DM Patients (dm + patient)
Kinds of DM Patients Selected AbstractsPresence of Biventricular Dysfunction in Patients With Type II Diabetes MellitusCONGESTIVE HEART FAILURE, Issue 2 2007Mohammad-Reza Movahed MD Diabetes mellitus (DM) has been found to be associated with depressed left ventricular (LV) function. Right ventricular (RV) function in DM patients, however, has not been well studied. The goal of this study was to evaluate the occurrence of LV and RV dysfunction in patients with DM. A series of 157 patients underwent simultaneous measurement of LV ejection fraction (LVEF) and RV ejection fraction (RVEF). Four of 26 DM patients had RVEF <30% (15.4%) vs 4 of 126 controls (3.2%) (P=.01). Eleven of 27 (40.7%) patients with DM had LVEF <30% vs 9 of 128 controls (7%) (P<.0001). Using multivariate analysis, DM remained independently associated with severely decreased biventricular function (RVEF <30%; odds ratio, 5.7; confidence interval, 1.3,25.4 [P=.02] and LVEF <30%; odds ratio, 12.9; confidence interval, 3.8,43.7 [P<.0001]). These results suggest that diabetic cardiomyopathy involves both ventricles as an independent pathologic process. [source] The effect of depression on quality of life of patients with type II diabetes mellitusDEPRESSION AND ANXIETY, Issue 2 2008brahim Eren M.D. Abstract Diabetes mellitus (DM) is a frequently encountered metabolic disease with chronic features and involves numerous complications throughout its course, which causes severe restriction and disability in an individual's life. It has been reported that the incidence of depression is higher in diabetic patients and that diabetes is one of the risk factors in the development of depression. It has also been reported that co-morbid psychiatric disorders cause further deterioration in the quality of life in diabetic patients. The aim of this study was to investigate the effects of depression on the quality of life in type II DM patients. Sixty patients (30 females and 30 males) with current major depressive episode diagnosed according to DSM-IV criteria, and 48 type II DM patients (30 females and 18 males) without a major depressive episode (non-depressed group) were included in the study. All patients were evaluated with a semi-structured interview form to assess the clinical features of DM, Hamilton Rating Scale for Anxiety (HRSA), Hamilton Rating Scale for Depression (HRSD), and the Turkish version of The World Health Organization Quality of Life Assessment-Brief (WHOQOL-BREF). The HRSD and HRSA scores in the depressed group were 24.87±4.83 and 21.07±5.44, respectively, whereas those in the non-depressed group were 7.83±3.92 and 6.88±3.43, respectively. The physical health, psychological health, social relationship, environmental and social pressure domain, general health-related quality of life, overall quality of life, and WHOQOL-BREF total scores were found significantly lower in the depressed group than the non-depressed group. There were significant negative correlations between HRSD and HRSA scores and physical health, psychological health, social relationship, environmental and social pressure domain, general health-related quality of life, overall quality of life, and WHOQOL-BREF total scores. Furthermore, there were significant negative correlations between the HbA1c level and physical health, social relationship, environmental domain, social pressure domain, general health-related quality of life, overall quality of life, and WHOQOL-BREF total scores. However, there was a significant positive correlation between the level of education and physical health, psychological health, social relationship, environmental social pressure domain, overall quality of life, and WHOQOL-BREF total scores. There were significant negative correlations between social relationship domain score, and age and duration of illness. Our study demonstrates that the presence of depression in type II DM further deteriorates the quality of life of the patients. Since treating depression would have a beneficial effect on the quality of life, clinicians should carefully assess for depression associated with type II DM.

[source] Glycaemic variability and complications in patients with diabetes mellitus: evidence from a systematic review of the literatureDIABETES OBESITY & METABOLISM, Issue 4 2010L. Nalysnyk Aim: The objective of this review was to assess the published evidence for an association between glycaemic variability and the development of chronic micro- and macrovascular complications in patients with diabetes mellitus (DM). Methods: A systematic review of English-language literature published from January 1990 through November 2008 was performed. Interventional and observational studies in patients with type 1 or type 2 DM reporting a measure of glycaemic variability and its impact on the development or progression of micro- and macrovascular diabetic complications were assessed. Results: A total of 18 studies ,8 on type 1 DM and 10 on type 2 DM patients,meeting the inclusion criteria were identified. Studies in patients with type 1 DM revealed that glucose variability has little impact on the development of diabetic complications. Only in two of the eight type 1 DM studies did glucose variability have a significant association with microvascular complications, but not with macrovascular complications. Among type 2 DM studies, a significant positive association between glucose variability and the development or progression of diabetic retinopathy, cardiovascular events and mortality was reported in 9 of 10 studies. Only one type 2 DM study reported no association between glucose variability and progression of retinopathy. Conclusions: Based on this overview of the available evidence, there appears to be a signal suggesting that glucose variability, characterized by extreme glucose excursions, could be a predictor of diabetic complications, independent of HbA1c levels, in patients with type 2 DM. Better daily control of blood glucose excursions, especially in the postprandial period, may reduce the risk of these complications. Future prospective trials evaluating and comparing the effect of the control of glycaemic variability on the development of diabetic micro- and macrovascular complications are needed to further strengthen the evidence base. [source] Glycaemic control in relation to xanthine oxidase and antioxidant indices in Malaysian Type 2 diabetes patientsDIABETIC MEDICINE, Issue 10 2005U. R. Kuppusamy Abstract Aims Increased oxidative stress and oxidative damage are present in Type 2 diabetes mellitus (DM). The aim of this study was to assess the oxidative stress levels in the three major ethnic groups in Malaysia and to study the association between glycaemic control and oxidant,antioxidant levels in these patients. Methods Oxidative indices and glycaemic control were assessed in 650 Type 2 DM patients and 280 healthy age-matched controls by known established methods. Results Type 2 DM patients had significantly lower levels of antioxidant enzymes and non-enzymatic antioxidant (FRAP) and increased levels of HbA1c, fasting blood glucose (FBG), malondialdehyde (MDA) and xanthine oxidase (XO) when compared with control subjects. Markers of oxidative stress were more apparent in Indian patients compared with Malay and Chinese patients. Correlation analysis of oxidant,antioxidant parameters as a function of HbA1c in each ethnic group revealed a strong association of HbA1c with oxidative indices. Conclusions The present study provides evidence for the possible contribution of XO to oxidative stress and the pathophysiology of diabetes. HbA1c remains an important marker of glycaemic control for the management of Type 2 DM, but other confounding factors that predispose or lead to oxidative stress should also be taken into consideration. [source] Ethnicity and glycaemic control are major determinants of diabetic dyslipidaemia in MalaysiaDIABETIC MEDICINE, Issue 6 2001I. S. Ismail Abstract Aims To define the prevalence of dyslipidaemia in young diabetic patients in Peninsular Malaysia and the contributory factors of dyslipidaemia in these subjects. Methods This is a cross-sectional study involving 848 young diabetic patients from seven different centres, with representation from the three main ethnic groups. Clinical history and physical examination was done and blood taken for HbA1c, fasting glucose, total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol and triglycerides. Results The overall lipids were suboptimal, worse in Type 2 diabetes mellitus (DM) patients compared with Type 1 DM patients. Of the Type 2 patients, 73.2% had total cholesterol >,5.20 mmol/l, 90.9% had LDL-cholesterol >,2.60 mmol/l, 52.6% had HDL-cholesterol <,1.15 mmol/l and 27.3% had serum triglycerides >,2.30 mmol/l. There were ethnic differences in the lipid levels with the Malays having the highest total cholesterol (mean 6.19 mmol/l), and the highest LDL-cholesterol (mean 4.16 mmol/l), while the Chinese had the highest HDL-cholesterol (geometric mean 1.24 mmol/l). Ethnicity was an important determinant of total, LDL- and HDL-cholesterol in Type 2 DM, and LDL- and HDL-cholesterol and triglycerides in Type 1 DM. Glycaemic control was an important determinant of total, LDL-cholesterol and triglycerides in both Type 1 and Type 2 DM. Waist,hip ratio (WHR) was an important determinant of HDL-cholesterol and triglycerides in both types of DM. Gender was an important determinant of HDL-cholesterol in Type 2 DM, but not in Type 1 DM. Socioeconomic factors and diabetes care facilities did not have any effect on the dyslipidaemia. Conclusions The prevalence of dyslipidaemia was high especially in Type 2 DM patients. Ethnicity, glycaemic control, WHR, and gender were important determinants of dyslipidaemia in young diabetic patients. Diabet. Med. 18, 501,508 (2001) [source] Comparative cytological study of lymph node tuberculosis in HIV-infected individuals and in patients with diabetes in a developing countryDIAGNOSTIC CYTOPATHOLOGY, Issue 2 2002C.B. Sridhar B.Sc., M.B.B.S., M.D. Abstract Tuberculosis (TB) is a common infection affecting patients with human immunodeficiency virus (HIV) and diabetes mellitus (DM). With the increasing incidence of HIV infection and DM in a developing country like India, TB is definitely on the rise. In a given population, one expects to see these three diseases in varying combinations, such as HIV and TB, DM and TB, HIV and DM with TB. In such combinations TB may lack the characteristic clinical and histological picture due to the associated depressed cell-mediated immunity seen in both diseases and TB may have an unusual clinical presentation and cytology picture. In this retrospective study of 36 months, from January 1997 to December 1999, 109 cases diagnosed cytologically as tuberculous lymphadenitis and tested for HIV infection and investigated as well for DM were selected. Forty-six (42%) were nondiabetic HIV patients, 13 (12%) were non-HIV DM patients, and 50 (46%) had TB without HIV infection or DM. The coexistence of both HIV and DM was not noted. The cytomorphological characteristics supplemented by culture studies of each of these three groups were compared in detail and based on these four cytological patterns, Pattern 1, Pattern 2, Pattern 3, and Pattern 4 emerged and were characterized. This study highlights the usefulness of cytomorphology of the lymph nodes to characterize the cytopathological profile of TB in both HIV and DM, which have many clinical and immunological similarities, and indirectly postulate the extent of immune suppression and evolve effective strategies in the management of coexisting diseases. Such a comparative study has not been carried out in the past. Diagn. Cytopathol. 2002;26:75,80; DOI 10.1002/dc.10059 © 2002 Wiley-Liss, Inc. [source] Forearm vasoconstrictor response in uncomplicated type 1 diabetes mellitusEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 10 2006P. J. Van Gurp Abstract Background, According to the ,haemodynamic hypothesis', increased tissue perfusion predisposes to microangiopathy in diabetic patients. We hypothesized that the typical haemodynamic changes underlying the increased tissue perfusion can be explained by a decreased sympathetic nerve activity caused by chronic hyperglycaemia. In this study we investigated sympathetic activity in patients with uncomplicated type 1 diabetes mellitus (DM). Materials and methods, In 15 DM patients (DM duration 6·3 ± 3·8 year; HbA1c 7·9 ± 1·3%) and 16 age- and sex-matched healthy volunteers (Control), sympathetic nervous system activity was measured at rest (baseline) and during sympathoneural stimulation (lower body negative pressure (LBNP)) by means of interstitial and plasma noradrenaline (NA) sampling and power spectral analysis. Muscle sympathetic nerve activity (MSNA) was measured before (baseline) and during a cold pressure test. Forearm blood flow was measured during forearm vascular ,- and ,-adrenergic receptor blockade. Results, At baseline, forearm vascular resistance (FVR), plasma NA concentrations, MSNA and heart rate variability were similar in both groups. LBNP-induced vasoconstriction was significantly attenuated in the DM group compared with the Control group (,FVR: 12 ± 4 vs. 19 ± 3 arbitrary units, P < 0·05). The responses of plasma NA and heart rate variability did not differ. Conclusions,, Baseline FVR and sympathetic nerve activity are normal in patients with uncomplicated type 1 diabetes. However, the forearm vasoconstrictor response to sympathetic stimulation is attenuated, which cannot be attributed to an impaired sympathetic responsiveness. [source] Electrophysiological findings of peripheral neuropathy in newly diagnosed type II diabetes mellitusJOURNAL OF THE PERIPHERAL NERVOUS SYSTEM, Issue 4 2005Eugenia Rota Abstract This study was aimed at assessing the electrophysiological signs of peripheral neuropathy in diabetes mellitus (DM) type II patients at diagnosis. Nerve conduction studies (NCS) of median, ulnar, peroneal, tibial and sural nerves were performed in 39 newly diagnosed DM subjects and compared to those of 40 healthy controls. Metabolic indices were also investigated. Electrophysiological alterations were found in 32 (82%) of the DM patients, and more than half of them (62.2%) showed multiple (two to five) abnormal parameters. Because most of the subjects (84.4%) had from two to five nerves involved, these alterations were widespread in the seven nerves evaluated. Forty-two percent of the patients had NCS alterations suggestive of distal median mononeuropathy, implying that metabolic factors in DM make the median nerve more susceptible to focal entrapment. A reduced sensory nerve action potential (SNAP) amplitude was observed in the median nerve in 70% of the patients, in the ulnar in 69% and in the sural nerve only in 22%. In the presence of a decrease in the SNAP amplitude of the ulnar or median nerve, the SNAP amplitude of the sural nerve was normal in 82 or 80% of the subjects, respectively. This finding may be in keeping with a distal involvement of the sensory fibres, as explored by routine median or ulnar NCS. No correlation was found between metabolic indices and NCS parameters. In conclusion, a high percentage of newly diagnosed DM patients show signs of neuropathy, and upper limb nerve sensory NCS seem to be more sensitive in detecting it than lower limb NCS. [source] Towards an Understanding of Delusions of Misidentification: Four Case StudiesMIND & LANGUAGE, Issue 1 2000Nora Breen Four detailed cases of delusions of misidentification (DM) are presented: two cases of misidentification of the reflected self, one of reverse intermetamorphosis, and one of reduplicative paramnesia. The cases are discussed in the context of three levels of interpretation: neurological, cognitive and phenomenological. The findings are compared to previous work with DM patients, particularly the work of Ellis and Young (1990; Young, 1998) who found that loss of the normal affective response to familiar faces was a contributing factor in the Capgras delusion. The four cases presented suggest that this particular deficit is not a critical factor in the development of other forms of DM. [source] Reduction expression of thrombomodulin and endothelial cell nitric oxide synthase in dermatomyositisNEUROPATHOLOGY, Issue 4 2007Guang-li Shen Dermatomyositis (DM) is a systemic microvasculitis predominantly involving the capillaries. We investigated the expression of thrombomodulin (TM) and endothelial cell nitric oxide synthase (eNOS) in microvessels of DM patients. Twelve patients with acute or subacute onset of proximal muscle weakness and erythematous rash over their faces and shoulders were included in this study. Serum creatine phosphokinase was elevated in almost all patients. Electromyograph showed a myopathic pattern in all patients. Muscle biopsies were performed in all patients and 10 non-DM controls and studied with histological, enzyme histochemical and immunohistochemical staining. von Willebrand factor, TM and eNOS antibodies were used as the primary antibodies. Perifascicular degeneration and inflammatory cell infiltration in the perimysium were noted in almost all patients. Non-special esterase staining was markedly positive in capillary and microvascular endothelium. Marked reduction in TM and eNOS staining was noted in DM patients in perimysium microvessels and perifascicular area capillaries. Vascular lesions in DM were not only limited to capillaries. The low expression of TM and eNOS in microvessels suggests the anticoagulation and vasodilation functions of vascular endothelium is reduced. DM is an inflammatory vascular endothelial disease. [source] Suboptimal Glycemic Control, Independently of QT Interval Duration, Is Associated with Increased Risk of Ventricular Arrhythmias in a High-Risk PopulationPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 1 2006CAROL CHEN-SCARABELLI Background: Although cardiovascular disease is the leading cause of mortality in diabetic patients, little is known about the impact of glycemic control on ventricular tachycardia (VT). Objective: To investigate whether hemoglobin A1c (HbA1c) is associated with increased incidence of VT. Methods: A retrospective study of 336 implantable cardioverter-defibrillator patients (both diabetes mellitus (DM) and non-DM) was conducted. Results: HbA1c levels between 8% and 10% had a significant association with spontaneous VT, but not with QT/QTc. Conclusions: Glycemic index is a significant predictor of spontaneous VT, independently of QT interval. Optimal glycemic control may help reduce occurrence of VT and sudden cardiac death in high-risk DM patients. [source] Effect of nebulized albuterol on blood glucose in patients with diabetes mellitus with and without cystic fibrosisPEDIATRIC PULMONOLOGY, Issue 2 2005P. König MD Abstract Over 90% of cystic fibrosis (CF) patients are treated with bronchodilators, and 6% have diabetes. Some with asthma also have diabetes, and most are treated with bronchodilators. Systemic administration of adrenergic agents can cause increases in blood glucose, but the effect of inhaled agents is unclear. A double-blind study was performed on 10 patients with type 1 diabetes mellitus (DM) without CF (3 male, 7 female, mean age 25.5 years) and 9 patients with insulin-dependent CF-related diabetes (CFRD) (8 male, 1 female, mean age 21.9 years). On 2 separate days before 9 AM fasting and the morning dose of insulin, 2.5 mg of albuterol or nebulized placebo were given. Blood glucose was measured by finger stick with a glucose reflectance meter before and 15, 30, 45, and 60 min after treatment. No significant changes from baseline or differences between placebo and albuterol occurred in either group. The mean maximum increase from baseline in DM was 20 mg/dl on placebo, and 38 mg/dl on albuterol; in the CFRD, the respective changes were 7 and 7 mg/dl. Two DM patients had a >,50 mg/dl increase on albuterol vs. placebo; no CFRD patients had differences of such magnitude. DM patients had greater increases from baseline than CFRD patients on placebo and albuterol. Differences reached statistical significance at 30 and 45 min on placebo, and 45 min on albuterol. Albuterol 2.5 mg by nebulizer causes no clinically significant increases in blood glucose in DM or CFRD patients. Diabetes patients without CF have a significantly greater increase of glucose with time (placebo or albuterol) than CFRD patients. Pediatr Pulmonol. 2005; 40:105,108. © 2005 Wiley-Liss, Inc. [source] Interferon-stimulated gene 15 (ISG15) conjugates proteins in dermatomyositis muscle with perifascicular atrophyANNALS OF NEUROLOGY, Issue 1 2010Mohammad Salajegheh MD Objective We investigated interferon-stimulated gene 15 (ISG15), a poorly understood ubiquitin-like modifier, and its enzymatic pathway in dermatomyositis (DM), an autoimmune disease primarily involving muscle and skin. Methods We generated microarray data measuring transcript abundance for approximately 18,000 genes in each of 113 human muscle biopsy specimens, and studied biopsy specimens and cultured skeletal muscle using immunohistochemistry, immunoblotting proteomics, real-time quantitative polymerase chain reaction, and laser-capture microdissection. Results Transcripts encoding ISG15-conjugation pathway proteins were markedly upregulated in DM with perifascicular atrophy (DM-PFA) muscle (ISG15 339-fold, HERC5 62-fold, and USP18 68-fold) compared with 99 non-DM samples. Combined analysis with publicly available microarray datasets showed that >50-fold ISG15 transcript elevation had 100% sensitivity and specificity for 28 biopsies from adult DM-PFA and juvenile DM patients compared with 199 muscle samples from other muscle diseases. Free ISG15 and ISG15-conjugated proteins were only found on immunoblots from DM-PFA muscle. Cultured human skeletal muscle exposed to type 1 interferons produced similar transcripts and ISG15 protein and conjugates. Laser-capture microdissection followed by proteomic analysis showed deficiency of titin in DM perifascicular atrophic myofibers. Interpretation A large-scale microarray study of muscle samples demonstrated that among a diverse group of muscle diseases DM was uniquely associated with upregulation of the ISG15 conjugation pathway. Exposure of human skeletal muscle cell culture to type 1 interferons produced a molecular picture highly similar to that seen in human DM muscle. Perifascicular atrophic myofibers in DM were deficient in a number of skeletal muscle proteins including titin. ANN NEUROL 2010;67:53,63 [source] PCI versus CABG for multivessel coronary disease in diabetics,CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 1 2009Giuseppe Tarantini MD Abstract Objectives: To explore the clinical performance of a strategy of revascularization by percutaneous coronary intervention (PCI) with drug-eluting stent (DES) in diabetic patients with multivessel disease (MVD) compared with coronary artery bypass graft (CABG), when it is based on clinical judgment. Background: Diabetes mellitus (DM) is a major risk factor for poor outcome after PCI. However, PCI may result in better outcome if the choice of revascularization (PCI versus CABG) is based on the physician decision, rather than randomization. Limited experiences have compared revascularization by DES-PCI versus CABG in DM patients with MVD. Methods: From August 2004 to August 2005, 220 consecutive DM patients with MVD underwent DES-PCI (93) or CABG (127) at our Institution. The type of revascularization was dependent on patient and/or physician choice. Major adverse cardiac and cerebrovascular events (MACCE) included death, myocardial infarction, repeat coronary revascularization, and stroke. Results: Compared with PCI patients, CABG patients had higher prevalence of 3-vessel disease (P < 0.001), significant LAD involvement (P < 0.001), presence of total occlusions (P = 0.04), collateral circulation (P < 0.001). At 2-year follow-up, MACCE were not different between CABG group and DES-PCI group (OR 1.2; P = 0.6) and, only when the clinical judgment on the revascularization choice was excluded at propensity analysis, DES-PCI increased the risk of 24-month MACCE in total population (OR 1.8; P = 0.04). Conclusions: For patients with DM and MVD, a clinical judgment-based revascularization by DES-PCI is not associated with worse 2-year outcome compared with CABG. © 2008 Wiley-Liss, Inc.
