Abstract:

BACKGROUND: Recent studies have shown that anemia after renal transplantation is an important risk factor for cardiovascular disease after transplantation, as well as the independent predictor of death.

OBJECTIVE: To explore the prevalence, processing and risk factors of anemia after renal transplantation.

METHODS: The data of 154 cases renal transplantation recipients who followed-up in the Department of Urology, Fuzhou General Hospital of Nanjing Military Command were retrospectively analyzed. The blood routine and blood biochemistry of the renal transplantation patients were collected for analysis during hospitalization and 1, 2, 3, 4 and 5 years after transplantation.

RESULTS AND CONCLUSION: The prevalence of anemia during transplantation and the subsequent 5 years after transplantation were 45.5%, 10.7%, 9.6%, 14.8%, 13.5% and 19.6%, respectively. Patients had anemia at least once in five years, and 42% of the patients experienced recurrence. Relative analysis showed that hemoglobin levels were associated with function of transplanted kidney. Different genders, ages and the using of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers or not has no correlation with the prevalence of anemia. Binary Logistic regression analysis showed that serum creatinine and blood urea nitrogen levels at 1 year after transplantation were correlated with the diagnosis of anemia, and only associated with serum creatinine level at 5 years after transplantation. Iron drug is relatively common, but erythropoietin is rarely applied in the anemia patients with transplant renal insufficiency. The prevalence of anemia after renal transplantation is high, and transplant renal insufficiency is a major risk factor for the disease.
