The results indicate that 100 mg of iron saccharate often leads to transferrin oversaturation and the presence of catalytically active iron within 3.5 h after i.v. injection. As catalytically active iron is potentially toxic and may promote bacterial growth, it may be recommendable to use dosage regimens for i.v. iron that would not cause transferrin oversaturation.
The long-term survival of patients with acute renal failure is poor. Although survivors have a low health-related quality of life, they are as satisfied with their health as the general population.
The authors assessed hemostasis and fibrinolysis serially: on admission and on the 1st and 7th days after surgery for subarachnoid hemorrhage (SAH), examining the complications of aneurysm rupture and its surgical repair. Of 32 patients, 25 with SAH were compared with seven control patients who underwent surgery for an unruptured intracranial aneurysm. On admission, patients with SAH had higher thrombin-antithrombin III complex (TAT) levels (13.3 +/- 3.8 vs. 3.8 +/- 0.6 ng/ml, p = 0.01), fibrin degradation product, D-dimer levels (1310 +/- 220 vs. 556 +/- 89 ng/ml, p = 0.0001), and leukocyte counts (14.6 +/- 0.7 vs. 10.6 +/- 1.8 x 10(9) cells/L, p < 0.05) than did control patients. Postoperative D-dimer values (p = 0.007) remained higher in the SAH group. Furthermore, admission D-dimer levels were higher in the patients in poor clinical condition than in those in good condition (2017 +/- 377 vs. 934 +/- 208 ng/ml, p = 0.007), and D-dimer levels were associated with the outcome at 3 months after admission. Additionally, thrombin generation and fibrinolytic markers measured on admission were related to clinical grade, amount of subarachnoid blood seen on computerized tomography (CT) scanning, and patient fatality. Patients with hypodense lesions verified on follow-up CT scanning or with persistent neurological deficits at 3 months had higher prothrombin fragments 1 and 2, TAT, D-dimer, and plasminogen activator inhibitor-1 values on the 1st day postoperatively than did patients without such lesions. In short, in patients with SAH, activation of coagulation and fibrinolysis was strongly associated with clinical state, patient fatality, and outcome at 3 months, and postoperatively this activation correlated with the development of brain infarction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
