Outcomes of ICU patients treated with intravenous immunoglobulin for sepsis or autoimmune diseases

Objectives: To evaluate the outcomes of hospitalized patients in two intensive care units (ICU) treated with intravenous immunoglobulin (IVIg) added to standard-of-care therapy. The indications for IVIg therapy were sepsis or autoimmune disease. Methods: We conducted a retrospective study involving adult patients with sepsis and autoimmune diseases, who received IVIg in the ICU at Wolfson and Sheba Medical Centers. A predefined chart was compiled on Excel to include a complete demographic collection, patient comorbidities, chronic medication use, disease severity scores (Charlson Comorbidity Index; SOFA and APACHE II index scores), indication and dosage of IVIg administration, duration of hospitalization and mortality rates. Results: Patients (n - 111) were divided into 2 groups: patients with sepsis only (n-67) and patients with autoimmune disease only (n-44). Septic patients had a shorter ICU stay, received IVIg early, and had reduced mortality if treated with high dose IVIg. Patients with autoimmune diseases did not have a favorable outcome despite IVIg treatment. In this group, IVIg was administered later than in the sepsis group. Conclusions: IVIg therapy improved the outcomes for ICU patients with sepsis.
