Epidemiology

This is a rare condition with an incidence estimated to be less that 1 in a million live births. About 100 cases have been reported worldwide. The bulk of cases are sporadic but familial forms with autosomal dominant transmission have also been described.

MRI with contrast may show enhancement of leptomeninges and cochlea consistent with chronic meningitis. EEG shows is non specific with slow waves and spike discharges.

Polymorphs tend to show increased expression of CD10.

The disease is caused in 60% of cases by a mutated gene called CIAS1 that is known to be involved in other syndromes that appear somewhat similar, such as Muckle-Wells syndrome

. In many patients, the parents do not have the same mutation, indicating the problem was not inherited, even though it is a genetic disease.

CIAS1 is involved in controlling the immune system, which is why the mutation leads to out-of-control inflammation.

Diagnosis

The diagnosis is based on observing the patient and finding the constellation of symptoms and signs described above. A few blood tests help, by showing signs of long standing inflammation. There is no specific test for the disease, though now that the gene that causes the disease is known, that may change.

Prognosis

Overall, the prognosis for patients with NOMID is not good, though many (80%) live into adulthood, and a few appear to do relatively well. They are at risk for leukemia, infections, and some develop deposits of protein aggregated called amyloid
