Association of erythrocyte deformability with red blood cell distribution width in metabolic diseases and thalassemia trait.

Abstract Increased red blood distribution width (RDW) in anemia is related to disturbances in the cellular surface/volume ratio, usually accompanied by morphological alterations, while it has been shown in inflammatory diseases that the activity of pro-inflammatory cytokines disturbing erythropoiesis increases RDW. Recently it has been reported that higher RDW is related with decreased erythrocyte deformability, and that it could be related with the association of RDW and increased risk of cardiovascular diseases. In order to analyze the influence of morphological alterations and proinflammatory status on the relationship between RDW and erythrocyte deformability, we analyzed erythrocyte de…

Association of metabolic syndrome and its components with hyperuricemia in a Mediterranean population.

Several studies have found an association between hyperuricemia and metabolic syndrome (MS), although there are discrepancies as to which MS components play a pivotal role in this association. We aimed to investigate the association between serum uric acid (SUA) levels and MS in a Mediterranean population (eastern Spain). We performed a case-control study of 71 patients with MS and 122 healthy controls. MS was defined according to the revised National Cholesterol Education Program Adult Treatment Panel III modified criteria. Hyperuricemia was defined as SUA levels >6.55 mg/dL. We determined biochemical, lipidic and inflammatory parameters along with uric acid. Patients with MS showed a high…

Red blood cell distribution width is not related with inflammatory parameters in morbidly obese patients

Red blood cell distribution width (RDW) is a hematological parameter that has been studied in several clinical settings and has been found to be related to both anemia and inflammatory status. As obesity is related to increased inflammatory pattern, we aimed to analyze the RDW in this setting.We determined hematological and inflammatory parameters in morbidly obese patients before bariatric surgery (n=142) and normo-weight controls (n=144).RDW was higher in patients than in controls (p0.001), along with C-reactive protein (p0.001) and fibrinogen, (p0.001) while hemoglobin (p=0.026), serum iron (p0.001), MCH (p=0.002) and MCHC (p0.001) were lower in morbidly obese patients. The logistic corr…

Homocysteine levels in morbidly obese patients: its association with waist circumference and insulin resistance.

The association between morbid obesity and hyperhomocysteinemia (HH) remains controversial and the nature of this relationship needs to be clarified as several metabolic, lipidic, inflammatory and anthropometric alterations that accompany morbid obesity may be involved. In 66 morbidly obese patients, 47 women and 19 men aged 41 ± 12 years and 66 normo-weight subjects, 43 women and 23 men, aged 45 ± 11 years, we determined homocysteine (Hcy) levels along with lipidic, anthropometric, inflammatory and insulin resistance markers. In addition, we investigated the effect of Metabolic Syndrome (MS) and its components on Hcy levels. Obese patients had statistically higher Hcy levels than controls:…

Reply to "The association of red blood cell distribution width and morbid obesity" by Aydin et al.

We thank Aydin & cols. for their comments about our recently published paper “Red blood cell distribution width is not related with inflammatory parameters in morbidly obese patients” in Clinical Biochemistry Journal [1]. The authors show their concern about the clinical interpretation of our findings since we did not report folate and B12 vitamin levels. Moreover, they state that we should demonstrate the elimination of thrombocytopenic diseases by showing platelet count data. Aswe state in the paper, exclusion criteria for obese patients included “organic, malignant, hematological, infectious or inflammatory disease”. Therefore, any case of thrombocytopenic disease was not included. Moreo…
