Abstract

PURPOSE:

Intravenous immunoglobulin (IVIG) has been proposed as an adjunctive therapy for sepsis. Related systematic reviews and meta-analyses of IVIG in sepsis indicate that IVIG can reduce the mortality of sepsis in adults. However, the effective dose of IVIG has not been clearly determined to date. We aimed to conduct an updated meta-analysis and use a network meta-analysis to elucidate the efficacy of IVIG dosing regimens in sepsis treatment.

METHODS:

We searched PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE for articles published on or before February 14, 2019. We performed a direct meta-analysis to update a previous meta-analysis of the effects of IVIG therapy on mortality in adult patients with septic shock and a network meta-analysis to evaluate the efficacy of IVIG dosing regimens in sepsis treatment.

FINDINGS:

Compared with the control treatment, the IVIG treatment reduced the all-cause mortality of patients with sepsis (odds ratio = 0.61; 95% CI, 0.41-0.92; P = 0.018), but significant heterogeneity was found across the studies (I2 = 45.0%; P = 0.04). Regarding the IVIG dosage regimens, the highest total dose range (1.5-2 g/kg) was the optimal dose of administration (surface under the cumulative ranking curve = 84.7%).

IMPLICATIONS:

On the basis of the available data, IVIG treatment is likely to reduce the all-cause mortality of patients with sepsis, and the highest total dose range (1.5-2 g/kg) is likely the optimal dose of administration.
