title: In vivo determination of cell mediated immune response in diabetic patients using a multiple intradermal antigen dispenser.
abstract: The in vivo cell mediated immune response using a multiple intradermal antigen dispenser (Multitest) was evaluated in 99 diabetic patients (24 Type I and 75 Type II) and in 50 age matched normal subjects. Seven different antigens (tetanus, diphteria, streptococcus, tubercoline, candida, trichophyton, proteus and a glycerine control) were applied in the forearm and the induration for the antigens tested was measured 48 hours later. A score was calculated adding the arithmetic means obtained with each single antigen. Overall we did not find major differences between diabetic patients and controls except Type I patients of shorter duration (less than 5 years) having a reduced response (p less than 0.05) and both Type I and Type II patients showing an elevated response to candida antigen (p less than 0.001). No correlation was found between the intradermal response and metabolic control. As the intradermal test is a model for delayed type of hypersensitivity, these data suggest that the in vivo lymphocyte to lymphocyte cooperation in patients with long standing diabetes is not impaired.
