Risk factors for depression and anxiety in painful and painless diabetic polyneuropathy: A multicentre observational cross-sectional study.

Background: Despite the high prevalence of depression and anxiety in chronic pain conditions, current knowledge concerning emotional distress among painful diabetic polyneuropathy (pDSPN) and other diabetes mellitus (DM) sufferers is limited.

Methods: This observational multicentre cohort study employed the Hospital Anxiety and Depression Scale, the Beck Depression Inventory II and the State-Trait Anxiety Inventory to assess symptoms of depression and anxiety in several groups with diabetes, as well as in a control group. The study cohort included 347 pDSPN patients aged 63.

Sensory phenotype and risk factors for painful diabetic neuropathy: a cross-sectional observational study.

Different sensory profiles in diabetic distal symmetrical sensory-motor polyneuropathy (DSPN) may be associated with pain and the responsiveness to analgesia. We aimed to characterize sensory phenotypes of patients with painful and painless diabetic neuropathy and to assess demographic, clinical, metabolic, and electrophysiological parameters related to the presence of neuropathic pain in a large cohort of well-defined DSPN subjects. This observational cross-sectional multi-center cohort study (performed as part of the ncRNAPain EU consortium) of 232 subjects with nonpainful (n = 74) and painful (n = 158) DSPN associated with diabetes mellitus of type 1 and 2 (median age 63 years, range 21-87 years; 92 women) comprised detailed history taking, laboratory tests, neurological examination, quantitative sensory testing, nerve conduction studies, and neuropathy severity scores.

[Pregnancy outcomes in women with gestational diabetes: specific subgroups might require increased attention].

Objectives: To compare peri-partal parameters between two groups of pregnant women - with and without gestational diabetes mellitus (GDM), to correlate degree of glucose abnormality with incidence of peri-partal morbidity and, finally, to analyse the potential effect of comorbidities (i.e. obesity, hypertension, thyreopathy, polycystic ovary syndrome, trombophylia, anemia, allergy, smoking) on pregnancy outcomes.

[Pregestional diabetes mellitus and pregnancy].

There is a groving number of women with pregestational diabetes mellitus. Additionaly, nowadays therapy of diabetes mellitus type I allows gravidity even in patients in whom diabetes manifested itself during their early childhood. Presence of chronic complications of diabetes increases risk of complications during pregnancy.

Differences in food intake and genetic variability in taste receptors between Czech pregnant women with and without gestational diabetes mellitus.

Purpose: Gestational diabetes mellitus (GDM) represents the most frequent metabolic disorder in pregnancy. Since dietary intake plays an important role in obesity and type 2 diabetes development, it is likely to be for the susceptibility to GDM too. Food preferences, driving partly the diet composition, are changing during pregnancy.

Hyperuricemia contributes to the faster progression of diabetic kidney disease in type 2 diabetes mellitus.

Aims: The aims of the study were (i) to ascertain prognostic value of serum uric acid (SUA) for diabetic kidney disease (DKD) progression and major adverse cardiovascular event (MACE) in a cohort of T2DM patients, (ii) to ascertain eventual protective effect of allopurinol treatment, (iii) to determine the effect of genetic variability in UA transporters on DKD progression, and (iv) to define optimal cut-off values for SUA in patients with DKD.

Methods: Study comprised 422 subjects with diabetes duration at least 15years followed-up for a median of 43 [IQR 22-77] months. Participants were categorized into stable or progressors according to their change in albuminuria or chronic kidney disease (CKD) stage.

Dysfunctional protection against advanced glycation due to thiamine metabolism abnormalities in gestational diabetes.

While the pathogenic role of dicarbonyl stress and accelerated formation of advanced glycation end products (AGEs) to glucose intolerance and to the development of diabetic complications is well established, little is known about these processes in gestational diabetes mellitus (GDM), a condition pathogenically quite similar to type 2 diabetes. The aims of the present study were (i) to determine plasma thiamine and erythrocyte thiamine diphosphate (TDP) and transketolase (TKT) activity in pregnant women with and without GDM, (ii) to assess relationships between thiamine metabolism parameters and selected clinical, biochemical and anthropometric characteristics and, finally, (iii) to analyse relationship between variability in the genes involved in the regulation of transmembrane thiamine transport (i.e.

Resting Heart Rate Does Not Predict Cardiovascular and Renal Outcomes in Type 2 Diabetic Patients.

Elevated resting heart rate (RHR) has been associated with increased risk of mortality and cardiovascular events. Limited data are available so far in type 2 diabetic (T2DM) subjects with no study focusing on progressive renal decline specifically. Aims of our study were to verify RHR as a simple and reliable predictor of adverse disease outcomes in T2DM patients.

Serum carboxymethyl-lysine, a dominant advanced glycation end product, is increased in women with gestational diabetes mellitus.

Aims: The objective of the study was to measure one of the circulating Advanced Glycation End Products (AGEs) - Nε-(carboxymethyl)lysine (CML) - in a case-control study (n = 307) of pregnant women with gestational diabetes mellitus (GDM) and physiological pregnancies and to ascertain the factors contributing to CML levels and the potential relevance of CML for selected perinatal and postpartum outcomes.

Methods: All subjects underwent oGTT between 24th and 30th week of gestation and GDM was diagnosed according to WHO criteria. CML was determined by ELISA using commercial kit.

Possibility to predict early postpartum glucose abnormality following gestational diabetes mellitus based on the results of routine mid-gestational screening.

Introduction: Women with previous gestational diabetes mellitus (GDM) have increased risk of developing glucose abnormality, but current diagnostic criteria are evidence-based for adverse pregnancy outcome.

The Aims Of Our Study Were: (i) to ascertain a frequency of early conversion of GDM into permanent glucose abnormality, (ii) to determine predictive potential of current GDM diagnostic criteria for prediction of postpartum glucose abnormality and (iii) to find optimal cut-off values of oral glucose tolerance test (oGTT) to stratify GDM population according to postpartum risk.

Materials And Methods: Electronic medical records of an ethnically homogenous cohort of women diagnosed and treated for GDM in a single medical centre during the period 2005-2011 who completed postpartum oGTT up to 1 year after the index delivery were retrospectively analysed (N=305).

Vitamin D Status in Women with Gestational Diabetes Mellitus during Pregnancy and Postpartum.

Of many vitamin D extraskeletal functions, its modulatory role in insulin secretion and action is especially relevant for gestational diabetes mellitus (GDM). The aims of the present study were to determine midgestational and early postpartum vitamin D status in pregnant women with and without GDM and to describe the relationship between midgestational and postpartum vitamin D status and parallel changes of glucose tolerance. A total of 76 pregnant women (47 GDM and 29 healthy controls) were included in the study.

Genetic variability in enzymes of metabolic pathways conferring protection against non-enzymatic glycation versus diabetes-related morbidity and mortality.

Background: We hypothesized that genetic variability in genes encoding enzymes metabolizing glycolytic intermediates produced in excess under hyperglycemic conditions [i.e., transketolase (TKT), transaldolase, TKT-like protein 1, fructosamine 3-kinase (FN3K), glyoxalase 1 and glucose-6-phosphate dehydrogenase] could influence progression of diabetic nephropathy (DN) and diabetes-related morbidity and mortality.

ADMA, SDMA and L-arginine/ADMA ratio but not DDAH genetic polymorphisms are reliable predictors of diabetic nephropathy progression as identified by competing risk analysis.

Background/aims: Complex interplay of genetic and (patho)physiological factors influence availability of nitric oxide during the development and progression of diabetic complications. We assessed predictive value of commonly studied methylated asymmetric and symmetric dimethylarginines (ADMA and SDMA) and selected single nucleotide polymorphisms (SNPs) in dimethylarginine dimethylaminohydrolase (DDAH) 1 and 2 genes for the progression of diabetic nephropathy (DN).

Methods: A total of 341 type 1 and type 2 diabetes patients with variable degree of kidney disease were included at baseline.

Prediabetes/early diabetes-associated neuropathy predominantly involves sensory small fibres.

The aim of this study was to investigate the characteristics of prediabetes (preDM) and early (<3 years) diabetes mellitus type 2 (eDM2)-associated neuropathy and the value of recently proposed diagnostic criteria for diabetic sensorimotor polyneuropathy (DSPN). A prospective case-control study in a group of 48 consecutive patients with eDM2, 16 preDM patients and 40 age- and sex-matched normoglycaemic controls was performed. Clinical and laboratory diagnostic tests were used to detect neuropathic abnormalities; these were further classified in terms of recent diagnostic criteria.

Expression of growth-associated protein 43 in the skin nerve fibers of patients with type 2 diabetes mellitus.

The growth-associated protein 43 (GAP-43) is known as a marker of regenerating nerve fibers and their continuous remodeling in the adult human skin. The purpose of this pilot study was to investigate a possible role for GAP-43 in the detection of the early stages of small-fiber neuropathy in patients with type 2 diabetes mellitus (DM2) as compared with a well- established and validated parameter - intra-epidermal nerve fiber density (IENFD) of protein gene product 9.5 (PGP 9.

[Pancreatic cancer--association with diabetes mellitus and smoking].

Introduction: Pancreatic cancer is a disease with rather poor prognosis. This can be explained, among other reasons, by unusually aggressive course of the tumour growth and, in the majority of cases, late, and thus further treatment limiting, diagnosis. In addition, no effective screening programme for pancreatic cancer is available and thus identification of risk factors associated with the development of pancreatic cancer represents a possible approach to diagnosing early stages of the disease.

Role of thiamine status and genetic variability in transketolase and other pentose phosphate cycle enzymes in the progression of diabetic nephropathy.

Background: Pentose phosphate pathway (PPP) represents a potentially 'protective' mechanism in hyperglycaemia due to shunting of glycolytic intermediates into PPP reactions. We hypothesized that thiamine status (plasma and erythrocyte levels of thiamine and its esters) together with genetic variability in key PPP enzymes-transketolase (TKT), transaldolase and TKT-like-might contribute to the progression of diabetic nephropathy (DN) and mortality of diabetics.

Methods: A total of 240 diabetic subjects with variable degree of kidney disease were included at baseline and were followed up for a median of 26 (IQR 21-50) months.

Numerical defects in CD8+CD28- T-suppressor lymphocyte population in patients with type 1 diabetes mellitus and multiple sclerosis.

Type 1 diabetes mellitus (T1D) and multiple sclerosis (MS) are organ-specific autoimmune diseases leading to an attack of auto-aggressive lymphocytes against the pancreatic beta-cells and central nervous system, respectively. Using four-colour flow cytometry, T-lymphocyte populations having an important function in autoimmune processes were analyzed. T-regulatory cells (Treg) CD4(+)CD25(+)CD127(low), T-suppressor cells (Ts) CD8(+)CD28(-), activated helper CD4(+)CD25(+)CD127(+) and cytotoxic CD8(+)CD25(+) T-cells and also naive CD4(+)CD45RA(+) and memory T-cells CD4(+)CD45RO(+) were compared in the group of patients with T1D (n=30), MS (n=31) and in the group of healthy controls (n=29).

Etiology of small-fiber neuropathy.

The aim of this study was to evaluate the etiology in a group of 84 patients with painful sensory neuropathy with predominant small-fiber dysfunction (54 men and 30 women, median: 58; range: 25-83 years) recruited from a population of the South Moravian region of the Czech Republic. Involvement of small nerve fibers was verified by abnormal thermal thresholds and/or reduced intraepidermal nerve fiber densities. Motor signs or symptoms or significant clinical signs of sensory large-fiber involvement were exclusionary; 33 patients, however, had sensory nerve conduction abnormalities.

Small-fibre involvement in diabetic patients with neuropathic foot pain.

Aims: To assess small-fibre involvement in diabetic patients with neuropathic pain.

Methods: Peripheral nerve function was assessed in 30 patients with Type 2 diabetes mellitus (T2DM, n = 24) or impaired glucose tolerance (IGT, n = 6), and clinical symptoms of neuropathic pain in the feet, using nerve conduction studies, autonomic tests, thermal quantitative sensory testing (T-QST) and quantification of intra- and subepidermal nerve fibre densities in skin punch biopsies.

Results: Clinical signs of isolated small-fibre sensory involvement were present in 13 patients [pure small-fibre neuropathy (pSFN)], seven patients had isolated positive sensory symptoms without neurological deficits (pSFN-).

[The heart in diabetics].

Macrovascular complications in diabetics create a high risk for cardiovascular disease (CVD). Generally, the main risk factors for CVD include age, men's sex, elevated LDL-cholesterol and reduced HDL-cholesterol, elevated fibrinogen, hypertension, smoking, and diabetes mellitus. Clinical manifestation of coronary disease is determined by number, area, and severity of coronary stenoses, myocardial function, and presence of induced ischemia.
