RESUMEN
OBJECTIVE: To assess the quality of life and metabolic control in patients with diabetes mellitus type 1 on continuous subcutaneous insulin infusion (CSII) in comparison with patients on multiple daily insulin injections (MDII). RESEARCH DESIGN AND METHODS: The study included 49 patients (13 males, 36 females), aged 41.4+/-11.3 years (mean+/-SD) on CSII for >1 year and 79 patients (43 males, 36 females), aged 43.1+/-14.8 years on MDII for >1 year, from three Dutch diabetic clinics. There were no statistically significant differences in duration of diabetes, social class, level of education, marital status, smoking or recent admissions to hospital. The questionnaires used were a Diabetes Quality of Life scale adapted from the DCCT, the Diabetes Satisfaction Questionnaire (DTSQ), and the WHO Well-Being Questionnaire. HbA1c was measured with an HPLC method (reference range 4.3 to 6.1 %). RESULTS: Using two-sided t-tests no statiscally significant differences were found between the patients on CSII and MDII with respect to quality of life (version A (<30 years) 4.32+/-0.22 vs 4.20+/-0.30; version B (> or =30 years) 4.18+/-0.25 vs 4.29+/-0.28), well-being (48.59+/-9.23 vs 50.99 +/-8.70), satisfaction with treatment (5.10+/-0.69 vs 5.15+/-0.71) and HbA1c (8.14+/-1.51 vs 8.47+/-1.40). Frequency of daily blood glucose monitoring was slightly higher in CSII than in MDII patients (4.52+/-1.19 vs 3.60+/-1.47; p<0.0001). CONCLUSION: The present data indicate that patients on CSII have similar QoL based on questionnaires when compared with patients on MDII. These data suggest that in patients with less optimal control on MDII, converting the treatment strategy to CSII is not associated with decreased quality of life.

Since 1975, 10 families with the multiple endocrine neoplasia (MEN)-2A syndrome and five with the MEN-2B syndrome, making a total of 101 patients, have been identified in The Netherlands. Twenty-three of the MEN-2A patients died before the start of the screening program. The average age of the patients whose death was due to pheochromocytoma (n = 11) or medullary thyroid carcinoma (n = 12) was 34.9 and 49.2 years, respectively. Eighty-seven patients with the MEN-2A syndrome and eight with the MEN-2B syndrome underwent thyroidectomy for C-cell hyperplasia and/or medullary thyroid carcinoma. Eighteen patients had signs or symptoms caused by MEN-2A (group A), 60 were relatives of these patients who had been found to be affected at the first screening of the family (group B), and nine relatives had had negative screening results that later became positive (group C). Five patients had signs or symptoms due to MEN-2B (group A) and three were relatives of these patients who had been found to be affected at the initial screening (group B). To assess the effect of screening, we compared these groups with respect to the occurrence of metastatic medullary thyroid carcinoma at thyroidectomy and the results of the postoperative calcitonin tests. Among the MEN-2A families, 72 percent of group A, 33 percent of group B, and none of group C were found to have metastatic medullary thyroid carcinoma at surgery. In the MEN-2B families, all five patients in group A and one of the three patients in group B had metastatic disease. The "cure rates" in these three groups with MEN-2A, as determined by stimulated calcitonin assessment, were 11, 57, and 100 percent, respectively. One of the five patients with MEN-2B in group A and two of the three patients in group B showed normalization of the stimulated calcitonin value after surgery. From these results, it may be concluded that screening can lead to the detection of medullary thyroid carcinoma in an earlier stage, which in turn may permit curative treatment and improvement of both prognosis and life expectancy. The need for supervision of affected families by central registration to promote periodic examination and to guarantee the continuity of such screening is discussed.
