Abstract

How dialysis affects the survival of patients with biopsy-proven IgA nephropathy (IgAN) is not fully understood. The present long-term cohort study quantifies the survival rates and incidence of cardio-cerebrovascular diseases (CCVDs) among such patients in Japan. Fifty-two of 433 patients with IgAN who had reached end-stage kidney disease underwent renal replacement therapy (RRT) between 1981 and 2010. The overall survival rate and incidence of CCVDs in these patients were evaluated during follow-up for 11.3 ± 6.4 years. The mean age at starting RRT was 42.8 ± 13.3 years. Only seven patients died during follow-up (mortality rate, 1.2/100 person-years) and Kaplan-Meier analysis revealed favorable survival rates of 93.3% and 65.1% at 10 and 20 years, respectively, compared with that of patients with glomerulonephritis in the registry of the Japanese Society for Dialysis Therapy who required RRT. Malignancy and CCVDs were causes of death at 13.6 ± 4.8 and 3.9 ± 1.3 years, respectively, after starting RRT. Fatal and non-fatal CCVDs developed in 15 (incidence, 2.7/100 person-years) patients and acute coronary syndrome and cerebral hemorrhage developed relatively soon after starting RRT. Cox proportional hazards models revealed that...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
