UNLABELLED: This study reports the first paediatric case of acute inflammatory demyelinating polyradiculoneuropathy (AIDP) associated with a fatal haemophagocytic lymphohistiocytosis (HLH). The patient developed progressive weakness of the lower limbs in the context of a picture of infectious mononucleosis and Epstein-Barr virus (EBV) infection. After an apparent improvement, a fulminant hepatic failure and pancytopenia ensued, leading to death. Molecular genetic studies documented a compound heterozygosity for two mutations in the perforin (PRF1) gene as the background defect for a familial haemophagocytic lymphohistiocytosis (FHL).
CONCLUSION: In this patient EBV infection triggered both AIDP and FHL. The latter condition was due to PRF1 deficiency. Two novel mutations in the PRF1 gene were concomitantly present in the patient. The first caused an amino acid change, while the second introduced a stop codon in the sequence which resulted in a truncated protein.
