Abstract:
Abstract BACKGROUND: Calcium dobesilate (calcium dihydroxy-2, 5-benzenesulfonate) has been widely used to treat chronic venous insufficiency and diabetic retinopathy, especialy many clinical studies showed that calcium dobesilate as vasoprotective compound ameliorates renal lesions in diabetic nephropathy. However, there are few literatures reported calcium dobesilate in the treatment of chronic renal alograft dysfunction after renal transplantation. OBJECTIVE:To observe the efficacy and safety of calcium dobesilate on chronic renal dysfunction after renal transplantation. METHODS:A total of 152 patients with chronic renal alograft dysfunction after renal transplantation were enroled from the Military Institute of Organ Transplantation, Changzheng Hospital, Second Military Medical University of Chinese PLA. They were randomly divided into the treatment group (n=78) and the control group (n=74). Patients in the treatment group received 500 mg of calcium dobesilate three times daily for eight weeks. Al patients were treated with calcineurin inhibitor-based triple immunosuppressive protocols and comprehensive therapies. RESULTS AND CONCLUSION: For patients receiving calcium dobesilate, serum creatinine, blood urea nitrogen and uric acid decreased significantly at two weeks after treatment and maintained a stable level (P < 0.05). However, serum creatinine and blood urea nitrogen returned to the original level soon after drug withdrawal. No significant difference was observed in blood cel count, liver function, blood lipids, electrolytes, blood pressure and 24-hour urine output between the two groups before and after therapy (P > 0.05). Administration of calcium dobesilate did not change the general condition of patients with renal insufficiency, nor did it affect blood concentrations of the immunosuppressive agents. Calcium dobesilate may help to delay the progress of graft injury in patients with chronic renal graft dysfunction by conjugating with creatinine, ameliorating the impaired microcirculation and its antioxidant property. The decline in serum creatinine aleviates patients’ anxiety and concern arising from the elevation of creatinine. However, the negative interference with serum creatinine caused by calcium dobesilate should be cautious in order to avoid misjudgment of patients’ condition.
