identified, it is nevertheless an alternative to conventional exercise in the nondrug treatment of hypertension.

Resection of phaeochromocytoma extending into the right atrium in a patient with multiple endocrine neoplasia type 2A.

We report the first case of successful surgical resection of a malignant phaeochromocytoma with tumour extension into vena cava and right atrium in a patient with multiple endocrine neoplasia type 2A. A 21-year-old woman with genetic confirmation of multiple endocrine neoplasia type 2A syndrome was diagnosed with a very rare case of malignant phaeochromocytoma with tumour thrombus extension into vena cava and right atrium causing Budd-Chiari syndrome. It posed a challenge to the surgeons with regard to complete tumour resection and vascular control. Reviewing the limited literature, surgical resection by means of cardiopulmonary bypass with hypothermic circulatory arrest has been reported with success in phaeochromocytoma with advance vascular involvement. Adopting this approach, adrenalectomy with complete thrombus excision by inferior vena cava exploration and right atriotomy were performed successfully by a multidisciplinary team.

Hypoadiponectinemia is associated with impaired endothelium-dependent vasodilation.

Adiponectin may have an antiatherogenic effect by reducing endothelial activation. We hypothesized that plasma adiponectin levels were correlated with endothelial function. Plasma adiponectin level was determined by an in-house RIA assay using a rabbit polyclonal antibody in 73 type 2 diabetic patients and 73 controls. Endothelium-dependent and independent vasodilation of the brachial artery was measured by high-resolution vascular ultrasound. Plasma adiponectin level was lower in diabetic patients than in controls (4.73 +/- 1.96 vs. 7.69 +/- 2.80 microg/ml, respectively; P < 0.001), and they also had impaired endothelium-dependent (5.6 +/- 3.6 vs. 8.6 +/- 4.5%, respectively; P < 0.001) and -independent vasodilation (13.3 +/- 4.9 vs. 16.5 +/- 5.6%, respectively; P < 0.001). Plasma adiponectin correlated with endothelium-dependent vasodilation in controls (P = 0.02) and diabetic patients (P = 0.04). On general linear-model univariate analysis, brachial artery diameter, the presence of diabetes, plasma adiponectin, and high-density lipoprotein were significant independent determinants of endothelium-dependent vasodilation. In vitro experiments showed that endothelial cells expressed adiponectin receptors, and adiponectin increased nitric oxide production in human aortic endothelial cells. In conclusion, low plasma adiponectin level is associated with impaired endothelium-dependent vasodilation, and the association is independent of diabetes mellitus. Adiponectin may act as a link between adipose tissue and the vasculature.

Multiple endocrine neoplasia type 2B in a Chinese patient.

Multiple endocrine neoplasia type 2B syndrome is rarely reported in Chinese patients. A 25-year-old Chinese male presented with full-blown clinical features of this syndrome, including bilateral phaeochromocytomas, medullary thyroid carcinoma, and characteristic phenotypic features. One-stage surgical treatment was performed and subsequent genetic analysis confirmed a point mutation at codon 918 in exon 16 of the RET proto-oncogene. The mutation was arising de novo as there was no corresponding mutation found in both his parents or younger sister. Data published to date suggest there is no difference in the genetic and pathophysiologic basis, nor clinical characteristics of multiple endocrine neoplasia type 2B in Chinese patients. As the disease can be lethal, early diagnosis by prompt recognition of the characteristic phenotypic features followed by surgical treatment should improve the outcome. Family screening is essential to identify at-risk family members for prophylactic treatment.

Effect of the microsomal triglyceride transfer protein -493 G/T polymorphism and type 2 diabetes mellitus on LDL subfractions.

Genetic variation in the microsomal triglyceride transfer protein (MTP) affects the secretion pattern and plasma concentration of apolipoprotein (aopB)-containing lipoproteins and a common functional -493 G/T polymorphism has been reported to influence plasma lipids levels. Recent data suggest that carriers of the T allele might be more sensitive to detrimental factors such as features of the insulin resistance syndrome. Since type 2 diabetes is associated with obesity and insulin resistance, the present study investigated the effect of this polymorphism on plasma lipids, apoB and LDL subfractions in 281 Chinese type 2 diabetic subjects and 364 non-diabetic controls. The frequency of the rare T allele was 0.162 and 0.126 in subjects with and without diabetes respectively. There were no differences in the effect of the polymorphism on plasma lipids and apoB in the two groups. However, the TT genotype was associated with a higher concentration of small dense LDL-III than the GT or GG variants in the diabetic subjects (P=0.01) whereas no such effect was observed in the controls. In the diabetic patients, age, plasma triglyceride and the MTP genotype were independent determinants of LDL-III concentrations in linear regression analysis (R(2)=10%, P=0.04) whereas in the controls, only plasma triglyceride and age were important determinants (R(2)=15%, P=0.01). In conclusion, the -493 G/T polymorphism only has a minor effect on LDL subfraction pattern in Chinese and the effect is only apparent in the presence of type 2 diabetes.

Diet and glucose tolerance in a Chinese population.

BACKGROUND: Associations between dietary factors and glucose tolerance observed in Caucasian populations may not be applicable to Chinese populations, since the traditional Chinese diet contains plentiful vegetables and is rice-based (which has a lower glycemic index than potatoes). To address this question, the dietary patterns in 988 Hong Kong Chinese subjects with normal and impaired glucose tolerance, and diabetes, were examined in a cross sectional survey to determine if there is any association between diet and glucose tolerance. METHOD: A stratified random population sample of 988 subjects (488 male, 500 female) was recruited. A food frequency questionnaire was used to determine dietary intake, and glucose tolerance was examined using the glucose tolerance test and the WHO criteria used to classify subjects into the three glucose tolerance categories. RESULTS: Using the standardized world population of Segi, the prevalence rate for DM was 6.6% for men and 5.7% for women; and for IGT 10.3% for men and 15.4% for women aged 30-64 y. Abnormal glucose tolerance is associated with female gender, older age, lower educational attainment and higher body mass index (BMI). No clear pattern of association with dietary factors was observed after adjusting for confounding factors. However, if subjects with BMI>or=25 kg/m(2) were excluded, an increase in mean consumption of rice/noodles/pasta per week was observed in the DM group, after adjusting for total energy intake and other confounding factors. No association between dietary variety, which has been linked with body fatness, and glucose tolerance, was observed. CONCLUSION: Dietary habit may not be a strong risk factor for the development of glucose intolerance in Chinese populations, given the favorable features of the Chinese diet. The high consumption of rice in the DM subjects who are of normal BMI suggests that further studies examining glycemic indices of Chinese food items may be beneficial. Obesity still remains the most important predisposing factor.

Multiple endocrine neoplasia type 1 (MEN1): genetic and clinical analysis in the Southern Chinese.

OBJECTIVE: Multiple endocrine neoplasia type 1 (MEN1) is characterized by a triad of neoplasia affecting the parathyroid glands, enteropancreatic endocrine tissue and the anterior pituitary gland. DESIGN: In order to define the prevalence of MEN1 germ-line mutations in Southern Chinese patients with MEN1 syndrome, we performed direct sequencing of the entire open reading frame of the MEN1 gene for 12 index patients and their first-degree relatives. RESULTS: Six patients had familial MEN1 syndrome and six had apparently sporadic disease. Nine different germ-line mutations at the MEN1 gene were identified, including three novel mutations [248-249delTT in exon 2, K559X(AAG --> TAG) in exon 10 and IVS 2nt + 2(G --> T) in intron 2]. All patients with familial MEN1 syndrome were heterozygous carriers of a germ-line mutation and MEN1-related disorders were only evident in their first-degree relatives who also carried the mutation. All patients with an enteropancreatic lesion were mutation carriers and the absence of mutation in three apparently sporadic MEN1 patients with only hyperparathyroidism and pituitary microadenoma might represent the presence of MEN1 phenocopy. CONCLUSIONS: The finding of MEN1 germ-line mutation in all patients with familial MEN1 syndrome suggests that genetic screening should be useful in our population to identify affected individuals within a kindred and allow early detection of MEN1-related tumours.

Effects of treatment with Sandostatin LAR on small dense LDL and remnant-like lipoproteins in patients with acromegaly.

OBJECTIVE: Acromegalic patients have been shown to have an increase in the concentrations of small dense low-density lipoprotein (LDL) and remnant-like lipoprotein particles (RLP). These lipoproteins are atherogenic and may contribute to the cardiovascular risk of these patients. The aim of this study was to determine whether treatment of acromegaly using Sandostatin LAR could lower these atherogenic lipoproteins. METHODS: Fourteen patients with active acromegaly were recruited and Sandostatin LAR, a long-acting somatostatin analogue, was given every 4 weeks by intramuscular injection for 6 months. Fasting lipids, lipoproteins, lipolytic enzymes were determined at baseline, 12 and 24 weeks after treatment. Small dense LDL was measured using density gradient ultracentrifugation and RLP-cholesterol (RLP-C) by an immunoseparation assay. RESULTS: There was already a marked reduction in GH and IGF-1 by week 8 and, in all subjects, IGF-1 levels within their respective age-specific normal range were achieved. At week 12, plasma triglyceride significantly decreased (P < 0.01) and both HDL2 (P < 0.01) and HDL3 (P < 0.01) subfractions increased. A reduction was seen in small dense LDL concentration (P < 0.05) and RLP-C (P < 0.05). Lipoprotein lipase (LPL) activity increased (P < 0.01) and the magnitude of the increase in LPL activity correlated with the increase in HDL at 3 months (r = 0.55, P < 0.05) but not with the changes in plasma triglyceride, small dense LDL or RLP-C. The improvement in plasma lipids and lipoproteins persisted until the end of the study. CONCLUSION: Sandostatin LAR is effective in the treatment of acromegaly and is associated with favourable changes in plasma lipids and a reduction in small dense LDL and RLP-C.

Mutations in the hepatocyte nuclear factor-1alpha gene in Chinese MODY families: prevalence and functional analysis.

AIMS/HYPOTHESIS: Maturity-onset diabetes of the young is an autosomal dominant form of diabetes characterised by an early age of onset (usually <25 years). We investigated the prevalence and trans-activating activity of hepatocyte nuclear factor (HNF) -1 alpha mutations in southern Chinese families with MODY. METHODS: We screened for mutations in the HNF-1 alpha gene in 50 unrelated southern Chinese families, which fulfilled the minimum criteria for MODY. Functional properties of the mutant proteins were investigated using site-directed mutagenesis and luciferase reporter assay. RESULTS: Five of the 50 (10%) families were found to have mutations in the coding region, including a new nonsense mutation Q176X and four reported mutations (frameshift mutation P379fsdelCT, nonsense mutation R171X, missense mutations G20R and P112L). These mutations had decreased trans-activating activity on the human insulin gene promoter. We also detected a new intronic sequence variation IVS7nt-6 G-->A, which co-segregated with diabetes. The intronic variation creates a potential splice acceptor site and might alter the splicing of the HNF-1 alpha mRNA. CONCLUSION/INTERPRETATION: Mutations in the HNF-1 alpha gene seem to be an important cause of MODY in southern Chinese. The mutations could affect normal islet function by altering the expression of target genes.

Hyperhomocysteinemia and impaired vasomotor function in type 2 diabetes mellitus.

BACKGROUND: Hyperhomocysteinemia has been shown to adversely affect vascular function. The aim of this study was to determine whether hyperhomocysteinemia was independently associated with changes in endothelium-dependent and -independent vasomotor functions in patients with type 2 diabetes mellitus. MATERIALS AND METHODS: Fasting homocysteine (tHcy) was measured in 123 patients with type 2 diabetes and in 61 nondiabetic controls. Endothelium-dependent and -independent vasodilation was measured using high-resolution vascular ultrasound. RESULTS: Plasma tHcy concentration was increased in the diabetic patients (11.1 +/- 3.7 micromol L(-1) vs. 9.8 +/- 2.9, P < 0.05). The prevalence of hyperhomocysteinemia (defined as tHcy > 15 micromol L(-1)) was higher in the diabetic patients (P < 0.05). Within group comparisons showed that both the abnormalities in endothelium-dependent and -independent vasodilation were significantly more severe in diabetic patients with tHcy 10-15 (P < 0.05) and tHcy > 15 micromol L(-1) (P < 0.05) than in those patients with tHcy < 10 micromol L(-1). When compared with nondiabetic controls matched for tHcy levels, impairment of endothelium-dependent and -independent vasodilation were already evident, even in patients with normal tHcy levels (P < 0.01). Despite significant univariate relationships between tHcy and endothelium-dependent (r = -0.24, P < 0.01) and -independent vasodilation (r = -0.33, P < 0.01) in patients with diabetes, only the relationship between tHcy and endothelium-independent vasodilation remained significant after adjusting for other cardiovascular risk factors in multiple regression analysis. CONCLUSIONS: Impairment of endothelium-dependent and -independent vasodilation was already present in diabetic patients with normal tHcy levels, and these abnormalities became more severe with increasing tHcy levels. Only the association between tHcy and endothelium-independent vasodilation was free of other cardiovascular risk factors.

Diabetic nephropathy is associated with the 5'-end dinucleotide repeat polymorphism of the aldose reductase gene in Chinese subjects with Type 2 diabetes.

AIMS: We investigated whether the promoter dinucleotide repeat polymorphism of the aldose reductase gene (5'-ALR2), implicated in the development of nephropathy in Type 1 diabetes, was associated with diabetic nephropathy in Type 2 diabetes. METHODS: In 265 Southern Chinese with Type 2 diabetes the 5' -ALR2 polymorphism was identified in genomic DNA using polymerase chain reaction and automated fluorescent scanning. They were classified as normoalbuminuric (n = 128), microalbuminuric (n = 85) or albuminuric (n = 52) according to the mean albumin excretion rate of two 12-h overnight collections. RESULTS: The 5' -ALR2 allele and genotype distributions differed significantly among the three groups of patients (P < 0.003 and P < 0.01, respectively). Normoalbuminuric patients had the lowest Z - 2 allele frequency: 17.6% vs. 28.2% and 23.1% for microalbuminuric and albuminuric patients, respectively, and the highest Z + 2 allele frequency: 36.7% vs. 21.2% and 23.1% in microalbuminuric and albuminuric patients, respectively. They also had the lowest Z - 2/X genotype frequency (X = any allele other than Z + 2): 18.8% vs. 36.5% in microalbuminuric (P < 0.01) and 38.5% in albuminuric patients (P < 0.02), respectively, but the highest Z + 2/Y genotype frequency (Y = any allele other than Z - 2): 50.7% vs. 27.0% and 34.6% in microalbuminuric (P < 0.001) and albuminuric patients, respectively. In a multiple logistic regression model, the Z - 2/X genotype (odds ratio 3.10; P < 0.025) was an independent risk factor of diabetic nephropathy, microalbuminuria or albuminuria, together with age, mean arterial pressure and body mass index. CONCLUSIONS: The 5' -ALR2 dinucleotide repeat polymorphism is associated with the development of diabetic nephropathy in Southern Chinese with Type 2 diabetes.

Acute effect of orlistat on post-prandial lipaemia and free fatty acids in overweight patients with Type 2 diabetes mellitus.

AIMS: Post-prandial lipaemia is prolonged and exaggerated in patients with Type 2 diabetes mellitus, with an accumulation of atherogenic triglyceride-rich lipoprotein remnants. We postulate that orlistat, a gastrointestinal lipase inhibitor, may cause changes in post-prandial lipoprotein metabolism by reducing dietary triglyceride absorption. METHODS: The acute effect of a single dose of 120 mg orlistat on post-prandial glucose, lipids, remnant lipoproteins and free fatty acids (FFA) was evaluated in a randomized, double-blind, placebo-controlled cross-over study of 63 overweight patients with Type 2 diabetes mellitus (body mass index 30.4 +/- 3.8 kg/m2). Either a single dose of orlistat or placebo was given before a standard mixed meal containing 70 g of fat and plasma triglyceride (TG), remnant-like particles cholesterol (RLP-C) and FFA were sampled at 2-h intervals for 8 h. RLP-C was measured by an immunoseparation assay and FFA by an enzymatic colorimetric method. RESULTS: The concentrations of plasma TG (P < 0.0001), RLP-C (P = 0.003), and FFA (P < 0.0001) were significantly lower at 2 h after orlistat compared with placebo. Both plasma RLP-C (P = 0.04) and FFA (P < 0.0001) remained lower after orlistat than placebo at 4 h. The incremental area under the curve (iAUC) above baseline fasting level for both TG and RLP-C was significantly more reduced after orlistat than placebo (iAUC-TG 5.8 (3.7-8.2) mmol/l x h-1 vs. 5.7 (4.1-10.9), respectively, P = 0.04; iAUC-RLP-C: 0.53 (0.23-1.04) mmol/l x h-1 vs. 0.56 (0.35-1.40), respectively, P = 0.02). The test meal was well tolerated by all subjects, with only three subjects reporting faecal urgency after orlistat. CONCLUSIONS: Orlistat has a beneficial effect on post-prandial lipaemia in overweight Type 2 diabetic patients and lowers plasma TG, RLP-C and FFA in the early post-prandial period.
