Infantile multisystem inflammatory disease: another case of a new syndrome
Insights
A rare inflammatory syndrome presents with chronic rash, enlarged head, and developmental delays. Elevated antibodies against Borrelia antigen suggest a potential infectious link in this new case.
Area of Science:
- Pediatrics
- Immunology
- Infectious Diseases
Background:
- This report details a rare inflammatory syndrome with neonatal onset.
- The syndrome is characterized by chronic urticarial rash, macrocephaly, proptosis, arthritis, and developmental delays.
Observation:
- A 4-year-old girl presented with a history of chronic diffuse urticarial rash since birth.
- Clinical manifestations included head enlargement, protruding eyeballs, bilateral knee arthritis, growth, and mental retardation.
- Laboratory findings revealed signs of chronic inflammation in blood and cerebrospinal fluid.
Findings:
- This case represents the 14th documented instance of this specific inflammatory syndrome.
- The etiology of this syndrome remains largely unknown.
- Significantly, this patient exhibited elevated antibody titers against Ixodes ricinus (I.ric.) Borrelia antigen in serum.
Implications:
- The discovery of elevated Borrelia antibodies suggests a potential infectious etiology for this rare syndrome.
- Further research is warranted to explore the role of Borrelia infection in pediatric inflammatory syndromes.
- This finding may guide future diagnostic approaches and therapeutic strategies for affected children.
Abstract:
A 4-year-old girl with neonatal onset of chronic diffuse urticarial rash, head enlargement, protruding eye balls, bilateral arthritis of the knees, growth and mental retardation, and signs in blood and cerebrospinal fluid of chronic inflammation is presented and compared to two similar cases reported by us previously. Including this new patient there are now 14 documented cases with this specific inflammatory syndrome whose aetiology remains unknown. In the present case, however, elevated antibody titres against I.ric. Borrelia antigen were found in the serum.
