Background and Objectives. Nailfold capillaroscopy is an easy and noninvasive technique used to investigate dermal microvasculature. Traditional investigations of vascularity do not detect changes until they are well-established in type 2 diabetics. The objective of the current study was to evaluate nailfold capillaries in type 2 diabetes mellitus patients and to determine the association of retinopathy with changes in the nailfold capillaries. Materials and Methods. Capillaroscopic findings by nailfold capillaroscopy and fundoscopic examinations were assessed in 216 patients with type 2 diabetes mellitus and 101 healthy controls included in this prospective study. Results. Retinopathy was detected in 43.05% of diabetic patients (n = 93). Capillaroscopic findings including tortuosity (p < 0.001), bushy capillary (p < 0.001), neoformation (p < 0.001), bizarre capillary (p < 0.001), microhemorrhage (p = 0.001), capillary ectasia (p = 0.002), and aneurysm (p = 0.004) were significantly higher in diabetic group than control group. In logistic regression analysis, only tortuosity was shown significant (OR, 2.16; p = 0.036). There was also a significant relation between diabetes duration and most of the capillaroscopic findings. Conclusion. Capillaroscopic changes were found to be correlated with diabetic retinopathy, in particular with longer disease duration in our study. Capillaroscopic imaging could be a useful new technique for assessment of diabetic microvascular changes.
Our findings revealed that lower FT3 levels and older age predict the likelihood of developing GDM in euthyroid pregnant women, with no influence of other thyroid hormones or blood counts on the risk of GDM.
Context:Impact of gestational diabetes mellitus (GDM) on the coagulation system, dynamics involved at a pathophysiological level and the exact mechanism remain unclear.Aims:To evaluate the association between diabetes-related parameters and hemostatic factors to search for a tendency of thrombosis in GDM.Settings and Design:Nineteen pregnant women who had GDM, 16 healthy pregnant and 13 healthy nonpregnant controls admitted to the Endocrinology outpatient clinics were enrolled in the study.Subjects and Methods:Fasting and postprandial glucose, hemoglobin A1c and insulin levels, and insulin resistance; fructosamine, thrombin activatable fibrinolysis inhibitor (TAFI), tissue factor pathway inhibitor (TFPI), plasminogen activator inhibitor Type-1 (PAI-1), tissue-type plasminogen activator (t-PA), fibrinogen, plasminogen and hemoglobin levels, platelet counts, prothrombin time (PT), and activated partial thromboplastin time (aPTT) were studied.Statistical Analysis Used:One-way analysis of variance, Kruskal–Wallis, and post hoc Tukey honestly significant difference or Conover's nonparametric multiple comparison tests for comparison of the study groups.Results:PT and aPTT were significantly lower in GDM patients compared to controls (P < 0.05), whereas fibrinogen and plasminogen levels were significantly higher in this group compared to both nonpregnant and healthy pregnant controls (P < 0.05 for each). TAFI, TFPI, PAI-1, and tissue t-PA levels were not significantly different among groups.Conclusions:Our findings indicate tendency to develop thrombosis in GDM similar to diabetes mellitus; but more comprehensive studies with larger sample size are needed to determine the relationship between GDM and hemostasis.
Background/Aims: Several studies have shown that a change in microbiota plays an important role in the pathogenesis of inflammatory bowel disease (IBD). Furthermore, with the emergence in recent studies of differences according to the subtype of IBD and whether the disease is active or in remission, there has started to be research into the relationship between IBD and several microorganisms. Blastocystis hominis is primary among these organisms. The aim of the present study was to determine the role of B. hominis in the acute flare-up of ulcerative colitis (UC). Materials and Methods: A total of 114 patients with UC were included in the study, with 52 in the active phase. The Mayo scoring system was used for the activity index. Patients determined with a flare-up agent other than B. hominis were excluded from the study. Fecal samples of the patients were examined by the polymerase chain reaction method for the presence of B. hominis. Results: B. hominis positivity was determined in 37 (34%) patients with UC. Of the patients, 17 (32.6%) were in the acute flare-up phase, and 20 (32.2%) were in remission (p=0.961). In 11 (64.7%) of the B. hominis positive patients, the disease severity was determined as mild-moderate (p<0.001). Conclusion: The results of the present study showed that while there was no difference between the active and remission phases in respect of B. hominis presence, there was milder involvement in those determined with B. hominis.
The activation of the platelets plays a key role in the formation of thrombosis. The variables such as mean platelet volume, platelet factor 4 and β-thromboglobulin have been used in the demonstration of the platelet activation. However, when the literature was reviewed, there was not found any study investigating the level of β-thromboglobulin in patients with rheumatoid arthritis. Our goal is to evaluate the β-thromboglobulin levels together with mean platelet volume in patients with arthritis. This study is a clinical study which has a control group that has been designed prospectively, and in this study, Rheumatology Outpatient Clinic follow-up patients with rheumatoid arthritis and healthy control group were studied. All patients and healthy volunteers were examined β-thromboglobulin and mean platelet volume. Twenty-two patients with rheumatoid arthritis and 21 healthy volunteers participated in the study. β-Thromboglobulin mean was found as 98.00 ± 60.49 ng/mL in rheumatoid arthritis group and it was 62.38 ± 30.41 ng/mL in healthy control group. The differences between these groups were significant in terms of the levels of β-thromboglobulin (p = 0.02). We found significant differences between the groups in terms of mean platelet volume (p = 0.049). In this study, the level of β-thromboglobulin was found significantly higher in patients with rheumatoid arthritis, which is a chronic inflammatory disease. This result could be an indicator, such as platelet activation in patients with rheumatoid arthritis, or it may be a helper marker in the follow-up and treatment of developing cardiovascular risk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
