BACKGROUNDA new inhalable insulin aerosol (Inh-Ins) was developed in China. The aim of this multicenter clinical study was to evaluate the efficacy and safety of this new Inh-Ins as a treatment of type 2 diabetes. Regular porcine insulin (RI) was used as a control.

METHODSThis study is a prospective, randomized, open-label, parallel-group multicenter clinical trial in which 253 qualified patients with type 2 diabetes received the insulin Glargine daily at bedtime plus either a pre-meal Inh-Ins or a pre-meal subcutaneous RI for 12 weeks. HbA1c, fasting plasma glucose (FPG), the 1-hour-postprandial blood glucose (1hPBG) and the 2-hour-postprandial blood glucose (2hPBG) were measured. Events were monitored for adverse effects.

RESULTSAfter 12 weeks, the HbA1c decreased significantly from baseline in both treatment groups, with no significant difference between the two regimens. In the Inh-Ins group, FPG, both 1hPBG and 2hPBG significantly declined from baseline after the 8th- and 12th-weeks of treatment. The reduced values of FPG or 1hPBG between the two groups showed a more significant hypoglycemic effect with the Inh-Ins than the RI. After 12 weeks, the pulmonary carbon monoxide diffusing capacity (DLco) was significantly lower in Inh-Ins group than in the RI. The main side effects of Inh-Ins were coughing, excessive sputum, and hypoglycemia.

CONCLUSIONSInh-Ins was effective in decreasing HbA1c like the RI. It was better in lowering the FPG and the 1hPBG than the RI. Its main side effects were coughing, excessive sputum, and hypoglycemia. Also, Inh-Ins slightly impaired DLco.

Hypoglycemia is a common finding in both daily clinical practice and acute care settings. The causes of severe hypoglycemia (SH) are multi-factorial and the major etiologies are iatrogenic, infectious diseases with sepsis and tumor or autoimmune diseases. With the advent of aggressive lowering of HbA1c values to achieve optimal glycemic control, patients are at increased risk of hypoglycemic episodes. Iatrogenic hypoglycemia can cause recurrent morbidity, sometime irreversible neurologic complications and even death, and further preclude maintenance of euglycemia over a lifetime of diabetes. Recent studies have shown that hypoglycemia is associated with adverse outcomes in many acute illnesses. In addition, hypoglycemia is associated with increased mortality among elderly and non-diabetic hospitalized patients. Clinicians should have high clinical suspicion of subtle symptoms of hypoglycemia and provide prompt treatment. Clinicians should know that hypoglycemia is associated with considerable adverse outcomes in many acute critical illnesses. In order to reduce hypoglycemia-associated morbidity and mortality, timely health education programs and close monitoring should be applied to those diabetic patients presenting to the Emergency Department with SH. ED disposition strategies should be further validated and justified to achieve balance between the benefits of euglycemia and the risks of SH. We discuss relevant issues regarding hypoglycemia in emergency and critical care settings.

Objective: To systematically evaluate the correlation between prenatal steroid exposure and hypoglycemia in late preterm neonates. Methods: Eight databases in either Chinese or English, including PubMed, the Cochrane Library, Embase, Medline, Scopus, CNKI, Wanfang and VIP, were searched to extract the studies on the correlation between prenatal steroid exposure and hypoglycemia in late preterm neonates published from the establishment of each database to December 2022. The Meta-analysis was performed using Stata 14.0 statistical software. Results: A total of 9 studies were included in this Meta-analysis, including 6 retrospective cohort studies, 2 prospective cohort studies and 1 randomized controlled trial (RCT) study, involving 9 143 premature infants. The Meta-analysis showed that prenatal steroid exposure increased the risk of late preterm neonatal hypoglycemia (RR=1.55, 95%CI 1.25-1.91, P<0.001). The similar correlation between prenatal steroid exposure and hypoglycemia in late preterm neonates was all found in the following subgroups: North America (RR=1.57, 95%CI 1.37-1.80, P<0.001), enrolling pregnant women with gestational diabetes (RR=1.62, 95%CI 1.26-2.08, P<0.001), A-grade literature quality (RR=1.43, 95%CI 1.14-1.79, P=0.002), criteria for hypoglycemia ≤40 mg/dl (1 mg/dl=0.056 mmol/L, RR=1.49, 95%CI 1.28-1.73, P<0.001), sample size of 501-1 500 (RR=1.69, 95%CI 1.19-2.40, P=0.003) and >1 500 (RR=1.65, 95%CI 1.48-1.83, P<0.001), steroid injection dosage and frequency of 12 mg 2 times (RR=1.66, 95%CI 1.50-1.84, P<0.001), the time interval from antenatal corticosteroid administration to delivery of 24-47 h (RR=1.98, 95%CI 1.26-3.10, P=0.003), unadjusted gestational age (RR=1.78, 95%CI 1.02-3.10,P=0.043) and unadjusted birth weight (RR=1.80, 95%CI 1.22-2.66, P=0.003). Meta-regression results showed that steroid injection frequency and dose were the main sources of high heterogeneity among studies (P=0.030). Conclusion: Prenatal steroid exposure may be a risk factor for hypoglycemia in late preterm neonates.

BACKGROUND/AIMS: To investigate abnormalities in blood electrolyte levels during severe hypoglycemia in Korean patients with type 2 diabetes mellitus (T2DM) in a clinical setting. METHODS: Blood electrolyte levels in adult T2DM patients during severe hypoglycemia were collected from January 1, 2008 to December 31, 2012. Patients who maintained normal serum creatinine and blood urea nitrogen levels were utilized in the study. Severe hypoglycemia was defined as a condition requiring medical assistance, such as administering carbohydrates when serum glucose levels less than 70 mg/dL were observed, in conjunction with other symptoms of hypoglycemia. RESULTS: A total of 1,068 patients who visited the emergency room with severe hypoglycemia were screened, of which 219 patients were included in this study. The incidence of abnormal levels for any electrolyte was 47%. Hypokalemia (< 3.5 mmol/L) was the most common type of electrolyte disturbance observed at 21.9%. A decrease in serum potassium levels was associated with decreases in blood glucose levels (r = 0.151, p = 0.025). During severe hypoglycemia, median blood glucose levels, incidence of tachycardia (> 100 beats per minute) and severe hypertension (> or = 180/120 mmHg) were 30 mg/dL (range, 14 to 62) and 35 mg/dL (range, 10 to 69; p = 0.04), 18.8% and 7.2% (p = 0.02), and 20.8% and 10.2% (p = 0.05) in the hypokalemia and normokalemia groups, respectively. CONCLUSIONS: During severe hypoglycemia, hypokalemia occurred in 21.9% of T2DM patients and was associated with tachycardia and severe hypertension. Therefore, the results suggest that severe hypoglycemia may increase cardiovascular events in T2DM.

To establish the parsimonious model for blood glucose monitoring in patients with type 2 diabetes receiving oral hypoglycemic agent treatment. One hundred and fifty-nine adult Chinese type 2 diabetes patients were randomized to receive rapid-acting or sustained-release gliclazide therapy for 12 weeks. Their blood glucose levels were measured at 10 time points in a 24 h period before and after treatment, and the 24 h mean blood glucose levels were measured. Contribution of blood glucose levels to the mean blood glucose level and HbA1c was assessed by multiple regression analysis. The correlation coefficients of blood glucose level measured at 10 time points to the daily MBG were 0.58-0.74 and 0.59-0.79, respectively, before and after treatment (P<0.0001). The multiple stepwise regression analysis showed that the blood glucose levels measured at 6 of the 10 time points could explain 95% and 97% of the changes in MBG before and after treatment. The three blood glucose levels, which were measured at fasting, 2 h after breakfast and before dinner, of the 10 time points could explain 84% and 86% of the changes in MBG before and after treatment, but could only explain 36% and 26% of the changes in HbA1c before and after treatment, and they had a poorer correlation with the HbA1c than with the 24 h MBG. The blood glucose levels measured at fasting, 2 h after breakfast and before dinner truly reflected the change 24 h blood glucose level, suggesting that they are appropriate for the self-monitoring of blood glucose levels in diabetes patients receiving oral anti-diabetes therapy.

BACKGROUNDIncretin-based therapies provide additional options for treating type 2 diabetes. We aimed to evaluate the efficacy and tolerability of exenatide monotherapy in obese patients with type 2 diabetes.

METHODSA 26-week, metformin controlled, parallel-group study was conducted among antidiabetic drug-naive obese patients aged > 18 years, and with type 2 diabetes. Participating patients were randomly assigned to receive exenatide or metformin treatments.

RESULTSFifty-nine patients (age (50.5 ± 8.6) years, body mass index (BMI) (30.2 ± 1.6) kg/m(2), and hemoglobin A1C (HbA(1C) (8.2 ± 1.2)%) were enrolled in the study. Glucose control and weight reduction improved in both groups receiving treatment. HbA(1C) and oral glucose tolerance test (OGTT) 2 hour glycemia reduction with exenatide was superior to that obtained with metformin ((-2.10 ± 1.79)% vs. (-1.66 ± 1.38)%, (-5.11 ± 2.68) mmol/L vs. (-2.80 ± 2.70) mmol/L, P < 0.05). Fast plasma glucose (FPG) reduction was not significantly different between the two groups ((-1.8 ± 2.0) mmol/L vs. (-1.6 ± 1.7) mmol/L, P > 0.05). Patients treated with exenatide achieved HbA(1C) of < 7% (97% of patients) and < 6.5% (79%) at end-point, vs. 93% and 73% with metformin (P > 0.05). Greater weight reduction was also achieved with exenatide ((-5.80 ± 3.66) kg) than with metformin ((-3.81 ± 1.38) kg, P < 0.01). Homeostasis model assessment of beta-cell function (HOMA-B) was not significantly increased, but the insulinogenic index and HOMA for insulin sensitivity (HOMA-S) were greatly improved in the exenatide group (P < 0.05). Nausea was the most common adverse effect in exenatide treatment (30% vs. 8%; P < 0.05), but most cases were of mild to moderate intensity. One case in the exenatide group was withdrawn early because of severe nausea. Hypoglycemia events were often observed during the first 4 weeks, with 12% of patients in the exenatide and 3.2% in metformin groups, respectively (P < 0.05). No incidents of severe hypoglycemia were reported.

CONCLUSIONSExenatide demonstrated more beneficial effects on HbA(1C), weight reduction and insulin resistance during 26 weeks of treatment, but there were more hypoglycemic events and mild-to-moderate nausea compared with metformin. These results suggested that exenatide monotherapy may provide a viable treatment option in newly developed type 2 diabetes.

Hypoglycemia is a major barrier to achieving the glycemic goal in patients with type 2 diabetes. In particular, severe hypoglycemia, which is defined as an event that requires the assistance of another person to actively administer carbohydrates, glucagon, or take other corrective actions, is a serious clinical concern in patients with diabetes. If severe hypoglycemia is not managed promptly, it can be life threatening. Hypoglycemia-associated autonomic failure (HAAF) is the main pathogenic mechanism behind severe hypoglycemia. Defective glucose counter-regulation (altered insulin secretion, glucagon secretion, and an attenuated increase in epinephrine during hypoglycemia) and a lack of awareness regarding hypoglycemia (attenuated sympathoadrenal activity) are common components of HAAF in patients with diabetes. There is considerable evidence that hypoglycemia is an independent risk factor for cardiovascular disease. In addition, hypoglycemia has a significant influence on the quality of life of patients with diabetes. To prevent hypoglycemic events, the setting of glycemic goals should be individualized, particularly in elderly individuals or patients with complicated or advanced type 2 diabetes. Patients at high-risk for the future development of severe hypoglycemia should be selected carefully, and intensive education with reinforcement should be implemented.

OBJECTIVETo study the anti-hyperglycemic effect and its mechanism of Dendrobium candidum (DC).

METHODNormal mice, adrenaline-induced hyperglycemic mice, streptozotocin-induced diabetic (STZ-DM) rats were used. The mechanisms of the anti-hyperglycemic action were studied with radio-immunoassay, immunohistochemical HRP-SPA stain, etc.

RESULTDC could not obviously decrease the serum glucose concentrations and insulin levels in normal mice. It could increase serum insulin levels and decrease serum glucagons concentrations in STZ-DM rats. The results of immunohistochemical stain demonstrated that the number of islet beta cells was increased and that of islet a cells was decreased in STZ-DM rats. It could also decrease the serum glucose concentrations and increase liver glucogen contents in adrenaline-induced hyperglycemic mice.

CONCLUSIONDC has obvious anti-hyperglycemic effects in adrenaline-induced hyperglycemic mice and STZ-DM rats. Its mechanisms are stimulating the secretion of insulin from beta cells and inhibiting the secretion of glucagons from a cells, and it can probably decrease the decomposition of liver glucogen and increase the synthesis of liver glucogen.
