Metbods: Plasma obese protein level was measured by radioimmunoassay in 21 normal subjects, 24 adult obese patients and 20 patients with NIDDM. Results: The levels of the plasma obese protein in NIDDM patients (81. 0±17. 5 pg/ml) were very significantly lower than those in normal subjects (194. 3±17. 7 pg/ml) and obese patients (109.1±16. 4 pg/ml ) (P<0.01). The levels of the plasma obese protein in non-obese NIDDM patients were very significantly lower than those in non-obese normal subjects (P<0.01), and the levels of the plasma obese protein in obese NIDDM patients were very significantly lower than those in obese patients (P<0. 01). The leve1s of the plasma obese protein in NIDDM patients were significantly correlated with polyphagia (P<0.05), but not correlated with the body weight indexes after strict dieting, and the plasma levels of cholesterol, triglyceride, fasting glucose, hemoglobiti A, and the insulin levels during glucose tolerance test (P>0.05). Couclusion: Low plasma level of obese protein is one of the important factors contributing to obesity,and plasma obese protein may be closely related to the generation of NIDDM.展开更多

NAFLD incorporates histologically and clinically different nonalcoholic entities; fatty liver(NAFL, steatosis hepatis)and steatohepatitis(NASH-characterised by hepatocyte ballooning and lobular inflammation ± fibrosis) might progress to cirrhosis and rarely to hepatocellular cancer.NAFL increasingly affects children(paediatric prevalence is 4.2%-9.6%). Type 2 diabetes mellitus(T2DM),insulin resistance(IR), obesity, metabolic syndrome and NAFLD are particularly closely related. Increased hepatic lipid storage is an early abnormality in insulin resistant women with a history of gestational diabetes mellitus. The accumulation of triacylglycerols in hepatocytes is predominantly derived from the plasma nonesterified fatty acid pool supplied largely by the adipose tissue. A few NAFLD susceptibility gene variants are associated with progressive liver disease, IR, T2 DM and a higher risk for hepatocellular carcinoma. Although not approved, pharmacological approaches might be considered in NASH patients.展开更多

Although DM with proteinuria is the ultimate result of diabetic nephropathy (DN), a wide spectrum of non-diabetic renal diseases (NDRD) can occur in such patients. Objective: To observe the frequency and histological pattern of NDRD in diabetic patients with proteinuria and to explore their association with clinical and laboratory parameters. Methods: This cross-sectional study was conducted in the Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from April 2016 to September 2017. In this study a total of 38 cases of DM with proteinuria (>1 gm/24-hour) were selected purposively. Renal biopsy was done in all patients. Based on histological findings they were categorized into two groups;Group 1 with NDRD and Group II with DN. Their clinical and laboratory parameters were analyzed and compared. Results: Among the total study subjects, 21 (55.3%) were male and 17 (44.7%) were female, mean (±SD) age 43.45 ± 9.99 years in the NDRD group and 41.57 ± 9.50 years in the DN group. Thirty one cases (81.6%) out of thirty eight had NDRD and seven (18.4%) cases had isolated DN;therefore more than two third cases had NDRD. Duration of DM was found to be significantly shorter (p = 0.004) in the NDRD group. Diabetic retinopathy was present in 12.9% cases in NDRD group vs. 57.1% cases in DN group (p = 0.025). Frequency of microscopic hematuria was significantly higher (90.3%) in NDRD patients (p = 0.002). Conclusion: The frequency of NDRD in type 2 diabetic patients other than diabetic nephropathy is relatively high. Membrano proliferative glomeru-lonephritis and membranous nephropathy are more common in NDRD. Absence of diabetic retinopathy, presence of hematuria and shorter duration of DM are markers associated with NDRD in type 2 DM, which are important indicators for renal biopsy in diabetic patients with proteinuria.展开更多

Outcomes are complicated by immunosuppressive drug toxicity. Xenotransplantation is a strategy to overcome supply problems. Implantation of tissue obtained early during embryogenesis is a way to reduce transplant immunogenicity. Pig insulin is biologically active in humans. In that regard the pig is an appropriate xenogeneic organ donor. Insulin-producing cells originating from embryonic pig pancreas obtained very early following pancreatic primordium formation [embryonic day 28 (E28)] engraft long-term in rhesus macaques. Endocrine cells originating from embryonic pig pancreas transplanted in host mesentery migrate to mesenteric lymph nodes, engraft, differentiate and improve glucose tolerance in rhesus macaques without the need for immune suppression. Transplantation of embryonic pig pancreas is a novel approach towards beta cell replacement therapy that could be applicable to humans.展开更多

Glucose,urea nitrogen (BUN), creatinine (Cr), urine acid (UA), N-acetyl-β2-D-glucosaminidase(NAG), β2-microglobulin(β2-MG) and serum albumin in blood were quantitativelytested. Glucose, pH value, protein, cells, cast and ketobodies in urine were assayed.Diagnosis of cataract was based on lens opacities classification system Ⅱ. Any patientmeeting "NⅡ", "CⅡ" or "PⅡ" level was diagnosed as cataract.Results: The incidence of cataract in this group of NIDDM was 62.37 % (494/792),which significantly related to the duration of the disease course, but not to the sex of thepatient. The occurrence rate of cataract in patients suffering from NIDDM of less thanfive years duration, from five to ten years, and more than ten years was 49.67 % (228/459), 71.84 % (125/174), and 88.68 % (141/159), respectively. The occurrence ofcataract in patients diagnosed of the disease from five to ten years and more than tenyears was much higher than that of those with the course of the disease less than fiveyears( P < 0.05 and P < 0. 001, respectively) . Rising concentrations of blood ureanitrogen, creatinine, glycosylated hemoglobin HbA1c(G-HbA1c), N-acetyl-β2-D-glucosaminidase(NAG) and β2-microglobulin(β2-MG) indicated malfunction of thekidneys, and the rate of cataract occurrence in these patients was higher.Conclusion: This study indicates that prolongation of the duration of non-insulindependent diabetes mellitus, renal dysfunction, as well as poor blood glucose control,may accelerate the development of cataract.展开更多

HG has been reported to be a very rare disease, although it is believed to be extremely underdiagnosed because it is not possible to distinguish it from non-alcoholic fatty liver disease(NAFLD) unless a liver biopsy is performed. In contrast to HG, NAFLD is characterized by liver fat accumulation and is the more likely diagnosis for patients with type 2 diabetes and metabolic syndrome. The pathogenesis of HG involves the concomitant presence of insulin and excess glucose, which increases glycogen storage in the liver. HG is characterized by a transient elevation in liver transaminases and hepatomegaly. Differentiating between these two conditions is of the utmost importance because HG is a benign disease that is potentially reversible by improving glycemic control, whereas NAFLD can progress to cirrhosis. Therefore, HG should be suspected when liver dysfunction occurs in patients with poorly controlled T1 D. The aim of this article is to review the epidemiology, clinical characteristics, pathogenesis and histology of HG.展开更多

New tools, such as genome-wide association studies, have provided evidence for new susceptibility loci and candidate genes in the disease process including common susceptibility genes involved in the immunological synapse and T cell activation. Close linkages have been found in a number of diseases, including ankylosing spondylitis, multiple sclerosis, Crohn’s disease and insulin-dependent diabetes mellitus (Type 1 diabetes mellitus). The evidence for some associations with Type 1 diabetes was previously found in the region containing 5q15/ERAP1 (endoplasmic reticulum aminopeptidase 1) (rs30187, ARTS1). Our aim was to conduct the first casecontrol study to test the association between the rs30187 polymorphism of ERAP1 and the development of Type 1 diabetes mellitus in patients selected from continental Italy. All control subjects were matched for the sex, age, ethnic origin and geographical area. Genotyping of the rs30187 polymorphism of ERAP1 was carried out by the allelic discrimination assay on DNA extracted from whole blood. We did not observe a statistically significant prevalence of the rs30187 polymorphism of ERAP1 in our cohort of patients than in controls suggesting a minor contribution of this gene to the pathogenesis of Type 1 diabetes mellitus in Italian patients.展开更多

There has been growing speculation about rural dwellers not being susceptible to this ailment due to their lifestyle. However, this could be attributed to the paucity of data obtained from rural communities. This community-based survey was conducted to provide recent data about the prevalence of DM in a rural community in Northern Nigeria. <strong>Subject and Methods: </strong>Purposive sampling was used to recruit 78 participants from about 200 adults within the community in September 2019. Consent was obtained to retrieve their blood glucose results and socio-demographic data from an out-patient clinic. Data were entered and analyzed using SPSS version 20. <strong>Results:</strong> Over half (55%) of the respondents were male, while majority (88%) were involved in agrarian professions. Majority (69%) of the respondents were between 18 to 35 years, while around 10% were over 50 years. The respondents had an average blood glucose level of 5.20 ± 0.62 mmol/L, with 6.50 mmol/L as the maximum reading. The prevalence of DM was 0.0%, majority (68%) had normal glucose level, while the remainder had pre-diabetes glucose levels. There were no statistically significant associations between the respondents’ blood glucose level and any of their socio-demographic characteristics. However, the oldest respondents, male respondents, and traders had the highest blood glucose levels in their respective categories. <strong>Conclusion:</strong> The absence of a healthcare center in the community was of concern, as this would impede efforts to monitor the prevalence of non-communicable disease like DM. It is recommended that health interventions to discourage the rural dwellers from embracing adverse urban lifestyles associated with DM should be prioritized.展开更多

Methods STRs including D11S916 of uncoupling protein 3 (UCP3) gene,binucleotide repeat (CA)n within intron 6 [HSLi6(CA)] of hormone-sensitive lipase(HSL)gene and D20S501 of protein tyrosine phosphatase-1B (PTP-1B)gene polymorphisms were detected, by poiymerase chain reaction(PCR) ,poly-acrylamide gel electrophoresis and silver staining in 106 patients with type 2 DM and 102 control subjects. Results The allele distribution of UCP3 and HSL gene differed significantly between patients with type 2 diabetes and control subjects (X2 = 26. 12,P<0. 005; X2 = 10. 33,P<0. 005,respectively). For UCP3 and HSL gene,the frequencies of alleles A6,A7,A8 and allele B9 were much higher in diabetic patients than in control subjects (0. 090 vs 0. 020,P<0. 005; 0. 109 vs 0. 015,P <0. 005; 0. 033 vs 0. 000,P<0. 05; 0. 033 vs 0. 005,P<0. 05,respectively),while the frequencies of allele A1 and allele B5 were lower in diabetic patients than in control subjects (0. 090 vs 0. 206,P<0. 005; 0. 057 vs 0. 118,P<0. 05,respectively). At D20S501 locus,The allele distribution of PTP-1B gene had no significant difference in two groups (X2 = 3. 77, P>0. 05). Multi-variate logistic regression analysis showed positive correlation between alleles A6,A7 of UCP3 gene,systolic blood pressure, apolipoprotein B, lipoprotein (a) and type 2 diabetes. Conclusion Our data show that D11S916 of UCP3 gene and HSLi6(CA) of HSL gene polymorphisms are associated with type 2 diabetes in Chinese suggesting that UCP3 and HSL might represent susceptibility genes for type 2 diabetes. D20S501 of PTP-IB gem polymorphism is not associated with type 2 diabetes in Chinese. Alleles A6, A7 of UCP3 gene, systolic blood pressure, apolipoprotein B,Upoprotein (a) may play some role in the development of type 2 diabetes.展开更多

Screening the general population has debatable advantages. This study aims to determine whether spouses of patients with diabetes mellitus have higher random blood glucose (RBG) levels as well as the benefit of RBG testing as a targetted screening tool. Methodology: The survey employed a cross-sectional comparative study of spouses’ of diabetics and non-diabetics attending the general out-patient department of the LagosStateUniversityTeaching Hospital (LASUTH), Ikeja. A modified WHO STEPS Surveillance Instrument and a one-touch Glucometer were used to collect data. Blood pressures and BMI were measured and correlated to blood glucose levels. Results: Prevalence of high RBG was found to be 7% among spouses of diabetics and 3.3% among spouses of non-diabetic patients. Mean RBG was 5.57 mmol/L and 7.7 mmol/L within the age group 40 - 49 years and 50 - 59 years respectively among spouses of diabetic patients compared to 5.4 mmol/L and 5.5 mmol/L within the same age group among the spouses non-diabetics. Spouses of patients with diabetes mellitus had higher systolic and diastolic blood pressures and BMI compared to spouses of non-diabetics. Conclusion: Being male, married to a diabetic patient, lower educational levels and higher body mass index are significantly associated with higher random blood glucose in the spouses of diabetic patients. Random blood glucose measurements are an effective screening tool and spouses of diabetic patients can benefit from targeted screening in controlled clinical settings.展开更多

The purpose of this study is to evaluate whether diabetes affects the patterns of use in chemotherapy, toxic effects of chemotherapy, and treatment outcomes for non-metastatic breast cancer in Taiwan. The study results can provide physicians for making a decision whether or not to use chemotherapy based on the individual patients' condition.展开更多

METHODS: Group 1(control) received artificial tears substitute as a placebo group, group 2(nepafenac) received topical nepafenac 0.1%, and group 3(ketorolac) received topical ketorolac tromethamine 0.4%. Patients were examined postoperatively after completing one week, one month, two months and three months' intervals for evaluating cystoid macular edema(CME) development. The main study outcomes were achieving the best corrected visual acuity(BCVA) and change in the central macular thickness(CMT) measured with optical coherence topography(OCT).RESULTS: Eighty eyes of 76 patients were included in this study. BCVA showed a statistically significant difference at the third month postoperative follow up between the control group and the NSAIDs groups(P=0.04). There was an increase in the CMT in all cases starting from postoperative first week until third month. CMT showed a statistically significant difference between control group and NSAIDs groups from postoperative first month until third month(P=0.008, 0.027, 0.004). There was no statistically significant difference between nepafenac and ketorolac groups in BCVA and OCT CMT. CONCLUSION: Prophylactic preoperative and postoperative NSAIDs may have a role in reducing the frequency and severity of CME in diabetic eyes following cataract surgery.展开更多
文摘To explore the role of obese protein (OP), the product of the obese gene, in the development of non-insulin-dependent diabetes mellitus (NIDDM). Metbods: Plasma obese protein level was measured by radioimmunoassay in 21 normal subjects, 24 adult obese patients and 20 patients with NIDDM. Results: The levels of the plasma obese protein in NIDDM patients (81. 0±17. 5 pg/ml) were very significantly lower than those in normal subjects (194. 3±17. 7 pg/ml) and obese patients (109.1±16. 4 pg/ml ) (P<0.01). The levels of the plasma obese protein in non-obese NIDDM patients were very significantly lower than those in non-obese normal subjects (P<0.01), and the levels of the plasma obese protein in obese NIDDM patients were very significantly lower than those in obese patients (P<0. 01). The leve1s of the plasma obese protein in NIDDM patients were significantly correlated with polyphagia (P<0.05), but not correlated with the body weight indexes after strict dieting, and the plasma levels of cholesterol, triglyceride, fasting glucose, hemoglobiti A, and the insulin levels during glucose tolerance test (P>0.05). Couclusion: Low plasma level of obese protein is one of the important factors contributing to obesity,and plasma obese protein may be closely related to the generation of NIDDM.
文摘Non-alcoholic fatty liver disease(NAFLD) is a chronic liver disease that might affect up to one-third of the adult population in industrialised countries. NAFLD incorporates histologically and clinically different nonalcoholic entities; fatty liver(NAFL, steatosis hepatis)and steatohepatitis(NASH-characterised by hepatocyte ballooning and lobular inflammation ± fibrosis) might progress to cirrhosis and rarely to hepatocellular cancer.NAFL increasingly affects children(paediatric prevalence is 4.2%-9.6%). Type 2 diabetes mellitus(T2DM),insulin resistance(IR), obesity, metabolic syndrome and NAFLD are particularly closely related. Increased hepatic lipid storage is an early abnormality in insulin resistant women with a history of gestational diabetes mellitus. The accumulation of triacylglycerols in hepatocytes is predominantly derived from the plasma nonesterified fatty acid pool supplied largely by the adipose tissue. A few NAFLD susceptibility gene variants are associated with progressive liver disease, IR, T2 DM and a higher risk for hepatocellular carcinoma. Although not approved, pharmacological approaches might be considered in NASH patients.
文摘Background: Diabetes mellitus (DM) is the leading cause of end stage renal disease (ESRD) worldwide. Although DM with proteinuria is the ultimate result of diabetic nephropathy (DN), a wide spectrum of non-diabetic renal diseases (NDRD) can occur in such patients. Objective: To observe the frequency and histological pattern of NDRD in diabetic patients with proteinuria and to explore their association with clinical and laboratory parameters. Methods: This cross-sectional study was conducted in the Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from April 2016 to September 2017. In this study a total of 38 cases of DM with proteinuria (>1 gm/24-hour) were selected purposively. Renal biopsy was done in all patients. Based on histological findings they were categorized into two groups;Group 1 with NDRD and Group II with DN. Their clinical and laboratory parameters were analyzed and compared. Results: Among the total study subjects, 21 (55.3%) were male and 17 (44.7%) were female, mean (±SD) age 43.45 ± 9.99 years in the NDRD group and 41.57 ± 9.50 years in the DN group. Thirty one cases (81.6%) out of thirty eight had NDRD and seven (18.4%) cases had isolated DN;therefore more than two third cases had NDRD. Duration of DM was found to be significantly shorter (p = 0.004) in the NDRD group. Diabetic retinopathy was present in 12.9% cases in NDRD group vs. 57.1% cases in DN group (p = 0.025). Frequency of microscopic hematuria was significantly higher (90.3%) in NDRD patients (p = 0.002). Conclusion: The frequency of NDRD in type 2 diabetic patients other than diabetic nephropathy is relatively high. Membrano proliferative glomeru-lonephritis and membranous nephropathy are more common in NDRD. Absence of diabetic retinopathy, presence of hematuria and shorter duration of DM are markers associated with NDRD in type 2 DM, which are important indicators for renal biopsy in diabetic patients with proteinuria.
文摘Transplantation therapy for diabetes in humans is limited by the low availability of human donor whole pancreas or islets. Outcomes are complicated by immunosuppressive drug toxicity. Xenotransplantation is a strategy to overcome supply problems. Implantation of tissue obtained early during embryogenesis is a way to reduce transplant immunogenicity. Pig insulin is biologically active in humans. In that regard the pig is an appropriate xenogeneic organ donor. Insulin-producing cells originating from embryonic pig pancreas obtained very early following pancreatic primordium formation [embryonic day 28 (E28)] engraft long-term in rhesus macaques. Endocrine cells originating from embryonic pig pancreas transplanted in host mesentery migrate to mesenteric lymph nodes, engraft, differentiate and improve glucose tolerance in rhesus macaques without the need for immune suppression. Transplantation of embryonic pig pancreas is a novel approach towards beta cell replacement therapy that could be applicable to humans.
文摘Purpose: To investigate the factors related to the development of cataract in patientswith non-insulin dependent diabetes mellitus(NIDDM).Methods: 792 NIDDM patients received ophthalmologic examinations including visualacuity, external status of the eyes, slit lamp microscopy and ophthalmoscopy. Glucose,urea nitrogen (BUN), creatinine (Cr), urine acid (UA), N-acetyl-β2-D-glucosaminidase(NAG), β2-microglobulin(β2-MG) and serum albumin in blood were quantitativelytested. Glucose, pH value, protein, cells, cast and ketobodies in urine were assayed.Diagnosis of cataract was based on lens opacities classification system Ⅱ. Any patientmeeting "NⅡ", "CⅡ" or "PⅡ" level was diagnosed as cataract.Results: The incidence of cataract in this group of NIDDM was 62.37 % (494/792),which significantly related to the duration of the disease course, but not to the sex of thepatient. The occurrence rate of cataract in patients suffering from NIDDM of less thanfive years duration, from five to ten years, and more than ten years was 49.67 % (228/459), 71.84 % (125/174), and 88.68 % (141/159), respectively. The occurrence ofcataract in patients diagnosed of the disease from five to ten years and more than tenyears was much higher than that of those with the course of the disease less than fiveyears( P < 0.05 and P < 0. 001, respectively) . Rising concentrations of blood ureanitrogen, creatinine, glycosylated hemoglobin HbA1c(G-HbA1c), N-acetyl-β2-D-glucosaminidase(NAG) and β2-microglobulin(β2-MG) indicated malfunction of thekidneys, and the rate of cataract occurrence in these patients was higher.Conclusion: This study indicates that prolongation of the duration of non-insulindependent diabetes mellitus, renal dysfunction, as well as poor blood glucose control,may accelerate the development of cataract.
文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD)is a common comorbidity with type 2 diabetes.The existing therapeutic options for NAFLD are not adequate.Hypocaloric diet and exercise is the cornerstone of therapy in NAFLD.Pioglitazone is the only drug recommended in diabetes patients with biopsy proven non-alcoholic steatohepatitis.The frequent coexistence of NAFLD and type 2 diabetes with their combined adverse health consequences and inadequate therapeutic options makes it necessary to search for newer alternatives.AIM To assess the effect of sodium glucose cotransporter-2(SGLT-2)inhibitors on liver enzymes in type 2 diabetes patients with NAFLD.METHODS We searched PubMed/MEDLINE,Cochrane library,Google scholar,and Clinicaltrials.gov for the relevant articles to be included in this systematic review.Human studies done in type 2 diabetes patients with NAFLD treated with SGLT-2 inhibitors for at least 12 wk were included.Data from eight studies(four randomised controlled trials and four observational studies)were extracted and a narrative synthesis was done.A total of 214 patients were treated with SGLT-2 inhibitors in these studies(94 in randomised controlled trials and 120 in observational studies).RESULTS The primary outcome measure was change in serum alanine aminotransferase level.Out of eight studies,seven studies showed a significant decrease in serum alanine aminotransferase level.Most of the studies revealed reduction in serum level of other liver enzymes like aspartate aminotransferase and gamma glutamyl transferase.Five studies that reported a change in hepatic fat exhibited a significant reduction in hepatic fat content in those treated with SGLT-2 inhibitors.Likewise,among the three studies that evaluated a change in indices of hepatic fibrosis,two studies revealed a significant improvement in liver fibrosis.Moreover,there was an improvement in obesity,insulin resistance,glycaemia,and lipid parameters in those subjects taking SGLT-2 inhibitors.The studies disclosed that about 17%(30/176)of the subjects taking SGLT-2 inhibitors developed adverse events and more than 40%(10/23)of them had genitourinary tract infections.CONCLUSION Based on low to moderate quality of evidence,SGLT-2 inhibitors improve the serum level of liver enzymes,decrease liver fat,and fibrosis with additional beneficial effects on various metabolic parameters in type 2 diabetes patients with NAFLD.
文摘Hepatic glycogenosis(HG) is characterized by excessive glycogen accumulation in hepatocytes and represents a hepatic complication of diabetes that particularly occurs in patients with longstanding poorly controlled type 1 diabetes(T1D). HG has been reported to be a very rare disease, although it is believed to be extremely underdiagnosed because it is not possible to distinguish it from non-alcoholic fatty liver disease(NAFLD) unless a liver biopsy is performed. In contrast to HG, NAFLD is characterized by liver fat accumulation and is the more likely diagnosis for patients with type 2 diabetes and metabolic syndrome. The pathogenesis of HG involves the concomitant presence of insulin and excess glucose, which increases glycogen storage in the liver. HG is characterized by a transient elevation in liver transaminases and hepatomegaly. Differentiating between these two conditions is of the utmost importance because HG is a benign disease that is potentially reversible by improving glycemic control, whereas NAFLD can progress to cirrhosis. Therefore, HG should be suspected when liver dysfunction occurs in patients with poorly controlled T1 D. The aim of this article is to review the epidemiology, clinical characteristics, pathogenesis and histology of HG.
文摘Autoimmune diseases are a heterogeneous group of disorders affecting different organs and tissues whose incidence are increasing worldwide. New tools, such as genome-wide association studies, have provided evidence for new susceptibility loci and candidate genes in the disease process including common susceptibility genes involved in the immunological synapse and T cell activation. Close linkages have been found in a number of diseases, including ankylosing spondylitis, multiple sclerosis, Crohn’s disease and insulin-dependent diabetes mellitus (Type 1 diabetes mellitus). The evidence for some associations with Type 1 diabetes was previously found in the region containing 5q15/ERAP1 (endoplasmic reticulum aminopeptidase 1) (rs30187, ARTS1). Our aim was to conduct the first casecontrol study to test the association between the rs30187 polymorphism of ERAP1 and the development of Type 1 diabetes mellitus in patients selected from continental Italy. All control subjects were matched for the sex, age, ethnic origin and geographical area. Genotyping of the rs30187 polymorphism of ERAP1 was carried out by the allelic discrimination assay on DNA extracted from whole blood. We did not observe a statistically significant prevalence of the rs30187 polymorphism of ERAP1 in our cohort of patients than in controls suggesting a minor contribution of this gene to the pathogenesis of Type 1 diabetes mellitus in Italian patients.
文摘<strong>Aim: </strong>Diabetes mellitus (DM) is an emerging disease of public health concern in Nigeria. There has been growing speculation about rural dwellers not being susceptible to this ailment due to their lifestyle. However, this could be attributed to the paucity of data obtained from rural communities. This community-based survey was conducted to provide recent data about the prevalence of DM in a rural community in Northern Nigeria. <strong>Subject and Methods: </strong>Purposive sampling was used to recruit 78 participants from about 200 adults within the community in September 2019. Consent was obtained to retrieve their blood glucose results and socio-demographic data from an out-patient clinic. Data were entered and analyzed using SPSS version 20. <strong>Results:</strong> Over half (55%) of the respondents were male, while majority (88%) were involved in agrarian professions. Majority (69%) of the respondents were between 18 to 35 years, while around 10% were over 50 years. The respondents had an average blood glucose level of 5.20 ± 0.62 mmol/L, with 6.50 mmol/L as the maximum reading. The prevalence of DM was 0.0%, majority (68%) had normal glucose level, while the remainder had pre-diabetes glucose levels. There were no statistically significant associations between the respondents’ blood glucose level and any of their socio-demographic characteristics. However, the oldest respondents, male respondents, and traders had the highest blood glucose levels in their respective categories. <strong>Conclusion:</strong> The absence of a healthcare center in the community was of concern, as this would impede efforts to monitor the prevalence of non-communicable disease like DM. It is recommended that health interventions to discourage the rural dwellers from embracing adverse urban lifestyles associated with DM should be prioritized.

文摘Objectives To explore the relationship between the polymorphisms of the selected short tandem repeats (STRs) of the candidate genes and type 2 diabetes mellitus (DM) in a Chinese population,the role of genetic and environmental factors in the development of type 2 diabetes. Methods STRs including D11S916 of uncoupling protein 3 (UCP3) gene,binucleotide repeat (CA)n within intron 6 [HSLi6(CA)] of hormone-sensitive lipase(HSL)gene and D20S501 of protein tyrosine phosphatase-1B (PTP-1B)gene polymorphisms were detected, by poiymerase chain reaction(PCR) ,poly-acrylamide gel electrophoresis and silver staining in 106 patients with type 2 DM and 102 control subjects. Results The allele distribution of UCP3 and HSL gene differed significantly between patients with type 2 diabetes and control subjects (X2 = 26. 12,P<0. 005; X2 = 10. 33,P<0. 005,respectively). For UCP3 and HSL gene,the frequencies of alleles A6,A7,A8 and allele B9 were much higher in diabetic patients than in control subjects (0. 090 vs 0. 020,P<0. 005; 0. 109 vs 0. 015,P <0. 005; 0. 033 vs 0. 000,P<0. 05; 0. 033 vs 0. 005,P<0. 05,respectively),while the frequencies of allele A1 and allele B5 were lower in diabetic patients than in control subjects (0. 090 vs 0. 206,P<0. 005; 0. 057 vs 0. 118,P<0. 05,respectively). At D20S501 locus,The allele distribution of PTP-1B gene had no significant difference in two groups (X2 = 3. 77, P>0. 05). Multi-variate logistic regression analysis showed positive correlation between alleles A6,A7 of UCP3 gene,systolic blood pressure, apolipoprotein B, lipoprotein (a) and type 2 diabetes. Conclusion Our data show that D11S916 of UCP3 gene and HSLi6(CA) of HSL gene polymorphisms are associated with type 2 diabetes in Chinese suggesting that UCP3 and HSL might represent susceptibility genes for type 2 diabetes. D20S501 of PTP-IB gem polymorphism is not associated with type 2 diabetes in Chinese. Alleles A6, A7 of UCP3 gene, systolic blood pressure, apolipoprotein B,Upoprotein (a) may play some role in the development of type 2 diabetes.
文摘Introduction: Diabetes mellitus type 2 is a growing threat in developing countries already burdened with high levels of infectious disease. Screening the general population has debatable advantages. This study aims to determine whether spouses of patients with diabetes mellitus have higher random blood glucose (RBG) levels as well as the benefit of RBG testing as a targetted screening tool. Methodology: The survey employed a cross-sectional comparative study of spouses’ of diabetics and non-diabetics attending the general out-patient department of the LagosStateUniversityTeaching Hospital (LASUTH), Ikeja. A modified WHO STEPS Surveillance Instrument and a one-touch Glucometer were used to collect data. Blood pressures and BMI were measured and correlated to blood glucose levels. Results: Prevalence of high RBG was found to be 7% among spouses of diabetics and 3.3% among spouses of non-diabetic patients. Mean RBG was 5.57 mmol/L and 7.7 mmol/L within the age group 40 - 49 years and 50 - 59 years respectively among spouses of diabetic patients compared to 5.4 mmol/L and 5.5 mmol/L within the same age group among the spouses non-diabetics. Spouses of patients with diabetes mellitus had higher systolic and diastolic blood pressures and BMI compared to spouses of non-diabetics. Conclusion: Being male, married to a diabetic patient, lower educational levels and higher body mass index are significantly associated with higher random blood glucose in the spouses of diabetic patients. Random blood glucose measurements are an effective screening tool and spouses of diabetic patients can benefit from targeted screening in controlled clinical settings.

文摘Throughout the globe,diabetes mellitus(DM) is increasing in incidence with limited therapies presently available to prevent or resolve the significant complications of this disorder.DM impacts multiple organs and affects all components of the central and peripheral nervous systems that can range from dementia to diabetic neuropathy.The mechanistic target of rapamycin(m TOR) is a promising agent for the development of novel regenerative strategies for the treatment of DM.m TOR and its related signaling pathways impact multiple metabolic parameters that include cellular metabolic homeostasis,insulin resistance,insulin secretion,stem cell proliferation and differentiation,pancreatic β-cell function,and programmed cell death with apoptosis and autophagy.m TOR is central element for the protein complexes m TOR Complex 1(m TORC1) and m TOR Complex 2(m TORC2) and is a critical component for a number of signaling pathways that involve phosphoinositide 3-kinase(PI 3-K),protein kinase B(Akt),AMP activated protein kinase(AMPK),silent mating type information regulation 2 homolog 1(Saccharomyces cerevisiae)(SIRT1),Wnt1 inducible signaling pathway protein 1(WISP1),and growth factors.As a result,m TOR represents an exciting target to offer new clinical avenues for the treatment of DM and the complications of this disease.Future studies directed to elucidate the delicate balance m TOR holds over cellular metabolism and the impact of its broad signaling pathways should foster the translation of these targets into effective clinical regimens for DM.

文摘AIM:To explore the mechanism of action of gypenosides(GPs)on type 2 diabetes mellitus and non-alcoholic fatty liver disease(T2DM-NAFLD)in rats.METHODS:Sixty rats were randomly divided into a healthy group,an untreated disease model group andGP-treatment groups.The study involved the evaluation of biochemical parameters,including serum aspartate transaminase(AST),alanine transferase(ALT),blood glucose(BG),triglycerides(TG)and total cholesterol(TC).Additionally,the protective effect of the treatments were confirmed histopathologically and the expression of TNF-αand NF-κB in the rat liver was analyzed using immunohistochemistry.The expression of proliferatoractivated receptor gamma(PPARγ)and cytochrome P450(CYP450)1A1 m RNA was determined by quantitative RTPCR.RESULTS:GP treatments at oral doses of 200,400,and800 mg/kg per day significantly decreased the levels of serum AST and ALT(P<0.05,P<0.01),especially at the dose of 800 mg/kg per day.To a similar extent,GP at800 mg/kg per day reduced the levels of BG(4.19±0.47,P<0.01),TG(80.08±10.05,P<0.01),TC(134.38±16.39,P<0.01)and serum insulin(42.01±5.04,P<0.01).The expression of TNF-αand NF-κB measured by immunohistochemistry was significantly reduced by GPs in a dose-dependent manner,and the expression of PPARγand CYP4501A1 m RNA,as measured using quantitative real-time PCR,were significantly down-regulated by GPs.Moreover,GPs decreased the infiltration of liver fats and reversed the histopathological changes in a dosedependent manner.CONCLUSION:This study suggests that GPs have a protective effect against T2DM-NAFLD by down-regulating the expression of TNF-αand NF-κB proteins,and PPARγand CYP4501A1 m RNAs.

文摘Non-alcoholic fatty liver disease(NAFLD)is highly prevalent in patients with diabetes mellitus and increasing evidence suggests that patients with type 2diabetes are at a particularly high risk for developing the progressive forms of NAFLD,non-alcoholic steatohepatitis and associated advanced liver fibrosis.Moreover,diabetes is an independent risk factor for NAFLD progression,and for hepatocellular carcinoma development and liver-related mortality in prospective studies.Notwithstanding,patients with NAFLD have an elevated prevalence of prediabetes.Recent studies have shown that NAFLD presence predicts the development of type2 diabetes.Diabetes and NAFLD have mutual pathogenetic mechanisms and it is possible that genetic and environmental factors interact with metabolic derangements to accelerate NAFLD progression in diabetic patients.The diagnosis of the more advanced stages of NAFLD in diabetic patients shares the same challenges as in non-diabetic patients and it includes imaging and serological methods,although histopathological evaluation is still considered the gold standard diagnostic method.An effective established treatment is not yet available for patients with steatohepatitis and fibrosis and randomized clinical trials including only diabetic patients are lacking.We sought to outline the published data including epidemiology,pathogenesis,diagnosis and treatment of NAFLD in diabetic patients,in order to better understand the interplay between these two prevalent diseases and identify the gaps that still need to be fulfilled in the management of NAFLD in patients with diabetes mellitus.
文摘Periodontal disease is a high prevalent disease.In the United States 47.2% of adults ≥ 30 years old have been diagnosed with some type of periodontitis.Longitudinal studies have demonstrated a two-way relationship between diabetes and periodontitis,with more severe periodontal tissue destruction in diabetic patients and poorer glycemic control in diabetic subjects with periodontal disease.Periodontal treatment can be successful in diabetic patients.Short term effects of periodontal treatment are similar in diabetic patients and healthy population but,more recurrence of periodontal disease can be expected in no well controlled diabetic individuals.However,effects of periodontitis and its treatment on diabetes metabolic control are not clearly defined and results of the studies remain controversial.

文摘Objective:To explore demographic and metabolic factors associated with increased alanine aminotransferase(ALT)activity in non-diabetic non-alcoholic fatty liver disease(NAFLD)patients.Methods:Overall 372 patients who consecutively attended to Gastroenterology Clinic of Baqiyatallah University of Medical Sciences,Tehran,Iran awere diagnosed as NAFLD entered into analysis.Exclusion criteria were having diabetes mellitus and fasting blood glucose over126 mg/dL,active hepatitis B virus infection,having hepatitis C virus positive serology,and to be under corticosteroid therapy.ALT levels were considered pathologically high when it was over30 IU/L for men and over 19 IU/L for women.Results:Bivariate analyses using t test and chisquare test showed that patients with pathologically augmented ALT levels had significantly higher NAFLD grades in their ultrasonographic evaluations(P=0.003).Moreover,these patients represented significantly higher homeostatic model assessment levels(P=0.003),levels of serum insulin(P=0.002),fasting blood glucose(P<0.001),and uric acid(P=0.02).The prevalence of insulin resistance was also higher in patients with increased serum ALT concentrations.Multifactorial logistic regression models showed that ultrasonographic grading of NAFLD(P=0.027)and insulin resistance(P=0.013)were the only variables significantly associated with abnormal ALT levels.Conclusions:This study shows that the associations of increased ALT serum levels in NAFLD patients are different from what are supposed before.By excluding diabetic patients from our population,we find that increased ALT levels are not associated with dyslipidemias but are independently associated with insulin resistance and NAFLD grading on ultrasonographic evaluations.Further studies are needed to confirm our results.
文摘AIM: To evaluate the efficacy of prophylactic administration of topical non-steroidal anti-inflammatory drugs(NSAIDs) on macular edema following cataract surgery in diabetic patients, and to compare between types of NSAIDs(ketorolac tromethamine 0.4% and nepafenac 0.1%). METHODS: Group 1(control) received artificial tears substitute as a placebo group, group 2(nepafenac) received topical nepafenac 0.1%, and group 3(ketorolac) received topical ketorolac tromethamine 0.4%. Patients were examined postoperatively after completing one week, one month, two months and three months' intervals for evaluating cystoid macular edema(CME) development. The main study outcomes were achieving the best corrected visual acuity(BCVA) and change in the central macular thickness(CMT) measured with optical coherence topography(OCT).RESULTS: Eighty eyes of 76 patients were included in this study. BCVA showed a statistically significant difference at the third month postoperative follow up between the control group and the NSAIDs groups(P=0.04). There was an increase in the CMT in all cases starting from postoperative first week until third month. CMT showed a statistically significant difference between control group and NSAIDs groups from postoperative first month until third month(P=0.008, 0.027, 0.004). There was no statistically significant difference between nepafenac and ketorolac groups in BCVA and OCT CMT. CONCLUSION: Prophylactic preoperative and postoperative NSAIDs may have a role in reducing the frequency and severity of CME in diabetic eyes following cataract surgery.
