In a previous work we demonstrated a strong association between HLA-B7 and the susceptibility to the Lennox-Gastaut syndrome. In this work we report some preliminary results obtained performing one-way mixed lymphocyte cultures in vitro between 15 unrelated children showing the typical EEG and clinical patterns of the syndrome. The same children were also tested against unrelated control cells from healthy donors. The low stimulation displayed by Lennox-Gastaut patients between them as compared with the higher stimulation found in patients/controls and controls/controls comparisons suggests the existence of an LD allele which may be associated with the disease.

21 new cases of infantile spasms were reported in 1976 from paediatric departments in Denmark. The connection between infantile spasms and the Lennox-Gastaut syndrome is mentioned, because of reports of a significantly higher incidence of HLA-B7 in children with Lennox-Gastaut syndrome. The HLA antigen distribution in 19 of the 21 children was compared with that of 1967 healthy adults. No difference in the HLA antigens was demonstrated between children with infantile spasms and controls, whether in the material as a whole, or in the cryptogenic or symptomatic groups. However HLA typing of children with infantile spasms should continue in the search for a potential genetic marker in this grave disease, particularly in view of the reported high incidence of HLA-B7 in children with the Lennox-Gastaut syndrome.

Serologic HLA typing was performed on 12 patients with cryptogenic Lennox-Gastaut syndrome and compared to a normal control group of 1661 Caucasians. In the Lennox-Gastaut group we found a significant increase in the frequency of DR5 antigen (55%, chi 2 = 5.6), and an indication of a decrease in the frequency of DR4 antigen (0%, chi 2 = 3.0) as compared with controls (20% and 28%, respectively). No significant differences existed in the frequencies of HLA-A, B, and C antigens between the Lennox-Gastaut group and the controls. These findings contribute to the hypothesis that immunogenetic mechanisms may play a role in triggering or maintaining cryptogenic Lennox-Gastaut syndrome.
