title: [Relation between cardiovascular and gastrointestinal neuropathy in diabetics].
abstract: BACKGROUND
  The presence of autonomic neuropathy impairs the quality of life (orthostatic hypotension, impotence, gastroparesis) or endangers the life of diabetics (sudden death, unawareness of hypoglycemia). The purpose of the investigation was: 1. To assess the presence of the autonomic neuropathy of the cardiovascular and the gastrointestinal systems and their mutual relationship. 2. To assess the relationship of found autonomic neuropathy and the subjective symptoms which are typical to affected particular systems (cardiovascular, gastrointestinal, genitourinary, sudomotor systems and the syndrome of unawareness of hypoglycemia).
  
  
  RESULTS
  The group comprised of 25 type 1 diabetic patients (12 women and 13 men) mean age 40.5 +/- 11.6 (range 21-57 years) with a mean duration of diabetes of 17.8 +/- 7.9 (range 4-35 years), treated with intensified insulin regimens. The cardiovascular autonomic neuropathy was automatically examined by the VariaPulse TF 3 computer system. Scintigraphy was used to investigate the gastric emptying time of 99mTc labelled rice. The information about the subjective symptoms we collected from the questionnaire. For statistic analysis we used Spearmen correlations and ANOVA.
  
  
  RESULTS
  1. A statistically significant correlation was found between the presence of the autonomic neuropathy of cardiovascular and gastrointestinal systems (r = 0.634, p < 0.0007). 2. We didn't find any relation among the cardiovascular autonomic neuropathy and the subjective symptoms of cardiovascular system, respectively the gastrointestinal neuropathy (impair gastric emptying) and the subjective symptoms of gastrointestinal system. We found a significant correlation between cardiovascular and gastrointestinal neuropathy and erectile dysfunction (r = 0.48, p < 0.0078), (r = 0.42, p < 0.0388) and with the syndrome of hypoglycemia unawareness (r = 0.49, p < 0.0057), (r = 0.52, p < 0.0075).
  
  
  CONCLUSIONS
  The evidence of the cardiovascular autonomic neuropathy is warning signal for the affected autonomic neuropathy in other systems which are more complicated for diagnostic. The subjective symptoms don't correlate with the presence of the visceral neuropathy.
