Abstract:
BACKGROUND: The goal of this study is to define the relationship between the decreased renal function and anemia, and also to determine whether this relationship is different in male and female patients. METHODS: We conducted a retrospective study of 289 patients (male:female=157:132) who were followed at the department of internal medicine at Chonnam National University Hospital. General linear models were used to analyze the relationship between the hemoglobin concentration and Modification of Diet in the Renal Disease formula estimated Glomerular Filtration Rate (mL/min/1.73 m2). RESULTS: Among all patients, the mean hemoglobin concentration and hematocrit of the men with a Glomerular Filtration Rate of 50~59 mL/min/1.73 m2 was an absolute change of 0.8 g/dL (p=0.021) and it was 2.6% (p=0.011) lower than those of the patients with a Glomerular Filtration Rate> or =90 mL/min/1.73 m2 and continued to decrease further as the Glomerular Filtration Rate decreased, respectively (Hgb.: r=0.635, Hct.: r=0.640, all p<0.001). Among the male patients, the mean hemoglobin concentration and the hematocrit of men with a Glomerular Filtration Rate of 40~49 mL/min/1.73 m2 was an absolute change of 1.7 g/dL (p<0.01) and it was 4.4% (p<0.01) lower than those of the male patients with a Glomerular Filtration Rate> or =90 mL/min/1.73 m2 and continued to decrease as the Glomerular Filtration Rate decreased, respectively (Hgb.: r=0.698, Hct: r=0.689, all p<0.001). Among the female patients, the mean hemoglobin concentration with a Glomerular Filtration Rate of 60~69 mL/min/1.73 m2 was an absolute change of 0.9 g/dL (p<0.01) and the mean hematocrit was 2.8% (p<0.01) lower than those of the female patients with a Glomerular Filtration Rate> or =90 mL/min/1.73 m2 and continued to decrease further as the Glomerular Filtration Rate decreased, respectively (Hgb.: r=0.672, Hct.: r=0.687, all p<0.001). CONCLUSIONS: A decrease in the hemoglobin concentration was statistically significant in the patients of both genders, along with a moderately decreased Glomerular Filtration Rate (< or =60 mL/min/1.73 m2).
