Circulating cytokines are associated with human islet graft function in type 1 diabetes.

Islet cell transplantation has considerable potential as a cure for type 1 diabetes, but recurrent autoimmunity and allograft rejection in which both cytokines play an important role are major obstacles. Using a new approach considering confounders by regression analysis, we investigated circulating cytokines and their association with graft function in type 1 diabetes patients who underwent either simultaneous islet kidney (SIK) or islet after kidney (IAK) transplantation. After transplantation, interleukin (IL)-10 was lower in SIK recipients with subsequent loss of graft function in comparison to recipients maintaining graft function.

Distinct autoantibodies against exocrine pancreatic antigens in European patients with type 1 diabetes mellitus and non-alcoholic chronic pancreatitis.

Context: Histopathological analysis has demonstrated lymphocytic infiltration in both the endocrine and the exocrine pancreas in some patients with type 1 diabetes and non-alcoholic chronic pancreatitis, suggesting an immune-mediated mechanism which affects both diabetes mellitus and chronic pancreatitis.

Objective: The examination of exocrine pancreatic humoral markers in Caucasian patients with respect to the interactions between exocrine and endocrine pancreatic diseases.

Patients: One hundred and thirty-six European Caucasian subjects subdivided into three groups: type 1 diabetes (n=48); non-alcoholic chronic pancreatitis (n=48); controls (n=40).

High prevalence of steatorrhea in 101 diabetic patients likely to suffer from exocrine pancreatic insufficiency according to low fecal elastase 1 concentrations: a prospective multicenter study.

Impaired exocrine pancreatic secretion has been frequently observed in diabetic patients by different methods, including direct function tests. However, the clinical importance remained unclear. In the present study, the fecal fat excretion in patients with type 1 or type 2 diabetes mellitus and exocrine dysfunction according to fecal elastase 1 concentrations <100 microg/g was investigated.

High prevalence of exocrine pancreatic insufficiency in diabetes mellitus. A multicenter study screening fecal elastase 1 concentrations in 1,021 diabetic patients.

Background: There have been numerous reports on pancreatic exocrine dysfunction in diabetes mellitus using either direct or indirect function tests. The measurement of fecal elastase 1 concentrations (FEC) has been used as a screening tool for exocrine pancreatic disease in different patient groups indicating a high prevalence of exocrine dysfunction in diabetic populations. In this study we had the opportunity to study more than 1,000 diabetic patients to confirm recent observations in smaller populations.
