BACKGROUND Pityriasis rosea (PR) is an inflammatory skin disorder of unknown etiology. However, it is suggested to be related with the reactivation of human herpes virus 7 (HHV-7) and/or HHV-6. It is sometimes diffucult to distinguish PR from PR-like drug eruptions and other inflammatory disorders, so we need new parameters which are cheap and easy in determining PR. Red blood cell distribution...

BACKGROUND In upper gastrointestinal bleeding (UGIB) patients, early risk stratification allows appropriate therapy that may be helpful for reducing morbidity and mortality. OBJECTIVES to evaluate the efficacy of red-cell distribution width (RDW) for prediction of high-risk in UGIB patients. METHODS We conducted a clinical retrospective observational study based on data for UGIB patients fr...

BACKGROUND Increased red cell distribution width (RDW) has been related to poor prognosis in patients with cardiovascular disease, and is a predictor of cardiovascular mortality in the general population. The purpose of the present study was to investigate if RDW is associated with increased incidence of stroke and its subtypes in individuals from the general population. METHODS Red cell dist...

INTRODUCTION Recently, it has been suggested an association between red cell distribution width (RDW) and Crohn's disease activity index (CDAI), but its use is not yet performed in daily clinical practice. OBJECTIVES To determine whether RDW can be used as a marker of Crohn's disease (CD) activity. METHODS This was a cross-sectional study including patients with CD, observed consecutively i...

The present study compared short- and long-term prognostic values of red blood cell distribution width (RDW) with those of hemoglobin (Hgb) among patients with acute congestive heart failure (CHF) in a cardiac care unit. The cross-sectional study examined data from 521 patients with acute CHF who were admitted to a cardiac care unit and followed up for 24 months (median). Mean Hgb levels in pat...

BACKGROUND Cardiac syndrome X (CSX) is a condition characterized by chest pain with normal coronary arteries. However, its pathogenesis has not fully been understood yet. Red blood cell distribution width (RDW) has recently been suggested as a marker of acute and chronic cardiovascular diseases, while no data is available in patients with CSX. METHODS One hundred and twenty consecutive patien...

Nasal polyposis represents as a chronic hyperplastic sinusitis associated with chronic inflammation. In present retrospective study, we aimed to compare the Mean Platelet Volume (MPV), Red Cell Distribution Width (RDW) and Neutrophil to Lymphocyte Ratio (NLR) values of patients with nasal polyposis to those in healthy subjects. We included 35 nasal polyp patients and 45 healthy subjects into th...

Aims: We aimed to observe the correlation between Red Cell Distribution Width (RDW) and acute attack of Chronic Obstructive Pulmonary Disease (COPD). Methods: Patients at acute attack of COPD included to the study as study group. Control group is included subjects with stable COPD. Hemogram parameters obtained from database of the institution and analysed. Results: 42 patients at acute attack o...

The aim of this study was to examine the effect of thyroxine on ovulation in immature rdw rats and the fertilization and development of the eggs. Serum thyroxine concentrations at 30 days of age were significantly lower in rdw rats than in normal rats (P < 0.001), and greatly increased after thyroxine replacement therapy (P < 0.001). Although few eggs (1-5 +/- 1-2) were obtained from immature r...

We applaud the work by Kemal et al., in their well-presented article. The authors found lower mean platelet volume (MPV) and red blood cell distribution (RDW) levels in epistaxis. It is worth noting that any process resulting in the release of immature erythrocyte/platelet or increased destruction of red blood cell/platelet will change the levels of RDW/MPV. Moreover, it has been reported that ...
