Abstract

To investigate the relationship between hyperuricemia and contrast-induced nephropathy (CIN) in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI). A total of 446 consecutive patients with CKD undergoing PCI in Guangdong general hospital were enrolled in this study. Patients were divided into hyperuricemic group (n = 205) and normouricemic group (n = 241).Hyperuricemia was defined as serum uric acid > 420 µmol/L for male, > 357 µmol/L for female. CIN was defined as ≥ 44.2 µmol/L or ≥ 25% increase from baseline Serum creatinine within 48-72 hours after contrast medium exposure, and that was not attributable to other causes.In hospital incidences of CIN and the major adverse cardiac events were compared between the two groups. The relationship between the incidence of CIN and hyperuricemia was evaluated by multivariate logistic regression analysis. CIN occurred in 16.6% (74/446) of patients, and incidence of CIN was significantly higher in the hyperuricemic group than in the normouricemic group [23.9% (49/446) vs. 10.4% (25/446) , P = 0.000]. Patients who developed CIN had higher in hospital mortality [14.9% (11/74) vs. 1.3% (5/372), P = 0.000]. Need for renal replacement therapy, acute...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
