Conclusion
Privigen might have a lower rate of IVIG resistance and reduced coronary artery involvement. This discrepancy might due to the concentration, the stabilizer, or the source of plasma, all of which serve to minimize IgG dimer aggregation and provide a higher proportion of IgG1 to interact with Fc gamma receptors as Fig. Based on our study's findings, we have concluded that Privigen may exhibit a lower incidence of IVIG resistance and reduced coronary artery involvement. This disparity may be attributed to the presence of
