Acute disseminated encephalomyelitis risk factors
Introduction
Overview
Overview
The risk factors for ADEM include:
- Infections (most common)
- Vaccinations
- Genetic predisposition
Risk Factors
Risk Factors
Infections
- The pathogens remain mostly unknown[1].
- The prodromal phase is characterised by flu-like symptoms (56-61%) and non-specific upper respiratory or gastrointestinal manifestations. The latent period varies from 4 to 41 days[2].
- Viral exanthems usually precede the onset of pediatric ADEM[3].
- The most common associated pathogens are viruses namely, Epstein-Barr, measles, mumps, rubella and coxsackie B[4]. Bacteria like Borrelia burgdorferi, Legionella and Mycoplasma are infrequently reported[5][6].
Vaccinations
- Immunisation is the precipitating factor for less than 5% of ADEM cases[7].
- The most frequent occurrences are with measles, mumps and rubella vaccines[8].
- The latent period varies from 2 to 30 days[8].
Genetic susceptibility
- An association between ADEM and HLA-DR genes has been elucidated in a recent study[9].
- Patients with congenital adrenal hyperplasia or acquired adrenal insufficiency have been reported to suffer from sequelae of encephalopathy with white matter lesions[10].
