Is There Any Relationship Between Extra-Pulmonary Manifestations of Mycoplasma Pneumoniae Infection and Atopy/Respiratory Allergy in Children?

Abstract

Mycoplasma pneumoniae is a common cause of respiratory infections in children, but sometimes extra-pulmonary diseases can be observed. The immunological mechanisms involved in these extra-respiratory complications are unknown. Here, we report a small case series of Mycoplasma-related diseases including 5 children who developed: i) aseptic meningitis; ii) urticarial rash and pericardial effusion; iii) pleural effusion with severe eosinophilia; iv) Stevens-Johnson syndrome; v) multiform erythema. Interestingly, all children were moderately to highly atopic, as a common immunologic feature.
