RESUMEN
OBJECTIVE: To compare the effectiveness of two intensified insulin regimens, i.e., pump delivery versus multiple daily injections in patients with type 2 diabetes not optimally controlled with conventional insulin therapy. RESEARCH DESIGN AND METHODS: Seventeen type 2 diabetes patients uncontrolled by two daily injections of regular plus NPH were randomly assigned in a cross-over fashion to either three daily injections of lispro plus NPH or pump device delivering lispro. HbA1c, 6 points capillary blood glucose, 24-hour continuous glucose monitoring system tracings and global satisfaction score were evaluated at the end of each 12-week treatment period. RESULTS: HbA1c decreased from 9.0+/-1.6% to 8.6+/-1.6% with multiple injections and 7.7+/-0.8% with pump device (p<0.03). Capillary blood glucose was lowered at all time-points with pump, but only at morning with multiple injections (p<0.01). Compared to conventional therapy, pump reduced hyperglycemic area under curve by 73% (p<0.01), but multiple injections by only 32% (p=0.08). Rate of hypoglycemia was not increased and patient's satisfaction was comparable with both intensive treatments. CONCLUSIONS: Pump therapy provides a better metabolic control than injection regimens, and seems to be safe and convenient in patients with type 2 diabetes who fail to respond to conventional insulin therapy.

The increases in the level of plasma lipotropin (LPH) and in the LPH/ACTH ratio are considered diagnostic tools in ectopic ACTH syndrome. However, plasma ACTH is also elevated in this syndrome. We report a case of a small carcinoid tumor with an increase in both ACTH and LPH in plasma before surgery. Eight months after the tumoral resection, plasma LPH alone was increased again, whereas plasma ACTH and plasma and urinary cortisol remained normal in this apparently cured patient. This repeated abnormality was the only available feature that allowed successful removal of the occult tumoral residue.
