Cell-mediated and humoral immunity in West syndrome

The immunological status of five children with West syndrome consequent to previous cerebral lesions was investigated. Three children had West syndrome and two were in transition from West to Lennox-Gastaut syndrome. All of them showed cellular immunological deficiencies in the following tests: sensitization to DNCB, intracutaneous reaction to PHA, inhibition of leucocyte migration, blastic transformation of lymphocytes, T and B lymphocytes in peripheric blood and levels of serum immunoglobulins. These immunological deficiencies, of different degrees of severity, were associated to frequent infections in these children. A possible association between the immunological deficiencies and autoimmunity is discussed.
