Background: Immunoadsorption (IAS) and therapeutic plasma exchange (TPE) are considered safe although fibrinogen is removed. To date no comparison of fibrinogen reduction and associated risk of bleeding in apheresis exists. Methods: Retrospective analysis of TPE, three IAS adsorbers, and combined TPE/IAS regarding fibrinogen reduction and bleeding incidence in 67 patients (1,032 treatments). Results: TPE and TPE/IAS reduced fibrinogen by 64 ± 11% and 58 ± 9%, leading to concentrations <100 mg/dl in 20 and 17% of treatments, respectively. IAS decreased fibrinogen less than TPE (26 ± 6%, p < 0.0001), resulting in fibrinogen concentrations <100 mg/dl in 1% of treatments. The processed volume correlated with reduction in TPE (r = 0.64, p < 0.01), but not in IAS. Bleeding occurred in 1.3% (IAS), 2.3% (TPE) and 3.1% (TPE/IAS) of treatments. Conclusion: Hypofibrinogenemia occurs in 20% of patients after TPE and TPE/IAS, but rarely after IAS. IAS removes fibrinogen independently of volume processed. Overall, bleeding is rare in apheresis.
We demonstrate that the innovative strategy of combining MF with semi-selective IA may substantially increase IgM elimination and affect classical complement activation. Our findings suggest that this new treatment concept could be an efficient strategy for recipient desensitization in ABO- and HLA-incompatible transplantation.
The incidence of hyperkalemia differed by less than 17% between groups. Use of balanced crystalloid resulted in less hyperchloremia and metabolic acidosis. Significantly more patients in the saline group required administration of catecholamines for circulatory support.
In ICU patients with diabetes, during a period of liberal glucose control, insulin administration, and among patients with hemoglobin A1c greater than or equal to 7%, the prevalence of hypoglycemia was reduced, without negatively affecting serum creatinine, the white cell count response, or other clinical outcomes.

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.
