Meningococcal group A sepsis associated with rare manifestations and complicated by Kawasaki-like disease

An Unexpected Fever Post Serogroup B Meningococcal Sepsis

This case report describes an invasive meningococcal group B infection followed by the development of Kawasaki disease (KD) complicated by macrophage activation syndrome (MAS) in a 2-year-old child. The presented case indicates the possible etiologic relationship between meningococcal sepsis and KD as support of bacterial toxin induced theory. It's important to maintain a high grade of suspicious for KD in every relapse of fever also during convalescence phase of severe infection. Usually, initial treatment with intravenous immunoglobulin is sufficient to control the disease; but, in case of refractory KD complicated by MAS, corticosteroid therapy represents a good option inducing prompt fever resolution and clinical improvement.
