 AB    There has been a growing body of evidence suggesting that CD4+ Th1/Th2
       cell responses participate in pathologic and immunologic processes in
       infectious disease. Bacterial meningitis is a fatal disease of children
       and is associated with a spectrum of clinical syndromes. This study
       provides evidence of CD4+ enhanced interleukin (IL)-4 and IL-6 but
       decreased IL-2 and interferon-gamma (IFN-gamma) production, the
       induction of characteristic Th2 cell response cytokines in bacterial
       meningitis, which may play an important role in disease mechanism.
       Additionally, monocyte-induced enhanced IL-6, IL-8, and tumor necrosis
       factor-alpha production may be associated with distinct clinical
       features such as fever, seizures, and neurological sequelae. A striking
       finding was also the highly deficient monocyte-induced
       granulocyte-macrophage colony-stimulating factor production. Of
       particular interest, the CD(8+)-enhanced IFN-gamma production may be
       required for the cytolytic activity or protective response to be
       maintained in this disease. Taken together, these data reveal that
       monocytes and CD4+ (Th2) and CD8+ subsets produce distinct cytokines in
       bacterial meningitis, which may exert an immunoregulatory and
       immunopathologic effect and thus mediate some of the clinical
       manifestations of the disease.
