title: Cell-mediated and humoral immune responses in patients with localized juvenile periodontitis.
abstract: Cell-mediated and humoral immune responses were assessed in 21 patients with localized juvenile periodontitis (LJP), and in an equal number of control subjects. The cell-mediated immunity, assessed by enumeration of total rosette forming cells [TRFC] and high affinity rosette forming cells [HARFC], was found to be depressed in LJP patients compared to controls. Estimation of serum immunoglobulins G,A,M,D and E levels were done using single radial immunodiffusion. All the immunoglobulins except IgD were found to be elevated significantly in LJP patients. The defective immune response found in LJP patients may be the cause or effect of the disease process. Further investigations are necessary to determine whether these defects are genetically controlled.
