RESUMO
BACKGROUND: High rates of vitamin D insufficiency are usually found in obese patients, even before any malabsorptive bariatric surgery. It is not clear whether they lack vitamin D because of different food intake, different solar exposure, or different storage pathways or bioavailability in adipose tissue. To better understand vitamin D deficiency, we studied different categories of inpatients. METHODS: We collected clinical and biological data from 457 consecutive inpatients during a year: 217 nonobese diabetic patients, 159 obese nonsurgical diabetic patients, 46 obese surgical nondiabetic patients, and 35 obese surgical diabetic patients. Statistically significant differences between two mean 25-hydroxyvitamin D (25(OH)D) levels were defined at the 5 % level using a Z-test. RESULTS: Vitamin D deficiency was found in 69 % of the patients, while 24 % had a normal level and 7 % an optimal level. A significant difference was found between obese (25(OH)D = 40.3 nmol/l) and nonobese patients (25(OH)D = 46.8 nmol/l). Patients undergoing bariatric surgery were not different from the other obese patients. CONCLUSION: No significant difference in 25(OH) vitamin D level could be demonstrated between obese patients before bariatric surgery and obese patients with no obesity surgery project. No difference was found between our Parisian obese population and a Spanish obese population, which benefits from a better solar exposure. Both findings suggest that obesity itself is the link with vitamin D deficiency, independently from behavioral differences.

OBJECTIVE: High Authority for Health (HAS) edited in April 2011 a national program of care and diagnostic (PNDS) concerning congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency in agreement with the international recommendation 2002 and 2010. To reduce long-term complications and improve the quality of life to our patients, we had tested our professional practices. PATIENTS: All patients aged more than 18 years with classic CAH of the adult endocrine units in the Nancy's University Hospital Center. METHODS: We have made a clinical audit. We checked all medical records to see whether the recommendation were applied or not between the last consultation before (Tour 1; T1) and after (Tour 2; T2) the introduction of the national guidelines. RESULTS: Twenty-seven medicals records with classic CAH were analyzed. The collection of clinical data must be more systematic because if the weight appeared in 89% of cases, body mass index missed (26% only in T1), the measure of the blood pressure remained insufficient (74% in T2). Concerning the therapeutic balance, 17-hydroxyprogestérone, testosterone, renin were correctly prescribed (>80%), Delta4-androstènedione in improvement (from 67% to 100%) some in defect (stable with 68% sodium and potassium). The evaluation of the fertility considerably progressed on the other hand the markers of bone metabolism were still often too much lacking. CONCLUSIONS: Change in compliance since national guidelines is a slow process.
