Is Kidney Injury Molecule 1 a Valuable Tool for the Early Diagnosis of Contrast-Induced Nephropathy?

Aim/scope: Contrast-induced nephropathy (CIN) is a common complication of diagnostic/therapeutic procedures. Serum creatinine levels are sensitive but often lead to diagnostic delays in acute kidney injury and potential misclassification of actual injury status. Kidney injury molecule (KIM-1) is a novel early marker of acute kidney injury.

Association of Glomerular Filtration Rate with Inflammation in Polycystic Ovary Syndrome.

Background: We aimed to estimate the glomerular filtration rate (GFR) in women with polycystic ovary syndrome (PCOS) and to determine the relationship between GFR with C-reactive protein (CRP) and uric acid.

Materials And Methods: In this cross-sectional study, one-hundred and forty PCOS women and 60 healthy subjects were evaluated. The study was carried out at Endocrinol- ogy Outpatient Clinic, Erzurum Training and Research Hospital, Erzurum, Turkey, from December 2010 to January 2011.

Matrix Metalloproteinases 2 and 9 Polymorphism in Patients With Myeloproliferative Diseases: A STROBE-Compliant Observational Study.

Chronic myeloproliferative disorders such as polycythemia vera (PV), essential thrombocytosis (ET), and idiopathic myelofibrosis arise from clonal proliferation of neoplastic stem cells in the bone marrow. Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that have potential to degrade all types of extracellular matrix (ECM) and also play a role in remodeling of the ECM. It is known that MMPs play a role in bone marrow remodeling.

Plasma nesfatin-1 levels are increased in patients with polycystic ovary syndrome.

Background: Nesfatin-1 is a recently discovered neuropeptide derived from its precursor nucleobindin-2 (NUCB2) and has been implicated in the regulation of feeding and energy metabolism. It is located in the brain and also produced at the periphery and present in the plasma. However, its pathophysiological role in humans remains unknown.

Fibromyalgia in patients with other rheumatic diseases: prevalence and relationship with disease activity.

Fibromyalgia (FM) is a syndrome characterized by chronic widespread pain and the presence of specific tender points. The prevalence of FM has been estimated at 2-7 % of the general global population. The presence of FM in several rheumatic diseases with a structural pathology has been reported as 11-30 %.

Higher thrombin activatable fibrinolysis inhibitor levels are associated with inflammation in attack-free familial Mediterranean fever patients.

Background: Coagulation abnormalities have been reported in familial Mediterranean fever (FMF) patients with amyloidosis and nephrotic syndrome; but there is not enough data about the continuity of the thrombogenic activity in FMF patients in clinical remission. The purpose of this study was to assess thrombin activatable fibrinolysis inhibitor (TAFI) levels and its relationship with fibrinolytic activity and also evaluate relationships between mutations and clinical signs in attack-free patients without amyloidosis.

Methods: Seventy-nine FMF patients and 40 healthy adults were included.

Effect of ethinyl estradiol-cyproterone acetate treatment on asymmetric dimethyl-arginine levels in women with polycystic ovary syndrome.

Purpose: Our study was undertaken to evaluate the levels of asymmetric dimethyl-arginine (ADMA) in a group of patients affected with polycystic ovary syndrome (PCOS)--under ethinyl estradiol-cyproterone acetate treatment or not--as compared with a group of healthy controls.

Methods: Fifty-eight women with PCOS and 45 patients as control group were included in the study. The 58 women with PCOS were separated into two groups: Group A (n = 29) were treated with an oral contraceptive pill containing 0.

Relationship between some clinical situations, autoantibodies, and pseudothrombocytopenia.

The widespread usage of blood count autoanalyzers has led to a major improvement in cellular hematology because of quick and accurate results found in most instances. However, spurious test results also can be observed like pseudothrombocytopenia (PTCP). In our study, we aimed to evaluate the clinical and laboratory factors associated with PTCP.

Thrombopoietin and mean platelet volume in patients with ischemic stroke.

Objective: The aim of this study was to evaluate mean platelet volume (MPV), thrombopoietin (TPO), and platelet levels in patients with ischemic stroke and compare this with healthy controls.

Methods: We prospectively studied 50 patients with ischemic stroke and compared them with 37 control participants who have evaluated in internal medicine polyclinic and had no history of cerebrovascular events. All patients were within 24 hours after stroke; MPV and TPO were measured on admission.

Serum thrombopoietin levels in patients with non-alcoholic fatty liver disease.

Objective: To observe thrombopoietin (TPO) levels in patients with non-alcoholic fatty liver disease (NAFLD).

Methods: The study was performed between November 2010 and March 2011 at the Department of Internal Medicine, Faculty of Medicine, Fatih University, Ankara, Turkey. A total of 60 consecutive patients with ultrasound proven NAFLD (study group), and 28 healthy volunteers (control study) were included in the study.

Heparin platelet factor 4 antibody positivity in pseudothrombocytopenia.

Pseudothrombocytopenia (PTCP) is a laboratory event of platelet clustering related to drugs used for anticoagulation. This condition is engendered by autoantibodies against platelets in usually EDTA-anticoagulated blood. Pseudothrombocytopenia has no clinical significance but when evaluated as true thrombocytopenia, this misconception may lead to unnecessary diagnostic procedures.
