AIMS: The objective of the present investigation was to study the production of IL-1, IL-6, IL-10, IFNgamma and TNFalpha in cultures of peripheral blood mononuclear cells (PBMC) taken from type 1 diabetic patients with inadequate metabolic control. METHODS: Seventeen type 1 diabetic patients and a gender- and age-matched group of 17 healthy individuals were studied. PBMC cultures were stimulated with phytohemagglutinin (PHA; 20 microg/ml) and lipopolysaccharide (LPS; 10 microg/ml), and enzyme immunoassay (Elisa) was used to measure IL-1, IL-6, IL-10, IFNgamma and TNFalpha in the cell-culture supernatants. RESULTS: IFNgamma levels in PHA-stimulated cultures were lower in the type 1 diabetics than in the non-diabetic controls (P<0.0001) while, in contrast, IL-10 levels were increased in the PHA-stimulated culture supernatants of the diabetics compared with the controls (P<0.0001). In addition, supernatant levels of the cytokines IL-1, IL-6 and TNFalpha released in the presence of LPS in the cell cultures from the diabetic patients were significantly lower than in the non-diabetic subjects (P<0.0001, P<0.0001 and P<0.03, respectively). CONCLUSIONS: The impaired production of IL-1, IL-6, TNFalpha and IFNgamma, and the increased production of IL-10, in PBMC cultures from type 1 diabetics with inadequate metabolic control compared with healthy subjects may be an indication of a deficiency in mononuclear cell activation and, consequently, a deficient immune cellular adaptive response that, in turn, may be the cause of the increased incidence of infections in people with type 1 diabetes.
