[Diagnostic value of spinal fluid immunoglobulins in cerebral arachnoiditis].

The authors believe that the deficiency of immunoglobulins A in the cerebrospinal fluid (CSF) of patients with arachnoiditis may be explained by an increase in their consumption due to antigenic aggression in relation to the meninges, which results in extremely low values of the circulating immunoglobulins A. The absence of immunoglobulins A in the CSF of patients with cerebral arachnoiditis is one of the components of its pathogenesis owing to impairment of permeability of the blood brain barrier and fixation of antigens in the tissues of the brain and meninges.
