Increased Red Blood Cell Volume Distribution Width: Important Clinical Implications in Predicting Gastric Diseases
Background:
The red blood cell distribution width (RDW) is a blood analyzer marker showing the peripheral blood erythrocyte volume heterogeneity parameters. It is a normal diagnosis index of many diseases. This study was performed to evaluate the relationship between the RDW and gastric diseases.
Methods:
A total of 189 patients with GC, 68 patients with gastric ulcers, 92 patients with chronic gastritis, and 157 healthy controls were enrolled in this study. Each patient's RDW and other biomarkers were recorded. All of the statistical analyses and comparisons between each group were determined using SPSS16.0 software. The statistical significance level was set to a p-value < 0.05.
Results:
The RDW was significantly higher in those patients with gastric diseases when compared to the control group (p < 0.05). In addition, the RDW was independently correlated with the presence of GC and gastric ulcers. Significantly positive correlations between the RDW, platelets, and platelet distribution width (PDW) were observed in those patients with GC and gastric ulcers, although there were negative correlations with the red blood cells (RBCs), hemoglobin, and mean corpuscular volume (MCV) (p < 0.05). In the chronic gastritis group, elevated RDW values were closely associated with the hemoglobin, platelet, and MCV values (p < 0.05). The specificities of the gastric diseases groups were greater than 90%.
Conclusions:
In cases of gastric diseases, the RDW values were increased and were associated with several laboratory parameters. These finding may have important clinical implications in predicting gastric diseases.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
