RESUMO
BACKGROUND: Studies comparing the use of basal bolus with insulin analogs vs. split-mixed regimens with human insulins in hospitalized patients with type 2 diabetes are lacking. RESEARCH DESIGN AND METHODS: In a controlled multicenter trial, we randomized 130 nonsurgical patients with blood glucose (BG) between 140 and 400 mg/dl to receive detemir once daily and aspart before meals (n = 67) or neutral protamine Hagedorn (NPH) and regular insulin twice daily (n = 63). Insulin dose was started at 0.4 U/kg.d for BG between 140 and 200 mg/dl or 0.5 U/kg.d for BG 201-400 mg/dl. Major study outcomes included differences in mean daily BG levels and frequency of hypoglycemic events between treatment groups. RESULTS: Glycemic control improved similarly in both groups from a mean daily BG of 228 +/- 54 and 223 +/- 58 mg/dl (P = 0.61) to a mean daily BG level after the first day of 160 +/- 38 and 158 +/- 51 mg/dl in the detemir/aspart and NPH/regular insulin groups, respectively (P = 0.80). A BG target below 140 mg/dl before meals was achieved in 45% of patients in the detemir/aspart group and 48% in the NPH/regular group (P = 0.86). During treatment, 22 patients (32.8%) in the detemir/aspart group and 16 patients (25.4%) in the NPH/regular group had at least one episode of hypoglycemia (BG < 60 mg/dl) during the hospital stay (P = 0.34). CONCLUSIONS: Treatment with basal/bolus regimen with detemir once daily and aspart before meals results in equivalent glycemic control and no differences in the frequency of hypoglycemia compared to a split-mixed regimen of NPH and regular insulin in patients with type 2 diabetes.

BACKGROUND: Female pseudohermaphroditism is a disorder in which 46,XX females with ovaries do not develop as normal women. This disorder is caused by overexposure of a female fetus to androgens during intrauterine life. We describe a masculinized female infant who was born to a mother who had virilizing signs. PATIENT REPORT: The patient had a normally formed phallus and a completely fused scrotum. Baseline as well as stimulated adrenal hormones and testosterone values were in the normal range in the infant. No androgens were given to the mother during pregnancy. Serum 17-OHP, DHEA-S, and testosterone levels were all elevated in the mother. Imaging studies revealed a tumor mass over the left kidney pole. Histologically it was an adrenal tumor. CONCLUSIONS: Although a maternal adrenal tumor is a rare cause of female pseudohermaphroditism, the physician must bear this in mind when confronted with a newborn or infant with 46,XX karyotype and cryptorchidism with a phallic urethra.

OBJECTIVE: The optimal treatment of hyperglycemia in general surgical patients with type 2 diabetes mellitus is not known. RESEARCH DESIGN AND METHODS: This randomized multicenter trial compared the safety and efficacy of a basal-bolus insulin regimen with glargine once daily and glulisine before meals (n = 104) to sliding scale regular insulin (SSI) four times daily (n = 107) in patients with type 2 diabetes mellitus undergoing general surgery. Outcomes included differences in daily blood glucose (BG) and a composite of postoperative complications including wound infection, pneumonia, bacteremia, and respiratory and acute renal failure. RESULTS: The mean daily glucose concentration after the 1st day of basal-bolus insulin and SSI was 145 ± 32 mg/dL and 172 ± 47 mg/dL, respectively (P < 0.01). Glucose readings <140 mg/dL were recorded in 55% of patients in basal-bolus and 31% in the SSI group (P < 0.001). There were reductions with basal-bolus as compared with SSI in the composite outcome [24.3 and 8.6%; odds ratio 3.39 (95% CI 1.50-7.65); P = 0.003]. Glucose <70 mg/dL was reported in 23.1% of patients in the basal-bolus group and 4.7% in the SSI group (P < 0.001), but there were no significant differences in the frequency of BG <40 mg/dL between groups (P = 0.057). CONCLUSIONS: Basal-bolus treatment with glargine once daily plus glulisine before meals improved glycemic control and reduced hospital complications compared with SSI in general surgery patients. Our study indicates that a basal-bolus insulin regimen is preferred over SSI in the hospital management of general surgery patients with type 2 diabetes.

PURPOSE: To compare the safety and efficacy of continuous insulin infusion (CII) via a computer-guided and a standard paper form protocol in a medical intensive care unit (ICU). METHODS: Multicenter randomized trial of 153 ICU patients randomized to CII using the Glucommander (n = 77) or a standard paper protocol (n = 76). Both protocols used glulisine insulin and targeted blood glucose (BG) between 80 mg/dL and 120 mg/dL. RESULTS: The Glucommander resulted in a lower mean BG value (103 ± 8.8 mg/dL vs. 117 ± 16.5 mg/dL, P < 0.001) and in a shorter time to reach BG target (4.8 ± 2.8 vs.7.8 hours ± 9.1 hours, P < 0.01), and once at target resulted in a higher percentage of BG readings within target (71.0 ± 17.0% vs. 51.3 ± 19.7%, P < 0.001) than the standard protocol. Mean insulin infusion rate in the Glucommander was similar to the standard protocol (P = 0.12). The percentages of patients with ≥1 episode of BG <40 mg/dL and <60 mg/dL were 3.9% and 42.9% in the Glucommander and 5.6% and 31.9% in the standard, respectively [P = not significant (NS)]. Repeated measures analyses show that the probabilities of BG reading <40 mg/dL or <60 mg/dL were not significantly different between groups (P = 0.969, P = 0.084) after accounting for within-patient correlations with or without adjusting for time effect. There were no differences between groups in the length of hospital stay (P = 0.704), ICU stay (P = 0.145), or inhospital mortality (P = 0.561). CONCLUSION: Both treatment algorithms resulted in significant improvement in glycemic control in critically ill patients in the medical ICU. The computer-based algorithm resulted in tighter glycemic control without an increased risk of hypoglycemic events compared to the standard paper protocol.

OBJECTIVE: To compare the safety and efficacy of insulin analogs and human insulins both during acute intravenous treatment and during the transition to subcutaneous insulin in patients with diabetic ketoacidosis (DKA). RESEARCH DESIGN AND METHODS: In a controlled multicenter and open-label trial, we randomly assigned patients with DKA to receive intravenous treatment with regular or glulisine insulin until resolution of DKA. After resolution of ketoacidosis, patients treated with intravenous regular insulin were transitioned to subcutaneous NPH and regular insulin twice daily (n = 34). Patients treated with intravenous glulisine insulin were transitioned to subcutaneous glargine once daily and glulisine before meals (n = 34). RESULTS: There were no differences in the mean duration of treatment or in the amount of insulin infusion until resolution of DKA between intravenous treatment with regular and glulisine insulin. After transition to subcutaneous insulin, there were no differences in mean daily blood glucose levels, but patients treated with NPH and regular insulin had a higher rate of hypoglycemia (blood glucose <70 mg/dl). Fourteen patients (41%) treated with NPH and regular insulin had 26 episodes of hypoglycemia and 5 patients (15%) in the glargine and glulisine group had 8 episodes of hypoglycemia (P = 0.03). CONCLUSIONS: Regular and glulisine insulin are equally effective during the acute treatment of DKA. A transition to subcutaneous glargine and glulisine after resolution of DKA resulted in similar glycemic control but in a lower rate of hypoglycemia than with NPH and regular insulin. Thus, a basal bolus regimen with glargine and glulisine is safer and should be preferred over NPH and regular insulin after the resolution of DKA.

A higher incidence of Y-chromosome microdeletions was found on gonadal DNA than on peripheral blood lymphocyte DNA and on streak gonads than on dysgenetic testis in 11 patients with 45,X/46,XY gonadal dysgenesis. It is probable that an association between Y-chromosome microdeletions and severity of the phenotype in 45,X/46,XY patients exists.
