Are patients with Hirschsprung's disease prediabetic?
Hirschsprung's disease (HD) is considered a focal disease usually confined to the distal colon and rectum. However, autonomic dysfunction and dysmotility in the upper gastrointestinal tract have been reported, suggesting that this disease is not only confined to the distal gastrointestinal tract. This study examines the fasting and postprandial levels of glucose and insulin in adult patients with HD to elucidate whether there might also be an endocrine involvement in this disease. Sixteen patients with surgically treated HD during early childhood and 17 healthy subjects were studied. All subjects ingested a caloric liquid meal containing glucose, lactose, maize oil, and water (2,020 kJ) after an overnight fast. Blood samples were collected at regular intervals for insulin and glucose analyses. Fasting levels of both glucose (P <.05) and insulin (P <.02) were significantly higher in patients compared with healthy controls. Peak concentration of insulin following meal intake was significantly higher in the patient group (P <.05), and peak concentration of glucose tended to be higher in patients compared with controls (P =.06). There was no correlation between body mass index and serum levels of glucose or insulin. The present study shows that adult patients treated for HD during childhood have an impaired glucose and insulin homeostasis, indicating a mild degree of insulin resistance. This may imply susceptibility towards development of non-insulin-dependent diabetes mellitus.
