- Aim: Diabetes mellitus type 1 (T1D) has numerous complications including autonomic neuropathy, i.e. dysfunction of the autonomous nervous system. This study focuses on Heat Shock Protein 27 (HSP27), Macrophage Migration Inhibitory Factor (MIF), Plasminogen Activator Inhibitor-1 (PAI-1) and HbA1c and their possible roles in effects of diabetes on the autonomic nervous system. Methods: Patients with T1D (n = 32, 41% women) were recruited in 1985 and followed up on four occasions (1989, 1993, 1998, and 2005). Autonomic function was tested using expiration/inspiration (E/I-ratio). Blood samples, i.e . HSP27 (last three occasions), MIF, PAI-1 (last two occasions) and HbA1c (five occasions), were analyzed. Results: Autonomic nerve function deteriorated over time during the 20-year-period, but levels of HSP27, MIF, and PAI-1 were not associated with cardiovascular autonomic neuropathy. MIF and PAI-1 were lower in T1D than in healthy controls in 2005. Increased HbA1c correlated with a decrease in E/I-ratio. Conclusions: Neither the neuroprotective substance HSP27 nor the inflammatory substances, MIF and PAI-1 were associated with measures of cardiovascular autonomic nerve function, but a deterioration of such function was observed in relation to increasing HbA1c in T1D during a 20-year follow-up period. Improved glucose control might be associated with protection against autonomic neuropathy in T1D.
